Title: Mobile radiotelephone communication system
IPC: H04W68/00
Filed: 1968-12-21
Abstract: In a radio-telephone communication system, subscribers connected to a wired network can communicate with subscribers having mobile radio telephone sets and can alert subscribers having mobile call warner sets via a radiotelephone base station which has means to store a plurality of call warner set numbers for transmission when a radio speech channel becomes free and means to alternately offer a speech channel for call warner and radio-telephone use. The system may be generally similar to those described in Specifications 1,190,865, 1,200,403 and 1,210,169. In one form in which the radio system covers an extensive area there are a plurality of base stations employing different speech channel frequencies and a common frequency service channel, all free mobiles housing to the common channel. Other forms not employing a service channel are suggested. In one form a free channel is marked with a tone and all radio-telephones standby in this channel, the channel being taken into use for a call in either direction. In another form the radiotelephones home on a channel marked for an incoming call and move to another marked channel for an originating call. A system employing radio operators and in which selection signals are broadcast over all free channels is also sugested. In any form dialling signals arriving from wired substation or from a radio-telephone mobile are entered in a register. If the number is that of a wired substation the call is established in known manner but if the register recognizes the call as a paging signal i.e. the number of a call warner it is forwarded and entered in an associative store at a base station. The write-in device of the store or the register incorporate a translator which determines the channel to be used and the number to be transmitted from the dialled designation, the call warner sets being distributed evenly over the speech channels and being each permanently associated with a single channel. Each channel is offered alternatively for call warner use and for full radio telephone use. When a channel is offered for call warner use the store is searched for call warner calls to be sent out over that channel and up to a predetermined number of such call warner numbers are transmitted over the channel before its again offered for radio-telephone use. The order in which free channels offered for call warner use are selected may depend on the chronological order of received call warner calls, on the quantities stored for each channel or may be chosen cyclically. When a channel is offered for radio-telephone use the call may be automatically interrupted after three minutes. If a call to a radio-telephone mobile arrives while no channel is free but a channel is in use for call warner service, the marker waits until this channel becomes free and only returns busy tone if the channel is not allotted for a terminating call, i.e. an incoming call can camp on a busy channel being used for call warner service.

Title: Drill boom structure
IPC: E21B15/04
Filed: 1969-03-11
Abstract: A support boom structure for a rock drill comprises a boom 10 swingable by hydraulic cylinders (not shown) laterally and vertically, a boom head 11 swingable by cylinder (not shown) via rod 17 about axis 15, a carrier 12 swingable by cylinder 19 about axis 16 which is perpendicular to axis 15, and a feed bar 13 slidable relative to the carrier by means of hydraulic cylinder 23. The carrier 12 comprises a casing 25 containing an hydraulic motor 30 and a plate 22 connected to journal members 24, 26 which are rotated relative to the casing 25 by the motor to pivot the feed bar about a third axis parallel to the feed bar axis. The motor comprises a piston 34 with a longitudinally splined rod 37 and a helically splined rod 32, which rods respectively co-operate with a longitudinally splined head 36 and a helically splined nut 33. The head 36 is fixed with respect to the casing 25 and the nut is mounted in one end of a rotatable driving member 41 which at its other end engages with the journal 24. Hydraulic fluid fed to either side of the piston 34 displaces the piston and thus effects rotation of the feed bar with respect to the casing 25. A lock valve 50 maintains the feed bar fixed with respect to the casing 25 until fluid is fed via conduit 4811 or 4911, valve 52 or 51 and conduit 481 or 491 to move the piston 34. During piston movement the other conduit 491 or 481 is connected via valve 51 or 52 and conduit 4911 or 4811 to a sump. Flow of fluid in conduits 4811, 4911 is controlled by a four way valve (not shown). In an alternative embodiment (Fig. 5, not shown) the carrier 12 is positioned with the axes of the boom and the axis 16 lying in a vertical plane. A further embodiment includes a telescopic boom and the feed bar in this embodiment can be adjusted out of parallel alignment with the carrier by means of piston/cylinder (61), the feed bar being pivotally connected to the rear journal member (26), and yet another embodiment (Fig. 9, not shown) includes a frame (60) mounted on a first carrier (62) similar to carrier 12 and a second carrier (63) parallel to the first carrier and mounted on the frame. The feed bar is mounted on the second carrier.

Title: Pattern dyeing of textile materials
IPC: D06B11/00
Filed: 1975-02-28
Abstract: The work is carried out with at least one row of dye nozzles which extends transversely to the direction of movement of the sheet-like textile structure, which can be a web of carpet material, pressurised jets of dye liquor issuing continuously from the dye nozzles. Each jet of dye liquor is directed either onto the sheet-like structure or away from this according to the pattern to be produced and according to the speed of movement of the sheet-like textile structure. By means of data blocks with pattern data, the selective deflection of each of the jets of dye liquor within successive cycles is controlled. Each cycle is initiated by the movement of the sheet-like textile structure over a distance corresponding to the pattern fineness. Within each cycle, the directing of each jet of dye liquor onto the sheet-like textile structure takes place only during a predetermined time interval which is followed by a rest time. During this rest time, which is at least as long as the recovery time of the dye-liquor jet deflection device composed of the air-supply lines (62) and of the solenoid valves (64), all the jets of dye liquor are directed away from the sheet-like textile structure. The proposed spray-printing process is also suitable for the printing of fine or complicated patterns.

Title: Electrical connector for terminating coaxial cable.
IPC: H01R24/28
Filed: 1978-10-24
Abstract: {PG,1 A rotating collar lock connector for terminating the end of a coaxial cable in which all of the metal parts therein are either stamped and formed or drawn, as opposed to being machined. Further, since no solder is required and since assembly is accomplished entirely from one direction the connector can be assembled at a single rotary type assembly machine. The connector comprises a rear metal sleeve which receives the coaxial cable at a first end thereof. A rotatable metal collar has a flanged first end which is slipped over the first sleeve from the second end thereof until it abuts against protuberances formed on the surface of the first sleeve near said first end. A metal spring means, such as a spring washer, is then slipped over the first sleeve up to said collar flange. The flanged first end of a second metal sleeve is then press fitted over the second end of the first sleeve and against the spring washer to lock the collar on the first sleeve in such a manner that the spring washer provides a spring bias between the flanges of the collar and the second sleeve. A cylindrically-shaped dielectric spacer having a concentric aperture extending therethrough is then press fitted within the first and second sleeves. A generally cylindrical male terminal is then crimped around the stripped center conductor of the cable and subsequently press fitted into the aperture in the dielectric spacer of the connector. The cable braid is secured around the first end of the first sleeve by means of a metal ring which is crimped therearound.
