Patent NL-6601494-A (NL)
IPC: C07C29/80
Filed: 1966-02-04
Abstract: Mixtures of di- and poly-glycols are produced by diluting with water the distillation residue obtained in the production of ethylene glycol from ethylene oxide and water, and removing from the diluted residue the impurities which separate.  The mixture obtained contains mainly di- and triethylene glycol, the impurities removed being polymers which precipitate on addition of water and inorganic salts which separate when the water is subsequently distilled off.  The glycol mixture, which initially has a high pH, may be used, after neutralization and bleaching if desired, to impregnate wood to reduce its shrinkage.ALSO:A mixture of glycols obtained as a distillation residue in the production of ethylene glycol from ethylene oxide and water is purified by diluting with water and removing the impurities which separate, and may then be used to impregnate fine wood to reduce shrinkage and prevent the formation of checks.  The glycol mixture, which has a dark brown colour, may be bleached before use e.g. with hydrogen peroxide and may be used in association with a plastic binding agent, e.g. a phenol-formaldehyde or urea-formaldehyde resin.

Title: Hydrolysis of an epoxy compound to give a dihydroxy - compound useful for modifying epoxy based paints
IPC: C08G59/14
Filed: 1979-04-12
Abstract: A 1,2-epoxyalkyl compound can be hydrolysed to the corresponding dihydroxy compound by (1) heating with aq. oxalic or malonic acid in the absence of air and under at least the pressure generated, and (2) distilling the mixture at a temperature sufficient to decompose the acid used. Preferably the epoxy compound is first mixed with an inert solvent such as an aromatic hydrocarbon on a ketone; this mixture contains 20-75%, esp. 35-50%, by wt. of the epoxy compound. Reaction is typically at 50 degrees-374 degrees C, for 15 min to 10 hours. The wt. of acid is 0.1 to 3%, esp. 0.5-1%, based on wt. of epoxy. The water concentration is 2 to 40, pref. 10 to 20 moles per mole of resin. Specifically the epoxy is the diglycidyl ether of bisphenol A. The hydrolysis is easily performed. conversion can be more than 99%. The acid catalyst is completely removed during the distillation and the hydrolysed product can be used without further purification as a diluent and a compatible additive for an epoxy resin which may be identical to the original starting material. In particular 1 to 20% by wt. of the hydroxy component is added. Main application of the mixture is as a coating or a paint vehicle. Addition of the hydroxy compound increases the speed of hardening of the epoxy resin and lowers the temp. required. The mechanical and chemical properties of the cured resin are not lowered by the hydroxy component and the shelf life of the uncured mixture is long.

Title: Automatic circulation pump of central heating system - increases efficiency by independent switching program for pump motor
IPC: F24D19/10
Filed: 1979-09-12
Abstract: The central heating system has an automatic circulation pump, which can be used in standard central heating plants. It achieves considerable savings in electricity and a small amount of gas without affecting the temperature regulation system. The circulation pump is switched off twenty minutes after the room thermostat has switched off the burners of the gas supoly. The circulation pump is switched on automatically for twenty minutes if a room thermostat is not switched on for a period of 3.3 days. This prevents the pump for caking up.

Title: Method and arrangement for adaptive control of electroerosion based working process
Inventor: GARBAJS VITO
IPC: B23H1/02
Filed: 1999-04-06
Abstract: The automatic control of the electroerosion based processing according to the invention is performed in such a way that the process adapts to the model for such a process, which during processing concurrently adapts to the current situation, by adaptive learning. The upper and lower limit voltages for the area of the required voltage are progressing during the electroerosion process, depending on the time of the current discharg, are calculated for each individual discharge based on stored data on sampling the time based voltage progress of the active discharge processes. The current discharge is perceived as a non-standard discharge as soon as its voltage leaves the limited area by exceeding one of the two limit voltages. The automatic setting of limit voltages simplifies the control process and allows a higher automation level and at the same time eliminates the operator factor. In order to meet a required progress the adaptive process is reliable and features short reaction times. It allows precise processing providing high quality product surface.
