Abstract: A system for maintaining a surcharge on a sanitary sewer collection system to minimize the pressure differential across pipe walls carrying the waste and to offset the buoyant effects of hydrostatic pressure on the outside of the pipe. Pinch valves or other remotely controllable pipe closing devices are employed in combination with a system of monitors and a centralized control system to maintain and periodically release fluid from the surcharged system.

Abstract: The present invention is a test milling method to determine the suitability of a grain for use in the derivation of desired end products. A full scale mill is simulated through a bench scale application wherein only a small portion of grain is required to conduct the test in contrast to testing protocols which employ full scale equipment. By utilizing the small scale simulations, hybrid varieties may be tested for total grit extraction and total yield well in advance of the many seasons that it takes to develop market quantities of a hybrid. The invention also relates to a method for determining which items of data collected are needed to accurately predict the total yield and grit extraction % and subsequently applying these limited data points in a shortened simulation to reduce the number of steps required in the test protocol. Data obtained from such tests may be used to direct hybrid research and select the best hybrids and shipments for the desired milling process.

Abstract: The present invention is an improved rotary granular material cutting apparatus and knife blade assembly. The apparatus comprises a perforated drum that may receive granular material into its interior. The grains of material extend through perforations in the spinning drum where they encounter a series of knife blades. The blades are arranged to form angles of contact with tangents to the spinning drum. Those angles of contact are steeper on the side regions of the spinning drum tan on the bottom regions. The apparatus also includes a grooved interior baffle to disburse input material within the drum, and knife-mounting wedges that include toe or base stops to help secure knife it blades in arrangement about the drum.

Abstract: A cammed vertical arm support system is described for the support and control of an expandable room that may be moved between a retracted position within a vehicle to an expanded position outward from the vehicle. The cammed relationship allows the room floor to lie above and generally parallel with the vehicle floor when the room is retracted and beside and generally flush with the vehicle floor when the room is extended. A moveable housing to conceal vertical arms is also disclosed.

Abstract: An air inlet device for use in automatically providing ventilation to the interior of buildings. The device has one of more openings each of which has a moveable louver pivoted at the lower side of the opening with the louver extending upwardly so that the inlet air is directed upwardly toward the ceiling of the building. Each louver extends beyond its lower pivot point and contains means for attaching weights of different amounts to the louver depending upon the static pressure within the building thereby allowing adjustment of the air flow in accordance with the static pressure.

Abstract: The present invention comprises a method and an apparatus for rapidly orienting and advancing buttons to be sewn. The invention employs a Programmable Logic Controller to control the steps of orientation and advancement and eliminates the need for time consuming set-up and adjustment of limit switches to control the movement of components within the button oriented and advancer. The use of a Controller to actuate the steps of orientation and advancement allows for the reduction of parts and consolidation of parts onto one plate that may be easily affixed to an industrial sewing head.

Abstract: A surface engaging implement having a surface penetrating member, a depth regulation member, a pressure sensor, a processor, and a variable controllable downpressure source is disclosed. The pressure sensor is disposed to detect loads upon the depth regulation member and to communicate load information to the processor. Through the processor, the controllable downpressure source may dynamically alter the pressure applied through the depth control structure to cause a desired excess downpressure and prevent an undesirably large or small amount of downpressure upon the depth regulation member. In this manner, a generally desired amount of excess downpressure may be dynamically maintained to maintain the ground penetrating member at a generally desired penetration depth.

Abstract: The disclosed invention is a protective device for use in combination with an elastic strap. Such straps commonly have hooks or other fasteners mounted on ends of the strap. When stretched and then released, these fasteners may become dangerous projectiles. In order to limit the rate of retraction or recoil of such elastic straps, the present invention discloses tethering the fastener end to the user's arm and/or retarding the motion of the strap with a sheath. In addition, the disclosure demonstrates a shielding apparatus to prevent direct contact with the fastening device or hook.

Abstract: The present invention relates to an improved sentinel lymph node localization wire for use in breast cancer patients undergoing nodal staging. A hollow wire having an anchoring hook at the distal end is inserted into the breast tissue through a loading needle. The anchoring hook, through spring action upon release from the loading needle, is embedded in the breast tissue near the location of cancerous cells. The loading needle is then removed and radioactive material may be injected into the tissue through perforations in the localization wire without leaving the needle in the patient or without reinserting the needle. A syringe attachment may be affixed to the proximal end of the hollow wire to facilitate the injection of radioactive material and blue dye for localizing the sentinel lymph node.
