Abstract: A sign for displaying prices and other information, in which at least one numeral character is changeable to display any numeral from zero through nine. A plurality of flap members are each pivotably attached to a flat foundation portion of the sign by resilient clips which hold a portion of each flap closely against a flat front side of the foundation member, thus holding the entire flap against the front side of the sign to prevent the flaps from being caught by wind. The flaps can be overturned by use of a tool including a spatula-like end, to display selectively a background colored face of the flap, covering a contrastingly colored portion of the foundation member, or to display the opposite face of the flap, which is of the contrasting color, and uncover the contrastingly colored portion of the foundation member. The spring clips are movable to permit the flap to be overturned, yet resiliently urge the flap against the front side of the foundation member at other times.

Abstract: A lathe for cutting a spiral strip of veneer from the surface of a log includes motor-driven mechanisms for adjusting the knife blade pitch angle and edge height, and for moving a pressure head relative to the knife to adjust the vertical gap and horizontal gap between the knife edge and the roller bar, and provides sensors for determining the actual positions of movable elements of the lathe, thus enabling computer-controlled adjustment of the movable elements of the lathe during lathe operation. A knife clamp of the lathe includes a plurality of separate clamp segments for pressing against different portions of a knife bar to hold it firmly, resisting deformation and rocking of the knife bar. Fluid-pressure-biased bearings eliminate looseness between relatively movable parts of the lathe, reducing the amount of variation of thickness in veneer produced using the lathe. Veneer thickness is controlled by monitoring cumulative movement of the lathe spindles and the main feed carriage.

Abstract: A sling swivel for removably attaching a sling of flat webbing or other strap material to a rifle or other firearm includes a loop member for receiving the webbing. The loop has a neck extending away from one side. A pivotable shaft carrying a movable link member extends through the neck and is spring-biased to urge the movable link toward the neck. A mounting pin is mounted on one end of the movable link member and is slidably receivable in a hole associated with the neck or a fixed link member. Moving the movable link from its normal position allows the mounting pin to be placed through an eye on a rifle, to attach the swivel to the rifle. The spring-biased pivotable shaft mounting pin is received within the hole. A stop extending from the neck, alongside the movable link, protects the movable link against being pushed away from the neck by an eye of a rifle on which the swivel may be mounted.
