Abstract: A theft prevention device for T-tops. A first latch panel opens and closes over the latch handle of the T-top latch assembly. A conventional lock is used to lock the first panel in the closed position preventing access to the latch handle and, thus, removal of the T-top. The device is supported over the latch housing by ends which cooperate with the latch pins of the T-top.

Abstract: A stretching machine for stretching the legs of an individual which includes a pair of leg bars and a pair of leg decks. Each leg deck is slidingly and pivotingly connected to one of the leg bars to permit adjustments for different leg lengths of individuals. The leg bars are moveable in a general arc from a rest position to stretch positions by a hydraulic jack comprising a jack base, a base jack rod slidingly disposed in the jack base and a connecting rod disposed in the base jack rod. A linkage connects the connecting rod to the leg bars. A channel is slidingly connected to each leg bar and one end of the a pin is connected to the channel, the opposite end of the pin being pivotally disposed in a pivot opening in the leg deck.

Abstract: A respiration monitor for monitoring respiration of an individual comprising a sending light conductor and a receiving light conductor. The sending light conductor and the receiving light conductor are held in a position generally near a portion of the individual which moves in response to the respiration motion of the individual. More particularly, the ends of the sending light conductor and the receiving light conductor are spaced a distance apart and positioned so that the distance between the end of the sending light conductor and the end of the receiving light conductor varies in response to respiration motion of the individual. A light source emits light which is received by the sending light conductor and transmitted therethrough across the distance between the ends of the sending light conductor and the receiving light conductor, such light being received by the receiving light conductor and transmitted therethrough.

Abstract: A pivotally mounted secondary door, such as a screen door, for sliding doors, such as sliding glass "patio" doors. The secondary door swings inwardly and outwardly and preferably is provided with an automatic return. A system of seals is provided for preventing insects and such from entering around the edges of the secondary door and along the sides of the assembly. The assembly can be adjusted to accommodate sliding door frames of different internal vertical dimensions.

Abstract: A weighing unit for use with a scale wherein weight signals are inputted into a weight processor. The weight processor is adapted to output a calculated weight of the non-stationary object which closely approximates the actual or dead weight of the non-stationary object. The weight processor receives the weight signals and identifies weight signals close in time which have differences within a predetermined limit and these weight signals are manipulated to determine the calculated weight.

Abstract: An article and method for shaping a sheet of material around an object such as a flower pot, the article comprising a ring-shaped collar adapted to be secured around the object. The collar may comprise pinch rings or barbed piercing elements, disposed about the periphery of the collar for attaching the sheet of material to the collar, or the collar may be adapted to be secured around at least a portion of the object so that the sheet of material is held between the object and the collar. The article also may be used alone for shaping a sheet of material.

Abstract: An electronic message unit adapted for use with an existing telephone and a public communication link for receiving incoming messages (machine interpretable messages and voice messages) over the communication link and for receiving incoming call signals indicating an incoming message being receivble over the communication link including a telephone control assembly and a message controller. The telephone control assembly is connectable to the communication link and to the existing telephone for receiving call incoming signals and for connecting to the communication link in response to receiving a call incoming signal, the telephone control assembly receiving the incoming messages over the communication link when connected to the communication link and outputting the received incoming messages. The message controller receives the incoming messages outputted by the telephone control assembly and determines the incoming message to be either a machine interpretable message or a voice message.

Abstract: A swing check valve where the opposite end portions of the hinge pin of the disc are held in hinge pin recesses by an annular wall in the valve body. The wall in the valve body is sufficiently sized that the valve disc can swing through the wall through an arc of substantially 90.degree. between in its open and closed positions. The wall may be formed as a part of the valve body or as a separate retainer ring secured in the valve.

Abstract: Fishing apparatus adapted for use with fishing accessories comprising a tackle box with an opening extending through an upper end and forming an inside wall. A first attachment means is disposed generally on a portion of the inside wall in the tackle box. The apparatus includes a container having outside walls generally surrounding a container opening with the container opening intersecting the upper end and being sized for receiving fishing accessories. A second attachment means includes a portion connected to the outside wall of the container. The second attachment means and the first attachment means each are adapted so that the second attachment means is removeably connectable to the first attachment means for removeably connecting the container to the inside of the tackle box.
