Title: Linked computer system
IPC: G06Q10/00
Filed: 1979-07-10
Abstract: In a linked computer system, information is stored in a plurality of units, any one of which is operable to recall information from its own store 14 or from that of another unit. The units are linked in a ring and each unit is conditioned to receive and to transmit a system free message which is circulated around the ring so that only the unit in possession of the system free message can send an enquiry message around the ring in order to obtain the response message from one of the other units. The units can distinguish errors and also transmit the system free message in the event of an error. Local information retrieval is also possible from each unit. <IMAGE>

Title: PSK Demodulator
IPC: H04L27/227
Filed: 1979-07-17
Abstract: A demodulator for demodulating a phase modulated signal produced by phase shift modulation of a carrier at N = 2<M> phase levels equally distributed by 2 pi /(N+1), which correspond to M-bit words of a digital modulating signal, comprises two phase locked loops receiving the phase modulated signal. A first loop 81 is locked to a frequency equal to (N+1) times the carrier frequency. A second loop 82 is locked to the carrier frequency and produces a signal at the carrier frequency which is phase shifted relative the reference phase by the variable residual phase modulation. A carrier shaping circuit 9 eliminates the residual phase modulation produced by the second loop 82 under the control of the signal produced by the first loop 81 to provide a pure signal at the reference phase and at the carrier frequency for discriminator 5. <IMAGE>

Title: Simulated Stained Glass Windows
IPC: B44F1/06
Filed: 1979-07-23
Abstract: A method of producing multi- coloured glass windows involves the application of coloured inks 14 to a pane of glass 12 using a screen printing process and protection of the printed surface either by means of lacquer or varnish 16 or a second sheet of glass which may to advantage be spaced from the first to form a double-glazed window unit. Modifications of the basic design involve the use of opaque inks to define lines or areas within the window so that when the window is illuminated from one side and viewed from the other the coloured areas are brought into relief by the dark black lines or regions of opaque ink. Further modifications involve the sticking of strips of lead along the joins between the different coloured regions so as to simulate leaded light windows. <IMAGE>

Title: Method for vulcanizing an insulating layer of an electrical cable
IPC: B29C48/91
Filed: 1978-12-21
Abstract: A method for vulcanizing an insulating layer of an electrical cable. In a continuous process for manufacturing an electrical cable, which comprises an electrically conductive non-metallic layer extruded outside and preferably simultaneously with an electrically insulating layer, a method of vulcanizing the insulating layer comprises passing the cable (3) through a gas-filled pressure chamber (1) in which it is supplied with heat for vulcanizing the insulating layer, the heat being supplied completely or partly in the form of heat due to electrical resistance heating generated by electrical energy transferred to the conductive layer. In one example, the electrical energy is transferred to the conductive layer by means of at least one electrode (2, 4, 5 or 7 to 10) making contact against the layer. Alternatively, the electrical energy could be transferred in a capacitive way, or magnetically by generating eddy currents in the conductive layer.

Title: Improvements in hydraulic control apparatus for controlling the operation of mine roof support props
IPC: E21D23/26
Filed: 1980-04-08
Abstract: Hydraulic control apparatus for mine roof support props includes a manually-operable main valve (11) which can be set to selectively connect fluid pressure and return lines (P, R) to the working chambers (10', 10'') of at least one associated prop (10) to extend and retract the prop. A pressure-relief valve (12) is connected to the chamber (10') which effects extension of the prop. The relief valve (12) is capable of passing the same quantity of fluid as the main valve (11) and operates at a pressure only slightly greater than the setting pressure of the prop. An automatic setting arrangement (15, 24), connects the prop chamber (10') to the pressure line (P) automatically when the chamber pressure rises beyond a threshold level and the prop is in contact with the roof. This ensures that the correct setting pressure is established whether or not the main valve (11) has disconnected the pressure line (P) from the prop chamber (10'). The pressure line is disconnected at a chamber pressure only just below the response pressure of the relief valve (12). In an alternative embodiment the relief valve (12) is automatically set to respond to a significantly higher pressure whilst the prop (10) is actually being set by the main valve (11) and reverts back to its normal response pressure once the prop (10) has been set. <IMAGE>
