Title: Improvements in coupling devices for lubricators
IPC: F16N21/04
Filed: 1928-12-14
Abstract: 302,325. Gits, R. J. Dec. 14, 1927, [Convention date]. Couplings, disconnectible; with valves. -A lubricator, of the kind comprising a reservoir 1 provided at one end with a nozzle 6 through which lubricant is ejected by a piston 5 upon rotation of a piston - rod 3, threaded in a cap 2 at the other end of the reservoir, and handle 4 rigidly secured thereto, is connected to the usual nipple 20 on the part to be lubricated by means of a coupling sleeve 14 which is provided at its outer end with a square hole 18 adapted to slip over a square head 19 on said nipple and engage the under-surface thereof upon relative rotation of the two parts. The sleeve 14 has a screwthreaded connection with the nozzle 6 and houses a slidable bushing 15 which has an axial bore therethrough in registry with the bore 7 of the nozzle, and the face of said bushing adjacent the convex end 12 of the nozzle 6 is formed with a concave portion 34 to engage therewith while the opposite face is countersunk to hold a gasket 16. The sleeve 14 is also provided with a pair of pins 28, 29, mounted in the lower end thereof and positioned so as to engage the corners of the head 19 and prevent relative rotation between the two parts of more than one-eighth of a revolution, while the bores of both the nozzle 6 and nipple 20 are normally closed by spring-pressed balls 10, 24 respectively. In operation, the coupling sleeve is slipped over the nipple 19 until the outer face of the latter abuts against the gasket of the bushing 15, and it is then rotated by means of the handle 4 until the pins 28, 29 contact with the said head. Further rotation of the handle will first cause the reservoir 1 and the nozzle 6 to move relatively to the sleeve 14 until the end 12 of the nozzle contacts with the seating 34 in the bushing 15, after which the piston 5 will be moved longitudinally in the reservoir to eject lubricant therefrom. The lubricator is removed from the nipple by rotation of the handle in the reverse direction. Such rotation will first turn the nozzle 6 relative to the coupling sleeve 14, thus loosening the sealing connection with the nipple 20, after which the sleeve 14 is rotated relatively to the nozzle 6 by means of a torsion spring 33, positioned between the two parts as shown, until a spring-pressed plunger 31 on the nozzle contacts with a stud 30 on the coupling sleeve; further rotation of the lubricator will then bring the hole 18 into alignment with the head of the nipple.

Filed: 1968-05-17
Abstract: 1,260,863. Making composite sheets and tubes. NATIONAL RESEARCH DEVELOPMENT CORP. 14 May, 1969 [17 May, 1968; 6 Aug., 1968], Nos. 23586/68 and 37537/68. Heading B3A. [Also in Division C7]  Thin sectioned metal articles e.g. sheets, tubes or ferrous strip are made by directing a gas stream containing particles of a metal compound on to a substrate to form a layer of at least partly reduced metal. The layer while still hot is preferably hot worked either before or after stripping from the substrate which may be of ceramic, vitreous, asbestos or steel or Cu coated with a graphite releasing agent. The preferred process comprises feeding iron oxide particles with or without alloying additions such as Mn and Ni as ferroalloys or oxides into a gas stream of H 2  and/or hydrocarbons, carbonaceous fuel or natural gas or a mixture of H 2 , hydrocarbons and CO at 1000-2500‹ C: and depositing a layer of iron on a reciprocating continuous band. The layer 0À01-0À5 in. thick is passed through a tunnel furnace at 1000-1200‹ C. in a reducing atmosphere to complete the reduction. The layer after cooling to the required working temperature is hot-rolled or compacted preferably under a reducing or inert atmosphere. Prior to hot rolling the layer may be coated with metals by powder or liquid spraying and then rolled to form coated products. Alternatively different layers of metals may be deposited successively using different metal compound particles in the gas stream. As shown in the Fig. 1 preheated oxide particles are sprayed in a gas jet 3 into an endless stainless steel band 9 cooled by sprays 13. The layer of powder is finish reduced in chamber 17 and directed to rolls 26. Tubes may be made by depositing on a mandrel or on the inside of a cylinder.

Abstract: 1,239,820. Control systems for thermal storoge heaters. D. R. MORRISON. 7 Nov., 1969 [7 Aug., 1968], No. 3777.5/68. Heading H2H. During the discharge period of a storage heater, charged normally during off-peak hours, the energy stored, as measured by the temperature sensed by a thermistor 1 in the core, is compared with the quantity of heat required to meet a determined thermal load during a discharge period, as determined by a synchronous timer motor-driven resistor 3. If the sensed temperature is less than the set temperature a relay 12-14 or a phase-controlled thyristor, fed through transistors 6, 11, supplies current to the heater from a normal supply. A fixed resistor 17 may extend the lower limit of temperature control. The variable resistor may be replaced by a chain of resistors connected sequentially during the discharge period. An additional temperature-sensitive resistor responsive to ambient temperature may be incorporated in the chain 1, 3, 17 which may be arranged in certain circumstances to override signals given by the other resistors. The circuit may be arranged to permit a reduction in the energy consumed during a restricted eight-hour charging period when it is estimated that the thermal load during the subsequent discharge period will be unusually low. The circuit may be applied to a space heating or hot water storage arrangement. The off-peak supply may be other than electrical.

Filed: 1957-12-04
Abstract: 842,134. Metal foil; jointing. SUBMARINE CABLES Ltd. Dec. 4, 1958 [Dec. 4, 1957; March 21, 1958], Nos. 37824/57 and 9198/58. Classes 83 (2) and 83 (4). A method of bonding a synthetic organic thermoplastic to a metallic surface, e.g. copper, aluminium or steel, comprises forming a thin coating of said thermoplastic on said surface and heating the coated surface in a substantially inert atmosphere, e.g. nitrogen. The coating is applied by spraying, dipping, by fusing powdered thermoplastic or by fusing a pre-cast film on the metal surface or by dispersion wherein the dispersion medium, e.g. xylene, toluene, trichlorethylene or carbon tetrachloride, is evaporated at a temperature above the melting- point of the thermoplastic. When a further thermoplastic body is to be bonded to the coated metallic surface, e.g. by heating, such body is applied by extrusion, moulding by compression or injection or casting. In an example a steel article is heated in a container to 95‹ C., and its surface washed with xylene prior to applying a solution of polyethylene in xylene at 95 C. while the container is filled with nitrogen. The temperature is held for 15 minutes, and is then raised for 30 minutes to 145-150‹ C. When the xylene has evaporated the temperature is rapidly raised to 180‹ C., held there for 30 minutes, and then allowed to drop to below 100‹ C. while the coated article is still in the inert atmosphere. Insulators, cables, bushings, glands, condensers, foils and other electrical components may be coated by this method.

Abstract: 1,199,495. Distributing television &c. J. O. CAMPBELL. 17 Aug., 1967 [31 Aug., 1966], No. 37971/67. Heading H4R. In a line television distribution system, each receiver has associated with it a generator of a signal identifying that receiver and means for modulating the identification signal in order to indicate a subscriber's response to a programme. The distribution system described in Specification 1.090,778 is utilized in which a programme selector 17 (Fig. 2) for a television receiver 14 includes a network 29 under the control of the T.V. viewer for passing the selected television programme signals. Also included is a signal generator 30 under the control of the viewer coupled to an isolation network 31 for passing the identification signal back over the line to an analyser and recorder (28), Fig. 1 (not shown). The frequency of the identifying signal provided by the generator identifies the receiver and also the programme selected, or merely the receiver. A switch 32, either electronic or in the form of contacts, is normally closed but may be actuated by the viewer to interrupt the line passing the identification signal. The switch 32, upon being actuated opens for a brief time, e.g. for a second or less, and then automatically closes. A question asked by an announcer may be answered by code, e.g. Morse code, or a double interruption indicates " yes " and a single interruption indicates "no". Alternatively, a modulator 33 (Fig. 3) connects the signal generator 30 and isolation network 31. In operation the viewer speaks into a microphone 34 to modulate the identification signal by the modulator 33. A demodulating network in the analyser and recorder (28) permits the viewer to talk to the announcer.
