Patent DE-3322965-A1 (DE)
Title: Drilling machine
Inventor: BERGLER OTTO
IPC: B23B45/16
Filed: 1983-06-25
Abstract: A drilling machine, in particular a hammer drill, is provided with an engageable and disengageable percussion mechanism. The change-over switch for this percussion mechanism is arranged on a housing surface opposite a handle. This makes it possible to engage or disengage the percussion mechanism without removing the hand from the handle. The drilling operation therefore need not be interrupted. In an advantageous development, the percussion-mechanism change-over switch consists of a pivoted lever which is connected via a bearing to a shaft and the radial movement of which is converted via an abutting surface into an axial movement of the shaft. The shaft is under the pretension of a spring and is connected to a pinion. The pinion carries claws which can be brought into engagement with corresponding claws of a wobble bearing which brings about the reciprocating movement of an energising piston and thus of the percussion mechanism. The percussion mechanism can therefore be engaged by engaging the claw clutch.
Patent DE-3326729-A1 (DE)
Inventor: URSTOEGER RUPERT
IPC: H01M10/44
Filed: 1983-07-25
Abstract: In an electrochemical storage device such as a zinc-bromine or zinc-chlorine accumulator containing groups of electrochemical cells connected in series to a load, nonuniformly distributed deposits of the active electrochemical material on the electrodes are removed by a complete discharge of the cells. While the storage device energizes a principal load, the cell groups of the storage device are discharged in a cyclic sequence via an auxiliary load and disconnected from the series circuit of the cell groups no later than the time at which the respective cell group has attained its operational use limit. The disconnected discharging cell group is further discharged via the auxiliary load until the nonuniformly distributed deposits on the electrodes of the cell group are totally removed. The cell group is then recharged and reinserted into the series circuit of the cell groups or, alternatively, reconnected to the series circuit and then recharged. The method of operation enables the energization of a load by the storage device while the device is being regenerated.

Title: Method and circuit arrangement for controlling planarity in cold-rolling mills
Inventor: HAUSEN MAREK DIPL ING
IPC: B21B1/28
Filed: 1983-08-31
Abstract: The invention concerns methods and circuit arrangements for carrying out the methods for controlling planarity in cold-rolling mills with a roll stand of six or more rolls, wherein the tensile stress distribution (31) across the width of the strip (14) to be rolled is measured and compared with a presettable nominal distribution (33) and, from the deviation between the actual distribution (31) and the nominal distribution (33), a coefficient is formed which serves to adjust the roll deflection. In a measured-value processing device (36), a strip centre coefficient (aM) and a strip edge coefficient (aK) is formed in each case from the deviation of the tensile stress distribution in the strip centre zone (M) and in the strip edge zone (K). The strip centre coefficient (aM) is utilised for controlling the deflection of the intermediate rolls. The strip edge coefficient (aK) is utilised for controlling the working roll deflection. For further decoupling of the control loops for the intermediate roll deflection and working roll deflection, a decoupling device (45) is proposed, by means of which a targeted mutual influencing of the coefficients (aM, aK) is achieved. <IMAGE>

Title: Installation for supplying a three-phase network, using a shaft generator
Inventor: ANGERMAIER PETER DIPL ING
IPC: H02K17/42
Filed: 1984-07-10
Abstract: Installations for supplying a network with constant frequency, using an a synchronous generator which is driven with variable frequency have, inter alia, the defects that a network must be present for starting and, in the event of a fault, an adequate short-circuit current cannot be supplied. For this reason, a synchronous generator (6) is driven by the same shaft as the asynchronous generator (3), which synchronous generator (6) impresses a rotating field on the rotor of the asynchronous generator, the frequency of which rotating field corresponds to the difference between the rotation frequency of the asynchronous generator (3) and the network frequency, and the current of which rotating field is used for setting the terminal voltage of the stator winding of the asynchronous generator (3). <IMAGE>
Patent DE-3426047-A1 (DE)
Title: Code error detection circuit for a digital communications system
Inventor: SEEGER DIETER DIPL ING
IPC: G11B20/14
Filed: 1984-07-14
Abstract: Known digital circuits for detecting code errors in digital communications systems with a limited-disparity block code use the variation of the current digital sum as a criterion. To reduce circuit cost and power consumption compared with circuits of this type, an error detection circuit is described which, in its input circuit (6, 7, 8, 9), derives two pulse strings (S1, S2) from the binary received signal, the difference in their number of pulses providing a measure for the disparity of the binary received signal. The difference in the two numbers of pulses which is permissible according to the coding rules remains within a narrower value range than the current digital sum, so that a substantially simplified counting device can be used to represent the permissible conditions. The evaluation circuit (1, 2, 3) generates an error pulse whenever the difference between the two numbers of pulses exceeds a predefined value. A simple shift register (1) is adequate for this purpose and a simple logic circuit (2) suffices to combine the shift register outputs. Once the error pulse has been transmitted, the error detection circuit is reset to its initial condition, thereby avoiding the known problem of sequential errors. <IMAGE>

Title: Air separator for a metering installation, in particular for collecting milk
Inventor: EISMANN JOSEF DIPL ING
IPC: A01J5/04
Filed: 1984-08-24
Abstract: The air separator according to Figure 1 is equipped with a displacer element which, for the purpose of increasing the switching accuracy, reduces the free cross-section of the air separator such that the permissible fluctuations in level in this area correspond to the differences in volume prescribed by the weights and measures authorities. When they are arranged in a fixed fashion, displacer elements of this type effect an increased flow rate in this area of the air separator, this flow rate preventing, amongst other disadvantages, an air separation in this zone and beyond. The invention provides for the displacer element to be designed as a float which, in the operating state of the air separator, is raised up such that it does not hinder the flow of milk through the air separator and the degassing of the milk. When the metering is finished, the displacer element falls into its lower position and can then carry out the prescribed function of increasing the switching accuracy. <IMAGE>
Patent DE-3432242-A1 (DE)
Title: Large-area magazine retaining buttons
Inventor: SUHR WERNER
IPC: F41A17/38
Filed: 1984-09-01
Abstract: In order to achieve a very high level of safety in the operation and carrying of hand guns, a weapon must be functionally understandable for the carrier and must also be capable of being coped with in stressful situations. The magazine retaining button can easily be identified as the control element for replacing the magazine, as a result of its conspicuous size and colour. It can easily be identified by touch in the dark. Its method of fitment on both sides makes it virtually impossible for the magazine to be lost as a result of the weapon being jarred carelessly. This effect is supported by the position of the magazine retaining buttons inside the handle shells or inside the weapon outline. The magazine can be removed only by pressing both magazine retaining buttons deliberately and simultaneously.
