Title: A new or improved apparatus for removing slack and dirt from coal cutting machines
IPC: E21C35/20
Filed: 1919-11-14
Abstract: 158,128. Russell, A. Nov. 14, 1919. Endless-chain machines.-For removing dirt and slack from the vicinity of coal-cutting machines, travelling scrapers are provided mounted on chains which may be adapted to be actuated by the movement of the cutters in chain machines. The chains 2 carrying the scrapers 1 pass over sprocketwheels 5 mounted on shafts 3 and may be driven from an independent source of power by a pulley 6 mounted on one of the shafts, or, in the modification shown, may be actuated by carriers 11 of the type described in Specification 158,718, of a chain machine. Each carrier in turn bears upon a projection 12 of a slidable member 13 working in slots 15 in a plate 16. The member 13, in moving forward, actuates a rod 20 against a spring 23, thus causing rotation of the shaft 3 through links 24, 25 and ratchet mechanism 26, 27. The slots 15 in which the sliding member 13 works, are of the shape shown dotted in Fig. 3 so as to give a lateral movement to the member 13 to clear the carriers 11 at the end of the stroke, after which it is returned to its original position by the spring 23.

Filed: 1936-10-21
Abstract: 483,573. Testing dough. BRABENDER GES. Oct. 21, 1936, No. 28644. Convention date, Feb. 10. [Class 58] The structural properties of dough are tested by forming the dough into a roll and measuring and recording the resistance which the roll opposes to extension by a hook driven by a motor. A sample of dough is rolled by a motor-driven roller 14 in a casing 13 wherein it is pressed during its passage from an inlet 15 to an outlet 16. On leaving the casing the dough slides past a measuring bar 20 and presses out a number of slidable teeth 17 corresponding to the width of the roll. The roll is then placed in a holder 4 and an electric motor 2 suspended freely in bearings 3 drives a hook 1 through the dough, the resistance offered by the dough causing the motor casing to move and operate through a rod 6, a balance 8 associated with a recording device 9. Oscillations are damped by an oil dashpot 7. In a modification the holder for the roll of dough is carried by a lever system connected to the balance, and the motor casing is fixed. Two rubber bands moving at different speeds may be used to roll out the dough.

Title: Improvements in or relating to a process for separating a constituent from a stream of material
IPC: B04C5/00
Filed: 1959-08-21
Abstract: 933,224. Centrifugal separators. SIEMENSSCHUCKERTWERKE A.G. Aug. 21, 1959 [Aug. 22, 1958], No. 28690/59. Class 23. A process for separating a constituent from media flowing axially in a cylindrical vessel 20 and comprising constituents of different specific gravity comprises creating a potential flow 23 by stirring means which rotate about the axis of the tube and/or by means of obliquely tangential injection of a secondary medium into the tube by way of a duct or ducts that do not project into the tube, the potential flow having an axial velocity component directed oppositely to the direction of flow of said media and an angular velocity component and setting up, by the action of the potential flow on a rough ground, a rotary flow 24 having an angular velocity component in the same direction as that of the potential flow and an axial velocity component in the same direction as the flow of media, the process being such that the constituent of greater or greatest specific gravity is collected in a zone in the vessel and discharged therefrom by a part 29 of the potential flow divided off at a point before the potential flow reaches the rough ground. Potential flow is defined as a flow in which the particles do not rotate, or rotate only to a slight extent, about their own axes and rotary flow is defined as a flow in which the particles do rotate about their axes. A rough ground occurs when the axial velocity of the potential flow is reduced to zero. As shown, for a smoke gas dust separator 20, the potential flow is created by secondary air injected through oblique tangential nozzles 22 and the rough ground occurs just above the inlet pipe 21 for the smoke gas. Dust separated out in the zone indicated by coils 27, 28 is discharged at 29. A two-stage dust separator comprising a vertical tube divided into sections by spaced horizontal sheets of wire gauze is also shown and described. The media may be gaseous, liquid or solid substances or mixtures thereof. Specifications 752,353 and 933,225 are referred to.

Title: Improvements in vehicle couplings
IPC: E21B10/34
Filed: 1922-10-23
Abstract: 206,681. Santz, A. Oct. 23, 1922. Couplings for road vehicles and trains.-In a hook and link coupling the frame for the reception of the coupling hook is provided with a recessed portion or aperture intermediate the hook and front of the vehicle which is adapted for the reception of the coupling link so that in the inserted position the upper portion of the link covers the mouth of the coupling hook whilst the lower portion bears against a stop on the frame. The coupling hook 2, Fig. 1, has an extension 4 which is bent at 5 to form a closed eye for the coupling link 6. An aperture 7 in the frame work 1 is adapted to receive the link 6 and a stop 8 forms a ledge on which the bottom of the link rests when the coupling is locked. In Fig. 3, the extension 4 forms a " T " head, the cross-piece 9 of which forms a stop for the link 6 when the coupling is in the locked position.
Patent GB-749790-A (GB)
Title: Improvements in or relating to automatic frequency control systems
IPC: H03L7/04
Filed: 1953-10-20
Abstract: 749,790. Automatic frequency control. COLE, Ltd., E. K., COX, V. J., and REEVES, R. J. D. Oct. 20, 1954 [Oct. 20, 1953], No. 28888/53. Class 38 (4). In an automatic frequency control for a klystron oscillator the reflector electrode potential is controlled at a value which causes the klystron to oscillate at a frequency differing from a reference frequency by a fixed value, and the cavity adjustment is controlled to maintain the klystron on an appropriate mode, the two controls being interdependent jointly to cause the oscillator to produce the required frequency at the centre of the mode, irrespective of the output amplitude. The output of the klystron 2 is applied to a crystal mixer with pulses of the reference frequency, from source 1. When an intermediate frequency of the right order is produced it is amplified at 4 and fed to the frequency discriminator 5. The " sum " frequency discriminator output' applied ' to the amplifier 18 is arranged to be zero when the klystron is off tune so that a " lock-on " relay 7 is de-energized, its contacts 9, 16 being in the positions shown. The " difference " frequency discriminator output applied through contact 20 to the Miller integrator 6, 21 and klystron reflector is zero when the klystron is exactly on tune. In order periodically to sweep the frequency over a range including the desired mode, a single sinusoidal wave is produced at intervals by the generator 10 and applied to the klystron reflector. The D.C. output of the crystal mixer is applied to a " time discriminator " 8, controlled by the sinusoidal wave, during this sweep period, to produce a voltage, of magnitude and polarity depending upon the extent to which the klystron is off the centre of the mode, which voltage is applied over contact 9 to correct the potential of the klystron reflector. During this time a search bias applied to the motor-control amplifier 11 causes a motor 13 slowly to move the klystron cavity-tuning plunger, through reduction gear 14 and cam 15, so that in course of time the klystron frequency is such as to produce an I.F. output from amplifier 4. The relay 7 is thus energized by the- " sum " output of discriminator 5 and the output of the time discriminator 8 is transferred, by contact 9, to provide an over-riding control for the motor 13, while the " difference " frequency discriminator output controls the klystron reflector potential. In order that the correct sense of the discriminator output may be used for frequency correction, a phasing relay 19 reverses the position of the contact 20 once for every two operations of contact 16 of the lock-on relay 7, being controlled by contact 16 through a binary scaler 17. The motor 13 has a two-phase winding, one of the phases being reversible under the control of a polarized relay 12, operated by the amplifier 11, and having a neutral position which brings the motor to rest. Suitable circuits for the components of the system are described, Figs. 1a, 1b, 1c (not shown).
