Title: Gas mixing and dispersement in pumps for pumping molten metal
Inventor: THUT BRUNO H
IPC: F04D29/18
Filed: 2005-12-02
Abstract: A pump mixes gas and molten metal and pumps molten metal. A base of the pump includes an inlet and an outlet, a mixing impeller chamber adapted to mix gas and molten metal and a pumping impeller chamber adapted to pump molten metal. First and second impeller members supported by a shaft are adapted to rotate in the mixing and pumping chambers, respectively. The impeller members may be integrally formed components of a single impeller or separate impellers supported on one or more shafts. A gas passageway extends from a gas source in proximity to the mixing chamber in the base. A gas dispersement pump for molten metal includes a base including an impeller chamber, an inlet and an outlet. An impeller is mounted to a shaft and adapted to be rotated in the impeller chamber. A gas passageway extends from a gas source to a gas outlet in proximity to the impeller chamber. A gas dispersement member composed of porous refractory material is adapted to disperse gas supplied from the gas passageway. In a gas dispersement and gas/molten metal mixing pump, the gas dispersement member disperses the gas stream, which enters the mixing chamber where the gas is further mixed with the molten metal. Molten metal is also pumped by rotation of an impeller in the pumping chamber. A stream of a gas and molten metal mixture is discharged from the lower mixing chamber while a stream of molten metal is discharged from the pumping chamber.

Title: Multiple-use cover with see through carrying article
Inventor: TOOMBS TIMOTHY B
IPC: A45C13/00
Filed: 2005-12-02
Abstract: A multiple-use cover with an easy access opening used to cover a see through carrying article such as a backpack, tote bag or diaper bag. The easy access opening on multiple-use cover allows user to gain access to the inside of the carrying article and its pockets through an opening in the multiple-use cover. The easy access opening consists of a zipper or flap opening on multiple-use cover used to gain access to see through carrying article without having to remove the cover. The multiple-use cover is useful when the user is carrying a see through carrying article such as backpack or tote bag and wants to protect the privacy of what they are carrying thus enhancing their own personal safety during their commute. The cover allows a user to spend less time getting through check points in a secure environment by allowing the user to remove the cover for quick examination of the see through carrying article. The multiple-use cover pocket(s) can be made see through with a see through lining which would allow a screener to quickly examine them. The shape of the multiple-use cover can be made to fit any type of see through carrying article with or without wheels and provides great utility in that it allows the user to utilize the shoulder strap(s) and handgrip found on most carrying articles such as backpacks or tote bags. The multiple-use cover can be made to be worn on either side or inside out. When the cover is no longer needed it can be converted into a pouch and stored away inside carrying article or worn as a fanny pack or bag around waist or shoulder.

Patent CA-2536348-A1 (CA)
Inventor: LOVELESS CALVIN J
IPC: A61J7/04
Filed: 2006-02-13
Abstract: An automatic prescription pill dispensing unit uses a cartridge in which prescription drugs are pre-loaded, preferably by a pharmacist, according to the user's medication regimen. This tamper-proof cartridge can only be unlocked by a pharmacist using a specially designed loading dock, or by inserting the cartridge into the user's dispensing unit.  This cartridge approach not only simplifies the loading of the dispensing unit but, more importantly, removes from the caregiver the responsibility of having to handle prescription drugs.  The cartridge approach also reduces the footprint size of the original dispensing unit by about 50%. The cartridges can dispense pills up to four times a day for 7 days, and the unit can hold pills from two cartridges, giving 14 days of medication.

Inventor: ERLANDER MARK G
IPC: G16H50/30
Filed: 2004-09-17
Abstract: Methods and compositions are provided for the identification of expression signatures in ER+ breast cancer cases, where the signatures correlate with responsiveness, or lack thereof, to treatment with tamoxifen or another antiestrogen agent against breast cancer. The signature profiles are identified based upon sampling of reference breast tissue samples from independent cases of breast cancer and provide a reliable set of molecular criteria for predicting the efficacy of treating a subject with breast cancer with tamoxifen or another antiestrogen agent against breast cancer. Additional methods and compositions are provided for predicting responsiveness to tamoxifen or another antiestrogen agent against breast cancer in cases of breast cancer by use of multiple biomarkers. Two biomarkers display increased expression correlated with tamoxifen response while two other biomarkers display decreased expression correlated with tamoxifen response.

IPC: E21B37/02
Filed: 2004-11-23
Abstract: A downhole swivel joint assembly (18) comprised an upper component (18a) and a lower component (18b). The components may assume either of two stable positions relative to each other, namely an unactivated configuration (as shown in Figure 2) in which the components are rotationally fast with each other by virtue of the inter-engagement of splines (54) of the lower component with splines (56) of the upper component and an activated configuration in which the respective splines are disengaged so that the upper and lower components can rotate relative to each other. In the activated configuration the upper component is supported relative to the lower component on a ball bearing pack (42). Movement of the components between the activated and unactivated configurations is controlled by a resiliently deformable latch member (84) which is C-shaped in transverse cross-section. The latch member has an internal profile which co-operates with an external profile provided on the upper component mandrel (34) to allow the upper and lower components to snap between the activated and unactivated configurations.

Abstract: A hammer drill bit chuck attachment comprises a main shaft having a forward drill chuck end portion and a rearward shank portion, and defining a longitudinal axis. An impact member is mounted in fixed relation on the main shaft for rotation therewith.  An actuator mechanism is mounted on the main shaft for free rotation of the main shaft with respect to the actuator mechanism and for longitudinal sliding movement of the actuator mechanism along the main shaft between a forwardly displaced position and a rearwardly displaced position. At least one impact portion is disposed on one of the impact member and the actuator mechanism.    At least one roller member is rotationally mounted on the other of the impact member and the actuator mechanism. Rotation of the main shaft and impact member about the longitudinal axis when the actuator mechanism is in force transmitting engagement with the impact member, causes the actuator mechanism to move in a reciprocating motion between the forwardly displaced position and the rearwardly displaced position, and transmits impact forces forwardly along the longitudinal axis to the main shaft.
