Patent GB-2169255-A (GB)
Title: Device for propelling a vessel or a person
Inventor: SMITH PHILIP SYDNEY
IPC: B63H1/32
Filed: 1985-01-04
Abstract: This invention relates to reciprocating propelling means, (such as sails, paddles, flippers and oars) manually or otherwise motivated; that is, by mechanical means or by natural scientific means of wind, wave or water current. The propelling device (Figure 1) has two basic portions, a frame (11) and flaps (12). The frame portion 11 may be more or less rigid, but always more rigid than the flaps (12). The device may comprise a single aperture frame with a single flap or be of a modular nature with multiple frames and flaps, and may be planar (Figure 1) or three dimensional (Figure 6). Upon reciprocation of the vane, a large amount of thrust can be exerted in one direction by virtue of the flap(s) closing the aperture(s), with a very small amount of thrust in the other direction. Thus it serves the purpose of a non-rotating propeller for a person or a vessel. <IMAGE>

Patent GB-2220513-A (GB)
Title: Security enclosure
Inventor: MACPHERSON HUGH
IPC: G06F1/00
Filed: 1989-06-14
Abstract: A security enclosure is formed from layers of flexible material. One layer (11;18) carries a flexible semiconductive line (10,13) arranged to extend over the whole area of the enclosure. Any interruption of the line by unauthorised opening of the enclosure changes the resistance of the line and so can be detected by a monitoring circuit. Further, two layers (17) of semiconductive fibres also cover the whole area of the enclosure and are separated by an insulating layer (16). The length of the fibres is greater than the thickness of the insulating layer (16) so that if the enclosure is pierced fibres from one layer (17) will be forced into contact with fibres from the other layer (17). This will change the combined resistance of the layers and this can also be detected by a monitoring circuit. The two measures can be used separately. <IMAGE>
