Title: Improved construction of air cooler for electrical machines
IPC: H02K9/18
Filed: 1931-12-17
Abstract: 389,928. Cooling dynamo-electric machines. ST. GEORGE'S ENGINEERS, Ltd., PURSLOW, H., ordsall Lane, Trafford Bridge, Salford, LANCASHIRE DYNAMO & MOTOR CO., Ltd. and HOWARD, J. W., Trafford Park, Stretford, both in Lancashire. Dec. 17, 1931, No. 34920. [Class 35.] An external air cooler for an enclosed machine has tubes through which external air flows and the internal air is passed over the exterior of the tubes, the cooler consisting of plates welded together. In the form shown, the tubes d, which may be of circular, oval or other section, are welded to plates D, D<1>. These plates are welded to the sheet steel plates a which are also welded together, and the internal air is passed through the chamber C by a fan on the machine shaft. Baffles may be fitted on the tubes or cooler sides, or on both, and the cooler may be mounted on the top, bottom or side of the casing, whilst the machine may have two coolers. By using strong plates and tubes a flameproof cooler may be constructed. Where two dynamoelectric machines are mounted on a common bedplate, an extended cooler with additional openings may be used or two coolers may be used beneath the bedplate.

Abstract: 191,604. Brooker, H. T. Dec. 30, 1921. Race games, mechanical.-Appliances for playing a race game comprise a series of travellers, . each traveller being advanced along a track towards a target by a series of intermittent thrusts imparted by an actuating device through the agency of a freely moving propelling unit. A number of travellers 3 are adapted to move in slots 2 arranged on an inclined board 1. A pivoted lever 4 is intermittently rocked by a projection 5<a> on a rotating wheel 6, and imparts corresponding impulses to a number of balls 5 each free to move in a slot 2, the effect of the impulses being to cause the balls to strike the travellers 3. Pivoted targets 7 situated at one end of the slots are provided with projections 8, Fig. 3, the engagement of which with a corresponding projection 9 on a traveller causes the target to assume an upright position. In order to compensate for variations in leverage, the lever 4 is lined with resilient material 4<a> of varying thickness.

Title: Humidity-sensitive sensor

Abstract: 1464605 Electric humidity sensor NIPPON SHEET GLASS CO Ltd 12 Aug 1974 [14 Aug 1973 6 Nov 1973 26 Dec 1973 7 Jan 1974 8 March 1974 25 March 1974 26 April 1974] 35489/74 Heading GIN For actuation of means for prevention of condensation on, or its removal from, a surface, a humidity-sensitive sensor 2 comprises electrodes 6, 6' on a substrate 4, suitably the said surface, the electrodes being bridged by a coating 8 of humidity sensitive material comprising hygroscopic resin 9 having electrically conducting particles 12 dispersed therein. On absorption of moisture, the material expands, the conductive particle spacing is increased and the coating resistance increases. This causes the base bias voltage of transistor TRI Fig. 11 to become lower than the emitter voltage, shutting off the collector current of transistor TR2 and de-energizing relay RL, RLC in dotted line position. Electric current is thus supplied to resistance heating elements 26 on e.g. a car rear window. Variable resistor 36 is adjusted according to the relative humidity to which the sensor is to respond. The hygroscopic resin may be an acrylate polymer, methacrylate polymer, polyvinyl alcohol, polyvinyl acetal, polyacrylamide, polyvinylpyrrolidone, polyethylene oxide, polyethylene imine, hydroxyethyl cellulose or cellulose acetate, and examples are given. The polymers are preferably cross-linked for stability of response, but not to the extent that hygroscopicity is impaired. The resistivity of the cured sensor composition is stabilized by cycling between high and low relative humidities. Since concentration of conductive particles tends to be less at the surface, a surface layer is preferably removed mechanically or chemically, and removal may be controlled to adjust the resistance to a desired value. To avoid having to cure the coating in situ, e.g. on a rear window, a preformed, cured film may be applied to the substrate using an intermediate adhesive layer of non-hygroscopic material loaded with conductive particles, the distribution of the latter being discontinuous to avoid short-circuiting the electrodes Figs. 3, 4 (not shown). The electrodes may be an interdigitated, Figs. 6, 7, 8, 9, 15 (not shown) which helps to avoid electrolytic corrosion. To this end also a water repellant coating (24) Figs. 8, 9 (not shown) may be applied to one region of the substrate and electrodes around the moisture-sensitive coating.
