Title: Track lubricator
IPC: B61K3/00
Filed: 1961-07-06
Abstract: 939,087. Lubricators &c. POOR & CO. July 6, 1961 [Nov. 25, 1960], No. 24455/61. Class 12 (3). [Also in Group XXVIII] In a railway track lubricator of the type referred to in Specification 854,490, a connecting linkage between the lubricant pump and distributer comprises a ramp lever 1 with integral stub-shaft 2 located in a journal housing 3 of a support-plate 4. The end of stub shaft 2 has a splined portion 6 for entering a corresponding splined bore 9 in a socket member 7. The member has a radial pin 8 which together with a pin 5 on the housing 3, serves as an anchor for a spring 5 which returns the ramp lever to its operating position and in co-operation with the return spring in the pump mechanism eliminates backlash. An identical socket member 7a is in splined connection with pump shaft 15 and in connection with socket 7 by a coupling bar 12, the ends of which have tapered flat portions with elongated heads 11 which engage elongated recesses in the ends of socket members 7 and 7a. Axial movement of the shaft 15 to facilitate assembly of the parts is permitted by the release of a collar within the lubricant pump housing whereby the shaft 15 may be withdrawn away from the distributer.

Abstract: 318,105. Universelle Cigarettenmaschinen-Fabrik J. C. Muller & Co. Aug. 27, 1928, [Convention date]. Cigarette-making machines. - In a tobacco spreader in which the fibres are taken up from a conveyer band 2 by a sieve band 6 moving over a suction chamber 8, and are delivered as a fleece to a conveyer band 10, the delivery is facilitated by forming the band 10 as a sieve band passing over a suction chamber 12. The tobacco is removed from the band 2 by a stripper plate 3 and a compressed-air nozzle, and a brushing roller 5 renders the fleece uniform. The chamber 8 may be tapered at 8<a> as described in Specification 314,949, and the band 6 is cleaned by a brushing roller 9. In a modification, the sieve band is formed as a rotary drum, a sector of which is subjected to internal suction. The Specificaton as open to inspection under Sect. 91 (3) (a) states also that a drop of air pressure having a suction effect may be obtained by means of suitably-shaped compressed-air nozzles. This subject-matter does not appear in the Specification as accepted.

Patent GB-239726-A (GB)
Title: The manufacture of new esters of saccharides with unsaturated fatty acids of high molecular weight
IPC: C08B31/04
Filed: 1924-10-18
Abstract: Esters of cellulose with the higher unsaturated fatty acids are prepared by treating the carbohydrate with the acid chloride of the fatty acid. Suitable fatty acids are oleic acid, linoleic acid, linolenic acid, and the unsaturated acids of train oils. Examples are given of the preparation of the linolenic acid ester of hydrocellulose and cellulose, the carbohydrate being heated with the acid chloride of the acid in the presence of pyridine or dimethylaniline. The products are viscous or limpid oils which are soluble in hydrocarbons, also turpentine &c., and are suitable as substitutes for drying oils and in the preparation or manufacture of varnishes, artificial threads, films, plastic compositions etc.; they are rendered insoluble by atmospheric oxidation or by heating, and the drying process may be accelerated by the addition of siccatives; thus, the linoleic acid ester of soluble starch when dissolved in benzine or turpentine with the addition of a small quantity of cobalt linoleate readily dries to a hard elastic insoluble layer, and the corresponding ester of hydrocellulose gives an insoluble product of high melting point when its solution in volatile hydrocarbons is heated in vacuo to 100 DEG C. to drive off the solvent, and grape sugar linoleate readily dries, after the addition of resinate of lead or manganese. Specifications 201,510 and 208,685, [Class 2 (iii), Dyes &c.], are referred to.ALSO:Esters of starch, sugars and other carbohydrates with the higher unsaturated fatty acids are prepared by treating the carbohydrate with the acid chloride of the fatty acid.

An endless track vehicle chassis 12 rotatably supports about a vertical axis a frame 18 which consists of side members 34 supporting a platform 80, a control cab 20 and luffing booms 38 and which is rotatable between the transverse position shown and a position in which the platform extends longitudinally of the vehicle. The booms 38 are luffed by hydralic rams and pivotally support fork members 54 and a clamp jaw 66. In operation, the vehicle is driven in the position shown to engage the fork members beneath a stack of transversely extending timber. Having gripped the timber with the clamp jaw 66, the booms are luffed and the fork members are tilted by rams 58 to bring the timber over the platform 80 on to which it is released. To transport the timber, the frame is rotated through 90 degrees so that the timber extends parallel to the direction of travel. To unload the timber, the frame is rotated back to the position shown, the booms are lowered into contact with the ground and the clamp jaw is closed down. Posts 96 on the platform are pivoted down and the platform is tipped towards the front of the vehicle causing the timber to roll off the platform and down the booms to the ground, Fig. 5 (not shown).

Abstract: 627,053. Locating conductors. CINEMATELEVISION, Ltd., WEST, S. S., and GRIFFITHS, T. Aug. 26, 1946, No. 25451. [Class 37] [Also in Group XXXVIII] To detect the position of vehicles or aircraft over a runway, a plurality of pairs of coils are disposed in the ground below the runway so that they normally have zero mutual inductance, but the approach of a mass of metal increases the coupling between the coils. The coils may be connected to the input and output of an amplifier system such as that described in Specification 574,808, so that coupling causes the system to oscillate. Alternatively, A.C. may be fed into one coil of a pair, and an indicator connected to the other coil. In the latter case, a phase detector may be used to differentiate between the phase of the induced oscillations due to the different " impedance " of vehicles and aircraft. Airfield service vehicles may carry a resonated coil to augment the difference. The coils may be formed partly by an earth return.

Abstract: 246,578. Simplex Conduits, Ltd., and McLoughlin, H. F. Oct. 30, 1924. Switches, quick-action.-In a switch of the dead-centre quick make and quick break tvpe having a coaxially mounted operating-member, intermediate member (which forms one arm of a quick-action compression-spring toggle) and contact-member, the intermediate member has on each face or each axial extremity an abutment adapted to co-operate, with lost-motion, with abutments provided, on the one hand, on the contact-member, and on the other hand, on the operating-member. In the construction shown in Figs. 2 and 5, the switch spindle e which carries the contact-members g is journaled at one end in the casing and at the other end in a sleeve d which takes a bearing in the other end of the casing. The sleeve has fixed upon it, externally, the handle b and, internally, the notched operating-member o. The spindle itself has fixed upon it a driven member i notched like the member c, and the sleeve carries loosely the intermediate member j which constitutes a toggle with the link k trunnioned at l and under the control of the compression spring m. The pivot pin u between these two links projects at both faces of the intermediate member and, in order to hold it in place, it is formed with a central notch or annular groove engaged by the perfcrated end of the link k under the action of the spring m. The notches in the operating and driven members co-operate with the projecting ends of the pivot pin to afford double lost-motion. A spiral spring t around the spindle secured between it and the intermediate member ensures that the contact-member is retained in its full open position in relation to the intermediate member. The open and closed positions are shown in Figs. 2 and 5 respectively. In a modification, Fig. 7, instead of using notched operators and driven members these members are formed with axial projections q, r interengaging with axial projections p on the intermediate member in the manner of a clutch, but providing for double lost-motion.
