Title: Removing ions from liquid streams - by passing through tubular vessels and applying an electric field normal to the direction of flow
Inventor: KLASSERT ANTON
IPC: B01D57/02
Filed: 1977-12-22
Abstract: Ions are removed from a fluid stream by allowing the fluid to flow in such a manner into a non-conducting (pref. tubular) chamber that it completely fills it. An electric field is applied normal to the direction of flow over a sufficient length of the chamber to effect a sepn. of ions from the fluid. The flow is then divided so as to obtain one ion-paper or -free fluid stream and one ion-enriched fluid stream. The method is useful for desalting seawater and/or industrial effluents as well as to reduce the acid content of fruit juices and wines. Plant costs and upkeep are reduced.

Title: Start-of-message generator for facsimile transceiver - describes mode of operation using clock pulses between two synchronisation words
Inventor: ROSENHECK BERNARD
IPC: H04N1/333
Filed: 1978-07-13
Abstract: The start-of-message generator selects one special mode from amongst several modes of operation each having a given code. The selected mode is coded. A start-of-message sync. word is generated and immediately afterwards a clock is triggered to produce a selected number of clock pulses depending on the coded selected mode of operation. At the end of the clock-pulse train a second sync. word is generated. A start-of-message decoder receives the first and second start-of-message sync. words. The clock pulses are counted by a counter which is enabled in the time interval between the sync. words. The number of counted clock pulses is translated back into the selected mode of operation.

Title: Angle or rotation instrument - has plane inclination pick=ups with two inclination detectors with output signal of one of them divided by pick=up output signal
Inventor: HENSING PETER ING GRAD
IPC: B66C23/90
Filed: 1978-09-11
Abstract: The device is intended for a crane lower and upper parts which can be at any angle to the horizontal. The rotation of the upper w.r.t. the lower part is measured. A plane inclination pickup has at least two inclination detectors mounted on the upper part (1). They detect the inclination of the upper part plane of rotation to the horizontal, independently from its rotation. The upper part (1) rotation w.r.t. the lower part (2) is measured by provision of a link between the outputs of one of the inclination detectors and the plane inclination pick-up. The output signal of the former is divided by the output signal of the latter thus producing the angle of rotation.
Patent DE-2848379-A1 (DE)
Title: Anti-theft device for motor vehicle - prevents shorting of ignition switch by using ignition-switch lock as bonnet lock
Inventor: EICHENAUER RUDOLF
IPC: B60R25/04
Filed: 1978-11-08
Abstract: The anti-theft device has the lock for the ignition switch (15, 16) also acting as the lock (2, 29) for the vehicle's bonnet. The cable connections for the ignition switch are located beneath the bonnet. Both the bonnet and the ignition switch are locked by a removable bolt lock of standard commercial design. An electrical contact device switches the vehicle's horn into the ignition circuit when the ignition current is switched off. A thief can therefore no longer short circuit the ignition switch by lifting the bonnet.
Patent DE-2848512-A1 (DE)
Title: Reducing oxazole content of acrylonitrile - by scrubbing, distn. combining side-stream with scrubbing water and expelling oxazole with residual gas
Inventor: ELISCHER STEFAN DIPL CHEM DR
Filed: 1978-11-08
Abstract: Acrylonitrile having a low oxazole content is prepd. by scrubbing the gaseous reaction mixt., leaving the reactor, with water, in an absorption column, (A), and distilling the absorption soln. in a solvent extn. column, (B) to recover crude acrylonitrile while an oxazole-rich side-stream is removed from column bottom. Novelty consists in removing a gaseous side-stream from the distn. section of the solvent extn. column (B) and combining it with the scrubbing water charged to the absorption column head (A). The oxazole present in the scrubbing water is expelled, from column head, by means of the residual gas and discharged with it. Oxazole and isoxazole content can be reduced to 5 ppm, e.g. 2-3 ppm, compared with 100 ppm without removing the gaseous side-stream. MeCN content can be reduced simultaneously to =1 ppm.

Title: Line protection switch - has arc extinguishing loop formed by magnetic release coil near arc guide rail
Inventor: DOERRIES ALEXANDER DIPL ING
IPC: H01H73/18
Filed: 1978-11-09
Abstract: The line protection switch has a contact arrangement forming an extinguishing loop. The fixed contact is formed by an arc guide rail on the magnetic return piece of the magnetic release coil. An extra loop is formed by that part (1b) of the magnetic release coil (1) running parallel to the contact region of the arc guide rail (3). Since the extra loop is formed by part of the release coil itself and is located in the space occupied by the arc guide rail, the switch may be relatively flat and compact.

Title: Hydraulically actuated forging hammer - uses force due to gas compressed by free piston to return main piston
Inventor: BALTSCHUN HORST
IPC: B21J7/46
Filed: 1979-02-06
Abstract: A hydraulically operated forging hammer is connected to a piston (3) by the piston rod (2). The piston operates with an annular clearance (6) inside a cylinder (1) which houses a free piston (5). The free piston is fitted below the main piston. Gas in the lower space (7) is compressed by the free piston as it is forced downwards by hydraulic fluid admitted into the annular space (6). When hydraulic fluid is admitted into the space (8) it pushes the main piston downwards for the working stroke. After completion of the working stroke the gas pressure in the lower space (7) returns both pistons to their initial positions.
