Title: Mechanical transmission for traction purposes
IPC: B61C9/30
Filed: 1957-06-18
Abstract: 854,824. Change-speed control positive clutches. ZEMAN, K. June 18, 1957 [June 30, 1956], No. 19185/57. Class 80 (2). [Also in Group XXXI] In a change-speed gear driven directly by a combustion turbine, the gears are synchronized for engagement by a servo-mechanism controlling the input gases to the turbine and/or braking the turbine rotor. A turbine 1 drives a gear-box 3 through a coupling 2 and provides a drive to universal joints 25 connected to the axles of a railway vehicle. A regulation device 5 sensitive to speed and torque is connected to a gear-shift servo-mechanism 6 which also controls the application of a brake 4 on the gear input shaft, and controls the supply of gases to the turbine by throttling or by-passing by valve 7. When a change of gear is required as sensed by the device 5 the turbine is throttled and braked, the gear is engaged and the turbine accelerated for synchronism by the servomechanism 6. The gear-box 3'comprises paral, lel forward 8 and reverse 9 shafts driven from the coupling 2 and geared together by gears 10, 12 which are engageable with the shafts by dog clutches 11, 13. Each shaft 8, 9 carries gears 14, 15, 16 meshing with gears 20, 21, 22 on a shaft 26 having a gear 23, at its end, meshing with a gear 24 on the output shaft 27 carrying the universal joints 25. All the gears are carried on large diameter tubular shafts carried in bearings such as 48, 49 close to the gears to minimize distortion under load. The tubular shafts of the gears on the shafts 8 and 9 form double dog clutches 50, 51 engageable by sliding clutch members 52, 53 to eliminate end thrust. The walls of the box 43, 46 supporting the bearings form oil baths for each individual gear and also serve to strengthen the gear casing.

Abstract: 614,400. Photographic plates. RELIEPHOGRAPHIE, SOC. POUR L'EXPLOITATION DES PROCEDES DE PHOTOGRAPHIE EN RELIEF M. BONNET. July 26, 1945, No. 19187. Convention date, Dec. 12, 1942. [Class 98 (ii)] A paper is affixed to a glass plate or other plane and rigid surface by means of a glue such as gelatin and a photosensitive emulsion is then applied to the paper, the paper being slightly smaller than the plate so that the edges of the paper may be sealed with the emulsion. The product can be subjected to treatment in baths and drying without being subject to elongation or shrinking and without losing its evenness, and is suitable for use with lenticular screens, associated, for instance, with taking parallax panoramograms, or for colour photography on paper. The Specification as open to inspection under Sect. 91 comprises also the attachment of an already sensitized paper to a glass plate or other plane and rigid surface, and the application of a layer of varnish or other white or slightly tinted coating to such rigid surface and then the emulsion, no paper being used.

Patent GB-1108484-A (GB)
Title: A method of producing perchloromethyl mercaptan
IPC: C07C/
Filed: 1965-05-06
Abstract: Perchloromethyl mercaptan is prepared by chlorination of carbon disulphide at normal or superatmospheric at 0 DEG -46 DEG  C., in the absence of oxygen, whereby gaseous or liquid chlorine is introduced into an aqueous solution containing 5-38% by weight HCl, based on the weight of the solution, the HCl concentration being maintained within said range throughout the reaction, and chlorination is effected with intensive mixing of the carbon disulphide, aqueous solution and chlorine.  Sulphuric acid is formed as a by-product of the reaction and it is preferred to add further amounts of sulphuric acid to the reaction mixture. Chlorination may be effected in the presence of a catalyst which provides a cation of Pb, W, Mo, Co or Ni. The reaction may be carried out in the presence of a solvent for chlorine and an emulsifier to assist mixing the reactants.  As HCl is formed in the reaction the required HCl concentration may be maintained by the addition of water or dilute sulphuric acid.

Title: Purification of electrolyte used in electrolytic machining
IPC: B03D1/24
Filed: 1963-05-17
Abstract: In electrolyte machining, the machining electrolyte which is fed to the machining work zone under pressure contains a foaming agent and a gaseous fluid is maintained under pressure in the work zone and is then passed to a reservoir where the electrolyte effervesces at reduced pressure so as to form a foam containing impurity particles such as matter eroded from the workpiece, and the foam is removed from the electrolyte surface.  As shown, electrolyte from a reservoir 10 into which a foaming agent such as liquid or powdered soap is introduced at 12 is moved by a pump 14 in which also air is drawn along conduit 16 into the electrolyte and then optionally through a filter 24 to the enclosed work zone 28.  The used electrolyte then passes through a constriction 34 to an open reservoir 32 containing perforated screen baffles 38 and the resultant foam overflows into a sump 36 while the clean electrolyte siphons back into the reservoir 10 where vertical baffles 42 retain any residual foam to avoid its recirculation by the pump. The foam in the reservoir 32 may alternatively be blown or raked away or a conveyer or vibrating inclined shoot may be provided for its removal. <PICT:0982122/C6-C7/1>

Title: Improvements relating to the transfer of liquids through pipelines
IPC: F16K31/12
Filed: 1960-06-07
Abstract: 939,550. Controlling distribution of liquids. BRITISH PETROLEUM CO. Ltd., and G. C. BAMBURY. June 5, 1961 [June 7, 1960], No. 19924/60. Class 135. A pipeline system for passing two or more liquids in sequence so that intermixing is minimized comprises two sections, a non-flexible and relatively straight section 2 and a section 1 either flexible or containing a sharp bend, a chamber 12 for one or more " separating pigs " situated adjacent to the junction of sections 1 and 2, means for removing liquid from section 1 and means for transferring the pig or pigs between section 2 and the chamber 12. The pipeline may connect a ship to the shore. The section 1 is connected to a ship's pump 3 via manifold 4 comprising vacuum pressure gauge 6, purge and exhaust system 7 and chamber 8. Section 2 is connected to the shore installation via manifold 5 comprising vacuum pressure gauge 9, purge and exhaust system 10 and chamber 11. When liquids are pumped from ship to shore, a first liquid is pumped by pump 3, a pig 16 being in position in chamber 12. Pump 3 is then shut down and an inert gas introduced into section 1 at a pressure of about 10-15 p.s.i.g. The shore pump is then operated until all the liquid in section 1 has been forced into section 2. Air is introduced, through a small bore pipeline from receiver 15 by compressor 14, into pig chamber 12 so that pig 16 moves into the adjacent end of section 2. Section 1 is then filled with the second liquid and pumping restarted, the inert gas being vented via system 7. When pig 16 reaches the shore manifold 5, as shown in Fig. 4, further flow is obstructed, the shore equipment can then be operated so that a small amount of the higher grade liquid (either first or second liquid) passes into the second product. If it is undesirable that either liquid should contaminate the other the shore equipment may be drained with pig 16 still in position. The pig 16 may be returned to chamber 12 at any time but preferably soon after it has been retrieved in chamber 11. Liquids may be pumped from shore to ship in a similar manner. The pig may be forced out of chamber 12 by a piston held captive by a wire rope, or the chamber could be capable of holding more than one pig. If necessary more than two liquids can be passed in sequence along the pipeline by the use of either one or more pigs. The line can be flushed by a portion of the second liquid. This portion may be separated from the main body of the second liquid either by a second pig or by a hollow sphere of flexible material (e.g. polyvinyl chloride) filled with a liquid, this sphere being released from the chamber 8.
