Title: Tapering machine, particularly for metal tubes for drawing
Inventor: CORSINI LUCIANO
IPC: B21C5/00
Filed: 1984-10-04
Abstract: The invention relates to a tapering machine which comprises a fixed platform (1), a movable platform (2) which can be displaced towards and away from the fixed platform and one, two, three or more vices (3) between the two platforms which are designed to taper the ends of the same number of tubes at the same time by squashing. Each vice (3) is constructed of four jaws (10, 11, 12, 13) arranged as the sides of a square and bounding between them an aperture (14) to take a tube. Two jaws (10, 12) opposite to each other are rigidly fixed to the platforms (1) and (2) respectively while the other two jaws (11, 13) opposite to each other can move with respect to the first two against the bias of pneumatic pistons (18, 20) within the space provided by the platforms so as to vary the size of the aperture formed by the four jaws following movements of one platform with respect to the other. <IMAGE>

Title: Viscosity control of natural rubber in the solid state
Inventor: NADARAJAH MURUGESU
IPC: C08K5/37
Filed: 1985-02-04
Abstract: Dry rubber crumb is dipped in a fine dispersion of hydroxylammonium compounds of the formula   <IMAGE> in which R is a thiophenolic, phenolic or a thiol radical and dried at 100 DEG C or above. By using the hydroxylammonium thiophenols, hydroxylammonium phenols and hydroxylammonium thiols singly or in combination at the appropriate concentration, it is possible to prepare NR of any required Mooney Viscosity from dry NR. Since the surplus dispersion, after dipping the granules, can be drained off and collected for re-use, there is no effluent problem as occurs in prior art methods when soluble hydroxylamine salts and sodium salts of thiophenols are added to latex.

Title: An improved flexible elongate optical fibre cable
Inventor: TAYLOR JOHN EDWARD
IPC: H01B7/17
Filed: 1985-03-13
Abstract: ) An overhead electric conductor comprises a central tubular metal core 52, at least one layer 55 of helically wound bare metal wires surrounding the core and, loosely housed in the bore of the core, at least one optical fibre element 11. The optical fibre element 11 comprises a flexible tube 17 of elongate transverse cross-section in which is loosely housed an optical fibre ribbon structure 12 and which is resiliently set in such a form that it follows a path of smoothly curved undulations, the axes of curvature of which lie parallel to one another and normal to the axis of the tube. Should a tensile force applied to the overhead conductor be transferred to the loosely housed optical fibre element, the flexible tube of the element will tend to straighten in a lengthwise direction against the action of its resilient set thereby to reduce any tensile force that might otherwise be applied to the optical fibres and, when the tensile force is removed, the tube will return under the action of its resilient set towards its original form.

Title: Automatic control of engine speed
Inventor: DANNO YOSHIAKI
IPC: F02D41/36
Filed: 1985-05-18
Abstract: Stabilization of the idling speed of an internal combustion engine of the type in which the number of cylinders working is variable is effected rapidly by providing a generator control means capable of suppressing or stopping power generation of a generator driven by the engine in the event the engine speed decreases below a predetermined value when less than all the cylinders are working. Additionally means are provided to adjust the amount of intake air to the engine, regardless of the number of operating cylinders, whereby the engine speed is stabilized through control of generated energy in the short term and through control of the amount of intake air in the long term.

Title: An amusement device
Inventor: WOOD RONALD ALFRED ERNEST
IPC: A63F9/08
Filed: 1985-07-05
Abstract: An amusement device and puzzle comprises a stack of rebated discs, preferrably in the shape of a sphere, mounted on an axle for relative rotation. The rebated discs form a maze of pockets and annuli with access through holes and gates. Coloured balls contained within the device are located at a home base and, by a sequence of rotary moves of the discs relative to each other and by tilting the axle, each ball may be transferred through the maze of labyrinths, gates and holes to an away base. The periphery of each disc is marked with characters to identify the positions of the pockets, blind and open, also to enable the relative position of each disc to datum points on the bases to be observed. The puzzle has one solution for the smallest number of moves which is unique to each device for a very large number produced. <IMAGE>

Title: Decoding method and apparatus for biphase coded signals
Inventor: SUMMERLING GEOFFREY WILLIAM
IPC: H03M5/12
Filed: 1986-02-06
Abstract: A method in which a biphase coded data stream is sampled before S1 and after S2 a regular data transition (figure 4c). These samples S1, S2 are then compared to produce a decoded data output signal (figure 4i). This method overcomes problems arising where the data stream is distorted and transitions do not cross any assigned signal threshold.   The method may be implimented using a pair of sample-and-hold units, a comparator and a latch. It is applicable to Biphase Codes where regular transitions occur mid-bit (eg. Manchester II, Inverted Manchester, Biphase L), as also to Biphase Codes where regular transitions occur at end-of-bit (e.g. Manchester Mark, Manchester Space, Biphase M). <IMAGE>
