Abstract: ABSTRACT    The invention provides corticoid-21-sulphopropionates and their salts, especially physiologically tolerable salts and pharmaceutical preparations containing them. They are distinguished in comparison with free 21-hydroxycorticoids by being readily soluble in water.  In comparison with sodium salts of corticoid-21-hemisul-phates, -phosphates and -sulphobenzoates, the corres-ponding 21-(3-sulphopropionate) compounds are split in the body rapidly into the active ingredient, the 21-hydroxycorticoids, and in comparison with sodium salts of corticoid-21-hemisuccinates and -aminoacylates they are more stable in aqueous solution.      Preferred compounds have the formula                     (II), in which     represents a single or double bond, X       represents hydrogen, chlorine, fluorine or methyl, Y       represents hydrogen, fluorine or chlorine, Z       represents oxo or .alpha.-hydrogen and .beta.-hydroxy, -U-V-   represents-CH2CH2,-CH=CH- or         and      represents     ,       or           wherein R1   represents hydrogen, hydroxy or (C1-C8)-acyloxy, R2   represents hydrogen or methyl, and R3 and R4 each represent (C1-C4)alkyl, and especially the salts thereof.

Title: Internal combustion engines integrated  with heat recuperators
Inventor: HAIMAN JOHN J CHESTERTON DRIVE
IPC: F02G5/00
Filed: 1980-03-14
Granted: 1981-12-22
Abstract: ABSTRACT More than 60 % of the heating value of the fuel consumed in the usual internal combustion engines is wasted past remedy. The present invention, which is applicable in combination with any type of internal combustion engine, is devised to reduce the heat losses and to improve the ef-ficiency of the thermodynamic cycles by making practicable an increase of the compression ratio, while suppressing knocking. Besides, a reduction in the emission of pollu-tants is achieved.        The invention embodies apparatus to generate super-heated steam, comprising a water preheater, a forced - cir-culation steam generator, a steam separator, a steam super-heater which forms the actual jacketed cooling system of the engine, and a feasibly complete thermal insulation sys-tem. Said apparatus is integrated with the internal combus-tion engine, its steam generating constituent parts being arranged in countercurrent to the flow of the combustion products generated by the engine's process.        The superheated pressure steam is utilized as mo-tive power for an injector-compressor serving to pre-com-press the combustion air for compression-ignition or other fuel injection engines, or to supercharge the air-fuel mix-ture in the case of carburetor engines. In all cases, the compressed gaseous intake, incorporating the injected su-perheated steam, enters the engine's working space with in-creased enthalpy. If superheated steam is produced in excess of the demand of the compressor, it will be fed directly into the working space with appropriate timing.        The invention offers the convenience of reducing the usual heat losses to the only heat being rejected with the cooled exhaust gases.

Abstract: Abstract A method for forming thin film patterns in the fabrication of integrated circuits utilizing a lift-off mask in an inverse vertical relationship with the desired metal film.  The method involves the preliminary blanket deposition of the metal in-point, followed by a coating of a patterned lift-off mask over which is blanket coated a dry-etch resistant material with subsequent removal of the lift-off mask, and dry etching of the exposed metal film.  In one embodiment the dry-etch mask can comprise a diverse metal layer when a dry-etch ambient is employed which is passive to the d;-verse metal.  In another embodiment, where dry etch ambients are employed which are corrosive to the diverse metal which is desired in the final structure, it can be covered with a blanket layer of any convenient dry-etch resistant material, such as magnesium oxide, prior to removal of the lift-off mask.  This method has effective appli-cation in the fabrication of Schottky barrier diodes, transistors, and other electronic compon-ents or discrete and integrated devices requiring high quality metal to semiconductor junctions or interfaces.

Abstract: ENHANCED OIL RECOVERY EMPLOYING BLEND OF CARBON DIOXIDE          INERT GAS AND INTERMEDIATE HYDROCARBONS                (PR 5210) (D#77,149-F) ABSTRACT OF THE DISCLOSURE Oil may be recovered from dipping reservoirs by a conditionally miscible oil recovery process in which a gaseous, carbon dioxide-containing fluid is injected up-dip to displace petroleum downward in a conditionally miscible, gravity-stabilized displacement process.  Carbon di-oxide-containing blending stock is mixed with an inert gas such as methane or nitrogen in order to reduce its density sufficiently to increase the critical velocity of the dis-placement process.  By increasing the critical velocity, the time required to deplete a reservoir is decreased signifi-cantly.  Sufficient intermediate hydrocarbons are added to the mixture of carbon dioxide and inert gas to insure that the mixture injected into the formation is conditionally miscible at formation temperature and pressure.

Abstract: ABSTRACT OF THE DISCLOSURE          An automatic telephone answering device employs a single magnetic tape and a single driving mechanism for driving the magnetic tape.  Whenever an incoming call is received, a control circuit of the device sets the driving mechanism into a playback mode to play to the calling party an outgoing message recorded at the beginning of a track on the single magnetic tape.  Then, if there have been no previously recorded incoming messages, the device records the calling party's in-coming message on the same track after detecting the end of the recorded outgoing message.  However, if any incoming messages have been recorded previously on the same track of the single magnetic tape, the tape is advanced at high speed to a point beyond the last of these previously recorded incom-ing messages.  Then, the present incoming message is recorded. As soon as the incoming call is terminated and the recording of the incoming message is ended, the device is set into a rewind mode.  When the beginning of the recorded outgoing message is detected, the driving mechanism is stopped, and the device is set into a standby mode to greet the next incoming call with the recorded outgoing message.  In a preferred embodiment, a microcomputer is used to control the operation of the device. Also, in a preferred embodiment, a low-frequency (30Hz) control signal is recorded with the outgoing message and with the in-coming messages, and the recorded messages are separated by silent regions free of any recorded control signal.

Abstract: ABSTRACT         In order to suppress triple transit ghost images in a T.V. receiver, a surface wave acoustic filter is provided in which either the input or output transducer system, or both, includes both primary and dummy transducers, the echoes from which cancel each other totally.  The dummy transducer is designed as a function not only of position along the acoustic beam path, but also as a function of the number of elemental transducers and their inter-digitated lengths; and the design also takes into account relevant electrical parameters including transducer admittances and any external or parasitic impedances under short circuit and open circuit conditions.  These factors are taken into account not only for the primary transducer, but also for the dummy transducer.  The result is a completely general phasor expression which establishes the design criteria for a dummy transducer to achieve echo phase opposition and amplitude equality, relative to a given primary transducer and a given external circuit under all frequency conditions.  The result is complete echo cancellation over the entire bandwidth of the filter.
