Patent DE-3939178-A1 (DE)
Inventor: BAUCKHAGE KLAUS PROF DR ING
IPC: B05B17/06
Filed: 1989-11-27
Abstract: In a device for atomising at least one jet of a liquid or solid material, preferably molten metal, the atomising process takes place in a stationary ultrasonic field which is produced between at least one pair of ultrasonic vibrators. In order to increase performance, a plurality of atomising fluid jets, and in a complementary fashion thereto additional fluid jets (e.g. gas) are introduced from nozzles in each node point area of the stationary ultrasonic wave. In this way, the atomisation fluid mass throughput is very greatly increased and thus the atomisation power raised. In addition, special sonotrode shapes are proposed in order to increase the performance further. <IMAGE>

Title: Plastic stopper for e.g. wine bottles - consist of e.g. foam body in two halves joined together by horizontal gas barrier of e.g. foil coated each side with polyethylene
Inventor: PFEFFERKORN BERND
IPC: B29C44/06
Filed: 1989-12-07
Abstract: A stopper for bottles, and partic. for wine or champagne bottles, has a plastic stem with gas-tight barrier layer. This stem is solid; the barrier layer runs at right angles to its axis and divides the stem into upper and lower halves. The barrier can be made of polyester-coated aluminium and the body sprayed-on foam. Specifically, an exploded view of a stopper for wine bottles shows that it consists of an upper (2) and a lower (3) part with the barrier layer (4) between. The top and bottom (2,3) are made of e.g. ethylene-vinyl acetate and the barrier (4) is alumnium with a thin layer of polyethylene on each side (5,6). The polyethylene films (5,6) are bonded on hot. The structure indicated is pressed together into one place. In this the two parts (2,3) stay bonded together even if subjected to torsinal forces. A champagne type of stopper (or for e.g. sherry) has a similar construction with a bevelled bottom edge and a wiper top head. ADVANTAGE - The prod. provides an effective gas barrier in a solid plastic cylindrical plug.

Prodn. of the photodetector involves (i) producing a smooth transparent electrode layer (thin conductive oxide layer) on a transparent substrate; (ii) depositing an amorphous photoconductive active layer by glow discharge; (iii) producing a back face metal electrode on the active layer by vapour or sputter deposition; (iv) depositing an undoped amorphous semiconductor layer on the opposite surface of the substrate from the thin conductive oxide layer; and (v) producing an arrangement for conducting away and amplifying current generated in the active layer. USE/ADVANTAGE - The photodetector is used esp. in optical measuring processes employing coherent, esp. laser light.  It is unaffected by room lighting or daylight, has a narrow band of 500-1000 nm, and is simple and inexpensive to mfr.

Patent DE-4015857-A1 (DE)
Inventor: LIESENFELD BRITTA
IPC: C01B33/26
Filed: 1990-05-17
Abstract: The description relates to a simplified process for making expandable stratified silicates of the smectite type by the hydrothermal pressure treatment of mixtures and/or co-precipitates of the stratified silicate forming components in the presence of excess water and free bases. The novel process is distinguished in that a reaction mixture is placed in the hydrothermal reaction stage, the excess bases of which are made up at least partly of volatile organic amine compounds, the mineral solid phase formed is freed of the aqueous-basic part of the reaction mixture and, if necessary, residual parts of the organic amine compounds are evaporated out of the solid phase. The organic amine compounds are preferably primary, secondary and/or especially tertiary amines with a limited carbon content. It is also preferable to operate with at least preponderantly oxidic and/or hydroxidic reactants so that the reaction mixture is substantially free of non-volatile foreign components.

Patent DE-4112222-A1 (DE)
Inventor: EMRICH HELMUT
IPC: B65H7/08
Filed: 1991-04-15
Abstract: The invention relates to a device for controlling the sheet run in the region of lay marks in sheet offset printing machines. To ensure that the sheet at the lay marks has as much stabilisation time as possible for self-alignment, it is proposed according to the invention to select the sampling point for sheet scanning at the lay marks in dependence on the condition of the machine (pressure on, pressure off). In both the pressure-on position and the pressure-off position, the sampling point (angular value of a constant speed shaft) is set sufficiently late for the elements which release or lock the sheet run and switch the printing mechanism cylinders on and off to be still actuable. Switching between these sampling points occurs automatically.
