Title: Mechanism for the automatical regulation of the braking force of compressed air brakes for railway cars to prevent the slipping of the braked wheels on the rails
IPC: B60T8/32
Filed: 1924-02-25
Abstract: 225,099. M³ller, H. Feb. 25, 1924. Fluid-pressure. - In compressedair brakes automatic means for regulating the pressure in the brake cylinder to prevent skidding of the wheels comprises a balance piston valve z, connected to the brake cylinder t by a pipe u, the movement of which is controlled by a ring i frictionally engaging an extension h of a ring d which rotates with the axle wheel a. The ring d is connected by sliding bolts f and springs g to a flange c keyed to the axle a, whilst the ring i is in two halves which are pressed together by springs j on bolts k. When the axle is stationary, the parts take up the position shown, so that the brake cylinder is connected to exhaust through the ports r, q, but when the axle is rotated, the ring d carries the ring i with it until the arm l, acting on the valve piston, has moved it to one or other of its end positions, when further movement of the ring i is prevented. The port q is now cut off from the brake cylinder exhaust r by one or other of the packing-rings p, p<1>. If skidding occurs and the axle a ceases to rotate, the ring d will continue to rotate through a small arc by reason of its inertia, thus compressing one of the springs g. When it comes to rest, the spring g will return it to its mid-position, and it will now carry with it the ring i, thereby moving the slide valve z to the exhaust position. As soon as the axle begins to rotate again, the ring i is moved to cut off communication between the ports q, r.

Title: Improvements in or relating to frequency-stabilized oscillators
IPC: H03B5/34
Filed: 1953-02-26
Abstract: 725,325. Valve generating circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 26, 1953 [March 1, 1952], No. 5403/53. Class 40 (6). The invention relates to oscillators of the type comprising an oscillator valve having a first positive feed-back path for producing oscillation and a second positive feed-back path including an auxiliary amplifier valve and a highly selective circuit for stabilising the oscillation frequency. According to the invention the outputs of the two feed-back paths are connected in series in the grid-cathode circuit of the oscillator valve and the grid-cathode input impedance of the valve exceeds the load impedance as seen from the grid cathode circuit. The frequency of the high power diathermy oscillator 1, 2, 3 (Fig. 2), is stabilized by a feedback path comprising valves 6 and 7 and a crystal 8, the output of valve 7 being supplied in series with the main feed-back connection to the grid since series feed requires less power than the previous parallel feed arrangement (Fig. 1, not shown). Valve 6 may change the frequency of the oscillators to a value more convenient for the operation of the crystal and the local oscillator used for the first frequency change may be applied to the second valve 7 to reproduce the incoming frequency (Fig. 4, not shown). In Fig. 3 the main oscillator 3 is of the Colpitts form, the frequency controlling feed-back being applied to the grid.

In an apparatus for jamming radio signals a panoramic receiver 2 including a frequencyswept oscillator 5 scans the required frequency band, any received signal, up to a maximum number as determined by a counter (not shown) operating on the A.G.C. circuit, producing an output from mixer 3 which is supplied to a control circuit 4. The device 4 stops the oscillator 5 for a short period, de-sensitizes the receiver 2 and operates the transmitter 6 to which the output of the oscillator 5 is fed after frequency conversion, whereby the appropriate jamming signal consisting of a noise-modulated carrier wave is transmitted from aerial 7. Certain carrier frequencies within the band may be excluded from jamming as by arranging that the receiver is de-sensitized at these frequencies. The scanning frequency may be fixed or variable. The effect of varying the scanning frequency and/or the duration of jamming in each cycle is discussed.
