Abstract: A diet cap device for visually indicating rotation of a fastener and for keeping the fastener clean. The device includes a base and a receptacle. The base has a central portion that is circular-shape and has a circumference and a extended diameter that extends past the circumference and an extended diameter that extends past the circumference thereof. The receptacle is disposed on the base and receives the fastener and includes a collar that is concentrically disposed on the central portion of the base and spaces the base away from direct contact with a wheel and a cap that is concentrically disposed on the central portion of the vase, opposes, and is coaxial with, the collar and cover and protects the fastener from dirt.

Abstract: A conventional magnetomechanical EAS marker is modified to aid in authenticating an article of merchandise to which the marker is to be applied. The marker includes a housing, a magnetostrictive element in the housing, a bias magnet mounted to the housing, and an authentication element in the housing for indicating the authenticity of the item to which the marker is to be applied. The authentication element may be a printed logo, bar code or character string or a discrete element having distinctive or rare characteristics.

Abstract: The casing of a multi-function key holder has a front casing portion which includes parallel top and bottom parts that extend forwardly and that are spaced apart vertically to define a lens receiving space therebetween, and a rear casing portion which extends rearwardly from the front casing portion and which confines an air chamber. The rear casing portion is formed with an air inlet adapted to permit blowing of air into the air chamber, and an air outlet adapted to permit releasing of the air that was blown into the air chamber, thereby permitting generation of a whistling sound output. A planar magnifying lens piece is disposed in the lens receiving space, and has an edge section mounted pivotally on the front casing portion. The lens piece is movable between a concealed position, where the lens piece is confined between the top and bottom parts of the front casing portion, and an extended position, where the lens piece is exposed from the top and bottom parts of the front casing portion.

Abstract: A fluid sensor for heat exchanger system includes a supporting device such as a tubular hose fitting for mounting the sensor in the system so that heat exchanging fluid circulated in the system comes into contact with the sensor. A window or sight glass is mounted in the supporting device along with corrodible separating means interposed between the sight glass and the heat exchanging fluid. A visual indicator such as a movable flap or a colored ball can be viewed through the sight glass when the separating means is ruptured or broken by corrosion. The viewing of the indicator provides an indication that the heat exchanging fluid has reached a certain corrosive state and requires replacement or treatment. In a preferred embodiment, the separating means is a metal diaphragm spaced from the sight glass.

Abstract: An attache case with a storage compartment for an umbrella and signalling means for the user to signify when an umbrella is, or is not, in place in the compartment so that inadvertent forgetfulness will not thwart use of the case as intended.

Abstract: A device for use in pulling ropes is in the form of an elongated handle having a passage extending between one end and the side thereof. A cleat located in the passage is adapted to grip a rope in the passage and to support a tensional force in a rope emerging from the passage at the side of the handle.

Abstract: A portable pocket-size card holding device includes a holder capable of holding a plurality of cards. The holder comprises a pair of spaced floor and top members, laterally spaced side members extending between the floor and top members, and an end member extending between a first set of ends of the floor, top and side members so that the one end of the holder is closed off and its other end is open, with the members defining between them a cavity. Spaced channels are provided along the top and floor members. The channels are located inside the cavity and extend substantially parallel to one another, with the channels of the top member being aligned with those of the bottom members so that, in use, cards in the holder will extend substantially parallel to the side members. Each pair of channels in the top and floor members provides a card receiving zone capable of accommodating a single card.

Abstract: A hanger for womens purses, handbags, shopping bags, or other articles, is provided which consists of a pair of elongated hinged support arms with a rubber semi-cylindrical bail mounted at the distal end of one of the arms, and with some means at the distal end of the other arm from which a purse, or other article may be suspended. The hanger is constructed to extend over the edge of a flat or curved surface, such as a table, chair arm, or the like, with the rubber bail engaging the surface in a non-slip relationship and with the article being suspended by the hanger over the edge of the table top, arm, or the like. The hanger is foldable to a compact configuration when not in use, and when so folded, it is constructed so that it may be used as a police whistle to summon help in cases of emergency.

Abstract: A tightening wrench with an angle indicator for the final tightening operation on threaded fasteners, the angle indicator having a pointer or other angle indicating element which assumes a given angular orientation under the influence of an ambient force field of gravity or magnetism and maintains this orientation while the wrench is rotated, thereby giving an angular reading of the tightening angle. Gravity is used with a weighted pointer, magnetism with a needle compass or liquid compass. Also usable is a gyro, or a freely rotatable mass of high inertia. The wrench may be a torque wrench.
