A system for moving data between sessions on a workstation having a video display is described. A source session having data in protected and unprotected fields is copied to storage through a clipboard media. Pasting of data from the clipboard into unprotected fields of a destination session is accomplished selectively. Pasting is selectively concluded based upon a comparison of source protected f...

The cleaning device comprises a squeegee (1) formed of a blade of elastic material, inside which are formed suction ducts (5) which open in at least one face of the blade through orifices (7) aligned in parallel with the lowermost edge (8) of the squeegee, close to said edge. The suction ducts (5) are connected with flexible tubes (10) passing through a roller-type pump (11) to wards a collector t...

A Fault Detection and Bandwidth Monitoring Arrangement for a Packet Switching Arrangement The fault detection and bandwidth monitoring arrangement provides a counter in association with each virtual circuit crosspoint. The counters may be provided with a common or individual threshold value which when exceeded causes alarm signals to be generated. The counter arrangement is arranged to record the ...

An inductive coil for heating a rotating roller is embedded in a plastic carrier. To cool the plastic carrier in the region of the coil, a cooling element in the form of a flat cooling chamber through which a fluid cooling medium can flow is provided on the front surface of the plastic carrier facing the roller periphery.

A self-propelled platform car (SPPC) type conveying system for moving a platform car on a running surface along a predetermined path, which comprises a SPPC having at least three steerable wheels disposed respectively at the front and at the back of the SPPC, at least one of the wheels being motor driven, a guide rail disposed below the predetermined path, front and back steering trolleys having s...

The invention relates to a scissor sharpener comprising a grinding element which is passed along the scissor blades between them during sharpening. The blades can be provided with a microscopic transverse toothing if the grinding element is formed by two rolls the rotation of which is prevented when they are passed from the blade point toward the scissor hinge and allowed when they are passed in t...
