Patent DE-2456493-A1 (DE)
Title: Fixing and sealing of membrane capillary tube bundles - into end flanges using layers of different resins
Inventor: SCHOLZ HANS-PETER DIPL ING
IPC: B01D63/04
Filed: 1974-11-29
Abstract: Bundles of membrane capillary tubes are fixed into end flanges using cold setting materials such as resins or elastomers. A number of layers or resin are used and the final composite structure includes at least one layer which remains fluid and/or one layer which remains reversibly deformable (elastic). Defective tubes are sealed off by sucking a setting resin into each end in turn whilst a positive pressure is applied to the other tubes to prevent ingress of resin. The tube bundles are used in liq. sepn. processes such as permeation, reverse osmosis, dialysis and ultrafiltration. The fixing method does not require machinery such as centrifuges and is cheap and simple.

Title: Grape juice extrn. in drainage tanks with slotted partitions - with screw conveyors alternately charging continuous grape press
Inventor: KAEDING GUENTER
IPC: A23N1/00
Filed: 1975-05-30

Title: Transferring melt under vacuum to mobile pressure vessel - in sequence, quickly without hardened matter interfering with joints
Inventor: DUCHSCHERER FRANK
IPC: B29B7/26
Filed: 1975-09-22
Abstract: An arrangement for rapidly transferring a mass of molten synthetic resin or similar matter from a mixer under vacuum to a mobile pressure vessel, has a drain connecting a pipe enclosing the bottom outlet valve of the mixer. The drain connection has a double mantle forming an annular chamber with a valve connection and a sealing flane joining the drain to the outer mantle, through which drillings connect to the chamber. The cover of the mobile pressure vessel has a vertical tubular connection with a flange, the bore of which is opened out to receive the inlet pipe projecting through the hole in the mantle of the pressure vessel. Bores through the flange connect a chamber to another chamber, the connection and the pressure vessel. At least two grooves are provided for sealing rings.

Title: Gallium phosphide deposition on stainless steel, molybdenum - or tungsten by thermal reaction of gallium tri-alkyl and phosphine gases
Inventor: WANG CHIH CHUN
IPC: H01J1/32
Filed: 1975-11-13
Abstract: In the deposition of GaP on a substrate of stainless, Mo or W gaseous GaR3 and gaseous PR'3 (in which R and R' independently are alkyl or R' can be H), pref. GaMe3 and PH3, are reacted thermally over the substrate, pref. at 700-900 degrees C. p-Doping can be produced by treatment with gaseous ZnMe3, ZnEt2, CdMe2 or CdEt2 and n-doping by treatment with gaseous H2S. The substrate with the polycrystalline GaP and a coating of a material reducing the work function is used as electron emitter. The process makes it possible to deposit polycrystalline grp. III-V cpds. esp. GaP, on certain metal substrates, unlike the chloride process, which gives corrosive by-prods. These metal substrates have the advantages of flexibility of available shapes and low prime costs.

Title: Electrically heated swimming pool - prevents ice pressure build up using LV heating cable suspended in water and floating thermostat
Inventor: RAMMO EDGAR RIGOBERT
IPC: E04H4/06
Filed: 1976-01-17
Abstract: The electrically heated unit, with thermostatic control, is for the prevention of formation of closed ice coverings and thus damage to the walling caused by excessive ice pressure, in unheated swimming pools during the winter. This involves a low tension heating cable, of the requisite heating capacity, suspended in the water and electrically heated, so as to preserve ice-free strips about 6-8 cm wide on the water surface, preventing closed ice cover and intense pressure from being built up. There is a regulating and safety double thermostat, floating on the water, to switch the heating on or off, according to surface temp. The cable can be hung lengthways or crossways, from the pool sides, to curve 5-8 cm below the surface, held in place by floating cushions with holding lines, or by floating tubes.

The end section shape may be corrected or straightened in this process, and several such sections may be treated simultaneously. The shaped unit can be electrically or otherwise heated by a flameless source, and its contact surfaces can be adapted to the required end section configuration. It may be fitted with a handle, and automatic contact surface temp. control.
