Title: Improvements in or relating to pitman arm drag links, and assemblies and steering linkages including the improved pitman arm drag links
IPC: B62D7/16
Filed: 1944-09-26
Abstract: 599,692. Motor vehicle steering. THOMPSON PRODUCTS, Inc. Sept. 26, 1944, No. 18360. Convention date, April 24. [Class 79 (v)] [Also in Group XXV] A pitman arm drag link has a boss at one end for attachment to the steering box and a tubular housing in spaced offset relationship at the other end in which are located a pair of closely spaced ball studs, the shanks of which project through a slot in the housing and are secured to tie rods whose other ends are secured to the steering arms, thus eliminating the usual drag link and track rod. The layout is particularly suitable for vehicles having independently sprung steering wheels. The pitman arm 12 has a boss 10 at one end and a transverse tubular housing 11 at its other end containing, ball studs 20 connected via conventional tie-rods 24 and studs 25 to the steering arms of the wheels. The ball studs 20 are located between four seating members 16, two of which are placed together between the two ball studs, and are maintained in contact with the ball studs by compression springs 21 which are located on tubular supports 22. The supports 22 also act as stops to prevent the ball studs from moving too far along the tube whereby one might drop out of the end of the slot 11c which is of keyhole shape with its enlarged end big enough to permit passage of a ball stud during assembly. A grease nipple 23 may be provided and the seating members 16 may each be drilled as at 16c for lubrication purposes. The slot 11c may have a felt-lined dust cover 27. In alternative forms, not shown, the arm 12 may be connected to the tubular housing 11 at one end of the latter, or in the layout shown in Fig. 1, the arm 12 instead of being integral with the tubular housing 11 may be secured thereto by a clamp.

Patent GB-748037-A (GB)
Title: Process for extracting sulphur from fumes containing sulphuretted hydrogen
IPC: C01B17/05
Filed: 1953-07-03
Abstract: A gaseous mixture comprising oxygen and hydrogen sulphide is contacted in an oxidation stage wth an aqueous solution of an alkali metal or ammonium polysulphide at a pressure of 2-6 atmospheres and a temperature of 80-95 DEG C. and the resulting polysulphide soltion of increased sulphur content is heated to a temperature above 120 DEG C., preferably 120-130 DEG C. and a pressure of 2-6 atmospheres, preferably the pressure in the oxidation stage, thereby producing liquid sulphur and a polysulphide solution of decreased sulphur content which is recycled, after cooling, to the oxidation stage. The hydrogen sulphide employed may be obtained in the purification of coal gas by passing crude coal gas through weak ammonia liquor and then heating indirectly with steam.  The gases passing from the oxidation stage may be washed with the cooled polysulphide before this is passed to the oxidation stage.  The oxidation reaction and subsequent washing of the gases may take place in a single column, the temperature of which falls from 80-85 DEG C. at the bottom of the column to 30-40 DEG C. at the top of the column.  The gases leaving the column may be further washed in a separate scrubber under the same pressure as the column using coal gas purification liquor from a hydrogen sulphide scrubber.  The volume of circulating polysulphide solution may be maintained constant by bleeding off a portion and adding to the gas purification liquor prior to hydrogen sulphide desorption.  The polysulphide liquor may be heated indirectly by steam and the resulting decomposed solution cooled indirectly first by heat exchange with polysulphide solution prior to heating and then with cold water.

Abstract: The invention comprises compounds of the formula <FORM:1001954/C3/1> where R is a hydrocarbon or cyanoalkyl radical and R1 is the same or hydrogen, and m is 1, 2, 3 or 4, and linear polymers thereof.  The compounds are prepared by the reaction of a compound <FORM:1001954/C3/2> with an amine R1NH2.  Temperatures from 20-200 DEG  C. are suitable, and a catalyst, e.g. ammonium or cupric chloride may be used.  An inert solvent, e.g. an aromatic hydrocarbon, is advantageous.  The compounds are polymerized by heating them to 125-175 DEG  C. with 0.005-1% by wt. of a basic catalyst, e.g. KOH. These polysiloxazanes can be mixed with various fillers and be peroxide-cured to give rubbers, or used to treat fillers for use with other polysiloxane materials, or to render surfaces water-repellent. The preparation of 1,5-dichloro1,1,5,5 - tetramethyl - 3,3 - diphenyl trisiloxane is described.

Abstract: 746,347. Rotary pumps. UNITED STATES STEEL CORPORATION. June 25, 1954, No. 18783/54. Class 110(2) One or more pumps 19, 20, used in welldrilling installations, are driven by a number of engines 13, 14, through easily-removable variable-speed transmissions 25, 29, 16, 17 or single-speed apparatus. The transmission 25 is bolted to a base or skid 21 and is coupled to the engine 13 by a shaft 16, power being taken off through a belt drive 26, 27, 28. A separate variablespeed transmission 29 is also bolted to the base 21 and transmits power from the engine 14 through a shaft extension 17 and a rope drive 31, 32 to the pump 20. The transmission can embody any standard mechanism which can give at least two forward speed ratios. The variable speed transmissions may each be mounted on its own base or skid, Figs. 3, 4 (not shown), the two skids being carried on another skid. Other modifications for the mountings of the transmission casings are described in the Specification. Fig. 7 shows the plant with the variable-speed transmissions removed, the engine shafts 19, 20 being coupled to the pumps through stub shafts 42, 43 and belt drives 46, 47. Base plates A, bearings 38, 39 and shaft 42 are constructed as a unit which bolts on to a skid 21, in the same bolt holes as the two-speed transmission 25, thus facilitating an easy changeover. The other pump 20, is driven by units on a base plate B, similarly arranged. One pump can be driven by a variable-speed transmission, and one through a stub shaft. Specification 607,874 [Group XXVIII], is referred to.

Patent GB-575138-A (GB)
Title: Treatment of chemical wood pulp and the production of viscose therefrom
IPC: D01F2/08
Filed: 1943-11-15
Abstract: A small proportion of a cation active quaternary ammonium compound is incorporated in chemically refined cellulose pulp, containing not more than 0.15 per cent of ether extractable matter, or at any subsequent stage in the manufacture of alkali cellulose or viscose prior to the completion of the xanthation, in an amount of 0.01 to 0.20 per cent based on the weight of the bone-dry pulp.  The cation-active compound may be lauryl trimethyl ammonium chloride or bromide, cetyl trimethyl ammonium bromide, lauryl methyl morpholinium bromide, lauryl methyl piperidinium bromide, lauryl dimethyl cyclohexyl ammonium bromide, lauryl pyridinium bromide.  Preferably compounds are used in which the nitrogen atom is linked to one or more aliphatic chains of 7 to 20 carbon atoms and to one or more cyclo aliphatic rings of which the nitrogen is either part or in close proximity.  The pulp may be treated with the agent while in suspension prior to sheet formation or the pulp sheet may be treated prior to drying.  The agent may be added to the cellulose during the operation of steeping with caustic soda in the preparation of alkali cellulose or it may be added during the shredding operation.  The presence of the cation active substance facilitates disintegration of the alkali-cellulose in the shredding operation and leads to the formation of shredded crumbs of low apparent density.  It leads to more uniform and complete xanthation and to a viscose largely free from undissolved or partly dissolved fibres and gels.  Filtration is thus facilitated and shortened.  Smaller proportions of carbon bisulphide may be used in the xanthation.  The dispersal of mineral oil in the viscose for the production of filaments of subdued lustre is facilitated by the presence of the cation active substance.
