Process to separate propene from gaseous fluid catalytic cracking products by performing the following steps: a) separating a feed mixture comprising the gaseous products, propene and other saturated and unsaturated hydrocarbons obtained in a fluid catalytic cracking process into a hydrocarbon-rich liquid fraction and a hydrogen containing gaseous fraction, b) separating the hydrogen containing gaseous fraction into a hydrogen-rich gaseous fraction and a hydrocarbon-rich gaseous fraction by mean...

An exemplary data processing device includes a clock recovery system for locking a clock frequency to time stamps (PCR) of an incoming data stream, e.g. MPEG. The exemplary device uses a free running clock (20) that generates a reference frequency (FREF) from which a desired locked clock frequency is synthesized (25,35) under control of a processing unit (24,34) that compares (241,341) the locked clock frequency to the time stamps (PCR). MPEG audio and video processing clock frequencies are synt...

A gas recovery system comprising a source of gas having a preselected concentration of a desired component (9), at least one application (1) that adds impurities to said gas, and at least one an adsorption system (6) that purifies said gas to produce a purified gas for re-use in application (1), wherein said at least one adsorption system includes at least one adsorbent bed (A) having at least three layers of adsorbents. A recovery process is also disclosed.

A recovery device particularly useful in confined space and remote rescues. The recovery device includes a base plate, a winch coupled to the base plate, and an anchoring plate coupled to the base plate to detachably couple the base plate to an object that will support the recovery. A cord is attached to the winch to raise or lower the load to or from the recovery device or object. A guide roller assembly is coupled to the base plate to guide the cord and reduce the amount of friction on the cor...

The invention herein provides a method for recovering a polypeptide comprising exposing a composition comprising a polypeptide to a reagent which binds to, or modifies, the polypeptide, wherein the reagent is immobilized on a solid phase; and then passing the composition through a filter bearing a charge which is opposite to the charge of the reagent in the composition, so as to remove leached reagent from the composition.

A process for the recovery of carotenes and the production of carotene concentrate from natural oils and fats. The carotene-containing natural oils and fats is subjected to alcoholic esterification to form a mixture of fatty acid alkyl esters, carotenes, tocopherols and tocotrienols. The alkyl esters mixture is subjected to vacuum distillation at a pressure of less than 60 mTorr and a temperature of less than 180.degree. C. to form a carotene-rich concentrate. The carotenes in the carotene-rich ...

A medical instrument, or collection instrument, for collecting foreign material, such as calculuses and clips that have fallen in the abdominal cavity, is disclosed. The collection instrument includes a tube (1) that is hollow in the longitudinal direction and a collection bag (2) arranged at one end of the tube (1). The collection bag includes a barrier member having a fluid passage characteristic.

The invention herein provides a method for recovering a polypeptide comprising exposing a composition comprising a polypeptide to a reagent which binds to, or modifies, the polypeptide, wherein the reagent is immobilized on a solid phase; and then passing the composition through a filter bearing a charge which is opposite to the charge of the reagent in the composition, so as to remove leached reagent from the composition.

Encoded data is decoded by a receiver for an analogue input signal that is converted into a digital signal. A detector produces a sequence of data representative of the analogue signal, a decoder for the sequence of data outputs data indicating that a sequence includes an error. An event detector detects an event which substantially alters or destroys the analogue input signal. The decoder outputs data corresponding to the or each sequence resulting from the altered or destroyed analogue input s...

A waste heat recovery system incorporates a contactor for counter current direct heat exchange between a non-condensible gas and a liquid, typically hot water. The water is from a heat source available at the site such as a solar source, a geothermal source, an industrial plant or the like. Hot mainly saturated gas exits from the contactor and drives a motor, typically a turbine. The turbine drive a work consuming device, normally an electric generator. A condenser/separator downstream from the ...
