Abstract: ABSTRACT OF THE DISCLOSURE          A hand held power tool, particularly of the type of a dental handpiece  or the like is provided with power shut off means disposed directly within the handle.  The shut-off means is mechanically connected with a suspension means for suspending the hand piece or the like power tool such that the weight of the tool shuts off power supply to the tool.  In a particularly preferred embodiment, a dental handpiece is disclosed wherein the suspension means is a magnet, whereby the handpiece can be suspended on any ferromagnetic surface without having to reach to a suspension fork which, in the known devices, is itself associated with a   shut-off valve.  The basic idea of the invention has broad application in many different fields of technology.          The advance in the art, best represented by the dental handpiece, is an added convenience of temporarily suspending the handpiece at a place remote from the suspension fork which often is inconvenient to reach, while achieving the power shut-off without having to manipulate any further control means.

Abstract: JOB RECOVERY METHOD and SYSTEM              Abstract of the Disclosure Job recovery method and system for generating complete sets of copies and providing billing information with respect thereto.  Job recovery is automatically effected after a jam occurs with respect to copy sheets by maintaining counts of sheets reaching the exit pocket and retained in the duplex tray for determining therefrom images lost due to the jam and responsive thereto generating replacement copies. Counts are also maintained for determining when copying of each set is complete and for billing purposes with the count for billing purposes reflecting only delivered copies with no additions being made for replacement copies generated due to lost images.  For effecting job recovery due to jams occurring during imaging of duplex copies, replacement sheets are generated immediately after each jam to replace those sheets lost due to the jam by determining the number of pages to be printed, dividing this number by two, and subtracting therefrom the count of sheets in the duplex tray and in the exit pocket, with this determination being then used to control generation of first side images on sheets needed for replacement purposes with said sheets being then conveyed to the duplex tray so that the resulting duplex copy generation is complete when reaching the exit pocket.

Abstract: METHOD OF PREPARATIVE, KOHLRAUSCH-REGULATED      ELECTROPHORESIS USING POLYETHYLENE GLYCOL         DERIVATIZED TRAILING IONS            Abstract of the Disclosure An improved method of Kohlrausch-regu-lated electrophoresis (isotachophoresis) is dis-closed for the preparative separation of respec-tive macromolecular components such as proteins in a crude sample.  The preferred method involves use of a substantially linear, polyethylene glycol derivatized trailing ion having a relatively high mass to charge ratio and a low mobility which is substantially independent of pH changes over a relatively broad pH range.  The most preferred trailing ion is a polyethylene glycol dicarboxylic acid having a molecular weight of about 6,000 -7,500, a pKa value of about 3.7, and a fully ionized mobility of about -1.3 x 10-5 cm.2/volt/ sec.  The method hereof permits large scale pro-tein separations and subsequent collection of purified protein fractions over a wide range of pH conditions and without interfering reactions between the proteins and trailing ion.
