Abstract: A clamp includes a fixed gripper, a moveable gripper, a driven member, an actuator, and first and second tracks. The driven member is configured to slide within the first and second tracks. The moveable gripper is operatively coupled to the driven member. The actuator is configured to move the driven member towards a first position to thereby move the moveable gripper towards the fixed gripper. The actuator is further configured to move the driven member towards a second position to thereby move the moveable gripper away from the fixed gripper.

Abstract: A method for modifying a surface by generating nanotubes at one or more selected sites on the surface, the surface including a first metal. The method includes the steps of positioning at least one cathode and at least one anode relative to the surface in an electrolyte solution including a fluoride salt of a second metal, and applying a voltage between the at least one anode and the at least one cathode sufficient to generate nanotubes at one or more selected sites on the surface and to inhibit nanotube formation at one or more of the other selected sites, wherein the nanotubes include the first metal and the second metal.

Abstract: A method of workload placement among servers includes receipt of a workload request. The method also includes selection of a group of servers from a set of servers capable of performing the requested workload. In addition, server workload indexes, which are ratios of temperature rises due to re-circulation load for the servers in the group of servers to temperature rises due to re-circulation load for the set of servers, of the servers in the group of servers are calculated. Moreover, the workload is placed on one or more of the servers in the group of servers based upon the server workload indexes of the servers in the group of servers.

Abstract: An error rate monitor having means to detect errors in a data stream and a counter for counting the quantity of data or elapsed time between two consecutive errors. The monitor may also caculate running totals of the number of counts falling within each of a plurality of bands of count value. A display shows the running totals as bars on a bar graph, together with two pointers indicating the counted data or time since the previous error and the counted data or time since beginning operation.

Abstract: A light meter comprising: a light sensitive charge storage array having at least one charge storage cell, and reading circuit means connected to said array for generating a light reading from charge stored in said array, said light reading being indicative of the quantity of light incident on said array; wherein said reading circuit means collects charge from said array and compares said collected charge to a threshold to generate said light reading.

Abstract: In a double chamber container, the inner chamber is formed by a tubular body of an elastic rubbery material stretched in order to expel a pressurized substance against its own elasticity. To obtain a precise stretching ratio of the tubular body and to empty it as well as possible, the tubular body converges uniformly and its walls have a uniform thickness, even in their bottom part. To attach the tubular body to the container, a collar which acts also as a seal is formed on the thereon. A process for producing the tubular formation includes bringing an elastomeric material into the flowable condition and coating it over a mandrel, and applying a cooling medium detachable from the mandrel over the mandrel initially and/or applying a treatment medium detachable from the mandrel over the latter subsequently, for the controlled alteration of the surface on the mandrel side of the elastomeric material.

Abstract: An arrangement for cutting thin-walled reinforced closed bands of rubber into rectangular belts having the same width is suggested wherein the closed band is tensioned between two rollers. By deflecting one of the two rollers, the closed band experiences a force component parallel to the roller fixed in position which drives the closed band against a stop. With this arrangement of the stop on the end facing toward the cutting device even thin-walled closed bands can be cut into rectangular belts with a uniformity in width not attained previously.

Abstract: In a double chamber container, the inner chamber is formed by a tubular body in an elastic rubbery material stretched in order to expel a pressurized substance against its own elasticity. To obtain a precise stretching ratio of the hose (1) and to empty it as well as possible, the hose converges uniformly and its walls have a uniform thickness, even in their bottom part (9). To attach the hose (1) to the container, a collar (11) which acts also as a seal is formed on the hose.

Abstract: In order to fill a container having a check valve with a spontaneously foaming filling material, the latter is introduced through the check valve already mounted at the container. In a piston arrangement as the filling device, filling material to be filled in is sucked into a mixing chamber (65) by means of a metering piston (60), foam gas is injected through the piston rod (58) of this piston, filling material and gas are mixed by means of a mixing piston (56), then forced by means of the metering piston (60) through the check valve into the container. This prevents frothing of the filling material, intermixed with foam gas, at any point in time between mixing and filling. During mixing, slight foaming is desirable in order to increase the absorption capacity for the foam gas.

Abstract: A control system is disclosed for use with pressure-driven loads, such as reversible motors. The system allows the loads to be driven at varying speeds and also allows the loads to be reversed. However, the system is so designed that an operator cannot subject the loads to pressure shock caused by abrupt changes in pressure by adjusting the system too rapidly. The system disclosed is suitable for use with either hydraulic or pneumatic loads.

Abstract: A dialysis module for use with a variety of single pass or single pass-recirculating artificial kidney dialyzers as desired. The apparatus has quick disconnects to allow attachment of a single pass kidney dialyzer or shunt tube so that a single housing can be used to provide two entirely different modes of operation as selected. A clear canister forms a part of the dialysis flow path in both modes of operation to enable rapid detection of blood leaks in either mode of operation.

Abstract: A dialysis module for use with a variety of single pass or single pass-recirculating artificial kidney dialyzers as desired. The apparatus has quick disconnects to allow attachment of a single pass kidney dialyzer or blocking off of a portion of a fluid conduit when a coil dialyzer is used so that a single housing can be used to provide two entirely different modes of operation as selected. A clear canister preferably forms a part of the dialysis flow path in both modes of operation to enable rapid detection of blood leaks in either mode of operation. An aspirator is associated with a recirculating pump to provide negative pressure to dialysate in the flow path when a single pass dialyzer is used while only the recirculating pump is necessary during single pass-recirculating dialysis.

Abstract: Dual-chamber pressurized dispensers for a variety of products. A flexible inner container defines one chamber in which the product to be dispensed is contained, the inner container being connected at one end to a dispensing valve. A rigid outer container encloses the flexible inner container and therebetween defines another chamber in which a pressurizing propellant is contained. Each inner container is designed to achieve high expulsion efficiency, with an upper portion having a lipped aperture in which the dispensing valve is received and a lower portion having longitudinal stiffening ribs.
