Title: Improvements in or relating to electrical remote control systems
Inventor: POPE BERNARD WALTER
IPC: H02J13/00
Filed: 1959-01-16
Abstract: 873,768. Electric selective signalling systems. GENERAL ELECTRIC CO. Ltd. Jan. 11, 1960 [Jan. 16, 1959], No. 1688/59. Drawings to Specification. Class 40 (1). An electrical remote control system comprises, at a controlling station, means to transmit to a controlled station electric signals of different character one at a time in a regular recurrent sequence of cycles in response to the initiation of a control and, at the controlled station circuit means which is for effecting control when it is operated in accordance with a predetermined sequence of steps and which is arranged to be operated in accordance with that predetermined sequence of steps only upon the reception from the controlling station of a predetermined number of consecutive cycles of the signalling sequence during which cycles the component signals are received one at a time and the duration of each component signal lies within predetermined limits, and means which is to detect operation of said circuit means that is not according to said predetermined sequence and which is arranged so that, upon its detection of such abnormal operation, said circuit means is restored automatically to a condition from which operation in accordance with said predetermined sequence of steps may recommence. As described the control station normally transmits two frequencies # 1  and # 2  simultaneously to the controlled station. When a control is to be effected, this being signified by the closure of a contact at the control station, the simultaneous transmission of f 1  and f 2  is replaced by the alternate transmisrion of f 1  and # 2 . This causes circuitry at the controlled station to progress through a sequence of conditions which result eventually in the closure of a contact which effects the desired control. The circuitry at the controlled station, which consists entirely of electromagnetic relays, is so arranged that for the control to be effective a sequence of six frequencies (f 1 , f 2 , # 1 , # 2 , # 1 , # 2 ) must be received and each frequency must be of a duration which lies between two preset limits. If the sequence is not completed, or if any frequency is not of the correct duration, the control is not effected, an alarm bell and lamp are energized, and the circuitry restores itself to a condition from which it can respond to a further control.

Abstract: 917,459. Disc brakes. GIRLING Ltd. April 19, 1960 [Jan. 17, 1959], No. 1810/59. Class 103 (1). A disc brake comprises a housing 13, 14, 15 containing a rotatable disc 10, Figs. 1, 2, adapted to be gripped between the housing and an axially movable plate 24, and cam means between the plate 24 and the housing to move the plate axially when the housing and plate are urged angularly in opposite directions, the housing having a limited angular movement. Balls 25 are contained in conical recesses in the housing and plate 24 which is biased by springs 26 away from disc 10. Toggle links 27, 28 are connected to lugs 29, 31 on the housing 13, 14, 15 and plate 24 respectively and are drawn together by pull in a rod 36 to rotate the housing and plate in opposite directions, the ball 25 moving plate 24 axially to engage and move disc 10 and apply the brake. The housing and plate then rotate with disc 10 until lug 29 or 31 engages a fixed abutment 37 or 38, resulting in further relative rotation of the housing and plate for stronger braking, the housing rotating on a fixed sleeve 17. In Figs. 3-5 (not shown), the links 27, 28 are replaced by two bell-crank levers engaging one with an abutment on the housing and the other with a tappet extending through the housing and into a tangential slot in the pressure plate; a screw-threaded stud in said other lever engages the tappet to permit adjustment for wear. In Fig. 7, the sleeve on which the housing rotates, has three splines 76, the housing. 67 and plate 71 having lugs 78, 77, respectively, extending into the gaps between splines 76 so that on rotation of housing 67 and plate 71 with the disc either lugs 78 or 77 engage the splines 76 to stop such rotation. The brake disc may be fixed axially with the housing mounted for limited axial movement. The rings or pads 12 of friction material may be secured to the disc 10 or to the plate 24 and the housing.

Title: Associative store
IPC: G11C15/00
Filed: 1964-01-16
Abstract: 987,666. Associative store. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 16,1964 [Jan. 24, 1963], No. 1904/64. Headings G4A and G4C. In an associative storage system having a store 1 of the magnetic or cryogenic type with a plurality of equal length words W 1 , W 2  ... W 2  for storing variable length data words, a first associative register 2 of equal length to the storage words is adapted to shift argument words therethrough for comparison with the store 1, and a further register 3 receives words shifted from said first register for further comparison with the store 1. The data word is shifted from register 2 via an intermediate register 9 to register 3 whereby control means indicates the presence of a "Spillover" word in the second register 3. The system is operated by a clock 6 generating a cycle of fine pulses. A first pulse resets the store 1 and interrogates the last character position 9 to determine whether a "spillover" into the second register has occurred. An "after spillover" condition causes the contents of register 3 to be read into the store 1 by a second pulse and compared by a third pulse which triggers flip-flops in circuit 7. Any match present is stored in the single match circuit and the last two shift pulses are blocked in order that the first register 2 may be compared by a further clock pulse cycle with the store 1 and a further match is indicated in a consecutive matching circuit 8. If no match occurs in the second register the fourth and fifth pulses shift the data word one step to the left and the operation is repeated. For data words of greater length than two store words further "spillover" registers are employed.

Title: Improvements in Carburettors for Internal Combustion Engines.
Inventor: DODSON EDWARD
IPC: F02M7/10
Filed: 1916-02-11
Abstract: 103,193. Dodson, E. Feb. 11, 1916. Spray carburettors.-A fuel nozzle, or a pair of concentric nozzles enter the induction passage near the controlling edge of a barrel-shaped throttle valve, the nozzle or nozzles being subjected, at small throttle openings, to the ejector action of a current of air, which action gradually diminishes, and may ultimately be reversed, as the throttle is opened. A central nozzle E fed from the fuel chamber e, and an annular nozzle F, fed from a well open to atmosphere and supplied through a calibrated or compensating orifice, deliver into the induction passage a near the control port D of the throttle valve B which port is so shaped as to maintain a constant air flow over the nozzles. Between the nozzles is an air conduit G which communicates with the atmosphere at g' and, through a passage H, with a constricted part of the induction passage a. The passages g', H are controlled by valves J. I. The throttle valve has an air inlet f controlled by a screw i. At small throttle openings air, through the conduit G and heated preferably by the exhaust, exerts an ejector action at the nozzles, but as the throttle opening is increased, this action diminishes owing to the lower pressure existing at the constricted part of the passage a which may ultimately cause a reversal of air flow through the conduit G and passage H.

Title: Photographic shutter
IPC: G03B7/083
Filed: 1956-01-20
Abstract: 785,577. Photo-electric control arrangements. AGFA CAMERA-WERK. AKT.-GES. Jan. 20, 1956 [Jan. 22, 1955], No. 2070/56. Class 40 (3). A photographic shutter is arranged to permit manual control or automatic control by means of a photo-electric device and the member which is used in the manual adjustment of the shutter also effects the engagement and disengagement of the automatic control. Fig. 1 shows a shutter-housing 1 carrying a setting ring 2 provided with an additional position 7 beyond the highest fixed speed which brings into action the otherwise inoperative photoelectric control. When the position 7 is used (as shown) the tensioning lever 3 makes contact with the cam face 20 on the side of arm 19 of three-armed lever 10 pivoted at 9. Arm 11 of this lever is coupled to a piston 14 operating in cylinder 13. This arrangement forms a pneumatic retarding device and the rate of air flow through hole 30 is determined in accordance with the position of meter indicator 18 coupled to photo-cell 15. Operation of the shutter causes lever 3 to move from the position shown in full to the position showed in dashed outline under the influence of an internal spring (not shown) against the tension of return spring 29 and at a speed determined by the retarding device 13, 14, 30. Movement of the setting ring 2 to cause one of the manual speed setting marks to come opposite index 6 causes the end 25 of arm 22 to be lifted out of the depression 28 in the setting ring and the opposite end of lever 22 bears down on arm 21 of lever 10 and lifts arm 19 clear of the lever 3. The automatic control is then isolated from the shutter which is timed in accordance with normal delay means contained in it. The Specification also describes with respect to Figs. 3, 4 and 5 (not shown) a setting arrangement which may be attache I to the front of a conventional manually adjustable camera shutter mechanism to allow for an automatic control position. The new setting ring and the old move together over the manually adjustable speed scale but due to the coupling between the two allowing the further motion of the new ring beyond the highest speed setting on the old there is an additional position for automatic control. Levers 10 and 22 and a similar photo-electric shutter control to that already described may be arranged for use in conjunction with the added setting ring. Specification 748,406 is referred to.
