Title: Motorless continuous carbonator
Inventor: RUDICK ARTHUR G
IPC: B01F3/04
Filed: 1990-05-14
Abstract: A motorless continuous carbonator including a double acting piston type water pump (10) driven by a double acting piston type gas pump (12) actuator assembly powered by the carbonating gas. A  connecting rod (18) couples the pump piston (14) with the actuator piston (16) and includes means (64) for operating a toggle switch mechanism (60) for controlling a pair of solenoid valves (40, 52) respectively connected to the pump and actuator assembly for controlling the flow of water and carbonating gas, typically CO2, therefrom and thus deliver still water and CO2 to a semi-permeable membrane carbonator (80). The CO2 gas which initially provides the pumping force is subsequently fed to the carbonator where it is absorbed by the still water to form carbonated water which is then fed to a dispensing unit (102) which may be either a post-mix dispenser utilized either on earth or in a microgravity environment.

Title: Method for the three-dimensional-optical measuring of objects and apparatus for performing such method
Inventor: FEDERAU GREGOR
IPC: A22C25/06
Filed: 1991-01-11
Abstract: ABSTRACT      A method for the three-dimensional measuring of moved objects, e.g. fish fillets, works according to the triangulation method and is based on measuring the sur-face of an object by light-optical line scanning, by means of light beams directed onto said surface.  The scanning lines extend transversely to the direction of progressing of the object.  Each scanning line consists of single points of light and is fanned-up into a line group of a number K of scanning lines formed to extendside by side with regard to the object, the light points of the sequentially formed scanning lines of each line group being shifted by the K-th portion of their spacing in one scanning line. The light points are generated by single light sources which are activated in groups according to the multiplex method.            - Fig. 1 -

Title: Process for leaching of precious metals
Inventor: DIEHL MANFRED
IPC: C22B11/08
Filed: 1991-05-31
Abstract: A process is disclosed for the leaching of gold and silver from ores and ore concentrates through intimate contact of the ore or ore concentrate with an aqueous leach solution containing cyanide. The leach solution has a pH of 8 to 13. The leaching process takes place in the presence of an oxygen-releasing peroxo compound. The separation of the formed cyano complexes of gold and silver takes place in a known manner. During leaching, at least one peroxoborate compound is present, in an effective quantity, as the peroxo compound. The peroxoborate is preferably a sodium or calcium peroxoborate. Compared to previously known leaching techniques in the presence of hydrogen peroxide or calcium peroxide, the leaching process according to the present invention provides a higher and/or faster precious metal yield and/or minimizes the consumption of cyanide and/or oxidizing agent.

Title: Amplification of midivariant dna templates
Inventor: MARTINELLI RICHARD A
IPC: C12Q1/68
Filed: 1991-07-10
Abstract: ABSTRACT     New methods are provided for the amplification of a midivariant DNA containing an inserted target specific nucleic acid sequence(s) to enable detection of the presence of a target nucleic acid sequence in a test sample.  One method employs midivariant  DNA as a template for the synthesis of RNA catalyzed by QB replicase.  Two midivariant DNA/probe conjugates including a nonreplicable portion of midivariant DNA and a target specific nucleic acid sequence (probe) are described.  An amplification method including the steps of hybridization and ligation of the midivariant DNA/probe conjugates followed by replication of the DNA template has enabled detection of less than 200 template molecules.  In a modified amplification method one of the midivariant DNA/probe conjugates further includes a RNA polymerase promoter sequence to enable transcription of the midivariant DNA template into RNA.  The sequential ligation-transcription-replication method enables the detection of a single template molecule.  The detectable molecule(s) are indicative of the presence of the target nucleic acid sequences in the test sample.

Filed: 1992-02-26
Abstract: PROCESS AND APPARATUS FOR MANUFACTURE OF        DUAL TAB MERCHANDISING BAG                  ABSTRACT OF THE DISCLOSURE A bag making machine is modified at the discharge side to include upwardly protruding stacking pins at the stacking area of the severed bags adjacent the open and fused ends of the bag.  The sealed and severed bags are impressed downward over the stacking pins after severing to immediately impale discharged bags at their upstream, open, and trailing end so that severed bags are aligned at their open end in precise registry one stacked on another.  Preferably, and at the time each individual bag is stacked, the bag is fused in the gusset area at the upper open corners of the bag to bags immediately below.  This fusing continues with each stacked individual bag until the total number of bags required for the bag packet is counted.  When the correct number of bags for the bag packet is counted, stacked and fused at the end of each serial stream of bags, spaced apart paired gripping fingers grasp the bag packet at the sealed and stacked bottom ends of the bags constituting the packet.  At substantially the same time, the respective locator or stacking pins retract from the stacking area at the fused open end of the stacked bag packet, and the bag packet is free to move.  The bags are dragged from the stacking area by the bottom sealed portion with the top open portion being the trailing part of the dragged mass down stream to a universal cutting table.  One portion of the cut defines in each bag packet the required handle hole in the front and rear panels of the stacked bags.  The other portion of the cut defines in each bag packet the required cut around the fused portion of the bag to define the bag tabs.     C:WP51\Patent\151382.D

Title: Graphics processing method and apparatus
Inventor: HERROD JOHN A
IPC: G06T15/30
Filed: 1992-05-21
Abstract: ABSTRACT            GRAPHICS PROCESSING METHOD AND APPARATUS      When clipping a graphics element defined by its element border to a viewing window having a window border within which  the  graphics  element  is  to  be  displayed,  it  is necessary to plot closure  lines  along the window border between the points (EX, EN) where the element border exits and enters the viewing window.   This closure line may be plotted along one of two paths between the points and along the window border.  The system detects which of these paths the closure line  should take.   An effectively infinitely extending line from a point  (P)  on the window border is tested to see whether it crosses that portion of the element border outside the viewing window between the exit point and the entry point an odd or an even number of times.   If it crosses an odd number of times then the closure line is plotted to pass through the predetermined point, and if it crosses an even number of times then the closure line is plotted to not pass through the predetermined point.
