Title: Gas laser for welding or cutting - using crosswire and telescope to align laser beam
Inventor: HEINE PETER
IPC: B23K26/14
Filed: 1975-06-26
Abstract: Gas laser, esp. for processing materials, uses a resonator contg. a fully reflecting mirror and a partly transparent outlet mirror on a common axis. The novelty is that at least one crosswire is provided on the optical axis of the mirrors. The resonator pref. uses a folded discharge tube with two deflection mirrors, the crosswire being located in front of the deflection mirrors or replacing the concave reflector. Instead of the outlet mirror, a measuring telescope can be located on the laser axis and used as a levelling instrument. The crosswire is pref. located on or in a disc which is transparent to light. Accurate alignment of the discharge tube with the mirrors is obtd. so any distortion due to the mirrors can be eliminated. The power output can reach 10 MW/cm2.

Title: Automatic tuner for resonant circuit - tunes in one step by comparing actual tuning with preset required tuning
Inventor: HERZAN HANS ING
IPC: H03J1/18
Filed: 1975-12-31
Abstract: The automatic tuner, for resonant circuits, has frequency counters and constructs the difference between the actual tuning and the requiring tuning entered into the tuner in order to effect tuning as quickly as possible in one step. The required tuning is denoted by a d.c. voltage and the tuning process itself is electronic. This d.c. voltage is set by moving a mechanical device. For tuning over a large frequency range, additional signals can be employed to set the waveband. The electronic setting enables a finer tuning to be achieved than is possible by hand.

Title: Decorative transparent fluorescent plate - is bevelled along edges and has sloping mirrors inset, or stacked, for contrast effect when illuminated
Inventor: GRUENKE KARL
IPC: B44C5/04
Filed: 1976-08-03
Abstract: Fluorescent strip or plate material using e.g. acrylic glass can be given an improved decorative effect by bevelling the edges.

A decorative pattern can be formed merely by cutting a groove, e.g. a triangular groove in the face of the sheet. Grooves of alternative cross section can be coloured differently for a multi coloured pattern. A slot can be cut at an angle for insertion of a reflective strip. A large slot can be cut to accommodate a neon tube, or a hole borer through the middle to hold the tube.

Title: Flame hardening inner surface of pump housings - to increase working life in dredging and similar operations
Inventor: SILLER VINZENZ
IPC: C21D9/08
Filed: 1976-12-13
Abstract: The inner surface of a pump housing, which may be clad, is continuously flame hardened with or without altering the properties of the core of the material. The housing is laid horizontally and rotated on a vertical axis so its bore travels past a stationary burner located in the housing and the houding can also be tilted out of its horizontal position to drain the water employed in quenching the flame heated zone. As an alternative, the burner can be rotated in the pump housing. Pref. plant includes a turntable which can be rotated and also tilted on a machine bed. The pump housing is placed on the turntable; and a burner is mounted on a pipe located on the vertical turntable axis so the burner flame heats the bore of the housing. Pressurised water is fed onto the outside wall of the pump housing for quenching, in addn. to water fed into the bore of the housing. Used to increase the working life of pump housings used e.g. on dredging machines.

Title: Centrifuge rotor for washing blood cells - has two formed components between which films are mounted
Inventor: BAEUMLER JUERGEN
IPC: B04B5/04
Filed: 1976-12-24
Abstract: Centrifuge has rotor made from two parts which together form a series of chambers made from inert plastic to take blood samples. The containers consist of two film liners or a blown up profile following the contours of the upper and lower parts of the rotor. When these are jointed together, the passages, channels and chambers are formed. In the rotor centre is a coupling with a rotatable feed point which forms a connection to the internal vessels. The input branch for blood and wash liquor lies opposite that for liquor run off. A sepg. film is mounted between the two, joined by flexible components. The upper inlet part leads into a passage feeding to the outer edge of the chambers while the lower outlet ones lead from the inner edge of the chambers. Used for preparing blood cell specimens by washing blood samples. Arrangement gives a long life to the centrifuge components with higher operating speeds, and hence improved prod. purity.
