Title: Process and apparatus for producing a krypton/xenon concentrate by low-temperature fractionation of air
Inventor: ROTTMANN DIETRICH DIPL ING
IPC: F25J3/04
Filed: 1993-09-27
Abstract: To produce a krypton/xenon concentrate, a first fraction (14) is withdrawn from the lower region of the low-pressure column (3) of an air fractionation double column (1) and is fed to the lower region of a methane ejection column (5). In addition, a second, liquid fraction (15) from an intermediate point of the low-pressure column (3) is applied to the methane ejection column (5) from which a gaseous oxygen fraction (18) and a krypton/xenon concentrate (16) are taken off. In the process the mass transfer in the low-pressure column (3) is effected above the take-off point of the second fraction (15) at least in part by arranged packings and the mass transfer in the low-pressure column (3) between the take off points of the first (14) and the second (15) fraction is effected by rectifier plates. Alternatively or additionally thereto, the mass transfer in the methane ejection column (5) is effected at least in part by arranged packings. <IMAGE>

Title: Method of presenting optical information to rail passengers
Inventor: BREUNIG GEORG A VON
IPC: G09F19/22
Filed: 1994-02-02
Abstract: The method involves presenting optical information as a row of pictures (12) appropriately spaced along the route followed by passengers in a moving rail carriage (11). A stroboscopic lighting unit (13) illuminates the pictures with a time period t given by the equation t = d/v, where d is the spacing of the pictures and v is the velocity of the moving passengers. The stroboscopic lighting unit may take the form of a chain of lights driven by a control unit with a velocity sensor and a unit to detect presence of vehicle. If a row of identical pictures is used, the passengers will see a static image. Alternatively, a series of changing pictures may be used to create the illusion of a moving image.

Abstract: A safety edge assembly for a movable closure, such as a garage door, which automatically reverses the direction of movement of the door when the door comes into contact with an obstacle. The safety edge assembly comprises an electrically conductive mounting rail, which is fastened on the door, and a deformable tubular member which is supported by the mounting rail. A conductive member on the tubular member can, when the tubular member is deformed, be moved out of a first position, in which it is normally located at a distance from the conductive mounting rail, into a second position in which it is in contact with the conductive mounting rail, in order to close an electric circuit for controlling the direction of movement of the door. A closure plug for closing the open end of the tubular member has a non-conductive part for insertion between the end of the conductive member, which can fray upon cutting to the field length or can come out of its position in some other manner, and the end of the conductive mounting rail, in order to effect electrical insulation between the two. A method for controlling the actuation of a movable door, which method includes the step where an electrically conductive member on a deformable member on the guide edge of the door is moved towards the electric contact with an electrically conductive mounting rail on the guide edge of the door, ...

Title: Yarn transfer when rewinding yarn cake to yarn tube in pot spinning
Inventor: KOLTZE KARL
IPC: D01H9/04
Filed: 1994-07-29
Abstract: A yarn cake (12) is built up on the inside wall of a rotating spinning pot (11) by a traversing yarn guide (10) to be then rewound, pref. on a yarn tube (25). After the yarn cake (12) has reached a certain size and before the start of rewinding, the last traverse of the yarn guide (10) towards the centre of the yarn cake is shorter than the previous traverse. After the reversal point has been reached, the sliver supply (6) to the drafting system (3) is stopped and the yarn tube (25) is introduced into the spinning pot (11). The section of yarn between the tube and the yarn cake from the last traverse is wound on the tube and covered by subsequent yarn layers as rewinding progresses.  Pref. the last traverse pref. takes place in the upward direction and its length (h) is reduced. The entrained yarn end (2e) is overwound by subsequent layers during rewinding. The broken end of the yarn (2) remains inside the hollow traverse guide (10) and is cleared by short air jet blasts from the pneumatic injector (8) which normally acts as a threading up aid. The waste is blown into the inside of the yarn tube (25) and removed with the yarn tube during doffing.

Patent DE-4428494-A1 (DE)
Title: Recording head for an ink-jet printer and process for its production
Inventor: SUGATA YOSHINOBU
IPC: B29C65/02
Filed: 1994-08-11
Abstract: The resonance-chamber plate and oscillating plate of a recording head for ink-jet printing are formed from a polyether-imide resin. A polysulphone-resin layer of a thickness of 3  mu m is applied to one or both bonding surfaces of these plates. The melting temperature of the polysulphone resin is approximately 190 DEG C and the thermal deformation temperature of the polyether-imide resin is approximately 200 DEG C. If the resonance-chamber plate and the oscillating plate are in connection with each other via the polysulphone-resin layer and are heated to 190 DEG C for an hour, the polysulphone-resin layer is melted, producing a molten layer securely bonding the plates. Since the thermal-deformation temperature of the resonance-chamber plate is 200 DEG C, which is more than 10 DEG  higher than the melting temperature (190 DEG C) of the polysulphone-resin layers, no thermal deformation of the ink flow paths of the nozzles or the like occurs during the melting.
