Inventor: JAEGER WOLFGANG DIPL ING
IPC: G01N29/02
Filed: 1984-10-27
Abstract: 1. A method of examining the filling gas of insulating glass panes or the like having at least two individual panes and a gas-filled space therebetween, the concentration of at least one dense gas or the like in such space being ascertained by measurement and evaluation of the speed of propagation in such space of a signal parameter impressed on one of the panes, the sought-for gas concentration being calculated from such measurement and evaluation, characterised in that the signal parameter is a sound signal and the sound speed is found from the thickness of the space and the average resonant frequency therein in tuning through a frequency interval of standing waves which are formed.

Title: Gradient coil assembly for use in an imaging system operating with nuclear spin resonance
Inventor: STAFFORD-ALLEN ROBIN
IPC: A61B10/00
Filed: 1984-12-05
Abstract: In general, the invention relates to an imaging system operating with nuclear spin resonance for medical diagnostic purposes. In such a system, a current pulsed at a low frequency is applied to the gradient coils used for establishing the respective image section plane in the object examined (patient), as a result of which mechanical forces are exerted on the coils and the supporting body carrying them, with a frequency which is within the audible range and which become noticeable as a disturbing noise. This noise generation is to be reduced as much as possible by the invention. 
<??>A construction of the support or carrying body for the gradient coils is described in the form of an essentially cylindrical part in which annular parts and connecting parts connecting these annular parts to one another in the axial direction are machined out by means of suitable recesses, the annular parts being used for supporting and holding the legs of the gradient coils which are mainly active. Due to this configuration, in connection with the manufacture of the support body of a noise-absorbing material, an extensive reduction in the interferring noise generated is achieved.
Patent DE-3501371-A1 (DE)
Inventor: SCHARF HELMUT DR
IPC: B01D7/02
Filed: 1985-01-17
Abstract: For the non-clogging, fractional desublimation of vapor-phase solids contained in a gas-vapor mixture, the gas-vapor mixture, exiting at high velocity from a nozzle, is mixed with a cooling gas, likewise exiting at high velocity from another nozzle. The gas-vapor mixture and the cooling gas flow toward each other, the axes of the two gaseous streams being a straight line. Fractional desublimation of the solids is attained by adjustment of flows leading to the regulation of the temperature and residence time of the cooled gas-vapor mixture. This desublimation system is capable of degrees of efficiency and solids purities higher than 99%.

Patent DE-3515939-A1 (DE)
Title: Spoked wheel
Inventor: HOERMANSDOERFER GERD
IPC: B60B1/04
Filed: 1985-05-03
Abstract: Spoked wheel for bicycles, motor cycles, children's prams, or other similar vehicles, comprising a rim with tyre, a wheel hub with flanges and a set of spokes. The spoked wheel according to the invention is characterised by novel spokes which no longer have spoke heads but instead have a double bend. The spoke according to the invention is twice the length of conventional spokes. Due to the number of spokes being halved thereby, the threading effort when spoking the wheel is reduced. The costs of the spokes are reduced because the production of the spoke head is omitted and replaced by a simple bending process. This method of production allows the problem-free use of high-tensile steel wires as semi-finished starting products.

Title: Hollow profile
Inventor: MOELLER HUBERT
IPC: E04B2/14
Filed: 1985-06-14
Abstract: The invention relates to a hollow profile having at least one cavity, extending in the longitudinal direction of the hollow profile, and at least one reinforcement insert which is embedded in the material of the hollow profile and consists of a non-extendable material. The hollow profile is designed in the shape of a board and has an essentially rectangular cross-section, a fabric, as reinforcement insert, being embedded in the upper wall and in the lower wall of the hollow profile and a layer consisting of soft, compliant material being provided on at least one outer surface of the hollow profile, with the result that said hollow profile can be used particularly expediently as a floor covering or also as a wall cladding, stair cladding, etc. As a result of the fabric inserts, the hollow profile has an unusually high flexural strength and resistance to torsion and can thus be produced with a small thickness. The material of the hollow profile preferably consists of a plastic/wood fibre mixture.

IPC: B60K15/04
Filed: 1985-09-26
Abstract: In the case of a closure for a petrol filler neck 101 of a motor vehicle a hollow cylindrical closing section 102 is factory-fixed on top of the neck, with an inwardly directed threaded collar 121, on which a reduction sleeve (adapter) 104 is screwed in, secured against rotation, for retrofitting where unleaded fuel is to be used. This reduction sleeve (adapter) 104 with an inside diameter at the narrowest point of < 25mm is made in a sheet metal thickness which is selected so that it is smaller than the usual gap between the threaded collar 121 and an outside thread 132 of the cylindrical middle section 131 of a screw-on filler neck cap 103. The screwed-in reduction sleeve (adapter) 104 with a through-hole 144 is firmly seated, secured against rotation, on a pin 112, which is part of an additional venting valve and directed approximately radially inwards in the filler neck. When the filler neck cap 103 is screwed on, this pin 112 is pressed down in an axial direction in order to open the venting valve. <IMAGE>

Patent DE-3614197-A1 (DE)
Title: Guide rail for shafts
Inventor: POHLE HELMUT
IPC: E21D7/02
Filed: 1986-04-26
Abstract: Serving to guide the cages and counterweights in shafts in underground mining are guide rails in which cushions corresponding to the IPB beam are arranged between the individual guide rails. These cushions consisting of lining pieces are made of a material of limited resilience and permit together with the displaceable mounting at the buntons a movement of the guide rail line in its longitudinal direction without the guide rails being deformed. The service life of guide rails of this type is thereby substantially increased and in addition the assembling and dismantling is facilitated, because the lining pieces made of a material of limited flexibility or resilience can be easily inserted and also easily removed again. These lining pieces are given a shape which prevents them from being displaced in the longitudinal direction of the flanges or in the longitudinal direction of the webs. To this end, the flanges are of stepped design and also of curved design in the area of their outer edges so that there are effective displacement barriers. <IMAGE>
