Abstract: An implantable infusion device includes of a disc-shaped housing that is made from a biocompatible material. The housing contains a reservoir for holding a volume of infusion medium, such as a medication to be administered to the patient. A reservoirs for an implantable infusion devices may be configured to reduce the thickness requirements of the device, without compromising volume capacity of the device. In addition, such a reservoir configuration can allow multiple dispensing and fill or re-fill operations, with reduced risk of damage to the reservoir components. The reservoir defines a chamber that contains at least one flexible diaphragm. Each diaphragm has an outer peripheral edge within the chamber, a convolution adjacent the peripheral edge and a generally smooth central portion that is free to flex within the chamber, wherein the convolution enhances the flexibility of the diaphragm. A ring is provided in alignment with the peripheral edge of each diaphragm.

Abstract: A hydraulically operated fan for a cooling system in an automotive vehicle. Two hydraulic motors drive a common fan shaft. A control system provides means to bypass flow in parallel with both motors or direct flow to both or one of the motors dependent on inlet flow and cooling signal conditions.

Abstract: A system for quickly and easily creating a structured document is disclosed. A structured document may be configured to be a document adhering to a set of pre-defined rules providing order to the content of the document. By providing sets of rules, a limited set of structured document templates may be provided while still retaining flexibility of creation for the user. A Document Type Definition (“DTD”) may be configured to provide this set of pre-defined rules for a selected template. The Document Authoring System (“DAS”) may be configured to receive a user selection of a template, the template selection being based on the type of structured document the user intends to generate. The DAS, in response to a selected template, presents the user with a graphical user interface with which to quickly and easily enter information.

Abstract: A step stool includes a foldable frame having a front leg and a rear leg movable relative to the front leg and a carrying handle supported for pivotable movement on one of the legs about a pivot axis. A retainer member is coupled to the handle to move with the handle about the pivot axis to lock the front leg to the rear leg.

Abstract: A step stool includes a frame including a front leg and a rear leg movable relative to the front leg and a leg lock coupled to the frame and arranged to retain the rear leg in a fixed position relative to the front leg upon movement of the rear leg to an opened use position lying at an angle to the front leg. The leg lock includes a button receiver coupled to the front leg and a button supported for movement on the rear leg from a released position arranged to disengage the button receiver to allow relative movement of the front and rear legs and a locked position engaged to the button receiver to retain the rear leg in the fixed position.

Abstract: A foldable step steel (10) includes a frame 12 having front and rear legs (14, 16) and top, middle, and bottom steps (34, 36, 38). A central step link (40) is coupled to the rear portion of each step (34, 36, 38) to support the steps when step stool (10) is unfolded and to control pivoting movement of the steps relative to front leg (14) during folding of step stool (10). A releasable latch (22) is coupled to a rear portion of top step (34) and configured to engage an upper cross strut (180) included in rear leg (16) to retain step stool (10) in an unfolded use position.

Abstract: A step stool includes a frame including a front leg and a rear leg coupled to the front leg for movement relative to the front leg, a handle supported for pivotable movement on the front leg about a pivot axis, and a retainer coupled to the handle to move therewith about the pivot axis and arranged to trap a portion of the rear leg between the handle and the retainer upon movement of the handle to a predetermined position relative to the rear leg to lock the front leg to the rear leg.

Abstract: A method for assembling a step stool includes the step of providing a frame including a front leg and a rear leg coupled to the front leg for pivotable movement between an opened use position and a collapsed storage position, a step coupled to the front leg for pivotable movement between a horizontal use position and a storage position, and a link including a body, a pivot coupled to the body and the step, and a connector coupled to the body. The method further includes the step of snapping the connector into engagement with the rear leg for movement of the rear leg from its opened use position to its closed storage position in response to movement of the step from its horizontal use position to its storage position.

Abstract: A child car seat for a vehicle. The vehicle has a shoulder belt, and the shoulder belt includes a webbing. The child car seat includes a structural seat back and a vehicle-shoulder-belt-receiving first hook attached to the seat back. The first hook substantially encloses a first through slot, wherein the first through slot extends from front to back. The first hook includes two hook members which are spaced apart from each other by a first gap which is larger than the thickness of the webbing. The webbing is engageable in the first through slot.

Abstract: A step stool includes a foldable frame having a front leg and a rear leg movable relative to the front leg and a carrying handle supported for pivotable movement on one of the legs about a pivot axis. A retainer member is coupled to the handle to move with the handle about the pivot axis to lock the front leg to the rear leg.

Abstract: Wood pulp is bleached using hydrogen peroxide as the oxidative bleaching agent in the presence of magnesium hydroxide or magnesium oxide. The bleaching process is carried out in the presence of magnesium hydroxide as the predominant, and preferably essential, source of alkali. The process optionally includes transition metal chelants, such as DTPA or EDTA in the bleaching slurry. The process eliminates the need for added caustic and silicate in such systems and can be carried out at or near neutral pH of 5.0 to 8.5.
