Title: Improvements in starting gates for race horses
IPC: A63K3/02
Filed: 1925-10-20
Abstract: 250,116. Esquerre, 31. Oct. 20, 1925. Starting-gates for horse races.-In apparatus of the kind where electrically-released tape carriers 6 move in an inclined plane between posts 1, 2 of unequal height, the carriers move on pairs of guide rails 4, 5 arranged within a hollow guide member 3 connecting the tops of the posts, and are impelled upwards by springs 8 wound round the rails 4, 5. The springs are connected at the top to the member 3 and at the bottom to the carriers. Cleats 28 secured to cables 26 bring the carriers 6 to the bottom of the guides, where a latch 11 on an electric or pneumatic releasing device 12 engages a catch 9 on each carrier, and the cleats are returned to the top position by means of a spring drum 13 round which the cable 26 passes. The lower end of the cable is wound round a second spring drum 22 of less tension than the first, and the cable is released by means of a pawl lever 25 engaging a ratchet wheel 24. The tension of the drum 13 may be regulated by turning the spindle 15, and the drum 22 is turned to lower the cleat 28 and the carrier 6 by means of a crank-handle placed on the spindle 33. A rubber buffer 29 takes the shock of the carrier and cleat. Instead of the springs 8 for impelling the carriers 6, an arrangement of cables similar to that for the cleat 28 may be employed.

Title: Improvements in or relating to mechanical loading shovels and the like
IPC: E02F9/20
Filed: 1947-09-30
Abstract: 634,455. Load-handling machines; winding gear. BOYDELL & CO., Ltd., E., and JOLLY, B. N. Sept. 30, 1947, No. 26341. [Classes 78 (iii) and 78 (v)] In a load handling device such as a mechanical shovel, in which an implement is raised to discharge its load and then lowered under control of a winch, and in which the winch is controlled by a lever which engages a clutch to drive the winch when moved in one direction, has a neutral central position in which the implement may fall under its own weight and is biased by a counter-weight to move in the other direction to apply a brake to the winch, the brake releasing action of the lever is automatically overridden when the implement engages a trip member near the end of its descent. As shown the invention is employed in a mechanical shovel of the kind described in Specification 579,553. The winch a is mounted on an eccentric shaft b to move so that its flanges engage either a friction driving roller c or a brake shoe d. The winch is controlled through a linkage e, f from a lever g having a pin g<SP>1</SP> which engages in L-shaped slots h<SP>1</SP> in the bifurcated head k of the link f. Normally the pin g<SP>1</SP> lies in the vertical parts of the of the slots h<SP>1</SP> so that movement of the lever g about its pivot g' controls the winch a, but operation of a trip member m by the front guide rollers o of the implement moves a lever j, also pivoted at g<SP>2</SP>, through a link k, to introduce a roller j<SP>1</SP> under the head h so that the pin g<SP>1</SP> engages in the horizontal parts of the slots h<SP>1</SP> permitting the counterweight p to apply the brake. If the implement stops completely when the trip m is operated, it may be released by moving the lever g so that the pin g<SP>1</SP> engages the extreme ends of the slots h<SP>1</SP>. Specification 593,696 also is referred to.

Filed: 1928-09-20
Abstract: 323,210. British Celanese, Ltd., and Felgate, R. S. Sept. 20, 1928. Printing processes; embossing.-Fabrics made of or containing cellulose esters or ethers are embossed and have effect or other materials applied locally by means of a roller or other device adapted to contact only with the raised portions of the fabric. The fabric may be passed from a roll 1 to embossing-rollers 2, 3, which may be steam-heated, and then round a plain roller 4 where the effect material is applied by a roller 5 running in contact with a roller 6 rotating in a vat of the effect material. Alternatively the effect material may be applied while the fabric is on the embossing- roller. Gum or the like may be applied to the fabric-supporting roller to impart increased rigidity to the fabric while applying the effect material. The effect material may be a saponifying agent such as caustic soda made into a paste with water and potato flour. After application, the fabric may be passed round rollers 9 or through a heater, to enable saponification to take place, and then through an open soaper 9.' After washing and drying the fabric may be treated to produce cross-dyed effects. When vat or sulphur colours are employed, baths of reduced alkalinity, as described in Specification 262,506, are employed. In an example, the fabric is treated with a solution of sodium p-cresolate to which is added Caledon jade green paste and sodium hydrosulphite powder, then with an oxidizing-solution containing olive oil soap and sodium perborate, and then with a solution containing 1-amino-2-methylanthraquinone and 1-methylamino-4-hydroxyanthraquinone. If desired, the dyestuff and saponifying-paste may be applied together, or the saponifying-paste can be replaced by a resist, either mechanical or discharge, and coloured or not. Gum or adhesive may be applied locally, and the fabrics sprayed with pigments, metal powders, dyestuffs, &c. The relief may be finally suppressed by calendering over blanketed rollers.
