Abstract: 1469022 Boring earth &c J BASE 31 Oct 1975 [6 Sept 1974] 39104/74 Heading E1F [Also in Division H2] A cable seal unit for an earth-boring drill string consists of a tubular member 1 having threaded ends 2, 3 so that it can be incorporated in the drill string, the wall of the member 1 being formed with an aperture 4 through which a cable may pass from the interior to the exterior of the string, and sealing means for sealing the aperture around the cable (not shown). As described the unit is incorporated in a non-rooting drill string having a down-the-hole mud driven motor, the cable being used to monitor and/or control the direction of drilling. The aperture 4 is formed with a shoulder 5 and is sealed by resilient packing rings 7, e.g. of rubber or neoprene, which are compressed against the shoulder 5 or an annular packing seat 6 by an annular nut (not shown) screwed into a threaded portion 8 of the aperture. The cable may also be secured by a two-part cable clamp (not shown) which matches the outside contours of the unit 1 and which is secured by screws engaging threaded holes 13. The unit 1 is also provided with an enlarged diameter portion 14 so that the cable is protected should the unit come into contact with the side of the borehole.

Title: Improvements in and relating to the control of machine tools
Inventor: RUSSIG ARMIN

Filed: 1968-08-19
Abstract: 1,242,751. Automatic machine tool control. WERKZEUGMASCHINENKOMBINAT FRITZHECKERT. KARL-MARX-STADT. Aug. 19, 1968, No.39531/68. Headings G3N and G3R. In a control system for a cutting machine tool two or more variables N and P which determine operating conditions for the cutting process, are measured and fed to respective threshold switches 4, 5 and 6, 7, 4 and 7 determining the upper limits N max  and P max  of the variables and 5 and 6 determining the lower limits 0À95 N max  and 0À95 P max  of the variables. Should either of the maximum values be exceeded signals are passed from 4 or 5 through switching matrix 8 to an OR 9, the output of which reduces the feed speed through a setting member 11 and also increases the spindle speed through a setting member 13. If both of the variables N and P fall below the desired minima, the output of AND 10 increases the feed speed and reduces the spindle speed through setting members 11 and 13. The ratio between the alteration of the feed speed and spindle speed is pre-selected so that the cutting time remains constant. The feed speed is limited to a maximum value S max . The machine tool is programmed and when started a sequence generator in the matrix interrogates the inputs 4, 5, 6 and 7. Any output from the OR 9 drives a counter in a reverse direction one step, so that if the counter started from zero a relay in its zero output stage is deenergized and a relay in its -1 stage is energized. Energization of the -1 stage relay switches in the corresponding resistance of a parallel resistance network in series with a feed speed control motor and a similar resistance chain controlling the speed of the spindle drive. The spindle drive motor control comprises a plurality of parallel resistance chains, each chain comprising for example three resistors in series, and the ratio between feed speed and spindle speed can be pre-selected by switching any one of the resistors in the chain out of circuit. Output from the AND 10 drives the counter in the forward direction. Instead of resistance networks, the co-ordination of feed speed and spindle speed may be effected by means of respective stores for the feed speed and spindle speed, each storage position of the feed speed store being allocated to a predetermined storage position of the spindle speed store. The store contents are pre-selectable by an external programme.

Abstract: 1,124,295. Route setting matrix. G.E.C. ROAD SIGNALS Ltd. 30 Dec., 1965 [30 Sept., 1964], No. 39811/64. Heading B7N. A route-setting system incorporates a matrix formed by a plurality of groups of vertical conductors and a plurality of groups-of horizontal conductors, each vertical group being connected to a module which defines a route through the track network, each horizontal group being connected to a unit associated with an entry point with associated signal, an exit point or a set of points in the network and a series of interconnecting modules connecting selected vertical and horizontal conductors. Assume a route between signal S3 and exit point X1 operation of the entrance-exit pushbuttons B3, B4 applies potential to one of the conductors in the horizontal group associated with entry signal S3 and one of the conductors in a similar group associated with exit point X1. Via an entrance interconnecting module and a similar exit module these signals select the unit, associated with a vertical group, defining the required route. This route unit then applies a " select " signal via a conductor in its vertical group to a counter move interconnecting module which routes the signal horizontally to the unit associated with signal S2 as a request to counter any move by that signal, a confining " have countered " signal is then returned to the counter move module. The select signal is also applied to intersection modules associated with the normal setting of points P1B and the reverse setting of crossover P2 from which signals are directed horizontally to the respective points units to select the required position of the points. Return " have selected " signals from these units are then directed vertically and in conjunction with the " have countered " signal provide a signal which is applied via the route unit and the entrance module to the entry signal unit as a lock entrance signal. The confirming " have locked " signal is then supplied to the entrance module and thence vertically to the route unit in which it operates a relay indicating the availability of signals and points for the route. Operation of the relay initiates a drive pulse which via a similar route is supplied to all signal and points sets to set and lock the selected condition. A further circuit is then set up to check the route before operation of the entrance signal. The matrix is mounted on a network of vertical and horizontal channel members, trays being mounted on one side of the network to accommodate the units associated with the signals and points and the spaces between the channel members accommodating the modules on slide-in trays.

A writing lead comprising graphite particles bound together by carbon to carbon bonds, being substantially free of ceramic substances and containing combined hydrogen up to a maximum of 10% by weight is produced by mixing graphite powder with a binding agent comprising a heat hardenable phenol-formaldehyde or a furane condensation product or a hydrocarbon compound, e.g. coal tar or a pitch mixture, forming the mixture into a rod and subjecting the rod to heat treatment at a temperature above 400‹ C., the treatment being selected in accordance with the degree of hardness required in the manufactured lead and being effected in a non-oxidizing atmosphere so that combined hydrogen up to a maximum of 10% by weight is present in the lead. The degree of hardness of the lead may be regulated by the temperature of the heat treatment, the chemical composition of the binding agent and the proportion of micro-crystalline natural graphite in the graphite powder used. The graphite powder may contain various graphites, preferably at least 30% by weight being the microcrystalline natural graphite (density less than 2À24 g./c.c.), and may consist partly of mixed graphite (density 1À7-2À26 g./c.c.). Up to 80% by weight of the graphite may be electrographite. The completed lead may be impregnated with a resin which is subsequently, hardened, or is subjected to a heat treatment at over 400‹ C. in a non-oxidizing atmosphere.
