Title: Large-surface insulating vacuum panes - have sidewalls sealed from atmosphere, with min bridging
IPC: E06B3/66
Filed: 1975-04-03
Abstract: The building components, from which air can be evacuated, have a reflecting layer for heat insulation, esp. for residential buildings and other large entities. They may be used for window glazing, esp. glazing with optically selective layering.

Title: Detection of bearing frictional moment - uses bearing, driven on inner race, held in normal position
Inventor: STEPHAN HUBERTUS DIPL ING
IPC: G01M13/04
Filed: 1975-06-12
Abstract: The friction moment determination is used especially for ball bearings rotating slowly or only intermittently. The position control system consists of a photoelectric differential position indicator, a variable gain amplifier and a rotary magnet system. The control system holds the outer race without contact and free of shearing force in a normal position by generating an electrical signal via the differential position indicator as a result of any twisting of the outer race out of the normal position. This signal is amplified and converted into a restoring moment, whereby the outer race is turned back to its normal position.

Title: Flash cube adaptor for self developing camera - has fitting for multiple flash cubes ignited piezoelectrically or by impact detonator
Inventor: ETTISCHER HELMUT
IPC: G03B15/04
Filed: 1975-08-26
Abstract: The adaptor for an instant developing camera enables both kinds of flash cube operating without battery ignition to be used.

Title: Advertisement column foil sheathing - has quick-action closure and consists of fabric reinforced plastics or plasticised textiles
Inventor: SCHIEFEN HANS
IPC: G09F15/00
Filed: 1976-09-13
Abstract: The sheathing for the advertising column has a closure in the manner of a sliding fastener or a stud fastener. The sheathing can consist of two or more circular sections arranged above one another. This type of fastening ensures that old advertisements stuck onto the column can be removed quickly and clearly. Hitherto, it has been difficult to detach them from the column because they adhere firmly to the column to make them durable against wetness and weather conditions. Brushes, spatulas and even blow-lamps are no longer needed.

Excessive freezing point lowering is based on stabilisation of hydrate formation in soln. Freezing curves, obtd. by plotting freezing point lowering against wt. % solids in aq. soln., shows that a given freezing point lowering could be achieved by using only 1/4 of new antifreeze, ("X"), compared with quantity required on using ethylene glycol.

Title: Roasting lime in double shaft furnace - where shafts are used alternately for regenerating heating of air used to burn fuel
Inventor: DEUSSNER HERBERT DIPL ING DR
IPC: C04B2/12
Filed: 1976-12-17
Abstract: Burnt lime is prepd. by a regenerative co-current calcining process using >=2 shaft furnaces operated alternately so the exhaust gases from a heated shaft (a) provide regenerative heat in the other shaft (b). The air required for combustion in shaft (a) first flows through the completely burnt lime in both shafts (a,b) for preheating, and is then removed from the shafts (a,b) and is fed through the hot unburnt lime in shaft (a) so it is heated to the de-acidification temp. Pref. each shaft has a preheating zone (I); a regeneration zone (II); a roasting zone (III); a post de-acidification zone (IV); and a cooling zone (V). An adjustable air compressor is fitted in the duct connecting zones (V,II); and an exhaust gas blower extracts gas out of the top of the shafts. Compared with conventional regenerative co-current processes, method provides a simpler plant design with optimum utilisation of energy.

Title: Mine gallery concrete lining advance system - has intermediate container fed by pneumatic conveyor, supplying wet mixer, and concrete pump
Inventor: GOETZE WILHELM DR ING
IPC: E21F15/08
Filed: 1976-12-22
Abstract: The cement conveying in mining operations, for eg for lining the walls of galleries, includes conveying the dry material through a pneumatic conveyor (9) from a remote point, then collecting it in a storage bunker (5) at a suitably sited position from the point of application of the cement. A feed screw (50) through this bunker then discharges into an intermediate container (6) with double screws, acting as a mixer, and into which water is discharged from a line (61) controlled by a valve (60). The wet concrete can then be discharged by a concrete pump (8) through a line (80) to the actual working position. This method avoids dust formation.

Title: Prodn. of iodine-123 for nuclear medicine - by irradiation of cooled tellurium di:oxide target and subsequent thermally induced release
Inventor: SCHULZ FRIEDHELM
IPC: G21K5/08
Filed: 1977-02-21
Abstract: Prodn. of isotope iodine 123 by nuclear reactions in a tellurium target is described. The target used is of tellurium dioxide, it is directly surface cooled during its nuclear irradiation, and afterwards is heated to up to, or even about 750 degrees C, to release the iodine 123. Used esp. for prodn. of iodine-123 for nuclear medicine. By using tellurium dioxide, which is a glass, a much higher level of irradiation is possible than with a simple tellurium target. Thus a much more concentrated process can be achieved resulting in a greater prodn. of iodine 123. The cooling water is direct contact with the target surface provides a necessary direct cooling and oxidation of the target material is prevented. In addn., the tellurium dioxide target is not damaged by the final heat treatment and can be used repeatedly.

Title: Vessel for storing separate substances - has plastic container with sealed off chambers and seal plug to remove separation wall for mixing
Inventor: CHEETHAM JEFFERY JAMES
IPC: A61C5/66
Filed: 1977-03-07
Abstract: The vessel (10) which is used to store two separate substances, has a division wall (19) that produces two chambers (11, 12) inside the vessel. When the first chamber (12) is filled, the vessel part (13) and mating sleeve (14) are assembled so that the substances is sealed off inside. The second chamber (11) is then filled and sealed with a piston like stop plug (15). When it is required to mix the two substances inside the vessel, the stop plug (15) is pushed as far into the vessel as it will go. This causes the separation wall (19) to be partially sheared off by the leading edge of the stop plug (25), thus the two contents of the vessel are able to mix. The vessel is esp. for mixture of dental amalgam.
