Title: Vacuum cleaner head
Inventor: SCHUPP ANDREAS
IPC: A47L9/06
Filed: 1997-02-05
Abstract: A vacuum cleaner head, for attachment directly to a vacuum cleaner body having a central longitudinal axis, has exposed bristles with remote ends on a plane off-set by about 70° to the central axis. The bristles 14 and 15 extend along opposing sides of a lower surface of the head in strips at either side of a channel 18 through which dust and debris gathered up by the bristles passes into the vacuum body. The off-set plane means that when the body is held directly or by a handle, a natural comfortable sweeping action, with the handle axis at about 20° to the vertical, keeps both strips of bristle in contact with the swept surface.

Abstract: The essence of the proposed method resides in  that assumed  as  the  datum point of measurement of the well azimuth  is  an  azimuthally  stabilized  housing  of  a down-the-hole  instrument  (1)  (inclinometer),  and the magnitude of the azimuth is determined by measuring  the angle  of  rotation  of the housing of the down-the-hole instrument  (1)  round  its  longitudinal  axis,   which rotation occurs in response to an azimuthal deviation of the longitudinal axis of a  well  (5).  According  to  a first embodiment of the proposed device,  it comprises a plurality of spring-loaded arcuate elements (3)  secured on an  external  surface  (2)  of  the  housing  of the down-the-hole instrument (1) so  as  to  form  at  least three  rows,  each  row  consisting  of  at  least three elements (3),  each of the latter establishing, together with an internal surface (4) of the well (5),  a contact spot (6) whose portion having  a  greater  size  (h)  is arranged  lengthwise  the  longitudinal axis of the well (5).  According to a second embodiment of  the  proposed device,  it comprises a rod (29) arranged coaxially with a housing (30) of a down-the-hole  instrument  (31)  and hold  in  position thereto so as to ensure against their mutual rotation,  and a plurality of  the  spring-loaded arcuate  elements  (3)  secured  on  the  external  side surface of the rod (29) similarly to their securing  to the  housing  of the down-the-hole instrument (1) in the first embodiment of the device.

Filed: 1997-03-05
Abstract: A method and apparatus for transferring a load to and from a load supporting platform having a first end pivotally coupled toward the first end of a main frame with a support surface for supporting the platform in a substantially level position. The platform is pivotally raisable from the support surface of the main frame to a raised position for discharging and accepting a load either manually or by an actuatable member. A damping member interconnects the platform and the main frame wherein the damping member progressively increases resistance on the load bearing platform as the platform moves from the raised position toward the support surface of the main frame to reduce any impact on the load. The platform includes a lower frame and a cover biased away from the lower frame by a plurality of spring members wherein the cover is movable toward the lower frame by a load disposed on a support surface of the cover to actuate a load sensor, which indicates the presence of the load. A first pair of motor driven wheels is coupled to the first end of the main frame to drive the apparatus along an operating surface, and a second pair of wheels is coupled to a opposing sides of a pivoting member to compensate for unevenness in the operating surface.

Inventor: STEPHENS SCOTT A
IPC: H04B7/195
Filed: 1997-04-16
Abstract: A power control method and apparatus are provided for a satellite based telecommunications system.  The system includes a power control subsystem which is operative with systems operations center for distributing available satellite power between earth stations.   Each earth station includes a baseband manager which subdivides the available satellite power between subband beams emitted from the satellite.   The earth station further includes beam processors which manage the power allocated to each subband within an associated beam in order to maintain a desired signal quality in a forward link between the satellite and user terminals within the associated subbands.  The beam processors communicate with modems,  each of which  is  assigned to a particular user terminal.  Each modem controls the satellites transmission power in the forward link to the user terminals to maintain a desired signal-to-noise ratio at the user terminal receiver.  The signal-to-noise ratio is determined by the corresponding beam processor.          The subsystem further provides a dynamic power control loop between user terminals in the forward and return links to maintain a desired signal quality.  The subsystem automatically controls the satellite output power level to ensure proper power emission by a satellite in connection with feeder links from multiple earth stations.

Title: Ball and socket closure
Inventor: KIRK KARL DALLAS III
IPC: A61B5/154
Filed: 1997-07-22
Abstract: A closure for scaling the open end of body fluid collection, transport or storage containers or tubes. The closure includes a ball and socket arrangement, wherein the ball rotates within the socket to align a passageway through the ball with the opening in the tube. To close the closure, a tab or protrusion extending from the ball is pushed to rotate the ball and orient the passageway perpendicular to the opening of the tube.

Title: Method and apparatus for monitoring liquid flow through an enclosed stream
Inventor: MCPHERSON W ROGER
IPC: B01D35/143
Filed: 1998-03-17
Abstract: A liquid flow meter is designed to monitor the flow of a liquid through an enclosed stream such as through the tubes or internal passageways of a device such as a filtration system. The liquid flow meter includes an axial-flow magnetic turbine and a detector such as a reed switch that monitors turbine rotation by counting pulses. The counted pulses are then used to determine the aggregate volume of liquid that has flowed through the flow meter. When the liquid flow meter is used in a domestic potable water filtration system or in a similar application, the counted pulses can also be used in conjunction with a timer to determine liquid flow rate as well as theremaining useful life of a filter cartridge of the filtration system and/or of the remaining volumetric filtration capacity of the filter cartridge. The liquid flow meter exhibits high linearity or consistency of flow measurement over a wide range of liquid flow rates -- even at very low pressures and low flow rates. The liquid flow meter also exhibits a very small pressure drop thereacross, requires minimal electrical power for operation, and is also compact and versatile so as to be usable with minimalmodification to existing filter assembly designs.
