Title: Method and apparatus for forming corrugated materials using magnetic memory cores
Inventor: MEAD ALBERT R
IPC: B29C70/06
Filed: 1986-09-23
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE A base layer of fabric sheets impregnated with bonding material is deposited on a mold form.  A plurality of parallel spaced hollow cores, fabricated from memory metal alloy, are positioned on the base layer.  An overlying layer is then positioned over the cores and the base layer, the overlying layer also being impregnated with bonding material.  The assembly is subjected to heat and temperature to cure all the layers.  The core is then subjected to a critical temperature causing the core to shrink and permitting its easy removal.  The result is a base layer to which the overlying layer is bonded, the overlying layer characterized by corrugations which stiffen the entire structure and increase its structural strength.

Title: Refrigeration apparatus
Inventor: BARRON EDWARD J
IPC: F25B1/00
Filed: 1987-03-09
Granted: 1992-12-01
Abstract: ABSTRACT                    REFRIGERATION APPARATUS         A novel approach to refrigeration systems is a final condenser/cooler positioned prior to the metering or expansion device controlling the flow of refrigerant into the evaporat-or.  The final condenser/cooler is positioned in the cold air stream flowing through the evaporator for cooling thereby. The final condenser/cooler expands part of the liquid refrigerant flowing from the condenser to cool the remaining liquid as it flows into the expansion or metering device and into the evap-orator.    In embodiments where  there is no  air circulated through the  evaporator,  a variation of the final condens-er/cooler is used where the expanding refrigerant passing from the metering or expansion device to the  evaporator passes through a passage in the main chamber of the final condens-er/cooler to  cool the liquid refrigerant flowing from the receiver.

Abstract: Abstract of the Disclosure A data acquisition apparatus includes two microcomputers interconnected by a shared dual access digital storage device.  One microcomputer obtains the data related to the monitored condition, stores it in the digital storage device, and modifies a status word which is monitored by the other microcomputer.  When the other microcomputer detects a change in the status word, it takes the data from the shared digital memory and moves it into its own memory for subse-quent use or transfer.  The data acquisition apparatus also includes, in a preferred embodiment, analog switches and a digital to analog converter by which external analog devices can be controlled to change the monitored operation.

Title: Air heater for a calender roll diameter controller
Inventor: BOISSEVAIN MATHEW G
IPC: D06C15/02
Filed: 1987-07-07
Granted: 1991-02-19
Abstract: ABSTRACT OF THE DISCLOSURE        An electrical air heater for a calender roll diameter control device is described.  The heater comprises a tube for directing a flow of air along the inside of the tube from a plenum toward an object which is to be heated.  An electrically resistive heating element is mounted inside the tube to heat the flow of air as it flows from the rear to the front of the tube. Since the air is heated by the heating element inside the tube, the air is coolest when it first enters the tube and hottest where it escapes at the front of the tube.  Similarly, the heating element is cooled by the air and is, therefore, hottest near the front of the tube where the heated air escapes.  The hotter front end of the heating element tends to burn out faster than the cooler end of the heating element.  To prolong the life of the heater, openings are provided in the tube wall to admit a flow of cooling air at the hottest part of the heating element.

Granted: 1991-08-20
Abstract: PROCESS FOR PREPARING PULP FOR PAPER MAKING         ABSTRACT OF THE DISCLOSURE This invention relates to a process for producing pulp for paper making. This invention involves the chemical impregnation of wood cellulosic fragments such as chips with an alkaline aqueous liquor having at least one agent acting to provide hydrophilic groups and as an antioxidant capable of protecting the chips against oxidation and which develops hydrophilic groups during the cooking stage. The impregnated chips are cooked using saturated steam in the substantial absence of air at a high temperature and pressure to a K value of at least about 1000 to provide softened chips. The softened chips are refined to produce pulp suitable for paper making. According to a supplementary disclosure, in industrial or semi-industiral applications, the K value can be substantially lower, in the range of 250 plus.

Title: Variable stroke hydraulic cylinder control linkage
Inventor: CARTEE GILBERT A
IPC: A01B73/06
Filed: 1987-08-20
Granted: 1993-05-11
Abstract: VARIABLE STROKE HYDRAULIC CYLINDER CONTROL LINKAGE                  ABSTRACT OF THE DISCLOSURE         A control linkage for varying the length of stroke of a hydraulic cylinder is disclosed wherein a slide member is telescopically received within a bracket member, one of these members being connected to the extension end of the hydraulic cylinder while the other member is connected to the base end.  A limiting mechanism in the form of a series of holes in one of the members alignable with a slotted opening in the other member and a fastener positionable within one of said holes and also through the slotted opening serves to limit the amount of telescopic movement of the slide member from the bracket member.  As a result, the extension of the hydraulic cylinder can be selectively varied according to the preset length of the control linkage.  An alternative embodiment in which a fastener is positionable within the holes externally of the slotted opening provides a two way stroke limiter by  restricting the length of the retraction stroke of the hydraulic cylinder.

Title: Method and system for determining free fatty acid content
Inventor: SCHICK KARL G
IPC: G01N33/03
Filed: 1987-09-01
Granted: 1993-04-27
Abstract: ABSTRACT OF THE DISCLOSURE             The free fatty acid content of an edible oil is measured by a system including a supply of a carrier solution containing an organic solvent for dissolving the oil and a color indicating reagent and an oil sample supply connected to a flow-through colorimetric detector via a sample injection valve. The sample injection valve is movable between a load position wherein a sample stream of the oil is routed to a sample waste collector via a sample loop and a stream of the carrier solution passes through the detector via a carrier solution conduit and a measure position wherein a slug of the oil in the sample loop is introduced into the carrier solution conduit and mixed with the carrier solution prior to passing through the detector.  The free fatty acid in the oil reacts with the color indicating reagent in the carrier solution to produce a color of an intensity indicative of the free fatty acid content which is measured by the detector.  The system also includes a selector valve manifold including up to three different calibration solutions which can be selectively introduced.  A microprocessor operates the sample injection valve and valves controlling the flow of the sample and calibration solutions at programmable intervals and, in response to measurements made by the detector, generates an updated calibration curve for the detector and provides output signals for triggering an alarm, driving a recorder and/or serving as an input to an automatic process control.

Abstract: Abstract of the Invention A knife cylinder having a quick release mounting for a cross-cutting ox perforating knife blade is disclosed. The knife blade is mounted in a longitudinal groove in the periphery of the knife cylinder.  It is held in place against a side wall of the groove by means of a retaining bar which is disposed within the groove.  The retaining bar is normally  urged  against  the  blade  by  compression springs.  In order to change blades, the retaining bar is pivoted away from the blade by means of an operating lever having pins insertable in openings in the outer wall of the retaining bar.  This frees the blade for removal and enables insertion of a new blade.  Endwise clamps are provided with resilient pads interposed between the clamps and the retaining bar to support the retaining bar against dislodge-ment while permitting pivotal movement thereof.
