Title: Rotary-piston internal combustion engines
IPC: F01C21/04
Filed: 1974-05-31
Abstract: 1421882 Preventing lubricant/coolant leakage in rotary IC engines TOYOTA JIDOSHA KOGYO KK 31 May 1974 [6 June 1973] 24322/74 Heading F1F In a rotary internal combustion engine of the type having a rotor 2 disposed for planetary movement in a housing 1, leakage of lubricant/coolant in chambers 5,6 in housing side wall 4,4' and rotor 2 respectively is prevented by seals 22, 24, 27 between respective housing and rotor openings 10, 14 9 and parts rotating with the output shaft 11, 11', the openings 9, 10 being tapered inwardly of the rotor 2 and the opening 14 being tapered outwardly of the side housing portion 4. Shaft 11, 11' has an integral eccentric portion 12 rotatably mounted in a hub 7 of rotor 2. Hub 7 has an internal gear 8 which meshes with a gear on a sleeve 17, which sleeve is stationarily held in an opening 15 in an outer side wall portion 4'. A clearance 30 is formed between the external surface of a gear sleeve 17 and a bore in an oil "slinger" 20 which is integral with eccentric portion 12 and is located in the opening 10. Seal 22 acts between opening 10 and a groove 21 in slinger 20, seal 24 acts between opening 14 and a groove 23 in a reduced diameter projection 19 of slinger 20, and seal 27 acts between opening 9 and a groove 26 in a portion 25 fixed to the-eccentric portion 22 and coaxial therewith. Thus fluid is prevented from leaking from chamber 6 to the working chambers by seals 22, 27, and fluid passing via clearance 30 to chamber 5 is prevented from leaking into the working chambers by seal 24.

Abstract: 695,081. Electric incandescent lamps. EGYESULT IZZOLAMPA ES VILLAMOSSAGI, R. T. Oct. 19, 1951 [April 26, 1951], No. 24448/51. Class 39(ii) Electric incandescent lamps are provided with an internal coloured coating comprising at least one inorganic colouring substance capable of acting as a getter, the inorganic colouring substance being in the form of granules the size of which is of the order of 0.1 to 10 microns. Preferable examples of such substances are:-titanium white. iron oxide black, cadmium selenide and the like. More. than one colouring substance may be employed, at least one of which acts also as a getter material, a preferable example comprising silicic acid together with a colouring material acting as a getter. In an example the colouring material ground to granules, preferably of about 0.3-3 microns in size, is mixed with collodion, or a synthetic resin. or collodion and one or more synthetic resins such as a polyvinyl or silicone resin in a solvent. Thus, titanium white is ground to granules of 2-2.5 microns and dispersed in collodion dissolved in butyl acetate. The dispersion is poured into a lamp bulb and, spread over the inner surface, e.g. by shaking the bulb or stirring the liquid to produce a uniform coating. After pouring out the excess liquid the bulb is heated to a temperature of about 150-160‹C to evaporate the butyl acetate, and finally heated to about 450‹C to decompose and burn the collodion. In a further example cadmium selenide is used as the colouring matter and getter material, and a mixture of collodion and a silicone resin as a binding agent. After heating the I coating to remove the solvent it is heated to 480‹C to convert the main part of the silicone resin to silica. In a further embodiment of the invention the binding agent consists only of silicone resin dissolved, for example, in toluene. One or more additional getters, e.g. phosphorus or the like, may be arranged in known manner inside the bulb. Krypton or xenon, or a mixture of those two gases, may be used as the filling gas.

Title: Packaging technique for fabrication of very small semiconductor devices

Filed: 1959-07-21
Abstract: 925,085. Semi-conductor devices. PACIFIC SEMICONDUCTORS Inc. July 21, 1959 [July 21, 1958], No. 25032/59. Class 37. A semi-conductor device having a PN junction is provided with a polysiloxane film which seals it from the atmosphere. As shown, Fig. 4, a PN junction 10 has a gold-plated " Kovar " (Registered Trade Mark) or molybdenum tab alloyed to the P layer and a similar tab 19 alloyed to the N layer. The tab alloyed to the Pa layer may be aluminium doped and that alloyed to the gold layer may be phosphorus doped. A gold coated copper electrode 23 is welded to the upper tab and gold coated metal ribbon which may be welded to a heavier electrode 30 is bonded to the lower. A polysiloxane film 32 greater than 1 micron in thickness is then deposited around and surrounding the crystal. To produce the film the device with its electrodes is immersed in an etch containing hydrofluoric and nitric acid and is then immersed in a quench solution comprising primarily an organic liquid which has in its chemical structure a reactive hydroxyl group; a 95% ethanol solution is preferred. This process forms ester groups which are molecularly bonded with the silicon surface. The ester is then reacted with a mixture of organo silicon compound in which a trifunctional monomer predominates. The reactive group X of such monomers having the formula RSX3 can be the hydroxyl group but trihydroxy compounds rapidly auto-polymerize. A tri-alkoxy compound such as ethyl tri-ethoxy silane is preferred as a starting material which is then hydrolised to the hydroxyl compound just prior to use. The reactive groups may also be mercapto, amino or halide groups. The Specification states the addition of di- and monofunctional organo-silanes offer certain advantages. An embodiment is described in which a transistor is mounted in a polysiloxane film.

Title: Wetting-out treatment of fibrous materials
IPC: D06M13/224
Filed: 1944-12-15
Abstract: A process of wetting out fibrous material comprises first treating the material with a mono-oxy compound, or mixture of such compounds, wherein the oxygen atom is directly linked to a single carbon atom of a hydrocarbon radical of eight to eleven carbon atoms or, in the case of a mixture of compounds, having an average of eight to eleven carbon atoms, and then contacting the fibrous material with an aqueous solution of an anion active detergent or wetting agent.  The mono-oxy compound is preferably a primary or secondary alcohol, but may be an aldehyde or ketone.  Where mixtures of mono-oxy compounds are used, it is not essential that the individual components have eight to eleven carbon atoms in the molecule provided that the weighted average of such materials falls in this range.  The detergent may be a water-soluble salt of an organic compound in which a hydrocarbon radical is linked with a carbonyl, sulphonate or sulphate group through an ester, amide or aryl linkage, e.g. salts of sulphonated or sulphated primary or secondary alcohols; salts of isethionic or taurine condensation products with fatty acids; salts of alkyl or aryl sulphonates; and fatty acid, naphthenic or rosin acid soaps.  The detergent is preferably the sodium salt of a sulphated aliphatic alcohol containing eight to eighteen carbon atoms in the molecule.  The mono-oxy compound may be applied as a vapour, spray or mist or by immersion of the material in the liquid-treating agent or non-aqueous solution thereof.  The Provisional Specification also includes the use of amines corresponding to the above-mentioned alcohols as pretreatment compounds.
