Title: Tempering rotary kiln gases - with cold cement and coolant to prevent alkaline deposits in preheater
Inventor: ABELITIS ANDRIS DIPL ING
IPC: F27B7/20
Filed: 1980-12-02
Abstract: The materials in the exhaust gas from rotary kilns, used for the thermal treatment of raw cement meal and which tend to form unwanted cpds. and in particular the alkalis, S and Cl are cooled to a temp. below the critical fusion temp. of such cpds. by feeding into a long kiln the cold cement meal and a gaseous and/or liq. coolant, esp. water and/or air. The cement can be fed as an air suspension into the exhaust gas, e.g. in fluidised form, and the furnace gas is cooled to below 500 deg.C. 40-100% of the raw meal needed for clinker prodn. can be supplied to temper the exhaust gas. Used for cement mfg. plant esp. in countries where raw materials can have high alkali contents, available fuels a high S content, and cooling water is not readily available. This prevents gradual build-up of deposits in film pre-heater.

Title: Accumulator cell with recombiner, external oxygen supply and electrolyte circulation
Inventor: LEDJEFF KONSTANTIN DIPL PHYS D
IPC: H01M10/52
Filed: 1981-02-12
Abstract: Accumulator cells (1) which are in a battery assembly and have devices (2) for oxyhydrogen recombination are accessible through an intrinsically closed system of gas supply lines (3) and gas outlet lines (4) both to an oxygen supply from an external steel cylinder (bottle) (8) and to gas-operated electrolyte circulation, in that the oxygen is at the same time used as the operating gas for the compression pump (5) with an output (6) on the pressure side and a suction connection (7). If the cell gassing predominantly contains oxygen, oxygen is blown out through an overpressure valve (10), while a hand-operated valve (11) simplifies purging of the system with oxygen. <IMAGE>

Title: Heating device for metal-vapour lamps for achieving and maintaining a standby mode
Inventor: NIGG JUERG
IPC: H01J61/52
Filed: 1981-03-18
Abstract: The invention relates to a pre-heating device for metal-vapour lamps in order to make said lamps immediately available with their full light power. At the same time, the device is used for energy saving. In one embodiment, the metal-vapour lamp rests in a radiation furnace, which is insulated from the exterior, from which it is moved into the focus-point position of the main mirror in order to emit light after the lamp current has been switched on. Another embodiment heats the metal-vapour lamp by means of so-called soldering lamps. These are small infrared radiators having an elliptical mirror. A special embodiment provides that the metal-vapour lamp is arranged at the focus point of a cold-light mirror and is heated at the sides by the aforementioned soldering lamps (which radiate infrared) through the mirror system, through which infrared can pass, at whose second focus point the metal-vapour lamp to be heated is located. In this case, no kinematics are required.

Title: Arrangement for generating, amplifying or synchronising radio-frequency power, in particular in the millimetre-wavelength range
Inventor: BARTH HELMUT DIPL ING
IPC: H03B9/14

Patent DE-3117660-A1 (DE)
Title: Rechargeable electrochemical cell, especially battery
Inventor: BUSS DIETER H DR
IPC: H01M10/42
Filed: 1981-05-05
Abstract: If during electrolysis metals are deposited from aqueous solutions, the development of non-uniform deposition types or moss- or sponge-like formations may result in short circuits with the counter- electrode or an inserted separator. Known separators which are designed to be metallically conductive, trigger, upon contact with the metal of the negative metal electrode, the inhibited hydrogen evolution and thus terminate the charging operation as a whole. In order to overcome these drawbacks, a separator is inserted which, or whose surface, does not have continuous metallic conductivity and consists of substances which, in contact with the metal of the negative electrode, are reduced to substances having a small hydrogen overvoltage and are then arranged, as mutually insulated individual electrocatalyst particles for hydrogen evolution, on the support material of the separator.

Title: Apparatus for feeding wooden boards
Inventor: WIEGAND KARL-WOLFRAM
IPC: B23Q7/16
Filed: 1981-05-09
Abstract: The apparatus represents a combination of roller conveyor and liftable turntable, the liftable turntable being arranged below the roller conveyor and only being moved up above the plane of the roller conveyor when the bundle of wooden boards is to be rotated through 180 DEG . Subsequently, the liftable turntable is lowered again, so that the roller conveyor can perform its normal function. As a result, the apparatus is compact and an additional manipulation to reload the bundle of boards onto a separate liftable turntable is unnecessary.

Title: Securities with substances, method and device for testing the latter
Inventor: KAULE WITTICH DIPL PHYS DR
IPC: D21H21/48
Filed: 1981-05-29
Abstract: The securities have luminescent originality characteristics which, after excitation with invisible light, emit solely invisible light of other wavelengths as originality signal. The luminophors can be added to the printing inks used or they can be applied to the paper fabric during its manufacture. A corresponding test apparatus allows the originality of the securities to be established in the presence of customers but unnoticed by them. In this case, the invisibility of the test signal and the originality signal is utilised and the test device is concealed behind a panel which is not permeable to visible light, but which is permeable to the test signal and the originality signal.

Title: Method for crosscutting a material web and stacking the cut sheets, and fly-cutter crosscutting apparatus for material webs with sheet deposit
Inventor: VITS HILMAR
IPC: B65H35/06
Filed: 1981-08-06
Abstract: The invention relates to the crosscutting of a material web and the stacking of the cut sheets. In order to overlap the sheets, braked to zero at the cutting point during the cutting operation, for the purpose of stacking, the cut-off sheet is conveyed on to the sheet deposit at normal conveying speed after the cutting, while the new start of the material web of the as yet uncut sheet is conveyed at increased conveying speed. In this way, not only an overlapping is achieved, but also the build-up of material web formed during the cutting is cleared.

Title: Auxiliary device for producing pairs of stereoscopic photographs using a single camera
Inventor: RIMOLDI LUIGI
IPC: G03B35/10
Filed: 1982-02-27
Abstract: The invention relates to an auxiliary device for producing pairs of stereoscopic photographs using a single camera. The auxiliary device consists of two parts: the plate having the two guide rails which run in a different manner, and the camera base guide shoe. The straight guide rail is used for producing stereo photographs when the object to be photographed is more than 2.5 metres away from the camera. The circular guide rail is used for every shorter distance. In consequence, the camera can pivot, fastened on the guide shoe, and always assume the correct inclination angle with respect to the object to be photographed. The camera base guide shoe carries out two functions: it holds the camera firmly on the respective guide rail by means of a stand screw which is fitted under the guide shoe, and guides the camera into the desired position. This combination of plate and guide shoe with a camera allows the production of stereo photographs from non-moving objects without using special stereo cameras or optical additional devices.

Title: Sample melting device
Inventor: OSTERMAY GOTTFRIED DR ING DIPL
IPC: B01L3/04
Filed: 1982-03-26
Abstract: The invention relates to a sample melting device consisting of a graphite crucible and an associated crucible carrier, for use for gas analyses in metals. A high melting effectiveness, with outgassing of the metal sample, is to be achieved at the lowest possible energy supply. The shape of the graphite crucible is such that the melting temperature is reached in the region of the crucible where the sample is located. The graphite crucible is of hollow cylindrical shape in its upper portion and has a relatively thick floor. The transition from the external diameter of the cylindrical portion to the external diameter of the floor, which is smaller, is provided with a radius with respect to the longitudinal axis of the crucible. A surface of small cross section, and thus high electrical resistance, then arises at the height of the floor of the internal bore, so that a high temperature is reached when a current is passed through. <IMAGE>
