Title: Safety valve which closes on tilting of tank - has valve, biased closed, but held open by weight of ball, which rolls out of contact to release valve on tilting
IPC: F16K17/36
Filed: 1976-05-19
Abstract: A sleeve (3) is seal-fitted underneath an orifice or vent hole (2) on the upper wall (1) of the tank. At the bottom of the sleeve is a dome shaped perforated wall (5) with a central orifice (6), which is filled in the vertical position, by a heavy ball (4) which can move freely in the internal chamber (7) of the sleeve. The ball holds down, in the open position, a valve (12), the cylindrical head of which is under pressure from an internal spring (14) which abuts onto a partition wall (9). When the tank is tilted the ball rolls away from the central orifice allowing the spring to push the valve away from the partition wall and against the bevelled edges (16) of a muff (15), thus isolating the vent hole from the rest of the tank.

Title: Memoire
IPC: G11B20/10
Filed: 1977-02-25
Abstract: L'invention procure un système simple pour détecter une catégorie déterminée d'erreurs de lecture lors de l'emploi d'une mémoire à disque(s). Chacune des pistes concentriques sur une surface de disque offre la place nécessaire pour un nombre invariable de secteurs. Sur une première position angulaire du disque se situe l'indication d'angle de debut Chaque secteur commence par une indication de marquage, qui est détectée et convertie en une impulsion de comptage par secteur, fournie à un compteur. La piste en question ayant été << présentée >> à la tête de lecture, les impulsions de comptage sont comptees depuis de la première détection de l'angle de début Si lors de la première détection suivante de cette indication d'angle, on n'a pas encore trouvé le secteur d'information recherché cependant qu'en outre le compteur indique un solde de comptage inférieur audit nombre invariable, le secteur d'information en question n'est pas détectable de façon distincte. Il est alors engendré un signal d'erreur, tandis qu'ensuite sont prises des mesures adéquates qui en partie sont déterminées par l'identité du secteur d'information << raté >>. De plus, le solde de comptage trop faible fournit une indication au sujet de la nature de l'erreur, de sorte que lesdites mesures peuvent être directement plus spécifiques et qu'une opération de rétablissement est possible sous la commande d'un programme à durée relativement courte Application aux télécommunications.

Title: Semiconductors, such as bipolar transistors - with amorphous layers locally crystallised by e.g. laser to reduce number of mfg. operations
IPC: H01L29/73
Filed: 1977-05-04
Abstract: A device is made contg. a p-n junction. A substrate(1) is coated with a uniformly doped amorphous semiconductor layer(2) of one conductivity type(a); and an energy beam(x) is used for local conversion of parts of layer(2) into polycrystalline zones(2z). A second layer(3) of uniformly doped amorphous semiconductor, with opposite conductivity(b), is then applied on top of layer(2), and beam(x) is used for the local formation of polycrystalline zones(3z). Beam(x) is pref. a laser providing photocrystallisation; or an electron beam; ultraviolet rays; or X-rays. The amorphous layers(2,3) are pref. Si; or Ge, Se, or Se alloys. The process is pref. used to mfr. a transistor, where zones(2z) form the collector; zones(3z) form the base; and a third amorphous layer(4) of conductivity(a) has zones (4z) which are the emitter. A pronounced redn. in the number of mfg. operations is achieved, because a programmed laser or electron beam can trace the circuits required, the remaining amorphous regions forming insulating zones between different elements in an integrated logic circuit.

Title: Energy generation system using fluid - uses fan to create pressure drop which generates more power
IPC: F03D1/04
Filed: 1977-07-07
Abstract: A propeller or fan is mounted in a circular duct (2) which tapers to a smaller diameter (2b) downstream from the fan. This reduction in duct diameter causes an increase in the linear velocity of the air flowing through the duct. This increase in velocity reduces the pressure inside the duct below that of the ambient air. Additional air is sucked into the zone (5), which lies ahead of the duct (2), through the annular ducts (6, 7, 8). The energy of the total mass of air flowing in the duct downstream of the annular ducts (6, 7, 8) is increased. The outward flow of air can be used to generate a surplus of power.

Title: Dialyser having pairs of membranes between supporting plates - in which plates have rows of ribs providing large number of contact points with membranes
IPC: A61M1/22
Filed: 1977-10-13
Abstract: Dialyser comprises a stack of alternate plates and pairs of dialysis membranes providing passages for the dialysate between a plate and an adjacent membrane, and for the liq. to be purified between two membranes. End plates seal the stack. On each face of the intermediate plates and the inwardly-directed faces of the end plates rows of short parallel ribs are provided, sepd. by lines of transverse ribs. The spacing of the first and last rows of ribs from the corresp. adjacent edges of the plate is such that when the plates are turned through 180 degrees relative to neighbouring plates the rows of ribs are staggered in contact by about half the length of the ribs in a row. The ribs provide a large number of points of contact with the membranes, liniting the flow of the liq. to be purified to a film between the membranes. This improves the efficiency of the dialysis. The dialyser may be used for blood dialysis as a disposable unit, and the volume of blood lost by retention in the unit is kept very small.
