Title: Floatable oil retaining bags - for shipwrecked oil tankers stored empty and filled with oil from leaking tanks
Inventor: PROETZIG REINHARD
IPC: B63B27/24
Filed: 1979-04-24
Abstract: Size of oil slicks, produced by shipwrecked oil tankers, is reduced if an adequate number of large-dia. bags is stored on deck in a rolled-up condition. Each bag has a filling tube alongside and can receive the oil from any leaking ship's tank by a pump. The full bags are thrown overboard and held by lines to the ship. Inflatable floats are preferably also attached to the bags. This enables a captain to apply self help before other ships have come to his aid. The system operates satisfactorily even in heavy seas if the bags are jettisoned on the leeward side.

Title: Composite grinding tool for simultaneous rough and fine machining - with fine grinding section comprising abrasive grains in a flexible textile matrix (BR 13.1.81)
IPC: B24D7/14
Filed: 1979-08-04
Abstract: A composite grinding tool for metal machining comprises a rough grinding section of abrasive grains bonded in a hard matrix connected to a fine grinding section comprising abrasive grains bonded in an open structure textile matrix which is more flexible than the hard matrix. The relative movement of the tool and workpiece is such that the workpiece initially contacts the rough grinding section. The strength of the fine section relative to the rough section is such that with the workpiece contacting the whole grinding area, the proportion of the total grinding pressure absorbed in the fine section corresponds to the proportion of its contact surface with the workpiece. The textile matrix may be a fibre mat or felt with a foamed plastics. Tool may be used in grinding knife blades. Simultaneous rough and fine grinding is effected without burning.

Title: Overvoltage protection circuit for thyristors in frequency converter - has dual-primary transformer to reduce restrictions on thyristor turn-off volts
Inventor: WATERMANN GREGOR
IPC: H02H7/12
Filed: 1979-08-18
Abstract: The protection circuit has a transformer (10) with two separate identical primary windings (W1,W2) each in series with one of two thyristors (21,22) and an oppositely-poled diode (11,12) in a return supply path (Z1,Z2). The secondary winding (W3) of the transformer is connected to a full wave bridge rectifier (13). The dc output of the bridge is connected to the ends of the primary windings. The turns ratio of the windings (W1,W2,W3) is 1:1:2. The windings are tightly coupled. The advantage lies in not having to choose the turn-off voltages of the thyristors and diodes specially -- i.e. sufficient protection is provided without taking this measure.

Title: Connection of data link between PABX and main exchange - using modem automatically connected by dialling correct number
Inventor: BARTHOLOMAE HENRIK ING GRAD
IPC: B29C39/00
Filed: 1979-11-08
Abstract: The principle application of the data link is to enable a main telephone exchange to check the functioning, alter functions, or receive information from, a p.a.b.x. In the p.b.x. installation (NST) an internal line is connected through a special subscriber unit (TSP) to the number selection network. This unit has a change over-switch (U) to select a modem (MP) instead of a handset (T). When the main exchange (VZ) dials the appropriate code number the receiving and processing equipment (AUe,WAS, ZST) in the branch selects the dedicated extension, and switches over the call to the modem. The central exchange is then in direct contact with the branch processor (ZST), and can carry out the required data exchange. The equipment can also be adapted to set up a data link with another subscriber by direct dialling via the public telephone network.

Title: Reversing film drive for editor - has two clutches with direction-controlled drag preventing formation of film loops from inertia
Inventor: OSTERMEIER HEINRICH ING GRAD
IPC: G03B21/43
Filed: 1980-09-12
Abstract: A single drive shaft links the sprocket wheel to the motor driven wheel and to the two clutches for the two belt drives to the film spools. A clutch plate between the two clutches moves axially to either clutch, depending on the direction of the drive shaft, for coupling to either spool drive. No additional gearing is required, only a reversing control for the single motor. The clutch plate is held in a central position between the two clutches by two springs. As the plate pushes against one clutch the friction drag with the other clutch drops to a min. This provides a limited drag for the supply reel and prevents it from over-running when the editor is switched off and causing film loops.

Title: Fuel injection system of IC engine - has regulation for max. efficiency and parallel branch in supply pipe linking chambers of valve and servo control
Inventor: KERCHER WALTER DIPL ING
IPC: F02M69/38
Filed: 1980-10-02
Abstract: The fuel injection system for an internal combustion engine with continuous suction in the suction pipe. The supply of fuel is switched off when the vehicle is running downhill and the air-fuel mixture is only slightly enriched during the heating up phase and during idling or running at constant speed. The air-fuel mixture is enriched when the vehicle is accelerated. The fuel pipe (21) contains a parallel branch (22) which links the lower chambers (7,8) and the upper chambers (5,6) of the differential pressure valves (3,4). The bypass valve starts upstream of the choke. The cross-section of the bypass valve is closed by a regulator controlled by a servo system when the vehicle is travelling downhill. The upper chambers will therefore be shut off w.r.t the lower chambers.

Title: Arrangement for controlling the air/fuel ratio of an internal combustion engine
Inventor: OHARA YOSHIAKI
IPC: F02M7/24
Filed: 1981-01-27
Abstract: An arrangement for controlling the air/fuel ratio for a carburettor of an internal combustion engine contains an intake channel, a choker valve, an exhaust gas channel, a detector as well as an oxygen sensor for determining the concentration of oxygen in the exhaust gases, an air/fuel mixture feed device, an opening and closing electromagnetic valve for correcting the air/fuel ratio of the air/fuel mixture which is fed through the air/fuel mixture feed device and an electronic control circuit. The electronic control circuit contains an evaluation circuit for comparing the output signal of the detector with a stoichiometric value, an integrator circuit connected to the evaluator circuit, a triangular wave pulse generator and a driver circuit for generating square wave pulses for driving the opening and closing electromagnetic valve device for output signals of the integrator circuit and of the triangular wave pulse generator for setting the air/fuel ratio to a value approximately equal to the stoichiometric air/fuel ratio. A circuit for generating a constant signal is optionally actively connected to the electronic control circuit. An engine operation detector for determining a wide open state of the choker valve generates a signal during the wide open state. A circuit actively connects the constant signal generation circuit to the electronic control circuit in order to generate a fixed working cycle of the valve and does not allow the electronic control device to respond to the output signal of the exhaust gas detector. The circuit is constructed in such a way that it is actuated by the signal of the engine operation detector. A delay circuit delays the operation of the circuit. The opening and closing electromagnetic valve is thus actuated with a fixed working cycle after the wide open state lasts a predetermined period. <IMAGE>

Title: Method for fixing the limit values for identifying coins which are good or bad
Inventor: SCHOENE SIEGFRIED
IPC: G07D5/00
Filed: 1981-01-27
Abstract: Known methods for checking coins for their authenticity are based on sensors detecting various characteristics of the coins which serve for identifying the coin as being good or bad. The sensor values and tolerance limits assigned to them are entered permanently in a storage circuit, starting from an "ideal coin" as "desired values". In contrast to this, by means of the present invention, the desired values of the characteristics of the coins to be checked are not entered into a corresponding circuit from the outset, starting from a standard coin, but the circuit determines the tolerance limits as it were itself, in that each desired value is coordinated with the possible actual coin properties occurring in the trade, here the actual value of a random coin selection, and the tolerance possibilities assigned to it are determined. For this purpose, the measured values obtained from the sensors as a result of the coin selection are prepared in digitised form, for example entered in an RAM memory.

Title: Sawtooth generator
Inventor: BRAJDER ANTONIO DIPL ING
IPC: H03K4/56
Filed: 1981-03-30
Abstract: The invention relates to a sawtooth generator having an integrator (1), containing a chargeable capacitor (1b), and having an electronic switch (2), which is connected in parallel with the capacitor (1b), for resetting the integrator (1) at periodic time intervals. The output of the integrator (1) and a first reference voltage source (Ref 1) with opposite polarity are in each case connected to the inputs of an adding element (4). The output of the adding element (4) is connected to the input of a controller (3) with integrator characteristic. The output of the controller (3) is connected to the input of the integrator (1). The time constant of the controller (3) is much greater than the time constant of the integrator (1). In this circuit arrangement, the crest value of the sawtooth voltage becomes independent of its frequency and of capacitance fluctuations of the capacitor (1b) since the controller (3) controls the input voltage of the integrator (1) in such a manner that the crest value of the sawtooth voltage remains constant. <IMAGE>
Patent DE-3113322-A1 (DE)
Title: Large-area emitter
Inventor: RAHN ERHARD
IPC: F21W131/10
Filed: 1981-03-30
Abstract: In a known large-area emitter for high-pressure discharge lamps, the opening is located with the sealing cover on the topside of the box-like reflector housing, which is open on one side. This arrangement has disadvantages for the insertion or replacement of the lamp and for accessibility when mounting the lamp on a high mast. The invention provides identically designed openings in both longitudinal side walls of the reflector housing, and corresponding cutouts in the reflector itself, it being the case that the sealing cover with the lamp holder mounted on the inside and a starter housing mounted on the outside is inserted into one opening and an operating cover is inserted into the other opening. Given openings which are kept small, the result is advantages in the insertion and replacement of the lamp and in accessibility. There is also the possibility of optionally inserting the sealing cover, with the lamp holder and starter housing on either of the two housing sides.
