Patent DE-3833452-A1 (DE)
Inventor: KORNHAAS WOLFGANG
IPC: G11B23/36
Filed: 1988-10-01
Abstract: Method of avoiding the inadvertant overwriting of video signal parts recorded on a video magnetic tape and video magnetic tape recorder for carrying out this method. In known methods a mechanical switch mounted on the magnetic tape cassette casing is repositioned or a plastic tab fastened to the magnetic tape cassette casing is broken out. It is intended that the new method will not rely on mechnical means on the cassette casing. Furthermore, it is intended that in the new method it will be possible to decide individually for each recording on a video magnetic tape whether it should be overwrite-protected or not. For this purpose, it is tested before each recording whether the control track of the video magnetic tape already has control track pulses having a characteristic coding or not. If this is the case, the already effected recording will be identified as overwrite-protected and overwriting of this recording will be prevented. If this is not the case, the control track pulses associated with a new recording to be protected will be recorded with a characteristic coding. Video magnetic tape recorder <IMAGE>
Patent DE-3835597-A1 (DE)
Title: Method of determining sodium chloride in concrete paths
Inventor: LUBER WILLIBALD
IPC: G01N33/38
Filed: 1988-10-19
Abstract: The method of the invention makes it possible to carry out a test for the presence of sodium chloride in concrete by means of drilling dust (bore dust, boring dust) at the building site. A concrete mixture comprising drilling dust and water, which has been exposed to sodium chloride stress, is compared with that from a protected region. From the differing conductivity of the electrical measuring current, the chloride can be detected and the content can be estimated from the difference. It makes possible, at the building site, a rapid analysis and thus a rapid aid for making a decision.

Patent DE-3901359-A1 (DE)
Inventor: KAPLAN MURRAY ARTHUR
IPC: A61K31/545
Filed: 1989-01-18
Abstract: Crystalline sulfuric, di-nitric, mono-hydrochloric, di-hydrochloric, and di- and sesqui-orthosphosphoric acid addition salts of 7-[ alpha -(2-aminothiazol-4-yl)- alpha -(Z)-methoxyimino-acetamido]-3-[(1-methyl-1-pyrrolidinio)methyl]-3-cep hem-4- carboxylate are stable even at elevated temperatures. The crystalline sulfuric acid addition salt is made by forming an admixture of (a) at least one molar equivalent of sulfuric acid with (b) zwitterion in an amount so as to be present in the admixture at a concentration of greater than 25 milligrams/ml, causing crystallization, separating the crystals, washing and drying. The crystalline monohydrochloride, dihydrochloride, and orthophosphate salts are prepared by dissolving the zwitterion in the appropriate amount of acid, causing crystallization by adding acetone and isolating the crystals. Physical admixtures of the salts with certain bases in proportions to give a pH ranging from about 3.5 to about 7 on dilution with water provide injectable compositions on dilution.

Patent DE-3906293-A1 (DE)
Inventor: LISEC PETER
IPC: B05B13/02
Filed: 1989-02-28
Abstract: In the device for coating distance-keeper frames for insulating glass, which possess corners which are bent in one piece, with an adhesive or sealing compound, the relative position between the connecting line of the openings of the nozzles (10) on the one hand and the axis about which the turning device (13, 14) can be swivelled on the other hand can be varied. This possibility for variation is achieved in that either the swivel bearing of the turning device (13, 14) is arranged so that it can be moved laterally or vertically up or down in the frame of the device, or in that the component part which supports the nozzles (10) is arranged so as to be movable vertically up or down in the frame of the device and the swivel bearing of the turning device is arranged so as to be movable laterally. As a result, the nozzles (10) remain aligned opposite the lateral faces of the distance-keeper frames even when the latter are being turned.

Patent DE-3910701-A1 (DE)
Title: Water heater
Inventor: FRIEDRICH PETER
IPC: F23N5/24
Filed: 1989-04-03
Abstract: A water heater has a heat exchanger (3), which is heated by a gas burner (2) and through which water to be heated flows, and at least one igniting and/or monitoring burner (8 and 18, respectively) which is automatically ignited by a water switch (1) at the start of each passage of water and is thermally monitored by a monitoring device (12). It is ensured in the water heater that in the event of a lack of gas in the tapping operation, renewed ignition can be blocked in order to prevent ignition in the combustion chamber, which is filled with gas which has not yet been burned. Such blocking guarantees that the monitoring device assigned to the ignition and/or monitoring burner (8 and 18, respectively) assigns only a single ignition operation to each individual water passage, that is to say to each individual tapping in the case of a service water heater. For this purpose, it is possible to provide in the ignition circuit (6) two switches (5 and 10) of which one (10) is assigned to the position encoder (11) of the thermocouple (12) and the other is assigned to the actuators (4) of the water switch (1) and which are arranged in series. The signals assigned to such switches (5, 10) can also be combined with one another logically by electronic means. It is also possible to connect the functions of such switches (44, 47) to one another mechanically, eg. to locking by means of a latch (78).   <IMAGE>

As a function of the output signals of the volumetric flowmeters (5) and (6) of the gas charging gauge (8) and of the adjustable, predetermined set value, a control device (9) actuates the valve (7) via a correcting element and thus continuously regulates the required volumetric flow of gas. <IMAGE>
