Abstract: Une source d'energie maremotrice comprend un piston maremoteur (10) constitue par une chambre (19) pourvue de vannes. Le piston (10) entraine une pompe hydraulique (38) pour produire de l'energie electrique par l'intermediaire d'un accumulateur de pression (44) et d'un moteur hydraulique (60). La pompe (38) peut etre verrouille hydrauliquement afin de maintenir le piston maremoteur a la hauteur desire et les vannes (20) de la chambre (19) permettent de remplir celle-ci d'eau ou d'air. Le piston, lorsqu'il est en position basse, a maree basse, et que la chambre est remplie d'air, est ensuite relache et s'eleve de facon controle lorsqu'il est immerge. Il agit alors comme un flotteur immerge et actionne vers le haut le piston de la pompe hydraulique pendant le flux de la maree. Ceci constitue une phase du fonctionnement du dispositif. Lors de la seconde phase de fonctionnement, le piston est verrouille en position haute et la chambre est remplie d'eau lorsque commence le reflux puis relache pour retomber de facon controle. Il agit alors comme un poids suspendu dans l'air apres que le niveau de l'eau se trouve plus bas que le piston, et actionne vers le bas le piston de la pompe hydraulique. Le mouvement ascendant et descendant du piston maremoteur est utilise comme source d'energie.

Abstract: In a coffee machine having rising pipe (32) and flat heater, the flat heater is composed of a boiling disc (10), projecting all round beyond its electric heating element (12), and a base disc (11) of high thermal conductivity and is held by a flexible sealing ring (19) encompassing its edge. Consequently, the heating energy is, to an increased extent, directed towards the centre of the boiling space (20) adjoining the upper side of the flat heater (10, 11), and the region of the coffee machine housing (29) adjoining the edge of the flat heater (10, 11) is protected from a relatively large degree of heating, so that an inexpensively producible one-cup coffee machine having a plastic coffee machine housing of small dimensions can be realised. <IMAGE>

IPC: G06F11/10
Filed: 1979-06-01
Abstract: The invention concerns a method and apparatus for generating error locating and parity check bytes for a block of data bytes each consisting of k bits. 
     The data bytes are presented in series to a data register (10) and fed in parallel to three channels (21, 22 and 23). Each channel has a random access memory including three registers and a memory address circuit operated, under the control of control means (20), to address the three registers cyclically. The first data byte is combined with the output from the first register of each random access memory, the second data byte with the output from the second register and the third byte with the output from the third register whereupon the cycle is repeated. The result is to generate three parity check bytes in the channel (21), three error locating check bytes in channel (22) and three error locating check bytes in channel (23) corresponding respectively to three interleaved subsets of the block of data bytes. The check bytes for each subset of data bytes can be used to locate and correct any one data byte in error in the subset. However, the check bytes of all three subsets taken together can be used to locate and correct an error spanning a series of adjacent data bytes including one data byte from each subset.

Abstract: Reflected light from the record in an optical disc player is directed at a string of photo sensitiv diodes (18). Two adjacent diodes (e.g. 18;, 18 1 + 1 ) of this string of diodes receive light from a selected portion (28) of the track on the disc. The outputs of these two adjacent diodes are summed together to generate the output signal (Vout) for the optical disc player. The outputs of the two diodes are also subtracted from one another to generate a differential signal (V D ) for tracking purposes. The magnitude of this differential signal is a measure of the relative magnitudes of the signals on the two adjacent diodes and therefore is an indication of the position of track laterally of the diodes. When this differential output becomes larger than a preset value, a control logic circuit (26) showing that the two diodes are no longer receiving the reflected light, responds by changing the combination of two adjacent diodes in the string which receive the reflected light, and generate the video output signal and the difference signals.

Abstract: Branching devices for the distribution of light from a supply optical waveguide to conducting optical waveguides in fibre optic communication systems should exhibit low insertion losses even when using graded index fibres, and moreover be of simple structure and production, so that they can be produced in large numbers and inexpensively. According to the invention, this object is achieved in that two optical waveguides (7, 9) are fitted together with their end surfaces which are ground at approximately 45 DEG  and polished and at least one of which is partially mirror-coated, in that in the region of the point of impact on the external diameter of these optical waveguides (7, 9) perpendicular to their axes at least one further optical waveguide (8, 10) impacts and is connected thereto by a transparent adhesive. In this production of such branching devices, a mould with guide trenches (3 to 6) can be used for the positioning of the optical waveguides (7 to 10) (Fig. 1). <IMAGE>
