Filed: 1916-12-29
Abstract: 112,965. Wade, H., (Buhl, G. A.). Dec. 29, 1916. Spray evaporators.-A process for drying liquids consists in spraying them through nozzles 17 into an atmosphere consisting of the vapour of the liquid under treatment, and circulating the atmosphere through a separator 13 for the removal of the resulting solids and a heater 18 for superheating the atmosphere, the vapours generated during the operation being allowed to escape through a vent 22. The heater 18 is heated by combustion gases from a furnace 19, and the temperature is regulated by manipulating dampers in the flues 20, 21. The pressure in the system is varied by connexions 23, 24, 25 fitted to the vent 22, and leading to the outside atmosphere, a condenser and vacuum pump, and a loaded valve respectively. In apparatus for reducing sugar solutions to crystalline form, the separator 13 takes the form of screens between which the vapours and crystals pass, the crystals attaching themselves to the screens and growing outwards therefrom. Reduced pressures are used in treating milk, blood, &c. When a mixture of starch and a very dilute solution (0.4 per cent) of hydrochloric or nitric acid is treated, modified starches are obtained.

Abstract: 380,850. Recording sound optically. BRITISH ACOUSTIC FILMS, Ltd., 142, Wardour Street, London. March 19, 1931, No. 18647/32. Convention date, Sept. 26, 1930. Divided on 377,675. [Class 40 (ii).] Optical sound records of the varying width type and in which the average width varies in accordance with the amplitude of the sounds recorded are so recorded that the average width of the exposed part decreases as the amplitude of the sound increases, thereby producing a negative which on development has a minimum of transparent area and in consequence introduces a minimum of " background " noise on direct reproduction from such negative or from a second positive made therefrom. Fig. 2 shows the negative record and Fig. 3 an apparatus of the oscillograph type for recording the sound wherein the audio current from a microphone and amplifier e is divided so that a part passes by the transformer f to the wire h of the oscillograph i . and a part is fed through a thermionic valve circuit whose output is adjustable and is impressed on the oscillograph wire. The circuit; is adjusted so that when no current is passing through the wire h the line a, Fig. 2, representing average width of record is a straight line along the centre. An unmodulated current effects a displacement of the line a to or beyond the edge of the record strip, and modulation of the current effects the displacement shown. Microphonic noises and very quiet sounds are not recorded when the line a is initially displaced beyond the edge of the record. Specifications 358,993 and 363,117 are referred to.

Title: Improvements in spray heads for overhead irrigation and other such purposes
IPC: B05B3/04
Filed: 1951-08-10
Abstract: 696,337. Spray-producers. TIBB, C. E., and REYNOLDS, W. R., [Representatives of NEWTON, R. W.], Aug. 10, 1951 [Aug. 31, 1950], No. 18901/51. Class 69(iii) A spray head for overhead irrigation includes a nozzle 3, Figs. 1 and 2, secured to a plate 4 on a casing 1, and the water jet from the nozzle strikes a Pelton wheel 18 tangentially. As the wheel speed increases, weighted arms 21, Fig. 2, pivoted on a yoke member 22 on the wheel, move outwardly, and part 21a on the arms reacts on the end of a fixed stem 23 to raise the wheel partly out of contact with the jet. In the embodiment, the wheel drives, through reduction gearing in the casing, a pinion 16 which engages a fixed gear 17 on a stationary member 2. The nozzle and casing are thereby rotated about the member 2. The water is delivered at 10 and passes through an outlet 7 and hose 6 to the nozzle. In Figs. 3-5, the nozzle is mounted on a plate 31 which is pivoted about a boss 13 on the casing 1. A spindle 32, driven by the wheel 18 through reduction gearing in the casing 1, passes through a slot 33 in the plate and carries a toothed cam 36. A cam abutment 34 is fixed to the plate, and as the cam rotates its teeth engage the abutment so as to impart oscillatory angular movements to the plate. The return movements of the plate are effected through jet reaction. The casing 1 may be mounted on a bracket 8 on a tubular member 41 within a fixed body 42. The member 41 includes a water seal 44 which is slidably arranged within the body 42, and a resilient disc 46 engages a valve seating 47. Water pressure opens the valve which closes when the water supply is shut off. A mechanism for producing a step-by-step movement of the casing in accordance with the starting and stopping of the water supply, includes cam-ways 51 secured to the body 42, and an arm 53 with a guide pin 52 secured to the movable member 41. As water is supplied or shut off, the member 41 slides within.the body 42 and the guide pin engages the cam-ways to turn the spray head through a pre-determined angle. The nozzle inclination may be varied by mechanical means operable from the driven spindle so that square or polygonal areas with straight sides can be sprayed. Specification 652,470 is referred to.

Filed: 1926-07-30
Abstract: 258,841. Kahn, L. L. Sept. 23, 1925, [Convention date]. Planes, construction of; framework. - Light girders, particularly for aircraft, and aircraft wings are built up with an outer casing for resisting compression stresses and systems of inner tension members connected to the outer casing in perpendicular directions only, one system adapted to exert compressive stresses on the casing in a. direction to produce bending and the other at right angles to the first system for preventing the said bending. Fig. 1 shows a girder with two outer plates 1, 2 and inner tension members 3, 4. When used as a wing the main tension member is arranged in the direction of the span. Where the outer casing presents a concave portion it may be strengthened on the inside by ribs secured to the inner surface. Fig. 5 shows a wing profile built up from wood strips glued together with large contacting surfaces, the wasts beyond the dotted lines 7, 8 being trimmed off. At the roots of the wing the strips converge to form one or two solid members for attachment to the fuselage. The wing is formed in two halves secured together along the line a, b by glueing, fabric covering, or veneer casing. Fig. 9 shows a wing profile built up from wood veneer. Double planking may be used to increase resistance to bending and to diminish the number of inner tension members. According to the Specification as open to inspection under Sect. 91 (3) (a) the inner tension members may be omitted from the wing shown in Fig. 5. This statement does not appear in the Specification as accepted.

Title: Methods of making electrical resistive elements
IPC: H01C7/04
Filed: 1947-07-18
Abstract: 638,084. Non-metal resistances. WESTERN ELECTRIC CO., Inc. July 18, 1947, No. 19260. Convention date, April 25, 1941. [Class 37] Thermistor beads or discs or other forms of resistance element which contain the combined oxides of several metals, for example manganese, nickel, cobalt and copper, are produced by (1) the preparation of an intimate wet mixture of finely divided insoluble salts of each metal ; (2) drying the mixture ; (3) mechanically working the mixture into a loose powder ; (4) calcining the mixture in the presence of atmospheric air to convert substantially all of the insoluble salts to their oxides ; (5) mechanically working the mixture to a flaky consistency ; (6) forming the flaky mixture into the required shape and sintering it. In one embodiment the raw material consists of the sulphates of manganese, nickel and cobalt. These ingredients in the required proportions are put into a water solution which is heated and to which sufficient sodium carbonate is added to precipitate carbonates of the metals. The precipitation is washed to remove soluble impurities and the wash water used preferably contains carbon dioxide. The washed precipitate is then dried at 105‹ C. and ground to a loose powder. The latter is then converted to oxides of the metals by calcining in air for six or more hours at a temperature within the range 600-1000‹ C. with the powder so disposed, for example in a porous container, that circulation of air throughout the material is ensured. The calcined material is then worked to a flaky consistency from which, for example, thermistor disc type elements may be pressed out with integral electrodes of finely divided metallic material. If a thermistor bead resistor is required the resistance material is mixed into a paste with water and the paste deposited to form a thermistor bead on platinum connecting and supporting beads. Sintering is then carried out at a temperature higher than the chosen calcining temperature and within the range 800-1450‹ C. The starting material may consist of nitrates or chlorides instead of sulphates and the conversion may be to insoluble salts in the form of oxalates instead of carbonates. In a further modification the conversion to carbonates is omitted as carbonates themselves form the starting material. In this case the carbonates of the required metals may be mixed in a thin water suspension and the latter then circulated in a colloid mill or ground in a ball mill. The water is then filtered off and the material dried as before at 105‹ C.
