A display apparatus for tape running positions is provided with a first pulse generator (36) for generating m first pulses for each revolution of a supply reel (12) in a tape transport, a second pulse generator (38) for generating n second pulses for each revolution of a take-up reel (14), and a counter (44 to 48) for counting the number of the first pulses during one period of the second pulse. The ratio of count value change in the counter for a time period from the start to the end of the tap...

In a toaster having a housing, a bread-supporting carriage movably mounted in the housing for movement between a toasting position, a temperature-maintaining position, a rest position and a supplementary raised position, and a spring coupled with the carriage to apply a force which urges the carriage in a direction from the toasting position toward the supplementary raised position, a manually operable control element is operatively associated with the carriage and is movable to a selected one o...

An air mattress includes a plurality of inflatable sacs juxtapositionally connected together in a mattress envelope; an air pump for inflating or deflating the sacs for cushioning a patient ridden thereon; a leg bending device consisting of a plurality of inflatable sacs transversely juxtapositioned at a leg section of the mattress envelope and formed as arcuate shape when inflated for cushioning a patient's bending leg; a body turning device consisting of a plurality of inflatable sacs longitud...

An automated assembly line is operated and controlled by a computer system. When one or more work stations are inherently "unsafe" to the workpieces which enter them if such workpieces remain at the unsafe work stations for an extended length of time, the computer is operated to prevent a workpiece from entering such "unsafe" work stations, until the closest "safe" downstream work stations are vacant.

The present invention has for its object a discharge gate for a container holding liquid metal, comprising two refractory members which are in face-to-face contact and are slidable one with respect to the other to open and close the gate, each of the members having a central aperture, which apertures are in register when the gate is open, and the gate being arranged such that the members can be moved with respect to one another in two, opposite directions away from the open position, for closing...

A display apparatus for tape running positions is provided with a first pulse generator (36) for generating m first pulses for each revolution of a supply reel (12) in a tape transport system, a second pulse generator (38) for generating n second pulses for each revolution of a take-up reel (14), counter (48, 58) for counting the number of the first pulses during one period of the second pulse, and means (50, 64) for providing preset data to make zero a count value in the counter at the initial ...

A UHF tuner having 70 detent positions with fine tuning capability at all locations. Coarse tuning is accomplished via a toothed, detented disk and a spirally-extending rim having a follower lever operable therewith. The rim has an oblique flank and axial movement of the rim secures fine tuning.

A pile fabric with a woven substrate and a pile which is tied into the substrate at points is provided in the region of the pile-free positions with additional threads of decorative yarn which give the material an appearance which is unknown and untypical for pile fabrics.

A turntable having a plurality of sections containing information cards is provided with control means for accurately stopping the turntable at selected positions to permit retrieval of a desired card. The control means comprises an arrangement of cams, cam-operated switches, and a photoelectric circuit including a light-interrupting disc continuously driven in synchronism with the rotation of the turntable.

A current detector can be fixed in an upright position or in a flat position on top of the surface of a support. The detector includes a housing which is provided with a first series of passages for fixing screws, whereby the axes thereof are perpendicular to a large surface of the housing for fixation on top of the surface of a support. The housing is provided with a second set of passages for fixing screws, whereby the axes thereof are perpendicular to those of the first set of passages for th...
