Title: Mould for injection moulding
IPC: B29C45/37
Filed: 1979-10-05
Abstract: A mould, particularly suitable for injection moulding of large dimension casts from plastics without internal stresses and with accurate dimensions comprises base plates 1 in which cooling grids 2 are embedded and the active surface 7 of the base plates is provided with forming plates 3 and forming strips 4 with grooves 8, 9 for heating elements or tempering and cooling means, and mobile cores 12 are secured in the mould by respective fixing bolts 13 which allow the core position to vary in the course of shrinking of the solidifying plastic.

Title: Steerable beam antenna
IPC: H01Q3/24
Filed: 1980-05-13
Abstract: A steerable beam antenna comprises a plurality of radiating elements e.g. dipoles arranged in an arc or complete circle. Each element has associated therewith a switchable phase shifter, other elements may also have fixed phase shifters. A microwave source, or detector, is selectively switched to an odd number of adjacent elements with the centre element connected through its associated switchable phase shifter. The combined result of the phase shifters is to form a beam of radiation extending from the central radiating element. Thus the beam may be steered through 360 DEG  by appropriate switching of power and phase shifters. A single microwave source may be used or separate phase-locked oscillators associated with each element.

Title: A valve in a paint spray gun
IPC: B05B7/24
Filed: 1981-04-30
Abstract: A needle valve and retaining nut assembly for controlling the flow of air to the horns of a paint spray gun comprises an annular retaining nut 12 which threadedly engages the gun body and has an internally threaded portion of its internal bore, and a needle valve member 18A formed in plastics material with an integral collar 18B which, on the side of the collar opposed to the valve member, adjoins a tang member 18E. A control knob 20 in its normal range of travel threadedly engages the retaining nut and is formed at its front end with a sleeve portion 22 in which the tank member is a push fit. The arrangement is such that when the control knob 20 is turned in the valve opening direction to beyond its normal range of travel so that the thread becomes disengaged from the nut 12 the collar 18B retains the needle valve member 18A', and control knob 20 captive in the gun. Also provided in the gun body is a cup shroud threadedly engaged with the gun body and arranged at its lower end for attachment of a paint cup. Gas under pressure flows from the gun body through a transfer chamber and a control valve controls the flow of pressurised gas from the transfer chamber to the paint cup. When it is open, the control valve communicates with a pressure relief valve so that gas cannot be delivered to the paint cup beyond its safe working pressure. <IMAGE>

Patent GB-2088779-A (GB)
Title: Characters-carrying printing wheel for impact printer
IPC: B41J1/30
Filed: 1981-10-14
Abstract: In a characters-carrying printing wheel for an impact printer, a metallic crown (1) carrying elastic arms (1a) provided with the characters (2) bears on a frusto-conical surface (7) of a central member (3) made of plastics material. This results in flexing of the crown (1), which is manufactured substantially flat, into a corresponding frusto-conical shape, the arms (1a) being however lifted into a common plane by a peripheral rim (3d) of the central member (3). Thus, should some of the elastic arms occupy a defective position out of the plane of the crown (1), being manufactured protruding on one face or the other of the crown, they are all brought back into a plane by the rim (3d) on which they rest in a preloaded condition owing to the frusto-conical shape of the crown (1) resting on the bearing surface (7) of the member (3). The rim (3d) is provided with radial grooves respectively engaged by the arms (3a), for lateral location of these arms and to prevent lateral movement thereof during acceleration and deceleration of the characters-carrying wheel during printing. <IMAGE>
