An operator for a window comprising a base and a cover, the base being attached to a window sash with an aperture extending through the base, an arm having first and second ends with a first end secured to the base, the first end of the arm having an aperture therein overlying the aperture in the base and an upper securement member extending at least partially through the aperture in the first end of the arm, the upper securement member having a threaded recess therein, a lower securement member screwthreadedly engaged with the upper securement member and extending through the base in an abutting relationship thereto, the cover engaging with the upper securement member to prevent rotation thereof when the lower securement member is screwthreadedly engaged with the upper securement member.

Window operator

An operator for a window comprising a base designed to be secured to a window sash, an arm having first and second ends with the first end being secured to the base and a first end of the arm having a worm wheel formed thereon, a shaft having a worm operatively connected to the worm wheel, a handle secured to the shaft, a locking mechanism comprising a multipoint tie bar, and an actuator connected to a rack and pinion gear arrangement to move the multipoint tie bar between open and locked positions. The arrangement provides for a compact efficient design which includes a locking mechanism and an opening mechanism located at the same point.

An operator for a casement window, the operator comprising a base, at least one arm for securement to the base, an upper securement member extending through an aperture in the base and an end of the arm with the securement member having a threaded recess therein. A lower screw securement member is screw threadedly engaged with the upper one to assist in drawing the arm into the desired position. A monocoque housing surrounds the operator and has sealing members to prevent air infiltration.

Casement window operator

An adaptor for a window locking mechanism wherein the locking mechanism includes a keeper on a window sash and a cam roller on a window frame, the adaptor comprising a body portion having first and second sides with a recess being formed in the body portion, the recess being sized to receive a portion of the cam roller, the body portion further having at least one ramped portion extending from an edge of the recess to the first side. The adaptor can be used with conventional cam roller windows and provides an improved surface engagement and a greater displacement span.

The invention disclosed is a novel bulkhead structure for use with rocket launchers which employ a plurality of cylindrical launch tubes. The bulkhead includes openings which are aligned with corresponding launch tube openings. The bulkhead openings are counterbored to receive the launch tube ends and to provide a smooth transition between the launch tubes and the bulkhead to prevent rocket-to-bulkhead interference when the rockets are launched.

A low cost easily installed and reliable weather seal for the nozzle throat of a solid propellant rocket motor which uses an aft end ignition system. The igniter cartridge, known per se, which is located in the throat of the rocket motor is provided with an elastomeric O-ring in the base of the cartridge thus sealing the gap between it and the inside surface of the exit cone of the nozzle. This structure not only provides an effective weatherseal but also provides a convenient means of positively retaining the igniter cartridge in place.
