Title: Methods for separating the components of alloys
IPC: C22B7/00
Filed: 1925-10-02
Abstract: Alloys such as bronzes are treated for separating their ingredients by heating with a mixture of sulphur an alkali sulphide, polysulphide or thiosulphate and treating the residue with water or a solution of alkali sulphide.  Lead and copper sulphides remain insoluble, and are roasted to obtain oxides and treated with sulphuric acid to obtain sulphates.  The thio-salt solution is treated with sulphurous acid to precipitate tin and antimony sulphides which are heated to sublime the free sulphur and roasted to obtain oxides and yield the sulphur dioxide necessary for the precipitation.  The oxides may be reduced and the metals separated.  The alkali salts left after the precipitation of the tin and antimony sulphides, consisting of sulphates, thiosulphates, and sulphides, are reduced to sulphides by heating with carbon.

Title: Combined disk and shoe brake
IPC: F16D55/14
Filed: 1954-08-24
Abstract: 767,706. Combined disc and drum brake. BENDIX AVIATION CORPORATION. Aug. 24, 1954 [Nov. 16, 1953], No. 24612/54. Class 103 (1). A brake has two friction shoes 10 and 12 each of which is adapted, for a particular direction of drum rotation, to pivot about its pivot mounting 14 or 16 into engagement with the drum 24 as a result of the application of fluid pressure between the pistons 46 in cylinders 44 carried by the units, by which friction pads 48 are engaged with radial faces on the drum casing. Thus, when rotation of the drum is anti-clockwise, since the shoe lining 40 tends to be displaced away from the drum into engagement with an abutment 70, braking is produced by disc friction for unit 10 and disc and shoe friction for unit 12. Similarly with clockwise rotation braking is by disc action for unit 12, and disc and shoe action for unit 10, but the rotational movement produced on the shoe of unit 12 is transmitted through a strut member 50 to the shoe of unit 10 to increase the applying force thereon. The brake shoes may be applied mechanically through a cable 86 and lever 54 with pins 56 and 82 acting as fulcrums. In another embodiment described, the strut member between the shoes comprises automatic adjustment mechanism. Specifications 758,882 and 767,707 are referred to.

Title: Improvements in and relating to gyroscopic apparatus for determining the inclination of a plane
IPC: G01C19/44
Filed: 1936-09-11
Abstract: 464,193. Gyroscopic apparatus. SIEMENS APPARATE UND MASCHINEN GES. Sept. 11, 1936, No. 24839. Convention date, Oct. 18, 1935. [Class 97 (iii)] The deviations of a gyroscope 1 for maintaining a plane stabilized relatively to the horizontal are corrected by means, e.g. the pendulums 16, 17, responsive to variations in the inclination relative to the apparent vertical of a body 13 the inclination of which is made dependent upon the position of the plane maintained by the gyroscope. The gyro 1 with vertical spin axis 2 pivots on a fore-andaft axis 4 in a gimbal ring 5 pivoting in turn on a transverse axis 6 in the supporting aircraft. Rotations of the gyro about the fore- and-aft axis 4 are communicated by a crank 9 to a horizon disc 7. Rotations about the transverse axis 6 are indicated by a model 8 secured by an arm 10 to the ring 5. The indicators 7, 8, co-operate with pointers 11, 12 and scales 14, 15 on the body 13 which may be fixed to theaircraft. The pendulums 16, 17 pivot on the body 13 about axes normally parallel to the axes 6, 4, and co-operate with contacts 25, 26, and 27, 28 to control the. electric circuits of coils 20, 21, which coact with magnets 18, 19 on the axes 4, 6, respectively to apply correcting torques to the gyro 1. In use the aircraft is flown or the body 13 separately adjusted so that in straight flight the horizon line on the disc 7 and the model 8 register with the pointers 11, 12, and in curved flight so that the horizon line on the disc 7 makes an angle with the line of the pointers 11, 12, equal to the angle between the true and apparent vertical as determined from the speed and rate of turn. Thus the body 13 will follow the apparent vertical and the contacts 25, 26, 27, 28, therefore remain open unless' the gyro has deviated from the true vertical in which. case the appropriate correcting torques will be introduced. Instruments 23, 24 in the circuits of the pendulums 16, 17 indicate when the body 13 is not following the apparent vertical correctly. The gyro may operate a switch controlling automatic steering apparatus and during curved flight the angle between the true and apparent vertical may be automatically introduced at the switch from a combination of the indications of a speedometer and turn indicator. The pendulums 16, 17 instead of opening and closing contacts may be provided with tappings which are shifted along potentiometers. Hydraulic or pneumatic means may be employed for applying the correcting torques.

Title: Improvements in or relating to central heating systems
Inventor: WOLFENDEN HENRY CHARLES LEONAR
IPC: F24H9/20
Filed: 1961-07-11
Abstract: 1,022,631. Central heating systems. RADIATION Ltd. Oct. 11, 1962 [July 11, 1961], No. 25093/61. Heading F4U. In a central heating system in which hot water is pumped from a boiler burning fluid fuel, a first thermally operated switch S1 controls the fuel supply to the burner and the motor driven water pump over a predetermined temperature range, and a second thermally operated switch S2 controls the water pump only over a temperature range in which the lowest temperature exceeds the highest temperature of the range set on S1. For example, S1 may operate to open at 170 F. and close at 165 F.; S2 may operate to open at 190 F. and close at 185 F. Thus S1 terminates heat input to the boiler and de-energizes the burner 6 at 170 F. Due to the thermal capacity of the boiler, the water temperature will rise to 190 F. at which temperature S2 opens and operates pump 6. The pump will continue to operate until the water cools to 185 F. when S2 will close. At 165 F. S1 is closed and energizes the coil 7 of an electromagnetic valve in the fuel supply line, and the pump 6 to recommence heating the boiler and circulating the water. Switches S1, S2 are both operated by a thermally responsive element exposed to the heat of the water leaving the boiler. The system may include other elements such as a thermal device responsive to ambient temperature changes operating a switch S3 in series with S1. There may also be a clock-operated switch in series connection with S1.
