Title: Aqueous resin dispersions - for treating tissue wounds of plants
Inventor: SCHEIDLER WILHELM
IPC: A01N3/04
Filed: 1972-09-29
Abstract: Agents based on aq. dispersions of emulsions of plastics and/or natural resins are used for the treatment of tissue damage on plants and in the budding or grafting of trees or shrubs. They may be produced by combination of a variety of raw materials, and may be coloured by admixture of chemical or mineral pigments. The pigments impart a colour matching that of the bark of the plant which is to be treated, both for aesthetic reasons and because a matching colour has been found to give the most favourable conditions of temp. (due to light-absorption) for healing of the damaged plant-tissue covered by the agent.

Title: Removing cast ingots from moulds - by carrying them through tank for cooling then removing for stacking
Inventor: DROSTE GUENTER DIPL ING
IPC: C08F218/02
Filed: 1973-02-24
Abstract: Copper anode plates or ingots are lifted by a fork from their moulds and moved to a position above a cooling tank. The fork lowers the ingot onto a frame which in turn lowers the ingot onto a tiltable yolk immersed in the cooling tank. The yolks are advanced long the cooling tank by chains. At the far end of the tank guides tilt the yolks to a horizontal position and ingots upon them come up against hooks on a take-off trolley. The take-off trolley moves in the same direction as the chain but a greater speed so that an ingot held thereon is removed from the tank and finally stacked upon a bed.

Title: Effluent decontamination by two stage evaporation - with interstage superheating, filtration, distillation and column separation
Inventor: MUTKE REINHOLD DIPL ING
IPC: G21F9/08
Filed: 1973-03-27
Abstract: Effluents, particularly those contg. iodine isotopes as iodate, iodide, iodine or methyl iodide, can be decontaminated by evaporation and filtration. The effluent is passed through a two-stage evaporator, fitted with droplet separators. The vapours are dried by superheating between the first and second stage, followed by a mechanical filtration (cloth, electro- or molecular sieve) of the secreted solids. This system yields a satisfactory distillate with an activity of less than 10-7Ci/m3. It is a simple and economical way of producing reliable results within the antipollution statutes.

Title: Individual machining station interconnection system - controls station and conveyor dependent on pressure of incoming workpieces
Inventor: GAISER DIETER
IPC: B65G43/08
Filed: 1973-08-09
Abstract: The system is for use where a series of processing or machining stations for the workpieces are connected by a conveyor, but do not work in synchronism with each other. Each station is equipped with means for testing the pressure of accumulated workpieces, which in turn control switches for the station concerned, and/or the conveyor. Typically a spring loaded lever can be used, deflected by a preset force exerted by the workpieces, and returning to the starting position afterwards. Its height above the conveyor can be adjustable.

Title: Welding-together plastic window-frame profiles - by pressing against heated plate for predefined time and then pressing together
Inventor: URBAN JUN JOSEF
IPC: B29C65/00
Filed: 1973-09-04
Abstract: Welded connection is produced between the plastic profiles of a window frame or similar article by pressing the profiles during a predefined time against a heated welding plate, withdrawing the profiles, and pressing them against each other. The movement against the welding plate is limited by a fixed stop, and the predefined time is started when the movement against the welding plate is limited by the fixed stop. Process always gives the correct time for heating the welding surface independently of the cross-section of the profiles. Insufficient heating and overheating are both avoided.

Title: Furniture component acceleration mechanism on production track - has slipping high speed conveyor with inlet end raised and lowered
Inventor: GRON GUENTHER DIPL-ING
IPC: B65G43/08
Filed: 1973-11-02
Abstract: The mechanism is for use in the transport of components, two or more at a time and at the same height, in the furniture manufacturing industry, the items being delivered by a low speed feed conveyor to a second one of higher speed. The second conveyor belt is of the slipping type, where the drive shafts can turn freely in the event of the items being braked or halted. At the inlet end at least it can be raised and lowered in relation to the level of the feed conveyor, and at the discharge end of the latter is a row of detectors, typically photoelectric cells, running at right angles to the direction of travel. After the passage of a row of plates has caused the interruption of the lifting movement of the second conveyor from below the level of the feed conveyor, these detectors cause this movement to be resumed and the second conveyor to be raised above the first.

Patent DE-2421120-A1 (DE)
Title: Improved distribution of conditioned air over square grille - achieved by deflecting incoming air round the square with a baffle
Inventor: REGENSCHEIT BRUNO
IPC: F24F13/06
Filed: 1974-05-02
Abstract: The air enters the chest from a pipe before passing through the louvred ceiling grille. By being left a clear passage, the incoming air blows straight across the chest, and most of it passes through the louvres farthest from the inlet pipe. The baffle, hinged like a door and placed close against the inlet pipe, serves, when partly open, to deflect the air round the square so that it passes more equally through the various louvres. The baffle can be used to cut off the supply through the inlet pipe; if desired, it could form part of an automatic control system.

IPC: H02M1/00
Filed: 1974-08-19
Abstract: The high power factor alternating current regulator for heaters lights etc. has the alternating current source connected to the input diagonal of a diode bridge. The bridge output diagonal supplies the series combination of the load and a variable direct voltage source. The variable voltage source consists of a resistor and a switch in series and both shunted by a capacitor. The switch may consists of thyristors or transistors and may have a regulator with hystereses. This alternating current regulator two-point is of simple construction and allows the alternating current or power to be continuously regulated with a low reactive component.

Title: Aircraft lift coefficient sensor - has speed and area loading input to adjust per-formance of aircraft
Inventor: MEHRLE WOLFGANG
IPC: B64D43/02
Filed: 1974-12-11
Abstract: The measuring instrument is used e.g. to determine the profile geometry and/or the surface geometry and/or the area loading of various systems used in aircraft. It determines the lift coefficient in relation to at least two of the following flight parameters: the aircraft speed, a multiple of the load, and the area loading. The output of the instrument is fed to an adjusting mechanism which optimises the performance of the aircraft. The lift coefficient which has been determined can be displayed optically or indicated acoustically or by other suitable methods. The indicator is connected to an alarm device which gives a signal when the maximum lift coefficient has been reached.
