Title: Metallurgical vessel blower system - has fireproof perforated brick with charged gas passages contg. fireproof gas washing brick
IPC: B22D1/00
Filed: 1991-02-08
Abstract: The perforated fireproof brick covering the fireproof gas washing brick in the blower system for a metallurgical vessel, has passages charged with gas. Pref. the passages in the perforated brick and the passages of the gas washing brick are separately charged with gas. The gas passages in the perforated brick are charged with gas from a second chamber through a further gas feed. The gas passages are connected to the central gas line through a three-way valve. The gas passages in the perforated brick from coaxial channels round the gas washing brick. The perforated brick is pot shaped, with a frame round the outside and at the lower side, covering the lower side with a base plate to form a second chamber connected to the gas passages in the perforated brick. The perforated brick has an inner frame to hold the gas washing brick. The gas washing brick is covered by a closing sleeve with gas passages, with an exterior plate mantle covering, and a lower ring chamber, covered by a base plate, which is connected to the gas passages in the covering sleeve. The ring chamber is charged with gas from a gas feed. The perforated and gas washing bricks are monolithic. ADVANTAGE - The structure forms a blower system with a long life, with a trouble-free operation without forming plugs and developing stoppages which would have to be cleared.

Title: Mfg. transmission electron microscope sample prepn. - mechanically removing material followed by sputtering in scanning ion microscope to form recesses
Inventor: DRIESEL WOLFGANG
IPC: G01N1/06
Filed: 1991-04-16
Abstract: The preparing method involves using a raster ion microscope and mechanical removal of material on both sides of the region (2) to be investigated at an angle between 10 and 60 deg. to the surface.

Patent DE-4141645-A1 (DE)
Inventor: DOEBLER WALTER
IPC: B29C49/24
Filed: 1991-12-17
Abstract: A process and device for producing plastic containers, e.g. by injection or blow moulding, in which the process for making the plastic containers features an envelope sheet (8) in the form of a label integrated into said containers by the in-mould labelling process. To this end, a moulding tool has a mould and can be closed or opened, and molten plastic may be introduced therein via an aperture. An envelope sheet (8) is introduced into the mould (2) before the injection mould is closed by conveying it between two conveyor belts (21, 22) against a stop edge (15) of a suction holding mandrel (4) where the leading edge of the envelope sheet is pulled in via first depression apertures (16) and the suction holding mandrel (4) is then rotated, thus winding the envelope sheet (8) upon it. Via second depression apertures (19) distributed about the periphery, the envelope sheet (8) is held in the wound condition by the suction holding mandrel (4) over its entire length. When the moulding tool then opens, the suction holding mandrel (4) is swung into an intermediate space thus formed and transferred to the mould (2).

Inventor: BORGER WALDEMAR DR
IPC: H01M4/62
Filed: 1992-07-22
Abstract: An expander, which has a favourable effect on both the cold-start capacity and on the charge acceptance of negative lead electrodes, comprises only those organic components of a commercial expander material formed mostly of materials contained in wood such as lignin, among others, which can be precipitated from a solution or dispersion of the original product by means of metal ions such as Pb<2+>, Ba<2+>, Mg<2+>, Al<3+>, Ca<2+>, Sr<2+>.
