Abstract: A garment hanger having an indicia-bearing tab for displaying customer information is provided. A tab holder is integrally formed as part of the hanger. The tab is mounted on an edge of the tab holder, adjacent a ridge formed on the tab holder. The ridge, together with two end members formed on the tab holder on either side of the tab, prevent a consumer from obtaining a finger purchase on the tab. Thus, once the tab is mounted on the tab holder, it cannot be removed without using a tool. The dimensions of the ridge and end members, and their location on the tab holder, may be selected to prevent removal of the tab by hand or by tool.

Abstract: A tilt switch comprises a housing forming a cylindrical inner chamber and having two electric terminals extending through an end wall of the chamber. A mercury mass of less volume than the chamber is disposed within the chamber and is arranged to electrically interconnect the terminals when the switch is in a first position relative to vertical, and to break the electrical contact when the switch is tilted to a second position relative to vertical. A spherical body of less density than the liquid and including a non-electrically conductive outer surface floats upon a surface of the liquid and is pushed upwardly against a surface of the chamber. The spherical body has a smaller diameter than the diameter of the chamber to define a restriction passage which inhibits the flow of liquid when the switch is subjected to shock.

Abstract: A foldable garment hanger capable of being attached to and folded with a garment and then boxed, if necessary, and shipped with the garment in a minimum of space so that the hanger needs merely to be unfolded with the garment and hung upon arrival at the retail store. The hanger is comprised of a hanger body, a suspension member and two arms, each with garment retaining means at its end. The arms are connected by a living hinge that enables the arms to be folded toward each other. The suspension member possesses latching means and is connected to the body by a hinge that enables the suspension member to be folded along the hinge and latched to the body arms for support in hanging of the hanger.

Abstract: A shock sensor has a mercury wetted insert for supporting a mercury mass normally spaced from a terminal or terminals. The mercury and the terminal or terminals are contained within a sealed housing. When the sensor is subjected to a shock, the mercury is redistributed and protrudes from the insert so as to make contact the terminal or terminals and complete a circuit. By providing a mercury-non-wettable surface ahead of the mercury wetted insert, a closure delay time or operation time is selectively set. Additionally, the porosity of various membranes within the housing can be pre-selected to vary the speed in which the mercury is redistributed and thus also adjust the closure delay time. Also, a constriction in the non-wettable surface ahead of the mercury wetted insert can be utilized to provide a time delay by introducing a dash-pot effect.

Abstract: The invention concerns an endoscopic instrument having a three-dimensional optical viewing system. Images from an interior body region are transmitted through image transmission elements contained within the endoscope probe to a prism arrangement. The prism maintains the images in upright position regardless of the rotation of the instrument. A shutter system operating at a predetermined frequency alternately opens and closes the optical path of each image. These images are converted to electrical pulses in accordance with the requirements of the three-dimensional television system used to display an image of the body region.

Abstract: An electric resistance welder comprises a frame and a movable arm mounted to the frame for gravitational movement relative thereto. A movable electrode is carried at an end of the movable arm. A stationary electrode is spaced opposite the movable electrode to accommodate a plurality of workpieces therebetween, with the movable electrode resting against the workpieces and gravitationally biased toward the stationary electrode. An electric pulse is conducted through the electrodes and workpieces for heating and softening the workpieces to enable the arm to accelerate toward the stationary electrode at the acceleration of gravity, whereby the movable electrode collapses the workpieces toward one another. A stop is arranged to be engaged by the arm for terminating travel of the arm when the movable electrode has traveled a predetermined distance toward the stationary electrode, and subsequent to termination of the electric pulse.

Abstract: An improved automatic welder's helmet having two pneumatic cylinders to effect the closing of the helmet's dark eye lens prior to energizing the welding system for striking the welding arc, and further to maintain the dark eye lens closed until after the arc and the weldment's white afterglow have ceased. Additionally, the invention includes a ventilation system manually controlled to ventilate the helmet and to remove welding fumes and smoke from the interior of the helmet and the dark eye lens.

Abstract: A decorative oil lamp comprises an enclosure formed by a pair of oppositely dished plates, the lower plate being reflective and the upper plate being transparent. An opening is present in the upper plate in which is supported a wick assembly consisting of a vertical tube and a wick therein whose lower end is immersed in oil present in the enclosure. When the upper end of the wick is lit, the reflective lower plate projects light from the flame upward and reflects the wick assembly so that it appears to be burning at both ends.

Abstract: A shock sensor has a mercury-wetted insert for supporting a mercury mass normally space from a terminal. The mercury and terminal are contained within a sealed housing. When the sensor is subjected to a shock, the mercury is redistributed and protrudes from the insert so as to contact the terminal and complete a circuit between that terminal and another terminal that is normally in communication with the mercury.

Abstract: A light-weight portable winch which incorporates a low-horsepower motor, a speed-reducing transmission which is supported by outrigger bearings, a cable take-up drum which is disengagable from the speed-reducing transmission, and a positive lock brake which acts on the drum and which is operable, independently of the winch motor, to prevent rotation of the drum.

Abstract: A ball sealer consists of an inner spherical rigid core of a desired density and an outer resilient or compliant continuous layer of uniform thickness which is comprised of a pair of hemispheric caps positioned about and secured to the core and to each other.The ball sealer is formed by molding a first cap in the form of a hemisphere having a central cavity adapted to receive one-half of an inner core. The cap is placed in a cavity in the bottom plate of a mold and the outer surface of an inner core or the inside of the cavity of the cap is coated with an adhesive that will bind the cap to the core. The core is then placed within the cavity of the cap. A cavity plate having a hemispheric cavity is then positioned on top of the bottom plate of the mold with exposed upper half of the inner core received within the cavity of the cavity plate.

Abstract: A decorative lamp comprises a chimney and an illumination source in the form of a candle or oil lamp. The oil lamp or candle is supported by an integral hanger that rests against the side of the chimney and provides an appropriate standoff to center the illumination source within the chimney. The hanger also has a hook that engages the top of the chimney and a leg that properly orients the illumination source vertically within the chimney.
