The carrier frequency of a frequency modulated oscillator (12, Fig. 1, not shown), is controlled by mixing the output of the oscillator with the frequency-multiplied output of a crystal oscillator (18) the output of the mixer (17) being nominally the same frequency as the output of a second crystal oscillator (15) and the two outputs being switched alternately to a discriminator (22) which produces a control voltage for controlling the frequency of the oscillator (12).

Title: Analog data accumulator

Abstract: 1,247,932. Analogue data accumulation. HITACHI Ltd. 27 Sept., 1968 [29 Sept., 1967] No. 46145/68. Heading G4G. [Also in Division G1] Analogue data accumulator for improvement of S/N ratio of signals derived, e.g. from spectrophotometers, mass spectrometers gyrometic resonant apparatus, encephalographs, and the like comprises (Fig. 1) analogue data signal source 1 connected to three-input adder 3 connected over low pass filter 4 to changeover switch 6 and 4 channel tape recorder 5; wherein the output of filter 4 and a sync. signal applied to source 1 are recordable on channels A, B or C, D, while corresponding signals are reproduced from channels C, D or A, B respectively. The respective reproduced signals are applicable over inverter 7 to recorder 10 and an input of adder 3, and over shaping circuit 8 to synchronize data source 1 and to energize recording channel B (or D) while also applied over LP filter 9 to the remaining input of adder 3. An electronic circuit (Fig. 3, not shown) comprises inverter 7, adder 3, LPF9, and LPF4; interconnected with appropriate inputs and outputs. In operation, first analogue data are coupled through LPF2 to adder 3 and LPF4 with changeover switch in solid line position, so that the output of LPF4 is stored in channel A and a synchronization pulse in channel B. On completion of storage, switch 6 is changed over by a completion signal from a source (not shown) so that channel B signal is reproduced and shaped at 8 to trigger source 1 to derive a second analogue data signal fed to adder 3, while the sync. signal is stored in channel D. The first analogue data signal is reproduced from channel A, inverted at 7 and fed into adder 3 for combination with the second analogue data signal, filtration at 4, and recording in channel C. Switch 6 is restored by a completion signal and the stored sync pulse is reproduced and shaped at 8 to once more trigger the analogue data source 1 to deliver a third analogue data signal over filter 2, while the sync. signal is stored in channel B. The analogue data signal stored in channel C is reproduced, inverted, and fed to adder 3 for recombination with the third data signal and recording in channel A. The operation is repeated as often as necessary to accumulate successive analogue data signals, which are finally recorded at 10; the signal/noise ratio being increased by factor #N where N is the number of accumulations. Noise perturbations from the recorder are removed by derivation of noise signals together with sync signals from channels D or B in the respective states of switch 6, extraction by LPF9, and subtraction from the input of adder 3 and recorder 10. In a modification (Fig. 2, not shown) two tape recorders utilizing each two channels are employed; one channel in each recorder being employed for reproducing, erasing, and storing analogue data and the other for reproducing, erasing, and storing sync. signals. Figs. 4a to 4d (not shown) illustrate progressive data accumulation and reduction of S/N ratio.

A rake-wheel type haymaking machine comprises a main frame-member 82 with rake-wheel-carrying beams 91, 92, 93 mounted on each side of it, the beams 91, 93 on opposite sides of the frame-member being connected to it and to each other by interconnected pivoted links 94 which enable the beams to move bodily about the axis of the member 82 against the loading of springs 112. The frame-member is extended by a cranked portion 84 so that it is shaped as a figure-7 in plan and is supported by a castor-wheel 86, 89 at each corner, the castor 89 at the end of the cranked portion being united with a drawbar 128 and the other castors having lockable swivel-axes. Each beam 92, 93 has two integral stub-shafts 98 terminating in vertical bearings 99 which receive the cranked ends of axles carrying the rakewheels 107. The beam 91 has similar stub-shafts 108 which receive the rakewheels removed from the beam 93, for swath-turning. For tedding, all the rakewheels are carried by the beams 92, 93 but the rake-wheel planes are swung into the dotted positions. The links 94 are pivoted to lugs 96 carried by the member 82 and are connected together by a pin and slot 113, 114 so as to rise and fall together under the action of a pivoted lever 115 terminating in a cross-piece 119 underlying the links 94 attached to the beams 92, 93, the lever being operable remotely, through a cable 121. In a modification (Fig. 8, not shown) the arms 108 do not terminate in bearings but have horizontal bores to receive the ends of straight stub-axles which can carry the removed rake-wheels. In this construction the lifting lever is arranged to pass over-centre so that the system is self-sustaining with the beams either in a raised or a lowered position, the latter being adjustable by a screw-threaded stop on the frame-member.
