Abstract: A measuring head (4) according to the invention comprises the combination of a zone lens (26), which is preferably a diffractive lens, with a hemispherical lens (23) or a GRIN lens (33). This represents a concept capable of miniaturization, resulting in very slender measuring heads (4) having a high numeric aperture and, accordingly, leads to the best resolution capacity. Such measuring heads are insensitive to angular errors as concerns the orientation of the measuring head to the surface to be measured or to an oblique positioning of the surface relative to the optical axis of the measuring head.

Abstract: A micrometer screw gauge comprises a divided measuring spindle. The gauge's front part representing the measuring screw is secured in a torque-proof manner in a guide element. The rear section configured as a threaded spindle has the same diameter. In so doing, it is coupled in an axially rigid but rotatable manner to the measuring screw. This measuring spindle may replace a conventional, rigid, continuous measuring spindle of a micrometer screw gauge and, in so doing, results, without substantial design change, in a micrometer screw gauge comprising a non-rotatable measuring spindle.

Abstract: In a point of purchase display having an integral graphic panel metallic supporting frame for an H-frame shelving system, retrofit pliant graphic panels are provided that may be quickly installed and remain firmly secured but may be quickly detached from the supporting frame to change the graphic message. The retrofit graphic panels utilize U-shaped top clips which are positioned to align with and operably engage the upper portions of the supporting frame and pliant magnetic strips attached to the back of the graphic panels to align with and magnetically adhere to lower portions of the metallic supporting frame. In another embodiment, in addition to the U-shaped top clips and pliant magnetic strips used to secure the graphic panels to the metallic supporting frame, leading edge clips are also utilized to secure certain of the graphic panels to product carrying bins of the point of purchase display.

Abstract: A novel lamp socket finding application with a type of increased protection, has a housing part (13) in which a one-piece elastomer sealing sleeve (20) is preferably rotatably held. The sealing sleeve (20) is at its lamp-side end preferably slightly radially compressible, while it is stiffer in the axial direction. As a result, it yields inward when axially pressed by the frustoconical inner side of the housing part (13). The one-piece construction of the sealing sleeve (20) from a single material, on the one hand, ensures a simple manufacture and, on the other hand, prevents a faulty mounting caused by slipped seals or the like.

Drains are provided for both channels.

Abstract: A system for continuously charging containers with a flowable substance including solid material, has a first pipe, a flow sensor for detecting substance flow in the first pipe; a plurality of valved second pipes each communicating with the first pipe and extending into a respective container; a level sensor associated with each second pipe for directly responding to a predetermined height level of the solid material accumulating in each respective container; and a control arrangement connected to the flow sensor, the level sensors and the valves of the second pipes for shutting off the valve of that second pipe through which charging was in progress and simultaneously opening the valve of another second pipe which is associated with an empty, standby container, at the moment when the level sensor associated with the container undergoing charging indicates that the solids reached the "full" level, while, at the same time, the flow sensor continues to indicate substance flow.

Abstract: A redundant power supply/signal conditioner system for a resistance temperature detector includes power supply/signal conditioner modules having first and second output terminals connected to a resistance temperature detector. Diode circuits are connected across the output terminals of each of the power supply/signal conditioner modules to provide an alternate current path when the corresponding power supply/signal conditioner module is removed or is not conductive due to a failure. Each of the power supply/conditioner modules includes a constant current source for supplying a constant current which is slightly different in each of the modules. Each of the modules also includes an overvoltage protection circuit for preventing the voltage output by the constant current source from exceeding a predetermined value and a signal conditioner which outputs a signal based on the temperature detected by the resistance temperature detector.
