Title: Methods and articles for collecting a refrigerant vented from a heat exchange system
Inventor: KENEAVY BERNIE
IPC: B01D8/00
Filed: 1989-10-31
Abstract: METHODS AND ARTICLES FOR COLLECTING A REFRIGERANT VENTED FROM A HEAT EXCHANGE SYSTEM            Abstract A Freon type refrigerant, which is vented from a heat exchange system, such as an air-conditioner, is transferred directly from the exhaust valve of the heat exchange system through a tube to a collecting cylinder or tank.  The outer metal side walls of the collecting tank are wrapped with a chemically activatable cold wrap.  The cold wrap may, for example, contain therein a rupturable pouch having a chemical blend of ammonium nitrate and urea to isolate same from water within the cold wrap.          Upon rupturing of the pouch, the chemical blend is dissolved in the water and an endothermic reaction is initiated.  As a result, the heat within the tank is absorbed therefrom by the cold wrap causing the temperature and pressure inside of the tank to drop.          This permits substantially all of the refrigerant in the heat exchange system to be transferred into the chilled tank in a condensed or liquid state.          Alternately, a series of coils in contact with a chemically activatable cold wrap can be used to also assist the refrigerant to flow from a heat exchange system into a collecting tank in a condensed or liquid form.

Inventor: JACOBS ROBERT S
IPC: C22C1/05
Filed: 1989-11-02
Abstract: A hard metal composite is formed from a mixture of two or more pre-blended, unsintered hard metal composites in which the properties of each constituent are different.          The constituent components are selected so that they have different grain sizes, different binder contents, different metal carbide or binders, or some combination of these.  Primarily, the constituents are chosen on the basis of their properties and compatability, and are chosen to utilize the superior properties of one of the constituents without detrimentally affecting the desirable properties of the other.  As an example, a pre-blended composite having a superior hardness may be dispersed in a second composite having a superior toughness with the resultant material having a hardness which approaches that of the harder constituent yet maintaining the toughness of the matrix constituent.

Title: Machine for forming cylindrical bales of crop
Inventor: PFRIMMER ERNEST
IPC: A01F15/10
Filed: 1990-01-16
Abstract: MACHINE FOR FORMING CYLINDRICAL BALES OF CROP          Abstract of the Disclosure A baler for forming large cylindrical bales of crop material has a baling chamber in which the crop is rolled into a bale by oppositely moving runs of side-by-side belts.  A windrow of crop material is fed through an inlet of the baling chamber by means of a pick-up which lifts the windrow of crop and delivers the same to a feeder fork mechanism which in turn moves the crop into the inlet.  Crop enters the baling chamber between a roll, over which the belts are trained, and a growing bale core.  In order to reduce plugging of the crop at the inlet, the roll has discs rigidly mounted on it between neighboring belts.  These discs each have and outer edge which is approximately sinusoidal in configuration and the peaks of the undulations extend outwardly beyond the thickness of the belts.  The effect of the discs is both to grip the crop better and to raise the bale core slightly to provide easier access to the chamber for the crop.

Filed: 1991-02-13
Abstract: ABSTRACT.       METHOD OF AND APPARATUS FOR DETECTING MISFIRE.     In order  to detect misfire  in an  internal  combustion engine, engine speed is determined by measuring the time of passage of a crankshaft disc from a first position to a second position during every revolution. A detection circuit takes the reciprocal of  the measured times of passage to form a series of engine speeds and forms the difference  between  consecutive  engine  speeds.    These differences are compared with a threshold to signal a misfire when the threshold is exceeded.

Abstract: A method of continuously forming an extended length of a unitary structure includes the following steps.      A supply of a porous flexible blanket is provided.      A high viscosity flowable solidifiable mixture is con-tinuously flowed simultaneously into an entire contin-uously moving width of the porous flexible blanket.      Pressure is applied against the treated blanket to form a uniform matrix therewith. The rate of advance of the blanket is monitored. The rate of alliance is co-ordinated with the flow rate of the mixture into the blanket and with the pressure applied thereto: A sub-stantially flat non-porous flexible envelope is posi-tioned along the length of the treated blanket. The envelope/blanket combination is positioned along a de-sired path. A pressurized gas is introduced into the envelope. The envelope is inflated to move the treated blanket into a final configuration, The non-porous envelope maintained in an inflated state until the treated blanket is set in the final configuration.  Also a unitary structure formed according to the above method.
