Apparatus for analysing complex signal waveforms containing characteristic zero crossing distributions, divides the signal spectrum into two or more frequency ranges, differentiates between samples of the waveform falling within the respective frequency ranges, and alters at least one boundary of at least one frequency range according to which sample dominates in the preceding portion of the waveform. As in the parent, the frequency analysis is done by detecting when the intervals between successive zero-crossings lie in ranges t 1 -t 2  and t 2 -t 3 , and which range dominates is detected. A voltage indicating the dominant range is fed back via an integrating capacitor to vary the value of t 2  and/or other boundaries. As a modification, the boundaries "t 2 " of the ranges "t 1 -t 2 " and "t 2 -t 3 " may be variable independently of each other.

Patent GB-522207-A (GB)
Abstract: 522,207. Gyroscopic apparatus. SIEMENS APPARATE UND MASCHINEN GES. Dec. 6, 1938, Nos. 35565, 35566 [Convention dates, Dec. 6, 1937], and 35567, [Convention date, Dec. 29, 1937]. [Class 97 (iii)] The card of a gyroscopic instrument is adapted to be disengaged from a gimbal frame by lifting and angularly adjusted independently of the frame, the disengagement being effected by instantaneous switching means. As shown in Fig. 8, the card 30 of a directional gyroscope normally rests on a conical ring 29 secured to the vertical ring 4 and is connected by struts 37 to a bevel gear wheel 39 the hub 38 of which encircles the upper bearing for the ring 4. The card is lifted and adjusted by manual operation of a plunger 11 carrying a bevel wheel 40 to engage the wheel 39. The operation of the plunger 11 is controlled by instantaneous switching means 34 which comprises two telescopic parts pushed apart by a spring and is pivoted at one end 35 to the casing 36 and engages at the other end a guide 32 fixed to the plunger 11. In a modification, Figs. 1 and 5, the card 7 is in the form of a sphere surrounding the gyroscope and has a flange 42 normally resting on supports 43, 44, attached to the vertical ring 4. The card 7 is centralised at the top by a wire spring 47, 48, which is secured in a channel 45, 46, in the members 43, 44, and engages a channel 49 in the card 7. The latter has at the bottom a hub 8 closely surrounding an enlarged part 50 on the trunnion 5 of the vertical ring. The card is lifted by a lever 19 carrying a V-shaped leaf spring 23 which engages a groove 54 in the hub 8 before the card 7 is raised by the engagement of the edge of an aperture 22 in the lever 19 with the bevelled edge 52 on the hub 8. When the lever 19 is lowered the spring 23, before being drawn out of the groove 54, serves to pull the card 7 down until the spring wire 47, 48 engages the channel 49. The lever 19 is caused to move on its pivot 20 by a tumbler 17, which is instantaneously rocked on its pivot 18 from one extreme position to the other by the telescopic tripping member 14. The latter is operated by an extension 12 of a plunger 11, carrying a wheel 10 to engage the gear 9 on the vertical gimbal ring. Cam surfaces 24, 26, on the extension 12 co-operate with a pin 28 on the lever 19 to assist movement of the latter. Magnetism may be used to strengthen the attachment of the card to the gimbal ring.

Abstract: 1365716 Electrophonic musical instruments SEEBURG CORP OF DELAWARE 15 Nov 1971 [13 Nov 1970] 52966/71 Heading G5J A tonal rythmic accompaniment is provided by a tone generator system which is automatically actuated to produce one of a number of selectable patterns of notes of a scale and controlled by an instrumentalist to select the tonality of the scale. In a first embodiment, the tone generator system comprises nine unijunction oscillators 119-127, Fig. 3, each producing a tone signal having a predetermined relationship to a tonic. The tone signals are connected via a frequency stabilizing flip-flops 145, voicing network 165-169 and sustain keying circuit to a transducer. The keying circuits are actuated in any one of five selectable sequences by pulses applied at 109-117 to sustain capacitors 160 from a logic circuit fed by a pulse generator, Fig. 1 (not shown). To contro the tonality of the notes produced, the instrumentalist closes one of the pedal switches 171- 183, Fig. 4, to apply positive voltage to the base of a corresponding transistor 218 and so short a selected point of the resistor chain 184-197 to ground. This selects the voltage on the base of transistor 223 which controls the voltage applied to the anodes 132 of the unijunction oscillators, Fig. 3. In a second embodiment, Figs. 6-8 (not shown) a single unijunction oscillator is used and the sequence of notes is produced by superimposing on the anode voltage selected by the instrumentalist an automatically selectable voltage in the form of the voltage drop across a number of resistors selected by nine field effect transistors.

Abstract: 1375827 Harvester control RANSOMES SIMS & JEFFERIES Ltd 15 Nov 1971 [6 Nov 1970] 52970/70 Heading A1F [Also in Division G3] An electrical and hydraulic control mechanism on a combine harvester can be set to keep the speed of reel 1 at a constant ratio relative to the speed of ground wheel 3. Electro-mechanical transducers 5, 7, produce electrical signals whose frequencies are proportional, to the speeds of the ground wheel 3 and the reel 1 respectively. In a control unit 9 these signals are converted by electrical circuits (Fig. 2, not shown) to d.c. voltages, which are compared in a comparator (c). The output voltage of the comparator then determines which of two solenoids 11 and 13 in a doubleacting solenoid valve 15 shall be energised. This in turn determines the direction of flow of oil in a hydraulic circuit (Fig. 3, not shown) which includes a ram 17, whose movement affects a variator pulley 23 in the drive mechanism for the reel, and thus adjusts the reel speed. The speed can be set by means of a variable resistor in the control unit 9. Modifications involve the use of a singleacting solenoid valve, or a double-acting solenoid valve having a central "off" position, to produce a "dead band", or a counter circuit in the electrical system.

Abstract: 1417429 Card selector BELL & HOWELL CO 23 Nov 1972 [2 Dec 1971] 54179/72 Heading G4M A random access card selection device is disclosed. Cards (Figs. 5 and 6, not shown), e.g. microfilm, microfiche, of paper, cardboard or plastic are stored in a plurality of cartridges 10, which cartridges may be accessed using a rotary turret or a Ferris wheel type store. Each cartridge has two decks D I , D II , each card having a tab T which lies in a different transverse position within its deck. A panel 15 is shifted so that a scale S I  or S II , representing decks D I , D II , respectively, is visible through an aperture. Then an indicator 33 is set to a scale position representing the desired card, which indicator correspondingly moves a picking head PC, through pulley 37. The cartridge is placed on the panel which actuates a microswitch to cause a motorcontrolled picker 25 to bend down over the cartridge to extract the desired card, which card is selected by the positioning of head PC. After selection, picker 25 is vibrated to dislodge any unwanted cards which have stuck to the desired card. The picker comprises a set of teeth, preferably triangular metal ones, which are loosely supported on an arm. When the picker 25 descends on to the cards an electromagnet is energized which, using a rod arrangement (Figs. 7-12, not shown), compresses the teeth and grips the desired card. The selected card is then raised into a horizontal position for manual removal.
