Title: Improvements in and relating to change-speed gears
IPC: B62M25/04
Filed: 1934-08-04
Abstract: 429,971. Controlling variable - speed gearing. DEHNE, 0., 25, Maistrasse, Munich, Germany. Aug. 4, 1934, No. 22792. Convention date, Aug. 5, 1933. [Class 80 (ii)] [See also Group XXXI] In gear-changing devices for motor-cycles and the like of the type in which the handle bars themselves are interconnected and serve as gear levers, a ratchet mechanism is interposed between the handle-bars and the actuating member of the variable-speed gear. In the form shown, the handle-bars 3, 4 are interconnected by toothed quadrants, and the bar 4 carries two ratchet teeth 14 pressed by springs 13 into engagement with notches in a slide 16, which is connected to the cable actuating the change-speed gear. The slide 16 carries a scale 18 passing below an opening 19 in the casing 2 to indicate which gear is engaged. The handle-bars tend to be returned to, and locked in, the central position shown by a spring 9 acting on a locking plate 8, which tends to compress the left-hand segment, which is made springy by the slot 12, so that it grips the other segment. The plate 8 is locked by a detent which has to be withdrawn by a manual control before gear change can be made. To prevent the handle-bars from returning to the mean position without being displaced sufficiently to effect gear change, the bar 4 carries a pawl 23 which is jammed by ratchet teeth 22 to prevent a return stroke unless it has been stroked quite past them. To prevent unauthorized use, the segment 4 may be locked by a pin 25 actuated by a key 26.

Title: Improvements in two stroke cycle internal combustion engines
IPC: F02B75/02
Filed: 1927-09-01
Abstract: 301,766. Edlin, G. S., and Stewart, H. H. Sept. 1, 1927. Two-stroke-cycle engines; cylinders, cooling, combustion chambers of, ports for, and igniters, arrangement in.-In engines wherein the combustion chamber is formed within a hollow piston 2, Fig. 7, reciprocating oppositely to the ordinary piston 11, the latter works in a fixed sleeve 12 over which also works the lower end of the piston 2. The fixed sleeve may be hollow, the interior being partitioned to provide for cooling-water circulation. The hollow piston works in a fixed cylinder 1, the upper part 16 forming a pre-compression pump for mixture. This is drawn into the pump through a valve 15 and after compression by the head of the hollow piston is delivered to the combustion chamber through corresponding ports in the cylinder and hollow piston; these ports may be arranged at the top of cylinder and piston, or as shown in Fig. 7, transfer passages 14 lead to inclined ports 14<a>, 20, which open at about the level cf the top of the sleeve 12. The pipe for the mixture to the pro-compression pump may be placed at the side of the cylinder as at 21 so that the hollow piston controls the admission to the chamber 16. The piston 2 controls exhaust ports in the sleeve 12, the hollow piston and fixed cylinder having corresponding exhaust ports. The sparking-plug may be placed in communication with the combustion chamber through a port in the sleeve used for mixture transfer, or as shown in Fig. 7 through a special port 22. To ensure ignition of the charge even when the engines is throttled for slow running the sparking-plug 29, Fig. 9, is mounted in a small auxiliary chamber 28 connected to the precompressioa pump 16 through a valved orifice 30. Mixture is admitted to the combustion chamber through the throttle valve 32 and ports 14, 13; whatever the position of the throttle valve a full charge will always be drawn into the pump and at the end of the power stroke the pressure in the pump chamber will be constant. As a consequence the auxiliary chamber 28 will receive a constant charge which displaces any products in the chamber through a port 32a in the hollow piston. At the end of the main compression stroke the charge in the chamber 28 is ignited and ignites the mixture in the main combustion chamber through one of the ports 13 which coincides with the end 31 of the chamber 28. To prevent contamination of the charge in the chamber 28 by gases from the main combustion space the chamber 28 may be formed with a restricted neck in which is placed the sparking-plug and which is cleared by the charge entering by the passage 30. The, volume of the chamber 16 may be equal to or less than the volume of the combustion chamber with the pistons at their widest distance apart.

Title: Phototropic information storage arrangement
IPC: G11C13/04
Filed: 1969-05-06
Abstract: 1,271,864. Bi-stable phototropic store. THOMSON C.S.F. 6 May, 1969 [10 May, 1968], No. 23146/69. Heading G4C. [Also in Division C4] A phototropic store comprises a phototropic plate 7 which is made transparent by electromagnetic radiation (e.g. light) from a source 4, a phototropic plate 8 which is made transparent by electromagnetic radiation from a source 1 and a unit 15 which can direct a radiation pulse from source 4 to plate 7. The plates 7 and 8 are normally opaque, but when a light pulse is passed from source 4 via unit 15, plate 7 becomes transparent, light from source 1 renders plate 8 transparent and light from source 4 keeps plate 7 transparent after the pulse from unit 15 has ceased. The store is returned to its original state by stopping the light from one of the sources which allows the plates to become opaque again. In one embodiment a separate light source can provide the pulse for rendering a third phototropic plate transparent (Fig. 4, not shown) to switch the store. In another embodiment (Fig. 5, not shown) data is stored rendering a small area of a phototropic unit transparent or an image stored by rendering a number of areas transparent, for example by using a cathode-ray screen as a source. In Fig. 6 (not shown) a small area of a storage plate can be selectively erased. In Figs. 7 and 8 (not shown) phototropic plates are backed by mirrors to become reflective (as opposed to transparent) on illumination by the appropriate light source. The phototropic material may be microcrystals of iron thionine compounds. The phototropic material may also be of the type which is normally transparent but goes opaque when irradiated by ultra violet light (e.g. spiro pyrane compounds or silver halide), becoming transparent again under the influence of heat, visible or infra-red radiation.

Title: Improvements in processes for the manufacture of ironchromium alloys
IPC: C21C7/00
Filed: 1933-08-22
Abstract: Low-carbon iron chromium alloys of the rustless iron or steel type are made by melting down rustless iron or steel scrap with or without low carbon steel scrap with slag forming material to produce a bath of molten alloy with a strongly oxidizing supernatant slag containing iron and chromium oxides and thereafter adding a non-carbonaceous exothermic reducing agent, e.g. a silicon-containing agent, preferably with lime to reduce the iron and chromium oxides, the chromium content of the melt being increased by the addition of chrome ore, e.g. chromite, all or the major portion of which is included in the original charge. The molten charge is initially superheated to a temperature of at least 3050 DEG  F. before the addition of the reducing material.  When the major portion of the chrome ore is added with the melt down charge, part of the ore up to 33 per cent of the total may be added during or subsequent to the melt down; the rest of the chrome ore up to 20 per cent is then added with the reducing agents.  The preparation of an alloy containing 0,08 per cent of carbon, 17 of chromium, 0,35 of silicon and 0,40 of manganese is referred to.  The iron-chromium alloys may also contain 0,1-8,0 per cent of copper, 0,1-35 of nickel, and 0,1-3,0 of tungsten, molybdenum and vanadium.

[Class 36] An insulator is resiliently secured upon a pin or support by a laterally compressible resilient member which has a tight frictional fit in a smooth cylindrical bore either in one of the parts to be secured together or in a member secured to one of these parts. The laterally compressible resilient member may be constituted by a portion of one of the parts to be connected or may consist of an intermediate member which is secured to or mounted on one of the parts. Fig. 1 shows an insulator a having a bore a<1> into which tightly fits the split and expanded end c of a resilient tubular supporting pin b. In a modified construction the pin is solid and the upper end is slotted longitudinally in cruciform manner. Alternatively, a split resilient tube may be forced into the insulator bore and the protruding end of the tube forced either over the end of the pin or into a socket formed in the end of the pin. In the latter construction the tube may be of rolled- or S-section. As shown in Fig. 17, a corrugated resilient sleeve p is inserted between the supporting pin i and the insulator. The corrugations may extend axially or circumferentially of the sleeve. In the embodiment shown in Fig. 23, a split sleeve h<1> is engaged over the pin i<1> and fits into a U -sectioned ring g<1> which is connected to a cylindrical extension a<111> of the insulator a by a split resilient tube f<1>.
