Inventor: TRETHEWEY REGINALD
IPC: F16P3/14
Filed: 2002-10-03
Abstract: Material introduced into hopper (1) is compressed by two sets of fingers (3) staggered in length, to form a bale in a chamber beneath hopper (1). For safety the baler includes passive infrared (PIR) detector (14) having shield (15) so that it receives radiation from hopper (1) only. Introduced material will have no effect, as detector (14) requires both the heat and motion of a worker's body part for activation. On downward movement, fingers (3) are locked in an extended orientation so as to compress material whereas on upward movement they are free to pivot, retracting from the sides of hopper (1).  Valving in hydraulic resistance struts (11) assists this pivoting of fingers (3).

Title: Combined tape measure and marking device
Inventor: GUEST JOHN ROBERT
IPC: G01B3/10
Filed: 2004-05-31
Abstract: Improvements are provided herein in a tape measure of the type including a housing having a first wall, a second wall and an end wall in which a transverse slit is provided, a spool rotatably supported in the housing on which an elongate d tape having a plurality of measured graduations thereon is wound, the tape extending through the transverse slit, releasable means to retain the tape in any selected extended position when the spool is rotated in a first direction to extend t he tape through the slot, means for rotating the spool in an opposite direction to retract the tape into the housing, and a stop on a free end of the tape to prevent the tape from being completely retracted into the housing. Such improvements include a marking arm on a selected wall, the marking arm having a proximal end and a distal end. The distal end of the arm includes a replaceable marking stylus. One improvement includes a particular end-to-end combination of the replaceable marking styl us with the distal end of the marking arm. Another improvement includes a first stop member which is provided on that selected wall adjacent to the marking arm. The proximal end of the marking arm includes a limit stop member. The first stop member is configured to cooperate with an edge of the marking arm to limit rotation of the marking arm in a counterclockwise direction to an inoperativ e position. The first stop member and the limit stop member are configured to cooperate to limit rotation of the marking arm in a clockwise direction to a n operative position. Thus, when the marking arm is in its operative position, the replaceable marking stylus is transversely aligned with a desired graduation on the tape, thereby permitting a mark to be manually made on an article or on a material that is transverse to the desired graduation.

Title: Methods and systems for managing and collecting impulse pay-per-view (ippv) data in smart card enabled television terminals
Inventor: KUCZYNSKI-BROWN JEFFREY D
IPC: H04N7/173
Filed: 2003-01-03
Abstract: Methods and apparatus for managing and collecting impulse pay-per-view (IPPV) data in smart card enabled digital television terminals are provided. A  headend controller sends security information to the terminal for use by the smart card. Authentication data based on the security information is computed by the smart card. The controller polls the terminal to retrieve the authentication data and current IPPV data from the smart card. Current IPPV  data is validated by the controller based on the authentication data. Upon validation of the current IPPV data, updated IPPV data is sent from the controller to the smart card via the terminal. The present invention also enables a purchase report back message to be constructed at the terminal at the time of an initial IPPV purchase, rather than at the time of the poll from the controller. The purchase report back message may be updated at the time of each subsequent IPPV purchase after the initial purchase.

Title: Suction motor for vacuum cleaner
Inventor: POUPORE TIMOTHY
IPC: A47L5/22
Filed: 2003-03-12
Abstract: A cleaner (1) has a DC brushless motor (15) with stator (203) and rotor (212). Stator is mounted on a shaft and rotor is mounted inside and to a tubular body (207) about stator (203). Impeller (17) is mounted to and outside tubular body (207). The motor (15) and impeller (17) are mounted in a housing having an intake (17) and an exhaust (9). Operation of the motor and rotation of the impeller causes a partial vacuum at the intake (7) to draw air. The air is exhausted through the exhaust (9). A filter (61) prevents particles from entering the motor (15). Particles are collected in a receptacle (5) prior to the filter (61). The impeller (17) may be a squirrel cage fan, bladed fan, or centrifugal fan. A secondary exhaust (11) expels particles from the filter (61) and/or receptacle (5) by rotation of the impeller (17) in an opposite direction or by the use of a secondary DC motor and impeller. The housing (2) can fit in a cavity between conventional wall studs.

Title: Kit for providing an automatic steering system
Inventor: PALMER RON
IPC: G05D1/02
Filed: 2004-09-21
Abstract: An automatic steering kit comprises a microprocessor connectable to a global positioning system and operative to compare the sensed location with a desired vehicle path. A controlled pressure reducing valve provides hydraulic fluid at a reduced pressure less than the vehicle hydraulic supply pressure. Low pressure conduits are connected to the reducing valve and steering conduits. In response to an automatic steering signal generated by the microprocessor, the reducing valve directs hydraulic fluid at the reduced pressure through the low pressure conduits to extend and retract the hydraulic steering cylinder to automatically steer the vehicle. The difference between the reduced pressure and the supply pressure is such that turning the steering wheel will steer the vehicle against the automatic steering force applied through the low pressure conduits. A gyroscope is added to provide improved vehicle steering.

Abstract: Toutes les lignées cellulaires de myélome multiple qui ont été examinées présentent une kinase I.kappa.B (IKK) constitutivement active, une phosphorylation d'I.kappa.B.alpha. et une NF-.kappa.B constitutivement active. La curcumine, un agent chimiopréventif, permet de supprimer la phosphorylation d'I.kappa.B.alpha. constitutive en inhibant l'activité d'IKK et en régulant négativement NF-.kappa.B. La curcumine régule aussi négativement l'expression de produits géniques régulés par NF-.kappa.B tels que I.kappa.B.alpha., Bcl-2, Bcl-x<SB>L</SB>, la cycline D1 et l'interleukine 6. Par conséquent, la curcumine permet de supprimer la prolifération de cellules de myélome multiple et d'arrêter les cellules à la phase G1/S du cycle cellulaire. La curcumine induit également l'apoptose et une chimiosensibilité à la vincristine. De manière générale, les résultats présentés fournissent une base moléculaire pour traiter des patients atteints de myélome multiple à l'aide de cet agent pharmacologiquement sûr.
