Patent EP-0353543-A1 (EP)
Inventor: SEIDL JIRI
IPC: F01L1/14
Filed: 1989-07-19
Abstract: In a valve operating mechanism for internal-combustion engines, a control shaft (3) with a control cam (4) for actuating a valve (6) acts on a tappet (5) which interacts with the control cam (4) by means of an arched sliding track (8). To achieve an ample torque curve at low speeds of the internal-combustion engine and with this an acceptable power level in the upper speed range, it is proposed for the purpose of the advantageous dimensioning of the interacting valve gear elements that the control cam (4) for an inlet valve have a main cam of at most 240 DEG  crankshaft angle with a cam or valve stroke of at least 10 mm, the sliding track (8) of the tappet being designed with a roll radius of between 50 and 80 mm. <IMAGE>

Abstract: The apparatus comprises a table with driven balls (3), at the centre of which is located a turntable (2) with driven balls (18). The balls (18) are driven by setting in motion a linear-movement member consisting of two endless belts (22 and 23), the upper face of which is in contact with the lower part of each of the balls (18). The movement of the turntable (2) is obtained by means of a geared motor (37) mounted on the axle (36) of the turntable (2), and the vertical movement of the said turntable is generated by a pneumatic cylinder (82). 
<??>The apparatus is used in the sector of the turning and orientation of stacks of articles, such as box blanks used in the box-making industry.

IPC: F16F1/36
Filed: 1989-12-12
Abstract: The invention relates to a flat plate mount 1 consisting of a rubber strip or plate material through which pass hollow channels 3 and cavities 2. The cavities 2 and hollow channels 3 are all located in a single surface which is at least essentially parallel or complementary in form to the main surface of the flat material, in each case only one hollow channel 3 passing through each cavity 2. The hollow channels 3 are open at least on one side and have an unobstructed cross-sectional area which is at least a quarter of the maximum cross-sectional area of the cavities 2 through which this hollow channel 3 passes. The hollow channels 3 can run such that they are not parallel to at least one longitudinal axis or to the longitudinal axis of the flat plate mount, that is to say, for example, that they form an angle of 90 or 45 DEG  therewith, while they are either parallel or not parallel to one another. However, in the case of polygonal or circular flat plate mounts, they can also be aligned running radially to the centre point, without intersecting or touching in the centre, that is to say also open only on one side. An opening 6, constructed in the centre of the flat plate mounts 1 according to the invention, has no adverse effect on the mounting characteristics but offers numerous design possibilities. Overall, a soft springing of heavy loads, free of any kinking effect, is produced, acoustic decoupling being achieved to a large extent.

Title: Ceramic tile
Inventor: LEGARDA ZARAGUETA JUAN JOSE C
IPC: E04D1/16
Filed: 1989-10-09
Abstract: A ceramic tile which is rec­tangular in shape has an opening (12) near its ends. The corners have grooves (15), while at the other end, it is cut off to form a skirt. The tile is obtained by means of moulding of ceramic stoneware in two pressings, one of four and six times less than the other. Steps (17,21) are created during the first pressing, around the opening and peripherally all along the edge of the tile. The tile has grooves (18) on its parallel sides which form the casing for the retention heads, from which the tiles hang when they are placed on the roof. The entire piece is shaped in the course of the second pressing which maintains the descend­ing steps (21,1F) of the grooves and determines in the side not seen of the part, an orthogonal striation (16) which is above the step (17) and the grooves (18), whose length defines the maximum and mini­mum overlapping of the tile. The outer side (19) of the tile and the borders (20) are glazed with a synterized enamel.

Abstract: A hand-held device for recording photometric data on a printing material has a measuring head which can be moved out of a housing into a measuring position. The measuring head is mounted, together with the associated optical components, on a measuring carriage (15) which can be moved along the base (6) of the housing between a rest position and a measuring position with the aid of a drive motor (31). The drive motor (31) drives a drive actuator (37), on the one hand, and a grid axis (30) for a monochrometer, on the other hand, via a gear system (33). The drive actuator (37) has a slotted gear (40, 41) and a locking device (42 to 51) which locks the measuring carriage (15) accurately in the measuring position. The drive motor (31) essentially serves to move the measuring carriage (15) until the locking operation takes place and thereafter to rotate the grid axis (30).

Title: Dispositifs optiques a cristaux liquides presentant un gradient controle d'ordre en surface
Inventor: DURAND GEORGES ANTOINE
IPC: G02F1/1337
Filed: 1988-12-16
Abstract: La présente invention concerne le domaine des dispositifs à cristaux liquides. Selon l'invention une rugosité de l'ordre de grandeur moléculaire du cristal liquide est définie sur l'une au moins des plaques. Cette rugosité entraîne un gradient d'ordre qui induit une polarisation ordoélectrique associée à un champ dépolarisant qui tend à forcer les molécules de cristal liquide selon une orientation oblique par rapport à la plaque. Le contrôle de l'épaisseur et de la direction préférentielle de rugosité permet de plus de contrôler l'orientation oblique psi et l'orientation azimutale phi des molécules dans une plage continue de variation. La présente invention permet également de réaliser des interfaces non polaires pour les afficheurs à smectique C* ferroélectrique.
