Abstract: 1,204,530. Hydraulic motor control circuits. G.L. REXROTH G. m, b. H. Oct.30, 1967 [Oct. 29, 1966; March 4, 1967], No.49161/67. Heading F1P. [Also in Division H2] A servomotor 8 e.g. for operating a fluid control valve 6 is controlled by a bridge circuit comprising a valve actual position potentiometer and a desired position potentiometer 13, the motor energizing circuit including a pair of relay contacts which short circuit the armature in their rest position. Unbalance of the bridge energizes one or the other of the relays via a transistor circuit Fig.4 (not shown) and the motor is energized in the appropriate direction to rebalance the bridge at a voltage proportional to the output of the bridge (transistor amplified) plus a constant voltage, derived from a potentiometer, sufficient for starting the motor. The overall control is thus approximately logarithmic. If the speed of the motor exceeds that set by the bridge misbalance the back e.m.f. back biases the transistor amplifier and the motor is dynamically braked through a resistor (R20) permanently connected across its armature. As the bridge approaches balance the relay is released and the armature is thus short circuited to rapidly stop it. The motor is shunt wound or has a permanent magnet field. The valve 6 controls the flow of fluid to a hydraulic actuator 1 in a machine tool. Different speeds are obtained along its travel by switches 15---15<SP>111</SP> which select pre-set potentiometers 13--13<SP>11</SP> resulting in the control valve 6 taking up different positions.

Abstract: 1469525 Rotary bits SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 4 March 1974 [5 March 1973 6 Nov 1973] 49775/73 and 51432/73 Divided out of 1469524 Heading E1F A rotary bit is provided with two sets of cutting means each of which is capable of cutting a hole in a rock formation independently of the other set, one set comprising mechanical cutting elements and the other set comprising jetting nozzles. In use, during normal drilling operations the load on the bit is kept relatively low and reliance is placed on the jetting nozzles to cut the hole, the mechanical cutting elements remaining in contact with the bottom of the hole but serving simply to maintain the nozzles correctly spaced from the bottom of the hole. When it is required to drill through particularly hard rock, the load on the bit is increased to cause the mechanical cutting elements to effect a drilling action, the supply of drilling fluid to the nozzles optionally then being decreased to a level catering simply for cooling of the bit and removal of the cuttings. In the diamond bit shown in Figs. 1 and 2, diamonds 8 are arranged on spiral lands 9 in areas 10-13 separated by water channels 14-17 into which the nozzles open, the centre of the hole being cut by larger diamonds 18 or additional nozzles 22. Diamonds 20 in the side of the bit can cut only in a downward direction. In an alternative embodiment of diamond bit, the water channels have a spiral form and the diamonds in each area are arranged on spiral or circular lands or are set into the face of the bit. Each diamond field may include secondary water channels, and junk slots may be provided in communication with the primary water channels. The primary channels may be closed at their radially inner and outer ends alternately. In the embodiment of Figs. 5 and 6, the bit has two roller cone cutters and three sets of nozzles 58, 59, 60. The nozzle spacing may be as disclosed in Specification 1469524 to prevent erosion of the side wall of the borehole during jet drilling the distance between the side wall and the nearest nozzle should be at least 3.5 times the nozzle diameter.

Abstract: 1536127 Control of electro-erosion FUR INDUSTRIELLE ELEKTRONIK AGIE LOSONE BEI LOCARNO AG 4 Dec 1975 [20 Feb 1975]  49902/75 Heading G3N An electro-erosion process is automatically controlled by adjustment of such process conditions as flow of flushing medium and mark/space ratio of working discharge pulses in dependence on signals 101, 201 respectively representing the rate of wear of the tool electrode 1 and of the workpiece electrode 2. A detector 6 of conditions in the working gap 3 establishes, with respect to a desired value input 15, an error input 42 to a unit 100 which computes squared integrated error as described in Specification 1454088. The rate-oftool-wear output 101 is derived from this computation. Unit 200 compares the number of actual discharges across gap 3 with the total number of applied pulses (some of which do not produce discharges) and this comparison provides the rateof-workpiece-wear signal 201. The relative effects of the signals 101, 201 may be time variable, e.g. the workpiece erosion rate may be relatively high initially and lower during a later fine finishing stage.
