Abstract:
The present invention relates to novel triazene compounds, to a process for their preparation, to pharmaceutical compositions comprising them, and to the use thereof in the treatment of cancer diseases in humans. The novel triazene compounds are distinguished, as compared with the known triazene compounds, by improved activity while at the same time having reduced toxicity, that is to say by fewer side-effects.
Abstract:
The present invention provides a method and apparatus for determining the functional status of an electromagnetic valve having a solenoid and plunger including determining the electromechanical switching time of a valve based on characteristics of an electrical characteristic responsive to the solenoid; comparing the valve electromechanical switching time to a predetermined value; and generating a valve status signal dependant on the results of the comparison.
Abstract:
A circuit board, which includes one or more sensors, is integrated in a fluid control device, such as a valve manifold and a base plate. The fluid control device selectively directs a fluid used to control pneumatic or hydraulic equipment. The sensors are used to measure physical characteristics of the fluid, such as flow rate, pressure, and temperature. A flow sensor includes a paddle and a support member. The paddle is disposed at least partially in an orifice and is displaced in response to fluid flow. The support member positions the paddle in the orifice and includes a plurality of strain gauges. The strain gauges are disposed on only one side of the support member and are mechanically stressed in response to the paddle being displaced by the fluid flow.
Abstract:
A method and apparatus for determining the service life of a cyclic system the method including the steps of determining at least one characteristic of the system to determine a characteristic value and determining a cycle time of the system. The at least characteristic value is applied to an algorithm in which the characterisitic value is integrated to determine a diagnostic value, and comparing the diagnostic value to a predetermined value to determine the performance status of the system. The apparatus including a sensor for determining a system characteristic and a calculating unit operatively connected to the sensor. The calculating unit including circuitry for performing a mathematical integration on the system characteristic to determine a diagnostic value and comparing the diagnostic valve to a predetermined value to determine the performance status of the system. A notification device operatively connected to the calculating unit for indicating the operational status of the system.
Abstract:
A stackable valve manifold arrangement including a first valve manifold adapted to operatively receive a plurality of valves. The first valve manifold having an upper surface. A second valve manifold is provided which is adapted to operatively receive a plurality of valves. The second valve manifold has a lower surface that is in opposed relationship to the upper surface of the first valve manifold, and the second valve manifold is in fluid communication with the first manifold. The first and second manifolds may each be joined to a circuit board forming a module. The modules are vertically stackable and operatively connected to each other to form a system.
