Title: Protecting and checking documents
IPC: G07D7/0047
Filed: 1982-06-03
Abstract: In a method for the protection and checking of documents protected against imitation, falsification and misuse, the document is provided with an integrated circuit with a memory which is inaccessible from the outside. Use is made of pairs of algorithms or allocated codes based on trap-door functions, one of which is kept secret whilst the other does not require to be kept secret. Information is coded by means of the algorithm kept secret or the code allocated to it. The coded information is decoded using the algorithm or code which does not require to be kept secret. The decoded and uncoded information is compared, and the result of the comparison indicates the validity of the document. In order to protect the document, the algorithm kept secret or the associated code is stored in the document memory which is inaccessible from the outside. For the check a random number is coded by means of the algorithm kept secret or the allocated code in the integrated circuit for the document. The coded random number is decoded by means of the algorithm which does not require to be kept secret, or the associated code, and compared with the original random number.

Title: Cable anchorages
Inventor: CROWNSHAW JOHN CHARLES
IPC: G02B6/44
Filed: 1982-06-15
Abstract: Helically applied armour wires (1) of a cable or the like are anchored to a plate (3), for attachment to a jointing chamber or repeater, for example, by gripping between an inner member (6) and an outer member (7). The outer member is longitudinally split such that axial movement of a locking collar (8) during fastening thereof to plate (3) causes radial movement of the outer member (7) towards the inner member (6) for gripping the anchor wires (1) therebetween. Due to the matching tapered faces (10) of the outer member (7) and the locking collar (8) increased load on the armour wires increases the gripping force effective thereon, thus minimising cable elongation and, for example, possible damage to optical fibres contained therein, The faces of the inner and outer members are suitably machined to ensure gripping of the anchor wire therebetween. <IMAGE>

Title: Rolling key clutch
Inventor: BAMBERGER ALFRED
IPC: B30B15/28
Filed: 1982-09-03
Abstract: The invention provides for an additional finger (5) engageable with a driver (7) of the rolling key (29), said finger (5) being located on an angularly movable bush (1). There is also provided a bearing ring (10) which is provided with a recess segment (17-18) into which the driver (7) extends. When said clutch actuating mechanism is disengaged with the drive motor at a standstill, the driver (7) takes up a position under spring-loading in which it bears against one edge (17) of said recess segment and sets the rolling key in its coupling position. Subsequent energisation of the drive motor will then only drive the shaft and the rolling key until the rolling key driver (7) comes to rest against the additional finger (5) of the bush (1). The rolling key is then turned back into its released position, without movement on the part of the machine. In that manner, accidents and breakdowns within the tooling area as referred to, are also avoided in the event of unauthorised actuation of the engagement/release arrangement. <IMAGE>

Title: Method of and device for metering bulk material
Inventor: MEIER KARL
IPC: B27N3/14
Filed: 1983-08-11
Abstract: Bulk material containing lignocellulose, such as wood chips etc., particularly for cement-bound wood particle boards, is controllably discharged from a bin (1), subjected on a premetering belt (5) to a first metering by volume by skimming roller (6) and weight by load cells (8) and is spread onto a fine metering belt (10) where it is metered a second time by volume by skimming roller (11) and weight by load cell (13). The weight-dependent pulses of measuring device (8) are used to control the discharge speed of the bin discharge belt (2) and the weight-dependent pulses from the measuring device (13) are used to control the speed and thus the bulk quantity of the premetering belt (5). This results in the optimally uniform spreading of the bulk material according to the height and width of the preform and thus in optimally uniform finished hardboards. <IMAGE>

Title: Mine chock construction
Inventor: THOMPSON JOHN DOUGLAS
IPC: E21D15/48
Filed: 1985-06-07
Abstract: Chockpieces for use in constructing mine chocks are fabricated each from two mutually separate timber blocks 10 which are glued between laterally spaced timber plate members 12. Each block is made from two sub-blocks 10A and 10B glued together. In use, the blocks are loaded end-on to the timber grain to attain high early strength, and the plate members are disposed with their general plane upright. The upper and lower block faces are recessed by distance S with respect to the adjacent plate member edge faces so that early local indenting of the plate member edges under loading effects interlocking of the chockpieces. The chockpieces are tension-banded by band 14 at each end. The banding serves to retain the plate members with the blocks so to extend the stabilising function of the plate members on the mine chock during the rupture phase. <IMAGE>
