Title: Improvements in conveyors or mechanical feeding apparatus
IPC: B65G25/00
Filed: 1940-06-20
Abstract: 540,626. Step-by-step conveyers. BEASLEY, H. H., and BEASLEY. FRENCH & CO., Ltd. June 20, 1940, No. 10649. [Class 78 (i)] A plurality of containers &c. 1 are pushed simultaneously and intermittently along guide bars by fingers 4 projecting upward from rods 5 given an up and down and to and fro motion in a closed path. The rods 5 are mounted in parallel location on cross shafts, the ends of which may move in rectangular cam grooves arranged one at each end of each shaft. Means for pulling the shafts along said cam guides may consist of links connecting the ends of the shafts to bent cranks rotated through gearing from a power shaft. Alternatively, the rods 5 may be connected by pitmans 26, 28 to two rotating cranks 25, 27 located respectively laterally of and beneath the rods 5. Said cranks and pitmans may be substituted by cams and spring retracted members. The guide bars along which the containers slide may be of stepped formation on top and may be hollow to be heated or cooled by fluid flowing within. The apparatus may have a drip tray located below the containers.

Title: Improvements in oil burning space heaters
IPC: F24C5/02
Filed: 1956-04-07
Abstract: 794,149. Vapour burners, MILLER, H July 18, 1956 [April 7, 1956], No. 10666/56. Class 75(1) In an oil burning space heater in which the lower portion 8 of a chimney 3 extending vertically from the top of a fuel container 1 forms the combustion chamber and in which a pipe 13 returns a portion of the combustion products from a point above the combustion chamber to the fuel container to form a mixture of combustion products and fuel vapour, the chimney is formed by an upper cylindrical tube 4 and a lower perforated combustion portion 8 and a filling aperture 2 in the top of the container is closed by a hinged cap 16 formed as a regulator for controlling the supply of air to the container. The air regulator 16 comprises a flanged cap 18 and a spring loaded slotted plate 24 rotatably mounted on a pin at the centre of the cap 18 and adapted to cover apertures 19 in the cap. Each aperture 19 is formed in an embossed portion 21 of the cap and a groove 22 extends from each aperture to the edge of the embossed portion 21 to provide a reduced air supply when the regulator is closed. An increased air supply may be provided by keeping the plate 24 out of contact with the cap by a pip 23 provided on the cap. The chimney is fitted into a neck in the top of the fuel container and a butterfly clamper is pivoted in the neck. The top of the chimney can be closed by a hinged cap 5. Heated gases from the chimney are deflected by a disc 6 supported on arms 7. The return pipe 13 is connected to the chimney by means of a cast iron elbow 14.

Title: A non-return valve
IPC: A62B18/10
Filed: 1962-03-20
Abstract: 1,004,032. Fluid-pressure control valves &c. E. P. V. R. GODEL. March 20, 1962, No. 10698/62. Heading F2V. [Also in Division A5] An exhaust valve primarily for a respiratory mask for high altitude use is associated with a pressure-sensitive device connected to the supply source so that the opening pressure is dependent on the supply pressure, but also having means for preventing communication between the mask and atmosphere if the supply pressure falls to atmospheric. In one form the valve assembly shown in Fig. 1 is fitted into an aperture in the wall of a face-mask the wall being gripped between a flange 2 and the adjacent flange on a cover member 4, and exhaled air passes through orifices in the cover 4, between a valve seating 13 and a plate valve 11 to a chamber 12 and out to atmosphere through apertures 5. The valve 11 tends to be held closed by expansion of a bellows 27 which bears upwards against it owing to internal pressure of gas received through pipe 35 connected to the supply. Thus any change in the pressure of gas fed into the mask is balanced by a corresponding change in the thrust exerted on the valve by the bellows. If, however, the pressure of the gas supply falls to atmospheric pressure the valve 11 is still maintained closed by a light spring 36 connected between the bellows and the valve. In another embodiment described with reference to Fig. 4 the natural resilience of the bellows is employed to hold the valve closed under these conditions. This may be adjusted by screwing the tube 21, carrying the bellows 27, towards or away from the seating 6. In this form the tube 21 is additionally employed to supply gas to the face-mask, an inlet valve 51 being opened at each inhalation of the user.

Abstract: 1,137,742. Tobacco smoke filters. UNION CARBIDE CORP. 11 March, 1966, No. 10747/66 Heading A2C. [Also in Division C3] A tobacco smoke filtering element comprises styrene polymer fibrils, or a stretched composite monofilament comprising a mixture of two or more incompatible thermoplastic resins, one of which is a styrene polymer, said fibrils having diameters within the range 0.1 to 5 microns, wherein the fibrils or the monofilament is disposed within an enclosure adapted to allow the passage of smoke through the filtering element, whereby objectionable constituents are removed from the smoke. The styrene polymer may be a polystyrene homopolymer or a copolymer containing at least 50% copolymerized styrene, e.g. a copolymer of acrylonitrile and styrene. The fibrils are present in an amount of at least 1% by weight of the filter. The composite monofilament, which may be made by extruding a mixture of the fibrils with the incompatible thermoplastic polymer, contains 10-45 parts by volume of styrene polymer and 55-90 parts by volume of the thermoplastic polymer. The thermoplastic polymer is preferably polyethylene, but may also be e.g. polymethylmethacrylate, polyvinyl acetate, polyvinylbutyrate, polyvinylchloride, nylon, polytrifluorochloroethylene, copolymers of styrene, copolymers of vinyl halides and vinyl esters, and copolymers of vinylidene halides and vinyl halides.

Abstract: 297,446. American Blower Corporation, (Assignees of Morse, C. T., and Hogan, E. L.). Sept. 22, 1927, [Convention date]. Density separators.-Dust-laden gases, such as the gases from the blast furnace 1, are led to the separator 3 in which the heavy dust parrticles, are separated, while the gas with a quantity of fine dust passes through the pipe 7 to the disintegrator 8. Water is sprayed into this machine from the pipe 9 and the moistened gas passes through the pipe 10 to the separator 11. This has a closed conical casing 12 with a tangential inlet 15 anc a spiral track 16 which decreases in width from the inlet until it terminates in a point 18 at the dust outlet 17. The water and dust are deposited on the track 16 and pass downwards to the vessel 13; the clean gas passes out through the central tube 14. The heavy dust from the first separator 3 drops into the container 5 and is returned by the conveyer 6 to the furnace 1.

Abstract: 701,305. Making stem lugs for cycles. PHILLIPS & CO., Ltd., J. A. April 24, 1952 [May 8, 1951], No. 10756/51. Class 83 (2). [Also in Group XXXI] A method of manufacturing stem lugs for cycles or motor cycles from prefabricated pressed metal parts comprises forming a jaw clip 12 and a tubular spigot 13 on one part 10 and a tubular socket 14 and cap lug 15 on the part 11 and welding or brazing the spigot into the socket. The part 10 is formed from an elliptical blank which is drawn with a central spigot closed at one end and having an open mouth surrounded by an elliptical flange. The flange is clipped to leave two wings 22 the ends of which are pressed into channel shaped ears 25 (Fig. 7). The remainder of each wing is then bent to form a cylindrical clip 12 (Fig. 1). The ears are punched with holes for a clamping bolt. The part 11 is formed from a diamond shaped blank the apices of which are clipped to provide curved corners. The blank is folded about its short diagonal and drawn into a hood shaped pressing having a domed apex. This apex is flattened (Fig. 11) and the sides of the pressing clipped at 35. The edges 35 are then drawn together and brazed or otherwise united to form a cylindrical socket 14 and cap lug 15. The socket 14 is gapped at 43. A hole is made in the end of the spigot 13 to facilitate the brazing or welding of the spigot in the socket 14. The spigot may be given a part-cylindrical depression so that it will seat against the cylindrical wall of the stem tube 16.
