Title: Improvements in boiler or other fluid heater cleaners
IPC: F28G3/16
Filed: 1939-07-26
Abstract: 532,693. Soot blowers. BABCOCK & WILCOX, Ltd. July 26, 1939, No. 21697. Convention date, Aug. 17, 1938. [Class 99 (ii)] In a boiler cleaner operated by a screw device arranged so that, when the driving-member is rotated in one direction, the blower tube is projected to its operative position and is then rotated, but is retracted when the rotation of the driving- member is reversed, the blower tube 73 is moved forwards by rotation of a square shaft 97 carrying an arm 105 with roller 106 working in a spiral 75, the roller 106, when the blower tube reaches its operative position, entering a notch 108 in a latch ring 107, which rotates freely with the blower tube as the shaft is rotated in the same direction. When, however, the rotation of the shaft is reversed, the ring 107 is held against rotation by a one-way detent, and the roller 106 returns into the spiral 75, so that the blower tube is retracted. In the operative position, ports 114 in the blower tube coincide with inlet ports 115 for the cleaning-fluid, while in the retracted position they co-operate with a cooling-fluid inlet 118. In a modification, the driving- shaft 97 is formed with a screwthread engaging a key on the blower tube, which is thus projected without rotation, the key entering a slot in the latch ring at. the end of the forward movement.

Title: Improvements in or relating to switching arrangements for radio receiving or transmitting apparatus
IPC: H02M1/14
Filed: 1945-08-24
Abstract: 620,749. Switching systems. GENERAL ELECTRIC CO., Ltd., and GARTHWAITE, F. N. Aug. 24,1945, No. 21774. [Class 38 (iv)] [Also in Group XL (c)] In a radio apparatus an electromagneticallyoperated switch connects the apparatus to the mains, and the coil of the switch is used for smoothing the current supplied to the apparatus. As shown, the rotary switch f is connected to the hour-hand of a clock and the rotary switch g is similarly connected with the minutehand, the contacts being adjustable so that the switches will close at any predetermined time. By this means the coil e of the electromagnetic switch may be connected across the mains terminals a and b to cause the plunger m to be raised against the action of the tension spring -w, disconnecting coil e and connecting the primary n of the transformer across the mains a, b. The plunger m is locked in its upward position by a common latch-bar o and at the same time the plunger l is forced downwards by the compression spring v and locked. This connects the coil e in series with the rectifier s and load r, and with the condensers u and t forms the smoothing arrangement, the switching being arranged to ensure that the secondary circuit is not broken during the operation. The push-buttons labelled " Time," " On," and " Off," enable the apparatus to be switched on manually with or without the clock switch in action.

Filed: 1922-08-12
Abstract: 206,602. Hostoch, F. J., and Moore, S. Bramley-. Aug. 12, 1922. Fluid-actuated valves.-A gas and air mixing- apparatus is provided with a gas inlet valve A and a mixture-delivery valve B either or both of which, when the mixing-mechanism, such as a fan or compressor, is inoperative, can be sealed by tappets D, E operated by a spring C<2> and, when the mechanism is in operation, released by diaphragms F<2>, F<3> secured to the tappets and operated by the pressure of the gas mixture in the delivery port B<1>. The gas and air are drawn by the fan through the port A<2> from the gas inlet A<1> and the atmosphere respectively, and the mixture is discharged at a slight pressure through the port B<2> to the service main. On the fan being started, the pressure on the outside of the diaphragm compresses the spring C<2> and so releases the tappet from contact with the valves. The delivery valve is automatically opened or closed when the pressure in the port B<2> falls or rises by the pressure of the mixture acting upon the diaphragm F<4>. In a modification, the diaphragms F<2>, F<3> and tappets are replaced by a single diaphragm and tappet, the latter being adapted to engage with both valves simultaneously by means of a rocker.
