  • Patent number: 6686566
    Abstract: The present invention efficiently and safely combines directed air flow for drying and heat removal with panel infrared emitters that provide thermal energy for curing LPI solder mask and legend inks onto printed circuit boards being transported though an area with pneumatic and radiant processes occurring simultaneously. The internal geometric configuration of the apparatus and high velocity input air results in an airflow stream in relation to the panel infrared emitters that ensures any flammable vapors are kept separated from the infrared emitters.

  • Patent number: 6678606
    Abstract: A system and method are disclosed for detecting tampering with the software, software parameters, and calibration data used by a vehicle controller. During authorized installation of controller memory images, a hash function is applied to selected regions of controller memory to obtain stored hash values. Then, periodically during operation of the vehicle, the hash function is applied to the then-current contents of the controller memory to obtain calculated hash values. If the stored hash values stored do not match the calculated hash values, a fault is logged for future retrieval by service personnel.

  • Patent number: 6536074
    Abstract: A conversion valve arrangement for converting a vacuum cleaner from floor use to off-the-floor use. A valve door located in the suction duct leading from the nozzle body shuts off the suction airstream to the nozzle body when the vacuum cleaner is moved into the upright stored position. A projection on the motor housing located beneath the handle engages a resilient member cooperating with a crank arm on the valve door to close the valve door when the handle is moved to the upright position. The resilient member is comprised of a front valve arm and a rear valve arm pivotally linked together. The motion of the rear valve arm is transmitted to the front valve arm in one direction by a stop. The motion of the rear valve arm is transmitted to the front valve arm in the opposite direction by the stiffness of a spring disposed between them.

  • Patent number: 6042648
    Abstract: A vertical circuit board soldering apparatus for soldering printed circuit boards by immersing them in a molten solder bath. Air knives are employed to remove excess solder from boards leaving the bath. A displacement mechanism vertically dips the circuit boards. The mechanism comprises a parallelepiped frame that comprises two spaced apart parallel rails securing a sliding chassis therebetween. The chassis comprises three parallel spaced apart members. An upper member transversely extends between the rails while captivating a portion of each rail adjacent its ends. A parallel lower member depends from the upper member with an adjustable intermediate member therebetween. The intermediate member also transversely extends between the rails while captivating another portion of the rails. The intermediate member is coupled to the upper member by a screw jack that moves the intermediate member upwardly or downwardly to vary the distance therebetween to accommodate various board sizes.

  • Patent number: 5738328
    Abstract: A stabilizing lanyard with stirrup holds cameras and other devices requiring stabilizing firmly free of body movement when the attached device is held upward with the user having a foot in the stirrup on the ground and pulling upward to create an isometric pull for stabilization of the held device. The invention is useful for stabilizing still cameras, video cameras, firearms and other hand-held equipment requiring a stable environment. The device of the invention folds into a compact package easily carried in the camera case or in a user's pocket or slung from a firearm. The user of a camera can pan or swing the camera quickly in any direction or angle necessary to pick up subjects in action. A firearm can be turned to track a moving target for accuracy.

  • Patent number: 5528328
    Abstract: A camera filter quick release adapter has mobile thread grips in a lower unthreaded guide rim section of a ring fitting the female threads of a camera lens collar. The thread grips are operated to move inward and outward by release tabs above them in an upper section of the same ring. The two parts are attached by a backing and a circular bias spring holds them protruded outward through openings for each in the ring sections. The lower section does not have threads and slips inside the camera lens collar acting as a guide rim. For installing the adapter of this invention in the camera lens collar, the release tabs are manually depressed pushing the thread grips back from connecting with the camera lens collar threads until the lower section of the adapter seats in the base of the lens collar. The tabs are than released, the circular bias spring pushes the thread grips into the threads of the camera lens collar securing the adapter of this invention to the front of the camera lens.

  • Patent number: 5458306
    Abstract: A flat base pivotally attaches to the lower end of a mono or uni pod forming a foot to provide stabilization for a still or a video camera mounted on the upper end of the pod. One end of the foot is a flat platform on which a photographer can place the toe end of his/her own foot to further stabilize a camera during picture taking.

  • Patent number: 4316447
    Abstract: A food container apparatus for use in combination with a pressure cooker which enables food to be cooked with steam, while concurrently the food is browned on the upper surface thereof. The food container apparatus is received within an upwardly opening pressure cooker, with there being a boiler formed between the bottom of the food container and the bottom of the pressure cooker, and a vapor space formed between the top of the food container and the lid of the pressure cooker. An annular area is formed about the outer periphery of the food container and communicates the vapor chamber with the boiler so that steam generated at the bottom of the pressure cooker flows towards the vapor chamber in heat transfer relationship respective to the food container, and is exhausted through the pressure regulator located in the lid. A heavy heating plate at the top of the food container prevents condensation of steam from admixing with the contents thereof, and at the same time provides a heat sink.

  • Patent number: 4243142
    Abstract: A tape storage and display apparatus by which a plurality of tape decks are displayed to prospective purchasers, and at the same time theft of the individual tape deck is discouraged. The apparatus includes an open framework which forms a plurality of windows through which either side of the plurality of tape decks can be viewed. Each window is defined by the inner peripheral edge portion of a slot. Each slot slidably receives a plurality of tape decks therewithin. Each slot includes opposed pairs of flanges which slidably receive opposed marginal edge portions of the tape decks therewithin. The slots have one end which outwardly opens to permit the tape decks to be slidably removed therefrom. The outwardly opening end of the slot is closed by a lock means.

  • Patent number: 4013172
    Abstract: A card file holder for filing cards of various thickness and length comprising an upwardly opening U-shaped support member having a forward and a rearward wall. A foam rubber member has a forward and a rearward wall surface with one surface thereof glued to the rear wall of the support, while an opposed wall surface thereof is glued to a movable plate member. The plate member is urged toward the forward wall of the support so that cards of various thickness are captured in supported relationship between the movable plate member and the forward wall of the support.
