Disclosed is a male undergarment that has an expandable pouch. The pouch expands as needed depending on the male's genitalia. The pouch has a horizontal elastic band one and two-third inches below the garment's waistband which enables the pouch to adjust as needed. This horizontal elastic band is to be a half an inch long and one cm width depending on the size of the pouch. This pouch also has a four technique fold of material to increase comfort in the pouch. The two components combined creates a pouch that expands to the male's need.

The catalyst solution used in a hydroformylation process is prepared for storage by first reducing its acid concentration and/or water content, and then storing the solution under a blanket of syngas and/or an inert gas. Alternatively, or in addition to, the catalyst solution can be stored with an aqueous buffer comprising materials that will neutralize and/or absorb the acid species within the catalyst solution.

A bag with integral legs. The bag includes a base with sidewalls forming a main compartment with an interior volume. A pair of legs is attached to a lower side of the base and configured to pivot between a stowed position and an extended position. In the extended position, the bag is supported off of a ground surface at a desired height. Additionally, the bag includes a tray configured to extend outwardly from the bag, providing a convenient work surface for a user. The bag may further include a lower pocket adapted to fully enclose the pair of legs therein when the pair of legs is in the stowed position. Some embodiments include a locking hinge to lock each of the pair of legs either in a stowed or in an extended position, offering additional stability to the bag when in an elevated position.

摘要:
The extraction process for removing metal salts from an organic hydroformylation reaction fluid (“HRF”) prior to returning the HRF to a reaction zone of a hydroformylation process, the extraction process comprising the step of contacting the HRF with an aqueous buffer solution, is improved by contacting the HRF with water in addition to that present in the aqueous buffer solution, i.e., with added water.

Methods and systems for processing coverings such as leather hides and fabrics are provided. A system can include a worktable having a surface on which a covering is placeable. An imaging device can be positionable relative to the worktable. The imaging device can be configured to obtain an image of the covering on the surface of the worktable. A projector can be positionable relative to worktable. The projector can be configured to project an image onto the surface of the worktable and the covering on the surface of the worktable. A controller can be in communication with the imaging device and projector. The controller can be configured to correct images taken by the imaging device. The controller can also be configured to correct the images projected onto the surface of the worktable and the covering thereon. The controller can be configured to permit the showing of virtual markings on the covering placed on the surface of the worktable through an image projected thereon by the projector. The covering can then be marked or cut along the virtual markings.

A catalyst composition for the polymerization of propylene is provided. The catalyst composition includes one or N more Ziegler-Natta procatalyst compositions having one or more transition metal compounds and an internal electron donor, one or more aluminum containing cocatalysts, and a selectivity control agent (SCA), The SCA is a mixture of an activity limiting agent (ALA) and selectivity determining agent (SDA) such as a non-silane composition. The present catalyst composition is silane-tree, has high catalyst activity and high stereoselectivity, and is self-extinguishing.

A catalyst composition for the polymerization of propylene is provided. The catalyst composition includes one or more Ziegler-Natta procatalyst compositions having one or more transition metal compounds and an internal electron donor, one or more aluminum containing cocatalysts, and an external electron donor. The internal electron donor is a bidentate compound excluding plithalates. Suitable bidentale compounds include diethers, succinates, dialkoxybenzenes and diol esters. The external electron donor is a mixture of an activity limiting agent and selectivity determining agent. The present catalyst composition has high catalyst activity and high stereoselectivity, and is self-extinguishing.
