Abstract: ABSTRACT OF THE DISCLOSURE            A current transformer encapsulated in an injection molded layer of insulating material.  The current transformer includes a secondary winding which is disposed around a winding spool having side flanges thereon.  Permanent spacers extend across the length of the winding spool and rest on the side flanges such that the permanent spacers are spaced from the secondary winding.  A primary winding is wound around the spacers so as to be spaced from the second-ary winding before the encapsulating material is injection molded around the magnetic core and windings and into the space between the primary and secondary windings.  The winding spool and permanent spacers are formed of a material which softens within the processing temperature range of the encapsulating material to form an amalgamation without a distinct interface between the encapsulating material and the winding spool and spacers.  In another embodiment, a "through-type" current transformer has a toroidal-shaped magnetic core enclosed in a rigid sheath of solid material.          A tubular member is disposed within the central opening of the magnetic core and secondary winding and is formed of a material which softens in the processing temperature range of the encapsulating material to form an amalgamation without distinct interface therebetween such that a fluid-type seal is formed between the tubular member and the encapsulating material.

Abstract: ABSTRACT OF THE DISCLOSURE A device is disclosed for installing long quartz tubes in apparatus for concentrating mineral acids.  The resulting apparatus is particularly usefulfor concentrating and purifying sulphuric acid.  The novel installation means includes a double-walled fire-resistant tube unit in which the quartz tube may be placed with play between it and the inner wall on the tube unit.  The space between the double walls of the tube unit form an outer flow channel for heatinggases.  The space between the inner wall of the tube unit and the outer wall of the quartz tube form an inner flow channel, also intended for the passage and heating of gases.  These flow channels are connected with each other via holes in the inner wall of the tube unit adjacent the lower end thereof.  It will be seen that the outer flow channel provides for a flow direction opposite to that of the inner flow channel.  The installed quartz tube, at its lower end, rests with the major portion of its weight upon seals by means of a shoulder surface arranged on the quartz tube.  The upper end of the quartz tube is transversely fixed by means of a fastening unit.

Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus and process for forming molded articles from particulate plastic material.  A hollow heat-conductive male mold is surrounded with particulate plastic material.  Heat is applied to the interior of the mold until the temperature of the outer surface is above the fusion temperature and below the melting temperature of the particulate plastic material.  This temperature is maintained until an article of desired thickness is formed.  Thereafter, loose particulate material is removed from the outer surface of the molded article and heat is again applied to the interior of the mold so as to cause the outer surface of the molded article to become smoother. Finally, the article and mold are cooled and the article is removed from the mold.

Granted: 1982-08-03
Abstract: ABSTRACT OF THE DISCLOSURE         The rpm of a rotary dresser wheel is maintained in a fixed ratio to the rpm of a grinding wheel.  The rpm of the grinding wheel is increased to maintain the surface speed of the grinding wheel constant as the grinding wheel wears due to use.  This is achieved by having a variable speed dressing wheel motor for driving the rotary dressing wheel.  The diameter of the grinding wheel is sensed and a grinding wheel speed control increases the speed of the grinding wheel as the grinding wheel becomes worn.  The speed of the dressing wheel is also increased to maintain the two wheel speeds in a constant ratio.
