Title: Mobile communication systems
IPC: H04M3/00
Filed: 1972-10-18
Abstract: 1408614 Mobile telephone systems WESTERN ELECTRIC CO Inc 18 Oct 1972 [22 Oct 1971] 47894/72 Heading H4K A communications system serving both normal mobile telephone traffic and so-called dispatch mobile traffic, in which normal mobile telephone traffic is served on an immediate service basis and in which the dispatch mobile traffic is served on a guaranteed service basis involving a queuing system, includes an arrangement whereby initiation of service to a dispatch call is delayed for at least a predetermined time if less than a predetermined number of communications channels are free, the arrangement preventing the dispatch traffic from monopolizing the communication channels during high load periods.  The network described utilizes arrangements disclosed in Specification 1,369,017, which describes a high capacity mobile communication system wherein communications channels are flexibly assigned throughout the system. The following refers to the incorporation of dispatch type traffic into the system. The type of dispatch traffic concerned is that in which a number of stationary dispatchers wish to communicate with respective groups of mobiles. Each dispatcher has his own line, e.g. 117 or 118 &c., connecting him to the mobile switching central office shown, each line bearing an index which identifies the dispatch in question. Requests for service from the dispatchers are fed to a queueing buffer 119, which may be of the type disclosed in Specification 899,230, from which they are read out in order of arrival at a fixed rate, the dispatcher being notified at the time of read out. The read out is governed by a periodic Demand signal on wire 123 which is normally fed via gate 127 to the pulse readout input of the buffer. If, however, more than K of the communications channels 112-115 are in use the demand signal is blocked at gate 127 and passes via gate 124 to a time delay device 125 which delays the demand signal by an interval T. During this time the system can deal with any calls for service associated with the normal mobile telephone service traffic that  may arise. If all communications channels are in use the demand signal is blocked at both gates 124 and 127 because logic circuitry 108, 116 both produce logic O outputs. The logic circuitry 108, 116 which determine respectively whether at least one and K or more communications channels are free may be embodied as a symmetrical switching network. It is assumed in the arrangement that mobileto-dispatcher requests are relayed back to the dispatcher, whereupon to establish a call the dispatcher must proceed as he normally does to make a connection. Connections between mobile telephone subscribers, and between mobile telephone subscribers and subscribers on the public telephone system are completed in known manner. Only if no communication channel is available does the system issue a reorder signal to a mobile subscriber or to a public telephone subscriber attempting to contact a mobile.

Filed: 1975-12-06
Abstract: 1473267 Mining machines; dust suppression means HAYDEN NILOS-CONFLOW Ltd 6 Dec 1975 50154/75 Heading E1F A mining machine 3 has a control valve 5 which opens at a predetermined pressure in a hydraulically powered haulage 7 to supply dust suppression water to spray heads 2A, 2B. When the machine is idling with no load on its cutting heads 3A, 3B, the valve member 16 of the control valve is held against its seat 14 by water pressure from inlet 9 through the bleed 18 and a spring 15, and a pilot valve 21 having a piston 22 is held in a closed position by an adjustable coil spring 24 since the hydraulic pressure in the haulage 7, which is transmitted by a pipe 13 and passages 32, 33 to a cylinder 23, is insufficient to move the piston 22 against the loading of the spring 24. When the machine is cutting coal, the hydraulic pressure in the haulage 7 is great enough to cause the piston 22 to move, so removing the pilot valve 21 from passage 19. Water in cylinder 17 is thus able to flow away through passages 19, 20 to outlet 10 and causes the valve member to be moved off its seat 14 by the water pressure in the inlet 9. Water flows to spray heads 2A or 2B as determined by a changeover valve 6 in accordance with the direction of traverse.
