Patent DE-2116145-B2 (DE)
Title: Sawtooth voltage generator has frequency held constant - using resistive voltage divider to produce references for charging and discharging capacitor
IPC: H03K4/06
Filed: 1971-04-02
Abstract: The sawtooth voltage generator has a voltage controlled current source switched to a capacitor to provide charging and discharging currents, and two reference voltages to enable the upper and lower limits of the sawtooth or triangular wave to be kept within prescribed limits. The output signal has its frequency held constant by using a resistive voltage divider coupled to the supply and providing the voltages (U1, U2, U3) used as references for the charging/discharging switching and controlling the current source. The voltage divider is constructed from integrated resistors (R1-R5) having identical temperature coefficients.

Title: Rotary printing drum hammer release control - differential amplifier with D.C. and saw-tooth voltage inputs determines tripping point
IPC: B41J9/38
Filed: 1971-08-07
Abstract: The d.c. signal voltage is proportional to the speed of the printing drum which exhibits the printing types on its periphery and is derived by a U-shaped pickup. The shanks of the latter are around a signal disc carried by the drum shaft, and the signal of the pickup indicates changes in the drum velocity due to variations in the supply frequency and voltage, as well as owing to fluctuations in temperature or friction effects. As a result, the timing of operating the printing hammer by a solenoid is triggered by the difference between the saw-tooth voltage, independent of the drum speed and the d.c. signal which is a function of the speed.

Title: Horizontal drum washing machine - with axial ribs and parallel radial ribs contg. steam feed
IPC: D06F31/00
Filed: 1972-01-19
Abstract: The clothing is passed along the rotating drum, against the flow of the water, the rib configuration carrying the clothing upwards and then allowing it to fall sharply which causes the required squeezing and kneading effect in the water. Dividing walls provide the separate temp. zones for the clothing to pass through. The purpose is to increase the progressive advance of the clothing through the washing drum.

Title: Vehicle front mounted snowplough - has snow deflector fastened to connecting plate without obstructing driver's vision
IPC: E01H5/06
Filed: 1972-01-13
Abstract: The front-mountable snowplough has a connecting plate, or similar, for attachment to a vehicle which pushes it along, and a snow deflector sited above the top edge of the plough blade. The snow deflector (60) is fixed to the connecting plate (20) and can be fitted with spikes (61) in the fixture area, for firm clamping into sockets (23) attached to the connecting plate. The drivers vision is not seriously impeded by the snow deflector, which in turn assists vision by preventing dry or powdered snow from swirling, esp. in strong winds.

Abstract: A decoding device for code words which are protected against the occurrence of several symbol errors per code word by means of a Reed-Solomon code is provided with a word buffer which comprises a space for the storage of an erasure indication per symbol received. For correction of the code word, first the syndrome symbols are formed by multiplication by the parity check matrix. The sum of twice the number of error symbols and once the number of erasure symbols may not be larger than the number of syndrome symbols. First the syndrome symbols are modified so that the syndrome symbols which could possibly relate to error symbols (non-erasure symbols) are no longer influenced by the erasure symbols. The key equation and error locator equation for the non-influenced syndrome symbols can then be separately solved, so that the locations of error symbols can be found. The latter syndrome symbols are then modified, when necessary, for calculated error locations, while the error values or erasure values are determined from a set of mutually independent syndrome symbols whose numer equals the sum of error symbols and erasure symbols. There is provided an arithmetic unit for the Galois-field which, for the sake of simplicity, performs the calculations on the exponents of the symbols which are written as powers of the basic symbol of the Galois-field.

Abstract: An Optical Transmission System (1) includes a monitor (8) for outputting monitored data (a) representative of the extent to which an optical signal is degraded by polarization mode dispersion. The monitor measures the degree of depolarization (U) present in a sample of the optical signal derived from an optical tap (10), the depolarization being associated with polarization variation at the bit rate frequency of a signal data stream carried by the optical signal. The monitored data is used to control operation of the system to reroute the optical path taken by the optical signal in the event of a threshold level of polarization mode dispersion being exceeded. A transmitter (2) of the optical signal may also be controlled to minimize polarization mode dispersion by varying the polarization state of the optical signal at launch so as to reduce the measured monitored data. The monitor functions during normal transmission of optical signals without the need for shutting down links of the system for measurement purposes. The invention has particular application to long haul optical transmissions of data streams at 10 Gb/sec or more. <IMAGE>

Abstract: A welding sleeve useable for connecting of pipes formed from thermoplastic material, is formed from a tubular body of thermoplastic material and a coil disposed on its inside surface. The coil has a resistance wire encased with thermoplastic material. The windings of the coil (4) are bonded into a compact coil which is inserted into the heated tubular body while it is simultaneously widened. As the result of a partial contraction of the tubular body also of the coil a firm connection develops between the oil and the body. Furthermore, the tubular body has a frozen-in, latent, radial contraction strain as a result of the widening, which during heating during the welding process, eliminates the radial play between coil and the pipes and produces a welding pressure.

Abstract: A bearing housing characterized by novel features of construction and arrangement providing an adjustable bearing seat. The housing has a longitudinal slot and mounting portions protruding at each side of the slot. Each of the mounting portions is provided with a support surface confronting a base which in the unloaded condition is disposed at an angle relative to the base. The angular relationship of the mounting portions to the base can be selectively varied by pressing the mounting portions against the base by fastening elements engaging through openings in the mounting portion and engageable in the base. The housing is elastically deformable and when so adjusted the width of the slot is selectively varied and thereby the diameter of the seat can be adjusted.
