Title: Mould for expanded plastic articles - has ducts for heating and cooling fluid
IPC: B29C44/44
Filed: 1975-03-05
Abstract: A mould for producing expanded plastic articles is in two parts (a) and is surrounded by a steam chamber.

Title: Deterioration resistant membrane for valve - has thin corrugated plastics face with moulded rubber backing
IPC: F16K7/12
Filed: 1975-09-24
Abstract: The membrane (4) has two components, a thin tough plastic or metallic face (4a) backed by a thicker moulded-on rubber portion (4b). Corrugations (13) are formed in the face so that it can elongate when the membrane is forced to curve and contact the seat (8) by the operating screw (10). The region of contact with the seat is left plain and the corrugations are perpendicular to the plane of bending. If the seat is circular, the corrugations are concentric rings around the seat. The function of the rubber backing is to ensure the return of the membrane face to its original corrugated form when the valve is opened.

Title: Earthing rod assembly for overhead power lines - has rod permanently fixed to mast and moved upwards by operating rod
IPC: H01H31/00
Filed: 1975-10-08
Abstract: An earthing rod assembly, for overhead power lines, improving the main patent, is part of the in-situ contacting device. This allows the earthing rod to remain on the mast and for it to be moved simply by the operating rod from 'standby' to 'earth' is required. The line engineer has therefore no need to carry around rods of different lengths in order to earth a line. The earthing rod is held at the top of the mast, parallel to it, and moved upwards when pushed by the operating rod below. Its upper end touches the line contact and earths the line via the conducting part of the mast beneath the insulator.

Title: Aerator for activated sludge plant treating waste water - delivers jet of water via aerating nozzle into recycling tank
IPC: C02F3/12
Filed: 1975-10-02
Abstract: The aerator is of the type using a pressurised jet of liq. to create a moving stream in the surface of liq. in the treatment tank and at the same time to aerate the liq. The jet is delivered from a nozzle with its axis inclined to the surface, i.e pref. at about 30 degrees to the horizontal. A tube inside and pref. coaxial with the nozzle delivers compressed air into an annular jet of liq. as it leaves the nozzle. Outside the nozzle, the compressed air tube pref. has provision for its intake end to be fitted with an air filter. Used for continuously oxygenating liq. in an activated sludge system for purifying waste water. The design greatly enhanced entrainment of air into the jet.

Title: Elbow mould for thermoplastic pipe has a curved parting line - for producing short radius bends with only one operator
IPC: B29C49/48
Filed: 1975-12-23
Abstract: A split mould for reshaping straight thermoplastic tubing to form an elbow has its parting line normal to the radius of curvature. The stock tube is positioned across the ends of the outer shell and progressively bent by the motion of the inner mould moving into the bight of the outer shell. Used esp. for producing elbows with a radius of curvature of =4D, specifically 3D or 2D, where D is the outside dia. of the pipe. Refers to mfr. of embows of PVC pipe with concurrent forming of a socket mouth with the internal seal groove, using complementary retractable mandrels and split external mould blocks described and claimed elsewhere. Use of the mould closing action to bend the pipe reduces the number of attendant operators needed to position the pipe in the mould from three to one, by comparison with use of elbow moulds with the parting line in the plane of the radius of curvature.
Patent FR-2314449-A1 (FR)
IPC: E04F15/18
Filed: 1976-06-04
Abstract: The heater is in the form of a hot water carrying pipe coil supported on a suitable base, such as a sub-floor, and having spaced parallel pipe ducts interconnected by pipe bends. A pair of parallel supporting laths, preferably in the form of flat bars, are fixed on the sub-floor in spaced relation to the opposite side walls of a room to be heated, and circularly curved members are secured to the laths at spacings therealong equal to the spacing between the pipe ducts, the curved members on one lath being staggered longitudinally relative to the curved members on the other lath. The connecting bends of the pipe coil are looped around these curved members, which latter thus serve as a pipe laying gauge. Stop members are secured to the laths in spaced relation to the free ends of the curved members to form, in effect, troughs for the connecting pipe bends. Heat transmitting metal lamellae are secured to the pipe ducts to interconnect adjacent pipe ducts, and these lamellae may be formed with half-shell portions at each end, one overlying a pipe duct and the other underlying the adjacent pipe duct. The lamellae may be formed with alternating rows of depressions and elevations. In hard to heat areas of the floor, the parallel pipe ducts may be arranged much closer together than in the remainder of the floor, as by having a pitch which is one half the pitch of the pipe ducts in the remainder of the floor and, in such case, the curved members in the hard to heat area of the floor have an angular extent of more than 180 DEG  and a radius which is less from that of the curved members in the remainder of the floor. The lamellae may be metal or may be metal powder-containing plastic.

Title: Voltage controlled variable gain amplifier - has three inverting operational amplifiers and variable resistance FET providing temp. independence
Inventor: CREMIERS FRANCOIS AUGIER DE
IPC: H03G1/00
Filed: 1976-10-28
Abstract: Variable gain amplifier whose amplification is controlled from a voltage source. The amplifier circuit is intended to allow this control to be independent of the variable characteristics, i.e. temperature etc, of the circuit components used to control the gain. The circuit consists in its basic form of three operational amplifiers (20, 30, 40) with resistive feedback. Each amplifier is fed from its negative or inverting input, the feedback setting it at virtual earth. Two of the amplifiers supply an FET (36) whose drain-source resistance varies with the input control voltage (14) to one amplifier and sets the gain of the third or output amplifier (30).
