IPC: F42B27/08
Filed: 1935-12-10
Abstract: 470,179. Fire - extinguishers. HAIMANN, E., and IMPA EXPORT UND VERSANDGES. Dec. 10, 1935, No. 34173. Convention date, Dec. 11, 1934. [Class 47 (ii)] A fire-extinguishing grenade comprises a frangible casing 1 containing an extinguishing powder 4 and closed by end caps 6, 7, preferably of cardboard, which are tightened on the casing by spring washers 8 on a supporting rod 2. A cardboard, celluloid, or like tube 11 arranged parallel to the rod 2 and fitted on the caps 6, 7 houses fuses for igniting the explosive charge 5, which is enclosed in a cartridge 10 slidable on the rod 2 and tube 11 and embedded m the powder 4. A quick match 13, passing through a hole 15 in the tube 11 to a detonator 14 for the explosive, is connected to an inflammable ribbon 12 normally protected by a removable cover 24. A second quick match 23 is connected to a time fuse 22 connected to a friction igniter 16 adapted to be ignited by a pull on a cord 17. The latter, with its operating ring 18, is housed in a recess 19 in a handle 3, a slide ring 20 with an aperture 21 normally covering the recess. The handle is held against rotation on the rod 2 by a plate 25 provided with a suspension hole 26. The angle of distribution of the powder 4 can be varied byadjusting the cartridge 10 along the rod 2 before the casing 1 is charged, the fuses 13, 23 having slack to permit this. If the cartridge is conical, a conical discharge of the powder may be obtained. The Specification as open to inspection under Sect. 91 comprises also a construction, Figs. 4 and 5 (Cancelled), wherein an extinguisher comprises a casing 31, of the shape shown, provided with a filling opening closed by a cover 33, and carried by a rod 34. The latter carries a cartridge 35 comprising a friction igniter 38 and an explosive charge 36 between packings 37. The extinguisher is suspended from a hook 46 by an eye member 43, the limbs 44 of which are embedded in fusible solder 45 in a cup 42 carried by the hook. A cord 40 connected to the igniter 38 is coiled several times round a roller 47, and made fast to the hook 46. When the solder 45 melts, the extinguisher falls, and uncoils the cord 40. When the latter is fully extended, it fires the igniter 38, exploding the charge 36. The charge may be exploded electrically, by arranging that the limbs 44 close an electric circuit when the solder melts. This subject-matter does not appear in the Specification as accepted.

Title: Air Filter with Filter Cleaning Apparatus
IPC: B01D46/26
Filed: 1967-07-31
Abstract: 1,190,959. Gas filter. MICROTRON CORP. 31 July, 1967 [1 Sept., 1966], No. 35142/67. Heading B1T. In a rotary drum ventilation air filter (Fig. 1, not shown), the drum 20 is rotated by an electric motor (23) at timed intervals or when clogging is detected, and during rotation a suction nozzle 24 is moved stepwise across the outer, upstream filtering surface of the drum by a self-acting or manually controlled doubleacting pneumatic ram. The nozzle remains in each of a series of overlapping positions during one drum revolution, then moves a step to the left, and on reaching the leftmost position causes the drum rotation to cease and initiates a repetative stepwise motion back to the right-hand starting position. Nozzle 24 is mounted on a carriage (30) running on a track 31 in a housing 32 and mounting cylinder 35 of the ram. Piston (39) of the ram has a piston rod 40 extending from one or both (as shown) ends of the cylinder to carry latch assemblies 41. A pneumatically actuated valve 55 delivers compressed air in turn to each end of cylinder 35, whereupon the cylinder moves while the piston is fixed by one of its latches 44, 45 bearing on the housing and or engaging one of respective notches R1, R2, R3, or (L1, L2, L3) depending on direction of movement. When cylinder 35 reaches the end of its rod 40 a plunger 80 or 81 engages latch post 42 or 43 to reverse valve 55, whereupon the other end of cylinder 35 is pressurised and the weight of the carriage, and its adjustable frictional engagement with a bar (115) (Fig. 11, not shown), causes it to remain stationary while the piston and latches are moved forward, notches R1 &c. being shaped to allow this (Fig. 6, not shown). When the nozzle is moving to the left, each step is initiated by a cam 50 on the rotating drum engaging a lever 51, which pivots actuator 72 (Fig. 2 not shown) to effect the first movement of valve 55. When the carriage reaches the leftmost position, drum motor (23) is automatically stopped by switch (5), latch rod 100 and reversing rod 84 strike the end of housing 32, whereby the latch 45 is rendered inoperative and the latch 44 operative, while the connections between valve 55 and its alternative sets of actuators are adjusted, whereafter both plungers 80 and 81 are effective instead of 81 alone. The carriage then moves rightwards in steps without cam 50 doing anything. Plunger 71 is accessible for manual operation of valve actuator 72, if desired. Alternatively valve 55 is controlled by a short period timer under control of a long period timer which also controls the drum movement and nozzle suction means (26). Suction means (26) could alternatively be controlled by downstream pressure switch (141) which controls restart of drum motor (23).

[Also in Divisions C4 and H1] A tunnel cathode, which may be used to replace the Corona brushes used in air particle ionizers in precipitors, comprises a monocrystalline base 21, see Fig. 2, e.g. of W, Mo, Si, Ge, Bi, Au, Ni, Fe, a thin film monocrystalline insulating barrier 22, e.g. of Al 2 O 3 , MgO, SiO, ThO 2 , TiC, BaS, disposed on top of the base, and a monocrystalline semiconductor omitter layer 23 having an electron density lower than that of gold, Si, Ge, ZnS, GaAs, disposed on top of the barrier 22. The cathode is operated with a potential bias applied between the base 21 and the emitter 23. The insulating barrier and emitter layer may be respectively epitaxially disposed on the base which itself may be epitaxially disposed on a monocrystalline insulating substrate 27 e.g. of sapphire, magnesia, beryllia or magnesium aluminate spinel. A monocrystalline base of tungsten may be deposited on a sapphire or magnesia substrate by hydrogen reduction of WF 6 , and the crystallographic orientation of the base metal may be controlled. Epitaxial deposition of monocrystalline molybdenum on a substrate 27 may be carried out by pyrolysis of molybdenum hexachloride in a hydrogen atmosphere. Monocrystalline Al 2 O 3  may be formed on W or Mo base 21 by heating base 21 and substrate 27 in a vacuum to 800‹C and depositing the thin film of Al 2 O 3  using electron beam vacuum techniques or by chemical vapour phase deposition from gaseous aluminium-alkyl mixed with CO 2  and hydrogen. A monocrystalline semiconductor emitter layer of Si may be epitaxially deposited on Al 2 O 3  by hydrogen reduction of SiCl 4  or HSiCl 3 , or by thermal decomposition of SiH 4 . During the vapour phase deposition of emitter 23 a resistivity changing dopant may be introduced so that by controlling the concentration of the dopant as the emitter thickness increases, a graded resistivity profile may be produced.
