A line network communication system transmits coded data signals on a base band carrier signal and includes a receiver capable of recovering the coded data signals from transmitted signals. The receiver operates in a search mode initially, in which a series of data signals received at (13) is compared, at different relative phases, with a series of coded reference signals using an arrangement of s...

Process for the prepration of thioethers by reacting a silylated thiol of the general formula: R - S - SiR1R2R3 I wherein R represents an organic group and R1, R2 and R3 are the same or different and each represents an alkyl group having 1 to 4 carbon atoms, with an organic halide, sulphate or sulphonate in the presence of hexamethylphosphoric triamide as a solvent or co-solvent. The process is c...

The appts. is used for arranging reverse lengths of single or multiple fibre optic conductors and includes two spaced walls each with partitions spaced along the outer surface to permit light frictional retention of individual fibres between pairs of partitions. There are further partitions along the inner surface of one wall. - An unjacketed length of a cable with at least 5 times the organizer b...

A pair of flexible clear plastic sheets or plastic layers 33, 35 laminate opposite sides of the paper card 23 containing the microfilm 31. A lens hole 61 is formed through the clear plastic layers 33, 35 and through the paper card 23 at an end part opposite to the microfilm 31. A round p...

The method is for theft prevention of valuables during transport. The items are placed in a storage box (12) with smooth exterior and a wt. which is much heavier than can lifted by a man. - The walls of the storage box comprise several layers (18,18',19',20'). of which at least some are of steel. Over the greater part of the layer surfaces facing each other they are devoid of mutual connection.(2)

The building wall section separates inner and outer air. The bearing body comprises two or more separate parts (15,16) but joined by a heat insulating union (17,18). The parts have longitudinal, wholly enclosed channels (19) accommodating screws or bolts (22) at their ends.(2)

A roadway featuring a tread (7), one or more load-bearing or load-dispersing units as well as thermal insulation to protect against frost damage, whereby the load-bearing unit is comprised of ground-situated, open-bottom covering (1) that extends along the longitudinal direction of road and is filled with thermal insulation (6). The thermal insulation (6) comprises a fluid, which after filling har...

The sludge is pumped from the sludge well to a container via a return pipe. In the container it passes through a filter under gravity and back to the well. The solid material remains on the filter and when the well is emptied, can be removed and handled as a dry product. The filter container and its cover can be made of a cement material, steel plate or wood in a circular or rectangular shape and ...
