摘要:
An irrigation sprinkler includes a head having a first water outlet passage that communicates with a nozzle receiving socket. A nozzle is slidably mounted in the nozzle receiving socket. The nozzle includes a hollow support body defining a second water outlet passage that communicates with the first water outlet passage. The nozzle also includes a portion obstructing the second water passage and defining a nozzle orifice. The nozzle also includes a cantilevered pry flange that extends in a lateral direction from an outer end of the support body. The pry flange has a portion that terminates short of a wall of the nozzle receiving socket to create a gap sized for ready insertion of a tool to facilitate removal of the nozzle from the nozzle receiving socket. The sprinkler includes conventional structure for supplying the first water outlet passage of the head with pressurized water.

A gas diffusion arrangement (22) for a gas turbine engine (10) is disclosed. The gas diffusion arrangement (22) has an inlet (26) and an outlet (28) for the gas, and comprises diffusion means (32) having an upstream region (38) and a downstream region (40). Distribution means (41) is arranged between the downstream region (40) and the outlet (28) to distribute the gas into a desired flow pattern. The area ratio of the cross-sectional area of the downstream region (40) to the cross-sectional area of the upstream region (38) is greater than 1.5 to 1.
摘要:
A hand-held shower attachment having a handgrip arranged on one side of its showerhead, where the ratio of the length of the grip to the maximum lateral dimension of the showerhead is less than unity, which will allow configuring a water-conserving shower attachment having a good rinsing action, is disclosed.
摘要:
A surgical instrument comprises a probe (3) including an elongate hollow outer member (14) having a cutting window (16) at its distal end portion. An elongate drive shaft (15) is disposed within the outer member (14) and is mounted for rotation about its longitudinal axis within the probe. A cutting tool (17) is located at the distal end of the drive shaft, and is positioned adjacent to the cutting window (16). An indicia in the form of an etched marking (18) runs proximally along the outer member (14) in alignment with the center of the cutting window (16). The indicia allows the user of the instrument to ascertain the position of the cutting window (16), whatever the orientation of the probe (3).
摘要:
A high velocity cutting nozzle for connection to the fluid supply tube of a high pressure fluid cutting system. The nozzle includes a housing which threadably connects to the fluid supply tube for receiving pressurized liquid therefrom. A bushing disposed within the housing sandwiches a removable sleeved jeweled orifice disk therebetween at a spray outlet bore of the housing. The bushing includes a flow directing bore with a convergent inlet portion for reducing turbulence, and an outlet portion having an annular cylindrical or divergent inner surface, and an annular convergent angled or curved end surface. The sleeved orifice disk is in co-axial fluid communication with the flow-directing bore and a spray outlet bore of the housing to facilitate fluid flow. The sleeved orifice disk fits within a sleeve receiving bore in the bushing immediately downstream of the flow-directing bore abutting a shoulder of the bushing.

The present invention is directed to a method of manufacturing a high density analysis device, preferably a microarray, comprising attaching an activatable material to a substrate, such that the activatable material and the substrate are in direct contact, to form a surface material; ii) immobilizing a porous or non-porous material onto the surface material; and iii) binding the immobilized porous or non-porous material with a probe to provide the high-density analysis device, and articles of same.
摘要:
The present invention provides a spray gun with associated nozzle attachments for high deposition efficiency for thermal spray of high quality, dense, low oxide content coatings. The spray guns are used to produce coatings using a thermal spray process, a high velocity oxy-fuel process, a high velocity air-fuel process, cold spraying, and plasma spraying in which the process is characterised by having an over-expanded flow with a Mach number from about 1.0 to about 4.0 which have passageway section which diverges to the gun outlet. In one embodiment the nozzle attachment is another diverging section with a greater angle of divergence than the diverging nozzle section. In another embodiment the nozzle attachment includes the aforementioned diverging nozzle attachment section followed by a converging nozzle section having an outlet section through which the thermal spray is emitted.

A nozzle insert that is capable of being irreversibly attached to a needle valve tube such that the resulting needle valve member can be used in a nested needle valve configuration for a dual mode fuel injector.
摘要:
A metal plating bath containing alcohol compounds that inhibit or retard the consumption of plating bath additives. The additives are chemical compounds that improve the brightness of the plated metal, the physical properties of the plated metal especially with respect to ductility and the micro-throwing power as well as the macro-throwing power of the plating bath. The alcohol compounds that inhibit or retard the consumption of additives increases the life of the plating bath and improves the efficiency of the plating process. The plating baths containing the alcohol compounds that inhibit or retard additive consumption can be employed to plate copper, gold, silver, palladium, platinum, cobalt, cadmium, chromium, bismuth, indium, rhodium, ruthenium, and iridium.
摘要:
A container for a substance to be applied is provided that includes a housing, an application tip, and a closure cap. The application tip and the closure cap are alternatively removably securable to the outlet end of the housing in a substantially fluid tight disposition. A first indicia is associated with the housing and a second indicia is associated with each of the application tip and the closure cap. The second indicia has an identity correspondence with the first indicia such that the presence of both the first indicia on the housing and the second indicia on the respective one of the application tip and the closure cap secured to the outlet end of the housing confirms that only the appropriate application tip or the appropriate closure cap has been secured to the housing.
