Title: Mobile slewing crane with collapsible jib
IPC: B66C23/36
Filed: 1953-08-26
Abstract: 737,302. Cranes with folding jibs. RHEINMETALL-AKT.-GES. Aug. 26, 1953 [Sept. 1, 1952], No. 23619/53. Class 78 (4). The jib of a mobile slewing crane is in sections 5, 6, 7 hinged together at 8, 9 to fold to the position shown in Fig. 5 in which the upper chord of one section, 6, rests on the roof of the cab 4 or on supports, such as rubber cushions on the roof. Each of the sections 5, 6 is of bell-crank formation so that the luffing rope 12 may be connected to one arm and hoisting rope 14 to the other; thus one rope serves for folding the section while the other restrains the movement of the section when it passes its position of balance. When the jib is to be folded it is first lowered to rest on a folding support 13 as shown in Fig. 1, the fastening 10 holding the end section 5 is removed, and this section is turned to the position shown in broken lines in Fig. 1 by the luffing cable 12, the hook 15 on the hoisting cable 14 being connected to a bolt 17 on the section to restrain its movement. The jib is then raised by the luffing cable 12 until it can be supported by a folding support 19 as shown in Fig. 3 when a fastening 11, Fig. 1, is removed and the hook 15 connected to a bolt 21 on the section 6 so that the hoisting cable 14 may control the descent of the section 6 onto the roof of the cab 4 when the luffing cable 12 has pulled the section past its centre of balance. The support 13 is then folded away. Unfolding is effected by the reverse sequence, the luffing cable 12 restraining the unfolding movement.

Title: Apparatus for recording echograms
IPC: G01S15/96
Filed: 1957-07-25
Abstract: 872,134. Echo-sounders; pulse shaping circuits. ATLAS-WERKE A.G. July 25, 1957 [July 28, 1956], No. 23659/57. Classes 40(6) and 40(7) In a pulse-echo sounder producing recordings on electro-sensitive paper a first kind of rectified pulses obtained after limitation of received echoes and a second kind of pulses obtained by differentiation of rectified received echoes are combined and applied to the recorder, and the limiting level is such that the first kind of pulses use up only part of the response capacity of the paper. Fish near the sea bed are thereby distinguished. In the first embodiment the output of receiving transducer 1, Fig. 2, is fed via amplifier 3, exponential potentiometer 4 and amplifier 5 to demodulator 6 and appears after filtering as amplified negative pulses at the control grid of limiter valve 11. The voltage across resistor 18 when valve 15 is quiescent is below that which produces a recording. Rectifier 14 prevents the valve grid from going negative. A pre-set tap on exponential potentiometer 8 provides an input to a second channel II which provides an output positive pulse by differentiation of the input signal due to capacitor 24 the associated timeconstant being low compared with the input signal rise time, and diode 27 prevents negativegoing channel output pulses. Alternatively differentiation may be effected by feeding the pulse through a delay line the output from which is subtracted from the non-delayed pulse. The output amplitude from limiter 11 is arranged to produce a grey recording the shade of which is adjustable by resistor 12. It is stated that once potentiometer 8 has been set to intensify the recording to black, re-setting is unnecessary on variation of sensitivity potentiometer 4. Channel II output may be limited before combination with that of channel I. The shade of recording obtained from a typical received echo is illustrated, Figs. 3 and 6 (not shown) and the effect of potentiometer 8 adjustment is illustrated, Figs. 7 and 8 (not shown). The signal in channel I may be compressed logarithmically before or after limiting takes place; the nature of the ensuing recording is illustrated, Fig. 9 (not shown). In a further circuit arrangement Fig. 12 differentiation is effected on the limited pulses. Amplifier 34 output is logarithmically compressed by resistor 35 and rectifiers 36. The compressed R.F. pulses are limited by valve 37 the output of which is rectified and supplied to circuit 40, 41, 42 in which differentiation ensues. Limiting may be arranged after rectification. In a modification of circuit 40 . . . 42 the negative swing of the differentiation process is suppressed, Fig. 13 (not shown).

Title: Improvements relating to vacuum brake apparatus for railway vehicles
Inventor: MARSH GERALD CRANTON
IPC: B60T13/46
Filed: 1955-08-19
Abstract: 790,657. Vacuum brakes. GRESHAM & CRAVEN, Ltd. July 25, 1956 [Aug. 19, 1955], No. 23927/55. Class 103 (1). In vacuum brake apparatus for railway vehicles, an automatic isolating valve is con-. nected between the high vacuun chamber and the exhauster and automatic feed valve and acts to close the connection during a brake release operation when the vacuum in the high vacuum chamber is below a predetermined value, but opens the connection when the vacuum in the train pipe of the brake system exceeds the predetermined maximum at which the automatic feed valve closes. In the embodiment illustrated, wherein Fig. 1 shows the " running position, Fig. 2 the " brake applied" position, and Fig. 3 the " brake release "position, the brake system comprises an exhauster a, a non-return valve b, an automatic feed valve c which closes to cut exhauster a off from train pipe d when the vacuum in the train pipe is higher than a predetermined amount (e.g. 21 inches of mercury), a high vacuum chamber e, and an automatic isolating valve f which cuts off communication with the high vacuum chamber e under certain conditions. In the " running " position shown in Fig. 1, the control valve i allows the exhauster to exhaust train pipe d and maintain the brake pistons in their " brake off " position and when the vacuum at the driver's control valve side of valve c is sufficiently high (21 inches of-mercury) the valve will be closed and the exhauster will be concentrated on the isolating valve f and the high vacuum chamber e; the valve element p of the isolating valve being held open by the vacuum in chamber e acting on diaphragm rand by vacuum at s acting on valve element p. When the brakes are applied, as shown in Fig. 2, by movement of driver's brake control valve i to allow air to pass into train pipe d the feed valve c still remains closed and the isolating valve f remains open. In the quick brake release position shown in Fig. 3 the driver's brake control valve i puts feed valve c in communication with the train pipe d to open valve c and allow air to pass to the exhauster and also to chamber e. The combined action of the exhauster a and high vacuum chamber e gives quick release. Should the valve in the high vacuum chamber be reduced below a predetermined level (e.g. 19 inches of mercury) the valve element p is allowed to close, thus preventing the vacuum in the chamber e from falling below a useful value (for example 19 inches of mercury) particularly when several brake applications and releases are made in quick succession without allowing time for the necessary re-charging of the high vacuum chamber e to give quick brake releases.
