Title: Beverage dispenser with automatic cup-filling control
Inventor: SALSICH TONY
IPC: B67D1/00
Filed: 2005-05-16
Abstract: A beverage dispenser for filling a container preferably has a nozzle through which the beverage is discharged and a pivoting lever located underneath the nozzle that detects the placement of a container so as to regulate the actuation of the dispenser. A conductive probe is in line with the discharged beverage stream, the lever also being conductive. A signal generator generates a varying-over-time signal that is applied to the probe or lever. As a result of beverage overflowing the container, the beverage stream establishes a conductive path between the probe and lever. The signal through this conductive path is compared to the signal produced by the signal generator. If the signals are substantially identical for a select period of time, the dispensing system is considered to be in an overflow state, and beverage dispensing is terminated.

Title: Cover-plate expansion assembly method and device therefore
Inventor: PARKER GLEN C
IPC: B23P19/027
Filed: 1999-10-01
Abstract: An assembly technique for closing a movable socket (10) without the need to deform or displace any portion of the socket housing (12), thereby allowing for the use of fully hardened socket housing materials. The internal components of the movable socket are installed within the housing through an opening (16), and a conical cover-plate (66) is positioned over the components, within the opening. An assembly tool (100) configured to exert pressure on the conical cover-plate is brought into engagement with the plate, and a downward load is applied, expanding the plate to seat within a circumferential groove (22) in the housing. The assembly tool includes a specifically contoured face (109) which alters the angle at which pressure is exerted against the expanding conical cover-plate as the plate deforms to a generally planar configuration, closing the opening in the housing. Once expanded, the cover-plate seats within the groove formed in the interior surface of the housing, thereby securing the internal components within the housing.
