The tube has an inflation valve and the wheel has a valve aperture. The method comprises in steps finding and marking a first portion of the wheel where the radial run-out value (RR) is the minimum and a second portion of the tire proper where the radial force variation value (RFV) is the maximum, disposing the tube in the tire proper, sliding the tube within the tire proper to a position where an angular position of the second portion relative to the inflation valve is equal to that of the first portion relative to the valve aperture, and coupling the tubed tire with the wheel having the inflation valve passed through the valve aperture.
Abstract: The modular pocketknife system is assembled from a number of modules. Each of these modules consists at least of a tool element (12, 13) and of at least one connecting element (8, 11). The modules can be ranged side by side in any desired number and sequence, the connecting elements being provided with an electronic contact element (1) for data transmission, a locking element (2, 4, 5), and a sealing element, so that the modules are fashioned splash-proofly mechanically and electronically interconnectible and lockable and detachable from one another again.
Abstract: Insulation is precisely cut and stripped from insulated electrical conductors by V type stripping blades. Precision cutting and stripping is assured by forming the blades with complementary and interlocking T and U-shaped cross sections. The blades have increased stiffness compared with prior blades even though the overall thickness of the blade pair does not exceed the overall thickness of prior blade pairs. A blade stop is interlockable with either stripping blade to precisely control the cutting hole size during production. An insulation stop is also interlockable with a selected blade for precisely locating the insulated electrical conductor relative to the blade cutting edges when the blades are closed over the conductor.
Abstract: An open-end ratchet wrench includes a handle element, a first jaw portion which is integrally formed with the handle element, a slide portion, a second jaw portion which is integrally formed with the slide portion, a restricting mechanism and a biasing spring. The slide portion is slidably mounted on the handle element so that the second jaw portion is positionable in a normal position wherein the first and second jaw portions cooperate to define a mouth for receiving the head of a fastening element and the biasing spring biases the second jaw portion toward the normal position thereof. The restricting mechanism maintains the second jaw portion in the normal position thereof when the wrench is manipulated to rotate the head of a fastening element in a first direction so that a turning force is applied to the fastening element.

Abstract: The fastener-handling tool disclosed is for the purpose of assisting in the starting of pointed fasteners such as nails, brads, tacks, screws and the like in instances where it is difficult or impossible for a person to hold the fastener conveniently between his thumb and fore-finger while driving the fastener with, for example, a hammer, screw-driver, etc. The tool comprises a one-piece molded elastomer element in which the handle part of convenient size has attached thereto a slender finger which is of substantially reduced cross-section and which has a hole at its free end for receiving the fastener. A slot leads cross-wise to the hole to enable the finger to be separated from the partially-driven fastener in a direction radial to the fastener. By way of an added feature, the handle part includes a pin cushion for carrying a supply of fasteners.
Abstract: A surface blasting apparatus including a wheel mounted chassis carrying a detachably mounted blasting head assembly. The blasting head assembly includes a housing enclosing a blasting wheel mounted for rotation about an axis extending parallel to a surface to be cleaned. The housing further includes a return chute through which abrasive returns after impacting such surface. A baffle assembly and magnetic arresting assembly cooperate to clean the abrasive particles by air washing. The air is then directed through a gravitating curtain of abrasive particles at a second cleaning location for further cleaning. The dust and debris laden air is then passed through a cyclonic separator and fitering system to clean the air prior to atmospheric discharge. Variously sized blasting head assemblies can be interchangeably mounted on the chassis for accomplishing various types of blast cleaning operations.
Abstract: A cylindrical and blade fuse puller is disclosed. The puller is made entirely of glass filled nylon and has a one-piece body with two sets of fuse jaws extending outwardly from the body at an angle to one another.

The post has high pitch threads which receive a restraining cone with mating threads. The post is engaged with the table through a central rim opening and the restraining cone is moved on the threads to engage the edges of the rim opening. The post-table engagement actuates an air interlock which enables the tire inflation system. The cone is trapped on the post by structure on either end of the post.
Abstract: A device for loosening and tightening the lids on jars or containers. The device has a handle, and a strap and brace attached to the handle. The strap is placed through the brace and formed into a loop so that it may be slipped over the lid. When a rotational force is applied to the handle, the brace pulls against the strap so as to apply a rotational force to the lid which is greater than the force applied to the handle. A spike extends from the top of the device which is placed through a hole in the strap to secure the strap to the handle. The strap has a series of holes to accommodate a large variation in sizes of lids. For loosening the lid, a counter-clockwise force, relative to the center of the lid when viewed from above, is applied to the handle. For tightening the lid, the handle is reversed and a clockwise force is applied to the handle.
Abstract: This invention is a socket insert to protect the finely finished surfaces of machinery and the nuts and bolts associated therewith. This protective insert is in the form of a nonmetallic material and is so sized that it will fit into a standard socket type tool with a smaller opening therein for engaging the nut or bolt to be manipulated. Because of a flare on the outer edge of the insert, the finish on the machinery that the nut or bolt is being used in conjunction with, will also be protected.
