Abstract: Abstract A process and apparatus for the control of the path of the grinding tool of an all-around edge qrinding machine supporting a glass pane for movement about a rotational axis.  The grinding tool is positively guided into contact with the edge of the glass pane as controlled by the contour of the glass pane.  A scanning roller, also guided into contact with the edge of the glass pane provides the control heretofore described.  Both the grinding head and scanning roller are movable in a direction toward the rotational axis of the glass pane.  Path signals determined by the scanning roller are stored in a sliding register, and delayed at its output for a period of time required for movement of the glass pane through an angle which corresponds to the rotational angle (.alpha.,.beta.) between the point of contact of the scanning roller and the point of contact of the grinding tool on the edge of the glass pane.  The path signals from the sliding register are used in position controlling the grinding tool.  The scanning roller and the grinding tool each may be disposed on a sled for move-ment in directions colinear with a radius from the axis of rotation of the glass pane.  The scanning roller and the grinding tool each may be disposed at the end of a rocker arm for movement along a circular path.

Abstract: A B S T R A C T      A multi-layered electrophotographic element providing significantly improved properties, and especially so for use as a "permanent" master in transfer photocopying, comprises a conductive support carrying a photoconductive charge generating layer and on top of the photoconductive layer a charge transporting layer containing homogeneously distributed in an insulating binder a charge transporting agent selected from among certain azines which may comprise one or more alkylsubstituents and/or heterocyclic groups with at least one nitrogen atom and/or phenyl or naphthyl groups. The charge transporting layer may also contain to advantage an activator for the charge transporting agent. Particularly effective activators are terephthalal dimalo-nitrile (TDM) and 1,3,7- trinitro-dibenzothiophene-5,5-dioxide (DBTO). The charge transporting layer preferably is applied to a very thin charge generating layer formed on an endless support,and which contains the charge generating compound in molecularly divided form. Photocopying can be carried out with enhanced permanence of the usefulness of the element by charging the element for each copying operation to not more than about 70% of its maximum chargeable surface voltage.

Abstract: ABSTRACT OF THE DISCLOSURE         Carbon in the form of graphite is commonly used in refractories for metallurgical purposes because of its ability to increase resistance to corrosion.  However, if the graphite in the refractory becomes oxidized, it greatly loses this ability.  For this reason, it is very important for a refractory to have good resistance to oxidation, but there are at present no refractories fully satisfactory from the standpoints of re-sistance to oxidation and hot strength.  The present invention is a carbon-containing refractory having excellent resistance to oxidation and hot strength.  These favorable properties are obtained by the addition in the refractory of both boron carbide and metal powder, the powder comprising at least one metal selected from A?, Si, Fe, and Ni.

Abstract: A B S T R A C T            A  device for torsion-proof connection of a number of elements in direct or indirect rolling contact with each  other,  which together  make  a  robot arm or the like, whereby the elements are  held  together  and  actuated   by   force   transmitting actuators,  for  example  cords.  The  object  of  the present invention is to provide a device  with  which  the  individual elements  of  a robot arm can be torsionally locked so that it can bear significant torsional forces without detoriating  the rolling  characteristics of the elements. This object has been achieved by the fact that the elements  pairwise,  with  their rolling  surfaces   turned towards each other, being connected with each other through a torsion  member  which  is  flexible and/or  jointed  in  the rolling direction of the elements and which has a great stiffness across the rolling direction.

Abstract: A probe is provided for testing or treatment of molten metals, alloys etc. with ultrasound. The probe is provided with a cooling means, near to its tip for contacting the melt, so as to be able to provide a steep temperature gradient over the melt contacting end of the tip. The temperature gradient is such that, when the probe is a steel rod of about one inch diameter, the temperature at a point 2 inches from the melt contacting point is at least 700.degree.C lower than the melt temperature. In rods of other materials and other sizes, an equivalent gradient is created, within the limits of the thermal conductivity of the material and the size considerations. This cooling allows for enhanced transmission of ultrasound signals through the metal probe.
