Patent GB-689731-A (GB)
Title: Lubricating compositions
Filed: 1945-08-09
Abstract: An extreme-pressure, detergent, anti-corrosive lubricating composition for use at high temperatures and for crankcase and gearbox lubrication comprises a major proportion of an oil base and a minor amount of each of three separate components; viz, an organic halogen compound, an organic sulphur compound, and a salt or ester of an organic sulphonic acid.  The compounds should be oil-soluble or oil-miscible and have a vapour pressure less than atmospheric at 140 DEG C, preferably 170 DEG C.  As halogen compound virtually any halogen compound having the desired vapour pressure may be used.  As sulphur compound may be used organic sulphides or polysulphides of the same or different organic radicles whether aliphatic, aromatic, or mixed aliphatic-aromatic, mercaptans, thio phenols, thio esters, amides or anilides or thio urea, including reaction products of phosphorus pentasulphide or organic compounds, and including halogenated sulphur compounds.  As sulphonic acid derivatives may be used sulphonic esters or salts such as the calcium salt of petroleum sulphonic acid.  The proportions contemplated are up to 20 per cent, preferably 0.1 to 10 per cent of halogen and sulphur compound together, and up to 10 per cent, preferably 0.01 to 2 per cent, of the sulphonic salt or ester.  The composition may be used as a grease if a thickening agent such as a soap is added.

Title: Process for the manufacture of adipo-dinitrile
IPC: B01J23/70
Filed: 1960-06-10
Abstract: Nickel catalysts activated with an alkali-metal oxide and supported on a carrier, e.g. kieselguhr or silica gel, are used for the hydrogenation of 1:2-dicyanobutane to adiponitrile.  The catalyst may be prepared by impregnating natural kieselguhr with an aqueous soultion of nickelous chloride, treating at 70 DEG -80 DEG C. with a sodium carbonate solution, drying and reducing with hydrogen at 350 DEG C.  Ferric, aluminium, potassium and sodium oxides are present with the nickel and silicon dioxide. Hydrogenation of adiponitrile to hexamethylene diamine may be effected in the presence of Raney cobalt.ALSO:Adiponitrile is prepared by treating 1 : 2-dicyanobutane, dissolved in a polar organic solvent, with hydrogen at a temperature between 200 and 400 DEG C., under a pressure above 100 atmospheres, in the presence of a nickel catalyst activated with an alkali metal oxide and supported on a carrier.  The reaction mixture is in the form of a solution and dioxan is preferred as the solvent.  The catalyst carrier may be kieselguhr or silica gel, and a nickel catalyst containing metal oxides prepared by impregnating kieselguhr with aqueous nickelous chloride, treating with sodium carbonate, drying and reducing with hydrogen at about 350 DEG C., is used in examples.  The product may be further reduced in a second stage, e.g. in the presence of Raney cobalt, to hexamethylene diamine. Specifications 900,356 and 900,358 are referred to.

Abstract: 852,764. Retractive switches. CUTLERHAMMER Inc. June 27, 1958 [June 27, 1957], No. 20722/58. Class 38 (5). [Also in Group XXII] A switch for an electric power tool has a trigger 26 pivoted at 38 and connected at 40 to a latch member 42 having a portion normally engaging an aperture 44 in a slidable member 46. When the trigger is released, Fig. 2, it is biased clockwise by a spring 48 connected to the latch and by a spring 54 connected to a portion 52 of member 46. When depressed to a second position, Fig. 3, the latch is pulled to the left and the member 46 is slid to the left to allow the switch 28 to close. Further depression of the trigger to the Fig. 4 position causes it to engage a part 66 of the latch to disengage the latter from the aperture 44 to allow the member 46 to be pulled to the right by spring 54 to re-open the switch. The latch may have a portion which presses against the side of spring 48 to increase the spring opposition to such extra movement of the trigger. The latter may be held in the Fig. 3 position by depression of a button 62 into an aperture 64 in the trigger.

Patent GB-577676-A (GB)
Title: Improvements in or relating to the production of reinforced plastic articles
IPC: B32B27/00
Filed: 1943-12-15
Abstract: Reinforced plastic articles of complex or curved form are produced by moulding under heat and pressure sheets of creped material which have retained the greater part of their hygroscopic moisture and incorporate a phenolic resin in the A stage or a cresylic resin in a similar stage, i.e. fusible and soluble, the sheets being assembled in stacks with the crimps of adjacent sheets mutually inclined and the pressure applied intermittently. Paper made from sisal fibres with long fibres well felted together is preferably used, urea being introduced into the pulp and the paper treated prior to the creping process by wetting with starch or dextrine.  The degree of crimping is such that it is not wholly removed in the moulding process, e.g. a 100 per cent crimping is given to the paper which when stretched in the mould retains 15 per cent crimping.  One quantity of paper is coated with 35 per cent by weight of a thermosetting plastic such as a phenolic or cresylic resin and another quantity with 70 per cent by weight. The amounts may be smaller, e.g. 20-30 per cent and 60-70 per cent respectively.  The paper blanks having the lower resin content are enclosed in sandwich form between two lots of blanks having the higher resin content, each paper blank having its crimps in a direction at an angle, e.g. 45 degrees, to adjacent sheets, the change of angle being continuous in the same direction throughout the stack.  The whole is subjected to pressure in a press of 200-350 lbs./sq. in. at a temperature of 100-135 DEG  C., preferably 135 DEG C.  In the initial stage, the pressure is released and the dies removed several times.  In a further example, a felted core of sisal fibres containing 35 per cent phenolic or cresylic resin is enclosed between two sets of several blanks of crepe paper containing 70 per cent resin, each blank being at an angle to the adjacent sheet, and subjected to pressure between male and female dies to give the desired mould.

Title: Improvements in the production of slabs or sheets of material from fibrous pulps
IPC: D21J1/00
Filed: 1944-11-01
Abstract: 602,168. Moulding slabs &c. from pulp. BERNHEIM, F., PICKSTONE, R. E., and COLMORE, C. A. G. Nov. 1, 1944, No. 21361. [Class 87(ii)] Apparatus for forming slabs or sheets from fibrous pulp comprises a horizontally disposed, shallow, box-like mould 1, corresponding in width and depth to the desired width and thickness of the finished sheet, pulp feeding means 8, 9 and, fitting into the shallow mould, a horizontally reciprocable hollow plunger 4 with a perforated pressure face 10. Successive batches of fibrous pulp are fed on to the mould floor and then swept along it by the plunger so that the pulp, with the fibres mainly upright, is piled up and pressed against the end of the mould, or against the pulp already compressed therein, and is thus formed into a transverse section of the width and thickness of the finished sheet, the moisture draining away through the perforated face 10. The forward end of the plunger may be corrugated vertically to accentuate the adhesion between the fresh batches of pulp and the pulp already moulded. The rear end of the plunger has a water outlet 12. One or more of the walls of the mould may also be perforated. Connection may be made to a source of vacuum to draw away the moisture. The mould has a removable cover 14 held down by a clamp 15, and may be mounted so that it can be turned over on its longitudinal axis to facilitate the removal of the moulded sheet. The plunger 4 may be actuated by a double acting ram 5 reciprocable in a hollow cylinder 6, and the movement of this ram may be reversed at different points to give it a variable stroke to accommodate the growing size of the sheet, these reversals being effected by auxiliary piston means controlled by the fluid pressure in the cylinder 6. Alternatively the ram may be operated by an electrically driven rack and pinion motion and a variable stroke achieved by automatic switchgear. In a third arrangement the stroke of the plunger may be constant and the mould may be slidably mounted and yieldingly held in place so that as the sheet grows in length the mould recedes under the increasing pressure exerted by the plunger.
