Title: Improvements in and relating to Thermographic Reproduction
IPC: G03C1/60
Filed: 1967-12-13
Abstract: 1,176,548. Thermographic processes. KALLE A.G. Dec. 13, 1967 [Dec. 15, 1966j, No.56640/67. Heading G2C. A thermographic process comprises reflex exposing to heat a material comprising a transparent natural fibrous support coated with a layer containing a diazonium compound or a quinone diazide but containing no coupling component to produce a positive destruction image which is opaque when viewed by transmitted light and a light image on a dark background when viewed by reflected light. The image may be fixed by uniform exposure to light. The heat-sensitive layer preferably contains an acid such as citric sulphosalicylic, tartaric or trichlorocetic acid (which releases acid gases on heating) and may contain a polymeric binder such as polyvinyl alcohol; the presence of an acid aiding the destruction of the natural fibres and thus the formation of the image. The imaged may be used as a master for diazotype process as the destruction image is opaque to ultraviolet radiation.

[Also in Division G3] The props of a longwall system are maintained in an ideal position e.g. at right angles to the seam, by means of corrective devices controlled by pendulum-type switches which in turn, are automatically set to corresponding ideal values by a command or pilot pendulum-type switch attached to a girder 3 laid along the floor of the longwall. The pilot switch comprises a plumb-bob 8a and switching element 136' which swing synchronously on changing the angle of incidence of the longwall working in front of one of two signal-associated orifices in order to activate a control system which acts on a piston and cylinder 5, 6 drive mechanism for restoring the axis of the switch housing to co-incidence with that of the bob's. The resultant pivotal movement of the housing shifts a contact mechanism which is built into the axle of rotation 7 and connected to the plurality of pendulumtype switches attached to the props (29, Fig. 5). The contact mechanism connects one signal duct out of a plurality of signal ducts with a source of compressed air in order to produce a corrective signal for setting the switches controlling the devices which alter the position of the props. For details of the control system, the specification should be referred to.

Title: Position memory system
Inventor: KELLY LEONARD
IPC: B07C5/36
Filed: 1968-12-31
Abstract: 1,212,120. Sorting ore photo-electrically SPHERE INVESTMENTS Ltd. Dec.31, 1968, No.61888/68. Heading G1A. Relates to a system for memorizing the size and position of ore fragments passing through a photo-electric inspection station for synchronized operation of a down stream sorting device. As the ore moves along a conveyer belt, it is scanned by a photo-electric device to produce a reflectance signal which is analyzed to determine various parameters such as lighter or darker than predetermined levels or changes from light to dark within a predetermined time. The signals produced are fed to eight modules of which one is seized when a rock is detected and, ignoring other rocks looks for the rock that seized it at appropriate points in each scan. The module integrates the signals corresponding to its rock until, when it detects the rock no more, it compares preselected integrated signals in a preselected manner to decide whether the rock is acceptable or not. Twenty air blast nozzles are arranged across a sorting zone at the end of the belt and associated with each nozzle is a shift register. If a module decides a rock should be rejected, it determines, from pulses synchronized with the scanning, which of the nozzles the rock will pass and sets a number of stages in the corresponding shift register equal to the number of scans on which the rock was detected. The set stages are shifted through the registers by pulses from a belt tacho-generator so that they actuate the appropriate nozzles as the reject rock passes. As soon as the module has made its decision and, if necessary, set the shift registers it is reset to lock on to another rock when required.
