Patent FR-2223809-A1 (FR)
Title: Rocking blade electrical switch - has mobile contact gripped in stirrup shaped housing to give better operating pressure
IPC: H01H23/12
Filed: 1973-03-30
Abstract: The mobile blade of the switch is a shallow 'V' shape and is gripped laterally at the middle by a stirrup shaped piece that also acts as an electrical contact for the blade. The snap action toggle acts on either side of the V and is so mechanically arranged that it applies maximum pressure to fixed contact through the mobile blade. In this way the current rating of the contacts may be increased. The switch is used as a two-way switch which is off when the switch lever is in its central position.

Title: Portal or travelling grab crane - is operated by hand or automatically with telescopic guide
IPC: B66C13/48
Filed: 1975-04-29
Abstract: The portal or travelling crane has a single or double gantry beam and a crab travelling on the beam with a hoist mechanism and a slewing or non-slewing grab. The grab (9) can be either directly operated from a hand press-button switch box (11), or automatically by signals from an electronic unit. In the latter case, the grab is actuated by a hydraulic or other suitable mechanism (6) via rams (7). The crab (2) has a vertically telescoping guide (5), on whose free end the grab is mounted. Under hand control the guide telescopes freely, but with automatic operation it is locked in a particular position, so that the only vertical movement of the grab is that imparted by the rams. Locking of the guide can be by an electromechanical mechanism initiated by a signal, which simultaneously couts out the hand control and energises the automatic system.

Title: Metal rod as prosthetic insert into a bone shank - has longitudinal depressions filled with material promoting growth of bone cells
Inventor: BLANQUAERT DANIEL
IPC: A61F2/02
Filed: 1975-07-01
Abstract: A metal rod adapted to be prosthetically inserted into an invalid's bone shank (e.g., the shank of a femur) has >=2 longitudinally extending depressions filled with a matl. that facilitates and promotes the renewal of bone cells. This matl. is surrounded by a metal grid whose mesh width is >=0.3 mm. and which is welded to the ribs of the metal rod extending between the depressions. Used e.g., is construction of hip bone prosthesis. A firm and reliable bond between prosthesis and natural bone is achieved but the resulting structure is not so compact that formation of blood vessels necessary for blood supply to the freshly growing bone tissue is prevented. Smooth surface of the metal improves resistance to corrosion. The metal grid may be a net of a perforated metal sheeting. It is impregnated (sic) with a biologically decomposable organic matl. adapted to facilitate growth of bone tissue. This matl. may be applied to the depression s by casting. The following matls. are suitable: polylactic acid, polyglycolic acid, a polylactide (I), a polyglycolide (II), tricalciumphosphate. Alternatively, biologically compatible mono- or poly-crystalline fibres, esp. carbon fibres, may be used.

Title: Zinc-elastomer complex - providing seal between two metal elements without welding, e.g. for repairing metal roofing
IPC: E04D5/14
Filed: 1975-08-19
Abstract: complex comprises a band of Zn, a band of silicone-treated paper, and an intermediate layer of highly adhesive, non-polymerisable, elastomeric mastic. Pref. the Zn band is made of high-purity rolled Zn with a thickness of approx. 0.1 mm., and the band of silicone-treated paper has a width larger than that of the Zn band and elastomeric layer, to protect them and allow treatment in different forms e.g., while flat, on a reel, etc. The elastomer e.g., "EC 5313" is non-polymerisable so as to maintain its physico-chemical properties in various media, even at the end of long periods. Used e.g., for repair of metal roofing.

Title: Mixing valve for bathroom shower - has hemispherical baffles in chamber with horizontal outlet to head
IPC: F16K11/00
Filed: 1975-08-20
Abstract: The mixing valve has a cylindrical body (2) with a threaded inlet (6) for attaching to the collecting chamber for both hot and cold water streams. The outlet (8) is attached to the flexible pipe leading to the shower head and the flow is controlled by the tap (12). As the water flows through the valve, it passes around the outer edge of the hemispherical baffle (13) and then through the holes (16) in the larger baffle (14). The two baffles are joined together by a boss (15) and clamped in a recess (17) by the threaded end (7) of the tap (12). The turbulence induced in the water by the baffles (13, 14) ensures complete mixing of the hot and cold streams.

Title: Lashed cable support bar - has forked ends with tine gaps shaped to match support flanges for interference fit
Inventor: VANDRIESSCHE GUY
IPC: H02G1/00
Filed: 1975-10-09
Abstract: The support consists of a bar (1) having forked ends (2,3) the gap between the tines being shaped to match the edge of the support flanges (9,10) and dimensioned to be an interference fit on the flanges. Notches (6) are formed at approximately mid length of the bar, to prevent the lashing (7) from slipping. The fork tines are the same width as the bar and form parallel sections staggered away from the plane of the bar. These sections engage the rectangular holes cut in a special assembly tool which rotates the bar to lie at right angles to the support edges, once the latter have been engaged in the appropriate fork ends.
Patent FR-2333315-A1 (FR)
IPC: G10L25/90
Filed: 1975-11-25
Abstract: A detection circuit for the significant peaks of a speech signal, comprising first and second detectors respectively for detecting the positive and negative peaks of said speech signal. Each of these detectors is followed by a peak charging circuit comprising a first integrator having a relatively large discharge time constant and a comparator comparing the detected speech signal and the output signal of said first integrator. Each peak charging circuit comprises in addition a second integrator having a relatively small time-constant. The discharge of the first integrator is effected up to a voltage equal to the output voltage of the second integrator, and the discharge of the second integrator is effected down to a voltage depending on the output voltage of the first integrator. The two integrators of each peak charging circuit provide a non-exponential decreasing signal which has an inflection point following a significant peak in the original speech signal.

Title: Temp. and voltage compensated electret sensor - has sensing circuit connected to two conductive layers for specified compensation
IPC: G01L1/16
Filed: 1976-02-09
Abstract: The sensor has an electret layer of polarised material with both piezoelectric and pyroelectric properties. The layer generates electrostatic charges of opposite polarity on its surfaces under the effect of temperature and voltage variations. One side of the electret layer is in close planar contact with a conductive layer. A second electret layer of the same properties is arranged parallel to the first layer and has also a second conductive layer. A third conductive layer is sandwiched between the other sides of the two electret layers. An electronic sensing circuit (10) is connected to at least two conductive layers in such manner that, when the electret layers are exposed to identical temperature changes and opposite voltage changes, the circuit picks up the electrostatic charges, while not responding to electrostatic charges due to the other change of the two states.
