Title: Colour TV games circuit - displays coloured symbols on screen without using colour modulator by direct connection to colour output stage
Inventor: WAHL PETER
IPC: A63F13/98
Filed: 1976-09-17
Abstract: The colour television games circuit allows coloured symbols to appear on the screen without using a colour modulator. The output of the circuit is not HF modulated. Output signals describing a symbol or associated symbols are applied directly to the receiver's colour output stage or to the video output stage via the colour matrix if one is present. Associated symbols are entered into one or more colour output stages and converted into the appropriate primary colour or colour mix which then appears on the screen. The sync. output of the circuit is connected to the receiver's sync. circuit. The receiver's HF input circuit is switched off.

Title: Cooling of Contact process sulphuric acid - using double absorption with acid recycle via air dryer
Inventor: JENNIGES ERNST
IPC: C01B17/765
Filed: 1977-01-28
Abstract: Gas drying and SO3 absorption during the mfg. of H2SO4 from SO2 using the air oxidn. extract process involves drying the feed air with H2SO4. The SO3 is then absorbed into H2SO4 from the contact gas. H2SO4 is extd. from the SO3 adsorption stage after passage through without cooling at 80-120 degrees C. It is then cooled to 40-70 degrees C in a cooler and fed to the air dryer. It passes through without further cooling and is fed on to the final SO3 absorption stage and from here to the intermediate absorption stage without further cooling. A stream of product acid can be taken either from the outlet of the dryer or the absorption stages. The plant is designed to simplify and reduce the amt. of cooling equipment necessary for efficient operation thus reducing the capital cost.

Title: Automatic metering of quantities of gas or liquid - using logic switches and comparators to energise relays in the control circuit
Inventor: RICHTER HANS
IPC: B01J4/00
Filed: 1977-01-31
Abstract: Accurate setting of gas and liquid quantities is achieved by selector switches attached to adjustable counters. These have an electronic input proportional to the quantity to be measured and an output loading to a comparator. One comparator is connected to >=1 further selector to st a throttling value. When this is reached, a control device e.g. a valve is used to reduce the total flow. A further circuit is ten used to completely shut off the flow when the full amount has been delivered. The comparator device contains a logic circuit with an input from an electronic counter and one output loading to the input to the comparator while another goes to the flow control device. An output is generated when a certain flow has passed and the flow finally shut off when the counter reaches zero. Used for repetitive automatic metering of discreet quantities of a gas or liquid. The system described gives an automatic throttling of the flow before the final shutt off.

Title: Coin testing machine using AC field - has oscillator voltage corrected, between passages of tested coins using differential circuit
IPC: G07D5/08
Filed: 1977-05-25
Abstract: The field is generated by a test coil. A measurement and control voltage is produced by a differential circuit from the difference between a reference voltage and an oscillator voltage. It controls the oscillator voltage through a control device until a specified relation between reference and oscillator voltages is reached. The measurement and control voltage is used as a criterion during coil testing, by finding whether it lies between specified limits, as in 2546685. An additional fine adjustment of the oscillator is carried out ot eliminate temperature and long term effect influences. Short influences of the passign coil on the AC field are left uncorrected. This is achieved by holding the corrections at the levels they had before the coin entry.

Title: Washing granulated plastics waste in turbulent zones - formed by helical thread of revolving screw ensuring uniform washing throughout
Inventor: WENZ KARL-HEINZ
IPC: B08B3/04
Filed: 1978-02-01
Abstract: Method of washing and drying bulk granular material, esp. fragmented plastics waste having either a higher or lower density than the wash liquid, followed by drying of the material, opt. after spraying, is claimed. The bulk granular material is passed through the wash liq. along a number of helical thread-shaped turbulence zones, sepd. from one another, the wash liq. flowing perpendicularly to the direction of conveying of the bulk material. Pref. after the turbulent zones, the bulk materal passes through a rest zone of no turbulence before it is removed from the liq. Pref. the treatment time and intensity can be varieD. The bulk material is pref. dried after leaving the washing zone. By constraining every position of the granular material to pass through every turbulent zone uniform treatment is achieved and no part of the bulk material can reside for any length of time in a 'dead' zone, resulting in uneven washing.

Title: Control circuit for arm of industrial robot - has acceleration or deceleration of motor regulated for each direction of motion
Inventor: PEYR FRANZ
IPC: G05B19/41
Filed: 1978-02-14
Abstract: The movement of the arm of an industrial robot is controlled simultaneously in three mutually perpendicular directions. The required position in each direction is fed into a computer which transmits a signal to common interpolator for all three directions. A profile generator the transmits a signal to control the movement in one particular direction. This signal is determined by the instantaneous position of the robot arm from the indicator and the speed of the motor as measured by the tachometer. This signal gives the required acceleration or deceleration of the motor.

Title: Ion exchanger fertiliser for potted flowers - applied for long periods through wick
Inventor: REIHLEN ROLAND DR
IPC: A01G27/04
Filed: 1978-03-23
Abstract: Potted flowers are fed an ion exchange fertilizer over long periods of time by using a capillary, such as a wick, to take up the exchange ions to the roots, embedded in soil. A cup with the ion exchanger fertilizer granules in water carries on its top the flower pot. A wick passes through a hole in the flower pot bottom into the water in the cup. The soil in the flower pot does not impede the ion exchange and any supersaturation with fertilizer is successfully eliminated.
