Title: Method of cooling molten calcium carbide
Inventor: PIETZARKA FRIEDRICH WILHELM DR
IPC: C01B32/942
Filed: 1983-04-22
Abstract: The invention relates to a method of cooling molten calcium carbide from a carbide furnace. Carbide is produced in a carbide furnace from the charge materials lime and coke, coke being used as carbon carrier. The process for the production of calcium carbide requires a high expenditure of heat, in the form of electrical energy, per unit weight of product. While some of the heat expended is recovered as heat of reaction, the rest, about 27% of the total amount expended, appears as latent heat in the molten calcium carbide. In order to use some of this high-temperature heat, a fine-grain mixture of solid reactants from the starting substances is admixed with the molten calcium carbide emerging from the carbide furnace. This mixture is converted virtually completely into carbide.

Patent DE-3318919-A1 (DE)
Inventor: FISCHER PETER
IPC: H04H60/31
Filed: 1983-05-25
Abstract: In order to gather information on the reception of video channels in a household or other location equipped with a television receiver, partinent data such as identification and viewing time are injected into an assigned minor area of the TV picture at the receiving location. The injected data, appearing in digitized form in the assigned area where the TV picture has been blocked out, are picked up by a photosensor juxtaposed with the CRT screen of the receiver, or possibly from a video output thereof, and are fed to a processor for transmission over a telephone line with or without intermediate storage to an evaluation center. A data injector inserted between an antenna and an input terminal of the receiver blanks the incoming video signal of a selected channel during a small fraction of a frame-scanning cycle, while the CRT beam sweeps the assigned area, and replaces it with the digitized data. Alternatively, the blanking of the assigned area and insertion of channel identification may take place at the transmitting station.

Patent DE-3329470-A1 (DE)
Title: Process for determining the coefficient setting values of an equalizer
Inventor: LINDNER JUERGEN DR ING
IPC: H04L25/03
Filed: 1983-08-16
Abstract: For determining the coefficient setting values of an equalizer for data transmissions over linearly distorting, time-invariant or slowly time-variant message transmission channels, over which messages are transmitted by the single-sideband, vestigial-sideband or double-sideband method without carrier, in which methods the messages are transmitted preferably in the form of data blocks and a sequence of test signals is in each case sent out before each data block and, on the receiving side, a quadrature demodulator and an equalizer are used, a channel-correlation filter being connected between the modulator and equalizer, and from each sequence of test signals the unit pulse response of the transmission link is determined on the receiving side and, with the aid of the unit pulse response, the setting of the channel-correlation filter is performed or corrected, it is proposed to simulate in the receiver a transmission link having the known and continuously updated channel unit pulse response. A sequence of periodically recurring one symbols is transmitted via the simulation and the setting of the coefficients of the equalizer is performed using the resulting output signal of the simulation. The equalizer can thus be adapted in real time, in particular with a programmable processor, resulting in short adaptation times.
Patent DE-3336325-A1 (DE)
Title: Improved installation system for a WC, bidet and the like
Inventor: HACK GUENTER
IPC: E03D11/16
Filed: 1983-10-06
Abstract: An improved installation system for a WC, bidet and the like is achieved, inter alia, by dividing the bowl, e.g. into a base and an element which rests thereon. In this arrangement, the base of the bowl is designed as a floor tile which is adjoined in a flush manner by the tile covering of the floor. The lower bowl joint can be arranged on this floor tile above the floor and at the height of the base, and can be designed in such a manner that it remains dry when the floor is cleaned, as a result of which the current floor joint, which is a breeding ground for bacteria and is continually wet and unhygienic, is avoided. A further advantage of this divided bowl consists in the fact that the floor tile, located in the floor covering, is provided with fittings which allow the prior sanitary installation of water supply and drainage means in said tile, as a result of which the associated, correspondingly designed bowl can simply be placed on this pre-installed floor tile at any given time. Better hygiene is, furthermore, achieved if the currently concealed flushing-water supply duct in the upper bowl rim is relocated in the raisable seatring, where, as an open channel, it is accessible for cleaning. <IMAGE>

Title: Through-tunable Cr-Al-Garnet lasers and Cr-sensitised Nd-Al-Garnet lasers
Inventor: HUBER GUENTER PROF DR
IPC: H01S3/16
Filed: 1983-11-23
Abstract: The invention describes novel Cr<3+>-doped and Cr<3+>/Nd<3>+-codoped aluminium garnet crystals for through-tunable solid state lasers in the near infrared spectral range and efficient Nd<3+> lasers with sensitisation by Cr<3+>. For Cr: Gd3Sc2Al3O12, continuous-wave laser operation at 780 nm was demonstrated. Described as an exemplary embodiment for Cr<3+>-sensitised Nd<3+> lasers are Cr,Nd: Gd3Sc2Al3O12 and Cr,Nd: Y3Sc2Al3O12. As a result of codoping with Cr<3+>, the pumping light of broad-band lamps is used more efficiently in this instance than with crystals doped purely with Nd.

Title: Membrane filter plate
Inventor: NEU WERNER DR ING
IPC: B01D25/168
Filed: 1984-01-31
Abstract: The invention relates to a membrane filter plate, composed of a base plate furnished with through-holes for the slurry inlet and filtrate outlet and furnished with recesses and at least one membrane having smaller surface dimensions which lies under the filter pressure on the surface of the recess designed for the uptake of the material to be filtered in the form of a pot-shaped recess and the swallow-tailed edge bead of which membrane is inserted into an annular recess which runs approximately parallel to the sealing edge of the base plate. It is the object of the invention to achieve correct fixing of the membrane on the base plate of the membrane filter plate in order to spare this and prevent damage to it. The invention achieves this in that the edge bead is arranged unsymmetrically to the central plane of the membrane on the side of the membrane facing the base plate and in that the edge of the pot-shaped recess runs parallel to the sealing plane of the base plate, extends to the annular swallow-tailed recess and runs displaced by about the thickness of the membrane to the edge plane of the base plate.
