Title: Improvements in automatic central buffer couplings for rail vehicles
Inventor: NOWIKOW IWAN
IPC: B61G5/06
Filed: 1968-12-18
Abstract: 1,248,238. Service line couplings of rail vehicles. GERMANY, MINISTRY OF TRANSPORT. 18 Dec., 1968, No. 60091/68. Addition to 1,233,566. Heading B7T. The parent invention is improved or modified by providing a bar 43 pivoted to a pivoted lock support 41 and engageable with an inclined surface 46 of a projection 45 of the service line coupling 1, so that the service line coupling 1 not only is held forward against the stops on the head 3 by the spring 17 but also is prevented from moving backwards, when the head 3 is in the uncoupled state, in order to improve the efficiency of coupling; on coupling, the countercoupling head moves the lock support 41 back into the head 3 and the bar 43 no longer prevents retraction, and hence coupling of the service line coupling 1 with that of the countercoupling can take place.

Patent GB-663891-A (GB)
Abstract: 663,891. Locking levers. BENDIX AVIATION CORPORATION. May 16,1949 [Sept. 30, 1948] No. 12990/49. Class 80 (iii) [Also in Groups XXV, XXXIII, and XXXV] A stick controller for an automatic pilot system for mobile craft comprises a normally vertical control stick 35 (Fig. 1) having a ball 36 at the lower' end mounted for universal oscillation in a bearing surface, a stop member 45 for limiting the movement of the control stick in the bearing surface, a brake 55 (Figs. 1 and 4) to retain the stick 35 in the position to which it has been moved, and an iris arrangement 49 encompassing the stick for returning it to its vertical position from the position to which it had been moved. At the upper end of the stick 35 is a knob 23 formed with a button 28 which when depressed opens a switch 31, 32. The stick supports a plate 19 and bellows 17 so as to seal off the iris arrangement and the housing 11 for the ball 36 from dirt. As shown in Fig. 2 the stop member 45 is provided with a squareformed opening 46 and the control stick is centered by rotating a lever 47 in a clockwise direction thereby bringing the iris members 49 to the dotted position shown. The lever 47 is spring biased to the full line position on release. Movement of the control switch about a pitch or bank axis operates a pitch or bank transmitter 72, 73 housed in a casing 61 depending from the housing 11 and sealed therefrom by rubber gaskets 65 and 71 and bellows 63 and 64. As shown in Fig. 4 movement of the stick about the bank axis rotates a rod 77 and causes oscillation of a lever 81 pivoted at 82. Oscillation of the lever 81 causes rotation of a lever 86 pivoted at 87 and consequent adjustment of the bank transmitter 73. A switch 121, having normally closed contacts 122 is opened by movement of the control stick from the neutral position. This switch is connected with switch 31, 32 and serves to disconnect the automatic pilot system during the manual control. For adjustment of the pitch transmitter, a slot 75 in the ball 36 is provided with an eccentric pin 95 (Fig. 5) and a cooperating lever 96 so that movement of the stick about this axis causes rotation of a rod 102 through lever 96, connection 99 and lever 97. Rotation of the rod 102 causes oscillation of a lever 108 about a pivot 109 thereby causing rotation of a lever 113 pivoted at 114 to adjust the pitch transmitter 72. A switch 131 similar to and for the same purpose as switch 121 is also provided. Specification 662,145, [Group XL (a)], is referred to.

Title: Word-Organized, Content- Addressable Memory
IPC: G06F17/30
Filed: 1978-12-15
Abstract: In order to reduce the number of pins required on its encapsulation(s) when a word-organised, content- addressable memory is constructed in integrated circuit form the "correspondence" signal output (M1) of each word location (36) is coupled to an "information-transfer-enable" signal input thereof via a signal path which can be blocked if a bistable validity indicator (39) is in its reset state. If this is so and a "write in a free word position" signal (WFP) is applied to the arrangement after flip-flop 42 has been set the corresponding word location will be activated provided that a multiple match resolver or sequence generator (42, 46, 48, 49, 80, 81, 140) gives that location priority. If the validity indicator is in its set state application of a masked keyword (37) will cause the corresponding word location to be activated if correspondence occurs provided the sequence generator gives the location priority. Selected validity indicators can be reset by applying a keyword and a "clear part of memory" signal (CPM) to the arrangement. Output 140 is connected to the input 81 for the following word location (36). <IMAGE>

Patent GB-2045024-A (GB)
Title: Frequency and amplitude control of frequency sources
IPC: H03L5/00
Filed: 1979-03-22
Abstract: An accurate and stable frequency source utilises a narrow band pass filter 3 e.g. SAW filter to determine its frequency of operation. An amplitude detector 11 monitors the amplitude of the output signal and modifies the phase shift present in the oscillator feedback loop so as to bring the output frequency to the centre of the pass band characteristic of the filter so as to maximise the output amplitude. The oscillator includes a controllable phase shifter 4 in its feedback path and the circuit for maintaining the oscillator frequency and amplitude includes the amplitude detector 11 producing a binary output, a complementary exclusive OR gate 15 and a ramp generator 13 for varying the phase shift in either direction. <IMAGE>
Patent GB-2025171-A (GB)
Title: Phase locked loops
IPC: H03L7/089
Filed: 1979-04-03
Abstract: In an arrangement for very rapid tuning of a phase-locked loop a fixed oscillator (26) feeds a frequency F2 to a phase comparator (24) via a fixed divider (30), while VC0 (16) feeds a frequency Fi to the comparator (24) via an adjustable divider (12). In response to a phase error, the comparator (24) energises a line (36) to adjust the VCO (16) in the usual way. In addition, however, a change in desired frequency causes the comparator (24) to hold up the operation of one or other of the dividers (12, 30) according to the sign of the phase error, and to allow it to restart in synchronisation with the other one so as to bring the VCO frequency to the correct value. A damping circuit 70, 72 for the loop filter (38) is only required when the phase error is less than the clock period of the dividers as detected by circuits 76A-90 and is switched in only during those times. The divider 12 may be adjusted according to a predetermined programme. A loop amplifier 42 may compensate for the non-linearity of the oscillator 16. <IMAGE>
Patent GB-2025429-A (GB)
Title: A Process for Reducing the Monomer Content in Expandable Beads of Thermoplastic Materials
IPC: C08J9/22
Filed: 1979-06-08
Abstract: The residual monomer content of expandable thermoplastic beads containing a volatile blowing agent, which are produced from ethylenically unsaturated monomers by a conventional aqueous suspension polymerization process in the presence of the blowing agent, is reduced by heating a slurry of the beads in a vessel completely filled with a liquid medium and in the presence of a water soluble polymerization initiator at a temperature exceeding 65 DEG C. The liquid medium preferably includes the aqueous polymerization medium used so that the process also removes monomer residues therefrom. Expansion of the beads during the heat treatment is inhibited by the pressure of the liquid medium, which has no interface with any gaseous phase. The process is particularly useful for treating expandable beads formed from the copolymerization of (meth)acrylonitrile with monomers such as styrene or vinylidene chloride.

Patent GB-2031567-A (GB)
Title: Sliding gate valve
IPC: B22D41/26
Filed: 1979-09-24
Abstract: A sliding gate valve of the type in which refractory gates (17, 17') are sequentially disposed in operative position beneath the pour opening from a teeming vessel, such as a tundish, is effective to throttle the metal flow stream from the vessel. Means (84) for positioning the gates in order to control the degree of throttling of the flow stream are independent from the means (74) for disposing the gates in their working position within the valve mechanism whereby the flow stream can be terminated without adjusting the throttling configuration of the valve. Means are provided, when the valve employs a pour tube (19) attachment, for selectively changing gates and pour tubes in unison, or independently from one another. The valve mechanism and its replaceable refractory components are designed for the supply of fluids for cooling these members and for the injection of inert gas to stir molten metal in the flow passage during holding periods. <IMAGE>
