  • Patent number: 4627007
    Abstract: An automatic system for processing poultry carcasses such as turkeys and the like which vary in size and shape as they are being conveyed on a conveyor is disclosed. The weight of the carcass is determined by a weighting system and the relative position of a preselected portion of the anatomy of the carcass such as the anterior or posterior edges of the breast is ascertained by a photosensor as the carcasses are being conveyed. A data processing computer receives the weight and position data for each carcass and causes a tool such as a needle to inject a basting additive to move to a position where the tool can perform the desired task, i.e., insertion of the needle at the preselected position on the carcass. A measured amount of the basting additive is automatically injected depending upon the measured weight of each of the carcasses. The carcasses are removed from the conveyor at discharge points depending on the weight and rated quality of the carcass.

  • Patent number: 4605229
    Abstract: A mechanical toy dragstrip having a base, and a starting tower disposed on the base. As in drag racing, two parallel car tracks and two car loading or starting positions are provided. The starting tower is used to signal the beginning of the race by displaying, in sequence, red, yellow and green marbles which simulate the lights of a dragstrip "Christmas tree". The marbles roll down a path in the tower and are displayed in apertures to simulate lights. As the green marble is displayed, a set of starting flags raise automatically, and toy vehicles may be launched from sets of trigger assemblies. The toy is arranged such that the cars may be released manually upon perception of the green "go" marble or such that one of the cars is released automatically after display of the green "go" marble upon raising of the starting flags to race against the other car which is released manually.

  • Patent number: 4598331
    Abstract: A ground fault current interrupter circuit is provided in which open neutral and open ground conditions create actuation of the interrupter circuit, as well as a ground fault. This is achieved by utilizing a supplemental secondary winding on the differential transformer of a common type of ground fault interrupter circuit. An open neutral lead or an open ground lead produces a current flow through the supplemental secondary winding that induces a trip signal in the secondary winding to initiate opening of the power line. In a second embodiment the supplemental secondary winding induces a trip signal in the transformer only for an open ground lead, while tripping for an open neutral is achieved by directly gating an SCR switch. The circuit arrangements also protect against other conditions, such as a potential in excess of a predetermined voltage between the neutral and ground leads or a reversal of the input connections.

  • Patent number: 4567456
    Abstract: A resettable contact closing device opens a load circuit connected to a power line protected by a ground fault interrupter circuit, if the neutral conductor is broken. The contacts are closed by a mechanical reset actuator only if a solenoid is energized by a potential proportional to the line-to-neutral voltage to hold the actuator in a contact closing position. If the neutral conductor is broken, the solenoid will not be energized and the contacts, and hence the power line to the load circuit, will be opened.

  • Patent number: 4455721
    Abstract: An external clamping device for high pressure inflatable air bags utilizes opposed bracket members. An engaging structure, such as a set of teeth designed to grip the material of the inflatable air bag without damaging it, is formed adjacent one end of each of the bracket members. A stepped shoulder is formed at the other end of each of the brackets, so that when the opposing brackets are brought together the stepped shoulders abut one another to preclude pivoting of the bracket members during tightening. Tightening of the bracket members to firmly grip the air bag is achieved by a bolt threaded into openings intermediate the ends of the bracket members. When the bracket members are joined together, a connecting hole is formed for attaching the clamping device to a positioning arrangement.

  • Patent number: 4445428
    Abstract: A cooking grill structure for utilizing the heat from deep fat fryers has a grill plate and a heat pipe extending into the cooking oil. Water is utilized as the liquid medium in the heat pipe, and condensation is distributed over the grill plate to provide uniform heating and prevent accumulated forces. Distribution is achieved by a relatively small channel that uniformly spreads the heat while preventing the production of unduly large pressure forces. To achieve greater transfer of heat from the cooking oil to the liquid medium in the heat pipe, heat transfer assistance approaches, such as fins or small diameter tubes to provide a flash boiler effect may be used. Also, more than one heat pipe may be used, and the grill plates may be interlocked to provide a continuous grill surface.
