Title: Improvements in or relating to magnetic compass devices
IPC: G01C17/00
Filed: 1935-11-22
Abstract: 467,735. Magnetic compasses. SPERRY PRODUCTS, Inc. Nov. 22, 1935, Nos. 32430 and 32431. Convention dates, Dec. 7, 1934 and Oct. 25, 1935. [Class 97 (ii)] [Also in Group XXV] A compass for use on aircraft comprises a magnetic sensitive element supported for universal movement and a pendulous element for applying a torque to the magnetic element the pendulous element being so controlled that the law of variation of the torque is changed, when acceleration forces acting on the said element exceed a predetermined magnitude. The torque increases until the forces reach the predetermined magnitude and then remains substantially constant. In Fig. 1 the sensitive element comprises a casing 20 including two floats 12, 13 which contain the magnets 10, 101 and are mounted on a rod 11 rotatable on bearings 17, 18, complete rotation being prevented by stops 71. An inner portion 22 of the case 20 contains a bowl 60 in the shape of a surface of revolution of a circle centre 0<11> about a line 00<1>, Fig. 5, a ball B resting in the bowl comprising the pendulous element. The casing 22 also carries a pivot 58 to mount the element universally on a pivot post P inside the spherical container C which is filled with liquid and fitted with an expansion chamber 29 and a lubber line 142. The position of the pivot 58 is adjusted to be in coincidence with the centre of gravity and centre of buoyancy of the sensitive element and the ball B is so chosen that the whole element is slightly pendulous. The pivot comprises a substantially spherical end 31 to a staff 33, Fig. 4, which touches the inner surface of the spherical cup 30, carried by the post P, tangentially at the point 50. The point is prevented from moving apart by the framework 58 which is loosely mounted over the joint to permit free rotational movement, the knob 31 being held against the cup 30 by the buoyancy of the sensitive element. The floats rotate until the magnets lie at the angle of dip and the element rotates as a whole until the magnets point to the magnetic north when a bearing may be taken by the lubber line 142 on a scale on the outside of the sensitive element. For small values of the acceleration force the ball remains in the notch N, Fig. 5, and the whole swings as a pendulum, but when the force becomes greater the ball leaves the notch and runs on the smooth surface of the cup thus changing the torque on the sensitive element. In the form shown in Fig. 13 the pivot comprises a conical jewel J pressed against the pivot post P by the buoyancy of floats 120 which contain the magnets 110, 111 carried on rotatable rods 114. The jewel carries three members 131, 1311, 13111 which support the pendulous member 130 and are attached to the jewel at points such as 140, 140<1>. For small forces the pendulum swings as a whole, all three members being taut, but for larger forces one or other of the members becomes slack causing the torque about the pivot to be changed.

Abstract: 212,293. Line, A. J. Dec. 2, 1922. Curving; coiling. - A machine for bending and coiling tubes, particularly for bending round or rectangular tubes of gold and silver for making bangles and bracelets, consists of a pair of rolls of different diameters through which the tube is passed and an adjustable pivotally mounted member disposed between the rolls against which the tube is forced to form the required radius. Grooved rolls 4, 5 of different diameter are geared together by toothed wheels of equal diameter. The rolls are pressed apart by a spring 21 and the upper roll adjusted by a screw 20. The tube is passed through the rolls without any pressure being imparted thereto, and the end is slightly bent by the curved grooved end 10 of a block 9 adjustable by a nut and screw 19 on an arm 12 which is pivoted at 13 and adjusted by a pair of screws 15, 16 according to the radius required. The inner radius of the tube thus comes into contact with the roll 4 and the outer radius into contact with the lower roll, whereupon the rolls are rotated to bend the tube to the desired radius. The member 9 may be provided with a member slidable in and projecting from the lower end thereof to form an additional support for the tube. The tube may be filled with sand prior to bending. When forming a coil, the forward end of the tube on forming the first turn is deflected so as to form the next turn.

Patent GB-506654-A (GB)
Title: Improvements in feeding apparatus for sound films and strip sound records
IPC: G03B31/02
Filed: 1937-12-01
Abstract: 506,654. Sound-film speed controlling devices. KOLB, O. K. (Beer, P. F.) Dec. 1, 1937, No. 33214. [Class 40 (ii)] [Also in Group XXXV] Relates to devices for controlling the speed of a film or like sound record, which is fed over a flywheel roller at or near the soundreproduction point, and consists in driving the roller by a synchronous motor supplied with current from an A.C. generator, the frequency of which is controlled by means dependent upon variations in the speed of the film. In the arrangement shown in Fig. 1, the film is driven by sprocket wheels geared to a driving motor (not shown), over a flywheel roller V, which is directly coupled to a synchronous motor M. The motor is driven by current from an oscillation generator G, the frequency of which is determined by the constants of an oscillation circuit K, and is normally such that the motor M drives the flywheel at a speed at which the peripheral velocity of the roller V corresponds exactly to the mean velocity of the film. Rollers R, R<2>, coupled by a spring, bear upon bights in the film, the roller R being connected through a spring F to a slider arm A which controls the resistance r in the circuit K. A dashpot or the like B damps the motion of the roller R. If the speed of the driving motor is suddenly reduced, the lower film bight is shortened, and the spring F is compressed. No action on the arm A takes place if the speed variation is momentary, but if it is of long duration (due, for example, to shrinkage of the film), the arm A is moved downwards, reducing the effective resistance r, and consequently the motor M runs more slowly. In a modification, Fig. 2 (not shown), rollers which engage bights in the film on opposite sides of the roller V are mounted on an arm pivoted on the axis of the roller, which arm is connected at its outer end through a spring to the slider arm of the controlling resistance. In order to facilitate synchronism between the generator and the motor M when the film is started, it is preferable that reaction should take place, in such a manner that whilst the motor is running at a slower speed than that corresponding to the frequency of the generator the current supplied to the motor will retard the frequency of the generator. For this purpose, the said reaction may be provided by inserting the stator of the motor in the generator circuit in such manner that the self-induction of the stator influences the frequency of the generator. Two such arrangements are shown in Figs. 3 and 4, in each of which S is the stator of the motor, and G is a valve generator. A further arrangement is described, Fig. 5 (not shown), in which the generator is an ordinary buzzer, the frequency of which is mainly determined by the natural frequency of the contactspring. Specification 249,627, [Class 40 (ii)], is referred to.

Title: Improvements in or relating to the recovery of sulphur from gases containing hydrogen sulphide
Inventor: MARSH JOHN DAVID FRANCIS
IPC: C01B17/04
Filed: 1953-12-02
Abstract: Sulphur is recovered from gases containing hydrogen sulphide (preferably 50 per cent by volume) in a process, similar to the Claus process, which comprises burning the gas in a combustion chamber in the presence of a controlled amount of air, partially cooling the resulting gas mixture, preferably to a temperature above the dew point of sulphur, passing the resultant gas mixture of hydrogen sulphide and sulphur dioxide through a single catalytic reactor, containing two or more layers of catalyst, at a preferred temperature of 300-400 DEG C. and finally condensing the sulphur, characterized in that sulphur free gases leaving the sulphur condenser are recycled between the catalyst layers so as to control the temperature of the gases leaving the reactor to just above the sulphur dew point. Additionally the sulphur free gases may be also recycled to the process gases before they enter the catalytic reactor: Before discharge to the atmosphere the sulphur free gases may be treated for the removal of the last traces of hydrogen sulphide by the method of Specification 769,996.  An automatic analyser as described in Specification 769,997 may be used to control the air for combustion relative to the hydrogen sulphide/sulphur dioxide ratio in the recycle gases. Specification 722,038 also is referred to.
