Abstract: The invention relates to a system and process for relining conveyor lines like pipelines (1) with an internal inliner (2) and an external inliner (preliner 7), whereby the internal inliner (2) forms a stiffened internal pipe (38) after insertion into the external inliner (preliner 7) and the external inliner (preliner 7) is arranged at such a distance from the internal inliner (2) that an open flow section is formed between the internal and external inliners as an inspection chamber to detect and, where necessary, remedy leaks in one of the inliners. Alternatively, the proposal is for a system and process with an internal inliner (2), a central inliner (3) and an external inliner (preliner 7) whereby the internal inliner (2) or the latter together wish the central inliner (3) form a stiffened internal pipe (38) after insertion in the external inliner and whereby the external inliner (preliner 7) is arranged at such a distance from the central inliner (3) that an open flow cross-section between the central and external inliners is formed as an inspection chamber (9) to detect and, where necessary, remedy leaks in one of the inliners.

Title: One-or two-leaf sliding door, swinging door or pocket door
Inventor: FINK MARTIN
IPC: E05F15/00
Filed: 1994-10-05
Granted: 2005-11-08
Abstract: The present invention relates to a one- or two-leaf sliding, swinging, or pocket door, with electrical, pneumatic, or hydraulic drive (10, 30), in particular for vehicles.        In order to avoid the danger of pinching or crushing that is brought about by structural elements in the area of the side closure region a spindle (12) is provided and this is connected to the leaf or leaves (1, 2) by way of a nut (21, 32) in which connection, in the case of two-leaved doors, the spindle is arranged so as to be symmetrical about the middle of the door and the door drive, producing either a rotary movement on the spindle (12) or a linear action on the door leaf (1). The spindle is fitted at one end with a free-wheel (23) and a releasable brake or coupling (24-28) that prevents rotation of the fixed part of the free-wheel, which means that a closing device in the area of the side closure region is eliminated.

Abstract: A plurality of drive motors are operated by fluid pressure for reciprocating the floor slats of a reciprocating floor conveyor.  A switching valve alternately connects the forward and  rear  ends  of  the  motors  to pressure  and  return  to reciprocate the slats.  A forward and a rear control valve each has a closed position in which it blocks direct communication between the switching valve and all but one of the forward and rear  ends,  respectively.    A  four-way  valve  has  ports communicating with pressure and return and with the pilot chambers of the control valves.  The four-way valve connects one pilot chamber to pressure and the other to return to cause the conveyor to convey a load in a first direction.  Reversal of the pressure and return to the pilot chambers causes a reversal of the conveying direction.  At least one forward end and one rear end of the motors has an internal control valve positioned to open and close a connecting passageway between adjacent motor ends.

Abstract: A vacuum apparatus for industrial hide driers with multiple beds (2) includes a circuit with an open end (17) having arranged in a series: a vapor manifold (7) for each bed; a first condenser (8) inserted in each manifold; a first condensate separator (10) at the output of the various condensers (8); a main vacuum pump (16) to gradually reduce the absolute pressure in the circuit to a first upper value (P s,). A particular feature of the system consists of the fact that it has a secondary aspiration device (19) which is arranged upstream of the main vacuum pump (16) to operate in series to this pump when the first value of the absolute pressure (P s,) is reached, so as to further reduce the pressure of the circuit to a second lower value (P i). The upper value (Ps) of the absolute pressure is 40 to 100 mbar; the second lower value (P i) of the absolute pressure is 15 to 1 mbar. The device (19) is a high-capacity, low-head blower.

Abstract: A system including a plurality of gas flow control units in cabinets which are connected to distribute process gas, on demand, to a plurality of utilization locations known as "tool" locations in a semi-conductor manufacturing plant. Transducers are used in the system to measure pressures and other control parameters. Zero calibration of the transducers is provided by automatically subjecting each transducer to a reference computer routine to compute the difference between the standard value and the transducer output, and store the difference as an "offset" to correct the output of the transducer. Thus, re-calibration is performed simply and quickly, at a relatively low labor cost and with relatively little downtime for the system.

Abstract: A light source destructuring and shaping device (6) which both homogenizes and imparts predetermined directionality to light rays emanating from a light source (7) is disclosed. The device comprises a micro-sculpted surface structure which controls the direction in which light propagates after reflection from, ortransmission through, the device. The sculpted surface structure also homogenizes light propagating through it with predetermined directionality. The device may be used in any application which requires homogenation of light and which would benefit from being able to impart directionality to light waves propagating from a light source. Applications include existing diffuser applications and applications where it is not practical to use conventional diffusers. The homogenizing and shaping device achieves these with high transmission or reflection efficiency and reduced side lobes.

Abstract: A method for shifting a powershift transmission of a vehicle in accordance with the load being experienced by the engine as estimated from certain engine operating parameters. A turbocarger associated with an engine operating at a given engine speed generates a turbo boost pressure. The turbo boost pressure is monitored by a sensor and a turbo boost signal is generated therefrom. Similarly, the engine speed is monitored by a sensor and an engine speed signal is generated therefrom. The turbo boost and engine speed signals are used to estimate the engine load based on empirical data stored in the transmission controller's memory, and a percentage load is computed therefrom. The percentage load is then used to generate an appropriate duty cycle and time value for a pulse-width-modulated shift signal which controls the modulation of an on-coming directional clutch into engagement at a desired rate of engagement dependent upon the load being experienced by the vehicle.

Dans l'encodeur, les données vidéo numériques présentent un débit d'encodage variable, par exemple un débit d'encodage intra-image et interimage, les points d'entrée (c'est-à-dire, les positions de début) des données vidéo encodées sélectionnées sont identifiés et qui représentent des images vidéo qui se produisent à des intervalles de temps prédéterminés (par exemple, 1, 2 et 4 secondes) dans l'image vidéo. Les données de point d'entrée qui identifient ces positions sont générées et ajoutées aux données vidéo codées avant que les données vidéo soient enregistrées sur un support d'enregistrement. Lorsque les données codées sont reproduites à partir du support d'enregistrement, les données de point d'entrée sont extraites à partir de ce dernier et stockées, et une image à codage intra-image suivante identifiée par les données de point d'entrée extraites est reproduite et décodée. L'invention prévoit en outre un support d'enregistrement sur lequel figurent les données vidéo numériques codées et fournit également un encodeur et le décodeur correspondant qui code et décode, respectivement, des images numériques fixes et des données audio dans lesquelles les points d'entrée se réfèrent à chacune des images fixes, ainsi qu'à des intervalles de temps particuliers des données audio.
