Abstract: A vertical cavity surface emitting laser (VCSEL) operable as a signal emitter and a silicon photodetector adapted for receiving light signals co-mounted in a common canister. Also containable is a four lead header and an isolating ceramic spacer. The canister can be electrically connected to a first lead from the header. The isolating ceramic spacer is adapted for mounting of the VCSEL above the level of the photodetector within the can. The VCSEL is electrically connectable to a second and third lead from the header and the photodetector is electrically connectable to the second and a fourth lead from the header. Co-packaging of a VCSEL and photodetector in common device canisters can yield about a 20:1 contrast ratio between an object's presence in front of the sensing system. A small pattern necessary for high accuracy is provided by the system and no barrier is necessary between the emitter and detector.

Abstract: In one embodiment, a beverage container is disclosed. The container includes a bottom portion formed to contain a consumable fluid and a top portion fixably coupled to the bottom portion so as to further contain the fluid and whereby the top portion and bottom portion are not detachable. The top portion comprising a drinking spout having a one-way valve, wherein the one-way valve opens to expel fluid from the bottom portion through the spout when a negative pressure is applied to the spout and the one-way value closes to substantially prevent fluid from leaking out from the bottom portion through the spout when negative pressure is not applied to the spout. Methods for fabricating such container are also disclosed.

Abstract: The achievement and economical method of the cleanout of the service tank, providing greater safety due to the V-Shape bottom of the service tank of a hot oil unit.

Abstract: A fluid pressure operated reciprocating conveyor in the form of a pan feeder comprises a base, an elongated conveyor trough reciprocably mounted on the base, a drive cylinder connected between the base and trough, a constant volume pump, a solenoid-operated reversing valve connected between the pump and the drive cylinder to direct pressure fluid to opposite ends of the cylinder to reciprocate the trough through a stroking range in a forward stroke and in a rearward stroke at a substantially higher speed than the forward stroke. Forward and rearward limit switches connected to the reversing valve are automatically operable by the moving trough to reverse the drive cylinder at opposite ends of the stroking range.
