Abstract: ABSTRACT          A seal between an ingot mould and a base plate or between a head-box and an ingot mould is formed from a pack of flat, flexible strips, for example, of cardboard or aluminium interlinked at spaced intervals along the strips.  The joints between any one strip and an adjacent strip next to one face thereof are staggered in relation to the joints between the one strip and the adjacent strip next to the other face thereof.  The pack is expanded lengthwise to separate the strips where they are unjoined and form generally hexagon shaped cells and is then placed on the base plate with the longitudinal edges of the strips of the pack on the base plate.  The expanded pack is arranged lengthwise into a closed figure corresponding to the shape of the ingot mould.  The ingot mould is then placed on top of the expanded pack which is crushed between the ingot mould and the base plate to form the required seal. A head-box seal is similarly made between the top face of the ingot mould and the head-box.

Abstract: A B S T R A C T The invention relates to so-called turbo hydrodynamic reversing drives which incorporate a hydrodynamic torque converter for each of the two rotary drive directions.  The switching in and out of each torque converter is effected respectively by filling the latter with working fluid or by draining it by means of a filling pump, a circuit which includes filling and draining lines, and a two-way reversing valve for connecting the filling line of one or other converter to the filling pump and closing off its respective draining line.  Such drives are used for vehicles which frequently change their travel direction i.e. shunting locomotives and earth-moving vehicles.  While the reversing valve is being changed over from one operating position to the other, the filling lines of the two torque converters are connected to the filling pump, and the draining lines of the two torque converters are also at least partly open.  Such an arrangement enables a change of travel direction to be effected as quickly as possible.

Abstract: The disclosure describes a method for the preparation of implants from ceramic substances, especially with a porous surface stimulating the ingrowth of bone tissues, by introducing a model of the implant into a high-temperature embedding substance which has been mixed to a paste and leaving it in this until the embedding substance hardens and a negative mold of the implant is produced. After removal of the model the mold is lined via an opening reaching into its interior with a layer of a ceramic substance which should form the outer layer of the implant. The cavity of the mold is subsequently filled completely with dentine or core substances, the opening is then sealed with a high-temp-erature embedding substance, mixed to a paste, the embedding substance is allowed to dry and the whole thing is then heated to the sintering temperature of the ceramic substances used and the ceramic substances fired at this temperature for the usual time. The disclosure also describes an implant of ceramic substances and having a porous outer layer. The porous outer layer consists of a ceramic substance according to the DE-OS 2711 219 with an addition of substances stimulating bone formation and/or bone growth in a quantity of 5 - 70 wt. % relative to the dry content of the ceramic substances, especially tri-calcium phosphate and tertiary calcium phosphate.

Abstract: ABSTRACT OF THE DISCLOSURE    The invention provides a system for purifying tallow. Tallow received from rendering plants typically is contaminated with suspended plastic polymer fines.  According to this invention plastic polymer fines are removed from tallow containing such fines by adjusting the temperature of the tallow to just above its freezing point, and contacting the tallow in a selected organic solvent to form a solution comprising the solvent containing dissolved tallow, and particles of undissolved plastic polymer.  The resulting solution is then filtered to remove the particles of undissolved plastic polymer, and the filtrate which results is treated to separate the tallow from the solvent, e.g. as by evaporating the solvent under reduced pressure.  The separated solvent may be condensed and recycled to treat fresh tallow.

Abstract: "HOLD-DOWN DEVICE FOR DOCKLEVELLER"    ABSTRACT OF THE DISCLOSURE             A releasable hold-down device is provided for use in a dockleveller wherein dock-raising springs are used to raise the dockboard. The hold-down device comprises a hydraulic cylinder assembly having the piston connected to the dockboard and the cylinder connected to the dock-leveller frame.  The cylinder assembly must thus expand and contract to permit the dockboard to be raised by the spring and lowered by the weight of a man standing on the dockboard.  The cylinder assembly has fluid-filled stem and base chambers.  A connecting conduit permits fluid movement between the chambers.  A valve means in the conduit controls this fluid movement.  There is provided means for mechanically opening the valve means to permit the dockboard to be raised by the spring with concomitant expansion of the cylinder assembly.  When such mechanical opening means is inoperative, the valve means is operative to (1) close if there is a greater fluid pressure in the stem chamber than in the base chamber (thus locking the device and preventing the spring from raising the dock-board), and (2) open if there is a greater fluid pressure in the base chamber than in the stem chamber (thus permitting the cylinder assembly to contract when a weight acts on the raised dockboard).

The gaseous product stream from a chlorine dioxide generator is scrubbed with an aqueous salt mixture containing an approximately stoichiometric quantity of sodium hydroxide, which reacts prefer-entially with the chlorine, yielding chlorine dioxide of high purity.  The absorption system is operated under such conditions that the chlorine is converted to sodium chlorate and sodium chloride, which may then be recirculated to the chlorine dioxide generating system.  The scrubbing salt solution is adjusted so as to produce an R-2 mixture upon reaction with the chlorine in the chlorine/chlorine dioxide stream.

Abstract: ABSTRACT     METHOD FOR THE PRODUCTION OF PRECISION SHAPES     A method for producing precision shapes which includes the consolidation of powder metal preforms into a shaped por-ous preform.  When formed by powder metallurgy techniques, pre-cision shapes have highly desirable characteristics from the standpoint of grain structure, and the production of preforms in accordance with the invention enhances the achievement of such shapes.  In practicing the method, a first coating 16 is applied to the preform 14, this first coating being porous while providing a diffusion barrier.  A second coating 18 which is also initially porous is then applied and the coated preform can then be degasified by subjecting the preform to a vacuum, particularly at elevated temperatures.  The coated pre-form is then heated under vacuum to a temperature such that the second coating is densified to the extent that it becomes non-porous.  Finally, the preform is subjected to a hot isostatic pressing operation whereby formation of a high integrity, ful-ly dense metal shape results.
