Abstract: A mailbox accessory device for insertion within the cavity of a mailbox for more easily accessing mail located towards the rear portion of the mailbox including a first member extending along at least a portion of the length of the mailbox cavity, the second member being coupled to the first member. The mailbox device is movable within the mailbox cavity from a position wherein the second member lies in the vicinity of the rear wall of the mailbox to a position wherein the second member lies in the vicinity of the access opening of the mailbox. The second member extends above the first member and engages mail located in the mailbox cavity so as to move such mail to the access opening of the mailbox.

Abstract: A process for the synthesis of linear ?,?-diolefins from an allylic substrate comprises the steps of a) forming the bis-Grignard reagent XMgCH2(CH2)nCH2MgX from an ?,?-acyclic dihalide with X being a halogen; b) preparing a solution comprising an allylic substrate and a copper catalyst; c) catalyzing a coupling reaction by adding to the solution of step (b) the bis-Grignard reagent of step (a); and d) isolating and purifying the ?,?-olefin coupling reaction product.

Abstract: A strip curtain system having an elongated track adapted to be mounted over a doorway and having two spaced apart rails, a plurality of curtain strips and a plurality of hangers. Each curtain strip has a top end portion and a main body portion. The top end portion has at least one hole therethrough and a width less than the width of the main body portions. Each hanger has a male plate with at least one peg and a female plate with at least one hole sized to receive the male plate peg. A strip curtain may be assembled in the doorway by mounting the track thereabove, mounting the hangers to the top end portions of the strips, and sliding the hangers upon the track into abutment with one another with only the main bodies of adjacent strips suspended therefrom overlaying one another beneath the track.
