Abstract: 966,427. Resilient joints. RIV OFFICINE DI VILLAR PEROSA S.p.A. July 2, 1962 [April 19, 1962], No. 25299/62. Heading F2S. In a resilient joint of the kind in which a sleeve 12, e.g. of rubber, is forced between two rigid metal bushings 10, 11 where it is radially compressed and axially elongated residual axialcomponent stresses in the sleeve, which tend to eject it from the bushings 10, 11 after it has been forced home into its final position therebetween, are eliminated by terminating the sleeve at one end at least by a radially-inwardly directed flange 14, Fig. 2. On inserting the inner bushing 11 into the body 12b of the sleeve in the direction of the arrow F the flange 14 is flared outwardly to form a collar 12a which abuts a flange 70a on the outer bushing 10. The internal diameter D5 of the flange 14 should generally be less than the axial length S.

Abstract: 940,576. Wood particle boards. NATIONAL STARCH & CHEMICAL CORPORATION. July 20, 1960 [July 20, 1959], No. 25319/60. Heading C3N. A wood particle board is produced by applying to one or both faces of a first layer comprising wood particles and binder, a methylolated cyclic monomer, alone or in admixture with wood particles, and then applying heat and pressure to effect curing and form the board. Suitable monomers are trimethylol phenol, furfuryl alcohol, resorcinol, and dimethylol phenol, the preferred amount used per face of the first layer being 2 to 20% based on the total weight of wood particles in the final board. The same amount of binder, e.g., urea-, or phenolformaldehyde, melamine-, alkyl-, or resorcinol-, resins, polyvinyl acetate, polyvinyl-chloride-acetate copolymers, corn or soybean gluten, corn starch and its derivatives, tung or linseed oil, may be used for the first layer, which may also include waterdispersible asphalt, wax-resin emulsions, wax, or flour. In forming the board the monomer may be spread on a tray and covered with the first layer and the whole compacted to a mat using heat and pressure, with or without a further top layer of monomer. The wood particles used preferably have a moisture content of from 1 to 15% by, weight and the final board may be veneered.

[Class 131.] In a hair waving or curling device of the kind comprising a shank around which the hair is coiled and an elastic cord or the like secured to one end of the shank and adapted to be detachably secured to the other, the shank is provided with a head which extends outwardly in a direction perpendicular or oblique to the plane or axis of the shank, the cord or the like being secured to the shank at the head end thereof, and the head serving to prevent the hair from slipping off the shank prior to the attachment of the cord or the like to the opposite end of the shank. The device may be made of wire bent in various ways to form a shank and a head projecting at right-angles therefrom. One such form is shown in Fig. 1, the cord 4 being secured to the head 2, and the shank 1 being formed at the end opposite to the head with prongs 1a over one of which, or over the shank, the ring 5 of the cord is engaged as desired. In modifications, the shank comprises a flat strap 1, Fig. 6, or a hollow rod, provided at the end with a head 2 having a perforation 3 through which the end of the cord is passed and knotted, the head being formed with a bent back portion if desired to cover the knot. In further modifications, the head comprises a stud projection from the shank, a ring attached at rightangles to a flat strip adapted to fit into an aperture formed in the end of the shank, or a rubber button 2, Fig. 12, adapted to be slipped on the end of the shank, which may consist of a flat strip 1 or a cylindrical or tapering rod. The shank may be corrugated or waved, and the ring 5 at the end of the cord may be replaced by a cap or, when the shank is hollow, by a peg. When the shank comprises a strip or rod, it may be provided with an elastic cord 8, Fig. 12, disposed along its length so that the device may be used as a curler, in which case the end of the hair is placed beneath the cord and the shank is then rotated to roll the hair thereon. An outer bow or guard of wire may be pivoted to the head end of the shank, the bow guard forming a finger grip or handle in its open position.

Sept. 18, 1933, No. 25772. Convention date, Sept. 20, 1932. [Class 38 (v)] Operatingmechanism for an automatic circuitbreaker comprises a collapsable thrust - transmitting toggle structure 1 and a tripping toggle linkage 5, the latter being rendered sensitive to comparatively small tripping forces by means of a restraining member 6 having a cam-surfaced notch 23 engaging a member of said linkage, a locking member 7 for the restraining member, and tripping means for the locking member. The actuating rod 3 of the circuit-breaker is connected through a pivoted lever 14 and link 15 to a link 8 pivoted at 9 to one end of the tripping toggle 5 and to a link 10 having a fixed pivot 11. The circuit-breaker is closed by energizing a winding 2, the plunger 2<1> engaging a roller 12 carried by the link 8 and raising the parts into the position shown, where they are held by a spring-controlled prop 4 which snaps under the pivot pin 13 of the roller 12. The locking member may be operated directly by a current coil 28, or indirectly, through a lever 29, by a voltage coil 30, to release the restraining member 6, whereupon the structure 1 collapses and the circuit-breaker opens. During the opening movement, a member 31 carried by one of the members of the tripping toggle linkage 5, temporarily holds the locking member 7 and permits automatic resetting of the linkage 5. Reference has been directed by the Comptroller to Specification 221,478, [Class 38 (v)].
