Patent EP-0529573-A1 (EP)
Inventor: NOKIHARA KIYOSHI
IPC: C07K1/14
Filed: 1992-08-24
Abstract: The present invention is directed to a solid-phase synthesizer using a reaction vessel (1) which comprises a polyalkylene filter (2) or ceramic filter (2) packed in the bottom portion thereof. The reaction vessel used in the solid-phase synthesizer of the present invention can be used as a disposable reaction vessel. The reaction vessel in the present invention is free of resin adherence to the reaction vessel wall when the solid-phase resin (3) is packed in the reaction vessel, as seen in conventional glass reaction vessels, and it requires no pretreatment such as acid treatment because clogging does not occur because of the use of a polymeric resin instead of a glass filter.

Abstract: The tunnel finisher (20) has an L-shaped run-through tunnel (21) for drying laundry articles and making them crease-free. A steam zone (23) with steam nozzles (24) is essentially arranged in one leg (21') of the run-through tunnel, and a drying zone designated by (25) is located essentially in the other leg (21'') of the run-through tunnel. A laundry conveyor (26, 27) is subdivided into two part conveyors which are arranged at right angles to one another. The first part conveyor (26) is a rotating band conveyor or chain conveyor and a second part conveyor (27) is a worm conveyor. Arranged on the first part conveyor (26) are studs (30) extending transversely to the conveying direction (34) and on the second part conveyor (27) is arranged a helical bead (31) extending essentially over the entire length of the second part conveyor (27), in each case as a take-up member for the laundry articles (22) suspended on hangers. The large-area sides (32, 33) of the laundry articles stretched by the hangers are guided parallel to the conveying direction through the steam zone (23) and transversely to the conveying direction through the drying zone. As a result, along with compact dimensions of the tunnel finisher with correspondingly low heat-radiation losses, an unimpeded spraying with steam uniformly on all sides of the articles of clothing to be treated is obtained. A raised treatment quality is achieved with the tunnel finisher according to the invention. <IMAGE>

IPC: G01N1/00

Abstract: Particulate concentration of diesel exhaust is measured by collecting the diesel particulate on a filter while measuring the amount of exhaust passing through the filter. The filtered particlate is then heated in an oxygen rich enviroment to oxidize carbon within the particulate to carbon dioxide. The amount of resulting carbon dioxide is measured to derive a corresponding measurement of the amount of filterd particulate. Particulate concentration is calculated by comparing the amount of particulate with the measured amount of exhaust passed through the filter. Filtered particulate can be heated incrementally to obtain a measurement of volatile components within the particulate prior to the oxidation of the non-volatile carbon component. The filter employed to collect the particulate is of a high temperature resistant type making it reusable and can be either integral with or inserted into the oxidation chamber of the instrument. Oxidation of the particulate inherently concurrently cleans the filter for reuse. Particulate can also be collected for analysis by using an accelerating impaction nozzle in conjunction with a heatable impaction plate.

Abstract: Transporteuse à bande comprenant une bande transporteuse (10) suivant une partie de voie sans fin qui est formée par une voie de transport hélicoïdale constituée de plusieurs étages disposés les uns au-dessus des autres en une pile (12). Les bords de la bande (10) comportent des parties saillantes verticales qui servent à séparer les étages adjacents de la pile. La bande est entraînée le long de sa voie sans fin par un moyeu à entraînement rotatif (28) qui achemine la bande (10) à un endroit (22) où la bande (10) s'approche du sommet de la pile. Cet entraînement unique, à un endroit extérieur par rapport à la pile, évite la création de tension dans la bande et évite d'utiliser un quelconque dispositif destiné à éliminer la tension de la bande.

Abstract: Compositions polyester comprenant des unités monomères dérivées de l'acide 2,6-naphtalènedicarboxylique, de l'acide 4,4'-dibenzoïque et de l'éthylène glycol. Ces compositions sont employées comme fibres et résines de moulage lorsque le rapport entre l'acide 4,4'-dibenzyle et l'acide 2,6-naphtalènedicarboxylique est supérieur à 1:3. Ces compositions produisent une fibre aux caractéristiques de traction excellentes, aussi bien à température ambiante qu'à température élevée, lorsque les deux diacides sont présents dans un rapport molaire compris entre environ 60:40 et 40:60 et surtout lorsque les deux diacides sont inclus selon des quantités à peu près équimolaire. Lorsque ces compositions sont filées en fusion à une température de fusion relativement basse et dans un rapport d'étirage relativement élevé, les fibres obtenues présentent d'excellentes caractéristiques de résistance à la traction sans qu'une étape d'étirage ultérieure ne soit nécessaire.

Title: Continuously variable hydromechanical power transmission

IPC: F16H47/04
Filed: 1988-05-07
Abstract: The transmission consists of a five-shaft planetary gear mechanism, an infinitely variable hydrostatic transmission, geared rear-mounted shift stages and shift clutches. The hydrostatic transmission includes one positive-displacement machine (a) with a variable displacement volume and one (b) with a constant displacement volume. Of the planetary gear mechanism, one shaft forms the drive shaft (1) to which the variable-displacement machine (a) is connected. A second shaft (B) of the planetary gear mechanism is connected to the constant-displacement machine (b). A third shaft (C) serves as a starting shaft. A fourth and fifth shaft of the planetary gear mechanism (A, E) form coupling shafts. In an extreme position of the hydrostatic transmission, their speed is the same and, when the hydrostatic transmission is adjusted to the other extreme position, their speeds change such that one coupling shaft becomes steadily faster and the other steadily slower, these coupling shafts acting alternatively, in each case at least via two rear-mounted shift stages, also referred to as gears (speed ratios), on the output shaft (2). In the extreme positions of the hydrostatic transmission, shift clutches (Z) perform the gear change at synchronous speeds of rotation, in a load-free manner and without interruption to the tractive effort. The automatic transmission is controlled and regulated by electronic and hydraulic means.

Abstract: In a method for controlling a plastics injection-moulding machine, the operating parameters required for the sequence of an injection cycle are input in a form guiding the operator via an input unit (E) into a data processing unit storing these operating parameters, and subsequently injection cycles are carried out in accordance with the stored operating parameters. During the input, with knowledge of the possible process sequence of injection cycles governed by physical and machine-and mould-related design conditions, and after entering the devices existing on the respective machine or assigned to it, a selective choice of input possibilities is made available to the operator for the sequence and the configuration of the injection cycle. As a result, the parameters necessary for setting up the injection-moulding machine can be input faster, at the same time reducing the frequency of errors. <IMAGE>

Abstract: What is described is a spiked roller or spiked packer roller composed of individual roller rings (1) which have a track-ring cross-section taking the form of a penthouse roof and provided with teeth (5) distributed uniformly on the circumference. The valleys (6) present between the adjacent teeth (5) each have a rounded-out tooth bottom (6a). A higher load-bearing capacity of the new rollers can thereby be achieved. The differing flank angle results in a better self-cleaning capacity, a more extensive lateral reconsolidation effect, a greater cutting and splitting effect on hard soil clods and a higher breaking strength of the tooth rings. <IMAGE>
