Title: Improvements relating to distributor valves for fluid pressure brakes
IPC: B60T13/24
Filed: 1945-07-16
Abstract: 603,171. Compressed air brakes. SERVOFREIN DEWANDRE SOC. ANON. July 16, 1945, No. 18164. Convention date, Jan. 30, 1943. [Class 103 (i)] A manually-operated self-lapping control valve suitable for brake systems comprises two pistons connected to each other and to the pedal or the like by linkage in which a resilient means is interposed, the pistons being respectively subject to the maximum fluid pressure and to that in the operating cylinder supplied by the valve. The pedal may thus be moved further, after the maximum pressure has been set up in the operating cylinder, against a constant resistance from the valve and when the valve controls trailer vehicle brakes, this further movement may apply mechanicallyoperated brakes on the tractor vehicle. Pistons 11, 16 are slidable in chambers 7, 8 connected at 9, 10 respectively to a compressed air source and to a brake-operating cylinder for a trailer vehicle. Piston 16 carries the seat 17 for an exhaust valve 22 which has lost-motion connection with a supply valve 21, the valves being slidable in housings on the fixed partition 20. The pistons are interconnected by levers 13, 28 and link 36 in which is interposed the spring device 37. Lever 13 is pivoted at 14 on fixed bracket 15 and lever 28 is connected to the pedal upon operation of which, lever 28 at first pivots at 34, thus seating valve 22 to close the exhaust passage 18 and opening valve 21, permitting compressed air to flow from chamber 7 to chamber 8 and the brake cylinder. If the pedal is held against the cylinder pressure acting on it through the piston 16, this piston returns sufficiently to close the supply valve 21, the lever 13 remaining stationary and lever 20 pivoting at 30 and extending the spring device 37. The cylinder pressure may thus be graduated. When the maximum pressure is reached in the chamber 8 and the cylinder, the part 38 abuts on the casing of the spring device 37 so that the link 36 is no longer extensible and as inward movement of the piston 16 is limited by a stop 25, further movement of the pedal results in movement of the piston 11 against the constant pressure of the source acting on it. As shown, the pedal is connected by mechanical means to the brakes 40, 41 of the tractor vehicle, the shoes of which are brought up to the drums while the trailer brakes are being applied so that further pedal movement after the maximum trailer brake pressure has been reached effects application of the tractor brakes. The spring device 37 may instead be disposed between either piston 11, 16 and its lever or in the link 32.

Abstract: 1370461 Splicing webs AGFA-GEVAERT AG 16 April 1973 [22 April 1972] 18213/73 Heading B8R To prevent traction forces being applied to the ends of remnant webs during splicing by an adhesive tape dispenser which traverses the abutting webs to apply adhesive tapes 14 to both sides of the joint, clamping means 16 are provided to hold the protruding ends of the tapes adjacent one edge of the joint whilst the tape is applied across the joint. The web ends are manually placed against an end abutment 10, Fig. 1, on a suction table 7 and two cutters each comprising fixed and rotatably mounted knives 8, 9 are operated to cut off the end portions. The webs, now held by suction on horizontally movable suction tables 4, are advanced until the newly cut ends abut, the table 7 having been lowered and the cut web portions blown off. The tape dispenser, mounted on a bracket 13a, Fig. 2, is then moved across the joint and when the adhesive tapes 14 engage the surfaces of the webs, the resulting friction causes the tapes to be unwound from their reels 12, 13, the tapes being pressed on to the joint by rubber rollers 15 whilst their free ends are held stationary by a clamp 16. The tape ends are then cut by knives 19, the spliced web wound up and the clamp and dispenser returned to their inoperative positions.

Title: Improvements in and relating to hydrogen generators
IPC: C01B3/06
Filed: 1918-11-09
Abstract: 142,882. Griggs, A. R. Nov. 9, 1918. Hydrogen. - In generators for producing hydrogen by the iron-steam process and in which the ore chamber B surrounds an inner heating-chamber J, the gases for heating this chamber are burnt in a separate chamber D provided at its lower end and below the level of the ore in the chamber B; to secure complete combustion, the gas and air are led in through relatively inclined passages. By this arrangement, combustion in the chequer brickwork, with consequent local overheating, is obviated. In the construction shown in Fig. 1, the heating-gas enters through a central passage C with a flared mouth, and the air is supplied through an annular passage E the end of which is inclined relatively to the central passage; to facilitate still further the rapid mixing of the gases, the air may be given a swirling motion by supplying it tangentially to the box constituting the lower part of the passage E; or the air may be supplied through the passage C and the gas through the passage E. In another construction, a fire-brick deflecting-cone K, Fig. 2, is provided at the upper end of the passage C. Mingling of the gases may be further promoted by reducing the cross-sectional area of the upper part of the combustion chamber D, as shown. The gases from the combustion chamber pass through the chequer brickwork J arranged so as to provide larger gas-ways adjacent to the liner A, giving a greater heat storage at these parts. The liner A is protected by a fire-brick lining I.

Abstract: 1389515 Friction clutches DEERE & CO 19 April 1973 [20 April 1972] 19065/73 Headings F2C and F2L In a vehicle having a rotary drive member 18, 62, 74 and a dual clutch for transmitting the drive to coaxial shafts 22, 26, the friction discs 56, 58 of the clutches are disposed adjacent a backing plate 60 and pressed independently into engagement therewith by first and second hydraulic actuators 98, 100, and a valve 126 controlling flow of cooling and lubricating fluid to the clutches is operated in response to pressurization of the actuators. In the embodiment described the shaft 22 is the propulsion input shaft of a tractor and the shaft 26 leads to a power take-off. The friction discs 56, 58, which have drive connections with hubs 40, 42 secured to the shafts 22, 26, are urged into engagement with the backing plate 60, against release springs, by the actuators, which are of annular form surrounding the shaft 26, acting through levers 82, 84 and pressure plates 68, 70. Each actuator is controlled by a valve 122, 124, and lines 154, 156 communicate the pressures applied to the actuators to ports 136, 138 of the valve 126. When the actuator 98 is pressurized, pressure in the line 154 raises the valve spool 140 against a spring 148 to close an exhaust port 134 and open an outlet port 130 through which cooling and lubricating fluid from a pump 162 is supplied through a line 164 to ports 168 in the shaft 26 and thence through ports 172 to the clutch disc 58 and through a restriction 180 to ports 178 and the clutch disc 56. When only the actuator 100 is pressurized the pressure in the line 156 acting on a plunger 158 raises the spool to an intermediate position so that a restricted flow is delivered to the line 164 and, owing to the restriction 180, only the clutch disc 58 receives any substantial supply of fluid.
