Title: Valve gear for two-stroke engine exhaust - has spherical rotary slide valve with offset tangential groove and loose ring seal
Inventor: RAU HERBERT
IPC: F01L7/10
Filed: 1977-03-28
Abstract: The IC engine valve gear, esp. for 2-stroke engine exhausts has an internally cooled spherical rotary slide valve (20) rotating about an axis (22) perpendicular to the cylinder axis (11) in bearings in the exhaust duct wall. Gas flow past the valve is via a tangential rectangular section groove (25), perpendicular to the axis of rotations. Its plane of symmetry (30) through the valve centre is inclined to the cylinder axis. Leakage is prevented by a sealing ring (26) with its axis in the groove plane of symmetry and internal dia. equal to the groove width. The ring is of U-section, with a rounded face against the valve and flat face against a ledge in the cylinder exhaust port (18).

Title: Publicity or decorative display device - creating illusion of shapes moving across projected image, uses patterned projecting roller and flat glass or plastics screen
Inventor: BOELCH ALFONS
IPC: G09F13/36
Filed: 1977-04-28
Abstract: Illusion of natural movements in decorative and/or publicity displays is achieved using an image-projecting roller which is slowly rotated by an electric motor; the roller being installed behind the publicity picture or advertisement being projected. The roller carries patterns or figures obtd. by e.g. cutting out or etching away parts of metal foil previously applied to it, and as the roller revolves slowly, the images of the remaining metal areas are projected, together with the (static) picture of advertisement onto a flat or reliefed surface, thus creating the illusion of shapes moving across the picture. The device used incorporates 1 or 2 glass or plastics e.g. PMMA, plates.

Title: Heat insulating element - with metal wire braiding on hot surface side of mineral fibre packing
Inventor: MUELLER KLAUS-D
IPC: B65D90/06
Filed: 1978-03-23
Abstract: Insulating elements for use at high temp. e.g. on board ship, consist of a core of insulating material, such as mineral fibre, which is enclosed in a tissue. On the cold, outer surface this tissue can consist of a glass fibre fabric dipped in a textile size. Against the hot surfaces, the tissue is a metal wire braiding or a glass fibre braiding with a metal wire core.

H2SO4; or is cracked by heating to obtain MgO recycled to the MBS stage and SO2 fed into the purified bisulphite soln. The MS is pref. cracked at 500-900 degrees C., possibly using some heat from the lye boiler. The MS is pref. dried before craking, which pref. occurs in a stream of SO2, and the resulting SO2 is pref. liquefied. Used in the prodn. of cellulose, using a completely closed circuit for the chemicals, and to produce a digestion acid contg. any desired amt. of SO2 in soln.

Title: Leaf filter with solvent removal by evaporation - having heat for evaporation provided by hot wash liquor used at end of filtration followed by evaluation
Inventor: BENDER WOLFGANG
IPC: B01D37/00
Filed: 1978-12-16
Abstract: The liq. phase of a very finely divided solids suspension is removed in a leaf filter. When a sufficient cake has accumulated on the leaves, the cake is washed with hot solvent. This is then drained back to a heated storage vessel using hot N2. The filter vessel is then evacuated using a vacuum pump with a condenser in the line. The residual solvent on the cake evaporates, cooling the filter in the process. Used for recovering solids with a very fine particle size from suspensions liq. after liq. phase reactions. This allows a satisfactory drying out of the solids after a mechanical liq. removal stage.
