Title: Teaching and amusement apparatus
IPC: G09B7/06
Filed: 1988-02-05
Granted: 1992-04-15
Abstract: Known teaching and amusement apparatus comprises a self-contained electronic "pen" which is used in conjunction with specially printed material to provide an interactive system e.g. in the form of a worksheet or book having question and answer areas. The "pen" used senses differences in the infra-red radiation properties of the answer areas to indicate audibly whether a correct or an incorrect answer has been selected. The invention relates to an improved "pen" (10) which operates in an active mode and a programming mode. A switch (12) changes the mode of the "pen". In the programming mode, the "pen" is programmed to operate according to the printed material on which it is to be used. The "pen" (10) further includes a visual display (13) for indicating whether a correct or incorrect answer has been given.

Patent EP-0290422-B1 (EP)
IPC: E04G21/12
Filed: 1988-05-06
Granted: 1992-02-19
Abstract: The invention consists of a method for prestressing structural elements characterised by establishing, in a base element prone to instability, an arbitrary and predetermined stress field of direction opposite that to which the element will be subjected in use (fig. 2).   This stress field is maintained, as far as possible or necessary, by solidly attaching suitably sized reinforcing elements of appropriate elastic limit. The complete element is then located in the following situation (fig. 3):  - low tension in the additional elements - persistence, in the base element, of a residual tensile field of direction opposite that which will be caused by the principal actions of use. This prestressing is carried out on a special bench (fig. 1) which enables any desired linear stress field to be created. This procedure enables beams to be constructed where it is possible systematically to use high strength materials and to exploit better the capability of lower strength materials by considerably extending their region of admissible stress variation, principally for the parts prone to instability by warping or buckling (fig. 4). <IMAGE>

Abstract: Appareil et procédé d'extraction de fluide à partir d'une bande fibreuse (W), ledit appareil (10) comportant un élément de presse (12) ainsi qu'une couverture (14) coopérant avec l'élément de presse (12), entre lesquels est définie une partie de pressage allongée (16), de sorte que la bande (W) est pressée entre l'élément de presse (12) et la coverture (14) pendant le passage à travers la partie de pressage (16). Un patin allongé (18) pousse la couverture (14) vers l'élément de presse (12), de sorte que lorsque la bande (W) passe à travers la partie de pressage (16), du fluide est extrait de la bande (W). Un système de chauffage (22) est disposé adjacent à l'élément de presse (12), afin de transférer de la chaleur à la bande (W), de sorte que lorsque celle-ci (W) passe à travers la partie de pressage (16), ladite bande (W) est soumise pendant une période prolongée à une pression et à une température augmentées, de sorte que la vapeur d'eau produite dans la partie de pressage (16) pendant le passage à travers celle-ci (16) contraint le fluide en phase liquide à sortir de la bande. L'élément de presse (12) définit une surface de pressage (24) poreuse, ce qui empêche le décollement inter-laminaire de la bande.

According to the invention, the case comprises a box (1) having substantially a parallelpipedal shape, and being provided with an opening (2) for a cassette to be inserted therethrough into its box, which is formed in at least one of the box sides, in such a manner as to leave at least two wall portions (3, 4) which extend from two opposite end-side walls (5, 6) of box (1), and which are longer than the extent of cassette (15) in the direction in which a cassette is inserted into its box. A movable abutment member (7, 7 min ) is provided in the region of one of the two end-side wall portions (3, 4) of the box sides, and is caused to cooperate with one end-side edge of cassette (15), the said movable abutment member (7, 7 min ) being pushed by spring means (10, 10 min ) into its abutting active position, or vice-versa. By a locking and unlocking device (11) the movable abutment member (7, 7 min ) is moved from the said abutting active position into a withdrwan inactive position. The cassette (15) is inserted into its case in an inclined condition, and with the movable abutment member (7, 7 min ) in its inactive position, the cassette is so shifted as to be engaged under the end-side wall portion (4) which is associated with the movable abutment member (7, 7 min ), by being passed thereover, whereupon the cassette (15) is moved backward so as to be engaged also under the opposite end-side wall portion (3), thus uncovering the movable abutment mem ber (7, 7 min ) which is moved into its active position, in which it is caused to cooperate with the associated end-side edge of cassette (15), whereby any such shiftement of cassette (15) is prevented, that may be apt to disengage the same for the two end-side wall portions (3, 4).

Abstract: The apparatus for providing a passage in a sealing member, in particular a stopper of a container of a fluid sample, by using a penetrating sleeve defining the passage, comprises a displaceable sticking tool. The latter comprises a spike with a pointed end. During operation the spike is inserted into the sleeve and brought into a position in which its pointed end protrudes through the front end of the sleeve. The spike together with the sleeve are then stuck through the sealing member. Subsequently, the spike is pulled out of the sleeve, while the sleeve is left inside the sealing member. In this way, the sleeve may be inserted into the sealing member along a predetermined path, while any cutting or shearing of particles off the sealing member may be avoided.

Abstract: The invention relates to a spark-erosion electrode which consists of a conductive ceramic material, and to a method for manufacturing said electrode. In particular, said electrode is manufactured by introducing the slip-type ceramic material into a porous female tool, a body forming the electrode being produced by removing liquid. Said body is then fired in a firing furnace. Electrodes manufactured in this way are extremely temperature-resistant, with the result that a high spark-erosion voltage can be applied. Compared with the manufacture of known metal electrodes, the manufacturing method is very simple and cheap because no cutting operations are necessary. <IMAGE>

Abstract: The invention relates to a screw-in acetabular prosthesis (1) of spherical geometry with a special thread for cementless implantation, and to a method for its manufacture. The special thread follows in its pattern the spherical circumference formed by the nominal diameter of the cup (1) and is almost completely adapted in its base to this spherical circumference by virtue of the fact that the layout of the thread base is adapted to a very great extent to the spherical outer contour of the acetabular prosthesis (1) by means of strip-shaped part surfaces which are divided into steps in terms of angle and which extend parallel to one another and obliquely relative to the layout of the thread base. The special thread is cut according to the invention by machining with a number of tools, with different cutting edge angles in relation to the thread base (6, 7, 8), and on different paths. Compared to conventional spherical screw-in cups, the thread configuration according to the invention, by means of the freely available thread tooth depth, affords a substantially better primary fixation upon implantation and at the same time considerably reduces the risk of loosening by virtue of the fact that, as a result of the complete contact between the surface of the cup and the bone over a large area, only low specific forces act on the bone bed. <IMAGE>
