Patent GB-268322-A (GB)
Title: Improvements in sewing machines
IPC: D05B3/02
Filed: 1927-03-11
Abstract: 268,322. Union Special-Maschinenfabrik Ges. March 25, 1926, [Convention date]. Hat-sewing machines; braids, attaching; loop stitching; threads, controlling otherwise than in stitch fonning.-In overedge stitching, such as in binding hat brims, a variable width of seam is obtained by laying the threads over a displaceable finger or over a stiff member, such as a wire, which is to be secured to the work and is held at laterally variable distances from the seam line and needle. In a machine of known general type, having an overedge threaded looper 4, a stitch-finger 5 is mounted on a lever 7 which is adjustable by a rod 8 and crank 9, 11 operated manually, or by a suitable cam &c. device to vary the distance of the finger from the needle 3. When a wire is to be attached to a hat-brim, a notch 17 is provided in the lever into which the wire is fitted and the stitch-finger may then be dispensed with or may serve only as a regulator. A device for varying the pull-off of the looperthread in accordance with variation in the width of seam comprises a loop 21 mounted on the lever 9, 11 and displaced therewith so as to vary the amount of lost motion relative to a loop 20 carried by the needle-actuating lever 22. The tension device 23 is at the same time controlled by a plunger 29 engaged by a curved plate 27 carried on an arm 35 on the shaft 10 of the lever 9, 11. In binding a hat-brim, braid 14 is secured by a seam which passes over a wire 15 held at desired variable distances from the edge 12.

Title: Improvements relating to variable resistors
Inventor: MASH DEREK HUBERT
IPC: H01L31/16
Filed: 1960-02-26
Abstract: 921,262. Photo-electric devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 6, 1961 [Feb. 26, 1960], No. 6864/60. Class 40 (3). [Also in Group XXXVI] A variable resistor comprises a non-uniform light filter placed between a constant light source and a photo-conductive material so that the resistance between two terminals connected to the material is variable by relative movement of the filter. In Fig. 1, an opaque screen 5 with a hole or slit 6 is placed between electric light source 2 and a photo-conductive body 5 with terminals 8. A cylinder 9 consists of glass with a photographic emulsion coating of varying density situated opposite hole 6; cylinder 9 may be rotated by knob 10 to vary the intensity of light falling on body 7 and thus its resistance. The photo-conductive material may consist of selenium or cadmium sulphide, activated if desired with copper or chlorine, and may be a thin film, a sintered powder or a single crystal. In an alternative arrangement relative rotation of two polarized discs is used instead of the variable density emulsion. Two bodies of photo-conductive material may be used, each associated with a hole in the screen 5 and the associated filter element, the arrangement being such that turning knob 10 increases the resistance of one body while decreasing the resistance of the other thereby forming a potentiometer. Reference has been directed by the Comptroller to Specification 879,949.

Title: The manufacture of acetylene and chlorinated hydro-carbons
IPC: C07C11/24
Filed: 1959-03-02
Abstract: Acetylene and chlorinated hydrocarbons are produced when chlorine is reacted with an aliphatic hydrocarbon and/or a halogenated aliphatic hydrocarbon at above 700 DEG C.  The reactants are preferably introduced into the reaction zone at a velocity above 10 metres per second and a diluent may be added which may be inert or react, and if it reacts may produce or absorb chlorine. Sub-atmospheric pressure may be used and a flame may be formed. By-products may be reacted further with chlorine in a second stage or recycled to the primary reaction.  The reactants may be sprayed with water to cool them and absorb hydrogen chloride.  In Examples (1) methane is reacted with chlorine to give acetylene, methyl chloride and vinyl chloride; (2) ethylene, hydrogen chloride and chlorine give acetylene, vinyl chloride, 1:1- and 1:2-dichloroethylene; (3) cracked gas (ethylene, propylene, butylene, methane and ethane) with chlorine and tetrachloroethane give acetylene, vinyl chloride, dichloroethylene and perchloroethylene with small amounts of hexachlorobutadiene; (4) ethylene and chlorine give acetylene and vinyl chloride; (5) ethylene, vinyl chloride, methyl chloride and chlorine give acetylene, vinyl chloride, methyl chloride and dichloroethylene; the vinyl and methyl chlorides are separated and recycled; (6) ethylene and chlorine give vinyl chloride, methyl chloride and acetylene and hydrogen chloride which may be reacted to give vinyl chloride; (7) methane, carbon tetrachloride and chlorine give acetylene, methyl chloride and dichloroethylene; (8) ethyl chloride and chlorine give acetylene, vinyl chloride, ethylene and dichloroethylene; (9) ethyl chloride, ethylene chloride and chlorine give acetylene, vinyl chloride and ethylene.

Abstract: 1,177,277. Asynchronous generator. S. CUCCHI. 15 Feb., 1967 [19 Feb., 1966], No. 7278/67. Heading H2A.  A capacitor excited asynchronous induction generator has parts of the stator winding connected in series with a capacitor so that when the squirrel-cage rotor rotates an output is obtained across the remainder of the stator winding parts. In the single-phase generator shown, capacitor 10 is connected in series with the whole of two phase windings 15, 16; 14, 13 and the output appears across the third phase winding 11, 12. For 3-phase generation the connections between the phase winding parts are removed and half windings (12<SP>1</SP>, 14<SP>1</SP>, 16<SP>1</SP>) are connected in series with the capacitor so that a 3-phase output is obtained across the other halves of the phase windings ( 11<SP>1</SP>, 13<SP>1</SP>, 15<SP>1</SP>), which are connected in star, Fig. 3 (not shown), or delta. In both embodiments one of the part windings is reversed when connected in series with the capacitor.

Abstract: 691,228. Preventing skids. AUTOSTABLE SOC. ANON. April 2, 1951 [March 31, 1950], No. 7566/51. Class 108 (ii). In an anti-skid device for road vehicles in which at least one inertia body is movable relatively to the vehicle from a normal position against the action of springs, at least two springs of different strength are actuated progressively according to the magnitude of the skid. In Fig. 4, the inertia weight 2 is slidably mounted between weaker springs 11 in a guide tube 10. The tube 10 is slidably mounted between stronger springs 12 in a main guide tube 1. In a modification, Fig. 1 (not shown), the tube 10 is dispensed with and the springs 11, 12 are separated by abutment discs. In a further construction, Fig. 2 (not shown), each stronger spring is mounted concentrically within the respective weaker spring which is of conical formation. The stronger spring is shorter than the weaker spring so that its end is not initially in engagement with the weight 2. In the construction shown in Fig. 5, a single weaker spring 8 is mounted between two weights 2, 2<1>, which are also acted on by respective stronger springs 9. Ball bearings 14, are mounted between the weights 2, 2<1>, and a rod 13 and tube 1. The rod 13 may be mounted resiliently at its ends or may be flexible, and the weights may have a clearance relative to the tube 1, so as to provide for damping movements of the vehicle in a vertical direction. Alternatively the ends of the tube 1 may be resiliently mounted on the vehicle frame. The device may be partially filled with oil.
