Title: Improvements relating to armature windings for dynamo electric machines
IPC: H02K3/12
Filed: 1932-01-19
Abstract: 395,714. Coils and windings for dynamo-electric machines. PRITT, S. E., 36, Abbeydale Park Rise, Totley Rise, Sheffield, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Jan. 19, 1932, No. 1660. [Class 35.] A two-turn coil for the armature of a dynamoelectric machine having stepped or tapered slots is obtained by cutting from a bar or strip 1, tapered or stepped in cross-section, two U- shaped blanks 2, 3 as shown in Fig. 1 ; one of the blanks is turned end for end, and the free ends of the inner bars 4, 5 are joined together by a cleft 8 forming a coil as shown in Fig. 3. The bars 6, 4 occupy the outermost and the next to the outermost positions in a slot and the bars 7, 5 the innermost and the next to the innermost positions in another slot. The free ends of the conductors 6, 7 are secured to commutator risers and may be pressed or shaped to a suitable size. The cuts in the conductor strip may be formed by punching, shearing or stamping, and the cross-sections of the resulting straight portions are preferably equal. A number of coils may be located side-by-side in the slots, all the coils occupying the upper half of one slot and the lower half of another being insulated by a common sheath before insertion in the slots. In order to improve commutation, the two turns comprising a coil may occupy different positions in the circumferential direction as shown in Fig. 7. Specification 349,975 is referred to.

Abstract: 394,898. Road-traffic signals. ELEKTRIZIT€TS AKT.-GES. W‰DENSWIL, 125, Uethbergstrasse, Zurich, Switzerland. Jan. 18, 1933, No. 1680. Convention date, Jan. 18, 1932. [Class 118 (ii).] A signalling device sensitive to the direction of travel of a vehicle comprises a rubber or like sleeper strip 1 yielding on the passage of a vehicle to effect in turn in each of two air chambers 3, 4, a brief increase above and fall below normal pressure and thereby to move diaphragm contacts 13, 14 so arranged that a circuit to a signal 15 is completed only if the phase of increased pressure in chamber 4 overlaps, in time, the phase of reduced pressure in chamber 3. It will be seen, therefore, that to actuate the signal 15 the chamber 3 must be passed over first. The duration of the pulses is determined by the adjustment of the openings 5, 6.
Patent GB-784218-A (GB)
Title: Measurement of the proportion of constituents in mixtures
IPC: G01N25/18
Filed: 1954-01-20
Abstract: The proportions of constituents in a flowing medium are mechanically indicated by transferring heat to or from the medium and flowing the medium at a constant rate through a measuring pipe, the change in length of which, relative to a comparison pipe, is used to give the mechanical indication.  The comparison pipe may be held at a known temperature or it may be heated or cooled similarly to the measuring pipe while a medium of known <PICT:0784218/III/1> <PICT:0784218/III/2> composition flows through it.  The apparatus of Fig. 4 is used for determining the wetness of steam; the steam to be tested flows from tangential inlet 17 through measuring tube 12 where it is heated by superheated steam in tube 13, and unheated steam flows through comparison tubes 11; the tubes are all connected to junction piece 14 and the wetness is indicated on scale 16.  Other apparatus is described in which the steam is heated electrically or by mixing the sample with hot steam.  The carbon monoxide and carbon dioxide contents and the temperature of flue gas are determined with the apparatus of Fig. 7.  Flue gas sampled at 27 flows through pipe 29, past heating coil 31, where the carbon monoxide is converted to carbon dioxide, to pipe 32 and thence to pipe 37; air entering at 42 flows through pipes 30, 38.  The temperature and pressure of the gases entering pipes 37, 38 are equalized by heat exchanger 34 and fans 36, and the pipes are heated by electric heaters 39.  The carbon monoxide content is measured by the change in length of pipe 32 relative to pipe 29 and indicated by lever 44, carbon dioxide content by the change in length of pipe 37 relative to pipe 38 and indicated by lever 45, and temperature by the change in length of pipe 29 relative to pipe 30 and indicated by lever 46.  A combined measurement is given by the point of intersection of link 50 with scale 47.  The humidity of air may be measured by cooling an air stream to separate the moisture as droplets or a cloud and then passing the stream through an electrically heated measuring pipe and in parallel through an unheated comparison pipe.  Reference is also made to the measurement of dust or ash in air or flue gases.

Title: Conductor bar end fittings for direct-cooled dynamo-electric machines
IPC: H02K3/24
Filed: 1954-01-21
Abstract: 786,725. Cooling dynamo-electric machines. GENERAL ELECTRIC CO. Jan. 21, 1954 [Jan. 27, 1953], No. 1883/54. Class 35. In a machine with hollow stator conductors or other axial cooling ducts within the main insulation, conductor-bar end-fittings are provided to serve as electrical end-connections and as ducts for the gas or liquid coolant. As shown in Figs. 4 and 5, the end fittings 31c, 32e are of copper or other conducting metal, and have a pair of sockets 49, 50 into which the conductors 4a, 4b are soldered. The conductors are built up of hollow strands 51, 52 through which the coolant passes. The fitting may be fabricated of separate parts suitably interconnected or made as a solid unit. Various modifications are described including the use of two radially displaced stacks per slot with the fluid in the two stacks passing in the same or opposite directions, and in the same or opposite directions to that in the conductors in the adjacent slots. Instead of using hollow conductors, solid conductors with separate tubular ducts may be included within the main insulation, and various arrangements of these with respect to the conductors are described. For liquid coolant the end-fittings are connected by insulating tubes, but where gaseous coolant is used, shoots 93a as shown in Fig. 37 may be used. This Figure also shows an arrangement in which coolant is passed through the also in two directions, as well as making the end connections 47a, 47b.
Patent GB-509778-A (GB)
Title: Improvements in the manufacture of ketene, acetic anhydride and homologues thereof
IPC: C07C45/89
Filed: 1938-01-20
Abstract: 509,778. Ketenes ; acid anhydrides. FALLOWS, L., and MELLERS, E. V. Jan. 20, 1938, No. 1925. [Class 2 (iii)] Ketene, acetic anhydride and their homologues are produced by the thermal decomposition of the corresponding aliphatic acid vapour at 500 = 1000‹C. in the presence of phosphoric acid and of zinc or cadmium oxide, with or without the presence of ammonia or a volatile organic nitrogen base. The zinc oxide may be used as such or as a compound yielding zinc oxide under the reaction conditions, and may be supported upon a carrier or may be dispersed throughout the reaction space. The zinc compound and the phosphoric acid (and nitrogen base if any) may be added in solution or suspension to the acid vapour; or zinc oxide may be added to the acid to be treated before it is vaporized. The acid vapour may. be preheated to within 20-100‹C. of the reaction temperature or, up to the reaction temperature. The anhydride and ketene may be separated by condensing the reaction vapours to liquefy the water, acid, and anhydride, or factionally to liquefy the anhydride ; in such a process it is advantageous to effect the condensation in the presence of liquids such as benzene, toluene, xylene and chlorbenzene which form azeotropic mixtures with water. The invention is described with reference to the treatment of acetic acid, but propionic, butyric and other acids may be used. In examples (1) zinc nitrate solution is evaporated in the presence of pumice granules which are then heated to produce zinc oxide ; acetic acid vapour is preheated to 620-630‹C. and an acetic acid solution containing triethyl .phosphate and pyridine is injected into the vapour which is passed over the solid catalyst at 690‹C. ; (2) acetic acid vapour is preheated to 640‹C. and the same acetic acid solution to which zinc acetate has been added, is injected ; the mixture is passed through an empty reaction tube at 700‹C. and the anhydride is condensed .fractionally in the presence of benzene. Specification 256,664, [Class 2 (iii)], and, in the Provisional Specification, 280,972 and 317,907, [both in Class 2 (iii)], are referred to.

Abstract: 392,666. Discharge lamps . SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Jan. 25, 1932, No. 2276. Convention date, Jan. 24, 1931. [Class 39 (i).] An equipment for light therapy consists of electrical accessories and a reflector together with a number of metal vapour lamps having different fillings, which are so constructed that any one of the set of lamps may be employed with the reflector to produce its own radiation. The reflector or lamps or both are so made that the lamps are interchangeably attachable to the current-carrying parts of the apparatus. In one construction, Fig. 1, a trough-shaped reflector 1 carries holders 2, 21 on which members 3, 3<1> carrying contacts 5, 51 are adjustably mounted so that lamps of different lengths, chosen so that the temperature of the lamp is sufficient to vaporize the filling, may be mounted thereon. The electrode chambers may be surrounded with heat insulating material. In a modification, a U-shaped lamp has a metal oross piece clamping the two legs and adjustably mounted on one limb of an angle bracket secured to the bottom of a bowl-shaped reflector. For a difficultly vaporizable filling, the legs of the lamp may be surrounded with heat-insulating material or with coils carrying current in parallel with the discharge. The limbs may be brought close together so that the insulation surrounds both electrode chambers. The thermal operating conditions may be modified by the arrangement shown in Fig. 3, wherein a reflector 12 is furnished with apertures which may be closed by flaps 13. A coverplate 15 of heat-insulating material may be used when great heat is required. In Fig. 7 a means for interchanging two lamps is shown. A part of the reflector 26 is cut away and a body pivoted at 27<1> and having reflecting parts 28, 281 conforming to the parabolic shape of the reflector 26 carries the lamps 29, 291 which may be interchanged by rotating the body through 180‹. The ultra-violet radiating characteristics of mercury and cadmium lamps as employed according to the invention are discussed in the Specification.
