Title: Improvements in or relating to shaft couplings
IPC: F16D1/12
Filed: 1922-10-05
Abstract: 206,327. Guiterman & Co., Ltd., S., Tate, G. E., and Monkhouse, F. O. Oct. 5, 1922. Shaft couplings are adapted to adjust two shafts positively through small angles by means of two cylinders a, d having rings of equallyspaced holes g, i respectively, the two rings differing as to the number of holes. An angular displacement of say 5‹ brings a different pair of holes into coincidence, and a set screw l is passed through the outer hole and screwed into the inner. The screws and coinciding pairs may be duplicated. The member a is secured directly to one shaft, and the member d may be connected to the other shaft through means permitting bending at the coupling. Thus a boss q secured to the second shaft by a pin s may have ribs p interpenetrating internal ribs m upon the cylinder d. Cushioning means h may be arranged between the two sets of ribs. This adjustable cushioned universal arangement is specially adapted for timing the ignition of internal-combustion engines.

Patent GB-775761-A (GB)
Title: Apparatus and method for the application of liquid coating compositions
IPC: B05B13/04
Filed: 1953-10-05
Abstract: <PICT:0775761/III/1> <PICT:0775761/III/2> An apparatus for treating the surface of an article 26 with a liquid, e.g. paint, comprises a conveyer 12 for advancing the article along a rectilinear path through a housing 10, a nozzle 27 or 28, means for delivering paint under pressure from a supply 61 to the nozzle to cause it to be ejected in a solid stream therefrom, and means for moving the nozzle 27 or 28 in a path contained in a plane inclined to a plane normal to the rectilinear path.  The housing 10 is divided into a tempering zone A, a coating zone B, a zone C where the articles 26 are subjected to a controlled atmosphere, e.g. by steam pipes 87, or by cooling, to facilitate removal of surplus paint from the articles, and a drying zone D.  The zone A may be heated, e.g. by steam pipes 11a, or cooled, to condition the articles to the painting operation. Paint is delivered in jets from side nozzles 27, 28 mounted on arms 30, 35 rotating respectively about hollow shafts 31, 36, a bottom nozzle 29 on an arm 43 rotating about a hollow shaft 40, and fixed top nozzles 59, 60.  The arms 30, 35, 43 are radially adjustable on their shafts, and the shafts are rotated through sprockets and chains as 49, 50, 57 from a shaft 45 driven by a motor 44.  A pump 63 delivers paint from a tank 61 through a filter 66 and a heat exchanger 67 (for cooling) and thence by pipes 70, 71, 72 to distributer pipes 73, 74, 42, 38 leading respectively to nozzles 59 and 60, 27, 29, 28.  If the paint is to be preheated, the exchanger 67 is by-passed and a heat exchanger 76 employed, or some of the paint may go to the exchanger 76, the rest passing through the exchanger 67, which is not, however, used for cooling.  Regulation of valves 85, 86 enables thinner from a tank 62 to be mixed with the paint, or used alone, and paint and/or thinner collecting in the sump 80 after coating may be returned to either tank 61 or 62 by regulating valves 81, 82.  Air is forced through zones C, D by fans 15, 24 communicating with vertical ducts 13, 18, 20 having openings 14, 19, 21 respectively. To facilitate dripping of paint off the articles 26 in zone C, thinner from a tank 90 may be atomized at 88 and added to the air stream, the air and thinner leaving by a pipe 23.  Various modifications are mentioned.  The nozzle 29 may be replaced by a stationary nozzle or nozzles, or the nozzles 27, 28 by nozzles which oscillate at the end of an arm to describe an arc in a vertical plane at each side of the housing, Fig. 5, not shown.  In this case the lower nozzle corresponding to 29 oscillates in an arcuate path in a horizontal plane.  In another modification, a nozzle at each side of the housing 10 is mounted on an endless chain arranged in a vertical plane and passing at each end over sprockets carried by horizontal shafts at the top and bottom of the tunnel.  By this arrangement, the side nozzles are reciprocated up and down the article to be coated.

Title: Improvements in or relating to articles consisting of inorganic, insulating, heat-resistant material comprising an electrically conductive layer
IPC: H01B1/08
Filed: 1952-10-31
Abstract: Articles of inorganic, insulating, heat-resistant material, i.e. material which does not melt or soften at temperatures below 300 DEG C., are provided with electrically conductive coatings comprising tin oxide and a phosphorus oxide, by applying a hydrolysable tin salt, to which a phosphorus compound has been added, to articles heated to at least 300 DEG  C., e.g. by vaporization of a mixture of a volatile tin salt and a phosphorus compound from a solution, by dipping the articles into such a solution, or by spraying the latter on the heated articles.  The tin salt may be a halide and is preferably tin tetrachloride; as phosphorus compounds the trichloride, pentachloride, oxychloride or other halides, phosphates, e.g. ammonium phosphate or phosphoric esters, e.g. tricresyl phosphate, may be used, if soluble in the tin salt solution, the amount being generally between 0.1 and 25 per cent by weight of that of the tin salt. The solvent is preferably an organic liquid, e.g. carbon tetrachloride, benzene or ethyl acetate; but aqueous solutions containing hydrochloric acid may be used.  The invention may be applied to domestic articles such as grills and toasters, to laboratory receptacles such as flasks and fractionating columns, to cathoderay tubes and windows of electrical measuring apparatus for carrying off static charges, to electrical resistances, and to glass plates capable of being heated, especially windscreens for motor vehicles and aircraft.  The coated surface may be protected by a silicone lacquer, or in the case of a heatable glass window, by a second glass plate, in which case a layer of transparent plastic material may be sandwiched between the two plates. Current supply contacts may be provided by vaporizing or burning metal on to the conductive layers.  Specifications 632,227 and 639,561, [both in Group XI], are referred to.
Patent GB-1044396-A (GB)
Title: Voice operated gain adjusting device
IPC: H04B3/06
Filed: 1964-07-03
Abstract: 1,044,396. Automatic volume control circuits. STANDARD TELEPHONES AND CABLES Ltd. July 3, 1964 [July 5, 1963], No. 27561/64. Heading H4R. A voice-controlled automatic gain adjusting device, Fig. 1, comprises a main amplifier having separate gain increase and gain decrease circuits controlled to vary the gain in either direction from a preset idle gain position. The gain-controlling circuits include photo-sensitive resistors in series or shunt with the speech path, the value of the resistors being controlled via lamps which are fed with current through gate circuits Q205, Q206 and Q208. Gate Q206 is rendered conductive when an input signal is present on the line and enables gates Q205 and Q208. Gate Q205 is fed with the output of a speech recognition circuit and feeds current to the gain increaser lamp when speech is detected. Gate Q208 is fed with the main amplifier output and feeds current to the gain decreaser lamp when the output level exceeds a predetermined value. In addition signals likely to overload the output stage result in transistor Q210 being switched on to cause the feed of current to the gain decreaser lamp, the switching signal being fed through a non-linear resistor in order to provide a speed of operation proportional to the degree of overload. The normal control of the lamp current is relatively slow due to the presence of capacitors in the collector circuits of transistors Q209 and Q210. The signal feed to the control circuits is via a centre slicer comprising diodes CR101 and CR103 whose bias is dependent on the circuit output so that only the peaks of the signal are fed to the control circuits. The centre slicer circuit is arranged to have a slow recovery after a fall in speech level so that the gain increase is delayed. The speech recognition circuit, the output of which feeds the gain increaser gate, comprises a 1À2 kc. band-pass filter, an envelope detector, and a 7.c.p.s. tuned amplifier so that only signals having a frequency distribution and a modulation similar to those of speech are passed to the rectifier to provide the gain increaser control signal. A complete circuit diagram of the equipment is described, Figs. 2 and 3 (not shown).
