In a method of driving shuttering plates a preliminary ramming plate (3), Fig. 1 (not shown) of greater wall thickness but similar cross-section to the shuttering plates is driven into the ground and immediately withdrawn from the ground and the shuttering plate (5) is inserted into the slit previously formed in the ground by the preliminary ramming plate (3). By having a combined ramming and withdrawing device for the preliminary ramming plate (3) and a small ramming device on a secondary guide parallel to the main guide (7), the shuttering plate and preliminary ramming plate can be rammed in simultaneously. In another embodiment the two can also be rammed in supported closely together. Both plates may also be fitted with a shoe to keep them together on ramming and the shoe may be left in the ground or may be withdrawn with the preliminary ramming plate. In a further embodiment the preliminary ramming plate (3) may be provided with channels for introducing a liquid sliding agent or a flushing agent.

Title: Ventilating system for underground railways
IPC: E21F1/00
Filed: 1972-09-14
Abstract: 1385072 Ventilation STADT WIEN 14 Sept 1972 [16 Sept 1971] 42721/72 Heading F4V [Also in Division E1] In an underground railway system having a plurality of stations, adjacent stations being connected by a pair of single track tubular tunnels 3, 8, Fig. 2, for travel in opposite directions, surges of air at the stations 1, 2 are prevented by connecting the two tunnels together by transverse passages 12, 14 near the stations, fans 13, 15 in the passages serving to produce a circulatory air flow through the tunnels. In the form of Fig. 3 the tunnels are ventilated by shafts 18-21 leading to the outside atmosphere, situated between the stations. Where the transverse passages open into the tunnels they are provided with baffle plates in the form of guide scoops 45, Fig. 8, of flexible material which can be adjusted from the curved to the straight position. In the curved form the air is directed along the tunnel to cause the air to circulate. In the straight position the air is projected across the tunnel and this tends to block the air surge produced by the movement of the train. The fan speed is increased to increase the blocking effect. The four ducts 18-21 leading to the outside air each have fans and one duct supplies fresh air and another exhausts used air from each tunnel. The fans are controlled in dependence upon the temperature, the oxygen content and the state of pollution of the air in the tunnels. This ventilation shaft has filters, noise silencers and means for closing the ducts altogether, creating inside a simple through passage between the tunnels. Heat exchangers may also be provided in the tunnels for heating or cooling the air sucked in.

Title: Moire gauging systems

IPC: G01B11/24
Filed: 1969-08-28
Abstract: 1276737 Gauging optically TRW Inc 28 Aug 1969 [18 Sept 1968] 42987/69 Heading G1M [Also in Division G2] Differences between the contours of a primary and a secondary object are detected by recording an interference fringe pattern formed on the primary object by two coherent monochromatic light beams, forming the corresponding pattern on the secondary object and comparing the two patterns to detect any moire pattern between them. Light from a laser 10 is split into two beams using a Twyman-Green interferometer arrangement 31, 32, 34 to form a fringe pattern on primary object 33. This is recorded as a photograph 37. The object 33 is then replaced in the same position by secondary object and the fringes recorded on photograph 37 are illuminated through a fresnel lens 38 and superimposed on the fringes formed on the secondary object. Any difference in contour produce a moire pattern. In alternative methods photographs of both objects may be taken separately and then viewed in superimposition; or both may be formed on a single plate; or the fringes on the secondary dbject may be viewed through the record of the primary object pattern. Further more than one photograph may be made of primary pattern, taken at different angles. Where the secondary object is in reality the primary object which has undergone a change, e.g. has been stressed or vibrated, the initial recording may be made by coating the primary object with a photo-sensitive layer 45. In an alternative embodiment, Fig.4, the recording of the primary object fringe pattern is made as a hologram 60 by utilizing a reference beam 62 whereat with the object beam 61. If a reconstructing beam, conjugate with reference beam 62, illuminates the hologram 60 via a mirror 67 a three dimensional image of the primary object 55 will be superimposed on the secondary object under comparison. Where the secondary object is under vibration a pulsed laser may be used.

Title: Improvements in and relating to superconductive conductors and circuits
IPC: H01L39/18
Filed: 1960-12-22
Abstract: 917,243. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 22, 1960 [March 30, 1960], No. 44026/60. Drawings to Specification. Class 37. A superconductive gate conductor is made by depositing a thin film of superconductive material on a substrate in an evacuated chamber through a pattern mask and then etching the film so that the edge portions, which contain higher impurity concentrations than the middle of the film, are disassociated from it. Subsequently the film may be annealed to render the composition of the centre portion more homogeneous but this must not be done before the etching step. The etching process is said to reduce the temperature transition width of the film and lower the critical temperature. Similarly the magnetic critical field and the magnetic transistion width are reduced. The etching may be performed by an 0.1% glycerine solution of nitric and hydrochloric acid for approximately three minutes. Various other etching methods may be employed for example using other chemical solutions, anodic etching or electro-polishing. It may be that the edge portions of the deposited film are not completely removed but remain in the form of a thin strip parallel to but isolated from the centre portion. The method may be applied to the arrangement referred to in Specification 862,178 in which a hard superconductive material is deposited on an insulating substrate followed by a layer of insulation and a soft superconductor material which is subject to the etching and annealing process described above. Specification 889,729 also is referred to.
