Patent GB-2336472-B (GB)
Title: Frequency selective radar absorbent structure
Inventor: MACKAY ANDREW JAMES
IPC: H01Q17/00
Filed: 1992-06-22
Granted: 2000-03-29
Abstract: The structure 10 has a layered construction. It includes a conducting layer 12, a central layer 14 of thickness h and a patterned conducting layer 16 of thickness g, these layers being successively disposed. The patterned layer 16 has an array of slots such as 18. In the central layer 14, the product of propagation loss/unit length and thickness h lies in the range 0.005 to 0.1. The structure is able to absorb incident energy by means of the excitation of surface waves in the substrate layer 14. This enables the dielectric layer to be thin.

Title: Optical transmission system
Inventor: HIRST IAN JOHNSON
IPC: H04B10/00
Filed: 1993-04-20
Granted: 1996-12-04
Abstract: An optical transmission system comprises amplified forward and return paths between a local station and a remote station. Each amplifier of the forward path has an attenuated loopback coupling its output to the return path. Frequency modulated supervisory signals generated at the local station are returned via the loopbacks. These signals are analysed e.g. by Fourier analysis to obtain a measure of the performance of each amplifier. The system may also be employed for the location of fiber breaks.

Abstract: PCT No. PCT/EP94/03211 Sec. 371 Date Mar. 27, 1996 Sec. 102(e) Date Mar. 27, 1996 PCT Filed Sep. 19, 1994 PCT Pub. No. WO95/09263 PCT Pub. Date Apr. 6, 1995A dispenser container for a paste is provided. The dispenser container is formed from a cylinder open at one end for holding the paste, a displaceable tightly fitted follower plate means is arranged at the open end of the cylinder and a dispenser for transporting the paste from the container is arranged to cooperate with the follower plate. A motor and transmission are mounted near the center of the follower plate and has a shaft which extends through the follower plate and has mounted thereon a multiple blade stirrer. The stirrer rotates in the paste below the follower plate. The dispenser removes the paste from the container at a position away from the center of the follower plate in an area below which the multiple blade stirrer rotates. The multiple blade stirrer by rotating in the paste lowers the viscosity and permits the paste to be more easily transported from the container by the dispenser.

Title: Moulding tyre treads - using forces produced by elastic deformation of mould sections
Inventor: PACCIARINI A
Filed: 1972-10-20
Granted: 1980-04-21
Abstract: Relief patterns are moulded on the tread strip of a tyre during the vulcanisation of the tyre in a mould, the pressures produced by a vulcanising fluid being exercised inside the tyre in the mould, which has two sections disposed for pressing the sidewalls, and a number of sections disposed for pressing the tread strip. When the pressure of the vulcanising fluid acts inside the tyre, the forces produced by the forced elastic deformation of one or more mould sections are applied to the mould segments, these forces opposing radial movements of the segments, caused by the pressures exercised inside the tyre. Specif the forced elastic deformation is obtd by means of an interaction between several mould ports when the mould is in the closed posn. The forces are produced by the forced elastic deformation of an annular section surrounding the segments.
