Patent EP-0278325-A1 (EP)
Inventor: FERNS DEREK
IPC: E02D29/14
Filed: 1988-01-27
Abstract: The frame (1) is composed of a pipe section (2) and a marginal part (3) arranged on the outside of the pipe section (2) and projecting outwards. Provided on the inside of the pipe section (2) are projections (4) on which a cover or grating can be supported. The marginal part (3) is designed as a cohesive collar which projects horizontally outwards. The marginal part (3) is arranged at a height (h) below the top margin (8), the height (h) being one third to one half of the overall height (H) of the pipe section (2). Owing to the fact that the marginal part (3) is arranged at a distance from the top margin (8) of the pipe section (2), it will be surrounded on all sides by the material of the roadway paving when the frame (1) is installed, as a result of which the frame (1) is solidly connected to the ground material and cannot be substantially displaced by the traffic flow.

Title: Drive unit for electrically driven remote-controlled mirror
Inventor: YOSHIDA NORIO
IPC: B60R1/072
Filed: 1988-11-23
Abstract: In a drive unit for an electric remote control mirror, a pair of screw rods (16) for slanting the mirror (10) around horizontal and vertical axes is disposed movably forwardly and backwardly within the drive casing (14). Within the drive casing (14), there is disposed a pair of drive motors (20), of which the rotations are transmitted through a reduction gear group (52) to a pair of rota­tion members (30), of which the rotations are converted into forward and backward movements of the pair of screw rods (16). Each of the rotation members (30) is composed of a shaft (36) having a pair of arm members (34) with a screw thread which is in mesh with a screw thread (24) formed on the inner circumference of the screw rod (16), a hollow cylindrical rotation body (38) having a gear (46) in mesh with the reduction gear group (52) and a space (18) in which the screw rod (16) is placed, and a plurality of connection members (40) extending radially and which provide a connection between the base of the shaft (36) and the lower end of the rotation body (38), each of the connection members (40) being formed relatively thin so that when the shaft (36) is applied with a force from the screw rod (16), the connection member (40) is resiliently deformable. When each screw rod (16) is moved forwardly or backwardly, the shaft (36) is applied with a force from the screw rod (16), but since the plural connec­tion members (40) are resiliently deformed, the shaft (36) can be slanted axially so that each screw rod (16) can positively follow up with the pivoting of the mirror.

Abstract: Electrodes poreuses destinées à être utilisées dans des piles à combustibles et autres cellules électrochimiques. Ces électrodes présentent une couche catalytiquement active sur un substrat poreux conducteur, la couche active étant dérivée de matériaux non nobles. Le contenu de la couche catalytiquement active est plus faible qu'auparavant en ce qui concerne le poids du catalyseur par unité de surface géométrique de l'électrode, et les caractéristiques de fonctionnement de l'électrode se comparent avantageusement avec celles des électrodes de la technique antérieure utilisant des catalyseurs en métaux nobles, les nouvelles électrodes présentant un coût considérablement plus faible. On peut fabriquer ces électrodes par imprégnation d'un substrat poreux conducteur avec une solution de sel métallique, suivie par la formation par réaction chimique ou thermique de la couche active; ou par le mélange du matériau catalytiquement actif avec le matériau du substrat poreux conducteur, suivi par la fabrication de l'électrode; ou encore par le dépôt pyrolytique de carbone en phase gazeuse sur un substrat poreux conducteur, à haute température dans une atmosphère gazeuse. L'électrode peut présenter un collecteur de courant métallique poreux, ainsi qu'une couche de diffusion de gaz. Lorsqu'on utilise cette électrode comme anode de pile à combustible, on introduit également un petite quantité d'un métal noble dans la couche catalytiquement active. Ces électrodes poreuses peuvent également être utilisées dans des éléments primaires ou secondaires de piles alcalines.

The rotary drilling tool (2; 102; 202; 302; 402; 502; 602; 702) has a housing (3) in which a deep-hole motor (13, 14) is arranged and a cutter shaft (16) connected to the rotor (14) of the deep-hole motor (13, 14) and carrying a rotary drill bit (21) at its end projecting out of the housing (3) is mounted. Close to the rotary drill bit (21), the rotary drilling tool (2; 102; 202; 302; 402; 502; 602; 702) has a first stabilisation point (22), and provided at a distance above the latter is at least one second stabilisation point (25). During operation of the rotary drilling tool (2; 102; 202; 302; 402; 502; 602; 702) for drilling a drill hole (1) with a curved centre line, the rotary axis (19) of the cutter shaft (16) and an imaginary bottom extension of the part of the main tool axis (27) running at the level of the second stabilisation point (25) enclose a deflection angle ( alpha ) opening towards the rotary drill bit (21). In this arrangement, the rotary drilling tool (2; 102; 202; 302; 402; 502; 602; 702) is of a design which, during directional drilling of the rotary axis (19) of the cutter shaft (16), predetermines alignment with an imaginary straight connecting line (28) between the curve centre and the base point (26) of the curved centre line of a drill hole (1), to be drilled with the rotary drilling tool (2; 102; 202; 302; 402; 502; 602; 702), at a setting angle ( beta ) of 90 DEG  as an upper limit value.
