Abstract: A non-restrictive, constant pressure refrigerant recycling and cooling unit that interrupts the normal refrigerant cycle to permit a lower temperature liquid to enter the expansion device, and thus provide a lower temperature, and therefore a lower pressure gas for delivery to the inlet side of the compressor, which acts to reduce the energy requirement and cost to operate the compressor. This reduction in pressure and temperature also results in lower operating costs and lower maintenance costs and utilizes less refrigerant quantity requirements. A key factor in attaining the above advantages is the construction of the thermal inter-cooler that is so made that no restrictions are specifically inserted in the inter-cooler system, and that direct physical contact exists between the metal compressor inlet suction line and the metal (Cu) refrigerant hot line for optimum heat transfer, and as a result an increased volumetric efficiency and increased capacity occurs by a lowering of the pressure on both sides of the compressor.

Abstract: Apparatus and methods for generating an image of an object utilize a scannable microlaser array to provide a flying spot light source. The microlaser array is scan-energized and imaged onto the object to illuminate the object. Light scattered, reflected, or transmitted from the object is collected and detected, and can be converted to a video-level signal for display on a monitor. The microlaser array can be raster-scanned, scanned in a random access mode, or have at least two laser elements energized simultaneously, to enhance contrast, provide multiplexing, and increase dynamic range. A confocal configuration utilizes a detector array that is scan-read synchronously with the laser excitation pattern.

The current supply to the first capacitor (14) is temporarily interrupted by the interrupting means (48) at least during part of the discharge period. The second capacitor (30) operates as an auxiliary capacitor in which the charge is stored which would otherwise have been supplied to the first capacitor (14). After the interrupt period the charge stored in the second capacitor (30) is supplied back to the first capacitor (14) by the supply means (50). In this manner there is achieved that substantially no charge current is lost during a total period of time of a charge and discharge cycle. In the total period of time the whole charge current of the current source ends up in the first capacitor, so that tolerances in the discharge period no longer affect the oscillation frequency of the sawtooth oscillator. <IMAGE>

Abstract: Iron ore concentrate is converted to magnetic gamma hematite in an autogenous roasting operation which is self-sustaining. The iron ore concentrate is preheated and contained magnetite is oxidized to hematite. Hematite is reduced to magnetite using carbon monoxide. After cooling, the magnetite is oxidatively exothermically converted to magnetic gamma hematite. The thermal energy resulting from the latter step is recycled to the preheating and reduction steps while thermal energy resulting from the cooling step also is recycled to those steps. The magnetic gamma hematite may be subjected to magnetic separation to produce a very low silica high purity iron oxide concentrate, which may be blended with high silica concentrate to provide a pellet feed for making blast furnace feed pellets. <IMAGE>

Abstract: An outer container for holding a material, such as a food, beverage or medicine with a sealed thermic module inside the container. The thermic module contains chemical reactants that mix upon actuation of the container by a user. Mixing of the reactants produces an exothermic or endothermic chemical reaction, depending upon the reactants selected. The contents of the outer container surround a portion of the outside surface of the thermic module, thereby facilitating conduction of heat. The thermic module has a hollow module body that is closed at one end and a module cap that seals the other end of the module body. The module body contains the solid reactant, and the module cap contains the liquid reactant. The module cap has a tubular section with a flexible member closing one end and a breakable barrier closing the other end. With the exception of the barrier, the cap is of unitary construction. The cap has one or more integrally formed prongs extending from the inner surface of the disc toward the barrier. The prongs move in an axial direction toward the barrier and may also spread apart radially when the outer surface of the flexible member or an actuator connected to it is depressed by the user's finger. The dual motion of the prongs in both axial and radial directions promotes complete puncturing of the barrier and thus fast mixing of the reactants.
