Title: Method and device for sterilising a quantity of liquid, in particular a quantity of water
Inventor: ANKE WALTER
IPC: C02F1/461
Filed: 1983-11-19
Abstract: A completely problem-free application which is associated with little expenditure of time is ensured in a method of sterilising a quantity of liquid, in particular a quantity of water, if an electric current is passed for a specified minimum time through the quantity of liquid to be sterilised. Even an electric current of less than 1.0 A for a time of substantially less than 30 min is sufficient to completely sterilise a quantity of water bacteriologically and virologically. The current should be passed through the liquid using a carbon anode and a silver or platinum cathode. A suitable device expediently comprises a liquid container (1), an anode (2) projecting into the liquid container (1), a cathode (3), and a current source (4), in particular a battery, connected to the anode (2) and the cathode (3). The components of such a device can readily be integrated so that the device as a whole has the outward appearance of a "normal" drinking beaker. <IMAGE>

Title: Seed-spacing drill
Inventor: LINK ALFRED ING GRAD
IPC: A01C7/04
Filed: 1983-12-02
Abstract: In a seed-spacing drill, a seed loosener is provided in front of the seed outlet (7), as seen in the direction of rotation of the cellular wheel (3). This seed loosener consists of a band (10), the end of which is spread away from the inner cylindrical surface (11) of the housing (1) of the seed-spacing drill by means of a setscrew (13). As a result of this design, the seed grains (13) come up against the spread-away part of the band before reaching the seed outlet (7) and are thereby moved into their cells (9, 9'). Jams which possibly occur are cleared in this way, so that the seed grains (12), when they reach the seed outlet (7), easily fall through this. <IMAGE>

Title: Thermal steam trap
Inventor: BOEHM LOTHAR DIPL ING
IPC: F16K17/38
Filed: 1984-01-25
Abstract: The invention relates to a thermal steam trap which is equipped with a control element (a diaphragm capsule), which is of flat construction, is filled with control fluid and is in the form of a plate, and which is used for dissipation of the condensate forming on it in steam-operated systems. The thermal steam trap according to the invention is intended to ensure economical utilisation of the heat energy of the energy carrier (steam) for the heating and technological process, with a small and simple construction, an increased life in comparison with known and comparable apparatuses being achieved as a result of special shaping of the diaphragm and of the upper wall part in the centre. 
<??>This is achieved in that the diaphragm and the upper wall part are in each case provided with a circular bead in the centre, which bead encloses a flat diaphragm surface and a surface of the upper wall part, the diaphragm, which is thus stabilised in the centre, simultaneously acting as a sealing device, and the corresponding construction of the upper wall part in the centre being used as an upper opposing bearing for the diaphragm and supporting the latter against overloads.

Title: Method for monitoring room areas, and light barrier
Inventor: EISENREICH NORBERT DIPL PHYS D
IPC: G08B13/183
Filed: 1984-06-23
Abstract: A method for monitoring room areas by means of a light barrier having a laser light source (1) and a receiver having at least one photosensor, and a suitable light barrier is proposed which should be reliably insensitive to interfering light. In this method, this is achieved by the fact that the light intensity of the laser is modulated by piezoelectric misalignment of the resonator, and the light intensity-modulated in this manner is filtered out in the receiver circuit. The light barrier is constructed in such a manner that the resonator (7) of the laser (6) is provided with a vibration generator (13). Method and light barrier are used particularly advantageously in large-area surveillances over long distances. <IMAGE>

Patent DE-3431841-A1 (DE)
Title: Method for monitoring a digital incremental measurement-value pickup
Inventor: MEISTER WERNER ING GRAD
IPC: G01D5/245
Filed: 1984-08-30
Abstract: To monitor digital incremental measurement-value pickups, it is known, when the reference pulses of the measurement-value pickup arrive, to determine the extent to which the pulse number output is correct via a counter comparison. However, this usually only provides for adequate monitoring if the reference pulses are also additionally monitored. This monitoring is expensive and difficult when the speed changes. In an inverse method according to the invention, the reference pulses are now monitored after a predetermined number of measurement value pulses have arrived. A direction-of-travel-dependent counting comparison - after preceding synchronisation - can be used, together with the monitoring of the reference pulses, for obtaining an equivalent monitoring of the measurement value pulses at different rates of travel and also with a change in the direction of travel.

Title: Nail-driving tool with a driver centrally symmetric in cross-section
Inventor: SIEGMANN CARL
IPC: B25C1/00
Filed: 1985-02-23
Abstract: In the driver passage of a compressed-air nailer with a driver of repeatedly centrally symmetric cross-section, a stop for the head of the frontmost nail in each case is provided opposite the entry slot with which the nail magazine leads into the driver passage. The stop is designed in a strip shape parallel to the driver axis and engages in a corresponding recess of the driver. In this way, the head of the frontmost nail is first of all inserted into the driver passage only to such an extent that the head of the following nail overlapping it is not struck by the driver when the latter drives in the first nail and in the process causes it to pass into a coaxial position relative to the driver by means of a sloping nail-head guide leading into the driver passage.

Title: Method and arrangement for transmitting information
Inventor: DRUDE STEFAN
IPC: G08C25/02
Filed: 1985-03-11
Abstract: When information is transmitted via infrared light signals, for example in the case of a remote control for a broadcast or television receiver or in the case of a keyboard for a computer, interference can occur which prevents the correct reception of the information in the processing device. To ensure undisturbed operation in the most frequent case of a temporary interference, the received command signal or a state triggered by it is transmitted back to the operating unit from the processing device and when this retransmission does not occur within a predetermined time, the same information is sent out again by the operating unit. It is only when the new transmission or a predetermined number of successive new transmissions is not successful that this is reported to the user. <IMAGE>

Title: Reflector arrangement and film-viewing device formed thereby and having adjustable brightness
Inventor: HAEHNEL CLAUS
IPC: F21V9/40
Filed: 1985-07-11
Abstract: Examples of applications for illuminating devices whose brightness can be adjusted are dental X-ray film viewers or workstation luminaires. In known illuminating devices with fluorescent tubes, the latter are either dimmed by means of electronic ballasts or are partially switched off, in order to vary the brightness. Another known possibility for varying the brightness consists in the successive occultation of a portion of the optical radiation impinging on a reflector. According to the invention, it is now to be possible to vary the brightness of an illuminating device by varying the reflectance behaviour of its reflector. For this purpose, the total reflecting surface of a reflector is subdivided into subareas of different reflectivity, and the subareas are adjustably arranged for the purpose of varying fractional areas of the subareas located in the beam path of the light source.
