Title: Deformable mirror e.g. for focussing laser beam - has fixing collar of shape-memory alloy, attached by radial forces at one temp. and released at other temp.
Inventor: BRILL MICHAEL
IPC: G02B26/08
Filed: 1992-03-04
Abstract: The deformable mirror consists of a mirror plate (12) with a boss (24) on its rear surface to attach it to an actuator (28) which applies a force to the mirror, changing the focus of a laser beam impinging on the mirror. The actuator contains a number of piezoelectric elements (28) connected in parallel. Liquid nitrogen coolant enters and leaves the device by channels (46,48). The mirror (24) is fixed to the actuator by a fixing collar (54). This is made from a Nickel Titanium alloy (NiTi) which undergoes a change in crystalline structure from austenitic to martensitic with temperature. With a change in temperature, the dimension of the collar switches from diameter D1 to D2. To release the mirror for exchange, liquid nitrogen coolant is supplied to reduce the temperature of the collar to -150 deg.C. To fix the replacement device, a heating current is applied to heater (58) to raise the collar temperature to 150 deg. C. The collar switches state (constrained recovery) to shrink in place, holding the mirror firmly. ADVANTAGE - Simplified exchange of actuator.

Inventor: BAUER HEINZ DIPL PHYS DR RER N
IPC: C07C7/11
Filed: 1992-05-27
Abstract: The invention concerns a method for the production of light C2+-hydrocarbons, in particular ethylene and ethane, from cracked gas, in particular from a gas produced by a fluid catalytic cracking process.

Title: Thermal print head with mechanism for head access - has head mounted on lever arrangement with eccentric element turned to effect release
Inventor: KOCH ULF
IPC: B41J2/325
Filed: 1992-06-17
Abstract: The thermal print head has a head unit (3) mounted on an arm (2) that is pivot mounted on a fixed spindle.

Patent DE-4229313-A1 (DE)
Inventor: WURBS GUIDO DIPL PHYS
IPC: G01S17/89
Filed: 1992-09-02
Abstract: In order to measure chiefly the roughness of surfaces, the invention proceeds from the triangulation method by means of a laser, in which the angle between the surface and the measurement beam can be adjusted. The light spot produced on the surface must be smaller the more accurate the resolution is to be. In practice, in these regions interference phenomena occur which, acting as speckle, disturb the measurement signal through noise, The invention substantially improves the extent to which the received signals can be evaluated by virtue of the fact that the light bundle reflected/scattered by the surface is resolved optically, as a function of the angle, into two component bundles having approximately the same area distribution of intensity transverse to the principle beam direction, and that the two light bundles are then detected by photodiode and the roughness characteristics are determined from the signals. <IMAGE>
