    摘要： Squarylium compounds of the formula: wherein Q1 and Q2 are each independently a pyrylium, thiopyrylium, selenopyrylium, benzpyrylium, benzthiopyrylium or benzselenopyrylium nucleus, and R1 and R2 are each independently an aliphatic or cycloaliphatic group, can be prepared by reacting a squaric acid derivative of the formula: with a compound of the formula Q2CH2R2 in the presence of a base. The derivatives of Formula II may be prepared by condensing a 2,3,4,4-tetrahalocyclobut-2-en-1-one with a compound of the formula Q1CH2R1 in the presence of a base to produce a compound of the formula: wherein Q1 and R1 are as defined above, and X represents chlorine or bromine, and hydrolyzing the compound of Formula III. Alternatively, the derivatives of Formula II may be prepared by reacting a diester, monoacid chloride monoester or diacid chloride of squaric acid with a compound of the formula Q1CH2R1 in the presence of a base, followed by hydrolysis of the resultant monoacid chloride or monoester derivative of the compound of Formula II to the parent compound.

    摘要： A coupler for animal collars characterized by a novel combination of a releasable locking member biased in a normally closed position which is in the form of a curved resilient strip. This strip is adapted to receive a pair of post members provided on a channel-like base member which in turn receives respective ends of the collar which are held on the posts until the strip member is removed. The strip member may be removed by depressing the center portion which elongates the strip and permits its removal from the posts and their flanged top.

    摘要： A coupler for animal collars characterized by a novel combination of a releasable locking member in the form of a strip of metal which conveniently functions as a name plate. This strip is adapted to receive a pair of post members provided on a channel-like base member which in turn receives respective ends of the collar which are held on the posts until the strip member is removed. One of the posts includes a stop means and the other post is a threaded member adapted to receive a complementary threaded member disposed through spaced holes in the locking strip to effectively couple the ends of the collar together. Merely removing the threaded member from the threaded post permits quick removal of the strip from both posts.
