Title: Production of mould pairs for flow regulators
Inventor: MANNESMANN REINHARD CARL
IPC: G05D7/01
Filed: 1984-01-18
Abstract: The invention relates to a method of making a fluid flow regulator, in which an elastic ring acts in response to pressure against a profiled core or an inner surface of a casing. It is possible with this method to perform matching of the regulators to a desired value quickly and without excessive waste. To this end the casting moulds for the profiled core or the inner surface are finish-machined in a certain way in dependence on the flow characteristic of the regulator.

Title: A valve link-up arrangement for the control of the clamping cylinders of section forming machines
Inventor: LABS DIETRICH
IPC: F15B11/16
Filed: 1984-02-23
Abstract: The valves required for controlling the three clamping cylinders and the table working surface of section forming machines with a transverse bending capability are arranged in longitudinal and vertical linking. The problem is to improve the forming technology for longitudinal and transverse bending and to optimise the efficiency of the hydraulic system. For the control of the clamping cylinders and the table working surface, all valves are linked in a link-up allowing longitudinal bending at different clamping pressures while preventing the formation of wrinkles between the jaws and providing for transverse bending to be performed by applying the working pressure of the transverse bending ram to the lateral clamping cylinders in such a way that a continuous transition between the individual transverse bending strokes comes about on the section.

Title: Video disc playback system
Inventor: WINE CHARLES MARTIN
IPC: G11B9/06
Filed: 1984-05-23
Abstract: An interactive disc system is provided. Information representative of a first program content is provided together with information of a second program content on a record disc 12 having a single spiral track. When an interactive section of the disc is played the player 10 is provided with two pieces of information so that it may track the correct information. One piece is provided by the system user who selects 31 the sequence to be viewed. The other piece is the digital information 26 on the disc which tells the player where the program being transduced is and where the transducer has to go to be in the desired program. In one embodiment, the spiral track is formed as a groove on the disc surface and the stylus cooperatively engages the groove. In a further embodiment, the first program content is interlaced with the second program content and a kicker is automatically operated to follow the selected program throughout the remainder of the recording, as shown by the respective track series marked by circles, squares and triangles in Figure 2. <IMAGE>

Patent GB-2183568-A (GB)
Title: Vehicle for sport & pleasure
Inventor: JELFS STEWART DUDLEY
IPC: A63C5/03
Filed: 1986-05-15
Abstract: The vehicle in its basic wheel-mounted form utilises the steer-by-leaning principle as in the well known skateboard. It has, however, strengthened axles and modified suspension designed to give improved control. Furthermore, it has handlebars, seat, footrests and knee-rest. The configuration of these features, especially the knee-rest and handlebars, greatly extends the scope of operation and improves safety. In its second mode, the vehicle is a steerable skid-mounted toboggan. Conversion to this form is achieved by replacing the wheel and axle assemblies with a pair of articulating skids. In this form it can be used on snow or artificial ski-slopes. <IMAGE>

Title: Extruding sheaths around intumescent cores
Inventor: PATTERSON KEITH RICHARD
IPC: B29C48/07
Filed: 1987-03-20
Abstract: A process for sheathing elongate intumescent fire-sealing core materials (40) with a thermoplastics material e.g. PVC, or nylon, comprises extruding the plastics material through an annular orifice (32) in a cross-die head (10), feeding the core material (40) having a cross-sectional area less than that enclosed by the annular orifice (32) through the die head (10), such that the extrusion (42) converges thereon at a position remote from the die head (10) to encase the core intumescent material (40) in a thermoplastics sheath. The process avoids deterioration of the intumescent material, that would otherwise occur by contact of the materials within the extrusion die. <IMAGE>
