Patent EP-0434601-A1 (EP)
Inventor: FLACHMUELLER WERNER
IPC: D02G1/02
Filed: 1990-10-24
Abstract: The invention is concerned with the production of non-twisted yarns from at least two fibril bundles. It provides intermediate process steps which are inserted between the main stages of the conventional production process for such yarns (spinning, drawing, texturing), in such a way that the mutual position of the individual fibril bundles, which is determined by the arrangement of the spinnerets, can be maintained throughout the entire process. A non-positively acting false-twist device for each individual fibril bundle, the intensity of which can be varied, makes it possible, furthermore, to vary in a reproducible manner the intermingling of the fibrils of the individual fibril bundles in their contact zones. <IMAGE>

Abstract: A chair control for a pedestal chair having a knee-tilt seat. An elastomeric torsion spring (41) is offset rearwardly from the tilting axis (73) of the seat. The seat and torsion spring are operatively connected by a cam surface (61) and a cam follower (81) which effectively reduce the restoring force exerted by the torsion spring against the seat as the rearward tilt of the seat increases. A mechanism (101) to adjust the initial restoring torque of the torsion spring provides a large angular twist of the torsion spring with a mini­mum linear movement of the mechanism. The chair control provides the chair seat with a less than conventional seat angle relative to the horizontal when the chair is unoccupied. A mechanism (121) is provided to enable the occupant to adjust the chair seat to a more con­ventional seat angle in its unoccupied condition.

Abstract: Un faisceau cohérent d'entrée émis par un laser (82) est introduit dans un mélangeur (8) à quatre ondes amélioré par une zone Brillouin qui génère un faisceau-semence à phases conjuguées qui se propage en sens contraire au faisceau d'entrée. Un amplificateur de Brillouin (86) agencé entre le laser et le mélangeur à quatre ondes transfère l'énergie du faisceau d'entrée (Ep) au faisceau semence (Ec), amplifiant le faisceau-semence de façon à produire un faisceau de sortie à phases conjuguées ayant approximativement 50 % de l'énergie du faisceau d'entrée et une bande passante étroite dépourvue des sauts aléatoires de phase associés au bruit acoustique généralement requis pour initier et maintenir une dispersion stimulée de Brillouin. Le faisceau de sortie à phases conjuguées peut être modulé ou dirigé selon les besoins. On peut dériver des faisceaux de référence pour le mélangeur à quatre ondes à partir de la même source laser que le faisceau d'entrée, avec des énergies inférieures d'un ou plusieurs ordres de magnitude à l'énergie du faisceau d'entrée.

This disc (2) can likewise consist, for example, of corrugated cardboard. The disc can thus lie between the end face of the roll and the tabs, but it can also be present in the sequence end face of roll, tabs, disc. <IMAGE>

Abstract: An electronic drum has two or more batons (102,104), each baton having a transmitter which transmits a distinct radio frequency signal at a position in space. The electronic drum determines the current X, Y, and Z coordinates of each baton transmitter (142,144). To determine the position of each baton transmitter (142,144), the drum includes a tablet (124) which has a flat support member at a predefined position, with at least two pairs of electrodes coupled to the flat support member. A first pair of the electrodes is shaped so that the amount of capacitive coupling between each baton transmitter (142,144) and one of the first pair of electrodes corresponds to the position of the baton transmitter (142,144) with respect to the X axis. A second pair of electrodes is shaped so that the amount of capacitive coupling between each baton transmitter (142,144) and one of the second pair of electrodes corresponds to the position of the baton transmitter (142,144) with respect to the Y axis. The electrodes pairs are shaped and positioned so that neither electrode pair shields the other, which allows for accurate X and Y position measurements. The drum also has a CPU which receives signals from the electrodes, and uses those signals to compute the X, Y and Z coordinates of each baton (102,104). The CPU also predicts when each baton transmitter (142,144) will hit the drum's flat support member and generates a signal at the predicted time so that a music synthesizer can generate a sound at the appropriate time.

Abstract: A launder system (16) for supplying molten metal (14) from a crucible (10) to a casting mould or a secondary process comprises a nozzle (22) which has a filter (26) positioned within the nozzle (22) to filter the molten metal as it flows through the nozzle (22). 
     The nozzle (22) and filter (26) assembly is removably locatable on the launder system (16), and is used once and is replaced by a new nozzle and filter assembly. 
     This allows efficient cleaning of the molten metal without an increase of probability of blockage due to the filter. The scrapping rate of the launder system is reduced, and hence the launder may be used many times.

Abstract: A suction transfer assembly (1) for a medicament liquid (L), especially a hazardous liquid, that permits safe and easy transfer of liquid (L) from its container to a suction operating dispenser device such as a syringe (60), yet avoids leakage on detaching the device from the assembly, comprises a longitudinal vial (10) and longitudinal adapter (30). The vial (10) forms an enclosed longitudinal chamber (14) filled with the medicament liquid (L) and has an open end (13) closed by a penetrable stopper (15). The vial (10) is slidable longitudinally relative to the stopper (15) and the stopper (15) seals the liquid (L) in the chamber (14). The stopper (15) has fastening means (19) facing the vial open end (13). 
     The adapter (30) has front (31) and rear (32) ends and an internal flow path (33) extending therethrough. The rear end (32) has a rearwardly facing hollow needle (36) with a pointed tip (37) defining the flow path (33) rear terminus, and fastening means (38). The rear end (32) is insertable into the vial open end (13) to fasten the adapter fastening means (38) to those of the stopper (15) and to penetrate the stopper (15) by the needle (36) so as to connect the chamber (14) and flow path (33). 
     The adapter front end (31) has a forwardly facing hollow nozzle (39) defining the flow path (33) front terminus, a self-closing check valve (40) in the flow path (33) adjacent the nozzle (39), and a lock connector (45). A suction device (60) can be locked to the adapter (30) so as to open the check valve (40). Suction operation of the device (60) will cause liquid transfer from the chamber (14) via the adapter (30) to the device (60) and simultaneous compensating vial (10) movement longitudinally relative to the stopper (15) under external atmospheric pressure to reduce the chamber (14) volume by an amount generally equal to the liquid transferred.

Abstract: Multiple "green" ceramic sheets are formed from a particulate ceramic material and a volatilisable organic binder, have individually printed thereupon a pattern containing conductor metal/metal oxide material from a suitable printing composition, and are thereafter assembled in registry with each other and laminated. Each such article is subjected to a heat treatment comprising a first heating stage under conditions to promote burn-out of the organic polymeric binder present, a second stage performed under conditions to reduce the metal oxide to metal, and a third stage to sinter the ceramic to form the final ceramic article. Moisture (water vapour) is present in an amount of from about 0.5% to about 3% volume of the gaseous atmosphere in at least the sintering stage, and preferably in both the binder burn-out stage and the reduction stage as well. Multilayered articles heat treated under these conditions exhibit a combination of improved properties, including little or no staining in combination with improved conductivity and dielectric properties. In a preferred embodiment, the present method may be performed as a continuous process without the need for cool-down and heat-up of the laminate, in a continuous furnace with an atmosphere that is microprocessor-controlled. Catalytic generation of the moisture containing heating atmosphere may be utilised to further reduce cost and processing time while increasing process efficiency and productivity.
