Title: Cerebral probe for contacting single cells - has retractable point electrode in gold cap, with ferrite base attracted by solenoid
Inventor: KOCH RAINER ING GRAD
IPC: A61N1/05
Filed: 1979-07-03
Abstract: This cerebral probe can access individual brain cells for monitoring electrical signals without risk by using a retractable point electrode within a gold cap. The electrode protrudes only about 50 micrometers and therefore cannot puncture any tissue. A thin tube (E) holds a micro-electrode (M1) and pre-amplifier chip (VV), and has a ferrite base (FE). When operated, this ferrite base is attracted by a solenoid (SP) thus pushing the bi-polar electrode (M1) through an opening in the gold cap (G). This movement is limited by the gap between the ferrite plate assembly and the base (K) of the outer probe housing.

Title: Glass optical waveguide fibre with rectangular cross=section - which precludes the coupling of two light waves with orthogonal directions of polarisation
Inventor: HUBER HANS-PETER DIPL PHYS
IPC: C03B37/014
Filed: 1979-07-28
Abstract: The fibre is pref. used to carry monochromatic light; and the refractive index (RI) of the fibre is not rotationally symmetrical w.r.t. the radius of the fibre. The fibre is made from a blank with a rectangular cross-section; and the blank is made from a substrate with a rectangular cross-section. The substrate is coated with one or more layers of glass, and/or the doping concn. may be varied in the glass layer(s) and/or in the substrate. The substrate pref. has a higher RI than the deposited glass layers and forms the core of the draw fibre. Alternatively, the substrate may be removed after the deposition of glass layers, which are then collapsed to form the blank. When two waves, which are polarised at 90 deg. w.r.t. each other, travel through the fibre they have markedly different dispersion speeds and wave numbers, so no coupling occurs between the two waves.

Title: Pressure diffusion sepn. method for mixts. - uses perpendicular identical frequency wave fields with differing phases
Inventor: BSCHORR OSKAR DIPL ING DR
IPC: B01D59/50
Filed: 1980-07-19
Abstract: The sepn. of mixts. of two gases, two liqs., a gas with a colloid, or a liq. with a solid, and based on differing molecular weights or specific gravities is effected by pressure diffusion using varying pressure fields. These fields are two-dimensional mutually perpendicular wave fields operating at the same frequency but with pi/2 phase shift. The mixt. for sepn. is fed by co-current or counter-flow perpendicular to the vibration plane along the longitudinal axis of a prismatic sepn. chamber with the sepd. components leaving at the roof of the chamber. The wave-fields can be formed by two vibrating walls, each tuned to the natural frequency of the standing waves. A circular polarised wave field produced by a single vibrating wall and reflecting wall, or by tubular valves, may be used. The method separates a variety of mixtures, in particular gaseous isotopes, with high efficiency and low power consumption. No moving parts or pressure compressors are involved.
