Title: Hydraulic and air operated relay valve
IPC: B60T13/58
Filed: 1972-02-11
Abstract: 1359117 Relay valves; tractor-trailer brake systems BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO 11 Feb 1972 [19 March 1971] 6519/72 Heading F2F A relay valve for controlling the application of the pneumatic brakes on the trailer of a tractor-trailer vehicle simultaneously with the hydraulic brakes on the tractor, comprises a combined inlet and exhaust valve 70 controlled by a piston 86 having a lower face exposed to an outlet chamber 62 which is in constant communication with an outlet port 66, the piston being urged by a spring 90 to a normal position in which the valve communicates the port 66 with the atmosphere while isolating an inlet port 64, selectively operable pneumatic means and hydraulic means being provided for moving the piston 86 downwardly into a position in which the valve communicates the port 64 with the port 66 while preventing communication with the atmosphere. The pneumatic means includes a pressurized air-receiving control chamber 100 located above the piston, and the hydraulic means is a cylinder 46 integrally formed with the chamber 100 and in which a piston 50 has an abutment 110 extending through the wall of the chamber to be operatively engageable with the piston 86. Means are interposed between the abutment 110 and the piston 86 for sealingly closing the passage when the relay valve is pneumatically actuated, and for graduating the actuating force of the hydraulic piston 50 when the relay valve is hydraulically actuated. As shown, the section 44 of the valve casing has inlet and outlet chambers 60, 62 provided with ports 64, 66, the port 64 being connected with a supply conduit 23 and the port 66 being connected to a tractor service conduit 36; the chamber 62 is, in the normal position of the valve, in communication with the atmosphere via port 94, chamber 96 bore 80 of the valve 70 which is urged by a spring 72 on to a seat 76, and a check valve 84. The extension 116 is engageable with the piston 86 and passes through a check valve 102 having a lip 106 forced into contact with a seat 108 by the spring 90 or by compressed air in the chamber 100. When the chamber 100 is charged with compressed air from a reservoir 18 and via a valve 24 and port 98, the piston 86 is moved downwardly so that the member 92 engages the valve 70 to move the latter off the seat 76 whereby the chamber 62 is sealed from atmosphere and compressed air passes from the reservoir to the line 36 connected with the trailer brake 26. Movement of the pedal 14 effects hydraulic operation of the tractor brakes through a master cylinder 12 and wheel cylinders 16, the piston 50 being subjected to hydraulic pressure and moved downwardly, such movement causing corresponding movement of the piston 86 to open the valve 70 to charge the tractor and trailer service lines 36, 32.

Filed: 1963-02-19
Abstract: 963,965. Measuring pressure electrically. INTERNATIONAL RESISTANCE CO. Feb. 19, 1963, No. 6655/63. Heading G1N. A transducer for measuring fluid pressure comprises a differential transformer whose core is subjected in part to the test pressure, whereby the permeability of their part is changed, to produce an output voltage from normally balanced winding. As shown (Fig. 1), two primary windings 28, 30 and two secondary windings 32, 34 are symmetrically wound and core 12 having equal central passages 14, 16 separated by a wall 18. The primary windings are connected in series aiding, and the secondary windings in series opposition, or vice versa, whereby the resultant output voltage from the secondary windings is zero. A fluid pressure to be measured is presented to the passage 14 so that the part core surrounding it is stressed, altering its permeability and producing an output signal from the secondary windings indicative of the magnitude of the test pressure relative to the pressure in passage 16. Annular grooves 24, 26 in the core 12 round the passages 14, 16 respectively improve the linearity of the relationship between output voltage and pressure change. A reference pressure may be applied to passage 16. In another embodiment (Fig. 4), the primary winding 60<1> and secondary winding 62<1>, 64<1> are wound on a bobbin 52<1>, fixed to the core 44<1> by an annular rib 52a, and covered by a sleeve 66<1> of magnetic material. A nut 68 is screwed on to the core at each end, with spring fingers gripping the sleeve 66<1>, so that rotation of a nut stresses that part of the core to produce zero output from the transducer at a predetermined pressure difference.

Title: A method for utilising waste heat from exothermic chemical reactions
IPC: F01K3/18
Filed: 1957-02-28
Abstract: <PICT:0848895/III/1> In exothermic reactions the hot gaseous or solid products are brought into indirect heat exchange with compressed air or other gas used as a reaction component, and the heated compressed air passes to a back pressure turbine which drives the air compressors and also, if required, an electric generator; a part of the warm exhaust air is returned to the reactor.  In a suitable apparatus, air compressed to about 5 atmos. is fed from compressors 1, to a preheater 2, and heat exchanger 3 to which is fed indirectly the hot gaseous or solid reaction products of a pyrites roaster furnace 6.  The hot compressed air expands and drives a back pressure turbine 4 which is coupled to the compressors 1 and an electric generator 5.  Part of the exhaust air is fed to the furnace 6 and part to the preheater 2.  The amount of air entering the furnace can be controlled in relation to the quality of the pyrites, whereby the SO2 content of the gaseous reaction product can be maintained at above 8% if necessary.  A number of furnaces may be fed from the turbine.  If necessary, an auxiliary furnace providing additional combustion gases may be used, and switched in automatically to maintain the turbine output of heated air.

Filed: 1940-04-16
Abstract: 542,593. Shock absorbers. STEVENS, A. H. (Cleveland Pneumatic Tool Co.). April 16 1940, No. 6886. [Class 108 (iii)] A dash-pot employing both air pressure and fluid friction checking means comprises two telescoping cylinders 10, 13, the inner 13 of which is spaced from the wall of the outer 10 so as to form an annular space 17. The cylinder 13 passes through packings 21, 22 in a head 18 held in place by a screwed cap 20 and furnished with fluid tight ring 24. The bottom of the cylinder 13 carries a piston 30 having ports 34 closed by an upper and a lower ring valve 37, 43, springs 36, 42 in some of the ports 34 bearing against the rings 37, 43 and tending to keep them away from the piston 30. Small ports 45 in the ring 43, and smaller ports 39 in the ring 37 prevent complete closure to fluid passage, and these ports are further connected together when the rings are up against the piston by grooves 46, 40 running round the piston. A port 47, closable by the ring 37, and a smaller port 48 connect the interior 59 of the cylinder 13 to the space 17. The centre of the piston 30 is fitted with an annulus 50 furnished with ports 52 closable by a sliding ring 53. Through the opening 51 of the annulus 50 extends a metering pin 55 fixed on the bottom connecting butt 11. The pin 55 has a parallel top portion 56 which merges into a conical portion 57 and finally becomes a larger parallel bottom portion 58, of the same diameter as the opening 51. Oil &c. is introduced through a top orifice 28, and after actuation to fill all the lower chambers with the fluid an air valve 29 is screwed in place and air under pressure pumped into the upper part of the cylinder 13. Small forces applied between the butts 11 and 14 result in fairly free passage of the oil through the ports 34, 47, 48 and the opening 51. A severe compressive force, however, will result primarily in increased compression of the air and then in the ring 43 being brought up against the piston 30, and the ports 52 being closed by the ring 53, the opening 51 being subsequently gradually closed by the progressively larger diameter of the pin 55 as the piston descends, till finally it is closed altogether by the portion 58, leaving then only the ports 45 as open passages. A severe expansive force closes the ports 34 and 47 by bringing the ring 37 down on the piston, leaving only the ports 39 and 48 between the space 17 and the remaining spaces 59, 60.

[Class 42(i)] [Also in Group XXXV] In apparatus for seam-welding thermoplastic sheet material, the work is moved in relation to roller electrodes supplied with pulses of high frequency electrical energy of predetermined energy content from a generator having an oscillatory circuit embodying a valve arranged to oscillate for a predetermined limited period of time after the commencement of oscillation, and successive pulses are initiated at a repetition frequency dependent on the speed of the work relative to the electrodes. The amount of heat supplied to a seam is thus dependent only on its length, and is independent of variations in the speed of feed. A commutator driven by the roller electrodes, feed rollers or equivalent means at a speed proportional to the rate of feed of the material acts as a switch to initiate the pulses of energy (see Group XXXV). Means are provided for adjusting the pulse duration according to the requirements of the welding operation.
