Valve chests, cooling; exhaust, cooling and dealing with.-In a power plant comprising a combustion cylinder, in which gas or oil is burnt for the production of motive fluid, and a prime mover in which the motive fluid performs work, the combustion cylinder is provided with an exhaust valve 5 of the mushroom type, the transfer of heat to the walls of the valve chamber 1 being minimized and the valve seat 9 or the valve being cooled directly or indirectly by means of compressed air or gas which is subsequently used as motive fluid. The plant may be similar to those described in Specifications 232,278, 244,215, and 245,541, the combustion cylinders driving a compressor which supplies the compressed air or gas and may also supply scavenging air to the cylinder. As shown, the valve chamber 1 is provided with a sleeve 7 and an extension 10, around which flows compressed air from one or more inlets 11. The air passes through apertures 12, adjacent to the valve seat, to mix with the exhaust gases escaping past the valve 5, and may also pass through apertures 15 in the valve guide 3 and apertures 13 and grooves 14 in the valve stem 4 or the guide. In modifications, the valve seat itself is provided with slots through which the air passes. or the lower end of the sleeve 7 is shaped to direct the air on to the valve seat, fins being provided on the end of the sleeve to position it in the chamber 1. As the sleeve 7 and extension 10 are subject to similar pressures on both sides, they may be constructed of refractory material or of one or more layers of metal coated or lined with refractory or heatinsulating material. The compressed air may be first utilized to abstract heat from the exhaust or other parts of the prime mover component or cylinder head jackets of the combustion cylinder.

Filed: 1956-07-12
Abstract: 826,034. Centrifugal strainer separators. ESCHER WYSS A. G. July 12, 1956 [July 12, 1955], No. 21579 /56. Class 46. [Also in Group XXXVII] A continuously-fed push-type centrifuge having a rotary straining drum 2 and a rotary distributing funnel 3 driven by an electric motor 6 through a belt drive 5 is fed with material from a container 8 through a pipe 10. A throttle valve 11 controls the amount of material supplied and is adjusted by a second motor 15, which is actuated in accordance with the power input to the motor 6, and which drives a screw 16 engaging a nut 17 at the end of a lever 14 to which the valve 11 is connected. The second motor 15 is fed from the mains 18 by leads 19 and 24 the direction of rotation of the motor depending upon the connection of lead 24 with a conductor 23 or 25 through a contact arm 20. The contact arm 20 is attached to a beam 26 whose position is influenced by two electromagnets 27, 28. The electromagnet 27 is fed by current from one of the conductors 7 leading to the motor 6 while the electromagnet 28 is fed from the mains 18. In operation if the feed of material to the centrifuge increases, the power input to the motor 6 also increases and thus the current to the electromagnet 27 increases causing the beam 26 to turn clockwise until the arm 20 connects the lead 24 and conductor 23 and the motor 15 rotates to move the throttle valve 11 to decrease the supply of material to the centrifuge until the power input to the motor 6 decreases to its predetermined value when the arm 20 resumes its neutral position. If the supply to the centrifuge decreases the arm 26 turns in an anticlockwise direction and the motor 15 rotates in the opposite direction to move the valve 11 to increase the supply of material. A rheostat 30 is provided to control the current to electromagnet 28 which determines the steady rate of flow of material to the centrifuge.

Title: Improvements in and relating to the treatment of glass
IPC: C03B29/08
Filed: 1964-05-26
Abstract: The major surfaces of a glass sheet are exposed to currents of a relatively cold fluid to retard heating of the surfaces while radiant heat sources facing at least one of the surfaces raise the interior temperature of the glass to above its annealing point and approaching its softening point.  In one embodiment glass sheets suspended vertically by tongs 18, Fig. 2 (not shown), are conveyed through a heating furnace 10 and a tempering furnace by a monorail. The side walls 44, 46 of the heating furnace carry radiant heaters 46 opposing the major faces of the sheet.  A cooling fluid, e.g. gas, is supplied from a burner 62 and passed through a conduit 68 and passage 54, 48 into the upper part of the furnace 10, the gases circulating downwardly past the sheet faces and exhausting through a passage 58. Means are provided to cause reciprocatory motion between the sheet and the heaters 46.  The gases at a temperature of 1120 DEG  F. are passed continuously during the heating of the sheet.  In a further embodiment a sheet G is supported upon a skeleton bending frame 73, Fig. 5 (not shown), and conveyed through two heating zones 102, 104, a bending zone 106 and a tempering zone 108, Fig. 4 (not shown).  The tunnel furnace of the three zones has radiant heaters 76 in the upper and lower walls 79 and burners 80 in opposed walls 77, 78 but vertically displaced relative to each other.  The burners thus supply currents of relatively cold gas across and parallel to the major surfaces of the sheet G. The cooling gas is supplied to zone 102 at 1300 DEG  F., zone 104 at 775 DEG  F. and the bending zone 106 at 1100 DEG  F.  A similar type of furnace may be employed wherein flat sheets are horizontally conveyed therethrough to be pre-heated prior to having a film coating applied to one or both surfaces followed by bending, annealing or tempering.  The glass sheets may be heated by the radiant heaters to just below their strain point (e.g. 50 DEG  F. below) before applying the cooling gas.
