Patent GB-861272-A (GB)
Title: Call recognition system
IPC: H04L12/40
Filed: 1959-05-08
Abstract: 861,272. Devices responding to particular call signals. COLLINS RADIO CO. May 8, 1959 [Sept. 2, 1958], No. 15906/59. Class 40 (1). A circuit adapted to recognize a particular call signal consisting for example of three characters, represented each by a series of pulses, comprises a comparator in which the received signals are compared with stored signals read out synchronously with the incoming signals, a counter counting the received characters being reset by a disagreement signal from the comparator, the reception of the proper calling signal being indicated by the count of three. In the form of Fig. 1 the signal consists of a character repeated three times (e.g. YYY). The comparator 41 receives the call signals on line 15 and the stored character on line 40. A start pulse passes through gate 11 which is disabled by input 34 from trigger 31 immediately after the first pulse. A " false start " gate eliminates spurious pulses of short duration and supplies a synchronizing pulse on line 16 for each received character. A binary counter 21 controlling the read out from the character store 28 is set going by a synchronizing pulse through OR gate 17. The outputs from the three stages of this counter are translated in a matrix 26 to sequential outputs on seven lines 71-77. Line 71 gives a start pulse, lines 72-76 correspond to the five character bits and line 77 gives a stop pulse. The start pulse operates a control trigger 31 to start a multivibrator 36 providing a sequence of pulses the rate of which is equal to the rate of the incoming signals. Counter 21 and comparator 41 are both controlled by these pulses through gate 17 and gates 42, 43. The following five pulses on lines 72-76 enable gates G1 to G5 in turn to read out the bits of the stored character Y. The character is set up by connectors joining certain ones of five pairs of terminals 51-55. The connections shown produce a signal " 10101," representing character " Y." This character is applied through OR gate 29 to the comparator 41 where each input is gated with the other input inverted and an output from either gate on line 48 indicates a disagreement. The character signals on line 16 are counted on a two-stage counter 61. This counter is reset by a disagreement signal on line 48 but if it reaches a count of three, showing that threee consecutive Y's have been received, an output is produced on line 66 via gate 64. The number of repetitions of the desired character required in a proper call signal may be increased either by increasing counter 61 or by adding a further counter at terminal 66. The output may control the operation of a typewriter. A circuit is also described which responds to three different letters, these being set up as in the store 28 and read out in turn by a third counter.

Abstract: 119,665. Compagnie des Forges et AciÞries de la Marine et d'Homecourt. May 8, 1914, [Convention date]. Addition to 119,664. Field carriages. - Relates to carriages having divided trail beams as described in the parent Specification in which the effective length of the trail is reduced, when the beams are swung together for limbering-up, by a combined longitudinal and pivoting movement. According to the present invention, a special pivotal sliding joint is provided between the trail beams and their junction piece. In 'the form shown in Fig. 1, the trail beams 34 are brought together and their effective length reduced by moving the beams successively into the positions 1, II, III, IV. To effect this, each beam, after turning a cut-away locking bolt 37, is rocked about a pivot 38, moved forwards by the sliding of the parts 39 in guides 40, and locked by the engagement of a projection 42 in a recess 43. The Specification as open to inspection under Sect. 91 (3) (a) describes also, with reference to Fig. 7 (Cancelled), an alternative arrangement for swinging the trail beams together for limbering- up. The beam 44, fixed to the junction-piece 1, is first swung into line with the longitudinal axis of the gun, and the beam 46 is then swung on a pivot 45, relatively to the member 1, and locked by a projection 47 engaging a recess in the axle. The beam 44 may be used as a rolling track for dismounting the gun barrel. This subject-matter does not appear in the Specification as accepted.

Abstract: 626,571. Preventing formation of ice on aircraft. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. June 18, 1947, No. 16049. Convention date, Aug. 17, 1945. [Class 4] [Also in Groups XXVI and XXXIV] A grille located at the inlet to the air compressor of the gas turbine power plant is formed of a plurality of tubular members through which the oil of the lubricating system is circulated to cool the oil and to prevent formation of ice on the grille. The grille is formed of two groups of parallel spaced tubes 38, 39, spaced adjacent and approximately at right angles to each other and for rigidity the trailing edges of one group of tubes are notched and the leading edges of the second group of tubes welded into the notches. Hot lubricating oil from the scavenge pump is passed through the tubes 38, 39. Arranged in parallel with the grille 36 is a spiral heat exchanger 51 forming part of the outer wall of the annular inlet 12. The hot oil from the scavenge pump passes to a distributer 52 which apportions the lubricating oil supply between the grille 36 and heat exchanger 51. The distributer 52 may be thermostatically controlled so as to maintain the grille at a temperature which prevents ice formation. The cooled oil leaving the grille and'heat exchanger returns to an oil reservoir 41. The inlet and outlet headers 56, 57 extend approximately 180 degrees around the inlet and overlap at 58, Fig. 3, so that as to provide an outlet for each tube in both groups of tubes.

Abstract: 707,218. Speed governors. MONO-CAM, Ltd. June 14, 1950 [June 17, 1949]. No. 16238/49. Class 57 [Also in Group XXVIII] In a fuel injection pump having a plurality of plungers 7 whose effective delivery strokes are controlled simultaneously by control sleeves 17. fitted over the plungers, which are adjusted by a common disc member 14 to vary the opening of spill passages in the plungers to a chamber 3 communicating with the pump inlet, the disc member is connected to a rigid part 20 of the pump housing by a pressure responsive flexible member 32 which is exposed to the pressure in one of the manifolds of the engine supplied by the pump so as to cause the member to reduce the pump delivery as the engine speed increases. The pump is of the kind described in Specification 580,354, [Group XXVIII], in which the plungers are actuated by an axial cam through a push rod 23. A metallic bellows 32 is subjected internally to the inlet manifold pressure through passages 34, 35, 36, 37. Alternatively the bellows may be connected with the exhaust manifold and act on the member 14 in the opposite direction. The regulating member which is loaded by a spring 50 may also be adjusted by a lever 41 through a rod 39 to determine the delivery setting. Spacing washers 52 are interposed between the member and the rod to vary the spring loading. A collar 46 on the rod co-operates with a shoulder 47 and with an adjustable sleeve 48 to limit the minimum and maximum delivery respectively. Specification 707,217 also is referred to.

Title: Braking arrangement for high speed suspension railway
IPC: B61H7/02
Filed: 1926-06-28
Abstract: 272,347. Kruckenberg, F., and Stedefeld, C. June 28, 1026. Actuated or applied by weight of vehicle; skid. - High-speed suspension railway cars are provided with spring-mounted shoes which support the car in the event of failure of any wheel of the running gear in substantially the same position as the running gear. These shoes also act as rail brakes and shoes may be made to press automatically against the bottom of the rail. The shoes 10 are connected to a member 19 by springs 18, preloaded by stirups 20 to prevent chattering. Screwed spindles 22 are adapted to apply the shoes to the rails and an arm 23 rests on the springs 18 when the brakes are fully applied, the member 19 sliding in guides 24 of a frame 25 allowing for oscillations of the car. A spring 27 tensioned by means of a trigger 30 and a tensioning screw 28 exactly to the weight of the car carried by the running gear supports, by a collar 29, the frame 25 which is slidable in guides in a member 26 integral with the frame of the car. In the event of the running gear failing the weight of the car brings the upper shoe 16 into contact with the rail and an arm 35 on the frame 25 into contact with the arm 23 integral with the shoe-carrying member. The shock causes the spring 27 to be deflected, allowing the frame 25 to slide in the member 26 and the trigger 30 to be released which may operate a pneumatic device to rotate the spindle 22 and apply the lower brake shoe to the rail. Binding of the shoes is prevented as they are pivoted at the forward end and are hooked over an arm at the other end. The shoes may be carried at the ends of hinged levers the other ends of which are moved by mechanical, pneumatic or hydraulic means. The shoes and rails are curved to allow sideways movement. The guides may be of cylindrical form guided in holes, and the spring 27 may be replaced by coil springs within the cylindrical frame members 25.

Abstract: 673,294. Valve-discharge water-wastepreventers. GRIFFON, C. June 29, 1950 [July 8, 1949; June 3, 1950], No. 16298/50. Class 26 A water-waste-preventing cistern of the type comprising two superposed interconnected containers a, i having a mains water inlet e into the lower container and a ball valve b which may close the outlet pipe d from the container, is characterized by having a permanently open connection between the two containers so that the whole of the lower container and a part of the upper container are filled with water. In one form, Fig. 2, the upper container i has a depending flange i<SP>2</SP> which caps the lower container a when a connection i<SP>1</SP> is secured on to a construction a<SP>2</SP> to hold the exhaust washer k in place. While the containers are filling the ball valve b is held by water pressure on the seating c, but when operation of an operating lever (not shown). causes the member g<SP>1</SP> to lift the ball b off its seat, the ball rises and the air compressed in the container i above the water level forces the water into the outlet pipe d. In another form, Fig. 6, the cistern comprises a cylinder n and the connection between the two parts, formed by the cover q, is by an externally threaded tube s, having a closed slotted head s<SP>1</SP> and an opening s<SP>2</SP>. The position of the opening s<SP>2</SP> relative to the cover q is therefore adjustable by rotation of the tube s. The actuating handle z has an enlarged shoulder z<SP>1</SP> fitting within a carrier f and forming a chamber f<SP>2</SP> into which water leaking past shoulder z<SP>1</SP> collects. The threaded portion of carrier f has a slight clearance within its tapped hole in the sleeve x and this is connected by a small port (not shown), with the recess carrying the packing u. The packing u thus rises slightly under suction when the containers empties, and thus objectionable rebounding is prevented when the ball b returns to its seat.

Abstract: 1393183 Folding reflex self-processing cameras POLAROID CORP 5 April 1973 [24 April 1972] 16372/73 Heading G2A A folding single-lens reflex camera of the general design disclosed in Specification 1329536 has a plate 120 which shields the film unit 46 from ambient light as it passes from the processing rollers 34, 36 towards the exit 128. After exposure the film unit passes out of the magazine 44 through opening 54 to enter the nip between the rollers. The magazine has a number of projections 112 extending into the opening 54 which exercise some control over the movement of the processing fluid, by flattening the meniscus, as it is spread between the sheets of the film unit. The front portion 114 of the magazine, from which the projections 112 depend, is thin enough to have a certain flexibility, and such flexing may be undesirable during film processing. The camera therefore has a rigid support part 116 against which magazine portion 114 is seated, which prevents such flexing. The plate 120 is pivoted to the camera housing section 28 by a spring 122 which urges it anticlockwise against a stop 124, so that it is maintained in its operative position as long as the camera is unfolded for operation. The film unit is ejected from the camera through an opening 128 which is closed by a resilient flexible sheet 130 secured to the housing. As the film unit leaves the rollers 34, 36 it impinges against plate 120, and is deflected downwards against the edge 132 of sheet 130. This is in turn deflected, so allowing the film unit to pass out of the camera.
