72 FLIGHT. JULY 21, 1938. THE INDUSTRY Differential Braking SIMPLICITY is the keynote of the latest Bendix differential control unit for cable-operated brakes, illustrated on this PaSe- . . The general principle is, of course, well known, consisting as it does of hand-lever operation of the brakes in conjunction with a steering-by-brake system connected with the rudder bar. The Bendix unit avoids the necessity for attaching levers, pulleys, etc., to various points on the machine— methods which in some cases result in untidiness and in efficiency. The Bendix Differential Unit. The unit is a compact device, occupying a few cubic inches of space only, and merely requiring to be connected to hand brake lever, brakes and rudder bar. Its fitting, too, is simple, "consisting of four screws or bolts. Between the top and bottom plates swings a main lever carrying two pulleys, round which pass the brake operating cables,' the ends of'which are coupled to the false rudder bar, seen on the left. The false rudder bar is connected to the rudder bar in the cockpit, either by two cables or by a single rod. The main lever is connected to the hand-brake control lever. In order to steer the machine by the brakes the pilot first applies them by the lever to approximately one-third of the maximum amount, and then directs the machine by using the ordinary flight rudder-bar movements. For full brake or parking on the aerodrome, the hand lever is, of course, applied to its maximum extent. A feature of the control is that the brake cables are con nected to the false rudder bar at points so disposed that, when steering on the ground, the increase in braking on the inside wheel is not so great in proportion as the decrease in braking on the outer wheel, thus securing smooth and progressive action. The unit has been arranged for right- or left-handed operation, and is, in fact, readily adaptable to a variety of different cockpit arrangements. Bendix, Ltd., Tyseley, Birmingham, are the makers. The Saro Staff F OLLOWING the article '•'Nautical Interlude " in Flight of July 7, it should be added that Capt. Frank Courtney has been engaged temporarily as a consultant and test pilot, having taken over many flying duties from Fit. Lt. Ash, who remains the firm's chief test pilot. Incidentally, Mr. Perfect, who is now liason officer with the R.A.F. and Air. Ministry, and who is handling publicity, has been with the firm for nine years, two being spent as works manager. Financial Results T HE full accounts of the Bristol Aeroplane Company show that net profits rose last year from £295,089 to £344,575, an increase of roughly 17 per cent. Of this amount the board is transferring a further £100,000 to general reserve, raising this fund to £1,200,000, equal to the whole of the issued ordinary capital, and the balance forward is slightly higher at £10,755. A final dividend of 17^ per cent, is declared on the £1,200,000, making 25 per cent, for 1937. » » * Short Brothers last week announced an issue of 250,000 re deemable 5 per cent, cumulative preference shares of £1 at par and 50,000 5s. ordinary shares at 27s. 6d. Proceeds will be used to develop the company's business and to replace part of the working capital locked up in the company's holding 0f ordinary shares in Short and Harland, Ltd. » # * Blackburn results for the past year show that, mainly <]ue to the establishment of the Clydeside factory and extensions of the Brough works, issued capital was increased from £630,000 to £800,000, and the fixed assets were nearly doubled—their latest book value is £727,505—while the gross stock and work in progress rose from £548,200 to £1,234,268. After again placing £25,000 to general reserve, the directors are able to raise the ordinary dividend from 12J per cent, to 15 per cent. « * * Handley Page, Ltd., who distributed to shareholders a sub stantial scrip bonus last December, now propose a further capitalisation of reserves. In addition to recommending a final ordinary dividend of 20 per cent., tax free, for 1937, which follows an interim of 10 per cent., less tax, paid in October, the board is to make a bonus issue to ordinary stockholders of one unit for every two now held. This is to raise the issued capital to a figure '' more in accordance with the actual capital employed in and necessary for the require ments of the expansion programme." The company's net profit for 1937 was £210,126, as com pared with £102,679 in 1936.
