Patent DE-3710842-A1 (DE)
Title: Electromagnetic brake arrangement, in particular for ergometers
Inventor: FEY RAINER
IPC: H02K49/02
Filed: 1987-04-01
Abstract: The electromagnetic brake arrangement comprises a field (excitation) winding (5) which is fed from a generator winding (7) and on the one hand excites the generator winding (7) and on the other hand induces a braking torque in a short circuit winding (9) which is moved with the generator winding (7). The excitation current of the excitation coil (5) is controlled by a transistor (13) of a current control circuit which holds the excitation current, and thus the braking torque, to a value which can be set at a reference voltage source (19). The iron (ferromagnetic) circuit of the excitation coil (5) has remanent magnetic properties which ensure initial self-excitation. The components of the control circuit, in particular, are supplied with operating voltage from the generator winding (7) via a rectifier circuit (11). A resistor (47), which is directly connected to the rectifier circuit (11), turns on the transistor (13) even if the operating voltage is not yet sufficient for the proper operation of the control circuit. As a result, the brake arrangement is ready to operate even when the magnetomotive force (mmf) is relatively slight.   <IMAGE>

Title: Method of testing the water permeability of exterior walls and/or poor room ventilation and use of this method
Inventor: GRUEN HORST
IPC: G01N15/08
Filed: 1987-07-22
Abstract: Method of testing the water permeability of exterior walls, primarily of brickwork, and/or poor room ventilation and use of this method. To answer, in a simple manner, the question whether there is present a lack of sealing in the facade or insufficient room ventilation it is proposed that the surface temperature be measured on the exterior wall, primarily on the room side, and the cold of evaporation or heat of condensation in or on the wall be determined together with the theoretical values derived from the exterior temperature and the room temperature, with cold of evaporation indicating water permeability and heat of condensation indicating poor room ventilation. Cooling, desirable in summer, of enclosed rooms can be achieved by, on hot days, besides the temperature-stabilising storage capacity of all walls, the water absorption and the re-evaporation giving effective degrees of cooling by means of targeted construction and coating of the outer walls.

Title: Height-adjustable, rotatable and interchangeable serving plates
Inventor: MUELLER HEINZ
IPC: A47G23/08
Filed: 1987-12-22
Abstract: Serving plates which are fixed on a baseplate or a foot or are rotatable thereon are known. The invention relates to round serving plates which, by means of a combined height-adjusting and locking device which can be fitted onto and withdrawn from a standing tube fixedly connected centrally and perpendicularly to a serving baseplate, can be adjusted in height in several steps, can be easily rotated on ball bearings and can be interchanged as desired and which can be used individually or also in a multiply combined manner. They can be used on any dining table, particularly advantageously however on small, round, non-extendable dining tables having only one central standing leg and fixedly installed tables, such as in caravans and small watercraft. The advantages consist, in particular, in the fact that the overall serving area of the dining tables and thus the convenience of use is increased, it being possible to turn the various foods using the serving plates to each sitting place for the purpose of self-service, and also serving plates in a variety of design and sizes or, for example, serving trays with several internal subdivisions lead to manifold, virtually unlimited serving and decorative possibilities.

Title: Process for polymerising and copolymerising lactams and corresponding polyamides
Inventor: SEBENDA JAN
IPC: C08G69/20
Filed: 1988-08-01
Abstract: The invention relates to a process for polymerising or copolymerising lactams, wherein the polymerisation initiators used are N-substituted lactams whose N-substituent is a radical of an organic or inorganic acid. The process is suitable in particular for the polymerisation and copolymerisation of more than 7-membered lactams. The polymerisation initiator is used in an amount of at least 0.1 mol%. It can also be produced in situ in the polymerisation system by addition of suitable reagents which form appropriate N-substituted lactam derivatives with the lactam(s) to be polymerised. The substituents on the N-substituted lactams are preferably derived from organic or inorganic oxo acids and are in particular acyl, alkylsulphonyl, arylsulphonyl or phosphoryl groups which are condensed onto the amido group. This process makes possible the polymerisation of lactam at appreciably lower temperatures than with conventional processes and leads to more homogeneous polymers.
Patent DE-3827431-A1 (DE)
IPC: A61B10/00
Filed: 1988-08-12
Abstract: A sticking-plaster consists of a highly flexible basic material (10) the front surface of which is provided with an adhesive coating (12). The adhesive coating (12) is covered by a detachable protective cover (14). The rear surface of the basic material (10) of the sticking-plaster adheres to a detachable rear part (16) which is stiffer than the basic material. The sticking plaster is therefore easier to manipulate after the protective cover (14) is detached. This in turn improves the flexibility of the basic material (10). The sticking-plaster is therefore less affected by movements and adheres more firmly.

Patent DE-3840151-A1 (DE)
Title: Concrete and other construction materials
Inventor: NILL WALTER
IPC: C04B22/00
Filed: 1988-11-29
Abstract: Concrete comprises cement, sand (gravel), aggregates and water. To increase security against damage by unauthorised persons, active substances in liquid, solid or gaseous form are mixed into the concrete. These substances become active as soon as they are exposed by physical or mechanical influences such as drilling, cutting or burning, etc. By means of the evolution (release) of the gases or liquids which are corrosive or act on the eyes, the skin and/or the respiratory tracts (bronchi), the intruder is driven off or forced to give up his/her intention of breaking in. Other materials in which the active substances are incorporated can also take the place of concrete.

Title: Lens antenna
Inventor: HUDER BERNHARD DR
IPC: H01Q15/12
Filed: 1988-12-01
Abstract: The invention relates to a lens antenna by means of which a directional characteristic can be implemented with a greatly different lobe width in two orthogonal intersecting planes without the plane of the linear polarisation also being defined by the definition of these planes. The antenna comprises a rotationally symmetrical feedhorn radiating element with a rotationally symmetrical polar diagram which irradiates a lens which is curved in a concave shape and consists of dielectric material with a circular aperture. On the side facing the feedhorn radiating element, the lens has different lens contours in two orthogonal intersecting planes, the contour in the first intersecting plane being selected such that a spherical wave originating from the focus of the lens is changed into a wave having a planar phase front after passing through the lens, while the contour in the intersecting plane which is orthogonal thereto is selected such that the spherical wave originating from the focus still has a non-planar phase front after passing through the lens.
