Title: Improvement in lubricating oils and process for preparing
Filed: 1934-12-17
Abstract: Highly alkylated aromatic ethers resembling lubricating oils are obtained by condensing a halogenated aliphatic hydrocarbon having more than twelve carbon atoms, in presence of a Friedel-Craft agent, with an aromatic ether free from amino, nitro, carboxyl, aldehydo, hydroxy or sulphonic groups or halogens, having a free nuclear position.  The hydrocarbons which are halogenated are those contained in the middle to higher fractions of petroleum, and those of more than 18 carbon atoms are preferred.  The aromatic ethers may be diaryl, alkyl-aryl, hydroaromatic-aryl, and diarylene, or mixtures thereof, and may contain a plurality of ether groups.  According to examples, chlorinated paraffin, obtained by chlorinating paraffin wax to about 17 per cent chlorine, is condensed with diphenylene oxide, b -naphthyl-ethyl ether, diphenyloxide, anisol, dinaphthylether cyclohexylphenylether, a -naphthylmethyl ether, and dinaphthylene oxide, in various proportions to give products which on isolation and purification have varying viscosities and lubricating properties. According to a further example, products made as described are added in varying proportion to paraffin base lubricating oil to give improved low pour points, the other properties of the oil being practically unchanged.  The halogenated paraffin compounds include those in kerosene, paraffin oils, paraffin wax, petrolatum, ozokerite, ceresin and similar products, and may be chlorine, bromine or iodine derivatives.  The ethers further specified include phenetole, dicresylether, a  and b -dinaphthyl ethers, dibenzylether, cyclohexylphenyloxide, octylphenylether, diphenoxyethane, diphenoxydiethylether and their homologues.  An inert diluent and any of the customary Friedel-Craft agents may be used for the condensation.ALSO:Highly alkylated aromatic ethers useful as lubricating-oils or as pour-point depressors are obtained by condensing halogenated aliphatic hydrocarbons of more than 12 carbon atoms, in presence of Friedel-Craft agents, with aromatic ethers free from deleterious groups such as amino, nitrocarboxyl, aldehyde, halogen, hydroxy or sulphonic.  Suitable aliphatic hydrocarbons are paraffin oils, paraffin wax, petrolatum, ceresin, ozokerite or others contained in the middle to higher fractions of petroleum.  According to the examples, chlorinated paraffins are condensed with diphenylene oxide, b  - naphthylethyl ether, cyclohexyl-phenyl ether, diphenyloxide, anisol, dinaphthyl ether, a -naphthyl-methyl ether, or dinaphthylene oxide.  The products may be added in proportions of 1--2 per cent to paraffin base lubricating-oil to depress the pour point.

Abstract: 878,342. Retractive switches; snap-action switches; switch contacts. TEXAS INSTRUMENTS Inc. Nov. 21, 1957 [Dec. 13, 1956], No. 36376/57. Class 38 (5). The moving contact of a switch is carried by a snap-acting blade spring and co-operates with a contact which is movable laterally of the said movable contact by a member which also actuates the blade spring. As shown, a snapacting spring 30, similar to that of Specification 700,213, carries contacts 53, 56 co-operating respectively with contacts 54, 57 secured to a member 38 which is pivoted at 32. The member 38 is movable counter-clockwise by an actuating force so that a cam 64 thereon forces spring 30 over-centre to change over the contacts. At the same time contacts 54, 57 move laterally from the Fig. 3 to the Fig. 5 position to assist in breaking welds and cleaning the contacts. The member 38 may be restored, on release, by a spring 65 as shown, or by manual or other means. In a modification, Fig. 18, contacts 54, 57 are fixed to the base 31 and contacts 53, 56 actually engage spring contact blades 220, 221, in turn engaging the contacts 54, 57, the blades 220, 221 being carried by member 38 so as to move laterally therewith.

Title: Improvements in or relating to Methods of Roughing Structural I Beams
IPC: B21B39/22
Filed: 1967-08-08
Abstract: 1,184,699. Rolling flanged bars. DE WENDEL & CIE. 8 Aug., 1967 [8 Sept., 1966], No. 36382/67. Heading B3M. A method of roughing I-beams comprises rolling the workpiece in a pass whose crosssection is corrugated and disposed symmetrically about the central axis O of the pass. The workpiece E may be previously shaped in a break-down mill train (not shown) or be a rectangular ingot direct from a blooming mill. In the latter case the number of passes needed will be greater. In one embodiment a preroughened workpiece is passed through a mill stand and then reversed through the same pass (I and II). Between successive passes the rolls are gradually moved together by screwdown means. After the second pass the beams are turned through 180 degrees by at least one hook (R), Figs. 11-15 (not shown). The beams are then passed through the same pass (III). The beam is then moved so that the next pass is through a wider pass. The beam is reversed through this pass and then transferred to an even wider pass formed by the rolls of an adjacent stand. The final pass preferably makes the web straight although a finishing stand may be used (not shown). The beam is turned through 180 degrees after at least two passes throughout the process. In a second embodiment, Fig. 16 (not shown), each stand has three passes and the beam is finished in a finishing stand after the last pass (V). The method is described for 500 mm. and 600 mm. beams.

Title: Improvements in carburettors
IPC: F02M7/17
Filed: 1967-08-08
Abstract: 1,134,379. Spray carburetters. DEUTSCHE VERGASER G.m.b.H. & CO. K.G. Aug.8, 1967 [Aug.29, 1966], No.36389/67. Heading F1B. A carburetter cold-starting device comprises two cold-start fuel feed ducts 17, 18, Fig. 1 connecting a main duct 16, from a float chamber, to two outlets 22, 21 situated one upstream and one downstream of a throttle valve 8, and a suction-actuated slide valve 19 directing fuel to the downstream outlet 21 on starting when there is little suction in the induction tube and to the upstream outlet 22 when the induction tube suction is greater. Operation: When the engine is turned over by its starter, pistons 23, 28 are in the position shown so that the suction acting on outlet 21 lifts fuel from float chamber 3 through control apertures 31, 32, central bore 29, aperture 33, main duct 16, feed duct 17, jet orifice 10 and the righthand end of cylinder 19. The engine accelerator is not operated during starting and stepped cam plate 12 governs the closed position of throttle valve 8 to determine the cold-starting mixture flow rate passing into the induction tube 7. When engine speed increases the increased suction in tube 7 causes piston 23 to slide against the force of spring 24 thereby gradually closing the outlet of duct 17 to reduce the flow through outlet 21. When piston 23 abuts sealing ring 20 flow through outlet 21 ceases. The gradual opening of the outlet of duct 18 by piston 23 allows the fuel flow through cylinder 19, jet orifice 30 and outlet 22 into the mixing chamber to gradually increase to a maximum which remains substantially constant irrespective of the degree of suction in induction tube 7. Any sudden opening movement of throttle valve 8 results in less suction in induction tube 7, piston 23 being thereby moved to the left to reduce fuel flow through outlet 22 and to increase fuel flow through outlet 21. A bi-metal strip 35, which is connected by a heat conductor to the exhaust system, is flexed with temperature increase allowing spring 27 to move piston 28 upwards successively closing apertures 32 and 31 so that when piston 28 reaches its limiting position the cold-start device is cut off. The strip 35 is also connected to the stepped cam plate 12 which ceases to limit the travel of throttle stop screw 11 when the coldstart device is inoperative. In a modification apertures 32 and 31 are replaced by a single long passage connecting the bore 29 to the float chamber 3.
