Abstract: A table for vehicle includes a tray, at least one extendible leaf mounted movably on the tray between a deployed position and a withdrawn position. The extendible leaf is mounted translatably on the tray between the deployed position and the withdrawn position. The table further includes at least one rotatable leaf mounted rotatably on the extendible leaf between an idle position and a deployed position, and means for coupling movements of the second and rotatable leafs, which are configured to rotate the rotatable leaf from its idle position to its deployed position when the extendible leaf is translated from its deployed position to its withdrawn position.

Abstract: An automatic machine for providing corrugated sheet-like elements includes elements for the continuous corrugation of a ribbon which moves in a longitudinal direction. The corrugation elements include an upper conveyor and a lower conveyor. The upper conveyor includes a plurality of upper abutment elements extended substantially transversely with respect to the longitudinal direction of motion of the ribbon. The lower conveyor includes a plurality of lower abutment elements extended substantially transversely with respect to the longitudinal direction of motion of the ribbon. The upper abutment elements are interleaved with the lower abutment elements in a work area. The upper abutment elements each include a bar adapted to make contact with the ribbon, while the lower abutment elements each include a vane, which has a substantially wedge-like transverse cross-section and is adapted to receive the ribbon in order to deform it.

Abstract: An electrically heated chemical delivery system including a heat sensitive chemical and an electrical heater adjacent to the heat sensitive chemical. The heater includes a heater element with a first heater side and a second heater side and a flexible printed circuit in electrical contact with both the first heater side and the second heater side. The flexible printed circuit includes at least one fold allowing electrical contact with both the first heater side and the second heater side.

Abstract: A veneer for the veneering of especially curved surfaces has a face veneer formed from thin veneer sheets. The veneer sheets are adhesively bonded along their edges so as to be butted flush and on the side opposite the visible side to a mock veneer which is arranged underneath and which extends over the entire region of the face veneer. To maintain the relative movability between the veneer sheets and the mock veneer, an adhesive is coated on underneath the veneer sheets and is influenced in its setting reaction. In terms of the setting reaction, the adhesive is still reactive over a particular timespan. Thus, when the veneer is finally applied, the adhesive does not tear apart at the joints during a shaping curvature of the veneer because the adhesive in the joint region of adjacent edges of the veneer sheets is set completely.

Abstract: There is disclosed a method for the ammonia saturation of wood to impart flexibility thereto which includes the step of sealing the surfaces of ammonia-saturated wood with a polymeric film which has limited or no permeability to either or both ammonia and water vapor. Preferably, the polymeric film is flexible so the working of the wood product by bending, twisting, embossing, molding, etc. will not destroy the film. The polymeric film should also be soluble in a selected solvent, thereby permitting its removal after the wood has been formed in a final, desired shape to permit water vapor to re-establish crosslinking of the cellulose chains and restore its natural, rigid condition.

Abstract: A method and fixture for placing a permanent bend into a wooden pole. A channel shaped fixture receives the opposite ends of a wooden pole inserted therein and positions the pole above the bottom wall of the fixture. A cylindrical tube is forced downwardly against the pole by an external cylinder motor and in turn forces the pole against the bottom wall of the fixture thereby bending the pole. A pair of wedge shaped members are extended through the fixture and into the intermediate member thereby holding the intermediate member downwardly against the pole in a bent configuration while the external force is removed. The method of permanently bending a green pole includes positioning a green wooden pole shortly after harvesting in the holding fixture and then bending the pole to a bent configuration with the intermediate member. The fixture with pole in the bent configuration is then inserted into a dry kiln and heated.

Abstract: A method and apparatus for shaping flat rectangular shingle blanks into curved shingles includes a heating chamber and shingle shaping device. The shingle shaping device is comprised of an elongate upwardly convex fixed shaping member and a plurality of hingedly mounted, downwardly concave movable shaping members. A plurality of shingle blanks are first steamed and then place on edge in side-by-side relation between the fixed shaping member and the movable shaping members. The movable shaping members are then moved into closed clamping relation with the fixed shaping member to clamp the shingle blanks into curved configuration for use with roofs having a thatched cottage appearance.

Abstract: A method and apparatus for shaping wood materials into a predetermined configuration wherein the wood material is substantially saturated with water, heated, shaped and dried, and wherein microwave energy is used for at least the heating stage of the method.

Abstract: A woodworking technique for creating an angled corner in a straight wood piece. Formed on the inner side of the piece is a cut-out that is symmetrical with respect to a transverse reference line, the cut-out being constituted by a converging entry zone whose opposing flat sides have complementary angles each equal to one-half of the corner angle, the entry zone leading into an oblong interior zone whose opposing arcuate sides follow the curvature of a pair of circles. The wood bridge joining the arcuate sides of the interior zone is steamed to permit bending thereof to cause the arcuate sides to meet and the flat sides to abut on the reference line, thereby defining a circular socket for receiving a leg or other furniture component.
