Title: Improvements in apparatus for under water rock breaking
Inventor: SMIT ABRAHAM CORNELIS DE
IPC: B21J7/44
Filed: 1958-05-03
Abstract: 852,095. Rock-breaking apparatus. WESTMINSTER DREDGING CO. Ltd. July 30, 1959 [May 3, 1958], No. 14192/58. Class 68(1). In an underwater rock-breaking apparatus having a rock needle or drop hammer 1 which is hoisted by a winch drum 4 and cable 2, and is dropped by de-clutching the drum 4 from the shaft 5, the clutch is operated by a servomotor responsive to slackness in the cable, so that, after impact, the slackness in the cable operates the servomotor to clutch the drum to the shaft and to hoist the hammer. The servomotor is operated to de-clutch the drum 4 by a control device 12 which is actuated by a stop 17 on the cable 2 at the top of the ascent of the hammer, the device being separately suspended from a sheave 14 by a cable 13 on a hand-winch 15. As described, the servomotor system is pneumatic. The cable 2 is trained over a sheave 3 at the head of a jib (not shown) and the hammer 1 is guided in a sleeve (not shown) suspended from the jib. Pressure air is supplied at 20 and with the valves 21, 24, 26 open and the valves 22, 27 closed, the pneumatic servomotor clutch may be operated manually by the valve 23. With the valves 24, 26 closed and valves 21, 22, 27 open air is supplied by the line 9 to a piston valve 8 which is closed when the cable 2 is taut, but when, on impact, slackness occurs, the air pressure moves the piston rod 6 inwardly and air is supplied to the line 10 leading to a piston valve 11. The piston of the valve 11 is moved by the admitted air pressure to open ports whereby the line 20 is connected through the 'valve 27 and line 28 to the servomotor to clutch the drum 4 to the shaft 5 to hoist the hammer. When the stop 17 hits the bracket 16, the valve 12 is actuated to connect the line 19 with the line 18 and pressure is applied to the opposite end of the piston of the valve 11. The piston is moved back to its original position, the pressure spaces in the valve are connected to a venting port, and the servo-motor operates to de-clutch the drum from the shaft.

Title: Improvements in or relating to Telecommunication Line Fault Location Systems
IPC: H04B17/40
Filed: 1967-03-29
Abstract: 1,155,653. Automatic control of current and voltage. SIEMENS A.G. March 29, 1967 [March 31, 1966], No. 14194/67. Heading G3R. [Also in Division H4] In a repeatered line where the repeaters are normally supplied via the line from a constant current source, the supply voltage is monitored and if, due to a break in the line and the ingress of moisture causing the supply circuit load impedance to increase, the voltage rises above a predetermined value the source is changed to constant voltage control to prevent an excess voltage, sufficient to cause breakdown of the line insulation or the overload protectors in the repeaters, being applied to the line. The arrangement permits continued operation of the repeaters up to the line fault, possibly at reduced effectiveness, and therefore the use of conventional fault location methods using the high frequency transmission channels. The figure shows a system in which D.C. power is supplied to a line U2 from a source S which is regulated in a switching control system including a regulating circuit R and a pulse generator T with the current being monitored by a resistor Si which via the comparator bridge circuit T3 and T4 controls the impedance of a transistor T2 connected across the control terminals K1 and K2 of the regulating circuit to maintain the current supplied to the line constant. In addition the voltage supplied to the line is monitored by the circuit comprising Zener diodes Z limiting resistor R L  and variable resitor Su, the voltage across the resistor Su being used to control the impedance of transistor T1 so that under normal operating conditions T1 is non- conductive but if the voltage across the line rises above a predetermined value T1 is made conducting to prevent further increase in the voltage applied to the line. The current control circuit is still operative so that should a short circuit develop at the line break the current will be limited to its normal value. The two monitoring circuits may control a single variable impedance between the control terminals of the regulating unit.

Abstract: 848,568. Capacitance variation detection. LANCASHIRE DYNAMO ELECTRONIC PRODUCTS Ltd. April 30, 1958 [May 6, 1957], No. 14349/57. Class 37 Apparatus detecting small variations of capacitance e.g. for controlling the admission and/or discharge of liquid or solids to or from a container in response to capacitance changes of a probe due to the presence or absence of material, comprises (Fig. 4) an oscillator wherein the emitter of a transistor P is connected to tap T of a tuned circuit LC interconnected with the transistor in feedback circuit, including a virtual tapping of the inductance of the tuned circuit determined by the ratio of capacitances KC,C in series there-across. Potentiometer R  1  R 2  across the supply determines the bias and collector voltages and the probe is attached to the junction C to LC so that if the capacitance ratio exceeds that of the turns of the inductance on each side of tap T, the oscillator amplitude varies proportionally to the probe capacitance, and is inductively coupled over coil L 1  to a rectifier feeding transistor amplifier P operating relay R 2 , which may control an inlet valve which closes to prevent admission of further material to a vessel when the level therein exceeds a predetermined value, or may control an outlet valve which closes to prevent loss of material when the level falls below a predetermined value. Alternatively, the current may be adjusted to be oscillatory or non-oscillatory as the probe capacitance is in defect or excess of a control value.
