Title: Improvements Applicable to Driving Belts.
Inventor: BOOTH GEORGE JAMES
Filed: 1903-06-10
Granted: 1903-10-08
Abstract: 13,008. Booth, G. J. June 10. Belts and bands. - To relieve the internal strains which are set up in thick compound belts when passing round d small pulleys, such as those use for driving motor bicycles or machinery, the layers a, b, Fig. 4, of leather, woven fabric, or other material, are separated by distance - pieces d, which are tapered in section, and are secured to the layers a, b by means of screws, or rivets, or by stitching. For V-grooved pulleys, the inner layer b is narrower than the outer layer, and the pieces d are tapered to fit the grooves. The invention is equally applicable to flat belts, and two or more layers may be used. In operation, the inner layer enters the spaces between adjacent pieces d as the belt passes round the pulley.

Title: Improvements in Pressure Reducing Valves.
Inventor: ATKINSON CYRIL JOSEPH
Filed: 1903-06-12
Granted: 1904-03-17
Abstract: 13,144. Atkinson, C. J. June 12. Pressure-regulating valves; actuating valves.- The valve is contained in a casing a and may be a double-beat valve or a single mushroom valve b, in either case, being the spindle. In a projection d from the casing a is pivoted a lever e, on which are mounted chambers f, g of equal capacity and weight, and arranged as shown. The two chambers are connected together by a pipe i and one of them g is connected by a pipe j with the low-pressure side of the valve. A quantity of mercury sufficient to fill one of the chambers is contained in them. The high-pressure steam &c. normally acts to open the valve and a portion of the steam passes through the pipe j to the chamber g and forces a quantity of mercury up into the chamber f causing the adjoining arm of the lever e to descend and to force down the spindle b and thereby close the valve and hold it closed. When a reduction of pressure in the chamber g takes place, mercury flows back into that chamber, thereby causing the lever e to be raised off the spindle b. A weight may be placed on the lever to assist in regulating the pressure on the low-pressure side.

Inventor: RAMAGE ALEXANDER SYDNEY
Filed: 1903-07-23
Granted: 1903-10-22
Abstract: 16,302. Ramage, A. S. July 23. Food preparations.-Whey, to which milk (preferably skim-milk) may be added, is treated so as to precipitate the proteids, lactalbumin and lactoglobulin, with or without lactose. It is made slightly alkaline by a suitable agent, and may be concentrated in vacuo to one third of its volume. On cooling pure alcohol is added, when the proteids are precipitated without lactose. They are removed, washed with alcohol, and dried in vacuo forming a soluble food suitable for invalids and children. To obtain lactose or milk-sugar in the product, the concentration is carried further, the amount obtained varying as the concentration. When skim milk is added to the whey, caseinogen is obtained with the other products.

Title: Improvements in Pianofortes for Normal and Practising Play, applicable also to other Practising Keyboard Devices.
Inventor: ROBERTSON ROBERT BARBOUR
Filed: 1903-09-11
Granted: 1904-07-14
Abstract: 19,629. Robertson, R. B., Rushworth, W., Rushworth, E., and Rushworth, A. L. Sept. 11. Exercising-apparatus; pianofortes.-Pianofortes adapted for both normal and practising play, as described in Specification No. 17,982, A.D. 1902, and other practising keyboard devices, are provided with strikers C for audibly indicating the striking and the release of the keys, when the keys are depressed or released in a brisk manner. This is effected by giving play or movement to the strikers after a key is fully down or up. Two oppositely-acting springs D, E for the striker C keep the striker normally well away from the striking indicator F and nearly against the release indicator G. The release indicator is fixed, but the pivoted and padded bar M may be brought into contact with the striking arms C to hold them out of action, partly or completely. The disengaging bar M may be worked by means of a slide. The striking indicator F is hinged and padded and can be turned into any one of several positions by means of a stepped slide. The tension of the keys is preferably varied by the means described in Specification No. 17,982, A.D. 1902, but the tension operating lever is connected to the slide of the release indicator so as to put the release indicator out of action when the lever is moved to apply a tension greater than a certain amount. The musical playing action of the pianoforte is lifted vertically from the keys by means of a foot pedal when it is desired to silence the pianoforte. Two sets of striking arms, one for the striking indicator and the other for the release indicator, may be employed.

Abstract: 27,537. Wood, H. I. Dec. 17, A.D. 1903, . [date applied for under Patents Act, A.D. 1901]. Vacuum tubes.-The exhausted envelope of a vapour electric apparatus consists of a tubular portion 1, preferably inclined or horizontal, through which the discharge takes place, and a short vertical portion 2 which serves as a condenser. At the end of the portion 1 is a hollow graphite or carbon electrode 3, connected to a leading-in wire. A glass tube 5 protects the wire and is flared to fit over one end of the electrode 3. The other end of the apparatus is provided with two pockets 6,7 containing mercury. A filament 8 of carbon is connected to the electrode 3, and rests at its other end, which is enlarged to counteract disintegration, on the surface of the mercury 6. Intermediate supports 9, 10 are provided. When the lamp is switched into circuit, currents flow through a steadying-resistance 15, electrode 3, and filament 8, to the mercury 6, and through electromagnet 12, and switch 21. The field of the magnet causes the filament to lift from the surface of the mercury, striking an arc, which is blown across to the mercury 7 and travels along the filament to the electrode 3. Immediately the current passes through the electrode 7, the switch 21 is opened by a solenoid 16, cutting the electrode 6 out of circuit. Two separate electromagnets in parallel may replace the electromagnet 12, one serving to displace the filament and the other to displace the arc. One mercury electrode only may be used, the filament being allowed to rest on its surface when the apparatus has been started.

Abstract: 10,895. British Thomson-Houston Co., [General Electric Co.]. May.24. Switches. - In alternating - current induction motors, especially such as are provided with fly-wheels to take up variations in the load, the current taken by the motor is limited to a predetermined value by automatically controlling the resistance in the motor circuit by means of a switch operated by two auxiliary motors, the torques of which respectively depend upon the voltage and current supplied to the main motor. The resistances R', R', R<3> in the rotor circuit of the main motor M are controlled by electromagnetic switches 1 ... 9 under the control of the switch K, which is normally held in its 'off' position by a spring K<1>. The two auxiliary motors m<1>, m<2> are so proportioned that, with normal current flowing to the main motor M, the motor m', which is connected in shunt with the motor M, has greater torque than that of the motor m<2> and the spring K<1> combined, and tends to rotite the switch to cut out resistance. The motor m<2> is supplied with current from the series transformer A<3>, B<3>, C<3> and tends to rotate the switch to introduce resistance. The magnetic switches 1 ... 9 may be omitted and the resistances controlled directly by the switch K.
