Abstract: 406,034. Fluid-pressure horns. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.- (Assignees of Compagnie des Freins Westing- house ; Seine, France.) Aug. 19, 1932, No. 23309. Convention date, Jan. 16. [Class 13.] In a sound-producing device of the kind comprising a diaphragm which vibrates under the action of pressure or vacuum in a chamber communicating with the atmosphere through a valve actuated by the diaphragm and in which the latter is provided with a weight, the weight member constitutes the valve itself. In Fig. 1, the diaphragm 3 is provided with a weight comprising a member 10 with stud 11 and nut 14 and a flanged sleeve 12, a washer 13 of leather &c. being clamped between them, which washer bears upon the valve seat 9. On the supply of pressure fluid through aperture 16 the diaphragm draws the valve away from its seat and consequently the pressure is released causing the valve to re-seat itself and so setting up vibrations in the column of air in the horn conduit. In the form shown in Fig. 2 for actuation by vacuum the seating is arranged to face the other way and the same action results.

Abstract: 910,651. Rotary wing aircraft. SHAPIRO, J. S., MEADS, B. A. G., and PRESTON, R. L. Oct. 22, 1959 [July 22, 1958], No. 23458/58. Class 4. A coaxial contra-rotating rotary wing aircraft rotor system having component rotors each of which can tilt as a whole about an axis perpendicular to the common rotational axis, comprises an assembly disposed between the rotors, and concentric with and universally tiltable about the rotational axis, the assembly being composed of two races rotatable independently of each other about the rotational axis, each race being constrained to rotate and flap with one of the rotor hubs. In Fig. 1, a drive shaft 1 supports a hub 5 through a spindle 7, and the hub has pivots 9, 11, on which arms 19, 21 rigid with a member 13 and the blades 15, 17 are rotatably mounted. Similarly, shaft 3 supports a hub 5x and blades 15<SP>x</SP>, 17<SP>x</SP>. The two races 23, 25, are supported concentrically with shaft 1 by means not shown. Race 23 is connected to hub 5 by two pairs of rods 27, 29, universally pivoted to the race at joints 31, 33, and to bars 39, 41 rigid with the hub at joints 35, 37, respectively. Race 25 is similarly connected to hub 5<SP>x</SP>. By this means, when the upper and lower blades cross, i.e., are contained in the same plane through the axis of shafts 1 and 3, they are constrained to have the same flapping angle, and fouling of the blades is prevented. Any drag hinges or pitch change bearings must be provided outboard of arms 19, 21, 19<SP>x</SP>, 21<SP>x</SP>. A similar embodiment is described for three bladed rotors, in each of which the blades cannot flap with respect to the hub, the latter being universally mounted on its drive shaft. In this case each pair of rods 27, 29, 27<SP>x</SP>, 29<SP>x</SP>, is replaced by a single link extending from the blade root to the appropriate race. The Provisional Specification describes a similar embodiment for two bladed rotors, each of which comprises two blades fixed to a hub which is tiltable on its drive shaft about an axis transverse to the spanwise axis of the blades.

Title: Improvements in the manufacture of soap
IPC: C11D13/04
Filed: 1948-09-10
Abstract: <PICT:0662648/III/1> <PICT:0662648/III/2> Kettle soap remaining after the spent lye and glycerine have been removed from the mass resulting from the saponification of fats is finished by conditioning it with sufficient water to convert it to a homogeneous condition having a fatty acid content of 40-66 per cent, agitating, withdrawing a continuous stream, mixing a stream of electrolyte therewith sufficient to cause a neat soap phase to be formed having a fatty acid content of 38-62 per cent, maintaining at a temperature of not less than 180 DEG C. and centrifuging the mixed stream to separate neat soap therefrom. The conditioning step is preferably carried out near the boiling temperature, and if necessary sufficient sodium chloride or caustic soda or both are added to close the grain to such an extent that the mass is substantially homogeneous and may be so maintained by the mild agitation provided by pumping through a pipe system.  Preferably the fatty acid content of the conditioned mass is between 50 and 59 per cent, and that of the mixed soap and electrolyte stream from 45 to 55 per cent.  Referring to Fig. 1, a batch of kettle soap is introduced into a tank 10 and boiled with water and, if necessary, small amounts of electrolyte by live steam entering from the pipe 11.  The conditioned soap is circulated by a pump 16 through a strainer 14 and back to the tank, while a portion is continually bled off through a pipe 20 and pump 21 to be mixed with electrolyte pumped in by a pump 24 from a constant level tank 30.  The mixture passes to a circuit 37 containing a pump 36, a heat exchanger 39, a drain 40, and a throttle valve 46 leading to one or more centrifuges 44 from which neat soap is discharged on the light side 47 and nigre or lye on the heavy side 49.  If desired the electrolyte may be added in the dry state by depositing it on a vibrating screen 71 from which it is guided by a sloping plate 72 to a funnel 56, as shown in Fig. 3.
