  • Patent number: 5097637
    Abstract: An integral abrasive cutting tool comprising a multiplicity of equally spaced parallel coaxial abrasive cutting discs is formed by rotating a cylindrical mandrel coated with a matrix of abrasive powder in a metal in a fluid bath. A wire is aligned tangentially with the coating and voltage pulses are applied therebetween while the wire is fed in its lengthwise direction past the coating. The wire is translated axially to each of a plurality of disc spacing locations and, at each such location, translated radially to effect electro erosion of the coating forming a channel therein. An abrasive cutting disc is thereby provided between each pair of successive channels.

  • Patent number: 5097640
    Abstract: A frame for a projection screen or the like may be fabricated of elongated round tubular members running one direction and polygonal (preferably rectangular) cross section members running in the other direction connected together into a grid by clamps at their intersections. The clamps are parallel plates affixed to the parallel surfaces of the polygonal support members and have a rounded groove in an edge generally conforming to the rounded cross section. Clamp means to hold the round members in the grooves are conveniently formed of U-bolts which are secured to flanges generally normal to the planar surfaces of the bracket.

  • Patent number: 5097648
    Abstract: A bag evacuating and closing apparatus having two opposing jaws which face ends that move toward one another. The jaws encompass a top closure of a bag package to be sealed. The jaws have hollow spaces open toward one another which are surrounded by frames with sealing jaws disposed in the hollow spaces; the hollow spaces form a chamber that receives the top closure of the bag package. A sealing rib protrudes from one face end of the two frames and is interrupted in a middle region of the frame part at which the closure fold protrudes between the jaws. In this region, suction openings are disposed in the frame parts of both jaws; these suction openings pull two walls of the top closure tightly against the frame parts. After the top closure of the bag package has been tightly encompassed, air is extracted from the bag package by a vacuum, and subsequently, the top closure of the package is tightly sealed by the sealing jaws which form a sealing seam to close the upper end of the bag.

  • Patent number: 5097656
    Abstract: In order to reduce turbine engine exhaust noise while simultaneously reducing anti-surge airflow noise, a combination noise reduction apparatus or tube (10) is provided having a series of holes (26) in its side. The tube (10) is in communication with a source of anti-surge air through an anti-surge air outlet (22) to be delivered into the exhaust airflow in an exhaust duct (12). The tube (10) diffuses the anti-surge air, shields the noise of the anti-surge air by dissipating the acoustic energy within the tube (10), and provides for an even distribution of the anti-surge air into the exhaust airflow. As a result, a temperature discontinuity is created in the exhaust duct (12) which results in an acoustic impedance that reflects acoustic noise back to the source of the noise.

  • Patent number: 5097672
    Abstract: A blow-off duct is rotatably mounted on an air-conditioner. A human body detection device is provided at the blow-off duct in order to detect the presence of a person to be air-conditioned and then to identify the moving direction thereof. Comfortable localized air-conditioning can be realized since a wind direction control device controls a duct drive device of the blow-off duct in response to a human body detected signal and movement signal outputted by the human body detection device, and thus rotating the blow-off duct in accordance with the movement of the person to be air-conditioned.

  • Patent number: 5097675
    Abstract: An air flow control for a multi-port refrigerator duct that conveys cold air from the evaporator chamber to a plurality of storage chambers within the fresh food compartment. The duct has a baffle providing individual branches for each storage chamber such that each is substantially coupled directly to the evaporator chamber so that a change in air flow in one branch does not significantly affect the flow in the opposite branch. A manually operated control is mounted within the fresh food compartment and has a face plate with a vent aligned with a liner input aperture communicating with the duct. A shutter disc is captured between the face plate and the liner, and has a tear drop opening. Rotation of the shutter disc alters the location of the tear drop opening and, thus the size of the passageway through the air flow control.

  • Patent number: 5097676
    Abstract: Apparatus and process are disclosed for increasing the sorbate content of a sorbent liquid beyond the level possible at a defined absorbing temperature and pressure. Specific useful results obtainable thereby are an increase in the efficiency of thermally actuated absorption processes such as absorption compression and absorption heat pumping. The improvement allows greater temperature overlap between generator and absorber, ambient responsive performance, and virtualy elimination of the need for rectification. Referring to FIG. 1b, the useful result is obtained by pressurizing (1) and splitting (2) the sorbent to supply an absorber (3) with cooling (4) and a generator (5) with heating (6), and routing (7) generator sorbate vapor to the absorber to achieve increased dilution therein.

  • Patent number: 5097686
    Abstract: A security locking system primarily for use in the locking of a threaded retaining member onto a vehicle wheel. In one embodiment, the threaded retaining member may adopt the form of wheel lug nuts which are threaded onto the threaded studs of a vehicle wheel. The locking system comprises a sleeve or so-called "cover" extendable over the retaining member. A locking mechanism is mounted in an end wall of the sleeve. The locking mechanism is provided with a locking element which is extendable radially for engagement with a groove in the wheel lug and provides a positive locking action. The locking mechanism is provided with a cylindrically shaped key slot and has projections in the key slot. A key is provided with certain grooves alignable with the projections in the key slot to receive the key such that only the key having the aligned and properly sized recesses can be used to open and close the locking element. In this way, a conventional tumbler system normally used in most vehice wheel locks can be avoided.
