Patent GB-448424-A (GB)
Title: Improvements in or relating to lubricants and methods of making the same
IPC: C10M137/04
Filed: 1934-10-26
Abstract: Lubricants for extreme pressure or other use are obtained by mixing a halogenated organic ester of a phosphorus acid with a viscous hydrocarbon oil.  1--10 per cent of ester is suitable. Fatty oils, and soaps, or other thickening agents may be added. The halogenated radicles may be methyl, methylene, methine, phenyl, naphthyl, anthracyl, and their homologues.  Esters specified includes halogenated tri-butyl phosphate, halogenated triphenyl phosphate, and halogenated monobutyl-diphenyl phosphate.  In examples: 1 lb. of chlorinated tricresyl phosphate containing 3,1 per cent of chlorine is dissolved in 99 lb. of Pennsylvanian lubricating oil; and 3 lb. of chlorinated tributyl phosphate containing 5,9 per cent of chlorine is mixed with 97 lbs. of mid-continent lubricating oil.

Abstract: 648.124. Control of A.C. motors. SINGER MANUFACTURING CO. Nov. 26, 1948, No. 30805. Convention date, Sept. 8. [Class 38(iii)] A control system comprises an induction motor with polyphase and single-phase windings, the latter having the greater number of poles, manually selective means for connecting the polyphase winding to a supply-source,' automatic means for disconnecting the polyphase winding from the source and connecting the single-phase winding to one phase of the source, and motor-operated means for disconnecting mined number of revolutions of the motor. the single-phase winding after a predeter- When a switch 25 is manually closed and held by a latch 29, a contactor 5 is operated to connect a polyphase stator winding 2 of a squirrel cage induction motor 1 to supplylines L1, L2, L3. Contacts 19 are opened and contacts 18 closed when a motor-driven cam 20 displaces follower 22, so that the contactor 5 is opened to disconnect the winding 2 and contactor 11 closes to energize single-phase stator winding 3 from lines L2, L3. When the change of windings is effected the motor is regeneratively braked' since it runs at above the synchronous speed determined by the winding 3 which has a greater number of poles than the winding 2. The load is afterwards driven at the low speed set by the winding 3 until a motor-driven trip cam 30 releases the latch 29 to disconnect the motor which finally runs into a mechanical stop. Due to its single-phase excitation the motor does not exert a driving torque at standstill in the event of power not being removed before the motor reaches the stop.

Title: Process for treating a crude benzene with purified coke oven gas
IPC: C07C7/163
Filed: 1956-10-12
Abstract: In a process for purifying benzene with purified coke oven gas (see Group XIII), the purified coke oven gas is compressed to a pressure above 20 atmospheres, mixed with recycled stock gas and the benzene to be purified and heated to a temperature of about 200 DEG  C., the mixture being then passed to an evaporator in which resins formed are separated and from which a mixture of gas and vaporized benzene is passed to be heated to about 350 DEG  C. and led over a hydrogenating catalyst.

Abstract: 430,699. Change speed gearing. MAYBACH - MOTORENBAU GES., Friedrichshafen-on-Bodensee, Germany. Nov. 1, 1934, No. 31373. Convention date, Nov. 1, 1933. [Class 80 (ii)] Relates to change-speed gearing having at least three pairs of gears 7, 11 and 8, 12 and 9, 13 in constant mesh with single-acting change clutches 17, 18, 19, 20 adapted for quick throwing over and having inclines on the ends of the clutch jaws to prevent engagement until there is a change in relative speed, as described in Specification 298,186, [Class 80 (ii)]. The pair of clutches 17, 18 on parallel shaft sections 1, 4 are adapted to be thrown over into operative position alternatively in the same direction by an intermediatelypivoted lever 21 as described in Specification 347,570, there being no intermediate neutral position. An engine clutch on a vehicle is unnecessary since the clutches are changed without shock with throttle manipulation on some changes. The pair of clutches 19, 20 are similarly constructed and operated similarly by a lever 22, but the clutches 19, 20 slide oppositely into engagement to the clutches 17, 18 on the same shaft lines. The driving- shaft line comprises two splined shaft sections 1, 2 ending within the boss of the gear 8, and in the arrangement shown, there is a third or tail shaft section 3 with a gear 10 loose upon it. The countershaft line comprises two splined shaft sections 4, 5 ending within the boss of the gear 12 and a third splined section 6 rigid with the gear 13. A double tooth-repelling clutch 45 slides on a splined part of the tail shaft 3 operated by a lever 46, and a pinion 14 slides on the shaft section 6 operated by a further lever 47. The first speed is a quadruple reduction through train 7, 11, 12, 8, 9, 13, 14, 10. Second is through double reduction train 7, 11, 14, 10. Third is through train 7, 11, 12, 8. Fourth is through train 9, 13, 14, 10. Fifth is through train 7, 11, 13, 9. Sixth is through train 8, 12, 14, 10. The seventh is direct drive. The eighth is an overdrive through train 8, 12, 13, 9. Six forward speeds are usually enough, and the fourth and sixth speeds are conveniently omitted. Four reversed drives are possible all from the pinion 4 to the gear 10 through stepped idlers 27, 28. The changes are effected through double-acting spring striking devices 37, 38, 48 either by hand or by suitable air pressure cylinders, not shown.

Abstract: 1314549 Workholders for saws PARAMOUNT TEXTILE MACHINERY CO 30 June 1970 [1 July 1969] 31557/70 Heading B5L A method of severing a workpiece with a cutter which is moved transversely through the workpiece to form a kerf, and is then returned through the kerf includes the step of spreading the cut portions of the workpiece prior to return of the cutter. In apparatus for performing the method, a workpiece 18, Fig. 1, supported on shelf portions 56<SP>1</SP>, 58 of a slide 20, and of a similar slide 22, Fig. 2, is cut transversely by a rotating saw blade 12 advanced by a slidable base 14, Fig. 1. After cutting, hydraulic fluid under pressure is admitted to cylinders 94 to cause vices 26, 28 to by urged downwardly to clamp the cut workpiece portions to the slides 20, 22. Pressure fluid admitted to a cylinder 106 on slide 20 causes a piston-rod 108 secured to slide 22 to advance to separate the slides and clamped workpiece portions, whereupon the saw blade is returned between the separated portions. A stop member secured to a fixed part of the machine frame limits spreading of the slides and ensures that they return to their original positions, e.g. for measuring purposes, when the piston-rod 108 is withdrawn. The blade 12 may be replaced by a reciproeating blade and/or the workpiece may be moved transversely rather than the blade. The slide 22 may be replaced by a conveyer for removing cut-off workpiece portions.
