Title: Process and apparatus for preparing chemically pure oxygen to be used for therapeutic purposes
Inventor: BRATZLER KARL DR
IPC: C25B1/04
Filed: 1987-05-16
Abstract: In a process for preparing oxygen to be used for therapeutic purposes, water is decomposed in a battery of electrolysis cells whose anode space is separated from the cathode space by a liquid-permeable but gas-impermeable membrane, the oxygen formed being continuously drawn off from the anode space. The electrolyte used is potassium or sodium hydrolyside solution in a concentration range of up to six-normal. The apparatus comprises a battery of electrolysis cells having noble-metal, cobalt or nickel anodes, the anode space being separated from the cathode space by a liqud-permeable but gas-impermeable membrane. The membrane used is a fine-mesh gauze made of nickel wire, a sintered plate made of metal, preferably nickel, or a fine-pore gauze made of a hydroxide-resistant plastic, for example polyethylene or polypropylene. The battery is provided with a battery cover plate which contains gas collection channels for the oxygen and the hydrogen and which contains a further channel for replenishing consumed electrolyte water. Traps are situated at the gas outlet channels to trap entrained liquid drops, and an electrical ignition device is provided for burning the hydrogen formed with atmospheric oxygen to produce water vapour.

Inventor: HELLDOERFER REINHARD DIPL ING
IPC: G01C21/32
Filed: 1987-12-30
Abstract: A method for determining and storing relevant data for representing a road network image, which is obtained from a heterogeneous data collection and filed in a data store of an electronic vehicle navigation system. To this end, each street 23 is provided with an identification and the coordinates of keypoint houses called up per street with their allocated house numbers from the data collection as bearing points 24 for the street. A straight line is formed through the bearing points of the lowest and highest house numbers, and the distances of the other bearing points from the straight line are compared with a predetermined boundary value. In order to linearise the course of the street, the bearing points 24 are suppressed if the largest bearing point distance does not exceed the boundary value. Otherwise, the bearing point which is at the greatest distance from the straight line is used as the new end point for a further straight line. <IMAGE>

Title: Harmonica
Inventor: HAETTI ERICH
IPC: G10D7/12
Filed: 1988-03-01
Abstract: Known harmonicas form a chromatic scale by changing over to other tuning plates. If this harmonica is to be played in another register, the player must deviate from the usual blowing pattern. With the new harmonica, playing in any key with the same blowing pattern has become possible by the distributor plate having ducts which are connected with ducts of a key template, the distributor plate having, in the ducts into which two ducts of the mouthpiece plate and three ducts of the key template open, non-return valves which control duct sections between the outer ducts and the central duct of the three ducts of the key template, a duct cell body with at least one chromatic tuning plate being provided, the ducts of which are in part connected to the ducts of the key template, the duct cell body being displaceable in relation to the key template by one or two semi-tones, and the duct cell body moreover being displaceable in relation to the key template within the twelve semi-tones of a scale and engageable by semi-tones. As a result, the otherwise usual harmonicas in other keys can be forgone.

Patent DE-3808091-A1 (DE)
Title: Turret head for lathes
IPC: B23Q16/10
Filed: 1988-03-11
Abstract: A turret head for lathes consists of a fixed housing 1 as well as of a rotary part 3, rotatably mounted in the housing 1, for accommodating fixed and/or driven tools. Arranged between the housing 1 and the rotary part 3 is a releasable locking device 9 which consists of two identical ball rings 10, 10' which can be arranged on as large a diameter as possible on both the housing 1 and the rotary part 3. An oil chamber 16 arranged between the housing 1 and the rotary part 3 serves to unlock the two ball rings 10, 10'. During admission of pressure against the force of a spring 17, the oil chamber 16 pushes apart the housing 1 and the rotary part 3 and thus the two ball rings 10, 10' with their balls 13, so that the rotary part 3 rotates relative to the housing 1, and the desired tool can be put into the working position. The oil chamber 16 is then relieved again and the two ball rings 10, 10' are locked to one another. <IMAGE>

Title: Stripping device for roller grinding machines
Inventor: FRITZSCHE THOMAS
IPC: B02C4/40
Filed: 1989-02-14
Abstract: Wear enlarges the gap occurring as a result of the distancing of the blade from the take-off roller, so that constant resettings are necessary in order to prevent injuries. The object on which the invention is based is to develop a stripping device for roller grinding machines by means of which the size of this gap is kept constant. This object is achieved by means of the fact that a take-up body (13) is arranged movably in the frame (5). A slide rod (10) mounted therein actively communicates with a press device and a run-off plate (2). A spring-loaded hand lever (15) is provided with a lever bore (14), the diameter of which is greater than the diameter of the slide rod (10). The hand lever (15) is mounted in a receiving bore (18) which is located in the take-up body (13). The hand lever (15) has a defined clearance in the receiving bore (18). The invention is used in roller grinding machines for the processing of pasty materials. <IMAGE>
