摘要： A first current is applied to the joined emitter electrodes of a first and a second transistor to be split into a first and a second fractions related in the ratio hfen to 1, which fractions flow as their respective collector currents. (The common-emitter forward current gain of the first transistor is hfe.) A first and a second paths extend from a common connection to respective base electrodes of the first and second transistors. Each path includes n junction diode(s) connected in series with the baseemitter junction of the transistor to which the path connects. A second current related to the first is applied to the second path to apply additional forward bias to the n diode(s) therein.

摘要： A receptacle adapted for insertion within electrical windings to secure a sensing element includes a sheet-like flexible material adapted to be centrally folded for providing first and second laterally extending portions. The first portion includes a tab having a pair of spaced openings each adapted to receive the sensing element and includes an outer portion adapted to be folded upon an intermediate portion while the intermediate portion is adapted to be folded and positioned opposite to the second portion with the outer portion positioned opposite to an inner portion so that the pair of spaced openings are aligned to receive the sensing element. The second portion includes a tab which secures the receptable positioned sensing element through the envelopment of a sensing element male terminal by one of a plurality of tab openings with the envelopment further secured through the connection of an external electrical lead having a female terminal to the sensing element male terminal. An alternative embodiment provides a latching tab which extends from the first portion and passes through one of the spaced openings and provides an outer laterally offset extension having an opening for receiving and securing the outer end of the sensing element.

摘要： The invention relates to a water heating system in which a single water heater is utilized in combination with a storage tank and pump to provide hot water for various uses. The invention is particularly directed to the use of a thermostatic mixing valve set at a predetermined temperature and located at a juncture between a recirculating conduit from the water heater and the conduit for the flow of water from the storage tank or a source of fresh water supply to the water heater so that water which has already been heated by the water heater may be mixed with the colder water supplied to the water heater to be heated.

摘要： A METAL PIPE IS SUSPENDED FROM A TOWER BY A HANGER STEM FOR BEING OPERATED ON WITH A QUENCHING PROCESS. AFTER FIRST BEIG HEATED, THE PIPE IS LOWERED TO A QUENCHING ASSEMBLY WHERE ROTATING STREAMS OF CONCENTRATED, HIGH PRESSURE QUENCH FLUID IS APPLIED TO BOTH SURFACES OF THE PIPE SIMULTANEOUSLY. THE ROTATING STREAMS ARE PROVIDED BY CONCENTRIC INNER AND OUTER ROTARY QUENCH HEADS, BETWEEN WHICH THE PIPE TELECSCOPES. THE INNER HEAD IS OPERABLY SUPPORTED IN A WELL BY AN INNER STEM, WHICH HAS A SHELL BENEATH THE QUENCH HEAD.THE SHELL IS ENGAGED BY A GUIDE ARM ASSEMBLY TO CENTER THE STEM AND INNER QUENCH HEAD WITHIN THE WELL. WHEN THE PIPE IS LOWERED TO THE LEVEL OF THE GUIDE ASSEMBLY, THE GUIDE ASSEMBLY DISENGAGES THE SHELL AND GUIDES THE PIPE TO CENTER IT BETWEEN THE QUENCH HEADS.

摘要： A monitoring system has a small signal amplifier to amplify the low millivolt signals of a remotely located flowmeter. A pair of transistors are mutually parallel connected in emitter follower configuration by a variable bias potentiometer to the meter through three terminals. Each transistor supplies an input to an analog comparator with resistive and capacitive feedback to provide common mode rejection with a single-ended output signal. An isolating transistor in common collector configuration is connected to the output of the analog comparator for impedance transformation. The transistors are selectively connected to receive either a pair of balanced incoming signals or an unbalanced signal. A reference signal is applied as an input to one of the parallel connected transistors in unbalanced operation.

摘要： The side member and crossmember of a vehicle frame are mounted in a fixture within a sealed welding chamber at a welding station and a plurality of electron welding guns are arranged along a weld line for simultaneous welding of the several components of the frame with the beams of the guns overlapping to provide an uninterrupted continuous weld. A loading station and an unloading station is mounted to the opposite sides of the welding station and connected thereto by a vacuum lock transfer station. The welded frame is coated with a protective metal such as aluminum or zinc by passing the welded frame through a metal vapordepositing chamber disposed immediately in-line following the welding chamber.

摘要： The present disclosure relates to tiedown means. A stack of vehicle frames are mounted on a bed. A box beam is disposed over the frames or integrated into the bed. A pair of parallel torsion shafts having a high spring rate are mounted in the box beam. The first shaft is fixed at one end to the beam end wall and protrudes from the opposite wall. A crank is secured to the free end of the first bar and disposed between a pair of stop elements on the end wall. The shaft is prestressed to engage the one stop with a selected stored energy with the holding rotation of the arm increasing the stress. The second shaft is similarly constructed, but oppositely disposed to dispose the crank to the opposite end of the assembly. Suitable straps or chains are interconnected to the cranks to clamp the load to the bed. A one-way locking means selectively limits the movement of the crank to prevent pivoting and increasing the shaft stress after the initial setting.

摘要： This disclosure includes a pair of drive motors energized to move a weld head along two related perpendicular axes in a horizontal plane. The one motor is a variable speed motor. A closed servoloop includes a reference input to establish a constant velocity drive along the related axis for the variable speed motor. A separate cam and follower positions a potentiometer to generate a signal proportional to the velocity correction at each point on the path for lateral movement with respect to the one axis. The signal is combined with the reference input in the servo to establish a modified drive signal. This maintains the resultant horizontal velocity vector constant.

摘要： This disclosure relates to gasoline dispensing including an intermediate grade pump interconnected to both the premium grade storage tank and the regular grade storage tank through a blending valve. The blending valve includes a pair of flow passageways. A common throttling valve inversely varies the flow through the two passageways. A manual control valve is provided to adjustably and inversely set the cross-sectional areas of the flow passageways. The throttle valve is connected to a hydraulic diaphragm actuator having pressure chambers to the opposite sides of a movable diaphragm. Signal pressure lines connect the passageways between the two valves to corresponding pressure chambers to position the diaphragm and throttling valve to establish equal pressures in the passageways.
