Title: Anti-Cornering for Railway Classification Yards
IPC: B61L17/00
Filed: 1969-03-13
Abstract: 1,191,999. Points control system. WESTINGHOUSE AIR BRAKE CO. 13 March, 1969 [13 March, 1968], No. 13300/69. Heading B7H. In an arrangement in a hump-type classification yard for preventing a first cut of vehicles taking a first route from a set of points being cornered or struck by a following faster moving cut taking the second route before the routes diverge sufficiently to prevent such happening, the time interval required prior to the arrival of the second cut at the points to prevent cornering is determined and the operation of the points is delayed for this period. The time interval is determined in computer means which determines the difference in time for the first and second vehicles to traverse the cornering zone CF, CG. The speed of the first vehicle is determined at position C by means for timing the passage of the cut and from information stored in the computer relating to the length of the cut (see Specification 1,191,999). The speed of the second cut is its leaving speed at the preceding master or group retarder. The delay which is applied to the points operating circuit commences as the last axle of the first cut leaves point C. If the leading axle of the following cut has reached the points track circuit B, D, E by this time then the points remain locked in the first route position and the second cut is routed incorrectly to follow the first thus preventing a cornering collision.

Abstract: 740,639. Tunnel kilns. CREMER, G. May 15, 1953 [May 21, 1952; May 29, 1952], No. 13728/53. Class 51 (2). [Also in Group XIII] In a combined tunnel kiln and drying chamber in which hot water from pipes in the cooling zone of the kiln is used to heat the drying chamber, the heat deficiency is made up by hot water from either a separate boiler or water tubes disposed in either the preheating zone or the firing zone of the kiln. The amount of extra heat supplied is controlled in accordance with temperature conditions in the drying chamber or chambers. The amount of heat given up to the water tubes may be regulated by adjusting ceramic screens in front of them. The drying chamber is heated by pipes, preferably ribbed, of such length or construction that the temperatures of the chamber and of the water, which is re-circulated back to the heat source, are substantially equal. The invention may be applied to tunnel kilns in which the heat is supplied by combustible substances mixed with the charge.

Abstract: 1,163,723. Steering by differential braking. INTERNATIONAL HARVESTER CO. 16 Sept., 1966 [9 Dec., 1965], No. 13833/69. Divided out of 1,163,722. Heading B7H. [Also in Division F2] In a braking system for a vehicle (Division F2) having a pair of transversely spaced wheels 12, 14 individual brake pedals 28, 30 are associated with respective brake means for each wheel of the pair such that actuation of one brake pedal effects consequent braking of one wheel only to produce a steering action on actuation of both brake pedals with the consequent braking of both wheels produces a stopping action. In the embodiment shown in Fig. 2 a single master cylinder 102 is adapted to be actuated by brake pedals 28 and 30. Valve means 108 and 110 are internally biased to a closed position and control the flow of fluid to the respective brakes 32 and 34 associated with the driving wheels 12 and 14 respectively. If one brake pedal 28 is actuated, the brake rod 44 actuates a plunger plate 92 to pressurize the master cylinder 102 through a master cylinder plunger 104 and the brake operating rod 44 actuates the valve means 108 to permit fluid to flow from the master cylinder to the brakes 32 whilst the other brake 34 is not actuated. When the brake pedal 30 is actuated, the valve means 110 is opened and only the brakes 34 are applied for steering purposes. Simultaneous application of both pedals 28 and 30 actuates the brake rods 44 and 46 and brake operating plunger 104 such that both brake valve means 108 and 110 are opened to allow both brakes 32 and 34 to be operated for general braking of the vehicle. In a second embodiment (Fig. 3) two master cylinders 36, 38 are provided and two normally closed valves 134 and 136 are arranged in series and interposed between the brake lines 64 and 66. Associated with the valves are first brake rods 44 and 46 actuated by the respective pedals 28 and 30. The master cylinders 36 and 38 are actuated by second brake rods 138-140. Upon actuation of either brake pedal alone, the corresponding valve 134 or 136 is opened but the other is closed and the corresponding master cylinder 36 or 38 is actuated to apply the corresponding brake. When both brake pedals are applied simultaneously, both valves 134 and 136 are opened to establish communication between brake lines 64 and 66.

Title: Improvements in wringers
IPC: D06F45/18
Filed: 1939-05-09
Abstract: 529,585. Wringers; machinery guards. LOVELL MANUFACTURING CO. May 9, 1939, No. 13865. Convention date, May 11, 1938. [Class 138 (ii)] [Also in Group XXIV] A power operated wringer is hung on parallel links pivoted at their upper ends to a mounting head for movement about horizontal axes and permitting of the wringer having moved laterally to actuate a safety device for releasing the pressure between the rollers and disengaging the drive. The wringer is supported by a pillar 36, Fig. 1, mounting a swivel head 37 on which parallel links 67, shown also in Fig. 4, are mounted by horizontal pivots 65 and carry by horizontal pivots 66 a gear box 39 to an extension of which the stile 3 of the wringer is secured. Power is transmitted from a motor or a washing machine through the shaft 46, coupling 45, bevel gear 42, 51 and dry clutch movable by a head piece 63 to a splined shaft 52 which drives the lower roller as described in Specification 529,378 through a flexible coupling 18 and a cone shaped clutch member 9 engaging a pin 13 on the roller shaft, the member 9 resting on an inclined bearing 10 in the stile 3 and enclosing a spring tending to disengage it from the pin 13. The wringer cap 23 is held down, applying pressure through the screw 22 and spring 21 to the rollers, by a toggle 32, 34 at one end and by a catch 25a mounted by a pivot 26 to the cap and engaging a recess 24 in the stile at the other end, the catch being retained by its tail 28 bearing against the inturned end 31 of a rod 29 whose other end 70 engages a fork 71 in a bracket secured to the head 37. When it is desired to release the pressure on the rollers, e.g. in case of the fingers being trapped, the wringer frame is pulled or pushed, causing it to rock laterally on the parallel link suspension whereby the fork 71 rocks the rod 29 so that its end 31 releases the catch 25a and the toggle 32, 34 can then release the pressure on the rollers. This permits the spring within the member 9 to draw it along the inclined bearing 10 and disengage from the pin 13, thereby arresting the drive of the roller. Springs 69 between extensions of the parallel links and the gear box 39 tend to return and centralize the wringer to its operative position after replacement, and the pressure is re-applied and the catch reset by operating the toggle. Specification 529,586 also is referred to.

Abstract: 833,050. Batteries. BURNDEPT Ltd. Aug. 1, 1958 [May 1, 1957], No. 13925/57. Class 53. A cell consisting of a metal electrode 5, a sheet of absorbent paper 4, and a depolarizer 3 is provided with a casing by placing the elements of the cell on a plastic sheet 1 and applying a covering 6 of plastic material in liquid form or as a sheet or ribbon sufficiently plasticized to sink over the edges of the elements and adhere to the sheet 1. A gas space 8 is left in the cell. A continuous method of providing cases for a number of cells consists in passing the plastic sheet beneath punches to make holes 2 above which the cell elements are placed. The sheet is then passed under, a nozzle which sprays plastic material over the cells and the adjacent parts of the sheet 1. The electrode 5 is exposed through an opening made in the plastic by a tube bevelled at its lower end. Fig. 3 shows'an alternative method in which a viscous plastic issues from a hopper 9 between rollers which spread the plastic into a sheet or ribbon which covers the cells and adheres to the sheet 1 which may be heated or treated with a solvent to form a weld with the plastic covering. Apertures are made in the cover to expose the metal electrode, and these apertures and the holes 2 may be filled with a conductive plastic. The whole of the sheet 1 may be made of conductive plastic, in which case the holes 2 may be dispensed with. The spraying process may be performed with the use of a static electric field whereby the material to be sprayed is flung off the edge of a rotating disc which is kept at a high potential.
