Patent CA-2282413-A1 (CA)
Inventor: MILLER ALLEN D
IPC: B65D83/38
Filed: 1997-08-28
Abstract: An aerosol dispenser (10) and a refill cartridge (18) therefor.   The aerosol dispenser (18) has an outer housing (12) adapted to preferentially fit a user's hand with the front (14) of the dispenser (10) presented away from the user. An actuator arm (52) is hinged to the outer housing (12). A refill cartridge may be removably inserted into the outer housing (12) from beneath. The cartridge (38) includes an aerosol can (18) having a manually activatable valve (28) and an upwardly directed nozzle (20), which extends through a nozzle port in the actuator arm (52) when the cartridge (38) is inserted within the outer housing (12). A user can activate the valve (28) by hand by pushing the actuator arm (52) downwardly with a finger. The outer housing (12) is designed to be held on a level surface during such activation. The nozzle (20) includes a longitudinally extended delivery tube (22) in fluid communication with the pressurized material in the can (18). The delivery tube (22) communicates with a longitudinally extended exit chamber (24) having a spray orifice (26). The longitudinal axis of the exit chamber (24) is angularly displaced frontwardly from the longitudinal axis of the delivery tube (22).

Title: Caldron
Inventor: IMAMURA KAZUHIKO
IPC: A23L11/00
Filed: 1999-09-09
Abstract: The caldron of the invention comprises a cylindrical caldron main body having a raw material charge port for charging a water-added raw material to be boiled and a discharge port for discharging a boiled raw material, both ports being disposed near to both the closed ends of the caldron main body and at least one steam injection pipe installed in the caldron main body and having a plurality of injection ports for injecting steam-and preferably oxygen-free streams for boiling the raw material, wherein the injecting direction of the steam injected from the injection ports is inclined so that the steam is supplied in the circumferential direction of the caldron main body.      As a result, the caldron of the invention can prevent the water-added raw material to be boiled such as bean juice and the like from being unevenly boiled, eliminate the adverse affect caused by the steam remaining in the caldron main body, lower the pressure in the caldron main body, properly control the raw material fed in the caldron main body, uniformly and sufficiently transmit the heat of the steam to the raw material so that it is evenly and sufficiently heated, whereby the boiled raw material such as bean juice and the like is manufactured, from which soybean milk of high quality preferably containing no oxygen mixed therewith and dissolved therein can be manufactured.

Title: Composition pour le traitement de surfaces d'objets plats en vue de produire des points de separation predetermines dans une pluralite de tels objets au moins partiellement superposes
Inventor: MAEDER CARL CONRAD
IPC: B42F21/00
Filed: 1998-04-07
Abstract: La composition selon l'invention (3) renferme un agent antistatique et un agent de glissement. Une surface d'un objet plat (2) traitée par une telle composition se comporte dans une pluralité de tels objets superposés au moins partiellement, comme une zone de séparation prédéterminée. L'agent de glissement permet de réduire le coefficient de friction entre la surface traitée et la surface d'un objet adjacent et, par conséquent, le frottement par adhérence entre les deux objets. L'agent antistatique permet de réduire la charge électrostatique de l'objet considéré et, par conséquent, l'adhérence entre les objets obtenue par charge électrostatique. Ces deux effets se manifestent conjointement de telle façon que dans une pluralité d'objets plats superposés, chargés électrostatiquement par action d'un champ équipotentiel, une force de translation (11), de composante parallèle aux surfaces principales des objets, produit un déplacement au point de la surface traitée.

Inventor: BERGREN MARK H
IPC: H04W36/00
Filed: 2000-07-12
Abstract: The system for wireless communication connection handoff service addresses the CDMA radio congestion problem from the mobile switching center point of view, thereby providing a unified approach to the problem of access failures for CDMA wireless communication service. In operation, the mobile subscriber station forms a message and forwards it to the mobile switching center to indicate the signal strength of the various base stations that have responded to the access probe. The mobile switching center saves this data for later use when the mobile subscriber station moves out of range of the initially selected base station. The mobile switching center reviews the stored data and, if a CIC is available to one of the identified base stations, the channel is allocated and the stored data is flushed. Thus, the need for another probe sequence is avoided and the initially provided base station signal strength data is reused to process a call handoff.

Title: Disc brake housing
Inventor: RANCOURT YVON
IPC: F16D69/00
Filed: 2000-07-25
Abstract: An annular disc brake assembly has a housing mounted to a vehicle and a rotor disk mounted to a wheel of the vehicle. A pair of annular brake shoes are in frictional engagement with the rotor disk during a brake action, and resiliently supported by the housing and a supportive structure of the vehicle, respectively. The housing includes an annular radial wall having an annular ridge on the inner surface to abut the brake shoe which is supported by the housing so that during the brake action uneven and various forces applied to the brake shoe will cause local portions of the brake shoe oscillating about the contact point. The oscillation will be damped by damping pads placed between the housing and the brake shoe. The housing has a plurality of axial link members extending from the annular radial wall. The axial link members include clip means at each distal end for clipping onto the supportive structure of the vehicle. The housing used in the brake assembly improves the brake assembly regarding the reduction of vibration and brake squeal, and simplifies the assembling procedure.
