  • Bonding rubber to metal
    Patent number: 4211824
    Abstract: The bond strength of composite articles of rubber adhered to ferrous metal substrates through an adhesive is substantially improved at ambient and elevated temperatures by depositing a specified amount of a layer of copper on said ferrous metal substrate, applying an adhesive thereover comprising an interpolymer containing about 50 to about 99% by weight of a conjugated diene, about 1-45% by weight of a heterocyclic base and 0 to about 40% by weight of at least one additional copolymerizable monomer, thereafter contacting said adhesive with the rubbber to be bonded and bonding by heat and pressure.

  • Tire having beads with air relief means
    Patent number: 4209051
    Abstract: A pneumatic tire and a tire and wheel rim assembly are disclosed in which the tire has means preventing the tire remaining inflated when fitted to a non-matching wheel rim.The tire has a pair of axially spaced tire beads at least one of which has a circumferentially extending toe projecting axially and radially inwards of the bead. The toe has primary air relief means extending between axially inner and outer surfaces of the toe to prevent the toe effecting a seal with the rim bead seat or hump when the tire is fitted to a non-matching wheel rim.The tire bead having the toe may have secondary air relief means axially outboard of the primary air relief means to prevent the tire bead effecting a seal with the bead retaining flange when the tire is fitted to a non-matching wheel rim.

  • Traction devices
    Patent number: 4209049
    Abstract: There is disclosed in the present application a traction device adapted to being mounted on a driving wheel tire of a vehicle for obtaining greater traction on ice or snow although the device may also be useful in certain types of mud. The device comprises four spring arms each including a textured traction portion positioned across the face of the tire tread. The device is quickly mounted over the tire by collapsing and spreading apart the tread portions to permit bringing the device into engagement with the tire from a radial direction. The four arms in two pairs are then disposed at right angles to each other and are thereafter simultaneously tightened into embracing generally equally spaced relationship with the tire by turning a spring loaded crank.

  • Method of filling blind holes in a stencil
    Patent number: 4204610
    Abstract: The present invention is concerned with the loading of stencils comprising a plurality of blind bores or holes each adapted to accommodate a decorative article. The stencil is loaded by providing a stack of articles over the stencil and then producing relative translational movement between the stack and the stencil to deposit an article in each hole. Each article is of asymmetric configuration having a generally planar base so that when an article is deposited in a hole base downwards, the article is contained in the hole and when deposited in any other configuration, movement of the stack thereover urges the article out of the hole to allow another article to enter.

  • Methods for manufacturing cementitious reinforced panels
    Patent number: 4203788
    Abstract: Reinforced facings, including reinforcing webs entrained in hydraulic cement via a slurry bath, adhere to a nailable lightweight aggregate cementitious core to form a panel web. The reinforced web is formed on abutting conveyed carrier sheets, and the web is transversely cut, between the sheets, while moving or when stopped, in response to sensing of the sheets. The cut panels, on respective sheets are stacked for curing without damaging the panel edges and in a manner to minimize panel flex. Slurry bath, facing applicators, and cutter and stacking apparatus are included.

  • Pneumatic vehicle tire
    Patent number: 4203480
    Abstract: A slightly bulged outwardly arched pneumatic vehicle tire having a tread which is narrow in relation to the width of the tire. The tire also has a belt which is pull-resistant in the circumferential direction of the tire and effects the lateral stabilization of the tire. Portions of the belt are arranged on both sides of and adjacent to the tread in sections of the tire sidewalls which are essentially cylindrical or slightly conical. In addition, the reinforcing inserts form the belt. Those reinforcing inserts located in the tire sidewalls form a considerably smaller angle with the circumferential direction of the tire than do those reinforcing inserts located below the tread.

  • Air filter fabrication method
    Patent number: 4199387
    Abstract: An air filter unit of the pleated media, high efficiency type wherein the media pleat edges are sealed to the supporting frame to prevent bypass of air with a ceramic adhesive and fibrous ceramic mat which allows the unit to be exposed to high temperatures (e.g., up to 2000.degree. F.) without danger of seal breakdown. While in the form of a slurry the adhesive is applied, for example, with a trowel to the zig-zag pleated edges of the media which, together with corrugated spacers, forms the filter core. The latter is then surrounded on four sides by the compressible mat of fibrous ceramic material and inserted in a box-like support frame with the slurry filling the space between the pleated edges of the media and the fibrous mat.

  • Methods of making feminine hygienic pads with anterior leading edges
    Patent number: 4196562
    Abstract: Methods of making feminine hygienic pads from non-layered and layered material by use of folding, pressure molding and various methods of bonding to create a long geometric form with an anterior leading panel of narrow thickness and a thicker posterior underpanel of a wider thickness. The folded panels may be bonded by either a suitable adhesive, crimping, heat, pressure or ultrasonic means leaving an anterior portion with a leading anterior edge and a larger posterior portion. A filler may be inserted between the folds of the material prior to bonding. Thereafter, the long geometric form is multiple cut transversely providing pads about two inches long. These pads are used for insertion into the female interlabial space. The geometric configuration of the pads facilitates insertion of the pad via the anterior leading edge into the interlabial space and has improved retention within such space.
