Title: Combination of a door frame a door and a door latch
IPC: E05C19/16
Filed: 1975-11-12
Abstract: 1530591 Magnetic door latch TIMBER RESEARCH & DEVELOPMENT ASSOCIATION 12 Nov 1975 [12 Nov 1974] 48940/74 Heading E2A A door (11) is held in its correct closed position by a latch comprising a pair of magnets 14, 15, the magnet 14 being slidable vertically in a bore 16 in the top surface of the door (11) and the magnet 15 being fixed in a bore in a lintel of the door frame (12), (or vice versa) so that the magnets 14, 15 are in alignment when the door (11) is closed centrally in the frame (12) the magnet 14 sliding under the action of the magnetic attractive forces into engagement with magnet 15. The door (11) may be a door opening in one direction only but in the embodiments illustrated the door (11) is a swing door. In the embodiment of Figures 1, 2 the magnets 14, 15 are button magnets, with opposite poles on approximately semicylindrical sections on either side of a slot 17. The slidable magnet 14 is located in bore 16 on a central pin 21 (or alternatively on a pair of non-ferrous vertical pins in side slots in the magnet). If the door swings rapidly there will be insufficient time to lift the magnet 14, but if the door closes slowly like poles of the magnets will first repel each other, and then unlike poles will attract each other to provide a final closing force to the door. In opening the door, the magnetic attractive forces between unlike poles first resists such opening but once the door has started to open the repulsive forces between like poles assists such opening. In the arrangement of Figure 3 the magnet 14 slides in a cup 23 which is itself slidable vertically on the pin 21 in the bore 16, a compression spring 24 urging the magnet against stops (not shown). On either side of the magnet 15 in the lintel is a button 25 which cooperate with bevelled edges 26 of the magnet 14 as the door is closed; the buttons 25 also prevent the door being opened unless a substantial thrust is applied thereto. The buttons (25) can have a steeper curved head away from the magnet (15) (see Figure 4, not shown) or vice versa. Where buttons (25) are used, conventional flat magnets can replace the button magnets. As an alternative to the button a bent leaf spring (28) is pinned to the frame (see Figure 5, not shown).

Abstract: 1,190,786. Feeding sheets. WEYERHAEUSER CO. 1 Nov., 1967 [2 Nov., 1966], No. 49620/67. Heading B8R. A stack 10 of veneers is conveyed by transfer members 11 sliding on a track 13 to a position beneath a vacuum separator 34. Members 11 are reciprocated by a cylinder 14 attached to the members by a chain 15 running around pulleys 16 and 17. The stack is arrested against stop 20 whereupon limit switch 21 actuates cylinder 24 to raise elevator 18 until the top of stack 10 is at a predetermined height. Limit switch 25 detects the top of stack 10 and stops elevator 18. Vacuum separator 34 removes individual veneers until switch 25 is no longer tripped whereupon elevator 18 again moves upwards. Upward travel of elevator 18 releases a limit switch which causes members 11 to return to their outer position. Mechanism 34 transfers the separated sheets to a horizontal vacuum transfer mechanism 35 which deposits them on to conveyer 36. When the stack is depleted to one sheet the plate 31 is biased by a spring such that it rises above rollers 19, switch 40 is tripped, lowering elevator 18 and leaving the last veneer on vacuum bed 41. Lowering of the elevator causes plate 31 to be pulled below rollers 19 and a limit switch to be tripped actuating transfer members 11 to move another stack on to the elevator, assisted by rollers 19.

Title: Particulate electrode cells and their use

Filed: 1975-12-22
Abstract: 1514979 Fluidized bed electrodes PAREL SA 21 Dec 1976 [22 Dec 1975] 52494/75 Heading C7B The size distribution of electroconductive particles constituting a particulate electrode of an electro-chemical cell is controlled by subjecting particles extracted from the electrode to elutriation, in which the flow of elutriating fluid is such that particles larger than a predetermined size settle against the fluid flow, while the smaller particles carried along by the elutriating fluid are returned to the electro-chemical cell after separation, if necessary, from the fluid. Preferably, elutriation of the extracted particles is controlled automatically, e.g., by means of electronic or magnetic detectors, so that the total volume of particles constituting the electrode remains essentially constant. Magnetic detectors are preferred when the particles are ferromagnetic (e.g. Fe, Ni or Co). Typically, electronic probes the outputs monitored by LC oscillator circuits are spaced 25 mm. apart are used to establish the minimum and maximum heights of the electrode. Alternatively, the size of the electrode may be controlled by monitoring the pressure at the base of the particulate electrode. The elutriating fluid will generally be liquid, and is advantageously the electrolyte of the cell, in which case no particle separation from the elutriating liquid is necessary. The elutriation vessel or column may be vertically disposed, 1-4 m. in height and 15-40mm. diameter, into which the particles are fed at a point above e.g. 0À3 m. above that which the fluid is introduced. Preferably, the particles enter the column at least 30 degrees to the horizontal; the particle inlet pipe may suitably have a diameter of about 15 mm. The column diameter at and above the particle inlet may be greater than that in the lower portion of the column. In an embodiment, the cathode compartment 1 contains a fluidized bed cathode (16) Fig. 7 (not shown) and an outlet 2 sited in the region of turbulence of the cathode compartment through which particles are fed to the elutriating column 3. Catholyte from 11 is fed to 3 via a flow-rate valve 5; the smaller particles are carried up through 3 and returned to the cathode, the larger particles descend through regulating valve 6 preferably a pinch valve to tank 8. Outputs from inductive proximity detectors (17) Fig. 7 are sensed by control system 7 which in turn controls valve 6 so that while particles enter 3 continuously, 6 is opened to remove product from the column and to control the cathode bed height.
