Abstract: 357,561. Galvanic batteries. BURGESS BATTERY CO., Madison, Wisconsin, U.S.A.-(Assignees of Schulte, W. B. and Zook, J. S. ; Madison, Wisconsin, U.S.A.) May 20, 1930, No. 15489. Convention date, July 30, 1929. [Class 53.] Cases.-A battery comprises dry cells 1, 2 in a metal container having insulating top and bottom closures which are held in place by the flanged edges 17 of the container and by punched-in portions of the container 12, 11. The bottom of the container may be of metal lined with insulation. The interior of the container or the exterior of the cells may be coated with insulating varnish. The Specification as open to inspection under Sect. 91 (3) (a) states that to prevent rattling of the cells in the container the strip terminals 9, 10 may be continued backwards as shown at 20, 21, Fig. 5 (Cancelled) to make contact with the under surface of the cover.

Title: Improved method of and means for mounting switch rails or blades for railways
IPC: B61L5/02
Filed: 1931-06-01
Abstract: 386,341. Railway switches. WILLIAMS, L. WYNN-, Haughton Bridge Works, Dartington. June 1, 1931, No. 15516/32. Divided on 378,571. [Class 104 (i).] In railway switches, the switch rails are resiliently mounted on inclined planes, so that they are progressively raised or tend to be raised from the slide surfaces of their chairs as they are moved away from their adjacent running rails. In Fig. 2, the gauge bar 2 is attached to the switch blade 1, and is provided with an inclined extension 7a, the bent flat portion 11 of which is borne by roller 9, preferably of the ball bearing type. The roller is carried by hanger 10 resiliently mounted through spring 15 on bracket 13 secured to the running rail 8. The weight of the gauge bar and switch blades is thus taken to any desired extent off the slide surfaces of the chairs, and increasingly so as the switch blade is moved away from the running rail. As shown in Fig. 4, a bracket 19 secured to the switch blade 1 is provided with a roller 21 preferably of the ball bearing type which bears on an inclined T-section member 22 attached to supporting beam 23. The beam is adjustably and resiliently supported from the running rail 8 by bracket 13, spring 15, and bolt 25 which passes through an elongated eye in the beam. If desired, the inclined plane may be formed directly on the beam.

Title: Improvements relating to the winding of predetermined quantities of yarn in yarn winding machines
IPC: B65H63/08
Filed: 1944-08-15
Abstract: 586,290. Winding yarn. CLARK THREAD CO. Aug. 15, 1944, No. 15556. Convention date, Dec. 17, 1943. [Class 120 (iii)] A mechanism for controlling the winding of predetermined lengths of yarn by a winding machine having detent mechanism which is disengaged to stop the winder, comprises a timer wheel geared to the winder to make one revolution during the winding of the desired length of yarn, a cam rotatable with the timer wheel and means for disengaging the detent mechanism including a member normally in the path of travel of the cam to be engaged thereby to interrupt the drive when the desired quantity of yarn has been wound. The timer wheel, consisting of two spaced discs 13 carrying a pivoted spring-urged cam 28 therebetween, is driven by reduction gearing 19, 21, 22, 23, 25, 16 from the spindle driving shaft so that the wheel makes one complete revolution whilst the package is being wound. The cam 28 thencontacts and lifts a roller 32 carried by a rod 30 attached to the arm 8 to turn the same about the pivot 9 so to release the latch piece 5 from the latch 7 to allow the usual spring-relieved clutch to be thrown out and the machine brought to rest. After passing under the roller 32, the cam 28 turns about its pivot so to be ready for another winding operation without manual re-setting. The timer wheel driving gear 16 may be replaced by another on the adjustable bracket 26 when a different number of spindle revolutions is desired before stopping the machine.

Abstract: 691,795. Cathode materials and processing. ELECTRIC & MUSICAL INDUSTRIES, Ltd. June 13, 1951 [June 22, 1950], No. 15573/50. Class 39(i). In the manufacture of a photo-electric or secondary-electron-emitting surface, layers of bismuth and silver are deposited, and the bismuth is oxidised through the silver layer solely by exposure to.oxygen. Bismuth and silver layers are condensed on to the glass envelope of a photoelectric cell into which oxygen is then admitted at room temperature; the oxygen passes through the silver layer to oxidise, wholly or partially, the bismuth to a depth of 5-10 atoms. The bismuth layer may be 30 atoms thick and the silver layer 5-10 atoms. The cell is exhausted and the semitransparent or opaque cathode sensitised by exposure to caesium. The layers may be condensed through a mesh on to a target for a television tube; alternatively a composite layer may be aggregated by heat to form a mosaic electrode.

Abstract: 712,462. Electric cooking apparatus. ENGLISH ELECTRIC CO., Ltd. June 19, 1953 [June 20, 1952], No. 15618/52. Class 39 (3) Cooking apparatus comprising an electric hot-plate assembly has a movable preferably hinged top cover 2 and a rear backplate or control assembly 5 which normally interferes with movement of said top cover, and the control assembly or backplate 5 has a plug and socket electrical connection 6 to the apparatus so that the backplate may be removed as a whole to allow movement of the top cover 2 for access from below to hot-plates 3. The control assembly 5 comprises switches, energy regulators or timing apparatus and normally overlaps part of the top cover, which is hinged at 2a to the rear of the cooker. The control assembly 5 extends the full width of the cooker and is mechanically connected thereto by additional supports, e.g. rigid struts 7 on the cooker engaging sockets formed by straps 8 on the rear of the assembly 5. The plug and socket connection 6 is behind the rear edge of the cooker and may include an earthing plug and socket. The main controls for heating circuits may be on the body of the cooker, and the splash plate 5 may carry a timer, which may be connected to any of a number of heating circuits.

The cage is joined by its periphery to the pipe wall at its downstream end so that fluid flow must be inwards through the cage wall 5 and then out through the cage end 4. The downstream end of the side wall 5 is surrounded by a helical washing channel 9, formed partially by the gap between the cage wall 5 and the pipe and partially by an outward extension of the pipe at this point, and having inlets 6 for washing fluid upstream of an outlet 7 for removal of solids which have collected on the outside surface of the cage wall. An adjustable throttle element 12 which may completely close the flow passage is mounted upstream of the cage. An adjustable flow restricting element 13 in the form of an inflatable ring is mounted between the pipe wall and filter cage upstream of the washing channel. This flow restricting element may alternatively be mounted downstream of the. washing channel (Figs. 3 and 6 not shown) in which case it is mounted between the pipe wall and an annular supporting element (14) which internally supports the filter cage. The closed end of the cage may be formed as a pressurerelease by-pass valve (18, Fig. 6, not shown). A further throttle element (16) adjustable both longitudinally along and rotably about the axis of current flow through the pipe may be mounted in the region of the washing channel (Figs. 4 and 5 not shown).

A jib crane for the loading and unloading of containers 2 of uniform size has a pivoted jib 15, is rotatable about a vertical axis and has a loading member 1 suspended by two pairs of cables 13, 14 which cross each other between the loading member 1 and the top of the jib 15, wherein the pairs of cables 13, 14 run out from a cable drum 16 over pulleys 17, 18, respectively, arranged on a tower 19 of the crane and then over pulleys 20, 21, respectively, arranged at or near the top of the jib 15, the pulleys 17, 20 being spaced from the pulleys 18, 21 so that the cables 13, 14 run substantially parallel to each other between the tower 19 and the top of the jib 15, the pulleys 17, 18 and the jib pivot 22 lying on one substantially straight line and the pulleys 20, 21 and the jib pivot 22 lying on another substantially straight line. The arrangement is such that the loading member 1 and the container 2 remain substantially in a horizontal position when the jib 15 is luffed. The inclination of the loading member 1 and the container 2 can additionally be limited by providing a separate drum for each pair of cables 13, 14, each drum being rotated by a differential mechanism and a motor being connected to one of the drums so that the container 2 retains its horizontal, or other pre-set inclined, attitude controlled by a mercury balance switch or free pendulum (not shown).
