For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

A cylindrical member (32) driven by a planetary gear arrangement (29) traverses an epitrochoid path to periodically enter a radial slot in an arm or disc (42) rotating the arm of disc through 180°. By selecting the parameters appropriately the cylindrical member is caused to enter and leave the radial slot along a tangential path such that no first or second derivative discontinuities are present in the motion of the arm or disc. Several embodiments are disclosed for achieving either one or two incremental rotations of an output shaft (40) for a single revolution of an input shaft (24).

A trapping technique which accepts a Postscript or other page description language (PDL) file and outputs a file in PDL format having the correct traps. The input page is first divided into sub-portions, or tiles, and the tiles are individually processed by evaluating the input file in a corresponding clipping window. Each tile is then analyzed to determine where edges exist. The edge data is fed to an edge converter which produces a list of color transitions consisting of the analytic description of each edge and the color information along the sides of the edge. The color transition information is fed to a trapping analyzer which generates trap vectors in accordance with a set of desired trapping rules. The trap vectors are then converted to PDL form. As a final step, the trap vectors are added to the original PDL file. The final trapped page may be printed on standard typesetters without the need for special trap generator hardware.

 Appl.No PCT/EP1992/000514 Applicant HENKEL KOMMANDITGESELLSCHAFT AUF AKTIEN Inventor MÜLHAUSEN, Georg
The invention relates to improving the handlability of a device for storing and dispensing liquid products, consisting of a reclosable tubular film sachet (1) with a pouring plug (3) containing the liquid product and a handling aid (14) to hold and handle the sachet (1) in the form of a can-like container open at the top with a moulded handle (17) and an aperture (18) in the upper edge of the container in the wall opposite the handle (17) and surrounded on three sides by the container wall. This improvement is obtained in that a fork-like, elastically openable tongue (21) with a recess (22) adapted to the aperture (18) is secured to the container wall with the formation of a gap (8) to take a preferably semicircular plug ring segment (7) on the pouring plug (3) in front of the region of the container wall surrounding the aperture (18).

 Appl.No PCT/EP1992/000443 Applicant STORA FELDMÜHLE AKTIENGESELLSCHAFT Inventor STEMMER, Manfred
The process makes it possible continuously to adjust the actual curvature to eliminate not-flatness in the manufacture of webs, especially in cardboard machines, by means of a pressure strip arranged in front of the take-up system having a guide component in the form of a round rod and rotated by means of a rotary drive. Here, the pressure strip (3) is fitted across the direction of travel (2) of the web and is movable perpendicularly thereto. The surface dampness of the upper and lower sides of the travelling web is continuously or intermittently measured and from the difference between the measurements xe1 thus obtained is derived the setting xa1, according to which the depth of penetration of the pressure strip (3) is adjusted.

 Appl.No PCT/GB1992/001398 Applicant LITETRONICS (U.K.) LIMITED Inventor MARNEY, Derek
A bracket (14) for a lighting assembly for use with a suspended ceiling arrangement comprises a hooked portion (2) to enable it to be located over and depend from a subgrid (16) of the ceiling arrangement and a plate (1) defining at least one open-ended slot (9). The slot (9) is substantially horizontal in use and a flange (15) of the lighting assembly can be fitted therein. A tag (10) is provided located adjacent the open end of the slot (9) and can be bent from a first position wherein it projects from the plane of the plate (1) into a second position coplanar with the plate (1) to cover the open end of the slot (9) and thereby retain the flange (15) in position in the slot (9). Preferably, the bracket (14) comprises two opposed slots (9) which are aligned on opposite sides of the plate (1). In this way a lighting assembly can be suspended from the bracket (14). The assembly preferably comprises at least one pair of opposed parallel support plates (13), each of which is provided with a flange (15) located respectively in one of the open-ended slots (9) defined by the bracket (14).

12Overvoltage protection resistors; Arresters
 Appl.No PCT/US1992/005807 Applicant JOSLYN CORPORATION Inventor OSTERHOUT, Joseph, C.
A high voltage surge arrester includes first (101A), second (101B) and third (101C) terminals. Arrester components, including one or more arrester valve blocks, are serially disposed in an insulating arrester housing between the first and second terminals. A first current carrying conductor is connected between the second and third terminals by way of a disconnector. If the arrester fails, the disconnector will disengage the first current carrying conductor (132) to provide a visible indication that the arrester has failed. At the same time, a second current carrying conductor (135) then reestablishes the connection between the second and third terminals. Thus, a current carrying conductive path is maintained between the first and third terminals.
