Abstract: A rotary soil working tool comprising a rotatable support member having an engaging portion and a plurality of soil working elements each comprising an elongated member with a waisted portion. Each soil working element is detachably secured to the engaging portion such that the element extends outwardly of the support member. Preferably the support member is adapted to be rotabably supported on a hub.

Abstract: DNA sequence elements which effect anaerobic induction of genes in plants are identified and characterized. These sequence elements, designated anaerobic regulatory elements, confer inducibility by anaerobic conditions on downstress plant-expressible promoters and their associated structural genes. In particular, those sequences associated with anaerobic induction of the maize alcohol dehydrogenase and aldolase genes have been identified. These sequence elements can be employed in combination with appropriately positioned plant-expressible genes to produce chimeric, anaerobically inducible genes. Such constructs are useful for the selective expression of structural genes under anaerobic conditions in plants.

Abstract: A fluid flow control apparatus including a fluid flow portion configured to receive a flexible fluid container and an actuating portion which provides a variable force to the fluid flow portion thereby causing the fluid flow portion to pressurize the flexible fluid filled container.

Abstract: A method of detecting a deflated tire on a vehicle which includes sensing the angular velocity of each wheel and producing a signal proportional thereto, processing the four signals in a processor unit which subtracts the sum of the signals from one pair of diagonally opposite wheels from the sum of the signals from the other pair of diagonally opposite wheels, sensing when the magnitude of the result is between 0.05% and 0.60% of the mean of the two sums, comparing the signals for each of the four wheels in turn with the signals for each of the other wheels, sensing when one of said signals is different from the average of all four signals by more than 0.1% and in the event of both sensed signal factor being present, operating a warning device to indicate a tire is partially or completely deflated.

Abstract: A lead frame with parallel side members and parallel transverse members defining chip receiving areas along the frame, has a chip pad at each area. A support lead extends from each corner of the chip pad to corresponding conjunctions of side and transverse members. A U-shaped support bar extends between each adjacent pair of support leads, each support bar including spaced parallel leg portions connected at inner ends to the support leads and at the outer ends by a lead support portion. Leads extend from each lead support portion towards the chip pad. By this means the chip can be assembled to the pad and wire bonding between chip and leads carried out and the leads can be preformed or not, as desired, prior to encapsulation. After encapsulation, the lead support portions can be trimmed off but the encapsulated device is still held in the lead frame but the leads are electrically isolated from each other. Testing can be carried out while devices are still in the lead frame.
