Abstract: 738,726. Valves. TEDDINGTON AIRCRAFT CONTROLS, Ltd., [formerly TEDDINGTON CONTROLS, Ltd.]. Dec. 18, 1953, No. 35328/53. Class 135. [Also in Group XIII] The spindle of each valve of a pair of butterfly valves carries a crank arm, and pins on the crank arms engage in cam slots or grooves in a single, reciprocable, actuating slide. In an embodiment, two butterfly valves are located in separate conduits 19, 19a, Fig. 3, and the spindle of each valve carries a crank arm with a pin 11 engaging in a cam slot 12. The two cam slots are provided in a single slide 13 which, when moved by an electric motor 15 through a pinion-and-rack transmission 16, actuates both valves simultaneously. The slide comprises an inverted channel member with anti-friction strips along the sides and bottom edges. The unit shown constitutes a mixing valve with the cams opposed to each other so that the valves will move in opposite directions. In a modification, for use with means to cool air for cabin conditioning on aircraft, two valves 23, 22, Fig. 4, control, respectively, the flow from a first air cooler, and the flow through a by-pass around that cooler, into a common chamber 26, and further valves 28, 27 control, respectively, the flow from chamber 26 to the second air cooler and through a by-pass around that cooler. The valves are connected in pairs to two slides 13a, 13b and, although both slides are actuated simultaneously by a single electric motor, the cams are of such contour, and are so arranged in relation to the valves, that any value of cooling can be obtained.

Title: Improvements relating to aerials
IPC: H01Q1/10
Filed: 1953-12-22
Abstract: 748,050. Aerials. ANTIFERENCE, Ltd., and BEST, N. M. Nov. 22, 1954 [Dec. 22,1953], No. 35655/53. Class 40 (7). An aerial element, for example one for use in a dipole array where it is desired to readily vary the lengths of the elements for tuning purposes, is self-supporting and made of conductive material or dielectric containing conductive material. It comprises at least two sections joined with the conductive parts overlapping but separated by insulating material so as to provide a capacitor coupling which, at the frequency of operation, has a negligible effect on the operation of the element. The sections may be tubes such as 1 and 2 forming a telescopic element. A length of the narrow tube 2 at the end contained within the tube 1 may be coated with insulating dielectric material 4 so that the required capacitor is formed. A collar 5 of insulating material inside the end of the tube 1 acts as a guide for the smaller tube and prevents it being drawn out too far. It also assists in sealing the joint and preventing the entry of water. The element may consist of a main section and a small adjustable auxiliary section. The auxiliary section may be capacitively coupled as in Fig. 2 or it may be covered all over with insulation and slide into the end of the main section; if it is made of aluminium it may be anodized to give the insulating coating. In these embodiments suitable locking means may be provided to ensure that the elements remain in a desired position when adjusted. In a modification the element consists of a main section 6 into which may be plugged one of a range of auxiliary sections 8 of different lengths. Insulation is provided at the joint so that the required capacity is obtained. The sections may be made of insulating material of suitable dielectric properties and have embedded in them conductive wires or foil; this will effectively prevent all corrosion of the conductive parts.

Title: Light sensitive copying paper and method of use thereof
IPC: G03G17/02
Filed: 1960-10-21
Abstract: 927,385. Producing photographs by light and electrolytic action. MINNESOTA MINING & MANUFACTURING CO. Oct. 21, 1960 [Oct. 23, 1959], No. 36229/60. Class 98 (2). [Also in Group XXXVI] A photo-sensitive copy sheet comprises a photo-conductive coating on an electrically conducting backing and is developed by means of an indium compound containing electrolytically reducible indium in contact with the surface of the photo-conductive coating. Passing a current through the electrolyte deposits darkcoloured metallic indium on the exposed areas. In one arrangement an electrically conductive backing such as conductive plastic or glass carries a layer of photo-conductive material such as cadmium sulphide or zinc oxide. The photo-conductive material is bonded to the base by means of a flexible film forming polymeric binder as described in Specification 864,474 and the electrolytically reducible compound acts as the developer. An aqueous electrolyte is preferred and water-soluble indium compounds such as indium iodide, nitrate, perchlorate, sulphate, sulphide, bromide and trichloride. When the electrolytically reducible indium compound is insoluble it can be superimposed on a thin top coating on the surface of the photo-conductive layer usually by means of a binder material. Such compounds are indium mono and sesquioxides, cyanide and sulphite. The thickness of the indium compound layer is usually less than 5 microns. The weight ratio of the insoluble indium compound to the binder ranges from 1: 1 to 8: 1. A light-sensitive dye in the photoconductive coating may offset the transmission loss of the top coat. In a dry developing technique a current carrying surface layer such as gelatine may be superimposed on the indium compound by a heated metal bar or roll connected as the anode and passed over the indium layer. In the arrangement shown in Fig. 2 a copysheet consisting of conductive backing plate 14 photo-conductive material 12 and indium layer 10 covered with a conductive glass plate 18 carrying a gelatine film 16 and the conductive glass 18 was connected as the anode and the aluminium backing 14 as the cathode. A 20-volt direct-current source produces a good image during a 10-second exposure to an external light source. The water-soluble indium salts may be incorporated directly into the gelatine. Specification 927,386 also is referred to.

Abstract: 760,207. Drilling-machine details; tapping. SOC. DES BREVETS WAGNER. Dec. 16, 1954 [April 27, 1954], No. 36426/54. Class 83 (3). A portable electric machine for drilling, tapping, tube-beading, &c., is connected with a device 68, Fig. 5, for stopping the machine when power consumption reaches a predetermined level, and comprises an electric-motor 3 in a housing 1, Fig. 1, provided with handle 2, the motor shaft 4, Fig. 3, being connected to a tool-carrying spindle 5 through a reversing-device. Shaft 4 drives, through gears 6, 7, a shaft 8 having fixed thereon gears 9, 10, respectively meshing with gears 11, 13, the latter meshing with gear 12. Gears 11, 12 are free on spindle 5 and spaced apart by a sleeve 16, and are connectible to the spindle by a key 18. The spindle, with its forward support 30 and the key, is slidable axially between extreme positions in which the key connects gear 11 or 12 thereto. Spring 17 urges the spindle to connect gear 12 thereto, whereby the spindle is rotated in the direction of arrow #<SP>1</SP> i.e. reverse to the working direction. When a tool on spindle 5 is pressed against the work by the operator, the spindle slides to connect gear 11 thereto for forward drive. The motor is started by closing toggle-switch 54, which connects the power-supply lines 56 to the motor through lines 60 and 58, 59, through the normally-closed contact 63 of switch 53 which is situated in a housing 43 adjacent the handle. The switch-actuating-member 51 co-operates with a cam 49 on a rod 40 coupled by arm 34 to support 30, whereby when the operator presses the machine on the work, the rod slides with the spindle and thus moves member 51 which opens contact 63 and closes contact 65. The supply to one side of the motor now passes through lines 58, 66, device 68 and line 67, so that the motor is stopped when the power consumption reaches a certain level. After stopping, and when the operator releases the pressure, the motor-switch 53 will be reversed and the motor will drive the spindle in reverse through gear 12.
