摘要： A clamping device especially adapted for grounding a plurality of electrically conductive members includes a base having two flat parallel faces and a well formed centrally thereof with side surfaces extending between the flat faces being arcuately shaped. The clamp also includes a cover having a post adapted to be received in the well in the base and two arms depending arcuately from opposite sides of the post. When the post is received in the well, the depending arms of the cover cooperate with the arcuate surfaces of the base to form arcuately shaped openings of generally constant width for receiving the conductive members. Securing facilities are used to draw the post within the well and thereby clamp conductive members inserted in the arcuate openings. The configuration causes equal clamping forces to be applied to each of the plurality of conductive members and also causes shear forces to be applied to the outer surface of each conductive member to remove any undesirable surface layer therefrom and thereby improve the electrical connection between the conductive member and the clamp. The securing facilities include provisions for compensating for relaxation due to plastic flow of the materials of the conductive members over a period of time.

摘要： Microcracks in ceramic substrates are detected by positioning a piezoelectric transducer proximate a supporting base for the substrate. The stress waves which are emitted by the cracks which form in the substrate when it is subjected to a load are converted into electrical pulses by the transducer. Because ceramic is a brittle material rather than ductile these pulses are of low amplitude, short duration, and fast rise time. Special electronic circuitry is disclosed to detect these pulses and to distinguish them from the background noise.

摘要： A cable core is advanced longitudinally through an extruder head where a protective tubular plastic jacket is formed therearound. A sensing device coupled to a test set monitors jacket eccentricity along a pair of normal, coplanar cross-sectional axes, generating a pair of polarized analog signals which are coupled to a level detector which generates outputs indicating on which side of each axis the jacket is eccentric. The outputs of the level detector are coupled to a logic circuit, synchronized by a clock, which gates the outputs of first and second oscillators selectively to one of two inputs of first and second drive circuits associated with first and second reversible stepping motors. A first slide is mounted for rectilinear movement slidably within a second slide mounted for transverse rectilinear movement. The stepping motors selectively drive the slides to impart translational movement to the first slide, which is coupled to one end of a core tube pivotally mounted in the extruder head to position the other end of the core tube adjustably within a passageway formed in an extrusion die in the head, automatically to correct any measured jacket eccentricity. Alternatively, the stepping motors may be controlled manually through a lever-actuated switch to vary the relative position of the core tube and the die without the eccentricity signals. Additionally, third and fourth stepping motors may be driven in synchronism with the first and second stepping motors, respectively, to drive a cross hair display which indicates visually the position of the core tube with respect to the die.

摘要： An optical waveguide comprising either a substrate coated with a layer of optic material or a clad optic fiber. A periodic variation in the index of refraction of either: (1) the substrate and/or the optical layer, or (2) the core and/or cladding of the optic fiber, is introduced so that unwanted frequency components present in the optical signal passing through the waveguide are eliminated. The waveguide may be employed as a band-pass or a band-stop filter, or for phase-matching purposes. Various means are disclosed for altering the periodicity of the index of refraction to thereby tune the device.

摘要： A cable core advances through an extruder head and then past an ultrasonic test set. In the extruder head, an annular plastic jacket is formed about the core. The test set generates four signals which correspond in magnitude to the jacket thickness in orthogonally spaced quadrants of the jacket. The signals are then applied to apparatus for centering the core with respect to the extruder head. Additional apparatus generates control signals in response to the signals from the test set. The control signals are applied to a mechanism for adjusting the jacket thickness in diametrically opposite quadrants with respect to the thickness in the quadrants adjacent thereto to control the uniformity of the jacket thickness. The control signals are also applied to a mechanism for controlling the overall jacket thickness. The signals give priority to the function of controlling the uniformity of the jacket thickness before the overall jacket thickness is reduced to a predetermined thickness range. A special control signal overrides other signals for controlling the jacket thickness and causes an increase in the overall jacket thickness whenever the jacket thickness in any of the quadrants falls below a predetermined minimum thickness.

摘要： Apparatus for automatically forming wires on a wire-receiving member, such as in the manufacture of harness-type cable, includes a bank of wiring heads, one for each wire or set of wires, and through which the wires extend from respective tensioning devices and supply reels. The wiring heads are releasably mounted on respective seats and a wire positioning device is mounted for movement in X, Y and Z directions. At the start of a cable forming operation, end portions of the wires which extend through the wiring heads are anchored against movement. The wire positioning device, under the direction of a controller, then attaches itself to a selected one of the wiring heads, removes the wiring head from its seat, lays out wire through the wiring head on a cable forming board, including the securing of the wire to an anchor member on the cable forming board at the beginning and completion of the run, returns the wiring head to its seat, and detaches itself from the wiring head. This sequence of operations is repeated by the wire positioning device with the other wiring heads and their associated wires, selectively, until the layout of the cable has been completed.

摘要： A sorting apparatus transfers selected semiconductor devices from a first carrier, to which they have been cemented with an adhesive, to a second carrier to form a new array composed entirely of selected devices by: heating the first carrier just enough to soften the adhesive, heating the selected devices and small adjacent area with a hot air gun to a high enough temperature to melt the adhesive and release the device, and transferring the device to a second carrier. This avoids deleterious changes in the adhesive which arise from prolonged heating at the elevated melting temperature and which make it difficult to remove any remanent adhesive which clings to the devices. When the second carrier is dark, such as a barium ferrite magnet is, an array of light colored squares, one for each device, is formed on the carrier. Since each square is obscured when a device is transferred to it, or is distinctly visible when transfer does not occur, an immediate indication of the completeness of the array is provided with only cursory inspection.
摘要翻译：分拣装置将选定的半导体器件从其已经用粘合剂粘合的第一载体传送到第二载体，以形成完全由选定器件组成的新阵列，其方法是：加热第一载体足够软化粘合剂，加热所选择的装置和具有热风枪的小邻近区域到足够高的温度以熔化粘合剂并释放装置，并将装置转移到第二载体。这避免了由于在升高的熔融温度下的长时间加热而产生的粘合剂的有害变化，并且这使得难以除去附着于器件的任何残留粘合剂。当第二载体较暗时，例如钡铁氧体磁体，在载体上形成一个浅色正方形，每个装置一个。由于每个方块在设备转移到其上时都会被遮挡，或者在不发生传输时是明显可见的，所以仅提供粗略的检查即可提供阵列的完整性。

摘要： A transformer in combination with a push-pull transistor switch forms the inverter of a DC to DC converter. Feedback from the rectified output of the transformer ferroresonant winding controls the inverter frequency. A controllable current source solely responsive to a signal derived from the converter output voltage controls the charging of a timing capacitor which upon reaching a threshold value causes termination of each inverter half-cycle. The current source includes a clamping device operative to limit the inverter frequency to a region where effective negative feedback regulation is maintained.

摘要： In the manufacture of a tubular member which is to be concave inward as viewed in longitudinal section and precisely symmetrical on opposite sides of its transverse centerline, such as a hi-pass millimeter waveguide filter, a tubular billet initially is fabricated with temporary end flanges having circumferential grooves for receiving hydrostatic seals during a stress-forming operation. Next, the tubular billet is positioned in a hydrostatic forming device and a split mandrel is positioned within the billet and retained against movement. Hydrostatic pressure then is applied to the tubular billet to stress the billet longitudinally in tension while compressively stressing the billet inward into formed engagement with the mandrel, to reduce the hydrostatic pressure required in the stress-forming operation and to achieve the desired symmetry in the formed billet. The hydrostatic stress-forming of the billet preferably is accomplished in successive steps, with intermediate annealing, using mandrels of progressively decreasing size, and the billet may be stretched longitudinally while being formed inward. When the hydrostatic stress-forming of the billet has been completed, portions of the temporary end flanges which define the seal receiving grooves are removed from each end flange and the end flanges are formed to a final desired configuration.
