Title: Electromagnetic relays
IPC: H01H51/10
Filed: 1926-02-26
Abstract: 270,843. Tyer & Co., Ltd., and Punter, J. W. Feb. 26, 1926. Electromagnetic switches; switches, latching and unlatching; contact-making relays.-A relay for energizing an electromagnetic device such as the lock of a lever or tablet in railway working has an armature which has a restricted movement on the reception of a weak current and completes its movement on the reception of a succeeding stronger current. As shown in the Figure the electromagnet 2 when energized by a weak current attracts its armature 4 against the spring 5 so causing a contact 6 to engage a contact 12 carried by a lever 8 pivoted at 9. The engagement of contacts 6, 12 completes through contacts 16, 17 the energizing circuit of an electromagnet 20 which attracts its armature 21 so removing the hooked end 22 out of the path of the hooked end 23 of the arm 7 carrying the armature 4. When a succeeding stronger current passes through the electromagnet 2 the arm 8 is moved against the end of a pivoted arm 30 overcoming the resistance of springs 10 and 5 and of an adjustable spring 31 acting on the arm 30 and causing engagement of contacts 32, 33 to complete the energizing circuit of the electromagnetic device. During the intermediate position of the armature 4 a bell circuit is completed at contacts 25, 26. If the stronger current is not preceded by a weak current the contacts 16, 17 disengage before the latching electromagnet 21 can be moved and the bell contacts 25, 26 are arranged to remain in contact while the armature 4 is held against further movement. With currents of intermediate strength the spring 31 is sufficiently strong to prevent the complete movement of the levers 7 and 8 even if the armature 21 has been attracted.

Title: Method and apparatus for altering the synchronous compare character in a digital data communication system
IPC: H04L7/00
Filed: 1975-02-10
Abstract: 1486666 Data transmission; synchronizing BURROUGHS CORP 10 Feb 1975 [28 May 1974] 5555/75 Heading H4P A synchronizing character in a data transmission system is periodically changed to prevent unauthorized interception. The synch. characters are generated in a determined non-repetitive pattern then placed in a means storing at least one character for subsequent transmission at the head of a message. The synch. character need not necessarily be changed between each message depending on the degree of security required. At a receiver an identical sequence of synch. characters may be generated for comparison, or the next synch. character may be included in a data message or defined characters may be used at specified times. Until correct comparison with incoming synch. characters is achieved, a receiver will not be enabled to accept a message. In one embodiment, a separate random access memory is used for the storage of synch. characters but this is not essential as a random access memory of a main processor may be used. When receiving, a "sliding window" search of a received bit stream may be made to locate a synch. character which matches the appropriate stored one. In an arrangement described the method is used in a system whereby terminal computers operate through data sets and land lines to a central computer but other arrangements are envisaged. A schematic arrangement suitable for use with a processor is given in Fig. 3 (not shown).

Abstract: 922,237. Vehicles with detachable bodies. DEMPSTER BROTHERS Inc. Feb. 18, 1960 [March 18, 1959], No. 5748/60. Class 78 (4). A detachable vehicle body 46, Fig. 16, is loaded on to the vehicle by being pulled up, tilting frame members 5, pivoted to the chassis at 10, by an hydraulically-operated bail 32. As described, the bail 32 is pivoted to a carriage 24, Fig. 10, at 37 and urged upwardly by a leaf-spring 43. Rollers 29 guide the carriage within channel members attached to the tilting frame members 5. To load the vehicle body, the operator engages the bail 32 with one of hook members 57<SP>1</SP>, Fig. 6, at the front of a frame 47, 50 on which the body is constructed. As the body is drawn upwardly in a series of steps by the hydraulically-operated bail 32 which successively engages hooks 55, detents 66 are engaged by a spring 67 to prevent the body sliding back as the bail is moved downwards towards the next hook. Each hook 55 has a shutter 58 so that the operator can engage the bail in either the forwardly or backwardly facing portion of the hook, thus enabling the body to be either loaded or unloaded. The spring 67 may be pivoted to an inoperative position. The body is locked in position when loaded by lugs 62, 64, Fig. 2, which engage plates on the body frame. A stabilizing jack having a ground-engaging roller 12 may be moved into operative position by an hydraulic or pneumatic ram 13 when the vehicle body is being loaded. The vehicle may have a jack on each side. So that the vehicle body does not become inadvertently detached from the bail 32 the front hook 57<SP>1</SP>   on the body cannot be covered by its shuttle 58. Specification 922,238 is referred to.

[Also in Divisions G1 and H3] In an electrical circuit for controlling the periods of time for which the electromagnetic fuel injection valves 21 of an internal combustion engine are opened in accordance with the degree of vacuum in the inlet manifold, the manifold pressure causes movement of the iron core of a transformer 41 so as to reduce the reluctance of the primary winding as the pressure decreases and hence reduce the relaxation time of a monostable multi-vibrator comprising transistors 35, 36 to reduce the period for which the valves 31 are energized via amplifiers 73, 32 each time the multi-vibrator is triggered by timing pulses from a cam-shaft switch 64 via a transistor 34. In order to change the proportionality between transformer core position and fuel valve timing, the output of the multi-vibrator 35, 36 is modified at 71 (four alternative circuits are disclosed, see Division H3) and fed back to the input so as to temporarily either aid or oppose the standing bias from a potential divider 51 so as to prolong or shorten the output pulse.
