IPC: G01S1/02
Filed: 1975-04-04
Abstract: The system consists of four transducers arranged in pairs at right angles to each other with the distance between them small in comparison with the wavelength, corresponding to the highest received frequency. The transducers are connected through variable gain amplifiers to a summing element followed by a 90 deg. phase shifter, and in pairs to differential circuits. This phase shifter is connected to the input of an amplifier whose gain is proportional to the spacing between the transducers, multiplied by the highest received frequency.

Title: Vehicle location w.r.t. predetermined trajectory - using radio beacons memory and associated electronics with readout facility
Inventor: VIRNOT ALAIN
IPC: G01S5/02
Filed: 1975-07-11
Abstract: A technique is described for locating a vehicle w.r.t. a predetermined trajectory which crosses regions which are covered by radio beacons or markers. At certain points on the trajectory, the information provided by two or more beacons is recorded. During a subsequent journey, similar information is detected from the same beacons. Using the actual information from each beacon, the point on the trajectory which corresponds with this information is obtained by referring back to the pre-recorded information. This enables the transverse deviation in the actual position of the vehicle w.r.t. the trajectory to be determined from the distance between the two known points on the trajectory. The associated equipment comprises a sensor (2) which detects the information from the two beacons; a memory (6) with a read-out facility; and a system (1) which provides an electrical signal indicating the distance separating the two points obtained on the trajectory.

Title: Two-stage blow moulding of polyolefins - first at low and then normal pressures
IPC: B29C37/00
Filed: 1975-09-29
Abstract: Polyolefin articles with a shiny outer surface are produced by mixing the polymer under strong compression, extruding a parison into a mould, establishing a temp. gradient between the parison wall and the mould wall, the gradient being of such magnitude and applied during such time as to allow the surface of the parison to remain molten and prevent formation of crystalline aggregates, and finally applying the parison wall against that of the mould. M)thod may be used for prodn. of containers e.g., bottles. Besides having an attractive appearance, the prods. are also mechanically stronger than conventionally blow-moulded prods.

Title: Site joint system for precast members reinforced concrete frame - uses bar tendons in linear ducts and with screw jacks to form structural joint
IPC: E04B1/21
Filed: 1976-10-05
Abstract: The site-joint for precast reinforced concrete frame uses a system of bar-tendons (9) and wedges (15) to provide a definitive moment of resistance at an otherwise dry-joint. The joint may esp. be used in portal frames. It joins roof (4) and leg (3) members at the angles between the two members and enables the legs to be pinned at their bases. The ends of the conjunctive members may be single stepped, and each member (3, 4) may be traversed by four similarly and symmetrically disposed longitudinal holes (7). Two holes open out on each vertical face (6) of the member-end, and transverse openings (10) meet each hole (7) at a fixed short distance from the member-end. Threaded bars (9) are placed in each hole (7), traversing the joint, and are anchored in each opening by a nut (13) and washer (22). A tubular screw-jack (15), fitting over each bar (9) between members, ensures traction across the joint and provides tolerance.

Title: Remote control tensile cables with synthetic monofilament core cable - for low wear rates and intrinsic damping of tensile impulses
IPC: F16C1/20
Filed: 1977-01-03

Title: Inlet valve for road fuel tanker - has hinged flaps which augment lift of valve plate during operation
IPC: F16K27/07
Filed: 1977-02-03
Abstract: The inlet valve for a road fuel tanker has a housing (1) with a seat for a valve plate (2). The valve plate slides on a rod (4) attached to a diaphragm (3). The valve plate (2) is supported on the rod by a pair of hinged flaps (5, 6) mounted on pins (4a, 4b). The lower end of the rod (4) is guided by radial arms (7) sliding in the bore (8). When fuel flows into the valve the pressure acts on the diaphragm and raises the valve plate off its seat so that fuel can flow into the bore. As the flowing fuel impinges on the flaps, it swings them into the vertical position. This movement of the flaps pushes the valve plate upwards to increase the opening of the valve.
