Title: Ceramic resistor body - for resistor without end caps
Inventor: ENGL ALFRED DIPL CHEM DR
IPC: B28B3/20
Filed: 1971-11-12
Abstract: The resistor terminations are axial wires forced into blind holes on the end faces of the ceramic body. To make the bodies, first of all a core extrusion of alternate fired ceramic material and suitable binder sections is made and then passed through a secod extruder in which it is coated with unfired ceramic. When fired the binder is burnt off but the ceramic outer layer is sintered to the ceramic sections of the core. A solid rod is thus produced with cylindrical cavities at regular intervals, and is cut, into separate bodies, in the centre of these cavities.

Title: Reclaiming red-luminescent materials in colour TV tube mfr - bromine added to suspension contg. citric acid decomposes zinc sulphide
Inventor: BOLZ BRUNO
IPC: C09K11/01
Filed: 1973-05-09
Abstract: The recovery of europium-activated red luminescent materials based on rare-earth metal oxides or oxysulphides (e.g. Y2O3:Eu, Y2O2S:Eu) from a cold aq. suspension which also contains ZnS or Zn-Cd-S luminescent materials, binder, and impurities. A complex-forming acid (citric or acetic) is added to the suspension to give pH of 2-3. Bromine (or Cl or I) is then added dropwise which instantly decomposes the sulphides and impurities; the Br addn. is stopped when examination under a microscope shows the red-luminescent material to be free of impurities. The mixt. is then filtered, washed with cold water followed by isopropyl alcohol which removes most of the sulphur, and dried. The material is next heated for passivation and to remove the remaining sulphur, using a temp. of 400 degrees C for the oxysulphide and 900 degrees C. for the oxide. This new process is much simpler than existing methods of reclamation.

Title: Liquid manure stirring mechanism - has stirring blades at bottom of motor driven shaft supported in joints
Inventor: LEDERLE HANS
IPC: B01F7/00
Filed: 1974-04-27
Abstract: Liquid manure stirring mechanism has a motor driven shaft that can be raised or lowered. It has stirring blades at the bottom end which can be moved on joints, passing normally to the axis or rotation, to vary the diameter of the stirring tools. The stirring blades are supported in the joints so that they can move freely. They set themselves towards the outside under the influence of the forces resulting during rotation, but on smaller rotational forces they move into an axially parallel position. Specifically the blades move into the axially parallel position and their own weight and centrifugal force forces them outwards.

Title: Steam heater with helical coils - having greater flow area for condens. zone than desuperheating or condensate cooling
Inventor: ABADZIC ESREF DR ING
IPC: F28F9/00
Filed: 1974-07-10
Abstract: Heater using steam as the heating medium consists of a shell enclosing a series of helical coils mounted around a central axis, the liquid to be heated flowing through teh coils. The shell space into which the steam is passed is divided into several zones, one for taking the superheat out of the steam, one for the condensation and one for subcooling the condensate. An annular baffle surrounds the upper section of the coils while there is an annular gap around the section where condensation occurs between the coils and the vessel wall. In the lower subcooling section there is also a baffle. For use with ht. exchangers where fluids are being heated. In the desuperheating zone the ht. transfer is improved by a higher flow velocity over the coils. The effectiveness is in part measured by the pressure drop. Thus a pressure drop in this zone is of advantage. In the condensation zone, the ht. transfer mechanism is different and pressure drop is no advantage. In the condensate sub-colling zone, ht. transfer is again proportional to flow and a pressure drop is an advantage. The heater described combines these features.
