Abstract: 330,526. White, A. E., (Automotive Patent Holding Co.). March 7, 1929. Variable-speed gearing comprises an auxiliary two-speed gear B, Fig. 8, arranged between the main change and reverse gear A of a vehicle and the differential axle 13 and is characterized by flexible operative connections 52, 53 from the control of gear B to an additional shift bar 70, Fig. 5, in the control of gear A. The changes in gear A are effected by control lever 67 selectively engaging forks 62, 63 on bars 60. When fork 62 has been moved to the right of Fig. 5 to bring in direct drive, lever 67 may be moved laterally to engage fork 72 on bar 70, by sliding which gear 13 is operated. The bars 60 and 70 are interlocked by lugs 97, 98, Fig. 7, under a sliding plate 90. Bar 70 is combined with a lever 75 so as to actuate the cables 52, 53 in opposite directions. These cables, which act in tension, pass through tubes 81 to sockets 49, Figs. 2 and 4, in a lever 40. Screw means, not shown, are provided in the sockets, 49 to tension .the cables. The lever 40 pivots on an arbor 42 in gear case B and by means of lugs 50 engages a cranked pin 51 carried by a slide bar 35. Rocking of lever 40 slides bar 35 which carries a striker fork 37, Fig. 1, operating a sleeve clutch 25. The clutch 25 is in sliding connection with the shaft. 11 of the worm 12 which drives the differential, and is adapted to engage a clutch head 29 on shaft 10 for direct driving through shaft 2, Fig. 8. When clutch 25, Fig. 1, is moved to the right to engage a clutch 30, the worm 12 is driven at reduced speed through an eccentrically-supported hollow shaft 17 driven through pair 15, 16 from shaft 10, and driving through pair 20, 21.

Filed: 1953-03-23
Abstract: <PICT:0720836/IV (a)/1> <PICT:0720836/IV (a)/2> <PICT:0720836/IV (a)/3> A valve closure member for an electropneumatic valve is moulded of nylon having a hardness of 60 to 80 on the A.  Rockwell scale and comprises a moulded body 18 at one or each end of which is attached a sealing disc 26, or 27, of sheet nylon having a hardness of 50 to 100 on the Shore-A-Durometer Scale, the attachment being effected during the moulding operation by the moulding material passing through holes or peripheral notches 28 in the discs into channels of substantially semicircular cross-section in the ends of the mould to form retaining rings 30 unitary with the body 18.  The body 18 may be moulded round a valve actuating pin 26 or this may be fitted afterwards.  Lobes 32 moulded integrally with the body 18 form an abutment for a valve loading spring 24.

Title: Improvements in tube or like couplings
IPC: F16L37/24
Filed: 1954-03-18
Abstract: 745,996. Hose couplings. LEWYT CORPORATION. March 18, 1954 [April 27, 1953], No. 7956/54. Class 99(1). In a bayonet-type coupling, e.g. for the connection of a vacuum cleaner hose, wherein the socket member comprises a collar 31 having an outer end surface 32, the slot formed on the bore of the collar has a portion 34 inclined away from the surface 32 and there is a projection 37 adjacent the inner end of the slot. A spigot 16 provided with a pin 27, e.g. resiliently mounted on a spring 28, is inserted in and rotated relatively to the collar 31 and caused to advance into the collar by engagement of the pin with the surface 34, the pin being retained by the projection 37 at the inner end of the slot. As shown in Fig. 1, a number of bayonet slots have axial portions 33 connected by inclined portions 34 to shoulders 35 parallel to the end faces of the collar 31, the shoulders terminating in stops 36 parallel to the axis of the collar. As shown in Fig. 2, a rubber bushing 23 is mounted on an enlarged portion of the spigot 16 and has an inward flange 24 bearing against a shoulder 21 of the spigot, and an internal flange 25 engaging in a channel 22 of the spigot. The bushing has a lip 25<SP>1</SP> flexibly supported by a portion 26 of reduced thickness. In assembly, Fig. 3, the pins 27 are engaged in the slots 33 and the lip 25<SP>1</SP> contacts the surface 32, axial movement and subsequent rotational movement of the spigot to force the pins 27 over the projections 37 causing the spigot to pass through a grommet 39 in a wall 40 and the lip 25<SP>1</SP> to be compressed and curl over to engage the outer surface of the spigot. The hose 5, Fig. 2, is of rubber and may incorporate a spring wire reinforcement and is forced over a tube 12 having an end overlapping the adjacent end of the hose as at 13, and teeth or tongues 14 which engage against or become indented in the surface of the hose. The end of the hose is bound with a layer of protecting tape 11 and enclosed in a rubber or metal sleeve 15. The spigot 16 is formed with channels 18 in one of which is disposed packing ring 19, the other channel being engaged by a channel 20 in the tube 12 to provide for relative rotational movement between the spigot and the tube.

Abstract: 1278742 Colour television camera SONY CORP 19 Feb 1970 [22 Feb 1969] 8060/70 Heading H4F A white balance control system for a colour television camera 1, Fig. 1, comprises gain control circuits 3a and 3b in the red and blue signal paths, the control signals for which are derived from subtraction circuits 5a and 5b in which the red and blue signals are respectively subtracted from the green signal and any difference is fed to a memory circuit which maintains the optimum gains in circuits 3a and 3b for white balance. Ganged switches S1 and S2 are only closed when a white object is televised, since for a white object the red, green and blue signals should be equal for correct white balance. The subtraction circuits include integration circuits. The memory circuits preferably comprise a memory capacitor and a field effect transistor (Fig. 2, not shown). In a second embodiment, Fig. 3, the colour difference signals R - Y and B - Y are applied via clamp circuits 14a and 14b and integration circuits 15a and 15b to memory circuits 16a and 16b when a white object is being televised, ganged switches S3 and S4 being then closed. The clamp circuits are provided for eliminating a level change resulting from a change of the dark current in the image pick-up tube, and are gated in synchronism with the horizontal sync. pulses.

Abstract: 1490147 Keyboards ROCKWELL INTERNATIONAL CORP 1 March 1976 [23 June 1975] 08109/76 Heading G4H [Also in Division H3] In a circuit for sensing the state of a switch 82 the opened or closed state of which provides a first reference voltage, such as ground, or a supply voltage - V LED  to a node 78 which is connected through an impedance 70 to the first reference, during timing #3 a node 80 is precharged to a second reference voltage while a switch 68, interconnecting nodes 78 and 80, is off, in a sensing interval #1 the switch 68 is rendered capable of conduction and the change or not of the voltage at node 80 represents the state of the switch 82 is opened or closed corresponding to the node 78 having the first reference value or the supply voltage value. During the sensing interval #1 a node 79 is precharged to - V LED  via FET 72 to render FET 68 capable of conduction and a strobe driver FET 51 is also controlled so as to be conductive. When the switch 82 is open FET 68 conducts to change the output 80 to the first reference voltage whereas when switch 82 is closed FET 68 remains off so that output 80 remains at the precharged second reference voltage. During the precharging of node 80 during #3 FET 76 is turned on to discharge the node 79 so that FET 68 is nonconductive. The circuit can be for sensing the states of the switches on a keyboard of a calculator where the keyboard 81 and an associated LED display 60 are driven from the calculator chip. A detailed description of the LED display and associated strobe driver and digit select FET's is disclosed in Specification 1,490,146.
