Filed: 1993-03-26
Abstract: SIMULTANEOUS  TDMA  COMMUNICATION  SYSTEM                 ABSTRACT OF THE DISCLOSURE    A network of satellites delivers communications through bi-directional communication links between individual ones of the satellites.  Each satellite terminates a plurality of links.  All satellites are synchronized to recognize a constant duration frame structure.  For each link in the network, satellites at both ends of the link simultaneously transmit data communications into their respective ends of the link using the same frequency band.  Transmissions into all links supported by a satellite occur simultaneously. The transmissions continue for a duration that is responsive to the distance between the satellites. Transmissions cease for all links supported by a satellite when the communications from the opposing link nodes have nearly propagated the entire distances between the satellites.  After ceasing transmissions, each satellite receives the communications previously transmitted from the opposing satellites into the links therebetween.

Title: Screw Designs for a Scissors Jack
Inventor: ENGEL DARRYL L
IPC: B66F3/12
Filed: 1993-06-09
Abstract: An improved scissors jack which has a lead screw that does not extend beyond the confines of the jack when the jack is in the partially raised position so as to reduce the space required for storing the jack. A holiow member is formed with a slot in which the extension of the threaded screw is received so that the end of the screw can slide in the slot when the jack is in the unloaded position to allow the jack to be raised to a mid height condition for storage. Under use, the extending portion of the screw moves to the end of the slot in the hollow member so as to apply tension to the lead screw to thus raise and lower the jack as the lead screw is rotated.       A modified form of the invention utilizes an extended hollow trunion which prevents the end of the lead screw from extending beyond the confines of the trunion and a further modification provides for pivotally connecting two portions of the lead screw so that the jack can be moved to a stored condition.
Patent CA-2100688-A1 (CA)
Title: Environmentally controlled packaging for produce and method of use therefor
Inventor: BROWN RICHARD S
IPC: B65D81/20
Filed: 1993-07-16
Abstract: ABSTRACT OF THE DISCLOSURE    A container system which is environmentally controlled for the packaging and shipment of vegetables, and particularly of lettuce, such as iceberg lettuce.   The packaging relies upon a reusable paperboard container which is of a polygonal shape, such as an octagonal shape, providing a large number of corner margins which afford strength in stacking of like containers on pallets.   A plastic liner is disposed within the paperboard container and receives the vegetables such as the heads of lettuce.  This liner is evacuated through a small incision made in the liner and the liner is sealed, or the former air atmosphere is replaced with a modified atmosphere, such as a high carbon monoxide concentration or nitrogen atmosphere, and thereafter, the opening is sealed.  The modified atmosphere precludes the oxidation and deterioration of the lettuce or other vegetable product.   In a more preferred embodiment, a pair of plastic liners, comprising inner and outer liners, are employed.  When the inner liner is filled, the pair of liners are then rolled over and sealed.  A small incision is made in  the  inner  liner  in  order to  evacuate  the  air  from  the environment in which the lettuce is held.  Thereafter, the small opening used for evacuating the air is sealed.  The same procedure takes place with the second or outer liner in that it is evacuated and charged with a modified carbon monoxide or nitrogen atmosphere and the opening thereof sealed.  In this way, if there is a leak in the inner liner,  the lettuce or other vegetable will only be exposed to the modified carbon monoxide or nitrogen atmosphere and not  oxygen  which  causes  a  very  rapid  deterioration  of  the vegetables.  Leakage through the outer liner will not injure the vegetables as long as the inner liner remains secure and intact.

Filed: 1993-12-14
Abstract: METHOD AND APPARATUS FOR PRODUCING SOLID FERTILIZER FROM LIQUID SUBSTANCES SUCH AS MANURE FROM LIVESTOCK OR SLUDGE            Background of the Invention: Field of the Invention: The invention relates to a method and an apparatus for producing solid fertilizer from liquid substances such as manure from livestock or sludge.            Liquid manure production around the world is enormous. The escape of gases from liquid manure is not only malodorous but it also contributes to the global greenhouse effect and the much publicized ozone hole. Moreover, liquid manure is a danger to the groundwater when - in the old, time-honored way - the liquid manure, in its original form, is spread, as fertilizer on agricultural areas by spraying onto or other introduction into the soil. Similarproblems are associated with the immense worldwide production of sludge, for instance from water purification systems.            There is accordingly a need for alternative methods that solve these problems associated with liquid manure and sludge in an environmentally appropriate manner and that at the same time enable the utilization, for soils used in agriculture, of the valuable substances contained in the fertilizer.
