Patent DE-2911866-A1 (DE)
Inventor: LECHNER ROBERT DIPL ING
IPC: H04L25/22
Filed: 1979-03-26
Abstract: A hybrid circuit arrangement for a telecommunication system includes a transformer having a first and a second partial winding connected to a two-wire line. Third and fourth partial windings having a grounded junction are coupled to a receiving branch and a transmitting branch of a four-wire transmission line, respectively. A power supply bridge having a resultant supply resistor and a supply capacitor is inserted between the first two partial windings. The total inductance of these windings equals the supply capacitor value times the squared supply resistor value. An ohmic load resistor terminating the receiving branch has a resistance according to a specific relationship depending on the ratio of turns of the third partial winding divided by those of the first and second partial windings. Finally, there is provided a quadripole network connected by a first input to the fourth partial winding, by a second input to the receiving branch; by a first output to the transmission line, and by a second output to ground. This network composed of a RC-network is designed such that signal portions of a signal received from the receiving branch of the transmission line supplied to the network directly and across the third and fourth partial windings in a phase-shifted condition are superimposed for cancellation.

Title: Double sealing rings for hydraulic actuator - has second ring retaining any fluid leaking past first ring
Inventor: SCHAER FRITZ
IPC: F16C33/76
Filed: 1979-04-05
Abstract: The hydraulic actuator of a material handling device has a double seal fitted to the piston rod (10). Two circumferential grooves (26, 2me are machined in the body (1) of the hydraulic actuator for two sealing rings (22, 23). The bore (28) in the body between these two grooves is slightly enlarged to form an annular connecting channel. As the piston rod oscillates any fluid leaking from the first sealing ring (22) forms a thin film on the rod. This film is then removed by the second ring (23) as the rod passes through it, so that all leakage is eliminated.

Title: Bending webbed plastic tubing - using two bending rollers which have their normal pressure maintained by being mounted on tension device
Inventor: GROENEBAUM THEO ING GRAD
IPC: B29C53/08
Filed: 1979-04-11
Abstract: Plastic rubing, of any section with stiffening ribs, is bent in a machine with a fixed curved block and a pressure device to produce the required radius of curvature by bending the tubing against that block. The latter device has two shaping members which are moved under pressure at right angles to the tubing, their mounting allowing them to move apart proportionally to the applied pressure/fixed block curvature. They are fixed to a tension system however, which oppose their movements apart and keeps them pressing normally against the tubing. No undesirable effects, simple design machine, uniform deformation pressure, partic. suitable for bending e.g. window and door frames.

Title: Filter circuit of individual charge transfer devices - has empty intermediate spaces between charges, representing scanning values of useful signal
Inventor: GOSER KARL DR ING
IPC: H03H15/02
Filed: 1979-07-27
Abstract: The charge transfer devices contain both bucket brigade and charge coupled devices. The charge transfer devices of multi-phase have their clock pulse signal mutually offset such that adjacent transfer capacities operate with phase shifted clock pulses. The filter circuit, containing individual charge transfer elements, has at least one closed loop with unidirectional transfer characteristic. Between the charges, representing individual scanning values of a useful signal are inserted empty intermediate intervals. The accumulating charge is removed from these intervals by a gate circuit (T), controlled by a clock pulse signal (0). The application of the closed loop of charge coupled devices reduces the interference to a lowest possible level, such interference appearing due to blocking currents. Simultaneously the circuit operating point is fixed.

Abstract: Winding gear for a cable drum includes a winding wheel mounted in a cage so that it can travel to and fro along a shaft with a device at one end. This drives a horizontal chain with a chain pinion at each end. The chain carries a projecting pin which fits into a plate with a slot in it. The drive at one end can consist of a chain with guides driven by a wheel on the winding drum, passing round a chain wheel which in turn drives a wheel mounted on the same spindle as the chain pinion for the horizontal chain. A toothed belt or other chain can be alternatively used for the first drive. The cage travels along a smooth shaft.

Title: Sewing machine spool thread tensioner using magnetic induction - controlled by adjusting current supply to exciting field coil
Inventor: HANYU SUSUMU
IPC: D05B63/00
Filed: 1980-01-31
Abstract: Underthread spool made of magnetic material is held in a spool carrier of synthetic resin with a base of magnetic material which is housed in a dish-shaped loop catcher so that a small clearance is maintained between the base of the carrier and the floor of the loop catcher. A magnetic field produced in the loop-catcher shaft by a surrounding field coil induces a complementary field in the spool and the carrier base, which retards rotation of the spool as yarn is withdrawn from it. The current in the field coil can be varied to adjust the tension in the unwinding thread. Tension adjustments can be made simply and rapidly, if necessary whilst the machine is in operation, without the need to dismantle the spool mounting.

Title: Support for suspended files - has two swivel pairs of struts with eccentric swivel axis to prevent accidental collapsing
Inventor: REICH ERNST
IPC: B42F15/00
Filed: 1980-04-16
Abstract: The file support comprises two pairs of struts (2). The struts of each pair are connected at one end by a support rail (3). Each strut is each mounted in one end of two horizontal parallel frame supports (1) so that it can be folded from a horizontal position into an upright useful position and vice versa. When the struts are in the upright position the active plane of the forces which attach the support rails of the struts runs practically through the swivel axis of the struts so that with an upright force action on the support rails force momentum cannot occur at all or scarcely at all so that the stability of the entire support is unimpaired.
