Abstract: A snack food container comprises a blow molded extruded transparent polyvinyl chloride housing having solid wall  and base segments,  a token slot, and an opening through which a solid particulate snack food product is loaded into and removed from the housing.  A releasable seal on an interior surface of the housing covers the token slot. The sealed cap, token slot seal and housing maintain the food product in a sealed state prior to the cap being removed and/or the seal being released.   The housing is used as a token bank by inserting tokens through the released token slot after the food product has been removed from the housing and the seal has been released from the token slot.  In one embodiment  the  token  slot  is  a  pressure  sensitive adhesive strip adhesively attached to the housing, and in a second embodiment the slot is in the cap.  The housing contains visible promotional material unrelated to the snack food.

Title: Contact arm with internal in-line spring
Inventor: NAVARRE LAWRENCE G
IPC: H01H71/00
Filed: 1997-12-17
Granted: 2008-05-06
Abstract: A circuit breaker contact arm (56) contains a straight elongate through-slot (112) that runs generally lengthwise of the contact arm and is closed at both lengthwise ends. Adjacent each slot, a respective side wall (106, 108) of a cross bar (58) contains a bent slot (114) having a knee (116). A respective cylindrical blow-open pin (118) passes through all three of these slots. A small helical coiled spring (120) occupies the contact arm through-slot and is compressed between the blow-open pin and the end of the contact arm slot that is proximate a cross bar/contact arm hinge pin (110). The spring is laterally confined by the adjacent side walls of the cross bar so as to remain in the contact arm slot about which the contact arm swings. The spring acts between the blow-open pin and the contact arm to bias the blow-open pin in a direction away from the cross bar/contact arm hinge axis. When the blow-open pin is below the knees of the bent slots and the contact arm is closed, completing an interruptable circuit through the circuit breaker, the spring exerts force beneficial to good contact of the contact arm contact (54) with a fixed contact (52). By disposing the spring in the contact arm slot, space is used more efficiently.

Abstract: In a multiple-access communication system where a center station dynamically allocates upstream bandwidth to subscriber stations, upon receiving a reservation information from a subscriber station, the center station obtains an upstream resource usage information of a service corresponding to an identifier added to the reservation information from an upstream resource usage control means. When a value of a guaranteed upstream rate of the service is above a value of measured average upstream rate, an upstream bandwidth is allocated immediately upon receiving the reservation information. On the contrary, when the guaranteed value is below the measured average upstream rate value, the upstream bandwidth allocation to the reservation information is deferred, resulting in preventing degradation of service quality of other subscriber stations.

Patent CA-2278880-C (CA)
Inventor: HOOK RICHARD WAYNE
IPC: A01B61/04

Granted: 2003-04-15
Abstract: A spring trip standard for a tillage implement includes a coil spring freely and solely compressed between an upper spring-abutting surface on the mounting bracket and a lower spring-abutting surface on a casting which is connected by a transverse pivot to the mounting bracket. A tool supporting shank is bolted to the casting and biased downwardly into a ground working position by the spring. The casting includes an integral stop extending forwardly from the pivot. The stop contacts the bottom of the bracket when the shank is in the ground working position so that a tension link between the bracket and casting is eliminated. A spring guide through the coils is also obviated. A  relatively high initial trip force prevents unwanted tripping of the shank and prevents looseness in the shank pivot so the lateral position of the tool is maintained. The spring-abutting surface on the casting includes a spring receiving projection to help maintain the spring position relative to the shank. The projection is slotted to receive a special tool for compressing the spring for standard disassembly and reassembly. The special tool also facilitates replacement of a bushing and sleeve assembly in the pivot with only partial disassembly.
