Abstract: A heat-insulating body such as a heat-insulating slab is made whose insulating and heat-absorbing material includes a fine powder, in particular a silica aerogel which is pressed to form the body. To carry out the pressing operation a sack-like sheath is required but between the sheath and the insulating material a separating agent is provided which results in the fact that the surface of the insulating material does not intimately engage with the sheath which is for example of glass fibre fabric, the sheath being movable with respect to the insulating material after the pressing operation. Apart from the fact that the sheath can be removed for any cases where it would be a cause of disturbance, additionally the insulating body provides improved bending properties and even when made with a high pressing rate has a homogeneous structure. To make the insulating body the separating agent may be applied to the inner surfaces of the sheath, the particulate insulating material then being introduced and the sheath sealed, whereafter pressure is applied.

Title: Monolithic integrated circuit mfr. - by partial etching and refilling of conductor zones through mask
Inventor: EGELHAAF PETER DIPL PHYS DR
IPC: H01L21/20
Filed: 1980-03-03
Abstract: A monolithic integrated circuit is produced by applying to the surface of a semiconductor substrate of a certain type through a mask either the same or the opposite type of conductor zones. These zones are partly etched away on the surface and then filled up to the same level selectively with a different semiconductor. The final layer is an overall layer of a high resistance epitaxial deposit. After the conductor zones(2) have been produced by diffusion through a mask(3) of silicon oxide or silicon nitride on the semiconductor substrate(1) of (100)-oriented silicon, grooves of 0.3-3 microns are etched and selectively refilled by an epitaxial layer(4). After the mask(3) has been etched away, a high- resistance epitaxial layer is deposited all over. The selective refilling is done in a gas mixt. of SiH4 (0.05-0.3%), HCl (0.3- 2%) and H2 at a temp. of 1050-1150 deg.C. The partial etching in a mixt. of HCl and H2 takes place at the same temp. This simplifies the removal of the mask because it does not carry any polycrystalline deposit.

Title: Thin film chromatograph - uses plate with sorption layer and fluid applied directly from annular dosing container
Inventor: BUNCAK PAUL DIPL ING
IPC: G01N30/91
Filed: 1980-09-19
Abstract: An arrangement for performing a thin layer chromatographic analysis with a plate or foil carrying a sorption layer involves mounting the sample to be analysed at a defined distance from a dosing surface and decomposing it into its constituents by introducing a fluid. It provides more modes of operation than conventional methods. This is achieved economically in terms of equipment and fluid consumption and using a conventional DC plate (2). The fluid is fed directly onto the sorption layer to surface gaps (11) without using capillary action. Using an annular dosing container (1) with samples either side of an annular outlet circular and anticircular thin film chromatographic analyses can be performed simultaneously. The surface gap (11) is varied by the mechanical pressure of the container on the plate or foil.

Title: Method and circuit arrangement for transmitting data signals using the time division multiplexing method
Inventor: BADER EDGAR DIPL ING
IPC: H04J3/06
Filed: 1981-08-14
Abstract: Time division multiplexers for transmitting data signals may comprise a plurality of channel groups which in turn are again homogeneously subdivided into k = 2<m> (m = 0, 1, 2,..., Id n) channels. n is the highest possible number of channels in one channel group. The channels of a channel group are envelope-interleaved and have the same envelope structure with a permanently allocated sync bit. The sync bit sequence of a channel is alternately "0" and "1". The consecutive sync bits in one channel group are monitored at the receiving end to identify the channel group subdivision. If ax is a sync bit occurring at any given time in one channel group, the associated modulo-2 sums ax (+) a(x + 2m) and/or ax (+) a(x - 2m) are formed for m = 0, 1, 2,..., Id n of each channel group.
