Patent CA-2180490-C (CA)
Title: Miniature pump sprayer
Inventor: MONTANER PEDRO PARES
IPC: B05B1/00
Filed: 1996-07-04
Granted: 2000-09-05
Abstract: A ventless miniature pump sprayer comprises a reciprocable plunger head extending outwardly of an open end of a tubular member divided into an upper sleeve section and a lower container section for a liquid to be sprayed. A dip tube integral with the member extends into the container, and a pump cylinder and hollow inlet tube integral with the member extend into the sleeve section. An integral shipper seal is molded in the inlet tube and a coaxial rod within a hollow piston on the plunger cooperates with the inlet tube for controlling the inlet and, during initial actuation of the plunger, pierces the shipper seal and has a groove or a rib thereon which establishes an air passage through which unwanted air from the pump chamber is ejected into the container to aid in pump priming.

Abstract: A harvesting method which removes chaff and weed seeds from the field with the harvested grain, and separates the chaff, grain leavings and weed seeds from the grain in a stationary yard plant. The chaff, grain leavings and weed seeds are compacted and crushed in a mill for use as animal feed.  Simplified harvesters have augmented holding tanks, one version of which can be attached to (and detached from) existing farm tractors.  A specific integrated yard plant separates and cleans harvested grain and compacts and crushes chaff, grain leavings and weed seeds.

Title: Apparatus and method for isdn provision verification
Inventor: BAKER ALBERT D
IPC: H04Q11/04
Filed: 1997-01-30
Granted: 2000-09-05
Abstract: Provisioning a Central Office (CO) Basic Rate Interface (BRI) access is a complex procedure which involves hundreds, and potentially thousands, of parameters that must be asserted to configure the CO for a particular user's service profile. In such a complex procedure, errors in the provisioning may be introduced which are difficult and costly to detect and correct. To solve this problem, a provisioning tool which exercises BRI lines i.e., digital subscriber lines (DSLs) from a CO to a premises switch is defined which validates that transport related restrictions and permissions are properly administered at the CO. This is achieved by the system calling itself over such lines, and varying the types (e.g., voice, digital, data, 3.1 kHz audio, et al.) of call attempts that are placed to ensure that all lines support the intended services.

Title: Method and apparatus for providing enhanced pay per view in video server employing coarse-grained striping scheme
Inventor: OZDEN BANU
IPC: H04N7/173
Filed: 1997-01-31
Granted: 2001-07-24
Abstract: A method and apparatus are disclosed for providing enhanced pay per view in a video server. Specifically, the present invention periodically schedules a group of non pre-emptible tasks corresponding to videos in a video server having a predetermined number of processors, wherein each task begins at predetermined periods and has a set of sub-tasks separated by predetermined intervals. To schedule the group of tasks, the present invention divides the tasks into two groups according to whether they may be scheduled on a single processor. The present invention schedules each group separately. For the group of tasks not scheduleable on a single processor, the present invention determines a number of processors required to schedule such group and schedules such tasks to start at a predetermined time. For the group of tasks scheduleable on a single processor, the present invention determines whether such tasks are scheduleable on the available processors using an array of time slots. If the present invention determines that such group of tasks are not scheduleable on the available processors, then the present invention recursively partitions such group of tasks in subsets and re-performs the second determination of scheduleability. Recursive partitioning continues until the group of tasks is deemed scheduleable or no longer partitionable. In the latter case, the group of tasks is deemed not scheduleable.

Title: Multipoint video conference controlling method and system capable of synchronizing video and audio packets
Inventor: FUKUOKA HIDEYUKI
IPC: H04N21/44
Filed: 1997-02-06
Granted: 2000-06-27
Abstract: In a multipoint video conference controlling system which is supplied with video packets and audio packets from conference terminals, which multiplexes the video packets to produce a composite packet, and mixes the audio packets to produce a mixed audio packet, a sequence number collating device collates the sequence numbers of the video packets and the audio packets to produce a coincidence signal when the sequence numbers of the video packets and the audio packets coincide with each other. Video and audio transmitting devices transmit synchronously the composite packet and the mixed audio packet in response to the coincidence signal. The multipoint video conference controlling system may comprise video and audio sequence number processing devices which add a sequence number to the composite packet and the mixed audio packet when the video packets and the audio packets have the sequence numbers. The multipoint video conference controlling system may comprise a sequence number producing and adding device which produces a sequence number in response to one of multiplexed video and audio packets from a video server and adds the sequence number to the composite packet and the mixed audio packet.

Title: Bayonet connector for surgical handpiece
Inventor: STODDARD ROBERT B
IPC: A61B17/32
Filed: 1995-09-11
Granted: 2000-06-06
Abstract: A connection of first and second members (11 and 12) wherein each has a body and a connecting end with an inner surface (17) so the second connecting end (19) has an outer surface (20) shaped for telescoping into the inner surface (17) of the first connecting end (16). A shoulder (21) is located on the second member (12) and a groove (22) is in the outer surface (20) of the second connecting end (19). A raised nub (23) on the inner surface (17) of the first connecting end (16) is radially inward to engage the groove (22). An elastomeric gasket (13) is positioned to bear against the shoulder (21) and be compressed between the first and second bodies. An engaging trough (24) in the groove (22) holds the first connecting end (16) against the shoulder (21) with the nub against the groove (22) by the compression force of the gasket (13). An indexing trough (25) in the groove (22) positioned along the groove (22) beyond the engaging trough (24) allows the nub to follow therethrough and slightly compress the gasket (13) thus giving the user a tactile indication that it has been rotated beyond the engaging trough (24). A method for fluid tight attachment of members (11 and 12) of a medical device has steps including the connection of the first and second members (11 and 12) with ends by telescoping the ends. Locating a groove (22) for operating the groove (22) as a cam (14) and locating a raised nub (23) of material on the inner surface (17) of the first connecting end (16) for positioning the raised nub (23) to engage the groove (22) for operating the raised nub (23) as a follower of the cam (14) are steps. Compressing a gasket (13) seal between the first connecting end (16) and the shoulder (21) while making the gasket (13) seal from an elastomeric material is a step. Positioning an engaging trough (24) in the groove (22) to hold the first and second connecting ends (19) against each other is a step. Positioning an indexing trough (25) in the groove (22) so when the nub is rotatably forced past the engaging trough (24) it will further compress the first end against the gasket (13) is a step.

IPC: B41J2/175
Filed: 1997-07-11
Granted: 2005-02-08
Abstract: A liquid discharging method for discharging liquid by displacing a movable member by means of air bubble created on the air bubble generating area, which the free end of the movable member faces, comprises the step of promoting the movement of the free end of the movable member by means for promoting the displacement of the free end thereof. With the adoption of this method, the pressure of the air bubble that acts upon the free end of the movable member enables the movable member to form an appropriate displacing configuration to lead the pressure exerted at the time of foaming and the development of the air bubble in the discharging direction efficiently. At the same time, the displacement of the movable member is performed smoothly, thus contributing to enhancing the durability of the movable member.
