Title: Improvements in or relating to fuel injectors for internal combustion engines
IPC: F02M67/10
Filed: 1924-05-20
Abstract: 223,514. Swan, Hunter, & W. Richardson, Ltd., Rowntree, F., and Belyavin, P. May 20, 1924. Cylinders receiving liquid fuel.-Fuel is supplied through a passage h in a hollow central plug H to the cup-like receptacle g<2>, Fig. 2, of a fuel injector, and, on the opening of a mechanically-operated air valve in the injection air supply piping, is blown into the cylinder through orifices j<1> in a nozzle J, by air admitted through an annular space g surrounding the plug H. Orifices h<5> admit air from the passage g to the upper part of the pochet g<2> to assist the pulverization of the fuel. A member h<1> which projects downwardly into the pocket g<2> may be adjusted relatively to the body of the injector so that the resistance to the flow of air and fuel through the injector may be varied. According to a modified construction, Fig. 4, which is applied to the bottom cylinder covers of double-acting engines, the spraying orifice is normally closed by a valve K opened automatically on the admission of spraying air to the annular passage g. Fuel is delivered to the annular pocket m, whence it is blown by the injection air through orifices l and past the, valve K into the cylinder. Orifices l<1> permit the entry of air into the passage surrounding the valve stem for the purpose of breaking up the fuel passing to the cylinder. The hollow member M may be adjusted in a similar manner to, and for the same purpose as, the member h<1> shown in Fig. 2. A modified form of valveless injector for use in the lower cylinder cover of a double-acting engine is also described. Several fuel injectors may be arranged in the cylinder head around a central starting valve or piston rod stuffing-box; in these cases a valve controlling the injection air is common to all the injectors. and the pipes leading to the valve have the same air resistance.

Title: Improvements in or relating to the moulding of thermosetting materials
IPC: B29C45/72
Filed: 1944-06-29
Abstract: 577,373. Injection-moulding thermosetting material. GOLDHARD, F. K., and PRENN, D. D. June 29, 1944, No. 12420. [Class 87 (ii)] The material is preheated throughout its mass before the injection operation to a temperature near the softening point but below the polymerization point, is maintained constantly below such polymerization point up to the time of leaving the injection feed passage, and is then heated above the polymerization point as it passes from the passage to enter the mould cavities. The apparatus shown comprises an injection cylinder 1, in which a passage 3 connects with a heating chamber 4 provided with electrodes 5, 6 for dielectric high-frequency heating. The cylinder 1 is maintained at a constant temperature by heating elements 9, thermostatically controlled. The injection nozzle 11, the temperature of which is similarly controlled, is cooled, especially during and after the injection operation, by liquid circulating in a space 12. With this arrangement, the plastic material, preheated throughout to a temperature near the softening point, is maintained below the polymerization temperature whilst in the injection cylinder and nozzle. As it passes through the sprue 13, which is heated electrically or otherwise by a device 14, or when it reaches the mould 18, the material is heated above the polymerization point. All or most of the heat required for polymerization may be imparted by the sprue channel, and a slight excess of heat may be applied in the sprue, during the injection stroke only, the excess being provided to replace heat losses in the mould.
Patent GB-580333-A (GB)
Title: Improvements in or relating to method of making adhesive compositions
IPC: C09J161/06
Filed: 1944-06-30
Abstract: An adhesive is prepared by condensing a phenol, preferably a polyhydric phenol, and furfural to form a fusible soluble partial condensate, dissolving the same in a volatile organic solvent, further condensing it in the presence of an acidic condensation catalyst to a point short of that to which the condensate becomes infusible, and adding to the solution thus obtained a solution in a volatile organic solvent of a vulcanizable natural or synthetic rubber.  Preferably the partial condensate is prepared by heating substantially equal proportions of a phenol and furfural to a temperature of about 80 to 110 DEG  C. for about 1 to 6 hours. Alternatively an excess of one reagent may be employed or an alkaline condensation catalyst may be present.  The further condensation is preferably carried out below about 40 DEG  C. and the reaction mixture may be cooled.  The solvent for the partial condensate may also be a solvent for the rubbery material, but the solvent for the rubbery material is preferably not a solvent for the phenol-furfural condensate.  The two solvents should, however, be miscible.  The adhesive may also comprise pigments, fillers, softeners, vulcanizing agents, vulcanization accelerators, and condensation and polymerization inhibitors, for example aliphatic mercaptans and phenylhydrazine.  The adhesive may be used for securing natural or synthetic rubbers to metal, plastics, concrete and wood.  Materials specified are: phenols: phenol, cresols, xylenol, resorcinol, naphthol, pyrogallol, phloroglucinol, hydroquinone; solvents for the partial condensates: ketones, e.g. methyl ethyl ketone or cyclohexanone; esters, e.g. butyl butyl acetate, butyl propionate, and cyclohexyl acetate ethylene dichloride; catalyst: amine hydrochlorides, e.g. hydroxylamine hydrochloride, a mineral acid or a metal chloride; natural rubber, e.g. heven or guayule; synthetic rubbers; polymers of aliphatic open-chain conjugated diemes, e.g. butadiene, di-methyl butadiene, piperylene, isoprene, methyl pentadiene, chloroprene or their copolymers with each other or with polymerisable compounds containing a single olefinic double bond, e.g. acrylonitrile, acrylic and substituted acrylic ester such as methyl acrylate and methyl methacrylate, styrene and its substitution products, vinyl ketones, vinylidene chloride, isobutylene.  In an example equal parts by weight of resorcinol and furfural are heated in the range 85 to 110 DEG  C. for about 4 hours, cooled to below 80 DEG  C. and dissolved in methyl ethyl ketone.  The solution is further condensed at 30 DEG  C. in the presence of hydroxylamine hydrochloride and there is added a solution in ethylene dichloride of the copolymer of butadiene and acrylonitrile.

Title: Electromagnetic bearing means
IPC: H02K7/09
Filed: 1973-03-16
Abstract: 1424071 Automatic control of position PADANA AG 16 March 1973 [20 March 1972] 12710/73 Heading G3R [Also in Division F2] A rotor 12 is supported with respect to a stator 13 by an axially magnetized annular carrier magnet 14, which holds the rotor 12 stable in the axial direction, and by two bearing arrangements 16 which maintain the rotor's stability in the radial direction. Each arrangement 16 comprises an annular permanent magnet 28 surrounding a closed ferromagnetic core 16 carrying a spirally wound or toroidal winding 20 which includes, or acts as, a plurality of separate coils. The magnetic fields produced by the winding 20 are superposed on the field produced by the magnet 28 in such a way that the latter field is weakened in one zone and strengthened in another Fig. 2, (not shown), resulting in radial forces on the shaft 12, these forces being automatically controlled to maintain the rotor stable in the radial direction. This control is effected by correctively varying the outputs from respective controllers 17, which energize the coils constituting the winding 20, in response to displacements of the shaft 12 as detected by sensors 18. The magnet 28 may comprise a maleable strip of permanent magnet material coiled around the core and its winding Fig. 8, (not shown); other configurations of core and magnet are described with reference to Figs. 4 to 7 and 9 (not shown). In another modification, the bearing arrangement is mounted on the stator and is received in a recess in the end of the shaft 12 Figs. 10 and 12, (not shown). The magnet 28 may be dispensed with, the control forces on the shaft 12 then being developed by a suitable asymmetrical arrangement of the winding on core 19, Fig. 11 (not shown).

Abstract: 1,139,566. Coated stretchable tape. STAUFFER CHEMICAL CO. 23 March, 1966, No. 12751/66. Heading B2E. Composite, elongatable tapes comprise continuous longitudinally disposed filaments of inelastic material, laterally spaced apart and shortened in the longitudinal direction by lateral contortions rendering the filaments longitudinally elongatable and elastomeric coating material completely embedding the filaments and defining the outer transverse cross-sectional configuration of the tape, the opposite longitudinal margins constituting the side edges of the tape being free of filaments, and one face of the tape having a marginal portion in a pressure-sensitive tacky condition and aportion in a non-tacky condition, and the opposite face of the tape having a similar but reversed tacky and non-tacky distribution of the tape area. The tape can be 'rolled without sticking. The filaments may be unwoven or woven e.g. in the form of parallel sinusoidal fibres, interlocked with breakable threads which are subsequently broken by stretching the tape. The filaments may be of glass fibres, copper wire or other electrical conducting metal or alloy in wire form, or polyethylene terephthalate. The elastomeric material may be an electrically insulating silicone elastomer, rubber or neoprene.- The margins of the tape may be bevelled, or have other shapes and configurations. When the filaments are of electrical conducting metal, the tapes are utilised as a stretchable electrical resistance element which may be wound and stretched about an oven part having acurved contour to form a heating element or the individual filaments may be utilised to connect parts of electrical circuits, the stretchability of the tape permitting use of such a connector in places where a stiff connector element cannot be used.
Patent GB-738207-A (GB)
Title: Improvements in or relating to morphine derivatives
Filed: 1953-05-07
Abstract: The invention comprises compounds having the general formula <FORM:0738207/IV (b)/1> wherein R is an alkyl radical containing not more than 5 carbon atoms and R1 is hydrogen or an alkanoyl radical containing not more than 6 carbon atoms and acid addition salts of such compounds.  It also comprises a process of producing a 6-alkyl-D 6-desoxymorphine by reacting a 6-alkyl-dihydromorphine with thionyl chloride, and the reaction of the product with an alkanoic acid anhydride to produce the corresponding 3 - alkanoyl - 6 - alkyl - D 6 - desoxymorphine.  The reaction with the thionyl chloride is preferably effected by heating the reactants under reflux and in a liquid medium of boiling-point within 50-90 DEG  C., such as a chlorinated solvent, e.g. tetrachlorethane, carbon tetrachloride or chloroform.  An excess of at least 50 per cent of thionyl chloride is preferred.  The acylation of the product is ordinarily conducted in the presence of a base.  Conversion into salts is effected in anhydrous media, e.g. ethanol, methanol or propanol.  In examples: (1) 6-methyldihydromorphine is refluxed in chloroform with thionyl chloride to give, after extraction of the neutralized mixture, 6-methyl-D 6-desoxymorphine, samples of which were converted to the hydrochloride and hydrobromide, and purified by sublimation, respectively; (2) 6-ethyl-D 6-desoxymorphine is prepared similarly to (1) from 6-ethyldihydromorphine; (3) 6-methyl-D 6-desoxymorphine is reacted with acetic anhydride to give 3-acetyl-6-methyl-D 6-desoxymorphine, which is converted to its hydrochloride.  Also referred to are a number of other compounds of the above formula, such as 6-propyl- and 6-butyl-desoxymorphines, 3-acetyl- and 3-propionyl-6-alkyldesoxymorphines, and the hydrochlorides, hydrobromides and sulphates of such derivatives.  The 6-alkyl-dihydromorphine derivatives used as starting materials are obtained by reacting dihydromorphine with an ethereal solution of an alkyl lithium to give, for example, 6-methyl-, 6-ethyl-, 6-propyl- and 6-butyl-dihydromorphines.

In further modifications the members are connected by three wheels and the pedal is connected to the spindle 2.
Patent GB-426843-A (GB)
Title: A process for the manufacture of alkenes and derivatives thereof
Filed: 1934-04-30
Abstract: Olefines containing at least 5 carbon atoms are obtained individually by fractional distillation of cracking products of paraffin wax or mixtures containing more than 20 per cent of paraffin wax.  The cracking is preferably effected in the vapour phase or first in the liquid and then in the vapour phase, at temperatures not exceeding about 600 DEG  C.  A distillate of cracked white paraffin wax yields fractions consisting mainly of hexene, heptene, octene and nonene respectively, which may be used for the production of the corresponding alcohols, ethers, esters, chlorides, &c.  In an example, to the nonene fraction obtained as above described is added drop by drop 90,3 per cent sulphuric acid at 0--5 DEG  C. while stirring, and stirring is continued at 8--10 DEG  C.  The mixture is then diluted to 15 per cent and steam is blown through; the upper layer of the distillate is treated with 50 per cent alcohol to separate the nonyl alcohol from the polymer.  The Specification as open to inspection under Sect. 91 contains another example in which the heptene fraction of the distillate is stirred with water and a little sulphuric acid, and tertiary butyl hypochlorite is added to produce the chlorhydrin; the upper layer is then added to 30 per cent caustic soda while stirring at 116--118 DEG  C., yielding a distillate containing a -heptene oxide, tertiary butyl alcohol and water, the heptene oxide forming an upper layer.  This subject-matter does not appear in the Specification as accepted.
