Title: Improvements in and relating to flexible barriers
Inventor: HALE PETER THOMAS
IPC: E21B17/20
Filed: 1983-01-26
Abstract: A flexible barrier, such as a high pressure flexible pipe, for containing pressurised fluid, and in particular diphasic fluids, comprises a first layer of polymeric material which in use of the barrier is arranged in proximity with the fluid to be contained, and a second layer which has been formed of a polymeric material of a kind incorporating an additive which when removed results in a substantial increase of the permeability of the material of the second layer in comparison with that of the first layer.
Patent GB-2115946-A (GB)
Title: Improvements in or relating to visual display apparatus
Inventor: SPOONER DR ARCHER MICHAEL
IPC: G02B26/12
Filed: 1983-02-02
Abstract: The invention provides head- coupled area-of-interest visual display apparatus particularly for ground-based craft-flight simulators. The apparatus provides binocular, pseudo-collimated vision of a display, projected onto the inside of a part-spherical shell which carries a concave retro-reflective screen and surrounds the pilot. The displayed scene covers an area of interest centred upon the pilot's line of view. The image generator used may be of the computer generated image, laser-scanned model or closed-circuit television type. For the pseudo-collimated display, the same image is projected for left and right eyes from points on a pilot's helmet above the pilot's eye positions. Line scan apparatus is mounted in the pilot cockpit. Line image transmission is by fibre-optic light guide ribbon and two such light guide ribbons are used to restrict impairment of the image by fibre fracture. Common frame scan apparatus is mounted on the pilot's helmet. Sensing means detect the pilot's head/helmet movement to permit voluntary scanning of a wide angle of simulated pilot view from the craft.

Title: Self-cocking shutter for a photographic camera with a flash firing means
Inventor: BETHMANN HEINZ G
IPC: G03B9/70
Filed: 1983-09-30
Abstract: In a self-cocking shutter mechanism a shutter cocking member 2 activated manually by button 2a in direction A moves a shutter blade 4 to a cocked position in which the blade is held by a holding element 8. By means of a pawl 3 mounted thereon, the shutter cocking member 2 tensions a striker spring 7 on which is arranged an ignition hammer 7a associated with a piezoelectric generator 11 as well as a striking hammer 7b associated with the, holding element 8. When the shutter blade 4 has assumed its cocked position, the cover blade 5 has been pivoted out of the taking ray path and the striker spring 7 has been tensioned, the pawl 3,3a releases the striker spring 7 causing the ignition hammer 7a to strike the piezoelectric generator 11 which produces a pulse for firing a flash lamp. The striking hammer 7b (shown in Fig. 2) continues to move and strikes against the holding element 6, thereby releasing the shutter blade 4 for exposure - the predetermined associated between flash firing and shutter release ensuring a reliable synchronisation of these two functions. <IMAGE>

Title: Anti-drill barrier structure for safe or strongroom doors or walls
Inventor: SKELTON ANTHONY JOHN
IPC: F41H5/02
Filed: 1985-01-25
Abstract: The barrier comprises a closely- spaced array of cemented carbide pins 1 or balls 4 force-fitted into interference holes in a steel plate 2, and aligned with the anticipated direction of attack. The force-fitting of these hard elements makes them very difficult to remove and also pre-stresses them in compression, so that the net (tensile) failure stress is increased. Carbide-tipped drill-bits penetrate partially into the steel surrounding the hard elements whereupon the flanks of the carbide inserts on the drill tip impact the hard elements and are broken off.   <IMAGE>

Filed: 1986-03-14
Abstract: The security fastening comprises two bars joined together with a thread, which when placed between two fixed cups, i.e. one on a fixed panel, and one on a sliding door, clamps the door into the door jam, the thread serving to adjust the length of the bars, enabling the bars to be removed from the cups when screwed together, thus being able then to open the door. To lock the door, simply close the door, place bars between cups, and extend the length of the bars into cups, by relatively rotating.
Patent GB-2174813-A (GB)
Title: Waveform generator for nuclear magnetic resonance apparatus
Inventor: WILLARD REGINALD ALFRED
IPC: G01V3/14
Filed: 1986-04-29
Abstract: Nuclear magnetic resonance is excited in surrounding fluids, e.g. about a borehole or body cavity, by pulsing a first winding which with a capacitor forms a resonant circuit. In order to observe signals induced by NMR in the winding between pulses, the pulses are given an envelope which rises linearly to a peak and then immediately decays linearly to zero. A waveform generator generates bursts of constant amplitude oscillations having a 180 DEG  phase change at the centre of each burst. When such bursts are applied to the resonant circuit by way of a drive amplifier and a second winding wound over the first winding, the required envelope is generated in the first winding. The duration of one pulse portion, and the amplitude of the same or other pulse portion, may be adjusted. A third winding wound over the first winding is connected to a switched attenuator operated to ensure that residual situation in the first winding is rapidly removed. <IMAGE>
