Title: Heat treating refractory bricks contg. tar - to remove volatile constituents in tar content by heating in oxygen free inert gas
Inventor: FRISCHBUTTER HERBERT ING GRAD
IPC: F27D1/18
Filed: 1978-03-08
Abstract: The refractory materials are bonded or impregnated with tar, and are esp. bricks made of dolomite and/or magnesite or chamotte. Treatment consists of heating the bricks in an inert gas (a) free from O2; and then cooling the bricks in inert gas (b) free from tar constituents until the bricks are below the ignition temp. of the carbon remaining in the bricks. In the pref. process and plant, a tunnel kiln is used, and gases (a,b) are obtd. by burning gas or liq. fuels; and the volatile constituents in the tar are burned in the inert gas with the aid of heat and O2 so that new inert gas free from O2 is obtd. The kiln has an air lock followed by tempering and cooling zones fed with inert gas, then an air cooling zone. The bricks are heated to >=700 degrees C so they are suitable for use without causing environmental pollution; and without explosions in the heat treatment plant. The bricks are used to make converter linings.

Title: Monitoring anodic oxidn. water treatment - by radiation source and sensors responding to gas bubbles presence
Inventor: KIRMAIER NORBERT DR ING
IPC: G01N29/42
Filed: 1978-08-16
Abstract: The treatment is used in the pharmaceutical industry to produce sterilised water, and is monitored by a radiation source (ultrasonic, visible, infrared, ultraviolet light or nuclear radiation) and a facing receiver. The measuring system is applied in an area where anodic oxidn. has formed or concd. gas bubbles. This provides a more reliable check of the function than checking the current density, cell voltage or oxygen determination. Photosensors at the opposite side and on the same side detect the transmitted and reflected radiation. The electrochemical treatment efficiency of the anodic oxidn. cell is related to the number of gas bubbles and the ratio of reflected to transmitted radiation.

Title: Coin sensing appts. using permanent magnet - has guides directing inserted coin to cause change in magnetic field to induce EMF in sensor coil on pole extension magnet
Inventor: HOVORKA JIRI J
IPC: G07D5/08
Filed: 1978-08-22
Abstract: The coin indicating appts. uses a sensor containing a permanent magnet and a pole extension magnet spaced a predetermined distance from one pole to form a space including a portion for receiving coins and similar. The permanent magnet polarises the pole extension magnet to establish a magnetic field that is changed by an interposed coin or similar. A sensor coil having a predetermined number of ampere-turns is disposed about a portion of the pole extension magnet. A change in the magnetic field induces an e.m.f. in the coil to provide an output signal uniquely indicative of the interposed coil or similar. Guides are provided to direct the latter into the magnetic field.

Title: Matched battery charging circuit - automatically sets battery to standardised charger by using thyristor to bleed off unwanted current
Inventor: HOEHT WOLFGANG
IPC: H02J7/00
Filed: 1979-08-02
Abstract: The charging circuit connects a battery of low rated capacity to a charger of high rated capacity. The charger is shunted by a thyristor in series with a diode and variable resistor. The thyristor is controlled by a Zener diode and shunts away part of the current delivered by the charger so that only a fraction of the total available current reaches the battery. The diode turns off the thyristor when the charger is switched off. The variable resistor sets the fraction of current shunted away from the battery. Two series diodes connect the thyristor and charger to one pole of the battery to prevent the battery discharging. These two diodes are shunted by a resistor that allows a voltmeter to be connected to measure the battery's charge state.

Title: Desalination plant pressure vessel heat-transfer system - stretches vessel by internal pressure when winding pipe coil between ribs
Inventor: KUECKENS ALEXANDER
IPC: F28D1/06

Title: Warning system for vehicle - flashes lights when brake pressure exceeds given limit to warn other road-users of hazard
Inventor: KLINGLER WILHELM
IPC: B60Q1/44
Filed: 1979-11-09
Abstract: The warning system generates optical signals in a vehicle to warn other drivers of an accident or a hazard. The warning signals are generated automatically when the braking force of the vehicle exceeds a given limit and they remain on for a given length of time or until the driver switches them off. The warning signals are produced by flashing the lights of the vehicle on and off. An acoustic warning signal may also be emitted. The braking pressure is monitored by a threshold switch responding to the pressure of the braking fluid.

Title: Hand operated valve for oxygen lance - where spring loaded catch holding valve in open position is automatically released if lance is exposed to shock or impact
Inventor: MARMANN HORST
IPC: C21C5/46
Filed: 1980-02-01
Abstract: The lance is fed with oxygen via a valve contg. a plunger; and hand pressure on a lever moves plunger against the force of a coil spring to open the valve. The hand lever can be moved under a spring, so that the valve may be kept in its open position even when a human hand is removed from the lever. If the lance is exposed to impact or shock while the valve is open, e.g. if the lance falls onto the ground, the spring jumps back into its position of rest, so valve closes automatically. Spring is pref. a leaf spring moved by a peg, but alternatively a peg fitted with a coil spring can be used. A simple safety device, which prevents oxygen flow through the lance if an accident occurs, esp. if the lance is dropped.
