Title: Opthalmic test appts. control switch - with preselector, and state comparison to produce control signals
Inventor: BOENIG GUENTER
IPC: A61B3/032
Filed: 1973-10-12
Abstract: Test selection switch a preselector is for control of opthalmic test appts.; the control conductor for the respective direction of running, also used when the hand switch is used, is connected for a period corresp. to one of the number of further tests to be switched to, continuously or pulsewise. The signals for control of the further tests (forward and return signal) is produced by comaprison of the state of a preselector before, and the state after, altered setting of the preselector in the test selection switch. Preferably, for control of the test setting, the voltage or current pulses on the control conductors are counted as positive or negative, corresponding to the running direction of the tests, and at a given difference, pref. zero (equality) between the counter state and the preselector, the desired test is reached, and the contacting for control is ended. The switch can be connected instead of the hand switch witout further modifications of the appts.

Title: Degassing system for liquid flowing through a pipe - makes use of throttle consisting of armature with labyrinth grooves
Inventor: KALB HANS
IPC: F16K24/06
Filed: 1974-10-24
Abstract: If gas is present in a liquid flowing through a pipe-line system, the pressure of the liquid will drop more than the pressure of the gas when it passes through a resistance. The larger the viscosity of the fluid, the larger the pressure difference. Use is made of this difference in pressure drop to separate the gas from the liquid. The armature used to separate the gas consists of a piston which can move in a cylinder, and which is connected by a stem to a valve. Piston, valve and cylinder are mounted in a housing. A bore passes through valve, stem and piston. The bore at the valve end is reduced to form a choke path.

Title: Continuous mfr of optical cable - where waveguides are mounted on plastic core and surrounded by welded metal pipe
Inventor: TSCHARNTKE DETLEF ING GRAD
IPC: G02B6/44
Filed: 1975-02-19
Abstract: Optical cable for data transmission, where the optical wave guides are mounted on a cylindrical core and the assembly shrouded by a protective sheath. The novelty is that the waveguides have an excess length when located on the core, and are covered with a plastic foil provided with overlapping longitudinal side webs; and that the assembly of core, waveguides and foil is located in a strong metal pipe leaving a space between the core and the inside wall of the pipe. The core is pref. made of plastic contg. a central reinforcing element, and alternative designs for the cable are included in the claims together with a process and device for mfg. the cable. The metal pipe protects the optical waveguides from tensile and bending stresses and also from temp. fluctuations; as the wave guides are longer than the core they are not subjected to tensile stresses if the core is stretched.
