Abstract: 1407868 Cutting and mounting transparencies EASTMAN KODAK CO 18 Jan 1973 [19 Jan 1972] 2689/73 Heading G2X [Also in Division B4] Apparatus 15 for severing a portion 10 e.g. a film frame of an elongate strip 11, e.g. of exposed film, wherein the apparatus comprises a strip cutter 35 and a retaining member 21 for holding the strip portion on a strip support e.g. a mount 3, in preparation for the cutter to sever the strip portion from the remainder, the retaining member, in a retaining position being arranged to hold the strip portion on the support, and spring means connected to the retaining member and arranged to move between two actuating positions in which it urges the retaining member to the retaining position and a rest position respectively. The cutter comprises a blade 35 secured to a support member 36 which is pivotally mounted on a side wall 39 of a table 16, the blade being pivoted to an inoperative position by a spring 43. The retaining member is in the form of a lever pivotally mounted in a slidable carriage 18 between the rest postion A, Fig. 3, and the retaining position, the lever being moved to either of the positions by an over-centre spring device 28. The apparatus also includes a pair of rolls 50, 51, the roll 50 being loaded by spring 60 toward the roll 51, the rolls are rotated by gears 68, 69. In operation, with the apparatus in the position shown in Fig. 2, a plastics mount 2, 3 is located on the table 16 in front of the carriage 18 and the film strip fed across the mount portion 3 until the film frame 10 is located above a recess 9 in the frame. The blade support member 36 is then moved downwardly until a projection 44 thereon engages the lever 21 causing the over centre spring to move an arm 45 of the lever into contact with the film frame 10; continued movement of the member 36 then causes the blade to sever the strip. The blade is then allowed to return to its rest position and the carriage 18 moved forwardly taking with it the frame 23. As the position 2 of the frame approaches the rollers 50, 51, it is folded on to the frame portion 3 by a sloping plate 48 thereby causing pins 5 on the portion 3 to enter holes in the portion 2. Continued movement of the carriage 18 causes the folded frame to be gripped by the rolls and drawn therebetween Fig. 6 (not shown), the pins 5 then being peered over thereby; the frame is delivered by the rolls into a container 71. As the carriage is returned to its initial position, an arm 31 on the lever 21 engages a resilient pin 73 thereby causing the over-centre spring device to return the retaining member to its rest position.

IPC: A61B19/00
Filed: 1946-01-29
Abstract: 608,264. Dental &c. equipment stands. RITTER CO., Inc. Jan. 29, 1946, No. 2906. Convention date, March 14, 1945. [Class 81(ii)] A stand for supporting dental, medical, &c. equipment comprises a pedestal or support, an instrument holder movable between positions where the instruments are accessible for use, and are enclosed respectively, and switch-controlled motor means for moving the holder. As shown. the pedestal 31 carries a casing 33 provided with a sliding cover 63 and in which moves the instrument holder 42. This is formed as a rectangular block provided with sockets 45 accommodating say an air syringe 48, lamp 49, cautery 50 and water syringe 51, each instrument being connected by a flexible cord, &c. 52, passing round a pulley 132 to a spring reel 144. A carriage 53 reciprocates within the casing on flanges 54, and in turn is formed with guides 55 on which the holder 42 may reciprocate. Outward movement of the carriage brings its guide 55 into contact with a lip 58 on the holder to move the latter to the position of Fig. 11. When the carriage is retracted the holder is moved inwards by its weight and by springs 59. The carriage however, travels further inwards after the movement of the holder has stopped, this additional movement being utilized to close the casing cover 63. This is effected through pivoted links 80, 83 carrying a roller 82 which engages a pivoted arm 73 co-operating with an arm 71 attached to the cover. The latter is provided with rollers 68 running on tracks 67. The means for reciprocating the carriage 53 comprises double-threaded spindles 84, 85 rotatably mounted on the casing, the two threads being joined at each end of the spindles. Bevelled threadfbllowers 94 are carried by plugs 95 rotatably mounted on the carrier, so that if the spindles are rotated continuously, the carrier reciprocates. The spindles are rotated by a motor 105 and a chain and sprocket connection 103, the motor shaft being provided with a solenoid-operated braking device 108. The electric circuit comprises a manually operated switch, the operation of which closes the motor circuit. A second switch 117 in parallel and attached to the casing is adapted to be opened by cam surfaces 121, 122 attached to the carriage. When therefore the carriage has moved a short distance from one of the extreme positions on closing the manually operated switch, one of the cam surfaces 121, 122 disengages, closing the switch 117, and movement continues to the other extreme position, when the switch 117 is opened by the other cam surface and the movement is arrested. The circuit is also such as to apply the solenoid-operated brake 108 when the motor is inoperative. A modification of the device is described, in connection with which U.S.A. Specification 2,328,924 is referred to, in which the flexible current and fluid conductors, instead of being taken up on reel 144, hang in a loop in the base of the device passing around pulleys on a vertically-slidable carriage.

Abstract: 1,176,861. Automatic voltage control. ROBERT BOSCH G.m.b.H. Jan. 20, 1967 [Jan. 21, 1966], No.3112/67. Heading G3R. An electrical supply system, e.g. for a motor vehicle, comprises an alternator 10 which is connected over a rectifier 12 and output leads 13, 14 to a battery 15 and a load 17; controllable rectifiers 22, 23 connected in series with the generator field winding 18 so that the latter can be supplied with pulsating excitation current derived from the A. C. output of the alternator; a first voltage divider 36, 37 having its tapping point 35 connected over a diode 38 and respective balancing resistors 39, 40 to the control electrodes of the rectifiers 22, 23; and a transistor 19 having its collector-emitter path connected in parallel with the resistor 37 and having its base connected over a Zener diode 27 to the tapping point 29 of a second voltage divider 32, 33, 34 connected across the output leads 13, 14. In operation, so long as the output voltage is below a predetermined value both Zener diode 27 and transistor 19 are non- conductive, and the rectifiers 22, 23 are rendered conductive by virtue of the positive potential at the tap 35 so that excitation current flows in the field 18. At the predetermined value of output voltage Zener diode 27 conducts to render transistor 19 conductive, whereby the potential at tap 35 becomes negative, so that the rectifiers 22, 23 cannot fire; thus the average value of the field current is controlled in a manner such that the output voltage is maintained constant at the predetermined value. A further transistor 45 is rendered conductive, should the excitation current become excessive for any reason, to short-circuit the control electrodes of rectifiers 22, 23 and thus prevent their firing, whereby the alternator 10 and the rectifiers 22, 23 are protected against overload.

Abstract: 1481665 Transistor D.C. amplifiers; pulse-width modulators SPERRY RAND CORP 24 Jan 1975 [28 Jan 1974] 3124/75 Headings H3T and H4L An apparatus described as a solid state potentiometer for coupling a D.C. voltage of variable amplitude from a function generator 11 to an apparatus 24 with electrical isolation therebetween, comprises an oscillator 15 of constant frequency feeding a pulse width modulator 13 also connected to the function generator, producing a signal of the same frequency and with duty cycle proportional to the said D.C. voltage, non-electrical isolation means 20 coupling the signal to a second modulator 21 for reproducing the signal referenced to a D.C. reference voltage produced by a D.C. voltage source, and a converter 22, 23 for converting the signal to a D.C. voltage output of amplitude proportional to the voltage input from the function generator 11, the output internal resistance varying with output voltage in a similar way to a conventional potentiometer. A 5 kHz unijunction transistor oscillator 15 includes a capacitor (53), Fig. 26 (not shown), which is charged through an FET (51), and discharged by the unijunction transistor (54), a bipolar transistor (52) shunting the capacitor (53) and ensuring complete discharge. Pulse width modulator.-In the pulse width modulator 13 a sawtooth waveform from oscillator 15 is fed to the base of a transistor 34, Fig. 2a. The output of 13 which is taken from the collector of a transistor 36 in a feedback circuit 14 is a square wave having the frequency of the oscillator 15 and with the duration # of the positive portions of each cycle proportional to the D.C. input signal. The feedback circuit 14 includes a capacitor 47 the voltage on which is proportional to #, and this voltage is coupled to the non-inverting terminal of an amplifier 25 in a Miller integrator 12 where it is subtracted from the D.C. input signal, the resulting error signal being coupled back through a capacitor 26 to the inverting terminal of the amplifier 25. The output of the integrator 12 then changes to reduce the error signal to zero. The pulse width modulated signal feeds an LED (84), Fig. 2c (not shown), in the isolator 20, pulses of light being produced proportional in length to the positive portions # of the waveform, which are received by a photodetector diode (85). A transistor (92) in chopper circuit 21 reproduces a pulse width modulated signal, referenced to potentials at terminals (A, B) supplied by a separate D.C. source 16 optionally driven by the oscillator 15. A capacitor (91) reduces the turn-on time of transistor (92). A low pass filter 22 and Miller integrator in a buffer stage 23 produce a D.C. output voltage KV REF proportional to the input and referenced to potentials, V REF USER and LOW, supplied by the output apparatus 24.
