Title: Improvements in or relating to devices for supplying liquid under air pressure
Inventor: FRASER JOHN
IPC: F16N37/02
Filed: 1951-09-24
Abstract: 708,301. Forcing liquids by gaseous pressure. AVERY-HARDOLL, Ltd. Aug. 15, 1952 [Sept. 24, 1951], No. 22321/51. Class 102 (2). In apparatus for forcing liquids by air pressure, the container 10 contains a float 43 that slides on a rod 42 fitted with stops 44, 45. A lever 47 is pivoted at 48 and carries a spring- loaded pawl 53 cooperating with a lever 55 connected to a rod 57 so as to provide a snapaction of the valve 65 at the extreme limits of movement of the float 43. The valve 65 controls an atmospheric port 68 and a port 69 supplied with air under pressure. The supply of air under pressure to the container 10 forces the liquid through openings 38 in a disc 36 attached to a guide sleeve 35. The disc is maintained a short distance from the base by feet 39 and its edges are close to the housing 41 to leave an insufficient cross sectional area for the flow of liquid. The liquid thus raises the disc to uncover the ports 29. The disc in its raised position prevents the rod 42 from descending sufficiently to actuate the valve 65 to connect the container 10 to atmosphere.

Title: Shoe expanding devices for internal shoe drum brakes adjustable speed projector
IPC: F16D65/14
Filed: 1972-05-12
Abstract: 1424536 Internal shoe drum brakes AUTOMOTIVE PRODUCTS Ltd 2 May 1973 [12 May 1972] 22374/72 Heading F2E A shoe expanding device for an internal shoe drum brake comprises a piston or pistons 11, 12 of a single or double acting wheel cylinder urged apart to apply a shoe or shoes of the brake by liquid pressure or by a wedge member 13 movable between a fixed abutment and the piston or between adjacent ends of the pistons 11, 12 and having rollers 26 located by a cage 29 mounted on the wedge member 13, stops being provided on the wedge member 13 and cage 29 which when engaged one with the other determine the relative positions of the wedge member 13 and cage 29 such that rollers 26 engage the thin end 23 of the wedge member. A spring 34 acts on one of the stops which spring yields to allow the wedge member 13 to be retracted in advance of the cage 29 if the stops engage before the wedge member is fully retracted. The cage 29 is U-shaped having two limbs 28 provided with a rectangular opening 31 in which are located washers 32, 33, slidable on the wedge member, the washer 32 co-operating with a shoulder 36 on the wedge member to constitute the stops. Wedge member 13 is moved by a stack of Belleville washers 17 to apply the shoes upon release of hydraulic pressure in a chamber 22 whereupon the rollers 26 roll in slots 27 between the wedge and piston surfaces 24 and shoulder 36 moves away from stop washer 32. If the brake shoes are partially applied by liquid pressure acting in wheel cylinder 10 and washers 17 are brought into action, wedge member 13, cage 29 and rollers 26 move together until rollers 26 contact piston surfaces 24 and only during further movement will the wedge member 13 move in advance of cage 29 and rollers 26. If liquid pressure in cylinder 10 is first released and pressure then restored to chamber 22 rollers 26 return to their idle position. Shoulder 36 then contacts washer 32, spring 36 yields allowing rollers 26 to roll until they come opposite to transverse grooves (37), Fig. 3 (not shown), at the thin edge of wedge member 13. The grooves ensure that the brake shoes are spaced from the drum when the rollers are engaged therein so that there is no load on the rollers. With the load released cage 29 returns to its normal position under the bias of a  spring 35.

Title: Improvements relating to stop motions for spinning, twisting and analogous machines
IPC: D01H13/18
Filed: 1947-08-14
Abstract: 631,503. Stop-motions for textile spinning &c. machines. PRINCE-SMITH & STELLS, Ltd., and FEATHER, E. E. Aug. 14, 1947, No. 22611. [Class 120 (ii)] In an electrically-controlled stop-motion for a textile spinning or similar machine arranged to arrest delivery of the affected thread upon thread breakage, a detector located above a spindle unit closes an electro-magnetic circuit when a lap forms on a delivery roller and a roving trap is brought into operation, whereupon the electromagnetic circuit is immediately broken. When a lap builds on roller 1, detector limb 3, adjustable in position by a stop 5, is raised and detector tail 4 engages a contact 8 to close the circuit of an electromagnet 17, which releases a finger 13 to fall against a steel cylinder 9, thereby trapping the roving R. When finger 13 falls, a pair of spring contact blades 21 separate and open the electromagnetic circuit.
Patent GB-517551-A (GB)
Title: Improvements in or relating to electrical compasses for air or other craft
IPC: G01C17/36
Filed: 1938-07-29
Abstract: 517,551. Magnetic tests. SHEVLIN, J. T. (Siemens Apparate und Maschinen Ges.). July 29, 1938, No. 22679. [Class 37] An earth-inductor or other compass having a non-oscillating system is arranged to indicate only when it passes through the horizontal position determined by an artificial horizon, for example a gyroscopic horizon, the supports for the compass and artificial horizon being relatively fixed. An earth inductor compass 1 comprises field collectors 1a between which a coil 1b is rotated by a motor 2. The entire compass is mounted on the air or other craft at 3 and is adjustable for the required course by a wormwheel 1c, Fig. 1. An indicating instrument 4 is connected to the terminals of the coil lb through a switch 5, the parts 5a of which are fixed while the part 5b is carried by an artificial horizon 6. The switch 5 is closed only when the apparatus is in the horizontal position. The longitudinal inclination of the compass may be adjustable. The instrument 4 may give the mean value of the individual impulse, or it may be a normal voltmeter, provided with a dropping member which releases it during the closing period of the switch 5 and holds it in the last indicating position during the transmission pauses. The switches 5 may be controlled from the artificial horizon by a vane moving in a beam of light, a ray of heat, or a jet of air. Alternatively the instrument 4 may be connected directly to the earth inductor compass, the switch 5 then controlling a signal or a diaphragm covering the instrument 4 during the pauses. The whole apparatus may be oscillated in a vertical plane to render the reading independent of the period of oscillation of the craft. A modification suitable for automatic control is shown in Fig. 2, in which the moving coil 10a of the measuring instrument 10 is connected through a contact 11a of a relay 11 and through an amplifier 12 to the terminals of the earth inductor compass 1. On the spindle of the moving coil 10a is a pointer 10c and also an electrode 10d rotatable in a casing 13 filled with electrolyte between two fixed electrodes 13a, 13b. The electrodes 10d, 13a, 13b are connected to the course-controlling apparatus. The spindle of the moving coil 10a is controlled by a spring 10e and also carries an eddy-current damping device 10f, the winding 10g of which is connected to a D.C. source of current through a contact 11r of the relay 11. The winding of the relay 11 is connected through an amplifier 14 and the contacts 5a controlled by the artificial horizon 5 to a source of voltage 16. When the apparatus passes through the horizontal position the relay 11 closes the circuit of the moving coil 10a and opens the damping circuit, these operations being reversed on departure from the horizontal position. The instrument thus maintains its previous position during the pauses. In an alternative arrangement the moving coil 10a may directly control the automatic control gear, the electrodes 10d, 13a, 13b being dispensed with.

A night-viewing telescope system comprises a passive night telescope, an infra-red search light and an infra-red unit which receives an infra-red image of the scene irradiated by the search light and converts it into a visible image. The passive night telescope comprises a high aperture front objective 4, 5, 6, 7, 8, Fig. 1, which projects an image of the scene on the photo-cathode of a first image intensifier tube 9 which is non-sensitive to infra-red rays. A pair of similar objectives 10 and 11, between which the light beams are parallel, image the anode screen of tube 9 on the photo-cathode of a second image intensifier tube 12, and the anode screen image of tube 12 is viewed through a magnifier 13. The infra-red unit comprises an image converter tube 17 with a photocathode sensitive to infra-red rays, a front objective 18 whose optical axis is parallel to the optical axis of the front objective of the first image intensifier tube, and a collimation objective 16 having its focal plane coinciding with the image screen of the image converter tube. By means of a mirror 15 hinged at 14 the screen of tube 9 or of tube 17 is coupled optically on to the photo-cathode of the second image intensifier tube 12. Changing over from one image to the other involves turning mirror 15 through 45 degrees (or sliding a mirror between two locations) and switching on or off image tubes 9 and 17 and the search light.

Title: Method and apparatus for twisting insulated conductors for use in multiconductor communication cable into quads
IPC: H01B13/02
Filed: 1975-05-23
Abstract: 1503606 Stranding star quad communication cables FUJIKURA CABLE WORKS Ltd 23 May 1975 [28 June 1974 29 July 1974] 22756/75 Headings D1J and D1T [Also in Division H1] Insulated conductors are twisted into cables by:-(a) Using four stationary pay-off bobbins, one for each insulated conductor; (b) Twisting each conductor as it is drawn off its bobbin alternately in the S and Z direction; (c) Dividing these pretwisted conductors into two groups such that the twist reversal positions of the insulated conductors of one group are shifted relatively to the twist reversal positions of the other group; and thereafter; (d) Twisting the two groups of insulated conductors together into a star quad. Fig. 1 shows four stationary pay-off stations 21A; 21B; 21C; 21D at each of which there is one operative supply bobbin 28 the tail end 28b of which is coupled to the leading end 28a of the next bobbin to be unwound. Paired conical hoods, Fig. 2 (not shown), are positioned above each pair of bobbins. Each of the four conductors is drawn through a separate one of four pre-twisting devices 55, 56, 57, 58 at a station 12 such that each conductor is twisted alternately in the S and Z directions. Each of the four pre-tensioning devices 55 to 58 contain a plurality of conductor accumulating pulleys Fig. 4 (not shown). A common reverse control device 112 operates each time the conductors have been advanced by a length equal to the length that can be stored on the accumulating pulleys of the devices 55 to 58 so as to reverse the direction of twist. Two of the conductors issuing from the pre-twisting station 12 pass over a shift roller 141 that is movable up and down a rod 140 so as to shift the twist reversal point of two of the conductors relatively to the twist reversal points of the other two conductors. All four pretwisted conductors are then fed into a 2-for-1 twister 13 and are wound up on a take-up drum 182 carried by a floating cradle 156 in the twister 13. The twister 13 includes a draw-off capstan 179 and traverse rolls 185, 186 for feeding the communication cable onto the drum 182. Pay-off stations. Rotatable guide rings 32, 33, Fig. 1, are removably secured to the shafts 26, 27 on which the supply bobbins are mounted. The purpose of the guide rings is to frictionally engage and guide the insulated conductor 28 of the supply bobbin as it is drawn off overend from the bobbin, rotation of the guide ring with the conductor around the supply bobbin preventing damage to the insulated conductor. The reference numeral 35 indicates a hood that reduces the ballooning effect of the conductor when drawn off at high speed.

Patent GB-878007-A (GB)
Title: Flame thrower
IPC: F41H9/02
Filed: 1951-10-01
Abstract: 878,007. Flame throwers. CANADA, MINISTER OF NATIONAL DEFENCE. Oct. 1, 1951 [Aug. 3, 1951], No. 22863/51. Class 119. A flamer thrower comprises a barrel 10, a pintle 29 guided by vanes 33 and movable as a unit within the barrel, a pintle piston 35 with an enlarged head 36 movable within a cylinder block 22, the latter being secured to an elbowshaped gun body 16 to which the flame fuel is supplied, and means for supplying and exhausting gas to and from the cylinder 39 of the block 22 in order to prevent or allow the flame fuel to be ejected past the conical tip 31 of the pintle. In the construction shown, the body 16 is pivoted at 40, 40a, to the arms of a stirrup 42 which is pivoted at 43 to a bar 44, the bar being connected to a supporting structure by screw and slot connections 45, 46. Near one of the controlling hand grips 82, 83, is a trigger 85 which, when pulled, produces three results in timed sequence. The first result is to retract, by means of a piece 90 on the trigger rod 84, a spindle 91 whose bevelled surface 94 then serves to close a micro-switch 95. Cables 122 lead from this switch to electrodes 134, 135, to produce a continual electric spark against a petrol nozzle of an ignition assembly 123 near the forward end of the barrel 10. The second result is to permit the supply of petrol to the ignition assembly by way of a conduit 121 from a'supply source connected at 101, Fig. 3, to a control block 48, which is secured to the cylinder block 22. The flow is normally prevented by a valve 100 on a valve stem 93, but when the trigger is pulled and immediately after the closing of the micro-switch 95, a face 116 of the spindle 91 engages adjustably positioned nuts 117, 118, on the valve stem to open the valve. The petrol issuing from the petrol nozzle is ignited by the spark. The third result produced by continued movement of the trigger is to release the normal supply of gas under pressure to the cylinder 39 and to open the communication between the cylinder and the atmosphere. As shown in Fig. 3, the control block 48 has a cylinder 57 which communicates at 50 with the cylinder 39 and which is fitted with a valve body 61 having a groove 75 which normally communicates with a supply of pressure gas. The gas reaches the cylinder 39 by way of ports 76 and bore 62 in the valve body and thence by way of the passage 50. When the trigger is pulled a screw 87 carried by a plate 851 at the end of the trigger rod acts on a rod 65, which serves to move the body 61 so that groove 75 no longer registers with the gas supply and which at the same time connects the cylinder 39 with the atmosphere by way of passage 50, bore 62, radical bores 77 in the valve body, a space 78, a bore 70 of a valve plug 66, and radial bores 69 in the head of the plug. The pressure of the flame fuel in the barrel 10 by pressing on the front face of the pintle piston 35 can now move the pintle rearwards to enable the fuel to issue from the nozzle tip 14 and to become ignited by the ignition flame.
