Patent GB-713186-A (GB)
Title: Lubricating oil compositions
Filed: 1951-07-10
Abstract: A lubricating oil comprises a major proportion of a mixture of hydrocarbon oil and polyalkylene glycol polymer, in a ratio between 1 : 3 and 3 : 1, and a soluble metal salt of an alkyl-substituted phenol or cresol containing 4-20 carbon atoms in at least one alkyl group.  A metal salt of a dithiocarbamic acid is preferably also present.  The polymers may be prepared from ethylene, 1, 2-propylene, butylene or higher alkylene oxides or their mixtures or the corresponding alkylene glycols, and include derivatives of the polyalkylene glycols such as ethers, esters or ether esters.  They may be prepared as described in Specifications 584,367, 601,604, 634,183 and 651,727.  Preferred metal phenates p  are sulphurized polyvalent metal alkyl phenates.  Metal salts of dialkyl diphenol sulphides, metal phenates from high molecular weight alkyl phenols, alkaline earth metal phenates, metal salts of alkyl phenol thioethers and disulphides, and metal salts of condensation products of low molecular weight aldehydes with alkyl phenols are also suitable. Polyvalent metals, e.g. alkaline earth metals, Zn, Cd, Al and Sn, are preferred, but Na, K, and Li salts may be used.  The amount of metal phenate is about 1-10, preferably 2-5 per cent. of the composition. The dithiocarbamates have the formula <FORM:0713186/III/1> where M may be any of the metals listed above, a is an integer, at least one R is an oil-solubilizing group, preferably a hydrocarbon group, while one may be hydrogen.  Examples are Ca, Pb, Zn and Cd dibutyl dithiocarbamates, zinc dicetyl, methyl octyl, monocetyl, butyl amylphenyl, and dibenzyl dithiocarbamates, and calcium di (cyclohexylphenyl) dithiocarbamate.  The amount may be about 0.1-1, preferably 0.2-0.5 per cent. of the final composition.  The hydrocarbon oil may be a straight mineral oil or a distillate, a refined oil, a white oil or a hydrogenated synthetic, e.g. from olefin polymerization or carbon monoxide hydrogenation.  In an example, the polymer is a polypropylene glycol monoisooctyl ether monoacetate of 550 M.W., the oil, of equal weight, a refined distillate cut from naphthetic crude, the phenate a sulphurized calcium, cetyl phenate, and the dithiocarbamate the zinc di-n-butyl salt.  Other examples employ a medicinal white oil, polypropylene glycol monobutylether, barium cetyl phenate, and zinc diethyl diethyl dithiocarbamate.

Abstract: 554,307. Riveting; stud fastenings. AVIATION DEVELOPMENTS, Ltd., and SPOONER, R. A. W. Dec. 20, 1941, No. 16461. [Class 44] In a stud fastening for securing perforated members together, applicable generally but particularly adapted for holding plates during riveting, and of the kind described in Specification 524,297, in which a ball or balls 7 or other member is normally held projected from the tubular body 1 by a movable rod 8 within the body and is allowed to collapse inwards to release the device when rod 8 is axially displaced from normal position against spring action, the device is arranged so that inward collapse occurs when the rod is moved in either direction from a normal mid-position. The device can thus be inserted by pressure on rod 8, or removed by a pull on a ring 13 carried by the rod. As shown, a coiled compression spring 14 surrounds tube 1 near the head 3 and its ends extend inwards through slots 4, 5 in the tube into recesses 11, 12 in the rod. The rod is thus held in, and returned to the normal position displacement from which allows ball 7 to move inwards into one or other of two recesses 9, 10.

Abstract: 209,023. Planer, V. Dec. 28, 1922, [Convention date]. Drawings to Specification. Controlling and actuating indicators.-In a station or other indicator, which may be controlled by wireless, bands bearing letters are selectively positioned to spell out the desired word by successive sets of impulses transmitted by a keyboard having a key for each letter of the alphabet. The depression of a key sends the corresponding number of impulses and its release sends an impulse over a separate circuit to operate a selector to bring the magnet controlling the next band into the line circuit. When wireless control is used, the bands are positioned by interrupting the wave or varying its frequency. With a combination of these two methods the selector may be omitted.

Abstract: 1,036,933. Windscreen wiper arms. TRICO PRODUCTS CORPORATION. April 30, 1963 [April 30, 1962], No. 16975/63. Heading A4F.  In a windscreen wiper arm assembly comprising a wiper arm 20 pivoted to a mounting head 19 and means for biasing the arm towards the windscreen, arresting means confine the pivoting movement to towards the windscreen only. The wiper arm 20 is connected by a pivot pin 27 to the mounting head 19, and is biased towards .the windscreen by spring 33. The arresting means comprises a rod 46 pivotably connected at one end to the mounting head and having its opposite end peened over to retain a washer 50 and a spring 51 which bears against a locking member 41. The latter comprises an angle member 43, ,44 having ears 42 (Fig. 6, not shown) engaging in trapezodial slots 38 in the wiper arm housing 24. The bias of the spring 51 forces the ears 42 against the side walls 39 of the slots 38, so canting the locking member 41 with respect to the rod 46 and causing the edge of the aperture 45 therein to bite into the rod 46- and prevent rotation of the arm 20 away from the windscreen. To pivot the arm 20 away from the windscreen, tab 44 is depressed to release the locking member by causing the ears 42 (Fig. 6, not shown) to rest against the other side walls 40, against the bias of the spring 51, so permitting anti-clockwise rotation. A modified embodiment is described in which the wiper is biased towards the windscreen by a spring cartridge.

When R6 represents aralkyl, the phenyl nucleus may be mono-, di-, or tri-substituted by chlorine, methoxy, methylenedioxy, methyl, trifluoromethyl, amino or nitro groups.  In a similar manner R1 may represent substituted phenyl.  In a modification of the above process 2-R1-3-amino- 5-R3- pyrazole- 4-carboxylic acid amide is replaced by the nitrile, reacted with the derivative of the acid R6,COOH, converted into the amide followed by ring closure.  Intermediate compounds having the formula:  <FORM:0937724/IV(a)/2> are obtained by eliminating water from 2-R1-3-(R6-CONH)-4-carboxy-pyrazoles, e.g. with acetic anhydride.  These compounds may be reacted with ammonia to obtain the acid amide.  2-(b -Hydroxyethyl)- 3-amino-4-carbethoxypyrazole is obtained by heating ethoxymethylene cyanoacetic ester with b -hydroxyethyl hydrazine. 2-[11-Ethoxy-butyl-(31)] -3-amino-4-carbethoxy pyrazole is obtained by heating ethoxymethylene cyanoacetic ester with 1-ethoxy-butyl-(3)-hydrazine. 2-a -Pyridyl-3-amino- 4-carbethoxy-pyrazole is obtained by heating ethoxy-methylene-cyanoacetic ester with 2-hydrazino-pyridine. 2-Isopropyl-3-[a -ethoxyb -(p-chlorophenyl) -ethylidene-amino]-pyrazole-4-carboxylic acid amide is obtained by forming the imino ether hydrochloride from p-chlorobenzyl cyanide and dry HC1 and boiling this with 2-isopropyl-3-amino-4-carbonamido pyrazole. 2-Isopropyl-3-(p-chloro-phenyl-acetylamino)-4-pyrazole-carboxylic acid nitrile is obtained by reacting 2-isopropyl-3-amino-4-cyano-pyrazole with p-chloro-phenylacetic acid chloride.  2-Isopropyl-3- (p-chlorophenyl-acetylamino)-4-carboxy-pyrazole is obtained by reacting p-chlorophenylacetic acid chloride with 2-isopropyl-3-amino-4-carboxy pyrazole.  1-Isopropyl-4-oxo- 6-(p-chlorobenzyl)-pyrazolo-[3,4-d] oxazine is obtained by heating 2-isopropyl-3-(parachlorophenyl-acetylamino)-4-carboxy-pyrazole with acetic anhydride. p   Said compositions containing compounds of the first mentioned formula and having coronary-dilating action are administered as tablets or dragees or in liquid form as solutions, suspensions or emulsions.
