IPC: H02P1/28
Filed: 1927-12-02
Abstract: 303,259. Smith, F. Dec. 2, 1927. Alternating-current motors.-A squirrel cage induction motor of three or more phases is started by energizing two or more, but not all, of its phases and subsequently energizing the remaining phase or phases. Additional steps may be obtained by decreasing a resistance in one or more of the phases. The application to a 3-phase motor without resistance steps is shown in Fig. 1 in which power is brought to the terminals 17 of a starter connected, as shown, to the stator coils 10, 11, 12. In the first bridging position 1 of the switch contacts the coils 10, 11 are energized and in the bridging position 2 the third coil 12 is also energized. In the form shown in Fig. 2, a resistance 20 is included in the switch line from the junction of coils 10, 11. In the bridging position 1 of the switch, coils 10 and 11 are energized through the resistance; in position 2 the winding 12 is energibed in addition; and in position 3 the resistance is cut out, giving full motor speed.

Title: Improvements connected with drying apparatus for ceramics and such like
IPC: F26B15/24
Filed: 1931-11-25
Abstract: 372,700. Drying-apparatus. HAAS, H., 4, Hackenbergerstrasse, Lennep, Rhineland, Germany. Nov. 25, 1931, No. 32646. Convention date, Dec. 19, 1930. [Class 34 (ii).] Drying-apparatus for use in the ceramic and similar industries comprises a chain device carrying a number of swing-like supports on which the clay, porcelain, gypsum, or similar articles are placed, and a chamber which is divided into a compartment where the articles are treated with heated moist air and a compartment where the partly dried materials are treated with heated dry air. Between the two compartments there is situated a series of fans, preferably on a common shaft, which effect the required air circulation. Some of the fans circulate air through the first compartment, some circulate air through the second compartment, and others remove waste air from both compartments. As shown, a chain device K carries the swings S through the drying chamber A. The wet objects are placed on the swings at E and taken off dried at B. The swings are cooled during the travel of the chain device from the wheels R6 to the wheels R5. The series of fans L are built in or introduced at the top of the chamber A. Fans L1 send air downwards into the heating shaft H provided with steam pipes, and this air enters the right-hand compartment and is drawn up by the suction side of the fans. The air in this compartment becomes moist by evaporation from the moist articles, but the humidity may be increased by introduction of steam or water spray from the nozzle Z. In the left-hand compartment, air is passed by fans L2, L3 from the top and is drawn back from below through the heating shaft H. Fans L4, -L5 draw air from both compartments and carry it outside through the uptake shaft M.

Title: Improvements in and relating to apparatus for the deposition of viscous liquid materials
Inventor: BEALE EVELYN STEWART LANSDOWNE
IPC: B41F1/40
Filed: 1956-10-29
Abstract: <PICT:0821152/III/1> <PICT:0821152/III/2> In apparatus for depositing thin layers of paint, ink and other viscous materials in accurately-defined patches on surfaces, of the kind comprising a matrix having one or more shallow cavities in its operative face, conduits leading through the matrix for the introduction of coating-material to the cavities which are closed by the surface to be coated, and means for controlling relative movement between the matrix and the said surface, the separation of the matric and the surface, after coating, takes place in three phases, the first being of small predetermined extent at high speed, the second at low or nil speed, and the third at a speed higher than that of the second phase and of greater extent than the first.  The second phase allows time for the breakage of most or all of the small strings of coating-material formed between the matrix and the coated surface. As shown, the matrix 5 is fixed to a frame structure comprising base 2, posts 3, and an open top frame 4, the matric having on its under side a number of shallow cavities 6 bounded by ridges 7 and connected, by tubes 9, to pumps 12 which supply coating-material from reservoirs 14. Beneath the matrix 5 is a platen 18 carried by the ram 17 of a vertical hydraulic press 15.  The direction of movement of the ram is determined by the admission of hydraulic fluid, supplied through a conduit 29, to the spaces above or below the piston 28, under the control of a double-acting valve comprising a body 20 and a spool 21 carrying lands 22,23, small movements of which mask or unmask the ports 24,25 of the press.  The valve spool 21 is operated by being pivotally connected at 39 to a lever 35, one end of which is pivoted to a collar 38 on the ram 17 and the other end carrying a cam follower 34 which is held up to a cam 33 by a spring 54.  The cam 33 is mounted on a shaft 32 driven at constant speed by an electric motor, and is suitably profiled to give the required rates of opening of the ram.  Also carried by the shaft 32 is a cam 40 which operates the plungers of the pumps 12 through a rod 42, and a lever 45 which acts on a plate 47, mounted for vertical movement on pins 48.  Sheets or cards to be coated are fed singly and in succession from a lay board 50 by feeder bands 51, which are driven at intervals from the shaft 32 or a part driven in synchronism therewith, brought to rest over the platen 18, coated by closure of the press and operation of the pumps 12, and removed, after opening of the press in three phases as described.  They are then received by bands 52 and usually introduced into a drying oven 53.

Abstract: 751,468. Electrically heated windscreens. LIBBEY-OWENS-FORD GLASS CO. Nov. 22, 1954 [Dec. 1, 1953], No. 33664/54. Class 39(3). A windscreen for a motor car comprises a glass sheet with a substantially flat central part e substantially covered by a transparent coating 20 forming . an electric heating resistance terminating inwards of the end parts g of the windscreen, which are bent back, current being led to the coating by electrodes 21 along opposite margins of the coating: Two strips 21 of electrode material e.g. a silver flux are applied to a flat glass sheet inwards of two opposed edges, and the sheet is moved on a monorail into a furnace where it is heated almost to fusing point e.g. 1250‹F. to bake on the electrodes, and a solution of tin chloride is sprayed on to the hot glass to form a uniform coating of tin oxide. After cooling, the coated sheet is preferably matched with a second uncoated flat glass sheet to form a laminated sheet and carried on a mould into a furnace where the glass sheets are supported at opposite edges and sag into the mould to a shape shown in Fig. 5 and allowed, to cool slowly to anneal the glass. After cutting the glass to shape so that the electrodes are at the edges, the coating is removed at the bent ends e.g. by rinsing with chemicals. Where the electrodes converge towards a tapered end of a windscreen at j, Fig. 10, the coating is given a concave edge 44 to ensure even heating of the coating. Alternatively the whole windscreen may remain coated, except for a narrow passage across the screen at the ends of the electrodes, so that no current can pass into the coated end portions. The electrodes terminate inwardly of the bent ends of the windscreens, but when the coating is wholly removed at these ends, the electrodes may extend to the extremities of the windscreen at the same or opposite ends for connection to the current supply. A thin strip of coating may be removed centrally across the glass to divide it into two portions and the corresponding central parts of the electrodes are also removed, so that each portion may be independently supplied with current e.g. through rheostats. Two glass sheets, one coated, may be laminated with a bonding layer of thermoplastic, and the uncoated sheet is either slightly narrower than the coated sheet to allow a current lead to be soldered to the exposed electrodes, or the uncoated sheet is notched at its inner edge to allow attachment of leads in parallel to an electrode. The windscreen is mounted in a continuous groove '52 in a rubber or like channel 53, through which the current leads 61 pass and may be soldered to a flat metal plate 59, which is pressed by a bowed leaf spring 60 located in the bottom of the groove 52. In this case the electrode is extended at 58 to the outer edge of the coated sheet by applying a similar material to the edge of the glass continuously or at spaced points.
