Title: Motor vehicle hydraulic brake system
IPC: B60T11/20
Filed: 1962-03-12
Abstract: 945,273. Fluid-pressure brakes. KELSEY-HAYES CO. March 12, 1962 [May 5, 1961], No. 9361/62. Heading F2F. An hydraulic brake system comprises a dual master cylinder 11 having a first fluid displacing means 18 to actuate one set of wheel cylinders 85 and a second fluid displacing means 26 to actuate a second set of wheel cylinders 54, decelaration responsive means 93 to reduce the hydraulic pressure on the wheel cylinders 85 and deceleration responsive means 60 to increase the hydraulic pressure on the wheel cylinders 54. As shown, operation of the brake pedal connected to a push-rod 23 causes plunger 18 to move to the left to close a port 20 communicating with the reservoir chamber 15 and forces liquid through passage 97 into chamber 96 through ports 98 and the interior of a cage 90, thence past residual valve 86 to the rear wheel cylinders 85. The body of liquid in chamber 27 transmits movement to the plunger 26, to move it to the left so that liquid is displaced from chamber 43 through a passage 50 into a chamber 49, thence past residual valve 51 to the front wheel cylinders 54. Movement of the plunger 33 integral with the plunger 26 to the left displaces fluid from chamber 41 which is permitted to flow past a seal 40, whose outer lip acts as a check valve into the chamber 43. The pressure built up in chamber 58 which is a result of displacement of liquid from chambers 41 and 43 moves a plunger 64 to compress a spring 65 which in turn holds a valve 77 closed. At a predetermined rate of deceleration a ball 93 will move forwardly up the conical surface 92 of the cage 90 to close the port 91. Further displacement of fluid from the chamber 27 into the chamber 96 moves the cage 90 to the left to increase the pressure in the chamber 82 but due to the pressure in chamber 96 acting on the left-hand side of a plunger 101 attached to the cage 90 which counteracts pressure in chamber 96 acting on the right-hand side of the cage 90 the pressure in chamber 82 is lower than that in the chamber 96. At the same time as the ball 93 closes the port 91 or at a different time during vehicle deceleration depending on the inclination of the bottom of the conical surface 59, a ball 60 engages a seat 61. By this time the plunger 64 will have moved to the left so that the stem 67 does not interfere with the seating of the ball 60 which " freezes " the spring 65 so that no further loading takes place. Upon a further increase in pressure in the chambers 43 and 41, the pressure increase in the latter causes the valve 77 to relieve the additional pressure through passage 71 to the reservoir chamber 16 so that from there on pressure in the chamber 41 remains constant and the pressure in the chamber 43 is increased relative to that in chamber 27 due to the higher pressure in the chamber 43 over that in chamber 41 preventing by-passing of fluid around the seal 40. The volumetric displacement from the chamber 43 will be determined in proportion to the area of the plunger 26 minus the area of the plunger 33.

Title: A water heater or steam generator adapted to be fired by liquid or gaseous fuel
IPC: G05D23/275
Filed: 1923-04-12
Abstract: 219,067. Pattison, C. M. April 12, 1923. Electromagnetic interrupters. - The supply of liquid or gaseous fuel to a water heater or steam generator is controlled automatically in accordance with the temperature of the atmosphere or water or the temperature or pressure of the steam by using a thermostat or pressure gauge to operate an electric relay and set in motion a motor driving a fan which induces a combustible mixture of air and gas in to a combustion chamber where it is fired, the products being then drawn through a flue passing through the water heater &c. The pointer 30 of a thermostat or pressure gauge 27 is adapted to make contact with one or other of the adjustable arms 28, 29 and complete an electric circuit including one or other of the solenoids 31, 32 having cores 49, 50 mounted on a rocker arm 36. Upon a fall of temperature or pressure the solenoid 31 is energized to operate the core 50 and rocker arm so as to cause the fork 59 to dip into mercury pots 60 and complete the main circuit of the motor 25 operating the fan 24. The movement of the rocker arm 36 also causes a ball 52 to pass to the opposite end of the tube 51 and engage with the arm 56 to break the electric contact 54 in the solenoid circuit. The suction side of the fan 24 is connected by a pipe 46 to a chamber 43 containing a liquid and connected to a chamber 44 containing a float 45 adapted to rise and fall with the liquid in the chamber and operate a gas supply valve 62. Suction produced by the fan causes gas to pass from the pipe 63 to a burner 20 where it is ignited by a sparking-plug 21 connected to a magneto 47 driven from the motor 25. The burner 20 vaporizes the liquid fuel in the chamber 17, supplied from the chamber 15 through a pipe, and the vaporized fuel passes into the air conduit 14 and is drawn with air through the gauge 2 to a nozzle 22 where it is ignited by a Sparking-plug 48 and burns in the combustion chamber 3. The combustion products are drawn by the fan 24 through the elliptical flue 5, provided with fins 11, adapted to radiate heat to the water in the boiler 4, and thence through flues 7, 23 to the fan outlet 26. In an alternative arrangement the gas may be supplied direct to the combustion chamber instead of to the burner 20.
