Abstract: A scoop strainer has a rim to attach the strainer to an outer surface of a hull of a marine vessel over a through-hull fitting intended to admit water to the interior of the hull. The strainer has small openings therethrough to pass water but not large undesired objects or marine life, and a larger opening to permit access to the interior of the strainer and to the through-hull fitting to clean out marine growth and the like. A cover is hinged to the strainer and is movable between an open, access position and a closed position. A threaded fastener passing through the cover threads into the rim to selectively hold the access cover closed.

Abstract: An endoscopic telescope has a system tube in which spacer tubes are alternatingly stacked with rod lenses each having an external diameter smaller than the inside diameter of the system tube and which have convex end faces supported against the axial ends of the spacer tubes. An end of at least one of the spacer tubes protrudes axially at an angle and at a rotational position so that it abuts the adjacent convex surface of a rod lens, thereby tilting the rod lens relative to the system tube axis. The spacer tubes and the rod lenses are mounted spring loaded between end holding devices in the system tube.

Abstract: The invention concerns a movable object, e.g. a roll of printed products (1) with a winding core (2) onto which printed products are wound with the help of a winding tape (3). The inventive movable object carries data stored in an integrated circuit (23) and an antenna, whereby the data can be read or overwritten respectively without contact by a reading/writing device with a main reading direction (L). The antenna is designed as an antenna loop (5) with a gap, whereby the ends of the loop (5) are contacted with the integrated circuit which is e.g. arranged on a connecting piece and whereby an antenna area is defined by the antenna loop (5). The object is positionable relative to the reading/writing device (10) such that the main reading direction (L) penetrates the antenna area vertically or obliquely.

Abstract: A superstructure (1) for an endosteal dental implant (2) has a longitudinal axis (11) and an outer surface (12), which has buccal, lingual, mesial and distal regions, and an annular surface (8) which is intended for the connection to a dental implant (2) and is orthogonal to the longitudinal axis (11). The superstructure (1) is further provided with a connection for accommodating an orthodontic element (6).

Abstract: A pulsed solid-state laser comprises an optical resonator and a solid-state laser medium placed inside the optical resonator. A saturable absorber, such as a semiconductor saturable absorber mirror device for passive mode locking is placed inside the optical resonator, and a pumping source is provided for exciting the laser gain medium to emit electromagnetic radiation. The pumping source emits pump radiation which impinges on the laser gain medium in the form of a non-diffraction-limited focused pumping beam. The product of the stimulated emission cross section times the spontaneous fluorescence lifetime is low for the laser medium, e.g., 0.1.multidot.10.sup.-23 cm.sup.2 s for Ti:sapphire; nevertheless, the laser yields a high output power of a few Watt even if pumped with a non-diffraction-limited pumping beam. Pumping with a non-diffraction-limited pumping beam makes feasible solid-state lasers with remarkably smaller sizes and lower costs, but with the same performance as known lasers.

Abstract: A flat embossing machine for flat material (5) to be embossed has a flat press (2), an embossing table (3) and a tool plate (4). At least one foil web (6) passes through foil loop stores (10, 20) each with a differential pressure device (30) for shaping a foil loop (12) with an air pressure difference exerted on the foil web. A foil feed device (24) and a tensioning device (25) are on each side of the flat press and a foil feed control (52) operates in synchronism with the press cycle so that the foil web is stopped during the embossing phase (TP) on the embossing table (3) and is advanced to the next embossing position during the embossing-free phase. Speed differences between the feed speed (VV) at the embossing location and web speed (V7) at the unwinding roll or at the removal device (V8) are compensated for by corresponding increases and decreases in the size of the loops (L1, L2) in the foil stores. This allows high embossing speeds with optimum quality.

Abstract: A laboratory centrifuge has a centrifuge rotor supported on a stator and rotatable on a bearing about an axis of rotation. An electric motor drives the rotor and has pole pieces at a stationary part mounted on the stator and a rotatable part directly attached to the rotor, the stationary part having pole pieces with drive coils. The pole pieces magnetically act through a gap between the pole pieces and the rotatable part, and the gap lies in a surface which is perpendicular to the axis of rotation or forms a shallow frustocone opening either upwardly or downwardly.

Abstract: Magnifying spectacles for surgical use have an automatic focusing device, a device for automatically altering the magnification factor and a device for automatic parallax compensation corresponding to the current focal length. During surgical operations, alteration of the working distance is commonly necessary due to the positions of different operating sites. Automatic adaptation of the focal length and the parallax angle allows optimum optical configuration to be reached without the need for the surgeon to use his hands. Focusing can be adjusted using a foot switch.

Abstract: A surveillance camera assembly has an apparatus (9-15) for providing a rotatable field of view in a plane with a tilted mirror (15) rotatable about an axis normal to the plane, and a window (5) subtending at least a 90.degree. field of view and as much as a substantially continuous 360.degree. field of view in the plane. The window has a plurality of flat, parallel-surfaced panes (6) forming a polygon in the plane, each of the panes (6) having the same trapezoidal shape.

Abstract: For manufacturing printed products such as books or booklets consisting of a stack of paper sheets adhesively joined together and folded along a middle line, a plurality of paper webs are brought together to form a stack of paper layers moving continuously. Into the continuously moving stack a liquid binder is injected along equidistant lines perpendicular to the moving direction of the stack. After binder injection, two,additional webs are brought together with the stack to cover the stack on both sides. Then the stack is cut midway between each pair of junction lines to form individual stacks and the individual stacks are folded along the junction line.

Abstract: According to the inventive method for joining product parts by means of a glued spine, the juxtaposed edges of the stacked product parts which form the spine area (2) of the product in process are pre-treated with a tearing tool (4) e.g. with a rotating brush. The method is especially advantageous for joining multi-layer product parts with multi-layer folded edges to be joined, whereby the folded edges are torn up by the tearing tool (4) to a depth at least reaching the innermost layer. The inventive method is also applicable in the sense of stitching, for joining the individual layers of one single product part with one multi-layer folded edge.

Abstract: A contacting apparatus for interconnecting first and second groups of conductors has a first group of conductors lying in a plane parallel with a longitudinal axis. A first conductor is spaced a first distance from the axis. A second conductor has a first portion spaced a second distance from the axis, the second distance being greater than the first distance, and a second portion on an opposite side of the axis from the first portion and spaced from the axis by a distance equal to the second distance. The first and second portions are electrically connected together. A connection module has a second longitudinal axis and contact points for making electrical connections with the conductors of the first group.

Abstract: Sample bags are produced from webs of film material by forming longitudinal seams and longitudinally spaced transverse seams and by filling the bags with a sample product between forming the transverse seams. In order to make the bags easier to handle, the longitudinal seams are thickened so that the thickness of the seams is equal to the thickness of the center of the bag. Thickening is done by rolling or folding the seams or by adding frames or strips of additional material either between or outside the seam or interior portions of the webs. The resulting bags are more easily stacked, handled and inserted into publications for distribution.

The compact Converter Combiner MMIs of the invention make possible:1. converting a first fundamental mode into first-order modes,2. superposing the first-order modes and the images of a second fundamental mode,3. the MMI operates simultaneously as mode splitter for the participating modes.Back-conversion of the generated modes of higher order into their initial modes also is possible.

Abstract: A sequence of documents is delivered to an optical scanner in which each document is scanned to form a digital image representation of the content of the document. The image representation is automatically examined by data processing apparatus to select search words which meet predetermined criteria and by which the document can be subsequently located. The search words are stored in a non-volatile memory and the entire document content is stored in mass storage in image form. A font table is established and images of entered search words are constructed from the table. Unrecognized or imperfectly formed ambiguous characters are stored with the font table and are used in the construction of search words to ease or eliminate text editing or are stored with converted characters of search words. The approach can also be used to ease or eliminate editing of full text-converted data bases during input.

Abstract: A suction device for handling light, flat and bendable articles has a suction line and a sucker at an end of the suction line. The sucker has a suction lip made of an elastically deformable material for individually contacting and lifting articles. A lip-deforming bending template having a deforming edge defining a concave shape is displaceable relative to the suction lip so that the suction lip is deformed by contact with the deforming edge to conform to the concave shape. A second bending template can be laterally spaced from the suction lip and have a bending edge for contacting an article lifted by the suction lip, the lip being displaceable relative to the bending edge.

Abstract: An instrument for performing a correctional osteotomy of a lower extremity of a patient has a securing frame (1), fixation elements (7, 8) for attaching the frame to the skeleton of the lower extremity of the patient, and securing components (6, 9) adjustably holding the fixation elements on the frame. A saw guide (25) is mounted on said frame so as to be angularly adjustable relative to the frame. An angle-indicating scale plate (10) is adjustably attached to one of the securing components. A rotation axis pin (12) penetrates the scale plate and points toward a location on the skeleton for intersection of bone cuts to be made. An angle determining component (23) is pivotable about the rotation axis pin and carries the saw guide and two pointers (26, 27) aligned with each other and alignable with a projection of a mechanical loading axis of the extremity of the patient, whereby adjustment of the pointers directly causes adjustment of the saw guide.

Abstract: A nomographic apparatus for providing solutions to a mathematical relationship has a panel and several scales along three axes on a surface of the panel, the scales being arranged and calibrated in a nomographic relationship so that values on a straight line intersecting the scales satisfy the mathematical relationship. Guides are adjacent two selected ones of the scales, the two selected scales being separated by at least one other scale. First and second sliders are movable along the guides and strings extend between the sliders in substantially straight lines. The first and second sliders are positionable so that the strings intersect first and second locations on the selected scales, the locations representing selected numerical values of the mathematical relationship. As a result, a third value of the mathematical relationship is readable adjacent the other of the scales.
