Patent EP-0056770-A2 (EP)
Inventor: PALMERSHEIM GERARD M
IPC: F15B20/00
Filed: 1982-01-18
Abstract: A hydraulic system (40) for an excavator (10) which utilizes regeneration, minimizes cavitation, and provides hose break protection is disclosed. A valve assembly (50) is permanently connected to a hydraulic actuator (30) which is to be controlled. A hydraulic power supply (42) remote from the hydraulic actuator is connected to the valve assembly (50) through a pair of flexible hoses (56, 58). Pressurized hydraulic fluid can flow to the valve assembly through either of the flexible hydraulic hoses, but the valve assembly (50) includes a check valve (60) so hydraulic fluid return is only possible through one hose (56). A two position valve (62) is provided in the valve assembly (50) between a pair of operating ports (36, 38) on the hydraulic actuator (30). The two position valve (62) can be opened in response to a signal from the operator, connecting the two ports (36, 38) together to permit regeneration. The valve assembly (50) also includes a pressure relief valve (64) connected to one of the ports (38) to limit overpressure. A second check valve (66) is connected around the pressure relief valve (64) to permit hydraulic fluid to flow from a reservoir (43) to the hydraulic actuator (30). The reservoir (43) is pressurized at a relatively low pressure, so when the pressure at the associated port (38) drops below the reservoir pressure hydraulic fluid flows through the second check valve (66) to the port (38) and minimizes cavitation.

Abstract: A diphenylamine compound that is a precursor for a phenazine dye comprises, in an ortho position to the amine of the diphenylamine, a sulfonyldiamido group (-NHS0 2 -NH-) that is capable of releasing a sulfonylamine fragment upon oxidation. The diphenylamine compound upon oxidation intramolecularly cyclizes to a phenazine dye. The sulfonylamine fragment is capable of thermally releasing ammonia or an amine. The diphenylamine compound and sulfonylamine fragment are useful in imaging materials such as photothermographic materials. Ammonia or an amine thermally released from the sulfonylamine fragment enables imaging in imaging materials that are responsive to ammonia or an amine. The diphenylamine compound also is a silver halide developing agent.

IPC: F01K25/06
Filed: 1984-08-10
Abstract: An absorption type heat transfer and thermally powered temperature pressure potential amplifier system for storing energy by distilling and separating solute from a solution of the solute and a solvent at a low temperature, then amplifying and recovering the temperature and/or vapor pressure potential difference between the solute and the solution at a higher temperature in the form of heat transfer or its mechanical power equivalent. One working fluid is a solute having a low boiling point, the other a solution of the solute in a solvent having a high boiling point such that mutual solubility is poor at low temperatures as indicated by a small vapor pressure difference between solute and solution, and in which the vapor pressure difference between solute and solution greatly increases at higher temperatures. This permits the vapor pressure potential difference to be released in the form of mechanical work when vapor from separated solute is reabsorbed into solution in an absorber at the higher temperature. Similarly, an amplified temperature difference exists between liquid solute and absorbent solution in a high temperature absorber when solute vapor passes freely into solution within the absorber. The working fluids are circulated in a closed cycle with an intermediate counter-flow heat exchange means for exchanging heat between separated solute and solution moving from the colder distilling means, and recombined warm solution returning to the colder distilling and separating means from the higher temperature absorber. This system utilizes low grade heat from natural sources.

Abstract: A method of calibrating a scanning carriage drop-on-demand ink jet ejector (1) wherein the ejector is traversed past a droplet detection light beam while droplets are ejected. By knowing the position of the ejector and relating it to the amount of light blocked by droplets, horizontal errors in drop position can be detected. Similarly, by measuring the amount of time elapsing between droplet ejection and droplet detection, the velocity of the droplets can be determined. Corrections can be made by adjusting the time of ejection and/orthe drive pulse amplitude and/or width.

In one embodiment a floating additive injection pump piston has a stack of displacement control washers engaged therewith and disposed on the piston rod. In another embodiment the pump piston passes through a seal member between a pump chamber and a bypass chamber and an elongated spiral groove formed on the periphery of the pump piston determines the effective displacement of the pump. A spring biased toggle type linkage snaps the motor valves into open and closed positions to provide positive movement of the valve members. Liquid additive is injected into the primary fluid stream at the outlet passage of the apparatus and downstream of the motor mechanism.

Abstract: An improved method and apparatus are provided for making vibration sensors, particularly of the type used in automotive applications wherein a piezoelectric element is affixed to a flexing plate which is mounted on a support stem in "umbrella" fashion. A desired resonant vibrating frequency of the sensor is obtained by progressively working a neck portion of the support stem, as by peening, to effectively decrease the vibrating radius of the plate and thus increase its resonant frequency toward and to a desired resonant frequency. The plate's frequency is monitored and the working of the stem neck portion is terminated when a desired resonant frequency is attained. An inclined support shoulder on the stem below the neck portion facilitates the aforementioned manufacture. An undercut positioned in the stem neck portion near its transition into the support shoulder further facilitates the manufacture.

Abstract: An acceleration nozzle for particles entrained in a carrier gas comprises a first central nozzle having a first diverging cross-section, and an extension nozzle section extending from the first nozzle. The extension nozzle section has a flare or diverging angle which is greater than that of the first acceleration nozzle. The nozzle extension is surrounded about its mouth or opening by a second nozzle forming a casing or housing therearound; the second nozzle being connected to a source of gas. In a preferred embodiment, instead of utilizing two distinct gas sources to supply the first acceleration nozzle and the second "housing" nozzle, a portion of the gas passing through the acceleration nozzle may be diverted by means of slits built into the latter. The slits act as a separator of the gaseous phases and solid particles, and prevent the solid particles from penetrating the second nozzle. Acceleration nozzles of the present invention are typically used for delivering carboniferous powdered materials into a steel bath.
