Jet pump in a boiling water-type nuclear reactor

Abstract: An improved jet pump for a nuclear reactor is disclosed A combination of novel nozzle, mixer and diffuser configurations give a jet pump of uniquely high efficiency This jet pump is especially useful in circulating cooling water through a boiling water-type nuclear reactor

Close-up camera attachment

Abstract: A camera attachment for close-up use comprising a vertical supplementary lens-holding plate having a downwardly angled light deflecting panel at the upper portion thereof and optionally an upwardly angled light-deflecting panel at its lower portion, a locator arm attached to and extending out from said plate for a fixed and predetermined distance, a view-bracketing frame at the terminus of said arm, an optional translucent light diffuser window in the lens-holding plate opposite the light source and on the vertical side of a hood arrangement formed by the angle between the vertical lens-holding plate and the downwardly angled light-deflecting panel.

Air conditioning terminal

Abstract: A variable volume ceiling air-conditioning terminal having a diffuser construction to discharge air along the surface of the ceiling for attachment of the air stream thereon to evenly distribute the air within the area being conditioned.

Diffuser mounting arrangement for lighting fixtures

Abstract: A mounting arrangement for the diffuser of a recessed lighting fixture which enables the diffuser to be selectively securely retained in a normal position closing the open end of a light housing, and an actuated position outwardly spaced from the open end of the housing wherein access to the housing interior for servicing, or the like is facilitated. The arrangement is such as to continuously support the diffuser during movement between the normal and actuated positions and to positively lock the diffuser in the actuated as well as the normal position. Inadvertent return of the diffuser from actuated to normal position is thereby prevented.

Auxiliary cold-starting carburetors for internal combustion engines and feeder tanks thereof

Abstract: This auxiliary carburetor comprises a reservoir which is recharged with liquid, in ordinary, nonatomized liquid form, from a recharge tank through check valves. The liquid is expelled, under air pressure, through a dipping tube and a diffuser which atomizes this liquid.

Air diffuser construction

Abstract: 1,130,342 Ventilators AIR DEVICES Inc 16 Nov, 1965, No 48725/65 Heading F4V [Also in Division B3] Strip-like elements of the form shown are located on the divergent portions of a rectangular nested skirt air diffuser, Figs 1-3 (not shown), and provide a series of air directing vanes B parallel to the axis of the diffuser The element shown is formed by die cutting a blank strip to form the vanes B, bending the vanes to a position at right-angles to the strip, and bending an edge portion D of the strip When located in the diffuser, the portion D lies against the throat of a skirt, the main portion A overlies the divergent portion of the skirt, and the edge 54 of the strip is engaged by an overturned free edge of the skirt
