Abstract: 297,400. Jackson, L. Mellersh-, (Burgess Laboratories, Inc., C. F.). June 13, 1927. Electrodes; connections.-The anode of a dry cell is made in the form of a shallow perforated pan, the interior of which forms an expansion chamber for the electrolyte which is situated on the other side of the pan. Fig. 7 shows one form of anode consisting of a zinc pan 1 having perforations 2 and a larger opening 3 in the centre. Two of the edges 5 are serrated and projections 4 are provided to support a separator and the cathode which rest of the anode. Fig. 4 shows a portion of the cathode which consists of a metal plate 18 supporting a mixture 22 of a carbonaceous material and a binder such as graphite, carbon and paraffin. Above this mix- ,ture is placed the depolarizer consisting of graphite and manganese dioxide. Fig. 1 shows a complete battery consisting of three cells each comprising a cathode and depolarizer 18, 22, 26 surrounded by an insuating collar 24 which supports the pan-shaped zinc anode 1. The electrolyte is introduced into each cell through the opening 3 in the anode. Above the zinc pan 1 is a paper sheet 26 and the cathode of the adjacent cell. The plate 18 of each cathode projects at each end and is turned down and forced over the serrated edges of the adjacent zinc pan and the joint completed by soldering. Instead of the panshaped anode being made completely of zinc it may consist of a zinc sheet with an insulating frame. The cathode may also take several forms. In one modification the plate 18 is replaced by wire gauze. In another modification a carbon plate is used instead of the metal plate 18, the edges of the carbon plate being plated with metal. Connection is made to the adjacent anode by a soldered metal strip. The carbonaceous mixture 22 may be replaced by a layer of carbon particles attached to the plate 18 by adhesive. The complete battery may be inserted in a pasteboard casing which is filled and sealed with pitch &c. Specification 128,332 is referred to.

Title: An improved method of and means for the removal and transport of ash and the like furnace residues
IPC: F23J1/00
Filed: 1946-05-27
Abstract: 614,250. Ash removal from a furnace. DANIELS, A. W., and B. V. C. INDUSTRIAL CONSTRUCTIONS, Ltd. May 27, 1946, No. 16047. [Class 78 (i)] [Also in Group XII] An ash hopper 1, Fig. 2, which is formed with sides 2, 3, 4, converging to a longitudinally inclined base 11 having gate 14 at its lower front exit 13, has a series of upwardly and downwardly - directed water jet assemblies 18 for washing away the ash. Fig. 2. Gate 14 is swung open by means of handle 16 and the jet assembly 181 plays water through the entrance. When sufficient ash has flowed away to uncover twin jet assembly 18<11> these two jets squirt water up the slope into the ash mass. Next, jet assembly 18<111> is uncovered as the ash retreats and is brought into operation to squirt water down the slope. Next, jet assembly 18<@1V> is uncovered and in turn squirts water up the slope into the mass. The efflux passes out into sluiceway 19 where it meets a further jet 18<1>. The brick wall lining 6 of hopper 1 is metal-faced at 9. The base 11 supports interlocking hollow metal blocks 10 through which runs cooling water from jet 64. Fig. 4. Jet assembly 21 pivots about hollow spindle 22 through which water is fed to nozzle 24. When water is admitted under pressure, the reaction of the water forces the jet assembly 21 into the position of Fig. 4 against stop 26 so that jet 24 may squirt water over hopper floor 10 and, when water is cut off, the jet assembly swings round under the .weight of counterweight 31 until the second stop 26<1> comes against the metal floor and presents the flat surface 21a into the flooring, so avoiding any impedance to the water flowing over the blocks 10. Fig. 8. A water jet may also be introduced up or down the slope through the brick lining 6 of the wall by means of nozzle 39, the housing 34 of which is secured to inlet pipe 36 which slides within supply pipe 37. Inrush of water automatically slides the inlet pipe and housing forward so that the jet jumps up to spray water inside the hopper and, when the water is cut off, the housing recedes into the wall under the action of spring 61 expanding against collar 50 fixed on the inlet pipe. Alternatively, handle 62 may effect the displacement of the jet. Fig. 13. Similar to Fig. 8. The displacement of jet housing 34 due to pressure of water works against counterweight 53 which restores the housing beneath floor 10 when the water is cut off. The jets may all be controlled electrically or hydraulically from a single panel and come into play automatically as required.

Title: Improvements in magnetic snap action electric switches
Inventor: FLIGHT THEODORE NICHOLAS
IPC: H01H37/66
Filed: 1955-06-09
Abstract: 803,346. Thermal switches; magnetic switches. RHEOSTATIC CO., Ltd. May 4, 1956 [June 9, 1955], No. 16613/55. Class 38 (5). A magnetic snap-action switch suitable for operation by temperature or pressure-sensitive elements, comprises a channel-iron member 15 pivoted at 18 on a support 4 and carrying an armature 9, 10 and a pair of flexible strips 29, 30 carrying contacts 16, 17. The support 4 is formed with stops 27, 28 for the armature, and a pair of fixed contacts 24, 23 are adjusted so that when the armature is against the adjacent stop, each lifts its coacting contact 16 or 17 away from member 15. A permanent magnet 5 is fixed at its ends to two iron pole-pieces, as 6, shaped to form a pair of like magnetic poles 7, 8, the magnet being nearer the pole 8, and the flux path to pole 7 being restricted at 31, whereby the pull exerted by pole 8 is greater in both positions of the armature. The magnet-andpole assembly is adjustably carried in support 4 by screws 13, 14 passing through slots 11, 12 in the support. A rigid lever 19 operated by a member 230 is supported at 20 on support 4 and operates the member 15 and armature by means of a spring 21 when the force of the latter overcomes the magnetic bias, so opening contacts 16, 24 and closing contacts 17, 23. In the event of contact-welding a rigid stop 22 on member 19 bears directly on member 15. Where contacts 17, 23 only control small currents, stop 28 may be dispensed with and contact 17 rigidly carried on member 15.
