Title: Web tracking mechanism
IPC: F16C13/00
Filed: 1966-03-11
Abstract: 1,108,275. Feeding webs. EASTMAN KODAK CO. 11 March, 1966 [31 March, 1965], No. 10710/66. Heading B6B. A roller 12 for transversely guiding a web 26 comprises a hollow cylinder which is mounted midway between its ends on a shaft 8 with a bearing arrangement (10, 14, 16, 18, Fig. 2). This enables the roller 12 to rotate about the shaft 8 and also to tilt relatively thereto. A web sensing means for sensing the edges of the web 26, and further being responsive thereto to actuate a web travel correcting mechanism for the roller 12 is provided. The sensing means comprises end caps 28 loosely mounted at the ends of the roller, and secured together by rods 30 (Figs. 2 and 4) passing through the bearing arrangement. The end caps 28 rotate with the roller 12 and are axially slidable relative thereto. The correcting mechanism comprises a cam disc 32 loosely mounted on one of the end caps 28 to abut an annular shoulder (31, Fig. 4). The disc 32 is frictionally clutched to the cap 28 by means of a helical spring 34 encircling the cap, and is responsive to both the rotation and axial movement of the cap. The disc 32 has a pair of oppositely directed circumferentially extending cam surfaces 40, 40<SP>1</SP>, and depending upon the direction of rotation of the roller 12, the cam surfaces, slidably engage corresponding pins (44, 44<SP>1</SP>, Figs. 3 and 4) extending from brackets (46) mounted on the machine frame, until one or other of the pins engages the shoulder 42 or 42<SP>1</SP>, Figs. 1 and (3). The pins are adjustably inclined with respect to the axis of the shaft 8 (Fig. 4). In operation, if the web 26 should drift off centre, end cap 28 and disc 32 will also move as a unit causing shoulder 42 to slide along pin (44). Since the pin is inclined, the roller 12 will tilt causing the web to return to its original position. In a modification (Figs. 5 and 6) an enlarged end cap (54) is utilized. A pair of brackets (56) is provided, each co-operating with one of the end caps, and each having pins 44, 44<SP>1</SP> extending therefrom. The brackets are manually movable together so that one or other of the pairs of pins 44, 44<SP>1</SP> is brought into sliding engagement with the end caps, depending upon the direction of travel of the web. In a further modification (Fig. 7) the end cap (54) of (Fig. 6) has a peripheral groove (64) for receiving a roller slidably mounted on each pin (44) or (44<SP>1</SP>).

Title: A supplemental unloading valve for pump systems
IPC: B62D5/06
Filed: 1954-04-13
Abstract: 751,890. Fluid-actuated valves; fluidpressure servomotor-control systems. NEW YORK AIR BRAKE CO. April 13, 1954 [July 20, 1953], No. 10815/54. Class 135. A supplemental pump unloading valve disposed between a continuously-running pump and a negative-lap control valve in an hydraulic system, e.g. an hydraulic servomotor-control system for automobile steering, comprises a housing 32 slidably mounting a piston 37 having reduced ends 38, 39 and a venturi passage therethrough connecting the pump outlet to a line 26 supplying the control valve 40 with pressure liquid. The end 38 constitutes a valve element controlling an unloading passage 33 between the pump outlet and a reservoir 29. Passages 41 in the piston connect the venturi throat to the space behind the piston. The control valve 40 comprises a casing 12 having a supply port 25, exhaust ports 27 connected to the passage 33 and motor ports 30 leading to opposite sides of a double-acting servomotor piston 3 connected by a toothed rack 19 and a sector gear 21 to operate the road wheels. The sector gear engages a nut 17 which in turn engages quick-pitch threads 16 on the steering shaft 4 which passes through, and turns freely on, a tubular piston valve 5 in the casing. The valve 5 is capable of axial movement by means of thrust bearings 6 disposed between flanges 8 on the shaft 4 and flanges 7 on the valve 5. Springs 9 (only one of which is shown) react on plungers 11 to bias the valve 5 towards its mid or neutral position in which position pressure liquid from the supply line passes to both motor parts 30 and both exhaust ports 27 to maintain a continuous flow of liquid between the pump and the reservoir. Ports 14 in the spring chambers permit pressure liquid to react on the plungers 11 to assist the springs 9 so that as the valve is moved farther from its neutral position the centring forces increase and the operator " feels " the reaction to his steering effort. As shown, with the valve 5 in its neutral position, there is a free flow of liquid from the pump back to the reservoir through the passage 33 as well as through the valve 5. On rotation of the shaft 4, the valve 5 moves away from its neutral position to supply pressure liquid to one side of the motor piston 3 and exhaust it from its other side, pressure then builds up in the line 26 which reduces, and may even overcome, the velocity head through the venturi so that pressure is transmitted through the passages 41 in the piston 37 to move the piston 37 rightwardly to close the passage 33 and so allow full pump pressure to be transmitted to move the motor piston 3. Specification 740,738 is referred to.

Abstract: 775,928. Centrifugal moulding of tyres. CONTINENTAL GUMMI-WERKE AKT.- GES. April 20, 1955 [April 24, 1954], No. 11350/55. Class 87(2). [Also in Group XXXIV] A method of making tyres, especially from polyamids or polyurethanes, by centrifugal casting includes the steps of placing reinforcement about a mandrel, placing bead rings near the margins of the reinforcement, folding the edges of the reinforcement about the bead rings and holding the free ends of the reinforcement in anchored position throughout the subsequent centrifugal casting operation. An annular mandrel 1 with reinforcement attached is bolted to a disc-shaped support 11 with a central boss 12 bored to fit over a pin 13 projecting from the inner face of a mould half 8. The support carrying the mandrel is held in place by a nut 14 screwed on a threaded end of the pin and the complementary mould half 8a is secured in correct relationship in known manner. The mould is rotated by a motor 9 while material, e.g. polyamide or polyurethane, is poured through the opening 15 and by centrifugal force, fills the space between the mandrel and the inner surface of the mould cavity until the required tyre section has been built up. Rotation is continued until the material has solidified. There may be a short heat treatment to assist polymerization. The mandrel is taken out, and the tyre removed, to assist which the mandrel may be collapsable. To maintain the reinforcement 2 firmly on the mandrel it is folded round bead rings 3 and the free edges are anchored in one of various ways described in the Specification. In Fig. 1, wires or threads 4 are looped back and forth through transverse holes 5 in the mandrel and drawn through the reinforcement by a needle. The holes 5 are circumferentially spaced on two radii, forming inner and outer rows. The inner row may be positioned to bring the inner transverse thread portions under the bead rings, and the holes are preferably staggered circumferentially as between the rows so that the threading may proceed in the manner of a lacing. In Fig. 2 the edges of the reinforcement are carried to the outer circumference of the mandrel and held down by a stretched elastic strip 6, the bead rings being held down by transverse pins 7. The bead rings 3 may be separately held by threads passing through an additional pair of rows of transverse holes. Adhesive may be used to hold the reinforcement on the mandrel.
