Title: Waste gas chemisorbent materials dried in branch circuit - before return to main flow leading to filter
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/34
Filed: 1980-03-22
Abstract: Plant for treating waste gas charged with chemisorbent material before filtering deviates part of the gas stream through a drying unit which receives wet chemisorbent material. When dried this material is returned by a fan for contact with the gas stream in a conduit leading to a gravity separator which removes gas from solids. Purified gas is delivered to the outlet flue, while used chemisorbent material is ejected. For refuse-burning plant which utilises wet alkaline chemisorption material applied by spray driers to the crude gas stream, but avoids the necessity of contacting the entire body of waste gas.

Title: Permeable material washing - has sprayed water on one side and suction on the other
Inventor: LOEHLEIN RICHARD
IPC: D06B5/08
Filed: 1980-04-01
Abstract: As the fabric (16) is carried by a continuous mesh band (1), dirt and other unwanted matter is washed out by feeding washing medium to one side of the fabric, to be drawn through the permeable material by suction. The process removes matter from the fabric, but prevents mixing and foaming so that the washing medium can be recovered, particularly when washing polyurethane synthetic leather. There are suction boxes (2) under the continuous mesh carrier (1), lying across the direction of travel, trough-shaped with a gutter cross section. There are separators in the base to keep separated washing fluid to one side for further use, and air suction on the other side. Above the continuous mesh (1) there are a number of jets (3) in a housing (4) sealed by a lid at the top, and by slides (5) at the fabric entry and exit points (17,18). There is a suction unit for each suction box (2), which also has a fluid separator and fluid outlet, which syphons the water out to a collection vessel.

Title: Circuit for actuating an eddy current brake for motor vehicles
Inventor: ERNST WERNER
IPC: H02P29/00
Filed: 1981-03-07
Abstract: The actuation of an eddy current brake (WSB) for motor vehicles is effected by the use of an electronic circuit-breaker (ELS). The latter has a saw-tooth generator (SZG) which actuates a switching element (LSG) by means of a comparator (K) and an actuator (AST). The power is set by means of a power controller (LS) in the form of a potentiometer (P) by the driver of the motor vehicle. For braking power which is independent of the speed of revolution, a multiplier (M) can be provided which multiplies the voltage which is proportional to the braking torque by a voltage which is proportional to the speed of revolution of the vehicle component to be braked. <IMAGE>

Title: Electromagnetic flowmeter
Inventor: IJMKER LUCAS
IPC: G01F1/58

Title: Switch having a rotary resistor or rheostat for regulating electrical loads for motor vehicles
Inventor: ENGELBERTH HORST WERNER
IPC: H01C10/36
Filed: 1981-04-11
Abstract: The invention relates to a switch having a rotary resistor or rheostat for regulating electrical loads for motor vehicles, having a parallelepiped (box-shaped) housing which has at least two parts and is constructed such that both wound wire resistors having a ceramic or plastic carrier and film resistors can be accommodated in it, using virtually identical components, in the manner of a printed circuit on a carrier consisting of synthetic-resin-bonded paper, plastic or ceramic, without any design change to the basic concept of the switch. For different electrical loads, only the resistor carrier boards with the resistors fitted thereto need be changed or replaced, while the housing parts and the mechanical drive for the resistors is virtually identical as a result of a switching segment having gearwheel transmission from the tool side. The switch design is in consequence particularly easy to assemble, since all the functional parts in all the embodiments are preinstalled in the same manner as assemblies and can be inserted into the common housing body from the side. <IMAGE>

Title: Method and apparatus for the reading of road maps and town plans by means of microfilms
Inventor: RUSS ARTUR
IPC: G09B29/10
Filed: 1981-05-12
Abstract: Hitherto, no suitable apparatus has been known for the simple reading off of the current location on road maps or town plans, especially in darkness. Driver and passengers have to make an excessive effort to locate their position and determine the next stage of the route, the more so since reading of the map material is made much more difficult in darkness. These disadvantages are eliminated by the method introduced. The map material is recorded on microfilm and can then be made optimally visible by means of various enlargements - especially during night driving. A previously known method is exploited for a new purpose.
Patent DE-3119364-A1 (DE)
Title: Window or door with a ventilation device
Inventor: TATARCZYK ARTUR
IPC: E06B7/02
Filed: 1981-05-15
Abstract: The invention relates to a window or door in which modified U-shaped profiles are fitted on the lower and upper frame sections in order to allow good ventilation and also good noise protection. The base of the U profiles is flush with the inside of the frame and exhibits several openings, which are opened and closed with the aid of a sliding element guided in the U profile. An air connection between the two sides of the window or door, even when closed, can be produced via these openings, the hollow space of the U profiles and water drainage channels in the lower frame section, and a gap between the upper frame and the window casement or door leaf sections. Thanks to the flow of air which changes direction several times, the incoming cold outside air is prewarmed, the warm interior air flowing out transfers some of its heat to the frame and effective noise protection is achieved. A simple and cheap mortise and tenon or slit and tongue joint is used to manufacture the frame. <IMAGE>

Title: Composition for hair growth
IPC: A61Q7/00
Filed: 1981-05-19
Abstract: Compositions hitherto disclosed for hair growth usually have only a relatively short action so that it is necessary, to prevent further hair loss, to repeat the treatment at particular intervals of time. In order to make such disadvantageous subsequent treatments substantially superfluous and to make it possible for hairs which remain long to grow, the invention provides a composition for hair growth which consists of a first component for external use and of a second component for internal use. The first component is in the form of a liquid and is composed of the following ingredients, which are mixed together in the stated ratios by weight:     a) 10 weight units of undiluted burdock root pressed juice,   b) 45 weight units of undiluted stinging nettle pressed juice,   c) 20 weight units of 17% strength ethyl alcohol as preservative,   d) 25 weight units of water.  The second component consists of a mixture of     e) 90 weight units of dried stinging nettle leaves and   f) 10 weight units of dried burdock leaves, the latter mixture being prepared as an infusion with water. The advantage of the composition for hair growth is that not only is there formation of the customary downy hairs which, experience has shown, are rapidly lost again but also that hair growth continues beyond the downy hairs and normal hair may develop.

Title: Process for the production of a thermoplastic film from polyolefins by calendering
Inventor: THINNES KLAUS DIPL ING
IPC: C08J5/18

The invention relates to a process for enabling calendering by controlling the melt viscosity of the polyolefins to be calendered. For this purpose, certain organic or inorganic fillers in predominantly fibrous form, for example wood pulp or asbestos fibres, are suitable.

Abstract: The invention relates to an arrangement for determining the speed and sense of rotation of a shaft. A soft magnetic rotor (12) having preferably six poles (14-19) extending in the radial direction is arranged for this purpose on the shaft (13).
