Title: Working method for installing and removing the set of moulds which is composed of an upper mould and a lower mould in the case of a plate press for producing press plates
IPC: B30B15/02
Filed: 1993-03-03
Abstract: Working method for installing and removing the set of moulds which is composed of an upper mould and a lower mould and is provided with complementary pressing surfaces, in the case of a plate press with a hydraulic drive system for pressing tabular material to be pressed, during the production of press plates. Work is carried out with a mould changing carriage which has a raising and lowering device with a hydraulic drive. The mould changing carriage is moved by means of a chain drive which is arranged in front of the plate press and extends from the starting station itself up to the front of the plate press. In order to install a set of moulds, the appropriate batch of moulds is, in the starting position, placed on the mould changing carriage in the correct position for fitting and is moved into the open plate press, ready for accurate installation. The hydraulic drive of the raising and lowering device of the mould changing carriage is connected to the hydraulic drive system of the plate press and the mould changing carriage together with the batch of moulds is raised in the open plate press until the surface rests against the rolling beam and the upper mould and the lower mould are fastened thereto. The mould changing carriage is released from the batch of moulds, lowered and returned out of the open plate press. The batch of moulds is lowered using the running beam until the lower mould rests on the bed plate. The lower mould is connected to the bed plate and is released from the running beam and/or the upper mould and the plate press is made ready for operation thereby ...

Title: Method for measuring welds (seams, welded seams)
Inventor: BARTHEL KLAUS DR
IPC: B23K9/127
Filed: 1993-04-15
Abstract: This method serves for measuring welds for the purpose of being applied in a weld-tracking system. In this case, the surface of a workpiece is illuminated in the region of the weld (weld region) and recorded by a planar image recorder with the interposition of an optical system. A striped pattern is projected obliquely in relation to the optical axis onto the weld region (light section method). In order to be able to measure the position even of a fine weld without a pronounced jump in height in an automatic fashion, it is provided that the projection of the striped pattern is performed intermittently. In this process, the position of the surface is determined from the striped image in a three-dimensional coordinate system referred to the optical system during the projection phases, and the position of the weld on the surface is determined by grey image evaluation between the projection phases.

Title: Valuable metal selective sepn. without jarosite or double salt formation - by neutralising organic extn. soln. and exchanging ammonium or alkali ions in extractant with metal ions before main extn. stage
Inventor: NYMAN BROR GOERAN
IPC: C22B23/00
Filed: 1993-06-18
Abstract: In the selective sepn. of valuable metals (I) in a solvent extn. stage of an acid lixiviation process, the formation of jarosite and ammonium or alkali double salts is prevented by (a) neutralising the organic extn. soln. (II) with ammonium or alkali salt before the main sepn. of (I) by solvent extn.; (b) pre-extn. of (II) by contacting the extractant (III) with an aq. soln. contg. a metal (IV) as exchange ion to replace ammonium or alkali ions in (II); and (c) contacting (II) with the aq. soln. contg. (I) in a main extn. stage. Pref. (III) is a di-(alkyl)-phosphinic acid ( IA), pref. a di-(2,4,4-trimethyl-pentyl)-phosphinic acid (IIIA-1), a monoalkyl ester of an alkylphosphonic acid or a di-(alkyl)-phosphoric acid; and (IV) is Mg. At least one (I) is more strongly extracted than (II), so that the latter is returned to the aq. soln.; and at least one (I) is more strongly extracted than other (I). The most strongly extracted (I) is Co (in mixts. with Ni) or one of Zn, Mn, Cd, Cu, Fe, V, Mo and U, esp. in mixts. in which the least strongly extracted is Cu or Mn. USE/ADVANTAGE - The process is useful in the sepn. of Co and Ni or of Zn, Mg, Cd, Cu, Fe, V, Mo or U, esp. from Cu or Mn (claimed). Removal of ammonium and alkali ions makes it possible to use higher temps. to intensify the lixiviation process and protects the environment.

Title: Detecting device for information data during the reception of a broadcast signal
Inventor: GO JIN GON
IPC: H04N5/44
Filed: 1994-07-29
Abstract: A receiving device for a broadcast signal is specified for the purpose of monitoring a broadcast RF signal which has information data such as, e.g., VPS (Video Programming Service) data in a video signal from a transmitting station. The device demodulates the broadcast signal of a selected channel and has a device for detecting the information data during the reception of the broadcast signal with a VPS part for the purpose of separating and detecting the information data in the demodulated video signal, and of providing the detected information data. The device further has a microcomputer for controlling a preprogrammed recording in conformance with the information data from the VPS part, and a fault prevention unit for exclusive separation of a colour synchronising signal (pulse) from the returned video signal during detection of the information data by the VDS part, and for the purpose of preventing a fault by controlling the rate of amplification of an intermediate frequency in conformity with the separated colour synchronising signal level. By improving the frequency characteristic during the amplification of the intermediate frequency signal and of the noise response and frequency response of the video signal, the edge characteristic of the pulse signal (sampled signal) for the information data which are contained in the video signal is improved, with the result that a fault is prevented from arising during the detection of the information data, as a result of which faulty functioning of a video camera during the execution ...

Title: Optical transmitting and receiving module and optical communication system using this
Inventor: OHNISHI KUNIKAZU
IPC: G02B6/42
Filed: 1994-10-07
Abstract: What is disclosed is a bidirectional optical transmitting and receiving module of a simplified structure and an optical communication system which uses this module. The optical transmitting and receiving module has a light-transmitting device and a light-receiving device which are arranged inside the same housing which has an opening which is covered by means of a cover glass, as well as a holographic diffraction grating provided on an upper or lower surface of the glass pane. During transmission, a light beam emitted by the light-transmitting device penetrates the diffraction grating in order to be focused, by means of a lens, on an end surface of an optical fibre. During reception, a received-light beam leaving the end surface of the optical fibre reaches the diffraction grating via the lens in order to be diffracted thereby. A diffracted main light beam having a plus sign resulting from the diffraction is focused on a light-detecting surface (light-measuring surface) of the light-receiving device. In this way, a signal can be received in the same way as it is transmitted through the optical fibre in the form of a light signal.

Title: Sewage pipe repair method
Inventor: GAERTNER MANFRED
IPC: E03F3/06
Filed: 1994-10-21
Abstract: The pipe is cleaned and a helically wound replacement pipe (1') is then moved to the point to be repaired, and pressed against the wall of the original pipe. The replacement pipe is held together by hooks (15,16). These are released, and cause the pipe to expand and increase its diameter. Two end faces of the replacement pipes are locked in place relative to each other, joining the pipes together end-to-end. An insertion device is then removed from the replacement. Alternatively, a cord is shot through the pipe to be repaired by a bolt, and this draws the replacement into it. This is then expanded by a compressed air bag, and the replacement locks into its final position.
