Abstract: A shelf system comprises flat cantilever shelf-supporting brackets and a sheet metal shelf.      Each cantilever shelf-supporting bracket includes an upper edge surface formed with (i) a first notch defining a sloping bottom edge surface and a tongue delimiting between them a cavity, and (ii) a second substantially rectangular notch. At each end of the shelf, the sheet metal is bent downwardly at right angle to form a flange and thereby define a corner.      The shelf further comprises elongate transverse members made of sheet metal, bent lengthwise at right angle, and each fitted and secured in one corner, under the shelf. Cut and formed in the sheet metal of each elongate transverse member is (a) a first hollow box-like mounting element adapted to slide on the sloping bottom edge surface of the first notch of an associated shelf-supporting bracket and open to receive the tongue of this first notch and thereby enable positioning of the first mounting element in the cavity between these sloping bottom edge surface and tongue, and (b) a second hollow box-like mounting element adapted to be received by the second rectangular notch of the associated shelf-supporting bracket after the first box-like mounting element has been positioned into the cavity.

Title: Frequency sharing in multiple radiotelephone systems
Inventor: D AVELLO ROBERT F
IPC: H04B15/00
Filed: 1992-12-31
Granted: 2001-07-03
Abstract: A portable radiotelephone (101) communicates with both a cordless base station (115) servicing a local coverage area and a cellular base station (105) servicing a wide coverage area over cellular frequency channels. Each of the portable radiotelephone (101) and the cordless base station (115) scans the available channels based upon a measure of interference or a type of service on the cellular frequency channels to generate separate priority lists for the cellular frequency channels. Each of the portable radiotelephone (101) and the cordless base station (115) ranks the available channels in its own priority list from best to worst. The priority lists from each of the portable radiotelephone (101) and the cordless base station (115) are combined in the portable radiotelephone (101) or the cordless base station (115) to form a master priority list. The clearest available channel from the master priority list is assigned to the portable radiotelephone (101) and the cordless base station (115) for communicating in the cordless telephone system. Thus, interference to and from the cellular system and other users of the cellular frequencies is minimized and the need for frequency planning is eliminated.

Title: Interactive system for producing, storing and retrieving information correlated with a recording of an event
Inventor: WEBER KARON A
IPC: G06F3/0488
Filed: 1994-07-28
Granted: 1998-09-22
Abstract: An interactive processor-controlled system for entering and storing user information about an event that is being concurrently recorded in real time correlates the user information to user-requested addresses, such as time values stored with the recorded signals. The system includes a recording device for producing signals indicating recorded event data that includes periodic addresses, each of which indicates a portion of the recorded signals. An address source, such as a clock, is connected for providing address values to both the processor and the recording device. Using a pen-based user interface in one embodiment of the system, the system user specifically requests an address value in order to correlate user information to the signals being concurrently recorded. In response to a request for an address, the system establishes a spatial region on the display, called a time zone, into which the system user may enter information, in the form of handwritten strokes, about the event. All information entered into a time zone is stored and correlated with the address value represented by the time zone, in effect creating a log of the recorded event that may be used to access the portions of the recorded signals. While time zones are created by the user in sequential time order, information can be entered in to time zones in any sequence, thereby facilitating editing and annotation of previously-entered information. The ability to correlate the recorded signals to keywords designated in the user-supplied information is also provided.

Filed: 1995-03-30
Granted: 2004-10-26
Abstract: A process for making a length of rubber tubing with axially spaced circumferentially corrugated flexible segments from a sleeve of uncured rubber and the product resulting therefrom. An end length of a sleeve of uncured rubber is placed over an end portion of a forming mandrel and an external form is placed around the sleeve end length.      Rudimentary corrugations are then formed in the end length after which the sleeve is moved axially along the forming mandrel so that a new length portion of the sleeve is placed in a forming position. Then using the external forth, rudimentary corrugations are formed in the second length portion of the sleeve. These steps are repeated until the desired number of axial length portions in the sleeve are provided with rudimentary corrugations. The resulting product is then cured to forth a length of rubber tubing with a plurality of axially spaced circumferentially corrugated flexible segments.

Abstract: Improvements in piston-based ventilator design and operation are described.  An individual compensation of force dissipation within the gas delivery system is effected, so that the desired gas pressure is delivered to the patient airway without the necessity for monitoring the actual pressure and using it as feedback. A piston is dimensioned slightly less than the chamber wall of the pump to define a gap through which an acceptable amount of gas may leak but which eliminates the need for a physical seal, thereby minimizing the frictional resistance within the pump.
