Abstract: 829,404. Loading machines. SAARBERGWERKE. March 23, 1956 [May 20, 1955], No. 9121/56. Class 78 (1). A loading machine for loading cut coal on to a face conveyer comprises a longitudinally shiftable frame which is moved intermittently parallel to the face, a collecting head mounted on a pivotal connection for pivotal movement about a vertical axis for sweeping the area to be cleared and also a horizontal axis for enabling the collecting head to follow the ground, the pivoted connection being longitudinally slidable relative to the frame to enable the collecting head to remain stationary whilst the frame is shifted, and vice-versa, and a transverse loading arm for receiving the coal from the collecting head and delivering it to the conveyer. As shown, the frame 1 comprises a slideway 5 for the pivotal connection 4 of the collecting head 2, the connection 4 comprising a vertical pivot carried by a member 19 in turn mounted on a horizontal pivot carried by a carriage slidable in the slideway 5. The frame is mounted on skids, and the collecting head is also mounted on skids 20, 21, 22. Alternate shifting movements of the frame and collecting head are effected by a pair of hydraulic cylinders 23, whose piston-rods 24 are pivoted to the member 19 below the horizontal pivot on which it is mounted. The collecting head 2 comprises primary and secondary sets of endless scraper chains 3 and 8 respectively which deliver the coal rearwards to an endless scraper chain 17 running around a guide member 18 on the loading arm 9. The frame 14 is slidably mounted at 15 on the frame 1 so that it can be extended by an hydraulic cylinder 16 between two adjacent pit-props 11 for loading the face conveyer 10, and be retracted when the frame 1 is to be shifted. The secondary pusher chains 8 are mounted on an arm 6 pivoted at 7 on a vertical axis to the collecting head 2, so that when the frame 1 is advanced relatively to the collecting head, Fig. 3, the arm 6 can be swung forwards out of the way by an hydraulic cylinder acting on the arm through rack and pinion mechanism 46, 47, and when the collecting head is pushed forwards relatively to the frame 1 to sweep a fresh area of cut coal, Fig. 4, the arm 6 can be swung into its operative position where chains 8 transfer the coal from the chains 3 to the chain 17. The chains 3 are superposed and comprise six chains 33-38, Fig. 6b. Chains 8 are represented in Fig. 6b by a single chain 40. All the chains 33-38 and 40 are driven from a common motor 39 through bevel gearing.

Title: Improvements in or relating to methods of and means for neutralizing capacity coupling between electric circuits
IPC: H03F1/16
Filed: 1923-04-05
Abstract: 222,894. Jackson, W. J. Mellersh-, (Independent Radio Manufacturers, Inc.). April 5, 1923. Coupling aerial and detector circuits; undesired signals, eliminating or limiting. - Undesired capacity coupling between two circuits is eliminated by the provision of a coil which is closely coupled to a coil in the first circuit and is connected through a capacity to the second circuit. As shown in Fig. 1, the first circuit A has a connection to the second circuit B through impedances Z<1>, Z<11>. The capacity between the circuits is represented by condensers C<1>, C<3>, and is neutralized by the addition of a coil L<2> and two capacities C<2>, C<4> connected as shown. The coil L<2> is closely coupled to a coil L<1> which may form part of the circuit A or may be an additional coil connected across that circuit. The capacity ratios C<1>, C<2> and C<3>, C<4> are made equal to each other, and to the inverse ratio N<2>, N<1> of the number of turns in the coils L<1>. L<2>. Any alternating or oscillatory current from B and transferred to L<1> and A on account, of the capacities C<1>, C<3>, is accompanied by a corresponding transfer through C<2>, C<4>, L<2>. On account of the electrical proportions mentioned above, the fluxes in the coils L<1> L<2> neutralize each other, so that no effect is produced on the circuit A. Fig. 3 shows the application of the principle to the prevention of capacity coupling between two coils such as the aerial coil 7 and secondary coils L<1> of a wireless receiver, and Fig. 5 shows a construction of variable coupler. The capacity between the two coils is represented in Fig. 3 by the condensers C<1>, C<3> having a common point 13 at one end of the coil L', the other end being earthed. The balancing capacities, represented as C<2>, C<4>, are obtained by winding a coil L<2> in reverse direction over the coil L<1>, the number of turns being determined by trial. One end of the coil L<2> is earthed, and the other end is free. This free end may be extended by a straight wire lying adjacent to the lead 13a. The three coils are enclosed in a box 2 with an earthed metal lining, and the remainder of the receiver circuit is enclosed in a separate compartment 3. The movable elements of the tuning condensers 9, 17 are connected to earth. In Fig. 5, the secondary coil L<1> and the superposed balancing coil L<2> are wound on a former 25 which can be turned on a spindle 26 by a knob 27. The aerial coil 7 is secured by brackets 23, 24 to a panel 22. The coil L<2>, apart from its balancing effect. acts to some extent as an electrostatic shield between the coils 7, L<1> and so reduces the electrostatic coupling between these coils. This effect may be increased by winding a third coil within the coil L<1>. The invention may also be applied to the neutralization of internal capacity coupling in a valve, but this is described in detail in Specification 222,895. Reference has been directed by the Comptroller to Specification 119,365.

Abstract: 706,036. Producing nuclear reactions. Magnetic induction accelerators. PUYMORIN, R. A., D'A. DE. April 23, 1951 [April 24, 1950], No. 9415/51 Classes 39(1) and 39(4) Nuclear reactions are produced inside a vessel, such as a torus 15, containing a gas at a pressure of about 0.1 mm. of mercury by forming a " circular discharge " within the gas by magnetic induction from a coil 19, as by way of a closed core 18. To assist in forming the circular discharge the gas is ionized by a high-frequency electrostatic field produced across the section of the torus between electrodes 22, 23. These electrodes are interrupted to avoid short circuit of the electromagnet and, with the torus, are immersed in cooling insulating oil in a lead jacket 21. The electrodes 22, 23 may be supplied with a few tens of watts at 10 to 25 kV, ¢ to 1 megacycle per second and the coil 19 with a few tens of kilowatts at 110 volts, 1000 c.p.s., producing a circular discharge of 10,000 amperes. The reaction products are removed through an outlet pipe 17, fresh gas being admitted at 16. The Specification refers to the formation of thermal neutrons when the gas is H<SP>1</SP> and to other reactions forming isobars. In alternative forms of the apparatus, the gas in a cylindrical vessel is surrounded by the coil, Fig. 1 (not shown), or in a helically shaped vessel " wound " on to a limb of the core, Fig. 3 (not shown). The reaction products may be taken to a further vessel for analysis or for reaction with other substances.

Title: Improved hop cleaning machine
IPC: A01D46/02
Filed: 1957-03-25
Abstract: 811,255. Screening apparatus. BENSEMANN, E. G. March 25, 1957, No. 9674/57. Class 117. A hop-cleaning machine, which may be mounted on wheels 77, has a hopper 39 from which the hops together with leaves, twigs and hop petals are fed by a tined roller 43 on to a curtain 33 and a screen 37 The curtain consists of a flexible chain mesh attached at its upper end to a windlass 34 and at its lower end to a batten 36 from which extend spaced flexible fingers constituting the screen. Hops fall through the fingers on to the machine floor, and are blown over a floor 15 to a receptacle 64 by the air stream of a fan 16 flowing through a duct 17. The fingers of the screen. 37 have their ends adjacent the lower end of an endless conveyer screen 18 of wire mesh or gauze provided with rows of flexible pegs 32 which carry the leaves, twigs and petals upwardly. The rollers 22, 23 and 24 support the conveyer, and one or more fans 38 force air through that part of the conveyer extending between the rollers 22 and 23 to hold the leaves and twigs in contact therewith and to force hop petals therethrough. The latter are carried with the hops to the receptacle 64. A rotary agitator 27 vibrates the conveyer and causes any hops thereon to roll down it to the screen 37.. Spiked rollers 44, 45 co-operate with the roller 43 to even out the feed and to separate hop clusters which are passed between the rollers 44 and 45. The spikes of the latter interengage, and roller 45 is driven in an opposite direction at higher speed. An adjustably mounted spiked roller 47 allows leaves to pass between it and the conveyer whereby they are fed to a trash delivery channel 59, but the roller makes contact with any hops to throw them down the conveyer. Twigs are also caught by the roller 47 and thrown upwardly to spoked rollers 50, 51 which throw them towards the upper end of the conveyer which delivers them to the channel 59. A spoked roller 52 urges any hop petals that may be blown over the roller 23 through the conveyer. Such petals and hop seeds are guided by deflectors 54 on to the floor 15. An adjustably mounted brushing roller 56 removes leaves and twigs stuck to the conveyer and feeds them to the channel 59. Grid wires 57 suspended from a bar 58 and curved over the roller prevent material being carried around thereunder. A number of transverse shafts 62 carrying spoked rollers 63 are mounted in the channel 59 and push the trash to one side of the machine and at the same time urge hop petals through a perforated floor 60 to the receptacle 64. The conveyer, fans 38 and rollers are driven by a petrol engine or an electric motor via a main drive shaft 66 and endless chains passing over sprockets.
