Title: Vehicle hydraulic brake system
IPC: B60T8/46
Filed: 1984-06-02
Abstract: The vehicle brake system (2) comprises a pressure source (3), a brake pressure control valve (4), which can be actuated by means of a pedal (9) by way of a travel simulator (5), an open brake circuit (II) with an antilock valve (18), a master cylinder (13) with a main piston (14), a primary chamber (44), a secondary chamber (45), and an emergency brake plunger (16) aligned counter to the master piston (14), and a brake circuit (I) connected to the secondary chamber (45), which circuit is closed and has two antilock valves (20, 21), an accumulator (22), an accumulator filling valve (23) and a non-return valve (24). The accumulator filling valve (23) is opened by the pressure source (3) as soon as this is switched on, so that the accumulator (22) communicates with the secondary chamber (45) by way of the brake circuit (I). When braking, the accumulator (22) is also filled in addition to the wheel brake cylinders and the master piston (14) covers a greater displacement travel. If, in the event of antilock, the reversing valve (19) connects the primary chamber (44) to a return vessel (17) for the purpose of reducing the brake pressure, the accumulator (22) has the advantage that it shortens the return stroke travel of the master piston (14) so that the necessary brake pressure reduction is not prevented by the emergency braking plunger (16).

Title: Test circuit arrangement for determining the number of turns and the DC resistance of a coil
Inventor: ROECKERT WALTER DIPL ING
IPC: G01R31/72
Filed: 1984-07-31
Abstract: To determine the number of turns and the DC resistance of a coil, it is provided that, at least once for a predetermined period of time during a test process, a magnetic flux changing during this period of time passes through the coil to be tested (PS). This coil is connected to a switch arrangement (S2) which only connects this coil (PS) to a first evaluating device (WME) during the predetermined period of time. This evaluating device determines the number of turns of the coil to be tested by means of the induction voltage occurring across the coil to be tested due to a change in the magnetic flux, and by means of a reference voltage. The switch arrangement (S2) is connected to a second evaluating device (WST) which is connected to the coil to be tested, for determining its DC resistance, whenever the magnetic flux passing through the coil is constant. <IMAGE>
Patent DE-3433710-A1 (DE)
Inventor: LEBLANC JEAN
IPC: F02M59/36
Filed: 1984-09-14
Abstract: The unit fuel injector has a pump piston driven at a constant stroke length, which pumps fuel at injection pressure to an injection nozzle as long as an electrically actuated overflow valve blocks the flow of the fuel flowing from the pump work chamber to a low-pressure chamber via an overflow conduit. The overflow valve is inserted between a first section which communicates continuously with the pump work chamber and a second section leading to the low-pressure chamber of the overflow conduit and is secured to a housing part laterally projecting from the pump housing. The first section of the overflow conduit comprises a connecting bore leading away from the pump work chamber, a control conduit controlled by the overflow valve, and a transverse conduit connecting these two. The transverse conduit extends from the housing side remote from the projecting housing part to the control conduit, crossing through the cylinder bore and in every stroke position of the pump piston is sealed off, without additional sealing means, by the jacket face of the pump piston. The unit fuel injector is particularly suitable for high-pressure injection in Diesel engines.

Title: Apparatus and method for removing gas from cans or similar containers
Inventor: AMELEN FRIEDRICH VON
IPC: G01N1/24
Filed: 1984-10-31
Abstract: An apparatus and a method for removing gas from cans or similar containers, in particular for measuring oxygen in foodstuffs with protective-gas packing, having a movable needle or a suitable puncturing device, are intended to make it possible to eliminate the poor handling of the removal procedures hitherto used; a very small dead volume is to be achieved, the needle is to be easy to operate and the apparatus as a whole is to be simple to operate, with susceptible seals being avoided. For this purpose, it is proposed to surround the needle (70) with a suction cup (74) and to prevent leaks with a seal (61) which forms the boundary of a movement chamber for the needle (70), which chamber is provided with a terminating capillary (77) or the like and sealed up to the rim (75) of the suction cup (74). The needle (70) preferably passes through said suction cup (74) with clearance and is guided in a bore or the like. Moreover, the suction cup (74) is preferably surrounded by a flexible envelope (80) which is placed by means of a seating edge (84) on a container and then makes a vacuum possible around the suction cup (74). The suction cup (74) is placed on the container and a volume is applied to the movement chamber, after which the free needle end is forced out of this evacuated movement chamber into the container and the gas is fed to the analyzer. <IMAGE>
Patent DE-3442331-A1 (DE)
Title: Ink conductor, having a compensating body enclosing it, for writing appliances with ink in a free form and a large ink-storage space
Inventor: WITTE HANS JOACHIM ING GRAD
IPC: B43K7/10
Filed: 1984-11-20
Abstract: For a writing appliance with ink in a free form and a large ink-storage space, emptying the relatively long compensating body without leaving residues is not ensured in every position of the writing appliance as a result of flow resistances in the paths to the ink/air controlled member and high gravitational pressure. The sub-division of the compensating body into two groups of lamellae by means of a non-capillary, radial ventilation duct reduces the flow resistances and the gravitational pressure considerably. At the same time, however, the two groups of lamellae are emptied separately.
Patent DE-3447565-A1 (DE)
Title: Method for driving a direct converter
Inventor: HUSSELS PETER DR ING
IPC: H02M5/27
Filed: 1984-12-21
Abstract: In a method for driving a direct converter which is connected to a multi-phase network, is constructed from partial converters and supplies a three-phase load without any circulating current, with the partial converter being modulated taking into account the zero voltage between the star points of the load and of the partial converters, which are not connected to one another, it is intended to be achieved that only three 3-pulse partial converters (that is to say only 18 converter valves) can be used and that nevertheless the second harmonic in the network current is prevented. This is achieved in that the signal ( alpha 1,  alpha 2,  alpha 3) for modulating each partial converter (21, 22, 23) is initially modified via a characteristic transmitter (2) in such a manner that the modified signal corresponds to the deviation in the amplitude of the second harmonics from that amplitude when the modulation is zero. Each modified signal is multiplied, in a multiplier (31, 32, 33), by the absolute value of the partial converter current (i21, i22, i23). The sum of the product is used, via a regulator (4), as the regulation signal for modulating the individual partial converters. <IMAGE>

Title: Voltage impulse generator
Inventor: RAUPACH FRIEDRICH DR ING
IPC: H02M9/06
Filed: 1985-05-04
Abstract: A voltage impulse generator according to Marx, having at least one switching stage of column-like construction, which contains at least one impulse capacitor, a switching spark gap and the resistors which are required to achieve the desired charging characteristic and impulse waveform is intended to be constructed such that the impulse generator can be produced easily using cheap individual elements, and such that the components which influence the circuit are easily replaceable. Despite this, only a base area which is as small as possible is intended to be required. This is achieved in that the wall (2) of the voltage impulse generator is formed from a plurality of insulating material panels (3), preferably of the same width and predominantly also of the same height, which are connected to one another at or in the region of their vertical end edges (9) by angled or bracket-shaped connecting elements (6), so that, in plan view, the wall (2) forms an equilateral triangle or polygon. <IMAGE>
