Title: System for scanning a surgical laser beam
Inventor: FOUNTAIN WILLIAM D
IPC: B23K26/08
Filed: 1991-08-08
Granted: 2002-09-17
Abstract: In a laser beam delivery system for a surgical laser beam, steering and scanning of the laser beam along the target (20) in transverse (X and Y) directions is accomplished in a mechanically simple and fast-responding manner. Closely adjacent to the objective lens assembly (24) of the delivery system is a pair of prisms (12, 14), i:e. Risley prism Ar Herschel prism; positioned on the axis (16) of the approaching laser beam (18). The two prisms are mounted on separate rotating stages whereby they may be individually rotated about the beam axis. Co-rotation of the prisms produces circular scans, in diameters depending on the angle between the prisms. Counter rotation of the prisms at equal speeds will produce a diametric line scan. Any desired complex scan pattern can be achieved using combinations of rotations of the prisms. Axial compactness and proximity to the objective lens as-sembly assure that virtually all of the angularly emerging beam from the prism pair passes through the objective lens assembly.

Abstract: In this command and signal apparatus a cap (2) which comprises a shoulder carrying an annular diaphragm (3) at the side of the user appears through an opening of a cover plate (1). Displaceable arranged in the cap (2) is an acknowledgement element (4) with a hollow-cylindrical head part, a first guide, a second guide and a push rod. A sleeve (13) can be advanced, by way of a thread (12) extending at the circumference of a switch carrier (11), so far until this, together with the shoulder of the cap (2), forms a firm seat with the cover plate (1). Provided at the rearward end of the switch carrier (11) are board holders (14), which carry a second circuitboard (15) on which is arranged a microswitch (16) actuated by the pushrod. Arranged in the head part of the acknowledgement element (4) is an annular light conductor (18), which stands in connection with a first circuitboard (17) and which conducts the light from light-emitting semi-conductors integrated on the first circuitboard (17) to the underside of a glass pane closing off the command and signal apparatus at the front side. The light-emitting semiconductors are regulated by means of photo semiconductors in dependence on the ambient light, so that the light ring visible on the glass pane (19) lights up brighter the brighter the ambient light is. A flexible mufti-wire line (21) connects the first circuitboard (17) with the second circuitboard (15) by way of solder points (22) and plug contacts (23).

Title: Bio specifically recognizing surfaces on solid supports and method for their preparation
Inventor: BARNER RICHARD
IPC: G01N33/543
Filed: 1993-06-22
Granted: 2004-11-02
Abstract: The biologically recognising layer on a solid phase consists of biologically recognising molecules comprising regions which recognise (bond) the substance to be analysed and regions which do not recognise (do not bond) the substance to be analysed.      The biologically recognising molecules are aligned on a suitably modified surface by means of molecular regions which do not recognise the substance to be analysed. The biologically recognising molecules are cross-linked with the aligning surface and are consequently covalently altered. The molecular regions recognising the substance to be analysed are not altered by the covalent bonding and retain their bonding activity.      The layer is produced in a novel two-stage method. In the first step, the biologically recognising molecules, the aligning molecules and the carrier molecules are adsorbed. In the second step the molecules are covalently anchored by cross-linking. Cross-linking is brought about by photolytic activation of the reagent bonded to the carrier molecules.      Even after reacting with the earner molecules the reagent contains water-solubilising groups.

IPC: C03B23/03
Filed: 1992-11-25
Granted: 2003-02-11
Abstract: A method of and apparatus for establishing a predetermined thermal profile in a glass sheet immediately prior to press bending outside the heating furnance (12). The press bending members (26, 27) are provided with arrays of heating elements (70, 76) that are individually or zone regulated to assist in establishing an optimum temperature profile in the glass sheet conducive to proper bending. The temperature profile established in the heated sheet by the arrays of heating elements (70, 76) is coordinated with that established in the furnace (12) and subsequently, modified by heat dissipation as the glass sheet advances to the bending station (13) to achieve the proper bending temperature. The heating elements (70, 76), can also be utilized to create a temperature profile in a glass sheet generally higher than that originally established in the furnace (12). The sheet can be held in contact with one or both of the heated press members (26, 27) for a brief period of time after bending to slow the cooling rate of the sheet and increase the edge strength of the marginal edge area thereof.

Granted: 1999-05-04
Abstract: Cr is included in an Al-Si alloy plating layer formed on the steel sheet by hot-dip coating, to improve corrosion and heat resistance.   A Cr layer preformed on the steel sheet by vapor deposition, electroplating or the like is used as a Cr source to the plating layer.  When the surface of the Cr layer is activated by plasma or ion beam etching before the introduction of the steel sheet into a coating bath,  the Cr layer shows good wettability to a coating metal.  A plating layer L formed on the steel substrate S has a multi-layered structure composed of the first sub-layer L1 of Cr, the second sub-layer L2 of a Cr-Al-Si alloy and the third sub-layer L3 of an Al-Si-Cr alloy.  Since the plating  layer  L  contains  Cr,  an  obtained  product  is remarkably improved in corrosion and heat resistance as compared with a  conventional Al-Si-  alloy-coated  steel sheet.

Abstract: The epicyclic gear train consists of a driving shaft and pinion (1,3), satellite pinions (4), unidirectional crown wheel (7) and clutch (14,15). The clutch operates between the crown wheel and a satellite bearer wheel (5) attached to the output shaft (6). At high speeds increasing centrifugal force acting on plates (31) opens the clutch, lowering the gear ratio which is restored to direct drive at lower speeds. Heavy accelerator pressure operates an electromagnet (123,124) which delays clutch opening as does high input torque through an axial force (FAC) at the helicoidal gears (7). <IMAGE>
