Abstract: 607,395. Feeding match stock strips from stacks. LANGHAM, C. A., and MELLAND,. F. N. S. Feb. 1. 1946, No. 3282. [Class 117] In the manufacture of booklet matches the match stock strips, of wood veneer or cardboard, are fed singly from the base of a hopper by means which include an ejector plate reciprocated across the base and belts engaging resiliently the edges of the strips through apertures in the sides of the hopper and being driven in synchronism with the ejector plate movement to feed the strips downwardly. As shown, the match stock strips 5 are stacked in a hopper 1 which is open at the bottom and is mounted above a horizontally-slidable base plate 8. The plate, which is reciprocated by means including a connection to an oscillating lever 17, is provided with a block 88 formed with grooves between ribs 10 which co-operate with complementary grooves and ribs in the bottom of the rear plate 1a of the hopper whereby a match stock strip 5 is removed from the hopper during each forward movement of the plate 8. The strip is prevented from return by means of a carriage 81 carried by pivoted levers 77 and provided with a serrated gripping blade 82. The plate 8 is provided with a toothed rack 20 meshing with a spur wheel 21 on a shaft 22. The shaft carries an eccentric 24 having a rod 25 connected adjustably to a lever 30. The lever is pivoted on a shaft 34 and carries a pawl 35 engaging a ratchet wheel 36. The wheel 36 and a belt pulley 43 are fast on the shaft 34. An endless belt 49 passes over the pulley 43 and an upper pulley 50, and engages the edges of match stock strips through openings 54 provided in the side of the magazine. Similar pulleys and belts are provided on the opposite side of the hopper. Both belts are connected operatively by means which include gear wheels 39a. The arrangement is such that as the plate 8 reciprocates the belts move step by step to feed the metal strips 5 downwardly. The hopper 1 may be fitted with a detachable auxiliary hopper 70. Electric means may be provided to give warning or to stop the mechanism when the hopper is almost empty. As shown, a bell crank lever has an arm 90 engagable by the match strips and normally positioned so that contacts 93, 94 are opened. When the strips have passed the arm 90 the contacts are closed to complete a circuit for giving the warning.

Title: Core column articulating unit
IPC: G21C5/08
Filed: 1978-10-04
Abstract: For providing between the ends of two bored blocks, stacked in a column of a nuclear reactor core, a connection which is substantially sealed while yet permitting limited articulation, a pair of tiles 16, 17 are interposed between the blocks. Each tile, apertured in register with the block bores, engages the end of one of the blocks sealingly and without relative movement, and the required articulation is provided between the tiles, whose mutually engaging faces are made slightly bowed and are shaped to accommodate a sealing ring 25 (split into quadrants) between them. Because relatively small, both tiles of a pair can be made from a single piece of (e.g. graphite) material, with the same tools at the same time; and manufacturing tolerances (and sealing imperfections) may thus be minimised. The tiles of a pair can be factory assembled and temporarily pinned together for handling as a single unit in building the core. <IMAGE>

Patent GB-2018477-A (GB)
Title: Memory protection
IPC: G06F12/14
Filed: 1979-03-21
Abstract: In a digital computer data may be protected to prevent central processor unit (CPU) access to invalid data and data corruption by overwriting. The time overhead for software enforcement of data protection is avoided by a protection circuit (16) which sets a status flag (17) to inhibit CPU (10) access to a main memory (11) location if an associated protection code held in a region (15) of main memory has not previously been set to allow such access. When a process is halted in this way a new process as defined by pointers stored in memory (21) is selected by a scheduler (22), the CPU environment being transferred to a memory font (23) for subsequent reloading when that process is next selected. A coding circuit (19) updates the protection codes after CPU access to main memory. In this way correct synchronization of processes is enforced without additional software interlocks. <IMAGE>

Patent GB-2061583-A (GB)
Title: Self-priming interlock/warning system
IPC: B60R25/10
Filed: 1979-07-27
Abstract: The output of an interlock/warning system can be inhibited so that an abnormal condition can be permitted to exist without an interlock/warning output being generated. Once a condition of normality has returned and remains in existence for a predetermined period of time (timer A) the "Inhibit" is removed automatically from the output so that any subsequent abnormal condition will give rise to an interlock/warning output. An abnormal condition can be rendered ineffective within (say) 7 seconds of its existence (timer B) by the application of a "cancel" signal. Failure to apply a "cancel" signal (within the 7 second period) once an abnormal condition occurs will result in an interlock/warning output being generated for a predetermined period (timer C). One application is that of a vehicle alarm - where the use of seat switches enables the abnormal (occupied) condition to exist without sounding a warning once a cancel signal has been applied. Once the vehicle is left unattended with doors/bonnet/boot closed (normal condition) for in excess of a predetermined time period, the inhibit is automatically removed from the output so that any subsequent abnormal condition (door opening, etc) will give rise to warning output (horn, ignition immobilise). <IMAGE>

Title: Method and installation for manufacturing multilayer pipes
IPC: B23K1/14
Filed: 1979-06-27
Abstract: According to a known method for manufacturing such pipes which are used particularly as brake lines in motor vehicles, a steel strip provided with a copper coating is wound transversally and in a continuous manner so as to obtain an endless multilayer pipe which is then submitted to a heat treatment. According to this continuous heat treatment, the cold pipe is brought and kept at 1370`K. The copper coating melts and the different layers of the pipe are welded together. The quality of the pipe then obtained depends on several conditions which are difficult to satisfy; for example, this method requires a high mastery of the technic of production, perfectly adjusted machines and a steel strip with small thickness tolerances so as to avoid considerable manufacturing difficulties. In order to avoid too much production waste, the heat treatment of the multilayer pipe is carried out in two steps. Immediately after the formation of the pipe and combined with the first heating step, a final annealing temperature of 1200`K in order to eliminate the stress and to obtain the welding during the second heating step.
