Title: Device for protecting the ends of drill pipes and borehole linings
Inventor: JAEGER ARNOLD
IPC: B65D59/06
Filed: 1982-06-21
Abstract: Devices of this type have a thread-like profiled portion so that the device can be screwed onto the ends of drill pipes or borehole linings. Here, at least the profiled portion is made of steel. In these devices, slackening - e.g. caused by vibrations during transport - is to be avoided by the device being given elastic, plastic or elastic-plastic self-locking elements which prevent the undesirable slackening. These elements project into the base of the profiled portion and are deformed during screwing, which results in a restoring force bringing about the fixing.

Title: Measurement transmitter for a spirometer
IPC: A61B5/093
Filed: 1983-02-18
Abstract: The measurement transmitter for a spirometer for the determination of lung volumes and lung time volumes has two tightly sealed measuring chambers (20, 30) of variable volume which can be connected to a mouthpiece in each case via their own line connection (21, 31). The first measuring chamber (20) is intended for inspiration measurement and the second measuring chamber (30) is intended for expiration measurement. A wall (5) whose position is variable is allocated to the two measuring chambers (20) which undergo proportionate changes in volume when the position of the wall (5) changes. At identical volumes of the measuring chambers the measurement transmitter can therefore be used as a transducer for the generation of an expiration gas flow by means of inspiration. <IMAGE>

Title: Power-assisted steering
Inventor: BARTHOLOMAEUS REINER
IPC: B62D5/06
Filed: 1983-03-22
Abstract: A power-assisted steering system has two steering column halves which are connected to one another via a torsional spring and by which two rotation meters are actuated, of which one measures the rotational angle differential between the two steering column halves which is a measure of the steering force exerted and the other rotation meter measures the angle of rotation which is a measure of the steering angle and thus of the position of the piston in the working cylinder of the steering gear. The angle of rotation is processed as a feedback variable together with the rotational angle differential signal and a signal which is dependent on the vehicle speed in a circuit to form a control signal which is fed to a proportional valve which is a component of the bearing control circuit. As a result, the steering behaviour is improved. The rotation meters are designed in such a way that the measuring housings provided with the electrical lines are arranged fixed to the housing. <IMAGE>

Title: Process for preparing corundum by smelting bauxite in an electric arc furnace with simultaneous aluminothermic reduction of the accompanying oxides of the bauxite
Inventor: SROKA RICHARD DIPL CHEM
IPC: C01F7/38
Filed: 1984-03-12
Abstract: Synthetic corundum is prepared by reductive smelting of calcined bauxite in an electric arc furnace. In this process, the accompanying oxides of the bauxite (Fe2O3, SiO2, TiO2, etc.) are reduced partially or wholly by carbon to give the metal, which settles at the bottom of the melt. Above this,  alpha -Al2O3 crystallises as corundum with an Al2O3 content of approximately 95-96% (standard corundum). If a higher aluminium oxide content such as, for example, in semiprecious corundum or precious corundum is to be achieved, carbon can no longer be readily used as a reducing agent or cannot be used at all, since at about 1800 DEG C aluminium carbide starts to form. According to the procedure used hitherto, the higher Al2O3 content is achieved by replacing the bauxite partially or wholly by alumina. The principle of the invention is still to smelt bauxite, rather than alumina which carries a high production cost, but to use a reducing agent which does not form aluminium carbide. In this context, aluminium is particularly suitable as a reducing agent. An essential characteristic of the aluminothermic process is found in the fact that upon complete reduction of bauxite a corundum with a content of  alpha -Al2O3 >/= 99% is produced, as had hitherto only been achieved in the single-crystal corundum according to the HAGLUND process. The production costs of the corundum prepared according to the aluminothermic process are about 40% less than that of the ... from "BAYER" alumina ... Original abstract incomplete.

Title: Device for receiving and processing baked articles
Inventor: BERIE JOHANNES
IPC: A21B5/08
Filed: 1984-07-31
Abstract: The invention relates to a device for receiving and processing baked articles, especially baked articles made of yeast dough. In the manufacture of dumplings in particular, each lump of dough has had to be individually moved by hand several times from the start of the process, i.e. between the metering out of the as yet unrisen dough and removal of the fully baked dough from the baking liquor. This has proved to be an extremely onerous task, particularly in mass production. The metered out quantities of dough now only have to be inserted in the device according to the invention, without having to be moved for rising and baking. This does not just considerably reduce the time it takes to complete the manufacturing process; it also permits the even baking of all portions of dough situated in the device. <IMAGE>

Title: Method for determining the state of earthing of isolated electrical lines
Inventor: HECHT SIEGFRIED DIPL ING
IPC: G01R31/02
Filed: 1984-08-08
Abstract: Before an isolated high-tension line is added into an energy supply system, previous earthing must be cancelled. The unearthed state is indicated by position detectors on the earthing switches. This position detection by earthing switches is not sufficient for obtaining unequivocal information on the state of earthing, especially in automated system operation. According to the invention, the object of specifying a method for checking the earthing state, which is independent of this detection, is achieved by the fact that electrical power with an audio frequency and low voltage is fed into the isolated line (4) and information on the state of earthing is obtained on the basis of a measurement of the feed line, for example an active-power measurement. When the line (4) is earthed, an injected measuring current (active current) flows back via the earth to an audio frequency generator (12) and allows, for example, a wattmetrical relay to operate in a wattmeter (11). <IMAGE>
