Abstract: Inventors:  Matthew W. Frank and Donald E. Oberbeck Title: APPARATUS FOR COLLECTING AND TRANSPORTING             SEAT ENERGY    Abstract of the Disclosure The invention is an apparatus for collecting and transport-ing thermal energy as vaporized fluid.  The vapor will flow from a heat absorption chamber and through a conduit to a point of use where it is condensed.  The heat absorption chamber includes a sump in its lower portion to hold a puddle of fluid.  A heat source directed against the chamber vaporizes the fluid there-within and a replacement fluid supply connects with the chamber to maintain the level of the puddle during vaporization.  The chamber of the preferred embodiment of the invention is an elongated heat absorption pipe mounted horizontally to maintain the puddle at the lower portion of the pipe.  The heat absorp-tion pipe is mounted in a solar collector to receive concen-trated solar energy as from a reflector system.

Abstract: PREFILLED TWO-COMPARTMENT SYRINGE     Abstract of the Disclosure A prefilled, ready to use, disposable syringe wherein a fluid medicament and a diluent therefor are sealed in two separate telescoping syringe barrels.  A medicinal powder is sealed in an outer barrel adjacent the nozzle section by means of a pierceable stopper and the diluent is sealed in an inner barrel between another pierceable stopper and a plunger stopper.  A double-pointed cannula is positioned between the two pierceable stoppers by means of a telescoping guide ar-rangement.  Movement of the plunger stopper inwardly in the inner barrel initially effects a piercing of both pierceable stoppers and intermixing of the medicinal pow-der with the diluent.  Continued movement of the plunger stopper will expel the mixed medicament from the syringe.

Abstract: HIGH DENSITY JET PERFORATING CASING GUN                 ABSTRACT OF THE INVENTION         A high density perforating gun having series con-nected multiple gun housings within which a plurality of jet perforating shaped charges are arranged in spaced apart clusters.  The charges of each cluster are captured in radially spaced apart symmetrical relationship within a mounting assem-bly, and each housing includes a plurality of the mounting assemblies which are spaced vertically apart from one another.          The charges contained within each mounting assembly are ori-ented respective to the charges of the remaining mounting assemblies so that any charge located in one mounting assembly is spaced apart both radially and vertically from the nearest adjacent charge of an adjacent mounting assembly.  This arrange-ment permits a maximum number of shaped charges to be placed within a finite volume.  All of the charges contained within one housing are simultaneously detonated.  The explosive force resulting from a plurality of shaped charges arranged in the above high density manner brings about the unexpected benefit of a more desirable and predetermined perforating pattern dis-tribution as well as achieving deeper penetration into the pay zone while at the same time avoiding misfire of the individual shaped charges.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides a new and useful safety arrangement for use in a pivotable chimney damper in-cluding a damper flap to selectively open and close the outlet from the flue of a chimney.  The damper flap is advantageously pivoted to and includes bias means to urge the damper flap to a normally open position with respect to the frame when un-restrained and carried closure means, which can include flexible pull means to be attached at a first location to the damper flap to pull the damper flap to a closed position against the frame member when the pull means is drawn tight where the pull means can be secured to hold the damper in closed position.          An expansible spring means is attached between the damper flap and the pull means to be pulled to extended position when the damper flap is closed.  In accordance with the present inven-tion a flexible connector is joined to the pull means at a location below the spring means and the damper flap at a second location where pulling the connector urges the damper toward open position where the length of the flexible connector is such that upon selected extension of spring means the flexible connector becomes taught and the force exerted on the second location is in excess of the force exerted on the first location so the damper flap is urged toward open position.

Abstract: ABSTRACT     This invention relates to mechanisms which automatically track the sun in its apparent westward motion across the sky between sunrise and sunset.          Prior art devices have either been too cumbersome and expensive or inaccurate due to a lessening of the com-plexity of such devices.  The present invention overcomes this difficulty by providing a trough type solar collec-tor (21) or other body mounted to rotate about a gener-ally north-south pivotal axis.  A balance weight (25) is supported on an elongated heat sensitive beam (26) anchored at its ends to the westerly side of the collec-tor.  The beam is adapted to bow away from the collec-tor when it is heated by the sun's rays, thereby causing the balance weight to exert westward rotational force on the collector.  A reflector (43) may be positioned behind the beam to concentrate the sun's rays on the beam.  A shutter (34, 35) is fixed to the collector to shade the beam when the collector is pointing toward the sun.  Biasing means (29) such as a fixed weight secured to the easterly side  of the collector, oppose the torque exerted by the balance weight (25) and urge the collector to rotate eastwardly when the beam is unbowed.  Damping means (44) control the speed of westward and eastward rotation of the collector, and a pair of stops (55) limit its westward and eastward travel.
