Title: A magazine for flat cartons, prefolded leaflets and the like
Inventor: GREENWELL JOSEPH DANIEL
IPC: B31B50/76
Filed: 1983-06-22
Abstract: An orbital feeder for flat folded cartons (15), feeds the cartons from a stationary magazine (20) to a continuously moving conveyor (11). The magazine has a choke at its discharge end formed from parallel guides (141,142) which are spaced apart a distance less than the distance between the two folded edges of the cartons. A rotary carrier (25) is located adjacent the magazine and the conveyor. A plurality of planetary members (26), with attached suction cups (36) are rotatably mounted on the carrier. A fixed cam (30) cooperates with cam followers (2a) mounted on the planetary members to cause the planetary members to rotate on their own axes as the carrier rotates to pick up cartons from the magazine, open them and deposit them gently between transport lugs (12,13) on the conveyor. 
     The relatively simple feeder mechanism withdraws folded cartons from the magazine and deposits them erect on the conveyor quickly and efficiently.

Abstract: For the ultrasonic measurement of the wall thickness of synthetic hollow bodies, an ultrasonic transducer which is directly coupled in a dry manner to the surface of the synthetic hollow body (2) during the manufacturing process and measures its wall thickness is incorporated at one point or at a plurality of points in the mould (1) determining the external contour of the synthetic hollow body. The ultrasonic measurement is carried out from a point in time at which a temperature which is always repeated in the manufacturing cycle and at which the synthetic hollow body (2) is still plastically deformable has been established in its interior. The measured wall thickness values are compared with predetermined specified values by means of a set point/actual-value comparison and the deviation signals are used to readjust the parison die (3). <IMAGE>

Abstract: Gicleur de carburant pour moteurs à combustion interne, avec un pointeau de soupape (26) s'ouvrant vers l'extérieur, relié à un piston (46) qui borne une chambre de vaporisation (60) remplie de carburant et qui n'est relié lors de la première levée partielle du pointeau de soupape (26) au chemin d'écoulement du carburant que par une liaison étranglée. La chambre de vaporisation (60) est formée dans un chapeau (48) situé sur le piston (46) et centré sur celui-ci. La liaison étranglée se compose d'au moins un canal d'étranglement (66, 68, 69, 72) dont la section de passage, au contraire des modes de réalisation du brevet principal, est modifiée en fonction de la levée du pointeau de soupape (26). La section primitive de la liaison étranglée peut ainsi être limitée à une valeur très petite, sans que l'étranglement ait des effets négatifs lors de l'augmentation de la vitesse de rotation et des levées du pointeau. Dans certaines applications, la section d'étranglement primitive peut être avantageusement déterminée par un obturateur (62) réglé de manière fixe.

Abstract: With the process for the production of iron from an iron-oxygen combination, preferably ore, the iron-oxygen combination is essentially reduced in an ore reduction vessel with a reaction gas from a melting crucible, then supplied to this melting crucible and melted by adding carbon-containing fuels and oxygen-containing gases. According to the invention, the reaction gases escaping from the melted iron are partially subjected to after-burning in the melting crucible. The thus developing heat is largely transmitted to the melted material and the reaction gases are cooled and reduced with reducing agents on their way to the ore reduction vessel.

A primary coil (58) is supported coaxially about the secondary coil (62). Both the primary (58) and the secondary coil (62) coil include voltage divider segments having equal inductance with the primary coil segments (70,72) arranged in phase and the secondary coil segments (80,82) arranged 180° out of phase. The secondary coil (62) is completely insulated and isolated from ground. The primary coil (58) has a number of taps which are connected to the contacts (142) of a multi-position switch (76) so that the voltage in one of the segments of the primary coil may be varied so that the output of the transformer may be varied. This transformer provides a switchable primary circuit and a fully insulated secondary circuit.

Abstract: A film of uncured synthetic resin is used for the coating of metals, a piece of paper, a fabric or synthetic materials. The resin employed can be cured by exposure to ultraviolet radiation or to a beam of electrons; it is solid in the uncured state at temperatures below approximately 10-32 DEG C. The film is applied to a substrate which is or is not provided with a primer, and bonded to the substrate by heating and the application of pressure. The substrate coated with the film of resin is then exposed to a beam of electrons or to ultraviolet radiation in order to cure the film. When a supported film is used, the support film is placed on the upper face of the film of resin in order to protect it from exposure to air during the curing, and it is removed from the cured film in order to obtain the final desired product.

Abstract: Projectile de surface aquatique (10) pour la récréation et/ou l'exercice à utiliser soit individuellement, soit en equipe. On propulse ce dispositif aquatique à la main en le lançant de manière à lui faire effleurer la surface d'un corps d'eau par une action d'effleurement plan sans sauts ni culbutes. La surface inférieure (12a, 12b) du projectile a de préférence une forme tronconique inversée, les variables de la forme comportant le rayon intérieur (RI), le rayon extérieur (R0) et l'angle d'altitude (a). La forme de la surface inférieure produit une assiette à cabrer positive et une portance hydrodynamique afin de réduire la trainée en vue d'augmenter la portée et la vitesse du projectile tout en permettant un effleurement plan de la surface de l'eau. En plus des considérations relatives à la forme du projectile, ce dernier est aussi relativement léger afin d'accroître l'action d'effleurement et d'empêcher les culbutes et les sauts non désirés du projectile. L'angle d'altitude, le rapport de rayon (RI/RO) et le rapport surfacique poids par plan sont reliés entre eux conformément à des formules spécifiques.

Le déplacement de la plaque à échelles graduées (15) et des échelles (66...71) fixées à celle-ci prend en compte pour les couleurs de lecture des échelles le diamètre de l'élément à dresser conformément aux valeurs de diamètre de l'échelle (41) située du côté du cadre lors du réglage du dispositif de chargement et de charriage. Les coulisseaux (12, 13) permettent de tenir compte de l'inclinaison d'arrivée et de sortie de l'élément à dresser plié dans la machine de dressage et de la règler grâce aux échelles de mesure angulaire (72, 73). Transversalement au-dessus des échelles (66...73) sont tendus des indicateurs (16, 17) filiformes (42) que les crochets (84, 85) des coulisseaux (12, 13) amènent dans la position angulaire requise. Le dispositif (1) est le pendant déformé à l'échelle des mécanismes de réglage de l'installation de dressage. En utilisant des potentiomètres plutôt que des échelles (66...71), il est possible d'effectuer un réglage automatique des dispositifs de chargement et de charriage.
