Title: Improvements in or relating to controls for internal combustion engines
IPC: F02N3/00
Filed: 1945-04-25
Abstract: 591,675. Regulating. HENRY, H. P. April 25, 1945, No. 10347. [Classes 7 (ii) and 7 (vi)] In an outboard motor the tiller lever 30 also controls the fuel throttle, air choke, ignition timing, clutch and exhaust cutout over the whole range from stop to full speed. As applied to a motor comprising a cylinder 10, flywheel 12, crankcase 11, and a housing 14 for the driving transmission shaft mounted in a sleeve 15 attached to the boat by a clamp 17, the lever 30 rotates a shaft- 27 journalled in brackets 23, 24. On the shaft are fixed a cam 31 actuating the clutch by means of levers 40 and 42, an arm 32 controlling the flywheel magneto timing through a rod 43, an arm 33 connected by a rod 45 to the exhaust cut-out on the expansion chamber 20, a cam 34 controlling the fuel throttle 51 and petrol tank air-vent 53 through a lever 50, and an arm 35 connected to the air choke 57. The bracket 24 carries a flanged quadrant 25 adjacent the lever 30 divided into stop, starting and driving ranges by the stops 60, 61 engaging a detent 62, Fig. 4, carried by a spring loaded handle 65. When lever 30 is in the vertical, i.e., stop, position the air choke 57, fuel throttle 51 and petrol tank air-vent 53 are closed to allow the engine to be detached from the boat without spilling petrol. When starting, the handle 65 is depressed to allow detent 62 to clear the stop 60 and the lever 30 is moved into the appropriateposition, inscribed on the quadrant 26 between stops 60, 61 for a "cold," "warm" or "hot" start. In this position the air-vent 53 is opened, the fuel throttle and air choke adjusted to give the requisite starting mixture, the exhaust cut-out 46 is opened allowing the exhaust to escape to the air instead of beneath the water, and the ignition is suitably retarded. The engine is started by means of a cord wound round the pulley 13 and after starting the lever is moved past the stop 61 into the idling position, which closes the exhaust cut-out. Further motion of the lever downwards operates the clutch to transmit the drive to the propeller, and progressively opens the fuel throttle 51 and air choke 57 until full speed is reached with the lever horizontal. A spring-pressed plunger returns the lever to the idling position if it is released in the driving range. The engine may be enclosed in a stream-lined casing, lever 30 projecting through a slot or being fixed on the end of the shaft 27.

Title: Improvements relating to electric circuit breakers
IPC: H01H9/36
Filed: 1928-04-05
Abstract: 288,326. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Slepian, J.). April 6, 1927, [Convention date]. Arc-rupturing devices of the general character described in Specification 258,234 have in place of the perforated deionizing plates of the earlier Specification a number of solid conducting plates disposed transversely to the arc so as to divide the arc into a series of small parts; the arc is also driven round an endless track over the surfaces of the plates till it is extinguished. The invention is specially applicable to alternating currents, the cool surfaces of the plates preventing re-formation of the arc after the zero of the A.C. cycle has been passed. Fig. 1 shows the invention applied to a circuit-breaker having a main bridging contact 3, auxiliary contacts 15 which open after the main contact, and arcing contacts 8, 14 which open still later. After the main contact 3 has opened current flows through an arm 6 contacts 14, 8 of blow out coil 11 and when the contacts 14, 8 have separated the arc is transferred to the horn plates 22, 23 and is driven upwards by the magnetic field formed between pole pieces 25 of the magnet 11. It then encounters the conducting plates which in the example shown consist of two series 31, 32, of nine plates each, of the shape shown in Fig. 3, placed between three series 62, 63, 64, of plates of the shape shown in Fig. 4. The arc is driven up the V-shaped passage 36 formed by the lower ends of the plates, the effect of the V-shape being to constrict the arc and to raise the current density so as to permit the smooth transference of the are on to the plates themselves. Coils 45, 49, 49, 54 are arranged above the series of short plates 62, 63, 64 and are so connected that, as the arc continues to rise up the plates 31, 32 these coils are placed in circuit with it and produce a magnetic field that is radial to the centres 37 of the plates 31, 32 and drives the arc round and round the dotted lines shown in Fig. 3 till it is extinguished. The theoretical considerations governing the size and number of the plates, their distance apart and the shape of the V passages 36 are discussed, but generally speaking, the plates may conveniently be <1>/16th of an inch thick and <1>/16th of an inch apart and the voltage between adjacent plates should never exceed 300 volts, the voltage required to produce a brush discharge. To secure a uniform distribution of potential along the plates, an electrostatic screen of conducting plates 70 - - 75 surrounds the structure. A practical construction of blow-out is also described (Figs. 5 - - 7 not shown). In this construction, pole pieces attached to the poles 25, extend upwards so as to embrace the arc-chute. Side walls of soapstone are also provided having grooves which prevent the formation of a continuous conducting coating on the soapstone due to condensation of metal vapour from the arc.

Filed: 1974-03-08
Abstract: 1453391 Surface wave devices THOMSONCSF 8 March 1974 [9 March 1973] 10603/74 Heading H3U An acoustic surface wave transmission device includes input and output electro-acoustic transducers 2, 4 respectively generating and receiving surface acoustic waves in a surface of a piezoelectric substrate 1, at least one grating reflecting the surface waves between the two transducers, and a thin, preferably photoconductive, layer 5 located between the grating and the receiving transducer 4 so as to allow interaction between carriers generated within the layer 5, e.g. in response to incident light, and the surface waves. This interaction, constituting a co-called zero-electric-field acoustoelectric effect, results in selective attenuation of the surface wave. Various systems employing this effect are described. As shown in Fig. 3, a non-dispersive band-pass filter includes two identical parallel reflective gratings 31, 32 of progressively increasing spacings, a photoconductive strip 5 being situated between and parallel to the gratings 31, 32. A movable mask 7 with one or more opaque areas 70 allows all but a selected portion of the strip 5 to be illuminated, the surface wave being transmitted across the strip 5 only where the latter is masked by area 70. The length of the area 70 determines the pass frequency bandwidth, and the centre frequency of the pass band is adjusted by moving the mask 7. To vary the bandwidth the extent of area 70 can be varied. Suitable shaping of the area 70 or of the strip 5 results in a "weighted" band-pass filter. The provision of a plurality of opaque areas on the mask, or of a plurality of separate photoconductive layers (5l-5w) Fig. 5 (not shown) results in an "interdigital" filter. A non-dispersive variable delay line is formed by providing two parallel gratings with regular spacings and using a movable mask with a single opaque area. Alternatively the mask may remain stationary and include a plurality of spaced opaque areas in order to provide an amplitude-coded line. A non-dispersive delay line having intermediate tap switching is provided by a device having a single evenly-spaced grating (3) Fig. 7 (not shown) and a plurality of output transducers (4l-4n) arrayed along the photoconductive strip (5). Programmable switching is then obtained by altering the positions of masking areas. The piezoelectric substrate 1 (Fig. 3) preferably comprises Y-cut LiNbO 3 , the lines of the grating(s) 31, 32 being engraved. The layer 5 is of CdS less than 0À5 Á thick.
