Title: Improvements in and relating to lifting surfaces of aircraft
Inventor: HARRISS RICHARD ALAN
IPC: B64C13/00
Filed: 1952-05-09
Abstract: 751,000. Controlling aircraft. ENGLISH ELECTRIC CO., Ltd. May 8, 1953 [May 9, 1952], No. 11866/52. Class 4. A lifting surface of an aircraft, for example a tailplane, having a sweepback of the leading edge and of the trailing edge exceeding 30 degrees, is pivoted about a swept-back first axis which passes between the extreme centroid of pressure positions encountered at different flight conditions whereby the magnitude of the moments about this axis is reduced to a minimum. Fig. 2a shows a plan view of a tailplane and CPf and CPa denote the extreme forward and aft positions of the centroid of pressure. The pivot axis MN passes through the point E of maximum profile thickness and is swept back at an angle a so that it passes between CPf and CPa. As shown in the end elevation in Fig. 2b, the axis MN preferably has a positive dihedral angle # for a high-set tailplane and a negative dihedral angle # for a low-set tailplane; a gap between the fuselage G and the leading edge of the tailplane in the tilted position may thus be avoided, and the gap between the fuselage and the trailing edge may be kept small. The tailplane may have a single span 2, Fig. 2, attached to a trunnion 3 journalled in self-aligning radial- and thrustbearings in the fuselage. A triangular lever 4, attached to the trunnion 3 and also to a point of the root of the tailplane, is articulated to the free end of an actuator 5 which is geared to a common drive unit U which similarly controls the other tailplane.

Title: Improvements in or relating to the production of music
IPC: G10H3/20
Filed: 1927-05-04
Abstract: 296,690. Willans, P. W. May 4, 1927. Instruments with sonorous forks &c., percussive; electrically - vibrated instruments. - In musical instruments of the kind in which the audible vibrations are converted into electric currents which are reconverted into sound, each of the sounding elements is associated with a separate converting device. In the arrangement illustrated, a series of tuning forks 1 and a corresponding series of electromagnets 2 are mounted in proximity. The . forks are sounded by hammers (not shown) operated from a keyboard which also controls switches 5, so that depression of a key starts the fork vibrating and opens the switch, the currents thus induced being led to the input of a radio transmitter 4. The coils 3 may be shunted by condensers 3<a> to suppress undesirable overtones. In a modification, the forks are all mounted in proximity to a single metal plate so as to constitute a series of condensers, which may be connected in parallel to the grid of a transmitting or amplifying valve. In another modification, in which the hammers are dispensed with, the forks are vibrated by separate electromagnets which are momentarily excited on depression of the keys; the exciting currents may be controlled by switches connected to the keys, or they may be supplied inductively by the movements of coils carried by the keys in the field of fixed electromagnets. The forks may be rendered inaudible directly by mounting them in a felt-lined box without a soundboard, or by enclosing them in a vacuum.

Abstract: 998, 881. Automatic control of level. OWENS-ILLINOIS GLASS CO. March 29,1962 [March 29, 1961], No.12015/62. Heading G3R. The thickness of the batch blanket above a fusion layer over the molten glass body in an electrically heated furnace is controlled by measuring the temperature at a point within the furnace, between the batch blanket and the molten glass body and varying the power input to the furnace in response to the variation in temperature at the point. As shown, a thermocouple 17a is manually positioned by a rack and pinion 22a-24a at the mid-point of a fusion layer 16 between a batch blanket 15 and molten body 14 of glass in a furnace 10. The output of the thermocouple is fed to a recording controller 19 which varies a rheostat 21, through a motor 20 to adjust the power input to electrodes 12,13 so as to maintain the desired position of the fusion layer by increase or reduction of the power. In a modification the thermocouple projects downwards through the batch blanket. In alternative arrangements, the thermocouple is controlled to follow the movement of the fusion layer and the rheostat is simultaneously adjusted to tend to restore the fusion layer position.

Abstract: 1,143,226. Electric conductors and insulation. SIMPLEX WIRE & CABLE CO. 18 March, 1966 [18 March, 19651, No. 12020/66. Heading H1A. [Also in Division D1] To ensure that wires that are to be wrapped helically about a core in spaced apart relationship shall maintain their relative disposition during handling of the resultant cable, said wires are helically preformed and the core is formed or provided with a plurality of radially projecting ribs extending along the length of the core, the helically wrapped wires being caused to bite into said ribs. In Fig. 1, the invention is illustrated in the construction of a coaxial cable 29. A central conductor 30 is embedded in dielectric material 32 surrounded by a braided conductor 34. Surrounding the conductor 34 is a layer of dielectric 36 formed with four longitudinally extending and outwardly projecting ribs 38. A layer 39 of preformed helical armour strands is wrapped around the layer 36 such that each strand 40 forms depressions in the ribs 38 where it crosses the ribs. Each strand 40 is also in contact with the dielectric 36 in the spaces between the ribs 38. The central conductor 30 and braided conductor 34 may be of copper, and the layers 32 and 36 of polyolefinic material, for example polyethylene. There may be an external jacket 42 that may be of a polyolefinic material or of rubber. Fig. 5 (not shown) is a schematic representation of a manufacturing arrangement for producing the cable illustrated in Fig. 1. In Fig. 3 (not shown), a thick layer 14 of solid dielectric is extruded about conductor 12, and a relatively thin, exteriorly ribbed layer 16 of semi-conducting material is extruded about the layer 14. Drain wires 18 are then wrapped around the resulting core under sufficient tension to cause depression of ribs 20 and the resulting cable is then pulled through a reducing die to deepen these depressions and also to cause some depression to be made in the surface of layer 16 between ribs 20 by the drain wires 18. The wires 18 are preferably of tin-coated copper and serve to drain off static charges and/or prevent their build up.

Title: Improvements in and relating to the crease-resisting treatment of textile materials
Filed: 1937-05-01
Abstract: 500,184. Anti -crease treatments; dyeing. ROBERTS, A. E., and WATKINS, W. May 1, 1937, No. 12447. [Class 15 (ii)] Cellulose textile materials are steeped in an acid solution of formaldehyde or its equivalent for 2 hrs. or more during which time a reaction is brought about between the materials and the solution, dried and heated ; the materials have an improved resistance to creasing and affinity for dyes. The acid condition of the formaldehyde solution is brought about by the addition of a weak acid, e.g. acetic acid, or an acid salt, e.g. aluminium sulphate. Strong mineral acid may also be added to the formaldehyde solution. The material may be loaded or filled prior to the formaldehyde treatment ; or it may be treated with reinforcement-forming substances capable of reacting with the formaldehyde during the heat treatment, such substances, if resin forming, being in insufficient quantity to produce anti-crease effects of themselves. After drying.and before the heat treatment, the material may be subjected to a mechanical treatment to separate individual fibres according to Specification 465,875. In an example, a fabric was immersed for 51 hrs. in a solution comprising formalin and acetic acid, dried and heated to 130‹ C. for ¢ hr. at 30 lb. above atmosphere. Other examples are similar and comprise further additions to the bath of ammonium chloride, urea with aluminium sulphate, ammonium dihydrogen phosphate and ammonium phosphate. According to a further example, the fabric is steeped for 24 hrs. in a solution comprising formalin, hydrochloric acid and aluminium sulphate, dried and heated.

Title: Improvements in and relating to self-priming centrifugal pumping plant
IPC: F04D9/02
Filed: 1944-06-30
Abstract: 582,355. Centrifugal pumps. SOUTHERN, J. June 30, 1944, No. 12487. [Class 110 (i)] A self-priming centrifugal pump unit comprises a centrifugal pump and a priming pump of the vortex type in parallel therewith, so that the vortex pump operates as a vacuum pump during priming of the centrifugal pump and as a liquid pump after priming. A vortex pump is defined in the Specification as a pump in which a whirling ring or vortex of liquid is created by rotating vanes in a peripherally confined space and a stop member in the path of the rotating liquid causes a proportion thereof to be diverted to a lateral delivery, fresh liquid being drawn in through a lateral inlet. In Fig. 1, the vortex pump is constituted by a series of radial vanes 2, formed on the rear face of the centrifugal pump impeller 1, and inclined to the face as shown in Fig. 2, and extending from the hub to a rim 2a which is in sealing contact with an annular projecting portion 5d of a stationary plate 5. Fluid passes from an inlet port 5b to the vanes 2, and is thrown outwardly by centrifugal force into a volute 5a. The stop member 5e prevents complete rotation of the fluid, which is thereby forced inwardly to an outlet port 5c. The volute may be of decreasing cross-section in the direction of whirl or the section may be constant or a combination of parallel and tapered forms. The suction chamber 4d of the centrifugal pump has a lip 4c to trap liquid and keep the suction eye 1a flooded. A suction chamber 6 for the vortex pump is connected by a pipe 7 to the upper part of chamber 4d and also communicates with the centrifugal pump discharge to the rear of a non-return valve 9 through a bye-pass 7a and a duct 7b. The latter may conveniently be formed in the spider of the non-return valve. The vortex pump discharge chamber 8 is connected by a pipe 10 to the main discharge. On starting up, the residual liquid in the centrifugal pump is raised past the non-return valve 9 and passes through passages 7b, 7a and 7 into the inlet chamber 6 of the vortex pump, and is discharged through pipe 10 into the main discharge above valve 9, and then returns to chamber 6 to be recirculated. During priming, the vortex pump withdraws air from suction chamber 4d through pipe 7. On completion of priming, valve 9 seats itself against the orifice of duct 7b, and thereafter the vortex pump acts as a liquid pump in parallel with the centrifugal pump. The centrifugal and vortex pump impellers may be separate, with a partition between them.
