Patent GB-2194022-A (GB)
Title: Valve
Inventor: KELSEY CHRISTOPHER GEORGE
IPC: F16K5/04
Filed: 1987-08-12
Abstract: A fluid control valve has two cylinders 24, 26 arranged parallel to each other with their surfaces in contact. At least one of the cylinders has a groove formed in its surface extending partially around the circumference and varying in depth along its extent to define an aperture for fluid to flow through. This aperture can be varied in size by rotating the cylinders thereby controlling the flow rate of fluid through the valve. The cylinders are rotated in the same direction such that their contact surfaces move in opposite directions. This arrangement provides a wiping action to reduce the likelihood of jamming when the valve is operated. The cylinders are preferably rotated by three interengaging pinion gears driven by suitable drive means. <IMAGE>
Patent GB-2196547-A (GB)
Title: Mixing polymers such as rubber
Inventor: FREAKLEY PHILIP KENNETH
IPC: B29B7/00
Filed: 1987-09-01
Abstract: Consistent control of viscosity when mixing polymers, especially rubber, with additives is desirable. The process comprises deforming polymer until it is estimated to attain a predetermined viscosity, then adding oil or plasticiser, and deforming the resulting mixture until it is estimated to attain a predetermined viscosity. Our way of estimating that the predetermined viscosity is attained is as follows: the actual viscosity is compared with the predetermined viscosity, or with a target viscosity adjusted for time and/or temperature from the predetermined viscosity, and, during the same or a subsequent step of the process, adding oil, plasticiser or other viscosity-affecting chemical in a quantity determined by the comparison.

Patent GB-2215846-A (GB)
Title: Method and apparatus for measuring the type and concentration of ion species in liquids
Inventor: BOARD KENNETH
IPC: G01N33/18
Filed: 1988-03-23
Abstract: Ion species in a liquid are identified by placing two spaced apart electrodes in the liquid, applying a voltage between the electrodes which is greater than qNd<2>/2E where q=the charge on the electron, N is the highest ion concentration expected, d is the distance between electrodes and E is permittivity of the liquid. The interval(s) between the cessation of charging current due to capacitance between the electrodes and one or more subsequent falls in the current which then flows between the electrodes are measured to identify the ions. The magnitude of each fall is characteristic of the concentration of an ionic impurity in the water and the time at which the fall occurs indicates the type of ion. In an embodiment of the present invention, a cell based on a silicon substrate 25 has electrodes 30 to 33 carried on ridges in the substrate separated by grooves 26, 27 and 28. In operation, water to be analysed for ionic impurities fills the grooves. <IMAGE>

Patent GB-2221643-A (GB)
Title: Grids and other cellular panels
Inventor: COLEMAN JOHN
IPC: B29D28/00
Filed: 1988-08-11
Abstract: The panels, particularly for use as access platforms or walk-ways, are moulded from cold-cured phenolic resin which may include glass fibre reinforcement. A method of manufacturing such panels, eg a grid (10), uses a mould (12) shaped to define an open topped cavity complementary to the desired shape of grid, projections (14) of the mould corresponding to the dimensions of the grid apertures; the cavity being filled with the phenolic resin, curing agent and glass fibre or other reinforcement, if required, and the mix being allowed to cure in the mould before removal. Preferably at least the projections (14) of the mould are formed from plastics material eg low linear density polythene having greater thermal volume expansion than the mix during curing so that, on cooling, stripping from the mould is facilitated. A non-slip surface may be provided by rolling grit or the like (22) into the upper surface before curing of the latter has been completed. Cellular panels as defined also include panels having blind end pockets. <IMAGE>

Title: Anchoring blind rivets in soft material
Inventor: BRADLEY WILLIAM DAVID
IPC: F16B19/08
Filed: 1989-02-03
Abstract: A blind rivet, for anchoring in a blind hole in relatively soft material such as softwood, comprises a tubular shell (14) with a weakened thinner portion (19), and a stem (15) with an enlarged head (29) having a smooth underhead curve (32). The weakened portion (19) of the shell also has four longitudinal V-section weakening grooves (24) in its inner wall. The weakened portion (19) has a wall thickness which is less than that of the remainder (22) of the shell, the junction between the two parts presenting an internal annular shoulder (23). When tension is applied to the pulling portion (26) of the stem, the stem head (29) enters the weakened portion (19) and splits it apart along the grooves (24) to form legs which anchor in the soft material. The higher strength of the remainder (22) of the shell prevents the stem head (29) passing beyond the shoulder (23) before the stem fractures at the breakneck (27). <IMAGE>

Patent GB-894477-A (GB)
Abstract: 894,477. Measuring attenuation frequency or reflection/frequency characteristics of networks. ROHDE, L., and SCHWARZ, H., [trading as ROHDE & SCHWARZ]. May 13, 1960 [May 15, 1959], No. 16919/60. Class 37. The attenuation/frequency or reflection/frequency characteristic of a network 13 is measured by applying to it a signal from a swept frequency oscillator 1 frequency and pulse modulated respectively by sawtooth and pulse generators 3, 4, the output from the network under test being dependent on the width, repetition frequency or phase of the modulating pulses any of which are controlled automatically by a feed-back circuit to compensate for any variation of the test signal. In the Figure, the output from oscillator 1 is integrated at 8 (or alternatively applied to a phase bridge or frequency discriminator) and compared with a reference voltage in a bridge 10, any output from the bridge altering the width (or phase or frequency, as the case may be) of pulses from generator 4. A reflected signal from 13 is detected at 15 integrated at 17 and displayed on a C.R.O. 25 alternately with an attenuated signal similarly detected at 20 and integrated at 22.
