Patent DE-2158675-A1 (DE)
Title: Food-pulp drying plant - with continuous re-cycling of drying gas esp nitrogen
IPC: F26B21/08
Filed: 1971-11-26
Abstract: The pulp, preheated in a heat exchanger by the hot gas efflux from the drying tower, is sprayed under pressure into the tower and comes in contact with the hot drying gases which carry off the pulp in powder form to a separator from which the moist gases pass to an absorber assembly esp. using LiCl which extracts the water vapour from the gas efflux. The absorber is then regenerated by continuous or intermittent, gas esp. air at high temp. esp. >100 degrees C. After drying the nitrogen is reheated before being fed back to the drying tower. Thermal efficiency, flavour and aroma preservation and protection from bacterial damage are achieved.
Patent DE-2159830-A1 (DE)
Title: Water desalination plant - with thermal storage heat exchangers alternately condensing and evaporating
IPC: C02F1/04
Filed: 1971-12-02
Abstract: The plant includes two heat exchangers each filled with hollow elements containing a substance having a high specific latent heat of fusion, a vapour compressor, a salt water tank, purified water tank, pumps. The plant is operated on the batch principle using the heat exchangers alternately for vaporisation and condensation. Thus, salt water is first passed through a first heat exchanger, where it is evaporated and the substance contained in the elements in solidified, then the steam produced is compressed in the compressor, and passed to the second heat exchanger, where it is condensed, producing pure water which passes to a tank. Heat of condensation is thus stored in the elements and when the heat of fusion of both heat exchangers has been exhausted, the residual salt water is removed from the first exchanger, and the functions of the two exchangers are then reversed. Specifically, the thermal storage material consists of hollow plastic particles, optionally filled; cast iron with high silicon content; or carbon.

Title: Explosive weld cladding of hollow object - preceded by filling with an easily removable metal
Inventor: PRUEMMER ROLF DR
IPC: B23K20/08
Filed: 1972-09-29
Abstract: The external surface(s) of hollow objects is/are cladded by explosive welding after their interior has been filled up with an easily removable metal which can be removed by melting, dissolving or similar process after completion of the welding operation. If on part of the surface requires cladding the object is surrounded there by fusible metal which is cast in a mould round the object leaving only the surface to be clad exposed. The method prevents deformation of the object on explosive welding.

Title: Carbon-contng waste wet-oxidn
Inventor: FASSELL MARTIN W
IPC: C02F11/08
Filed: 1972-09-29
Abstract: Wet-oxidn. of C-contg. waste material (I), by contacting an aq.dispersion of (I) with an oxidising gas, takes place in a horizontal reactor, sub-divided into several generally cylindrical, inter-connected compartments. Aq. dispersion of (I) is introduced continuously near one end of reactor and moved through reactor, from compartment to compartment. Oxidised dispersion is taken out near opposite end of reactor.

Title: Dough mixing and kneading at very high speeds - one of two concentric rotating arms can be reversed
Inventor: RUOHONEN LEEVI KALEVI
IPC: A21C1/02
Filed: 1973-07-03
Abstract: A dough mixing and kneading machine comprises a vessel in which mixing and kneading arms, at least two in number, rotate in concentric circular paths. For preference, the outer arm travels at a higher speed than the inner, and its direction of rotation can be changed as required. The outer arm is further secured to its crank on driving shaft so that when turning in one direction, it pivots on its joint to a position closer in contact to the vessel wall, whilst when rotation is reversed, it takes up an attitude at right angles to the crank. Reduces normal mixing and kneading time from between 15 to 20 mins. to only 3 mins.

Title: Telescopic support column for gymnastic horizontal bar - has underfloor outer cylinder with pneumatic brake action
Inventor: HARTMANN WILLI
IPC: A63B3/00
Filed: 1973-09-05
Abstract: The column consists of a hollow square tube which can be moved up and down in the outer cylinder. The latter is sunk below floor level. The lower end of the column is fitted with a piston cap and a pliable sealing cap similar to those used in bicycle pumps. A rubber disc valve is fitted over air ducts passing through the piston unit. The closed lower end of the cylinder tube contains a quantity of lubricant. During lowering of the column air pressure increases and together with the lubricant acts as a shock absorber. The air can escape gradually through a small central air passage. The design eliminates counter-balancing weights and pulleys. A lock mechanism is fitted at the upper end of the cylinder tube.
