Title: Starter jaw mechanism
IPC: F02C7/275
Filed: 1954-03-16
Abstract: 751,032. Turning-gear. BENDIX AVIATION CORPORATION. March 16, 1954 [April 16, 1953]., No. 7645/54. Class 7(5) In an engine starter having a gear 7, Fig. 1, driven from a gas turbine, for example, not shown, and connected through an overunning clutch 6 to an ouput shaft 15 adapted to be coupled to an engine member, not shown, wherein a jaw connection 13, 14 is interposed between the clutch 6 and the shaft 15 and is urged into engagement by springs 20, latching means consisting of a sleeve 16 and plate 26, which is normally arranged to effect engagement of the jaw connection 13, 14 permitting disengagement of the latter in response to a given torque in a reverse direction (when the engine starts and overruns the starter) to disconnect the starter from the engine. The starter 1 which is attached to the .engine by a quickly operable coupling 4 is provided with a plate 5 connected through the clutch 6 to the gearing 7, the plate 5 having a block 11 splined thereto; the jaw 13 which is splined to the block 11 normally engages the corresponding jaw member 14 on the shaft 15. The sleeve 16 holds the block 11 on the plate 5, which latter incorporates a pin 17 engaging a slot 18 in the sleeve, the block 11 being urged into engagement with the shaft 15 by the springs 20; the sleeve embodies a number of slots 24, Fig. 3, adapted to be engaged by fingers 25, Fig. 1. on the latch plate 26 secured to the shaft 15 by rivets 27, the slots being so designed that torque may be transmitted in one direction only, a reverse torque moving the fingers out of the slots. After starting the clutch 6 normally prevents the engine from over-speeding the starting turbine but in the event of the clutch malfunctioning the springs 20 enable the starter jaws 13, 14 to ratchet thus placing the load upon the fingers 25 which in the reverse direction of rotation drive the sleeve by friction so that upon a given torque being exceeded the fingers disengage the slots whereupon a spring 23 disconnects the block 11 from the shaft 15. The heads of rivets 27 serve as bearings for the shaft 15 upon the jaws 13, 14 being released. Specification 669,107 is referred to.

Patent GB-828300-A (GB)
Title: Improvements in or relating to the manufacture of electric cables or other insulated electric conductors
Inventor: AUSTIN JAMES ALEXANDER
IPC: H01B7/16
Filed: 1956-03-12
Abstract: 828,300. Cables. PYROTENAX Ltd. March 12, 1956, No. 7709/56. Class 36. In an apparatus for the manufacture of a metal-sheathed, powder-insulated cable in which the powder is fed into the sheath tube behind the head of a ram within the tube and is compressed by relative reciprocations of the tube and ram, the feed of powder to the tube behind the ram head is governed by a valve controlled by a relay operated in accordance with the relative reciprocations of the tube and ram so that feed of powder into the tube is substantially prevented during that period of the reciprocation cycle when the powder is being compressed. As shown applied to the apparatus described in Specifications 669,779, 669,780 and 669,781, powder is fed into the hollow ram F from hoppers M carried by the ram. The flow of powder from the hoppers to the ram is governed by plunger valves N, each driven by a doubleacting piston and cylinder N<SP>1</SP>, N2. The fluid supply to the cylinders N<SP>2</SP>, via the pipes P<SP>8</SP>, P<SP>9</SP>, is controlled by a piston P<SP>1</SP> sliding within a casing P<SP>2</SP> having an inlet port P<SP>3</SP> for the fluid supply and two exhaust ports P<SP>5</SP>. The piston P<SP>1</SP> is operated by a trip arm Q pivoted to the casing P<SP>2</SP> and actuated by a projecting lug Q<SP>1</SP> on the reciprocating ram cylinder E, a spring Q2 being provided to bias the piston to the position shown. During downward travel of the ram cylinder, the lug Q<SP>1</SP> rides past the trip arm Q and the piston P<SP>1</SP> remains in the upward position. The pipe P<SP>8</SP> is thus connected to the fluid supply and the plungers N are positioned by their pistons N<SP>1</SP> to prevent powder feed from the hoppers to the ram. At a point in upstroke of the ram cylinder, the lug Q<SP>1</SP> pivots the trip arm Q to depress the piston P<SP>1</SP> and so connect the pipe P<SP>9</SP> to the fluid supply thus causing withdrawal of the plungers N and allowing feed from the hoppers to the ram. The lug Q<SP>1</SP> then moves past the trip arm Q thus releasing the piston P<SP>1</SP> and so causing forward movement of the plungers N which drives the powder charge into the ram and cuts off further feed from the hoppers. Each cylinder N<SP>2</SP> is closed by a screw-threaded cap N<SP>4</SP> so that the positions of associated plunger N at the end of the backward stroke (and therefore the quantity of powder entering the ram) can be varied by rotating the cap. In another embodiment, Fig. 5 (not shown), the valve controlling the fluid supply to the cylinders N<SP>2</SP> is also the valve controlling the supply of fluid to the ram cylinder.

Title: Improvements in or relating to porous coated cloth
IPC: D06M11/83
Filed: 1955-03-16
Abstract: 774,326. Porous, heat-reflective coated fabrics; ironing. GLATT, H. March 16, 1955, No. 7723/55. Drawings to Specification. Classes 138 (2) and 140. A ventilated cloth of improved surface, smoothness and heat-reflectivity comprises a closely woven textile and an organic resin coating applied substantially uniformly on one surface only by knife coating in amount of 0.3-1.4 oz. dry solid per square yard and depositep mainly in the interstices of the textile but insufficiently deposited to completely fill the interstices, so that small vent openings are formed in the resin coating in the interstices. The textile may be rayon, cotton, partially acetylated cotton, nylon, polyacrylonitrile, or polyester. 4-12 per cent of a reflective pigment, e.g. aluminium, is included in the coating composition. In making porous ironing pad covers the resin must withstand at least 500‹ F., and cotton drill is coated with an organic solvent solution of polyvinyl butyral with or without phenol-, urea- or melamineformaldehyde, or glyoxal resin for cross linking. Suitable plasticizers, fillers and organic solvents are exemplified. After drying the coating by heating rolls a light coating of an aqueous emulsion of a dimethyl silicone may be applied by flannel wetted with the emulsion, but the limitation as regards weight and incomplete filling of the interstices is still observed. In making porous interliners for garments rayon satin is coated with the above resins or with polyvinyl chloride, polyvinyl acetate, polyvinylidene chloride, or alkyds.

Title: Improvements in explosive mines and the like
IPC: F42C14/04
Filed: 1929-03-09
Abstract: 332,265. Harrison, J. K.. M. March 9, 1929. Transformers. - The low voltage supplied by a sea battery is converted to a high voltage for firing a sparkgap detonator in a submarine mine. Various step - up transformer devices are described for this purpose. In one form, Fig. V, a rectangular transformer core 38 has a gap 39 in one side and a primary coil 34 and a secondary coil 36 on the other side; a spring armature 41 is mounted over the gap, and when attracted by the magnetic field breaks the primary circuit in conjunction with which a suitable condenser 42 is provided, thereby causing a high voltage in the secondary circuit. In a modification, two primary coils in parallel and two secondary coils in series are fitted one on each side of a rectangular core, and a spring armature switch device is arranged opposite a V- shaped notch in the core. In another form, the switch device is operated by a separate magnetic core 48, Fig. VII, energized by the primary current; the armature 55 is pivoted at 50 and balanced by weights 58; a contact spring 41-on the armature bears against a contact screw 40; and the armature is further controlled by another spring 53. In still another form, Fig. IX, the transformer core 38 has a gap 38a; two primary coils 34 are fitted on opposite limbs of the core, and the secondary 36 is built up of four sections. The switch device 37 comprises an armature 55, Fig. VIII, operated by a separate core 48. The. armature is held on one side by an electromagnet or a permanent magnet 68 until the primary current has risen to a certain value, when the field of the core 48 throws the armature over and breaks the circuit between contact blades 40, 41. In another modification, Fig. IX, the transformer has multiple section 36<a> built up in a casing held together by bolts 125. The switch device comprises a fixed screw 130, Fig. XIII, and a blade 133 on a rotatable armature of a separate core 38. The primary circuit is shorted by a bridge-piece 110, Fig. XI, on a stem 111 normally locked by a soluble plug 118. When the mine is submerged this plug dissolves away, and an hydrostat 12<x> depresses the bridgepiece 110 away from contacts 31a connected to the terminals of the primary circuit. The detonating device comprises two detonators 173 in a tubular casing 160 attached directly to the bottom of the transformer casing.

Title: Improvements in or relating to electrostatic printing arrangements
IPC: H01J31/06
Filed: 1961-03-03
Abstract: 978, 564. Electrostatic recording. A. B. DICK CO. March 3,1961 [March 14, 1960], No. 7892/61. Heading G5R. [Also in Division H4] The invention relates to an electrostatic image-recording arrangement utilizing a cathoderay tube 10 having a face plate 32 through which extends an array of wires 34 which engages a moving strip of electrostatic recording material 36 passing over a conductor 38. The electron beam is deflected along the array by a scanning signal source 28 whilst being modulated by an image signal 15. In accordance with the invention, a signal 45 of high frequency (100 mc/s is suggested) having an amplitude sufficient to cause charge deposition is applied to modulate the potential of conductor 32 whereby the recording is made in response to the differential potential due to signal 45 and the potential induced on wires 34 by the electron beam, which is operated at a low potential such that the induced potential is insufficient by itself to cause charge deposition.

Title: Improvements in time-measuring escapement mechanism for clocks and watches or other purposes
IPC: G04B15/12
Filed: 1938-03-16
Abstract: 505,059. Clocks and watches. KING, N. R. March 16, 1938, Nos. 8101 and 14600. [Class 139] A lever escapement is so constructed that in one direction of motion of the impulse roller or pin 7 the pallets are unlocked and an impulse given to the balance, whereas there is no impulse in the other direction. One of the horns of the fork is resilient, Fig. 4 (not shown), or resiliently mounted, Fig. 1, in one direction so that in returning, after the unlocking movement, the impulse roller or pin wipes freely past this horn. In another construction, Fig. 3, the fork 9, 10 is solid and the roller 7 carries a spring blade 18 which, clockwise, wipes past horn 10. The horn 10, Fig. 1, is pivoted at 13 to the lever 4 and biassed clockwise to a limiting position by a spring 16. As the roller 7 on the balance staff 8 oscillates clockwise it merely wipes past the horn 10, leaving the escape wheel 1 in the looked position shown. On returning counterclockwise the roller 7 meets horn 10 and rocks the lever 4 so that pallet 2 unlocks the wheel 1. The latterthen, through the impulse face of pallet 2, causes horn 9 to give an impulse to the roller 7. The latter. passes horn 10 and a scape tooth directly meets the impulse face of pallet 3 (which never locks wheel 1) and returns the lever 4 to the locking position shown as the roller reaches its end position 7c. The coacting surfaces of horn 9 and roller 7 are so shaped that a rblling action takes place between them.

Title: Process for the production of sulphates
IPC: C01D5/04
Filed: 1930-03-13
Abstract: Ammonium, sodium, zinc, copper, and other sulphates are obtained by introducing a gaseous mixture containing sulphur dioxide and oxygen in an extremely finely subdivided state into an aqueous medium in the presence or with the addition of the base the sulphate of which is desired.  The extremely fine subdivision of the gaseous mixture is effected by forcing it through microporous plates, or porous rotating tubes, or by the use of stirring members rotating at speeds of 3000-4000 revs. per min. The reaction medium is preferably kept neutral say at a pH value of 4-5 and elevated temperatures may be used.  Sulphates formed may be recovered by cooling the saturated solutions obtained, the mother liquor being returned to the process; or reaction may continue beyond the limit of saturation and the salt deposited be removed continuously or intermittently.  Reaction may be assisted by the presence of small amounts of copper, manganese, or iron sulphate or copper chloride, sodium chloride being added if necessary to keep the added salt in solution.  The air or oxygen only need be introduced in a finely subdivided state, the sulphur dioxide being then present in, or added to the solution; for instance it may be introduced as gas, or as a solid or dissolved salt.  Ammonium sulphite may thus be oxidized to sulphate.  Gases containing less than 5 per cent of sulphur dioxide, obtained for instance by roasting pyrites, zinc blende, or gas purifying agents or in desulphurizing slags may be directly used in the process and their rate of feed is preferably so adjusted that the exit gases still contain a trace of sulphur dioxide.  Feeding may be effected through a lower supporting macroporous layer surmounted by an upper microporous layer.
