Abstract: In various aspects, methods of making perovskite manganese oxide particles are provided as well as perovskite manganese oxide particles made therefrom. The perovskite manganese oxide particles exhibit a strong magnetocaloric effect, making them well suited for applications in power generation and magnetic refrigeration, especially at or near room temperature. The methods can include forming an aqueous mixture of (i) a low-molecular-weight polymeric polyalcohol gel precursor, (ii) a stoichiometric amount of metal salts or hydrates thereof, wherein the metal salts or hydrates thereof comprise at least a Manganese (Mn), and (iii) a polybasic carboxylic acid; polymerizing the aqueous mixture to form a gel containing perovskite manganese oxide nanoparticles entrapped therein; and calcining the gel to remove at least a portion of organic material in the gel and form the perovskite manganese oxide particles.

Abstract: An overfill containment system for a tanker has an overflow tank having an inlet selectively fluidly coupleable to a vapor-release system of the tanker and an outlet selectively fluidly coupleable to an input/output port of the tanker and to an inlet/outlet of a tank of the tanker. The input/output port of the tanker and the inlet/outlet of the tank are for liquid, e.g., hazardous, volatile, and/or flammable liquid, gasoline, oil, fuel, fuel oil, chemicals, etc.

Abstract: One aspect of the present invention relates to a spindle motor manufacturing method for forming an oil repellent film which prevents a lubricating oil from flowing out, on a predetermined area adjacent to a hydrodynamic bearing, the predetermined area being located on at least one of a stationary member and a rotating member. The spindle motor manufacturing method mentioned above comprises a step of supplying an oil repellent solution by a supplying portion onto a part of the predetermined area for forming the oil repellent film, a step of applying an air current to the part of the predetermined area on which the oil repellent solution is supplied so as to peel off an excess part of the oil repellent solution supplied onto the part of the predetermined area, and a step of making a relative movement of the predetermined area in which the oil repellent film is formed, the relative movement being made with respect to the supplying portion by which the oil repellent solution is supplied.

Abstract: A magnetocaloric effect heterostructure having a core layer of a giant magnetocaloric material and an elastically stiff material layer coated on at least one surface of the magnetocaloric material layer. The elastically stiff material layer restricts volume changes of the core layer during application of a magnetic field to the heterostructure. A magnetocaloric effect composite powder including a plurality of core particles of a giant magnetocaloric material. Each of the core particles is encapsulated within a coating of elastically stiff material that restricts volume changes of the core particles during application of a magnetic field thereto. A method for enhancing the magnetocaloric effect within a giant magnetocaloric material including the step of coating a surface of the magnetocaloric material with an elastically stiff material. The elastically stiff material restricts volume changes of the magnetocaloric material during application of a magnetic field thereto.

Abstract: A can filler valve wiper mechanism for use with a can filler machine is disclosed. The can filler machine includes mechanism for moving a can along a predetermined can travel path, and a movable filler valve which moves along a predetermined filler valve travel path above at least a portion of the can travel path. A can wiper mechanism comprises a rotating wiper, which can be a common paint roller. The rotating wiper is disposed at a location between a moving can and a moving can filler valve located above the can so that the wiper engages and collects material located between the valve and can. Preferably, the wiper engages the bottom of the filler valve itself as the valve passes the wiper.

Abstract: A cutoff tool for severing a neck of a difficult-handling fluid material (a fluid material which is highly viscous, highly adhering, highly cohering, and/or shear thickening) includes a rotating whip, for example a string or a wire. The whip may be rotated at a sufficiently high rate, for example by a motor, so as to prevent adherence of the fluid material to the whip, for example by use of centrifugal forces to fling fluid material off of the whip. A system for filling containers includes a cutoff tool operatively coupled with a filling nozzle and a container clamp. A method of filling a container may include clamping the container, inserting a filling nozzle into the container, dispensing fluid material into the container, withdrawing the filling nozzle from the container during and/or after the filling, drawing back fluid material through the filling nozzle so as to thin a neck of fluid material between the filling nozzle and the filled container, and severing the neck, for example by using a cutoff tool.

Abstract: A machine for filling containers with cosmetic products including a support device (3) having a cosmetic powder receiving station and an outlet, a homogenizing and feeding device (1, 2, 20) for depositing cosmetic powder onto the support device at the receiving station, a leveling device (4) for forming the cosmetic powder into a layer having a predetermined height, a tablet forming station, a tablet forming device movably mounted (5) relative to the support device for pressing portions (12) of the layer into tablets of cosmetic product and withdrawing the formed tablets from the layer at the tablet forming station, a discharge station for receiving the tablets in respective tablet containers (14), guides (5) for supporting the tablet forming device for movement between the tablet forming station and the discharge station, a discharge device (11) for ejecting the tablets from the tablet forming device into the respective containers at the discharge station, a collection sump (15) at the outlet of the support

Abstract: The services normally associated with the lubrication oil tank used on aircraft are made dependent of each other by the judicious location of the various service housings, inlet ports and internal passages. The caps of the pressure fill port and overfill port are sequentially removable in order to prevent fill while the overfill port is blocked off. The overfill port and JOAP port are combined and internal valving automatically responds to the type of service called for.

Abstract: A receptacle includes a receiving chamber into which an injection fluid is to be injected. An injection unit includes a syringe having a needle adapted to pierce a diaphragm of the receptacle. The injection unit has a second needle [(28)] that may be advanced through a further diaphragm into a return chamber of the receptacle. The second needle is secured to a sliding pipe coupled to the syringe via a coupling means. Both needles are advanced simultaneously into the receptacle. Then, the syringe is ejected by moving the syringe plunger. The liquid volume displaced from the return chamber reaches the rear barrel chamber via the sliding pipe, the volume of the rear barrel chamber increasing by the amount in which the injection fluid has been ejected, subtracting the volume of the plunger rod. The exchange of liquid is supported by the suction effect of the partial vacuum generated by the lowering of the syringe plunger. The fluid of the injection device is sealed tight against the environment.

Abstract: There is disclosed a plant for pasting battery plates comprising a pasting machine comprising a flat conveyor belt and paste applying means for forcing paste into a grid conveyed on the conveyor past the said paste applying means, grid feeding means, and a transportable hopper and mechanical discharge means for mechanically discharging paste into the inlet to the pasting machine, paste recycling means adapted to mechanically collect paste applied to the conveyor and to convey it back to the inlet to the pasting machine, and a drying oven.
