Title: Method of and electrical apparatus for sorting granular material according to its moisture content
IPC: B07C5/344
Filed: 1943-12-17
Abstract: 571,791. Determining physical qualities of materials; resistance measurements. OXLEY, T. A., and HENDERSON, F. Y. Dec. 17, 1943, No. 21185. [Class 37] Granular material is sorted according to its moisture content by feeding a stream of granular material of predetermined cross-section, subjecting it to a compressing action to obtain a constant packing factor, and causing the compressed material to pass between electrodes arranged in a circuit so that variation in the moisture content causes the actuation of means by which the material is delivered to a plurality of points according to its moisture content. The spout 3 of a hopper 2 is provided with a slide 4 adapted to regulate the rate at which the granular material is delivered to the surface of a conveying drum 5. This is encircled by a copper or brass plate engaged by a brush 7 connected to an oscillator 8. The drum 5 is secured to a shaft 10 which also carries two grooved pulleys 11, one of which is engaged by a belt 12 driven by a motor 14. The other pulley 11 is connected by a crossed belt 15 with a pulley 16 by which a roller 17 is driven at the same surface speed as the drum. The roller 17 compresses the material issuing from the hopper and supported by the drum while leaving it free laterally in order to obtain a constant packing factor for the granular material, which then passes below an electrode 20. This electrode is connected through a rectifier 22 to an amplifier 23, the output of which is connected to a relay 26 by means of which a hinged flap is moved between two positions so as to direct material from a shoot 43 into one or other of two shoots 44, 44a according to whether its moisture content is above or below a predetermined value. Specification 559,240 is. referred to.

In a frequency-modulation receiver the limiter is arranged to be self-oscillatory in the absence of a signal and produce a control voltage used for muting. As applied to an F.M./A.M. receiver, with switch AM-FM in the F.M. position the A.M. intermediate frequency circuits AM I, AM II are back-coupled over capacitors C1, C2 so that the limiter T1 oscillates at the A.M. intermediate frequency when not biased back by a signal. The oscillations are rectified by the A.M. detector D1 and applied over resistor R4 to control a D.C. amplifier T2 whose collector circuit comprises a diode D2 forming a variable shunt across the discriminator circuit FM II: the switch-off level may be varied by means of resistor R5. A control voltage may also be taken off across resistor R1 and used to control the gain of an I.F. stage, or for other purposes, e.g. in a radio microphone it may be used for switching on a sound tape recorder. In a second embodiment (Fig. 3, not shown) the oscillations at A.M. intermediate frequency are applied to the centre of the F.M. discriminator circuit, so causing high conduction in the diodes which thus provide heavy damping on the circuit. In a modification (Fig. 4, not shown) the A.M. diode detector is biased conductive on F.M. and so damps the circuit AM II when momentarily low signal levels occur, preventing premature muting at such moments.

Title: Improvements in or relating to shoe welt attaching and slashing devices or the like
IPC: A43D44/00
Filed: 1924-09-16
Abstract: 244,513. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Sept. 16, 1924. Cutting. - In a welt-attaching machine provided with welt-slashing means operating on a part only of the welt, mechanism is provided for automatically starting and discontinuing the slashing at a predetermined position, corresponding in practice to the toe of the shoe, the slashing device being placed at some distance from the point of operation of the welt-attaching device. In the arrangement shown, the welt is attached by sewing-devices of known construction controlled through a rod 12. The welt is fed over a roll 14 to a guide 10 through a guide 42 mounted on a slide 18 which is moved upwards at a determined time to bring the welt into the path of a reciprocating knife 16. The knife is mounted on a toothed slide-bar engaged by a toothed segment carried by a lever 22 actuated, through a link 24 and lever 26, by a cam-slot 28. The slide 18 is connected by toggle-levers 60 to a lever 58 connected by a rod 56 to a lever 50 engaging a cam-surface 46. When the elevated part of this cam engages the lever the slide is moved to hold the welt in the path of the knife. The cam is moved from a zero position, to which it is returned by a spring 104 by pawl mechanism co-operating with a mutilated ratchet-wheel 72 adjustably locked to the cam by a spring pin 74. A spring pawl 82 is mounted on a lever 86 carrying a roll which engages the cam-groove 28, the lever being thereby oscillated to feed the ratchet wheel step by step. A lever 90 controlling the pawl 82 overties an arm 94 connected to a stop pawl 98 which normally prevents the backward motion of the ratchet wheel. By varying the relative positions of the ratchet wheel and cam 46 as indicated by a pointer 116 the distance of the first of the slashes from the severed end of the welt is varied so as to adjust the position of the slashed part to coincide with the toe of a shoe in accordance with varying sizes of shoe. After the lever 50 has ridden off the elevated part of the cam 42 the welt-supporting slide moves out of the path of the knife and the cam ceases to move when the pawl reaches the end of the toothed part of the ratchet wheel. At the conclusion of an operation the stop rod 12 acts through a lever 112, 108 to lift a rod 106 which engages the lever 94 and lifts the stop-pawl 98, whereby the cam 42 is allowed to be returned to zero position by its spring. Specification 5453/12 is referred to.
