Abstract: 411,221. R÷ntgen ray tubes. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Klinckmann, A. ; 184, Craig Place, Lombard, Illinois, U.S.A.) Feb. 1, 1933, No. 3124. Convention date, Feb. 1, 1932. [Class 39 (i).] A method of joining glass walls having different co-efficients of expansion consists in fusing the glasses to a metal member that conforms to the shape of the walls. The method is intended particularly for forming a joint between tubes of soft glass and of hard borosilicate glass in the evacuation system of an X-ray tube. For this purpose, the soft glass tube 13<a> is welded by the usual means to the edge of a thimble 10 of copper-plated nickel steel. The end of a hard glass tube 17<a> is also welded, by the method described in Specification 392,421, to the edge of a second thimble 14 of nickel steel. The two thimbles, which have openings 11 in their ends, are secured to one another by means of silver solder, copper brazing, or by other suitable means to form a vacuum-tight joint. In a modification, the two tubes are joined by a single tubular sleeve of nickel steel.

Abstract: 764,280. Space-heating equipment. BENTELER-WERKE AKT.-GES. WERK NEUHAUS. Feb. 2, 1955 (Feb. 9, 1954; May 7, 1954], No. 3132/55. Class 64(2) A heating element for space-heating equipment comprises thin-walled flow conduits of small diameter through which a vaporous heat carrier circulates, the conduits being in laterally spaced parallel relationship and being connected over at least part of their length by a thermally conductive bridge, the conduits and bridge being integrally formed. The element may be formed as shown in Fig. 2, in which a strip of iron or steel is bent and welded so as to form a longitudinally slotted pipe and is then compressed to form two conduits 9' interconnected by a bridge portion 8. Alternatively, the element may be formed as shown in Fig. 7 in which the longitudinal edges 17 of the strip are bent and welded to the middle portion of the strip to form the flow conduits, the corrugations 18 being provided to stiffen the construction. The remaining Figures illustrate various ways in which the flow conduits 9 of the heating elements may be included in a space-heating system (or "radiator"). The elements are bent into U-shape and the conduits may be connected to a single distribution pipe 13 as shown in either Fig. 5 or Fig. 11. In other arrangements, the heating elements are connected between a pair of distribution pipes (as shown in Figs. 10 and 12) which are in turn connected to the flow and return pipes of the heater system. In the modification shown in Fig. 6, the heating element is bent into a zig-zag shape and is adapted to be connected to the flow and return pipes of the system via two distribution pipes. As shown in Fig. 14, two heating elements 7a and 7b may be connected together by forming the bridge portions 8 of the elements with depressions 22 and welding the corresponding depressions of the two elements together.

Abstract: 819,795. Submarines' escape dinghies. R.F.D. CO. Ltd., JONES, W. G. A., and BOWMER, K. C. April 22, 1958 [Jan. 29, 1957], No. 3136/57. Classes 113 and 115. [Also in Group XXI] Life saving apparatus for submarine craft comprises an inflatable dinghy 11 in a buoyant container 10, a free flooding cylindrical housing 12 built into the superstructure 13 on the pressure hull 14 of the craft, a cover 15 for retaining the container in the housing means controlled from inside the pressure hull for releasing said retaining cover to permit the container to float to the surface when the craft is submerged, means for inflating the dinghy and means for releasing it from the container. A dinghy mooring line 26 is stowed in the space around a hollow cone 25 in the housing, is anchored on the hull at 28 and may contain a telephone cable which is led into the hull at 29. To release the apparatus compressed air from a reservoir 81 is introduced into a cylinder 87 to raise a ram 75. This lifts the container 10 to force open the cover 15. As the container floats upwards a cap 76 moves out of contact with the ram 75 so that a spring 74 rotates linkage 69-64-66 about pivot 65 thereby moving a block 67 clear of collars 58, 68 on a rod 55 connected to a piston 61 in a cylinder 57 open to the sea through a passage 62. When the container approaches the surface, the reduced pressure acting on the piston 61 enables a spring 59 to move the rod 55 to the right, thus rotating a lever 51 to actuate the operating head 46 of a gas cylinder 45 to release gas into the dinghy. The inflated dinghy forces apart the two hemispheres 10a, 10b of the container, from which it releases itself. It is attached by a painter 63 to the hemisphere 10b which is secured to the mooring line 26 and acts as a marker buoy (see Group XXI).

Title: Improvements in or relating to the conversion of polyphase current to unidirectionalcurrent impulses
IPC: H02M7/40
Filed: 1948-02-09
Abstract: 654,583. Phase changing; converting; switching systems for welding arcs. SCIAKY, D. Feb. 9, 1948, No. 3731. Convention date, Sept. 1, 1944. [Classes 38 (ii) and 38 (iv)] [Also in Group XL (c)] A method of converting polyphase current to unidirectional current pulses consists in rectifying the current in each phase respectively of the polyphase source to derive current pulses having the same polarity, passing the rectified currents through separate primary windings of a transformer to cause magnetizing current pulses to flow in these windings to produce a unidirectional rise in the flux so as to produce a unidirectional E.M.F. in the secondary winding of the transformer. A transformer 10 has three primary windings 14, 15, 16 each fed from a separate phase of a three-phase A.C. supply through a relay contact and a unidirectional conducting device. A sequencing timer 28 operates, on closure of a switch 29, to energize the relay to close the contacts thereon so that each winding is fed from the corresponding phase with unidirectional current to cause a steady rise of flux in the transformer core. After a pre-determined time interval T1-T2 the timer 28 operates to de-energize the relay and so remove the current supply to the windings. One pulse of unidirectional current is thus induced in the secondary winding 11. After another time interval T2-T3 the operation is repeated and thus a series of unidirectional pulses is induced in the winding 11. If another unidirectional device is connected in back-to-back relation with each of the existing devices and another relay is operated by the timer alternately with the existing one the pulses in the winding 11 will be alternately of opposite polarity producing a form of alternating current.,
