Abstract: 660,805. Steam engines. TORNAQUINCI, L. DE M., and ANGELINI, O. Aug. 31, 1948, No. 22941/48. Class 122(iii) [Also in Group XXXI] A cylinder of a reciprocating steam engine on a locomotive is provided with a controlling member enabling the cylinder to operate either as a double- or singleacting cylinder, the cylinder always operating in the latter case in the lower phase of rotation of the crank in order to utilize the reaction pressure upon the bottom of the cylinder to assist the locomotive in its movement. As shown, a double-acting steam cylinder is adapted' to be converted into a single-acting cylinder by means of the controlling member 4 disposed between the steam cylinder and a distributing valve, the member being operable by the driver so that for both directions of travel, such being controlled by the usual link motion, the cylinder can operate as double acting on starting and travelling at low speed, and can operate when desired as a single-acting cylinder. The arrangement is such that the reaction thrust on the bottom of the cylinder is only additive to the locomotive's effort. The cylinders may be arranged two on each side, the cylinders of each pair being 180 degrees out of phase with each other to facilitate starting.

Abstract: 778,443. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. Aug. 10, 1955 [Aug. 10, 1954], No. 23110/55. Class 40(7) Relates to a mobile receiver giving an accurate indication of its bearing from a beacon transmitting a directional radiation pattern rotating at a frequency of such that the envelope of the amplitude variation, Fig. 4 A, of the signal received at the receiver comprises a fundamental component 44 of frequency f, the R.F. carrier applied to the beacon directional aerial being modulated by coarse and fine reference pulse signals of recurrence frequencies f and nf synchronized with the rotation. According to the present invention the mobile receiver comprises means for generating a pulse D, Fig. 4, of duration proportional to the bearing # and means for measuring the fractional portion # thereof where # = N 360/n + #, N being an integer less than n. As shown in Fig. 3 the coarse and fine reference pulses, Fig. 4 C, are selected by decoders 33, 34 respectively and the envelope wave output, Fig. 4 A, from detector 37 is converted in circuit 38 to a pulse train of recurrence frequency f, each pulse B, Fig. 4, thereof triggering a bistable multivibrator 36 to initiate the pulse D, Fig. 4, which is termiriated by the succeeding. coarse reference pulse from decoder 33, the duration of pulse D as indicated by meter 39 giving a coarse bearing indication. A bearing pulse from circuit 38 is also applied through a delay circuit 40 to trigger a bistable multivibrator 35 to initiate a pulse E which is terminated by the next succeeding reference pulse from decoder 34 or 33 and the delay 40 is adjusted until the duration of pulse E as indicated by meter 41 is reduced to zero, the resultant delay as indicated by dial 42 giving an accurate indication of #. The invention is described as applied to a system in which n = 9. The beacon, Figs, 1A and 1B comprises a fixed aerial 4 energized from an R.F. source 2 and surrounded by nine parasitic elements 6, 7 mounted on a disc 5 driven by a motor 8 at speed of f = 15 c/s. element 6 being nearer aerial 4 than elements 7 so that the beacon radiation pattern comprises one major lobe and eight minor lobes and the modulation envelope wave, Fig. 4 A, obtained at the mobile receiver comprises a fundamental component 44 and its ninth harmonic 43, the portion of the envelope wave crossing the zero axis being very steep thereby producing a sharply defined bearing pulse B, Fig. 4. The R.F. source is keyed at 16 (1) by a burst of 50 Kc/s pulses from generator 15 each time the major lobe passes through a datum direction, (2) by a burst of 100 Kc/s pulses from generator 18 each time a minor. lobe passesthrough the datum direction and (3) in the intervals between said bursts by 200 Kc/s pulses from 19. The generators 15 and 18 are keyed by pulses from pick-ups 12 and 13 respectively. spaced around a non-magnetic disc 10 driven by the motor 8 and carrying an iron slug 11.

Abstract: 866,866. Measuring and recording aiming errors in firing practice against moving targets. ETABLISSEMENT RIWES. July 6, 1959 [July 7, 1958], No. 23122/59. Class 119. Relates to apparatus for measuring and recording aiming errors in firing practice against moving aerial targets. A target-tracking apparatus, e.g. radar 1 Fig. 1 determines the azimuth A, elevation H and distance D of a target 2, while the gun 3 has aiming elements S for azimuth and E for elevation. These values are fed into an evaluator 4 as electrical transmissions which are converted into mechanical rotations. Cams 6,7 via differentials 8, 9 supply corrections to the values A and H for target drift and firing angle to give corrected values A<SP>1</SP>, H<SP>1</SP>. The evaluater 4 also comprises a recorder 10 having two uniformly moving strips 11, 12 and four recording devices 13 - 16. The devices 14, 16 for the values A<SP>1</SP>, H<SP>1</SP> respectively of the radar apparatus 1 are shifted relatively to the devices 13, 15 for the values S, E of the gun 3 by spindles and nuts 17, 18 by an amount corresponding to the advance of the strips 11, 12 during the time T equal to the time of projectile flight to reach the target over the distance D measured by the radar 1, the time T being derived from a cam 19. The aiming error can be directly read off the recording strips. A strip bearing the records of S and A<SP>1</SP> is shown in Fig. 2. The azimuth error Rs is indicated at any instant t. The corrections for target drift and firing angle can be applied to the aiming elements S and E of the gun 3 instead of to the values A and H of the radar 1. The apparatus can also be used to discover errors in the fire control apparatus of the gun which appear only after transmission to the gun in form of aiming errors.
