Title: Slaking lime with excess water - under shearing, using lime and-or water esp. contaminated with sulphate(s)
Inventor: FRANK GUENTER DIPL CHEM DR RER
IPC: C04B2/04
Filed: 1976-08-20
Abstract: Lime is slaked with excess water, using a contaminated lime and/or a contaminated slaking water. Contaminants are esp. sulphates. Shearing forces are applied during or after slaking. Process allows use of recycle water. Shearing prevents slaking gravel formation, leading to abrasion of pipes and pumps. Thus, slaking gravel formation, which was increased from 3.49% to 27.2% (w.r.t. CaO) on replacing distilled water by saturated gypsum water, was decreased to 0.56% under shearing generated, during slaking, by a stirred turning at 8000 rpm.

Title: Vertical paper stack height control - has electrical capacitance mred between opposing capacitor plates for comparison with reference level
Inventor: HEIBER HARTMUT
IPC: B65H1/18
Filed: 1976-09-25
Abstract: A vertical stack (2) of paper sheets in a printing machine is controlled by a sensor with variable capacitance. A capacitor (1) near the top end of the paper stack (2) produces two balanced capacitors with imaginary plates (1") next to the real plate (1) and a second one with plate (1') at the bottom of the stack (2). As the top edge of the paper stack approaches the capacitor plate (1), the capacitance between this plate and plate (1') changes whilst the capacitance with the second plate (1") remains constant. This unbalanced produces a signal which is amplified and then used to control the paper stack supply line.

Title: Snuff or chewing tobacco metering and tin loading system - forms column indexed downwards for tin height and sheared at bottom
Inventor: BALD HUBERT DIPL ING
IPC: B65B37/08
Filed: 1976-12-04
Abstract: The system meters chewing or snuff tobacco and loads it into tins of less than 70mm dia. A vertical column of tobacco is formed (13) , whose dia. is slightly less than the internal tin dia., while its height is more than three times the dia. Tobacco is delivered in a virtually continuous flow to the top of the column from a larger hopper, and gas at a predetermined pressure has free access to the entire top surface of the column. By the creation of a pressure difference between top and bottom of the column, acting in the same direction as the force of gravity, the column is indexed downwards for a height to match that of the tobacco tin, the portion formed being sheared off from the column bottom. It is finally thrust into the tin.
