Title: Pesticide spray system for plants - has two independently movable halves with opposing inlet and outlet to avoid environment contamination
Inventor: EBELING HELGE
IPC: B05B14/00
Filed: 1989-04-28
Abstract: When spraying plants with pesticides, the fluid to be sprayed is atomised into two or more smaller air jets which are combined into two air jets which flow into the plant from outside sides at an adjustable angle. After leaving the plant the air jets are taken up by two intake opeings set opposite the air outlet openings. The axes of the air jet directions are one behind the other. The air jet directions are one behind the other. The air outlet  openings and intake openings are pref. set in one structure designed, so that it prevents an air exchange with the surrounding atmosphere upwards and to the sides. ADVANTAGE - This device is safer for the environment.

Title: Etchant contg. sodium used to prepare plastics - for nucleation and plating by electroless technique, esp. preparing polyimide for copper plating
Inventor: MELNITZKI ARTHUR
IPC: C23C18/22
Filed: 1989-05-18
Abstract: An etchant contg. Na is used for prepg. plastics surfaces for nucleation and electroless metal plating. USE/ADVANTAGE - The technique is esp. useful for prepg. polyether-imides and esp. polyimides to etch or swell the surface, so that a strong bond is obtd. on nucleating with PdCl2, before electroless Cu plating. A strong bond is obtd. and any metal structures, e.g. Cu wiring tracks, already present are not damaged. In an example, a polyeter-imide substrate was degreased, then immersed for 1/2-2 min. in a bath of naphthalene-Na at room temp. After drying, it was nucleated with PdCl2 and plated chemically with Cu, which adhered very firmly.

Title: Multiple computer system for process control - has I=O circuits connected via voting circuits to I=O units for rapid operation
Inventor: WEINERT ALBRECHT DR ING
IPC: G06F11/18
Filed: 1989-06-09
Abstract: The multiple computer system has several asynchronous computers (CPU1 - CPU3) connected to input/output or I/O units (EAG1 - EAG3) via voters (EAV1 - EAV3) comparing input signals synchronously transferred via bus lines (BL1 - BL3) and warning of discrepancies. Each computer passes signals to an associated I/O circuit (EAS1 - EAS3) immediately after processing each program section. Each I/O circuit detects and warns of the transfer of signals to the other I/O circuits. The signals are transferred from the I/O circuits to the I/O units. USE/ADVANTAGE - Parallel processors in process control applications. Rapid multiple processor operation is achieved.

Title: Handling mixt. of water and lacquer sludge - by withdrawing sludge from spray-painting booth by outlet funnel below water-sludge mixt. in receiving vessel beneath booth
Inventor: IPSEN HARALD
IPC: B05B15/12
Filed: 1989-06-13
Abstract: The mixt. of lacquer sludge and water is collected in a receiving vessel under the painting booth.  A movement of the mixt. at or just below its surface is caused, and in the neighbourhood of this motion the mixt. is withdrawn through an open-topped outlet  funnel.  The top edge of the funnel is rectangular or circular and has a serrated or indeneted shape and is positioned about 1 cm below the liq. surface.  The liq. in the lower part of the receiving vessel is kept in circulation by a pump.  The mixt. passes from the outlet funnel to a separating system, and the return water flow from this system, as well as the flow produced by the circulating pump, are directed so as to produce a flow of the liq.  in the receiving vessel towards the outlet funnel. USE/ADVANTAGE - Used in spray painting or lacquering booths having walls which are kept clean by a flow of water or  a water curtain.  A simple, effective, and economical means of withdrawing the mixture of water and sludge collected below the booth is provided.

Title: Sterilisation of contaminated waste from veterinary isolation area - by adjusting moisture content of diverse components and sterilising within isolation area with sterile outlet sealed to wall
Inventor: KINZLER GEORG
IPC: A61L2/07
Filed: 1989-08-22
