Filed: 1976-08-25
Abstract: 1505619 Tuning radio receivers; disabling AFC PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 25 Aug 1976 [28 Aug 1975] 35334/76 Addition to 1,429,965 Heading H3Q In a broadcast receiver such as a radio or TV, level variation of the voltage at a top of a potentiometer 125 which is ganged to a tuning potentiometer 119 is detected by a circuit 115 and an AFC signal from an AFC control circuit 109 is suppressed. The AFC is suppressed from output 12 of an integrated circuit 115 when the receiver is switched on or when the tuning potentiometer 119 is varied on detection of the level variation of the voltage at the top of the potentiometer 125 by means of a differentiation network 129, 131 and amplifier 133 and circuit 115. After a delay provided by a capacitor 117 the AFC signal at 8, 9 from frequency or phase detector 109 is obtained at output 12 and is superimposed on the tuning voltage from the potentiometer 119 which is connected to an oscillator 103. Circuit 115 can be replaced by a circuit of similar function disclosed in Parent Specification. The output from the amplifier 133 may also be used for automatically changing over the tuning from remote to local control. Manual and motor tuning can be used.

Title: Improvements in and relating to springing arrangements for motor and like vehicles
IPC: B60G11/18
Filed: 1934-12-10
Abstract: 428,829. Vehicle spring suspensions. PORSCHE GES., DR. ING. H.C. F., 24, Kronenstrasse, Stuttgart, Germany. Dec. 10, 1934, Nos. 35502, 35503, and 35504. Convention dates, Dec. 8, 1933, July 4, 1934, and Nov. 6, 1934. [Class 108 (ii)] In a system for springing the half-axles of motor &c. vehicles by means of torsion springs, the stresses are communicated from each of the half-axles through the medium of two links which with the half-axle form a quadrilateral linkage. In the construction shown the half-axles 2, 2<1> swing in bearings 4, 4<1>, about longitudinal axes A, A<1> and are connected by links 17, 18 with the torsion bars 8, 8<1>, which are journalled in bearings 11, 12 so as to swing about axes B, B<1> parallel to the frame members 6, 61. Since the axes A, A<1> and B, B<1> are not exactly parallel the occurrence of bending stresses in the links 17, 18 is avoided by interposing between them a flexible joint comprising a pin 20, Fig. 5, which passes through an initially stressed rubber sleeve 22. The other ends of the links 18 are connected either directly to pins on the half-axles, or, as shown in Fig. 5, to pins 21 on a ring 25 carried by a grooved sleeve 26 which is capable of screw adjustment on the axle either by hand or from the driver's platform by chain gearing. By use of such an adjustable sleeve 26, the load-deflection curve for the spring system may be made to approximate to a pre-selected form. At its forward end the torsion bar 8 has a fluted connection with a bracket 14, the angular position of which may be altered by an adjustable tension-bolt 15, Fig. 3, to vary the initial stressing of the spring 8. In a modification each half-axle is guided by means of a longitudinal radius arm swivelled to the frame about an horizontal axis that passes through the centre about which the half-axle turns. In this case the link 18 is located above the half-axle and is provided at each end with balls engaging spherical sockets on the halfaxle and link 17 respectively.

Abstract: 1,046,327. Door operating mechanism. B. KOFYAN. Aug. 31, 1964 [July 22, 1964], No. 35526/64. Heading E2M. The sliding door 5 of a cold store is opened by pneumatic means which first lifts the door off the ground and away from its frame, and then moves the door away from the door opening for a period controllable by the operator through a time switch 14. The door is then returned automatically to recover the opening. The system includes air distribution and control units 3, 4 and hydraulic jacks 7, 10. When the door is to be opened, the pneumatic circuit is activated by closing a key-operated contact 1 and then pressing a start button 2. A switch 16 is then operated by a pull rod 6 and this causes the control unit 4 to supply air to the jack 7 so lifting the door from the ground and out of contact with the door frame. The upward movement of the door ultimately operates a microswitch 9 stopping the air feed to the jack 7 and transferring it to the jack 10 which moves the door horizontally away from the door opening. The door remains open for the time determined by the time switch 14 after which the jacks are pressurized in the reverse order to replace the door over the door opening.

Abstract: 978,629. Digital computers. THOMPSON RAMO WOOLRIDGE Inc. Sept. 12, 1963, No. 36016/63. Heading G4A. A digital computer adapted to store a plurality of routines each of which may include a plurality of subroutines has an input device with first means for dispatching a coded message to the computer identifying a particular routine and second means for dispatching a coded message identifying a particular subroutine in any routine. As described, a particular computer routine is selected by placing a corresponding "overlay" 38, Fig. 2, in position to co-operate with a keyboard 24, which forms part of a computer console comprising manual input keys and an indicator cathode ray tube and lamps. Each overlay carries a projection 53 which closes a switch 54, Figs. 2 and 4 and a characteristic combination of projections 46 adapted to close a combination of switches 48, 50, 52 representative of the particular overlay. When a particular overlay is in place, a key R1 is depressed thereby energizing a relay 78, Fig. 4, which holds, extinguishing an indicator lamp 86, and causing transmission to the computer via switches 48, 50, 52 and diodes 68, 70, 72 of a signature code representing the particular overlay. This signature is compared in the computer with that of the routine in the computer "active" file, and the computer operator can depress keys R2-R7 selectively according to the subroutines it is required to initiate. Depression of a subroutine key R2-R7 causes transmission to the computer via diodes 100-116 and data lines # 1-3 of a corresponding code which is distinguished from an overlay signature code by the absence of a signal on signature line # 1. The computer then performs the selected subroutine. Writing a routine in the "active" file or the performance of a subroutine causes appropriate data to be written into a circulating register 180, Fig. 10, which may include a drum thereby controlling lamps LC1-LC9 to indicate to the computer operater which keys can be depressed next, a lampLR1-LR9 being illuminated under the last depressed key to indicate the previous subroutine selected.

Abstract: 849,104. Multi-stable-state circuits. SIEMENS EDISON SWAN Ltd. Dec. 14, 1956 [Dec. 16, 1955], No. 36185/55. Class 40(6). [Also in Group XXXVIII] A bistable circuit comprises a cold-cathode gasfilled diode which is triggered into an operative condition by a voltage and which then commences a cyclic operation such that the diode is repeatedly struck and extinguished in correspondence with input pulses applied to the circuit. An energy storage device is associated with the diode such that the voltage developed by this storage device during one part of the cycle augments the input pulse voltages and causes the diode to strike during a subsequent part of the cycle. Fig. 1 shows a bistable circuit comprising a symmetrically conducting cold-cathode gas diode D1 to which alternative positive and negative pulses are applied at terminal PS1. Positive-going triggering pulses are applied at terminal TP1 so that a pulse causes diode D1 to strike and capacitor C1 charges from the current flow through diode D1 initiated by the pulses applied to terminal PS1. At the end of the first input pulse at PS1 diode D1 extinguishes. Since the succeeding pulse at PS1 is of reverse polarity its voltage is added to that left upon the capacitor causing diode D1 to strike in the reverse direction so that capacitor Cl is discharged and recharged with opposite polarity. This recharge assists in the re-striking of diode D1 when the next input pulse is received at terminal PS1 so that in this manner the diode continues to strike in alternate directions. The output pulses caused by the striking of the diode are differentiated by network Cl, D1 and appear at output terminal M1. It is demonstrated that the effective output voltage obtainable from the circuit is approximately twice that obtained from circuits in which the voltage produced across the capacitor C1 are not used to assist the striking of the diode. In a modification shown in Fig. 2 the capacitor C2 is placed in series between the input pulse source at PS2 and the diode D2. In a further modification shown in Fig. 3 two asymmetrically conducting gas diodes D3 and D4 are used, the storage capacitor C3 being connected between the diodes and the pulse source PS3. After a given diode has been struck by a triggering pulse applied to the terminal TP3 the train of pulses applied at terminal PS3 cause the diodes D3, D4 to fire alternately and to be extinguished in correspondence with the input pulses at PS3. Output pulses are derived at terminals M3, M4. A group of such bistable circuits may be associated as a code converting circuit (see Group XXXVIII) or for switching in an automatic telephone exchange system.

Abstract: 359,779. Valve-gear for rock drills. INGERSOLL-RAND CO., 15, Exchange Place, Jersey City, New Jersey, U.S.A. Dec. 3, 1930, No. 36474. Convention date, Jan. 16. [Class 122 (ii).] A rock drill has a fluidactuated lift valve S provided with a pair of flanges V, Wand a stem T which is housed in a chest O at the rear of the tool. The valve has a recess U the end of which constitutes an actuating area j, the exterior of the stem forming another area o to which pressure fluid passes through a port p. The fluid is supplied through an inlet Y, an annular passage Z, and ports X to the space between the flanges. Ports e, f in the flanges allow pressure fluid to pass to the areas g, h on the exterior of the flanges V, W respectively and to the cylinder ends during working. Fluid passes to the ends of the cylinder through a port b in a plate H closing the cylinder end and passages c, d. The ports e are larger than the ports f. An actuating area b is also provided on the flange W. When during forward motion the piston passes the exhaust port E, the pressure of the fluid on areas h, o and the front cylinder end compression on the area k move the valve forward ; the additional pressure on the area k as the supply fluid passes to the forward end of the cylinder accelerates the valve motion. An auxiliary exhaust passage r opens the end of the stem to atmosphere on the completion of the valve motion. During the return stroke, when the top of the piston passes the exhaust port E, the pressure on the area g and the compression pressure on the area j reverse the valve.
