Granted: 1993-06-29
Abstract: ABSTRACT            A gas mixture including sulphur dioxide is recovered from sulphate waste material by burning a fuel to form a flame zone, introducing sulphate waste material into the zone and introducing pure oxygen or other oxygen-rich gas into the flame zone to support combustion of the fuel and to generate a flame of sufficient temperature to crack solid sulphate waste material and thereby liberate sulphur dioxide therefrom.  Solids exiting the flame zone are separated from the gaseous combustion products.  The sulphate waste material may be taken from a plant for making titanium dioxide pigment by the sulphate route.

Title: Process for purifying 4-hydroxyacetophenone
Inventor: MURPHY CARL D
IPC: C07C45/00
Filed: 1987-07-21
Granted: 1990-11-13
Abstract: Abstract A process is provided for the distillation of a composition containing 4-hydroxyacetophenone and hydrogen fluoride in the presence of an alkane assisting solvent having from 4 to 16 carbon atoms e.g. n-hexane or n-octane.  The process is carried out to obtain an overhead vapor containing alkane solvent and most of the hydrogen fluoride in the feed, and a liquid residue containing most of the 4-hydroxyacetophenone in the feed.  The overhead vapor is condensed to form two immiscible phases, one containing a preponderance of hydrogen fluoride and the other a preponderance of alkane solvent, with the latter phase being returned to the distillation as reflux.  The liquid residue also separates into two immiscible layers, one containing most of the 4-hydroxyacetophenone in the feed which is recovered and the other a preponderance of alkane solvent.

Title: Method suitable for producing expanded food products
Inventor: SCHAAF HEINZ-JOSEF
IPC: A23P1/14
Filed: 1988-04-08
Granted: 1995-04-25
Abstract: In a method suitable for producing expanded food products, whereby a dough exits from the nozzle of an extruder and the extrudate undergoes further processing in a hot medium, the extrudate  is,  after  exiting  from  the  nozzle,  kept  at  a temperature that corresponds more or less to the temperature of the dough during extrusion and whereby further processing takes place immediately after extrusion.  In particular, the dough can be extruded directly into hot oil or fat.  Since after extrusion the extrudate does not cool off, especially through evaporation of water, the extrudate is, during the subsequent processing stage, permitted to further expand, the result of which being a food product whose texture is identical to that of food products which, following extrusion and prior to processing in a hot medium, undergo a drying process.

Abstract: ISDN INTERFACE TRUNK CIRCUIT                     ABSTRACT OF THE INVENTION          This circuit is a trunk type interface circuit which interfaces between duplicate copies of an ISDN system and T-carrier facilities.  The circuit is controlled by a digital signal processor which has a 16-bit wide data bus.  The digital signal processor is capable of supporting various Zero Byte Time Slot Interchange (ZBTSI) techniques.  Also included is an administrative microprocessor which collects data concerning the operation of the trunk circuit and transmits this information to the ISDN system.  The administrative microprocessor also receives information from currently unused data bits in the input bit stream from the ISDN system.  The trunk circuit includes one receiver which collects and stores data transmitted by the ISDN system.  Another receiver collects and stores data transmitted via the T-carrier facilities.  The trunk circuit also includes two transmitters.  One transmitter converts previously formatted data to T-carrier compatible data and transmits the data via the T-carrier facilities.  The other transmitter converts reformatted data received from the T-carrier facility to data compatible with the ISDN format and transmits this data to the ISDN system.  The memory of this circuit includes a dual port random access memory which provides for nearly simultaneous access by two separate input/output controllers.

Abstract: ABSTRACT        An apparatus for self-service check out which calculates, within a main computer, the cumulative total weight of items, based on pre-determined and pre-programmed weights, and compares the computerized cumulative total weight to the weight determined by a second weigh scale means which determines the total weight of all items placed in a receiving container means.  Items scanned by electronic means are itemized by the computer which directs the printing of an itemized register tape.  Fraudulent mishandling of items by the customer is overcome by communication between the computer and ending weigh scale when weights calculated by each correspond within a determined tolerance level.  In an alternate embodiment, a weighing of pre-scanned items in total is required to correspond with the total weight calculated by the computer and the end weigh scale, within a determined tolerance level.
