Title: Carpet for athletic playing fields
IPC: E01C13/04
Filed: 1973-06-23
Abstract: 1442806 Water-pervious coated needled laminates J P STEVENS & CO Inc 23 June 1973 24721/73 Heading B5N [Also in Divisions A5-A6] A liquid water-pervious carpet for surfacing indoor and outdoor athletic surfaces comprises at least one batt of fibres of length 1¢-6 inches needled through a liquid-water-pervious, non-water-absorbent membrane, e.g. a woven or non-woven polypropylene scrim, to form a non-crimped pile layer on the face of the batt from which needling takes place, at least the pile having applied thereto a binder which coats the individual fibres but does not form a continuous layer. Either a second fibrous carpet layer may be needled, or a reinforcing cellular polyvinyl chloride backing may be applied, to the other face of the membrane. An elastomeric rubber, polyurethane or polyvinyl chloride backing may be applied. The carpet may be affixed to a series of wood, hardboard or polyurethane foam panels which can lock together to form a portable tennis court, or plastics backing layers may be provided with a regular waffle pattern to facilitate adhesion to a surface by suction. Fibrous batts are preferably applied to the membrane with their fibres lying across the machine direction. If two fibrous layers are used, the bottom layer may be of polypropylene and may be embossed by heated rollers to form parallel drainage grooves or channels after the carpet has been made; the top layer may be thicker and may be of lightresistant fibres, e.g. acrylic, although other fibres are specified including acrylic-polypropylene mixtures. If only one fibrous layer is used, it may be a thick polypropylene or acrylic batt. The binder may be applied to the face or to the face and back, of the needled structure by kiss-coating, spraying or saturation, followed by application of pressure to ensure penetration of at least the pile layer. Specified binders, which approximate to the rebound characteristics of a clay tennis court, are crosslinking ethylene-vinyl acetate and ethyl acrylate-acrylonitrile dispersions and polyurethane.

Abstract: 912,075. Automatic character reading. DE STAAT DER NEDERLANDEN TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEUR - GENERAAL DER POSTERIJEN TELEGRAFIC EN TELEFONIE. July 22, 1959 [July 24, 1958], No. 25133/59. Class 106 (1). In a character reading apparatus the characters are specially shaped so as to be composed of certain ones of three vertical bars and they are associated with key marks to gate out signals from corresponding character bars. In the form of Fig. 1 there are key marks above and below the characters to gate out certain ones only of the signals derived by sensing the top and bottom halves separately. An output is only produced when a key mark coincides with a character bar in the corresponding position of the adjacent upper or lower half. In the form of Fig. 2 there are three key marks for each character but in characters 6, 8 and 9 only two correspond with the bars of the character. The top and bottom halves of the character are again sensed separately and signals are produced where a bar of the character coincides with a key mark. In both forms the arrangement is such that each character produces two signals in six positions. In the form of Fig. 1, there may only be five positions. A checking arrangement may be applied to the signals to ensure that two and only two signals are produced for each character.

Title: Apparatus for the graphite lubrication of cylinders operating under steam
IPC: F16N15/02
Filed: 1951-10-29
Abstract: 714,708. Lubricating. HAYES, D. H., HAYES, I. D. B., and HAYES, G. G. Jan. 26, 1953 [Oct. 29, 1951], No. 25280/51. Class 12(3) Apparatus for lubricating the cylinders of steam hammers or other steam-operated units with colloidal graphite comprises a storage vessel 12 containing a suspension of colloidal graphite in water, the vessel being connected by a pipe 11 to a source of gas pressure, .for example, a cylinder 10 containing nitrogen under high pressure, and being also connected by a pipe 18 to a steam pipe line 19 leading to a cylinder to be lubricated. The pipe 11 is provided with a pressure-reducing valve 13 so that the pressure in the storage vessel 12 is slightly higher than the steam pressure in the line 19, and is also provided with an isolating valve 14 and a needle valve 11a, for use if a fracture should occur in the pipe 11. The graphite supply line 18 has a needle valve 20, a non-return valve 22, a pressure release valve 21, and a stop valve 23. Branch lines 26 may be provided where several units are to be lubricated. In the case of the lubricating of a steam hammer cylinder a diaphragm-operated valve 28 is controlled from a pilot valve 29 located under the hammer driver's platform 30, the arrangement being such that when the driver is on the platform 30 his weight causes the platform to be lowered to close the valve 29 whereby steam is prevented from passing through the pipe 31 to close the valve 28. The graphite is then free to pass from the pipe 18 to the pipe line 19 by way of an injector valve 25. When the driver leaves the platform 30 valve 29 is opened by steam pressure which also acts to close the valve 28. The storage vessel 12 is provided with a float-operated electric alarm 33, 34, 35 which indicates when the graphite falls below a certain level.

[Also in Divisions A5, Fl, F4 and G1] A fluid mixing device comprises a mixing chamber having an axial inlet 212 for a pressure fluid, an intake conduit 216 at the inlet end adjacent the pressure inlet, and a sharpedged outlet portal, the sharp edge lying in a plane perpendicular to the chamber axis (as shown, the plane 220); the chamber has a cylindrical surface extending towards but not overlapping the pressure inlet. The core member 228 may be axially adjusted (as shown, by screwing) to vary the volume of the mixing chamber whereby standing waves may be set up at frequencies of 1-6 c.p.s. and 14,000 c.p.s.; these may be reinforced by mechanical, piezo-electric or electro-magnetic transducers 229, 231. Different adjusted positions of the core member 228 will produce either maximum negative pressure in, or maximum volume flow through, the intake 216. In another embodiment, the member 228 may be slidable and the sharp-edged outlet may be the intersection of two conical surfaces (see Figs. 2 and 3 not shown). The device may be used for mixing liquids or gases, or producing suspensions of powder in gas, or as an aspirator or vacuum pump, or for atomizing liquids especially for the injection of liquid fuel into combustion chambers of engines turbines or furnaces; examples of dimensions and flow rates are given. A multi-stage mixing device, Fig. 6, may be used to mix a second liquid fuel, water or other additives with the fuel-air mixture, the mixture ratios being controlled by adjustment of the sizes of the mixing chambers.

Title: Method and apparatus for locating effective operand of an instruction

Filed: 1974-06-07
Abstract: 1434702 Addressing BUNKER RAMO CORP 7 June 1974 [7 June 1973] 25464/74 Heading G4A An instruction includes an operation code, an address mode tag and an operand, the address mode tag being decoded to provide the entry point in a microprogram memory for a microprogram to control the obtaining of the operand for the mode indicated by the tag. As described an instruction includes a first word having 5 bits representing the OP code, 3 bits representing one of eight possible address modes and a second word having 8 bits which may represent for example the operand or the direct or indirect address of the operand. Initially with microprogram register UPC (Fig. 1) reset to zero, read-only microprogram memory 12 is addressed at the start of a fetch microinstruction which results in a micro-order signal F1 from decoder 14. This results in the count in program counter 28 being incremented in arithmetic unit 24 and entered into address register 18. The register UPC is then incremented which results in a control signal F2. This enables read out from main memory 10 of the instruction stored at the address held in register 18, the contents of which are also incremented and re-entered into the register 18. The next control signal F3 results in the three address mode tag bits of the read out instruction being decoded and transferred to register UPC to cause branching to the correct address mode microprogram. The starting address of the execution mode microprogram is fed to temporary register 40. During execution of the address mode microprogram the second word of the instruction is read out from the main memory and used to obtain the instruction operand after which the contents of the temporary register 40 are transferred to register UPC to branch to and perform the execution mode microprogram. The last micro-order of this microprogram causes reset of the register UPC to zero.
