Title: Improvements in and relating to automatic pressure regulators
IPC: G05D16/20
Filed: 1925-03-18
Abstract: 231,170. British Thomson-Houston Co., Ltd., (Assignees of King, T. T.). March 18, 1924, [Convention date]. Controllers, actuating.-In devices adapted to maintain pressure between upper and lower limits, the spring 14 normally intended to define the range is supplemented by springs 15, 24 which are independent and adjustable to vary the range of actuation. The motor producing a vacuum beneath the diaphragm 11 is cut off when contacts 31, 38 separate and cut in again when the pressure has risen to the upper level. As shown the motor is functioning and the descending diaphragm 11 is turning the lever 12 clockwise about its pivot 9, with the arm 13 moving to the right to straighten the toggle 25, 28 and bring the spring 24 past the dead centre, when the tip 34 engages the end of the bell crank latch 32 to knock it off and allow the switch to snap open. With the motor then open, a rise in pressure reverses the action and ultimately closes the switch. The adjustable spring 15 acting against the spring 14 is used to vary the upper limit of pressure, the spring 24, acting with it, varies the lower limit. The contacts 31 are kept up to their work by springs 39 round bolts 41 passing loosely through a framework as shown in Fig. 2.

Abstract: 434,879. Arc converters. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and TAYLOUR, H. H., c/o General Electric Co., Witton, Birmingham. March 8, 1934, No. 7422. [Class 39 (i)] An arc converter is provided with a liquid cathode, a wall 8, which separates an inner anode space from an outer condensing chamber, and with a member 9 which directs the vapour from the cathode into the condensing chamber. The uncooled wall 8 is provided with frustoconical portions 11, 12 which form a gutter from which condensate is returned through a pipe to the cathode. Liquid jackets 6, 7 are provided and the liquid is supplied to the jacket 7 at the bottom thereof. The quartz member 9 may be conical, and forms with a quartz ring 14 and the bottom of the container, a diverging annular nozzle through which vapour is directed at high velocity to the condensing chamber. The nozzle has the effect of raising the vapour pressure at the cathode and thus to increase the efficiency of the cooling thereof. The flow of vapour past the gap between the members 8, 9 withdraws gases from the anode space. Orifices in the member 9 prevent the pressure in the anode space becoming too low. A pipe 10 connects the condensing chamber to the vacuum pump.

Title: Improvements in web tensioning device
Inventor: PETERSON ALBERT LISTON
IPC: B65H23/08
Filed: 1958-03-10
Abstract: 838,892. Feeding webs. WOOD NEWSPAPER MACHINERY CORPORATION. March 10, 1958, No. 7619/58. Class 100(1) [Also in Group XXXIV] A web tensioning device for controlling tension of a running web between a machine using the web and a rotating supply roll of web material, comprises first means for imparting substantially constant tension on the web when the machine is using the web at a desired running speed, and emergency stop means for imparting a braking force automatically to the rotating roll in advance of a rapid slowing down of the machine. As shown, web 2 being withdrawn from a roll 1 passes around a roller 12 carried by a rotatable arm 11 urged towards a vertical position by a spring 14. Movement of the arm 11 about a pivot 13, caused by variations in web tension varies the setting of a brake valve 21 by rocking plate 23. For example, a reduction in web tension causes the valve 21 to open to supply compressed air to a cylinder 25 which increases the tension of a belt 28 engaging the roll 1, thereby increasing the braking force on the roll. Should the machine being supplied with web be required to stop suddenly an emergency stop button, not shown, is pressed, thus closing a stop button 54 (Fig. 3, not shown), which energizes a relay 52 (Fig. 3, not shown), to actuate a solenoid-operated valve 30, Fig. 2, which boosts the pressure of air supplied to the cylinder 25. The machine supplied is decelerated after a delay due to the time delay in operation of relays arranged in cascade. When the machine slows down a speed responsive relay 51 (Fig. 3, not shown), is opened, thereby de-energizing relay 52 which causes valve 30 to close. The boost pressure applied to the cylinder 25 is thus removed. The web tension is then controlled purely by the roller 12. Reference has been directed by the Comptroller to Specification 748,829.
