Titanium-base alloys having the following ranges of composition are treated to improve their fracture toughness by heating to a temperature in the alpha + beta phase field and then cooling (e. g. in a furnace) at a rate not exceeding 100‹C. per hour and slower than the rate in still air until a temperature (e.g. 500‹C. ) is reached which is not greater than that at which age-hardening commences. The alloy may then be allowed to cool at an uncontrolled rate, and a stabilization treatment such as 24 hours at 500‹C. may follow

Abstract: 432,207. Hot-beverage apparatus. THORNTON, W. H., 32, Derwent Road, South Ealing, London. Jan. 23, 1934, No. 2287. [Class 129] In electrical apparatus for making tea &c. at a predetermined time, the loss of weight in the boiler on transference of the hot water to the receiver is used to operate the means for cutting off the heat supply and sounding the alarm. The boiler 9 stands on a hinged flap 7 poised by a plunger 16 actuated by a c o u n t e r -weighted lever 12. The lever 12 carries a threeway mercury switch 18. When the boiler 9 is filled with water and the main switch operated by hand, the lever 12 is lifted against its weight 15 causing the mercury switch to make contact between the terminals 19<a>, 19<b>, in the heater circuit set for operation by the time switch in the clock 5 which closes the circuit at a given moment. When the water boils, it is siphoned into the teapot 8 on the rigid platform 4<a>. The boiler 9 loses weight and the weight 15 falls, causing the mercury switch 18 to make the contacts 19<b>, 19<c> which breaks the heater circuit and completes a buzzer and lamp circuit.

Abstract: 265,947. Malard, A. Feb. 11, 1926. [Convention date]. Void [Published under Sect. 91 of the Acts]. Retractive switches have a flexible member 4 secured at one end to a. base 1 and carrying a pair of contacts 5, 6 co-operating with fixed contacts 2, 3 on the base. Between the contacts 2, 3 is located a stop 10 so that when pressure is exerted on the blade 4 between this stop and its fixed end as by a cam 9 on the shaft 7 the contacts 5, 2 first come into engagement (Fig. 2) and on further pressure the flexure of the blade separates the contacts 5, 2 and brings the contacts 3, 6 into engagement (Fig. 3). The two pairs of contacts may be connected in the circuit of a two-tone electric horn on a motor vehicle and the switch may be operated from the steering wheel of a motor vehicle as shown in Fig. 5 by the lever 14 pivoted at 15 and having its operating end in a convenient position near the periphery of the steering wheel. A number of contact strips may be operated, in the manner described by cams 9 mounted on a common shaft (Fig. 4) and arranged to actuate the contact strips simultaneously or a predetermined order. Other methods of operating the contact strips may alternatively be employed.

Abstract: 750,951. Hydraulic turbines & pumps. AKTIEBOLAGET KARLSTADS MEKANISKA WERKSTAD. Jan. 28, 1954 [Jan. 30, 1953], No. 2617/54. Classes 110(1) and 110(3) In a propeller or Kaplan turbine utilizing tidal water and in which the blades are adjustable by cranks attached to the roots of the blades and coupled by connecting rods to a hydraulic servomotor in the runner hub, the blades can be adjusted through an angle in excess of 180 degrees from and to positions in which the cranks are approximately at right angles to the turbine axis having passed in this movement through a dead-centre position. The blades 19 have roots 35 journalled in the wall of the hub and carry crank arms 37 coupled by connecting rods 39 to a yoke 41 attached to a rod 43 carrying a servo-piston 47. The rod 39 is moved past the " dead-centre" position by hydraulic means comprising cylinders 53, 55 and a piston rod 51 connected to rod 39 by a coupling 40. The blade is adjustable while running through 220 degrees; this allows for complete reversal of the blade and an adjustment of 40 degrees in dependence upon the load. Fixed or adjustable guide blades may be provided on both sides of the rotor. The rotor first acts as a turbine with downward flow until the level in the supply basin approaches sea level. The blades are then reversed and the rotor is operated in the same direction as a pump until the basin is nearly empty. The blades are then turned to close the conduit and the unit is stopped. When the sea level has risen the blades are turned to the previous position and the rotor is operated in the reverse direction as a turbine. Finally the blades are again reversed and the rotor is operated as a pump to fill the basin.

Abstract: 538,729. Fluid-pressure servomotor control systems. BRISTOL AEROPLANE CO., Ltd., MARPLES, E. I. B., and GORRELL, H. N. Feb. 13, 1940, No. 2781. [Class 135] [Also in Group XXVII] In an aircraft engine having two blowers with the carburetter between them, the first-stage blower being brought into operation above a certain altitude, the throttle valves in the blower inlets are connected to means whereby one of these is held in the fully-open position while the other is left free to be operated by the usual hand and automatic control. Fig. 1 shows the carburetter 15 with a blower 16 on its intake controlled by a throttle 17, the mixture from the carburetter being led to a second blower 13 past a throttle 14. The latter throttle is connected by a toggle 22, 23 to the usual hand control 21 of the datum of the automatic boost control comprising a capsule 18 exposed to blower pressure and operating the valve 28 of a servomotor 34 connected to the joint of the toggle. The capsule 18 acts through a lever 25, which is also connected to the valve 29 of another servomotor 38 controlling the throttle 17. A shaft 44 carrying cams 45, 46 and operated by a hand lever 49 is arranged so that one or other of the cams holds its valve in its lowermost position. The lever 49 is also connected to the driving-means of the blower 16, the arrangement being such that, when the blower 16 is inoperative, the cam 46 is engaged with the valve 29 as shown, whereupon the piston 38 is moved to its uppermost position, and the throttle 17 is held wide open. At the same time, the cam 45 is clear of the valve 28, so that the throttle 14 is controlled by the capsule 18. When the blower 16 is switched in, the cam 45 holds the valve 28 down and the throttle 14 fully open, while the throttle 17 is subjected to the control of the capsule through the other end of the lever 25. In a modification, the two throttles are connected to the opposite ends of a lever, which is connected at an intermediate point to the toggle 22, the two cams also acting on the two ends of the lever respectively. In another form the capsule is connected to a single valve controlling both servomotors, and the cams are replaced by a valve controlling the supply of pressure fluid to the servomotors. In other modifications, there are two capsules, one for each throttle, and the required operation is effected by (1) a valve connecting one capsule to the delivery and the other to the inlet of the main blower, or (2) by a valve controlling the supply of pressure fluid to the two servomotors, or (3) by a pair of detents acting on the two capsules so as to hold one or other of them downwards in the position corresponding to full opening of its throttle.

A method of processing tobacco for use in the production of cigarettes comprises bringing the moisture content of the tobacco to a value comparable with that of the finished cigarettes, heating the tobacco, cutting the hot tobacco, cooling the cut tobacco and using the cooled tobacco to produce cigarettes. Prepared tobacco 1 is moistened so that it contains 12-14% of moisture at 2 and is metered at 3 to heating means 5, which increases its pliability. The hot tobacco is then cut at 6 and cooled at 7. Stem portions are separated and flattened at 9. The flattened stems may be fed back for mixing with the prepared tobacco to be moistened, or may be fed to a cutter 10 and then mixed with the cut lamina from 7 for feeding to a cigarette making device 11. Instead of heating means 5, a heating and moistening device 13 may be used in which case the tobacco is cooled and dried as indicated at 7A.

Recovering fats and oils from waste waters.- Neutral grease is obtained from wool-washing waters by churning to form a froth or scum, washing the scum, settling, and heating under pressure. For example, washing water from a pipe A flows through channels C<1> - - C<4> in which it is churned by oppositely rotating pairs of paddles R<1>, R<2>. The scum overflows to a zig-zag channel D in which it is sprayed with water from atomizers P<1> - - P<3>, the heavy impurities settling into pockets E.
