Title: Improvements in liquid flow control systems
IPC: G05D11/00
Filed: 1951-06-11
Abstract: 727,316. Fluid-pressure servomotors; fluidactuated valves. DE HAVILLAND AIRCRAFT CO., Ltd., and GARDINER, G. C. I. June 11, 1952 [June 11, 1951], No. 13828/51. Class 135. A liquid flow control system suitable for controlling flow of fuel simultaneously from two tanks of differing capacity in an aircraft, wherein the rates of flow are required to be proportional to the respective capacities of the tanks comprises a pressure equalizing valve 3 movable by a piston 4 under the control of the pressures downstream of the valve in pipes 1, 2 leading from the two tanks, and a flow proportioning valve 8 controlling ports in the pipes 1, 2 and actuated by a piston 9 subject to the pressure in one of the pipes 1, 2, as shown the pipe 1, and to the pressure in a common pipe 11 into which the pipes 1, 2 merge. As the valve 3 maintains equal pressures in the pipes 1, 2 upstream of the valve 8, the required relation between the rates of flow is obtained by making the ports of the valve 8 of appropriate widths and shaping one of them to compensate for variations in the orifice coefficients due to the two ports not being geometrically similar for all positions of the valve. As shown, the pressure equalizing valve is subject to the action of a control valve 21 actuated by a flexible diaphragm 22 having connections 23, 24 with the pipes 1, 2, but in a modification the two sides of the piston 4 of the equalizing valve are connected directly with the pipes 1, 2. A motive fluid supply connection 7 to the control valve 21 is taken from a by-pass conduit 14 connecting with a point upstream of the valve 3 in the pipe 1 having the lower flow, this point providing the highest pressure in the system, whilst exhaust outlets 29 from the valve 21 lead to the pipe 1 downstream of the proportioning valve. The bypass conduit 14, together with a by-pass 15 from the other pipe 2, lead to a by-pass valve from which a conduit 18 passes to the pipe 11, and the two by-pass conduits are normally closed by pressure in the pipe 11 acting through a pipe 18a on a piston 17 in opposition to the pressure in a pipe 20 connected to the fuel vent system. In the event of malfunctioning of the system resulting in a lowering of the pressure in the pipe 11, a spring 19 opens the by-pass valve. Downstream of the junction with the conduit 18 the pipe 11 leads to an enginedriven fuel pump and also has a branch to a third tank with a float-controlled inlet valve and serving as a short term accumulator. Instead of the proportioning valve being actuated directly by the pressures in the pipes 1, 11, it may be servo-operated as is the pressure equalizing valve. Also, the actuating pistons may be replaced by flexible diaphragms.

Title: Thrust indicator system
IPC: G01L5/13
Filed: 1950-06-05
Abstract: 674,552. Electric indicating systems. BENDIX AVIATION CORPORATION. June 5, 1950. [July 5, 1949] No. 14016/50. Class 40 (i). In apparatus for measuring the thrust of a jet engine on an aircraft fuselage during acceleration, the engine 10 (Fig. 1) is mounted on rigid steel columns 14, 16, 18, 20, and a dummy load 26 is mounted on similar columns 28, 30, 32, 34 on an axis parallel to that of the engine. Strain gauges 36, 38, 40, 42 attached to the engine supports are connected in opposite arms of a Wheatstone bridge (Fig. 2), and the network is completed by strain gauges 44, 46, 48, 50 similarly attached to the dummy load supports. When the aircraft is at rest or moving without acceleration, the thrust of the engine deflects its supports while those of the dummy load are undeflected, and the bridge unbalance indicated on galvanometer 64 is a measure of the thrust. When the aircraft is accelerating, the engine supports are deflected by the net thrust, plus the force due to the acceleration of the engine. The dummy load supports are similarly deflected by the force due to its acceleration, so that the unbalance of the bridge due to the engine support deflection is compensated for the error due to the acceleration force if the respective strain gauge sensitivities are inversely proportioned to the respective masses of the engine and the dummy load. The galvanometer then measures the net thrust of the engine.

Abstract: 351,175. Coated fabrics. VARA Y DE RUEDA, A., 22, Calle San Pedro, Madrid. May 7, 1930, No. 14061. Convention date, May 14, 1929. [Class 140.] In the manufacture of gramophone record blanks having an impregnated base of a fibrous substance such as cardboard or felt, with a lac coating, a mixture of resin and asphalt is used as the impregnating material. The gum-lac coating preferably contains very finely powdered emery, with or without a colouring pigment in addition. A preferred process is as Follows: Porous cardboard of very pure pulp is cut into squares, which are dried and impregnated in a mixture of colophony and asphalt, melted together. Before they are quite cold, the impregnated sheets are rolled or pressed, and are then soaked repeatedly in a solution of gum-lac dissolved in alcohol and having mixed therewith fine emery and lampblack, the mixture having been strained before use. The proportions of the ingredients mentioned are specified. After the successive soakings, the cardboard sheets are hung up by each corner in turn, to ensure even distribution. The sheets thus coated are dried slowly, with graded increases of temperature during successive stages, and are rolled whilst still warm, before sound-grooves are impressed thereon by heat and pressure ir. the usual way. The Specification as open to inspection under Sect. 91 (3) (a) states also (1) that the impregnation of the cardboard &c. with resin may be effected by " injection by compressed air or by vacuum," and (2) that instead of applying the lac coating in solution, the sheets may be covered with a suitable mordant and then dipped in a mixture of finely powdered gum lac and emery. This subject-matter does not appear in the Specification as accepted.

Title: Electrostatic pinning of film to quenching surface
IPC: B29C48/08
Filed: 1970-03-24
Abstract: 1310604 Air-knife assisted electrostatic pinning E I DU PONT DE NEMOURS & CO 24 March 1970 [24 March 1969] 14131/70 Heading B6B In a process for quenching a thermoplastic film at high speeds the molten film is extruded on to a rotating, quenching drum and is urged against the surface of the drum simultaneously by (a) an electrostatic force of from 5-15 Kv, preferably from 10-15 Kv, at the two edges of the film, and (b) an air current having a uniform pressure of from 0À5 to 3À0 inches of water across the full width of the film. The process, which is applicable to many thermoplastic materials, is particularly suitable for use with polyesters. Its use with polyethylene terephthalate is exemplified when speeds of extrusion of between 60 and 145 feet/minute are used with an air pressure of between 0À5 and 2À0 inches of water. The process permits the production of clear, uniform films at higher speeds than is possible using only full width electrostatic pinning.

Filed: 1974-03-29
Abstract: 1457588 Homopolar machines SIEMENS AG 29 March 1974 [29 March 1973 6 July 1973] 14136/74 Heading H2A In a homopolar machine with two coaxial relatively rotatable members defining an annular air-gap into which a conducting liquid is introduced under pressure, a freely floating ring is arranged in the gap, its circumference being pierced through by a plurality of apertures. The liquid metal e.g. mercury or sodium alloyed with potassium, gallium or indium is introduced from pressure vessels (not shown) via ducts 10 into an annular channel 9 in the stationary member 7. The apertures 16 allow two films 17, 18 to form and friction forces maintain the ring 15 in the centre of the gap. Wings 19 extending at the end of the ring 15 throw the escaping liquid metal into collection channels (12, Fig. 1, not shown), and the axial forces set up thereby keep the ring 15 in position. In a modification (Fig. 3, not shown), a ring (21) is fixed over the exit port of the duct 10 whilst not restricting liquid flow. The ring 15 has an extension projecting towards the ring (21), the apertures 16 being formed through the extension. Thus any movement towards the ring (21) restricts flow through the apertures setting up a restoring force. A plurality of floating rings may be used either side-by-side or arranged radially inside each other.

Abstract: 1,008,863. Anchor-bolts; screw-sockets. SOC. ANON. DES FORGES & BOULONNERIES HERMANT-HICGUET ET D'ARS-SUR-MOSELLE. April 12, 1962 [April 13, 1961; July 25, 1961; March 28, 1962], No. 14252/62. Heading F2H. Each shell 1, 1<SP>1</SP>, Fig. 6, of the expansible anchorsleeve, e.g. of a mine roof bolt, has at least one ramp 5, 5<SP>1</SP> for co-operation with a sloping face of a wedge, formed at the end of the shank 8 or on a nut threaded on the shank end, and also has a cavity 13, 13<SP>1</SP> separated from the ramp 5, 5<SP>1</SP> by a shoulder 14, 14<SP>1</SP> on which the shell 1, 1<SP>1</SP> rocks on the wedge face in the position of final expansion (when the bolt shank 8 is drawn out of the bolt hole to its extreme location) so that the shell is spread in the form of a V as shown in Fig. 6. There may be further steeper shell-ramps 7, 7<SP>1</SP> so that a lug 11, at the top of each of the two parallel sides of the flat wedge between the sloping faces, bears on both the ramps 7, 7<SP>1</SP> to give the wide spread at the tops of the shells. In the form shown in Fig. 7, there is a single convex ramp 24 in each shell for co-operation with a concave face, Figs. 8, 9 (not shown), and the lugs 32, 32<SP>1</SP> of the wedge 31. The shells may be interconnected by spring leaves 3, Fig. 6, and these may be crossed, Fig. 1 (not shown), or side-by-side as are the leaves 23, 23<SP>1</SP> in Fig. 7. The leaves tend to hold the shells apart for the pre-anchoring of the bolt which may be facilitated by mounting a rubber ring on the sleeve. In place of the leaves a stop-plate may be fitted on the rod to prevent axial movement of the sleeve shells on insertion in the bore hole. The shells may be kept in position by an elastic band and have lugs to prevent their relative axial movement. In another form, Fig. 10, with convex ramps 37, 38, and corresponding concave faces on the wedge 47, the parallel faces of the wedge are rebated towards the free end but, at the end, a lug 55 extends from each face thus inset and holds, on that face, one of a pair of resilient pads 53 of rubber or spongy synthetic material when the bolt is in the condition shown, ready for insertion. Inturned lips 43, 44 at the end of the shells 35, 36, each with a slot 45, 46 at its middle to allow the rebated wedge-end to pass through, retain the pads 53 when the wedge 47 and shank 48 are displaced upwardly, Fig. 11 (not shown), compressing the pads, when the sleeve is impeded by a narrowing of the bore and the shells are tightened together. The sleeve is returned to the position shown by the resilience of the pads when the narrowing is passed. The shells are held together, at least temporarily, by a rubber band. Stop-ribs 49, 50 on the shank 48 move up into slots 41, 42 in the ramps 37, 38, when the shank moves up in the sleeve, to abut on shoulders 39, 40.

The carrier member 4 is rigidly secured at its lower end to the metal top cap 5 of a support insulator 6 and is either bolted or welded at its top end to the midpoint of the bus-bar support tube 2. An end support tube 3 may be provided with an extension arm 3A which can be weighted to provide a full or partial counterbalance. The height at which the support tube is carried above the insulator can be made at least equal to the minimum phase to phase voltage clearance corresponding to the rated voltage of the system. The insulators 6 may form parts of the insulation of disconnect switch gear.

[Also in Division E1] A method of moving a pile through the surrounding earth in which it is disposed comprises mounting on the pile an oscillating synchronous linear electrical device, supplied with high frequency A.C.and if required D.C.,from an electric generator or generators, so as to impart vibrations to the pile, sensing the vibration conditions of the pile and the surrounding earth, feeding the sensed earth conditions to the generator or generators to adjust the output thereof to the said electrical device, whereby the frequency and amplitude of the vibrations imported by the electrical device to the pile are adjusted to the optimum conditions of operation for moving the pile. Any pick-up service of an electronic, ultrasonic or electromagnetic nature may be employed, preferably rigidly attached to the pile, the signals emanating from the pick-up device being fed back to the generator which supplies the a.c. oscillations to the windings of the electrical device so that the output of the generator will be responsive to the conditions cf the vibrated pile and surrounding earth and these may be compared with a standard vibration e.g. by means of a wheatstone bridge, and if they differ from the standard then the generator control will be actuated in a conventional manner to cause the generator frequency output and voltage to be adjusted so as to vibrate the electromagnetic part of the vibrating device at the optimum pile-moving frequency.
