As described the drilling assembly 13 -includes a rotary drill bit 8 driven by motor 17 and is moved along the borehole 12 by power driving means 21 and 23 including pressure feet 22, 24. As the drilling assembly 13 progresses along borehole 12 it drags a cable 16a which, through a coupled drive means (not shown) feeds out cable 16 at the same rate. Cable 16 is attached to the signal generating means 14 which includes drive means (not shown) controlled by the tension in cable 16 so that the signal generating means moves along borehole 11 at the same rate as the drill 13  moves along borehole 12. The signal generating means 14 has an antenna 15 for radiating a radio frequency signal. This signal is detected by a loop antenna 20 which forms part of a control system which controls a drill deflection unit 9 so that the spacing d, between the boreholes 11, 12 remains constant. The control system may also utilize a second loop antenna 27.

Abstract: 1376625 Rail vehicle compressed air braking systems; valve arrangements DAVIES & METCALFE Ltd 24 Oct 1972 [26 Oct 1971] 49644/71 Heading F2F An air brake distributer 2 for railway locomotives and rolling stock is connected by a pipe 6 to a brake cylinder 8 and incorporates a twostage air exhaust choke 30 for controlling the rate at which the brake cylinder air pressure drops upon brake release via a passage 28: the choke 30 comprises a chamber 32 with outlets 34, 36 to atmosphere and a first choke stage 38 in the passage 28 and a second choke stage 40 with a smaller orifice than stage 38 and urged against a projection 28a by a spring 42. The pipe 6 is connected to a passage 4 in the distributer 2 which leads to chambers 10, 12, 14, 16 containing diaphragms 18, 20, 22, 24. Diaphragm 18 acts on a spindle 26 of a sealing valve which is opened by air pressure in cylinder 8 to connect at least one reservoir to a brake pipe when air pressure in chamber 10 falls below a predetermined level (say 1À5-2À5 p.s.i.g.). A hollow spindle 24A of a main valve communicates the chamber 14 connected to passage 28 During brake release air initially flows to atmosphere mainly via stage 38 and outlet 34 but also via passage 36, and stage 40 is held away from projection 28a by air pressure in passage 28: when this air pressure drops below a predetermined level (say 5 p.s.i.g.) stage 40 abuts projection 28a and venting is wholly via passage 36. The time taken to drop to the first mentioned predetermined pressure at which the sealing valve opens is thereby increased. The orifices in the first and second stages are preferably coaxial.

Abstract: 1452565 Pneumatic despatch systems SAUNIER DUVAL 19 Nov 1974 [19 Nov 1973 8 March 1974] 50045/74 Heading B8A A despatch-receiving station 1 of a pneumatic despatch system having a main line 2 and an end section 4 adjacent the station 1 comprises a despatch tube 5 pivotable into alignment with the end section 4 under the pneumatic control of an air-line 6 connecting the main line 2 with a chamber connected in leak-proof manner to the tube 5, a line containing a valve 7 interconnecting the air line 6 and the end section 4. In the embodiment of Fig. 1, the air line 6 opens between the ends of a double piston 12 connected to the tube 5 by a link 11 and the lower end of which contains an aperture (17, Fig. 2) so that when air is supplied by the line 6, the piston 12 rises to pivot the tube about an axis 8. When the piston 12 has risen sufficiently to align the tube 5 with the end section 4, during which movement a valve 20 carried by the tube 5 is moved to open the lower end of the section 4, air escapes round the upper end of the piston 12 to discharge a container in the tube 5 onto the section 4 and thence, via points 3, to the main line 2. During despatch, the valve 7 is closed. When a container is to be received, the main line 2 is connected to a suction source to open the valve 7 and cause the piston to move downwards slightly thus causing the tube 5 to rock to the left. This rocking causes the valve 20 to engage detent means so as to be locked in a position closing the end section 4. An arriving container is braked by a cushion of air above the valve 20 and causes the points 3 to switch to the main line 2 and allow the tube 5 to return to its rest position to unlock the valve 20 for release of the container. In the embodiment of Fig. 6 an aperture 32 on the tube 5 connects with a sleeve 33 provided with a cylinder 34 containing a valve 35. A bellows connects the sleeve 33 with a support 37 into which opens the air line 6. In this embodiment, air supplied to the bellows causes the tube to pivot into alignment with the end section 4, and then the valve 35 to open.
