Title: Improvements in heating systems employing hot circulating liquids
IPC: F24D3/02
Filed: 1942-08-20
Abstract: 559,250. Heating by hot circulating liquids. KOCH, E. A. J. Aug. 20,1942, No. 11712. [Class 64 (ii)] In a heating system in which hot liquid is circulated from a generator a through a pump c to a heat utilizer d and back to the generator, the delivery pressure of liquid to the apparatus d is stabilized by bleeding back into the generator the flow beyond the pump at such a rate that the pressure and/or temperature of the liquid delivered to the apparatus d is kept constant. The control of the bleed pipe e is effected by a valve f controlled by the pressure of the liquid acting on a piston h, the pressure being kept constant. The liquid passes through a superheater i between the pump and the bleed point, and the amount of available superheat is limited to that corresponding to the pressure at the apparatus d. This may be done in known manner by controlling the flue gases, introducing cold return water into the suction of pump c, or controlling the speed of pump c.

Abstract: 244,334. Sibley, E. J. May 6, 1925. Stays.-A telescopic casement stay comprises a tube and a plunger therein, friction means interposed between these parts, and means for adjusting the friction to a predetermined minimum degree by rotation of the tube. As shown, the friction means consists of semi-circular shoes 16, 17 between which is a flat spring 18, one of the shoes 17 being screw-threaded at 22 for engagement with the screwed end of a plunger-rod 12. The member 16 supports one end of the spring 18 and has a non-threaded recess 21 for receiving the end of the plunger 12. The friction of the shoes is adjusted by rotation of the tube 1, one end of which is rotatably mounted at 2 on a short arm 3 pivoted at 4 to a bracket 5 secured by a screw 7 to the window sill. The longitudinal adjustment of the member 17 caused by rotation of the tube is limited in one direction by a lug 41 abutting the end 33 of the recess 19, and in the other direction by the end of the screwed thread 22 contacting with the end of the screw 15. The friction of the device is adjustable between the limits of maximum and minimum flexing of the, spring 18, as affected by the position of the lug 41 on the shoe 17. The arrangement of the relatively movable friction shoes and intermediate spring is also described as applied to a telescopic stay in which the adjustment of the friction shoes against the tube is required to be effected before assembling the parts on the window and its frame.

Abstract: 1354425 IGFETS ITT INDUSTRIES Inc 16 March 1972 [19 March 1971] 12349/72 Heading H1K In making an IGFET a first insulating layer is provided on a semi-conductor wafer at the device site and a second insulating layer elsewhere, then semi-conductor material is deposited over both layers and oxidized throughout its thickness at the source and drain sites. The oxidized semi-conductor and underlying insulation is then removed, dopant diffused into the areas thus exposed to form the source and drain regions, and ohmic contacts provided thereto and to the semi-conductor gate. As described the wafer is of 111 oriented 40hm.cm.N-type silicon. Silicon nitride is initially deposited and then restricted by etching so as to mask the device during oxidation of the rest of the wafer face. After levelling the treated surface by removal of the nitride and some oxide the hitherto masked surface is oxidized to provide gate insulation. Polycrystalline silicon is then pyrolytically deposited overall and a nitride mask provided leaving exposed parts overlying the source and drain sites which are then converted to oxide and etched away together with the underlying oxide. After removal of the masking boron is diffused to form the source and drain regions and dope the remaining parts of the polycrystalline layer. Finally aluminium is deposited to ohmically contact the source, drain and gate via apertures in a deposited silica layer. If an N- channel FET is required a P-type wafer is used and the polycrystalline layer is diffused with boron while entire, and masked during formation of the source and drain by diffusion of phosphorus.
