Title: Multiplexer or demultiplexer optical element - is transparent block containing light guide loop intersected by sloping filter and having output surface
Inventor: WINZER GERHARD DR ING
IPC: G02B6/28
Filed: 1980-03-03
Abstract: The branch element for a light guide system has a transparent block (3) divided into two by a sloping plane (4). The block also has a light guide (2) embedded in it, forming a loop, which is also intersected by the plane. Onto the sloping surfaces is deposited an edge filter (6), which emerges at a flat polished face (7) of the block. The distance (a) between this face and the outside of the light guide is very small. When the element is used as a demultiplexer, a bandpass filter (8) is deposited on the face over the region of the edge of the filter. A line (9) of photodetectors can be mounted against this region with detector surfaces (10) attached by an optical adhesive. The photodetectors can be formed by a monolithic integrated circuit. Alternatively, this surface carries a bandpass filter for a further light guide projecting from it, inside a mounting block.

Patent DE-3042763-A1 (DE)
Title: Digital transmission over telephone cables - using subdivision into parallel part signals sent over separate core pairs at reduced bit rate
Inventor: BRAUN FRIEDRICH
IPC: H04L25/14
Filed: 1980-11-13
Abstract: The digital signal to be transmitted from one exchange (E1) is sub-divided into part signals by a converter (W1), and sent in parallel mode to the exchange at the other end of the line (E2). Here the same converter system (W2) recombines the part signals into a serial signal for further use. The parallel transmission speed is considerably slower than the speed necessary for the equivalent series signal transmission. The proposed system does however require one pair of cones for each parallel part signal as against one pair only for serial transmission. The lower rate leads to lower attenuation and hence to fewer, or even no, repeater stations along the line.
Patent DE-3104033-A1 (DE)
Title: Process for the production of ethylene glycol
Inventor: MATSUDA AKIO
IPC: C07C41/00
Filed: 1981-02-05
Abstract: The invention relates to a novel, very economical process for the industrial production of ethylene glycol from formaldehyde and synthesis gas, i.e. a gaseous mixture of carbon monoxide and hydrogen. The process is based on a synthetic route in which a formaldehyde di-s-alkyl acetal, which is obtained from formaldehyde and a secondary alcohol, is reacted with carbon monoxide and hydrogen to give an ethylene glycol mono-s-alkyl ether, which is then hydrolyzed with water to give the desired ethylene glycol. The first reaction step of the reaction of the acetal compound is catalyzed by cobalt carbonyl as a single component catalyst, while the hydrolysis reaction is carried out using an acidic catalyst; a high yield is obtained according to the invention, which is surprising in respect of the analogous reaction of primary alkyl monoethers of ethylene glycol.

Title: Process and apparatus for removing undesirable gaseous constituents from a hot exhaust gas
Inventor: LINDE GERHARD DR ING
IPC: B01D53/86
Filed: 1981-04-29
Abstract: In a process for removing undesirable gaseous constituents from an exhaust gas, containing sulphur dioxide or other impurities, from combustion, the exhaust gas is cooled and scrubbed by an absorbent selective for sulphur dioxide. To remove nitrogen oxides which are contained in the exhaust gas, ammonia is added to the exhaust gas before scrubbing and the resulting gas mixture is passed over a catalyst. The nitrogen oxides are reduced in the course of this. The catalyst packing is expediently situated at the hot end of a regenerator for cooling the exhaust gas and is arranged on the regenerator charge.
Patent DE-3118671-A1 (DE)
Title: Device for generating a signal sequence with adjusting duty ratio from the periodic voltage of an inductive transmitter arrangement particularly for controlling ignition systems
Inventor: FRITZ ADOLF R
IPC: H03K5/156
Filed: 1981-05-12
Abstract: The transmitter voltage (U10) is supplied to two threshold stages constructed as comparators (24, 13), the threshold value of one comparator (13) being variable under voltage control to adjust the duty ratio. This is done by the fact that this comparator (13) in each case predetermines the first edge of a signal sequence whilst the in each case second edge is predetermined by the second comparator (24). In this manner, one edge can be shifted for changing the signal length without the second edge also shifting. This is of particular importance for ignition systems in which an angular extension of the closing time should be produced with increasing rotational speed without the ignition time predetermined by the back edge also shifting. <IMAGE>
