Title: Rotary piston internal combustion engine
IPC: F02P9/00
Filed: 1972-10-03
Abstract: 1376515 Rotary I C engines NISSAN MOTOR CO Ltd 3 Oct 1972 [7 Oct 1971]  45537/72 Headings F1B and F1F A trochoidal-type rotary piston internal combustion engine has a sparking plug 25 controlled by an ignition system such that, during deceleration of the shaft rotation, the plug 25 alternately fires and misfires. The ignition system comprises a D.C. source 30 which is connected via switch 31 with ignition coils 32, 33 having primary and secondary windings 35, 36 and 38, 39. The primary windings 35, 36 are connected to breakers 45, 46 operated by cam 48 on a shaft 49 which rotates at half the speed of engine drive shaft 16. Condensers 56, 57 are connected in parallel with breakers 45, 46. Secondary coils 38, 39 are connected to rotary electrodes 41, 42 of a distributer 43 which also has stationary electrodes 61, 62 connected to plug 25 and earth respectively. Inserted between switch 31 and coil 33 is a further switch 65 operated by rod 69 attached to a diaphragm of a unit 68 communicating with the engine inlet manifold 66. If engine 10 is used in a vehicle, then deceleration increases the vacuum in manifold 66 and rod 69 moves to open switch 65. Thus opening of breaker 46 by cam 48 does not produce firing of plug 25 which thus alternately fires and misfires compared with normal operation. Instead of a single switch 65 being used, two parallel switches can be employed, one functioning like switch 65 and the other being controlled by a switch governed by a magneto driven by the main shaft of the engine Fig. 2 (not shown). In this case the vehicle must be running at a predetermined high speed, as well as decelerating, if the desired misfiring is to be effected. A single ignition coil and rotary electrode may be used Fig. 3 (not shown).

Abstract: 1,253,605. Conjugate Optical fibres. POLYOPTICS Inc. 17 Sept., 1969, No. 45773/69. Headings B5A and B5B. Optical fibres are made by extruding a light transmissive material capable of being drawn inside a preformed supported jacket, also capable of being drawn and having an index of refraction lower than that of the light transmissive material, and then stretching the thus formed composite body, the method being such that each section of said body is contiguous with the same section of said jacket at substantially all times subsequent to contact on extrusion. The light transmissive material may be extruded in fluid form through one end of the jacket by means of an extrusion tube which moves with respect to the jacket from one end of the jacket to the other, while the extrusion takes place. Gas may be withdrawn from the .interior of the jacket during extrusion. The materials used for the inner body and the jacket may be thermoplastics materials, preferably poly-methyl-methacrylate with an index of refraction of 1À5 for the jacket and polystyrene with an index of refraction of 1À6 and a lower softening point than that of the jacket material for the inner body. Prior to extrusion the light transmissive material may be stored in a vacuum chamber at an absolute pressure of less than 1 mm. of mercury for at least 4 hours and heated to extrusion temperature in the absence of free oxygen. Apparatus as shown in Figs. 1 and 3 includes a conventional hopper 30 and extruder 12 with provision for maintaining an inert atmosphere in the extruder; a tube 26 through which the fluid light transmissive material is extruded on to the inside of the preformed jacket 52 which is supported by a rigid metal support tube 56; driving means 66 to move stopper 64 and slider block 48 to the left, thus progressively withdrawing the extrusion tube 26 as the jacket 52 is filled; and a conduit 60 to apply a vacuum to exclude gases from the interior of tube 56.

Filed: 1974-10-23
Abstract: 1485014 Automatic control ROBERT BOSCH GmbH 23 Oct 1974 [25 Oct 1973] 45806/74 Heading G3N Current flow between a motor and a battery on a road vehicle is regulated during driving and braking in accordance with a demanded current value and the output of a wheel slip measuring arrangement including a device for sensing the speed of a driven wheel on the vehicle. As shown in Fig. 1, road wheels 10, 11 are driven through a differential 16 by a motor 14  supplied from a battery 23. The motor may be  series or shunt wound and supplies by pulses, or asynchronous and supplied by A.C., by way of a controller 24 including a current regulator 27, Fig. 2. The controller receives demand signals from drive and brake pedals 25, 26 connected to potentiometer 33, 32, and an indication of road wheel speed from a tachogenerator 17 including a toothed gear 18 and a receiver 19. A similar arrangement 20 supplies a signal indicative of the speed of non-driving wheels 12, 13. The tachos 20, 17 are connected through frequency-to-voltage converters 37, 38 to a differential amplifier 36, a non-zero output from which indicates wheel slip during acceleration or braking. If the slip exceeds say 2 or 5%, a voltage is transmitted through an appropriate one of a pair of diodes 34, 35 to be summed with a respective demand signal at summer 30 or 31, to produce a desired current value 28, 29 for the regulator 27. During braking, the motor 14 operates as a generator to charge the battery 23 at a maximum rate, the braking effect being supplemented mechanically if necessary. In another embodiment, Fig. 3 (not shown), potentiometers 32, 33 are connected to a single summing point feeding a single input to the regulator 27 by way of an integrating operational amplifier. A further embodiment, Fig. 5 (not shown), uses only one tachogenerator 17, the output of which is converted to a voltage which is differentiated and then compared with threshold devices so as to detect sudden changes in acceleration. Both speed and acceleration responsive devices may be used together. A PI regulator may be connected between the threshold devices and the summing point, Fig. 6 (not shown).

The semiconductive materials may be Si, Se, or the chalkogenides of Cd or Zn. The binder may be an epoxy, polyester, silicone or alkyd resin, a resin of polyisocyanates and polyhydroxy compounds, cellulose acetate, acetobutyrate or ester, low melting glasses or enamels. If more than one layer of binder containing a fluorescent dyestuff is used, as exemplified, then they are arranged so that the dyestuff having its absorption maxima at the longest wavelength is next to the semi-conductor. It is also advantageous that the layers are arranged such that the refractive indices of the binders increases towards the semi-conductor lays. A multilayer element is preferably built up either by applying each layer freshly to the element after the preceding layer has hardened or by forming individual layers separately and then combining the layer with the preceding layer by using its binder as an adhesive.
