Abstract: 1,229,279. Dynamo-electric machines. WESTINGHOUSE ELECTRIC CORP. 12 Dec., 1968 [18 Jan., 1968], No. 59151/68. Heading H2A. A vertically-mounted dynamo-electric machine 14, e.g. a synchronous condenser, is housed in a structure disposed in a pit 1 in the ground and comprising a fluid-tight cylindrical tank 7 and a concrete wall 4 formed in an annular gap between the side of the tank and the side of the pit. The concrete reinforces the tank walls to provide an explosion-resistant, sound-deadening housing. The tank side wall is formed from a number of (metal) wall sections 3 extending between and joined, preferably by welding, to beams 6, at least parts of which are embedded in the concrete wall 4. I-beams disposed part inside and part outside the tank may be used, as shown, or separate beams may be attached to the inside and outside of the wall sections. The lower ends of the beams are embedded in a concrete platform (12, Fig. 2, not shown) on which the tank stands. An end support for the stator 15 is disposed on the bottom of the tank, crawl space(s) being provided in it to give access to the lower rotor bearings (19). Structures 25 extending between the beams prevent rotation of the stator whilst permitting free flow of a cooling gas e.g. hydrogen under pressure, through them. Gas-to-liquid cooling devices 28 may be mounted on them. The upper end of the tank is closed by a removable cover (10). To detect gas leaks a number of perforated pipes 30, embedded in the concrete, run from underneath the tank up the side wall to ground level, where they are connected to a gas detector.

Abstract: 1,231,720. Refrigerating apparatus supplied from two sources; control of several A.C. motors. DAIKIN KOGYO CO. Ltd. 16 July, 1969 [20 July, 1968; 17 Jan., 1969, 30 Jan., 1969], No. 35873/69. Headings H2H and H2J. A portable refrigerating apparatus which can be supplied from one of two voltage sources comprises a first means for sensing which of the two sources is being supplied, a second means responsive to the first means for making the requisite connections between this source and the refrigerating unit and a third means for disabling the other source when this source is supplying the unit. A refrigerating unit comprises a compressed motor M 1  and various ancillary fan motors M 2 -M 5  together with various heating elements h 1 -h 3  for defrosting and other operations connected with the unit. A 200 volt supply is connected to terminals R 1 , S 1 , T 1  by means of a plug connector P 1  and a 400 volt supply to terminals R 2 , S 2 , T 2  by way of a plug connector P 2 , the plug connectors P 1 , P 2  having dissimilar dimensions to prevent wrong connection. The motor M 1  is a three-phase induction motor, each phase of which has two windings for series or parallel connection according to the applied voltage. The motors M 2 -M 5  are single-phase induction motors having main and auxiliary windings connectible as required by the applied voltage. A manually operable switch SS is moved to the L or H position to connect to the circuitbreaker CB whichever of the two supplies is available. If the 400 volt supply is available contacts H are closed and the breaker CB is closed. 400 volts are then applied to the transformer Tr so as to provide an output at terminals S 0 , T 0  to energize the contactors MS 1 , MS 2 , MS 3  which connect the motors M 1 - M 5  and heaters h 1 -h 3  in the manner required for 400 volt operation. If the 200 volt supply is available the switch SS is initially moved to the L position thus closing all the L contacts, the remaining part of the operation being as in the higher voltage case. The contacts L arid H have interlocking means to prevent simultaneous closure thereof. WS indicates a socalled water switch. Overload protective means OC of either a thermal or electromagnetic type are provided and are so associated with the windings of the motor M 1  as to function with either supply voltage. The means OC are operative onthe circuit breaker CB. Other embodiments show automatically controlled systems using semi-conductor elements.
