Title: Method of driving a glass tempering system and glass tempering system for carrying out the method
Inventor: REUNAMAKI PAULI TAPANI
IPC: C03B27/04
Filed: 1985-08-29
Granted: 1988-06-09
Abstract: The invention relates to a method of driving a glass tempering system and to a glass tempering system for carrying out the method. The main components of said system are a loading section (1), a heating furnace (2), a quench and cooling section (3) and an unloading section (4). The sections are provided with conveyors, which are made of horizontal rollers and can be driven in unison or separately. The furnace and quench and cooling section conveyors (12, 13) are provided with a common drive mechanism (5, 6, 7, 8) for driving said conveyors (12, 13) either at the same rate of speed or for uncoupling said conveyors from each other for stopping the quench and cooling section conveyor (13). Instead of stopping it, the quench and cooling section conveyor (13) can be coupled to effect a very slow movement after the quenching is finished and a glass sheet load is being cooled to a handling temperature. By means of stopping or setting it in very slow motion, it is possible to produce stresses in quenched glass which do not normally damage glass but which shatter those glasses that would later break due to the faults already there. Neither will the stationary or very slowly moving rollers be damaged when glasses shatter. During the quenching, the furnace (12) oscillates empty with a result that the furnace overload caused by even the thickest glass sheets will have time to compensate prior to passing fresh glass into the furnace.

Title: Method for producing high-carbon steel wire rod
Inventor: BACH NORBERT
IPC: C21D9/52
Filed: 1985-07-18
Granted: 1988-07-21
Abstract: In the production of medium carbon steel wire rod, upon leaving the hot rolling mill, the rod is cooled in two phases. The first phase is operative as the rod moves at end-of-rolling speed along a cooling line disposed between the finishing block and feed rollers disposed at the entry of a head for placing the rod in overlapping turns on a conveyor, the cooling line being continuous-i.e. being devoid of air cooling breaks between consecutive intensive cooling sections, the length and capacity of the cooling line being such that the surface temperature of the rod at the end of the first phase is between, on the one hand, the start-of-martensitic-transformation temperature for the particular steel concerned and, on the other hand, the latter temperature plus 200 DEG  C. The second cooling phase is operative upon the rod once it has been placed in overlapping non-concentric turns on the conveyor, the time which elapses between the end of the first phase and the start of the second phase being less than the time needed for the percentage of transformed austenite to exceed 5%. Austenite transformation is at least 95% at the departure from the second phase.

Abstract: A voltage lower than that appearing during use is applied between two conducting parts of the machine separated by the insulation to be tested. The charging current through this insulator is measured at predetermined instants after the time at which the voltage is applied. Values of the charging current to be measured are tapped by means of a sampling circuit at a certain number of predetermined instants after the time of application of the voltage. The sampled values are transformed into digital form so that they can be memorized in a computing unit. From the measured and sampled values of the varying charging current, three time constants are calculated by using as an interpolation formula the relationship: Jc(t) = I1exp(-t/ tau 1) + I2exp(-t/ tau 2) + I3exp(-t/ tau 3), where Jc(t) is the measured charging current, t is the time at which a measurement is made, I1, I2, I3 are parameters to be calculated and tau 1,  tau 2,  tau 3 are the time constants to be calculated and displayed. <IMAGE>

Abstract: A method of closing a metal container, esp. radioactive material inside an inner container, consists of fitting a closure lid and welding it to the body of the container. The inner face (13) of the lid is a concave dome and the lid is applied under an axial compressive force, greatly exceeding the weight of the lid, onto the bearing face (10) of the container; this pressure is maintained during the entire welding operation and then released. The pressure may be applied by an external, separate compressing device or by a threaded lid itself (as shown), or by a lid which is fitted as a shrunk fit into the mouth of the container, the load of the pressing device being afterwards removed. A radioactive waste container with lid fitted on by welding has the lid internally concave (domed) (13), and pref. externally convex (14). The lid bears against a bearing face (10) around the end opening of the container by its own bottom face (5).

Abstract: Dehydrated liposomes are prepared by drying liposome preparations under reduced pressure in the presence of one or more protective sugars, e.g., the disaccharides trehalose and sucrose. Preferably, the protective sugars are present at both the inside and outside surfaces of the liposome membranes. Freezing of the liposome preparation prior to dehydration is optional. Alternatively, the protective sugar can be omitted if : (1) the liposomes are of the type which have multiple lipid layers ; (2) the dehydration is done without prior freezing ; (3) the dehydration is performed to an end point which results in sufficient water being left in the preparation (e.g., at least 12 moles water/mole liped) so that the integrity of a substantial portion of the multiple lipid layers is retained upon rehydration. Concentration gradients capable of generating transmembrane potentials can be created across the liposome membranes either before or after dehydration, and the transmembrane potentials resulting from these gradients can be used to load charged materials, e.g., drugs, into the liposomes.
