Patent DE-1920474-A1 (DE)
Title: Mixer for solids
Inventor: HUEBERS ERNST
IPC: B01F11/00
Filed: 1969-04-23
Abstract: DT 1902200 refers to a closed container having a motion relative to a fixed internal body, thereby producing a mixing effect on contained solids. The addition relates to a container such as a cylindrical tube mounted and rotating eccentrically in the axial direction relative to a fixed internal shaft. Materials to be mixed are fed in at the top of the equipment passing into the annular space, and are mixed by the action of the eccentric tube and the fixed shaft. The advantage is in the construction and also to the ability to control fixed rate of material to the mixer, so that it can be used continuously.

Title: Three-motor drive for audio and video tape recorders - has two collectorless winding D.C. motors with common commutation with state dependent switch
Inventor: REESE PETER
IPC: G11B15/46
Filed: 1973-06-09
Abstract: Two motors are used for driving the winding equipment and a third one for driving the tape, itself. This is attained by use of a switch which supplies the driving motor only and causes the other to be off load and driven by the tape, which also serves as a brake, either mechanically or electrically. Both motors carry an external circular magnet and by application of a 100 kHz signal, one motor or the other is energized. The switch responds to the operating state and direction of drive of the tape, to activate the common commutator drive for the two winding motors.

Title: Two-wire audio frequency line testing - involves disconnection at main distribution frame which allows dialling selector interposition
Inventor: POLZIN ULRICH
IPC: H04Q1/448
Filed: 1973-07-26
Abstract: The method checks the dialling of telephone lines not connected to the coupling network of a central exchange with the dialling selector converter branched for multifrequency operation. The converter transmits dialling impulses with an audio frequency using a controlled delay line VZ1/VZ2 which determines the mark and space separation of the signal. This is followed by dialling of the subscriber's number stored in the central exchange for testing the line between two points while the extension is tested between two further points. Pick-up relays control the encoding of the dialling signal from the exchange.

Abstract: The distributor has a stator ring and a permanent magnet attached to the stator plate by the bolt which screws into the tapped hole in the stator plate. The hole in the stator ring is threaded but provides a clearance hole for the bolt. There is a plain clearance hole in the permanent magnet for the larger bolt which is used to separate the permanent magnet from the stator plate by screwing it into the tapped hole until it touches the surface of the stator plate but is too large to enter the tapped hole. Further screwing of the bolt separates the two parts.

Title: Driving mechanism for crystal-pulling rod - using two magnetic clutches for fast and slow speeds
Inventor: SCHMIDT JOACHIM
IPC: C30B15/30
Filed: 1973-12-18
Abstract: The device consists of a crystal-pulling rod and two separate motor drives. The slow speed axial motion of the rod is obtd. using one motor to rotate a threaded spindle via a worm and worm-wheel, the pulling rod being located in the threaded bush which is prevented from rotating by an electromagnetic coupling (I). The pulling rod is also rotated using the second motor and a pair of gears. When rapid axial movement of the pulling rod is required, coupling (I) is switched off and a second electromagnetic coupling used to link the rod to the gear-drive on the second motor, i.e. the two coupling are used alternately to obtain slow or fast rod motion. Only two driving motors are required and no inter. gear trains is needed.
