Title: Improvements in and relating to the removal of scale from metal bars or plates
IPC: B21B45/04
Filed: 1927-07-08
Abstract: 297,526. Williams, S. July 8, 1927. Cleaning.-In a process for removing scale from metal, bars and plates, &c., the bars &c. are mounted on a table so that all surfaces are exposed, and water is delivered on to the bars &c. in the form of a spray or sheet which moves across the table with a varying trajectory. The bars &c. are fed on to the table 12 supported by brackets 13 on a tank 10 and provided with an abutment 17 and an adjustably mounted ledge 18 so that they take up the position shown in Fig. 9 whereby all surfaces of the bar &c. will be exposed to the water or scale removing fluid projected thereon from a slotted pipe 30 mounted in a supply tank 26. The pipe 30 provided with a horizontal slot 31 is secured to a pipe 28, inside the tank, controlled at its inner end by a spring-controlled hinged flap 29 provided with an arm 32 secured to a link 33 connected at its upper end to one arm 35 of a lever 36 fulcrummed on the wall of the tank. A second link or a chain 37 is connected to the other arm of the lever 36 and also to a lever 38 one end of which is secured to a pin 39 which engages the spindle 40 of a roller 20. The spindle of this roller is carried by the end of levers 21, 22 which are pivotally mounted on a rod 23 extending through both walls of the tank 10, the lever 22 carrying a counterweight 24. When the bar, before being fed on to the table 12, is placed on the roller 20, the latter is depressed against the action of the weight 24 and pulls down the lever 38 thus raising the arm 33 and opening the flap 29 allowing water to flow into the pipe 30. The water will then be projected through the orifice 31 on to and across the table, the trajectory of the sheet of water varying so that it will first strike the rear end of the table and then pass over the whole of the table. If the supply of water is insufficient the lever 36 is provided with a handle so that the apparatus may be manually operated. Alternatively a foot pedal may be provided for the same purpose. In a modification the ledge 18 on the table 12 is dispensed with and the edge of the table turned up to form a stop and the valve flap 29 is arranged horizontally, being kept in position on the end of the pipe 28 by a spring.

Title: Improvements in and relating to cyclic overlap electric rectifier switching mechanism
IPC: H02M1/26
Filed: 1952-07-18
Abstract: 717,376. Fluid actuation of switches. GENERAL ELECTRIC CO. July 18, 1952 [July 18, 1951],  No. 18229/52. Class 38(5). A cyclic overlap rectifier switching mechanism comprises a series of separate fluid-operated switches and a multi-port rotary valve for applying the fluid to the switches successively in such a way as to close the next switch before opening each switch. In one form, six switches 13a - 13f are arranged around a hexagonal body 10 having cylinders containing operating pistons 11a-11f. The valve 12 is driven synchronously by an A.C. motor and has a port 12c leading from the fluid source 54 to an axial bore 12d and thus to a radial bore 12a which is brought opposite each cylinder in turn to operate the pistons successively. An exhaust port 12b arranged 150 degrees behind bore 12a ensures that, when e.g. piston 11e is actuated, pistons 11c, 11d remain actuated, 11c only being restored after a further 30 degrees rotation from the position shown in Fig. 2. The port 12b leads to a drain hole 53 via a cavity 52 in the body 10. Each moving contact 23 co-operates with fixed contacts 16, 17 connected respectively to the A.C. and D.C. conductors. The contact 23 is carried on an insulating block 25 cooperating with a shock-absorbing buffer 26, the contact being guided by a pin 29 and a member 31<SP>1</SP>, and restored by a spring 32 having an adjustable stop 33. In a modification, Fig,. 15, (not shown), each contact 23 has a separately adjustable stop threaded into body 10 to limit the opening movement. The fluid pressure may be varied to retard or advance the initial closure of the contacts and the body 10 and valve 12 may be relatively adjusted to advance or retard the termination of the contact closure. In a modification, Fig. 5, the valve 72 has three angularly and axially spaced radial bores 81 each co-operating with two switches, such as 71a, 71b co-operating with fixed contacts 75, 76, 77. Each contact remains closed during 150 degrees rotation of the valve until the fluid exhausts at 83. the other contact being closed after a further 30 degrees rotation. In a further arrangement, (Fig. 9, not shown), the six switches are arranged in one line along the axis of the valve which has six axially and angularly spaced inlet ports and six similiarly spaced exhaust ports.

Abstract: 497,966. Centrifugal separators. AHLMANN, N. Ju]y 1, 1937, No. 18374. [Classes 23 and 117] Powdered materials are separated from each other while travelling in an helical path along the inner surface of a container by a number of jets of air which carry the fine particles towards the axis while the heavy particles are held on the wall by centrifugal force. A conical part 9 is arranged below the cylindrical part 2 which is surrounded by a chamber 6 to which air under pressure is supplied through the connection 14. A disc 3 on the shaft 15 carries vanes 4, 5, the latter being extended by perforated vanes 19. The powdered material is supplied through the inlet 1 and its passage is assisted by a screw. It drops to the rotating disc 3 from which it is thrown to the wall and it travels downwards in an helical path assisted by the vanes 5. Air from the chamber 6 blows in through inclined slots 7 and carries the fine particles to the central outlet 10 which is connected to a cyclone separator 12. The fan 13 withdraws clean air from this separator and passes it to the inlet 14. The heavy particles drop from the container 2' to the discharge valve 11. In a modification the cyclone separator is combined with the main separator and mixture enters at the bottom instead of the top. Specification 457,541, [Group XIII], is referred to.

Abstract: 1,126,118. Valves. T. OTTONELLO. 29 April, 1966, No. 18892/66. Heading F2V. In order to prepare a gas burner supply valve arrangement for operation a knob 22 is rotated to screw a shaft 17 into engagement with a diaphragm hub 10 to align the locking pin 19 of a push-rod 12 with slots in a member 16 and the shaft 17; the diaphragm 1 defines two chambers 3, 4, open to the throat of a twopart Venturi 5 in a water system to be heated by the burner, and atmosphere, respectively. The Venturi has an adjustable inlet throttle. Upon depressing the rod 12 it abuts a further rod 11 and unseats a spring-loaded discclosure 13 to allow gas flow to a pilot burner 51 ; the pilot flame heats a thermo-couple 15 which energizes a solenoid 14 that holds open the Closure 13 and enables the rod 12 to be released. The shaft 17 may now be rotated to lift it from the diaphragm 1 whereupon any flow of water in the system causes a pressure drop across the Venturi and hence in chamber 3, the resultant upward movement of the diaphragm opening a closure member 7 to supply gas to the main burner. The gas flow is controllable by rotation of knob 22 whilst upon failure of the water supply a spring 38 seats closure member 7. In a modification, the solenoid valve control knob and push-rod are dispensed with.
