Patent GB-886728-A (GB)
Abstract: 886,728. Gyroscopic apparatus. AIR EQUIPMENT. April 1, 1958 [April 3, 1957], No. 10389/58. Class 97(3). A free gyroscope is adjusted to bring it into a reference position by causing the rotor to precess about the axis of the inner gimbal by exerting a torque on the outer gimbal the torque being produced by electromagnetic force acting directly on the gimbal. As shown, a three phase A.C. supply A and a D.C. supply B are switched on simultaneously to energize rotor motor 4, the heaters of normally closed bi-metallic strip time delay relays 13, 15, electromagnet 8 and relay 14. Roller 6 is moved by electromagnet 8 against cam 5 to turn the outer non-ferromagnetic gimbal 2 into its caged position in which the roller enters a notch in the cam. Thereafter, the contacts of relay 15 open, electromagnet 8 is de-energized (and roller 6 is retracted by spring 7) and the contacts of relay 14 are allowed to close to connect one terminal of electromagnets 10a, 10b to the D.C. supply B. Electromagnets 10a, 10b are mounted on fixed support 1 on opposite sides of the pivotal axis X-X of gimbal 2 (Fig. 1, not shown) and cooperate with two similarly arranged magnetic inserts so as to twist gimbal 2 in opposite directions about the axis X-X and thus to make the rotor precess in either direction without disturbing the gimbal. The relative strengths of the fields of the coils of relay 17 determine which magnet 10a or 10b is to, be energized by the relay and the current for these coils is controlled by potentiometer 11 having a resistance 11a fixed to gimbal 2 and a slide 11b fixed to a trunnion of casing 3. The magnet 10a or 10b which is energized by relay 17 is thus the one appropriate to bring the slide 11b into the central position and open the contacts of relay 17. When a further period allowed for this step has elapsed, relay 13 opens its contacts to energize relay 16 and make potentiometer 11 available for any other desired function by means of connections U.

Title: Metal wire spacer for use in the bundling of nested stacks of metal pieces
Inventor: LEGLER STEVE
IPC: B65D71/04
Filed: 1989-02-01
Abstract: Nested galvanized metal angle pieces 13 having a nestable profile arranged in at least two side-by-side stacks are separated one from another by preformed metal wire spacers provided with a corrosive resistant coating, e.g. galvanised and formed with a zig-zag profile corresponding to the cross-section of at least part of the profile of two of the angle pieces when positioned in side-by side relationship. The wire forming this spacer 10 has a circular cross-section to provide reduced contact with the surface of opposed nested ones of the pieces when positioned therebetween and to provide air flow and minimum water retention between the nested material pieces to substantially reduce the formation of white rust. <IMAGE>

Title: Integral series of screws
Inventor: STOLL KURT
IPC: F16B27/00
Filed: 1989-02-14
Abstract: In an arrangement with screws each has a shank whose head at one end thereof has an engagement part for a screw drive tool. The head has an end surface facing away from the shank and a peripheral surface between the end surface and the shank. The screws are formed into a row with identical orientation in sequence and are assembled as an integral chain, screws adjacent to each other in the longitudinal direction of the chain being formed together by an intentionally frangible means having a reduced material cross section. The frangible means is located on one screw of at least a pair of screws which are respectively formed together on the respective screw head adjacent to or at the edge of a tool engagement part (16) between the end surface (5) and the peripheral surface (6), and on the other screw of the pair on the end part of the shank (3) opposite the head (4). Screws 1 are joined together integraliy to form a continuous strip 2 or 2' either head-to-tip as shown in Figure 1 or side-by-side as shown in Figure 3; in either case the screws 1 are joined by shearable webs 14 located on the side of each screw head 4. In Figure 1, the webs 14 are at the junction between the end surface 5 and the peripheral surface 6 of the screw head; in Figure 3 the webs 14 are at the junction between the peripheral surface 6 and the screw shank 3. Either junction may be provided with a rim on which the webs 14 are formed. The screw strip 2' may be straight or coiled with the screws parallel to the axis of the coil. <IMAGE>

Title: Fast/slow motion video signal processing
Inventor: DORRICOTT MARTIN REX
IPC: H04N5/926
Filed: 1992-01-31
Abstract: A method of processing an input digital video signal enables display of the video image in fast or slow motion at a predetermined field or frame display rate. Output fields or frames are produced from the input fields or frames, at least some of the output fields or frames being produced by motion compensated temporal interpolation. The ratio of the number of output fields or frames to input fields or frames corresponding to a given portion of the image is set in dependence upon the desired increase or decrease in the motion rate of the image when displayed at the predetermined display rate. Interlaced fields are first convened to progressive scan, Fig 4b, after which the appropriate number of intermediate fields are interpolated, Fig 4c, and finally the interpolated fields are read out at the same rate as the input signal. Preferably all output fields are derived by interpolation (Fig 5(c)).   <IMAGE>

Title: Detecting defects on covered metal components
Inventor: FLORA JOHN H
IPC: G01N27/90
Filed: 1993-10-28
Abstract: Defects such as corrosion on the exterior of a component such as a metal pipe, tank, vessel or support structure which is insulated by a coating or cover, are detected by a low frequency eddy current system. A magnetising yoke 11 in the shape of an inverted U wound with an excitation coil 20 is placed on the cover insulating a metal component. Alternating current supplied to coil 20 produces an alternating magnetic field which induces an eddy current which runs through the metal component between the legs of the yoke. A pair of magnetic flux sensors 30 are used in differential connection to detect changes in the magnitude, phase or direction of the eddy current and the alternating magnetic field. Several excitation coils 20 which can be articulated can be used to conform to various pipe diameters. In addition, an absolute signal response can be obtained from one of the receiver coils. Defects located on the surface of pipes or tanks covered with marine growth can be detected using the probe with either a single pair of magnetic flux sensors 30 located beneath the excitation coil 20 or a plurality of magnetic flux sensor pairs differentially connected. <IMAGE>
