Abstract: A pressure sensor probe has a first port connectable to a relatively low pressure source in a compressor crankcase and a second port connectable to a relatively high pressure source at the output of an oil pump. A shuttle is slidably disposed in a bore and has a first end which closes the first port when the difference in pressure between the two ports indicative of normal operation exceeds a selected value determined by the relative areas of the shuttle exposed to the respective pressures and by a coil spring which biases the shuttle away from the first port. A passage is formed between the shuttle and the bore leading from the second port to a force receiving surface on the high pressure side of the shuttle. The length and cross sectional area of the passage is selected to provide a desired dampening or time delay between the high pressure source and the force receiving surface. Indicator means responsive to the position of the shuttle is used to indicate the status of the oil differential between the two ports and, if desired, to control the actuation of the compressor motor.

Abstract: In a two-bed pressure swing adsorption system for separating a multicomponent gas mixture step in which the two beds communicate with one another, the bed which is to undergo regeneration is equalized with at least one tank 15, which is at a lower pressure, in order to transfer part of the gas located in the bed void volumn. After the bed is regenerated, it is again equalized with the same tank 15, now at a higher pressure than the bed, in order to return the conserved gas. This process increases yield by decreasing the loss of gas attributable to bed void volume. The present process has been applied to increase the yield of argon which is separated from a mixture consisting of hydrogen, argon, nitrogen and methane.

Abstract: In an earth boring bit of the type having a rotatable cone (15) secured to a bearing shaft (26), an improved pressure com­pensating and relief system (27). A flexible diaphragm (57) has an enlarge peripheral portion (63) in an o-ring configuration sea­lingly secured in a compensator cavity to form a mud region and a lubricant region. A central portion (59) of the diaphragm has a perforated and ridged protrusion extending into the mud region to form a self energizing area, exposed to the mud region, that seals the perforation when the pressure of the lubricant is less than or substantially equal that of the mud. A wall (43) at the end of the compensator cavity sur­rounds the mud passage and engages an area around the pro­trusion when the diaphragm is fully extended by lubricant pressure build-up that exceeds the hydrostatic pressure. Thus, the resulting pressure differential opens the perfo­ration (61), releases lubricant and relieves the build-up of lubricant pressure. However, the configuration of the pro­trusion is such as to prevent the entrance of mud into the lubricant reservoir since the exterior area of the pro­trusion exceeds that of the interior area. The differential pressure to open the perforation is selected to be not less than about fifty psi and the preferred form of the protru­sion is substantially cylindrical, its perforation and lubricant entrance being beveled. An absence of metal bonded to the diaphragm helps avoid failures due to stress induce separations and debonding due to chemical attack. Clearances (D₁, D₂) are used between the diaphragm and the end of the cavity and the end of the protector cup to provide self centering with the lubricant and drilling mud passages.

Abstract: A powder measuring device and powder measuring mixer in which powder is supplied from a supply hopper to a measuring hopper with its flow rate controlled by a flow regulator associated with the hopper. The weight of the measuring hopper is monitored. A controller compares the measured weight with a target rate to produce a deviation therebetween and a time variation of the deviation. The controller operates according to fuzzy inference to produce a desired flow rate for the next control cycle. This desired flow rate is then supplied to the flow regulator. Several supply hoppers with associated flow regulators can be used. Then the output of the controller is switched between the different flow regulators at different phases of the mixing measurement. Additionally, the measuring hopper can be movable between the different supply hoppers so as to avoid complicated piping.

Abstract: A data input device having key switches (4) which are temporarily in an operated position, and position-hold switches (8) each having selectable stable positions. The device includes a first matrix, a second matrix, and a matrix scanning arrangement (10, 20, 22). The first matrix comprises first and second signal lines (IN1-IN8, OUT1-OUT10), and the second matrix comprises third and fourth signal lines (IN1, IN2, OUT11-13). Each key switch is connected between the first and second lines at a corresponding one of intersections which are formed on the assumption that the first and second lines cross each other. Similarly, each position-hold switch is connected between the third and fourth lines at a corresponding one of intersections thereof. Some (IN1, IN2) of the first or second lines are used as the third or fourth lines. The matrix scanning arrangement scans the first matrix to determine whether each key switch has been operated, and scans the second matrix to determine selected one of the stable positions of each position-hold switch, only when a scanning of the first matrix indicates that the number of the key switches which have been operated is not greater than a reference value.
