Abstract: 1,249,462. Controlling. JOHN FORMBY & CO. Ltd. 28 Oct., 1968 [2 Aug., 1967], No. 35410/67. Heading B8A. [Also in Division H1] A control apparatus for initiating an operation at a particular phase of a cycle of movement of a mechanism, comprising a plurality of trains of rotary members (as shown, gear trains 5, 10; 3, 8; and 4, 12, 14) having a common drive means 2, means 15a, 15b, 15c borne on the driven rotary members to operate switching means (16a, 16b, 16c) at predetermined orientations of the rotary members, the latter repeating periodically, but only at the same instant, in respect of all the trains, once during the cycle of the mechanism, i.e. at the particular phase of the cycle, means then being operated to provide an electrical control signal O/P. Instead of micro switches, a disc 45 (Fig. 4) of plastics material may be carried by each driven gear wheel. This is fitted with a metal insert disc 49 which coacts with an oscillator 51 to produce a signal at the predetermined orientation. When the three output signals occur simultaneously they trigger an " AND " gate 53 to produce the signal O/P. In a further modification (Fig. 5, not shown), a light (56) shines through apertures (44b) and (45b) in discs (45a) and (44a), to activate a photo-electric device (54). The apertures (44b) and (45b) are in alignment only at the instant corresponding to the particular phase of the chain 17. A composite apparatus may provide a series of output signals by having a series of gear trains and associated sets of micro switches (Fig. 2, not shown). In another application (Fig. 7, not shown) the drive shafts 2 of a series of the apparatuses are coupled together by mechanical gearing or by Selsyn transmitters. In Fig. 6, in an article delivery system arranged in a three storey building, a fixed delivery box 58a has an article delivery shoot 61a controlled by a solenoid 63a. The latter is activated by an apparatus 57a which has its shaft 2 (Fig. 1) coupled to the drive of the conveyer chain 17. As shown, the solenoid 63a has previously been energized to cause the box 58a to discharge into a conveyer carrier 59a. The latter is suspended from the chain 17, has ground engaging wheels 69 and has a discharge device 64a which is adapted to be activated by a solenoid 66a energized at the due time by a signal from an apparatus 57c. Thereby the carrier 59a discharges its load into a collecting box 60a. Similarly a carrier 59b loaded from a box 58b delivers its load to a box 60b on the second floor of the building.

Abstract: 367,471. Moulding heat-evolving cartridges. MELLGREN, N. L., 5A, Vasagatan, Gothenburg, Sweden. Nov. 25, 1930, No. 35488. [Class 87 (ii).] In the manufacture of heat-evolving cartridges having a central cavity 20, Fig. 4, for a priming composition, a moulding machine is employed which leaves the mixture 23 below the cavity in a less compressed and more easily ignited condition than the remainder 24. The moulding machine is provided with a rotating shaft 2 carrying two discs 5, 6 with cam grooves 7, 8. The cartridge casing 12 is placed on the table 9, and the central plunger 19 lowered into it by the engagement of its projecting head 17 with the cam groove 8. The mixture is then filled in, and the shaft 2 rotated to cause the annular plunger 16 to descend by engagement of its head 13 with the cam groove 7, and thus to compress the mixture. The annular plunger is then withdrawn, followed by the central plunger, so that the portion 23 of the mixture remains in a somewhat softer condition than the remainder. Specifications 1745/15 and 186,617, [both in Class 64 (ii), Heating systems &c.], are referred to.

Abstract: 995,113. Frequency modulation. MARCONI CO. Ltd. Sept. 27, 1963 [Sept. 11, 1963], No. 35849/63. Drawings to Specification. Heading H3R. A phase shift oscillator comprises two grounded grid phase shifting valves in cascade connected through a third and amplifier valve to the cathode of the first valve, modulation being applied to the grids of the first two valves to vary their Gm and phase shift and produce frequency modulation of the generated frequency f (proportional to Gm). By selecting the grid biases any non-linear variation of Gm (and f) may be made symmetrical about the grid biases, to eliminate second order modulation distortion. Further, a tunable resonant circuit shunted by resistance shunts the anode circuit of the third valve to produce a parabolic phase-shift frequency characteristic which compensates any third order distortion of the frequency modulation. A rectifier across the grid circuit of the third valve causes it also to act as an amplitude limiter. Any amplitude modulation of the oscillator by the third valve may subsequently be eliminated without group delay variation. Second order distortions due to valve circuit and transit times may be reduced by off-setting the modulator operating conditions or tuning of the resonant circuit.

[Also in Group XL (c)] A balanced microwave frequency-changer comprises a pair of rectifiers symmetrically disposed in a waveguide and fed with a symmetrical wave from the first source and a non- symmetrical wave from the second. In one embodiment two crystal rectifiers 11, 12, Fig. 1, are located side by side across a waveguide 10, to the end 21 of which is applied a signal wave of TE 10  mode : the guide is tuned by means of a screw 13. The wave is converted to the TD 20  mode by means of a plate 14 screening half the waveguide and the TE 10  mode is suppressed by means of a plate 15 arranged along the longitudinal axis. The other end of the waveguide is closed by a sliding plunger 16, and the local oscillator energy is introduced as a wave of TE 10  mode by means of a coaxial cable 17. An iris diaphragm 18 is interposed in the path to the rectifiers 11, 12 while the space between the plates 14, 18 is filled with a dielectric material. In a second embodiment, the rectifiers 11, 12, Fig. 2, are symmetrically located in a cavity 20 and fed with local oscillations 171 in TE 10  mode introduced by means of a coaxial cable 17. The signal wave is introduced in TE 10  mode 211 at a suitably dimensioned opening 21; the cavity 20, however, is dimensioned and the projecting portion # so adjusted-a movable piston may be provided-as to transform this wave to the TE 20  mode 212. In a further embodiment (Fig. 3, not shown) the oscillator energy is introduced into the waveguide via a single coaxial cable, while the signal is fed in at spaced points over a branched cable, the two branches of which differ in path length by half a wavelength at the signal frequency.
