Title: Process for increasing the effective opening ratio of liquid crystal light valves
Inventor: LEI FANG DR ING
IPC: G02B5/00
Filed: 1993-09-25
Abstract: It is known to use a microlens array to increase the effective opening ratio. By means of this process, it is not possible to use 100 % of the effective opening ratio. It is the object to increase the effective opening ratio of liquid crystal light valves. This object is achieved in that, instead of the microlens array, an optical fibre array is used. In this case it is advantageous that, as a result of the total reflections, an effective opening ratio of 100 % is achieved. Especially for projection television and projection video. <IMAGE>

Title: Crane wheel design with contact well clear of rail edge
Inventor: WINTER KLAUS-JUERGEN DIPL ING
IPC: B66C9/08
Filed: 1994-06-24
Abstract: Alongside its point of rail etc. contact (6), the wheel profile (8) is curved to dissimilar radii (R1,R2) so as to work with conical opposing surfaces (4a,4b) of surfaces running parallel to the wheel axis (1a). The centres of the profile curvature (9) are arranged so that the contact points of the wheel stand at equal distance (11) from the outside edge (7) of both conical and wheel-parallel opposing surfaces. The point of wheel contact stands equi-distant between the roller bearings which support the wheel. In detail, the wheel running surface (3) conforms to the opposing rail etc. surface so the load and curvature give rise to a defined contact area (5) and contact point (6) maximally spaced from the outside edge (7) of the rail. The wheel profile with its differing degrees of curvature can work with conical or parallel opposing surfaces as involved, so that the intercept (A1) for a parallel surface lies below the wheel diameter (D) at a centre point (9) for offset angle ( beta ), as against intercept (A2) for a conical rail etc. surface where the centre of curvature (11) lies on a diameter (D) normal to axis (1a) at radius (R2).

Title: Gas=tight joining of pipes having small diameters and different melting points
Inventor: WIELAGE BERNHARD
IPC: F16L13/08
Filed: 1994-10-14
Abstract: When the solder surround zone is heated to soldering point both solder and pipe material heat quickly to join the pipes whilst the soldering temperature is retained. Pipe end (2) is mechanically plugged into the mandrel-expanded end of the lower-melting Al pipe (1) for the solder join. The Cu pipe (3) is then expanded and inserted into the Al pipe so all three pipes can be soldered together. The inside surface of the end-expanded Al pipe is thus intimately joined by the solder to the non-expanded outsides of the Cu pipe. Preferred soldering temperature is 600 deg C, the flux operating within a range 400-700 deg. C and the projecting damper plate connection is joined to the Cu pipe (8) pref. in a single pass. Typically the Cu pipe acts as capillary (3) to fit with pipes (2) into the flared end (1) of the Al pipe.
