Title: Cooking apparatus for producing grill stripes on cooked products
Inventor: FORNEY ROBERT B
IPC: A47J37/04
Filed: 1991-08-08
Granted: 1995-02-28
Abstract: A belt grill or belt cooking apparatus, of the general type previously known for rapidly cooking meat, grilled sandwiches, etc. in a travelling path through the apparatus, has improvements enabling the belt cooking grill to impart grill stripes or grill pat-terns on the product as it is cooked. In one embodiment the improved belt cooking apparatus has upper and lower heat platens (34, 36) with ridges or other types of embossings (46), with the moving belts (12, 14) being formed of a flexible material capable of good heat transfer and good wear resistance at elevated temperatures. The ridges or embossings (46) press the belt into the food product (32), causing greater heat transfer at the ridges than between them, and thus forming a series of grill stripes on the pro-duct while the product is also cooked. In another embodiment, the belts (80, 82) are formed of stainless steel, with corrugations, embossings or ridges (84, 88) which press directly against the moving food product as it is cooked, to effect grill stripes due to greater heat transfer along the lines of pressure.

Abstract: EXTERIOR AUTOMOTIVE LAMINATE WITH    PRESSURE-SENSITIVE ADHESIVE          Abstract of the Disclosure A flexible decorative sheet for use in surfacing an automobile body panel includes a first polyester carrier sheet having a high gloss surface, a clear coat of a weatherable    optically-clear    polymer    containing fluorocarbon resin and an acrylic resin coated on the surface of the first carrier sheet, a tie coat on the clear coat, and a color coat containing a chlorinated polymer with dispersed pigments cast on the tie coat and dried.  A pressure-sensitive adhesive layer is formed on a second polyester carrier sheet and then laminated to the exposed   face   of   the   color   coat   to   form   a pressure-sensitive, adhesive-backed composite paint coat between the outer carrier sheets which form protective removable backing sheets for the resulting laminate.  The decorative sheet is applied to a substrate panel by pressure-sensitive adhesive bonding techniques, with the clear coat serving as a glossy, weatherable protective outer  layer  for  the  underlying  color  coat.    The PVC-containing  color  coat  enhances  room  temperature elongation of the finished film to enable application of the laminate to three-dimensionally contoured surfaces. The resulting paint finish has a defect-free, weatherable and durable  outer  surface with  high  gloss  and high distinctness of image, meeting requirements for exterior automotive use.

Title: Quasi-resonant diode drive current source
Inventor: ORTIZ JOE A
IPC: H05B44/00
Filed: 1993-04-14
Granted: 1998-07-14
Abstract: A quasi-resonant diode drive current source provides high power pulsed current that drives light emitting diodes, and the like. The pulsed output current of the quasi-resonant diode drive current source is sensed, and is regulated by a control loop to a level required by the light emitting diodes. In a specific embodiment of the invention, a zero-current-switched full wave quasi-resonant buck converter is described that provides a high amplitude pulsed output current required to drive light emitting pump diodes used in a solid state diode pumped laser. The use of a quasi-resonant converter as a pulsed current source provides a much higher conversion efficiency than conventional laser current sources. This higher efficiency results in less input power drawn from a power source and cooler operation, resulting in a higher reliability current source.

Granted: 2000-01-18
Abstract: A microcell unit, in a cellular telephone system using digital signal processing BSs, is digitally connected to a macrocell, via a metallic link, such as a twisted pair. The microcell includes a plurality of radio channel units (RCU), to provide voice connectivity to mobile subscribers (MS), which are under control of a radio control complex (RCC) located in the macrocell. Several time slots of the macrocell TDM bus, through which the RCC exerts control of the RCUs, are remoted to the microcell thereby enabling control of the RCUs at the microcell location by the RCC of the macrocell. This remoting action is achieved, via a remote time division multiplex (TDM) circuit pack which enables the RCC to communicate with the RCUs as if they were located within the macrocell.

Title: Carrier for stacked articles
Inventor: SCHUSTER RICHARD L
IPC: B65D71/36
Filed: 1993-09-24
Granted: 2004-09-21
Abstract: A carrier containing a plurality of layers of articles, such as beverage cans, arranged in stacked end-to-end fashion. The carrier(10) is fully enclosed and is formed with overlapping top panel flaps (16, 18) which produce an area of double thickness between handle openings in the flaps. A reinforcing sheet (40) on the underside of the top panel in the double layer area protects against tearing while stress relief lines (34, 36) in the form of score lines extending from the ends of the handle opening to the corners of the carrier (10) provide for distribution of lifting and carrying stresses. A separator sheet (70) preventing direct contact between stacked articles extends between layers and may include distortable areas (72) aligned with the articles. Downward pressure on the upper layer (C1) causes the bottom of an article to force the distortable area into a recess in the top of the next lower article.

Title: Personal communication using intelligent terminals
Inventor: CARLSEN RALPH
IPC: H04Q3/00

Granted: 1999-08-31
Abstract: An intelligent terminal (which can be a telephone (101-2, 101-3), a facsimile machine (101-4), or similar device (101-1)) is arranged so that (a) it can store information indicating when (e.g., date and time) a particular subscriber last was present at the terminal, and (b) the stored information can be retrieved from the terminal remotely, preferably without completing a conventional call to the terminal. A central processor (114) contains, for each subscriber, a list of theintelligent terminals that have been pre-designated for use by that subscriber, and has the ability to query terminals on the list. In response to a call placed to the subscriber by dialing the subscriber's unique personal number, specific intelligent terminals on that subscriber's list are queried by the central processor to determine when the subscriber was last present at each terminal. The central processor then generates a control signal such that the call is then completed to the particular terminal that was most recently visited by the subscriber.

Abstract: A waveguide for projecting a longitudinal acous-tic wave of wavelength .lambda. from an ultrasound energy source toward a target area.   The waveguide has at least one tubular channel.  The channel has inwardly tapered, conical inlet and outlet ports separated by a venturi.  The inlet port taper defines a sharply rimmed entry orifice around the inlet port.  A separation distance equal to one wave-length .lambda. is maintained between the source and the wave-guide's inlet port.   The waveguide shears off a cross-section of the wave emitted by the energy source and ejects it at accelerated velocity toward the target area.   The channel has a length L and the venturi has a diameter D, such that the waveguide has an emitted beam angle equal to 2  (tan-1  (D/L)).    Preferably,  a  plurality  of  tubular channels are aligned concentrically around and longitudi-nally parallel to the one tubular channel,  each channel having a selected length and a selected diameter.   The channels are preferably circular in cross-section,  with their outlet ports located in an inwardly scalloped front face of the waveguide.

Abstract: The invention concerns an inhaler device (1) having a hollow tubular member (2, 102, 402) connected to a chamber (5, 105, 405). The tubular member has a first opening (3, 103, 203) at one end through which air can be sucked and the chamber (5, 105, 405) has a hole (4, 104, 204) therein for entry of air. When air is sucked through the first opening, air enters the chamber through the hole swirls and moves towards the first opening (3, 103, 203). To maintain or increase the swirling effect of the air a single restriction (10, 110) is arranged between the opening and the hole (4, 104, 204). A powdered substance (8) within the chamber is picked up by the swirling air within the chamber and is uniformly and finely divided by the swirling effect of the air. The effect can be enhanced by adding a movable element (6) such as a ball inside the chamber (5) and/or by providing a central core element (112, 412) inside the chamber.
