Abstract: 255,618. Avery, Ltd., W. & T., and Sykes, C. M. July 2, 1925. Compound-lever apparatus.-In a weighing-apparatus the pull due to the load is transmitted through an intermediate lever to a pair of superposed levers provided with pendulous resistants the axes whereof are disposed in planes containing the fulcra of the levers, the pair of superposed levers being linked together and connected to the weight indicating mechanism, the intermediate lever being adapted for alternative connection to one or other of the superposed levers whereby the leverage or power of the mchanism can be varied to suit light or heavy loads. The draw rod 3 leading from the bottomwork of the scale is connected through the intermediate lever 5 to a lever 11 coupled by a link 14 to lever 15. The fulcrum support 8 of the intermediate lever is adjustable on the housing so that the leverage of the lever may be altered. The levers 11, 15 carry pendulum resistants 20, 21 the axes of which are disposed in planes passing through the fulcrums 12, 16. The connecting link 14 is coupled by a rod 23 to the rack and pinion of the usual indicating pointer 28. In order to alter the leverage of the mechanism and thus make the scale available for weighing both light and heavy loads, the levers 5, 15 are provided with means whereby the two levers may be coupled directly together instead of connecting the levers 5, 11. Locking-mechanism.-A cam 36 rotated by an external knob may be brought into engagement with a cranked arm 35 extending from the lever 15, thus locking the system against movement. A counterweight 40 automatically returns the locking cam to inoperative position if a full locking movement of the cam has not been made. Vibration, preventing.-A dashpot 32 is connected to the lever 11 by a rod 31.

Title: A carriage for assisting in the take-off of aircraft
IPC: B64F1/10
Filed: 1948-06-26
Abstract: 647,318. Launching aircraft. GERIN, J. J. M. J. June 26, 1948, No. 17230. Convention date, June 26, 1947. [Class 4] An aircraft launching-device which comprises a self-propelled carriage, a cradle adapted to support an aircraft and rotatably mounted on the carriage to orientate the aircraft in the direction of the wind, securing means for holding an aircraft to the cradle and means for releasing the securing means, is characterized by the fact that retaining means are provided for maintaining the cradle stationary with respect to the carriage which comprises its own steering means as well as means for releasing the retaining means after a certain speed has been attained and for enabling the aircraft to be automatically orientated in the direction of the wind. In the embodiment shown a low chassis mounts a cradle 10 for attachment to an aircraft fuselage 11. The carriage is driven by either piston or jet engines or a combination of both. Fig. 1 shows front and rear steering wheels 4 and 5 respectively, twin driving wheels 6 and supporting wheels 6a. To launch an aircraft the carriage is driven beneath it and the cradle 10 is raised from resilient abutments 15 by a screw device 14a acting on the ball-joint 14 until locking devices 17 engage the aircraft fuselage. Struts 18 are then erected to support the cradle corners, the aircraft undercarriage is retracted and the assembly moves along the runway. At  a  suitable speed the struts 18 are swung down and the aircraft oriented into the rotative wind. When the take-off speed is reached the locking devices 17 are disengaged and the aircraft is released. The cradle is prevented from tilting and fouling the aircraft by a double fin 13 mounted on a beam 12. Wings 1 on the carriage provide a downward thrust to compensate for the lift of the aircraft before it is released and flaps 2a in vertical fins 2 are used to brake the carriage after it is released. Further rapid braking may be obtained by means of a parachute. Rudders 3 assist the fins 2 in stabilizing the carriage during launching. The weight of the carriage may be increased by ballast, e.g. water tanks, to increase wheel adhesion.

Title: Improvements in or relating to automatic signalling systems
IPC: H03K17/62
Filed: 1957-05-31
Abstract: 851,445. Electric selective signalling. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 31, 1957 [June 5, 1956], No. 17374/57. Class 40 (1). [Also in Group XXXIX] Means for establishing a signal connection between one of a number of inlets and one of a number of-outlets comprises a matrix of transis-  tor amplifiers, the emitters being connected to the conductors A1-A3 of the inlets and the collectors to the conductors B1-B3 of the outlets, the inlets and outlets being connected to resistance ground and resistance battery, respectively. The base circuits are each connected by a resistor such as R11, Fig. 1, or D11, Fig. 2, to a voltage supply. When the voltage of one of the inlets, say A2, is raised and that of one of the outlets, say B1, is lowered then the related transistor T21 conducts. The bases of transistors associated with one outlet, say B1 are associated with a circuit comprising rectifiers G1, G2, resistors W1, R4, R5 and capacitor C1 such that G1 conducts in both the rest condition and if one of the associated transistors is conducting. G2 is normally conducting but is cut off when one of the associated transistors conducts. At release, G1 is temporarily cut off. The circuit reduces cross-talk.

Title: Process for the manufacture of vulcanised coatings
IPC: C08L81/00
Filed: 1937-06-24
Abstract: Vulcanized coatings or impregnations are produced by incorporating zinc oxide in an aqueous suspension obtained by causing a water-soluble inorganic polysulphide to react with an organic polyhalogenated compound in the presence of finely divided barium sulphate, coating or impregnating materials of any kind with the suspension, and then subjecting the impregnated or coated material to a high temperature suitable for vulcanization, e.g. 100 to 160 DEG C.  Polyhalogenated compounds specified are ethylenedichloride, 1.3-dichloropropane, p-xylylene dichloride, b -b 1-dichlorodiethylether, b -b 1-dichlorodiethyl sulphide, di-(ethylenechlorhydrin)-formaldehyde acetal and the products of the condensation of aldehydes and chlorine-containing alcohols.  Prior to the incorporation of the zinc oxide, the plastics may be subjected to the action of sulphur-stripping p  substances such as sodium hydroxide or sodium sulphide. Vulcanization accelerators, e.g. substituted dithiocarbamic acids, anti-ageing agents such as N-phenyl-b -naphthylamine or the condensation products of aldol and naphthylamines, filling agents, e.g. carbon black, chalk and talcum, and wetting or dispersing agents, e.g. condensation products of formaldehyde and naphthalene sulphonic acids, may be incorporated in the suspension.  When a filling agent is used, a dissolving or swelling agent for the sulphur-containing plastic such as benzene, ethylene dichloride, or 1.1.2-trichloroethane may be added to the suspension before or after the addition of the zinc oxide or in admixture therewith.  The material to be coated or impregnated, e.g. textiles, wood or metals, may be pretreated with a wetting agent.  In examples (1) to (5), an aqueous suspension of a plastic obtained by reacting sodium tetrasulphide and di-(ethylenechlorhydrin)-formaldehyde acetal in the presence of barium sulphate is mixed with zinc oxide, a dispersing agent consisting of an aqueous suspension of the sodium salt of the condensation product of b -naphthalene sulphonic acid with formaldehyde and (1) tetramethylthiuram disulphide, (2) dibenzothiazyl disulphide, (3) dibenzothiazyl disulphide and mercaptobenzimidazole, (4) tetramethylthiuram disulphide, carbon black and 1.1.2-trichlorethane, or (5) tetramethylthiuram disulphide, carbon black, ethylene chloride and water.  In example (6), an aqueous suspension of a condensation product of b -b 1-dichlorodiethylether and sodium tetrasulphide prepared in the presence of barium sulphate is mixed with zinc oxide, dibenzothiazyl disulphide and the above-mentioned dispersing agent.  The suspensions thus obtained, which may be diluted with water, are applied to the materials to be coated or impregnated and vulcanized by heating.
