Title: Procede integre de liquefaction-gazeification du charbon
Inventor: CARR NORMAN L
IPC: C10G1/06
Filed: 1980-07-01
Abstract: Dans un procede de liquefaction du charbon le rendement en charbon liquide est augmente avec une diminution concomitante du rendement en charbon dissous solide, par le recyclage d'une boue de produit contenant des residus mineraux. Dans un procede integre de liquefaction-gazeification du charbon utilisant un recyclage d'une boue de produit (14) dans lequel le charbon dissous solide, de la zone de liquefaction (22, 26) comprend la totalite de l'alimentation en hydrocarbures vers la zone de gazeification (76), un rendement net modere de charbon dissous solide contribuerait a optimiser l'efficacite du procede integre. Toutefois, il est souvent difficile de mettre en oeuvre le procede a des taux de recyclage de boue qui soient suffisamment bas pour etre economiquement acceptables a cause d'une contrainte de pompage lie au niveau de solides dans le recipient de melange de l'alimentation en charbon. Dans le present procede l'operation mecanique est amelioree et une conversion accrue en charbon dissous solide est obtenue par le passage d'une partie de la boue de la zone de liquefaction a travers un hydroclone (60), le courant de trop plein (61) de l'hydroclone constituant une seconde boue de recyclage. Le deploiement de cette seconde boue de recyclage permet d'accomplir un recyclage selectif des petites particules de residus mineraux et tend a reduire le charbon dissous solide, sans necessiter de taux excessifs de recyclage pour contribuer a l'optimisation de l'efficacite du procede integre.

Abstract: In an envelope-shaped continuous porous support consisting of a heat-shrinkable, woven acid-proof material (polyester for example) closed on two or three sides, which can be used in lead plates of electrical accumulators, a small number of threads in the proximity of the sides consist of mixed yarns of a thermoplastic material (polypropylene for example) having a melting point lower than that of the acid-proof material and which is capable of melting and of agglomerating with them during the thermal shrinking treatment. This gives rise, along both sides, to the formation of a continuous, impermeable and electrically insulated strip, this increasing the lifetime of the accumulator plates. These envelopes can have, at regular intervals, intermediate ribs consisting of a yarn of much higher count and of a low melting point resin. During thermoforming, these ribs consolidate and finally give a semi-rigid cladding with incorporated ribs, which are mechanically bearing.

Abstract: The invention provides a method and apparatus for moulding articles. 
     The invention solves the problem of the moulding of cementitious materials in moulds in that it reduces the time taken to mould the article, increases the inherent strength, and additionally provides moulded articles that are much lighter than has heretofore been possible. 
     Essentially, the method involves forming the cementitious material in a mould (1, 2) and during or after the introduction of the cementitious material into the mould (1, 2) introducing an inflatable core member (6). When the mould is closed the inflatable core member (6) is used to pressurise the cementitious material thus expelling water and also forming a hollow core to lead to not only a stronger moulded article but also one that is considerably lighter than heretofore.

Abstract: The positive pole of dry cell battery B being recharged by the re-activator is connected to the positive D.C. output side of a full wave bridge rectifier 6 giving an un-smoothed cyclically varying D.C. output. The negative pole of the battery is connected by current path 14 to current path 16 to the collector of transistor 18 and by biasing resistance 22 and current path 20 to the transistor base connected to a high impedance winding 26 of transformer 28 having a low impedance winding 30 connected to the transistor emitter. The transistor turns on during each cycle of D.C. The current in winding 30 is a function of the battery impedance. Accordingly the voltage output of winding 26 is a function of the battery impedance and causes switch off of the transistor earlier in a D.C. cycle the lower the battery impedance is.

Abstract: A foldable, portable bicycle in which the handlebar, its elongated post, the seat assembly, the pedal crank and the frame are foldable quickly and easily into a compact and regular-shaped package that is easily portable and storable, and are unfoldable with similar speed and ease into a safe, durable and comfortable bicycle that accommodates adults of normal size. The frame is designed with a low profile that is substantially the same in height and thickness as the dimensions of the wheels and their supports, and the handlebar and seat assemblies extend upwardly to normal height, but fold and collapse in novel ways, along with the pedals, to substantially within the confines outlined by the folded frame. 
     Foldable pedal cranks are mounted on the crankshaft of the bicycle by male connectors on the opposite ends of the crankshaft in the form of lugs having opposite, parallel, generally radial sides on opposite sides of the crankshaft axis, and the inner end portions of the cranks are thickened and slotted on their laterally inner sides to form female connectors overlying the lugs. Pivots join the cranks to the lugs on the sides of the crankshaft axis opposite the outer end portions in the normal operating positions of the cranks, and snap-engaging latches releasably engage the lugs to hold the cranks in place. 
     For greater folded compactness, the cranks are inclined and offset laterally outwardly in the normal positions, to be reversed when folded, and to position the pedals for folding into the frame, each crank has a bend between its inner and outer end portions.

Title: Forward converter switching at zero current.
Inventor: VINCIARELLI PATRIZIO
IPC: H02M3/10
Filed: 1982-03-19
Abstract: A DC-to-DC converter processes power by a sequence of energy transfer cycles in each of which a quantum of energy is taken from a voltage source towards a current sink via a magnetic energy storage device (specifically a transformer having a small effective leakage inductance) and a capacitor. This (effective) LC circuit defines a characteristic time scale for the rise and fall of the current drawn from the voltage source so that a switching device connected in series with the source can be switched on and off at essentially zero current. Following each cycle the energy stored in the capacitor is released by the current sink. After the capacitor is discharged, the sink current is carried by a rectifier diode connected in parallel with the capacitor. This prevents the LC circuit from becoming a resonant circuit and leads to a unidirectional flow of energy from source to load which optimizes the efficiency and power density of the conversion process.

Title: Jeu logique a trois dimensions
Inventor: SZAKONYI VAJK
IPC: A63F9/00
Filed: 1982-06-22
Abstract: Le jeu comprend un corps associé à des éléments de jeu. Ce corps est suspendu à la Cardan par des organes d'appui et des organes de support, c'est-à-dire qu'il peut tourner librement autour de deux axes se coupant perpendiculairement dans le barycentre du corps. Les éléments de jeu sont munis d'organes pour leur fixation à n'importe quel point de la surface du corps où ces éléments peuvent constituer eux-mêmes ces organes de fixation. Le jeu est utilisé de la façon suivante: lorsque le corps a trouvé sa position d'équilibre dans la suspension à la Cardan, on perturbe cet équilibre par la fixation d'un élément de jeu sur sa surface, par exemple d'un élément magnétique appliqué sur le corps en fer doux. Le but du jeu consiste à rétablir l'équilibre initial et la position initiale en ajoutant des éléments supplémentaires en un minimum de temps. Lorsque le jeu comprend partiellement des matériaux magnétiques ou magnétisables il est nécessaire, pour atteindre le but du jeu, de ne tenir compte pas seulement de la force de gravitation mais aussi de l'attraction magnétique mutuelle des composants du jeu. Le jeu est donc amusant mais développe les facultés de la pensée logique et de la perception physique de l'espace, de la sensation empirique des corrélations mécaniques, et de la vision spatiale.
