Patent DE-4009042-A1 (DE)
Inventor: SCHWEISS PETER
IPC: B01D17/035
Filed: 1990-03-21
Abstract: The apparatus for separation of air from fibre suspensions from flotation devices, which fibre suspensions have high levels of air and foam or are a mixture of liquid and foam, is provided with a hydrocyclone (1), the inlet port (4) of which is disposed at least 2.5 m beneath the outlet port of the flotation device for the air-charged liquid or mixture. The separating region (3) of the hydrocyclone is a slender, truncated cone-shaped body, at the pointed (thin) end of which the deaerated liquid is withdrawn. For this purpose, a counterpressure is maintained at this outlet port, so that the inlet port is not completely covered by the liquid eddy, so that sufficient free entry area still remains for the foam. A mechanical foam destroyer with a rotor (10), which is provided with a wheel, is disposed above the entry area (2) of the hydrocyclone, which wheel is furnished with radial blading. A funnel-shaped suction nozzle feeds the air-foam mixture to the wheel.

Title: Welding current control
Inventor: KLEBL WOLFRAM
IPC: B23K26/262
Filed: 1990-05-04
Abstract: To control the welding current, according to the weld speed when welding a continuous seam to form curved plate material into tubes and pipes, a voltage value related to speed is added to an adjustable fixed voltage value.  The adjustable fixed value supply is in series with the tachogenerator, and their outputs are separately connected to the inputs of of an adding amplifier. The amplifier output acts on the regulator which has an output linked to the DC transformer. A voltage divider is between the output of the tachogenerator and the input of the adding amplifier. The power output of the welding laser is adjusted through a regulator which, at its input has, in series, a tachogenerator related to welding speed and an adjustable fixed voltage supply.

Title: Controlling large rotating masses - by common input signal to drive and braking systems
Inventor: KURZ RALF DR ING
IPC: D07B7/06
Filed: 1991-01-23
Abstract: To control large rotating masses which can be braked, such as cable twister cages, the actual position and rotary speed values are compared with the nominal values through position and speed transmitters and a nominal value generator. The output signal from a rotary speed control (12), for the twisting cage (2), at the same time, gives the common input signal (13) for the twister (2) drive which is composed of a current rectifier (21), motor (22), gearing (23) together with the braking assembly with a control valve system (31), brake cylinder (32) and brake pads (33). The input signal (13) for the drive passes through an adaptor (14) and limit (15) as a control signal (16) to a difference valve calculator (17) to show the deviation using the actual current value (18) from a transmitter (18). The control signal passes through a current regulator (20) to the drive. For the braking syustem, the pressure control signals (26) from the adaptor (24) and limit (25) is passed through a pressure regulator (30) to the braking system, after a difference value has been formed (28) together with the supplied (29) actual pressure value (28). ADVANTAGE - The system brings the mechanism to a stop in the shortest possible time in the event of a wire strand break or other episode which requires a stoppage.

Title: Spinning frame - has means of interrupting roving delivery when drafting stops
Inventor: STAHLECKER FRITZ
IPC: D01H13/18
Filed: 1991-03-20
Abstract: On spinning frames having a series of units to produce yarn from rovings, a top roller lifts the roving out of the card can, so that it can be directed to the unit. The top roller has equipment fitted to interrupt delivery as necessary. Pref. the card cans for each unit are mounted on a driven revolving plate (8) which can be disengaged, at the same time as the roving feed is interrupted. The lift from the card can (A) of the roving (4), is through a roller pair (20,21), which is driven as a shaft along the length of the frame, and just above the card cans. A funnel guide (25) is also provided. By means of a connector (26) the drive on the roller pair (20,21) and guide (25) can be lifted at the same time as the drive (8) to the plate to revolve the card can (5) is released. A spring return is fitted, and a catch (27) holds the connector down (L) and thus out of action, until the spinning can recommence. Other designs are proposed for the purpose of braking the individual feed to a unit. ADVANTAGE - In the event of interruption of drafting, as when yarn breakds, the flow of rovings is also stopped.
