Patent GB-1019379-A (GB)
Title: Improvements in and relating to crushing machines and electric sensing devices for use therewith
IPC: B02C13/31
Filed: 1963-11-05
Abstract: 1,019,379. Crushing apparatus. SOC. ANON.; DITE BABBITLESS. Nov. 5, 1963 [May 17, 1963]. No. 43643/63. Heading B2A. A crusher, e.g. a gyratory, roller, hammer or jaw crusher, includes a stress-sensing electrical device comprising a low-voltage source 12 connected to the main shaft, which is insulated from the movable crushing members, and to the frame of the crusher, and a control member in the circuit to stop the crushing action and/or switch in an alarm when a conductive object is present in the system. As described, the gyratory shaft 1 of a gyratory crusher is insulated by a plastics foot ring 2, and a plastics cross-bar bearing 3 and attrition ring 4, or alternatively the suspension ring 5 may be made of insulating material. Low voltage D.C. or A.C. is applied to the shaft 1 via a flexible lead 6, and to the frame 7, to control the servo-system 13 which controls an alarm device and/or relay circuit-breaker 14 for the motor. Tramp metal causes contact between the shaft and the framework, via the mantle, to close the circuit and actuate a sound or luminous alarm. Operation of the circuit may be delayed by a timer combined with the servo-control device 13, to permit the passage of small size metallic pieces. Deformations in mechanical members of the crusher are detected and controlled, e.g. by an extensometric gauge 15, secured to the shaft 1 at a suitably selected point, or e.g. on the arms of the cross bar 8. In a modification the control device 13 controls the opening of a hydraulic circuit, and flow back to an oil tank feeding an hydraulic lifting-jack at the upper end of the shaft, so as to permit passage of the blocking material between the mantle and crushing ring, after which the jack returns the shaft to its normal position. If however the metallic material is too large to pass, the electric circuit remains closed long enough to operate the alarm and/or stop the crushing motor. The electrical connection to the frame may be combined with the extensometric gauge, or the latter may be separate.

Title: Coupler for hydraulic lines
IPC: F16L37/23
Filed: 1963-11-06
Abstract: 996,408. Pipe coupling. PIONEER HYDRAULICS Inc. Nov. 6, 1963 [Nov. 19, 1962], No. 43894/63. Heading F2G. A readily releasable pipe coupling comprises two interfitting body members 11, 12, the bores 13, 14 of which are reduced in diameter to form valve seats 15, 17 which receive ball valves 16 18, the said bores also housing valve shields and guiding members 25, 19 carrying compression springs 28, 24 urging the ball valves on to their seats. The valve shield 25 has a closed rear end 26 and carries the spring 28 which is substantially stronger than the spring 24, preferably twice as strong. Situated within the shield is a stop member 27 allowing a total retraction of the ball valve 16 of more than twice the amount retracted in a normal open position (Fig. 3). The other shield 19 carries a slidable stop member 23 having shoulders coacting with the end wall 20 of the shield to limit the retraction of the valve. In operation the member 12 connected to an implement contains fluid under pressure, which acts on the end face of stop 23 to aid the spring 24 to keep the valve closed. On connection, the fluid pressure and spring cause valve 18 to open valve 16 beyond its usual operating position (Fig. 2, not shown). When fluid from the pressure source enters member 11, the pressure with the aid of the stronger spring 28 forces open the valve 18 to its limiting position such that both valves are equally spaced from their seats. The coupling is held closed by balls 29 held in seats in the member 12 by a retractible sleeve 30 arranged such that at all times it wholly or partially overrides the balls.

Filed: 1975-10-29
Abstract: 1522514 Facsimile systems GRUNER & JAHR AG & CO 29 Oct 1975 44536/75 Heading H4F A system for producing a printing plate, e.g. an engraved plate, from an original includes a scanner for scanning the original, the scanner being controllable so that elementary areas of the original are scanned in a chosen sequence, and includes an analog-digital converter which passes the signals from the scanner to a store associated with a data processor, the processor processing the stored data according to instructions received from an operator unit which is connected to the store and which comprises displays, means to select areas of the images displayed, and means for manual input of instructions, the processed data controlling the machine which forms the printing plate. In the embodiment described the original may be stationary and planar or may be mounted on a drum. It is viewed by reflected or transmitted light. The scanning head is moved to selected positions and at selected rates, e.g. in coordinate directions parallel to the plane of the planar original or parallel to the axis of the rotating drum. Signals from the heads are digitized and then passed to respective stores. A further input unit may provide electronically generated symbol data to a third store. The data from the stores is encoded to reduce its redundancy and the encoded data is passed to the processor store. The processor store feeds data to the operator unit. The unit includes four displays for colour separations and a display for a full colour image. It also includes a display associated with a keyboard and another associated with a coder and light pen. These devices may be used to select and address regions of the displayed image and to instruct the processor to process these regions in a desired way. The boundaries of the selected regions are displayed on a plotter. In addition the devices may be used to cause a portion of the scanned original to appear at an unrelated position on the printing plate finally produced.The operator unit may also include a drum providing a hard copy of the stored image. After the stored data has been processed it is passed to an encoder which reinserts the redundant information. The resulting signals pass to one or more engraving heads moved parallel to the axis of a drum carrying the printing plate.

Abstract: 970,860. Weighing apparatus. ZAVODY V. I. LENINA PLZEN, NARODNI PODNIK. Dec. 30,1960 [Jan. 14, 1960], No. 44740/60. Heading G1W. Movement of a weighbeam 1 from its zero position 20 to the position of equilibrium 21 is transmitted by a link 2 to one arm of a rocking lever 3 whose second arm has a toothed segment 4 and whose third arm has a weight 15. A gear-wheel 5, keyed to a shaft 19, therefore rotates through one revolution and drives a disc 7, which is rotatable on the shaft 19, through inter-meshing radial teeth 6, 9. An aperture 18 in the disc (shown displaced through 180 degrees for clarity) is thus brought opposite a lamp 13 and a photo-cell 14 operates to stop the supply of weighed material. Before the scales are emptied the disc 7 is secured against rotation by radial teeth 8 thereon being brought into engagement with a fixed projection 12 by the movement of a two-armed lever 16 due to the operation of an electromagnet 17. If there is excess weight the weighbeam rises further and the disc 7, at the next weighing operation, rotates through a less distance with the result that the supply of material is stopped sooner and the preceding error corrected. After the scale has been emptied the electromagnet 17 is de-energized by the operator and a spring 10 returns the disc 7 into engagement with the gear-wheel 5.
