Abstract: The nursing cover includes a fabric panel that has three portions.  The front portion is for draping over a nursing baby and over the front of a nursing mother.  The rear portion drapes over the shoulder and down the mother's back.  The central portion is made of a mesh-type fabric that has sufficient opacity to obscure the baby from the view of a bystander but sufficient openness of weave to permit ventilation for the baby.  Two areas of the outer side edge may be joined to provide additional privacy for the baby and the mother along the nursing side of the mother.   When not being used as a nursing cover, it can serve as a stroller cover, with complementary hook-and-loop-type fasteners being mated to form a sleeve that can be draped over a stroller brace.   In this embodiment the mesh-type fabric protects the baby from direct sunlight and provides privacy.

Title: Aerobic bioreactor for treating aqueous wastes at high organic and solids loadings
Inventor: PELLETIER DENIS
IPC: C02F3/22
Filed: 1997-11-18
Abstract: This invention generally relates to the treatment of wastewaters rich in organic content, either soluble or particulate, and is more specifically concerned with aerobic treatment wherein a new totally pneumatic bioreactor is capable of handling and treating aqueous wastes at high organic loadings and solids contents. Influent waste material treated in this compact bioreactor is submitted to a high degree of oxidation and the biological flocs are not exposed to high levels of shear stress. The flocs leaving the bioreactor after assimilation of carbon and essential growth nutrients settle in a passive clarifier to yield a partially to completely purified aqueous effluent and a sludge containing the biological solids. The latter can be handled using conventional methods for thickening or dewatering, stabilization or disposal. This highly efficient aerobic reactor prevents the formation and emission of malodorous gases. The present bioreactor can treat inflowing wastewaters containing from 0 to 6.5 % total suspended solids. Under a situation when 6.5 % suspended solids are to be treated a significant proportion of these solids should be biodegradable.

Title: Method and apparatus for automatically balancing a blower in a blown film extrusion line
Inventor: JOSEPH DANIEL R
IPC: B29C48/90
Filed: 1998-01-13
Abstract: The present invention is directed to a method and apparatus for startup of extruded film tubes. A controller member is utilized to provide control signals to a supply blower which supplies air to the extruded film tube in an amount corresponding to a supply control signal, and an exhaust blower which exhausts air from the extruded film tube in an amount corresponding to an exhaust control signal. The controller member executes program instructions which define at least one control routine for automatic and coordinated control of the supply blower and the exhaust blower during starting of the extruded film tube, by directing a series of supply control signals to the supply blower and exhaust control signals to the exhaust blower. When a valve is utilized to control the flow of air from the supply blower to the extruded film tube, the controller is also utilized to adjust the supply blower and the exhaust blower in order to optimize operation of the valve by placing the valve in a substantially linear operating range. Additionally, the controller member may be utilized to execute program instructions in order to implement a bubble break detection routine which utilizes software timers in combination with monitoring of a position signal in order to determine collapse or break of the extruded film tube.

Title: Chair locking mechanism
Inventor: DESNOYERS CHARLES
IPC: A47C3/03
Filed: 1998-04-07
Abstract: A locking mechanism for chairs such as gliding and rocking chairs comprises a toothed rack for connection to the chair seat with the rack oriented generally in the direction of movement of the chair seat relative to the base and the teeth extending along the rack and facing towards a pin that is carried in the base.
