Patent DE-2714536-A1 (DE)
Title: Concrete additive prepd. from fly ash - used as substitute for gravel and aggregate
Inventor: SCHOLZ HANS DR ING
IPC: C04B18/02
Filed: 1977-04-01
Abstract: A concrete additive consists of fly ash to which lime, cement or other binders (alone or mixed) which harden hydraulically may be added. Other inert additives such as sand, stone flour, asbestos wool etc. may also be present. The fly ash is formed into pellets after adding water and fired. According to the amount of combustible material in the fly ash more or less coal dust is added to the mix. Process could consume the entire annual output of fly ash without difficulty, thus contributing to conservation and ecological protection. The product can replace gravel or aggregate in the mfr. of concrete.
Patent DE-2718860-A1 (DE)
Title: Temp. measuring lance for molten metal - has spring loaded head to give signal when in contact with metal surface
Inventor: KOOPMANN HERBERT
IPC: G01K13/12
Filed: 1977-04-28
Abstract: The temperature measuring lance for molten metal, of the main patent, operates when the measuring head makes contact with the surface of the metal. The temperature measuring lance head (2) is supported in the inner tube (7) by a flange (4) resting on the end of a sleeve (5) with a spring (6) supporting part of the weight. When the lance head tip touches the surface of the molten metal, the added resistance of the molten metal enables the spring (5) to push the lance head (2) upwards so that it actuates the sensing device (16). The sensing device (16) transmits a signal to the control mechanism which ensures that the lance head tip is pushed into the molten metal to the correct depth.
Patent DE-2721632-A1 (DE)
Title: Single channel radio direction finder - has fast Fourier transform non-recursive digital filtering and goniometer connected to receiver
Inventor: SCHALLER WOLFGANG DR ING
IPC: G01S3/06
Filed: 1977-05-13
Abstract: The direction finder is single-channel working with a goniometer connected to a receiver. The output signal of the latter is multiplied with a complex carrier whose angular frequency is the same as the angular frequency of rotation of the goniometer. The resulting signals are filtered to remove the sidebands and provide an output signal to drive the display unit. The receiver contains a non-recursive digital filter as the frequency-selective element and which fulfill the filtering function by means of fast Fourier transformation. All signals within the tuning range of the multi-channel receiver are resolved together and the required radio bearings are selected by means of an automatic signal gating unit.

Title: Intermediate regenerator or amplifier fed via cable - has reference diode with two terminals for both anode and cathode for protection against induced voltages and currents
Inventor: SCHEUERMANN HELMUT DIPL ING
IPC: H04B3/44
Filed: 1977-07-06
Abstract: The intermediate amplifier or regenerator has a reference diode and is remotely fed with power over a cable or line. Both the anode (A) and the cathode of the reference diode, e.g. a Zener diode, have two terminals (1, 3; 2, 4). The intermediate regenerator (Z) is connected to one cathode terminal (2) and one anode terminal (4), and remote feeding of the regenerator is effected via the other cathode terminal (1) and the other anode terminal (3). In a practical form one electrode (A) of the reference diode is connected to the centre of a housing, and the two ends of the housing form the two terminals (3, 4) of this electrode. Highly effective protection against induced voltages and currents is afforded for the regenerator without excessive expenditure and without fundamental circuit changes.
Patent DE-2735289-A1 (DE)
Title: Copy changing in stretching and twisting machines - is controlled by tripping and starting signals which trip and start steps sequentially with time delays
Inventor: RELLENSMANN WOLFGANG
IPC: D01H1/32
Filed: 1977-08-05
Abstract: Cop changing is stretching and twisting machines is carried out without breaking off the yarn path by allowing the ring bank on receipt of the 'off' signal to complete its operation and to come to a halt in its lowermost position, simultaneously tripping the stretching stations which come to a halt, whilst the twisting members are tripped after a time delay and are brought to a halt and thereafter the whorls are tripped after a time delay and brought to a halt; and that after the cop change and on receipt of the 'start' signal, the whorl drives are restarted, and the drives for the twisting members and the stretching stations are started successively after a corresp. time delay and thereafter the ring bank is allowed to start its program controlled operation. Cop changing process leads to a time saving of approx. 40 mins. for an operating crew of three persons. In the case of cop wts. of 1.2 kg and spinning bobbins of 7.2 kg, the changing frequency of 5x40 can lead to a time saving of 3 hrs and 20 mins.

Title: Easily programmed and controlled servo drive - has stepping motor, synchronous motor or detent mechanism controlling servomotor for complex movements
IPC: G05B19/40
Filed: 1977-12-15
Abstract: The servo drive mechanism comprises an electric/hydraulic/pneumatic/magnetic or mechanical servo controlled by a stepping motor or synchronous motor via a coupling. The servo-drive is connected to a power supply and the stepping motor is controlled via sequential signals or other data. With this type of control no positional feed-back is required and each movement can be controlled by easily-stored signals in a timed sequence. In the event of overshoot, only the servo-drive overshoots and the positional accuracy, speed and acceleration can be selected as required. The drive system is designed for particularly complex movements.

Patent DE-2758379-A1 (DE)
IPC: H01C10/46
Filed: 1977-12-28
Abstract: In a measured value transmitter designed as a level sensor, a permanent magnet (3) is provided in the potentiometer which is guided along elongated magnetically operable dry-reed switches (34, 43) and which closes the respective opposite-positioned dry-reed switch. In each case, a tap in a series resistance circuit (44 to 53) is thus activated. The dry-reed switches are disposed next to one another in a plurality of rows on an elongated carrier strip (10), axially parallel with the longitudinal axis of the carrier strip. A carrier strip of this type with dry-reed switches (34, 43) and resistors (44 to 53) mounted on it produces, within a narrow cross-section, a potentiometer with closely stepped measured value output. <IMAGE>

Title: Membrane support structure for artificial kidneys - having honeycomb shape with sec. layer at lower level to create blood passage of minimum vol. between dialysis membranes
Inventor: SIGDELL JAN-ERIK DR
IPC: A61M1/22
Filed: 1978-03-14
Abstract: Support structure for artificial kidney membranes consists of honeycomb shaped cells with an internal support structure at a lower level. When a membrane is stretched across the support, it takes a concave profile into the hexagons of the honeycomb. The unit is then formed by placing these supports together offset to each other. The flow passage for the blood is then formed by two membranes mounted face to face to create a flow passage between them. Used in artificial kidneys. System gives improved distribution of blood in the system and has a smaller volume of blood in it which is lost at the end of the treatment.
