Filed: 1927-07-07
Abstract: 274,095. I. G. Farbenindustrie Akt.- Ges. July 8, 1926, [Convention date]. Addition to 273,321. Samples furnished. Cyclic ketones.-The process of the parent Specification, according to which cyclic ketones are produced by condensing hydrocarbons or their derivatives having a pair of free positions in peri-position to one another with maleic anhydride, is modified by replacing the maleic anhydride by dicarboxylic anhydrides derived from it by addition at the double bond of hydrogen or another additive molecule such as chlorine, bromine, hydrochloric acid, or hydrobromic acid. As intermediate products there may be produced open chain ketonecarboxylic acids. According to examples (1) accnaphthene is condensed with succinic anhydride in presence of sodiumaluminium chloride to yield a cyclic ketonecarboxylic acid; (2) the same condensation is effected in two stages, the first in presence of aluminium chloride and nitrobenzene at ordinary temperatures whereby an open chain ketonecarboxylic acid is produced, and the second in presence of sodium-aluminium chloride at high temperature. The acenaphthene may be replaced by naphthalene, 1-methyl or 1-chlor-naphthalene, or anthracene.

Title: Line drawing photoexposure device with image rotating means
IPC: G03B15/00
Filed: 1973-04-16
Abstract: 1385165 Photo-plotting apparatus; optical projection GERBER SCIENTIFIC INSTRUMENT CO 16 April 1973 [24 July 1972] 18240/73 Headings G2A and G2J A photo-exposure mechanism for exposing lines by moving a light spot over a photo-sensitive surface comprises a support surface 14 for the photo-sensitive material 16 and a photo-exposure device 20 mounted for movement in a plane parallel to the surface 14 and comprising means 34-48 which illuminate an aperture e.g. in wheel 50, and an optical imaging system 54-58 which forms an image of the aperture on the photosensitive surface, this image constituting the light spot 53, the path of the light rays through the system having at least one zone of non-parallel rays in which a non-restricted image rotator 58 (defined below) is located for rotating the image relative to, and in the plane of, the sensitive surface 16. A non-restricted image rotator is one which will rotate an image without causing dispersion of the image rays even if the incoming rays are not parallel. The rotator shown in Figs. 5 and 6 comprises a mirror assembly having three reflecting surfaces 84, 86, 88 mounted on first and second support members 94, 96. These members are mounted in a barrel member 62 which rotates in a frame 68 about a centre line 64. The support members 94, 96 and thus the reflecting surfaces are adjusted by screws 98, 104 to bring the optical axis of the departing rays a and f colinear with the centre line 64. As shown in Fig. 6 on passing through the assembly rays a and b are rotated through 180 degrees. If the barrel member 62 is rotated through 90 degrees counter-clockwise, Fig. 5, the common plane of a and b becomes parallel to the surface 86 and no rotation about line 64 occurs. Thus to maintain a given axis of the projected light spot perpendicular to the path of travel of the spot the mirror assembly is rotated through one half the angular change of direction of the line of travel of the spot. In alternative embodiments the mirror assembly is replaced by a rotatable prism, e.g. a Peehan or reversion prism, in which the entrance and exit faces of the prism are perpendicular to the optical axis of the entering and departing rays and which has an odd number of reflecting surfaces.

Title: Improvements in and relating to distance indicating devices with reduction gearing
Inventor: GRIFFITHS LEONARD
IPC: G01P3/46
Filed: 1949-07-13
Abstract: 698,869. Odometers; counting-apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. July 11, 1950 [July 13, 1949], No. 18504/49. Classes 106 (i) and 106 (iii). A distance-indicating device for attachment to locomotives and rail cars, comprises reduction gearing driving a contact tmaker operating an electro-magnetic counter, the gear reduction necessary to actuate the counter being effected in two stages, first through a double spur gear, and secondly by an eccentric causing a member to turn a notched wheel. As shown, a gearwheel 12 is coupled to and rotates with the axle of a pair of track wheels. Through the agency of gears 12, 14, 15 and 16 a reduction of the order of 10: 1 is effected for an eccentric 19 which, on each rotation in either direction, causes a notched wheel 25 to be moved in a clockwise direction by one notch through the medium of an arm 23. The reduction ratio may finally be from 400 or 700 to 1. As the wheel 25 rotates, a pin 36 secured to the wheel 25 carries with it a weighted member 35 freely pivoted on the axis of the wheel 25. When the weight 35 reaches top dead centre it then falls by gravity about its bearing striking on the way a lever 37 to cause two contacts 47 and 42 to touch momentarily and thus operate an electromagnetic counter circuit registering the mileage covered. On the axle of the gear-wheel 12 there may be mounted a rotor rotatable within a fixed stator, electrical connections to the stator being used to enable the speed at which the locomotive or rail car is moving to be determined. The whole device may be resiliently mounted on an axle box cover of the locomotive or rail car. Specification 669,480, [Group XXXV], is referred to in the Provisional Specification.

Title: A device for binding railroad sleepers or the like
IPC: E01B3/08
Filed: 1945-07-20
Abstract: 621,029. Band - strainers. SOC. NATIONALE DES CHEMINS DE FER FRANCAIS, and DELOR, G. C. July 20, 1945, No. 18651. Convention date, July 4, 1942. [Class 45] In a device for banding sleepers and like objects of the kind in which the free end of the band, after having been passed through a ring, is gripped and tensioned by a screw-actuated strainer, and in which the strainer is in the form of a lever adapted to be turned about trunnions on a support bearing on the sleeper so as to bend the tensioned band over the ring and on to itself, means are provided on the support so to position the ring in relation to the trunnions that the tension in the band remains substantially constant during the bending operation. In practice, one end la of a band 1 is threaded through a rectangular ring 2 and bent by hammering over one side of the ring and on to itself as shown in Fig. 6. The ring is applied to the sleeper with the end 1a of the band turned inwardly, and the band is then bent around the sleeper and its free end 1b passed upwardly through the ring and through a support 4, Fig. 2, and the hollow screw 8a of the strainer. The strainer tapers towards its lower end where it is provided with a pair of bearing surfaces by which it is pivoted on trunnion 5 extending laterally from the support 4, which latter rests on the sleeper and is recessed on its under side to fit over the ring 2. On the rotation of a nut 9 by handles 10, jaws 16 are caused to grip the free end of the band and draw it upwardly. When the band is sufficiently tensioned, the strainer is rocked clockwise about the trunnions 5 to bend the band over the ring, the ring being so positioned by the recess relatively to the trunnions that the tension in the band remains constant during the bending. The strainer and support are removed and the end of the band hammered down on to itself where it is permanently held by a collar 3, Fig. 6, formed from the waste end of the band.
