Abstract: The present invention is a liquid cooled electric machine (10) having enhanced cooling of the end turns (22) by providing intimate contact between the end turns and coolant fluid flowing through a first annular flow channel (34) and a second annular flow channel (50). Furthermore, a cylindrical liner (62) which is force fit within the annulus of the stator 12 forms part of the first and second annular flow channels and further provides support against radially inward deflection of the end turns (22). Furthermore, the invention is a cooling system (200) for an exciter generator in a self-excited electric power generator which has a liquid coolant circuit (216) which splits coolant flow between an inside surface (222) of a fullwave rectifier assembly (214) and an outside surface (226) of the fullwave rectifier assembly which absorbs heat from the rotor of the exciter generator.

Abstract: Disclosed is a protective carrying apparatus of puncture-resistant material sides which mates with medical waste containers. The apparatus acts as a barrier between the person handling the medical waste container and contaminated sharp objects which may protrude through the container. The apparatus may be readily employed in hospital and health care waste handling programs to provide a prophylactic protection against the transmission of infection or injury due to contaminated sharp objects which may be inside medical waste containers.

Abstract: This invention relates to a thermal energy device for receiving and storing externally applied thermal energy. The thermal energy device includes a thermal energy receiver which is adapted to receive the intermittent externally applied thermal energy to heat and expand a fluid in the thermal energy receiver. A thermal energy store is in fluid communication with the thermal energy receiver to receive and store the heated and expanded fluid received from the thermal energy receiver. The thermal energy store is responsive to the receiving and storing of the heated and expanded fluid such that, as the heated and expanded fluid is received and stored, the thermal energy store delivers more of the fluid to the thermal energy receiver to continue accommodating the intermittent externally applied thermal energy.

Abstract: Lack of uniformity in liquid cooling the end turns of a dynamoelectric machine can be avoided in a structure including a stator (14) having a rotor receiving opening (22) and opposed end faces (18) and (20). Slots (24) in the stator (14) extend between the end faces (18) and (20) and a plurality of electrical conductors (28) are located in each of the slots (24) such that interstices exist between adjacent conductors (28) and define coolant flow passages within the slots (24) from one face (18) to the other (20). The conductors (18) exit the slots (24) at the end faces (18 and 20) and are redirected into another one of the slots (24) to thereby define end turns (30) at each end face (18 and 20). Two tubes (32 and 34) are located on each end turn (30) and adjacent ends (36, 38) of each tube (32, 34) are slightly spaced to defined a gap (40) and remote ends (42, 44) of each tube (32, 34) are sealed to the associated end face (18, 20) about the periphery of the associated slot (24).

Abstract: A protective apertured shield for use about an inlet to a solar apparatus which includesd a cavity receiver for absorbing concentrated solar energy. A rigid support truss assembly is fixed to the periphery of the inlet and projects radially inwardly therefrom to define a generally central aperture area through which solar radiation can pass into the cavity receiver. A non-structural, laminated blanket is spread over the rigid support truss in such a manner as to define an outer surface area and an inner surface area diverging radially outwardly from the central aperture area toward the periphery of the inlet. The outer surface area faces away from the inlet and the inner surface area faces toward the cavity receiver. The laminated blanket includes at least one layer of material, such as ceramic fiber fabric, having high infra-red emittance and low solar absorption properties, and another layer, such as metallic foil, of low infra-red emittance properties.

Abstract: The subject filleting knife has a cutting element having two cutting edges starting from the juncture of the blade element and handle and extending to a point part way along the element at which the two edges merge into a single edge. The knife thus serves the functions of both single blade and double blade filleting knives. It allows a significant improvement in the efficiency of the process of filleting in terms of time, skill and care required relative to the quality of the fillets produced and reduction of wastage. Safety is enhanced.

Abstract: A lance for blowing oxygen from above into a ladle of an iron foundry has a nozzle head with at least four main tuyeres of larger diameter and as many ancillary tuyeres of smaller diameter, the larger tuyeres serving to blow into the melt for decarburizing the metal while the smaller ones promote afterburning of the evolving carbon monoxide just above the melt surface. The axes of the main tuyeres are inclined to the nozzle-head axis at an angle of about 14.degree. to 17.degree. while the axes of the ancillary tuyeres have an angle of inclination exceeding that of the main tuyeres by about 30.degree. to 50.degree.. In order to slow down the air flow through the ancillary tuyeres with reference to the surface-penetrating jets of the main tuyeres, the former are provided with inner peripheral inlays or grooves of annular or helicoidal shape.

Abstract: A scooter vehicle has a chassis, and a front wheel mounted on the center line of the chassis, a rear wheel mounted on the chassis, and a steering column attached to the front wheel. A pair of ratchet gears are connected one to each of the rear wheels. A platform is rotatively mounted on the chassis. The platform has front and rear foot portions mounted with an angle of less than 180.degree. between them. First chain means connects the front of the platform for driving one of the ratchet drive wheel gears and second chain means connects the rear of the platform for driving the other of the ratchet drive wheel gears.

Abstract: A push-button mechanism for tuning a radio receiver includes push-buttons that are actuable to rotate a turrent tuner to different extents for station selection. The side of each push-button contacts one end of an individual lever to pivot it through a predetermined angle upon actuation of the push-button. The other end of the lever contacts one of several projections on a bar which extends transversely of the push-buttons and which is coupled via rack and pinion gearing to the drum of the turret tuner. The levers of the different push-buttons have different orientations with respect to the bar so that although each lever is pivoted through the same angle, longitudinal displacement of the bar effected, and hence the setting of the turret tuner, depends upon which push-button is actuated. Upon actuation of a push-button, the bar is locked in its displaced position by means of a leaf spring, and the drum is then locked in position by means of a projection that engages in one of several notches in the drum.
