IPC: C10G/
Filed: 1976-01-15
Granted: 1981-11-30
Abstract: Combined single reactor process is for (A) catalytic conversion (e.g. trans-alkylation) of 7-12C alkyl aromatic hydrocarbons, or alternatively (B) thermal hydro-dealkylation of the same hydrocarbons, on an acid heterogeneous catalyst. (A) is carried out at 288-538 degrees, and (B) at 427-704 degrees C with addn. to the charge of an agent for reversible poisoning of the acid sites on the catalyst. The catalyst is a crystalline Al silicate zeolite material or thermal decomposition product thereof. The poisoning agent is a basic cpd. contg. S, N or O atoms. Reactor is used for disproportionation of toluene to benzene, isomerisation etc. A single reactor system can be used for both processes the change-over being effected by stopping or starting the flow of poisoning agent and charging the operating conditions.

Title: Annular flange for tube has body of epoxy!-bonded glass fibre
Inventor: MEDNEY JONAS
IPC: F16L/
Filed: 1984-12-21
Granted: 1987-09-16
Abstract: The component comprising at least an annular flange (10) with central opening (12) and a symmetry axis (14) consists of a body formed of fibres (20) held together by a bonding agent. The novelty is that each fibre extends in a mean direction of which the component vector normal to the axis is greater than that parallel to the axis. The fibres are pref. glass fibres whilst the bonding agent is epoxy-resin (or possibly polyester, vinyl ester or similar). The mean direction of each fibre is pref. generally parallel to a tangent to the opening but subtends a greater angle (e.g. 120 deg., pref. 90-180 deg.) than the chord formed by that tangent (i.e. the fibres are outwardly convexly curved). The opening and the outer perimeter (16,24) pref. have circular cross-section whilst the outer surface (24) is outwardly concave (bell-shaped) and the flange face is plane and normal to the axis and may be provided with projecting concentric ribs.

Title: Safety brake mechanism for chain saw - has movement of guard member deflecting latch finger which allows column spring to apply brake
IPC: B23D/
Filed: 1978-08-08
Granted: 1989-04-27
Abstract: The guard member is mounted on the chain saw for swinging movement between an actuate position and a reset position. The guard member occupies a normal position between the actuate and reset positions. A brake band is integral with a bowed column spring which applies the braking force to arrest movement of the cutting chain. A latching mechanism includes an arm with a latch pin engaged by a yieldable latch finger, the latch finger being integral with the bowed column spring. The guard member deflects the latch finger in response to movement of the guard to its actuate position, this action allows the column spring to apply the brake. The guard member is moved to its actuate position in response to a sudden movement of the chain saw, as in the case of 'kickback'.

When the Ca:P molar ratio is in the range 1À62-1À72 a translucent, isotropic, polycrystalline hydroxylapatite having an average crystalite size of 0À2-3 microns, a density of 3À1-3À14 g/cm<SP>3</SP>, substantially no pores and having cleavage along smooth curved planes is obtained. When the Ca:P ratio is in the range 1À44-1À60, preferably 1À46-1À57 a dense isotropic two-phase ceramic is obtained comprising 14-98% hydroxylapatite and 2-86% whitlockite, said ceramic having substantially no pores and having cleavage along smooth curved planes. The reactants are preferably Ca(NO 3 ) 2  and (NH 4 ) 2 HPO 4 . 0À4-0À6% of an organic binder, e.g. collagen, may be added to the precipitate to prevent cracking during drying. Porous forms of the ceramic may be made by including 5-25% by weight of organic binders such as powdered cellulose, starch, cotton or collagen to the precipitate. Fluoride ions may be introduced into the ceramic, e.g. by standing in 0À5-5% aqueous NaF for 12 hours-5 days.

Title: Spark plug with insulation covered electrode points - insulation reduces chemical and electrical erosion
IPC: F02P/
Filed: 1974-12-18
Granted: 1978-09-20
Abstract: The spark plug has electrode points covered by non-conducting material so that it is the space between them which ignites the fuel mixture. The points may produce several sparks in each ignition cycle. This solution will lessen the problem of electrical and chemical erosion which usually limits the life expectancy of conventional models of plugs and also calls for a more frequent cleaning of the points and regulation of their spacing, a sthe material covering the points is resistant to high temperatures. The central and earth electrodes may have a neutral electrode covered by a non-conducting material between them.

IPC: A23C9/00
Filed: 2014-02-07
Abstract: The present invention relates to the production of dairy products, in particular to the production of sour cream 38 percent fat from recombined milk. In the manufacture is used 10-45 percent of the natural skimmed milk, purified using the extremely small high-tech filters, to carry the process at low temperature in order to maintain undenatured proteins. Another component of the product - water, which is basis of chemical and microbiological processes of food, is also purified extremely by using the reverse osmosis method. By combining specially purified components can be obtained product having the desired properties. Advantage of this invention is that the skimmed milk has not been exposed higher than at 58 °C temperature and has preserved all milk constituents (undenatured proteins, vitamins, minerals, lactose), and combining with water and dry milk matter, allows to obtain high-quality milk product.
