Title: Tool for mfg. aluminium sections with metal coating - applies coating by extruding section and passing metal strip through die
Inventor: WATTIER JEAN-MARY
IPC: B60M1/30
Filed: 1974-10-14
Abstract: The tool is for the manufacture of aluminium (or aluminium alloy) sections with a partial coating of wear resistant material, particularly rails carrying an electric current. The sections are produced by extrusion, and the wear-resistant material applied by passing a ribbon or strip of the material through the die at the same time. The strip has a coating of aluminium on one side to affect the joint. Two such strips can be passed, back to back, between two sections being extruded. The extrusion die is of the bridge type, and has a guide system to feed in the strips.

Title: Patient's in hospital bed monitor - has circuit generating alarm signal on patient's absence by breaking pressure responsive switch
IPC: H03K17/94
Filed: 1974-10-28
Abstract: The circuit is used to provide an alarm signal when a patient disappears from a hospital bed, in order to alert the hospital staff. The hospital bed incorporates a pressure-responsive switch (12), which opens when the patient leaves or falls from the bed, this switch (12) being connected to the grid electrode of a field-effect transistor (10), the latter remaining non-conductive while the switch (12) remains closed. The opening of the switch (12) allows a current to flow between the source and drain of the field-effect transistor and through an acoustic alarm circuit connected across the latter. Means for delaying the generation of the alarm signal may be connected to the transistor gate.

To the solenoid is attached a shaft which carries a pawl which engages in the teeth of one of the parts of the racks. Another pawl is connected to a fixed part of the device so as to engage into the teeth of the other part of the rack. The parts of the racks are respectively formed on two parallel arms which are connected to the slide and extend towards the solenoid.

Title: Trailer for carrying loose material - has hinged sides with internal panels raised at longitudinal centre to speed unloading
IPC: B60P1/16
Filed: 1974-12-06
Abstract: The trailer for loose material has two hinged longitudinal panels (2, 3) on its sides. The lateral trailer faces have lower panels (8, 9) hinged on a horizontal axis. The longitudinal panels are separated by a central stop (13) to limit their movement upwards. The panels partly overlap, a stop (14) being fixed to the edge of the upper panel. To unload, the trailer the side panels (2, 3) are dropped and the lower panels (8, 9) are pushed up by a ram (8) to speed up unloading of the final amount of material carried. The arrangement avoids having to tip the whole body of the trailer sideways.

Title: Warp knitting machine, esp. a sew-warp knitter - laying in the weft with fewer broken ends
Inventor: KEMTER HEINZ
IPC: D04B23/12
Filed: 1974-12-26
Abstract: In the yarn supply arrangement for a warp knitting machine, such as a new-warp knitter for the prodn of fabrics with weft threads bound in at right angles to the line of motion of the carrier fabric, the weft comes from a supply creel in the immediate proximity of which it passes a first braking point, and continues as a uniform chain of threads through guides to be drawn into a weft thread laying-in device which moves between two reciprocating weft transport details, by means of which the threads are opened out and fed to the stitch forming station of the machine. Close behind the first braking point, a typical frictional yarn delivery arrangement is positioned directly before a standard thread guide located parallel to the opened-out weft threads which divides the chain into >=3 equal separate chains of threads moving in similarly inclined planes to the weft laying-in device. The tension on the weft ends is reduced and maintained constantly, eliminating diagonal striping.

A point of connection between one input path and one output path is provided by a cable section directly connecting one output of the associated input selector and one input of the output selector associated with the output path.
Patent FR-2308709-A1 (FR)
Title: Open end spinning by feeding fibres onto rotating perforate drum - to which suction is applied, and taking up yarn axially
IPC: D01H4/06
Filed: 1975-04-25
Abstract: Open end spinning of yarn is effected by combing a supply of fibres to produce opened fibres which are blown as a jet onto the surface of a rotating perforated roll. Beneath the surface of the roll in the region where the fibres land, a suction is applied obliquely (pref. at an angle of 45 degrees) to the surface of the roll whereby the combined action of this suction and the rotation of the roll spins the fibres into a yarn which is withdrawn axially from the roll. The device is simple and applies a good twist (not just a simple helical twist) to the fibres thereby increasing the strength of the resulting yarn.
Patent FR-2310740-A1 (FR)
Title: Bone fracture mending equipment - exerts force on pin mounting at right angles to plane of fracture
IPC: A61B17/64
Filed: 1975-05-16
Abstract: The equipment mends bone fractures with the aid of two or more pins (7, 8, 10, 11) secured to the respective bone fragments and to mountings (6, 9), the latter being pressed towards each other by an adjustable force. The force is exerted along an axis (15) parallel to a line (4) perpendicular to the plane of the fracture (5), and arrangements can be made for measuring it. A screw (12) can be used to produce the force between the mountings, these then being locked in position on supports.
Patent FR-2272376-A1 (FR)
Title: Method to determine system natural frequency - uses oscillations and measurements of internal random processes
IPC: G01H13/00
Filed: 1975-05-16
Abstract: Resonance curves are obtained by frequency analysis of the signals, and from them the system resonant frequencies and damping are derived. Periodic components are eliminated from the signals before analysis. Spectral and power density functions are determined by a frequency analyser and the autocorrelation function of the signals determined by a correlator. An oscillation pickup responds to the mechanical oscillations, and a frequency analyser processes its electric signals. The damping factor is related to the ratio of the frequency band width and the resonant frequency by a simple algebraic equation.
