Title: Improvements in and relating to means for the automatic control of furnace dampers and the like
IPC: F23N3/02
Filed: 1922-02-14
Abstract: 190,665. Craig, W. Feb. 14, 1922. Fluid-actuated valves. - For regulating the damper of a furnace or other damper-controlled chamber in accordance with the pressure therein, the damper 1 is directly connected to a " motor " which is mounted on top of a tank containing the draught or pressure controlled float 30. A rod 29 axially secured to the float is connected directly to a piston-valve 19<a>, which forms part of the connection to the float-counterweight 23, and the position of which determines the position of the power piston 8, the arrangement being that the interior of the cylinder, which is exposed to water pressure, connects with the valve chamber through a number of small holes 19 so that the piston 8 always takes up a position with its upper edge below the lower end of the valve to an extent just sufficient to allow a small escape of water. The escaping water fills a shallow container on top of the float chamber and the leakage round the loosely fitting rod 29 maintains the level in the float chamber. The float has a buoyancy chamber 27<a> and both it and the piston 8 are appropriately balanced by counterweights 23 and 4 respectively.

Abstract: 1293463 Orientating articles on endless conveyers A DOMINICI 29 Jan 1970 [3 Feb 1969 18 July 1969] 4389/70 Heading B8A A device for aligning and orienting articles comprises: a continuously operating conveyer 4 receiving the articles in batches from an intermittently operating feed conveyer 2; movable spaced barrier means 8 moving transversely at the leading end of said continuous conveyer and obstructing it during the transfer of one batch from the intermittent conveyer, the gaps moving transversely across the width of said continuous conveyer once the transfer is completed, to permit the articles of the batch to pass in single succession through the gaps; first movable guide means 9 behind the barrier means on the continuous conveyer and placed at an angle to its motion, to space apart the articles arriving through the gaps; check means 11 to preliminarily orient the articles with their longer dimension parallel to their direction of travel; additional orienting means 12 to accurately orient the articles in the direction of travel and convey them to an output channel. As shown in Figs. 2, 3, and 5 the barrier means comprises groups of members 8 carried by an endless member 5. The distance of the members 8 from the inlet end of the conveyer 4 is such as to leave, between said end and the barrier, a space just sufficient to contain one front row of articles. The means 12 comprises an endless belt 12, the plane of which is vertically disposed. Co-operating with the belt 12 is a further endless belt 14. The intermittent drive for the conveyer 2 comprises a ratchet driven drum (37) (Fig. 1, not shown) operated by a spring- loaded chain (35) deflected by a cam and lever mechanism (30), (31). In a modification (Fig. 7), the barrier is formed by a flexible band 123 which is fixed at opposite ends 124, 125. A movable gap is provided by passing the band 123 around vertical axis pulleys 121, 122 and horizontal axis pulleys 119, 120, all freely mounted on a movable carriage 114. The latter is traversed laterally with respect to the belt 4 by virtue of its connection to an endless belt 113. The latter is given oscillatory travel by a belt 134 driven by crank and cam mechanism 130, 128. The belt 113 carries two series of members 138. These provide a rigid backing behind the band 123 to resist the pressure of the articles.

Title: Temperature responsive control devices
IPC: H01H37/56
Filed: 1963-02-04
Abstract: 999,653. Automatic temperature control. ROBERSHAW CONTROLS CO. Feb. 4, 1963 [Feb. 28,1962], No.. 4493/63. Heading G3R. [Also in Division H2] A room thermostat has a spiral bimetal as its temperature sensitive element (see Division H2) which causes cycling on and off of a contact 308a in a switch 308 at the pre-set temperature of the thermostat. A double-pole, triple-throw, system control switch 405 has a slide actuator 407 with "heat", "off" and "cooling" positions, and a singlepole, double-throw fan-control switch 406 has an actuator 408 with "manual" and "automatic" positions. A relay 440 controls a heating circuit including an electrically actuated fuel control valve for a furnace, a second relay 445 completes a cooling system control circuit when energized and energization of relay 443 supplies power to a cooling fan which normally has a separate on-off switch in the circuit so that the fan is operable regardless of the thermostat setting. A separate fan control circuit could be provided to operate a heating fan in response to air duct temperature. As shown, for example the control switch 405 is in the "heat" position and the fan switch 406 is in the "manual" position, the circuit to heating relay 440 being completed in alternate positions of switch 308 and the fan circuit being completed in either position of switch 308 so that it is controlled only by its own on-off switch. Cooling relay 445 is off in either position of switch 308. A variable anticipatory heating resistor 316 is positioned near the bimetal element to allow for a lag in its reaching the ambient temperature set. With fan switch 406 in the "auto" position, both relays 443, 445, are off in either position of switch 308 if switch 405 is at "heat". Fig. 18, and Figs. 19-23 (not shown), show all six possible combinations of the positions of switches 405, 406. A resistor 421, when in circuit, acts as a cooling system heat anticipator for the bimetal elements.

Title: Improvements relating to apparatus including thermionic valves
IPC: H05K7/20
Filed: 1945-02-26
Abstract: 588,517. Wireless receiving sets. BRITISH THOMSON-HOUSTON CO., Ltd., and MELVILLE, W. S. Feb. 26, 1945, No. 4738. [Class 40 (v)] The components of an electronic apparatus which do not generate substantial heat are enclosed in a sealed easing ; and the valves and other heat-generating components are enclosed in separate containers sealed to an outer face of the casing and provided with heat-dissipating means. The variable-control and indicating components are enclosed in a separate chamber mounted on a wall of the casing through which pass the necessary loads. On the sealed casing formed by base 1 and lid 2 are mounted and sealed by means of flanges 6, containers 4, 5. The containers enclose a heatgenerating component (for example a. valve), and included in them is a sleeve mounted be. tween the component and the container, and having apertures which promote convection currents for dissipation of the heat generated. Connections to apparatus external to the sealed casing are made by glass sealing of the leads 11 into eyelets welded around apertures in the casing. The manual control means 9, 10 for the apparatus are mounted in a separate chamber 8 which is sealed in known manner to the casing and which surrounds the appropriate sealed leads 11. To enable the replacement of faulty valves without interference to the sealing of the casing, the valve sockets may be sealed to the casing in a manner similar to leads 11. Since mechanical connections are required to pass through the wall of the chamber 8, it is difficult to render it gas-tight, this may be overcome by providing the chamber with a breather which allows the atmosphere entrapped within the chamber to expand and contract; a dessicator may also be used. To avoid leakage of moisture into the casing it may be filled at pressure with dry air or neutral gas.
