Abstract: A variable thickness fabric mat for use in railroad track structures, and particularly at stress transition zones in the railroad track; the mat is preferably formed of non-woven, multi-layered fabric, with the layers connected together, as for instance by needle punching to form an integral member. The mats are applicable for use with poor load bearing soils, and form a generally stepped, resilient bed for conventional railroad track structure, to help support and progressively spread the stress from the wheeled traffic, over a wider area. The mats provide for effective passing of runoff water, and aid in drainage of water from the soil beneath the mats, to thus improve the track support. The invention also provides a method of forming a railroad track construction so as to spread the stress from wheeled traffic at stress transition zones, over wider areas.

Abstract: There is disclosed herein a plastic lawn rake head or lawn broom head having a sheet-like body member, a rearwardly opening handle socket, a perpendicular wall around the edge of the body portion, and forwardly projecting raking prongs. The body portion is pleated to provide stiffness in the sheet-like area of said body portion while allowing the desired flexibility of the prongs.

Abstract: A plastic deformation is imparted to each of a sequence of load determining elements with the amount of deformation matching each element to a corresponding one of a sequence of element receiving workpieces to compensate for dimensional variation between the workpieces. A first fixture portion is abutted to a first workpiece portion and a second fixture portion is abutted to a second workpiece portion to provide a dimension defining separation between the fixture portions which is a function of a variable dimension of the abutted workpiece. The load determining or spacing element is then deformed the amount required for the particular abutted workpiece and the sequence of steps repeated to provide a plurality of matched elements and workpieces.

Abstract: A one-piece spring-type rail anchor of substantially uniform wall thickness, for gripping the base of a rail having laterally projecting flanges, is comprised of a bowed throat portion, a pair of generally C-shaped members extending from opposing ends of the throat and adapted for engaging respectively opposite edges of the rail base, and a pair of bearing surfaces located at the junctures of the throat and C-shaped members for engaging the bottom of the base of the rail at spaced locations thereof, said rail anchor having a generally inverted U-shaped cross-section throughout.

Abstract: A shaft for a golf club having steps angled obliquely relative to the axis of the shaft.

Abstract: A process is disclosed for forming the head of a golf club by rotating a blank, adapted to form the head, about an axis of rotation defined by the centerline of a bore in the blank that receives a shaft of the club. Controllable shaping means oriented with respect to the axis of rotation of the blank and disposed laterally thereof contacts and shapes the blank during its rotation.

Abstract: An impact tool such as, for instance, a hammer, having a pre-formed fiberglass handle. The handle includes a handle portion and a head portion, the latter being receivable in a socket in the striking head of the tool, with the head portion comprising a ribbed section and a non-ribbed section, with the ribs extending only lineally on the head portion generally lengthwise of the handle, and disposed in spaced relation circumferentially of the head portion, and with the non-ribbed section disposed adjacent the ribbed section and diverging rearwardly in the direction of the handle portion.

Abstract: Process for bleaching wooden articles by sequentially treating the articles with sodium carbonate, a hydrogen peroxide mist, and weak acid, with intermediate drying operations.

Abstract: A method employing a deformable metallic element is disclosed particularly characterized in that the element is formed of a hard resilient metal which undergoes work hardening when it is deformed beyond the elastic limit thereof. The element is made in the form of a relatively thin walled tubular member convoluted in longitudinal cross section. Upon axial compression the element undergoes a first period of resilient deformation during which the compressive force increases substantially linearly followed by a second period of plastic deformation during which the compressive force remains constant. The method is suited to imposing a substantially constant predetermined preload on a pair of opposed members.The element of the present invention is particularly useful as a load member to create a predetermined load on a part which it is desired to maintain under a predetermined constant load.

Abstract: An improved precipitation hardening or maraging stainless steel for use in Tubular Sporting Implements, particularly golf shafts containing chromium, molybdenum and nickel, the sum of said chromium, molybdenum and nickel being at least 18% and not exceeding 25%, at least one element selected from the group consisting of aluminum and titanium in a maximum of 1.30%, carbon in a maximum amount of 0.06%, manganese 0.50% maximum, silicon 0.30% maximum, the balance being essentially iron and incidental impurities.

Abstract: Apparatus for cutting vegetation comprising a disc mounted for rotation in a generally horizontal plane, a support member protruding from the disc for receiving a cutting blade, an elongated, rigid plastic cutting blade pivotally mounted on the support member and a counterbalance to the cutting blade on the disc for stabilizing the apparatus; the cutting blade extending radially as the disc rotates, to cut vegetation in its path.

Abstract: A radio frequency antenna comprising a shaft fabricated from dielectric material, and first and second conducting means disposed on the exterior surface of the shaft, the conducting means including linear conductors located on opposite sides of one portion of the shaft and intertwined insulated coils on a second portion of the shaft connected to the respective linear conductors. Tuning members can be connected to the conducting means for selectively changing the resonant frequency of the antenna.

Abstract: A cordless earth tiller has a housing mounted upon wheels and including a handle for guiding and controlling the tiller and tilting the same in a fore-and-aft direction. A power driven crankshaft disposed forwardly of the wheels carries a plurality of arms which depend from crankpins of the crankshaft and are provided at their lower ends with tines. Links are pivotally connected at one end to the arms and at the other end to an axle of the wheels whereby rotation of the crankshaft causes a tilling or cultivating motion of the tines. The tines sequentially impinge upon the ground in a substantially vertical direction and proceed through the ground at a rearward inclination to draw the tiller through the ground in response to rotation of the crankshaft. Modifications comprise the use of harrowing disks as wheels and the substitution of ice chipping tools for the tines, etc.

Abstract: A base station radio antenna comprising a bracket having a first section for attachment to a support structure and a second section for receiving antenna whips, an antenna whip extending upwardly from a central opening in the second section of the bracket, and a plurality of antenna whips inclined relative to the upwardly extending antenna whip and extending generally downwardly from openings in the second section spaced radially from, and equi-angularly around, the central opening.

Abstract: A pendulum type hoe has a stirrup-shaped blade mounted to the fork of a handle for limited articulation. Inturned flanges of the blade engage hourglass shaped openings in the fork arms, the flanges being retained between reinforcing bars which project through the openings and afford strength, wear resistance, and limited resilience to the blade. The fork is made in two separable parts whereby any component of the hoe may be replaced.

Abstract: There is disclosed herein a battery operated power grass shear wherein a fixed blade and a superimposed laterally oscillating movable blade have forwardly projecting, laterally spaced cutting teeth, the planes of said blades being tilted convergently relative to each other in the forward direction, the teeth of the upper and lower blades contacting each other only at the cutting edges thereof during cutting movements, and each tooth of the movable blade beginning its cutting stroke at a different time in each cutting cycle.
