Title: Cross groove constant velocity joint having fixed center
Inventor: WARNKE JAMES W
IPC: F16D3/227
Filed: 1992-06-26
Abstract: ABSTRACT OF THE DISCLOSURE A cross groove variety of constant velocity universal joint includes an inner race having a plurality of grooves formed in an outer surface thereof and an outer race having a plurality of grooves formed in an inner surface thereof. For each pair of associated inner and outer race grooves, the inner race groove is inclined in one direction relative to the rotational axis of the joint, while the outer race groove is inclined in the opposite direction.  A ball is disposed in each of the associated inner and outer race grooves for providing a driving connection between the inner and outer races.  A cage is provided for retaining the balls in the grooves.  In a first embodiment, mating spherical surfaces are formed on the inner surface of the outer race and the outer surface of the cage.  The engagement of these spherical surfaces prevents the center of the joint from moving axially during use.  In a second embodiment, mating spherical surfaces are formed on the inner surface of the cage and the outer surface of the inner race for the same purpose.

IPC: H01P5/18
Filed: 1992-07-14
Abstract: P/8635/MSS/ep ABSTRACT                MULTI-PORT MICROWAVE COUPLER     A  multi-port microwave coupler has eight input  ports In 1, In  2, In 3, In 4, In 5, In 6, In 7 and In 8 and eight output ports Out 1, Out 2, Out 3, Out 4, Out 5, Out 6, Out 7 and Out  8  and  is  synthesised from twelve 2  X  2  hybrid couplers  which are arranged as three sets, that is a  first set A,  B,  C and D, a second set E, F, G and H and a  third set I,  J, K and L.  A first group of transmission lines 11, 12, 13,  14,  15, 16, 17 and 18 interconnect the  first  and second  sets  of  hybrid  couplers, and a  second  group  of transmission  lines  21,  22,  23, 24, 25, 26,  27,  and  28 interconnect  the second and third sets of hybrid  couplers.          The first  set of hybrid couplers are arranged substantially in a row  in  the sequence first, second, fourth and  third, that is  A, B, D and C with one half of the second and third sets E,  G, I and J arranged on one side of the row and with the other half of the second and third sets F, H, K and L on the other  side of the row.  In this manner all  cross-overs in the  first  and second groups of transmission  lines  are avoided  thereby  providing a planar realisation of a 8 X  8 multi-port  microwave  coupler, Instead of the first set  of P/8635/MSS/ep hybrid couplers being arranged in a row, it is also possible to achieve  a similar result by arranging the second set  of hybrid  couplers  in  a  row  in  the  same  sequence.   The invention is of application to higher order n x n multi-port microwave couplers where n = 2(2+p) and p is a whole number.     Figure 5

Abstract: : Pour restituer un signal d'horloge qui a servi à coder des signaux transmis sur une voie de transmission, on détecte avec précision les instants de transition de ces signaux par une analyse d'une série d'échantillons prélevés sur les signaux pendant au moins une fraction de la période d'horloge. Un dispositif détermine d'abord les écarts des différents échantillons prélevés les uns par rapport aux autres. La comparaison de la configuration d'écarts obtenue avec des configurations-types déterminées au préalable, permet d'évaluer la position de la fenêtre de temps où l'échantillonnage a eu lieu par rapport à la fraction de période analysée et donc de décider si cette fenêtre est correctement centrée. Dans le cas contraire, on agit sur une horloge locale pour la resynchroniser. Application dans les transmissions de données de diagraphies ou de données sismiques par exemple.

Title: Brewing apparatus for a coffee machine
Inventor: LUESSI ANDRE
IPC: A47J31/24
Filed: 1992-07-28
Abstract: A brewing unit has a brewing cylinder (1) with a cylindrical bore (2) and two plungers (3, 4). The brewing cylinder (1) and the plungers (3, 4) are arranged so as to be displaceable relative to one another. In a brewing position, the brewing cylinder (1) and the two plungers (3, 4) located inside the latter form a brewing chamber (5) in order to brew ground coffee located therein by adding pressurised water. The latter is fed to the brewing chamber (5) via a connection nipple (18) and via a through-bore which extends through the wall of the brewing cylinder (1) into a circular gap (14) formed between a sealing ring (11) and the end face (13) of the second plunger (4) facing the brewing chamber (5). The coffee is delivered via a filter (32), a pipe (34) and a further connection nipple (35). Due to the arrangement of the gap (14), the end side (13) of the second plunger (4) can be constructed without a filter. The feeding of pressurised water to the gap (14) causes a self-cleaning effect therein. Due to the construction of the end face (13) of the second plunger (4) without a filter, not only can a part subject to wear be eliminated, but a more cost-effective production of the brewing unit can also be implemented. <IMAGE>

IPC: H04J14/08
Filed: 1993-04-14
Abstract: The high transmission capacity of an optical transmission path (about 200,000 km Mbit/s) is used, among others, to couple several data sources and data sinks to an optical waveguide. The task of the invention is to ensure the coupling in and out of several data streams to or from any path section of a (predetermined) optical transmission path. This task is fulfilled by a device for the parallel-serial conversion, and a device for the serial-parallel conversion of the data streams to the optical transmission path. The coupling in and out of the individual data streams is performed by optical modulators or optical expanders, which are incorporated into the optical transmission path. Several data streams are parallel-serial converted by means of additional incorporated optical time delay elements, which ensure the bit interlacing of the data streams (bit-interleaved).
