Abstract: Disclosed is an equal divider, including a mainframe and a plurality of indicator plates, wherein the mainframe is mainly made up of a plurality of first connecting rods and a plurality of second connecting rods pivoted by a plurality of pivoting structures to form a scissor structure. The mainframe is formed with a plurality of first pivoting parts and a plurality of second pivoting parts. The first pivoting parts and the second pivoting parts pivot the first connecting rods and the second connecting rods. The indicator plate is configured between the first connecting rod and the second connecting rod. The indicator plate is configured with a protruding indicating part. Each indicator plate is configured with a long through groove. The second pivoting part goes through the through groove. The indicating parts and the first pivoting parts maintain a fixed distance along the second axial direction.

Abstract: According to one embodiment, there is taught herein a family of “branched” variants of the traditional scissor mechanism, in which each stage is formed from more than two arms, joined at their midpoints by a branched rivet. In one embodiment arms in adjacent stages are joined at their endpoints with joints that allow for rotation in a single plane. Each resulting mechanism has one degree of freedom in its motion. It deploys from a compact, collapsed state to an extended state. One embodiment is a grasping member that is mechanically coupled to a scissor mechanism so that when scissor mechanism is collapsed the grasping member is open. Then, when the scissor mechanism is extended the grasping member becomes closed.

Abstract: An apparatus for cutting a duplicate form includes: a) a rack portion including a frame, a screen supported on the frame, and an arm support extension extending from the frame; the frame including an upper, generally horizontally oriented upper frame portion, and at least two corner frame members extending; and b) a movable arm portion pivotally connected to the arm support extension; the arm portion including a movable torch support arm segment including a cutting torch support mechanism, and a movable stylus support arm segment including a stylus support mechanism; a first end of the torch support arm segment being extendible into a central area of the frame below the upper frame portion; a first end of the stylus support arm segment being extendible above the upper frame portion and above the torch arm support segment. Also included is a method for cutting a duplicate of a template form.

Abstract: Process for producing multilayer ceramic substrates using greensheet technology and thin dielectric ceramic greensheets for miniaturization purposes. The process avoids the screening of the thin greensheets by forming self-supporting fusible particulate metal electrode layers, interposing them with the thin greensheets and sintering the assembly to form the multilayer substrates such as integrated capacitors.

Abstract: The torch of a machine for progressive contour bevel cutting of flat plates is mounted for controlled positioning and movement on an arcuate sector, the radius of which has a center lying in the horizontal plane of the plate. The torch is mounted for movement between adjustable stops which delineate two torch angles for cutting. A device is provided for substantially instantaneously moving the torch along the sector from adjacent one stop to the other stop. In the embodiment disclosed herein, the said device comprises a fluid-operated piston connected to the torch.

Abstract: A torch head is provided for an oxygen-cutting torch machine comprising, in combination, a torch head; a first torch mounted on the torch head for cutting perpendicular cuts; and a second torch mounted on the torch head for cutting at an angle to the perpendicular; the mounting for the second torch having two parallel side shaft members and two parallel cross shaft members, each pivotably attached to the other at spaced locations so as to define a parallelogram swinging means in which the four members move pivotably and in parallel together; the second torch being pivotably mounted to one of the side members so that the second torch can be positioned at an angle to the perpendicular according to the relative movement of the parallelogram members; a reciprocably movable drive means mounted on the torch head for swinging the parallelogram swinging means; a shaft member rotatable about a point fixed to the torch head and having two spaced pivot mountings, one on each side of the fixed point, one pivot mounting b
