Abstract: The storage and retrieval apparatus uses pallets (20) for storing vehicles and other loads. A number of storage levels aligned vertically are reached by a pair of lifts (L1, L2) in shafts (50) which bracket the levels. A transfer mechanism can push a pallet (20) and automobile from either lift (L1, L2) onto any level. Each level is always filled with pallets (20) and sized to exactly hold an integral number of pallets (20). When a pallet (20) is pushed into a level from one lift the intermediate pallets are pushed laterally to the opposite lift, resulting in the farthest pallet being ejected onto the opposite lift located at the same level. Separate loading stations (S1, S2) are provided on ground level for each lift (L1, L2). An automobile can be driven on or off a pallet (20) or a load placed on or off a pallet at the loading station. A loading station mechanism can move a pallet (20) with a load to be stored from the loading station onto a lift. The lift transfer mechanism can transfer a pallet (20) with a load being retrieved from the lift onto the loading station mechanism adjacent the lift, and the loading station mechanism can move the pallet from there to the loading station. A computer having input apparatus, input sensors, output apparatus and displays, utilizes a program to control and optimize the operation. Input identifies for each automobile, or other load, and pallet are entered into the computer upon storage to permit ready retrieval.

Abstract: The invention relates to air cooling of control cabinets (1) which are equipped with circuit boards and have a housing (2), at least one fan (12) sucking in cooling air and an area of parallel circuit boards (3) which are provided with electrical components that generate heat. The cooling air flow is ducted from the fan inlet (18) to the inlet (20) between the circuit boards, and further along the circuit boards to the outlet (21). Each inlet (20) to a duct running along the circuit boards consists of a baffle plate (10) having very small openings (13), the cross-section of which baffle plate (10) can be set to a multiple of the cross-section of the very small openings. As a result of the restriction effect of the very small openings (13) a pressure builds up in front of them which on the one hand causes a more even flow distribution over the very small openings (13) and, on the other hand, makes it possible to increase in a selective manner the air flow rate for circuit boards (3) which are thermally severely loaded, using enlarged opening cross-sections on the baffle plates (10). …<IMAGE>…

Title: Erbium-doped fibre amplifier with shaped spectral gain.
Inventor: PAYNE DAVID NEIL
IPC: H01S3/067
Filed: 1991-05-21
Abstract: An optical amplifier comprises a waveguide with one or more rejection band filters (eg gratings) 12 between the ends of the waveguide, the rejection band being matched to the peak wavelength of the gain spectrum whereby the gain response is flattened. ASE power is suppressed, for example. An interference filter (36) may be used (Fig. 6), and the waveguides may be planar with a meandering section or a periodic perturbation as filter (Fig. 7). Thin filter chips, coloured-glass, Fabry-Perot, and Bragg filters are also specified. The filter may be continuous along the waveguide and may be a dopant. The filter may narrow the spectral gain. Er or Nd-doped rare earth and s/c amplifiers are exemplified. Telecommunications and wavelength-division multiplexing applications are detailed. <IMAGE>

Title: Hydraulic or pneumatic auxiliary drive for manual sheet-metal forming tools.
Inventor: LIPP ALEX
IPC: B25B5/06
Filed: 1991-07-05
Abstract: More or less compressed air is admitted into the diaphragm cylinder (5) by allowing compressed air to enter via the treadle valve (3). The pressure plate (7) is moved horizontally forwards over the thrust rod (6) via the guide in the securing plate (9) by the entry of compressed air into the diaphragm cylinder. The travel of the pressure plate (7) is determined by the two spacers (13). The upper and lower levers (8) each slide along the outward-moving surfaces (17) of the pressure plate (7) via a roller (16) and actuate the tool insert (11) via a pivot (10). Pressure is generated between the conversion set and the manual forming tool and is transmitted to the two securing brackets (14). If the treadle valve (3) is closed, the compressed air flows from the diaphragm cylinder (5) through the quick-release valve (12). Owing to the pressure drop in the cylinder, the pressure plate (7) is drawn back over the thrust rod (6) into the starting position by means of a return spring.

IPC: B65D30/24
Filed: 1991-10-01
Abstract: The invention relates to a sack (1) or a similar flexible package and a packing method based on the use of such a sack. The sack (1), which is intended for packing fine-ground material, is provided with a filling duct (3) leading inside the sack and made of flexible material and a bendable covering patch (12) protruding from the sack with the aid of which the end (11) of the filling duct can be closed after the filling of the sack. It is essential to the invention that the filing duct (3) extends at least to the bending line (13) of the covering patch (12) and preferably past it and that the filling duct (3) is, at least at the end thereof, narrower than the covering patch (12). Thus the covering patch (12) can be bent against the surface of the sack and attached thereto in such a way that it forms a uniform closing zone closing the end (11) of the filling duct in a cross-direction and extending to each side thereof.

Abstract: Un mécanisme de mémorisation et d'acquisition d'imagerie numérique commande le fonctionnement d'un analyseur de film numérique à haute résolution (12) de sorte que l'analyseur analyse deux fois l'image, la première exploration servant à rassembler des données pour étalonner l'analyseur (12) et la deuxième exploration servant à acquérir et à mémoriser une image à haute résolution. L'analyseur exécute un mode à faible résolution, la pré-exploration de l'image photographie en couleurs, et on obtient ainsi une image numérique à faible résolution spatiale. Cette image numérique à faible résolution est ensuite analysée par un mécanisme de balance des couleurs d'une scène (14) qui permet de déterminer de quelle manière la caractéristique de réponse du réseau de pixels d'imagerie de l'analyseur voit l'image et code son contenu spatial. Le résultat de cette analyse, qui représente le contenu de la balance chromatique de l'image numérisée, est utilisé pour régler la plage de sensibilité de l'analyseur de sorte qu'au cours d'une autre exploration à haute résolution de l'image, le sujet principal de limage se situe dans la partie linéaire de la plage de réponse du réseau de pixels d'imagerie de l'analyseur. L'image numérisée à haute résolution est ensuite traitée par le mécanisme de balance des couleurs d'une scène (14) pour mapper les données d'images en une image numérisée ayant une résolution de codage réduite correspondant à celle d'une mémoire d'images attenante.

Abstract: Improved oral dosage formulations for acid-labile dideoxy purine nucleoside derivatives such as ddA, ddI, and ddG, have been developed by incorporating selected water-insoluble buffering systems in the formulation. These novel formulations provide reduced mass dosage units in the form of convenient, palatable chewable/ dispersible tablets or a dry powder sachet. The reduced mass requirement, necessary to allow tablets of reasonable size, was achieved in part by an unexpected 20 to 25% increase in drug bioavailability resulting from use of the selected buffering systems comprised of an insoluble magnesium antacid agent and either dihydroxyaluminum sodium carbonate or calcium carbonate.
