Abstract: MULTIPLE SPEED DRIVE SYSTEM        Abstract of the Disclosure An oil shear clutch-brake unit includes a housing rotatably support-ing an input shaft and an output shaft in axial alignment, and the hous-ing encloses a set of interfitting clutch plates and discs for coupling the input shaft to the output shaft and a set of interfitting brake plates and discs for braking the output shaft.  A non-rotating piston is also enclosed within the housing and is fluid actuated in both direc-tions from a spring biased neutral position for either clamping the clutch plates and discs or clamping the brake plates and discs.  A cool-ing and lubricating oil is circulated within the housing and between the plates and discs, and the pressure of the fluid for actuating the piston is adjustable for selecting the torque transmitted through the clutch and brake.  The output shaft of the clutch-brake unit drives the shaft of a high speed electric motor, and the input shaft is coupled to the output shaft of a slow speed motor-gear reducer unit which mounts directly on the housing of the clutch-brake unit.  The assembly of the clutch-brake unit may be arranged in-line with the high speed motor with a direct coupling of the shafts, or the assembly may be located above the high speed motor with a belt drive coupling of the shafts.

Abstract: MOBILE CABLE WINCH     ABSTRACT OF THE DISCLOSURE          In a portable cable winch which is adapted to haul in a load, the smooth shell of a motor-driven cable drum is provided with at least one conical surface having an angle of inclination corresponding to the angle of friction be-tween the load-bearing cable and the cable drum.  By means of a clamping disk driven in synchronism with the cable drum, the load-bearing cable which is pulled away from the smaller-diameter end portion of the conical surface and which is deflected by the clamping disk towards a cable storing means the cable has  applied thereto a clamping force which, for the purpose of hauling in a load, acts in a rearward direction on the cable to be hauled in as a pulling force transmitted by the conical surface.  In an embodiment in which the shell of the cable drum is subdivided into two conical surfaces having identical angles of inclination but being disposed on the axis of the cable drum in such a way as to extend into opposite directions, it is possible also to employ the cable winch as a hoisting gear for raising and lowering loads with the load-bearing cable, upon the direction of rotation of the cable drum being alternatingly guided onto the one or the other of the two conical surfaces such that the cable forms a plurality of turns wrapping the respective conical surface.  In both cases the cable drum is operated as a pull-through drum so as to prevent the individual turns of the cable from being superimposed, with the result that it is possible to drive the drum independently of the length of the cable by applying a constant invariable torque thereto.

Abstract: ABSTRACT OF THE DISCLOSURE              There is disclosed an ice-skate blade in which the portion of the ice-engaging surface of the blade which is inter-mediate the sharpened side edges of the blade, is polished to a mirror-finish, in order to decrease the friction between the blade and the ice.  To polish this intermediate surface with conventional polishing compounds, a felt disc is used.  A width-reducing device is used to taper the marginal portion of the disc to the width required to sharpen only the central surface of the blade and not the side edges.  This device comprises an assembly of blocks, or braces, forming a V-shape slot with the inclined surfaces lined with abrasive material to receive the marginal portion of the felt disc which is reduced in width while rotated in said slot.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention provides a process for stabilizing a population of a mutant microorganism in a bioconversion system whereby growth of revertant cells is suppressed.         The process involves limiting a nutrient which is essential for cell growth so that the cells selectively grow on a growth carbon source rather than on a non-growth carbon source which is present.  The revertant cells being suppressed have a similar ability as the parent strain of the mutant microorganism to grow on the non-growth carbon source in the bioconversion system.         The non-growth carbon source in the bioconversion system is metabolized to an extracellular accumulating quantity of a desired metabolite, e.g., toluene is converted to muconic acid.

Abstract: Abstract In a method of operating a vapor burner, liquid fuel is fed to an evaporating chamber, is there heated up to vaporisation and then delivered substantially as a gas to a combustion chamber where it is mixed with at least the predominant part of the air of combustion.  In a clean-sing phase taking place during interruption of fuel supply, the evaporating chamber is heated to a cleansing temperature at which deposits on the chamber wall burn to ash.  The ash is then blown out into the combustion chamber, e.g. by cleansing air supplied during the cleansing phase. The evaporating chamber is substantially formed by an evaporating tube (2) extending centrally to the passage system (10).  The cross-section of the outlet aperture (5) is at least 5% of the internal cross-section of the evaporating tube (2). A control device (28) comprises a programme circuit (60) which is so designed that, in the presence of i blocking signal (R) at the first outlet (61) and on the occurrence of a cleansing signal (S), the second outlet (62) delivers a switching signal (T)  by reason of which the heating apparatus (2) is supplied with electric energy sufficient for burning deposits in the evaporating chamber (1).
