Title: Gear-change device for a multi- ratio cycle hub
Inventor: KLAUKE DIETER
IPC: B62M11/16
Filed: 1984-02-02
Abstract: The gear-change device (1) comprises a securing part (5) screwed on to the threaded end of a hub spindle (3) of the multi-ratio hub (1) and a distance-compensating part (17) guided displaceably in relation to the securing part, which part (17) is arranged in a gear-change force path of the multi- ratio hub (1), leading from a manually actuatable actuating cable by way of a deflection element (27) to a gear- change element (13), in such manner that it can allow delay between movement of the actuating cable and movement of the gear-change element (13). The distance-compensating part (17) is supported on a spring (57) acting against the distance-compensating movement, the force of which spring is greater than an oppositely directed force exerted on the gear-change element (13). A detent device (47, 53) defines the positions of the actuating cable in relation to the distance- compensating part (17). The distance- compensating part (17) and spring (57) allow pre-selection of gears when the gear elements are locked by drive torque. <IMAGE>

Title: Boundary air layer modification structure for heat transfer roll
Inventor: GROSS FRANK R
IPC: F26B13/14
Filed: 1984-08-14
Abstract: The boundary layer of air between a web and a heat transfer roll (22) is eliminated as far as possible by a squeeze roll (20) positioned between the heat transfer roll (22) and the web to squeeze boundary layer of air attached to the web out prior to web contact to the heat transfer roll (22).

Title: Method of manufacturing bordeaux powder
Inventor: HUGHES ALAN CHARLES
IPC: A01N59/20
Filed: 1984-08-16
Abstract: The invention concerns the manufacture of the copper-based compound (tricalcium tetra copper hexahydroxide tetra sulphate (TTCHTS)) used as a fungicide and called "Bordeaux Powder" or "Bordeaux Mixture". The method comprises mixing together, in the dry state, a copper sulphate hydrate salt either with the oxide or hydroxide of calcium, and subjecting this dry mixture to milling for a reaction period wherein the compound TTCHTS is formed in the presence of free water liberated from the copper sulphate hydrate salt during the milling. Preferably, the mixture is comprised of copper sulphate pentahydrate and calcium oxide. The invented method presents advantages over the traditional wet process in which the compound TTCHTS is formed by admixture of aqueous solutions and precipitation.

Patent GB-2191872-A (GB)
Title: Optical fibre cables
Inventor: WORTHINGTON PETER
IPC: G02B6/44
Filed: 1986-06-17
Abstract: A method of making very long length e.g. 50km of optical fibre submarine cable in which acrylate-coated fibres (5) are guided by a fixed lay plate (l0) and embedded by a fixed trumpet shaped die (7) in a relatively soft thermoplastic polymer coating (3) (e.g. Hytrel-RTM) with a zero lay angle. The coating (3) is heat softened and carried on a kingwire (2). The partially-embedded fibres are encased in a second coating (l2) of the polymer by conventional extrusion. The element is coated with a water blocking material as the element is encased in a tubular strength member comprising a conductive tube of copper or aluminium surrounded by two layers of high tensile strength wires. A dielectric sheath of e.g. natural polyethelene is extruded over the wires. The structure of the cable limits the bending of the fibres to e.g. 0.6m, so that very low losses can be achieved.

Title: Colloid analyzer
Inventor: MARLOW BRUCE J
IPC: G01N29/024
Filed: 1987-06-26
Abstract: A colloid analyzer is provided employing a relatively low frequency, low power, continuous "acoustic" wave signal propagated in the direction of spaced electrodes 16 mounted adjacent to the side wall of a chamber or vessel 12 containing a colloid sample 10. The chamber further comprises a series of probes 46,44,48, for respectively sensing the pH, temperature, and conductivity of the sample(s) being analyzed. A piezoelectric transmitter 14 generates the acoustic drive signal. The spaced electrodes 16 in conjunction with an electronic signal processing circuit 20 serve as a receiver and generate an output signal relating to the magnitude and polarity of the zeta potential of the particles being "acoustically" excited by the drive signal. Computer means 28 responsive to the signal processing circuit's output signals and/or the vessel probes' output signals develop a graphical output 30 relating to zeta potential, and/or one relating to the surface charge density of the analyzed colloid for given levels of titration. Optional means are provided responsive to the output of the signal processing circuit for measuring the degree of flocculation of the colloid sample in the vessel. <IMAGE>
