Title: Piston/cylinder unit
Inventor: FLEISCHER-HARKORT ROLF
IPC: F15B15/14
Filed: 1984-07-20
Abstract: The invention relates to a piston/cylinder unit with a main piston and a secondary piston, whose allocated piston rod or allocated piston tube can be led separately out of the cylinder and can carry complementary tools. When pressure medium is admitted to the top side of the cylinder, the secondary piston tends to remain in its maximum extended position, but it is carried along downwards during a clamping action between the piston rod allocated to the main piston and the piston tube, so that a clamping action with subsequent movement can be obtained with a single admission of pressure medium to the cylinder. When pressure medium is admitted in the opposite direction, the movement is reversed, and at the end of this movement the restraint between the piston rod and the piston tube is neutralised again.

Title: Method for determining the presence of a predetermined filling level in a container, and circuit arrangement for carrying out the method
Inventor: CORDT BRUNO
IPC: G01F23/24
Filed: 1984-07-20
Abstract: A method is described with the aid of which the presence of a predetermined filling level in a container (10) can be determined. The determination is performed using an electrically heatable sensor (14), which is arranged at the level of the predetermined filling level in the interior of the container (10) and whose electrical resistance changes with the sensor temperature. In the method, the value of the electrical resistance of the sensor (14) is measured at the start of a measuring cycle and stored as a first measured value. The value of the electrical resistance of the sensor (14) is remeasured at a time interval after the first measurement and stored as a second measured value. The presence of the predetermined filling level is indicated when the difference between the second measured value and the first measured value is smaller than a prescribed limiting difference. The circuit arrangement for carrying out the method contains a converter (22) for generating a number of pulses which corresponds to the measured value fed to it. A counter (28) with complementable counter stages counts the pulses emitted by the converter (22). With the aid of an input device (34) for the counter (28), the latter can be set to a counter content corresponding to the limiting difference. A sequence control circuit (46) triggers the addition of the number of pulses corresponding to the first recorded measured value to the preset counter content, then the ...

Title: Method and arrangement for electronic detonation of anti-tank mines
Inventor: BLAUHUT REINHOLD
IPC: F42C13/00
Filed: 1984-12-12
Abstract: A method for the electronic detonation of anti-tank mines, according to which signals from a seismic sensor and at least one magnetic-field sensor are analysed and lead to a detonator being triggered when they occur simultaneously. The technical problem is to provide a method which keeps the current consumption as low as possible and is additionally insensitive to interference and external influence. Each seismic signal triggers a timebase. During the time base, three magnetic-field sensors for the magnetic-field components in the three spatial axes are activated. The signals from the magnetic-field sensors are in each case investigated for extreme values and field reversal and in each case produce a magnetic-field sensor if response-signal patterns occur. An And linkage of the seismic signal and the three magnetic-field signals is carried out, and the output signal of the And linkage activates a triggering circuit for the detonator. <IMAGE>

Abstract: A chuck for powered hand tools, in particular hammer drills, is proposed which is suitable for the torque-transmitting accommodation both of drilling tools with a four-groove system at a fixed shank diameter and of a three-groove system with variable diameter. Furthermore, the chuck can accommodate drilling tools with a purely cylindrical shank at a variable diameter. For the positive chucking of drilling tools with a three-groove system as well as for the frictional chucking of drilling tools with a purely cylindrical surface, the chuck jaws (26 to 28) are uniformly fed in via the clamping ring (11) and are locked by means of a locking ring (30). To accommodate a tool shank to be chucked positively and having a four-groove system, two of the three chuck jaws are firmly held in their outer position, while the third chuck jaw (26) engages as a positive driving chuck jaw in the driving groove of the drilling tool (46). An additional locking pin (36) serves to axially lock the four-groove drilling tool. <IMAGE>

Title: Method for determining and optimising the optical path length of a continuous transparent layer or of a structured layer
Inventor: KRAUS HEINZ
IPC: G01B11/06
Filed: 1985-05-24
Abstract: The determination and optimisation of the optical path length of a thin layer (1, 8, 12, 14) is performed by irradiating the layer (1, 8, 12, 14) by means of measurement radiation (19, 40) of known wavelength  lambda . Through a defined structuring of the layer (1, 14) or by applying defined structures (6, 7, 9) to the surfaces of a continuous layer (8, 12) which is transparent to the measurement radiation (19, 40) diffraction rays (210, 211, 212 and 410, 411, 412) are formed whose intensities are detected by receivers (220, 221, 222 or 420, 421, 422). By a comparison of the signal amplitudes of the individual receivers (220, 221, 222 and 420, 421, 422) and by a comparison with the intensity of the measurement radiation (19 or 40), the optical path length of the layer (1, 8, 12 or 14) is calculated. This method is to be applied, in particular, in the production of phase gratings, by regulating the precipitation parameters continuously as a function of the measurement result of the method according to the invention (Figure 5). <IMAGE>
