In this context of changing and challenging market requirements, Gas Insulated Substation GIS has found a broad range of applications in power systems for more than two decades because of its high reliability, easy maintenance and small ground space requirement etc. SF6 has been of considerable technological interest as an insulation medium in GIS because of its superior insulating properties, high dielectric strength at relatively low pressure and its thermal and chemical stability. SF6 is generally found to be very sensitive to field perturbations such as those caused by conductor surface imperfections and by conducting particle contaminants. The presence of contamination can therefore be a problem with gas insulated substations operating at high fields. If the effects of these particles could be eliminated, then this would improve the reliability of compressed gas insulated substation. It would also offer the possibility of operating at higher fields to affect a potential reduction in the GIS size with subsequent savings in the cost of manufacture and installation. The purpose of this paper is to develop techniques, which will formulate the basic equations that will govern the movement of metallic particles like aluminum, copper in a coated as well as uncoated busduct. In recent years, the areas of industrial application of AC drives, especially Induction machine based on DTC technique has gradually increased due to its advantages over the other techniques of control. However conventional DTC suffers from high torque ripple and variable switching frequency. This paper, propose a method to reduce torque fluctuations, where the circular flux vector is divided into twelve sectors and is compared with conventional DTC method where the flux vector is divided into six.

He’s superficially defending Jim’s sexual dalliances, saying no one is perfect, many celebrities did the same thing, etc. But the problem with the dozens of sexual references in Jim Reeves His Untold Story is not the extreme over emphasis on sex Jordan even shockingly refers to the size of Reeves penis!

At first the speeds were not standardised but ranged between 65 and over rpm, but in the s an average speed was around 78rpm. The first disc recording machines were weight driven with the speed controlled by a governor and different calibrations between machines could lead to speed differences. When electrical recording was first used in , it was used for the soundtrack of films and so a precise speed was needed to keep in sync with the picture.
In America using 60Hz mains, the speed of electric motors is either or rpm. Using a rpm motor with a A similar calculation for England using 50 Hz mains gives a speed of

Labelography of Home Recording Discs Note: I haven’t kept up with this project over the past few years, but here, at least, is an updated version of the labelography page, with certain links fixed. The principal goal of this project is to assemble an illustrated list of label types found on home recording swiss rolex discs of the mid-twentieth century. A further and perhaps more important goal is to produce a dating guide for home recording discs.
Obviously there is no way to determine the date of an undated home recording with certainty based only on rolex replica the label type. People often used blank discs many years after they were originally produced; I have discs in my collection manufactured during World War Two but recorded in the s, and some people are still making recordings on vintage blanks. However, by determining approximately when each label type was originally introduced, we can at least come up with a set of earliest possible recording dates for disc home recordings.
For example, a disc with a label type introduced about cannot have ofake omega watches been recorded earlier than that, although it could have been recorded much later. Furthermore, it is likely that a majority of discs were in fact recorded a short time after their initial sale, so we might eventually be able to hazard educated guesses of, say, “circa ” based on a given label type.
When was this recording made? But how can we figure out when each label type was introduced? That’s where you can help if you have any home disc recordings in your possession.

Hi, Philco also manufactured at least one 33rpm radio-phono in , their 23X: Certainly similarities in the tonearm and player are evident. Most examples of the Concert Grand used a Victor pickup and a Samgomo motor, although some examples are known with the General Electric Induction Disc motor. The vintage models and used Victor pickups on the “inertia” tone arm, and were fitted with General Industries “Green Flyer” motors. The combination used the Victor pickup on a Capehart drop changer.
It appears that early combinations continued to use the green flyer motors. I suspect that the decision by RCA Victor to dispose of a considerable quantity of their induction disc motors at cut prices in the spring of may have a grreat deal to do with the appearance of these motors in Philco combinations in the succeeding years. In that year it was assumed that the industry was duing, and would take only a couple of years to wind up.
