Patent DE-3138134-A1 (DE)
Title: Method of grinding workpieces and device for carrying out the method
Inventor: MEYER OTTO
IPC: B24B1/04
Filed: 1981-09-25
Abstract: A method of grinding workpieces, e.g. glass or hard metals, with a holder for the workpiece, a feed mechanism and a grinding head and an abrasive-feeding device. In precision NC-controlled grinding and polishing machines, a hard-to-explain correlation between smooth running and the operating result often appears. This is often less satisfactory than in less accurate conventional machines. To improve the result of such operating methods, it is proposed that a relative movement be superimposed by oscillations via the rotational or oscillating movement between workpiece and grinding tool.

Title: Closing-sequence controller for a two-wing door
Inventor: SLOGSNAT UDO
IPC: E05F5/12
Filed: 1981-12-21
Abstract: The invention relates to a closing-sequence controller which can be used especially on two-wing fire doors, in order to ensure that first the so-called standing wing and thereafter the gangway wing are always closed in the correct sequence. The closing-sequence controller consists of two toggle levers, of which the inner arms directed to the door are connected to one another in the manner of a rectilinear sliding pair or with the same effect in terms of transmission. At the same time, the lever assigned to the gangway wing is adjustable in the length of its free arm and the pivoting range of one of the levers is adjustable. As a result of the positive connection according to the invention of the two toggle levers, the adjustability of the length of the lever arm assigned to the gangway wing and the adjustability of the pivoting range of one lever, preferably of the lever assigned to the standing wing, it is possible, with such a closing-sequence controller of one constructional size, to control door wings of spring-loaded two-wing fire doors, after appropriate adaptation, in such a way that, in the closing phase, the gangway wing always reliably lags behind the standing wing.

Title: Process for producing galvanic cells having negative alkali-metal or alkaline-earth-metal electrode coated with a passivating layer
Inventor: ALPEN ULRICH VON DR
IPC: H01M4/12
Filed: 1982-01-19
Abstract: A temporary protective layer on negative alkali-metal and alkaline-earth-metal electrodes of galvanic cells is produced during cell assembly and storage by an impregnation treatment with a solution of the butyl compound of the metal (Li, Na, K, Ca) concerned in a low-boiling hydrocarbon, for example n-hexane. After the solvent has evaporated, the butyl compound left behind on the electrode surface reacts in an argon atmosphere with traces of O2 and H2O contained therein to form a homogeneous coating layer composed of the oxides and hydroxides of the electrode metal. This layer does not obstruct immediate activation of the cell on completing the circuit.

Title: Connection unit for joining two guide bars which can be attached to the floor
Inventor: BAYR JOHANNES
IPC: A47F10/04
Filed: 1982-01-23
Abstract: In self-service shops, expensive shop furniture is bordered by means of guide bars which can be attached to the floor to protect it from damage which can be caused by shopping trolleys. Previously, a right-angled course of guide bars has only been produced in a satisfactory manner by single-part connecting pieces. However, these connecting pieces cannot be used for an acute-angled or obtuse-angled course. The invention therefore discloses a connecting unit (1, 1') for joining two guide bars (14) which can be attached to the floor, which unit is designed as a joint which can be pivoted about a vertical axis, each half (2, 2') of the joint being connected to one guide bar (14) in each case. As a result, a multiplicity of acute-angled or obtuse-angled guide bar arrangements can be produced.   <IMAGE>

Title: Auxiliary device for overhead projectors for simultaneous projection of two mutually perpendicular object planes
Inventor: JAEKEL-FESSENMAIER CHRISTIAN D
IPC: G03B21/132
Filed: 1982-07-28
Abstract: Only a horizontal object plane is sharply imaged by overhead projectors. For the purpose of sharply imaging a horizontal and a perpendicular object plane of a spatial object, an auxiliary device is mounted on the projector in which a portion of the beam path is deflected by a mirror system such that the object is transirradiated in an additional perpendicular plane, and this light is then once again reflected into the old beam path. In order to improve the imaging characteristics, the mirrors can be constructed as front-surface mirrors or as totally reflecting prisms, it being the case that in order to correct the magnified object width in the reflected beam path an optical correction system is inserted or formed by the mirrors.

Title: Process for the anaerobic treatment of sludges and waste waters
Inventor: LIEPE FRIEDRICH PROF DR
IPC: C02F3/28
Filed: 1982-08-02
Abstract: The invention is used in the continuous anaerobic treatment of sludges and waste waters which have a high content of organic substances, such as for example in the case of intensive animal husbandry. The invention is particularly suitable for heavily contaminated sludges and waste waters. The object of the invention is to create an apparatus in which a single-stage or two-stage anaerobic degradation can be carried out with high intensity, the heat losses and the temperature differences being minimised by compact construction. The apparatus according to the invention comprises a cylindrical vessel which has a reaction chamber for carrying out the methane fermentation and a separation chamber where separation effects resulting from sedimentation and flotation are utilised. As a result of expedient arrangement of passageways in the lower part of the wall separating the reaction chamber and the separation chamber from each other, return of sludge into the reaction chamber is permitted and undesired circulation of the liquid is avoided. The reaction chamber and the separation chamber have a common gas collecting chamber above them. Thickened sludge can be withdrawn from a sludge collection chamber in the lower part of the separation chamber. <IMAGE>
