Abstract:
Nozzle assemblies are provided which are effective for atomizing and mixing different or unlike fluids, and for combining the mixtures with solids and the like. The nozzle assemblies project the fluids, in the form of sprays or jets, which combine or mix at points or areas spaced forwardly of the nozzles, whereby clogging of the nozzles is avoided, and the separate fluids are prevented from contaminating each other within the nozzles or other parts of the assemblies. Nozzles of special or unique design are provided, which have an improved atomizing action.

Abstract:
A safety apparatus for striker-fired weapons, mountable at the back end of the weapon's slide and comprising a spring loaded button associated with a ram bar, wherein, when the spring loaded button is actuated by a user, the ram bar temporarily displaces a component of the weapon's firing mechanism, such that, although the weapon's trigger can still move full range, discharge of the weapon is prevented and the weapon is thus temporarily in safe mode; and wherein, as soon as the user releases the spring loaded button, the spring loaded button returns to its position before actuation by the user, causing the ram bar to stop the temporary displacement of the component of the weapon's firing mechanism, the weapon being thus returned to its normal, ready-to-fire mode.
Abstract:
A bearing assembly includes a first bearing comprising a first inner ring and a second bearing comprising a second inner ring. A sleeve-shaped spacer is disposed between and axially separates the first and second inner rings. An adhesive connects the spacer to the first and second inner rings.
Abstract:
A hydraulically actuated pump of the piston-diaphragm type for pumping a liquid such as paint through an airless spray gun having a flexible hose which is connected to the pump outlet downstream of the outlet check valve and which has a volumetric capacity many times the displacement of the diaphragm actuating piston to constitute an elastically expansible and contractible pressure storage vessel. The driving fluid chamber of the pump between the piston and diaphragm has a restricted adjustable pressure control valve to control the operating pressure of the pump and an automatic hydraulic inlet-outlet valve operative upon arrest of the return movement of the diaphragm, to admit driving fluid from a reservoir into the driving fluid chamber during the continued terminal portion of return stroke of the piston and to permit expulsion of driving fluid from the driving fluid chamber to the reservoir during the initial portion of the pressure stroke of the piston to adjust the volume of hydraulic fluid between the piston and diaphragm thus to maintain a predetermined rate of discharge of the pumped liquid through the spray gun during the pressure and return strokes of the diaphragm and piston. During the return stroke of the diaphragm and piston, the outlet check valve closes so that continued return movement of the piston draws the diaphragm with it to the stop position to draw in through an inlet check valve liquid to be pumped during the next pressure stroke of the piston and diaphragm.In standby operation of the pump with continued reciprocation of the piston, the pressure control valve opens to decrease the volume of driving fluid to correspond to the net displacement of the diaphragm for continued back and forth flow of pumped liquid into and from the pressure storage vessel, the outlet check valve being of light weight material having a specific gravity only slightly greater than that of the liquid being pumped and having a relatively large opening movement so that it does not engage its seat during the back and forth movements of the piston and diaphragm during standby operation.
Abstract:
A direction finder including downstream the reticle an intermediate objective and a four quadrant detector, the reticle providing a modulation at a given frequency and in which the intermediate objective comprises preferably a half-ball lens whose center of curvature coincides substantially with the detector center to allow a relative movement of the reticle with respect to the detector, such as a rotation round this center controlled by a driving device.
Abstract:
A nozzle assembly includes a stem and a cap. The stem includes two passages for carrying the same liquid or different liquids under high pressure. The passages terminate at a conical end surface of the stem. The cap is seated on the end surface of the stem and cooperates with the end surface of the stem to define two nozzle openings or orifices. The cap is arranged so that rotation of the cap on the stem changes the size of the orifices.
