Abstract: 692,354. Reinforced concrete. STANTON IRONWORKS CO., Ltd., CORNELIUS, F. B., WEARMOUTH, J. G., WILLIAMSON, F. L., SUDBURY, W: M., LEE, T. S., and WOODHOUSE, D. P. Jan. 16, 1951 [Jan. 23, 1950], No. 1734/50. Class 20(iv) [Also in Group I] The wire reinforcement embodied in centrifugally spun concrete products such as poles or lighting standards is formed in loops, tension being applied to both legs of the loops which lie parallel to and on opposite sides of the spinning axis in a plane containing the axis. Wire loops 12 are held between spigot end plate and base plate assemblies 5, 7, fixed to opposite ends of mould halves a, a<SP>1</SP>, the wire being looped over rollers 3 on a head 2 having a guide member 4 fitting in plate 5 and adapted to be spaced from the plate by means of threaded studs 6 which pass through apertures in the guide member. In assembly, plate 5 with the wires looped over the rollers is loosely bolted to mould half a<SP>1</SP>, the base plate 7 is fixed to the other end and one end of each wire secured by a wedge c to a block 10 spaced by a compression spring 11 from another block 9 fitting on a screw-threaded boss 8 on plate 7. After mould half a is bolted on, the wires are each tensioned by a hydraulic jack, the loose ends of the wires being secured in jaws d and legs f of the jack positioned round the blocks 9, 10; movement of a piston e draws the jaws from the plate, a wedge is inserted, the piston retracted, the jaws being then released. A final tension is obtained by screwing the spigot end plate away from the mould, the compression of spring 11 at the base plate end being measured by a scale 13. After the mould has been filled and spun and the concrete has set, the wires are cut at the base plate end, the plates removed and the product taken from the mould. Recesses formed by bosses 8 are filled in to protect the wire ends. A modified base plate assembly comprises flanged sleeves incorporating a wedge and surrounded by a ring nut which is screwed therealong against the plate after the sleeve has been pulled out by a jack. In another embodiment the spigot plate is attached to a fixed buttress by an internally threaded flange plate, and .a buttress at the other end carries the jacks and a wire gripping plate beyond the base plate. After the wires have been tensioned and the spigot and base plates bolted to the mould the wires are secured by wedges to the base plate beyond which they are severed, the spigot plate being detached from its buttress and the mould transferred to the spinning machine. A further construction provides a mandrel on which the reinforcement, assembly is mounted; one end of the mandrel abuts the spigot plate and the other engages a rod constituting the ram of a hydraulic jack. After initial tensioning a mould is built up round the assembly the tension transferred to the mould and the mandrelextracted after which a fixed tension is applied by adjustment of nuts on the spigot plate studs, or full tensioning may be obtained in a single operation.

Abstract: 1,066,311. Cooling systems for I.C. engines; ventilating vehicles. HUMBER Ltd., and P. M. T. COBLEY. Jan. 15, 1964 [Jan. 16, 1963], No. 2024/63. Headings F4U and F4V. A motor vehicle with a coolant system including a radiator, has a two-part heat exchanger both of which parts 16, 17 cool the engine coolant and heat air which may supply the passenger space, means responsive to the temperature within the space adjusting the coolant flow through part 17. Air from an aperture (15, Fig. 4, not shown) in the vehicle scuttle passes through separate ducts to each of the two separate parts 16, 17. Air from part 16 is supplied to the passenger space or emitted externally by the positioning of a flap valve (21) operated manually from the instrument panel. Air from part 17 is directed either to the passenger space or to demisting outlets by the positioning of a valve (44). Coolant from the engine flows to the radiator 27 and to parts 16, 17, which are connected in parallel, from a valve unit 25, a valve within which prevents passage to the radiator at low coolant temperatures. At a predetermined temperature this valve opens and at a higher predetermined temperature a switch included in the unit 25 switches on the fan 19 to increase air flow to part 16. This switch may be overridden by a manual switch. A manual switch is also provided for fan 20 supplying part 17. Ducts 51 and 52 are connected between the inlet of part 17 and the passenger space and provide cold air around the passengers' faces.

Title: Percussion apparatus
IPC: B25D9/12
Filed: 1966-01-17
Abstract: 1,110,622. Percussive tools. ETABLISSEMENTS MONTABERT. 17 Jan., 1966 [28 Jan., 1965], No. 2051/66. Heading B4C. An hydraulicallyactuated percussive tool, such as a pick or rook drill, comprises a piston 2 movable in a cylinder under the control of a distributing valve 3 slidable in a chamber 18. In operation, pressurized liquid is fed through an inlet passage 6 so as to act on a diaphragm 16 of an accumulator 5 and then flows through a passage 9 to act on the underside of the piston. The piston rises together with the valve against the action of a spring 17, the liquid above the piston being exhausted via passages 10, 7. At the top of the stroke a surface c on the valve abuts against a surface d on the housing 1 thereby closing the exhaust passage 10, 7. At this point the top of the piston is aligned with a passage 8 connected with the inlet passage 6, so that the piston is driven on its working stroke under the action of the energy stored in the accumulator. During the downward stroke, the piston top uncovers a passage 13 thereby allowing the liquid to act on the surface c and so move the valve downwardly to close the passage 8 and open the exhaust passage 10, 7. The piston then repeats the cycle.

Abstract: 542,072. Current and voltage measurements. MEURER, S. Jan. 30, 1939, Nos. 3191 and 3192. Convention dates, Jan. 28, 1938 and Sept. 19, 1938. [Class 37] In apparatus for the piezo-electric measurement of pressure sequences particularly those varying periodically, the piezo-electric circuit of the measuring instrument is, at instants at which its potential is known, charged to this potential in order to compensate for loss of charge due to leakage. Fig. 3 shows an apparatus for the measurement of the pressure in an internal-combustion engine by means of a piezo-electric crystal and a valve voltmeter. A piezo-electric crystal is subjected to the pressure in the cylinder and is connected to the grid of the valve 4 of the voltmeter. On the shaft 14 is a cam 15 which operates a switch 16 in the circuit of a relay 19. On actuation, this relay connects a potential source 22 with the input circuit 3. Alternatively the relay 19 may be omitted, the switch 16 being in series with the source 22. This switch may be actuated directly by the pressure medium by means of a piston, membrane, valve &c. each time the pressure attains a particular value. Alternatively the cathode of the valve may be at positive potential, the switch serving to earth the grid at the engine casing. The quartz crystal must then be so connected that it delivers a negative charge on being relieved of pressure. The biasing potential may be derived from a potentiometer connected across the heating battery for the filament of the valve, and the heating filament of a second amplifier valve may form part of this potentiometer. In cases where a part of the pressure diagram is to be recorded on an enlarged scale, the recording of the remaining part of the diagram may be prevented by applying a potential to the input circuit or by disconnecting the crystal during this period.

Abstract: 877,427. Brushes. OSBORN MANUFACTURING CO. Jan. 29, 1959 [March 13, 1958], No. 3239/59. Class 19. Rotary brush elements consist of an annular hub having a peripheral channel in which outwardly extending bristle material is secured. The periphery of the hub is sinusoidally deformed so the bristle material lies in a series, preferably three, of circumferentially extending, sinusoidal waves. The bristles having outer ends displaced when the hub is deformed are inclined to the central radial plane of the element. These elements are then assembled on a shaft, preferably having resilient discs of a material such as a polychloroprene positioned therebetween. The assembled brush may be subjected to suitable treatment to cause these discs to flow so that the bristle material becomes embedded in the material of such discs. The material of the discs is such that it wears back at a quicker rate than the bristle material.
