Title: Earthquake proof protection for buildings - consisting of composite blocks of metals and elastomer between base and foundations
Inventor: JOLIVET FRANCOIS
IPC: E04H9/02
Filed: 1975-07-01
Abstract: Protection for buildings against large horizontal dynamic forces, and partic. against earthquakes, consists of a system of frictional supports in the form of mutually supporting blocks for the buildings or their foundations. The top blocks are metal plates, the others have a top metal plate, an elastomer sheet and a lower plate to distribute the load. There is also a means for displacement between them at the faces of their opposite supports. The static and dynamic coeffts. of friction of the surface in contact with each other lie between min. 0.08 (tolerable for the permissible displacements) and max. 0.5 (tolerable for the threshold internal resistance of the building). System limits the effects of horizontal earthquake or explosion waves to a set known value, use of appropriate frictional supports enables application to other earthquake conditions than those preselected.

Title: Automatic sequential programmer timing system - has photocell connected to circuit to synchronise system with daylight hours
IPC: G05B19/07
Filed: 1975-08-01
Abstract: Electronic circuit providing control of sequential operations linked to sunset and sunrise, such as domestic central heating. The design intends to overcome timing difficulties associated with the variation in daylight hours throughout the year. The control is based on the use of a photoelectric cell and the delay networks controlling the switching of transistors. These in turn drive relays bringing in further timing circuits as the program demands and the appropriate domestic appliances. Each individual delay circuit has two transistors connected as a Darlington pair, the final emitter directly driving its own relay. The photocell delay initiating the sequence may be reset by a push-button switch short circuiting the capacitors charging resistance momentarily.

Title: Parallel conductors protector system - uses voltage measurement to determine presence of short circuit in one cable
IPC: H02H7/26
Filed: 1975-09-23
Abstract: The apparatus is used for selective protection of electrical power cables against faults to ground from one of several phases. The circuit provides protection for a minimum of three conductors in parallel and may be extended to cover conductors in excess of this number. Circulating current levels are detected in each cable without the use of extra lines or sensitive homopolar devices by measurement of the associated voltages. Selective interruption of the lines is controlled by transformer fed circuits providing a comparison and memory facility for each line with respect to the remainder. Premature operation of contactors is avoided by use of delay circuits, selection being achieved using logic techniques. The system detects the presence of fault currents (11 and 12).

Title: Connection system for quartz glass light guide fibres - is by irradiation of parts of fibres using focussed carbon dioxide laser beams
IPC: B23K26/21
Filed: 1976-09-09
Abstract: Light guide fibres made of quartz glass may be joined by irradiation of parts of the fibres using focused carbon dioxide laser beams. At least a section of the outer surfaces of parts of the light guide fibres to be connected is irradiated with a focused carbon dioxide laser beam of a wavelength which is absorbed by the fibres. During the fusion process short sections of the light guide fibres are placed one upon another in an axial direction. Since the light guide fibre (11) has a small diameter (d), heat convection is produced uniformly in the entire terminal face of the fibre.

Title: Sepn. of aq. and oily phases of a mixt. - by circulation through a coalescer made of synthetic fibres followed by decanting
Inventor: BRAS JEAN-PAUL
IPC: B01D17/04
Filed: 1977-02-15
Abstract: The mixt. is passed into a tranquillisation vessel where some sepn. takes place, then circulated through an enclosure containing a coalescer medium at such a rate that the flow is between laminar and full turbulent flow. The coalescer medium is made up of sheets of oleophile fibres a few cms. long, e.g. polyester bound by a resin, oriented perpendicular to the flow. One or more plates of the cloth having density of 0.1-10 kg/m2 make up the coalescer mass. After the coalescer is a decanting vessel for sepn. of the phases. In the tranquillisation vessel and decanting vessel, the interface of the 2 sepd. phases is kept above the level of the coalescer. This prevents the upstream and downstream faces of the coalescer from being wetted by the light phase. Used for sepn. of aq. and oily phases, e.g. domestic fuel oil from towns water. System ensures an energetic coalescence and satisfactory sepn. no matter what proportion the phases are in.

Title: Washing machine water flow control valve - has electrically heated bimetal blade which operates valve member
IPC: F16K31/40
Filed: 1977-05-20
Abstract: The compact valve may be used on a washing machine to control the circulation of a fluid under pressure. The obturator is displaced by harnessing the deformation of a heat sensitive bimetal blade (28), its temperature being raised electrically cy contact with an electrical resistance coil (33). The valve has an upper part (1) and a sealed lower chamber (2), the former incorporating a fluid inlet (4) and a fluid outlet (6), and the latter incorporating the obturator (18) with the electrical gear. The rim (7) of the outlet (6) forms the seat of the valve, and a flap (10, 11) in a mounting block separates the two chambers (1, 2). When the bobbin (33) is energised the blade (28) is heated and adopts and elliptical expanded form. This displaces a stirrup (30) attached to the obturator (18) which displaces, removing the support from the flap. Fluid pressure then causes the valve to open with the flap moving away from the seat (7).
