Title: Arrangement of electrodes for producing an electrical field in the region of combustible materials
Inventor: PICKL OTTO
IPC: F02P15/04
Filed: 1981-03-25
Abstract: Chemical reactions which are accompanied by light and heat phenomena are generally called flames. Considered elementarily, the "fuel" reaction partner has electrostatic valent charges which exert force on the "oxygen" reaction partner. Above a specific temperature, both materials have sufficient movement energy to shear existing bonds, to follow the electrostatic charge and to start the flame reaction. The subject-matter of the invention is to neutralise (saturate) the elementary charge asymmetry by means of an external electrical field. The higher the electrical field strength applied to the flame to be influenced is selected to be, the greater the number of fuel particles which lose their reaction tendency and the weaker the flame becomes. Applications of the idea according to the invention:   - controlling the rate of ignition in Otto-cycle or diesel engines,    - extinguishing fires with liquid, solid or gaseous electrodes,   - protecting combustible materials against ignition, - controlling the flame intensity of furnace burners and keeping the flame away from the wall of the furnace,   - obtaining soot by forced interruption of the reaction. The drawing shows an electrode arrangement for preventing detonation combustion in an Otto-cycle and diesel engine. <IMAGE>

Title: Diaphragm pump with a diaphragm clamped so as to be free of pressure
Inventor: FRITSCH HORST DIPL ING
IPC: F04B43/067
Filed: 1981-12-29
Abstract: In a diaphragm pump the diaphragm separating the pumping chamber from the discharge chamber is clamped, so as to be free of pressure, between the casing body and the pump cover. To this end there is provided, radially outside the diaphragm clamping face, a circumferential pressure equalisation chamber which communicates with the discharge chamber via at least one connecting duct. There is further arranged, radially outside the pressure equalisation chamber and between the pump cover and the casing body, a separate ring seal (ring packing) which seals the pressure equalisation chamber and the discharge chamber externally. As a result, the diaphragm pump is suitable for delivery pressures of far above 350 bar and at the same time permits the use of operationally reliable, highly displacement-effective plastic diaphragms. <IMAGE>

Title: Structural member, in particular for beam constructions, floors, bridges and the like
Inventor: BECKER OTTO ALFRED DR
IPC: E04B2/58
Filed: 1982-01-25
Abstract: Described as exemplary embodiments are bridges, the cantilevered parts of which, in a light type of construction, can be prestressed in an uplifting manner up to the limit of their breaking capacity by prestressing devices arranged, for example, on the banks and having abutments. The prestressing devices are subdivided into individual, separate prestressing chambers for receiving prestressing materials. The ends of supporting prestressing tubes having a plurality of piston-like transverse bodies are passed through the prestressing chambers. The expanding prestressing material is first of all fed into the first chamber and tightens the prestressing tube by its expansion pressure against the transverse piston arranged therein on the prestressing tube. Further prestressing material is then poured into the next separate chamber. By the expansion pressure of the further prestressing material against the next transverse piston arranged there on the extended prestressing tube, the prestressing tube is accordingly additionally tightened, and so on from chamber to chamber. These prestressing forces, which are capable of being increased to an almost unlimited extent, permit cantilevered clear spans of a hitherto unattainable extent and in addition enable the costs of the heavy-load type of construction hitherto necessary to be eliminated. This is of fundamental importance for bridge construction as well as for beam constructions of any kind. For better understanding, reference is made to the attached Figure 3. <IMAGE>

Title: Sea rescue system
Inventor: BLUETHMANN ROLF G H
IPC: B63C9/02
Filed: 1982-06-24
Abstract: The subject matter of the invention is a sea rescue system for saving shipwrecked persons, which consists of active and passive rescue means which are separate from one another and are attached and can be used independently of one another on the sea-going ship and can be lowered at sufficient extension length by means of at least one ship crane or derrick boom. Here, the active rescue means are used to actively assist other crews in distress, and the passive rescue means are used to rescue the ship's company when the ship itself is in distress. The active rescue means advantageously consists of a launch-like lifeboat which is let into a cradle on the deck of the sea-going ship and is lowered into the water by means of a ship crane. The passive rescue means consists of a life raft which is circular in cross-section, is mounted in a bowl adapted to the outer shape of the life raft and fastened to the ship's deck, and can be lowered on either side of the sea-going ship. The life raft has all the essential equipment necessary for the survival of ships' crews and is dimensioned in such a way that the occupants can both lie and stand in it. A specially designed swinging arm enables persons drifting helplessly in the water to be rescued with reasonable expenditure of force in connection with both the active and the passive rescue means.

Patent DE-3230550-A1 (DE)
Title: Gear pump
Inventor: HAUPT FRITZ DIPL ING
IPC: F04C2/18
Filed: 1982-08-17
Abstract: Two meshing gears (24, 26) are mounted in a housing (10) and each of them is assigned a separate motor (40 and 42 respectively). The two motors (40, 42) are flanged to two opposite sides of the housing (10) and connected to the associated gear (24 and 26 respectively) by a respective clutch (36 and 38 respectively). Each of the two gears (24, 26) thus draws the required driving power from the associated motor (40 and 42 respectively); relatively low differential powers, if any, are transmitted between the two gears. The teeth of the gears (24, 26) are thus loaded essentially only by forces and torques caused by the pressure difference between the inlet (12) and the outlet (14) of the gear pump. <IMAGE>

Title: Synchronisation arrangement
Inventor: SANCTIS MASSIMO DE
IPC: H04J3/06
Filed: 1982-08-19
Abstract: The invention relates to a synchronisation device for adapting the bit rates of a digitally coded television signal to a PCM transmission channel having a bit rate of 139.264 = 15 . 10<-4> Mbit/sec with the aid of a synchronous multiplexer. Such an adaptation has previously only been possible with the aid of an elaborate stuffing multiplexer. The solution according to the invention utilises the line frequency of the television signal and derives from this the sampling frequency and the output frequency of the synchronous multiplexer, which is easier to implement, with the aid of PLL circuits with suitable frequency dividers. In spite of the fact that the derived output frequency of the multiplexer slightly deviates in principle from the theoretic PCM transmission frequency, the tolerance range of the latter is met in every case.
