Abstract: A particulate material dispensing system suitable for metering seed for individual rows of a seed sowing drill. The seed sowing drill having a container which acts as a seed hopper. Positioned beneath the container is a metering device. Below the metering device are a number of tubes which are seed outlets to which the metering device feeds the seed it receives from the container. A peripheral guide forms part of the meterin g device. The peripheral guide is a disc of material that defines an aperture. On the inne r walls of the guide is a seed track and an outlet. There are a plurality of seed track/outlet combinations, one for each of the outlets. A vertical-axis rotor fits within the aperture of the guide. The rotor rotating within the aperture causes seed falling from t he container into the guide to be dragged down and around the inside walls of the guide. The seeds are guided by a seed track to a guide outlet and into the appropriate seed outle t. At the base of the seed track is a flange. The flange enables a column of seed to build up within the seed track providing some independence of the availability of the seed to th e rotor from the container. A method of dispensing particulate material is also disclosed .

Title: Method and apparatus for providing enhanced pay per view in a video server
Inventor: OZDEN BANU
IPC: H04N7/173
Filed: 1997-01-31
Granted: 2001-03-20
Abstract: A method and an 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 is defined by a computation time and a period. To schedule the group of tasks, the present invention divides the tasks into two groups according to whether they may be scheduled on less than one processor. The present invention schedules each group separately. For the group of tasks scheduleable on less than one processor, the present invention conducts a first determination of scheduleability. If the first determination of scheduleability deems the group of tasks not scheduleable, then the present invention conducts a second determination of scheduleability. If the second determination of scheduleability also deems the group of tasks not scheduleable, then the present invention recursively partitions the 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.

Abstract: A calender for satining paper through roll gap formed between a heated hard roll and a soft roller having an elastic covering.  Overheating of an edge region of the covering, i.e., the portion not covered by the paper to be satined, may be prevented by utilizing continuous insulation belts.

Title: Capacitive absolute pressure sensor and method
Inventor: KO WEN H
IPC: H01C7/00
Filed: 1995-11-09
Granted: 2002-10-15
Abstract: A capacitive absolute pressure sensor (10) includes a substrate (14) having an electrode (24) deposited thereon and a diaphragm assembly (12) disposed on the substrate (14). As pressure increases, the diaphragm (16) deflects, touches the electrode (24) (in the touch mode), and changes the capacitance of the sensor (10). The changed capacitance is sensed to thus sense pressure changes.  A burried feedthrough is used to sense the change in a capacitance in a chamber (34) under the diaphragm (16) and thus determine the pressure sensed.  A vacuum in the chamber (34) is maintained by proper selection of a thickness of a sensing electrode and an insulating layer (32), exposition thereof to a thermal cycle, and the hermetic bonding of the diaphragm assembly (12) to the substrate (14).

Abstract: A reduced shear reclining seat back assembly employs a single rotary actuator for reclining a seat back relative to a seat portion and controlling movement of a seat back member in response to the reclining operation. A rotary actuator includes a first arm pivotally secured to the seat back, preferably through a link which is connected to the movable back member. A second arm of the actuator is pivotally secured to the seat portion. As the angle between the first and second arms decreases, the seat back reclines and the movable seat back member is drawn toward a seat pivot axis. Likewise, when the angle between the arms increases, the seat back is brought to an upright position and the movable seat member travels away from the seat pivot axis.

IPC: C23C14/34
Filed: 1997-09-02
Granted: 2005-07-12
Abstract: A method is described for depositing a complex optical multilayer coating on a substrate. The coating consists of multiple layers of at least two material types. The layers are sequentially deposited in a deposition chamber by reactive deposition;  preferably sputtering, and the thickness of the deposited layers is determined one or more times during the layer deposition by taking optical measurements of the deposited layer and fitting theoretical values derived from a model of the deposited layers to the corresponding actual values obtained from said measurements. A process variable is continually controlled to ensure homogeneity of the deposited layers so that a valid thickness determination can be made from said theoretical model.

Title: Brake shoe assembly formed using hot staking method
Inventor: KOSCIELSKI LARRY F
IPC: F16D65/08
Filed: 1997-09-15
Granted: 2006-09-12
Abstract: A brake shoe assembly is formed by precision stamping a net shaped web blank out of steel forming a series of tabs projecting outward therefrom, stamping a corresponding table member provided with tab receiving apertures, and bending the table member into a semi-cylindrical segment. The web blank and the table are assembled causing the web tabs and table apertures to be interlocked securely locating the parts temporarily together. The cooperating tabs and projections are then permanently joined together using a hot staking process which quickly heats, radially deforms and self quenches the tab to metallurgically strength the joint.

Granted: 2001-02-27
Abstract: A vertical cavity surface emitting laser comprises a resonant cavity (2) formed between a distributed Bragg reflector formed of semiconductor material (3) and an overlying distributed Bragg reflector (4) formed of dielectric material. The resonant cavity contains a layer (8) of laser active material sandwiched between spacer layers (9, 10), and a blocking layer (16, 19) which confines an energising electric current to flow through the cavity between a metallic contact layer (13) on the underside of the Bragg reflector (4) and a contact (17). In order to support a preselected resonant mode, a series of concentric rings (18) is formed in the blocking layer (16, 19), surrounding the resonant cavity (2) so as to provide a Bragg structure which reflects light from the cavity with a phase characteristic that supports the preselected transverse resonant mode.
