Title: Electric circuit which expels water from clay - by using electro osmosis rods driven into clay at intervals, with cathodes connected to water-extraction pump
Inventor: WAGNER HARALD DIPL ING DR
IPC: E21D9/00
Filed: 1979-08-23
Abstract: The circuit has electrode rods (1,2) driven into the face of the clay at 1-4 m intervals. The rods are driven into the clay a distance of 2-6 m. Alternate rods are connected to the positive pole of a voltage supply whilst the remaining rods are connected to the negative pole therefore become cathodes and water collects in their vicinity. The cathode rods may be hollow and connected to a water pipe (7) which carries the water away. The pipe is connected to a suction pump. The voltage supply is at least 10V. This method of drying out the clay to make it rigid and able to bear loads can be applied to any excavation work in clay.

Title: Lighting for toy railway - includes different lamps driven by adaptable voltage supply obtained using voltage stabiliser
Inventor: KILIAN HELMUT
IPC: A63H19/20
Filed: 1979-10-22
Abstract: In the field of railway models a variety of lamps is employed to imitate those in real railway equipment. Some are for a relatively high voltage such as filament lamps whereas the solid state light emitting diodes need only 5 volts. By interposing a voltage stabiliser (5) between the supply terminals (1) and each respective lamp load (2), the voltage supply, which is primarily to suit the electric motors used, can be reliably adapted to drive the various lamps independent of supply conditions and their transient variations.

Title: Mixer for building or sealing materials - where stirrer blades are only coupled to driving motor when mixer lid is closed
Inventor: PLASBERG HANS-DIETER
IPC: B01F15/00
Filed: 1979-10-15
Abstract: Mixer contains a separate stirrer cage, and is closed by a lid on which a stirrer motor is mounted. When the lid is closed, mechanical coupling is made between the drive shaft of the motor and the stirrer cage; and this coupling is automatically disconnected when the lid is opened. Mixer lid is pref. provided with a seal so that a pressure cooker effect is achieved when hot mixing techniques are employed. Advantages include easy loading and unloading of the mixer; rapid heating times during hot mixing; and worker safety is increased because the stirrer cage stops automatically when the lid is opened.

IPC: F21K2/08
Filed: 1979-12-12
Abstract: The cell for d.c. operation and with parallel electrodes, is suitable for carrying out electrochemical synthesis processes. It uses an electrically low conductivity solution containing a medium which ensures the minimum possible conductivity and an electro chemiluminescent substance having a maximum concentration. This substance may have a higher concentration than the low conductivity medium, and forms a saturated solution.

Title: Control mechanism for slides for multi-spindle automatic lathe - has interconnected gear drive to prevent collision between slides
Inventor: LANGER DETLEF DR ING
IPC: B23Q39/04
Filed: 1980-01-25
Abstract: An eight spindle automatic lathe has the tools for two adjacent spindles mounted on slides which run in guides on a common bracket. The movements of the slides are controlled by integral toothed racks which mesh with toothed quadrants. The quadrants are mounted on parallel shafts which each carry a second quadrant which mesh with one another. The slides thus always move in unison with the result that there is no risk of collision either between the slides themselves or between the tools mounted on them.

Title: Transfer printing machine with integrated finishing section - gives high quality printing with increased productivity and reduced power consumption
Inventor: EHEMANN GERO
IPC: B41F16/02
Filed: 1980-03-12
Abstract: A transfer printing machine for fabric incorporates a post-printing finishing section, in which the still-hot fabric is vibrated, steamed, super-heated, and cooled, before re-winding. The fabric is carried through the finishing section on a conveyor which follows on immediately from, and in the same plane as, the presser felt on which the fabric is removed from the printing drum. The printing cylinder is heated by a combined oil/infra-red process which ensures continuous, high-precision temperature control. This procedure gives better-qualityrints, partic. when applied to knotted pile fabrics, and improves the fabric handle. It eliminates intermediate batching, storage and transport operations, giving increased productivity and considerable savings in space and in power consumption.

Title: Anti-side-tone cradle switch circuit - obviates transformer and couples balanced telephone subscriber's pair to four-wire line
Inventor: BIRTH WINFRIED DIPL ING
IPC: H04B1/58
Filed: 1980-05-23
Abstract: Each of the two wires (a,b) of a balanced two-wire telephone line (ZL) is connected via a large resistor (R) to the two inputs of an operational amplifier (V). Each wire is connected via a line terminating impendance (Z/2) to one of two inputs (Sa,Sb). of a balanced input circuit (VS) belonging to a 4-wire line (VL). The amplifier's output is connected to one of the two inputs to the output circuit (VE) of the 4-wire line. The amplifier's inputs are also each cross-coupled via a second large resistor (2R) to one input of the 4-wire input circuit. The second large resistors are twice the value of the first large resistors (R). A trigger containing a transistor monitors the output voltage from the amplifier and causes the d.c. reference voltage to change so that the output signals of two operational amplifiers lying in the output circuit of the 4-wire line are at least roughly equal. Further circuits are used to detect imbalance in the current flowing via the 2-wire line and for monitoring loop closure.

Title: Heat exchanger for ventilation equipment - consists of two grooved plastics layers welded together to form fluid circulating channels
Inventor: RIGOS EFSTRATIOS DR ING
IPC: F28D1/03
Filed: 1980-06-26
Abstract: The heat exchanger made of plastics material, is suitable for cooling towers, heat extraction from air conditioning equipment etc. It is made from two layers (4,5) with a set of semicircular section parallel channels along one face of each, focussing the heat exchanger conduits. One medium circulates through these conduits (3) and a second medium flows around the outside. The two contacting surfaces forming the joint (6) between the two layers are welded together. The pressure of the medium flowing around the outside is greater than the pressure of the medium flowing through the conduits. The channels do not extend the full length of the layers, and the remaining edge zones (7) are used for mounting the heat exchanger in a frame.

Title: Input modulator for matrix display - uses reception function based on transistor giving serial data transfer
Inventor: MILOSIU JOHANN-MARIUS DIPL ING
IPC: G09G3/32
Filed: 1980-07-19
Abstract: The input signal modulator is for a matrix display with reception facilities. Data transfer takes place serially with the display connected and from a magnetic tape or other external source. The modulator circuit is based on the blocking and conducting characteristics of a transistor under the influence of a controller. It scans the data recorded in the matrix when required. The results are multiplexed in synchronism with the scanning and transferred to the external data medium via the serial data output. The transfer is achieved by passing the signal from each photo-memory-cell via a capacitor and an isolation diode to the serial data output. During reception the modulator transistor remains blocked and current limiting resistors connect the NPN transistor collectors to the positive voltage.

Title: Changeover circuit for mains supply - comprises combination of rectifier with electronic flip=flop with threshold values for rising and falling mains voltage
Inventor: SIESTRUP FRIEDRICH
IPC: H02M1/10
Filed: 1980-10-04
Abstract: The circuit is designed for the current supply of electric appliances and provides automatic matching of the circuit parts to the voltage of an a.c. mains. The change-over of the mains current supply to the respective mains voltage uses a rectifier circuit combined with an electronic flip-flop. The latter comprises threshold values with hysteresis characteristics both for a rising and a falling mains voltage. After exceeding a threshold value, it trips a switching step switching the rectifier circuit between a half-wave to a full- wave rectification with voltage doubling. This switching step is carried out by a thyristor, or by an electromagnetic relay. Pref. the change-over switch actuates different positions of a mains transformer tap changer. In this manner the mains current supply part is without any iron and enables matching of alternating voltages between 100 to 250 V without manual switching.
