Abstract: In an engine exhaust catalyst warm-up control, ignition timing is delayed from normal first to raise the catalyst temperature, and then a fuel injection amount is dithered to increase and decrease alternately from a normal amount until the catalyst temperature reaches the catalyst activation completion temperature. In place of the ignition delay control, afterburning control may be employed in which fuel cut for a cylinder and fuel increase for the other cylinders are executed. Further, the catalyst warm-up control may be performed by controlling a supercharging operation and an exhaust gas recirculation operation cooperatively.

Abstract: The drive includes a reversible variable output pump (1), which supplies a hydraulic working machine (6) and is driven by an asynchronous motor (2). The working machine is intermittently hydraulically pressurized. During these times the asynchronous motor can be switched off since the subsequent start-up process, which causes a high current consumption in the case of asynchronous motors, is effected by the variable output pump. Before the beginning of the start-up process the variable output pump is preset to the maximum negative discharge rate by its proportional valve (10) being acted on by a control pressure. The volume pressurized in the working machine is then applied to the output side of the variable output pump. The asynchronous motor is connected to the current supply network after reaching a minimum speed.

Abstract: A pulse tube refrigerator according to the present invention is capable of performing cryogenic operation sufficiently. The cryostat includes regenerators and pulse tubes. Each regenerator has a cold stage at an upper end thereof. Each pulse tube has a low-temperature end portion at a lower end thereof and a high-temperature end portion thereof, the low-temperature end portion being located lower than the cold stage. The cold stage and the low-temperature end portion are connected to each other through a line whose cubic volume is substantially negligible in comparison with that of the pulse tube. Since the pulse tube has working gas of relatively high density in an upper portion thereof and working gas of relatively low density in a lower portion thereof, there is no convection of working gas induced by the gravity. Thus, the cryostat performs cryogenic operation sufficiently without being adversely affected.

Abstract: A portable, potable-water generator for producing high-purity liquid water by condensation of dew from ambient air is described. The generator employs filtration subsystems to remove particulates and aerosols from the incoming air. An enclosed heat absorber cools the filtered air below its dew point and collects droplets of condensate into a closed system.

Abstract: An improved dry ice pelletizer and method for significantly increased pellet production. The improvement consists of multiple injection ports used for the timed introduction of liquid carbon dioxide into a dry ice extrusion cylinder so that the cylinder can be more completely filled with carbon dioxide snow before extrusion takes place. Part of the improvement stems from the use of a solid mass of carbon dioxide, called a puck, which is chamfered and serves to capture carbon dioxide vapor and snow within the compression cylinder. The resulting improvement in carbon dioxide pellet output is roughly 400% over that achieved by conventional methods. The inventive improvement may also be installed as a retrofit to conventional dry ice pellet extrusion machines.

Abstract: A padlock concept consisting of a novel shackle comprised of two tapered shackle elements arranged so that they overlay each other to enclose and opening sufficient to accept the staple of a hasp or attachment device. The shackle elements are connected at one end and when unlocked and unlatched are free to move apart, in a motion causing the two shackle elements to separate, providing a clearance between them, at the unconnected end.
