Ba lanc in g Special WITH the advent of mechanWheels Which Run VT ism running at extremely at Great Speeds . high speeds, true balancing becomes of primary importance, for upon it depends largely the life of the machine and of its individual parts. The human factor in testing vibrations becomes unsatisfactory as, by touch, one cannot feel those occurring much above 20,000 per minute. With rotating parts, balancing at a lower speed is unreliable as stretch takes place at high r.p.m. In this connection there was shown by Reid and Sigrist, Ltd., at the British Industries Fair, Olympia, an electronic dynamic balancer which can be adapted to balance all rotating bodies, gives a constant standard of balance, and needs no special skill in operation. It has recently been adopted as standard by the R.A.F. In operation, two sinusoidal waves are generated by the rotor by means of light beams falling upon the photoelectric cells. One, the reference wave, controls the horizontal movement of the light spot on the screen 424 of the cathode-ray tube; anotner wave, caused by the vibrations resulting from unbalance, controls the vertical movement of this light spot. The apparatus measures the phase difference between the two waves, thus giving a direct indication of the position, on the periphery of the wheel, of the out-of-balance mass.

DIFFICULTIES with which bodybuilders have to contend these days not only include shortages of materials, but high cost of skilled labour. "The situation is perfectly shocking," as one bodybuilder put it to us. Unskilled workers now receive as much as skilled men in 1939, whilst the wages of the latter have doubled. In addition, skilled workers are few in number. The position from the operator's viewpoint is that a second-rate piece of work now costs the same as the best pre-war, and the present-day best is often so high as to be uneconomic. High Labour Costs Force up Prices of

Press Guests of A NICE gesture to the Press, Eastbourne's Mayor r-k trade and technical, and and Corporation . . local, was made during the re cent P.T.A. Conference at Eastbourne. It took the form of an invitation to luncheon at the Cumberland Hotel from the Mayor and Corporation. It was just a happy party, and there were no formal speeches. It is the first time we can remember such an honour being paid to the Press at the various conferences of the industry, and it was duly appreciated.

Midland " Red" Has rINE of the activities on the a Fine Concert \--1 entertainment side of the Orchestra Midland " Red " is a full strength concert orchestra with 58 instrumentalists. This was founded in September, 1943, ;under its conductor, Mr. Norman Parkes. Since then it has given over 50 public performances, many for charitable purposes, and has raised in this way about €1,500. During the summer it will continue educational concerts by arrangement with the Smettiwick Education Department. Next year it is hoped to extend the orchestra's activities by visiting various towns in the Midlands which do not normally have the opportunity of seeing and hearing an orchestra either of such size or of such fine quality as this one.

B.R.F. Welcomes ILST welcoming the ex Short-term Plan for perimental measures to London Traffic . . . relieve traffic congestion,

which are being put into operation in Central London on May 27, and may, later, be extended to the whole area of Greater London, the B.R.F. looks upon these as only a shortterm plan. It points out that the extension of the system of one-way streets and enforcement of the no-waiting order will give some relief, but they cannot absolve the Government from its duty to plan and construct in the immediate future a highway system, combined with adequate parking facilities, which will give to our capital the roads fundamental to its needs.
