Patent EP-0289399-A2 (EP)
Inventor: CARRE JEAN-JACQUES
IPC: F16D65/78
Filed: 1988-04-21
Abstract: In order to prevent the excessive heating of the brake fluid in the control chambers (20a, 20b), a material (34) for thermally protecting this fluid is placed, for example, in each of the brake pistons (16a, 16b). This material (34) can, in particular, have a melting temperature no greater than a maximum acceptable temperature of the brake fluid, the transformation from solid to liquid being endothermic. This material can also constitute a heat screen covering the inner surface of each piston. Lastly, it may be a heat screen covering those parts of the inner surface of the calliper which face towards the disc and towards the shoes. <IMAGE>
Patent EP-0362452-A2 (EP)
Inventor: JUILLET CHRISTIAN
IPC: E04B1/19
Filed: 1988-08-08
Abstract: The subject of the invention is articulated structures which can be covered with a stretched skin. Their definition is based on the preoccupation of improving their functioning under various stresses. In particular, with regard to their suspension function, they abandon the prismatic shapes which have edges parallel to the force field in favour of pyramids on the peripheral envelope. Likewise, for a radial force field with rotational guidance, the deformation will be axial, this being obtained by localising the elastic elements in the form of a helix. A line of structures is characterised by a ring of polygons having p sides distributed about a central polygon having p-1 sides, particularly being a pentagon. In their deformable version, these structures consisting of modules are used for the production of various rotors, even of variable diameter, and mechanical transmission cables. A line of structures with equal bars is characterised in that it contains a concentric assembly of frames, the height of which doubles from one to the other. A series of plates which are composed of an assembly of tetrahedra and pyramids made isostatic by the elimination of particular bars is characterised by the presence of a chamfer in corners of the serrated perimeter, of a hole and/or of an octahedron carefully placed. A method of using continuous material consists in changing the state of the ambient material by means of a heat pump located in a central region. A specific structure consists of two flanges, each formed from a pentagonal ring, the angular offset of which can be used for many purposes.

Abstract: High speed digital data correlator utilizing as a summing circuit single bit full adder cells in a synchronous pipelined array arrangement to sum the number of bit matches with a selected correlation word in a serial data stream. Each adder cell has up to three inputs and provides a partial sum by adding up to three bits of equal powers of two. The simple full adder cell architecture minimizes interconnect lengths between the adjacent synchronous stages of the summing circuit and maintains near constant circuit density across the stages. These features contribute to an optimization of the operational speed of the correlator for any given circuit technology. The correlator of the preferred embodiment detects two complementary, mutually exclusive correlation words, using the same correlation circuit.

Abstract: The system includes sensors (w) which provide signals indicative of the rate of rotation of at least one monitored wheel of the motor vehicle and electrically-controlled fluid actuators (4-9) for increasing and reducing the braking pressure applied to the braking elements of the vehicle. An electronic processing and control unit (30) connected to the sensors(W) and is arranged to pilot the actuators (4-9) in conditions of incipient locking of the wheels so as to bring about one or more cycles of anti-lock braking. In each of these cycles, the unit (10) causes in succession: 
a controlled reduction of the braking pressure when the at least one monitored wheel is in a condition of incipient locking, 
the holding of the pressure at a constant value until the acceleration of the monitored wheel exceeds a minimum positive threshold, and 
the increase of the braking pressure again. 
     During the stage in which the braking pressure is increased again in each cycle after the first, the electronic unit (10) causes in particular: 
an initial pressure increase of an amount calculated on the basis of the total increase in the previous cycle and the durations of the last and penultimate periods of controlled reduction of the braking pressure, and 
a subsequent, slower increase in the braking pressure.
