Title: Interactive Video System
IPC: G09B5/06
Filed: 1981-01-15
Abstract: An interactive video production system and method is provided in which an analog video storage means 16, such as an analog video tape recorder, capable of retrievably storing a composite analog color video signal, such as a composite analog video signal having red, blue and green analog video components and having an associated video information content, retrievably provides this composite analog color video signal as a video output signal at a real time video frame rate for digital video image processing in a 4:3 aspect ratio configuration of active pixels on a real time interactive basis so as to enable the video characteristics of the active pixels forming each video frame to be interactively controlled during video production. Decoding means 20 are provided for decoding the composite color video output of the analog video storage device into red, blue and green analog video components before provision to the digital video image processor 12. The digital video image processor thereafter provides the digitally processed red, blue and green video component signals as separate processed analog signals which are subsequently encoded 36 and combined into a processed composite color video analog signal.   <IMAGE>

Patent GB-2099756-A (GB)
Title: Telephone debit card
IPC: G06K19/14
Filed: 1981-06-09
Abstract: A debit card, such as may be used for operating a public pay telephone consists of a card of a plastics insulating material having embedded in it a number of optical fibres (1) each of which extends between two edges of the card. The fibres are "scrambled" to improve security, and each terminates at one end at a portion (1-10) of the card which is punched out when a unit is used up. There is also a validation fibre (2), which is also broken when the last unit is used up. When the card is read it is not accepted as valid unless this validation fibre (2) passes light. Finally there is a set of other fibres (3), also "scrambled" to convey other data such as unit value. The basic principle can be extended to identify cards or credit cards, in which case no punching out is called for. <IMAGE>

Title: Improvements in and relating to sealing structures
IPC: F16J15/02
Filed: 1981-07-31
Abstract: A sealing structure includes a tubular member 11 and a cylindrical member 12. The tubular member 11 has an annular step 16A on its outer surface. The cylindrical member 12 slides onto the tubular member in such a manner that an end of the cylindrical member is received by the step 16A. The cylindrical member 12 is bevelled along the inner edge of that end to form an annular space 31 of triangular cross- section adjacent to the inside corner of the step 16A. Two shims 22, 23 are placed between the end of the cylindrical member 12 and the step 16A of the tubular member 11, the shim 23 extending into the annular space. An annular sealing member 32 is fixed to the shim 23 and arranged within the annular space 31. The sealing member 32 has such a cross-sectional area that when the cylindrical member 12 approaches the tubular member 11 until the shim 23 abuts both members, the sealing member is deformed to contact both members throughout its length. <IMAGE>

Title: Brake actuator; wear adjustment
IPC: F16D65/18
Filed: 1982-05-21
Abstract: An actuator-adjuster mechanism (10) for an aircraft multi-disc brake has an actuator mechanism (20) and a tubular member (54) that engages a head (62) of a stem (40), the tubular member (54) having a plurality of openings (58, 58' . . . 58<N>) located at intervals along its axis and the head (62) acting to sequentially expand the material between the openings (58, 58' . . . 58<N>) to adjust for disc wear. After the head (62) has passed an opening (58, 58' . . . 58<N>), the material contracts to a neck down diameter that is substantially equal to the initial diameter of the tubular member (54) to constrain the tubular member (54) with respect to stem (40). Thereafter, should a force be applied to an end cap (28) from thermal expansion or axial inertia forces during aircraft manoeuvres the actuator mechanism (20) is held in a constrained rest position. The holes (58 . . .) may be circular - after expansion, oval; or e.g. rectangular (Figure 4). <IMAGE>

Title: Antennas
Inventor: JAMES JAMES RODERICK
IPC: H01Q13/24
Filed: 1983-08-10
Abstract: An antenna for detecting buried objects 7, eg plastic mines, by back-scattered radiation comprises a brush-like bundle 5 of flexible fibres of dielectric material projecting from a block 4 of dielectric material matched into a waveguide 2. In use the bundle 5 contacts the ground, thereby preventing an air-gap between radiation source and ground-surface. This reduces the impedance mismatch at the surface due to such a gap and so promotes penetration of the radiation rather than reflection thereat. <IMAGE>
