Title: Granulating glass mixes contg. toxic dusts - by addn. of materials requiring water of crystallisation
IPC: C03C1/02
Filed: 1978-03-28
Abstract: Method of preparing raw materials for the glass industry in which toxic dusts can be added to glass units, and/or glass melt aggregates by binder addition and granulation comprises mixing the toxic materials with materials requiring water of crystallisation. The mixt. is then mixed opt. with addition of the main portion SiO2, and other usual glass raw materials, together with sufficient water for granulation. Specifically practically all the added water is added as water of crystallisation leaving a moisture content in the prepared granulate of 1-4 (2-3) wt%. The toxic materials can be introduced into the granulate form without the need for drying the product since the water is taken up by the materials requiring water of crystallisation.

Title: Wet development appts. for copier - uses drive rollers in bath developer and suspended electrodes with corrugated profile fastened to bath lid
Inventor: TAKASUGI NOBORU
IPC: G03G15/10
Filed: 1978-05-19
Abstract: Appts. provides wet development of the latent image in an electrostatic copier. The developer is contained in a tray (3) through which the copy is passed by means of drive rollers (1, 2, 7, 8, 9, 10, 14, 15) and guide plates (11, 12, 13). Fixed electrodes (4, 5, 6) with a corrugated profile are mounted on the inside of the developer tray's lid (19) so that they can be removed when the lid is removed. When in the developer, the electrodes form the upper profile corresponding to the lower guide plate shape so that they are a constant distance from the copy. The corrugated profile of the electrodes is to prevent the copy sticking to them during passage through the developer.

Title: Preventing water inflow to fuel element during reactor vault flooding - by fission gas pressure rise esp. produced by automatically closing valves
Inventor: GOETZMANN CLAUS DIPL ING
IPC: G21C9/00
Filed: 1978-09-14
Abstract: An inflow of water into fuel elements inside a flooded reactor vault esp. for gas-cooled, fast reactors where fission gas can be removed from the fuel elements through intended leakage points at the junction between the fuel element casing and the core support structure is prevented. While the reactor vault is flooded, the fission gas removal system is subjected to a gas pressure higher than the water pressure at the intended leakage point. Specifically, the parts of the fission gas removal system that are located inside individual fuel elements are each shut off on the upstream side of the intended leakage point be means of a valve system operated as a function of the pressure and temp. on the two sides of this point. Used esp. for a gas-cooled fast reactor where fission prods. are led off from the fuel elements to an extn. system. The arrangement enables the reactor vault to be flooded without water entering fuel elements.

Patent DE-2937313-A1 (DE)
Inventor: SIGG HANS
IPC: B24B49/04
Filed: 1979-09-14
Abstract: The invention permits, for measurement-controlled longitudinal grinding on a cylindrical grinding machine, the number of steps, and thus the machining time, to be reduced. This is achieved in that the measurement head of the measurement control means scans the workpiece at the point where, on feeding the grinding wheel, machining takes place, and in that the feed step is broken off on reaching the diameter at which one phase (e.g. rough grinding) is switched over to the next phase (e.g. finish grinding). <IMAGE>

Title: High speed recording equipment drop generator - has heating element producing bubbles near end of fine tube
Inventor: SHIRATO YOSHIAKI
IPC: B41J2/05
Filed: 1980-04-02
Abstract: A drop generator uses a bubble (1B) source (4) in a fine tube (1) carrying the fluid (IK). The bubbles are produced and dissipated so as to cause drops of fluid to be forced out of an opening in the fine tube. It is more compact than conventional drop generators but is suitable for high speed recording and high density nozzle arrays. The bubbles cause a high pressure to develop which in turn causes the agitation of drops (7) of practically constant dia. The bubble generator is positioned so that the bubbles are not in contact with the surrounding air. It is a flat heating element lying along the fine tubes. The distance of the edge of the element from the tube outlet is between one and fifty times the opening dia.

Title: Returning material falling through calender rollers - in which part of conveyor belt beneath rollers feeds back to rollers
Inventor: COLLIN HEINRICH DR ING
IPC: B29B7/56
Filed: 1980-04-08
Abstract: Material which drops through calendar rollers is automatically fed back to them by a device which draws off the finished calendered sheet or film. A conveyor belt is mounted on the ends of a parallelogram frame and pivots about the ends of fixed shafts from a horizontal state to return and take-off positions, this belt moves about a lateral axis when pivoting to the return feed position and the belt itself passes round the first roller through 90 degrees to catch material falling through and return it to the rollers when the belt pivots into its take-off position the material is picked up from the belt and drawn off the front roller. Automatic operation provides consistent quality and eliminates dependence upon or hazard to operators, suitable for e.g. laboratory use or working with dangerous/explosive/aggresive materials.
