Patent DE-2262300-A1 (DE)
Title: Surface area determination on workpieces - by determining weight of pre-viously applied uniform surface layer
Inventor: LIEBER HANS-WILHELM PROF DR IN
IPC: G01B5/26
Filed: 1972-12-20
Abstract: The surface area of workpieces is determined by a method involving a chemical or electrolytical pre-treatment to impart a smooth surface to the workpiece, and then a coating with a uniform layer by a chemical treatment. This layer is afterwards dissolved out for determination of the amt. of dissolved surface layer, from which the surface area of the workpiece can be calculated. >=1 of the processes of coating or stripping of the layer must be carried out for a fixed period of time in a soln. in which material transport is solely determined by speed of diffusion. The surface layer can be produced by flash plating or phosphating, oxidising, chromating etc. The method yields very accurate results and can be used for irregular shaped workpieces.

Title: Vegetable fibres treatment for chipboard prodn. - without preliminary cutting or beater mill stages, using combined radial and axial flow mill
Inventor: VOELSKOW PETER
IPC: B27N1/00
Filed: 1972-12-29
Abstract: Material of vegetable origin, e.g. wood, cotton, maize straw, sugar cane waste, is cut to 10-60 (30-40)mm fibres, then, if too brittle, is humidified in an unpressurised screw conveyor, then pulped in a revolving mill with beater blades in a radial space en route from central inlet to the peripheral grinding ring where it passes along an axial space between revolving blades and an internally ribbed, fixed annular surface. This is opt. followed by drying and sifting (coarse core material, fine outer layer material). The fibres are then coated with adhesive and pressed to form boards.

Title: Heat pump for central heating etc - can be used for cooling, air conditioning swimming pools etc.
Inventor: GIGL RUDOLF
IPC: F04C29/04
Filed: 1974-04-17
Abstract: Heat pump consists of a rotary slide and two heat exchangers. The rotor and blades and two walls of the pump consist entirely or at least superifically of material having poor heat conductivity, e.g. plastics, to allow adiabatic expansion and contraction, while the other two walls are made of material having good heat conductivity, e.g. metal, to allow isothermal expansion and contraction. The walls and blades have matching shapes which may be triangular, sinusoidal, rectangular, square, trapezoidal or semicircular. The Carnot left circulating circuit process lies at the base of the pump usage which ensures the highest possible use of heat energy generated from the drive power.
