Abstract: Foodstuff packaged in a material transparent to microwaves is conveyed continuously through an environment pressurized to 2.5 bar max so as to prevent the containers or wrappers bursting or being forced out of shape; in four steps, the temperature is raised quickly to a prescribed treatment value with high frequency microwave radiation, stabilized by applying a combination of lower power microwaves and hot air, held steady with hot air only, and then lowered by cooling. In a split-level cylindrical oven, the upper level consists in a pressure-and-temperature compensating chamber (4), a high speed heat chamber (5) with closely spaced microwave generators (24) ordered in longitudinal rows along its top and sides, the waveguides (24′, 25) of which are directed at the containers or wrappers (C) of of foodstuff from above and beneath as they are indexed through on special pallets (S), and a stabilization cham­ber (5′) in which lower power microwaves combine with air drawn through heaters (20) and circulated by a fan (21) located at the closed end of the oven; the same air is used to heat a vertical chamber (6), through which the pallets descend on an elevator (D) before passing into a cooling chamber (7) on the lower level and proceeding toward the final outgoing compensating chamber (8). Once out of the oven, the pallets (S) are raised by a further elevator (A) to the upper level for emptying and reloading.

Abstract: Ce convertisseur est du type Cük, c'est-à-dire comportant : - côté primaire (10), un premier circuit série inductance-capacité-enroulement (11,12,13) et un organe actif de commutation (14), - côté secondaire (20), un second circuit série inductance-capacité-enroulement (21,22,23) et un organe passif de commutation (24), et - un circuit de commande (30) de l'organe actif de commutation, délivrant périodiquement à celui-ci des impulsions de commande avec une largeur variable en fonction d'un signal d'erreur, ce circuit de commande comprenant un générateur de rampes (120) et un comparateur (130) comparant le niveau instantané de la rampe (Vrampe) à un niveau de seuil (Vseuil) fonction du signal d'erreur. Selon l'invention, la pente de chaque rampe varie en fonction de la tension d'entrée et elle est indépendante de la tension de sortie, le niveau de seuil est fonction du signal d'erreur, et les impulsions de commande sont produites entre un instant fixe correspondant au début de chaque rampe et un instant variable correspondant au basculement du circuit comparateur. La variation de pente du générateur de rampe est commandée par une tension de commande (Vc) prélevée au point milieu d'un pont diviseur (111,112) monté en série avec une référence de tension (113), l'ensemble étant porté à une tension égale ou proportionnelle à la tension d'entrée (Ve) ; les valeurs de ces éléments (111,112,113) sont choisies de manière que la tension de sortie produite par le convertisseur sous le contrôle du circuit de commande soit rendue essentiellement indépendante de la tension d'entrée. Cette régulation en boucle ouverte assure une stabilité parfaite du système, avec un temps de réponse très inférieur à celui des convertisseurs Cük classiques.

Abstract: Un outil percutant pour instruments chirurgicaux comprend une poignée en forme de manchon, un porte-outil longitudinalement mobile dans la poignée et un piston oscillant longitudinalement entraîné dans la poignée et qui présente deux faces d'impact qui frappent des faces d'appui correspondantes du porte-outil et appliquent ainsi sur celui-ci des impulsions en sens opposés. Afin de pouvoir appliquer sélectivement des impulsions dans le sens de la percussion et dans le sens de rétraction, sans devoir modifier l'outil, la course réelle du piston dans la poignée est limitée de façon à être inférieure à la course de double impact que le piston devrait effectuer depuis l'impact de la première face d'impact sur la première face d'appui jusqu'à l'impact de la seconde face d'impact sur la seconde face d'appui si le porte-outil était fixe dans la poignée. Le porte-outil est mobile par rapport à la poignée et par rapport au piston dans la poignée.

Abstract: The invention relates to an antenna system having a main reflector 3 and an at least approximately hyperbolic auxiliary reflector 2 which is designed such that it rotates the polarisation plane of the electromagnetic waves emitted by a primary emitter 1 through 90 DEG . The metallic supporting body 21 of the auxiliary reflector 2 has a layer consisting of a low-loss dielectric 22 on which there is fitted a parallel line grid of conductive wires 23 at a grid spacing d which electrically corresponds approximately to one sixth of the operating wavelength. This results in a phase rotation of the waves through 90 DEG which is as exact as possible over the complete operating bandwidth. The main reflector 3 consists of a dielectrically absorbent supporting body 31 on which there are fitted a large number of conductive wires 32, arranged parallel to one another, whose grid spacing D is selected such that it corresponds approximately to one twelfth of the operating wavelength. The design according to the invention advantageously results in the reflection characteristic for the electromagnetic waves being largely independent of frequency for the operating bandwidth of the antenna system. <IMAGE>

Abstract: The process entails inside a liquid a reaction chamber (26) being separated by a semipermeable membrane (11) from a supply chamber (24). To date the exchange of material through the membrane (11) has been impaired by the fact that during the operating time a concentration gradient of the substances retained by the membrane has formed on the side of the reaction chamber in front of the membrane wall. This so-called secondary filter layer then reduces the rate of exchange of material. In order to prevent this, it is proposed that the direction of motion of the substances penetrating through the membrane (11) be temporarily reversed by pressure changes at time intervals. This measure results in detachment of the secondary filter layer without the particles forming it being exposed to damaging shear forces. Capillary membranes (11) whose interior (24) forms the supply chamber are preferably used. <IMAGE>

Abstract: The present invention is an improved lubrication system for a connecting rod [42], wrist pin [46], and piston [44] of a compressor. An oil pump [30] pumps lubricating oil upwardly within an axial bore [34] of the crankshaft [24], which includes a radial passageway [40] in alignment with the connecting rod. The connecting rod includes ports [64, 68] which direct pulses of oil onto the inner surfaces [72, 77] of the piston. The ports are separated by barrier segments [74] to allow local oil pressure to build between the alignments of the passageway and a port. Thus, pulses of oil are accurately sprayed onto the piston crown [60] without substantially diminishing the lubrication of the journal bearings.

Abstract: A breathing apparatus has first bellows (31) and second bellows (41), the first bellows (31) being so designed as to expand by a part of air exhaled by the diver or wearer of the breathing apparatus being supplied thereto through a mouth piece (4) and the second bellows (41) being so designed as to contract as the pressure of a surrounding atmosphere around the breathing apparatus, i. e., the atmospheric pressure under water. When the sum of an expanded amount of the first bellows (31) and a contracted amount of the second means (41) reaches a value which is equal to or larger than a predetermined value, an exhalation discharg valve (61) disposed on a mouth piece (4) is so opened as to discharge the exhaled air into a surrounding atmosphere around the breathing apparatus. This arrangement for the breathing apparatus enables the number of times of re-utilizing the exhaled air as air for inhalation to increase as the pressure of the surrounding atmosphere increases.
