Filed: 1953-11-30
Abstract: 742,226. Dams. AUBERT, J. Nov. 30, 1953, No. 33256/53. Class 68(2) In a dam flashboard assembly, having a flashboard H, a strut a and a slide consisting of a channel g and a rack c with notches d 1 , d 2 , d 3  against which the foot p of the strut a rests, an improved slide comprises two channels L 1,  L 2  and a rack divided into sections N 1 , N 2 . Motion is imparted to the foot p by altering the inclination of the flashboard H and, in the prior art, the foot cannot be moved directly from one notch to the next down the rack without describing an almost complete loop which passes through both the end positions O and IV. In the improved rack the foot may be moved from position III on the Tack section N 2  to position IV by drawing it upstream off section N 2  whence it falls at 2 from a part S 12  connecting an offset portion of the rack S 8  and, after reversing at 3, passes along path 4 in channel L 2 . The path from position II on section N, to position III involves a circuit in which the foot p has first to. be drawn upstream into position I. It is then lifted by surface S, and slides across to position O. On reaching the top of section S 8  (Fig. 8b), inclined surface S,. (Fig. 8c) ensures that the foot p falls onto section N 2 . Channel L 2  is used for returning from position I, after crossing S 2 . to position IV. Panel S, guides the foot from position O up the slope S 2  whence it falls into channel L 2 . The foot p moves up the rack as in the prior art and is prevented from straying in the space between N, and N 2  by guide panel S 6 . G is a depression in which the foot rests when the rack is completely down.

Abstract: 1,128,200. Stiffeners. BIXBY BOX TOE CO. Inc. 25 July, 1967 [10 Aug., 1966], No. 34090/67. Heading A3B. [Also in Division C3] A stiffener, particularly a toe puff, is formed from a thermoplastic resin incorporating 0.25 to 2.5% by weight of a release wax which is thermally stable up to 500‹F., has a melting point over 212‹F. and is slightly incompatible with the resin at ambient temperatures whereby the wax migrates to the surface of the 2 resin without significantly reducing the tensile strength of the stiffener. Suggested resins are copolyesters or a mixture of copolyesters and the suggested wax is N, N<SP>1</SP>- methylene-bis-stear-amide. The blended compositiion is melted and formed into a toe puff in an open mould. The mould is cooled, solidifying the mould-contacting surface of the toe puff and whilst the exposed surface remains tacky it is pressed against a flexible shoe upper. The mould is then withdrawn. The migration of the wax to the surface of the stiffener on cooling enables easy release of the stiffener from the mould cavity and prevents its sticking e.g. to a last in subsequent operations.
