Abstract: A fluid spraying system includes a displacement pump configured to mount to a drive housing. A reciprocating drive is connectable to a pump rod of the displacement pump and includes a connecting rod and a drive link that receives a head of the pump rod. A tightening ring that includes threading is configured to rotate about a cylinder of the pump and shift axially along the cylinder and engage with a bottom side of the drive housing to secure the displacement pump to the drive housing.

Abstract: A displacement pump is configured to mount to a drive housing. A reciprocating drive is connectable to a pump rod of the displacement pump and includes a connecting rod and a drive link that receives a head of the pump rod. A flange projects from a pump body of the pump and a ring projects from the pump body of the pump. A portion of the drive housing is received in a gap between the flange and the ring.

Abstract: A method and apparatus for forming raised ridges on the surface of a turbine component having an abradable coating formed on an outer surface thereof which includes a mask having a predetermined pattern of openings therein adjacent the abradable coating on a surface of the turbine component; and a high pressure water jet that has movement relative to the mask so that the high pressure water jet passes along the extent of the openings in the mask and passes through the openings in the mask to remove portions of the abradable coating on the turbine component located beneath the openings in the mask.

Abstract: A method and apparatus for removing a coating having an irregular surface configuration that includes mapping the irregular surface configuration, and using the mapping determination in controlling the operation of an abrasive water jet to provide increased material removal rates at the higher points in the irregular surface and decreased material removal rates at the lower points, and thereby even out the surface configuration of the coating. The method and apparatus also includes using a detection device for detecting the presence or absence of an element that is unique to a layer of a coating, and using the detection determination in controlling the operation of the abrasive water jet to stop material removal of the coating when the detection device determines there is an absence of the unique element.

Abstract: The present invention provides functional fluid compositions containing a major portion of oil of lubricating viscosity and a novel and synergistic combination of an acylated nitrogen-containing compound having an oil soluble olefinic substituent averaging in carbon number from 8 to 20 and at least one ashless detergent/dispersant.

Abstract: The invention relates to a two-cycle oil additive, compositions and concentrates containing said two-cycle oil additive and methods of preparing and using the two-cycle oil additive which comprises the reaction product of (A) at least one high molecular weight acylating agent (B) at least one polyalkylenpolyamine and (C) at least one monocarboxylic second acylating agent, wherein the molar ratio of the carboxylic acid acylating agent to the high molecular weight acylating agent is at least 3:1 and wherein the tertiary amine to total amine ratio of the reaction product is at least 0.7:1. The two-cycle oil additive of the invention are dispersant additives which will improve engine cleanliness and which will substantially avoid the formation of insoluble gel agglomerants at low temperatures which can adversely affect engine performance.

Abstract: An improved camera for recording stimuli received by the pilot of an aircraft. The camera features an improved mount for alignment of a charge-coupled device image forming element with respect to the housing of the camera. The improved mount comprises inner and outer eccentric adjustment members fitting within a bore in the camera housing. Each adjustment member comprises a cylindrical outer surface and a cylindrical bore, the axes of the cylindrical bores and cylindrical outer surfaces being parallel to but not coincident with one another, such that axial misalignment of an image forming element mounted on the inner adjustment member may be corrected by relative rotation of the adjustment members. Skew adjustment may also be provided. During assembly, the camera according to the invention is mounted on an alignment fixture bearing a predetermined relation to a target.

Abstract: A circuit which is used with a portable or mobile telephone system. The circuit is arranged to be installed between the telephone control unit and the radio transceiver used in mobile telephone systems. The circuit permits "normal" telephone usage with the telephone handset, as well as "hands-free" or speaker-phone operation. Also, duplex (i.e. bidirectional) operation is achieved by reducing, but not eliminating, two-way signal transmission through the circuit.

Abstract: An electrolytic cell is provided for a process which combines at compatible cell geometries and current densities, the electrowinning of a metallic element from an electrolyte with an anodic, electrochemical reaction using a cationic permselective membrane between half-cells to keep the reactions separate. The cell is operated by introducing a metal salt into a catholytic compartment, introducing a compatible electrochemical solution into an anolytic compartment, wherein both of said salt and said electrochemical solution are in an electrolysis cell having a cathode electrode and an anode electrode, and applying an electromotive force across said electrodes whereby an oxidation electrochemical reaction occurs at the anode while the metal of said metal salt is deposited at said cathode.
