Granted: 1983-12-13
Abstract: ABSTRACT OF THE DISCLOSURE A power plant for generating electrical power comprises opposed piston assemblies each at the end of a rack and pinion mechanism conformed to pass through a linear inductor. Thus on each piston firing stroke the linear translation of the rack is used to produce electrical power.          This is achieved by an interdigitated magnetic structure attached to each rack. In this manner a linear inductor is utilized to take benefit of each stroke in the course of generating electricity.  Each pair of opposed pistons includes its own throttle control system, thus allowing for convenient balancing of the total power.  The throttle control system operates a mixture mechanism which combines combustion air with fuel and water to form a charge which is injected into the firing chamber.

Granted: 1984-09-04
Abstract: ABSTRACT OF THE DISCLOSURE A hand labelling apparatus which imprints and despenses pressure-sensitive labels adhering to a carrier tape, comprises a feed means under the control of an operating lever pivotal between a rest position and a working position which draws the carrier tape stepwise about a peel edge. In each working cycle a pressure-sensitive label on feeding in a forward direction detaches from the carrier tape at the peel edge and moves into a dispensing position.  In each working cycle at a printing zone remote from the peel edge oppositely to the forward direction a printing mechanism produces an imprint on a pressure-sensitive label.  The feed means comprises a tape feed mechanism which is driven by the operating level.          On movement of the operating lever from the rest position to the work position, the feed mechanism moves the carrier tape in the return direction opposite the forward direction through at least a distance which is equal to the distance of the peel edge from the printing zone.  On the return of the operating lever from the working position to the rest position the feed mechanism moves the carrier tape in the forward direction through the same distance plus one label length.

Abstract: ABSTRACT OF THE DISCLOSURE      A communication  multiplexer stores the receive and transmit channel   numbers  of   input/output   devices   coupled  to  the multiplexer by communication lines in a first in-first out (FIFO) memory.   The  input/output  devices are  polled by  sending  the channel  numbers from the FIFO  to the  input/output devices.  An input/output  device  requesting service  responds to its channel number.    The   remaining  channel   numbers  in  the  FIFO  are recirculated  to give the  receive channel numbers priority over the transmit channel numbers.  This gives high priority to a most recently used receive channel operative in a burst mode and equal priority to all transmit channels.

Abstract: ABSTRACT OF THE DISCLOSURE:         Apparatus for separating liquid components from solid components of a liquid-solid mixture, comprising a hollow press barrel defining a relatively low pressure feed region and a relatively higher pressure pin-barrel region, and a drivable screw rotatable in said barrel, said screw having a longitudinal axis, a base, and a screw flight helically disposed thereon, said screw flight being formed with axially spaced gaps extending radially entirely around said base in the areas of said gaps.  A plurality of radially inwardly directed pins passe into the pin-barrel region of the press barrel, the radially inner ends of the pins extending substantially to the base of the screw in the regions of the axial gaps and forming narrow radial gaps with the screw base.  The presence of the pins in said pin-barrel region effects a substantial buildup of pressure in such region thereby resulting in the release of liquid from the mixture, the diameter of each the pin being less than the length of the adjacent axial gap so as to permit rota-tion of the screw.  Each said pin has an axially extending throughbores including a first, open end adjacent the base of the screw and a second end remote from the screw base, the throughbores being at substantially atmospheric pres-sure.  The radial dimension of the radial gaps is such that the liquid can be extracted and discharged through the throughbores without any substantial drop in pressure in the pin-barrel region and without clogging of said through-bores.  Discharge network means, also at substantially atmospheric pressure, are in fluid flow communication with the second end of each said throughbores.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides a process for measuring the coating quantities contained in coating layers deposited on both sides of paper, cardboard or equivalent material in which both coating layers contain the same component emitting characteristic radiation.  In the case most commonly encoun-tered, both coating layers consist of the same coating material.  In the procedure two functionally mutually inde-pendent radiation source/detector pairs are used, between which the coated paper or equivalent is placed.  Separately which each radiation source/detector pair excitation of fluorescent radiation in both coating layers under measure-ment is effected and measuring of the total intensity of the excited radiation present at the detector is effected.  If the base weight of the paper or equivalent material is known, the coating rates are calculable from the results of measure-ment obtained.  The said base weight is most advantageously measured before the coating step with the aid of a separate source of radiation and a transmission detector.

Abstract: METHOD FOR AFFINITY PURIFICATION OF HYBRIDOMA ANTIBODIES          Abstract of the Disclosure An efficient process design for purifying large quan-tities of specific antibodies by affinity chromatography is disclosed.  By utilizing the process strategy described, large scale production of highly purified hybridoma antibodies and other proteins becomes feasible.           The initiation of the process centers on production of hybridoma proteins which bind to a commonly available inexpensive protein such as human serum albumin (HSA) with which large quan-tities of a protein such as mouse immunoglobulin can be isolated by affinity chromatography.  The mouse immunoglobulin is cova-lently linked to an inert matrix, such as Sepharose beads and this affinity reagent is used to purify a large quantity of a hydridoma protein such as rat anti-mouse IgG antibody.  This rat anti-mouse IgG antibody can then be linked to sepharose beads and can be used as a general affinity reagent for the purification of any mouse immunoglobulin.
