Patent number: 9580312Abstract: The invention relates to a continuous method for producing acetylenes and syngas by partially oxidizing hydrocarbons with oxygen. A first feed stream (1) containing one or more hydrocarbons and a second feed stream (2) containing oxygen are —mixed in a ratio of the mass flows of the second feed stream (2) to the first feed stream (1) corresponding to an oxygen number of less than or equal to 0.31, said streams being heated separately from each other, —and fed to a combustion chamber (FR) via a burner block (BR), the partial oxidation of the hydrocarbons being carried out in said combustion chamber, —thereby obtaining a first cracked gas stream Ig. The invention is characterized in that —the first cracked gas stream Ig is precooled to a temperature ranging from 100 to 1000° C.Type: GrantFiled: January 15, 2014Date of Patent: February 28, 2017Assignee: BASF SEInventors: Maximilian Vicari, Christian Weichert, Dirk Grossschmidt, Michael Russ, Kai Rainer Ehrhardt, Horst Neuhauser, Michael L.

Patent number: 9290384Abstract: A process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, is disclosed. The process consists of separately preheating and then mixing a first input stream containing a hydrocarbon and a second input stream containing oxygen, supplying the first input stream and the second input stream via a burner block to a firing space, quenching a cracking gas obtained to produce a process water stream and a product gas stream, cooling the product gas stream in a cooling column by direct heat exchange with cooling water, depleting soot in an electrostatic filter, combining all process water streams and passing through soot channels, subjecting the combined process water stream to a cleaning operation by partial vaporization in a one-stage flash vessel to obtain a cleaned process water stream, and recycling the cleaned process water stream into the process.Type: GrantFiled: May 24, 2013Date of Patent: March 22, 2016Assignee: BASF SEInventors: Maximilian Vicari, Christian Weichert, Dirk Grossschmidt, Michael Russ, Mirko Haider, Horst Neuhauser, Michael L.

Patent number: 8506924Abstract: A process for preparing acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, by first separately preheating the hydrocarbon gas and oxygen gas, and then reacting the gases and cooling the products rapidly. The reactor wall is blanketed with a purge gas stream, introduced through a plurality of feed lines. These feed lines deliver purge gas in a vector direction within a 10° angle of the main flow direction of the reactive gas stream. The purge gas is delivered at multiple stages relative to the main flow direction of the reactive gas stream, and the free cross section of the firing space available to the reactive gas stream, at the height of the feed lines of the purge gas stream, is approximately constant.Type: GrantFiled: November 9, 2011Date of Patent: August 13, 2013Assignee: BASF SEInventors: Dirk Grossschmidt, Michael Russ, Peter Renze, Maximilian Vicari, Christian Weichert, Kai Rainer Ehrhardt, Horst Neuhauser, Hans Zapf, Michael L.

Patent number: 6381864Abstract: An improved frame height gauge for race cars includes a substantially hollow housing having an open top end. A spring urges a stop member pivotally mounted within the housing to an extended position in which the stop member projects through the top opening. In use, an individual slides the gauge beneath a frame portion of a race car at a location to be measured, causing the stop member to contact a portion of the race car frame, depressing the stop member against the bias of the spring into the housing to a depressed position in which the distance from a bottom surface of the housing resting on the ground or a floor to the uppermost extending portion of the stop member corresponds to the car frame height at the particular location.Type: GrantFiled: April 11, 2001Date of Patent: May 7, 2002Inventor: Michael L.

Patent number: 6268487Abstract: A method of separating a soluble milk component from milk is disclosed. The method involves the use of tangential flow filtration across a membrane to form a retentate and a permeate, combining the permeate with the original milk sample, and repeating this procedure until the milk has been sufficiently purified. Preferably, the milk is combined with a chelating agent, such as EDTA, to improve the purification efficiency. This procedure is advantageously employed with milk from transgenic animals which have been genetically altered to express exogenous proteins, such as therapeutic proteins, in their milk.Type: GrantFiled: May 13, 1996Date of Patent: July 31, 2001Assignee: Genzyme Transgenics CorporationInventors: Joseph P.

Patent number: 4885811Abstract: A restraint comprises a multiplicity of flexible bubbles which are encased in an air-tight envelope of film material. The bubbles are soft, having a Shore A Durometer rating of 10 or less. When air inside the envelope is withdrawn, the restraint molds to the shape of the animate or inanimate object which it surrounds. The restraint becomes surprising rigid but remains soft and pliable. Another embodiment of the invention is particularly designed as an infant carrier.Type: GrantFiled: May 23, 1988Date of Patent: December 12, 1989Inventor: Michael L. Hayes

Patent number: 4713770Abstract: A system for the detection of broken and worn machine tools which may be employed to protect machine tools using one or more machine tool bits and an automatic sequence of machining instructions comprising one or more machining steps. Piezoelectric load cells translate the force applied between the machine tool bit and the workpiece into electrical signals, one of which is selected, sampled, and processed into a series of force values by an analog module, one average force value for every revolution of a machine tool spindle. For the first pass on a first workpiece by a particular machining operation, force value maxima are learned for each machining step, and broken and worn tool force limits are calculated from these force maxima for each machining step. During this learn pass, each recorded force value is compared against predetermined learn ceiling in order to protect the machine tool.Type: GrantFiled: April 19, 1985Date of Patent: December 15, 1987Assignee: Kinetic Systems CorporationInventors: Michael L. Hayes, Paul S. Mahr, John W. Tippie
