Patent GB-2058394-A (GB)
Title: Pressure-sensitive Optical Fibre Cable
IPC: G01G3/12
Filed: 1980-08-22
Abstract: An optical fibre cable suitable for pressure sensing, for example for detecting the passage of a moving vehicle and its speed or weight, comprises one or more optical fibre modules each consisting of a vitreous optical fibre coated with a resilient buffering layer of polymeric material such as silicone resin, and possibly an additional buffering layer of nylon or polyester, one or more strands of deformable filamentary material laid straight along or helically wound around the buffered fibre, and a protective sleeve of abrasion-resistant material extruded over the winding. Pressure applied to the cable deforms the sleeve and is transmitted locally by the winding to the fibre, causing attenuation of light propagated along the fibre to sensing means. The winding may consist of aromatic polyamide yarns, glass filaments, nylon filaments or cord, or fine copper wire. The sleeve may be of polyester, polyethylene, polyvinyl chloride, or natural or synthetic rubber. The module or cable may have an outer polyethylene jacket.

Title: Improvements relating to the Measurement of the Ventilation of Smoking Articles
IPC: G01F15/075
Filed: 1980-10-06
Abstract: Apparatus and method for measuring a quantity of air entering a cigarette 2 utilise a housing 1 bounding a sealed annular space around the cigarette or a part thereof, a duct 6, communicating with the said space, through which air can pass thereto and a heat-effect anemometer, for example of thermistor type, including a probe disposed within the duct. For measuring the quantity of ventilation air entering the cigarette, the annular space, surrounding the rod except for the burning coal, may be formed by an outer sleeve member displaceable axially over an inner member. For measuring also the quantity of air entering a filter tip of the cigarette, another sealed space, surrounding a length of the tip, may be formed in the inner member. For measuring also the air supplied to the burning coal, the housing may bound a further sealed annular space, which encloses the coal. <IMAGE>

Title: Bending test for flexi-rigid printed circuit boards
IPC: G01N3/00
Filed: 1981-05-05
Abstract: Rigid portions of a flexi-rigid circuit board are secured to a fixed table 12 and a movable table 13 in order to test the board under bending. The movable table 13 is rotatable through +/-180 DEG  on pivots 19, 20 passing through vertically movable plates (21, 22). In order that the bending is uniform throughout this range rotation of the table 13 causes a vertical movement of the plate carrying the pivot 20, so that the displacement of the portion mounted on table 13 is proportional to the angle made by the table. The vertical movement of the pivot may be effected by a cam as shown, or by a system of cranks (Figure 13, not shown). To apply a repetitive bending action the spindle may be driven by an electric motor through a crank and reciprocating rack (Figure 14 not shown), to which the camming surface may be attached (Figure 18) and the number of bending cycles counted until a monitoring system detects a break in the continuity of the printed circuit in the board. <IMAGE>

Title: A method of reducing the power consumption of the stepping motor of an electronic timepiece
IPC: H02P8/02
Filed: 1981-08-21
Abstract: The present invention comprises measuring, upon application of a drive pulse to the actuating coil 5 of the stepping motor, the variation in the magnetic induction flux in the stator of the motor, and interrupting the drive pulse when the variation in flux reaches a predetermined value. Measurement of the variation in flux may be effected, for example, by detecting the current in the actuating coil and integrating the difference between the supply voltage of the actuating coil and the product of the current by the d.c. resistance of the coil, or by providing an auxiliary detection coil 71 and integrating the voltage induced therein in an integrator 73, 74. When the integrator outputs exceeds the magnitude of either a positive or negative reference voltage, a comparator circuit 78, 79, 81 provides the signal to a circuit 13 to terminate the drive pulse. The foregoing abstract is not to be taken as limiting the invention described herein, and in order to understand the full nature and extent of the technical disclosure herein, reference should be made to the accompanying drawings and detailed description.

Title: Method of making radioactive sources
Inventor: HADDEN DR R J B
IPC: G21G4/00
Filed: 1983-04-20
Abstract: In the manufacture of radioactive sources, a compromise is reached between radioactive emission efficiency and physical containment of the radionuclide in the surface of a substrate. The method of the invention involves directing a laser beam at the substrate so as to cause the surface to melt locally and absorb an adjacent radioactive material thereon, and then removing the laser beam to effect rapid cooling and solidification. The substrate is preferably of metal, and may be caused to solidify in a micro- crystalline or amorphous state. Examples include americium-241, iron-55 and nickel-63 on stainless steel and copper substrates.

Title: Fishing float
Inventor: LANGLEY PETER G
IPC: A01K93/00
Filed: 1984-01-12
Abstract: A fishing float (20) comprises a tubular top portion (25) open at its upper end (26) and being provided with an aperture (27) in its side wall through which water can flow into and out of the tubular portion, the aperture being spaced below said open upper end. In use of the float, when the aperture is at or below the water level, such as when the float has been pulled down to such a depth by a fish, water can pass freely into and out of the tubular portion. As the float is pulled deeper, water is displaced in an amount proportional only to the cross sectional area of the side wall of the tubular portion rather than the entire cross-sectional area of the tubular portion (including its internal bore) since water enters into the bore of the tubular portion. Hence the rate of increase of the upward force, exerted by water on the float as the float is pulled deeper, is low. Despite this the top portion of the float presents a large visible area to an angler using it and is not significantly affected by wind above the water surface. <IMAGE>
