Abstract: 512,982. Trollies. HOME COUNTIES TARMACADAM CONTRACTING CO., Ltd., and HACK, G. E. Feb. 28, 1938, No. 6208. [Class 108 (i) ] A vehicle is furnished with travelling wheels or rollers, and a further wheel or roller or a plurality thereof, which may be caused to contact with the peripheral surface of a container carried by the vehicle and which by movement imparted to the vehicle may be rotated and thereby effect rotation of the container in order to discharge its contents through a bunghole or other form of opening in its side. As shown, the vehicle is a hand-trolley comprising substantially L-shaped side members 1 each formed at one end with a handle 2 and at the other end with a ramp 3 to facilitate rolling of a container 10 on the trolley. In addition to the travelling wheels or rollers 5 carried by an axle 4, wheels 9 are provided mounted on an axle 8 movable in slots 6 formed in brackets 7 on the members 1 so that by rocking the trolley about the axle 4 the wheels 9, through contact with the ground, are forced into contact with the container 10. Movement of the trolley then rotates the container through the wheels 9 into the required position for discharging its contents through a pourer device which passes between further rollers 11 adapted to assist the rotation of the container. Stops may be provided on the side members to locate the container in its proper position. For discharging bituminous emulsions or other bituminous composition or liquids from the container on a road or like surface, means may be associated with the trolley for regulating the rate of entry of air into the container for controlling the rate of discharge. The container may carry freelyflowing solid materials. It is stated that troughlike containers or other devices may be carried by the trolley.

Filed: 1927-03-07
Abstract: 267,506. British Thomson-Houston Co., Ltd., (Assignees of Huber, H. J. H.). March 10, 1926, [Convention date]. Switching-systems; feeder and and transmission line arrangements.-In a testing-arrangement for conductors adapted to be connected to a source of supply through a circuit-breaker, interlocking means are arranged to allow connection of the conductors to a testing bus only when the circuit-breaker is open. The conductors 1, 2, 3 of a three-phase cable 4 are arranged to be connected through a circuit-breaker comprising singlepole units 5, 6, 7 to supply conductors 8, 9, 10. The circuitbreakers 5, 6, 7 are opened and closed by means of a trip coil 18 and closing coil 19 through mechanism 16. The line conductors 1, 2, 3, are adapted to be connected either to a testing bus 25 by means of a switch 28 or to a grounding bus 24 by means of a switch 27, these switches being interlocked by a biased bar 29 so arranged that it is moved into the path of the operating mechanism of one switch when the other is operated, thus preventing simultaneous operation of the switches 27, 28. The trip coil 18 of the circuit-breakers 5, 6, 7 is energized from control busses 14, 15 by placing a switch 42 on its upper contact o. The closing coil 19 is energized through a relay 45 when the switch 42 is turned to its lower contact c, the circuit being broken at contacts 36, 39 unless both switches 27, 28 are in the open position. Switches 50, 51 in the circuits of relays 47, 46 are closed by the opening of the circuit-breakers 5, 6, 7. The switch 28 may then be closed by placing a switch 44 on its lower contact c operating the relay 47 over closed contacts 40 and thereby energizing the closing coil 35. When the switch 28 is closed, contacts 41 in the circuit of the trip coil 33 are closed, and this coil may be energized by placing the switch 44 on its upper contact o. The switch 27 is similarly controlled by means of a switch 43, trip coil 32, closing coil 34, and relay 46. The testing means shown comprises a voltmeter 48 connected to earth through a transformer, a high-potential source being connected to the testing bus 25. To locate the fault, a source of direct current may be connected to the testing bus. A voltmeter 49 by a decrease in its reading may give an indication that a fault to ground has occurred.

Abstract: 159,817. Christenson, O. L., and Hedman, B. A., (Assignee of Gisiko, K. I. M.). March 3, 1920, [Convention date]. Manures.-In the coking of coal or other fuels, the nitrogen present is recovered as ammonium chloride which contains a small quantity of phenols and is suitable for use as manure. In an example, salt and silica, finely ground and mixed into a pulp with water are spread uniformly on the fuel before it is coked. The ammonium chloride may be separated from the distillation gases either by cooling to a temperature just above that at which the water condenses, when the ammonium chloride is obtained in dry condition or by cooling and condensing all the products together and crystallizing the resulting gas liquor.

[Class 86.] Gases such as oxygen and acetylene are supplied through a pressure-balancing device c described in Specification 199,300, [Class 86, Mixing &c.], to service pipes e, f, which are connected by branch pipes g, h, g<1>, h<1>, to welding torches j, j<1>, the branch pipes to each torch being fitted with cocks i, k, and water-sealed or other safety devices l, m, so constructed that there is an equal loss of pressure in all positions of adjustment. The oxygen passes from a main a to the pressure-balancing device c through a regulator b and a chamber 1 containing a valve 2, which is operated against the resistance of a spring 5 by the pressure on a diaphragm 3 of the acetylene passing from a main d to the device c. If the pressure of the acetylene on the diaphragm 3 is lower than the pressure of the oxygen, the valve 2 remains closed and as no oxygen reaches the device c the passage of acetylene through the device is prevented.

A pasty organic detergent composition that is capable of being pumped and has a high content of organic detergent, e.g. 60%, is prepared by degassing an organic sulphuric acid semi-ester or organic sulphonic acid, subsequently neutralizing the semi-ester or acid with an alkali in a continuous flow mixer, withdrawing a smaller proportion of the mixture as finished product after the mixture has left the continuous flow mixer, and recycling the larger proportion of the mixture through a cooler and back into the continuous flow mixer. The ratio of withdrawn finished product to recycled product is within the range of from 1: 5 to 1: 30. Additives such as buffers, e.g. sodium citrate and preserving agents, may be incorporated into the organic detergent in the continuous flow mixer. The organic detergent may be the sulphuric acid semi-esters of (a) fatty alcohols having a chain length of 12 to 18 carbon atoms, (b) their 1-5 moles ethylene oxide condensation derivatives, (c) C12 to C18 fatty acid or fatty acid amide oxyethylation (1-5 moles) products; alkylaryl-sulphonic acids having up to 12 C. alkyl; olefin-sulphonates of C15 to C22; and mixtures thereof.
