Title: Squirrel shield device
Inventor: HARBEN MICHAEL
IPC: H02B1/06
Filed: 1996-05-01
Abstract: The invention relates to a shield which prevents squirrels or other animals from causing faults in power distribution substations. Switch and bus insulators are primary points of contact when a small animal crawls from a grounded, supporting structure across an insulator to an energized conductor. The present invention provides for a barrier on switch and bus insulators which prevents animals from coming into contact with a grounded structure and an energized conductor simultaneously, thus eliminating a ground path from the energized conductor through the animal to the grounded structure.
Patent CA-2222401-A1 (CA)
Inventor: WUNSCHE ROBERT ROY
IPC: C21B3/00
Filed: 1997-11-27
Abstract: The invention provides a novel preheating apparatus and method for preheating a ferrous scrap mixture prior to feeding the scrap into a metallurgical furnance primarily using heat recovered from hot waste gases emitted from the furnace exhaust port, and simultaneously reducing contaminants from the scrap and from the waste gases, with concurrent downward flow of hot waste gases and downwardly descending scrap. The apparatus has a chamber, including a top compartment with a cold scrap input for depositing cold scrap into the top compartment and a hot waste gas inlet in flow communication with the furnace exhaust port. The chamber also has a bottom compartment with a heated scrap discharging mechanism for force delivering the heated scrap into the furnace and a waste gas outlet in flow communication with a vacuum exhaust for evacuating spent waste gas. Gas permeable gates are disposed between each chamber compartment and sequentially operate between a closed gate position and an open gate position, for concurrently receiving a gravity fed charge of scrap from the cold scrap input in a closed gate position, and during a predetermined dwell period supporting the scrap charge while hot waste gas flows downwardly from the hot gas inlet in the top compartment, permeates through the scrap charge and through the closed gates, and flows out the waste gas outlet in the bottom compartment. The gates mix the scrap as it falls and serve to control the gravitational descent of the scrap charge from the top compartment to the bottom compartment on expiry of the dwell period.

Title: Poly fuses in cmos integrated circuits
Inventor: INIEWSKI KRIS
IPC: H01L23/525
Filed: 1998-07-03
Abstract: An integrated circuit fuse with a fuse element having an "open" state and a "closed" state. A fuse status indicator is provided to indicate whether the fuse element is "open" or "closed". A current driver is electrically connected between the fuse element and electrical ground. One input of a dual input multiplexer is electrically connected to the fuse status indicator. The multiplexer's other input receives a fuse status simulation signal. A simulation mode switching signal is applied to the multiplexer's select input. A fuse output signal is consequently provided at the multiplexer's output to simulate operation of the fuse element in either the "open" or the "closed" state. The fuse element can be opened by causing a current having a value exceeding a preselected minimum value to flow through the fuse element for a preselected minimum time. This is preferably accomplished by fabricating the current driver as an NMOS device having a size sufficiently large to conduct the minimum value current for the minimum time required to open the fuse element. Advantageously, a pre-driver is provided to rapidly turn the current driver on, upon receipt of a fuse opening signal.

Inventor: NUSBAUM PERRY
IPC: H04R1/10
Filed: 1997-01-15
Abstract: An audio enhancement system and method is provided wherein a wireless headphone system comprises a transmitter (40) and a receiver (30) including a synchronization device (109) which utilizes electromagnetic locating signals to locate the position of the receiver with respect to the transmitter. The transmitter for this system will broadcast a frequency modulated (FM) signal on a number of separate channels in the 900 MHz band range. Each channel will carry the same audio information, however, each successive channel will have its audio signal delayed by a preset time period, e.g., 50 ms, relative to the previous channel. The headset receiver (30), supporting position location signals, and associated hardware will select the appropriate channel depending on the listener's distance from the main loudspeakers. These channels are laid out such that when in a large venue, and if the proper channel is chosen, the sound received electronically over the wireless channel will be approximately in phase with the sound arriving to the listener from the main loudspeakers.
