Title: Lot-drawing instrument
IPC: G06F7/58
Filed: 1985-05-06
Abstract: Portable technical device for every-day use as an aid for making decisions by random selection, in that the strength of tendencies to aperiodic group formations in the background noise of physical random micro-events is calculated and is signalled as a result, there being the possibility of varying the sequences of the random micro-events. The location for the random events can be any matter. The advance achieved is that imponderable information hidden in the interference level of the background noise can be utilised, in interaction with the user's person, for the lot-drawing operation.
Patent DE-3528641-A1 (DE)
Title: High-voltage DC voltage source
Inventor: LANG ERNST DIPL ING
IPC: H02M7/06
Filed: 1985-08-09
Abstract: A high-voltage DC voltage source has a battery (1) of high-voltage capacitors (C1...Cn) and a charging circuit (2) for charging them. In the case of this high-voltage DC voltage source, it is intended to prevent dielectric overloading of the high-voltage capacitors, in a simple and cost-effective manner. This is achieved in that a monitoring unit (6) is connected in parallel with at least one of the high-voltage capacitors (C1...Cn), which monitoring unit (6), after a predetermined limiting value of the charging voltage has been exceeded, emits a signal to a control device of the charging circuit (2), which control device prevents further charging of the battery (1). <IMAGE>

Title: Driver's cab for lorries of the cab-over-engine configuration
Inventor: DOLENC ANTON DIPL ING
IPC: B62D33/06
Filed: 1985-09-27
Abstract: In the case of a driver's cab for lorries of the cab-over-engine configuration it was previously customary to arrange the engine's air-induction line which leads from an inlet opening over the roof of the driver's cab rearwards to the air filter, in the region of the rear wall of the driver's cab. In order to make it possible to appropriately lengthen the loading area or the lorry body without increasing the noise level in the driver's cab, it is proposed to equip the rear wall (2) of the driver's cab or the rear part of a side wall of the driver's cab with a shaft-shaped niche (3) for receiving the air-induction line (6) and optionally the exhaust pipe.   <IMAGE>

Patent DE-3544109-A1 (DE)
Title: Cap closure for medical vessels
Inventor: SCHNABEL ENGELBERT MATHIAS
IPC: B65D51/00
Filed: 1985-12-13
Abstract: The front side (17) of the plastic cap (13) comprises a chimney (22) the upper end of which merges into the break-out part (27) connected to the handle part (28) via the weakening zone (26). Due to the fact that the weakening zone (26) is not located in the plane of the front wall (17), it is not subject to any great stresses during contraction processes. This avoids the danger of hair crack formation at the weakening zone (26) which would result in contamination of the cap interior. <IMAGE>
Patent DE-3601745-A1 (DE)
Title: Wind power station
Inventor: MICKENHAGEN ERNST DR
IPC: F03D5/00
Filed: 1986-01-22
Abstract: Rotors which were built on ships in order instead of sails to utilise the wind have become known under the name of Flettner rotors. The advantage of these is their slight extent in comparison with a tackle which produces the same amount of energy. Furthermore, there is no need for difficult, manual operation, and both the direction of rotation and the direction of rotation of the rotors can be controlled by motors. A further advantage resides not only in the utilisation of winds which do not blow on at the optimum angle, but also in that the rotors are not endangered by storms. These advantages permit energy to be drawn from the wind by means of a long and stationary track installation on which the rotors circulate as in the case of a cable car. The track installation is set up transverse to the strongest and most frequent winds. It is also possible to use the head (contrary) wind by reversing the direction of rotation. The rotors can be driven by motors which circulate together with them on a carriage, or by friction wheels which roll on the track installation. The present additional application provides for carriages which are not moved on wheels but are raised by magnets.

Title: Subscriber circuit for a domestic telephone system
Inventor: DANIEL WOLFGANG
IPC: H04M19/02
Filed: 1986-05-16
Abstract: Subscriber circuits for a domestic telephone system do not need to perform all the tasks defined by the so-called BORSCHT functions. The AC ringing current, DC feed current and audible tones are often supplied asymmetrically, and detection and evaluation means are provided in the subscriber circuit to identify loop closure. To reduce circuit cost, a voltage regulator with a pulsed load resistor is provided in the subscriber circuit to supply the DC feed current and audible tones and to identify loop closure, and the AC ringing current is supplied by means of a TRIAC. The loop signal is fed to a control device and a ringing disablement device and evaluated in the control device for ringing disablement. Automatic ringing disablement when the handset is taken off-hook in the subscriber device is achieved by combining the loop signal and the ringing enablement signal in the ringing disablement device.
Patent DE-3620424-A1 (DE)
Title: Hybrid coder
Inventor: SPEIDEL JOACHIM DR ING
IPC: H04N7/26
Filed: 1986-06-18
Abstract: In the hybrid coder for video signals described, the data of a video frame are subdivided into equally large data blocks and each newly entered data block is compared with a data block of the preceding video frame by means of a subtractor. The data blocks of the preceding video frame are stored in a frame buffer. To keep the transmission bit rates as low as possible, the data blocks are usually subjected to a transformation (e.g. a Fourier transformation) followed by quantisation. The required great reduction in bit rate necessitates coarse quantisation which results in high quantisation noise. To eliminate the quantisation noise, a low-pass filtering is carried out block by block. The quantiser can then be finer or even be eliminated altogether. The low-pass filtering requires corresponding filtering in a feedback branch of the hybrid coder. The consequence of low-pass filtering is an unsharp video frame from which, however, the disturbances of the quantisation noise which distorts the image in sections are removed.

Title: Fuel feed device
Inventor: OETTING HERMANN DR
IPC: F02D41/00
Filed: 1986-06-20
Abstract: A fuel feed device for a mixture-compressing, multicylinder internal combustion engine is described, which has a control device (7) and in which the quantities of fuel, metered as a function of variables characterising the operating state of the internal combustion engine, can be corrected by signals from a metering device (6) arranged in the exhaust pipe (5) of the internal combustion engine (1) so as to obtain a predetermined air-fuel ratio. In order to ensure that the air-fuel ratio in all cylinders of the internal combustion engine can be kept to a predetermined value, in order to guarantee a constant combustion, irrespective of any influences on the intake system and the like, it is proposed that the metering device (6) be designed for the output of measuring signals individually assigned to the separate cylinders of the internal combustion engine (1). It is further proposed that the control device (7) be designed for the output of control signals which act upon the fuel feed device for feeding quantities of fuel, individually assigned to the separate cylinders of the internal combustion engine and separately achieving the predetermined air-fuel ratio in the individual cylinders. <IMAGE>

Title: XY recorder with a transport apparatus
Inventor: KELLNER JOHANN
IPC: B43L13/02
Filed: 1986-07-24
Abstract: Known XY recorders have the disadvantage that either they have no transport apparatus at all for the recording strip, so that this has to be inserted and removed again manually, or the transport apparatus is of a very expensive design and so considerably increases the cost of the recorder. The object of the invention is, in an XY recorder equipped with at least one servo system, at least to eliminate the drive motor for the transport apparatus and hence to make this a much simpler design. This object is achieved in that the drive of the transport apparatus is provided by those servo elements which guide the writing element (6) during the recording operation. <IMAGE>
