Title: Method for regulating the voltage at the delivery points in a network for distributing electric energy
Inventor: GRIFFIOEN JAN H
IPC: H02J3/00
Filed: 1993-04-29
Abstract: A B S T R A C T         The invention relates to a method for regulating the voltage at which electric energy is supplied at the delivery points in a network for distributing electricity. The voltage of electric energy supplied through a high-voltage network is reduced to a voltage suitable for a medium-voltage network by means of at least one variable transformer. The voltage of the electric energy in the medium-voltage network is reduced, by means of at least one transformer, to a voltage suitable for a low-voltage network supplying the electric energy to the consumers. The adjustment of the variable transformer between a high-voltage network and a medium-voltage network is influenced by the actual voltage measured and the current or load at the output side of the variable transformer. The voltage prevailing at the delivery point is measured at the location of at least a number of consumers and the variable transformer is set partly in dependence on the voltage thus measured at the consumers' location.

Title: Method of restoring the bore of a turbo-machine rotor
Inventor: AMOS DENNIS R
IPC: F01D5/02
Filed: 1993-09-17
Abstract: ABSTRACT OF THE DISCLOSURE         A method of restoring the bore of a rotor in a turbo-machine rotor having a centrally disposed bore by the steps of (i) depositing a weld material onto the bore surface over at least a portion of the axial length so as to reduce the inside diameter of the bore and roughened the bore surface over the portion of the axial length and (ii) machining the weld material so as to smoothen the bore surface.  According to the method, the step of depositing the weld material is performed so as to deposit a weld bead circumferentially around the inner surface in a multi-pass process by inserting a welding nozzle into the bore and simultaneously impart both rotational and linear relative motion between the rotor and the welding nozzle.  The bore inner surface is pre-machined to  increase  the  inside  diameter  prior  to  the  step  of depositing the weld material and post-machined to the original bore diameter following the welding.

Inventor: BANKS HENRY J
IPC: A01N31/02
Filed: 1993-01-15
Abstract: The gaseous chemical compound, carbonyl sulphide, has hitherto been unknown as a fumigant for the control of insects and mites. Experiments have shown conclusively that carbonyl sulphide can be used as such a fumigant, with fumigation propert-ies comparable to those of phosphine and methyl bromide. The effectiveness of carbonyl sulphide against insects (both adult and immature stages), mites, termites and moulds is demonstrated. In addition, its low absorption by grain, lower flammability than phosphine, lack of influence on seed germination, and apparent environmental safety make carbonyl sulphide particularly bene-ficial as a fumigant of stored grain. It may also be used to fumigate other stored produce (including perishable foodstuff), soil, timber and spaces (such as buildings) and any material likely to be infested by insects or mites, ar act as a source of such infesta-tion.
