Abstract: A progressive distributor for lubricant includes a housing block. The housing block includes a lubricant inlet bore, via which receives lubricant, and a plurality of lubricant outlets, via which a metered amount of lubricant is dispensable. A plurality of metering pistons are provided in the housing block for the dispensing of the metered amount of lubricant. The metering pistons are received in associated piston bores. Each piston bore is associated with two lubricant outlets. Each metering piston is displaceable in the piston bore and is configured to alternatingly dispense the metered amount of lubricant to the one or the other lubricant outlet. The piston bores are fluidically connected to the lubricant-inlet bore and to each other via connecting bores to transfer lubricant to the other piston bores. The piston bore includes a first region configured to receive the metering piston and a second region configured as the lubricant outlet.

Abstract: Disclosed is a system for quality assurance of high dose rate radiation therapy. The system includes a radiation delivery system configured to deliver high dose rate radiation therapy, with the radiation delivery system including a radiation source and a collimating system. The system also includes a radiation detection system having a diode to measure high dose rate radiation from the radiation source, an operational amplifier to transform the output of the diode to a measurable voltage, and a voltage source configured to apply a reverse bias to a component of the radiation detection system.

Abstract: A connecting arrangement for connecting a high-pressure hose to a connector. The arrangement features a hollow hose nipple that can be at least sectionally inserted into the hose. A screw sleeve that sectionally encompasses the high-pressure hose can be arranged on the hose nipple. The hose nipple is fluidically connected to the connector and can be connected to the connector by a union nut.

Abstract: A distributor element, in particular a feed distributor, is provided for the metering of lubricants for lubricating installations. The element includes a valve piston featuring a bore. The valve piston moves under the pressure of a lubricant operating at a lubricant inlet against the force of a first return spring from a starting position in which the bore releases a connection between a dispensing chamber and a metering chamber via a connecting passage, to a metering position in which the valve piston releases a passage from the lubricant inlet to the connecting passage and therefore to the metering chamber. Furthermore, the distributor element features a dispensing piston which under the effect of a lubricant entering the metering chamber moves against the force of a second return spring from a starting position and thereby pushes the lubricant volume present in the dispensing chamber between the valve piston and the dispensing piston into a lubricant outlet.

Abstract: The invention relates to a feeding lubricating device comprising a lubricant reservoir (1), a lubricant pump (2) which is driven by a driving motor (16) and is provided with at least one pump element (3) for conveying lubricant to at least one lubrication point, especially at least one feeding distributor (5), via a lubricant conduit (4), a driving member such as a drive shaft, and optional means that are fitted with an eccentric attachment for generating at least one pump stroke of the at least one pump element (3). A pressure relief unit (8) which can also be actuated via the driving member blocks a backflow pipe (4) located between the lubricant conduit (4) and the lubricant reservoir (1) in a pressure phase while unblocking the same in a subsequent relief phase.

Abstract: In apparatus for the treatment of tumors, comprising at least one generator having a power source, and at least two electrode needles for conducting current into, or out of, a tumor, a control arrangement is provided for limiting the current flowing through each electrode to a maximum value.

Abstract: The invention relates to a storage reservoir for receiving grease or a like lubricant for a lubricant pump with a, for example, cylindrical side wall and a cover wall closing off a reservoir interior space at a top of the side wall. A pressure compensation device is disposed such that the reservoir interior space is flow-connected with a reservoir exterior space via an air-permeable but water-impermeable membrane.

Abstract: A device for the continuous change of the flow rate of a viscous medium e.g. hydraulic oils or lubricating greases with e.g. a conical throttle insert (1) with a smooth surface and axially movable in a conical bore (3) of a housing (4) in such a manner that different gap widths and/or lengths between throttle insert (1) and housing (4) connect a housing inlet (5) with a housing outlet (6) for the medium. Alternatively, the device may include circular cylindrical throttle insert (1) having a circumferential spiral groove (2) and being axially movable in a circular cylindrical bore (3) of a housing (4) in such a manner that different lengths of the circumferential groove (2) connect a housing inlet (5) with a housing outlet (6) for the medium being metered.
