An ink metering method for an inking mechanism of a rotary printing machine having an ink fountain, a doctor roller, a separate electric motor for driving the doctor roller and a low speed of rotation relative to the printing machine, includes the selection of a rate at which the electric motor imparts to the doctor roller discrete angular motions; and selecting by a second selector switch the magnitude of the angular motions. A circuit arrangement for carrying out the method includes a time selection unit which delivers at its output a series of pulses at a desired rate; an increment evaluation unit which receives at its input a number of pulses corresponding to the magnitude of the angular motion performed by the electric motor and compares the momentary number with a preset desired number corresponding to a desired magnitude of the angle of rotation.

Apparatus for blocking the release of a surgical table from engagement with a floor bracket is provided. In a surgical table having a foot lever which actuates a bar to cause the release of connecting means from a tongue of a floor bracket, a vertical pin is provided on the bar. A base plate having a slot therein is provided on the lower portion of the surgical table adjacent to the pin. A blocking plunger of a first pulling solenoid may be extended across the slot to block the movement of the pin to prevent the displacement of the bar and the release of the connecting means from the tongue. The extension of the blocking plunger is caused by the retraction of an extension plunger of a second solenoid, which extension plunger is parallel to but disposed above the blocking plunger and is connected to the blocking plunger by a connecting block. The extension of the blocking plunger causes a cam surface on the connecting block to engage a cam follower to actuate a microswitch which produces a signal indicating the blocking of the pin. The blocking plunger may be retracted from its blocking position by being retracted by the first solenoid to free the pin and allow release of the surgical table from the floor bracket.

In a small PABX with a switching matrix that has electronic crosspoints, integrated selector components comprising multiplexers or demultiplexers in C-MOS technology are used for the switching matrix. By means of individual dialing connection points, which are determined by an appropriate control address supplied by a control computer unit, the individual subscriber lines are to be connected together in internal traffic, and the subscriber lines are to be connected with an exchange line in external traffic. The switching matrix is electrically separated from other operating units by repeating coils in the subscriber lines and in the exchange lines. Central units (tone receiver, tone generator) are connected through free dialing connection points of the multiplexers.

A RAM memory cell in double polysilicon technology having improved packing density is attained by insulating neighboring active memory regions under a first polysilicon plane by ion implantation to increase the substrate doping of the surface of the semiconductor body whereby field shield insulation regions are generated by a transistor in the off-state and the memory regions are rendered self-conducting by the ion implantation so that with a voltage at the polysilicon-1-electrode of 0 volts, the full operating voltage can be written into the memory capacitor.

Compounds obtained by the addition of unsaturated esters to the >NH group of compounds of formula II ##STR1## are useful as light stabilizers for polymeric materials, particularly for thermoplastic polymers and automotive finishes. Preferred compounds are those in which R, R.sub.1 and R.sub.2 are all hydrogen and R.sub.3 and R.sub.4 together with the carbon atom to which they are attached form a cyclododecylidene ring.

Various embodiments for hit testing of visual objects are described herein. Data of visual objects is generated in a two-dimensional clip space. The data of visual objects includes two-dimensional projections of the visual objects. Cursor coordinates are transformed into the clip space and bounding box calculations are performed using the transformed cursor coordinates and the generated data. Hit testing is performed when there is a hit on a bounding box of at least one of the visual objects in the clip space. The hit testing is performed in a three-dimensional space. A result is then presented on a user interface based on the hit testing.

A high-pressure cleaning appliance with a high-pressure pump is provided. The pump has at least one pump chamber connected to a suction line and a pressure line. The pressure line is in flow connection with the suction line via a return flow line. A relief valve with a through-channel extending from a valve inlet to a first valve outlet is arranged in the return flow line. A valve element which in a closed position bears against a valve seat is held for movement in the through-channel. At least one outlet channel, which opens into a second valve outlet, branches off from the through-channel. The valve element is surrounded by a sealing ring which seals off an inlet area of the through-channel adjacent to the valve inlet from an outlet area of the through-channel adjacent to the first valve outlet.

A load balancing method and system for identifying an input/output (I/O) network path from a set off I/O network paths is provided by the invention. The set off I/O network paths connect a host system via a network to a storage subsystem. The host system comprises at least one host bus adapter (HBA) and the storage subsystem comprises at least one I/O device and the network comprises at least one network device. Each of the HBA, the I/O device and the network device comprise at least one I/O port. For each I/O port of each HBA, an HBA port limit is determined. Additionally the set of I/O network paths which connect the I/O port of each of the HBA via the I/O ports of the network device to the I/O port of the I/O device is identified. Then a fabric utilization limit is determined for each I/O network path and a HBA port utilization is determined for each I/O port of the at least one HBA. All network paths are discarded for which the HBA port utilization is greater than the HBA port limit. For each of the remaining paths a network path distance is determined. All I/O network paths for which the network path distance is greater than the path distance limit are discarded. Then for each of the remaining paths a fabric utilization is determined. All I/O network paths for which the fabric utilization is greater than the fabric utilization limit are discarded and the I/O network path is determined from the remaining network paths.
