In a construction of casting mould, Figs. 1, 3 and 4 (not shown), the mould cavity (22) is formed by side members (14), end members (34), (36) and top and bottom members (32) and (30) respectively. The side members 14 are formed by a plurality of abutting block sections (14a), (14b) &c., clamped together in a frame formed by ties (54) and end members (50), (52), which together constitute side units (10). The end members also incorporate clamping means in the form of screw jacks (68) and hydraulic jacks (74). The screw jacks (68) which are non-yielding are used primarily for clamping the blocks to facilitate transportation of the unit (10) and during any machining of the block face (20) to remove irregularities. The hydraulic jacks effect a yieldable clamping action to compensate for expansion of the side units during casting operations. In an alternative embodiment, spring means in co-operation with the screw jacks are provided to effect positive but yieldable clamping of the blocks. The complete mould is mounted on a movable platform (16) and is bottom poured through a pouring tube (41). The blocks (14a) and (14b) are made of graphite.

Abstract: 1400008 Radio navigation; aerials MARCONI CO Ltd 11 Oct 1972 [8 Oct 1971] 46993/71 Headings H4D and H4A In a microwave beacon a linear array of radiators is fed each with a similar frequencymodulated (F.M.) carrier, the frequency modulations being time-delayed inter se such that the frequency of radiation is direction-dependent. The F.M. may be sawtooth. The invention is applied to aircraft landing, both for azimuth and elevation, with different carrier frequencies. In an embodiment the amplitude of the signal radiated by each aerial is sampled, the sample compared with a signal representing desired amplitude, and the comparison is utilized to maintain constant radiated amplitude. Where the microwave carrier is routed from a central generator, phase thereof is controlled to reduce any difference at the aerials. To reduce sidelobes an amplitude taper is imposed. Typically there are 100 radiators. An unmodulated carrier may be radiated additionally and omnidirectionally to afford a frequency reference for the aircraft receiver.

[Also in Division G3] The feed of the tool electrode in an electroerosive machine is controlled by comparing the number of control pulses in a given time interval with the number of discharge pulses and converting deviations from a predetermined desired value into directional signals for the feed drive; thus, if optimum conditions require 200 control pulses and 180 discharge pulses per unit of time, then 170 discharge pulses to 200 control pulses will produce a signal to reduce the discharge gap, whilst 190 discharge pulses to 200 control pulses will cause an increase in the discharge gap. Suitable circuits to effect the desired control are described with reference to Figs. 1 and 2 (not shown), the control and discharge pulses being detected by counters the outputs from which are applied over an analysing circuit, including resetting means for the counters, AND gates and a bistable multivibrator, which produces the control signal for the electrode feed mechanism.

Abstract: 1345062 Inverting WESTINGHOUSE ELECTRIC CORP 13 Oct 1971 [26 Oct 1970] 47623/71 Heading H2F [Also in Division H1] In an inverter of the type in which each halfcycle of the output involves multiple discrete cycles of switching means Q1 ... Q4, magnetic sensing means M is provided to detect magnetic flux unbalance in the output transformer T during alternate half cycles of the output and an indicator 70 or correction circuit 60 responsive to the output of the magnetic sensing means M. Fig. 1 shows an inverter of the type described in Specification 1,334,179, in which pairs of transistors Q1, Q4 and Q2, Q3 are turned on alternately by means of a control circuit 20, so as to provide a pulse-width modulated wave E out  corresponding to a reference sine wave. Harmonies are removed by L1, C1. In the event of flux unbalance in the core of output transformer T, i.e. if saturation is impending, the flux in the stepped gap increases so that a signal (Fig. 2, not shown) is induced in winding W, during a zero crossing of the output waveform, the direction of the zero crossing during which the signal occurs being indicative of the direction of flux unbalance. A synchronous demodulator 60, switched by a quadrature square wave from 62, provides a D.C. control voltage for the control circuit 20 so as to correct flux balance. Alternatively, a shell type output transformer T (Fig. 5, not shown) may be used having saturation detecting windings on the outer limbs. The invention prevents damage due to current being switched into a saturated output transformer.

Abstract: 1338470 Fire alarms; selective signalling PREUSSAG AG FEUERSCHUTZ 14 Oct 1971 [21 Oct 1970 (2)] 47859/71 Headings G4N and G4H In a fire alarm system utilizing variable impedence fire detectors connected in parallel across a line connected to a central station, the line current is repetitively interrupted, each interruption being initiated by a change in line current at least as great as that caused by one detector responding to a fire. A fire alarm is initiated only if, immediately after at least the majority of such interruptions the line current returns to a value which is at least as great as the change which occurs when one detector responds to a fire. False alarms are thereby minimized. As shown in Fig. 2, the current through a plurality of fire detectors (not shown) connected in parallel to a line 11, is monitored by an amplifier 14. The current is normally zero, but increases in the event of a fire. If the increase is sufficient, the output of amplifier 14 triggers a 5 ms monostable A1, the trailing edge of the output of which successively trigger an 80 ms monostable A2 and a 30 ms monostable A3. The line current is interrupted by switch 15 for the duration of the pulse from A3. Monostable A1 is inhibited by a memory 17 for the duration of monostables A1 ... A3 to prevent operation by spurious pulses. If the current in line 11 is still indicative of a fire, the above sequence is repeated. Each pulse from A1 steps a counter 16 and starts a slow timer A4, which re-sets the counter 16. An alarm is initiated after counter 16 has stepped to a predetermined count. Fig. 8 shows a system that avoids false alarms due to short circuits. The line current for amplifier 14 is differentiated at 211 and compared with a reference 231. If di/dt is within a given range, timers 38 and 39 are initiated to interrupt the line current at 15 and thus step a counter 37. If di/dt is excessive, an output at 36 re-sets the counter 37. Local fire detectors.-Figs. 5 and 6 (not shown) depict detectors which provide output signals on line 11 having a discrete rise time by the use of CR circuits in the input line of a switching transistor or output line of a thyristor, turned on in the event of fire. A Zener diode may also be used to shape the leading edge. Signalling location of fire.-Each local fire detector (as referred to above) may provide a fire-responsive signal having a different rise time. In Fig. 9 (not shown) the line current at the central station is differentiated and fed to a group of comparators respectively responsive to signals having rise times corresponding to those of the local detectors.
