Patent DE-4128265-A1 (DE)
Inventor: GERICH ANDREAS
IPC: H04N5/44
Filed: 1991-08-26
Abstract: The invention relates to a method and a device for programme control in television receivers. The invention is based on the fact that television signals which in each case comprise an identification signal designating a particular programme source (for example ARD, ZDF and so forth) are received at the receiving site of a television set. Such an identification signal can be contained, for example, in a colour television signal, particularly in a bi-phase code modulated data block in line 329 of a 625-line standard, or in teletext data which are transmitted jointly with a television signal. According to the invention, possible reflections of the television signal are also taken into consideration in addition to the received field strength during the programme storage, which reflections are detected by means of a comparison of a reference identification signal with the received identification signal. <IMAGE>

Title: Flat bed knitter - has at least one needle bed on swing axis to move out of V=bed layout, for access to machine components
Inventor: SCHIMKO REINHOLD
IPC: D04B7/04
Filed: 1991-09-19
Abstract: The V-bed flatbed knitter has at least one needle bed which can be swung clear of the V-shaped position, round an axis along the needle bed length. The swing axis is parallel to the lower longitudinal edge of the needle bed, and close to it. The swing movement of the needle bed is defined by a slide rail, when moved out of the V-position. The needle bed is mounted by hinges to the machine frame, or it is connected to the frame by a shaft. At least one locking lever holds the needle bed in the open position, in an automatic locking action. A spring is linked to the locking lever at one end and to the machine frame at its other end. The locking lever is moved out of its locked position against the spring. A tolerance free play is between the needle bed and the machine frane near the swing axis. When the needle bed is in the V-position for the V-shaped needle beds, it is held in a defined position by set pins. ADVANTAGE - The structure gives easy access to the knitter components located below the needle beds.

Title: Variable hydrostatic transmission - has adjusting device, to measure pressure drop, by reducing or increasing flow volume to pump/motor
Inventor: BAUSENHART HEINZ
IPC: F16H61/46
Filed: 1991-12-11
Abstract: The variable flow volume is set by an adjusting unit (6), adjusted by a device (8), which becomes active, when the pressure in the low pressure conduit (5a,b) or a feed tube (10) leading to it, drops to below a set level.

Title: Desulphurising bio-gas by selective catalytic oxidn. - followed by washing out the sulphur di:oxide in soda lye, is simple and ecologically compatible
Inventor: HEISEL MICHAEL DR ING
IPC: B01D53/86
Filed: 1991-12-20
Abstract: In this method of desulphurising biogas that contains H2S, the H2S is converted to SO2 by selective catalytic oxidn. and the SO2 in the gas is then washed out in a soda lye wash. Variants are claimed for the oxidation to be done in a reactor in which the biogas is heated, and for a reactor suitable for this purpose. USE/ADVANTAGE - The usual methods of desulphurising biogas involve considerable ecological problems, whereas the simple method here offered, in which the H2S is completely removed from the gas, is compatible with ecological requirementsb

Title: Tongs for lifting and turning building bricks
Inventor: MORARU ERICH W
IPC: B66C1/66
Filed: 1992-12-31
Abstract: Suspended from a scissors mechanism are two coaxially opposed shafts (36) with horizontally projecting fingers (42). To pick up a brick, the gripper fingers are opened using the lever handles (50) and inserted in the brick cavities. The brick is gripped when the handles are released.As the tongs are raised, the weight of the offset brick causes the shafts to rotate and the brick to hang downwards after turning through 90 deg. When the brick is released, the shafts are returned by torsion springs to the pick up position with stops (46) against the cross beam (20).

Title: Temp.-stabilised electronic ignition for IC engine - has series opposition Zener diodes between base of control transistor and earth
Inventor: URUSHIWARA NORIYOSHI
IPC: F02P3/055
Filed: 1993-01-15
Abstract: The primary current in the coil is controlled by a transistorised circuit (2) between the coil connection and earth. The input of the transistor stage has two Zener diodes (3,4) between the input and earth and parallel to the emitter resistance (6) connection to earth. The Zener diodes are in series opposition and have temp. coeffts. similar to the components of the transistor stage. The variation of voltage through the Zener diodes, due to temp. changes, is balanced by the changes in the emitter resistance and the emitter-base voltage. The variation in drive for the coil is reduced to approx 5 per cent as compared with 30 per cent for non-compensated ignition circuits. ADVANTAGE - Improved ignition control, less susceptible to temp. changes.

Title: Method and device for synchronisation of a subscriber station of a network
Inventor: WEIS BERND X DR ING
IPC: H04L7/04
Filed: 1993-02-18
Abstract: A method is described for synchronisation of a subscriber station of a network whose internal signal processing is timed by an internal bit clock, a bit stream (B) comprising a sequence of bit pulses (P1-P5) being fed to the subscriber station, while the bit clock of said bit stream, which is pre-defined by a central clock generator of the network, defines a reference bit clock for the internal signal processing of each subscriber station of the network. According to the invention, it is provided that at least one bit pulse (P1-P5) of the bit stream fed to the subscriber station (1) is oversampled with the N-fold clock frequency of the internal bit clock (CB) of the subscriber station (1), that N sample values produced by this sampling are combined into a sample pattern which is N positions wide, that, in order to detect a clock deviation and/or phase deviation of the internal bit clock (CB) from the reference bit clock, this currently recorded sample pattern is compared with at least one pre-defined reference sample pattern, that, depending on the result of this sample pattern comparison, a synchronisation signal (VS, VS1-VS3; PS) is generated which initiates a correction of this clock deviation and/or phase deviation of the internal bit clock (CB) of the subscriber station (1) from the reference bit clock, and that the aforementioned steps are iteratively repeated until the currently recorded sample pattern and the - at least one - pre-defined reference sample pattern correspond. <IMAGE>

IPC: C02F3/12
Filed: 1993-05-22
Abstract: For the denitrification of sewage, in a two-stage biological purificn. assembly, an additive contg. carbon is fed to the sewage directly before it enters the denitirification basin. The additive is held in a container tank. Pref. the additive, contg. carbon is used as a diluted soln. delivered by a dosing pump from a supply tank into the mixing channel for the sewage.

The alcohol can be ethanol, methanol, butanol or isopropanol. Biochemical prodn. waste water can also be used from the chemical industry, or residue from wine prodn. or mash or must. Any pptd. and flotation sludge is absorbed in the denitrification basin. The matter is recirculated in the dentification basin by an immersed stirrer and the basin is aerated. After denitrification, the matter is finished in a basin with further aeration. The sewage is settled before denitrification. Any phosphate pptn. is initially after denitrification. USE/ADVANTAGE - The technique is for the removal of nitrogen cpds. from the sewage, by nitrate reduction through bacteria to release the nitrogen. The system can be installed in existing plant, with reduced labour for its operation and without increasing the plant size, for a cost-effective action.

Filed: 1993-07-15
Abstract: A table type, mitre box cross-cut saw has a stationary frame (2) at the top of which a table top (3) may be swivelled around a horizontal axis (16) and locked in its horizontal positions. The table top (3) carries a saw unit (7) with an electric motor and a circular saw blade (11) driven by the electric motor. The saw unit (7) may be swivelled, tilted and locked with respect to the table top (3) around a multiaxis hinge (6). A turntable (8) is embedded in the table top (3). A saw opening (28) arranged next to the turntable (8) allows the saw to drive to a maximum extent in any selected mitre cut adjustment, precluding all collisions between the table top (3) and the saw blade (11). The cross-cut area is thus independent from the setting of the mitre cutting angle.
