Abstract: A tin opener intended for opening a tin by wholly or partially cutting away a part of the tin from the remainder. The actual cutting operation is effected by a cutter roll which can be rotated about an axis of rotation and which during the cutting operation is rotated by a drive shaft via a driving gear-wheel and a gear-wheel. During the cutting process the tin is supported by a feed roll which is in driving engagement with the tin and secured to the drive shaft. In order to enable a tin which is to be opened to be introduced between the cutter roll and the feed roll, or to enable a tin which has been opened to be removed therefrom, the cutter roll is mounted in such a way as to be capable of being rotated about a second axis away from the axis of the drive shaft and the feed roll. The mounting is such that the axis of rotation is inclined in relation to the other axis and extends at a distance from the latter.

Abstract: On a drill stand, a drilling member is movable between an inactive position spaced from the material to be drilled and an active position in contact with the material to be drilled. A marking element is mounted on the stand and is slidably movable between a retracted position and a marking position. In the marking position, a pointer on the element can mark the drilling axis on the material to be drilled. With the drilling axis located, the drilling member can be moved into the active position to commence drilling.

Abstract: A device and method for aligning the machine head of machines such as milling machines. A disk having a lapped flat surface is to be attached to the spindle of the machine, and the axis of the spindle can readily and accurately be set perpendicular to the two milling machine table axes. A hub is attached to the disk, with an axis vertical to the flat surface. The hub is used to attach the disk to the spindle. The disk has a plurality of equally spaced indicia around near its edge so that the high point and low point can be determined by placing a feeler gage on the machine table and tracking the flat surface. An axis accurately perpendicular to the machine head axis (spindle axis) will exist half-way between the high and low points on the edge disk as determined by the feeler gage. The machine head may now be accurately adjusted relative to the table by adjusting it so that a feeler gage shows no variation when the said perpendicular axis is tracked in the two milling machine table axial directions.

Abstract: The portable sign includes a display frame, a base having shafts for pivotably mounting the display frame on the base, first and second stops, one positioned on one side of the base, the other positioned diagonally across on the opposite side of the base. The spring structure has two springs, each engaging and winding only in one direction to prevent unwinding of the spring. Upon application of a force such as the wind to the display frame, the first spring engages the adjacent stop and tightens while the second spring disengages from the adjacent stop and rotates away from the stop. This allows deflection of the frame while protecting the spring from being unwound.A second embodiment of the portable sign includes a display frame, a base having shafts for pivotably mounting the display frame on the base, and a spring mechanism for biasing the display frame including a first bracket for retaining a spring, a spring, and a second bracket for slidably retaining a spring.

Abstract: The process of displaying indicia on a panel includes forming a panel with a substratum of a first selected material and at least one superstratum of a second contrasting material attached to the substratum. At least the superstratum is meltable, and preferably both layers are formed of tough, pliable, weatherproof plastic such as polyurethane. A heated indicia-forming tool is pressurally applied selectively to the superstratum to melt localized portions of its material throughout its thickness and force it out of the path of movement of the tool, leaving corresponding portions of the substratum exposed to define indicia with a contrasting background. The method can include also melting a portion of the substratum, having a contrasting color to the superstratum and causing a portion of the substratum to flow up over the melted raised portion of the superstratum along the edge of the melted area to form highly visible indicia on the panel.

Abstract: A gyroscopic walking toy is described having a housing adapted to be positioned for motion in a horizontal direction, a gyroscopic element rotatably mounted from the housing for rotation in a substantially vertical plane, a leg frame and a pivot for connecting the leg frame and the housing for pivotal movement therebetween. Relative movement of the leg frame and housing is produced by a crank geared to the gyroscopic element and linked to the leg frame whereby rotation of the gyroscopic element causes relative movement of the leg frame and the housing while maintaining the gyroscopic element in a substantially vertical plane thereby lifting one of the legs off a supporting surface. Feet can be rotatably positioned at the bottom of the leg since the housing and leg frame pivot around one foot when the other foot is elevated.

Abstract: Heretofore, commercial adobe construction has involved bricks or blocks of adobe (a sand and clay mixture prevalent in Western United States). In accordance with this invention, foundation footings of concrete are poured with the lower edges of wire mesh reinforcing material embedded or in otherwise attached to the horizontal foundation beams, one adjacent to each face of the adobe wall to be constructed. Since the adobe walls do not accommodate vertical bearing loads, holes are dug in the earth at spaced intervals to receive reinforcing bar cages and the lower ends of posts which carry the roof load. After the foundation has set, modular forms are applied along either face of the wall and interconnected, preferably by snap ties. Each form has a frame around four edges and vertical members spaced between the vertical edge members, all preferably of 2.times.4's. The inner face of each form carries a diamond pattern expanded metal member.
