Title: Improvements in rotary liquid electric rectifiers
IPC: H02M1/30
Filed: 1935-12-09
Abstract: 451,079. Mercury switches. SIEMENSSCHUCKERTWERKE AKT. - GES., Siemensstadt, Berlin. Dec. 9, 1935, Nos. 34077 and 34078. Convention dates, Dec. 7, 1934 and Feb. 11, 1935. [Class 38 (v)] A rotary liquid-jet rectifier has the surfaces of contact of the fixed contacts arranged to extend approximately in the same direction as the direction of outlet of the liquid jet so that the jet flows in sweeping contact over these contact surfaces. Thus the stationary contacts are arranged in a manner similar to the guide blades of turbines. As shown in Figs. 1 and 2 the mercury is raised within the rotating body 4 either by an internal passage formed similarly to a worm thread or through bent tubes 34 having their lower leading edges arranged to scoop up the mercury during rotation so that in either case the mercury is ejected through downwardly-inclined jet openings 5, the jets playing on an annular series of spaced stationary contacts. These contacts are mounted within an insulating ring 11, 12 and are formed with hollow internal passages which are each engaged at an angle to the direction of rotation of the jet and approximately in the direction of outlet thereof in the known manner of guide blades in turbines. Thus the mercury after being ejected from the jet sweeps smoothly through the contacts before falling on to a guide plate 27 of insulating material and returning to the main body of mercury in the container 1. To assist the contacting action the jets and contacts may be provided with partitions 7, 8 to subdivide the jet and wings or guides 9 may be provided on the outer sides of the fixed guide-blade contacts. The contacts may be separated by inwardly-projecting insulating projections 28 cr can be air spaced from separating insulating partitions. Various modified forms are described as for example one in which downwardly directed jets are employed (Figs. 5 and 6, not shown), or in which an annular chamber is formed within the rotating jet member to ensure an ample supply of mercury to the jets. The D.C. is collected by a brush 39 on a collar secured on the driving shaft 20 above the bearing 21. To vary the timing the lid 2 carrying the fixed contact ring may be adjusted angularly on the container 1. In some further modifications of the invention in order to reduce the electrical contact resistance of the jets supplementary sliding or rolling metallic contacts may be incorporated in the structure. The relatively fixed contacts may be arranged to overlap at their leading and trailing ends to form a continuous contact path for the sliding or rolling contacts. The contacts are preferably made from or coated with a material free from anodic corrosion such as platinum, nickel, and nickel-iron alloys.

Abstract: 1,116,881. Thawing frozen foods. NATIONAL RESEARCH DEVELOPMENT CORPORATION. 18 Aug., 1965 [20 Aug., 1964], No. 34132/64. Heading A2D. Frozen blocks of foodstuffs are thawed by conveying them along a predetermined path and passing a current of warm moist air over the blocks in a direction parallel to the path taken by the blocks. Frozen blocks or fish 13 are fed on to a conveyer 12a and are transported within a chamber 11 to the end of this conveyer 12a from which they drop by gravity on to a second conveyer 12b travelling in the opposite direction and are finally discharged after dropping through self-closing slats 36 into a hopper 35 having a hinged door 37. Air is circulated round the apparatus, to pass over the blocks 13 in the same direction in which they are being conveyed, by a fan 14, the air being heated and humified by passing through a hot water spray in a duct 15.

Filed: 1960-10-06
Abstract: 926,317. Vertical take-off and landing aircraft. ROLLS-ROYCE Ltd. Sept. 29, 1961 [Oct. 6, 1960], No. 34230/60. Class 4. A vertical take-off and landing aircraft has a housing containing a vertical lift engine and provided with an upwardly movable air inlet grid of fixed guide vanes, whereby the distance between the grid and the engine air intake can be increased when the engine is to become operative. The Figure is a part cross-section of a fuselage taken in a plane transverse to the fuselage. When direct lift is required, a jack 65 is operated to fold back a door in two hinged parts 57, 58, as shown in broken lines, and jack 55 is extended to raise grid 49 about pivot 53, to allow any swirl in the air passing through the grid to die away before the air reaches the engine intake 42. According to the Provisional Specification, the vanes of the grid may be pivotable about axes parallel to the fore-and-aft axis of the aircraft, so that when the grid is lowered the vanes form an unapertured surface which acts as a closure member for the housing air intake aperture, and a swinging door is operable by a jack to open or close an engine exhaust gas aperture in the lower face of the housing. Specification 896,348 is referred to.

Filed: 1961-09-25
Abstract: 949,336. Making locking nuts. UNITEDCARR FASTENER CORPORATION. Sept. 25, 1961 [Sept. 26, 1960], No. 34298/61. Heading B3A. [Also in Division F2] A lock-nut has a barrel 16, e.g. of 302 stainless steel which is not heat treatable (or of aluminium or brass to which heat would be detrimental), and on the barrel a ring 14 of stainless steel is secured as a press fit and is also deformed to elliptical shape and hardened to give it resilience. In the case of the aluminium or brass barrel, the ring 14 is preformed to elliptical shape and hardened before fitting to the barrel, otherwise a cylindrical ring is fitted and deformed and then heat-treated. The pressure of the ring 14 deforms the barrel 16 to an elliptical shape at its free end but where it bears an apertured disc-flange 12 or elongated flange, Figs. 10, 12 (not shown), the end of the barrel is substantially undeformed.

Title: Bag making machine and method
Inventor: BATEMAN LAWRENCE GILES
IPC: B31B23/00
Filed: 1964-08-21
Abstract: 1,073,572. Making bags. DELAMERE & WILLIAMS CO. Ltd. Aug. 21, 1964, No. 34338/64. Heading B5D. A bag-making machine having sealing apparatus produces longitudinally spaced seals in a continuously moving strip of bag-forming material, the sealing apparatus comprising a pair of opposed conveyer means each of which has longitudinally spaced sealing elements arranged to co-operate with corresponding sealing elements on the other conveyer means and means for effecting an increase and a decrease in the pitch of the sealing elements. Heat sealable material is fed from a roll 12 under a shaping member 30 where it is formed into a U-shaped strip, between rollers, 36, 38, and then between opposed continuously travelling conveyer chains 44, 46, having electrically heated sealing bars, 40, 42, which grip and withdraw the material from the roll and also seal together the side walls of the strip along spaced transverse zones. The chains 44, 46 are separated from each other under the action of a spring when the machine is stopped to permit threading the leading edge of the strip, while on starting the machine an air cylinder and piston rod overcome the spring and move the two conveyers along transverse rods towards each other. The conveyer chains comprise expansion links between the sealing bars and are expanded and contracted between adjustable stops by the action of a compressed-air device and springs which vary the distance between shafts 62, 66 and 70, 74 connected to sprockets 60, 64, 68, 72 driving the conveyer chains. In operation printed areas on the strip are fed past a photo-electric cell 208 controlled by a pair of contacts which are closed once during each individual sealing operation. With the chains in the contracted position the sealing bars are a little closer to each other than the spacing between printed areas on the strip, so that eventually the cell 208 detects the trailing edge of a printed area on the strip and then operates the air device to stretch the conveyers, the air device being kept in operation for a fixed time by a delay. When the conveyers are stretched the sealing bars are spaced a little further apart than printed areas on the strip which thus " advance " to become clear of the photoelectric cell by the end of the fixed time at which the conveyers are contracted. In this way registration of the sealed portions with the spaces between the printed areas is maintained and production tolerances in the spacing between the printing are accommodated.

Title: Electronic system for displaying artificially produced environment patterns
IPC: G09B9/05
Filed: 1972-07-21
Abstract: 1389861 Driving simulators AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY 21 July 1972 [22 July 1971 (2) 22 Nov 1971] 34348/72 Heading B7H [Also in Division H4] Patterns (e.g. environmented patterns) having a predetermined colour distribution are produced on the screen of a colour display cathoderay tube (e.g. a TV Monitor) under the control of analogue electrical signals representative of mathematical functions of the geometrical shapes which form such patterns. The invention is described in connection with a simulator which presents a display of the changing environmental pattern presented to the driver of a motor vehicle but is applicable also to aeroplanes, trains and ships. Fig. 1, shows one form of pattern which comprises a (blue) sky part 1, a (grey) road part 2, (green) areas 3, and (white) guard rails 4 and supporting posts 5, the pattern being produced on the (CRT) screen S, see Fig. 2 (which shows a plan view of the pattern) and Fig. 3 (which shows the pattern in elevation), in relation to the viewing position P on the vehicle. From the constructions shown, equations are derived in terms of the X and Y co-ordinates of the various areas and elements of the pattern as modified by the variables D (lateral deviation) and the velocity V (a time function of the distance b of the past 5 nearest to screen S) and by means of circuitry supplied with analogue voltages corresponding to the fixed variable parameters and with ramp voltages derived from the X and Y synchronizing signals of the display system gating voltages are derived which gate appropriate colour producing signals to a colour signal modulator controlling the display (see Figs. 5, 6, 7 and 8). The display may be controllably varied when the "road" is curved instead of straight (Figs. 4A and 4B, neither shown) and to compensate for changes in attitude of the vehicle such as roll, pitch and yaw (Figs. 9A, 9B and 9C respectively, none shown). Other patterns which may be produced comprise "tunnels" (Figs. 11A, 11B and 11C, none shown) "cut-through" road pattern (Figs. 16A and 16B neither shown) and entrance and exit "ramps" (Figs. 18A, 18B, 19A and 19B, none shown). Fig. 20, shows a further arrangement in which the same technique is employed to produce a display simulating the view of the rearward environmental pattern which would be seen in a "mirror" 59<SP>1</SP> and Fig. 21 shows the arrangement of the whole simulator system including a steering wheel 67 accelerator pedal 68 and brake pedal 69 under the control of which variable analogue signals representative of the velocity V and the lateral deriation D of the vehicle are derived and supplied to the simulating circuit 76. The arrangement for deriving the signals representative of V and of D is described with reference to Fig. 22 (not shown).

Abstract: 934,085. Oil-break switches. ALLMANNA SVENSKA ELEKTRISKA A.B. Sept. 28, 1961 [Nov. 8, 1960], No. 34822/61. Class 38 (5). An oil circuit-breaker arc extinguishing chamber includes a nozzle-shaped fixed contact which, at least in the contact open condition allows oil to pass from a compartment of the extinguishing chamber and has a pocket of gas trapped in the compartment and a differential piston through which the moving contact passes. As shown in Fig. 1, the compartment 7, 8 is filled with oil up to a lever controlled by an opening 9 and on separation of contacts 3, 5 the compression of the gas above the oil results in a flow of oil and arc gases through the nozzle control 3 at current zero. The pressure also forces the piston 4 downward to pump pure oil from the space 10 through a slot 11 which is uncovered as the moving contact is withdrawn along a passage 6 in the piston 4. In Fig. 2 (not shown) an insulating wall is provided between the compartment 7, 8 and the piston to ensure axial oil flow and in Fig. 3 this wall 13 is associated with over pressure valves 16 in the differential piston compartment. In Fig. 4 (not shown) there are two walls between the two parts of the chamber which also has outlet openings between the walls.

Abstract: 650,750. Electric control systems. FEUERSTEIN, M. J. S. Dec. 31, 1947, No. 34950. Convention date, Dec. 12, 1938. [Class 40 (i)] In an arrangement for the proportionate introduction of an auxiliary fluid into a main fluid stream, a flow meter responsive to the main fluid velocity actuates through a followup switch a reversible electric motor which controls the gear ratio between a pump and its constant speed driving source, whereby the pump varies the amount of auxiliary fluid introduced in accordance with the velocity of the main stream. The indicating arm 7 of a Venturi meter 6 responsive to flow through the main pipe 1 carries the contact 8 of a followup switch 8, 9, 10 controlling an electric motor 13, rotation of which drives the follow-up disc 11 through worm gearing 12, and through a spindle 20 and travelling nut 21 laterally shifts a belt 24 to vary in correspondence with the main flow velocity, the gear ratio between the constant speed driving pulley 25 and the pulley 26 which drives the pump 30 introducing the auxiliary fluid from tank 31 into the main pipe 1. Other types of variable speed gearing may be used, e.g. Flender or Reeves gears, or, as in Fig. 2 (not shown), a driving friction wheel may be moved radially relative to the wheel it drives by the gear changing motor. Any type of pump may be used.
