Title: Improvements in and relating to rotary wing aircraft
IPC: B64C1/00
Filed: 1945-07-02
Abstract: 601,999. Controlling aircraft. SPERRY GYROSCOPE CO., Inc. July 2, 1945, No. 16843. Convention date, June 30, 1944. [Class 4] A controller for suppressing irregularity of flight movements in aircraft having rotary wings comprises means (such as an accelerometer producing an electric control signal) responsive to sudden movements of the aircraft so as to produce a control impulse for changing the pitch angle of the wings and thus altering the lifting or propelling power to counteract the forces causing deviation of the aircraft from the normal path. The armature 53, Fig. 2, of an accelerometer B on the aircraft moves up or down when an irregular vertical movement occurs and causes a current to be produced by the exciting coil 64 of an E- transformer (carried on the outside of the accelerometer and connected to an A.C. source) in the secondary coils 65, 65<SP>1</SP>, oppositely connected to produce zero current only during steady movement of the craft. The current produced by the transformer during irregular movement is led into the circuit shown in Fig. 1 to start up in the appropriate direction a servo-motor 44 and drive a pinion 25 carrying a nut 27 whose rotation on the threaded lower part of vertical shaft 31 will raise or lower the shaft to change the pitch of the rotary wings of which one, 11, is shown together with linkage connected to the top of the shaft 31. The carburettor of the motor 19 driving the hollow shaft 12 carrying the wings is controlled by, a bell-crank lever 39 on the shaft 31 to adjust the power supplied as the pitch is altered. The control current picked off from the accelerometer is led through the primary 71 of a transformer with secondary 72 connected to a double-triode amplifier tube 73 to which the servo-motor 44 is connected through a reversing relay D selectively operated by means of the amplifier tube 73, which is supplied with alternating current from source 81<SP>1</SP>. The grids of tube 73 are connected to the two ends of coil 72, to the middle of which the cathodes are tapped so that for one direction of movement of the armature 53 one of the triode paths is open to one half of the cycles of A.C. source 81<SP>1</SP> and the other is continuously non-conducting ; the direct current thus obtained energizes one or other of the coils 82, 83 of the relay D to supply current from D.C. source 81 to motor 44 in the appropriate direction. A repeat-back transformer with coils 104, 105 connected in the control circuit has its coils adjusted by gearing 102, 103, when the servomotor 44 is in action, and then serves to reduce the control current to zero and to supply a current which leads to a reversal of the servomotor 44 to restore the original pitch of the rotary wings. Irregular motion in the horizontal direction is controlled by means of two accelerometers F and K, at right angles to each other, and acting through a wobble-plate 113 to produce a cyclic change in the pitch of the wings 11 and thus provide horizontal components of wing thrust to counteract the irregular horizontal movements.

Abstract: 169,681. Naamlooze Vennootschap Handelmaatschappij Capaso, (Assignees of L÷bbe, TV.). Sept. 30, 1920, [Convention date]. Rotary and oscillating conical valves.-In a revolving-cylinder engine of the type in which radial cylinders contain pistons running on cam tracks, and the axle b, Fig. 3, of the cylinder groups is supported at both ends in bearings in the casing d a conical distributing valve k is employed, which is balanced axially by the opposed actions of the fluid pressure and the interaction of a stationary cam and a cam on the valve. A ring w<1> secured to the valve k has a cam edge engaging a similar cam edge on a non-rotating ring v<1>. If the axial pressure of the fluid causes the valve to grip in its seating, it commences to turn with the cylinders, whereupon the reaction between the cam rings w<1>, v<1> releases it. If the speed becomes excessive, a centrifugal governor m<1> presses a sleeve o<1> axially against the action of a spring p'. The thrust of the sleeve is transmitted through a ball bearing u<1> to the ring v<1>, and the reaction between the rings v<1> and w<1> rotates the valve k, giving a later admission. In a modification, which is especially adapted for use with compressed air, no governor is employed and the angular position of the ring v<1> can be adjusted by a lever to reverse the engine. The valve k may be packed by double, interrupted, eccentric screw threads k<1>, Fig. 4.

Title: Improvements in coking apparatus
IPC: C10B1/04
Filed: 1932-06-16
Abstract: 392,751. Apparatus for low-temperature carbonization. PUENING, F., Koppers Building, Pittsburg, U.S.A. June 16, 1932, No. 17097. Convention date, June 24, 1931. Addition to 362,522. [Classes 51 (i), 51 (ii), and 55 (i).] In apparatus for the production of lowtemperature coke, and of the kind described in the parent Specification in which the coke chambers are enlarged through movement of their heating walls to discharge the coke, the side walls of the housing are located adjacent the movable heating walls, whereby the side walls act as lateral boundaries to the coking chambers. A housing 1 contains a number of movable heating walls 4 hung from their tops, and supplied with hot gases from a furnace 3. The heating walls 4 are spaced to provide coking chambers 5, which are fed from a hopper 12, a bottom door 14 being removed for discharging the coke. The side walls 18, 19 are hollow to allow of circulation of the heating gases by a fan 17 through parts 20 leading to the interior of the heating walls 4 which are suspended from rods 8 by universal joints 25. The direction of the path of the hot gases is controlled by dampers, one of which 32 is shown, and is periodically reversed, surplus gases being withdrawn through an outlet 72, and the remainder being re-circulated with fresh gases from the furnace 3. These heating gases pass in one direction through an opening 70 into the housing 1, through a port 34 into passages 29 leading to the hollow wall 19, from which inlet ports 20 lead through the heating walls 4 to outlet ports 20, hollow wall 18 and opening 36, through which they are drawn by the fan 17 for re-circulation. By operating the dampers, the direction of the gases through the heating walls 4 may be reversed. The distillates are removed through an outlet 39 from a free space 80 over the charges. The hanging walls 4 are flared at the bottom 81, Fig. 7, to retain the coke until the walls are separated by apparatus carried on a coke wagon 54, Fig. 12, and comprising a number of vertical rods 55 each of which engages a recess 56 in the bottom of each of the hanging walls 4. The rods are mounted on a girder 57, which is raised by a motor 58 through gearing 59, and, after a displacement body 67 is lowered, are operated by cams 66 rotated by a horizontal rack 65 so as to separate each of the walls 4 in turn, and allow the coke to fall into the wagon. After discharge, the walls are returned to their normal position, the displacement body 67 is raised, and the bottom closure is replaced. The heating walls are spaced apart by lugs 75 at the top, and projections 76 on the bottom door 14. In Fig. 14, the heating walls 4 are provided with extensions or projections 4<11> which bound the sides of the coking chambers. United States Specification 1,799,702 is referred to.

Filed: 1973-04-11
Abstract: 1427065 Protective arrangements; D.C.- D.C. converting SONY CORP 11 April 1973 [14 April 1972] 17314/73 Headings H2K and H1F A power supply circuit for an electronic load 13 has a fuse 2 or a circuit-breaker connected in series with a voltage regulating device, e.g. a transistor 3, between input and output terminals 1, 7, a control transistor 10 for the regulating device and a transistor 14 controlling a protective circuit being connected to a common voltage detecting device, e.g. potentiometer 11. As shown the transistor 10 responds to the voltage at the tapping 11a on the potentiometer to control the transistor 3 through a pulse width modulating circuit 12 or directly, Fig. 3 (not shown). In the event of over voltage due to failure of a component, the transistor 14 conducts to cause a silicon controlled rectifier 16 to conduct sufficient current to blow the fuse 2. In a further arrangement, Fig. 2 (not shown), in which the load is the horizontal output circuit of a TV receiver, the transistor 14 conducts to render a gate controlled switch (25) in that output circuit continuously conducting to increase the load current to blow the fuse 2. In this arrangement the transistor 3 is controlled by a pulse-width modulating circuit 12 supplied from a fly-back transformer (30) in the load circuit so that when the supply is first turned on, no voltage is available for turning on transistor 3. A capacitor (37) is therefore connected between the load side of fuse 2 and the circuit 12 to produce a starting pulse.

Title: Manufacture of organic calcium sulfonate
Filed: 1956-06-06
Abstract: Oil solutions of basic calcium sulphonates are prepared by a single-stage process comprising adding to an oil solution of a sodium sulphonate at least 0.5 and less than 1 mol. of calcium hydroxide and from 1.0 to 1.2 mols. of an aqueous solution of calcium chloride per mol. of sodium sulphonate and then reacting the mixture.  In an example 1.2 mols. of 40 wt. per cent calcium chloride and 0.5 mols. of dry calcium hydroxide are added to a 50 wt. per cent oil solution of sodium petroleum sulphonate and the mixture diluted with oil to 30 wt. per cent sulphonate concentration.  The temperature is raised from 30 DEG  to 150 DEG  C. in one hour to effect simultaneous reaction and dehydration.  The product is filtered at 150 DEG  C. with 0.6 per cent filter aid and an oil solution of basic calcium petroleum sulphonate is obtained as the filtrate.  This is contrasted with a two-stage process of the prior art wherein the sodium sulphonate solution is first reacted with 2.5 mols. of 22 wt. per cent calcium chloride solution, the mixture is settled and the aqueous layer discarded, and the product is then further reacted with lime to obtain the basic sulphonate.

June 20, 1933, No. 17569. Convention date, Oct. 4, 1932. [Class 31 (i).] A blank is punched out from a sheet of interleaving material which is fed between a die and a web from which blanks are punched, at certain working strokes only of the punch, these working strokes being followed by at least one other in which no blank is punched from the interleaving sheet. Thus, by using a sheet of paper 2 of distinctive colour, texture or thickness from the web 1 from which blanks are punched by a co-operating punch 5 and die 4, the punched blanks may be readily divided into packets or batches divided by blanks of paper. This may be achieved by driving the roll 16, on which the paper from a supply 3 is wound, by a mutilated gear 13 which is actuated through a chain of gearing 11, 10, 8 from the shaft 7 which operates the punch 5, when the punch is withdrawn from the web 1.
