Title: Device for the illumination of passive displays
Inventor: ZIEGLER WOLFGANG DR ING
IPC: G09F13/02
Filed: 1982-09-28
Abstract: A device is proposed, which serves for the illumination of passive displays with a light source disposed separately therefrom. The device consists essentially of a plate (12), which is disposed in front of the display (10) and which is designed, in terms of its thickness, in the form of a wedge and into which the light of a light source (13) enters via a light guide (15) from the thicker end of the plate (12) at the end face (12a), is reflected at the front surface (12b) of the plate (12), which front surface is inclined out from the plane situated perpendicular to the direction of view (X), and emerges at that surface (12c) of the plate (12) which is situated at a small distance (a) from the display. This device gives an illumination of the display at a steep angle with a small overall depth, as well as a high efficiency of illumination. The device can be used both for incorporation in the dashboard of motor vehicles and the like, and also for indicating instruments in open or closed spaces which have a differing, varying or inadequate brightness (Figure 1). <IMAGE>

Title: Foamed liquor receptacle disposed between a foam generator and an applicator
Inventor: MITTER MATHIAS
IPC: D06B19/00
Filed: 1982-10-09
Abstract: Between a foam generator and an applicator, preferably a slot doctor, there is disposed in the supply line (2) a receptacle which is constructed as a compensating and reservoir vessel. Specifically, a supply line section leads into the interior of the receptacle as far as the underside of a slidably disposed pressure piston which is under a controllable pressure. The position of the pressure piston is detectable. A control means makes it possible to control the rate of flow of foam into the receptacle, it being possible to alter the magnitude of the received foam volume through the slidability of the pressure piston. The pressure piston is supported in its movement by a counterweight, but must work against an adjustable pressure pad. As a result, the foam is under an adjustable, uniform pressure at the point of inflow into the applicator (9). <IMAGE>

Title: Valve tappet for an internal combustion engine
Inventor: DWORAK ULF
IPC: F01L1/14
Filed: 1982-10-23
Abstract: A valve tappet for an internal combustion engine, having a metallic shank (3) serving for its guidance in the engine block, has an insert (2), which is arranged at its lower end (5) and operates against the cams of a camshaft. In order to ensure minimum wear of the functional face (8) of the insert (2), which face operates against the cams, and also low wear of the cams themselves, the insert (2) consists of a ceramic sintered material of high grain boundary strength based on dense, high-melting metal oxides, carbides and nitrides having a theoretical density of at least 95% and, on its functional face (8) acted upon by the cams, has a mean roughness Ra < 0.2  mu m, preferably < 0.1  mu m. The insert (2) is fixed in a metallic shank (3) by casting die-cast aluminium around it or by shrink-fitting, bonding or clamping in a tubular steel shank (3) or a shank (3) produced by forging or turning steel. <IMAGE>
Patent DE-3240356-A1 (DE)
Title: Grinding tool for the machining of brittle media
Inventor: KUMMER HEINZ DIPL ING
IPC: B24D3/28
Filed: 1982-11-02
Abstract: The invention relates to a grinding tool for the machining of brittle media, in particular for the fine machining of glass and quartz, consisting of a body set with diamond pellets. Here, the intermediate spaces between the diamond pellets are filled with a casting resin in such a way that the grinding tool has a closed surface, which casting resin is enriched with fillers, such as, for example, diatomite, and is provided with admixtures having a stock-removal effect. This makes it possible for not only the diamond pellets but also the intermediate spaces to participate in the machining process. Due to the continually present closed tool surface, in particular optical components cemented to bodies and having different heights can be machined. Apart from a reduction in the machining times during the grinding and polishing processes, the use of the grinding tool enables the number of machines required for the preliminary machining of the workpieces to be reduced. <IMAGE>

Title: Roll-shaped optical display device
Inventor: WERBA HANS
IPC: G09G3/00
Filed: 1983-02-01
Abstract: A display device is described which has per display roll a pair of delay lines (La, Lb) into which identical pulse groups having a controllable phase difference can be fed. It is possible, at display sites (Aa1, Ab1; Aa2, Ab2;...) assigned in each case to one another along the two delay lines (La, Lb), relative to which the pulses from the sending ends (10, 11) have different group delays, for discrete light sources (61, 62,...) or a luminous medium (9) present along the entire lengths of the delay lines to be lit up when coincidence occurs at this display site between the two pulse groups propagating through the delay lines (La, Lb). The site of such a coincidence along the delay lines (La, Lb) depends on the controllable phase difference with which the pulse groups are in each case fed into the two delay lines (La, Lb). <IMAGE>

Title: Method and measurement chamber for determining the pore diameter of micro- and ultrafiltration membranes
Inventor: STROH NORBERT DIPL ING
IPC: B01D65/10
Filed: 1983-04-08
Abstract: Method of determining the pore diameter of micro- and ultrafiltration membranes by means of a measurement chamber in which the membrane to be investigated is clamped in such a way that it separates a section of the measurement chamber containing a liquid (liquid section) from a section containing a gas (gas section), and with which the condition is determined in which the gas from the gas section escapes into the liquid section through the membrane (bubble point). In the liquid section (2), which is completely filled with a wetting liquid, for example with water or methanol, and deaereated, the pressure of the gas still remaining after the deaereation is reduced by approximately 0.1 bar; the gas pressure in the gas section (3) is then increased continuously or in steps until the underpressure in the liquid section (2) suddenly drops as a criterion of the passage of the first gas bubbles through the membrane (1); to calculate the required pore diameter D, the sum of the gas pressures then existing on either side of the membrane (1) is substituted as bubble pressure or transmembrane pressure PB in the formula D = (4.O.cos theta )/PB, where O = surface tension and  theta  = wetting angle of the liquid.

Title: Universal, sterile, closed hose systems for artificial respiration, assisted breathing and aerosol therapy of patients
Inventor: LANG VOLKER O PROF DR MED
IPC: B29D23/00
Filed: 1983-07-28
Abstract: Universal, sterile, closed, disposable hose systems for artificial respiration, assisted breathing and aerosol therapy of patients are described, which can be produced as closed hollow bodies in a simple and inexpensive manner by extrusion blow-moulding and subsequent application of external reinforcements. By this means, reusable hose systems for patients can be replaced by disposable systems which are bacteriologically hygienic and simpler and safe to handle. The expensive systems which are currently available on the market and which are still manually assembled from individual parts and then specially packed and sterilised must be regarded as being technically obsolete in the same way as reusable patient systems.

Patent DE-3405749-A1 (DE)
Title: Suction cleaner
Inventor: WOERWAG PETER
IPC: A47L7/00
Filed: 1984-02-17
Abstract: The suction cleaner has a motor-driven suction fan which feeds the washing liquid, sucked off by a suction tool, to a receiving container via a suction line. The maximum filling height in the receiving container is limited by a filling height limiting device which is constructed as a filter. Due to the foam floating on the surface of the washing liquid or due to the washing liquid itself, the throughflow resistance of the flow of suction air which flows through the filter material of the filtering element is increased. As a result, there is a pressure difference between the space outside the filter and the space inside the filter, which pressure difference actuates a pressure difference switch which switches off the fan motor. As a result, the maximum filling height in the receiving container can be limited reliably with little constructional outlay.
