Patent DE-3212073-A1 (DE)
Title: Tunable radio-frequency generator with almost temperature-independent frequency
Inventor: ROSKE ERICH
IPC: H01F27/36
Filed: 1982-04-01
Abstract: The radio-frequency generator contains a variometer with rotatable short-circuit winding and oscillating circuit. Coil former and rotor consist of a dimensionally stable insulating material with the same thermal expansion, for example of glass or special steatite. The screen casing and lid optionally consist of a different metallised insulating material having the same mutual thermal expansion, for example of moulded laminated material. The rectangular lids form the reference edges for the assembly of the individual parts fabricated with coarse dimensional tolerance. During the manufacturing process, the individual parts are positioned by gauges and differences in dimensions are equalised by bonding and soldering joints and interposition of spacers. During the calibration process, the centre frequency pushed into the upper tolerance range is shifted to the lower tolerance range by adding small capacitances with negative temperature coefficients, the temperature coefficient of the frequency being calibrated towards zero. The technical advance consists in a more inexpensive manufacturing and calibration process.

Title: Casks for the storage of radioactive substances having a ceramic corrosion-protective layer surrounding the substances
Inventor: BIENEK HEINZ ING GRAD
IPC: G21F5/005
Filed: 1982-04-03
Abstract: In the case of casks for the storage of radioactive substances, in particular ultimate storage, the radioactive substances are surrounded with respect to the storage space by a ceramic corrosion-protective layer, the starting material of which can be processed as a free-flowing mass. In order to avoid high temperatures and high pressures in processing, it is proposed according to the invention that the free-flowing mass is a ceramic-based casting compound (M) which cures pressurelessly and at low temperature. In this case it is possible for the radioactive substances, in fine-particled or piece form, to be mixed with the casting compound and poured into a mould for curing. In the case of a cask which has a corrosion-protective container (4, 12, 12a, 12b) with a receiving space receiving the radioactive substances (7, 8), according to the invention the radioactive substances are enclosed in the receiving space by the casting compound (M) which cures pressurelessly and at low temperature, to be precise they are enclosed directly or with a further, preferably metallic, container in between. <IMAGE>

Title: Covering for frying pans or similar vessels, having a filter surface which is permeable to steam
Inventor: VOSSEN FRANZ
IPC: A47J37/10
Filed: 1982-05-06
Abstract: A covering for frying pans or similar vessels, having a filter surface which is permeable to steam and is made of a fibrous material, in particular of filter paper, having a bearing ring which surrounds said filter surface, is cut with spoke-type radial arms from a disc of cardboard material or the like, and runs parallel to the plane of the filter paper or the like which is connected non-detachably to said ring and the radial arms, is to be designed in such a way that, without dispensing with the simplicity of production and handling, deformation through the effect of heat is kept at bay and dimensional stability of the covering is maintained even when a large amount of moisture is produced. This is achieved in that the radial arms (7) of a width (n) are weakened in their cross-section by at least one incision (30) starting from one of their edges, and the bonded connection between the radial arm and the filter surface (20) is reduced in the region of cross-sectional weakening. In this case, at least two incisions (30) are to be provided in the radial arm (7), each of which incisions starts from one side edge, and which run approximately parallel to each other. <IMAGE>

Title: Arrangement for providing suspension for bogey locomotives
Inventor: SCHWAERZLER PETER DIPL ING
IPC: B61F5/14
Filed: 1982-05-08
Abstract: When fast bogey locomotives travel around bends it is important that the bogey adopts an approximately radial position with respect to the bend in the track since otherwise the wear on the wheel profiles increases. Proposals for the special arrangement of the customary springs and/or of additional springs are made so that even in the case of transverse deflection and/or rocking deflection of the locomotive superstructure the transverse forces acting on the bogey wheels on the outside of the bend are of approximately the same size.
Patent DE-3219151-A1 (DE)
Title: Clamping device
IPC: B25B5/08
Filed: 1982-05-21
Abstract: In the case of a clamping device having two clamping blocks with bearing surfaces arranged in a common plane, the outer end faces (25, 26), facing away from one another, of the clamping blocks (1, 2) are inclined upwardly inwards, so that the distance between their edges delimiting the bearing surface (3) is greater than the distance at their edges (27, 28) remote from the bearing surface. The clamping blocks are spanned by a yoke (10) which serves as clamping member, is supported on the clamping blocks via compression springs (13, 14) and has at its ends projections (29, 30) which face the clamping blocks and whose inner faces have the same inclination as the outer end faces (25, 26) of the bearing blocks. By means of a screw clamp or the like, the yoke can be pressed onto the clamping blocks so that the clamping blocks, on the one hand, are pressed via the springs onto the surface of the workpieces and, on the other hand, are brought closer to one another via the oblique faces (27, 28) of the yoke and the oblique end faces (25, 26), in which process they carry along and press together the workpieces (41, 42). <IMAGE>

Title: Process for granulating chemically produced gypsum and apparatus for carrying out the process
Inventor: HEYN KLAUS DR DIPL PHYS
IPC: C01F11/46
Filed: 1982-06-18
Abstract: In certain chemical processes, gypsum is formed in fine-particle form. Previously, the gypsum after dehydration by filtration always needed to be dried before the fine-particle gypsum could be compacted to give granules. To simplify the previous process, according to the invention, the gypsum is filtered to a moisture content of 5-15% by weight and the gypsum crystals are then broken in the compact-forming process perpendicular to their preferential direction by a pressing/shearing process. The pressing/shearing process is preferably effected by pressing the gypsum through an opening. This opening can in turn preferably be present in a grind-and-mix press or in an extrusion press. Preferably, at least one section of the opening narrows conically as viewed in the pressing direction. <IMAGE>

Title: Hand-held drill with a drilling template for setting dowel holes
Inventor: HUBER GEORG
IPC: B23B47/28
Filed: 1983-02-16
Abstract: For setting dowel holes in pieces of wood to be joined to one another by means of a drilling template on a hand-held drill, the positioning of the lateral spacing of the dowel holes in the two pieces of wood from the same reference surface presents difficulties: when drilling the second dowel hole, the drilling template must namely be turned through 180 DEG  with respect to the reference surface for the lateral spacing; therefore, the usual side stops, firmly connected to drilling templates, cannot be used. Therefore, in the case of the invention the side stop (22) can be removed from the drilling template (2) and connected to it so as to protrude to the left or right. For this purpose, between drilling template (2) and side stop (22) there are provided connecting means (204; 2210) which are arranged symmetrically with respect to a plane of symmetry (M) running through the drill axis (B). <IMAGE>

Title: System for transport of solids in pipelines by means of liquid or gaseous transport media
Inventor: BOJAK KURT DIPL ING
IPC: B65G51/02
Filed: 1983-04-02
Abstract: For transport in pipelines using liquid or gaseous transport media, for example water or air, the solids occurring in lump form in extraction or production, for example coal or ore, are first comminuted and then combined to form compact material units of the same kind with easily transported shapes, for example as spheres or cylindrical bodies, as described in the main Patent Application P 3307902. Additional technical and economic advantages result from a systematically alternating sequence of material units in the pipe, preferably cylindrical material units with good shear effect and between them spherical units with relatively low transport resistance following sucessively at distances. By the use of cylindrical bodies with good shear effect in the form of preshaped material units or specially constructed shear elements, advantageous possibilities also result for the pipe transport of irregularly lumpy material or of fine-grained material in a suspension.
