Title: Transmission for an automobile vehicle comprising two slidable homokinetic joints
IPC: F16D3/84
Filed: 1979-12-13
Abstract: The transmission comprises two slidable tripod joints. In each joint, the tulip element is extended around the shaft of the tripod element by an abutment member which defines a concave part-spherical surface. A check member having a convex part-spherical surface fitting the concave surface is disposed around the shaft between the tripod element and the abutment member with a radial clearance which is at least equal to the amplitude of the orbital movement of the tripod element at the maximum angle of deviation of the joint. Each joint has a spring which is compressed between the inner end of its tulip element and the adjacent end of the shaft. In this way, the maximum extension of the transmission is distributed equally between the two joints and the shaft is constantly centered so that noise and wear of the check members is avoided. The invention is in particular applicable to transmissions for independent rear driving wheels of automobile vehicles.

Title: Hollow-plate heat exchanger
IPC: F28F3/08
Filed: 1980-07-01
Abstract: A hollow-plate element providing a fluid pass for a heat exchanger (e.g. a refrigerant evaporator) comprises a pair of plate members joined together at their edge portions and forming between plate midportions a flow path for said fluid extending between inlet and outlet manifolds formed at the ends of the element by configurations 28'.

The ribs prevent direct linear flow across the rows between the inlet and outlet manifolds. At one end at least of each row the ribs e.g. 42e, 42h are spaced from the edge portion of the plate to provide for reduced pressure drop, a channel 60 forming a by-pass flow relative to the tortuous flow across the ribs 42.

Title: Variable valve timing mechanism for an internal-combustion engine.
IPC: F01L13/00
Filed: 1980-12-29
Abstract: An internal combustion engine having at least one cylinder with inlet and exhaust valves operated via rocker arms by respective cams carried by a single camshaft. The camshaft is connected to its drive by an eccentric linkage, the eccentricity of which is varied by a device responsive to engine speed, and is least at high speed. As engine speed falls, increasing eccentricity results in a relative advance of inlet valve closing time and relative retardation of exhaust and inlet valve opening times but little change in the timing of exhaust valve closure. The lift of the valves may be varied also if the rocker arm axes are movably mounted.

Title: Underwater seismic testing.
IPC: G01V1/04
Filed: 1981-09-22
Abstract: The invention relates to a method of estimating the acoustic signatures of seismic sources, used in underwater seismic surveying, in order to obtain more accurate data on their wave form in the far field. The pressure response produced by an array of sources is sampled by a hydrophone array larger in size than that of the array of sources and positioned relatively far from the array of sources the individual response of each of the hydrophones in the hydrophone array is measured separately, and the wave form of the source array signature is calculated from these measurements. The hydrophone responses can be analysed in order to give a numerical reconstruction of the configuration of the source array together with its reflected image at the water-air boundary, or they can be extrapolated directly to the location of interest in the far field.

Patent ES-8403221-A1 (ES)
Title: Instruction prefetching data processing apparatus including a conditional branch instruction predictor.
IPC: G06F9/38
Filed: 1983-01-14
Abstract: Instruction prefetching data processing apparatus is adapted for predicting the outcome of a conditional branch instruction based on the previous performance of the branch, rather than on the instruction fields. The prediction of the outcome of a conditional branch instruction is performed utilizing a decode-time history table (6) that records the history of the outcome of the branch at a given memory location. The predictor attempts to guess only the outcome of a conditional branch instruction, but not its target address and can only be used to guess the branch outcomes at decode time when the target address is available. The table is accessed using the memory address of the branch instruction itself or some portions thereof. The table records the history of the outcomes of the branch at this memory location up to the congruence of the table size. A combinational circuit (18) determines the guess (taken or not taken) from the branch history as provided by the table.

Title: Improvements relating to the manufacture of polyurethane coated materials by the transfer coating particularly imitation leather materials
IPC: C14B11/00
Filed: 1984-11-20
Abstract: Polyurethane-coated products, particularly artificial leather, utilise a substrate (e.g. a transfer paper) which passes through a series of operations. The successive stages are storage and feeding devices, polyurethane coating machines, spray guns, drying ovens together with the appropriate calenders, cooling plant, separators etc. When the substrate (e.g. transfer paper) has been coated with polyurethane and any other materials desired, it is passed through a short tunnel oven and heated by shortwave infrared radiation with approx. 1,200 nm wave length; mirrors in the oven direct the radiation on to the polyurethane coating so as to dry it off and ensure the vaporisation of solvents present but without significantly heating the top surface of that coating.
