Abstract: An apparatus for straightening damaged automobile frames or bodies utilizing a rigid structural ramp capable of supporting a vehicle. A preferably hydraulic power source capable of imparting alternatively a compressive or a tensile force to the damaged frame or body is adjustably mounted on a wheeled post which slidably travels a continuous track circumventing the ramp. The ramp is provided with improved chain anchoring openings. A chain can be used for a applying tensile force to the frame directly or indirectly to the frame by connecting a chain first to the anchoring opening, then to the damaged frame, and then to the hydraulic power source.Using two wheeled posts on the continuous track, a rotatable, pivotal, cross bar can be attached at its respective end portions to the wheeled posts. With the power source mounted on the cross bar, repairs can be made to the roof, or interior portions of an automobile (see FIG. 10).

Abstract: A slip-resistant binding is formed by attaching male and female-type Velcro strips along opposite ends of a shoelace or other binding material. The two types of Velcro fasteners are arranged such that fasteners of opposite type automatically engage one another at every point where the lace or binding crosses. Alternatively, two strips of opposite-type Velcro material are joined back to back to form a slip-resistant binding.

Abstract: The disclosure relates to a finishing treatment for fabrics, either tubular or knitted, having at least some natural fiber content, where the fabrics have been given a compressive shrinkage treatment by an asymmetrical process, sometimes referred to herein as "burnish compacting", in which one side of the fabric is acted upon differently than the other. The process of the invention eliminate or minimize "two sidedness" in the appearance of the fabric, which otherwise can be particularly noticeable with respect to colored fabrics. After passing through an asymmetrical compressive shrinkage process, the fabric is conveyed in a tension free manner through a moisturizing station, in which moisture is sprayed on the opposite surfaces of the fabric in the form of an extremely fine fog or mist, in quantities greater than the natural moisture regain of the fabric after compacting.

Handle molding material is introduced into the mold to form the handle. The material around the pin is then routed out forming a channel open at the bottom of the handle portion for receiving the handle string that may be readily looped about the pin.

Abstract: A method for production of a turntable which carries stroboscope marks with a metallic surface on the face side of its rim, the metallic surface relative to its dark colored intermediate spaces being elevated. In the edge vicinity of a disc which is made of good deformable metal and which by bending its edge downwardly forms the face side of the rim of the turntable, before the bending of the edge, recesses are stamped-in, which recesses correspond to the intermediate spaces of the stroboscope marks. After the bending and the dark coloring, the disc is lightly cut in the width of the stroboscope marks, which width is chosen somewhat smaller than that of the stamped-in intermediate spaces, in order to achieve a contrast in lightness between the lightly cut stroboscope marks and the deeper intermediate spaces. The turntable comprises a lower part substantially contributing to a flywheel mass, on which lower part there rests a disc as an upper plate, the disc being non-rotatable with respect to the lower part.

Abstract: Methods are disclosed for making a slot liner for electrically insulating electric coils from a magnetic core. The slot liner comprises a piece of insulating sheet material having first and second sides and first and second ends. The sheet material is folded upon itself in opposite directions at each end thereof to establish end portions of double thickness. In other words, the sheet material is folded back upon itself at the first end to lie adjacent the first side thereof to form a first end portion of double thickness; and folded back upon itself at the second end to lie adjacent the second side thereof to form a second end portion of double thickness. The double thickness ends may be further folded upon themselves (but in a common direction) to establish cuffs. In other words, the first and second ends of the sheet material of double thickness may be folded back upon themselves toward the first side of the sheet material to form a cuff at each end.

Abstract: There is disclosed a radiant heater having high efficiency, reduced cost, and longer life, and which allows rapid heat-up and cool-down. As in the prior art, a heating coil is placed in grooves formed in an insulating board; the radiating surface is a fiberglass cloth secured by adhesive to that face of the insulating board which contains the grooves and the wire coil. In making the heater of the invention, the cement is allowed to dry while the board and cloth are placed on a supporting surface with the cloth face down. The cement thus adheres primarily to that portion of the coil closest to the cloth. This manufacturing step results in a cement distribution which significantly affects both the cost, life and performance of the heater.

The first series extends to the measuring edge performing the measuring function, the second series pulling a short distance away from said edge providing a guidance means function while also indicating divisional breakdowns in fractions, millimeters and decimal hundredths.

Abstract: The present invention relates to a process for continuous countercurrent contacting with magnetically stabilized fluidized beds. More particularly, the invention relates to the operation of a magnetically stabilized bed with continuous solid addition and removal. The bed particles which include a magnetizable component are stabilized against gas by-passing and solids back-mixing (except possibly for the flow or movement of the solids near entrance or exit ports or near fluid injection zones) during countercurrent contacting by the use of an applied magnetic field. The process of the invention is particularly suited for carrying out separation processes. The use of the applied magnetic field in such processes enables one to use small size fluidizable, adsorbent particles without encountering high pressure drops.

Abstract: A fishing rig holder comprises three panel members foldably connected with ends of the first and third panels connected to the second panel. In folding, the second and third panels swing down and around the first panel. In a folded condition, the panels are stacked planarly with the first panel in the center, covered on one side by the second panel and on the other side by the third panel. The first and third panels include spring-actuated members for holding taut a fishing line, especially taut when the panels are folded in position because the fishing line is on the exterior of the folded panels. Alternate means are provided for maintaining the panels in a planar position when unfolded because otherwise the tension of the line tends to cause the panels to collapse. One of these means is provided by a locking position incorporated into the hinges connecting adjoining panels whereby the panels are locked into position when their ends are abutting.
