Mineral slurry drying method and system
Patent No. 9,759,486
The present invention provides methods and systems for reducing moisture in mineral slurries, particularly mineral slurries containing minerals of small particle diameter, using a granular drying material. The invention also relates to novel mineral products and intermediates useful in connection with the process. The method and system reduced moisture by contacting the mineral slurry with the granular drying material. The granular drying material is selected to be readily separated from the dried minerals using a size separation technique such as a sieve screen. The granular drying material is the regenerated, preferably using a process involving heat exchange and cross-flow air. The granular drying material is preferably capable of regeneration and recycling in a continuous process with minimal attrition.

Process for making polyether alcohols having oxyethylene units by polymerization of ethylene carbonate in the presence of double metal cyanide catalysts
Patent No. 9,758,619
Ethylene carbonate is polymerized by itself or together with another cyclic monomer such as 1,2-propylene oxide in the presence of a double metal cyanide catalyst. Most of the ethylene carbonate adds to the chain to form a terminal carbonate group, which decarboxylates to produce a hydroxyethyl group at the end of the polymer chain. The polymerization of more ethylene carbonate onto the chain end results in the formation of poly(ethyleneoxy) units. Therefore, the process provides a method for making poly(ethyleneoxy) polymers without the need to polymerize ethylene oxide. The process is useful for making polyethers that are useful as water-absorbable polymers, surfactants and as raw materials for polyurethanes. The process is also useful for increasing the primary hydroxyl content of a polyether.

Mechanically competent scaffold for rotator cuff and tendon augmentation
Patent No. 9,757,132
A device has been developed to augment the rotator cuff tendon tissue as it proceeds in healing. The device has two purposes: to provide initial stability to the rotator cuff repair site to allow early mobilization of the upper extremity of the patient, and to allow for reinforcement of rotator cuff tendon repairs to increase the likelihood of successful rotator cuff tendon repairs. The device consists of an inter-connected, open pore structure that enables even and random distribution and in-growth of tendon cells. The braided structure allows for distribution of mechanical forces over a larger area of tissue at the fixation point(s).

PDU with front side access to transformer compartment
Patent No. 9,768,591
A PDU enclosure defines a transformer compartment for receiving a transformer. The PDU enclosure includes a first side bulkhead and a second side bulkhead positioned adjacent to each other as viewed on a plane. The first side bulkhead and the second side bulkhead limit access to the transformer compartment from the front. The first side bulkhead defines an opening to the transformer compartment and is spaced from the second side bulkhead by a gap. The PDU enclosure further includes a removable access panel. The removable access panel includes a first portion removably coupled to the first side bulkhead and that covers the opening in the first side bulkhead, and a second portion extending at an angle relative to the first portion and removably coupled to the second side bulkhead. The second portion also covers the gap between the first side bulkhead and the second side bulkhead.

Fiber-wrapped smokeless tobacco product
Patent No. 9,763,473
A fiber-wrapped smokeless tobacco product includes smokeless tobacco and a plurality of polymeric fibers surrounding the smokeless tobacco. The polymeric fibers can have a basis weight of 5 gsm or less and a diameter of less than 100 microns. In some cases, the polymeric fibers are melt-blown polymeric fibers. In some cases, the polymeric fibers are centrifugal force spun polymeric fibers. A method of preparing a fiber-wrapped smokeless tobacco product includes melt-blowing or centrifugal force spinning a plurality of polymeric fibers to create an polymer deposition zone and passing a body comprising smokeless tobacco through the polymer deposition zone. In some cases, an electrostatic charge can be applied to the plurality of polymeric fibers, the body, or a combination thereof. In some cases, a spin is applied to the body when passing through the polymer deposition zone.
