Patent number: 6980894Abstract: The present invention provides methods for preventing low train voltages and managing interference, thereby improving the efficiency, reliability, and passenger comfort associated with commuter trains. An algorithm implementing neural network technology is used to predict low voltages before they occur. Once voltages are predicted, then multiple trains can be controlled to prevent low voltage events. Further, algorithms for managing inference are presented in the present invention. Different types of interference problems are addressed in the present invention such as “Interference During Acceleration”, “Interference Near Station Stops”, and “Interference During Delay Recovery.” Managing such interference avoids unnecessary brake/acceleration cycles during acceleration, immediately before station stops, and after substantial delays. Algorithms are demonstrated to avoid oscillatory brake/acceleration cycles due to interference and to smooth the trajectories of closely following trains.Type: GrantFiled: December 19, 2003Date of Patent: December 27, 2005Assignee: San Francisco Bay Area Rapid TransitInventors: Susanna P. Gordon, John A. Evans

Patent number: 4869145Abstract: A musical instrument comprises a tremolo apparatus which may be converted from a semi-floating mode in which a spring urged stop engages a movable sustain block in some positions thereof to a free-floating mode in which the spring-urged stop does not engage the sustain block in any position thereof. The spring-urged stop is provided with a releasable latch for latching it into the non-engaging position, the latch including a bayonet joint. An indicator apparatus indicates the position of the sustain block relative to a fixed reference target, to enable rapid location of the sustain block for the tuned position of the strings of the instrument. A pusher block of magnetic material is provided for insertion between the sustain block and the spring-urged stop for assistance in urging the spring to the position in which it is locked out of engagement with the sustain block, to establish the free-floating mode.Type: GrantFiled: November 23, 1987Date of Patent: September 26, 1989Inventor: John A. Evans

Patent number: 4581253Abstract: A process for preparing a proppant charge comprising individual sand particles coated with a pre-cured thermosettable resin. Sand is mixed with melted resin, and the resin-coated sand is heated under conditions which cure the resin. Mixing is carried out with sufficient mechanical shearing action to limit agglomeration of the resin-coated sand particles.Type: GrantFiled: December 7, 1984Date of Patent: April 8, 1986Assignee: Acme Resin CorporationInventors: John A. Evans, James Sharp

Patent number: 4489140Abstract: A composite brazing material is described, composed of a layer (usually an ingot) of high manganese content aluminum alloy (3000 series alloy; the "core") and a layer of high silicon content aluminum alloy (4000 series alloy; the "cladding") with a layer of aluminum alloy having the following composition:______________________________________ silicon 6.8-8.2 wgt. % iron up to 0.8 wgt. % copper up to 0.25 wgt. % manganese up to 0.10 wgt. % zinc up to 0.20 wgt. % other elements up to 0.15 wgt. % aluminum balance ______________________________________disposed between the cladding and core layers and in contact with both. Subsequent hot rolling of the multi-layer composite produces a good bond between the core and the cladding through the intermediate layer. The resulting brazing material has the external properties of a simple two-layer composite of core and cladding without the intermediate layer.Type: GrantFiled: June 24, 1982Date of Patent: December 18, 1984Assignee: Atlantic Richfield CompanyInventors: Daniel L. Pulliam, John A. Evans, David L. Wilbur, Robert D. Fox
