Abstract: A reversible vapor compression system having control means associated therewith for automatically routing refrigerant through the heat exchangers in response to a system mode of operation to produce optimum system performance when the system is called upon to produce either heating or cooling.

Abstract: A heat exchanger is provided with pivotally mounted, angularly disposed, cooling modules or cores so as to increase the cooling capacity of the heat exchanger and, at the same time, to have a self-cleaning capability for the modules or cores. The angular disposition of the modules or cores results in a larger effective frontal area to the heat exchanger thereby increasing the cooling capacity of the heat exchanger. The angular orientation of adjacent modules or cores slightly compresses the oncoming air which provides an increased level of cooling for the cores. Each module or core can be pivoted about an axis a sufficient amount such that the opposite surface of each module or core is swept by the oncoming air which passes around and through the modules or cores in a direction opposite to an initial pass of said air whereby the modules or cores are cleaned by the reverse flow of air.

Abstract: A method of selective plugging of undesirable high permeability streaks and channels in oil-bearing reservoirs during high temperature (250.degree. F. or higher) injection recovery processes such as steamflooding, underground combustion, flooding of a naturally occurring high-temperature reservoir or the like. Improved sweep efficiency can be effected by injecting a gel-forming solution consisting essentially of sodium or ammonium lignosulfonate and water or brine in the absence of other gelation promoters and then allowing the high temperatures of the underground formation to promote gelation. Optionally, a precooling water injection step can be used prior to placement of the gel-forming solution. This system has the advantage of gel times which are sufficiently long at temperatures in excess of 250.degree. F. to permit placement of large volumes characteristic of commercial use. This method is particularly useful in selectively forming firm, strong gels in thief zones for steamflooding recovery operations.

Abstract: An impact rock breaker includes detachable mounting means and latching means operative to mount the rock breaker on the stick of a backhoe or excavator adjacent the bucket such that the rock breaker can be pivoted between a non-operative position out of the way of the bucket to permit normal operation of the bucket and an operative position latched to the bucket for movement with the bucket for normal operation of the rock breaker.

Abstract: This invention relates to a method and apparatus for fabricating continuously a solified elongated rod or hollow shapes of various geometric cross sections of fiber reinforced plastic having a smooth surface. A plurality of strand-like fibers are wetted with a liquid, heat-hardenable plastic, the fibers are collected together into a plastic-wetted bundle, the bundle is continuously, in intermittent steps, passed through an elongated die, the die being heated in sequential zones of progressively increasing temperature so as to harden the plastic by the time the bundle emerges in rod form from the die. The bundle is moved through the die intermittently, dwelling for a predetermined time at rest, then moved an incremental distance, permitted to dwell again, until the hardened bundle eventually emerges from the die. The various heated zones of the die serve to initiate and carry the hardening of the plastic to a predetermined point at which the bundle is moved and the cycle is repeated.

A support band is specifically configured to be disposed in surrounding relation to the upper portion of the wearer's head in somewhat conventional fashion. A visor is at least partially defined by a flexible material pouch specifically configured to have mounted therein a visor support element so as to provide outward extension of the visor relative to the face or other predetermined portion of the wearer's head wherein the visor support element can be readily removed from the pouch to allow washing of the entire article of apparel or alternately for folding over of the visor portion about itself in surrounding relation to the support band so as to essentially function as a band used primarily to absorb perspiration from the head of the wearer.

Abstract: A means and method for designing and fabricating garments, particularly suited for the home sewer. Using a stretch body suit having cushioned areas, muslin panels are draped on the individual wearing the suit to conform to the individual shapes and contours. The muslin panels form a basic pattern which include front and back portions of a bodice, a basic fitted skirt, and basic pants. The pattern is used to provide a corresponding plurality of oak tag slopers which may be manipulated to provide a variety of designs relative to the individual slopers. These slopers, manipulated into new designs, are used to make paper patterns which are in turn used as a guide in cutting actual garment sections which are stitched together to provide a completed garment which fits the individual with little or no alteration.

Abstract: A pulsatile flow cardiopulmonary bypass pump for use outside of the body during cardiac surgery and/or in the period immediately thereafter is disclosed. A grooved spinner is motor driven through a fluid coupling which enables idling of the spinner during diastole. The shell of the pump has a roof to which the spinner drive motor is attached, and the roof can move axially of the shell body and is biased resiliently in one axial direction. The roof of the shell moves as a function of duration of systole and magnitude of afterload, reducing stroke volume in the presence of high afterload. A groove rider having a friction reducing ball bearing drives a ring follower housing during rotation of the spinner.

Abstract: The prosthesis disclosed is an unrestrained or hingeless elbow prosthesis including a humeral implant component and an ulnar implant component. The metal humeral component is comprised of an elongated stem with a substantially cylindrical articulating surface on the distal end of said stem wherein said cylindrical articulating surface is convex such that the diameters of the end surfaces of the cylindrical shape are smaller than the diameter about the midportion of the cylindrical shape. The ulnar component is comprised of a metal retainer and a polyethylene bearing. The metal retainer includes an elongated stem attached to a metal base such that the stem depends from the base and anatomically curves slightly outward or laterally from the base.The polyethylene bearing is slidably engaged to the metal retainer and locks into position on the retainer. The polyethylene bearing contains a concave cylindrical cavity for receiving the convex cylinder of the humeral component.

Abstract: A demand type flush tank control for saving water by the utilization of a water release valve of the flapper type in the water storage tank of a toilet, with such flapper valve being non-buoyant such that it will close off the flow of water from the tank into the toilet the instant the flush handle has been released by the user. In this way, the use of the entire contents of the tank is prevented, except on those occasions where a full tank is actually needed. My novel flapper valve has no air pocket below the sealing area, as do conventional flapper valves, and it is non-buoyant such that it does not ever become free floating. Accordingly, my novel flapper valve readily returns to its seat the moment the toilet handle is released, thereby effecting a daily savings of many gallons of water during each controlled use.

The segments are hingedly joined together. On one rectangular face of the cushion member the two sections bounding the center line are hingedly joined in the plane of the one rectangular face. On the other rectangular face, the two sections in each square portion are hingedly joined in the plane of the other rectangular face.

Abstract: A method and apparatus for cleaning bee culture nests or hives of the spirally wound type, which are formed by spirally wound strips of corrugated and separator material. Bee larvae are removed and the nests cleaned by unwinding and separating the corrugated and separator strips, mechanically cleaning the strips and rewinding them to form a hive for reuse. The mechanical cleaning of the corrugated strip is accomplished by a plurality of fingers arranged to move through the flutes on each side thereof to remove the bee larvae. Scrapers contact both sides of the separator strip to remove the remaining adherent nesting material or "debris".
