Title: Method and composition for prolonging shelf-life of cut flowers
Inventor: CHACKAL JULIAN F
IPC: G01N33/483
Filed: 1992-07-28
Abstract: ABSTRACT     Method and composition for retarding bloom development thereby extending shelf life of fresh cut flowers (16) by "blanketing" and "feeding" techniques.  Fresh cut flowers, typified by roses are refrigerated and provided a blanketing confinement within a close environment of an essence of aromatic flower (such as lavender or rose) by the presence of essential flower oils or real aromatic flowers.  The essence is, effectively, a vapour blanket.  Cut stemmed (10) flowers are initially transported, stored or displayed in a container (18') of fresh water (19), in which a light or expanded magnesium carbonate sediment layer (21) provides cut flower end (14') envelopment for bacterial filtration, oxygen buffering and sufficient water-borne nutritional intake with or without the adjunct blanketing.  Additionally, freshness is made determinable by a simple testing process which will anticipate the value of applying or reapplying the carbonate treatment technique.

Title: Compliant Drive Link for Tenter
Inventor: DUNCAN JEFFREY B
IPC: D06C3/02
Filed: 1993-06-28
Abstract: A tentering machine having a compliant drive link allows for a considerable rate of stretch in a tentered fabric, web  or  film without the  distortion  or bowing  frequently observed with the tentering machines of the prior art.  The tentering machine includes two conveyor tracks adjacent to and facing one another, each conveyor track having a number of fabric edge holders slidingly directable thereabout.  A fabric, web or film, grasped on opposite edges by the fabric edge holders, is conveyed thereby through the tentering machine in the  space  between  the  two  conveyor  tracks.    Widthwise stretching occurs where the conveyor tracks of the tentering machine have sections on each side of the fabric which diverge from one another, while the two conveyor tracks may be parallel to each other on the two sides of the fabric in applications where prevention of shrinkage is of interest.  The fabric edge holders on each conveyor track are run at a substantially common speed by drive chains.  Elongated, spring-like compliant drive links extend from the drive chains to the fabric edge holders, but are not connected thereto.  The compliant drive links allow adjacent fabric edge holders to move relative to one another, permitting a considerable rate of stretch without the distortion or bowing of the fabric, web or film observed during the use of prior-art tentering machines.
