Patent GB-2067283-A (GB)
Title: Determining relative movement
IPC: G01D5/26
Filed: 1981-01-08
Abstract: A device for determining relative movement has a scale 6, and a reading means 7 with reading elements 10 spaced along the scale 6 by increments less than the spacing between adjacent markers 8, the reading elements 10 being also spaced from each other in a direction transverse to the scale 6 whereby in particular the device may be used to determine increments which are small relative to the dimensions of the reading elements 10. A scaling apparatus for use with a drawing board has two such devices, the scale of the second device being carried on a cursor of the first device, and the readings of the two cursors being indicated on a display which may incorporate a conversion factor. <IMAGE>
Patent GB-2079946-A (GB)
Title: NMR Imaging Method
IPC: G01R33/54
Filed: 1981-03-13
Abstract: To produce image information from an object it is subjected to a continuous static magnetic field along a Z axis and to sets of sequences of orthogonal magnetic field gradients Gx, Gy and Gz. Spins in a selected plane X-Z are excited by rf pulses and an associated Gy gradient. The selected spins are subjected to all three gradients of which the Gz gradient provides twist or warp to each column of spins extending along the Z axis to phase-encode the columns. The Gx gradient is reversed and held constant whilst spin-echo signals are read out. In each set of sequences a different value of Gz gradient is employed. The Fourier transformed spin-echo signals obtained from each sequence, when arranged in order of increasing Gz gradient and subjected to a second Fourier transform, represent the distribution of spin density in the Z direction, giving a two-dimensional image of the selected Z plane. <IMAGE>

Title: Control means for controlling the drive torque of a motor
IPC: B66B1/06
Filed: 1981-04-09
Abstract: With this start-up control apparatus it is intended to reduce the starting jerk at elevators resulting from superimposing the motor cut-on moment and load moment and to improve the starting comfort of the elevator passengers. The brake magnet of the electromechanical holding brake of the elevator is connected for this purpose with a regulation device, by means of which there can be linearly decreasingly controlled the braking force during the elevator's start-up, so that there can be obtained a linearly ascending start-up moment of the drive. The linear decrease of the braking force first appears following decay of the cut-on moment peak of the drive motor. This can be obtained by optimum correlation of the start-up time point of a reference value transmitter of the regulation device and the drive motor as well as the proportional part (P-part) of the reference value transmitter, whose transfer function approximately corresponds to the time behavior of a PI-regulator. The cut-on moment peak can only have an inappreciable effect, since the brake spring is dimensioned such that the mechanical brake moment amounts to 3-fold to 3.5-fold of the motor rated moment or torque.

Filed: 1982-04-16
Abstract: A continuously cast strand (16) is withdrawn from mould (14) in a stepwise manner, and the solidifying metal in the mould being subjected to a super pressure between such steps. On completion of a withdrawal cycle, molten metal (2) is fed from the supply (1) through a feed duct (8) into an auxiliary vessel (18) prefilled with an inert gas, whereupon a preset pressure is built up in the molten metal (2) inside the vessel (18) and in the solidifying strand (16) in the mould. The molten metal (2) is then caused to reciprocate between the vessel (18) and the duct (8) so varying the pressure at the solidifying skin of the strand. During strand withdrawal the molten metal 2 is fed into the mould (14) from the vessel 18 and/or the supply (1). The invention is well adapted to casting of light aluminium- and magnesium-base metals and alloys. <IMAGE>

Title: Electrohydraulic displacing device
Inventor: HENRICH KURT
IPC: F15B15/18
Filed: 1983-02-03
Abstract: The device comprises a housing (18), an electric drive motor (36), and a pump (21) to pump an operating liquid which acts on a setting piston (31) guided in a cylinder (17). Present between the cylinder (17) and the housing (18) is an annular chamber (29) for the liquid, this chamber being connected through a passage (26) with the cylinder bore (30). When the device is vertical, an air space lies above the liquid; to avoid mixing of air with the liquid during each flow phase and thus avoid a reduction in the displacing force of the device, the housing (18) is parallelepipedonal and the passage (26) has a step (37) in one housing side wall (38) bounded by a curved guide surface (25) so that liquid enters the bore (30) below the liquid surface (12). A partition (14) with a bore (13) is provided, for the formation of a compensating volume, between the housing (18) and the cylinder (17), when the device is used horizontally. <IMAGE>

Title: Silo for bulk material
Inventor: BUCHFINK ADOLF
IPC: B01F33/40
Filed: 1983-05-17
Abstract: The silo comprises a mixing chamber (3) on the silo base (2) and a discharge channel (4) between the mixing chamber (3) and the outer wall of the silo, through which the mixed bulk material is evacuated from the silo is provided with a partition wall (5) between the mixing chamber (3) and the channel (4) in which is formed an overflow opening (8), beneath the mixing chamber roof, through which mixed bulk material reaches the discharge channel (4) and thereafter the discharge outlet (12). In normal operation a direct connection from the silo zone to the outlet channel is thus precluded, so that more thorough mixing of the material in the mixing zone is assured. <IMAGE>

Title: Safety closure for a container
Inventor: SPIELHOFF PETER
IPC: B65D55/12
Filed: 1983-09-02
Abstract: A safety closure far a container (1) having a locking surface on a part (4) carried by the container, comprises a closure cap (5, 6, 7) surrounded by an auxiliary cap part (15). To release the closure cap the cap part (15) is moved towards the container so wedge surfaces (12, 16) drive hooks (4) radially inwardly to release from the locking surface. Grip projections provided on cylindrical part 5 and extending through apertures in auxiliary part 15 can be pressed inwardly to maintain the hooks (4) clear of the locking surfaces to allow the closure cap and cap part assembly (5, 6, 7, 15) to be lifted off the container. Re-engagement is effected by automatic snap-action when the assembly (5, 6, 7, 15) is replaced on the container. <IMAGE>
Patent GB-2132036-A (GB)
Title: Connecting device
Inventor: MCGAFFIGAN THOMAS HAYNES
IPC: H01R13/193
Filed: 1983-10-20
Abstract: A reusable heat-recoverable connecting device (20) has an annular driver member (22) and a circumferentially split annular spring biasing means (24) inside and generally concentric with the driver member (22). The spring biasing means (24) exerts an outward radial force against the inside surface of the driver member (22). The driver member is made from a heat-recoverable metal having a martensitic state and an austenitic state. The driver member (22) is expanded radially outward by the spring biasing means (24) when the driver member (22) is in its martensitic state to facilitate insertion of a substrate. The driver member (22) recovers to its non-expanded dimension when it returns to its austenitic state to cause engagement between the spring biasing means (24) and the inserted substrate.

Title: Device for changing the orientation of sheet material moved along a conveyor path
Inventor: LEHMANN GUNTHART
IPC: B65H5/12
Filed: 1984-04-18
Abstract: A device for changing the orientation of a piece of sheet material (1) moved along a conveyor path (3) comprises movable grippers (15) guided by a driven device along a closed orbital path (16), actuatable between clamped and released conditions to grasp and release the piece of sheet material (1). As each conveyed piece of sheet material (1) reaches the starting point of an intended-turning portion (18) of the orbital path, the gripper clamps the fed piece (1) and transports it to the end of the path portion (18). A rotating device acting on the grippers makes it possible, during traverse of the path portion (18), to produce an incremental rotary displacement of each gripper (15), superimposed on its orbital movement, so as to rotate the clamped piece (1) through a desired angle. At the end of the path portion (18), each gripper (15) is restored to its release position, thus releasing the piece (1) in its turned orientation (9).   <IMAGE>
