Patent DE-2042402-A1 (DE)
Title: Pure phthalates and high dicarboxylates prodn - and higher dicarboxyla - by sequential esterification distillation and deodori
IPC: C08K5/12
Filed: 1970-08-27
Abstract: Phthalates and esters of higher aliphatic dibasic acids with alcohols are prepd. by sequential catalytic esterification, distilling off of excess alcohol, and deodorising; the latter step is effected at 160-180 degrees C and 1-15 torr without previous neutrallisation. This is followed by filtration with use of filtration aids without ozonisation. Application of relatively high temps. and vacuum below 15 torr enables neutralisation step to be dispensed with, so saving about 20 hrs. processing the per reaction charge. Used as plasticisers and in mfre.. of lacquer resins and paints.

Title: Self cleaning filter for recirculating fluids - having side stream from pump used as jet on horizontal filter surface
Inventor: SCHIELE JOSEF
IPC: B01D29/00
Filed: 1974-01-22
Abstract: Filter for use on systems where a recycled liquor is used consists of an inverted hemisphere across which a medium or filter cloth is stretched. Below this cloth is a pipe with holes forming jets which impinge on the filter cloth, removing any slurry or deposits which might tend to form. The jets are fed from the pressure side of the pump which recycles the liquid while the filter is on the suction side. The jets represent a side stream off the main recycle. The filter uses either a polyester weave or a wire mesh. It is connected via a throttling valve to the pressure side of the pump, this being manually controlled. The jets are fed via a line which is a flexible, pressure resistant rubber tube, arranged so that the jets spray vertically or at an acute angle onto the surface. The filter surface can be flat, spherical or cylindrical. Of use wherever liquid is recycled and where it can pick up dirt e.g. lathe coolant recirculation or treatment of timber for impregnating and coating it. Unless the filter is regularly cleaned, the pressure at the delivery sprays falls off and can cause variations in product quality. The filter is self cleaning and ensures a continuous supply of liquid. The cleaning action can be adjusted by a valve.

Title: Modular assembly system for cladding, dividers etc - dove-tailed grooves in panel edges permit panel joining using locking plugs
Inventor: HAENER ALFRED
IPC: E04C2/38
Filed: 1974-05-09
Abstract: A modular assembly system for the construction of room dividers or claddings utilises interlocking plastic components. The main panel unit consists of a square or rectangular honeycombed (6) centre section. The edges of the panel are formed in solid rigid plastic sections (4) and each edge has a pair of dove tailed profiled slots (8). When panels to be joined are located either in line or perpendicular to each other the dovetailed grooves align. A tapered plug of a mating profile is pressed into the profiled grooves to form a secure joint. In this way the structure formed is rigid, but provides the possibility for re-use. A variety of configurations are possible with the one basic panel design.

Title: Densifying sludge in sewage farm settling tanks - by vibrating submerged plates, cylinders, etc. to accelerate precipitation
Inventor: FROSSARD PIERRE CH
IPC: C02F11/12
Filed: 1974-08-21
Abstract: Sewage sludge is densified by setting in vibration, by means of a vibration generator, the surface of a body submerged in the fluid, in such a way that the vibrations are transmitted to the sludge and water mixture. The vibrations are directed almost at right angles to the surface of the submerged body and are generated at a frequency and amplitude which are both variable, and the depth to which the body is submerged is also variable to regulare the densifying process according to the conditions. Quicker and improved densifying of the sludge is achieved. The device can be installed in existing tanks which were not intended as densifiers.
