Abstract: A panoramic picture is taken to produce a negative with a panoramic image thereon, and a panoramic print is then made on a single sheet of double-wide photographic paper. The print is cut into two equal panels along a cutting line extending at right angles to the longitudinal axis of the print, and hinge members are fastened to the rear of the two panels along the cut edges. The hinge members are then secured in an album to mount the two picture panels in aligned, side-by-side relationship, with a narrow gap therebetween to prevent damage during closing and opening of the album. The hinge elements have a color tone corresponding to the general color tone of the central portion on the picture, to minimize the visibility of the gap. A triple-wide picture can also be made, with is divided into three panels, with the third panel being connected to the second by a hinge element.

Abstract: A cap-firing arm for a toy figure, the arm being frictionally secured for rotation at the shoulder of the figure by a hollow hub having a pinion gear internally of the figure. The arm is hollow and includes a spring-loaded hammer member slidably mounted therein with a cocking pin extending outwardly through a slot in the lower portion of the arm. The hammer member includes a firing pin adapted for coacting with an anvil secured within a hand mounting member which is slidable for loading the cap. The hammer member includes a tear drop shaped lobe extending through a similarly configured aperture adjacent to the shoulder portion and an actuating rod extending through the hollow hub disengages the lobe upon depression of a back plate of the figure which simultaneously elevates the arm to a horizontal position whereupon the cap is fired.

Abstract: A wheeled carrier for a lawn mower and edger which can be of the nylon line type. The mowing and edging tool is yieldably supported on a frame of the carrier to permit multi-directional operator controlled movement of the tool with respect to the carrier by manipulation of handle bars connected to a support for the cutter. The mounting permits steering a front wheel of the carrier by pressure applied to the handle bars. Rear wheels of the carrier are mounted to be fixed in different positions with respect to the front wheel, and parallel to each other to enable moving the carrier in different straight-line directions with respect to its longitudinal axis.
