Title: Shelter frame elements
Inventor: UNTERLAENDER JUERGEN DIPL ING
IPC: E04H9/08
Filed: 1984-12-29
Abstract: DIY shelter comprising profiled trussed-frame elements consisting of structural steel. The frame profiles are bolted together according to the modular-construction principle and can be additionally reinforced in accordance with static requirements. By introducing basic elements, the size of the shelter can be extended from the basic type for 8 people to 25 people. No additional outlay on shuttering is necessary. After assembling and connecting the individual parts, the steel frame module is cast in concrete. All installation parts of the shelter are contained in the set of structural units. The elements can be carried and/or installed by two people. Possible applications:   in terms of wall thickness, designed for installation outside the dwelling beneath the ground; by arranging greater wall and/or ceiling thicknesses, any other installation is possible (in existing buildings, beneath new buildings, partially jutting out of the ground).   <IMAGE>

Title: Switch insert for installation in flameproof housings which are encapsulated in a pressure-tight manner
Inventor: BRAEMER WILHELM
IPC: H01H3/20
Filed: 1985-02-01
Abstract: The invention relates to a switch insert 1 which is used for installation in flameproof housings 4 which are encapsulated in a pressure-tight manner. Said switch insert 1 is provided with a switching handle 29 which acts via a switching shaft 10 (which is locked in its individual switching positions and is supported in an axially sprung manner) on a switch 8 which is located in the housing interior 5. The end of the switching shaft 10 has an obliquely running transverse hole 27. The shaft 28 of the switching handle 29 passes obliquely through said transverse hole 27. On both sides of the switching shaft 10, the shaft 28 of the switching handle 29 engages in in each case one opening 35, 36 in the housing part 23, which openings 35, 36 run in the operating direction of the switching handle 29 and expand like elongated holes. The two openings 35, 36 are located diametrically opposite one another and are arranged offset with respect to one another in the axial direction of the switching shaft 10. The shaft section 38, whose diameter tapers, is pressed into recesses 37 in the opening 35 which is adjacent to the switching handle 29, by the spring force which acts on the switching shaft 10, and is fixed here in the respective switching position. <IMAGE>

Title: Electrically driven air humidifier according to the evaporation principle
IPC: F24F6/04
Filed: 1985-03-04
Abstract: An electrically driven air humidifier according to the evaporation principle with a basic shell, in which a water bath is situated. The supply to the water bath takes place from a water container which is constructed on the basic shell. Submerged in the water bath is the lower side of an evaporation mat which sucks itself full with water by its own capillary action. A hood lies on the basic shell and covers the evaporation mat. Fastened on the inner wall of the hood is a collar which serves as an air duct and in which a fan is arranged. The collar is equipped with a sealing surface, against which an air-cleaning filter is pressed by means of at least one holding piece. Each holding piece engages in at least two locking elements which are arranged in a fixed manner inside the inner space of the hood. The air is humidified by the evaporation mat and cleaned by the air-cleaning filter.

Patent DE-3537611-A1 (DE)
Title: Wire clamp
Inventor: VAHL HARALD WILFRED
IPC: F16B7/04
Filed: 1985-10-23
Abstract: The invention relates to a new type of wire clamp for intersecting wires, the clamp being arranged on a tensioned, flexible, rigid wire and, with the aid of the tensioning and of the elasticity, fixedly clamping the intersecting body, e.g. the wire. The two wires are connected together via the clamp in a frictionally locking manner, with the result that, after exceeding a predetermined force, sliding is possible in order that rupture of the wires is avoided. The clamp can be fastened easily on a pre-tensioned wire by hand and does not damage any of the wires, even in the possible event of sliding. For special application in movable insulation screens in greenhouses, the shape is adapted and additional parts may be mounted for better guidance of the screens. None of the known clamps combine all the abovementioned properties.

Title: Method for determining the spectral distribution of nuclear magnetisation in a bounded volume
Inventor: MCKINNON GRAEME COLIN DR
IPC: G01R33/483
Filed: 1986-05-17
Abstract: In a sequence having three successive layer-selective radio-frequency pulses, the nuclear magnetisation is additionally dephased by a magnetic gradient field before the second radio-frequency pulse. This dephasing is reversed by applying the gradient field with opposite polarity during the second radio-frequency pulse. The temporal variation in this gradient field is selected in this case such that the time integral over the magnetic gradient field from its being switched on up to the middle of the second radio-frequency pulse is zero. <IMAGE>

Title: Method for the production of a groove milling cutter and groove milling cutter produced by this method
Inventor: ENKE WOLFGANG DIPL ING
IPC: B24B19/04
Filed: 1986-07-10
Abstract: In a method for the production of a groove milling cutter for wood, plastic or similar materials from a rotationally symmetrical base body (1), two mutually opposite flutes (4A, 4B) are milled in or ground in from the front end of the milled part to be formed from the base body. In a first operation, a first flute (4A) with a cutting edge (12A) is ground into the base body (1) at a curved section (10) of a profile-grinding wheel (2). At the same time, by means of a straight section (14), the cutting back (15B) of the second cutting edge (12B) still to be formed is sharpened. During this procedure, the base body (1) is also at the same time continuously turned about its longitudinal axis (3) as the profile-grinding wheel (2) is advanced. In a second operation, the second flute (4B) with the second cutting edge (12B) is ground in, while at the same time the first cutting edge (12A) is sharpened at the cutting back (15A). <IMAGE>

Title: Filter for compensation of the brightness fall-off in the image plane of a lens
Inventor: KUTTNER PAUL DIPL PHYS DR
IPC: G02B5/20
Filed: 1986-10-28
Abstract: The invention relates to a filter for compensation of the brightness fall-off in the image plane of a lens with a predetermined course of the transmission T (w), which depends on the image angle  omega , the filter having a central circular region with a constant transmission value. For a filter, in which the diffraction phenomena impairing the image quality can be avoided and which nevertheless can be manufactured in an easy and economical manner, it is proposed that the filter has, concentrically with the central circular region, one or more annular zones. In this case, the transmission within a zone has essentially a constant value. The radial extent and the transmission value of each zone are dimensioned in such a manner that at every point of the filter the amount of the difference between the transmission value fixed for this point by the equation T (w) and the transmission value of the associated zone always lies below a predetermined limit value g.

Patent DE-3700763-A1 (DE)
IPC: A47K1/04
Filed: 1987-01-13
Abstract: A fitting arrangement for washbasins which can be incorporated all-round in a fitted table and for inserted washbasins which partially project from the fitted table (1) is described. A recess (5) for receiving the underside of the washbasin is made in a laminated carrier board serving as a table top (6), the edge being cut off with the exception of a projecting laminate (7). The projecting laminate (7) is glued to a plastic adapter ring (11) or to an adapter ring piece (4) which is otherwise held firmly in the cut-out portion. The washbasin edge is located underneath the adapter. Gaps are filled with sealing material. Washbasins can thus be built in with an attractive shape and in a simple way, without the unavoidable individual tolerance deviations having to be taken into account. <IMAGE>
