摘要： The casing (12A) of a hand-held instrument (12) provides a contact surface for a capacitive switching circuit (33A) for energizing a controlled device (63). The switching circuit and device are remote from the contact area. The switching circuit (33A) includes an input circuit (80) incorporating the body capacitance and a variable capacitor (81) which is adjusted to balance the circuit in the presence of only stray capacitance without body capacitance so that the switching circuit remains unactuated. The addition of body capacitance will actuate the switching circuit. In the illustrated embodiment, the input circuit (80) is energized by a periodic signal. An output signal is coupled from the switching circuit to the controlled device through a delay off circuit (88) which has a delay time longer than the period of the periodic signal so that if contact with the instrument is lost momentarily, there is no interruption in the controlled function. This is particularly advantageous in the case of a medical device or dental handpiece where light from a high intensity source is coupled back to the instrument for illuminating the work area.
摘要翻译：手持式仪器（12）的壳体（12A）为电容式开关电路（33A）提供用于激励受控装置（63）的接触面。开关电路和器件远离接触区域。开关电路（33A）包括具有体电容的输入电路（80）和可变电容器（81），该可变电容器（81）被调整为仅在没有体电容的杂散电容的存在下平衡电路，使得开关电路保持不激活。增加体电容将致动开关电路。在所示实施例中，输入电路（80）由周期性信号激励。输出信号通过延迟关断电路（88）从开关电路耦合到受控装置，该延迟关断电路具有比周期信号的周期更长的延迟时间，因此如果与仪器的接触瞬间失去，则不会中断受控功能。这在医疗装置或牙科手机的情况下是特别有利的，其中来自高强度源的光被耦合回到用于照亮工作区域的仪器。

摘要： Multipolar electrosurgical device (22) for use in neurosurgery or through the channel of an endoscope or other precision surgery procedures. The device is formed with an insulative probe body (40), which, in the described embodiment, is sized to pass through a channel of an endoscope to enable the electrocoagulation of blood vessels such as may be needed in the treatment of a gastrointestinal ulcer. The probe body is provided with electrically separate conductors (46, 48) which are formed of a plurality of electrodes (46.1, 46.2, 46.3, 48. 1, 48.2, 48.3) distributed over the peripheral surface of the probe body. A plurality of at least six electrodes which can form six bipolar electric fields are formed which in one embodiment are aligned longitudinally on the probe body. The electrodes extend onto the probe body's distal end to provide an omnidirectionally effective electrosurgical device. A central conductive wash channel (57) is provided for electrical connection to a set of electrodes at the distal end of the probe body while also providing a passage for fluid to enhance the visibility of the target area for subsequent precise electrocoagulation of the device. Several embodiments are shown and described.

摘要： A dental handpiece (10) having an improved water/air spray system including a pair of substantially parallel tubes (22, 23), one for water and the other for chip air, extending through the handle (11) of the handpiece and terminating in a nozzle chamber (21) of oval cross section. The tubes (22, 23) are generally cylindrical but are partially deformed at their distal ends, such deformation constituting a flattening of adjacent wall portions (22a, 22b) of the respective tubes. Such adjacent wall portions are disposed in contiguous relation and are cut away for a limited distance at the discharge end of the tube assembly to define the unitary nozzle chamber (21). The chamber has an oval discharge orifice (21a) for directing an elliptical spray pattern towards the tip of the dental bur. At the opposite end of the handpiece (10), the handle (11) is equipped with a plug (13) terminating in an external end face (17). Tubular extensions (15b, 23c) project from that end face for conveying air to the drive air and chip air passages (15, 23). An open channel (30) formed in the end face (17) of the plug (13) communicates with annular recesses (26, 27) disposed about such extensions, and each extension is provided with a lateral aperture (28, 29) communicating with the surrounding recess. The open side of the channel (30) and the ends of the recesses (26, 27) are sealed by a sealing member (32) when the handpiece is in operation.

摘要： A decanting centrifuge (10) particularly useful for clinical laboratory procedures requiring the washing and packing of red cells or other particles. An electromagnet (18) having upper (28) and lower (29) planar pole faces rotates to drive a removable rotor head assembly (40) and, during the decant cycle, holds a plurality of magnetically attractable tube carriers (43) in substantially vertical positions against its planar pole faces (28, 29) so that supernatant liquid is centrifugally discharged from the open upper ends of the tubes (57). Each tube carrier (43) comprises a tube-holding member (50) and a contact member (51), both of which have their upper end portions pivotally suspended from a support ring (46) which is provided by the rotor assembly (40) and which is coaxial with the rotatable magnet (18). The planar surfaces of the contact members (64) engage the planar pole faces (28, 29) when the centrifuge (10) is at rest and also when the electromagnet (18) is energized and the rotor assembly (40) is rotated to decant the liquid contents of the centrifuge tubes (57). Each tube-holding member (50) has two outer side walls (50b) which meet along converging planes so that such walls (50b) will engage a centrifuge tube (57) along a pair of spaced parallel lines (63) during centrifuge operation, thereby permitting centrifuge tubes (57) of different selected outside dimensions to be supported within the open-topped cavity of such tube-holding member (50).

摘要： An improved method of securing a thin continuous layer of metallic silver upon a tooth structure, especially the dentin surface of that structure, to seal the surface and, where desired, to provide a highly receptive surface for an amalgam restoration. The method involves first coating the dentin surface with an aqueous solution of a silver salt to form a silver-protein complex, then photoreducing the silver of that complex to produce a black base layer of complexed metallic silver, and thereafter electrolessly plating a continuous silver sealing layer onto the base layer.

摘要： An improved positive-grip chuck assembly, particularly suitable for use with high-speed air-driven dental handpieces, in which a tubular chuck (22) has a radially-flexible bur-clamping section (22c) provided with an external shoulder (27), and the bore (23) in which the chuck (22) is received has an internal shoulder (21) engagable with the external shoulder (27) of the bur-clamping section (22c) of the chuck (22) to flex the bur-clamping section (22c) inwardly and to hold the same in a constricted condition for securely gripping the mid-portion of the shank of a dental bur (32). Piloting contact is made between the chuck (22) and bur (32) along circumferential zones (29, 30) spaced axially from the bur-clamping zone (41), and the rotor (15) surrounds and braces the chuck portion (22a) defining the lower pilot zone (40) to prevent distorting forces applied to the tip of the bur (32) from being propagated to the bur-clamping zone (41).

摘要： A surgeon's glove which is free of mold release powder of mineral origin. The glove is "talc free" and contains on a surface a lipo compound and a surfactant for such lipo compound. The glove is manufactured by a process which includes coating a glove form (6) with a coagulant containing the lipo compound and its surfactant in a dispersion which stay with the glove after it is stripped from the mold providing a mold release surface for such glove.

摘要： A device particularly suited for collecting and dispensing an arterial blood sample. A needle (1) is connected to a flexible transparent tube (5) that includes an air exit vent (7) with a nonwet filter (8) so air, but not blood, can exit the filter under arterial blood pressure. A clamp (10) on the tube (5) pinches off a segment of blood and longitudinally strips such blood segment from the tube (5). The tube (5) has an oxygen blocking coating (39) which is covered with a dry anticoagulant coating (40).

摘要： A method of determining triglycerides in biological fluids according to an enzymatic reaction. In the reaction, a biological fluid is added to an enzyme reagent comprising a lipase, glycerol dehydrogenase (GDH), pyridine nucleotide (PN), a buffer, a tetrazolium compound and diaphorase, whereby the triglycerides are enzymatically hydrolyzed, and the resulting glycerol is oxidized to form a reduced pyridine nucleotide (PN) which reacts with said tetrazolium compound in the presence of diaphorase to produce a colored formazan which is the reduced form of the tetrazolium, which color is measured at a wave length ranging from about 475 to about 525 nm. The lipase is an enzyme obtained from Chromobacterium viscosum. In the enzyme reagent, there is from about 5.0 to about 15.01. U./ml of the glycerol dehydrogenase (GDH) present.
