Title: Improvements in or relating to apparatus for measuring the moisture content of materials
IPC: G01N27/22
Filed: 1965-07-02
Abstract: 1,117,683. Measuring moisture content. WEYERHAEUSER CO. July 2, 1965 [July 3, 1964], No. 28131/65. Heading G1N. The conductivity, representing moisture content of, for example timber 5, Fig. 1, and Fig. 2 (not shown) is measured by two or more pairs of electrodes 17, 18 and 27, 28, and 37, 38, mounted on a line transverse to the direction of motion of the timber, the electrodes of any one pair being connected together, the electrodes of adjacent pairs being energized by A.C. signals differing in phase by 180 degrees, and the timber itself forming effectively an earthed electrode which with each of the said pairs of electrodes constitutes a capacitance. Each such capacitance is connected in a respective bridge circuit forming part of the overall measuring circuit Figs. 5, 6 (not shown). The electrodes-timber capacitance is represented as a capacitor (C10) in series with a resistance (R10; or C20, R20, C30, R30), the value of the resistance depending upon the moisture content. One end of a centre tapped transformer secondary winding (52) is connected via a standard capacitor C s  to the electrode capacitance C10 - R10, across which a further capacitance C t 10 is also effective due to the earthed shields 11, 12 forming part of the electrode construction of Figs. 1, 2. The earthed end of the electrode capacitance C10, R10 is connected via a variable capacitor Vc - 10 and a further standard capacitor C s  to the same end (Fig. 5) or the other end (Fig. 6) of the secondary winding. A difference in voltage between the points 10a, 10b at the sides of the capacitors Cs remote from the secondary winding, is detected and amplified (at 10b-10a) and represents moisture content. The other electrode capacitances are also connected to the secondary in similar fashion, but are arranged so that adjacent ones are 180 degrees out of phase. The various outputs are fed to a control unit 50 which detects the maximum, minimum, or average moisture content, and may control an ink marking device 45, or operate any other alarm.

Title: Improvements relating to electronic limiting circuits
Inventor: HANKINS HAROLD CHARLES ARTHUR
IPC: H04N5/16
Filed: 1960-08-16
Abstract: 917,599. Limiting and gating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 26, 1961 [Aug. 16, 1960], No. 28309/60. Class 40 (6). A limiter circuit comprises an input branch including a diode D1 and resistance RU1, i.e. the internal resistance of signal source e, and an output branch also including a similarly poled diode D3 and resistance R2, connected in parallel to a high-impedance current source, i.e. resistance R1. The resistance R2 is shunted by a diode D4 which is normally biased non- conductive. The arrangement is such that in the non-limiting condition the current through resistance R1 divides between the two branches ; when the limiting level is reached, however diode D4 becomes conductive and substantially all the current flows via diodes D3, D4, cutting- off the diode D1. The resistance R1 may be replaced by a transistor acting as a constant current device. The arrangement may in addition be used as a gating circuit for selecting signal pulses, gating impulses being applied via a resistor R3 to a diode D2 connected to the junction of diodes Dl, D3 and causing this junction to be earthed whenever a gating impulse is applied. Gating impulses may alternatively be applied to the diode D4, so causing this diode to earth the output of the arrangement whenever a gating impulse is applied.

Patent GB-508755-A (GB)
Title: Improvements in seed sowing apparatus
IPC: A01C7/18
Filed: 1938-09-30
Abstract: 508,755. Distributers for seeds. BEEMER, E. A. W. Sept. 30, 1938, No. 28523. [Class 6 (i)] A seed distributer is provided with a reservoir which rotates as the distributer moves along the ground, the seeds being lifted from the bottom to the top and falling in a stream within the reservoir. Adjustable means are provided for dividing the falling stream into two parts, one being led to the furrow in the ground and the remainder falling back into the reservoir. The adjustable means may be moved continuously to open and close the seed exit and thus cause the seeds to be sown at intervals. Fig. 1 shows the implement having a hollow seed reservoir 2 which has an opening in one side closed by a stationary plate 3 as shown in Fig. 9. The plate 3 forms a part of the frame 1 of the implement and supports various members within the reservoir which do not rotate therewith. The reservoir is provided inside with flights 7 which lift the seeds and drop them in a stream down a fixed spout 8 beneath which is a movable tube 11 leading to a fixed tube 9 which conducts the seeds to the ground. The position of the tube 11 determines the proportion of seeds delivered to the tube 9. The tube 11 is rigidly secured to a shaft 12 which is journalled in the plate 3 and can be rotated to move the upper end of the tube 11 relatively to the spout 8. The extent to which the shaft 12 can be rotated is determined by an arm 13 fixed to the shaft 12 and provided with a projection 16 extending into a slot 15 in a plate 14 pivoted on the shaft 12. The end of the slot 15 forms a stop for the projection 16. The position of the plate 14 can be varied by a link 17 connected to a screw 18 carrying a nut 19. Rotation of the shaft 12 is produced by an arm 22 fast on the Shaft and connected by a bent spring 40 to an arm 25 pivoted to a fixed frame 24. The arm 25 carries a member 26 which is rocked periodically by engagement with a series of pins 27 which project through one side of the reservoir 2. The rocking movement of the member 26 is transferred through the arm 25 and spring 40 to the shaft 12. The pins 27 have a part of their inner ends cut away as shown at 30 in Fig. 10 so that by turning the pins half way round they no longer engage the member 26 and the distance between the seeds delivered to the tube 9 can thus be varied. To sow a continuous row of seeds, the shaft 12 is fixed with the arm 13 and its projection 16 at the end of the slot 15. The arm 13 is fixed by a pin 42 mounted eccentrically on a disc rotatably mounted on the plate 14. The implement shown in Fig. 1 is provided with a furrow opener 33 and furrow closer 34 and a wheel 35 for compacting the earth of the closed furrow.
