Abstract: 1,051,365. Railway vehicle undercarriages; mounting axles. BRITISH RAILWAYS BOARD and D. WILLIAMS. April 14, 1965 [April 20, 1964], No. 16236/64. Heading B7L. In a railway vehicle having a live axle mounted directly thereon or on a bogie attached to the vehicle so as to be capable of a limited amount of yawing motion relative to the vehicle frame or bogie the axle 3, Figs. 1 and 2 (not shown) is directly attached to a triangular guiding structure, e.g. 4a, which moves as a unit with the axle in yaw, the apex of the structure lying ahead of the axle in the direction of travel of the vehicle and connected to the vehicle frame or bogie frame by a mounting device which permits stabilizing hydraulically damped relative horizontal transverse movement between the guiding structure and the frame in question. As shown in Fig. 3 the apex of the guiding structure (not shown) is connected by the slotted forks 26, 27 of a member 25 to sliding blocks 28, 29 rotatable on bosses 32, 30 secured on coupling member 20 slidable on bushes 22, 23 on a piston rod 16 extending transversely of the vehicle frame or bogie frame and passing through a guide bush 24 on the frame. The piston rod has a piston 12 movable in an hydraulic cylinder 15 secured to the frame and provided with restricted orifices 13, 14. The member 20 may be operatively secured to the piston rod by moving serrated jaws 18, 19 into engagement with a serrated part 17 of the rod 16. When this is effected the apex of the axle guiding structure will be movable transversely of the frame with damping action. The jaws 18, 19 normally urged away from the part 17 by spring hinge means (not shown) and gravity respectively, are moved into engagement with the part 17 automatically by a slidable ring 33 having pins 35, 36 connected by the forks 37, 38 of a lever connected to internally threaded sleeve 42 engageable with an externally threaded member 40 on the associated axle as described with reference to Fig. 6 (not shown). When the axle is rotated in a direction such that the apex of the axle guiding structure bends the axle in the direction of movement of the vehicle the ring 33 is slid over the jaws 18, 19 and vice versa. Each axle may be provided with guiding structure for each direction of vehicle movement.

Abstract: 1,252,152. Direction finding. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. 16 Oct., 1959 [7 Nov., 1958], No. 35187/59. Heading H4D. A method for the electronic study of signals in the form of random voltages, the energy spectrum of which is limited to a narrow band which is symmetrical with respect to a known frequency, comprises introducing a delay in the amplitude and phase modulations of two voltages obtained from the narrow band and eliminating in these modulations any term proportional to the delay. The method may be applied to locating a source of sound by means of four hydrophones arranged in a line; the difference in phase of the outputs of the centre two hydrophones is measured to give the bearing of the source, and the difference between the differences in phase of the first two and last two is measured to enable the range to be calculated. In Fig. 3 the output of a hydrophone is fed through a line 7 to two mixer circuits 8, 9 where it is heterodyned with carrier voltages sin # 0 t and cos # 0 t respectively from a local oscillator G, # 0  being the mean angular frequency of the signal. The outputs of circuits 8, 9 are fed through variable delay circuits to mixer circuits 12, 13 where they are used to modulate signals sin # 0 t and cos # 0 t respectively. It is shown in the Specification that if the input signal in a (t) sin [# 0 t + #(t)] the sum of the outputs of circuits 12 and 13 is equal to a (t - #) sin [# 0 t + # (t - #)] where a and # are the amplitude and phase functions of the input signals and # is the delay in the delay circuits. The output of an adjacent hydrophone is a (t - 0) sin [# 0 t - # 0 # + # (t - #)] where # is the phase difference, so the phase difference between these two signals, which is measured by a phasemeter 15, is # 0 # + # (t - #) - # (t - #). # is approximately equal to 0 and is adjusted so that the fluctuation remains small.

Abstract: 1,252,196. F.E.T. logic circuits. NORTH AMERICAN ROCKWELL CORP. 5 Nov., 1969 [5 March, 1969], No. 54295/69. Heading H3T. A logic circuit Fig. 2 controlled by a multiphase clock pulse source has a plurality of F.E.T. logic units 21, 22 each performing an individual function such as ABCD and EFGH and each containing a plurality of F.E.T.'s, the units being connected to an output 23 through respective buffer F.E.T. circuits which are either commonly connected to the output 23 (see 24, 25, Fig. 2) or serially connected thereto (72, 73, Fig. 3, not shown). In operation, during the # 2  period F.E.T.'s 35 and 32 forming part of logic unit 21 conduct and cause a capacitor 27 to be negatively charged to the supply voltage -V. A F.E.T. 26 in the buffer circuit 24 is made to conduct by this voltage on C27 and as the # 4+1  signal at its electrode 30 is at earth during the # 2  period a capacitance 2 on the output line is earthed. During the # 3  period the F.E.T. 32 again conducts, F.E.T. 35 being now off, and C27 is discharged to earth only if all the inputs ABCD are negative to connect the now zero level # 1+2  signal at 37 through the series F.E.T.'s receiving ABCD to the point 34. The logic function performed by unit 21 is thus ABCD and this may be extracted if desired by a F.E.T. 38 assuming an inherent capacitance (not shown) between point 34 and earth to be charged similarly to C27. An identical logic unit 22 receiving EFGH performs the logic function giving EFGH on capacitor 51 also connected to the output 23. The output 23 is thus only zero if all A to H are negative, since otherwise either capacitor C27 or C40 could not be discharged and its negative voltage would turn on F.E.T. 26 or 43 and thus connect the output line 23 to the # 4+1  signal which is negative in the # 4+1  period. The output is thus ABCDEFGH. In a modification (Fig. 3, not shown) two logic units (57, 56) each receiving only three inputs (DEF,GHJ) are connected to operate otherwise as in Fig. 1, with the addition of a further similar logic unit (58) receiving three inputs (ABC) and having its buffer F.E.T. (81) connected in series with those of the other two units (85, 90); that is, in place of the # 4+1  signal which is now applied to the new buffer F.E.T. (81). The output function is then ABC (DEFGHJ).

[Also in Division C4] A laser active medium comprises a host material of calcium or strontium fluorophosphate, a lasing ion of holmium or thulium and a chromium sensitizer ion. The sensitizer ion absorbs the radiation from a pumping light source which radiation is not absorbed by the lasing ion and non-radiatively transfers the absorbed energy to the lasing ion to produce population inversion. The chromium ions may be trivalent Cr<SP>3+</SP> or pentavalent Cr<SP>5</SP>+ as (CrO 4 )<SP>-3</SP> or both together, and the lasing ions H o <SP>3+</SP> and Tm+3.

An embodiment comprises R.F. tuned circuit 9, frequency changer 10 and local oscillator 11, I.F. amplifier 12, limiter 13 and discriminator 14 of the integrator type: the R.F. tuned circuit 9 is mis-tuned away from the signal frequency. so that discriminator 14 produces zero D.C. output on noise and a D.C. output voltage U D  on signal. The following audio stage 15 to which discriminator 14 is direct-coupled is then biased to cut off in the absence of a signal, but the D.C. output voltage U D  biases it conductive for a signal. According to the present invention, . R.F. circuit 9 is tuned by means of a varactor diode 6 to which the D.C. output of the discriminator 14 is applied and so biases the diode as to resonate the circuit 9 when a signal is received.
