Patent GB-170382-A (GB)
Abstract: 170,382. Hill, J. de W. July 17, 1920. Valves; valve - gear. - A two-stroke-cycle engine comprises a stepped cylinder 4, 6, with coaxial overlapping pistons 13, 16; the outer piston 13 controls the exhaust ports 20 in the working cylinder, and the inner piston has a head 15 sliding in an annular pump chamber 9 and a head 16 sliding in the piston 13. The two pistons by their relative movement control the admission of the charge from the pump chaanber through an annular passage 12 between the double walls of the piston 13, to the passages 19 in the piston 16, which open into the working cylinder 8. The charge is drawn into the pump chamber 9 through the port 10 and a mechanically-actuated valve (not shown). The connecting-rod 21 is pivoted to the main piston 13 at a point 23 out of line with the cylinder axis, and is connected with the inner piston 16 by a link 22 so that the oscillation of the connecting-rod causes relative movement of the pistons 13, 16. During the first part of the upstroke, the piston 16 overtakes the piston 13, so as to connect the passages 12, 19 while the exhaust ports 20 are still open and permit of scavenging, by the new charge. When the piston 16 has closed the exhaust ports, the pump continues to force mixture into the working cylinder during a part of the upstroke. During the last part of the upstroke, the relative movement of the pistons closes the pump delivery, and the remainder of the charge in the chamber 9 is delivered to the pump chamber of another cylinder in which the piston is reaching the bottom of its stroke.

Title: Improvements in and relating to servo-motor mechanisms
IPC: F16H15/38
Filed: 1935-06-13
Abstract: 447,579. Controlling variable-speed gearing. GENERAL MOTORS CORPORATION, Detroit, Michigan, U.S.A. June 13, 1935, No. 17042. Convention date, Jan. 31. [Class 80 (ii)] A servo-motor comprises rollers 150 compressed between a friction race on a driving member 118 and a loose ring 154 and supported in a member 126, which is displaced longitudinally when the rollers are tilted about a radius of the driving member. The rollers may be tilted by a control-head 192, a " follow-up '' effect being obtained, and the apparatus may be operable irrespective of the direction of rotation of the driving member 118. In the form shown for race- and-roller variable-speed gearing, the sleeve 104 and casing 118 are continuously driven by bevel gearing 120, 108 from a driving shaft section, not shown, which is driven in opposite directions during "forward" and " reverse " driving. The rollers 150 are formed with spherical projections 152, by which they are mounted with freedom to move radially and rock universally in radial grooves 130, 148 in a cage 128, 134 secured to the longitudinally-movable sleeve 126, which acts through an arm 170 to rock a linkage which tilts the gear rollers and vary the speed ratio. Movement of the control sleeve 126 is produced by axial movement of a rod 190 carrying the head 192, which is formed with a groove 220 to engage one set of knobs 166 or the other on clips 160, Fig. 7, embracing the rollers, according to the direction of rotation of the casing 118, so that independently of this direction of rotation the clips 160 tilt the rollers 150 and cause them to spiral on the inner surface of the casing 118 and thus displace the sleeve 126 axially in the same direction and to the same extent as the rod 190 thus producing a " follow-up '' effect. The axial curvatures on the rollers 150 and race 154 are such that when the rollers are spiralling they " bind " between the races and enable a greater thrust to be exerted by the sleeve 126.

Abstract: 450,616. Valve amplifying circuits. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and MACFADYEN, K. A., c/o General Electric Co.. Ltd., Wembley, Middlesex. June 14, 1935, Nos. 17188 and 31148. [Class 40 (v)] In quiescent push-pull amplifiers (using a pair of approximately similar valves) in order to obtain maximum output with minimum distortion, the means provided for varying the grid bias applied to each valve are interconnected with means for varying the relation between the signal voltage and the input voltages to each valve. In this way, the grid bias adjustment individual to each valve and necessary to ensure that with no signal the prescribed anode current is the same for each valve is accompanied by a simultaneous input voltage adjustment so that the negative grid bias may be substantially equal to the amplitude of the greatest input voltage applied to the grid. In the arrangement shown, input voltage potentiometers 8 are connected across separate secondaries 7 and adjustable input tappings 12 are connected with the respective grids. Tappings 9 on the grid-bias potentiometer 10 are connected to the inner ends of the potentiomotors 8. The controls of the two tappings 9, 12 associated with each valve are mechanically interconnected. If the potentiometers are of the same length. the ganging provides that the distance of a tapping from the positive end of 10 is equal to the distance of the corresponding tapping 12 from the inner end of the potentiomotor 8. In a modification, the secondaries 7 are two halves of a divided transformer and a single potentiometer, centre-tapped, is connected across its ends. The centre taps of potentiometer and transformer are interconnected by the source of grid-bias so that the single potentiometer serves as two, each with an adjustable tapping connected with its grid. This form may be used to supply a number of parallel pairs of valves, each additional pair requiring an extra pair of adjustable tappings.

Title: A method and an apparatus for the continuous extraction of fatty oil from materials having large water contents and the subsequent drying of said materials
IPC: C11B1/10
Filed: 1951-07-23
Abstract: <PICT:0711432/III/1> In the extraction of fatty oil from materials of high water content, particularly fish, by means of solvents forming azeotropic mixtures with water, after the material has been freed of moisture by heating with such a solvent, it is sprayed with a solvent in countercurrent to recover the remaining oil and then dried, the materials moving continuously and in the same direction, passing through the stages of extraction of moisture, of spraying and of drying.  The apparatus preferably uses a series of three conveyers in one unit or in separate units for each of the steps of removing moisture, spraying, and drying.  The solvents specified comprise perchlorethylene and trichlorethylene. In a suitable apparatus for the process, a screw conveyer 1 is provided in a chamber having a feed hopper 2 heaters 3 and an outlet 5 leading to an elevator 6. The conveyer also acts as a disintegrator for the material.  The solvent flows in countercurrent thereto dissolving the oil from the material and at the same time forms an azeotropic mixture with the water of the material which is evaporated, at a temperature lower than the boiling point of the solvent, by the controlled heaters 3, the vapours being led off through flues 4.  The upward travelling shaft of the elevator 6 is divided into a spraying section 7 and a draining section 8, both provided with heaters 9.  The remaining oil is recovered from the material carried therethrough on the platforms of the conveyer.  The material is then emptied at 10 on to a discharge conveyer 11 and led through a bucket wheel hopper 12 to a drying apparatus consisting of conveyers 14 with heaters 13.  The dried material leaves at the outlet 16 and the vapours through the pipe system 15.  In a modified apparatus, the drying unit is built into the elevator return shaft 6, controllable heaters being provided on its walls.  The solvent may be admitted or extracted at one or more points of the apparatus.  Three parts of perchlorethylene to one of raw material by volume are required to form the azeotropic mixture; five parts of solvent to one of raw material for the whole process.
