Filed: 1993-09-30
Abstract: A planar solid electrolyte fuel cell contains a plurality of separators (11) and electrical insulators (21), which, together with associated junction sections of the separators, are alternately placed one on top of the other. Each separator (11) has a junction section (40) in its centre, which is provided with two gas introduction holes (4, 5), and a reaction section. The reaction section has guide walls (19A, 19B), which surround the junction section and serve for the reaction gases to flow through. Standard cells, which are located on porous substrates, are each in the form of an annular plate with an individual centre hole. The reaction sections of the separators (11) enclose between them, in the manner of a sandwich, the standard cells (12). Gas sealing parts (6A) are provided around the gas introduction holes (4, 5), and gas sealing parts (6B) are additionally provided between the reaction sections of the separators (11) and inner circumferential sections of the standard cells (12). <IMAGE>

Patent DE-4403235-A1 (DE)
Title: Method of tracing or following electrical conductors
Inventor: GEORGI MARTIN
IPC: G01V3/11
Filed: 1994-02-03
Abstract: The method involves using an AC power supply (c), with two poles, and an adjustable capacitive sensor (e). A low frequency signal in the range 10 to 50 kHz is fed into one end of the conductor being sought by the supply via one pole. Only a single wire or screen is required to enable the signal to be fed in. The remaining pole (d) of the signal generator is earthed. The conductor being sought is detected by comparing the intensity of radiated electrical fields using the sensor. The sensor finds the strongest electrical signal in the input frequency range and gives a visual indication via a controlled lamp.

Patent DE-4422032-A1 (DE)
Title: Stiffened fuel element
Inventor: STEINKE ALEXANDER ING GRAD
IPC: G21C3/33
Filed: 1994-06-23
Abstract: In order to reduce bending of the fuel rods of a fuel element, the bending being produced as a result of loading during reactor operation, some positions of fuel rods are substituted by fuel-free, inactive supporting rods (22). These supporting rods are in each case separated from the edge of the fuel element (and advantageously also from neighbouring control rod guide tubes (21)) by a position which is occupied by a fuel rod. In the case of fuel elements having control rod guide tubes, these advantageously have a polygonal outer cross-section - in the case of cylindrical internal surfaces that is to say corners which form a mechanical reinforcement - with the result that actual supporting rods can be dispensed with. <IMAGE>

Title: Stable binding for stack of articles
Inventor: HALTER HARTMUT DIPL ING
IPC: B29C61/00
Filed: 1994-08-09
Abstract: A process is claimed for holding together a stack of articles by means of a strip of plastic film made of memory polymer (I), so as to form a stable pack of given size in the winding direction. The initial length of strip (I) in the unstretched state (L1) is 1/2-2/3 times the circumference (U) of the entire pack; (I) is first stretched to a length (L2) greater than (U) and then wound round the stack, and the stabilising effect of the wrapping is achieved by cold shrinkage to give an elongation of at least 50 % in the strip, as defined by the amt. of wrap-around.
Patent DE-4430890-A1 (DE)
Inventor: JOERN FRIEDRICH-W
IPC: B22D25/02
Filed: 1994-08-31
Abstract: The invention concerns improvements to a method for producing cast-iron parts with a section having an outer contour which is helically symmetrical to an axis of symmetry such that these parts can be more simply produced and hence more economically. According to the invention, a pattern (84) comprising the section (16) with a helically symmetrical outer contour is shaped so as to produce a casting mould body (50) which surrounds this section azimuthally to the axis of symmetry and in an enclosed manner, and a casting (10), which corresponds to the part to be manufactured, is produced with this casting mould body (50) in a casting mould (44) by tempering which leads to solidification of the cast-iron melt shell.

Abstract: Capteur pour la mesure électrique de forces, de contraintes mécaniques ou assimilées, qui sont transformées par le capteur en un champ de contrainte normale et ensuite en une variation de la résistance électrique. On applique, perpendiculairement au champ de contrainte normale sigmagamma, un élément de mesure piézorésistif (17) comportant au moins une couche de matériau résistif, dont la constante C est choisie de manière à ce que la charge mécanique de l'élément de mesure n'affecte pas la mesure par suite de l'expansion d'un support (1). Les couches résistives peuvent être des échantillons (M1, M2) qui se croisent et sont mutuellement superposés. Des éléments de surface (13) sont ainsi formés ayant la même contenance, qui suivent entièrement les expansions mutuellement perpendiculaires (epsilonx, epsilony) du support (1). Pour compenser les effets de perturbations, un élément de compensation (18) correspondant à l'élément de mesure (17) est disposé à l'extérieur du champ de contrainte normale.
Patent WO-8602128-A1 (WO)
Title: Pinion motor
Inventor: RUSTIGE HAYNO
IPC: F03C2/08
Filed: 1985-09-26
Abstract: The pinion motor has two pinions which engage on their external sides (14, 15) the shafts of the pinions being supported on both sides in bearings (18 to 21). The bearing elements (19, 21) on one side of the pinions are designed with a lesser thickness than those on the other side. They are pressed against the lateral surfaces of the pinions by pressure regions (26, 27). The application forces of the thinner bearing elements (19, 21) against the inner wall (11) of the housing (10) must not be too large, since otherwise the starting-up behaviour of the pinion motor is impaired. These application forces are, inter alia, proportioned to the thickness of the bearing elements; the bearing elements on which the pressure regions are provided are not so thick.
