Inventor: WALTER WOLFRAM
IPC: B29C63/00
Filed: 1997-10-16
Abstract: In  a  method  and  apparatus  for  automatically applying self-adhesive protective sheeting to surface parts of  vehicle  bodies,  a  specific  rectangular  piece  of protective sheeting in the form of stock roll is grasped on its non-adhesive side, using a robot-controlled tentering frame with suction legs,  is drawn off and is cut off.       Before the sheeting blank is laid on to the body, in the freely stretched-out state tear-off lines are perforated, preferably from the non-adhesive sheeting side,  in the region of accessory parts by means of a perforating device guided  along  definite  contour  lines.    Thereafter  the protective sheeting, which is thus prepared and stretched out so as to be free of creases in the tentering frame, is lowered in the correct position onto the associated part by the handling robot and laid onto the surface part so as to be free of bubbles.  The sheetings are subsequently pressed down in a brushing manner under an elastic brushing bar extending over the entire vehicle width. In the region of glued-over gaps in the vehicle body surface, the protective sheeting is severed and the cut edges are pressed down. In the region of accessory parts, protective sheeting parts are drawn off  along the perforated tearing  lines  and openings  are  thus  made  in  said  regions  in  a  manner appropriate for assembly.

IPC: A01B1/22
Filed: 1997-12-09
Abstract: An elongate tool handle, such as for a shovel, includes one or two spirit levelsembedded into the handle so as to assess alignment in perpendicular planes. The spirit levels incorporated into the tool allow the tool itself to be used to check vertical or horizontal alignment of posts, trees, and the like. The levels are selected, located and mounted on the handle in such a way that the levels are substantially received within the contour of the handle. The depth of the cavity in which the levels are imbedded is selected to avoid substantial impact on the strength of the handle. When two spirit levels are incorporated into the tool, they are arranged in a T configuration, one being oriented substantially transversely to the longitudinal axis of the handle, the other being substantially parallel thereto.

Title: Locking member device for tow pins on a vessel
Inventor: HYSTAD PER
IPC: B63B21/04
Filed: 1996-06-12
Abstract: A device involving locking members, so-called "flaps", for tow pins on a vessel, e.g., a tugboat, particularly for use with tow lines, towing wire, chains, or the like, where the tow pins are positioned in pairs at the stern of the vessel, optionally capable of being raised and lowered, for guiding the tow line or similar equipment therebetween, where each tow pin in a pair is provided to the top thereof with a respective projecting locking member, and where each tow pin is pivotable to permit the locking members to be brought by rotation into locking position by covering the opening between the upper ends of the pins, thereby limiting the vertical movement of the tow line or similar equipment positioned between the tow pins. Each locking member in vertical section and in a transverse direction outward from its respective tow pin has approximately a U-shape. The locking member seen in horizontal plane describes a curve in such a manner that said locking members when covering the opening between the tow pins together describe a curve extending in the direction of the vessel stern, and that the U-shaped cross section of the locking member at the part that faces toward the vessel stern has a gently curved form, while the part facing away from the vessel stern has a more upwardly oriented and less pronounced curved form.

Title: Pulsed fluidized bed
Inventor: GLASER RYSZARD
IPC: B01J8/40
Filed: 1998-04-28
Abstract: An apparatus and method for processing materials  in a batchwise or continuous fluidised bed, such as a drier, in which the fluidised bed is subdivided into a plurality of smaller areas, to each of which two separately controlled gas flows are provided.   The first lower gas flow is provided to the bed preferably all of the time,  and is  sufficient at  least  to maintain the bed in an expanded state.  The second higher gas flow is  provided to each separate area of the bed in sequence by means of a rotary valve arrangement, and is high enough to induce fluidisation  in  the  bed,  but  not  high  enough  to  induce significant solids loss by entrainment in the offtake gas.  The higher flow sequence can be chosen to provide almost any desired sequence to the separate parts of the bed.  The sequence can be chosen to induce a travelling wave within the bed which can be across or along the bed, and can be skewed relative to the sides of the bed.  In a continuously operated bed, the travelling wave can move either co-currently with,  counter-currently to,  or cross-currently to, the direction of flow of the solids through the bed.   This form of operation, particularly with a skewed travelling wave, improves bed operating efficiency.  Since the rotary valve cannot be closed completely, problems associated with abrasive dust in the gas feed, of valve lubrication, and valve  differential  thermal  expansion  are  all  substantially avoided.

Inventor: MCLEAN JOHN W
IPC: A61B6/00
Filed: 1995-11-14
Abstract: The system images the volume of a turbid medium and detects the contents. The medium can be water or air, or living tissue, or almost any other material which is at least partially light-transmissive. The system includes a light source for producing a series of discrete fan-shaped pulse beams that are substantially uniform in intensity or have been peaked at the edges of the fan to illuminate sections of the medium, a streak tube with a large, thin-slit-shaped photocathode for collecting the maximum amount of light from weak returns, a field-limiting slit disposed in front of the cathode for removing multiply scattered light, a large-aperture optical element for collecting and focusing the reflected portions of the pulse beam on the field-limiting slit and the cathode, and an array of detectors. A volume display of the medium is generated by translating the transmitter and receiver normal to the longitudinal axis of the pulse beam, to illuminate adjacent sections of the medium, and combining the sections to provide a volume display. All, or substantially all, of the light returned from each pulse beam is used. Vehicle motion can be used to provide the scan of the beam.  Applications range from foggy sky surveillance at multiple-kilometer scale to location of fractional-millimeter tumors in a human breast.

IPC: G08B15/02
Filed: 1997-01-30
Abstract: L'invention concerne une protection réactive contre le vol qui empêche, d'une manière active, que des biens ne soient volés. Le dispositif fonctionne comme suit: quand une intrusion est décelée, par exemple dans un magasin, en quelques secondes une fumée blanc-grisâtre se répand et remplit certaines parties ou la totalité de la pièce, en environ 10 secondes. Il n'est pas possible de supprimer la fumée et celle-ci peut continuer à se répandre pendant 10 minutes ou plus. Dans une forme d'exécution, on utilise des dispositifs émettant la fumée qui contiennent un gaz comprimé et un liquide fumigène, qui est normalement à la température ambiante. Le liquide fumigène est chauffé directement et rapidement, et transformé en vapeur par un chauffage électronique pour se répandre très abondamment et très largement par les buses.

Abstract: A raised pavement marker (10) includes a rigid reflector assembly (24) that supports two retroreflectors (26). The reflector assembly (24) is resiliently mounted over a base (14) by a resilient membrane (18), which is secured to the base (14) at the membrane's outer edge (20). When a vehicle contacts the reflector housing (25), downward forces supplied by the vehicle to the reflector housing (25) deform the membrane, which allows the reflector housing to move downwardly to pavement level. After the vehicle has passed, the resilience of the membrane (18) restores the reflector assembly (24) to its raised position. Methods for installing and removing the pavement marker (10) are disclosed.
