Patent DE-4102643-A1 (DE)
Inventor: WEISSERT HERBERT
IPC: G02B6/122
Filed: 1991-01-30
Abstract: Optical isolators suppress the retroreflection of light. According to the invention, light coming from a first optical fibre (2) is transmitted on a substrate (1) into a second optical fibre (3) at an acute angle in the region of an optical filter. The first (2) and the second (3) optical fibres do not touch one another. Present in the latter is a quarter-wave plate (7). The light in the first optical fibre (2) is electrically linearly polarised in a plane that is coplanar with the surface of the substrate (1). Since light of this direction of polarisation is very much less attenuated upon passage between the optical fibres (2, 3) than is light which is electrically polarised perpendicular to the surface, the light retroreflected after passing through the quarter-wave plate (7), which light has precisely this direction of polarisation, is almost completely suppressed in the first optical fibre (2). The optical isolator can also be used in an interferometer. <IMAGE>

Title: Equipment for speech control of appts. - in which spoken command produces electrical measurement signal, with signal analysed and compared with sample signal for command
Inventor: SEEMANN NIKOLAUS VON
IPC: G10L15/22
Filed: 1991-02-08
Abstract: A microphone (2) converts the spoken command into electrical signals. A processing circuit produces measurement signals out of the electrical signals. A microprocessor (8) analyses the measurement signals and compares them with simple signals for the command. The microprocessor emits a control signal at an outlet. In a comparison circuit the amplitude of the measurement signal is compared with a reference voltage. At its outlet a logic 1 situation is present if the measurement signal exceeds the reference voltage. A logic 0 situation applies if the amplitude of the measurement signal is below the reference voltage. The microprocessor is used to compare the time pattern of the measurement signal at the outlet of the comparison circuit with a time pattern of a stored sample signal. When there is coincidence between the time patterns of both signals, the microprocessor issues a control signal at an outlet (10). ADVANTAGE - The control of appts. by spoken command.

Patent DE-4114190-A1 (DE)
Title: Bar feed for bar peeling and finishing line - has bar feed rolls with automatically adjustable inclination, so that bar can feed axially without rotation
Inventor: LINDEMANN HANS
IPC: B23B5/12
Filed: 1991-05-01
Abstract: Immediately before and after the bar peeling machine are bar feed roll assemblies with roll axes inclined to impart a combined axial and rotational movement to the bar in its passage through the peeling cutter head. The second bar feed may form part of a bar straightening machine. To avoid damaging the surface of the peeled and polished bar, it is fed out of the machine line by a draw carriage which has jaws gripping the bar. Just before the bar is gripped, the inclination of the feed rolls is automatically reduced to zero so that the bar stops rotating and only moves forward axially. The rotational speed of the feed rolls is synchronously regulated to maintain a constant axial bar velocity. ADVANTAGE - Simple draw carriage without means for rotating the bar can be used.

Patent DE-4203157-A1 (DE)
Inventor: JEROMIN LUTZ DR
IPC: C07C31/22
Filed: 1992-02-05
Abstract: In the method described, the glycerin water (fresh water) produced in the high-pressure decomposition of natural fats and oils using steam to give fatty acids and glycerin is continuously purified. Using a plate-type phase separator, fatty-matter droplets with a diameter greater than 100  mu m are separated from the aqueous phase and fed back to the high-pressure decomposition stage. The aqueous phase pre-purified in this way is then passed as a cross-current flow over a filtration membrane, in particular a microfiltration membrane, and the concentrate fed back to the phase-separator input. This method enables large, industrial-scale quantities of glycerin water to be purified efficiently and particularly inexpensively on a continuous basis, even when the source of supply changes frequently.

Patent DE-4205301-A1 (DE)
Inventor: SCHWEIZER KURT
IPC: G03F5/00
Filed: 1992-02-21
Abstract: The invention relates to a multiple assembly register system which facilitates the production of even large assemblies with the aid of predetermined register standards in such a way that the assembly positions selected can be locked or stored highly precisely and flexibly. A preferred assembly device consists of a horizontal assembly board above which four separate positioning heads (15) can be taken to any desired position by means of an X-Y slide system (11, 12, 13). On the underside of each positioning head (15) are secured register strips (16) of a predetermined register standard. The multiple assembly register system of the invention makes it possible to assemble four DIN A4 double pages (I-IV) of a colour assembly substantially parallel. The positioning heads (15) are locked in their positions so that the printing master films for subsequent colour assemblies can be fitted in exactly the same position on further assembly base foils without any subsequent matching.

Inventor: BHATNAGAR SATPAL
IPC: B05B15/12
Filed: 1992-07-08
Abstract: The air supply system has a fresh air channel leading to the line, and a waste air channel leading away from it. A heat exchanger between the two cools the waste air and heats the fresh air. The heat exchanger (28) has a rotating exchanger rotor (30) with an internal exchanger structure (38).
