The carriage 3 of a mobile elevator, comprising guide rails 2 mounted on a frame 1 provided with retractable wheels 30 and castors 29, is provided with catch gear to prevent descent of the carriage on breakage of a hoisting cable 10, which passes from an anchorage on the carriage around a pulley 9 mounted on the piston rod 8 of a hydraulic ram 7 to an anchorage 11 on the frame 1. The catch gear comprises a rack 12, secured to one of the guide rails 2, and a sliding bolt mounted on the carriage and spring-urged towards the rack. The bolt is connected to the cable 10 and is thereby held out of engagement with the rack when the cable is tensioned. The carriage is provided with an operator's platform 4, having controls, for raising and lowering of the carriage, and with a load platform 5. A frame 23, which is pivotally mounted beneath the platform 4, is adapted to actuate a micro-switch 26 to stop descent of the carriage on engaging an obstruction. As the carriage descends to its lowermost position, it engages arms, pivoted at 36 to the frame and supporting the axle of wheels 30, and pivoted arms 33, supporting the castors 29, and thereby lowers the wheels and castors and raises legs 28 of the frame 1 from the ground. In a modification, the wheels 30 are driven and the wheels 29 are steerable, controls therefor being provided on the platform 4.

Title: Improvements in the coloration of cellulosic materials with vat dyes
Inventor: KRUG PAVEL
IPC: D06P1/22
Filed: 1950-06-21
Abstract: Cellulosic materials are treated to form within them a fine dispersion of a vat dyestuff by causing an acid leuco vat dye, with which the material is impregnated, to oxidize to the vat dye, the acid leuco vat having been prepared by reducing the vat dye with thiourea dioxide.  The material may be impregnated with a suspension of pre-formed acid leuco vat dye prepared by reducing the vat dye in the presence of alkali with thiourea dioxide and subsequently acidifying.  A dispersing agent may be present.  In a modification, the material is impregnated with a suspension of vat dye and thiourea dioxide and the acid leuco vat dye is formed in situ by heating the material to at least 80 DEG C in the presence of moisture.  In either case, the material containing the vat dye dispersed therein is then dyed by alkaline reduction of the dye to fix it on the materials; sodium hydrosulphite may be used for this reduction.  In Examples (1), (2) and (3), cotton, linen or spun rayon-wool cloth is impregnated with an acid leuco vat dye prepared with thiourea dioxide, and the material then developed in a bath containing sodium hydrosulphite or thiourea dioxide and finieshed in the usual way; (4), (5) and (6) spun rayon, rayon-wool or cotton cloth is padded with a composition containing thiourea dioxide and a vat dye together with a dyeing assistant and a thickener, steamed at 100 DEG C with saturated steam, and the dyeing developed by means of alkaline hydrosulphite. Specifications 702,040 and 702,041 are referred to.

Title: Improvements in or relating to fluid-flow control valves
Inventor: NORTH JOHN DUDLEY
IPC: F16K11/085
Filed: 1958-05-14
Abstract: 890,722. Valves. BOULTON PAUL AIRCRAFT Ltd. June 25, 1959 [May 14, 1958], No. 15488/58. Class 135.  A valve comprising a cylindrical valve member 1 rotatably or longitudinally movable in a cylindrical housing 2 to control flow between inlet ports 3 and outlet ports through arcuate channels 4, includes a plurality of restricted flow paths connected to a source of pressurefluid and opening at the inner surface of the housing to admit the pressure fluid at reduced pressure to the small clearance between the plug and the housing to reduce static friction. The openings of the flow paths are arranged in rings, one adjacent each end of the valve and each flow path 12 comprises a small bore tube 9 passing through a plug 10 screwed into a housing recess 11. An annular channel 13 between each ring of openings and the ports communicates with an exhaust port 16 through ducts 14, 15 to isolate the controlled fluid at high pressure from the low-pressure fluid issuing from the openings. When the valve is open and the plug is urged towards the outlet port by inlet pressure the reduced flow of fluid through these openings on the outlet side of the valve increases the pressure therein, tending to urge the plug away from the housing wall. In a modification, helical grooves are formed on the outside of the housing and each groove communicates through a radial hole opening into the inner surface of the housing and a sleeve is shrunk on to the outside of the housing to cover the grooves and form the restricted flow-paths.

Abstract: 219,957. Parolini, C., and Perron, G. Aug. 1, 1923, [Convention date]. No Patent granted (Sealing fee not paid). Colour kinematography. -Colour-record kinematograph films having images of half the height oi ordinary monochrome images are projected by an ordinary projector having means whereby the two images simultaneously in the gate are alternately rendered visible on the screen, the screen being large enough to display only one image at a time. Fig. 2 shows a three-colour film in which the images are of half the usual height and are of slightly less width than usual. Fig. 3 shows diagrammatically a projector having an objective 3 of focal length such that the projection screen 4 receives only one of the two images B<1>, C<1> simultaneously projected. A deflector 5 is intermittently moved into the projection beam so as to displace the image C<1> on to the screen during part of the time the film is stationary in the gate. Fig. 6 shows a constructional form of apparatus in which the deflector 5 is mounted at one end of an arm 9 which is rocked about an axis 10 by an eccentric 12 on the shutter shaft. The shutter 7 has two blades and makes one revolution per picture shift. A three-colour screen 8 is so geared to the shutter 7, by wheels 14, 15, 16, 18, that each exposure effected by the shutter is made through a different screen. The deflector 5 may comprise a pair of prisms which are relatively rotatable so as to vary the deflection produced by it. In a modification the deflector may be stationary and cover half the surface of the objective, agreement between the colour of the film images and of the colour screen being relied upon to render the images appropriately visible on the projection screen. In a further modification the projection screen is arranged with its centre on the optical axis of the objective and deflectors are used to displace the images through half their height, the one upwards and the other downwards.

Title: Improvements in or relating to transfer and storage systems for shipping containers or other generally rectangular articles
IPC: B66C17/04
Filed: 1969-03-28
Abstract: 1,267,751. Storage systems; stacker cranes. KAISER INDUSTRIES CORP. 28 March, 1969 [3 March, 1969], No. 16515/69. Headings B8E and B8H. A cargo container transfer and storage system comprises the combination of an array of openended compartments 50 in a storage housing 30 and a stacker crane 36. The crane 36 includes a cage 124 supported for vertical movement from a bridge 100 straddling an aisle 52 and provided with trucks 102 running on rails 104. A mast 108 depends from the bridge 100 and includes guides 114 for the cage 124. The cage 124 includes a pair of end members 128 each with inner and outer legs 130, 132 having foot portions 150 mounting horizontal rails 152. These rails run transversely of the aisle 52 and are alignable with rails 68 in the compartments 50. A carriage 200 is mounted on wheels 226 running on the rails 152. An adjustable lift mechanism 230 is mounted within the carriage 200 and includes a frame with end beams 232 interconnected by side bars 234. Longitudinally adjustable intermediate lift beams 238, 239 extend transversely of the side bars 234 and can be set to particular container sizes (see Fig. 9). Lift cylinders 240 enable the mechanism 230 to be moved vertically with respect to the carriage 200. In operation of the system a container 38 is located on a rail car 34 at a transfer station 82 and the spread of lift beams 238, 239 adjusted to the container size by motor (270), Fig. 7 (not shown). The cage 124 is then lowered over the container 38 so that locking elements 320 enter sockets (92), Fig. 11 (not shown), in the top of the container 38. The lower part 118 of each guide 114 is reduced in size compared with the upper part 116 (see Fig. 5) to allow the cage 124 adequate float for proper location over the container 38 to permit the locking elements 320 to engage correctly, the elements 320 are then twisted to secure the container 38. The lift mechanism 230 is then operated to raise the container 38 relative to the carriage 200. The crane 36 is then operated to bring the cage 124 in line with a selected compartment 50 with the rails 152 in line with the rails 68. The carriage 200 is then extended into the compartment 68, the wheels 226 running over both sets of rails 152, 68 through operation of transfer mechanism 400, Fig. 8. The lift mechanism then lowers the container 38 on to the floor 60 of the compartment 50, the container 38 is released by the locking elements 320 and the carriage 200 withdrawn. Removal of a container 38 from a compartment 50 is the reverse of the above. The operations may be carried out automatically (Figs. 13 to 15 (not shown) illustrate hydraulic and electrical control systems), or semi-automatically under the control of an operator in a control cab 480 or in a control tower (not shown).
