Patent GB-2014507-A (GB)
Title: Detergent bars having curved surface stripes
IPC: C11D13/18
Filed: 1979-02-19
Abstract: The application of torque downstream of the extrusion die to a striped extruded detergent column provides, after cutting into billets which are then stamped, bars with a spiral striping. The present invention proposes reversal of torque so that a sinusoidal striping is present on the bar. The reversal may be continuous, or interrupted to produce spiral striping interrupted by striping parallel to the column axis. The bar may comprise at least a quarter, half or one cycle of a sinusoidal striping along the bar length. The stamping may be longitudinal, or skew to the column axis. <IMAGE>

Title: Apparatus for the Automatic Balancing of the Ram and Upper Part of the Tool of a Press Using Compressed Air Cylinders
IPC: B30B15/00
Filed: 1979-04-26
Abstract: Apparatus for the automatic counter-balancing of the ram 3 and upper part of the tool of a press uses compressed air cylinders 19. If imbalance occurs after a tool is changed, a lever 1 pivotally mounted at 2 on the ram 3 actuates a control member 5 or 6 which results in the actuation of an outlet or inlet valve 8 or 7. The pressure prevailing in the compressed air cylinders 19 is increased or reduced by the outlet and inlet valves until balancing is achieved. A servo motor 24 with a gear unit 25 and contact pressure gauge 26 are interposed between the control members 5 and 6 and the outlet and inlet valves 8 and 7. <IMAGE>

Patent GB-2034888-A (GB)
Title: Method and apparatus for determining a granularity property of a subsurface formation around a borehole
IPC: G01N29/11
Filed: 1979-10-30
Abstract: In broad band high frequency acoustic investigation of a subsurface formation around a borehole, like pulses containing a range of acoustic frequencies selected to produce detectable acoustic backscatter from a broad range of grain sizes are transmitted into the subsurface formation and the acoustic backscatter is detected and a spectrum thereof produced and averaged over adjacent subsurface formation regions. A subsurface formation parameter such as the frequency dependency of the attenuation of the backscatter is determined from an analysis of the spectrum to provide an indication of a granularity property of the subsurface formation. In another technique the spectrum of the detected backscatter is modified to remove the effect of the frequency response of the system with which the investigation is made. The modified spectrum may then be used to derive an indication of the granularity property of the subsurface earth formation such as its mean grain size or grain size distribution.

Patent GB-2080689-A (GB)
Title: Sterilising fitments for injection devices
IPC: A61M5/00
Filed: 1981-06-02
Abstract: In order to minimise the risk of infection when a large number of animals are injected with the same needle 3, the injecting gun 1 is provided with a stainless steel sleeve 9 which surrounds the needle 3. The sleeve 9 comprises a first tube 10 attached to the needle connecting body 2 and a second tube 11 telescopically slidable within the first tube 10 against a spring 22. A detachable plastics cap 12 incorporating a sterilizing substance and having a layer of felt 18 projecting therefrom is fitted on the free end of the second tube 11. In use of the gun 1 to inject an animal, the layer of felt 18 projecting from the cap 12 is brought into contact with the proposed site of injection and pressure is applied to the gun 1 to apply sterilizing substance to the animal's skin, and to cause the tubes 10, 11 to telescope, so that the point of the needle 3 passes through the sterilizing substance and punctures the skin of the animal. On releasing the applied pressure, the point of the needle 3 will be withdrawn from the animal and will pass back through the sterilizing substance under the action of the spring 22. A similar fitting may be used for marking an animal during injection, and such a fitting is applicable to a high pressure hypodermic gun. <IMAGE>

Patent GB-812662-A (GB)
Abstract: 812,662. Electromagnets. MINNEAPOLISHONEYWELL REGULATOR CO. Aug. 16, 1957 [Sept. 6, 1956 (2)], No. 25944/57. Class 35. [Also in Group XXXVIII] A torque-motor for gyroscopes comprises a set of arcuate coils mounted in a cylindrical surface passing between magnetic poles, the same rotor also carrying a device for sensing the amount of its movement from a neutral position. As shown in Fig. 2, the driving coils 60, 61 and 62, 63, position indicating coil 59, and a dummy coil 58 for balancing, are all embedded in the cylindrical rim 54 of a cup-shaped, moulded plastic rotor 52. These coils are connected to an external control circuit through flexible leads connected to insulated terminal pins 56. Flux across the active air-gaps 69 is provided by magnetic members 65, 66 either or both being permanently magnetic. The driving coils are all connected in series, coils 60 and 61 being in opposition and likewise coils 62 and 63. The direction of rotation of the cup thus depends on the polarity of current supplied to the driving coils, only those parts of the coils in the working gap being effective in producing torque. The position-signal generating device consists of E-shaped laminated magnetic cores 74, 78 on either side of the rotor rim, the core 78 carrying equally energized coils 85, 86. When the rotor is in its neutral position the fluxes across air-gaps 82, 84 induce balancing voltages in the two sides of the coil 59, but any deviation produces a signal output. In the modification shown in Figs. 5 and 7, driving coils 113, 114 and 115, 116 are secured to or moulded in rim segments 109, 110, the reduced middle sections of which are located in air-gaps 97 between a permanent magnet 91 and a laminated core-ring 90. Coils 121, 122 which are secured to the rotor lie in the air-gaps between pairs of legs 99, 100 on either side of the rotor and projecting, together with a middle pole 101, from the core-ring 90. Each of these legs carries an energizing coil 102, and any movement of the rotor coils produces a signal output as in Fig. 2.

Title: Testing device for radar systems and the like
Inventor: WARREN K A J
IPC: G01S7/40
Filed: 1982-07-28
Abstract: When existing radar systems fail to detect a target the operator may be unsure whether this is because of some failure in the apparatus or because there is in fact no target there. The invention deals with this problem by providing a testing device 15, 16, 17, 18 and 19 for simulating targets at different ranges. The testing device includes a small aerial 15 arranged to sample a transmitted pulse. This sample is fed to a circuit 19 which imposes successive delays on the sample and feeds it back to the aerial 15 at successive different times. The successive delays are produced by a delay line 21 and a feed-back loop containing an amplifier 25. The circuit 19 also includes a frequency shifter 24 which simulates a Doppler shift. <IMAGE>
