IPC: B60J1/14
Filed: 1927-07-05
Abstract: 297,898. Starling, C. E. B., and Starling Co., Ltd. July 5, 1927. Windscreens. -Relates to side-screens for vehicles of the kind in which two or more panels foldably hinged together are adapted to pivot or slide into or out of a pocket or recess in the side or door of the vehicle. According to the invention the hinged panels which, in the erected position, are adapted as usual to form a screen wider than the pocket for housing them, are transferred from the operative position by first folding the panels together, and then moving the screen as a whole into the pocket either by a hinging movement and a subsequent sliding movement, or by a combined hinging and sliding movement. One of the panels is provided with a bracket or similar attachment adapted to slide in or on one or more vertical guide bars located in the pocket. In the construction shown in Fig. 1, the screen comprises two panels 1, 2 hinged together at 5, and the panel 1 has attached to its lower edge a bracket 6 formed integrally with a sleeve 8 slidable on a vertical bar 9 in the pocket 24. In erecting the screen a sector-shaped projection 16, Fig. 3, on the bracket 6 co-operates with a similar projection 17 on a fixed door bracket 14 to position the screen correctly, while projections 26 on the door serve directly to support the screen. The upper portion of the pocket 24 is provided with a hinged closure flap 19 having a ledge 20 for sealing the upper edge of the pocket 24. Catches 27, 28 serve to secure the screen in the erected and folded positions. To stow away the screen, the panel 2 is folded on to the panel 1, both panels are then swung through 180‹, and dropped into the pocket, and the flap 19 closed. Modifications are described in which the folded screen is lowered into the pocket by a sliding movement in a slotted bar, the slot of which has a horizontal extension at its upper end, by a combined pivotal and sliding movement on a pair of guide rods connected to a hinged lever, and by, a combined pivotal and sliding movement, on a single pivoted bar. According to further modifications, a spring may. be added to assist in raising the screen from the pocket, and the screen may be mounted upon a lazy-tongs, which allows the screen to be raised from the supporting bracket.

Title: Improved gear shift
IPC: F16H59/04
Filed: 1929-06-12
Abstract: 327,341. Dunlop, S., (Universal Gear Shift Corporation). June 12, 1929. Controlling variable-speed gearing.-A gearshift selector comprises a distributing-valve 24, Fig. 1, for connecting a port 160, Fig. 6, supplying pressure fluid to one of a number of ports 76, 78, 80, 82, all the ports being in a flat base plate 50 of sector shape adapted to be clamped at 44 to a support, such as the steering column of a vehicle. A valve element 52 slides angularly over the plate 50 and has a circular groove 110, which remains open to port 160 as a finger 98 moves over the ports 76 - - 82. A groove 100 under the finger 98 completes the connection for passage of air &c. The valve 52 is held down by a spring 106, Fig.. 5, which abuts against a cover plate 86. The valve is turned through a post 94 by a handle 108, which moves over a quadrant indicator 120 and is locked by spring ball 128. The peripheral ports 76 - - 82 are connected by four or five ducts 60, &c. to gear-shift cylinders which " bleed " noiselessly into the valve casing. The main port 160 is connected through the fifth of the ducts 60 and through a. check valve 40, Fig- 1, to engine suction. This valve is to prevent the vacuum in the selector valve being lost if the vehicle stalls on a hill. It comprises hemispherical parts 144, 146, Fig. 18, separated by a diaphragm 150 and held together by a through bolt 148. A spring 161 surrounding bolt 148 normally holds leather &c. valve washer 154 down over ports 152 in the diaphragm. Pipes 30, 32,. Fig. 1, lead to a double-acting cylinder which operates a rod 190, and pipes 34, 36 lead to a similar cylinder-operating rod 192. Each cylinderhas a spring which returns the piston when displaced either way from mid-position. Two selector-bars 166, 168 slide on the top of the gear box and carry striker-arms 194 connecting to gearchange elements. Four movements of the two rods correspond to the markings 3, 2, 1, R of valve 24. The bars 166, 168 are interlocked so that one only can be moved by a pair of flat discs 204, Fig. 14, which slide laterally in a fixed slot 202.

Abstract: 814,185. Transistor generating and two stable state circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 12, 1957 [June 12, 1956], No. 18085/56. Class 40 (6). In a circuit employing a junction transistor 1, Fig. 1, the base is so biased relative to the emitter that the transistor operates in the avalanche mode with a base current equal to or greater than that which occurs at the " critical point " in the collector current-voltage curve, Fig. 2. It is stated that as the reverse base current is increased, the characteristic curves 10 ... 19 are traced out to provide a curve 20 as the locus of the discontinuities in the curves, the point 21 where the curve 20 reverses its direction being the " critical point." The base of transistor 1 is reversely biased by supply 3 on resistor R2 and is triggered to a highly conducting state by a positive pulse applied over the capacitor Cl and reset by a negative pulse. A capacitor may be connected between collector and base, Fig. 4 (not shown), so that the negative impedance causes the circuit to generate sawtooth waves.

Title: Improvements in or relating to timing devices using thermionic valve circuits
IPC: H03K17/288
Filed: 1946-06-17
Abstract: 613,565. Valve relay circuits. HERCOCK, R. J., NEALE, D. M., and ILFORD, Ltd. June 17, 1946, No. 18134. [Class 40 (vi)] An electronic timing device in which the timing may be precisely adjusted and in which the use of very large capacitors is avoided, utilizes the Miller effect of a valve. As shown, when the press-button switch PB is closed, relay RL operates and is held in the operative condition by the hold-on circuit via contact a4 and resistor R3 and the lamp L is lighted. Capacitor C charges via resistors R6 and R1, the Miller effect of valve V1 increasing the effective capacity between grid and anode. When contact a1 opens, the grid of valve V1 is connected to a more negative potential, the current in the valve is reduced and the potential at the anode of V1 rises. The grid of thyratron V2 becomes increasingly positive until the thyratron strikes, a heavy current then flowing through its anode circuit causing relay RL to release, the lamp L to be extinguished and the capacitor C to discharge through contact a1. The feedback on valve V1 causes the charging curve of capacitor C to be substantially linear over a considerable portion of its length curve B, Fig. 1 (not shown). Resistors R8 and R9 may be adjusted to give operation over a suitable portion of the charging curve and to improve the linearity the grid of valve V1 may be returned to a point at a high positive potential with respect to its cathode. In a modification, Fig. 3 (not shown), the time of operation of the lamp is made substantially independent of variations in H.T. supply, by including in series with the resistor R9 a non- linear resistor, such as a low voltage tungsten filament lamp, which has a resistance increasing with increase in the current flowing through it. The capacitor then charges to a higher voltage as the H.T. voltage increases, thus reaching a given voltage more quickly and counteracting the normal effect of a rise in H.T. voltage which causes an increase in the charging time. In a further modification, Fig. 4 (not shown), the grid circuit of the valve V1 is returned to a tapping on a potentiometer connected in parallel with the non-linear resistor, adjustment of the tapping point enabling the overall time of operation of the circuit to be varied.

Filed: 1924-08-01
Abstract: 235,417. British Thomson-Houston Co., Ltd., (General Electric Co.). Aug. 1, 1924. Transmission conductor arrangements; switching-systems.-Relates to systems wherein a source 3 is connected to a network 1 through parallel feeders 2, 2<1> and to means for controlling from a single point the connections at both ends of the feeders for disconnecting and connecting same. A current-limiting means is connected to the station end of the feeder, when the latter is connected, and the current supplied to this means from the network operates a directional-power relav to disconnect the network end of the feeder, the arrangement enabling the use of a relay of ordinary construction. The Figure shows two feeders but any number may be employed, the arrangement of parts in each being identical. The feeder 2 is connected to main bus 3, auxiliary bus 4, and to the network 1 by switches 5, 6, 7, respectively. Switches 5. 6 have operating solenoids 13, 9 energized from a circuit 10 by means of switches 14, 11, respectively, and tripping solenoids 24, 17 energized by closure of switches 25, 18 respectively or by operation of the overload relays 19, 21. The switch 7 has a similar closing coil 28 and tripping solenoid 31 energized by the moving member 33 of the directional-power relay 32 when the network 1 supplies power to the feeder 2. The coil 28 is energized from the feeder 2 and is disconnected on closure of switch 7 by a switch 29. A transformer 26 is connected in the feeder 2 at its network end, and current-limiting means, which may be either a reactive or an ohmic resistance, is connected by means of switches 35, 36 with buses 3, 4. To remove the feeder 2<1>, the switch 5<1> is opened and switches 6', 36 closed thereby connecting the resistance 34 to the feeder 2 by way of bus 4. Reverse current now flows from the network 1 to the resistance 34 operating the directional-power relay 32<1> which opens the switch 7<1>. To reconnect the feeder 2<1>, the switch 6<1> is opened and switch 5<1> closed, thereby supplying current from bus 3 to the closing coil 28<1> of switch 7<1>. The procedure for removing feeder 2 is similar and ,any number of feeders may be removed by means of one resistance 34 though more than one could be used and more than one auxiliary bus.
