Title: An improved method of separating dust or fume from air and improved apparatus of thefabric tube filter type therefor
IPC: B01D46/04
Filed: 1926-11-22
Abstract: 273,563. Gelder, J. P. van. Nov. 22, 1926. Filtering.-Filter tubes are disposed in a casing having a dusty air inlet below the tubes and a filtered air suction connection from the space around them ; a valve closes the suction periodically and a second valve is simultaneously opened and closed at intervals to admit atmospheric air to-the, casing. A series of casings 10 are built on a dusty air inlet tunnel box 11 fitted with a worm conveyer for dust removal, and contain filter bags closed at the tops, where they are suspended by springs, and opening at the bottoms into apertures in the floor or partition separating the casings from the tunnel. Each chamber 10 is fitted with a connection 19 to a main suction pipe, I aving a. valve 20, and a connection 18 to atmosphere, similarly valved. The valve 20 is opened and closed by a link 23 reciprocated by an arm 25 with which it is connected by a pin and slot, and operated by a cam groove 43; a spring 27 on the link pressing against a stop 24 allows the lever 25 to move while the valve remains closed. The atmospheric valve 28 is actuated by a link 31 carrying a tappet 32 rotatably fixed on a slide bar 33 which works through a fixed bearing 34 and is carried by a lever 36 engaged by the lever 25 when the suction valve is closed, so that the tappet is brought opposite a striker 39 on the rotating shaft 40. When the suction valve of any one casing is closed, suction is maintained through the tubes, the tunnel 11, and the adjacent casings, and this suction is periodically interrupted by the opening of an air valve 28, collapsing the bags, which regain their shape as the air pressure within and without the tubes is equalized.

Abstract: 709,062. Autographic registers. LAMSON PARAGON SUPPLY CO.. Ltd. June 20, 1951 [Dec. 6, 1950], No. 29924/50. Class 16 A mechanism for operating the strip feeding means of an autographic register of the kind in which record strips are fed step-by-step over a writing plate by rotary members which engage the strips. comprises alternative handle or pedal means for actuating the mechanism. A shaft 2 carries a freely rotatable member 3 provided with sockets 4 to receive detachable pins 5a of a handle 5. The member 3 is integral with a dog clutch (not shown) coupled to ,the shaft in the register which drives the strip feeding means, thus actuation of the handle 5 actuates the latter. A quadrant 7 secured to one end of'a Bowden cable 11 is freely rotatable on the shaft 2 and extends into a channel-shaped member 8 also freely rotatable on the shaft 2, the quadrant 7 and member 8 being resiliently connected by a stud 9 on the quadrant and a spring 10. The quadrant 7 is rotated counterclockwise against a spring 19 by depression of a spring-urged foot pedal (not shown) connected to the other end of the Bowden cable 11, such rotation causing through a pin 3a rotation of the member 3. The shaft 2, members 3, 7, and 8 may be enclosed in a cover 1 detachably secured to the casing of the autographic register. The register may be mounted on, or form a unit with, a cash till, such that when the register is operated, the cash drawer of the till is permitted to open under the action of a spring.

Abstract: 977,799. Hose. GEORGE ANGUS & CO. Ltd. July 12, 1963 [Aug. 3, 1962], No. 30033/62. Heading F2P. A hose constituted of a textile jacket having a thin impermeable lining is manufactured by introducing into the jacket 10 a lining tube of rubber or expandable plastic 11 having a surface layer 12 which flows more readily to pressure with or without heat than the tube 11 and subjecting the combination to internal pressure and if necessary to external heat to cause the surface layer 12 only to exude through the interstices of the jacket to the exterior of the tube as short spikes and by forming an external surface layer over the textile jacket by smoothing down the short spikes or by applying rubber or plastic material to the spaces between the exudations. The jacket is preferably woven but may be knitted or braided or may have warp yarns with a wound helical weft not interlacing with the warps. The lining tube and layer may be of different materials or of the same materials in different states e.g. in different cross-linked or polymerized states or containing different amounts of accelerator. A textile reinforcement may be used in the lining by being wrapped around the outer surface of the lining or by inserting a cloth with the flowable material calendered to its surface, as the surface layer or between the surface layer and the textile jacket or between the lining tube and the surface layer or within the lining tube. The lining and surface layer tubes may be made by extrusion.

Abstract: 150,577. Jackson, W. J. Mellersh-, (Novelty Products Co.). Dec. 2, 1919. Clothes-pegs; clips, pivotedjaw.-A double-ended clothespeg comprises two rigid jaw members 2, 3, preferably of wood, clamped together by a resilient wire spring 4, and formed with diverging fulcra 18, 19, so that inward pressure on either pair of diverging portions causes the members to rock on the adjacent fulcrum and opens the jaws at the other end of the peg. The wire spring 4 extends through transverse openings 5 in the adjacent faces of the jaw members, the two ends of the wire being curled at 7 so as to extend downwards at 13, and finally lapped round the jaw members at 8, 9. In use, the article of clothing may be folded over the line and the peg employed to clamp it thereto in the ordinary manner, or one end of the peg may be attached to the article and the other end of the peg suspended from the line, for which latter purpose are provided apertures 21, 22 in the jaws, the aperture 21 being of round section to engage wire clothes lines, and the aperture 22 being shaped to accommodate a woven clothes line or rope. In the form of peg shown, the clamping-ends 8, 9 of the wire spring are disposed nearer the lower end of the peg so that the resilient tension on an article held between the lower jaws is greater than the tension of the jaws at the other end on the clothes line.

Abstract: The invention comprises as new compounds having pharmacological effects ditartrates of the formula <FORM:0717476/IV (b)/1> in which R1-R7 are alkyl radicals of 1 to 3 carbon atoms.  They are obtained by reacting the corresponding diammonium hydroxide compounds with tartaric acid.  The diammonium hydroxide compounds may be obtained by reacting the corresponding diammonium halides with silver hydroxide or with anion exchangers or by treating the methosulphates with dilute sulphuric acid and then with barium hydroxide.  In an example N : N : N1 : N1 : 3-penta-methyl-N : N1 - diethyl - 3 - aza - pentylene - (1 : 5)-diammonium dibromide in water is shaken with a small excess of silver oxide in water, the product filtered from the silver bromide produced and the aqueous solution treated with d-tartaric acid in water to yield N : N : N1 : N1 : 3-pentamethyl - N : N1 - diethyl - 3 - aza - pentylene-(1 : 5)-diammonium ditartrate. The same product is also obtained when the solution of the diammonium dibromide is allowed to flow through a column of an anion exchanger prepared with 2N caustic soda solution and the aqueous eluate treated with tartaric acid.

According to the invention, the machine is characterized by screws 63, 64 carried by a shaft 61 for limiting the vertical depth of feed of the slide, a bush 53 having a roller 52 to engage a cam slot 51 in the column in order to displace the bush, disengage the gears 14, 15 and withdraw an indexing catch 54 from a recess 55, a spring-loaded ratchet lever 58a so connected through gearing 58, 59, 60 as to index the head 10 near the end of the upstroke of the slide by contact with a projection 57 on the column, and means 56c on the bush 53 to operate a push-button control 56a for the motor which drives the gear 15 through a universally-jointed telescopic rod 66. The slide is balanced by a weight 68 in the standard and arranged above a vertically-adjustable work-table. After indexing, as the head is lowered by a feed-lever, a roller 52 on each side of the bush travels down the portion DC of the respective slot 51 while the ratchet lever 58a is rotated by its spring relative to the gear 58. The portions CB of the slots re-engage the gear 15 with another of the gears 14, locks the head with the catch 54 and releases the button 56a to re-start the motor.
