Title: Steering system for a vehicle having two sections pivotally connected about a vertical steering axis
IPC: B62D53/02
Filed: 1961-09-29
Abstract: 928,021. Steering articulated vehicles. GENERAL MOTORS CORPORATION. Sept. 29, 1961 [Oct. 6, 1960], No. 35160/61. Classes 79(3) and 79(5) In a scraper vehicle comprising a twowheeled tractor 2 connected by a pivot 12 to a scraper bowl 22 and steered by a doubleacting hydraulic jack 32 which rotates the tractor 2 about the pivot 12, the piston rod 38 of the jack 32 is connected to a control link 48 coupled to the scraper bowl and to a steering link 44 coupled to the tractor 2, the links 44, 48 being arranged such that a given jack extension produces constant rotation of the tractor 2 throughout 180 degrees of steering movement. To ensure that the jack 32 provides equal effort during extension and retraction the piston rod 38 has one half of the cross-sectional area of the piston 36 and hydraulic fluid is supplied to both sides of the piston during extension. To extend the jack, fluid is supplied by a manual selector valve 58 (Fig. 6) through a conduit 54 to a chamber 62 communicating via a conduit 72 with the part of the cylinder 34 remote from the piston rod 38. A spring-loaded valve 60 opened by the pressure in the chamber 62 supplies fluid to the other side of the piston via conduits 78, 76. To retract the jack, fluid is supplied by the selector valve 58 through a conduit 56, a chamber 64, a non-return valve 74 and the conduit 76 to the cylinder 34. A check valve 88 in the piston 36 permits retraction of the jack under compressive shock loads and a relief valve 82 permits extension under tensile shock loads, make-up fluid being delivered to the cylinder through a check valve 86 and the conduit 72. The tractor 2 has a main frame 4 connected by a horizontal pivot to a member 6 connected by the pivot 12 to frame members 14, 16 attached by a torque tube 18 and arms 20 to the scraper bowl 22. The height of the scraper bowl and its apron is controlled by a hydraulic jack mechanism 28.

Title: Mechanism in rolling mills for rolll reduction of tubes
IPC: B21B19/06
Filed: 1970-07-21
Abstract: 1308382 Rolling tubes DEUTSCHE EDELSTAHLWERKE AG 21 July 1970 [5 Aug 1969] 35326/70 Heading B3M In a tube rolling mill, in which shouldered rolls 1 reduce a tube 3 supported by a mandrel 2, the rolls can be rapidly withdrawn from the tube by their screw adjusting spindles 6 when a bulge develops in a tube. Such a bulge is to occur at the trailing end of a tube if the ratio of diameter to wall thickness is greater than 10 to 1. A photo-cell 18 detects a bulge and causes withdrawal of the rolls, after a predetermined time delay. After a further time delay movement of the rolls is stopped. The rolls can be rapidly withdrawn either by the normal screwdown motor 8, which for this application is provided with a supplementary high-speed gear or variable transmission, or by the use of a further motor 15. The motor 15 can be coupled by a clutch 17 to the screws 6, following uncoupling of the motor 8 by a clutch 10. A limit switch 20 may be used for stopping withdrawal of the rolls after they have moved a given (adjustable) distance from the tube.

Title: Improvements in and relating to springs for doors, gates and like pivoted members
IPC: E05F1/10
Filed: 1932-12-28
Abstract: 411,944. Door - operating springs ; door stops. STEVENS, H. A., 155, Belsize Road, Kilburn, London. Dec. 28, 1932, No. 36695. [Class 65 (i).] An operating spring for doors and the like, of the kind comprising a length of spring strip secured at its ends to the door and door frame so that it bends and moves bodily in a plane substantially at right angles to the pivotal axis of the door, has the securing means of at least one end angularly adjustable to regulate the effect of the spring. The spring may be of various forms, to suit the action required, and may be reinforced along part of its length by a second strip secured to it, producing a laminated construction. For doors opening both ways a spring may be provided on each side of the door, or a spring of spiral form may be used. In the form shown the spring strip 13, with reinforcing strip 19, is fixed at one end to an upwardly-projecting peg fitting in a socket 16 on a bracket on the door frame and at the other end to a downwardly-projecting peg 21 engaging a similar socket on the door ; both pegs are rotatable in their sockets, and can be locked in any position by set screws, which may engage recesses in the pegs. In a modification, the pegs may be screw-threaded and secured by nuts to the fixing brackets, in the required positions. In a further modification, a setscrew carried by one of the pegs may move in a circumferential slot in the bracket, so that the end of the spring is allowed some angular motion. In the case of a spiral spring, the inner end of the spring may be mounted freely on a vertical pin carried by one of the brackets. The peg 21 at the door end of the spring may be arranged to engage a resiliently mounted plunger 27 on the door frame to buffer the closing of the door ; the bracket carrying the plunger may also have a pair of spring arms, as shown, to embrace the peg and prevent rattling.

Filed: 1974-08-21
Abstract: 1477508 Measuring apparatus RANK ORGANISATION Ltd 21 Aug 1975 [21 Aug 1974] 36725/74 Headings G1M and G1N A measuring instrument comprises a workpiece supporting table 2 and a pick-up 6 in the form of a transducer carried on a pick-up mount, e.g. an arm 8, the arrangement being such that the table 2 and the pick-up 6 are relatively rotatable about a fixed axis and also the pick-up mount is adjustable to move the pick-up 6 radially with respect to the fixed axis. A displacement transducer 24 sensitive to the radial movement of the pick-up mount during adjustment is provided and is operative to produce an output signal representative of radial displacements of the pick-up. As shown the arm 8 is adjustably mounted in bearings 17 of a carriage 12, the last mentioned being supported adjustably by a column 3. The transducer 24 is mounted in the carriage and comprises a linear displacement grating transducer having a grating 25 mounted on a frame 26 which runs between two linear roller bearing slides 27. The grating 25 is acted on by an anvil 23 which is operatively connected to an adjustable stop 20 of the arm 8 by magnetic forces. Alternatively the transducer may comprise a linear displacement capacitive or inductive transducer. The output signal of the displacement transducer. may be displayed on an adjustable datum display device. Means are provided for producing an output representing the sum of the signals from the pick-up and the displacement transducer. The pick-up is adjustable for engagement with the outer wall of a body, Figs. 1, 3, (not shown) or the inner wall of a hollow body, Figs. 2, 4, (not shown). In the former case the stylus of the pick-up is horizontally orientated and the arm 8 is mounted in a pair of bearings different from those mentioned above, Fig. 3 (not shown). The instrument may be used to find the radius of a component by first centring a reference body on the table and bringing the pickup into engagement therewith and then repeating the process with the component, the radius of the reference body together with the transducer difference reading giving the radius of the component. The diameter of an uncentred body on the table or the length of a body on the table can be measured by bringing the pick-up into engagement with diametrically opposed positions of the uncentred body or the ends of the second mentioned body and calculating electronically the dimension required by the"least squares circle."
