Patent GB-1167433-A (GB)
Title: Improvements in or relating to Process of Cold Forming Sheet Components under Hydraulic Pressure
IPC: B21D26/02
Filed: 1967-04-10
Abstract: 1,167,433. Stamping. ETS CL. JACQUEMARD. 10 April, 1967 [14 April, 1966], No. 16262/67. Heading B3Q. A press for cold forming sheet components A under hydraulic pressure comprises a die 26, 27, 28 at the upper end of a set of toggle links 5, a ram 9 mounted on the upper end of a second set of toggle links 11, and a cam 20 displaceable to compensate for changes in workpiece volume, the links 5, 11 being straight by the end of the stroke of the ram 9 when a further ram 2, controlled by the energy-source previously used to operate the links, effects high-pressure calibration of the workpiece. The links 5, 11 and the cam 20 are operated hydraulically, by cylinders 8, 17, 21. The die includes a lower section 28 attached to the ram 9, a divided upper section 26 suspended from a cylinder 18 and a bevel-ring 27 for closing the section 26. A table 4 for operating the ring 27 is carried by the links 5 and may also raise the plunger 9, by its top flange. At each side of the ram 9, on its support 10, is an abutment 23 for operating pistons in cylinders 22. A nut 16 in a fixed table 3 adjusts the links 11 and thus the stroke of the ram 9. Operation.-After filling the workpiece with a liquid, e.g. water, cylinder 8 is operated for raising table 4, to close the die-section 26, and for raising the ram by its top flange. When the top links 5 are in a straight, locking condition, pressure in cylinder 8 increases, and a valve directs oil to the cylinders 17, which filled as the ram was raised by the top links 5. The cylinders 17 now develop the forming pressure on the ram, and at this stage the abutments 23 engage the pistons in cylinders 22 for supplying the cylinder 21 and displacing the cam 20. A piston 19 operated by the cam, controls the volume of water in the workpiece during the forming operation. Abutment between the die sections 26, 28 terminates the ram-stroke when the links 11 are straight. The oil in cylinders 17 now communicates with a cylinder 24 to increase the fluid pressure in the blank, by means of a plunger 25. In a modification, cylinder 21 is operated by a pump which is regulated by a pickup controlled by the ram 9 over the final part of its stroke.

Title: A synchronising device for a pulse communication receiver
IPC: H04L7/00
Filed: 1963-04-25
Abstract: 1,044,972. Multiplex pulse code signalling. NIPPON ELECTRIC CO. Ltd. April 25, 1963 [April 25, 1962], No. 16314/63. Heading H4L. A pulse transmission system is provided with " flywheel " synchronization at the receiver so that interference of short duration has no effect. Means for searching for and locking on to the correct synchronizing signal also are provided. As shown in Fig. 1, an incoming P.C.M. time division multiplex signal is supplied via terminal 21 to an output terminal 29 and also to a bit frequency filter 41 for deriving bit synchronizing signals, a bit-frequency filter 31 in a signal monitoring circuit 23, and an error pulse deriving circuit 53 in a frame synchronizing circuit 26. The bit frequency component from filter 41 is supplied to a phase comparator 43 together with the output of an oscillator 42 controlling the demodulating circuits, and the output of the phase comparator via a control signal store 44 and variable reactance 45 controls the oscillator 42. The filter 31 supplies a discriminator-amplifier circuit 32, Fig. 2 (not shown), for producing a predetermined D.C. output if the extracted bit frequency is normal so that a relay 33 is normally operated and a contact (not shown) in the control signal store 44 is closed, this contact when open causing the store to memorize the phase information for a time T1 on the occurrence of a fault. The relay is arranged to release after a delay t 1  after detection of an interruption in the incoming signal and to operate after a delay t 2  after the signal returns to normal. The time T1 is made much longer than the releasing time t 1  and longer than the anticipated failure time so that bit synchronism is maintained during the period T1. The frame synchronizing device 26 comprises a circuit 51 supplied with " error " pulses e from a circuit 54 which block bit timing pulses supplied from the oscillator 42 when pulses of the two trains are coincident, the output of the circuit 51 controlling a channel distributor 52. Assuming there are n channels, the n/2<SP>th</SP> and the n<SP>th</SP> output from the distributor are supplied to the error pulse circuit 53 which supplies an " interim error pulse train " e<SP>1</SP> only when frame synchronism has collapsed. The pulse train e<SP>1</SP> is supplied to the circuit 54 which is controlled by a switch contact (not shown) of the relay 33 so that error pulses e are only derived after a delay T f  (frame synchronization waiting time) if pulses e<SP>1</SP> are still present. Each pulse e causes the distributor 52 to be shifted by one position for restoration of synchronism. A delay Tp is also introduced after detection of correct synchronization before normal operation is resumed.

Title: Fabric measuring machine
IPC: G01B5/04
Filed: 1931-06-05
Abstract: 387,358. Measuring fabrics etc.; zeroizing-mechanism. WALTER, R. H., 121, Kingsway, London, and RUSSELL, N. L., Rusrene, Wickham Court Road, West Wickham, Kent. June 5, 1931, Nos. 16441/31 and 3614/32. [Class 42 (ii).] In a measuring- machine the fabric is slit to mark the measured length and the pressure roller 83 is lowered thus freeing the fabric and allowing the indicator to return to zero when a lever 58 is depressed. One or more of the indicators are returned to zero by the shortest path. As shown, the shaft 19 is rotated through gearing 20, 21 one revolution for each unit length of fabric &c. measured by the drum 18. This shaft 19 carries a fractions dial 22 for the salesman and drives through gearing 23 another fractions dial 25 for the customer. The two units dials 28, 33 are connected by skew gearing 30, 31 and are driven by a ten-toothed wheel 37 and a single tooth 38 on the sleeve of the dial 22. The two tens dials 29, 34 are connected by skew gearing 35, 36 and are driven by a ten-toothed wheel 49 and a single tooth 48 on a shaft 45 geared one-to-one with the shaft 32. When the lever 58 is depressed to cut the fabric a finger 98 on the shaft 57 lowers the pressure roller 83 and through lever and links 60, 62, 61, 76, 78 rocks two shafts 63, 79. The shaft 63 moves the tooth 38 out of gear with the wheel 37 to allow the fractions dials to be zeroized by means of the spring-pulled lever 54 and a heart-shaped cam 52 secured to the gear 21. Should the cam 52 be in a dead-centre position, a finger 64 on the shaft 63 hits a pin 65 on the wheel and moves the cam from such position. The shaft 79 first removes a stop pawl 51 from a ten-toothed wheel 46 and the units dials 28, 33 are zeroized by a lever 67 and an eccentric pin 68 on a disc 69 on the shaft 45 the exact zero position being determined by a spring wire 71 and a notched disc 47 also on the shaft 45. The stop pawl 50 is then moved clear of the ten-toothed wheel 49 and a coil spring (not shown) rotates the shaft 27 back to a zero stop 116. Should the pin 68 stop in a dead-centre position it is displaced by a light spring 74 as soon as the shaft 45 is freed. Should the fabric run out, an arm 95 resting thereon drops and allows the pawl 93 to lock the measuring drum 18. The upward pressure of the roller 83 can be adjusted by means of a spring 96 and nut 100. When the roller 83 is depressed by means of the thumb lever 58 it is locked in its lower position by a catch 104 ; a finger 87 on its pivot 86 lifts a plate 89 carrying a pin 90 which lifts the lever 91 on the same shaft 92 as the pawl 93 and frees the measuring drum at the same time as the indicating mechanisms are freed. The catch 104 can be disengaged by a finger lever 109. A steel tape &c. 122 for measuring the width of the fabric &c. may be provided.

Patent GB-166028-A (GB)
IPC: G03F3/04
Abstract: 166,028. Klein, A. B. June 4, 1920. Colour photography.-A process for producing photographic negatives for colour. printing or other purposes, consists in dispersing a source of light into a spectrum.and illuminating the object for each negative by a selected portion of the spectrum, the selected portions being mutually exclusive, and in some cases exactly complementary. Errors due to the overlapping of the spectral transmissions of the dyes employed in the usual colour filters are thus avoided. In the apparatus shown, light from a source 1 passes through a condenser 2, a slit 3, a collimator 4, and a constant deviation or dispersion prism 5. The spectrum formed is received by a collimator 6, having an adjustable slit 7. The light passing the slit 7 is projected by a condensing lens 8 on the object 9 to be photographed. The prism 5 is preferably mounted on a rotary table with a micrometer adjustment 12, by adjusting which and the movable edge of the slit 1 any desired portion of the spectrum may be employed. Instead of the prism being rotatable, both edges of the slit 1 may be adjustable.
