Title: Cap for a well casing, and method to retrofit a well casing with a cap
Inventor: ACHESON BRIAN C
IPC: E21B33/00
Filed: 2001-07-30
Abstract: This invention is a cap for protecting wells from ground surface liquids getting into a well through the top. The cap encompasses the lid and the top portion of the well casing. The cap has a top, a sidewall and an access port. The top is coupled to a sidewall to define a space to accept a lid and well casing. In preferred embodiments of the invention, the access port has either a tuba and boss or a neck and adaptor. The boss surrounds an opening in the top and receives a proximal end of the tube whereas the neck surrounds the opening in the top and the adaptor is received within the neck. The cover is disposed on the tube or neck at an open end distal to the top to cover the opening. In both embodiments, there is at least one hole in the access port. The cap prevents surface liquid from entering into the well though the top.

Title: Shock-absorbing tool handle
Inventor: SHAUD RONALD J
IPC: E01H5/02
Filed: 1999-04-08
Abstract: A shock-absorbing telescoping tool handle (2) is disclosed having a larger diameter proximal portion (4) and a smaller diameter distal portion (6). An internal spring (14) in the handle portions is compressed when the handle portions telescope towards each other upon shock being applied to the tool handle. Guide mechanisms (26, 28) in the handle portions limit the extend of sliding motion between the handle portions and prevent relative motion of the handle portions. One or more wipers (40) in the handle portion wipes away any snow, water or debris on the distal portion which could potentially enter the spring area. The spring may be located within the proximal portion or the distal portion of the tool handle.

Title: Linear motor
Inventor: DUNCAN GERALD DAVID
IPC: H02K33/16
Filed: 2000-06-21
Abstract: The present invention provides an improved design of linear motor as well as  an improved control strategy. The design allows for a shorted stator, where the armature magnets are controlled to reciprocate to a greater maximum displacement than for a equivalent conventional linear motor. The control strategy is such that a minimum of external sensors are required. The linear  motor is driven at its resonant frequency ensuring optionally efficient operation. A determination of the maximum current is made based on a relationship with the resonant frequency and the evaporating temperature/pressure of the vapour entering the compressor. The current is then limited to control the maximum displacement to avoid damage.

Abstract: The present invention is a novel and improved method and system for communicating a frame of information according to a discontinuous transmit format. In particular, the present invention describes a method of transmitting eighth rate speech or data frames employing transmit gating and  energy scaling which simultaneously reduces the battery usage of a variable rate wireless communication device (50), increases the capacity of the rever se link and provides reliable communication of the eighth rate frames. In the present invention, four methods are presented for transmitting an eighth rat e data frame in which half of the frame is gated out and the remaining data is  transmitted at nominal transmission energy to accomplish the aforementioned goals. In addition, a power control system identifies forward link power control bits that have been gated out by the remote station (50) and inhibit s adjustment of the transmission energy in response to that identification.</S DOAB>

Title: Method and device for managing a device for intermediately storing flat objects
Inventor: STAUBER HANS ULRICH
IPC: B65H29/00
Filed: 2000-07-20
Abstract: For managing an installation for intermediate storage of flat articles e.g. in rolls, in particular of printed products, at last one positioning device (5) and at least one orienting device (6) are provided. The installation comprises a plurality of winding stations (1), a plurality of mobile roll stands (2) and a plurality of storage spaces (2.1, 2.2) for roll stands. The storage spaces (2.1, 2.2) are situated on a plurality of parallel primary transport paths. The primary transport paths (3) intersect at least one secondary transport path (4.1, 4.2). The entrances of the winding stations (1) are arranged along a secondary transport path (4) and are aligned with primary transport paths (3). For retrieving roll stands (2) from storage spaces (2.1, 2.2) and winding stations (1) by pulling and positioning them by pushing, the positioning device (5) is actively displaceable along primary transport paths (3). The orienting device (6) serves for receiving loaded or empty positioning devices (5) in order to re-orient them for subsequent transport steps along primary transport paths (3), in order to displace them along secondary transport paths (4.1, 4.2) and if so required in order to raise or lower them to further levels with further storage spaces (2.1, 2.2) and primary and secondary transport paths (3, 4). The method and the device are applicable in an analogous manner for managing installations for intermediate storage of rolls of flat articles being handled without roll stands but e.g.  on pallets, or of other storage formations of flat articles being handled with other, suitable supporting elements.

Title: Method and communications system for handling a packet service
Inventor: HAHN WOLFGANG
IPC: H04W88/16
Filed: 2000-07-13
Abstract: The invention relates to a method and a communications system for handling a packet service with a packet-based core network (CNW) and an access network (ANW).  According to the subject-matter of the invention, the control node (EN) which is arranged at an interface between the core network (CNW) and access network (ANW) can control the transmission of multimedia data in the packet data and integrate it into the data transmission from and to the mobile communications device (MS) via the radio interface of the access network. The advantage of the invention is that the control node can actively intervene in the signaling of the transmission of the multimedia data as packet data, i.e. this signaling no longer needs to be carried out transparently with respect to the mobile communications device. A further advantage is that as a result of the integration of the supervision of the multimedia data transmission, the data streams can be better adapted to the radio resources and/or to the requirements of the mobile communications device.

Patent CA-2392324-A1 (CA)
Inventor: MICHEL EDOUARD
IPC: B60C9/02
Filed: 2002-07-03
Abstract: The invention relates to methods for improving vehicle steering performance and robustness of that performance through control of non-uniformities in the Vehicle's tires, wheels and tire/wheel assemblies as a way to overcome the tendency of the steering systems in certain vehicle types to undergo "steering performance loss." While minimizing lateral force variations (e.g., couple imbalance), a controlled amount of radial and/or tangential force variation is induced in one or more tire/wheel assemblies by means of mass non-uniformity, dimensional non-uniformity, and/or stiffness non-uniformity. For stiffness non-uniformity, the preferred method comprises imparting a controlled amount of stiffness non-uniformity to the tire in at least one of the tire/wheel assemblies, followed by statically and dynamically balancing all of the vehicle's tire/wheel assemblies. The stiffness non-uniformity comprises one or more sectors of the tire having a different (less or preferably more) stiffness than the remainder of the tire. All tire non-uniformities imparted according to the invention are preferably distributed meridionally symmetrically about the equatorial plane of the tire, so as to induce tangential and/or radial force variations but not lateral force variations. Beneficial tangential and/or radial force variations will result from the operation of such a tire, ever if the tire/wheel assembly is balanced by weights added to the wheel. The stiffness non-uniformity is preferably imparted in the tire by means of one or more heavy splices, and/or extra pieces of fabric applied to the carcass or tread;  and/or sectors of tire components having different stiffness. Synergistic beneficial effects result from combinations of the various forms of beneficial mass, stiffness, and dimensional non-uniformity.
