  • Inflatable receptacle
    Patent number: 4384603
    Abstract: An inexpensive, readily handled receptacle for use in the bulk impregnation of timber by vacuum impregnation is made of flexible fluid-impermeable material and, over parts of its walls, is of double thickness to form closed pockets that can be inflated to form a container of rectangular shape hinged along one of its side faces to provide a sealable opening for loading and unloading. The pockets have a valve for inflating them with air; the receptacle has inlet and outlet ports for evacuating the receptacle and introducing impregnant. Preferably, the receptacle is supported in a two-part rectangular frame hinged along one side face.

  • Methods of rolling wire rods or bars
    Patent number: 4382376
    Abstract: In the reduction of the cross section of wire, rods or bars by rolling, the work material is placed under longitudinal compression in a roughing block and/or in an intermediate block and is only under tension in a finishing block. By this means, the ends of the work material are thinned prior to entry into the finishing block, instead of being thickened as they would be if the work material were under tension in the roughing and/or finishing block. Compensation for this end thinning is effected in the finishing block due to the rolling under tension, so that wastage due to cropped thickened ends is avoided.

  • Non-sticking ply end turn-over bladder and method of manufacture thereof
    Patent number: 4381331
    Abstract: The bladder has at least a portion of its outer surface comprising a fabric layer of cords partially embedded therein so that such cords project slightly above the rubber surface. The article is manufactured by calendering a fabric layer of cords on one side only with a coating of uncured and unvulcanized rubber, applying the layer to the bladder material with the rubber coated surface in contact therewith, and heating the article so formed to cure the rubber coating. The curing causes some of the rubber coating to flow between and over the outside surfaces of the cords. This excess rubber is removed by abrading the article so as to expose the cords. The abrading removes some of the cured rubber between the cords so that the cords project slightly above the surface of the rubber substrate.

  • Apparatus and method for detecting a fraction of a gas
    Patent number: 4380167
    Abstract: An apparatus is provided for detecting the quantity of a specific gas hereinafter simply called "gas" in a carrier gas when water vapor is present. The gas and the carrier gas are passed through a whistle chamber which produces a resonating frequency. The resonant frequency changes as a function of the fraction of the gas, temperature and water vapor. An output signal is produced which is a function of the resonant frequency. A correction device senses water vapor and temperature and produces an output signal which is a function of the water vapor and the temperature. A receiving means receives the output signals and produces a resultant signal which is a function of only the fraction of the gas.

  • Spring rail fastening system
    Patent number: 4379521
    Abstract: A rail fastening system for securing rails to rail ties in which an elastic fastener is used. The fastener has one portion which lies on the rail flange and a second portion which seats within a support secured to the rail tie. The fastener comprises a base portion which seats within the support and two tapered arms which are curved over the base so that the free ends of the tapered arms lie on the rail flange. The support is located adjacent the rail flange and a locking element fits between the rail flange and the support and is shaped to interfit with the support in a wedge-like relationship such that longitudinal rail movement acting on the locking element is translated into a lateral force to prevent longitudinal rail movement.

  • Structural joints
    Patent number: 4378173
    Abstract: A structural joint suitable for a frame member for furniture, e.g. a leg for a work bench, comprises two tubular members 10, 11 slidable one inside the other. Each member 10, 11 has a longitudinal slot 13 through which a wing nut 16 is passable. The members are secured by engaging a screw 17 in the nut 16 which is so long that it cannot fully rotate inside the inner member 11. Preferably, the slot 13 has enlarged portions 14 which alone can pass a boss of the nut 16.
