Patent DE-3826694-A1 (DE)
Inventor: MELCHIOR FREDERIC BERNARD
IPC: G02B23/12
Filed: 1988-08-05
Abstract: Two collimators 11, 12, provided with point sources (C1, C2 Fig. 3), are arranged to project two beams 53, 54 symmetrical in relation to the line of sight OX, into the periphery of lens 6 of the optical system. The position of the line of sight is determined by determining the midpoint of the segment joining the images I1, I2 of the point sources formed by the lens, and the scaling factor by determining the length of this segment. The angle e1+e2 of the beams being constant by design is therefore known. Determining the position of the line of sight is not dependent on any focussing error. Each of the beams can be duplicated to determine the scaling factor after eliminating the focussing error. The invention can be applied to thermal cameras. <IMAGE>

Inventor: BAUMANN ROBERT
IPC: C22C32/00
Filed: 1988-12-09
Abstract: Method for the production of a workpiece composed of a nickel-based superalloy hardened by oxide dispersion and consisting of a single crystal with a preferential longitudinal direction starting from a fine-grain extruded feed stock by cutting it out of the latter and then zone-annealing the workpiece, such that the direction (2) of extrusion encloses in the workpiece (3) an angle  beta  of 0 to 60@ with the recrystallisation front (7), which lies essentially in the plane of the induction coil (8) of the heating device for zone-annealing. Variant: in a first zone-annealing process, only a part of the workpiece situated on the narrow side is converted into a single crystal and, in a second, conventional zone-annealing process, this is forced to grow into the remaining fine-grained part. <IMAGE>

Title: Coin number control device for coin wrapping machine - numbers and counts coins in coin stack using absolute valve rotational adjuster
Inventor: MIYAMOTO KATSUYUKI
IPC: G07D9/06
Filed: 1990-02-26
Abstract: The appts. controls the number of coins in a coin stack (1) in a coin packaging machine. Packing rollers serve to wrap packing tape (3) around a preset number of stacked coins. This is broader than the height of the stack of coins, so that a fold-in section of the packing tape protrudes above and below the stack of coins. The coin packing machine protrudes above and below the stack of coins. The coin packing machine also has a top (6) and bottom (7) srapping claw. These can be moved vertically towards, or away from, each other and are moved towards each other into a position for wrapping in the fold-in sections of the wrapping tape, clamping the pile of coins between them. The appts. also has a top carrier arm (8) carrying the top wrapping claw, a bottom one (9) for the bottom claw, a vertical cog-rail (12) fixed to one of the carrier arms and a turnable pinion (13) set in the other carrier arm and synchromeshed with the cog-rail. An absolute value rotational adjuster (14) linked to the pinion identifies position absolute values separately from the turning position of the pinion. A detector controls the number of coins in the stack of coins by calculating the sum of the distances covered by the top and bottom wrapping claws, based on the position absolute values produced by the rotational adjuster output of which is connected to a measurement value memory with a display.

The processor also controls the servo steering effect on the rear-and front wheels. If servo steering is applied to the rear wheels, when conditions require, then the front servo effect is correspondingly reduced. ADVANTAGE - Improved control, adaptable to different road/driving conditions.

ADVANTAGE - Automatically sets relationship between instantaneous measurement value and associated detector-surface-distance so that, independently of the instantaneous distance, a value is displayed related to a selected distance.
Patent DE-4012478-A1 (DE)
Inventor: ROTHE ECKHARD
IPC: G02C7/04
Filed: 1990-04-19
Abstract: Contact lenses having position stabilization are utilized in order to fix the position of the contact lens on the cornea of the eye of a person wearing the lens. For this purpose, thickened regions for adjusting a specific orientation relative to the eye of the wearer are provided on the convex outer surface of the contact lens outside of the optical zone. A reliable position stabilization of a contact lens on the eye is achieved in that at least two thickened regions are provided laterally of the vertical center axis. These thickened regions extend essentially below a horizontal center axis between the optical zone and the edge region and it is very advantageous if these thickened regions lie at least at one point on the lower eyelid when the eye is open. In this way, a rotation of the contact lens is avoided when the eye is open. Furthermore, it is advantageous when the contact of the thickened regions on the lower eyelid is maintained. Additional thickened regions can be provided on the outer surface by which the movement of the upper eyelid encounters resistance when moving downwardly. These additional thickened regions are arranged above the first-mentioned thickened regions. With this combination, an optimal position stabilization of the contact lens on the cornea of the eye is achieved. The possibility is also presented that the thickened regions can be configured that they provide static as well as dynamic position stabilization.
