Patent GB-574899-A (GB)
Title: Improvements in or relating to the synthetic production of the oestrogens stilboestrol and hexoestrol
Inventor: KHARASCH MORRIS SELIG
IPC: C07C39/215
Filed: 1943-01-13
Abstract: Synthetic oestrogens are made by hydrohalogenating a propenylphenyl alkyl ether in which the alkyl group contains from 1-4 carbon atoms, treating the resulting hydrohalide with an excess of either an alkali metal or alkaline earth metal amide in liquid ammonia and dealkylating the product.  The preferred starting material is anethole, the preferred hydrohalogenating agent is hydrogen bromide and the preferred amide is sodamide.  An alternative phase of the invention is to hydrogenate the reaction product obtained by the amide treatment above before applying the final dealkylation step. This results in a saturated final product.  The hydrogenation may be effected by hydrogen in the presence of a platinum black catalyst, Raney nickel, or palladium black on barium sulphate.  In examples: (1) anethole is treated in toluene solution with hydrogen bromide and the hydrobromide so produced is added to a solution of sodamide in liquid ammonia. The ammonia is removed and the product taken up in ethyl acetate to give p-p1-dimethoxy-3 : 4-diphenyl-hexane-1; (2) the compound prepared in example (1) is hydrogenated in the presence of platinum black to give hexoestrol dimethyl ether; (3) the ether obtained in example (2) is demethylated by treatment with caustic potash in ethylene glycol solution; (4) the compound prepared in example (1) is demethylated as in example (3).

Title: Process for the production of coke and gaseous unsaturated hydrocarbons
IPC: C10B55/00
Filed: 1956-01-11
Abstract: Coke and gaseous unsaturated hydrocarbons, particularly ethylene or acetylene, are produced from a heavy hydrocarbon charge by (1) heating to a temperature of 700-800 DEG  F. but below the cracking temperature and introducing into a flash zone from which a bottoms fraction boiling in the heavy fuel oil range is withdrawn; (2) heating such bottoms to 900-950 DEG  F. and introducing the heated bottoms, partly in the vapour phase, into a coking zone to crack the liquid mildly and form coke and additional vapours; (3) withdrawing vapours from the coking zone and introducing them into the flash zone of step (1) below the pre <PICT:0830968/IV (b)/1> heated charge whereby heavy constituents are condensed out; (4) withdrawing vapours, including gas, gasoline, gas oil and light ends from the charge, from the flash zone, mixing them with superheated steam and cracking them by contact with a thermally regenerated refractory mass at 1500-2200 DEG  F. for a period of time of a fraction of a second to several seconds to produce an effluent containing a high percentage of gaseous unsaturated hydrocarbons; and (5) quenching the effluent and separating unsaturated hydrocarbons as product and withdrawing coke from the coking zone as product.  Charge is heated in heater 11 and passed to flash tower 13 operated at 15-30 p.s.i.g. The bottoms are further heated and introduced into one or other of coking zones 17 and 17a operated at 20-35 p.s.i.g.  Coke is removed by lines 19 and 19a.  Vapours pass by line 21 to the flash tower from which overhead vapours pass to the furnace 23, usually one of a pair operating alternately and being alternately heated and used for cracking.  There the vapours are cracked at 1500-1800 DEG  F. and 1-2 atmospheres diluted with 0.5-2 times their weight of steam for 0.05-0.15 second to produce ethylene or 1800-2200 DEG  F. and 1 atmosphere with 3-6 times their weight of steam or 0.5 atmosphere and 2.5-5 times their weight of steam for 0.02-0.08 second to form acetylene.  The product vapours are partially quenched in the furnace and further in tower 31 then temporarily held in holder 35.  After compression the vapours are contacted in absorber 38 with a side stream from flash tower 13 to remove C5+ hydrocarbons and aromatics, the bottoms from the absorber being returned to the flash tower as a reflux.  The overhead is passed to acidic removal section 62, if desired acetylene is selectively hydrogenated at 64, and the vapours finally fractionated at 68.

Date Apr. 30, 1992.The invention relates to a process for the combined generation of electrical and mechanical energy from the oxidation of fuel. In particular a hydrogen-containing gas is generated by endothermic reaction of hydrocarbon compounds, in which a portion of the hydrogen-containing gas is burned for generating a combustion gas. An oxygen-containing gas is then compressed and introduced into the combustion stage, and the energy is generated by expanding the hot combustion gas in at least one gas turbine. Further, the expanded combustion gas is used for indirect heating of the endothermic reaction. According to the present invention, at least a part of the generated hydrogen-containing gas is to be guided as anode gas through a fuel cell system for generating electrical energy and the anode exhaust gas is used for generating the combustion gas.

Title: Package unit for photosensitive material with photographing function
Inventor: SHIBA KEISUKE
IPC: G03C3/00
Filed: 1989-01-06
Abstract: PURPOSE:To increase an image formation distance even at a narrow photographing part in a unit and to obtain a sharp image with no flare by reflecting incident light from a lens to a photosensitive material by at least one mirror. CONSTITUTION:This unit has a fixed-focus lens 63 which has 35 - 150mm, preferably, 75 - 135mm focal length shorter than that of a conventional single lens. Further, this unit is equipped with at least one mirror 35 or 36 which reflects the incident light from the image forming lens to the photosensitive material. Further, at least one light shielding frame 101 (including a light shielding piece) is positioned off the optical path of reflection by the mirror 35 or 36 so that the tip of the frame is close to the optical path. The surface of the light shielding frame 101 facing the mirror 35 or 36 is black and formed high without protruding into the optical path to prevent external light exceeding a field angle and light reflected by the light shielding frame 101 or light shielding piece from striking on the photosensitive surface of the photosensitive material. Consequently, image formation distance can be made long even at the narrow photographing part in the unit, and the sharp image having no flare is obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing an SOI substrate without affecting a variety of film width of a semiconductor substrate on a variety of the film width of an SOI layer and allowing an increase in uniformity of the film width of the SOI layer. SOLUTION: In a method of manufacturing an SOI substrate, first, a spot which is to become an element separation region on the surface of a semiconductor (silicon) substrate 1 is selectively etched.

Title: Object detector
Inventor: YONEMURA TAKAMOTO
IPC: G01S13/04
Filed: 1999-01-05
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle-to-vehicle distance detector capable of accurately controlling a detecting range of a sensor, such as radar. SOLUTION: To avoid a sensor error triggered by a guardrail placed on a curving road side, detecting ranges Sr, Sc, and Sl for detecting a vehicle running ahead are determined based on a radius of curvature of the road (turning radius of a vehicle). When calculating the radius of curvature of the road, transverse acceleration of the vehicle is considered in addition to turning angular velocity of a tire. Therefore, the detecting range of the sensor can be accurately controlled.
