Title: A method of moulding a data carrying element
IPC: B29C35/00
Filed: 1981-02-13
Abstract: A method of injection moulding an acrylic resin into data - carrying elements such as phonograph records or video discs is disclosed.

Styrene is also mentioned as a moulding material. <IMAGE>
Patent GB-2074959-A (GB)
Title: Track tensioning apparatus
IPC: B62D55/08
Filed: 1979-12-03
Abstract: A continuous track assembly (12) has a frame (16) and a first element (18) pivotally connected to the frame (16). A second element (20) is pivotally connected to the first element (18). Each element (18, 20) has a rotatable wheel (22, 24) about both of which a track (30) is positioned. The wheel (22) of the first element (18) is rotated by power and driving apparatus (36, 44) in an associated work vehicle (10) to drive the track (30). Tension in the track (30) is maintained at a preselected level by apparatus (50) which moves the second element (20) relative to the first element (18) to position the wheels (22, 24) against the track (30). The wheels (22, 24) are freely pivotally movable as a unit to enable the track assembly (12) to readily adapt to its environment and maximize tractive effort. Maintaining the desired track tension substantially overcomes problems associated with a track which is too loose or tight which can result in slipping or damage to the track assembly (12).

Title: Torrefied cereals for use in the feeding and veterinary treatment of ruminant animals
IPC: A23K1/14
Filed: 1981-05-15
Abstract: A veterinary substance, primarily for animals of the ruminant kind, consists of torrefied cereal grains, preferably barley, in the expanded whole grain state. This substance is particularly useful for treating or preventing bovine acetonaemia or ovine pregnancy toxaemia. Torrefied cereal grains in the expanded whole state can also be used beneficially in the diet of healthy ruminant animals. As a veterinary substance or as a feed product, the torrefied cereal grains are preferably provided with a palatable coating, for example a substantially non-tacky molasses based mixture, which is soluble in, or at least permeable to, the rumen liquor of the animal. The torrefied cereal grains can also be used to administer to ruminant animals nutritional and/or medicinal substances which act only on the abomasum and small intestine, the substances conveniently being carried beneath the palatable outer coating in an undercoating which is substantially insoluble in the rumen liquor but will permit absorption of the rumen liquor by the grains, and which dissolves in the abomasum or small intestine.

Title: Method and apparatus for preventing unauthorised recording of source material (e.g. a gramophone recording)
Inventor: KING JAMES BERTRAM
IPC: G11B27/28
Filed: 1981-08-06
Abstract: A system for preventing unauthorised recording of source material comprises putting onto a source signal, for example a gramophone recording, a coded signal and including in a tape recorder a detector circuit to mar or inhibit recording only of that source signal, the coded signal being such that it does not significantly detract from the source material quality when played through normal equipment. A detector 8 is activated by the coded signal on attempted recording (and/or on replay) and may inhibit an amplifier 5 or activate a spoiler oscillator 10 which adds a spoiling signal to the input through a mixer 6. The coded signal may be a discrete signal comprising a burst of fixed frequency and may be recorded in digital form (e.g., as an 8 bis code word). <IMAGE>

Title: Adapter for video cassette
Inventor: D ALAYER DE COSTEMORE D ARC ST
IPC: G11B25/06
Filed: 1982-12-01
Abstract: The adapter 26 allows a miniature cassette 16 to be played in conventional video apparatus. The adapter 26 has the outer shape and dimensions of a standard, large size video cassette and has a cavity 30 in one face for receiving a miniature cassette 16 having spools 20A, B and recording tape extending therebetween normally in a small loop. Guide rollers 46A, B are mounted on pivotable arms 52A, B movable by a motor in the adapter for forming a large loop of the recording tape of a miniature cassette in the cavity with a section of the large loop extending along a straight elongated path along the front face of the adapter. Hubs 80A, B are rotatably mounted in the adapter for access through a face thereof by and for cooperation with spindles of a video apparatus and the hubs rotate through gearing the miniature cassette spools 20A, B to transfer recording tape along the path of the large loop. The motor is automatically or manually operated, eg by push button 48. At least one spool 20A, B is rotated during the retraction of the arms 52A, B so as to take up slack. The adapter includes a spring biased safety means consisting of a block 200B slidable between two positions which represent the retracted and extended positions of the arms. Insertion of the adapter into the video apparatus when the arms are still retracted is prevented by a catch 21 which, when the arms reach their extended position pivots out of path of block 200B to allow insertion. A switch 50 disposed at bottom of cavity 30 and actuated only when cassette is correctly mounted in cavity, forms part of the supply circuit of the motor and so disables the motor unless the cassette is correctly positioned. Block 200B opens switch 250 disposed in the motor circuit when the adapter is in the video apparatus so disabling motor and preventing movement of the arms from the extended position. <IMAGE>
