  • Device for sensing internal temperature of meat in rotisserie
    Patent number: 6546846
    Abstract: A device is mounted on a rotary spit of a rotisserie. The spit has an external handle at one end, a rod, and a connection member at the other end releasably coupled to a drive source. The device comprises temperature sensing elements on a central portion of the rod; and a thermometer on the handle, the thermometer having a sensing rod inserted into the handle to be conductive with the temperature sensing elements. After the rotisserie is activated, an internal temperature of a meat impaled by the rod being roasted is sensed by the temperature sensing elements. Next, the internal temperature of the meat is conveyed to the sensing rod from the temperature sensing elements so as to be indicated on the thermometer.

  • Fume recovery methods
    Patent number: 6534020
    Abstract: Apparatus (10) for recovering fumes from a roofing kettle (12) includes a fan (72) for drawing air from the hollow interior of a housing (20). A conduit (34) extends through the housing front wall (22) and terminates in the hollow interior. A burner assembly (44) is disposed within the conduit (34) for providing a flame within the conduit (34). The housing side wall (30) includes a fresh air intake (78). A flexible metal hose (80) extends between the outer free end of the conduit (34) and the roofing kettle (12). Rotation of the fan (72) causes air to be drawn from the interior of the housing (20) and in turn through the fresh air intake (78), through the conduit (34) and the hose (80) from the interior of the kettle (12), and through the duct (46) and tube (58) of the burner assembly (44).

  • Guarding system of a credit card against unauthorized use
    Patent number: 6533179
    Abstract: A guarding system of a credit card against unauthorized use includes one or more sets of letter-and-number series composed of letters and numbers stored in a credit card, and the same letter-and-number series as those of the credit card are set up in the data archives of the computer of a credit card issuing bank. The computer of the credit card issuing bank checks whether or not the letter-and-number series of the credit card coincide with those in its archives and deciding whether to allow the trading finished or not. Besides, the computer of the credit card issuing bank can automatically renew the letter-and-number series of the credit card every time after it is finished in trading. Then, these renewed data are checked and stored in the credit card and in the archives of the computer, surely preventing the credit card from copied and used by illegally and fraudulently.

  • Jack assembly that may be lifted rapidly
    Patent number: 6530219
    Abstract: The present invention relates a jack assembly that may be lifted rapidly. A secondary shaft is mounted in a lifting column, and has a distal end screwed into an axial hole in the base. The main oil path is provided with a lower ball and an upper ball, and has a first oil hole connected to the oil hole of the secondary shaft, and a second oil hole connected to the inner oil chamber. The hydraulic oil pushes away the lower ball to flow through the first oil hole into the secondary shaft, so that the lifting column that has not worked may be lifted rapidly. The lifting column may work to increase the pressure of the hydraulic oil which flows through the second oil hole into the inner oil chamber, so that the lifting column may have a sufficient lifting force to lift an object.

  • Battery powered, riding, floor burnishing machine
    Patent number: 6530821
    Abstract: A riding burnishing machine (10) includes a battery pack positioned as low as possible in the chassis (12) between the front and rear wheels (14, 15) and removable in a horizontal movement direction while supported by the bottom by a pallet jack. A steering system includes steering shafts (58, 76) which are rotatable together while allowing relative pivotable movement therebetween and which are rotatably connected to the spindle (38) of the steerable rear wheels (15) through a jack shaft (44). The burnishing head is raised and lowered relative to the floor surface by an electric actuator (104) which pivots a linkage (92) through a connection allowing floating travel. The pressure which the treating member (16) engages the floor surface is controlled in response to the current level of the electric motor (86) which rotates the treating member (16).
