Title: Improvements in and relating to multi-stable state circuit arrangements such as shift registers
IPC: G11C19/20
Filed: 1964-01-21
Abstract: 986,747. Shift registers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 21, 1964 [Jan. 24, 1963], No. 2619/64. Heading G4C. [Also in Division H3] A multistable state circuit or shift register comprises a plurality of series circuits connected in parallel across a power supply, each series circuit comprising a resistor R1, a gas filled tube D1 and the parallel combination of a capacitor C1 and a diode G1. Each series circuit is coupled to the next via a resistor R1n and a diode G1n. Shift pulses on line P are fed to each stage via capacitors such as C1n. Data may be fed in to the first stage at the termination of each shift pulse on line P, neon tube D1 being ignited or not in accordance with the data, the pattern being stepped from left to right by the shift pulses on line P. Alternatively data may be fed in parallel by means of diodes (not shown) connected to the cathodes of the neon tubes. Assuming neon tube D1 is ignited and D2 estinguished, the leading edge of a -150 V shift pulse at P reduces the potential at the junction of R1n and G1n so as to extinguish tube D1 and charge C2 negatively via diode G1n so as to ignite tube D2. Capacitor C2 is then discharged by tube D2 and held discharged by diode G2. It is explained how patterns such as that in which successive tubes are conductive, may be shifted by one stage on the arrival of a shift pulse at P.

Abstract: 1536931 Endless conveyers NTN TOYO BEARING CO Ltd 23 Jan 1976 [28 Jan 1975 13 Nov 1975 14 Nov 1975 15 Nov 1975 18 Nov 1975 26 Nov 1975] 02650/76 Heading B8A Apparatus for use in transferring apertured workpieces W comprises a conveyer frame 4 in which an endless chain 2 is mounted for movement under the action of a drive motor 1 connected to a sprocket 5, the chain 2 being provided with spaced laterally-projecting pins 3 which extend through a slot in the frame 4 for supporting a respective workpiece for transfer exteriorly of the frame 4. Inlet feed means 6 and outlet means 7 are provided for feeding and removing workpieces to and from the pins 3 respectively, and a by-pass means 8 is provided for removing selected workpieces W at a position intermediate the means 6 and 7. The by-pass means 8 comprises detector dogs 13 attached at spaced positions along the chain 2, each such dog 13 being associated with a pin 3 carrying a selected workpiece W. The means 8 also comprises a slide 57 which is mounted on the frame 4 (Fig. 15) for reciprocable horizontal movement, the slide 57 having pivotally mounted thereon a catcher arm 59 which is biased upwardly towards the chain 2 by a spring 62 so that the upper end of a catcher 58 rotatably mounted thereon projects into the path of the detector dogs 13 on the chain 2. When a dog 13 engages the catcher 58 it pushes the catcher 58 and thus the slide 57 in the direction of conveyance. Attached to the bottom of the slide 57 is a cam follower 75 which is caused to engage a surface of a swing arm 72 which is thereby rotated about a vertical axis, the arm 72 being connected to an ejector plate (71), Fig. 16 (not shown), which is correspondingly rotated to engage the workpiece W on the pin 3 associated with that detector dog 13, thereby dropping the workpiece from that pin 3. A roller 64 on the catcher arm 59 then engages a cam 55 which causes depression of arm 59 and thus the catcher 58 is moved out of engagement with the dog 13. A spring 68 returns the slide 57 to its original position and the spring 62 urges the arm 59 and catcher 58 upwardly to await the arrival of the next detector dog 13. The inlet feed means 6 comprises a pair of spaced parallel conveyers (24, 24<SP>1</SP>) on which the workpieces are transported in single file to a vertical portion of the slot in the frame (4), each pin (3) as it passes along that slot portion passing upwardly between the conveyers (24, 24<SP>1</SP>) to engage and entrain a workpiece, Fig. 9 (not shown). Alternatively, the feed means may comprise a slotted platform (XXIV) mounted adjacent the vertical slot portion of the frame (4), each pin (3) as it passes through the slot (45) in the platform removing a workpiece therefrom.

Filed: 1962-01-24
Abstract: 980,643. Resilient mountings. F. BREMSHEY, and W. FULLING. Jan. 24, 1962 [Jan. 27, 1961], No. 2660/62. Headings A4J and A4U. A seat frame is arranged on an L-shaped lever 6, which is one link in a parallelogram linkage system and one arm 8 of which is engaged by a pair of links 14 which transmit damping load from a shock absorber. Adjustment of the effective lengths of the link 14 permits variation in the height of the seat and adjustment of the distance between the axis 3 about which the arm 8 is pivoted and the point of engagement 18, between the arm 8 and links 14 varies the damping load, these adjustments being independent. The arm 8 is provided with holes 9 which are engaged by studs 19 around the periphery of a prism 17 eccentrically pivoted between the links. The supporting surface of each stud is a different distance from the pivot 18 and hence determines the effective length of the links, whereas the holes 9 determine the distance between pivots 18 and 3.

Title: Facsimile recorder including an automatic gain control system
Inventor: MASON FREDERICK PERCIVAL
IPC: H04N1/407
Filed: 1955-01-28
Abstract: 763,820. Automatic volume control. CREED & CO., Ltd. Jan. 28, 1955, No. 2668/55. Class 40 (4). [Also in Group XL (b)] Phasing pulses preceding each scanning cycle in a facsimile system are employed automatically to set the recorder gain to a desired level where it remains fixed until reset by the next phasing signal. The incoming channel 1 is connected through amplifier 2 to two channels 3, 4, one of which includes a limiter 5 arranged to produce an output in response to phasing pulses corresponding to an amount deemed desirable for a picture signal to be applied to the recording system, and the other of which feeds the recording system through a variable attenuator 6. The two channels supply inputs to a comparitor 16 arranged to deliver a D.C. output to operate a relay CR when the input from limiter 5 is equal to a greater than that from attenuator 6. Attenuator 6 is controlled to decrease its attenuation by a motor 8 and to increase its attenuation by a motor 10. Either motor may be energized from source 15 by appropriate actuation of contacts MR2 of a relay MR. In the stand-by condition motor 8 is energized and the attenuation set to a minimum whereby the signal fed to comparitor 16 will exceed that from limiter 5. Upon reception of phrasing pulses, the first passes from limiter 5 to a detector 17 and operates relay MR which locks over contact MR1 and at contact MR2 energizes motor 10 in place of motor 8. The attenuation in channel 4 is now slowly increased, and when the input supplied to comparitor 16 ceases to be greater than that from limiter 5, relay CR operates, locks over contact CR1, and de-energizes motor 10 at contact CR2. The system then " freezes" with the signal delivered by attenuator 6 standardized and remains thus throughout the subsequent scanning cycle. At the end of the message, power is removed from the system to release relays MR and CR whereupon motor 8 restores attenuator 6 to minimum attenuation to await reception of the next following phasing signal. By means not shown, the operation of relay CR may be arranged to pass a " proceed to scan " signal to the transmitter.
