Abstract: A container, such as a soda siphon, comprises a vessel (2) of blow-moulded plastics material, such as PET. A valve assembly (20), similar to those commonly used with aerosol containers, is received in a neck (6) of the vessel (2). A dispensing head (8) is fitted to the neck (6) over the valve assembly (20). The head (8) has an actuator element (30) which fits over an outlet tube (24) of the valve assembly (20). The actuator element (30) is hinged (at 34) to the rest of the dispensing head (8) and has a passageway (32) which communicates with an outlet nozzle (12). Depression of the actuator element (30) causes the valve to open, and the carbonated liquid flows through the outlet tube (24), the passageway (32) and the outlet nozzle (12). The construction of the container means that its components can be made economically, so that at least the vessel (2) and the valve assembly (28) (and possibly also the dispensing head (8)) may be disposable when the contents have been used.

Title: Esterification process
Inventor: VAN DEN BERG HENDRIKUS J
IPC: C07C67/08
Filed: 1990-12-19
Abstract: The invention provides a process for the esterification of a C₂-C₂₄ monocarboxylic acid with a C₁-C₅ monoalcohol in a reactor at an increased reaction temperature and increased pressure which is carried out in the absence of any esterification catalyst whilst continuously feeding in the alcohol during the reaction and removing a gaseous alcohol/water mixture. Preferably the process is carried out in countercurrent in column reactor which is packed or contains plates. The reaction temperature is usually between 200 and 260°C at a pressure between 0.5 and 1.5 MPa. There is a C₆-C₂₀ monocarboxylic acid and monoalcohol a C₁-C₃ monoalcohol. More preferably the process is carried in two steps with a first step as described above and a second step in which further reaction to a conversion of at least 99% is carried out in the presence of an esterification catalyst at a temperature below 100°C.

Abstract: A DC motor is provided with a brush arrangement in which two parts of the brushes are arranged around the peripheral surface of a commutator so that each line across the opposite brushes with respect to the central axis of the commutator forms an angle, thus the space between the positive and negative brushes is sufficient to mount components thereon. Each width of the brushes is determined by the number of conducting segments in contact with the brushes of the same polarity, affording sufficient current to flow in the brushes.

Abstract: Il est proposé un système de régulation combinée pour véhicules automobiles qui est composé d'une régulation active et/ou semi-active du châssis ainsi que de composants du système antiblocage et/ou antipatinage à l'entraînement, lesquels disposent de capteurs et de circuits communs d'évaluation ou de commande. Il est prévu que les circuits d'évaluation déterminent un niveau de sécurité et que les circuits de commande transmettent, en fonction de l'évaluation de ce niveau de sécurité, des signaux de commande aux composants du système antiblocage/antipatinage à l'entraînement ainsi qu'à la régulation du châssis. Ces mesures permettent une utilisation maximale des capteurs et unités de commande existants ainsi qu'une prise en compte particulièrement facile des interactions entre variations de la chaussée et manoeeuvres de conduite. On obtient ainsi un réglage toujours confortable mais néanmoins répondant à toutes les exigences en matière de sécurité, ainsi que des avantages en matière de sécurité et de vitesse pour le système antiblocage/antipatinage à l'entraînement.

Title: Process for adjusting the tension in a tape.
Inventor: SCHANDL HARTMUT
IPC: G11B15/665
Filed: 1990-11-22
Abstract: A system for adjusting the tension of a tape in a magnetic tape record/playback device includes a feed spool, a take-up spool and a motor for feeding the tape between the spools in a forward direction and a reverse direction. A tension sensor senses the tension in the tape as the tape is fed in the forward direction. The tension sensor is locked in its last existing position when the tape direction is changed from the forward direction to the reverse direction. A slip coupling applies a pre-adjusted tension to the tape when the tape is fed in the reverse direction.

Abstract: The fluid actuator has a longitudinally slotted cylinder (1) in which a piston (3) having a connection means (12) reaching through the slot (10) in the cylinder (1) is axially displaceable. The connection means (12) is firmly connected to a driving feature (13) which can be moved in front of the slot (10) on the outside of the cylinder. The driving feature (13) is overlapped by a power output member (14) which is guided in longitudinally displaceable fashion directly or indirectly on the cylinder (1) separately from the piston (3). To couple the driving feature (13) to the power output member (14), the driving feature (13) has a transverse groove (20) on the side facing away from the slot, in which groove there is a feather key (22) crossing the slot (10) at right angles. The feather key (22) extends beyond the transverse groove (20) on both sides and engages with its end portions in corresponding recesses (21) of the power output member (14). The coupling device between the driving feature (13) and the power output member (14), consisting of the feather key (22), the transverse groove (20) and the recesses (21) can be designed to be parallel to the cylinder axis (9) and virtually without play in the pourer transmission direction but allows sufficient relative movements and rotations between the driving feature (13) and the power output member (14) for practical use, such that jamming is reliably avoided. <IMAGE>

Abstract: During the instruction processing in accordance with the pipeline method, in each case one branch prediction (for example PB1) is allocated to all possible combinations of n past branch decisions to be taken into consideration (for example HB0,HB1,HB2) for each branch instruction, and stored together with the current history of the respective branch instruction. This allocation can be dynamically varied in that the branch prediction (for example PB2) allocated to the current history (H0) is selected from the 2<n> branch predictions (for example PB0...PB7) in each case stored for the branch instruction to be executed, and in the event of a wrong prediction result, the current branch decision is directly stored as modified branch prediction (PN) together with the changed history (HN). <IMAGE>
