Patent GB-2021053-A (GB)
Title: Vehicle-stabilising system.
IPC: B60G21/055
Filed: 1979-04-20
Abstract: A vehicle-stabilising system comprises a stabiliser having arms associated with respective sides of a sprung vehicle axle and connected by a torsion bar having a response characteristic which, starting from a mean spring position, hardens progressively with approach to extreme spring positions. In such a system, the connection between the two arms 11, 12 comprises at least one torsion element whose torsional rigidity is less than that of the said bar and whose angle of turning is limited. A said torsion element may be provided in the connection of at least one arm to the torsion bar or interposed between parts into which the bar is divided, suitably at its mid length. The torsion element may comprise two inter- engaging bushes 6, 19 connected by way of a torsionally elastic intermediate layer 17, the angle of turning being limited by a distance 23 between a system of teeth 20, 24 provided in the region of an end face of the element. The system allows the torsion bar to be brought into play only after an initial torque is taken up by the last motion between the teeth 20, 24. <IMAGE>

Filed: 1979-07-09
Abstract: Sign-making materials are described which consist of two sheets held together via intermediate layers and peelable apart. Adjacent a transparent or translucent one of the sheets is a layer of adhesive, and between this layer and the other sheet is an imaging layer which after imagewise exposure, shears along the edges of the images when the sheets are peeled apart. The image-forming layer may be made of a pigmented non-photosensitive layer and an unpigmented photosensitive layer. The adhesive layer may be of permanently tacky pressure-sensitive adhesive.

Patent GB-2028523-A (GB)
Title: Recording surface characteristics
IPC: A61B5/117
Filed: 1979-07-27
Abstract: The recording of surface topology e.g. of fingerprints is obtained by first bringing the surface into contact with the imaging material-coated side of a dry process dispersion type recording film of the type disclosed in specification 1402760. Radiant energy is then momentarily directed to the imaging material through the transparent substrate. It was discovered that when the surface has projections (14b, 14c etc) and/or depressions (14e, 14f etc), (for example, like that found on the surface of animal or plant tissue such as skin), at least the projecting portions thereof act as high resolution heat sinks so that heavily heat-sinked points 11 remain opaque and points (11a, 11b etc) unengaged by the surface become relatively transparent, to provide a high resolution picture. In a machine for effecting the process, pressure of a finger on quartz block 32 causes flash lamps 34 to be energised and the exposed film then passes to the viewing station. <IMAGE>

Title: Improvements in Textile Finishing
IPC: D06P3/14
Filed: 1979-08-08
Abstract: A method of treating textile articles with finishing agents which require to be applied at a pH value below that at which the agents react comprises adding to the treatment bath at the commencement of treatment an acid which decomposes or volatilises at the temperature of the reaction stage. The process is suitable for applying dyestuffs, e.g. reactive dyes, or shrink-proofing compositions to wool articles. The process may be started at a relatively low temperature and the temperature of the dyebath is progressively raised to the boil at a controlled rate and is then maintained at the boil for a time sufficient to complete fixation of the dye. A suitable acid for use in the process is trifluoroacetic acid.
Patent GB-2057364-A (GB)
Title: Buoys for use with sea currents
IPC: B63B22/18
Filed: 1979-08-30
Abstract: A float 22 supports a string of drogues 25, 26 and 27 and a sinker 28. The drogues are acted upon by sea currents at their respective depths. Alternatively one long drogue is used for the entire depth. The net result is that the effect of currents at different depths is integrated; while not giving precise scientific data about current at any particular depth, such integration of current over depth can have two practical uses. One use is to provide a measure of the effect of current of a large floating body, such as an iceberg, in order to estimate the effects of other forces (e.g. towing or wind) or the body. The other use envisaged is to provide a buoy which is substantially stationary over the sea bed in spite of sea currents. In this case a vector triangle must be devised so that currents at different depths cancel. <IMAGE>
Patent GB-2057896-A (GB)
Title: Walking aids
IPC: A61H3/04
Filed: 1979-09-13
Abstract: The aid comprises side membera (10, 12) and a frame (16, 18) having three horizontal bars (20, 22, 24) extending therebetween, downward movement of any of which will produce braking of the aid. The bars (20, 22, 24) act on vertically slidable rods (30) and a braking pad or shoe (32) is situated at the lower end of each rod. A spring (48) urges the rod upwardly so that the aid is normally free to be moved backwards or forwards. Downward movement of one of the bars acts on the rod (30) through a collar (40, 42) and, against the spring (48), urges the shoe (32) into braking engagement with the floor. Means are provided for inhibiting the braking produced by downward movement of some of the bars, and for locking the wheels or castors so that they point in one direction only. <IMAGE>

Title: A Method of Setting the Position of a Loosely Carried Sleeve in a Rolling Mill
IPC: B21B13/14
Filed: 1981-01-27
Abstract: The method of the invention is applied to a rolling mill having a backing roll (3) carrying a sleeve loosely (4) on the barrel. The sleeve (4) is axially movable relative to the roll and by being given a slight inclination by the application of radially inward forces at two spaced positions (22,23) on the outer peripheral surface of the sleeve relative to the axial direction. The points (22,23) at which these forces are applied allow rotation of the sleeve in either direction. Through control of the relative values of the two forces, the mill has a powerful crown controlling capacity for work-pieces of various widths. <IMAGE>

Title: A unidirectional coupling for the drive of a sequential display unit
Inventor: BEAUCHAMP FREDERICK CHARLES
IPC: F16D41/22
Filed: 1981-10-07
Abstract: A unidirectional coupling for transmitting rotational movement in one direction from a driving member (53) to a driven member (55) rotatable about the same axis is described in which the driving member (53), a belt drive pulley, is mounted so as to be rotatable and axially displaceable relative to the driven member (55). The driving member when rotated in one direction adopts one axial position as shown in which it is freely rotatable relative to the driven member, and displacement means comprising a helical groove (64) and a dog (63) are provided for axially displacing the driving member (53) upon rotation thereof to another axial position in which cooperating engagement means in the form of pins (66 and 67) on the driving and driven member communicate the rotation of the driving member to the driven member. Two such couplings are used in a sequential display unit to allow reversal of the drive whilst maintaining the necessary tension in a display strip. <IMAGE>

Abstract: In a fluid-filled machine such as a motor, a throughgoing shaft 12 is provided with a housing 14 and an annular spring loaded piston 34 surrounding the shaft 12 and sealed thereto and to the housing via lip seals 30, 38. The piston 34 forms the movable wall of a variable volume chamber which is sealed by the lip seals 30, 38 when the shaft is stationary but which is placed in communication with the chamber 43 containing the spring 42 when the shaft rotates by the seals 30, 38 becoming inoperative due to centrifugal force acting thereon. Pressure in the variable volume chamber, when the shaft 12 is stationary, ensures integrity of the seal and pressure and temperature variations are accommodated by piston movement.

Title: Pirani gauges
Inventor: HOLME ALAN EDWARD
IPC: G01L21/12
Filed: 1982-08-26
Abstract: In a circuit for controlling the temperature of a filament F in a Pirani gauge head, secondary temperature compensation is provided by mounting an auxiliary resistor T2 adjacent the temperature-compensating arm T1 of the bridge circuit 6. The resistor T2 forms part of a potential divider which provides a preset offset voltage to an associated output amplifier 10. This offset voltage is added algebraically to the variable voltage driving the bridge circuit 6 so as to provide additional temperature compensation. The measured value is thus accurate over the whole of the operating range instead of at just one point. <IMAGE>
