Title: Carburetor throttle valve flow optimizer
Inventor: PETERSON LONN M
IPC: F02M9/06
Filed: 1998-04-07
Abstract: An aerodynamic piece (48) for use with a carburetot having a barrel or round slide throttle valve (10). The piece (48) is formed as an insert which abuts the undersurface (15) of the slide (10).

Patent CA-2238187-A1 (CA)
Inventor: TRINK EDDY H
IPC: H04M3/36
Filed: 1997-10-01
Abstract: The switch capacity prediction process of the present invention collects operational measurements from the cellular switch. These operational measurements indicate the frequency of the call events processed by the switch. The other input/output (I/O) time used by the call processor to process messages not related to call processing is separated from the call processing I/O time. A relationship between the other I/O time and the sum of the call processing time and call processing I/O time is determined. A weighted average is determined from the summation of the products of: the frequency of events and the call processing time, the frequency of events and the call processing I/O time, and the other I/O time. The weighted average is then divided into the call processor occupancy time, in hours, to determine the switch capacity.

Inventor: LIETHEN FREDERIC J
IPC: A01K39/01
Filed: 1999-04-22
Abstract: A selective nectar dispensing system for use with a bird feeder. The nectar dispensing system includes a pivot assembly which has a counterweight at one end and a feeding port restricting portion at another end. The pivot assembly is operable between a closed blocking position and an open feeding position. The counterweight normally biases the restricting portion to the closed blocking position and has a mass selected to both permit a feeding bird to move the restricting portion towards the open feeding position and to prevent movement of the restricting portion by an insect, thus providing selective access to the feeding port. The feeding port restricting portion is urged away from the feeding port against the force of the counterweight. Access to the feeding port is provided only when the feeding port restricting portion is urged away from the feeding port by the beak of a feeding bird in one embodiment and by the weight of the bird in another embodiment.
