Patent DE-3731469-A1 (DE)
Title: Electric-motor control drive
Inventor: GRIEB HERBERT DIPL ING
IPC: H02P27/02
Filed: 1987-09-18
Abstract: A control drive having an asynchronous motor with a soft torque/speed characteristic is regulated at discrete constant rotation speeds using a phase-gating controller. The phase-gating angle is a measure of the emitted torque. The torque can be limited and/or the motor MO cut off if a limit value is exceeded, by specifying limit values for the phase-gating angle. The invention is used for control drives. <IMAGE>

Title: Vibration-damping devices
Inventor: MIZUNO KEIICHIRO
IPC: B60G13/00
Filed: 1987-12-08
Abstract: Vibration-damping device, in which a first constructional part (1) is connected via a spring device (3) to a second constructional part in a state in which constructional parts are movable relative to one another, characterised in that there are arranged on one of these two constructional parts (1, 2) a north pole (4) and a south pole (5) which are located opposite one another at a predetermined distance (B) and which form between them a magnetic field, and the remaining constructional part (2, 1) is provided with a plate-like conductive part (8) which extends in the magnetic field. Vibration-damping devices of this type have a damping capacity which depends on the intensity of the vibrations and, moreover, have an improved durability. They can be used for suspension systems for precision machines. <IMAGE>
Patent DE-3803751-A1 (DE)
Title: Optoelectronic stop motion
Inventor: SCHOELLER EUGEN
IPC: B65H63/032
Filed: 1988-02-08
Abstract: The invention relates to a optoelectronic stop motion for contact-free monitoring of the presence of an, in particular, stationary thread in textile machines with the aid of a light barrier. The light barrier comprises a plurality of transmitting diodes arranged parallel which illuminate a common light-receiver. The diodes are alternately and continuously driven, in each case only one diode being switched on. The luminous fluxes of the transmitting diodes generate the same signal in the receiver when the light barrier is undisturbed. If, however, a thread is located within the light barrier, the luminous flux of that transmitting diode, inside the luminous cone of which the thread is located, is attenuated. This leads to an attenuation of the signal arising in the receiver. This attenuation is a criteria for the presence of a thread within the light barrier.

Patent DE-3821515-A1 (DE)
Title: Programmable gate arrangement
Inventor: SCHECK WERNER DR
IPC: H03K19/177
Filed: 1988-06-25
Abstract: A memory matrix of a logical gate arrangement contains a number of independent data sets, each of which defines a logical function of the gate arrangement. Each data set can be activated for dynamic configuration of the gate arrangement by selecting its address. To change the function, the transfer of the memory contents to the traditional two-dimensional matrix is omitted, since only the address of the corresponding memory plane must be passed over. The gate arrangement can be used instead of microprocessors, to achieve much faster program running.
Patent DE-3822860-A1 (DE)
Title: Plastic wide-neck drum
Inventor: BRUNE HERMANN
IPC: B65D43/02
Filed: 1988-07-06
Abstract: A plastic wide-neck drum, produced by blow-moulding, with a clamping ring lid closure and with a blow-moulded flange ring extending radially outwards. The flange ring is blown out of the preform introduced into the blow mould. The transition from the flange ring to the drum body is formed as an annular groove which transmits a spring function to the flange ring. Adaptation of the flange ring in the course of closure of the drum is thus possible and restoration after opening the drum is secured, such that pressurisation of the inserted seal is guaranteed with every closing operation. Likewise for reasons of adaptation and flexibility of the lid, the lid flange is segmented on the circumference.

Title: Device for the continuous determination of the mass of a fibre sliver by means of two rollers pressable against one another
Inventor: RICHTER GUENTER
IPC: D01H13/32
Filed: 1988-08-08
Abstract: In a known device, when the rollers are pressed against one another a sag occurs on the fixed roller, and this sag influences the measurement and leads to measuring errors resulting in incorrect regulations and concomitant quality defects in the sliver supplied. In order to eliminate the influences of sagging, special measures involving a high outlay are necessary. In a new device, the sag occurring in the fixed roller is not to influence the measurement and, at the same time, good adjustability is to be provided. The sensing member (5) is arranged on the movable roller (3), and the sensing surface (8) is opposite one of the circumferential surfaces (9) of the fixed roller (2) and essentially outside the plane (12) containing the axes (10, 11) of the two rollers (2, 3). The continuous determination of the mass of a fibre sliver by means of two rollers pressable against one another. <IMAGE>

Title: Deflection-type absorber
Inventor: EIPPER KONRAD DIPL ING
IPC: B60R19/32
Filed: 1988-10-28
Abstract: A deflection-type absorber for the fastening, in a yielding fashion, of a bumper to the frame side member of a vehicle body has a regenerating hydraulic, gas or solid shock absorber and a non-regenerating deformation element, which is arranged downstream of the latter, to take up energy. The deformation element and the operating cylinder of the shock absorber are arranged in a casing which is fastened to the frame side member. In order to allow the deflection-type absorber to be of simple design and be easy to disassemble, the casing takes the form of a guiding container which tightly encloses the operating cylinder and the deformation element takes the form of an energy absorber which fills the guiding container, while resting against the container floor, in the container section situated immediately in front of the container floor. To enable to deflection-type absorber to be fastened, there is fixedly connected to the guiding container a coaxially fastening plate in the vicinity of the edge of the container, the dimensions of the said fastening plate being such that it is supported by the end face of the hollow frame side member.

Title: Device for cleaning the exhaust gases from diesel engines
Inventor: MAYER ANDREAS DIPL ING
IPC: B01D53/94
Filed: 1989-03-11
Abstract: In a device for cleaning the exhaust gases from diesel engines, a filter element (1) is arranged in the cross-section of a housing (3) through which the exhaust gas (2) flows. Its filter zone (1a) at the front in the incoming-flow direction is coated with a catalyst to reduce the ignition temperature of the soot particles. The other filter zone (1b), arranged downstream of the front filter zone (1a), is coated with a catalyst to postoxidise the gaseous pollutants. A continuous regeneration at low ignition temperature is thus guaranteed and at the same time it is ensured that the combustion can spread unhindered through the entire filter element (1), and likewise that the soot particles deposited in the filter zone (1b) are also burnt straight away. <IMAGE>

Title: Sewing machine for joining two layers with different elongation - using two computers to calculate cross- and auto-correlation functions
Inventor: ARNOLD KURT DR
IPC: D05B35/10
Filed: 1990-01-11
Abstract: A sewing machine for sewing together to  equal length two layers of material with different elongation has two cameras to take partly overlapping pictures of each layer for temporary digitised storage. The correlation max. is determined by calculating the cross-correlation function of the overlapping picture signals. The actual  elongation of each layer is determined by calculating the auto-correlation function. If neither the warp nor the weft threads run parallel to the  direction of advance, their angle is first determined. A comparison of the advance parameters and of the elongations for both layers yields a control signal for the stitch positioner. ADVANTAGE - This sews together two layers of material with the same number of meshes or threads per unit length.
