Abstract: DIE FOR CUTTING PAPER, CLOTH AND THE LIKE         AND METHOD OF MAKING SAME                ABSTRACT       A die for repetitively cutting shapes out of material  such  as  paper  and  cloth  includes  a continuous,   seamless   metal  wall  defining  a central  opening  having  a  predetermined  shape substantially the same as a shape it is desired to cut.  A cutting surface is disposed at the top of the metal wall,  the cutting surface defining the outline of the shape it is desired to cut.          Such dies are formed by cutting a die blank out of a block of metal, the outline of the die blank corresponding  generally  to  the  shape  it  is desired to cut.  At least part of the interior of the die blank is removed to form a modified die blank with a central opening having substantially the  same  shape  as  the  shape  it  is  desired  to cut.  A cutting edge is formed on one surface of the  modified  die  blank  adjacent  the central opening by electric discharge machining.

Granted: 1991-01-08
Abstract: MICROBIOLOGICAL DESULFURIZATION OF GASES ABSTRACT OF THE DISCLOSURE     There is disclosed a method for desulfurizing gases by microbiological techniques which involve the use of chemoautotrophic bacteria of the Thiobacillus genus to convert sulfides to sulfates either as a sulfide removal process or as a process for producing biomass.  More specifically, the invention involves the use of Thiobacillus denitrificans under anaerobic conditions to oxidize sulfur compounds such as hydrogen sulfide to sulfate compounds.  The process may be carried out by various techniques such as in a continuous bioreactor system using an immobilization matrix.  The method is particularly applicable to treating natural gas containing hydrogen sulfide and producing a biomass byproduct.

Abstract: ABSTRACT         This invention generally relates to a new method and apparatus for the fast thermal processing (such as fast pyrolysis, rapid cracking) of carbonaceous materials (feedstock) involving rapid mixing and heat transfer in a novel reactor design.  The heat is transferred to the feedstock from hot particulate solids which are injected into the reactor through several inwardly directed, impinging jets.  The feedstock is then injected axially into the reactor in the centre of the impinging jets to form a dense turbulent central jet resulting in rapid mixing and heat transfer.

Title: Electronic servo control of glass gob distribution
Inventor: GRANT MARTY J
IPC: C03B9/40
Filed: 1987-10-15
Granted: 1993-02-16
Abstract: ABSTRACT             ELECTRONIC SERVO CONTROL   OF GLASS GOB DISTRIBUTION     Method and apparatus for electronically control-ling a servo motor drive for glass gob distribution apparatus, to provide accurate high speed motion of one or more scoops.  At the set-up stage, the opera-tor adjusts the scoop position with respect to each trough to align scoop and trough in a straight line. During automatic operation, upon receipt of a MOVE command a motion control computer provides digital output signals to move the scoops through a pre-scribed motion profile, such profile having suitable characteristics to move the scoops over various distances without vibration or overshoot.  A digita-lized cubic-parabolic-cubic (CPC) curve or similar cam profile is scaled to the amplitude and direction of the required motion, and the motion profile com-puter outputs command signals on a point-by-point basis over the time span of this stored motion pro-file. Such time span is designed to provide suffi-cient dwell time to allow the gobs to traverse the scoops.  This motion sequence is reiterated for each successive receiving trough according to the pre-scribed firing order, using the prior target loca-tion to define the starting location of the succeed-ing scaled motion profile.

Title: Method for storing a parcelwise divided digital data base as well as of addressing a data parcel in a mass memory, and apparatus for carrying out the method
Inventor: DRIESSEN LEONARDUS M H E
IPC: G06F17/30
Filed: 1987-10-20
Granted: 1991-11-12
Abstract: Abstract Method for storing a parcelwise divided digital data base, as well as of addressing a data parcel in a mass memory and apparatus for carrying out the method.           A database is stored in a mass memory. For this purpose, it is first divided into main cells and then into base cells according to a predetermined regular division pattern. Each base cell is then checked to see whether its data content is sufficient to occupy substantially completely a storage parcel having a predetermined capaci-ty. If this is the case, the base cell is thus accommodated in a storage parcel; if this is not the case, adjacent base cells are grouped until a storage parcel is occupied substantially completely. The operation of addressing a storage parcel is effected by the use of a main cell table in which address pointers are stored, each of which points to a base cell table. In the base cell table, an index is given for each base cell and this index indicates in which storage parcel the relevant base cell is accommodated. Each of these indices indicates a location in a data parcel list at which an address indicator is present, which in-dicates the location at which the relevant parcel is stored in the mass memory.

Abstract: ORBITAL SHAKER Abstract of the Disclosure An orbital shaker apparatus which has a tray for cyclic motion is flexibly suspended from a frame which is flexibly suspended from a plurality of stationary supports.  The flexible suspension constrains the tray to move only translationally along one axis with respect to the frame and constrains the frame to move only translationally along one axis perpendicular to the tray movement axis.  A single chip microprocessor is used to scan, input store, display and control the speed, duration and control functions for the orbital motion. Embodied in the software of the microprocessor is a real-time closed loop speed control which monitors the actual speed of the orbital motion thru an interrupt facility by calculating the duration of pulses received from an optoelectric sensor.  The measured pulse duration is digitally compared to the desired duration and a digital control signal is provided to drive a DC motor which is directly coupled to the drive shaft which imparts the motion.  A set speed mode and a reversing mode are selectable by an operator to provide different means for agitation.

Abstract: ACTIVE PAPER DROP FOR PRINTERS                 ABSTRACT OF THE DISCLOSURE      An active paper drop mechanism for ink-jet printers is provided.  The mechanism comprises a pair of opposed, movable rail members associated with opposed walls of a horizontally-disposed output collection tray for receiving sheets of printed media.  Each rail member is provided with return spring that act to maintain the rails in a closed position.  In that position, the rails support a sheet of the print medium during the printing operation, thus giving the ink on the previously printed-on sheet time to dry.  The rails are provided with a wing member and are pivotally secured in the floor of the output tray, with the pivot point spaced inwardly from the wing member.  Downward pressure against the wing member thus causes the rail to rotate outward from its closed position, into a recess provided in the side of the output tray.  This provides sufficient clearance for the sheet to drop into the output stack.  Upon release of the downward pressure, the spring causes the rail member to return to its original closed position.
