Title: Flow-through water desalination - using perforated cartridge clamped with flange between outer case flanges
Inventor: ALHAEUSER ERICH
IPC: B01J47/024
Filed: 1980-03-04
Abstract: A device for water desalination without a bypass is a totally enclosed cylindrical tank with a cylindrical cartridge which holds an ion exchange resin between perforated face ends. The cartridge has an annular flange at one end which is clamped between seals and the flanges on the base and on the cover of the cylindrical tank. This ensures a reliable seal by simple means. Any accidental leak is visible at once.

Title: Binary encoding system for low frequency signals for telecommunication - uses individual half cycles providing high or low states
Inventor: DIRR JOSEF ING GRAD
IPC: H04L27/24
Filed: 1980-03-21
Abstract: The method is used for encoding low frequency signals, used with P.C.M. and video, within an existing communications network. This is achieved by allocating each half cycle of the low frequency signal a high or a low state, two or more cycles forming a binary word. Transmission paths with communication bandwidth are multiplexed into a number of channels, one for each transmitted frequency. A bit encoder (Bz) is coupled to an oscillator so as to switch to the next bit after each zero-level crossover, the bit corresp. to the amplitude.

Title: Enamel covered electric cooking ring - has cast iron plate underneath protected by nickel aluminide layer or composite layer
Inventor: LEUZE GERHART
IPC: F24C15/10
Filed: 1980-05-30
Abstract: The electric boiling ring for a domestic cooker or hob, has a coiled heating element embedded in an insulating mass enclosed by a cast iron plate (3). The outside surfaces of the cast iron are covered with a thick enamel layer (6a).

Patent DE-3030185-A1 (DE)
Title: Oxalate removal from e.g. foods, beverages or biological fluids - by reaction with oxygen in the presence of oxalate oxidase to give carbon di:oxide and water
Inventor: KOHLBECKER GUENTHER DIPL CHEM
IPC: A23L5/20
Filed: 1980-08-07
Abstract: In a new process for the enzymatic removal of oxalate, oxalate and oxygen are reacted to give carbon dioxide and hydrogen peroxide by means of oxalate oxidase. Pref., H2O2 formed by the enzymatic reaction is converted into oxygen and water by means of catalase; this avoids a possibly toxic accumulation of H2O2 and allows the process to be carried out in oxygen-poor media. The enzymes (or microorganisms contg. the enzymes) are pref. used in immobilised form. Used for removal of oxalate from foodstuffs and beverages (e.g. beer, tea, juices, fruits) in order to minimise health hazards and (in the case of beverages) and to avoid discoloration caused by oxalate-induced lowering of pH, and from biological fluids such as plasma, serum and urine in order to avoid interference of oxalate with clinical-chemical analyses.
Patent DE-3032249-A1 (DE)
Title: Detachable cable coupling - has locking element to secure cable collar to switch housing
Inventor: BETANSKI FRANZ ING GRAD
IPC: H02G3/06
Filed: 1980-08-27
Abstract: The cable (11) to be clamped is first inserted in an appropriately-sized opening (25), in a collar (10), which in turn is slotted into an aperture (14) in the wall of the switch housing (13). The collar (10) can be accurately located in this aperture (14) by means of the recess and projecting edges (22) around its sides which form guides. A locking element which is then pushed into the cut-out (14) from above after inserting the collar (10), is turned through 90 degrees so that it butts up against the outside face of the housing wall (13). This locks the collar (10) carrying the cable (11) firmly in position in the wall of the casing, (13) after which, the casing lid is closed. A captive screw on the edge of the lid, aligns with a threaded hole in the locking element, and after driving the screw into the thread, the cable collar (10) etc. cannot be released, until the screw is withdrawn and the lid of the switch casing opened.

Title: Insulating layer on the upper part of a container for a liquid fuel, and process for attaching the insulating layer
Inventor: LARSSON TED CONNY
IPC: E04F13/08

Title: Device enabling handicapped persons with their wheelchairs to surmount staircase landings or other barriers
Inventor: RAMSAUER GEORG
IPC: B66F7/10
Filed: 1981-02-20
Abstract: Height barriers are surmounted by handicapped persons in staircase installations by means of inclined lifts. A loaded lift (dead weight and useful load) moving in an inclined direction often involves problems in staircase installations which can only be mastered with extensive constructional measures. The lift for which a patent has been applied only exerts a small load on the staircase. It takes the handicapped person up to the landing level and carries the runway up with it, which is mounted on one side via a pivot. The other longitudinal side of the runway is placed loosely onto the bottom staircase edges in the bottom initial position. It is pushed upwards at an angle along the stairs. The runway shifts into a horizontal position upon reaching the landing level and rests on the crest of the landing. Only half the weight of the runway will load the staircase installation when the handicapped person is being taken up. The handicapped person with his wheelchair can leave the travelling platform upon reaching the landing level and can move out over the horizontally lying runway acting like a bridge. In the case of lifts mounted on perpendicular walls, the runway is fitted in a short length so that, as a flap, it can cover the gap which is present between travelling platform and fixed wall. <IMAGE>

Title: Method for preventing the formation or the growth of algae and slime-forming bacteria in open service-water systems
Inventor: SAUTNER HERBERT
IPC: C02F1/50
Filed: 1981-09-05
Abstract: The invention relates to a method for preventing the formation or the growth of algae and slime-forming bacteria in open service-water systems. The object of the invention is being able to operate an open service-water system free from algae and slime bacteria and substantially free from other bacterial strains. A method is to be created by which, without great technical complexity and cost, the formation or the growth of algae and bacteria is prevented by nonpoisonous means. This is achieved by adding an aqueous methylene blue solution to the service water. A reducing agent stabilising the methylene blue is advantageously added to the methylene blue solution before its use.

Title: Method for fitment of a terminal strip arrangement, especially for relays and contactors
Inventor: MAIK WALDEMAR
IPC: H01R43/20
Filed: 1981-11-27
Abstract: A method is proposed for the fitment of terminal strips, especially for relay and contactor covers. Chambers, into which the terminals are intended to be fitted, are provided in the terminal strips. Each terminal strip in the relay cover is allocated a rail to which a number of terminals are fed. Once the number of terminals specified for the respective terminal strip are present, the terminals are moved along the respective rail to the specified distances and positions. The arrangement of the terminals on the rails now corresponds to the desired, fitted terminal strips on the relay cover. By means of a removal apparatus, all the terminals which are positioned and are held at a distance are removed from the rails together, are moved over the relay cover together in a linear movement, and are fitted into the corresponding chambers of the terminal strips together.
