Title: Lubricants
IPC: C07F7/00
Filed: 1957-04-23
Abstract: Lubricating oil compositions (see Group III) comprises a synthetic lubricating oil consisting of carbon, hydrogen, oxygen and silicon, a base oil-compatible reaction product of 1 mole of a titanium tetraester with 1/2 to 4 moles of a C2-24 glycol, and a base oil-compatible dicarboxylic acid.  The oil may be a polymethyl, polyethyl or polyphenyl siloxane having a viscosity of from 50 SUS/100 DEG F. to 250 SUS/210 DEG F.  The titanium compound may be prepared as described in U.S.A. Specification 2,643,262 from an alkyl, aryl, alkaryl, cycloalkyl, alkoxy or mixed tetratitanate and a (preferably 1, 3-) glycol which may be halogen-substituted.  The reaction products may be in a monomeric or polymeric form.  Preferred dicarboxylic acids have 20 or 2 to 12 carbon atoms.  Specification 866,054 also is referred to.ALSO:Lubricating oil compositions comprise a lubricating oil, a base-oil-compatible reaction product of 1 mole of a titanium tetraester with 1/2 to 4 moles of a C2-C24 glycol, and a base-oil-compatible dicarboxylic acid, the two latter being present in an amount at least sufficient to enhance the load-carrying capacity of the composition, e.g. 0.1 to 2% wt. and 0.005 to 1% wt. respectively.  Lubricating oils specified are mineral and synthetic oils having viscosities from 50 SUS/100 DEG F. to 250 SUS/210 DEG F.  The preferred synthetic oils consist of carbon, hydrogen and oxygen with or without silicon, e.g. polyalkylene glycols; polymeric alkylene oxides; polycarbonates; formals and polyformals; polyglycidyl and other ethers; polymethyl, polyethyl and polyphenyl siloxanes; esters, e.g. mono- and di-esters, which may be derived from C8-C24 monocarboxylic or C2-C12 dicar boxylic acids and alcohols, glycols, ether glycols or glycerol.  There are many examples of such esters, including bis(1H, 1H, 7H-dodecofluoroheptyl)-3-methyl glutarate.  The titanium compounds may be prepared as described in U.S.A. Specification 2,643,262 from an alkyl, aryl, alkaryl, cycloalkyl, alkoxy or mixed tetratitanate and a (preferably 1,3-) glycol which may be halogen-substituted.  The reaction products may be in a monomeric or polymeric form.  Preferred dicarboxylic acids have 2 to 12 to 20 carbon atoms.  In some examples, the dicarboxylic acid is omitted or replaced by a monocarboxylic acid or a half-ester of a dicarboxylic acid.  Optional ingredients present in some examples are phenothiazine, tricresyl phosphate, lithium stearate (to give a mineral or synthetic oil-based grease), and a polyester thickener derived by reacting sebacic acid with polypropylene glycol 150 and subsequently neutralising the product with 2-ethylhexanol and propylene oxide.  Specification 866,054 also is referred to.

Patent GB-1096847-A (GB)
Title: A process for the production of primary aliphatic hydrocarbon halides
IPC: C07C17/25
Filed: 1965-03-26
Abstract: Internal aliphatic olefins are obtained by the selective dehydrohalogenation of halogenated aliphatic hydrocarbons containing an internal halogen substituent which are in admixture with terminally halogenated aliphatic hydrocarbons.  The reaction is accomplished by heating the mixture of halogenated hydrocarbons in the liquid phase in the presence of an organic salt of a metal of Group VIII of the Periodic Table as a catalyst to a temperature sufficient to effect the desired selective dehydrohalogenation. The olefins may be subsequently hydrogenated to give alkanes.ALSO:Primary aliphatic hydrocarbon halides are produced from an organic halide system comprising a halogenated aliphatic hydrocarbon or a mixture of halogenated aliphatic hydrocarbons in which system there is at least one terminal halogen substitutent and at least one internal dehydrohalogenatable halogen substituent, said substituents being in the same or different hydrocarbons and each substituent being Cl, Br or I, by heating said system in the liquid phase in the presence of an organic salt of a metal of Group VIII of the Periodic Table as a catalyst to a temperature sufficient to effect the selective dehydrohalogenation of the internal halogen substituents but insufficient to effect the dehydrohalogenation of the terminal halogen substituents of said halogenated hydrocarbon or hydrocarbons. The initial mixture may be obtained by halogenation of a hydrocarbon and the olefinic products may be hydrogenated prior to separation from the primary halides.

Abstract: 757,444. Discharge apparatus; velocitymodulated tubes. TELEFONAKTIEBOLAGET L. M. ERICSSON. May 5,1954 [May 5, 1953], No. 13110/54. Class 39 (1). The gun unit of a reflex klystron or other discharge tube is aligned and centred by means of a disc-shaped metal electrode 3 sealed through the glass tube envelope 1, one gun electrode, as shown, gun anode 9, being provided with a conical portion matching a conical central portion 5 of the electrode 3, the gun electrode having the conical portion and the disc being soldered together. In assembly the gun unit comprising cathode 6, focusing electrode 8 with grid 16, and anode 9 carrying resonator grid 12 is inserted into envelope 1, having discs 2, 3 and reflector 4 sealed thereto, until collars 14, 15 and cones 9, 5 abut after which collars 14, 15 are soldered together. Before soldering the correct spacing between grids 12, 13 (and hence the correct resonant frequency) is obtained by first measuring the resonant frequency, then removing the gun unit and inserting an adjusting tool through a hole in disc 3 to deform either of the discs 2, 3 and so to adjust the gap width to the correct value, after which the gun is reinserted for the above soldering to be effected. The gun elements are supported and spaced by ceramic disc 7. The voltage to anode 9 is preferably supplied via the cavity resonator rather than by leads through tube base 10. The tube is completed by sealing glass base 10 to glass bulb 1.

Filed: 1938-05-04
Abstract: 514,394. Multiplex systems. BEATTY, W.A. May 4, 1938, No. 13260: [Class 40 (iv)] [Also in Group XL] In a multiplex system of the distributer type, each channel period is followed by a marking period during which a marking signal of a fixed duration peculiar to its position in the complete cycle is transmitted. 'For example, for transmitting five-unit printing telegraphy signals, each character of each channel is made up of the same five basic units, distinguished by differing tone frequencies, which modulate the carrier or by different steps of frequency modulation of the carrier, and the marking signal is distinguished by a sixth tone frequency or frequency-modulation, the channels being distinguished by the duration of the marking signal following each. The duration of each character element may be inversely proportional to its tone frequency. The marking signals may be separated by means described in Specifications 455,375 and 491,728, [both in Group XL]. Specification 443,896, [Group XL], also is referred to.

In an automatic photo-electric exposure setting device wherein an electric motor 8 which effects the setting movement is drivable in both directions of rotation in dependence on the deflection of the galvanometer pointer 14 of a photoelectric exposure meter, a pointer-sensing lever 3 spring urged to follow the pointer is coupled to a rotatable contact disc 5 having electrically separate contact paths connected to opposite poles of a D.C. source and engaged by sliding contacts 6 connected to the motor. Preferably in the rest position the sensing lever 3 is held clear of the pointer 14 in the rest position by a trigger 2. As shown the trigger 2 is in its final depressed position and has successively allowed the galvanometer pointer sensing lever 3 to engage the lever and closed the switch 21 in the circuit to the motor 8 via the contact surfaces on the disc 5 and the sliding contacts 6 secured to the wheel 10 driven by the motor and loosely mounted on the disc shaft 18 so that the shaft 20 is rotated to set the exposure factors in accordance with the photoelectric exposure meter response. When the trigger is released it first opens the motor circuit and then lifts the sensing lever 3 clear of the meter needle.
