Title: Improvements in or relating to cooling-devices
IPC: H01J19/36
Filed: 1947-01-20
Abstract: 652,358. Cooling discharge apparatus. PHILIPS LAMPS, Ltd. Jan. 20, 1947, No. 1758. Convention date, Jan. 15, 1944. [Class 39 (i)] A hot body such as the anode 11, Fig. 2, of a discharge device for generating oscillations, is located in a cooling jacket 13, and water or other cooling liquid is introduced in the form of a plurality of thin jets at a speed greater than that of the mass of liquid in the jacket so as to cause turbulence, and the jets impinge obliquely on to the surface to be cooled; as a result bubbles of air or steam are removed from the surface of the hot body and deposition  of particles in the liquid on to the hot body is prevented. The liquid is introduced through apertured tubes 14 connected by perforated rings 15. The jets emerge from the holes in the rings 15 at an angle of about 45 degrees with respect to the anode surface. The Specification as open to inspection under Sect. 91 suggests that jets of liquid may be introduced through narrow tubes not con. nected by rings. This subject-matter does not appear in the Specification as accepted.

[Also in Division E2] The strut (10) (Fig. 4) of an easel type picture frame has a leg (7) integrally connected by a thinned part, forming a hinge, to a hub (11) rotatably mounted by a pivot pin (9) on the frame back (6), which is pinned in a rabbeting in the rear surface of the frame. The pivot pin is inserted in a square spigot (18) received in a hole (20) in the back (6) and the opposing surfaces of the spigot and hub have detents which interengage at quarter turns so that a long or short side of the frame can rest on a supporting surface. The pin and spigot are preferably of thermosetting plastics and project from the front face of the back after insertion in the hole. Heating and flattening against the front surface of the back welds the parts together. In modifications the pivot pin is secured by a spring tension fastener or it may be a rivet or nut and bolt.

Title: Method and apparatus for glass melting with resistance heating
IPC: C03B5/03
Filed: 1958-01-20
Abstract: 844,086. Heating glass electrically. LIBBEYOWENS-FORD GLASS CO. Jan. 20, 1958 [Jan. 31, 1957], No. 1821/58. Class 39(3). A method of treating molten glass passing through a glass melting furnace, in which said glass is heated to provide a region of upwardly rising currents of molten glass intermediate the ends of said furnace, a portion of which thermal currents sweep rearwardly towards the end of the furnace adjacent which the batch material is fed into the furnace, comprises resistance heating the molten glass in the region of the upwardly rising thermal currents over an area of limited width, said area extending on both sides of the transverse centre-line of said region. As shown, a tank furnace 10 includes a top 11, side walls 12, a floor 14 and end walls 13, and has a melting zone 16 and a refining zone 17. Raw material Z introduced at the charging end 15 is reduced to molten glass by the action of flames discharged from ports 18 which are fired so that there is maintained at substantially the location of the fourth port the centre line x-x of a hot spot X from which thermal currents flow to the rear and to the front of the furnace as indicated by the arrows in Fig. 1. To increase the temperature and velocity of the thermal currents additional heating in the area of the hot spot region is effected by passing Joule effect currents through the molten glass by means of an electrode arrangement ABC comprising opposed pairs of side wall electrode members 19 and 20 and 21 and 22 positioned ahead of the centre line x-x and constituting electrode groups A and B respectively and an electrode group C constituted by three transversely aligned substantially vertical members 23, 24 and 25 positioned rearwardly beyond the line x-x and extending upwardly through the bottom 14. The electrode groups A, B, C, are connected respectively to the terminals 27, 28 and 29 of a three phase transformer 26 so that the Joule effect currents are passed parallel to and at an angle to the centre-line x-x, the heaviest concentration of current paths being immediately adjacent the centre-line and at an angle with respect to the line. The electrodes are arranged so that the molten glass being resistance heated lies in the upper quarter of the depth of the glass.

Title: Improvements in Systems of Control for Electric Motors Operating Cranes and analogous Apparatus.
Inventor: SCOTT WILLIAM HARDING
IPC: B66C13/24
Filed: 1917-02-13
Abstract: 113,993. Scott, W. H., and Bentley, J. Feb. 13, 1917. Systems for continuous-current motors only.-A series motor operating a crane or like apparatus is provided with means for automatically weakening the field to increase the speed of the motor at any predetermined torque or current value less than the full-load value. The field weakening may be achieved by varying the connexions of the field coils between each other, or by means of a diverter resistance. In the arrangement shown in Fig. 1, the series field b of the motor B is shunted by the resistance a<3> when the contactor a is closed. The operating-coil a<2> of the contactor can only be energized in the final position of the controller E so that the motor always starts up on the full series winding. A load discriminator D has an operating-coil d connected in series with the field coil and a contact f to short-circuit the coil a<2>. This prevents the contactor a from closing the diverter circuit until the current has fallen to a predetermined amount. The switch D is designed to open when the current drops slightly from its closing value. The movement of the arm is small and the operating voltage is small, the coil being connected in series with the brake coil h. In a modificatiou, the drum controller is replaced by a series of contactors. In another moditication, a graduated diverter resistance is obtained by using a carbon block resistance connected with the resistance a<2> across the field winding in the last position of the controller. The resistance I is varied bv the action of a coil d which carries the full motor current.
