Abstract:
A servo operated system for controlling pressurization of an aircraft pils anti-G suit during high energy maneuvers has a servo operated control valve and a feedback loop controller for minimizing pressure lag in the suit. The controller has dual modes of operation: one for normal flight conditions and one for combat flight conditions. The normal flight mode provides nominal G-protection while the combat mode provides faster response by prepressurizing the anti-G suit to a bias level and lowering the G-force threshold. While in the combat mode, the crewman may select an adjustable pulsating signal to be superimposed on the prepressurization level to obtain additional comfort. Alternatively, he may select a superimposed pulsating signal which is synchronized with his own heartbeat to reinforce the pumping action of the heart.
Abstract:
A document sheet with a removably attached object thereon having simplified inexpensive construction and having a reduced cross-sectional thickness enabling use of the sheet in printers without the risk of jamming the printer. The document sheet also allows both sides of the object to be printed prior to its removal from the sheet with preferably at least 60% of the rear surface being accessible for printing through the use of an indentation window.
Abstract:
A configurable shield and methods related to same by which the ambient light in conventionally illuminated venues can be largely prevented from falling onto or around a screen such that images displayed on the screen are generally not degraded in quality. The configurable shield includes shield components that are preferably of a durable, yet light weight construction such that the components can be easily transported, assembled, and moved into position for use, then disassembled by one or a few individuals. The shield components include a shielding element—of a composition and having a construction such that the shield is generally non-translucent to light—and a sizable positioning element that provides additional structure to the shielding element and allows it, and thereby the entire shield to be positioned in a wide variety of configurations as needed such that the shielding element can be positioned adjacent to or in contact with the screen so that ambient light can be generally blocked from falling onto the viewing surface. An embodiment of the sizable positioning element is formable from a center lintel element to which an extension or extensions may be connected to form a horizontal element of the desired size and shape.

Abstract:
The present invention pertains to a document sheet or a business form formed as a single sheet or part of a continuous web of interconnected sheets where an indentation is pressed into a front surface of the sheet and an object such as a card, label or coin is releasably adhered to the sheet in the indentation, whereby recessing the object in the sheet indentation enables the simultaneous printing of both the document sheet and object.
Abstract:
A gravity protective system for pilots including a pressurized suit and a control system therefor for regulating the pressure in the suit in response to variations in acceleration along the thoracic axis of the pilot. Signals indicative of acceleration along the vertical axis of the aircraft and cosine function of the tilt angle of the pilot's seat are combined with a derivative function of their product to produce a control signal for regulating the air pressure within the suit. A threshold control limits regulation to acceleration above a predetermined level, and a feedback circuit from the suit ensures rapid response without oscillation.
Abstract:
A testing and treatment kit, a soil testing device and a procedure adapted for the home owner, especially for raising plants in containers. A stick having a pH-testing coating on one side and a nitrate-testing coating on the other side, the coatings changing colors during testing and being juxtaposed to colored sections for matching purposes to determine pH and nitrate levels. The ket including color-coded nitrate-increasing and acid-increasing pills, as well as color-coded fungicide and insecticide pills. The colored sections having indicia indicating the numbers of nitrate and acid pills to be added to a given quantity of water to produce solutions used in watering the soil properly correcting nitrate and acid soil conditions.
