Patent GB-2109986-A (GB)
Title: Gyro amplifier
Inventor: PERRING DUDLEY
IPC: H01J25/02
Filed: 1981-11-13
Abstract: A gyro amplifier includes a waveguide (1), circular in cross-section, a solenoid (7) for generating an axial in magnetic field within the waveguide and an injector (8) for directing a hollow beam (4) of electrons, in the form of a cone, into the waveguide. The electron beam interacts in the waveguide with radiation having a circularly polarised electric vector. Such radiation is introduced into the waveguide by a coaxial transformation means (30) which converts incident RF radiation, having a linearly polarised electric vector, into radiation having a circular polarised electric vector. A relatively wide bandwidth can be achieved with this arrangement as compared with that achieved using the hitherto known technique involving combining two degenerate linear polarised modes. The transformation means may comprise the series arrangement of a rectangular-to-circular waveguide transformer (31) a Faraday rotator (32) and a circular polariser (33) (Fig. 4, not shown). <IMAGE>

Patent GB-2111774-A (GB)
Title: Current sensing device
Inventor: GRIFFITHS COLIN
IPC: H02H3/093
Filed: 1982-11-09
Abstract: Each of three saturable current transformers 10 produces an alternating secondary current whose magnitude is dependent upon the magnitude of the current flowing in a respective phase conductor 11 of a three phase electricity supply. A current-sensitive (e.g. bimetallic) switch 12 and an actuator 14 (common to all three phases) are connected in parallel across the output of each transformer 10. Under normal conditions, the secondary current is insufficient to open the switch 12 or operate the actuator 14. However, when the current in any one of the conductors 11 exceeds a predetermined fault value, the appropriate switch 12 opens in a time dependent upon the magnitude of the secondary current. The respective transformer 10 saturates, and the whole of the secondary current flows through the actuator 14 and causes the latter to operate switchgear (not shown) to interrupt the electricity supply in all three phases. <IMAGE>

Title: A method for the manufacture of porous, self-sustaining supporting means, mainly for electrodes of electric batteries, and the supporting means thus obtained
Inventor: TERZAGHI GIOVANNI
IPC: D06M10/00
Filed: 1983-03-04
Abstract: Porous self-sustaining supporting means, mainly for electrodes of electric batteries, are structured in the form of tubes, multitubular bags or sheaths, or of envelopes made of a synthetic, heat-shrinkable yarn. The shrinkage has been till now performed by convection or conduction heating, from which a partial degradation of the molecule ensues. This invention is related to a method for heating the yarn evenly and in depth, using infra-red rays with a limited wave length spectrum, which carry out the retraction applying the smallest amount of energy in the maximum absorption band. A minimal degradation is so achieved, together with a considerable saving of time, space and energy, obtaining a product with mechanical and chemical characteristics of high constant value.

Title: An expansion anchor
Inventor: LIMBRICK ROBERT WILLIAM
IPC: F16B13/04
Filed: 1985-02-28
Abstract: A unitary thick walled spacer S supports an anchor rod 15 for engagement in an expansion body 6. The tubular spacer S has a first part P of greater diameter than its remaining part P', with the part P' in slide fit engagement in the expansion sleeve 1, and the part P abutting, at its free end, the washer 17 and the head of the anchor rod 15. The annular shoulder M formed between the parts P and P' of the spacer S, is arranged, prior to use, a distance X from the expansion body 6. As clamping down is performed in a receiving socket, the spacer part P' slides inside the expansion sleeve 1 so progressively closing the gap X. The arrangement may be so designed that in any particular application, the shoulder M never (or at the most just does so) comes into contact with the expansion sleeve 1 to avoid loading the spacer S. <IMAGE>
