Title: Receiver for pulse form light signals
IPC: H04B10/69
Filed: 1973-11-22
Abstract: 1423275 Pulse receiver ELTRO GmbH GES FUR STRAHLUNGSTECHNIK 22 Nov 1973 [16 Jan 1973] 54190/73 Heading H4D In a photo-electric receiver, for receiving light pulses, e.g. echoes of a laser pulse radar, having a very small mark to space ratio, the light pulses are received by a photodetector D (e.g. a diode) and the resulting signal amplified at V. Noise accompanying the pulse signals is reduced in a suppressor N by the suppression of all signals having an amplitude below a threshold U 1 . The remaining interference pulses are fed to first, slow time constant, control circuit K 1  where the average value of the signal is obtained in a store 51 (e.g. capacitive) and compared with a reference V 2 . Any difference U 4  would normally be used to control the sensitivity of the photo diode D and/or the sensitivity of the amplifier V until the amount of remaining interference is sufficiently reduced. Due however to the slow reaction of the control circuit, intermittent interference pulses are not removed, and to overcome this the use is proposed of a second fast time constant control circuit K 2  fed with the output of the amplifier and combining its output U 5  with that of U 4  of the first control circuit K 1  to give a final control signal U 6 .

Title: Improvements in straight bar knitting machines
Inventor: SADLER DERICK
IPC: D04B11/06
Filed: 1966-12-06
Abstract: 1,223,831. Knitting-machines. D. BYFORD & CO. Ltd. 6 March, 1968 [6 Dec., 1966], No. 54441/66. Heading D1C. In a straight bar machine having lace point bars, the extent of whose transfer and reset movements can be adjusted manually, means are provided for automatically adjusting the movements at the dictates of a punched tape. The bars are moved by lead screws racked by positioning cams, which can be adjusted for varying transfer and reset by chains 20 supported on sprockets 18-9 turned by levers 13-4. The levers may be set for moving the points one or two spaces in either direction, or may be set in a neutral position. The sprockets may also be turned via coupling 27-9 by pairs of solenoids 25-6 actuated by a punched tape. The transfer lever 14 may be set to transfer in either direction depending on the presence or absence of a hole in a tape track, and the reset lever 13 may be similarly set in the neutral position or reset in one direction. The extent of the adjustments is determined by stops limiting the solenoid stroke, which may also be pattern controlled. A delay switch operated when the main cam shaft is shogged, ensures that adjustments read by the tape do not actuate the solenoids until the following knitting cycle. In a modification each sprocket is adjustable by two pairs of solenoids so that they can be set to either of two extents in each direction, or if limit stops are used the extra pairs control additional displacements. In order to knit a cable the link rod (83, fig. 7, not shown) oscillating the rock bar may be may be held in its raised position by an arm (84) selectively engagable with projections (89, 90) on the rod. Loops of two end needles of a group of five are engaged by two points lifted, moved two needle spaces across the group and are reset one space. They are then lowered to pick up the third loop, moved two spaces where they remain while several courses are knit, then placed on the remaining two loops. The yarn is floated across one wale each side of the group.

Title: Improvements in or relating to Brake Control Means for Vehicles
Inventor: WALPOLE DAVID VALENTINE
IPC: B60T8/18
Filed: 1965-12-28
Abstract: 1,166,829. Load responsive brake control means. GIRLING Ltd. 18 Jan., 1967 [28 Dec., 1965], No. 54949/65. Heading F2F. A brake control means comprises a collapsible strut assembly actuated by a signal pressure and controlling a valve assembly which is subject to another pressure acting in the opposite sense, the strut-assembly transmits force up to a predetermined value of the signal pressure at which the strut assembly collapses and causes the rate of increase of the force transmitted to the valve assembly to be reduced relative to the increase of signal pressure The arrangement modifies the operating characteristics of the brake control means described in Specifications 917,494 and 1,037,630. When the driver's brake valve is operated signal air pressure acts on diaphragm 103, Fig. 1, and thrust member 102 until a predetermined pressure is reached, spring washers 101 then being compressed to allow the strut 37, 38 to collapse. Upon collapse spring 104 becomes effective to resist the air pressure acting on the thrust member. In modifications spring 101 is replaced by a coil spring or a rubber block or an annular rubber bush or a cantiler strut spring and spring 104 is replaced by spring washers or a plate disc spring or an annular rubber block in compression or shear or an annular air-bag. The diaphragm 103 may be omitted and thrust member 102 arranged as a sealed piston. In further modifications spring 104 is replaced by spring bellows in tension or compression and diaphragm 103 is replaced by a flexible inelastic diaphragm which may be arranged to co-operate with a sloping shoulder in order to decrease the effective diaphragm area with increased movement. In a further modification effective area of the diaphragm 123, Fig. 12, is reduced as increasing signal pressure causes an abutting sliding collar 124 to move along the thrust member against the loading of spring 125. In a further modification signal pressure initially acts on diaphragm 129, Fig. 13 which transmits force via an outer thrust member port to a spring 131 which collapses at a predetermined pressure. Diaphragm 129 engages a fixed abutment 132 and spring 131 then acts as a diaphragm of reduced effective area. In further modifications the diaphragm may be of rubber with spring arms or fingers and a stop may limit the travel of thrust member 102 after collapse. The various parts of the modifications are interchangeable.

Title: Magnetic locking mechanism
Inventor: SEDLEY BRUCE S
IPC: E05B47/00
Filed: 1970-11-27
Abstract: 1334085 Magnetic locks H O BOEHME CORP 27 Nov 1970 56529/70 Heading E2A A lock which is released by the insertion of a magnetically patterned key also has a pair of electromagnets 98, 100 to demagnetise part of the key on the lock being released to prevent its re-use without re-magnetisation. The lock comprises a block 22 having transverse apertures 32, 36 carrying sliding polarised magnetic tumblers 34, 38, which, in the rest position, stand in recesses 46, 48 in a fixed plate 26. The magnetic key pattern required to raise the necessary tumblers is preset by the insertion above them of a coded program card 56 provided with magnetised spots 58 which attract and lift some of the tumblers from their recesses 46. When the correctly magnetised key 94 is inserted, the remaining tumblers are repelled upwardly out of the recesses thus allowing further inward movement of the key to abut a projection 93 on the block 22 and move it rearwardly to cause a post 64 on the block to activate switches 82, 84. This in turn energises the bolt withdrawal circuit (not shown) and also the demagnetising electromagnets 98, 100. These act only on two areas 102, 104 at the end of the card which raise the last tumblers 38 from recesses 48, the others, 105, being unaffected. But their effect is to reduce or reverse the field of these areas so that they cannot push up these tumblers again. The used card may be correctly remagnetised, for reuse, in a magnetising unit which consists of nothing more than another identical lock in which the program card 56 has been turned over to reverse the polarities of the tumblers 34 so that they may be repelled upwards by the key card which has also been turned over. This unlocks the lock, and pushing the key into it moves the block to energise the electromagnets 98, 100, this time in a sense to revalidate the key for normal use. If an unauthorised key is inserted, a switch 80, Fig. 6, also operated by pin 64 detects the slight (but not unlocking) movement of the block, allowed by the clearance of pins 34, 38 in recesses 46, 48, to give the alarm after a short delay, which is, however, interrupted by operation of switches 82, 84 by the correct key (see circuit Fig. 14, not shown). A modified block without the pin 38 over spot 102 may be used to facilitate reversal (Figs. 12, 13 not shown). An additional anti-tampering circuit is also described (Fig. 15, not shown). (For Figures see next page)

Abstract: 1,185,133. Linkwork. CARL ZEISS JENA VEB. 29 Nov., 1968, No. 56753/68. Heading F2K. [Also in Division G1] A pointer or pen 11 of a measuring instrument is moved by opposed cables 1, 2 connected at their other ends to a drive member 3, each cable passing round at least one tensioning and guiding pulley 7, 9 mounted on a lever 15, 16, the levers being coupled together by a connecting rod 21. To compensate for changes in cable length due to humidity or temperature changes or ageing, without affecting the pointer or pen setting, the coupling of the levers ensures that the magnitudes of the tensioning movements of pulleys 7, 9 are proportional to the lengths of the cables 1, 2 which they engage. The drive member 3 may be a rotatable pulley, as shown, or a linearly movable member. As shown, a tensioning spring 19 acts on the lever 15. The connecting rod 21 is pivoted to the levers 15, 16 at distances h 1 , h 2  from their respective fulcra 17, 18 such that the ratio h 1 : h 2  equals the ratio of the length of cable 2 to the length of cable 1. The pulleys 7, 9 are at equal distances from their lever fulcra 17, 19. In a modification (Fig. 2, not shown) the connecting rod (41) is pivoted to the levers (33, 38) at equal distances from their fulcra (32, 37) and the distances of the pulleys (30, 31) from the fulcra (32, 37) of their respective levers are proportional to the lengths of the cables (25, 26) which they engage.
