Patent EP-0324904-A1 (EP)
Inventor: WEISS HANS DIPL-ING
IPC: H02M7/217
Filed: 1988-10-26
Abstract: A power supply is proposed for producing a regulated DC voltage from a mains AC voltage, which power supply has a capacitor (18), which exhibits the output DC voltage (Ua) and can be charged via a rectifier arrangement (11), and a semiconductor switch, which bridges the output of the rectifier arrangement (11) and can be controlled as a function of a predeterminable nominal value (U2) and the actual value of the output voltage (Ua). A control device (16, 17, 19), which moves the semiconductor switch into the conducting state in synchronism with the mains AC voltage or with the rectified voltage half-cycles derived therefrom and moves the semiconductor switch into the blocking state if the actual value is less than the predeterminable nominal value (U2), is connected upstream of the semiconductor switch, at least one resistor (8, 9), preventing a current overload of the rectifier arrangement (11), being provided between the mains connection and the semiconductor switch. Since only a very low voltage is in each case applied to the semiconductor switch (13) at the times when it switches, the power loss and the radio interference are kept small. <IMAGE>

Abstract: The invention relates to a method and apparatus for removing conical yarn bobbins (8), particularly in relation to withdrawing them from a conveyor belt (12) which receives and moves said conical bobbins after they have been doffed and discharged from the units of a bobbin producing textile machine (25), and depositing them in an ordered arrangement on a peg trolley (22). 
     The apparatus comprises essentially: 
- a shelf-like collection station on which there is fixed at least one sufficiently inclined cradle-shaped roller track (2a) for laterally guiding the full bobbins (8) leaving the conveyor belt (12); 
- a portal manipulator unit with a pendant arm (3) provided with a pin-type gripper (5) which penetrates and withdraws several bobbins one behind the other to transfer them from their prepared-for-withdrawal position to their ordered deposition position by means of vertical and horizontal translational movements and rotational movements generated and coordinated by drive sources (7,9) which are activated and controlled, moment by moment, by a control unit (20); 
- a control unit (20) based on a miniprocessor into which an operating program and a set of operating data for   computerised positioning are fed. Said control unit also comprises a computing centre which determines and memorises the number of bobbins to be deposited in an ordered arrangement on the pegs of the creel trolley (22), progressively compares the deposited number of bobbins with the memorised number, and generates a luminous and/or acoustic end-of-cycle signal when the number of bobbins deposited equals the number memorised.

Abstract: A video imaging system is disclosed. The system is responsive to electrical signals introduced into it, which electrical signals represent an image. The system includes an acoustic-optical cell (31), the cell including an anisotropic medium for sound transmittal. The electrical signals are received, and optionally compressed (53), before being introduced into transducers (42) mounted on the cell. The trans­ducers convert the electrical signals into sound waves which traverse the width of the cell. After substantially a full line of display of the image is travelling through the cell, a monochromatic light source (11), such as a metal vapor pulsed laser, is pulsed for a time duration less than the propagation time of a single pixel across or transverse to the sound signal in the cell. This modulates the mono­chromatic light which is then focused (63, 71) and displayed on a screen (81) at the appropriate position for the line of image.

In one embodiment etherification is conducted in the presence of a large excess of methanol wherein unreacted methanol is separated in a fractionator utilizing a light hydrocarbon stripping gas to separate the methanol-hydrocarbon azeotrope. In another embodiment unreacted methanol from the etherification reaction is removed by water washing. The aqueous mixture containing unreacted methanol is separated in a stripping zone employing fuel gas as a stripping media.

Abstract: The stopping means comprises an intermediate chamber (15) arranged at the free end of the neck (2) of a flask (1). This chamber is delimited at its upper part by an elastic membrane (14) mounted rotatably relative to the axis of the neck. At its lower part, it is limited by a fixed base (10) perforated with two inlet orifices (16) to the chamber. An outlet orifice (18) from the chamber (15) is arranged in the centre of the membrane (14) and a projection (17), located opposite the outlet orifice (18) on the base (10), closes the latter. The membrane (14) comprises protuberances (19) which penetrate partially into the inlet orifices (16) and close them off, producing locking of the device. Rotation of the membrane (14) by acting manually on the skirt (12) of the movable cap (6) gives rise to an elastic deformation of the membrane and releases the device, placing the inside of the flask and the chamber (15) in communication via the inlet orifices (16). By increasing the pressure beyond a specific value inside the flask, the membrane (14) is further deformed and the outlet orifice (18) is disengaged from the projection (17), the device then being in the open position. <IMAGE>

Title: Apparatus for thermal aftertreatment of carbon fibres from coaltar pitch, in particular from glance- (hard)- coaltar pitch.
Inventor: GEIER RUDOLF
IPC: C10C1/00
Filed: 1988-01-05
Abstract: In a process for producing carbon fibres from coal tar pitch, the coal tar pitch is filtered before being spun and the pitch filtrate is distilled in a thin-film evaporator in order to increase its softening point over 260 C. A pure and homogeneous hard pitch is thus obtained, without the re-formation of infusable, chinolin-insoluble components. The most difficult and cost intensive step of the fibre production process, namely the thermal aftertreatment of the spun pitch fibres, can thus be easily and quickly carried out. The subsequent thermal treatment is carried out in a cyclic treatment installation.

Abstract: Dans une tenture relevable (10) pour fenêtre, telle qu'un store pliant ou un voilage, on utilise une bande de tissu (11) qui présente sur sa face envers plusieurs ensembles parallèles et verticaux (16, 17) de boucles pourvues d'éléments de guidage, qui sont formées sur une bande pliante fixée sur la face envers de la bande de tissu (11). La tirette (21) est fixée dans la région marginale inférieure de la bande de tissu (11) et s'étend jusqu'à un support horizontal (29) fixé sur la région marginale supérieure de la bande de tissu (11). Dans le but de garantir un aspect impeccable de la tenture (10) et de pouvoir adapter aisément celle-ci à des hauteurs de fenêtre variables, l'invention propose que les boucles s'étendent horizontalement dans les ensembles et soient formées chacune à partir d'une nappe de fils de trame (24) flottant sur la bande de tissu (11) ou la bande pliante. Un lien est simultanément passé à travers au moins deux nappes de fils de trame (24) espacées verticalement, qu'il rapproche, tandis que la région de la bande de tissu située entre les deux est drapée pour former un pli horizontal permanent (44).
