Title: Even filling mechanism for round upright hopper - has impeller rings of different diameters fixed to shaft at intervals
Inventor: HOLIGHAUS ARMIN
IPC: B65G69/04
Filed: 1977-01-27
Abstract: The mechanism fills round upright hoppers evenly with material in bulk, the material being delivered via impeller plates rotating on a vertical axis. The plates (ST) are rings of different diameters rigidly fixed at set intervals from each other in the vertical direction on a common shaft. The particles of material falling over the plate edges describe different parabolae determined by gravity and centrifugal force, thus filling the hopper (1) evenly. The rings can have horizontal surfaces, their dias. and widths decreasing towards the bottom. Their discharge edges lie inside a cone whose base is formed by the largest dia. ring, adjacent to the inlet.

Title: Ion implantation doping of semiconductor - for diode, transistor or solar cell prodn. using simultaneous doping at front and back
Inventor: RYSSEL HEINER DR ING
IPC: H01L31/18
Filed: 1978-08-10
Abstract: In a semiconductor doping process by ion implantation, several implantation processes are carried out simultaneously pref. >=1 on the front and >=1 on the back. Specifically a diode with a highly doped back contact is produced by implantation of ions of a pentavalent element into the front and a trivalent element into the back of a p-Si semiconductor or of a hexavalent element into the front and a divalent element into the back of p-GaAs. At least 2 different types of ions can be implanted simultaneously on the same side, e.g.-ions of 2 pentavalent elements into the front of p-Si or 2 trivalent elements into the front of n-Si. Process is used specifically for the mfr. of a pn-junction (diode) or transistor and esp. solar cells. Complete semiconductor structures can be doped quickly and economically in a single stage.

Title: Controlling binder content in carbon article production - measuring slump of pressed mix of carbon and binder prior to baking
Inventor: PETERSON RICHARD WALTER
IPC: C04B35/532
Filed: 1978-09-19
Abstract: In the prodn. of carbon articles by pressing and baking a mixt. of binder (coal tar or petroleum pitch) an a carbon aggregate, the slump of the pressed article is measured to at least hundredths of an inch prior to baking. The relative proportions of binder and carbon in subsequent mixt. is then varied according to the measured slump in order to give the required slump. Used in making carbon anodes for electrolytic production of Al from Al2O3 dissolved in fused cryolite. The optimum binder content of the mixt. is controlled by the slump measured and eliminates conventional vol. and wt. tests on the baked article. Any rejected articles can be crushed and recycled to the mixer thus saving heating costs in baking rejects.

Title: Fine spray droplets separator - is formed from plates with roughened surfaces mounted in bundle
Inventor: BUERKHOLZ ARMIN DR
IPC: B01D45/08
Filed: 1978-12-20
Abstract: System for agglomerating and separating fine liquid droplets out of a gas stream uses a bundle of parallel plates or sheets. These plates are straight and their surface is roughened to produce a turbulent boundary layer. The plates are 0.1-2 m long (pref. 0.2 to 1 m), are spaced 2-50 mm apart and the roughness is formed from elevations and depressions of 0.2-5 mm pref. 0.5- 2m. The plates can have collection channels at the end. They can have a zig-sag section or have traps mounted after them which form pockets. The flow can be controlled by an adjustable damper which moves across the face. Used to remove finely divided droplets from gas streams. Gives a quantitive separation of droplets in the range 2-20 microns at only a fraction of the pressure drop needed for laurella type separations. For the same pressure drop, the efficiency is much improved.
