Patent GB-746126-A (GB)
Title: Improvements relating to electrical systems for automatically dimming automobile headlamps
IPC: B60Q1/14
Filed: 1954-02-19
Abstract: 746,126. Photo-electric headlamp dimming systems. GENERAL MOTORS CORPORATION. Feb. 19, 1954 [March 5, 1953], No. 4890/54. Addition to 712,740. Class 40 (3). The invention is an improvement in the headlamp dimming system claimed in the parent Specification, in which a photo-electric cell responsive to light from the headlamps of an oncoming vehicle developed a voltage across means in the grid circuit of an amplifier tube to control the dimming switch and in which part of the means was shunted out to increase the amplifier sensitivity when the headlamps were dimmed. According to the present invention a manual over-riding switch is provided which does not affect the condition of the automatic circuit. As shown, light from the headlamps of the oncoming vehicle increases the current in the photo-sensitive device 50 developing a voltage across series resistors 54, 56, 58 of which 56 and 58 are, in the undimmed condition, shortcircuited. The current in amplifier tube 40 decreases until relay 68 is no longer able to hold its contact against the action of spring 46. This contact completes the circuit of a further relay 14 through a foot switch 6, normally in the position shown, and the overriding switch 84 which is closed for automatic operation of the system, to change the headlamps from "light" to " dim." At the same time the short-circuit is removed from sections 58 and 56 of the grid resistors of tube 40 increasing the sensitivity of the amplifier so that, if the oncoming vehicle also dims its headlamps, the circuit does not immediately return to "bright." The overriding switch 84 is placed in series with the foot switch 6 and enables relay 14 to be de-energized restoring the headlamps to " bright."

Patent GB-568598-A (GB)
Title: Improvements in or relating to coated fabrics suitable for use in the manufacture ofaircraft
IPC: D06N3/02
Filed: 1943-03-29
Abstract: Pliable coated fabrics having a potential shrinkage and suitable for covering aircraft parts, drums and cinema screens are made by wetting the fabric with water, allowing it to shrink while wet, applying thereto a cellulose derivative aqueous emulsion of the water-in-oil type, drying the coated fabric, and stretching the fabric to its original dry width during or after drying. Alternatively, the emulsion may be applied to a dry, unshrunken fabric which is allowed to shrink while drying the emulsion and subsequently stretched to its original dry width.  The stretching minutely fractures the dried coating.  The emulsion consists of drops of water dispersed in a solution of the cellulose derivative in a volatile solvent and contains a proportion of plasticiser which is low in relation to the cellulose derivative.  When applied to a wetted fabric it is forced, e.g. by a doctor knife into the interstices of the wet fabric.  In use, the coated fabric is fitted or stretched over an aircraft part &c., and coated by brushing or spraying with a solution of a cellulose derivative in an organic solvent which dissolves the minutely fractured coating and shrinks the fabric.  The emulsion may comprise cellulose nitrate dibutyl phthalate, castor oil, pigment, methyl ethyl ketone, and water, or cellulose aceto-butyrate or aceto-propionate triphenyl phosphate, methyl ethyl ketone, and water. A fabric coated with the emulsion, dried, and secured to an air frame is shrunk and tautened by applying a number of coats of a composition comprising cellulose nitrate, dibutyl phthalate, castor oil, pigment, butyl and ethyl alcohol, butyl and ethyl acetate, petroleum naphtha. The dried emulsion coating may be polished by hot-calendering.  The fabrics with the dried emulsion coating may also be used in tape form to cover seams or for reinforcing or finishing purposes on aircraft, being applied over a brushed-on coating of "dope."

Abstract: 1,090,092. Boring machine details. GOSUDARSTVENNY NOVOSIBIRSKY ZAVOID TYAZHELIKH STANKOV I KRUPNIKH GIDROPRESSOV. Feb. 5, 1965, No. 5062/65. Heading B3C. A boring machine for producing tapered or profiled bores comprises a bed 1, Fig. 1, a slide 2, which carries a column 3 on which is mounted a head stock 4 having a boring head 5, and a base 11 for a non-rotating workpiece 12. A template 8 is mounted on bed 1 and co-operates with a follower 26 mounted on slide 2. Head 5 is rotated by an electric motor 13 through gears 14-17, and slide 2 is fed by an electric motor 19, gears 20-24, and a rack 25. The linear motion of follower 26 is transformed into an angular motion of a synchro transmitter 30 through gears 27-29. If the rotor of a synchrorepeater 31 does not rotate, the input voltage of a phase sensitive amplifier 32 changes by an electric angle equal to the geometric angle of the transmitter 30, and D.C. voltage is supplied through an amplifier 33 to motor 34. The latter rotates a screw 38 through gears 39-42, the screw being connected to synchrorepeater 31 through gears 36 and 37, and also to a nut 43, carried by a spindle 35, so that the latter is moved axially. A rack 44 connected to the spindle rotates a gear nut 49 through gears 46-48, and the toolholder is adjusted radially. This adjustment can also be made manually by bringing an auxiliary transmitter 57 into the system, which is operated by rotating a handle 56. In a modification the workpiece moves axially instead of the boring head. When a tapered bore is to be produced a template 50, Fig. 3, is provided whose angle α can be varied by an electric motor 51 which rotates a screw 54 to co-operate with a nut 55.
