Class 79(5) In a worm and nut steering mechanism a nut 13 (Fig. 1) which engages a threaded steering shaft 11 by means of recirculatory balls has mounted thereon a pin 14 carrying two ball or roller bearings 18, 19, and a forked arm 20 on a steering arm shaft 21 has two contact surfaces 22, 23 disposed on either side of the pin 14, only one surface 22, 23 being in contact with each bearing 18, 19 so that during steering movements the bearing may run freely but without backlash. The surfaces 22, 23 and the contacting surfaces of the bearings 18, 19 are conical with an inclination of 10-18 degrees which approximates to the angle of friction between the surfaces. A spring 40 is interposed between an adjustable nut 27 and the bearing 18 to press the contacting surfaces firmly together and to compensate for wear. Alternatively the conical surfaces may have their apices directed away from one another with a spring located between the bearings and preferably with a forked arm of divided construction. A roller 15 on the pin 14 engages a guideway 16 which may be parallel to the steering shaft 11, inclined relative thereto or curved to provide desired steering characteristics. In another construction (Figs. 2, 4) the contact surfaces of the forked arm 20 and of two double-row ball bearings 28, 29 each with two separate inner races are inclined in the same direction and the surfaces are pressed firmly together by a spring 33 provided with an adjustable abutment 37 and acting on the steering-arm shaft 21 through a pot 36.

[Also in Group VIII] In a glass fibre mat providing a low density (of the order of less than thirt) pounds per cubic foot) of glass. fibrous material and having a sufficient coherence and integrity to be self sustaining when handled, the glass fibrous material is in the form of short cut staplelength bundles each containing many individual glass filaments extending generally parallel to the plane of the sheet but randomly oriented in the plane, the bundles being united in sheet form without adhesive bonds solely by engagement with glass fibres extending in the sheet in the direction of its least dimension. In the apparatus shown for forming such a mat a rope 4 of glass filaments is fed to a cutting device 2 from which short bundles of fibres drop into a hopper feeder 10. From here they are fed with the aid of an air stream and a foraminous belt 22 to the belt 28 when they form a bat 24. This bat then passes under a needling device 34 so that some fibres are forced transversely of the bat. If desired additional facing webs 48 of adhesively bonded glass filaments may be fed with the bat 24 to the needling device.

Title: Improvements in or relating to anti-corrosion oils
IPC: C09D5/08
Filed: 1948-03-12
Abstract: An anti-corrosion oil comprises a major proportion of one or more hydrocarbon oils having a boiling range between 50 DEG  and 370 DEG C. and minor proportions of a petroleum residue, as specified below, a protective agent, an alkali metal salt of an oil-soluble naphthasulphonic acid and an aliphatic alcohol containing not more than 8 carbon atoms in the molecule.  The hydrocarbon oil may be petroleum naphtha, white spirit, kerosine, or benzene, toluene or xylene or solvent naphtha.  The petroleum residue is obtained from the redistillation of a lubricating oil distillate containing alkaline earth metal naphthenates.  The protective agent is a fatty or oily material of animal, vegetable or mineral origin, and may be woolfat, preferably lanolin, petrolatum, heavy hydrocarbon oils such as the residues from the cracking of petroleum wax, asphaltic bitumens or blown semi-drying oils such as blown rapeseed oil; synthetic agents such as glyceryl monooleate may also be used.  The aliphatic alcohol used is preferably diacetone alcohol, but ethyl, isopropyl and butyl alcohols are also mentioned.  A plasticizer such as zinc naphthenate and an antioxidant such as phenyl-b -naphthylamine may also be added.  A composition containing 55-70 per cent hydrocarbon oils, 15-35 per cent petroleum residue, 2-15 per cent of protective agent, 1-10 per cent naphthasulphonate and 1-10 per cent aliphatic alcohol is preferred.  In one example, the residue remaining after redistillation of a lime-neutralized lubricating oil distillate containing naphthenic acids is dissolved in white spirit, the solution filtered and the filtrate blended with lanolin, the sodium salt of an oil-soluble naphthasulphonic acid and zinc naphthenate; diacetone alcohol, spirit of boiling range 100-160 DEG C. and more white spirit are then added.

Abstract: 1526512 Producing selective excitation by electromagnetic radiation EXXON RESEARCH & ENG CO 27 Feb 1976 [23 April 1975] 07828/76 Heading G6P In a process of isotope separation involving isotopically selective excitation (by irradiation with electromagnetic radiation) under conditions in which vibrational excitation by multiple photon absorption occurs, thermal electrons are attached to the excited species to form negative ions which decompose to form ion fragments which can be separated out. The mixture to be separated comprises a molecular gas of a compound whose general formula is MF 6  where M is one of U, S, W, Se, Te, Mo, Re and Tc. Helium may be added as a buffer gas. The process involves three stages, namely :- (1) Irradiation by infrared (e.g. pulsed CO 2 ) laser for less than 10<SP>-3</SP> sec. Such that at least 0À1% of the molecules of one isotope are excited to a vibrational energy content of 4v3 by multiphoton absorption.  (2) Thermal electrons (e.g. generated by an electron gun) are contacted with the mixture and become attached to both excited and unexcited molecules to form negative ions MF 6 - (unexcited) and *MF 6 - (excited). The ratio of thermal electrons to total MF 6  molecules is at least 0À1. Contact occurs for less than 10<SP>-3</SP> sec. in order to minimize thermal dilution. (3) The MF 6 - ions do not dissociate, but the *MF 6 - do so rapidly (i.e. *MF 6 <SP>-</SP>#MF 5 <SP>-</SP>+F). If a chemical reaction is used to separate the fractions, MF 6  will remain in the gaseous phase while MF 5  will precipitate. Electromagnetic separation can be used.
