Title: Induction heating appts. - with compensation and balancing appts. for triphase power supply using two partial inductors
Inventor: PARENT JOSE
IPC: H02J3/26
Filed: 1974-08-07
Abstract: The inductor consists of 2 partial inductors each transmitting approx. the same active energy to a workpiece; each partial inductor is placed at a given distance from the other to avoid disturbances arising from the dispersion field of the other; they are connected to the 3 terminals of the triphase network, 1 of the terminals being common to both partial inductors; and a range of condensers is connected in parallel to each partial inductor whose power consumption of capacitative reactive energy differs from that required for perfect compensation of inductive reactive energy by a deficit for one partial inductor and by an excess for the other by about 58% of the active energy so that the supply currents for the induction assembly are approx. equal and are relatively dephased by about 120 degrees. Used for heating rolling mill rolls. Avoids use of a phase equipoise appts. but ensure equal distribution of heating power over the 3 phases of the grid.

Title: Synthetic for from knitted fabric having loop pile - of which the loops are broken and pref clipped
IPC: D06C23/00
Filed: 1974-10-03
Abstract: A synthetic fur is produced by knitting a fabric with a loop pile on one surface and breaking the loops with a brushing device to produce imitation hair. The fabric is knitted from synthetic yarns or filaments, and pref. the yarns/filaments forming the loop pile also form part of the base knit. The process has a reduced number of operations thereby allowing the synthetic fur to be made quickly and cheaply.

Title: Pipe connection for metal plate covering concrete casing - useful in nuclear reactors (SW060976)
Inventor: PETIT GUY
IPC: F16L41/08
Filed: 1975-02-07
Abstract: A connection between a metal plate, fixed to the inner face of a concrete wall of an enclosure, and a metal pipe which passes through the concrete, is made by incorporating a reinforcing piece and a sleeve. The reinforcing piece is thicker than the metal plate is at the edge of the hole where the pipe is to be connected. The sleeve is made of a material with a high coefft. of elasticity. The reinforcing piece is fired by its external periphery to the edge of the hole and by its internal periphery to one end of the sleeve. The other end of the sleeve is joined to the pipe. The thickness of the sleeve decreases towards its junction with the pipe. The pipe is surrounded by a metal sheath where it passes through the concrete, and the space between the pipe and the sheath is filled with insualting material. The connection incorporates an annular element, with its inner edge fired to the pipe and its outer edge fired t a flange on the sheath so as to permit free expansion. Partic. useful in boiling water nuclear reactors in which the press. resisting casing is constructed of prestressed concrete. The invention overcomes the problems arising from uneven stresses at joints under excessive working conditions, where pipes pass through concrete into metal covers.

Title: Hydraulic distributor valve for earth moving machine cylinder - has non return flow valves allowing cylinder venting when spool valves moved by control spool operation
IPC: F15B13/01
Filed: 1975-04-07
Abstract: The large capacity hydraulic valve comprises a body (1) in which is fitted a sliding spool (2). Dual springs (3, 4) control spool movement and are in one of two inlet chambers (5, 6). When either chamber (5, 6) is pressurised spool movement causes flow from the other end of the spool, past a spring loaded non-return valve (19, 18) and to one side of a double action hydraulic cylinder (22). The pressure in the chamber (5, 6) operates an adjacent spool valve (37) which allows release of pressure from behind the adjacent non-return valve (19, 18) so that return flow can occur from the other side of the hydraulic cylinder (22).

Title: Printing machine numbering mechanism - has tappet with magnetic head opposite component carrying sheet to be printed
IPC: B41F3/86
Filed: 1975-05-28
Abstract: The printing machine numbering mechanism has, on the same spindle, a number of wheels with characters round the periphery at intervals of 1/nth of a revolution, n being a whole number. Each wheel works with a ratchet wheel, being driven by a claw on a carrier performing a reciprocating movement. The claws are offset so as to rotate the wheels through 1/nth of a turn after a predetermined number of movements of the carrier. The carrier is actuated by a tappet working at right angles to the wheel axis and subjected to the effect of a return spring. The head of the tappet (6), which is opposite the component carrying the sheet to be printed, has a powerful magnetic plate (12), whose field is inclined at the most at a small angle to the direction of movement of the tappet.

Title: Automatic sensitivity control for space surveillance security systems - uses long time constant voltage integrator with capacitor storage
IPC: G08B29/04
Filed: 1975-09-26
Abstract: The automatic sensitivity control system is for an antiburgulary system of the space surveillance type.

The automatic sensitivity control system has a voltage integrator connected as a long time constant integration. This integrator is fed by a voltage proportional to the disturbance level existing in the space surveilled. This voltage is designed to ensure control of the system sensitivity so that the system can only be actuated if the signal received has a voltage amplitude greater than the amplitude memorised in the integrator.

Title: Support insulators for metal encapsulated conductors - are designed so that field lines do not penetrate insulator surface
IPC: H01B17/56
Filed: 1976-06-11
Abstract: To eliminate travelling discharges from the surface of conductor ducts filled with an insulating gas, for example SF6, or with a liquid dielectric such as oil, the insulator surface between the two electrodes (1, 2) is shaped so that the lines of the electric field (17, 18) do not travel for part of their length through the insulator body. An optimum contour is achieved in the integral of the normal field strength along the insulator length approximates to zero. Field lines (16) which are external to the insulator, leaving and entering between points (VII, VIII) near to the electrodes, are permissable, and are not likely to cause discharges.

Title: Jet-assisted guide channel to remove hot blow moulding parisons - for prompt, safe parison recovery after prodn. interruptions
IPC: B29C49/42
Filed: 1976-07-16
Abstract: A guide for deflecting the path of a hot extruding parison comprises a sloping channel or gutter which can move into a position to intercept the path of the descending parison and which has gas jets to assist movement of the parison down the guide. The guide leads the parison to an ancillary system, e.g. a conveyor, bin or sec. guide, for removing the discharged piece of parison. Used to remove and recover parison material from a blow moulding machine if and when prodn. is interrupted further downstream. It is safer than manual deflection of the parison path from between halves of an open mould, and can be actuated to intervene automatically.
