Patent GB-2096675-A (GB)
Title: Method of removing an inner conduit which is grouted in an outer conduit
IPC: E02B17/00
Filed: 1982-03-26
Abstract: A method of removing a conduit 6 cemented within a larger, surrounding conduit 4, for example a pile grouted within a sleeve of an offshore platform, comprises circumferentially cutting the pile from within at longitudinally spaced locations, the circumferential cuts being substantially connected by at least one longitudinal cut therebetween. Both circumferential and longitudinal cuts are preferably made with explosives, specifically linear shaped charges 26. Subsequent to the cutting operations, the pile is mechanically removed in sections from the sleeve, if desired, the grout within the sleeve may be fractured explosively, and removed from the sleeve, or permitted to fall into a "rat hole" created at the bottom of the pile below the lowermost circumferential cut. <IMAGE>

Patent GB-2128824-A (GB)
Title: Clock pulse generation circuit
Inventor: SARSON GARY ALFRED
IPC: H03L7/06
Filed: 1982-10-06
Abstract: A clock pulse generation circuit e.g. for use in a digital telephone exchange is capable of operating as a free-running system when connected to the network over analogue trunks, or in synchronism with the network clock when connected to the network via digital trunks. The circuit is based on a phase-locked loop including a crystal (X) controlled voltage-controlled oscillator (VCO) whose output forms one input of a phase comparator (PC). The latter has a second input (RC) on which a remote clock is received when the exchange is connected via digital trunks. The phase comparator, in the absence of a clock pulse train on the second input (RC), emits a condition which causes the oscillator (VCO) to run at its mid-frequency. However, if a remote clock is received on the phase comparator's second input (RC), the comparator (PC) produces a condition dependent on the relation between the remote clock and the oscillator output. This forces the oscillator into synchronism with the remote clock. The change between the operating condition occurs automatically. <IMAGE>

Title: Method of control of NC machine tools
Inventor: MORITA EIICHI
IPC: G05B19/41
Filed: 1982-11-09
Abstract: In a NC machine tool all control data necessary for preparing machining data is inputted into a control device by key switches provided on an operating board. The data necessary for machining a workpiece stored in a microcomputer contained in the NC machine is reduced to the lowest minimum, while various data, such as the paths of movement of tools during rough machining, rough finish machining and finish machining, actually needed for machining the workpiece are successively computed on the basis of the data stored in said microcomputer in advance. Thus, data associated with a variety of workpieces can be processed with a minimum of memory capacity, and complicated shapes having concaves and convexes can accurately be machined in a simple operation. A variety of different tools, identified by respective code numbers, can be used and an optimum tool path prepared. <IMAGE>

Title: Track curve lining method and apparatus
Inventor: BRADSHAW BRUCE WILLIAM
IPC: E01B35/04
Filed: 1983-09-20
Abstract: A railroad track curve is plotted by measuring ordinates (58) at a fixed point (61) of a fixed length reference line that is moved to a series of incremental points spaced around the curve (59), and the ordinates (58) are stored in a data processor memory. The data processor calculates theoretical ordinates for an ideal curve which most closely fits the measured ordinates (58), and the track is shifted at the incremental points under control of the processor a distance and direction corresponding to the deviation between the measured and calculated ordinates. The system permits determination of transition points for simple and compound curves, and allows superelevation values to be selected and intermediate values calculated for smooth transition between tangent and constant curve track. The reference line may be established by a light beam (14), and the processor may be part of a self-propelled, on-track lining machine. <IMAGE>
