Patent GB-2112971-A (GB)
Title: Data protection system
Inventor: BALDACHIN JONATHAN
IPC: G11B20/00
Filed: 1981-12-15
Abstract: A magnetic disk has a plurality of tracks (23,24,25 etc.) recorded thereon, each comprising a plurality of segments, each segment comprising an identifier (ID) followed by sense information, and being preceded by a synchronizing sequence (SYN). A stretch (23) of a track which has been fully written, including the whole of at least 1 synchronizing sequence, is read and inserted (at 24) into the sense sequence of a track written later. A further sense portion (25) of the recorded program compares stretch 23 with the check portion 24 when the program is run. This means that an unauthorised copy of the disk will not work, as stretch 23 and check portion 24 will not match. This is because disk copiers such as 'bit copiers' have to regenerate the synchronizing sequences afresh; a track cannot be simply copied directly onto another disk, as the copied sequence would either not join up or would overlap itself. <IMAGE>

Title: Gas turbine engine including a variable area nozzle
Inventor: MAGUIRE ADDISON CHARLES
IPC: F02K1/12
Filed: 1982-02-10
Abstract: Known variable nozzle actuating mechanisms are of complicated construction, which is acceptable where the devices are used on engines which power manually controlled aircraft. In such cases their operation can be monitored. The invention although usable on such engines, is particularly useful on engines which power pilotless vehicles i.e. missiles by virtue of its simplicity and therefore reliability. The variable nozzle (16) has flaps (18) which are held in a first throat constricting position by a knuckle mechanism (26). Opening of the throat is achieved by moving ram rods (48) to the left as viewed in the drawing, to straighten the knuckle mechanism (26) about pivot (36). Gas loads on the inner surfaces of the flaps (18) push the flaps outwards. At all operating positions of the flaps (18) except this fully open Position gas loads are transferred via the knuckle mechanisms onto the fixed cowl (12). Secondary flaps (20) may be included. <IMAGE>

Title: Controlling the molten metal level in DC or EM continuous casting
Inventor: TAKEDA SUSUMA
IPC: G05D9/00
Filed: 1982-11-16
Abstract: Sensing element (60, 62, 65) senses the level (61) of molten metal in the DC or EM casting apparatus and generates a signal proportional to the level sensed; the level signal is compared with a set point signal representing the desired molten metal level, an error signal is generated for differences between the signal representing the level sensed and the set point signal, and the flow of molten metal to the DC or EM casting apparatus is controlled by a control assembly which operates in response to and in a manner proportional to the error signal. A master controller (80) holds the set point signal and supplies it to individual local controllers (71) each of which by way of associated actuator (56) regulates molten metal flow to the associated casting zone. Melt flow is regulated by a pin or plug (40) which is raised or lowered directly or indirectly by the rotation of a cam shaped like an Archimedes spiral to ensure proportional regulation. <IMAGE>
