Title: Tunneling method and apparatus
IPC: E21D9/00
Filed: 1974-03-22
Abstract: 1457178 Tunnelling GEWERKSCHAFT EISENHUTTE WESTFALIA 22 March 1974 [27 March 1974] 12779/74 Heading E1F A tunnelling technique involves driving two spaced parallel pilot tunnels 2, 2' and interconnecting these by a transverse tunnel following the contour of the roof of the main tunnel which is to be driven along the path between the two pilot tunnels, the transverse tunnel serving to receive a top-heading tunnelling machine comprising an advanceable sectional frame whose sections, e.g. the sections 6-8 of Fig. 2 are pivotally interconnected end-to-end as at 20 and are pivoted relative to each other by rams 21 carrying male fittings 25 received in complementary female fittings 26, the rams optionally being actuated in response to means measuring the loads on the frame. The frame carries groups of tunnelling shield boards 13 of which each group is advanceable while another is held stationary. The frame also includes skids 14 on which is mounted a conveyor 12 supporting a cutter 11 movable along the conveyer to cut away material beneath the boards 13, the debris being conveyed to tunnel 2' for removal. As the frame advances, a roof lining is cast or assembled in the space therebehind, and once the roof lining is able to support a load a high-speed wide-face tunnelling machine is used to excavate the material below the lining to form the main tunnel. In one suggested operating mode, the pilot tunnels are driven a predetermined distance and their leading ends are then interconnected by a transverse tunnel in which the profiled top-heading tunnelling machine described above is installed and moved in reverse direction to form the roof space of the main tunnel between the previously-driven sections of the pilot tunnels, this cycle then being repeated as necessary. In another suggested operating mode, the top heading tunnelling machine advances simultaneously with and in the same direction as the machines driving the pilot tunnels, the latter in either case finally being filled with concrete or lining except in areas defining access passages. The cutter 11 may be a planar with cutting bits or rotary cutting tools, and may be hauled along the conveyor 12 by an endless traction element. In another embodiment, the cutter is replaced by a rotary cutter chain. The material removed by the cutter -11 may alternatively be transfered to the pilot tunnels under gravity or it may be displaced towards the pilot tunnels by the cutter itself. The shield boards 13 and the skids 14 may have retractable anchoring sprags.

Title: Improvements in the production of adhesive bonds between rubber or rubber-like polymers or copolymers and rigid polymers or copolymers
Inventor: WAKE WILLIAM CHARLES
IPC: C08J5/12
Filed: 1953-05-11
Abstract: A rubber or rubber-like polymer or copolymer is bonded to a rigid polymer or copolymer, e.g. polymethylmethacrylate, by a method which includes applying to a surface of the rubber or rubber-like polymer or copolymer a tertiary butyl compound capable of generating free radicals which can react with both materials to be bonded and cause them to unite.  The tertiary butyl compound may comprise tertiary butyl perbenzoate, di-tertiary butyl peroxide, tertiary butyl hydroperoxide, 2,2-bis (tertiary-butyl peroxy) butane, or mixtures thereof.  In addition a monomer which forms the or part of the basis of at least one of the polymers or copolymers may be applied to the surface to be bonded of the rubber or rubber-like polymer or copolymer.  In one example unvulcanized natural rubber is immersed for about 1/2 hour in a mixture of 10 parts by weight of tert. butyl hydroperoxide and 2 parts ditert. butyl peroxide.  The rubber is then dipped into monomeric methyl methacrylate and moulded between polymethylmethacrylate sheets under a pressure of 3000 lb. per sq. inch for 2 1/2 hours at 90 DEG  C.  The method is also stated to be applicable to the bonding of rubber to polyethylene, an isobutene-vinyl carbazole copolymer, a mixture of polyethylene and polyisobutene, and polyesters cross-linked with styrene.  The method may be used in the production of laminated sheets for use as cockpit covers for aircraft.

Abstract: 947,589. Conveyer systems. BAIRD & TATLOCK (LONDON) Ltd. March 30, 1961 [April 12, 1960], No. 13088/60. Heading B7L. In an endless carrier system of the type in which articles are carried along a track by means of an endless carrier having means for driving it so that it travels along or adjacent to the track, the carrier automatically engaging an article at the beginning of the track and automatically disengaging it at the end of the track and means for stopping and restarting the carrier when the article reaches a predetermined position in the track, catch means are provided for coupling the articles together in advance of the track and a catch-operating member is provided associated with the track so that when the first article is engaged by the carrier, the second article is moved into position to be engaged by the carrier, the catch means of the second article is operated to disengage the first article and a second catch operating means is provided so that prior to disengagement of the first article with the carrier, its catch means is operated so as to recouple it with the preceding article and to move the latter away from the track. The invention may be applied repetitive chemical treatment in which a succession of holders 16-20, Fig. 1, for beakers are moved along a horizontal plate 4 by means of a continuously driven chain 5 and tending between sprockets 2, 3 and driven by a sprocket 9 from an electric motor (not shown) incorporating an electric brake so that it may be stopped and started at intervals. The holders 16-20 are moved by lateral pegs 11, 12, 13 spaced at equal intervals along the chain. The beaker holders are coupled together and pushed manually along the input track 14. When a beaker holder (e.g. 17) reaches the position shown, it is pushed up by the next peg 11 on the chain 5 and simultaneously a cam 44 depresses a lever 39, Fig. 3, on the beaker holder 16, thereby bringing a hole 42 on a vertically moving bar 35 into register with a hole 34 in the wall of the holder so that the head 39 of a coupling pin 31 on the preceding holder is released. At the end of the track the holder 19 becomes disengaged from the driving peg. The next succeeding holder 18 is moved into contact with this and accordingly slides the holder 19 forward, the lever 39 being allowed to rise by a second cam 45 so that the holders are recoupled. During one of the dwell periods of the chain 5, the holder (e.g. 18) in the appropriate position may be moved upwards by a table 47 as in Specification 947,590, for a chemical treatment, being returned to position before the chain restarts. A solenoid-operated gate 52 which is open only when the motor driving the chain is operating, may be provided between the input track 14 and the track 4. Specification 853,469 also is referred to.

A missile 20 having a rear jet propulsion unit 21, 22 to provide or assist in initial acceleration of the missile has a further unit 23, forward of the centre of gravity G of the missile, for cruising and control. The unit 23 comprises four nozzles 24, 25 and 28 (29) equi-angularly disposed about the axis X-X of the missile. Each nozzle is divergent and of elliptical cross-section as shown in Figs. 5 and 6 and each wall portion 46, 47 is formed with an aperture at 34, 35 which are connected by a duct 36. Means are provided, e.g. a source of compressed gas connected through a valve to one or other end of duct 36, to initially deflect the propulsion jet from a central position to position j 1  or j 2  so that it sticks to wall portion 46 or 47. Thereafter fluctuation of pressures automatically created successively at apertures 34, 35 and transmitted through duct 36 will cause the jet to oscillate continuously from one side to the other of the nozzle. Means comprising e.g. a control jet discharged selectively through a wall portion 46 or 47 will cause the jet to stick to one wall or the other for a longer or shorter time than provided by the successive fluctuations thereby providing a lateral aysmmetric force to control the direction of the missile. The oscillation and control of the propulsion jet may be effected by oscillating vanes in the nozzle wall instead of by gas jets. Different arrangements of nozzles all embodying the above-described features are disclosed.
