Title: Unlimited polarisation adjustment for optical heterodyne reception - transmitting relatively weak additional signal with orthogonal polarisation to receiver capable of maximising useful signal
Inventor: DAS CHANDAN
IPC: H04B10/64
Filed: 1992-11-17
Abstract: The transmitter of phase-shift-keyed signals incorporates a transmitting laser (SL) with a 2 x 2 optical fibre coupler (K1) for division of the emission into two orthogonally polarised components. The sec. connections feed a PSK modulator (M) supplied from a source (NS) of useful signal, and a frequency-shifter (FS) attached to an additional signal generator (ZSG). A second coupler (K2) provides polarisation recombination to obtain at the output (SSA) the useful signal together with an orthogonally polarised component corresp. to the additional signal. ADVANTAGE - High-speed adjustment over extended range of allowable polarisation variations on coherent optical transmission path is combined with greater precision.

Patent DE-4309351-A1 (DE)
Inventor: REIME GERD
IPC: H04N5/14
Filed: 1993-03-23
Abstract: A fading device (12) which is connected to the output (11.2) and to the input (11.1) of a delay line (11) contained in the transmission path (9) is connected into the transmission path (9) of an equaliser arrangement (8) for a signal (Se) which exhibits signal discontinuities. In addition, the input of the transmission path (9) is connected to a control arrangement (14) for detecting signal discontinuities, which, when a signal discontinuity is detected, generates a control signal S14 which oscillates about a zero line and exhibits a zero crossing and which controls the fading device in such a manner that an associated signal edge occurring at the time of the signal discontinuity is transmitted with a steep slope. Outside the detection of a signal edge, both a component of the undelayed colour signal and a component of the delayed colour signal is transmitted to the signal output (12.3) of the fading device (12).

Title: Method for eliminating bacterial DNA from thermally stable DNA polymerase using a DNA-digesting enzyme
Inventor: MAIWALD MATTHIAS DR
IPC: C12Q1/689
Filed: 1993-04-30
Abstract: Technical problem> In the method of the polymerase chain reaction it is possible , owing to the DNA present in the required thermally stable enzyme due to its preparation, for there to be adverse effects on the test results in certain applications. The novel method is intended to make it possible to eliminate the DNA from the thermally stable enzyme in a simple and efficient manner. Solution of the problem The thermally stable DNA polymerase is treated with a DNA-digesting enzyme in an alkaline medium containing magnesium chloride, and subsequently the digesting enzyme is inactivated. Moreover a division of the reagents required for a polymerase chain reaction takes place so that the primers consisting of DNA are added only after the pretreatment. Areas of application The described method makes it possible to eliminate bacterial DNA from a thermally stable DNA polymerase employed for the polymerase chain reaction in a simple manner and thus makes it possible to use the polymerase chain reaction for efficient screening for unknown bacterial pathogens.

Title: Cantilever shelf for sales stands, shelf units or the like
Inventor: STENEMANN BRUNO
IPC: A47B96/02
Filed: 1993-07-09
Abstract: The invention is directed at a cantilever shelf which comprises a holding frame and a plate carried thereby. The holding frame is composed of a front-side and a rear-side longitudinal bar, the bar ends of which are connected by the crosspieces. In order to ensure universal usability of the shelf, it is proposed to couple the plate both at its front-side and at its rear-side longitudinal side via a releasable push-in connection to profiled edge strips which bound the supporting surface of the plate on both longitudinal sides and form a pre-assemblable construction unit with the plate. When assembled, this construction unit is supported merely by its edge strips on the two longitudinal bars of the holding frame.
