Filed: 1938-12-28
Abstract: 521,886. Pressure gauges. TCHANG, T. L., and RETEL, J. M. R. Dec. 28, 1938, Nos. 37623 and 37624. Convention dates, Dec. 28, 1937, and Nov. 23, 1938. [Class 106 (ii)] Comprises apparatus in which the pressure to be measured acts upon one face of a sensitive device which is subjected on its other face to an adjustable and known opposing pressure, this apparatus comprising supports with which the sensitive device can make contact at points distributed over its surface after a predetermined deformation. A body 1 similar in shape to a sparking plug is screwed into the head of a cylinder, and contains the diaphragm 2, the edge of which is clamped with an interposed insulating ring 3 between abutment plates 4, 5. The plate 4 seats on the bottom of the body 1 and is provided with a series of concentric ribs 6 between which are holes for the passage of cylinder gases to act on the diaphragm, radial passages 8 being provided. The surface 5 is provided on its lower surface with an analogous arrangement. An annular groove around the plate 5 gives it elasticity which permits compensation for thermic expansion. The plate 5 is secured to a rod 10 concentric with a frusto-conical sleeve 11 fixed in the body 1 by a ring nut 12. An insulating washer 13 is located between sleeve 11 and member 5. On the sleeve 11 is a hollow connection 14 having a tube 15 for feeding the gas at known pressure. The rod 10 projects beyond the sleeve and is fitted with a cap 18 separated from the sleeve by an insulating washer 19. A terminal 20 connects the cap with an electric circuit comprising a battery, the primary of a transformer and the metal work of the framework. The secondary of the transformer is in circuit with a neon lamp. As long as the known regulated pressure is lower than the maximum pressure in the cylinder, the membrane is moved off the plate 4 and breaks the primary circuit causing the neon lamp to light up. As soon as the applied known pressure equals the maximum pressure in the cylinder, the lamp fails to light up. A pressure gauge on the gas supply means indicates this pressure. Instead of a membrane a thin disc or light piston moving between plates 4 and 5 may be used. The parts may be made of non-magnetic metals to avoid steel particles becoming fixed to them and affecting their operation. The gas conduit is partly throttled by a rod 31.

Filed: 1961-10-23
Abstract: 1,005,312. Hydraulic control apparatus. H. A. SCHLATTER A.G. Oct. 23, 1961 [Oct. 26, 1960], No. 37845/61. Heading F1P. [Also in Division B3] Control apparatus for a flash-butt welding machine having at least one hydraulic ram for forward feed of the work comprises a main valve controlling a conduit from the ram return space to an outlet, a hydraulic fluid pressure operated cylinder and piston device operatively connected to the main valve for forcing it on to its seat, and conduit connections for the cylinder by which its working space can be connected to a source of hydraulic fluid pressure. A pair of pistons 3, 4 in cylinders 1, 2 are connected to the movable carriage of the welder, the working spaces 7, 8 communicating through a conduit 9 with a cylinder 10, the larger face of the differential piston therein being connected to a supply of compressed air or to atmosphere by a magnetically-operated valve 17 and the conduit 9 and the smaller face of the piston being connected to a hydraulic fluid source through a magnetically operated valve 13 and non-return valve 12. The return spaces 23, 24 of cylinders 1, 2 communicate through a conduit 25 with a device 20 including a main valve 22 connected to a piston 21 in a cylinder 20a in turn connected to a piston 37 in a cylinder 20b. The conduit 25 is connected to a slow discharge conduit 35 and via the valve 22 to a low pressure discharge conduit 32. The working space of cylinder 20a is connected through a magnetically-operated valve 27 with the conduit 25 or with the space 31 in contact with conduit 32. In operation hydraulic fluid is supplied through valve 13 to cause pistons 3, 4 to slowly advance the work during flashing, the fluid in spaces 23, 24 discharging through conduit 35. The said fluid acts on the valve 22 and through conduit 28 and valve 27 acts on the working face of piston 21 which has a larger effective area than that of the valve and so retains the valve closed. The valve 17 is operated to supply air to the large face of the differential piston in cylinder 10 which causes extra pressure to be applied to pistons 3, 4. The valve 27 is operated to place the working space of cylinder 20a in communication with the space 31 and valve 22 is thus moved rapidly to the left so that the work parts are rapidly abutted when fluid from spaces 23, 24 escapes to conduit 32. After welding hydraulic pressure is supplied via conduit 33 to return the pistons 3, 4 and compressed air is supplied to cylinder 20b to return valve 22.

Abstract: 808,034. Supplying oil to burners. CLEAVER-BROOKS CO. Dec. 13, 1956 [Jan. 18, 1956], No. 38065/56. Class 75(1) An oil fired burner system comprises a pump 20 supplying oil under pressure from a storage tank to a burner 10, a control valve 14 between the pump and the burner, a pressure relief line 24 including a pressure relief valve 23 connected to the supply line between the pump and control valve 14 and leading to the tank, a heater 25 interposed between the pressure relief line 24 and the control valve 14, a pressure reducing valve 36 between the heater and the control valve, an oil recirculation line 41 leading from the inlet of the control valve 14 to the tank and a restrictive orifice in the recirculation line 41 for limiting the flow to a value less than the capacity of the heater. The restrictive orifice is provided in the gate of a gate valve 42 in the recirculation line 41. A manually adjusted back pressure valve 43 in the recirculation line 41 between the gate valve 42 and the tank controls the flow of oil through the gate valve. The heater 25 includes an electrical heating element 27 controlled by a thermostat 28 connected in the supply line 26 leading from the heater. The heater is also supplied with steam heat through a conduit 29 controlled by a thermostat 31 associated with the heater. The control valve 14 may funcion automatically in response to burner demand to regulate the oil flow to the burner. A solenoid valve 16 is connected between the control valve 14 and the burner and is controlled to open and close automatically in response to burner demand. Opening of the solenoid valve 16 is prevented until the oil has reached a predetermined temperature by a temperature interlock 45 in the recirculation line 41. A by-pass line 47 provided with a by-pass valve 48 by-passes the pressure reducing valve 36, the control valve 14, the gate valve 42 and the back pressure valve 43 and is used to circulate the oil through the heater when the system is full of cold oil. Air is supplied to the burner nozzle through a line 11 and air for cleaning the oil supply lines between the solenoid valve 16 and the burner is supplied by a conduit 18 having a check valve 17. In a modificattion the by-pass line 47 is not provided and the back pressure valve 43 in the recirculation line 41 is replaced by a solenoid valve which at starting is open to allow circulation of the oil. When the oil reaches a predetermined temperature a temperatture interlock located between the heater and the pressure reducing valve 36 closes the solenoid valve in the recirculation line 41 and opens the solenoid valve 16 leading to the burner. The pump and heater may be interlocked with solenoid valve 16 and when the solenoid valve 16 closes the solenoid valve in the recirculation line automatically opens.
