摘要： An L-shaped digging tooth includes a trapezoidally configured shank having inner and outer sides. A toe portion projects laterally from one of its edges. An angle of about 90.degree..+-.30.degree. is defined between the general plane of the toe portion and the plane of the shank. The shank and toe portion terminate in a common, continuous cutting edge of L or V-shaped configuration having a convex outer boundary and a concave inner boundary. This cutting edge intersects at a leading cutter point, a free inner edge of the toe portion which extends along a line convergent with the shank portion plane. The tooth is hard-faced over a zone adjacent the common leading edge. The invention further relates to an endless chain excavating assembly which includes the described L-shaped teeth arrayed in a specific sequence with, and geometric relationship to, cup-shaped teeth of a known type, with both secured at spaced intervals to an endless chain.

摘要： A cascade CO2 refrigeration system includes a medium temperature loop for circulating a medium refrigerant and a low temperature loop for circulating a CO2 refrigerant. The medium temperature loop includes a heat exchanger having a first side and a second side. The first side evaporates the medium temperature refrigerant. The low temperature loop includes a discharge header for circulating the CO2 refrigerant through the second side of the heat exchanger to condense the CO2 refrigerant, a liquid-vapor separator collects liquid CO2 refrigerant and directs vapor CO2 refrigerant to the second side of the heat exchanger. A liquid CO2 supply header receives liquid CO2 refrigerant from the liquid-vapor separator. Medium temperature loads receive liquid CO2 refrigerant from the liquid supply header for use as a liquid coolant at a medium temperature. An expansion device expands liquid CO2 refrigerant from the liquid supply header into a low temperature liquid-vapor mixture for use by the low temperature loads.

摘要： A drill pipe (10, 100, 220, 200, 210, 250) is disclosed which includes a cylindrical pipe section (12), a box end (14), a pin end (16) and a hydraulic hose assembly (202, 18) or tube (212, 90, 260) inserted between the box and pin ends and extending within the cylindrical pipe section. All, or the majority of drilling fluid passes through the hydraulic hose assembly (202, 18) or tube (212, 90, 260). The interior surface of the cylindrical pipe section (12) may or may not be exposed to the drilling fluid but any corrosion generated by metal-to-fluid contact is generally trapped between the hose or tube and the pipe section. The reduced volume of the hydraulic hose assembly (202, 18) or tube (212, 90, 260) relative to conveying the drilling fluid through the interior of the cylindrical pipe section reduces significantly the waste of drilling fluid, allows the fluid to be pressurized more rapidly to initiate drilling operation, and limits fluid spill damage to the environment.

摘要： A mining apparatus for utilization in recovering coal includes a series of four cooperating legs: a right fore leg, left fore leg, right rear leg and left rear leg. Each leg is formed from a box-like shield. An inflatable bag is provided in each leg. When a particular bag is inflated, the bag expands extending the leg between the floor and roof of the mine. When deflated, the leg retracts. A series of hydraulic rams connect the legs together. These rams may be expanded and retracted as desired to move the support legs relative to one another. In this way the apparatus may be moved in substantially any direction about a 360.degree. arc. A microprocessor controller controls the operation of the apparatus. In accordance with further aspects of the invention, a number of mining apparatus of the type described may be connected together in series to form a line for roof support. In addition, one or more of the apparatus may be connected to a coal conveyor or other mining equipment such as a pneumatic breaker to provide propulsion.

摘要： A refrigeration system for use with refrigerated LT and MT display cases in facilities such as supermarkets, has an absorption chiller that uses waste heat from a nearby source to provide cooling to the refrigeration system to take advantage of the synergy and improve overall efficiency of the refrigeration system. The cooling provided by the absorption chiller may be in the form of a coolant (e.g. water, glycol, water-glycol mixture, etc.) that circulates between the chiller and one or more of a pre-cooler, sub-cooler or condenser in the refrigeration system in a manner that uses waste heat from a nearby source to reduce the need for installed condensing capacity in the refrigeration system and improve thermal efficiency and obtain cost savings.

摘要： The present invention forms sidewall diffusion barrier layer(s) that mitigate hydrogen contamination of ferroelectric capacitors. Sidewall diffusion barrier layer(s) of the present invention are formed via a physical vapor deposition process at a low temperature. By so doing, the sidewall diffusion barrier layer(s) are substantially amorphous and provide superior protection against hydrogen diffusion than conventional and/or crystalline sidewall diffusion barrier layers.
