An electrical circuit is powered by a power supply. There is a first operating circuit which is always energized with electrical power from the power supply. The first operating circuit is operatively connected to a power reducing device. There is a second operating circuit which can, for example, operate the processing portion of a small appliance, such as an electronic calculator. The second operating circuit receives power from the power supply, but is not energized at all times. That is, the...

A baffle retard the transfer of heat from a mold structure to a chill plate during casting of molten metal. The baffle includes a circular support portion and a plurality of flexible segments which extend from the support portion. Each of the segments is engageable with an irregular side portion of the mold structure. During a casting operation, the chill plate and mold structure are lowered from a furnace chamber. As they are lowered, the baffle is maintained in engagement with an irregular sid...

A method of determining the specific gravity of a fermentable liquor during fermentation is disclosed. Specific gravity is determined from measurements of original gravity, velocity of sound, and temperature.

A method and a device for ultrafiltration during hemodialysis are described in which ultrafiltrate fluid, before removal from the dialysis circuit, is passed through a balancing device, which is also used as ultrafiltrate pump. For this purpose, a controller controls and actuates inlet, outlet, and dialyzer valves, in such a way that a desired amount of ultrafiltrate, corresponding to the filling volume of a balancing chamber or a multiple thereof, is introduced to the discharge through the bala...

A dop for handling a gemstone comprising an elongate shaft having shank and gripper portions located at respective ends thereof, a shaped portion about the shaft defining a plurality of externally sensible features for providing information uniquely identifying the dop and establishing its spatial orientation and that of the gemstone.

A document copier, having a copier operation that includes image editing for inputting data of a production run, which data both (1) specifies special features and (2) defines areas of an original document for treatment by the special features. An interrupt mode interrupts the image editing and the image forming so that a job of higher priority can be processed. The special features specifying data and the area defining data of a production run are stored only for areas which are completely defi...

Apparatus for supporting a door during processing and applying fixtures thereto prior to installing in a doorway comprises a rigid elongated frame including vertical supports at each end thereof and one or more longitudinal members interconnecting the vertical supports, each of such longitudinal members comprising a pair of telescoping tubular members and means for securing the tubular members in any desired relative positions to accommodate doors of different lengths. A pair of lateral door-sup...

Radioiodination of aminoacyl-transfer RNAs with either .sup.125 I or .sup.131 I resulted in the preferential addition of radioiodine to bound tyrosine. The radioiodinated tyrosyl-tRNA was 10-fold purified by chromatography and was found to consist essentially of monoiodo- and diiodo-tRNA in approximately equal isotopic proportions. The radioiodinated tyrosine was readily incorporated into proteins synthesized in broken cell reactions. The specific activity of the iodine-labeled proteins can be m...

A speech recognition device (1) processes speech data (SD) of a dictation and thus establishes recognized text information (ETI) and link information (LI) of the dictation. In a synchronous playback mode of the speech recognition device (1), during the acoustic playback of the dictation a correction device (10) synchronously marks the word of the recognized text information (ETI) which word relates to the speech data (SD) just played back marked by the link information (LI) is marked synchronous...

For avoiding poisoning effects during anesthesia, the quantitative amount of an anesthetic agent degradation product, preferably carbon monoxide CO and/or trifluoromethane CHF.sub.3, in an anesthetic gas mixture is determined. When the determined quantitative amount of the anesthetic agent degradation product in the anesthetic gas mixture exceeds a given threshold, an alarm is provided. This is preferably accomplished by measuring a Raman spectrum of the gas mixture, and determining the quantita...
