Title: Improvements in or relating to range finders
IPC: G01C3/12
Filed: 1945-12-20
Abstract: 605,490. Range-finders. KODAK, Ltd. Dec. 20, 1945, No. 34573. Convention date, June 23, 1943. [Class 97 (i)] A coincidence or stereoscopic range-finder has an adjustment mark in each of the comparison planes in'which the object images are formed and images of each mark are projected in opposite directions through the whole optical system of the finder into the other comparison plane, coincidence or stereoscopic coincidence of the images indicating that the instrument is correctly adjusted. The stereoscopic finder shown in Fig. 1 comprises prisms 11 and objectives 12 forming images in comparison planes 13 which are observed by eyepieces 16 and brought into stereoscopic coincidence with marks in those planes by a light deviator 20. The left-hand mark 23 is illuminated by lamp 22, the light from which is collimated by lefthand objective 12 and is directed into the righthand system by prisms 11, 25, 25 and 11 to form an image in the right comparison plane 13. Similarly, an image of the right-hand mark is formed in the left comparison plane. Coincidence in depth of the marks and of the images thereof as seen in the eyepieces indicates correct adjustment, a light deviator 21 being provided to correct any error. Fig. 2 shows a coincidence finder in which the object images formed by prisms 31 and objectives 32 are justaposed in the plane 38 of eyepieces 36 by crossed prisms 33, 34. The adjustment mark is a line in the plane 38 illuminated by lamp 37, light from one half of the line passing righthanded via auxiliary prism 39 into the left optical system and light from the other half passing in the reverse direction to form two images in the plane 38, coincidence again indicating correct adjustment. The prism 39 may be omitted and prism 31 replaced by mirror, each having a bevel surface to reflect the mark image beam into the other system. The Specification as open to inspection under Sect. 91 describes a modification of the finder shown in Fig. 2 in which the marks are replaced by a scale and index, the images of which indicate range directly. This subject-matter does not appear in the Specification as accepted.

Filed: 1961-09-28
Abstract: 993,062. Relaying railway tracks. F. PLASSER, [trading as FRANZ PLASSER BAHNBAUMASCHINEN]. Sept. 28, 1961 [Oct. 27, 1960], No. 34915/61. Heading E1G. A method of renewing permanent way tracks in which old track sections 4 are taken up individually, inverted and then conveyed away in the longitudinal direction of the track, and in which the new track sections 5 are fed also in inverted position to the laying site longitudinally of the track, whereafter they are reinverted and lowered into position. In Fig. 1, new track sections are stacked in wagons 1, rearwardly of a track laying machine 2, in the direction in which old track sections are being replaced one after the other, the old track sections, after replacement, being stacked in further wagons 3 forwardly of the machine 2. Grippers 6 on the machine 2 grip the rails and raise the section 4, and the body of the machine 2 2 is rotated through 180 degrees with the section 4, which is then conveyed to and lowered into a wagon 3. Meanwhile, the section 5 is lifted out of a wagon 1 and conveyed to the machine 2 to take the place of the section 4. The body of the machine 2 is then again rotated and the grippers 6 actuated to lower the section 5 into position. Fig. 3 shows one end of the machine 2. The track sections are moved along guideways 8 and the grippers 6 are retractable into the body of the machine during its rotation. A device 7, e.g. a ballast rake, plough or levelling plate, which is also retractable may be used to treat the ballast whilst the rail sections are being transferred from and on to the body of the machine 2. It is also possible to provide ballast packing or cleaning devices. For laying curved track sections the grippers 6 are able to be moved longitudinally and transversely of the body of the machine 2 and to be locked in position so that a new track section can forcibly be given the correct curvature before laying. The wagons 1, 3 each have guideways 8 fixed to arms 8<SP>1</SP>, Fig. 9, pivoted at the bottom of the wagon. Frames 11, which pass between the rails and between two adjacent sleepers have retractable lifting grippers 12, which engage with the rails of a track section and lift it out of the wagon to a position where the guideways 8 can be pivoted back underneath the rails. Preferably the movements of the grippers 12 and guideways 8 are coupled so that the guideways 8 move out as the grippers 12 come into operation. Further guide frames (not shown) may be provided, without the lifting grippers 12 to locate the track sections in the wagon and rollers, preferably motor driven, may be provided opposite these frames to facilitate the movement of the track sections along the guideways 8. The machine may be rendered automatic in operation.

Filed: 1936-12-22
Abstract: 487,603. Ornamental crepe paper. DENNISON-VICTOR CO., Ltd. Dec. 22, 1936, No. 35172. Convention date, July 8. [Class 96] [Also in Group XV] An ornamental crÛpe paper is prepared by treating the paper prior to the crepeing operating with a crepeing solution containing glistening flakes such as mica so that the flakes are anchored to the surface in the subsequent crÛping operation. In one form of apparatus for carrying out the process, the paper passes from a roll 1 between two rollers 2, 5, the lower roller 5 dipping into a bath 4 of crÛpeing solution. A pump P may supply the solution to nozzles 14, 15, whereby it can be applied to one or both sides of the paper. The flakes are mixed with the solution in the bath 4 and applied to the paper with the solution. After the crÛpeing operation, the paper may be printed with a pattern by rollers 6, 7. From the rollers the paper passes to a drying drum 9 and may subsequently be corrugated transversely by rollers 10, 11. In addition, the paper may be calendered by rollers 12, 13 so as to flatten the ridges and produce a sheen. Finally, the winding roll 16 may be driven at a faster rate than the rollers 12, 13, so as to stretch the paper and further vary its appearance. The flakes may be before they are mixed with the solution. A paper such as tissue paper formed wholly or partly of alphacellulose and having an open formation may be employed, the flakes tending to become enmeshed in the fibres.
