Title: Improvements in or relating to safety guards for mixing machines
IPC: F16P3/08
Filed: 1926-03-31
Abstract: 270,469. Richmond &. Chandler, Ltd., and Jackson, N. W. March 31, 1926. Interconnecting guard with starting-gear.-In guards for tilting-container mixing-machines, the pivoted lid 11 of the pan 8 is held closed by the engagement of a lug 12 at its hinged end with a weighted locking-quadrant 13, which is pivoted in a housing 14 on; the. pan and is laterally shiftable into and out of the path of the, lug by means interlocked with the starting-gear, but allows limited opening of the lid, with the blades running, when the pan is tilted. The part 13 is drawn against spring pressure into engagement with the lug 12 by a Bowden. wire connected to a hand-lever 21, which, when so actuated, is withdrawn from a notch 20 in a belt-shifter bar 18, allowing the machine to be started. If the lid is open, the lever 21 cannot be moved to free the bar 18, due to lateral obstruction of the part 13 by the lug 12, and the part 13 cannot be released while the belt is on the fast pulley. On tilting the pan 8, as shown in Fig. 7, the catch 13 swings to allow restricted opening of the lid 11 for discharging purposes. Wings 22, Fig. 2, carried by the machine frame 7, mask the opening laterally, and carry rollers 23, which assist in closing the lid when the pan is restored. The belt,shifter may be replaced by gear-control or eleetromotor starting means, and the Bowden wire bv rod mechanism; in an electrically-driven machine, the locking-quadrant may be actuated electrically, the controlling-switch being interlocked with the motor-control. The Provisional Specification describes a form in which the quadrant is spring-urged into locking-position.

Title: Improvement in method of making ductile laminated metal
IPC: B23K20/227
Filed: 1939-03-18
Abstract: 526,525. Making aluminium coated ferrous metal. REYNOLDS METALS CO. March 18, 1939, No. 8737. Convention date, April 4, 1938. Drawings to Specification. [Class 83 (ii)] In a method of treating aluminium-coated ferrous metal, the material is rolled at a temperature below that at which there is material increase in the dispersion of the component metals so as to reduce its thickness by more than 35 per cent. preferably 50 per cent. and is then annealed. The rolling is preferably carried out in three stages, each of which reduces the thickness of the laminated metal by from 15 per cent. to 20 per cent., the temperature being below 1000‹ F. The annealing may be at a temperature of about 1000‹ F. This treatment is stated to increase the ductility of the laminated metal by breaking up the intermediate layer of ironaluminium alloy which is less ductile than either of the component metals. The initial rolling operation serves to break up the alloy layer into a number of blocks which become separated and rotated during subsequent rolling.

Title: Improvements in or relating to liquid dispensing apparatus
Inventor: FRASER JOHN
IPC: B67D7/48
Filed: 1953-03-30
Abstract: 735,364. Fluid-pressure servomotor-control systems. AVERY-HARDOLL, Ltd. March 29, 1954 [March 30, 1953; July 1, 1953], Nos. 8746/53 and 18266/53. Class 135. A hosecock for a liquid dispensing apparatus comprises a main valve 17 coacting with a seat 18 between an inlet 12 and an outlet nozzle 14, a pilot valve 24 actuated by a hand-lever 15 coacting with a lever 61, and an auxiliary pilot valve 34 operable by suction due to the stoppage of a flow of air when an air opening 41 is submerged by the rising level of liquid in a tank being filled whereby to cause closure of the main valve. Inlet pressure has access through a small opening 56 to a chamber 21 where it acts on the main valve in the closing direction. When the lever 15 is operated to open the pilot valve 24 the pressure in chamber 21 is released through a port 23, moving the valve 34 against its loading spring 38. The pressure liquid so released then escapes to the nozzle 14 through ports 32, and the main valve is opened, to an extent determined by the degree of opening of the pilot valve 24, by inlet pressure acting on an annular area of the valve surrounding a sealing ring 27. Some of the liquid discharged passes through ports 44 to an annular passage formed between a venturi 28 and a pipe 39 thereby inducing a flow of air from the opening 41 to the pipe 39 and thence through a ribbed, annular passage between a member 37 and the pipe 39 to the throat of the venturi. When the opening 41 becomes submerged the venturi causes a suction to be applied behind the valve 34 to cause the latter to move fully to the left to close the ports 32 and cut-off the escape from the chamber 21 thereby causing the main valve to close.

Title: Stereoscopic projection
IPC: G03B35/00
Filed: 1943-06-01
Abstract: 571,946. Stereoscopic kinematography. BRITISH THOMSON-HOUSTON CO., Ltd., and CASTELLAIN, A. P. June 1, 1943, No. 8766. Drawings to Specification. [Class 97 (i)] A stereoscopic projection system in which multiple images taken from spaced view points are projected and viewed, either successively or simultaneously, through a vertical line screen, comprises means for moving the film bearing the images at a uniform speed in front of a light spot which scans it transversely, a photoelectric cell subjected to the light beam passing through the film and controlling the beam of a cathode-ray tube, on the screen of which the multiple images are reconstituted as separate images, and means for projecting these separate images from corresponding spaced points through the line screen on to the projection screen. When the multiple images, which may consist of a pair corresponding to right- and left-eye views, are to be projected simultaneously they may lie side by side transversely of the film, or may be interlaced in a single image ; in either case, if vertical scanning is adopted, the vertical dimensions of the images must be transversely of the film. When the images are projected in succession, they are arranged one above the other in the normal manner. The light spot may be provided by the beam of a cathode-ray tube oscillated by a saw-tooth oscillator which also provides the horizontal scans of the beam of the tube in which the images are reconstituted. The vertical scan of the latter may be effected by a current or potential derived from a motor which feeds the film. Projection may be effected by an auxiliary light source controlled in known manner by the images on the screen of the cathode-ray tube. The line screen may be oscillated from side to side to enable a larger part of the spectators to obtain a stereoscopic effect. For the projection of coloured images, a segmented colour disc may be rotated in the path of the image beams. The images may be formed on the film by the system described in Specification 571,945.

Filed: 1966-03-02
Abstract: 1444531 Sighting device DEFENCE SECRETARY OF STATE FOR 3 March 1967 [2 March 1966] 9246/66 Heading F3C [Also in Division G2] A sighting device whereby a lead can be applied to a gun to allow for movement of the target comprises a sighting telescope of known type including an objective prism 1, a focusing lens 2, prism system 3, graticule 4 constituting the image plane and an eyepiece 5. A semitransparent mirror 6 set at 45 degrees to the telescope axis reflects rays originating from a spot source of light 7 constituting a sighting datum to form further images 15 on the graticule 4. The light beam from the source 7 is rendered parallel by a collimator 8 and then passes to a beam dividing and inverting device 9, one part 10b of the beam reaching the mirror 6 directly, the other part 10a being inverted by passage through a pair of porro prisms 9a, 9b giving image inversion in two mutually perpendicular directions. The two images 15 formed by the two parts 10a, 10b can be rendered non- coincident on the telescope axis by rotating one or both of two transparent deflector plates 11, 12 rotatable about mutually perpendicular axis 13, 14. Movement of one image 15a to a desired position is accompanied by a corresponding movement of the other image 15b in the diametrically opposite direction, Fig. 3. In operation the coincident images 15 of the datum 7 are first laid on the moving target in an initial position by means of the gun aiming equipment. After a period of time equal to the flight time of the projectile to the target, the target position is noted and one image 15a of the datum 7 is moved to this position by manipulation of the deflector plates 11, 12, the gun meanwhile remaining laid on the initial target position. Then, maintaining the relative positions of the two datum images 15a, 15b the second image 15b is laid on the moving target, by manipulation of the gun aiming equipment, to apply the correct lead to the gun. If desired, shutters may be introduced so that either of the datum images 15a, 15b may be obscured while manipulating the other. In modifications, instead of using deflector plates to produce the required image displacement, the datum itself may be made movable. This may be achieved either by moving the spot source as a whole or by moving a shutter, incorporating a suitable aperture, in front of a fixed light source. The displacement may alternatively be achieved by moving the collimator.
