Title: Improvements in and relating to control mechanism for screw presses
Inventor: PALMER JAMES MORRIS
IPC: F16P3/00
Filed: 1957-12-13
Abstract: 865,049. Machinery guards. BRITISH CERAMIC RESEARCH ASSOCIATION. Dec. 15, 1958 [Dec. 13, 1957], No. 38928/57. Class 80 (4). A guard (not shown) for a screw press for clay tiles &c. is connected through linkage L to a vertical spindle 10, a bracket 13 on which carries brake shoes 19, 20 or a stop which obstructs downward movement of the press-flywheel 21 (Fig. 4 position) until downward movement of the guard to the safe position turns the spindle 10 and brake-bracket 13 through 90 degrees to rotate the brake shoes 19, 20 out of the path of the flywheel and permit the working stroke of the press. During such stroke the flywheel rim 21 moves over a roller 17 on the bracket 13 and prevents return movement of the bracket 13 and hence movement of the guard from safe position. Towards the end of its descent, Fig. 8, the flywheel acts on the roller end 25 of a lever 24 to lift the bracket 13, whereupon a pin 12 carried in one of a series of holes (for adjustment) in the spindle 10 moves out of a locking recess 14a on the bracket 13 and to the bottom of a widened cam opening 14 therein, thus permitting the spindle 10 to be turned back through 90 degrees and hence allowing the guard to be lifted whilst the press is at the bottom of its stroke. During the return upward stroke of the press, the pin 12 occupies the lower apex of the cam face 14 and turning movement of the bracket 13 is prevented by the flywheel rim 21 until the latter rises above the bracket whereupon the latter falls by gravity, the cam face 14 riding over the pin 12, causing the bracket to be turned back to the obstructing position ready for the next cycle. With the brake shoe arrangement shown, the bracket 13, if in the guard-open obstructing position, is also slightly turned by the flywheel, whereby the vertical part 20 of the shoe contacts and brakes the periphery of the flywheel 21. Specification 859,390 is referred to.

Title: Communication system
IPC: H04B7/04
Filed: 1965-09-13
Abstract: 1,087,188. Automatic frequency control system; radio signalling. NIPPON ELECTRIC CO. Ltd. Sept. 13, 1965 [Sept. 11, 1964], No. 39016/65. Headings H3A and H4L. In a radio-communication system comprising a number of ground stations and a moving common repeater station, such as a communications satellite, each ground station is assigned at least two specific pilot frequencies, in predetermined relationship to a common datum frequency. One ground station is designated as a " master " station and its pilots are received by each of the other " slave " stations, after re-transmission and frequency shifting by the repeater station, and an equivalent datum frequency is derived, which differs from the original value because of Doppler effects in the paths from master to repeater and from repeater to slave. A similar equivalent datum frequency is derived from the returned signals from a slave station's own pilots which is compared with that derived from the master station's pilots, when automatic adjustment of the slave station's transmission is made until the two equivalent datum frequencies are substantially the same. In this way, the signals received by the repeater station from all ground stations are re-transmitted by it in substantially correct relative frequency relationship, in spite of differing Doppler shifts. As described, a receiving aerial 22B at a slave station feeds an amplifier 23B, a frequency converter 24B and an I.F. amplifier 26B, from which the master pilot signals are extracted by filters 27B, 28B and the station's own pilot signals by filters 33B, 34B. The equivalent datum frequencies are derived by frequency converters 29B, 35B whose outputs are applied to a phase comparator 36B which controls an oscillator 13B feeding a frequency synthesizer 14B. From the frequency synthesizer are obtained the pilot and carrier frequencies for the slave station's transmitter and a feed is also taken to a phase detector 32B, where comparison is made with the output from the frequency converter 35B. The phase detector 32B controls a receiving local oscillator 25B associated with the frequency converter 24B, so providing automatic frequency control for reception. The master station, Fig. 8 (not shown), is similar to the slave station, with the omission of one set of pilot filters, their associated frequency converter, and the phase comparator for the two equivalent datum frequencies.

Title: Improvements in voltage clamps
Inventor: CORNEY JOHN VICTOR JAMES
IPC: H04N5/18
Filed: 1963-10-08
Abstract: 1,027,249. Transistor circuits; television. THORN ELECTRONICS Ltd. Oct. 8, 1963, No. 39684/63. Headings H3T and H4F. The output voltage of a D.C. amplifier having a series input capacitor is periodically clamped by rendering periodically active a negative feedback path which charges or discharges the capacitor through a constant current device at a rate dependent upon the difference between the amplifier output voltage and a reference voltage. Television signals are applied through input capacitor C1 to an amplifier comprising transistors VT6-VT9 and having negative feedback between the emitter of the output transistor VT9 and the base of VT8. During the back porch period an input pulse at the base of VT5 causes VT1, the common emitter load of comparator transistors VT2, VT3, to become conductive so that the output voltage of the amplifier is compared with the reference voltage applied to the base of VT2. The latter transistor is coupled to the base of a transistor VT4 forming with VT3 a constant current charge and discharge path for the capacitor which resets the D.C. input level and thus the output level. During the restoration period the amplifier is thus provided with a negative feedback path which effectively reduces the input impedance of the amplifier to a low value so that the capacitor voltage will be quickly reset. Diode MR prevents VT3 passing current when the restoration circuit is not in use and diode MR2 prevents forward conduction between collector and base of VT7 if the base is driven negative. Large positive input signals will cause VT6 to cut off and VT7 to bottom so that the signals will be amplitude limited.

Title: Particle flow sensors
IPC: H03K17/94
Filed: 1975-10-04
Abstract: 1506651 Detecting particles photo-electrically DICKEY-JOHN CORP 4 Oct 1975 40716/75 Heading G 1A A particle sensor comprises two housing members defining a passageway which is lined with transparent wall portions positioned so that they will be wiped by particles as they fall through; and a light source and light responsive means for providing a pulse signal when a particle passes, the transparent wall portions overlying the source and responsive means. Seed released from a planting machine hopper, Fig. 1 (not shown) fall through a sensor, Fig. 3, comprising complementary housing portions 50, 51 defining a passageway, of which opposing wall portions are coated with a clear expoxy resin 62, 63 Fig. 4 which resists the accumulation of electric charge that might attract dust. Elimination of dust is further assisted by the shaping of the resin portions 62, 63 to facilitate the wiping of them by the passage of seeds. A LED 23a mounted on a circuit board 70 illuminates a window area of the coating 62; and phototransistors 27a (and 28a not visible) mounted on a board 84 behind a window area of the coating 63 emit a pulse every time a seed passes the window area. The phototransistors 27, 28, Fig. 2, whose current decreases when a seed is sensed, supply a negative pulse to a capacitor 41, the pulse being inverted by a transistor 40 and shaped by a small capacitor 46 to produce an output current pulse of the collector of a transistor 44. The normally-illuminated quiescent current of the phototransistors 27, 28 is amplified at 36, any superimposed pulses being smoothed out by a capacitor 32, and used to regulate the supply to the LED 23, to stabilize the illumination in the passageway against residual dust on the windows. The major portion 22 of the circuit is mounted on the board 84, to protect it from the heat generated by the current limiting resistor 24, which is mounted on the board 70 in series with the LED 23. In another embodiment, Figs. 6, 7 and 8 (not shown), the epoxy window portions are constituted by a tubular insert (113) retained in recesses in the housing portions (102, 103).
