Abstract: A golf putter head has a central portion made of a relatively light weight material such as a light alloy of extruded aluminum or extruded plastic alloy. To further reduce the weight of the central portion, this portion may be extruded and the face plate formed from a light polymer or rubber material. The toe and heel portions of the head are separately formed of a relatively heavy material such as sintered tungsten or tungsten copper. The toe and heel portions are similar to each other and are attached to the central portion by means of pins which fit into opposing holes formed in the ends of the central portion and the toe and heel end portions as well as well as screws which fit through apertures in the end portions and engage threads formed in the central portion. Employing a central portion which is much lighter in weight than the end portions provides an anti-twisting motion of inertia to the club head.

Abstract: A shoe brush is mounted for slidable motion between a retracted position and an extended position. The brush is fixedly attached to longitudinally extending support members which are mounted for slidable motion on a support which is fixedly connected to the underside of a vehicle. A spring assembly is connected to the brush support urging the brush to the retracted position. The brush is drawn outwardly against the tension of the spring assembly to an extended position for utilization in brushing shoes. A latch member retains the brush in this extended position unless and until it is released to permit the spring to draw the brush to the retracted position.

Abstract: A single cylindrical chamber has a drive shaft rotatably mounted therein and extending along substantially the entire length thereof. This drive shaft is rotatably driven by a motor at a speed of 2000-5000 rpm, this speed being chosen so that the natural resonant frequency of the various components of the system is at least three times this rotation speed. Solid dry coarse particles to be comminuted which may be of coal, limestone/dolomite, cement or lime are fed into the chamber. Pressurized air is fed into the bottom of the chamber which in conjunction with a stationary velocity head provides uplifting pressure for driving the air and particles upwardly in the chamber. The upwardly driven particles are first driven through a plurality of rotors which are driven by the shaft and provide a centrifugal force which forms them into a vertical toroidal fluid bed that allows increased tonnage production and comminutes the particles.

Abstract: A buckle which is used to removably fasten two pieces of webbing, strap or the like together requires two distinct actions for its opening and thus is “double locking.” A latch member is pivotally supported on a frame by means of a support shaft. A first strap end is fixedly attached to one end of the frame. A second strap end to be attached to the first strap end is removably attached to one end of an adjuster member. The other end of the adjuster member is T-shaped. The frame has a pair of opposing ledge portions which extend opposite the base portion of the frame, opposing slots being formed between these portions. The top of the “T” of the adjuster member fits into the slots to retain the adjuster member to the frame when tension is placed on the second strap end portion thereby providing a first locking action. The latch member has a detent formed thereon which engages a detent on the end of the ledge portion of the frame.

Abstract: A roller tray assembly has a plurality of roller wheels mounted on the floor of a loading platform of a vehicle such as an aircraft or truck. The roller wheels are free to roll either in the loading or unloading directions to permit cargo to be loaded or unloaded on such wheels. Braking rollers are installed on the loading platform floor, the cargo load being moved over such braking rollers. Each braking roller has a central hub supported on unidirectional clutch bearings such that the roller is free to rotate in one direction but locked by the bearings against rotation in the opposite direction. The outer wall of the central hub is covered with an elastomer. The roller has an outer cylindrical wall against which the cargo abuts. The ends of the cylindrical wall have end covers between which a plurality of rods are mounted. These rods abut against the elastomer with sufficient pressure to deform the elastomer. The central hub is rotatably mounted on a fixed shaft.

Abstract: A wheel chock is formed from a bar which is bent to form opposing bottom arms; a first pair of opposing side arms which run above the bottom arms and are slightly upturned therefrom: a second pair of opposing side arms which run upwardly from the first pair of side arms; and cross arms forming a top portion which runs between the second pair of side arms. A base plate is attached to the bottom arms, this base plate having studs attached thereto and extending from the bottom thereof. The studs fit into a track fixedly attached to the floor of a transporting vehicle which may be an aircraft or a truck. A central plunger latching member which is spring loaded also extends from the bottom of the base plate and latches the plate to the track. The chock can thus be installed in and removed from the track merely by manually positioning the latching member.

Abstract: A cover is installed over an engine adjuster such as a carburetor adjustment screw. This cover is in the form of a cap having a flat top with a frangible brim portion. The cap is installed in a housing for the adjustment device, in a recess directly above the adjustment device. An inner rim is formed on the cap beneath the flat top with a recessed portion being formed between the top and the rim. The inner rim of the cap matingly engages a rim which may be formed in the top portion of the adjuster or in a housing surrounding the adjuster and snaps into place joined to either the adjuster or its housing. An anti-pry protective washer or shoulder is provided in the housing. This anti pry device is positioned in close proximity to the outer wall of the inner rim of the cap in a manner to prevent prying instruments from reaching under the inner rim in an attempt to remove the cap.

Abstract: A Luneberg lens has a plurality of feeds arranged to send and receive signals to and from a plurality of satellites. The lens is spherical and is fixedly supported on a support mount. Also supported on this mount are a plurality of arcuate positioner tracks which form arcs parallel to the surface of the lens. Each of the feeds is mounted on a separate one of these tracks. The tracks are supported on the mount for separate pivotal motion along separate paths equidistant from the surface of the lens about a “y” axis relative to the lens. A motor is coupled to the drive of each of the tracks to pivotally drive its associated track in response to control signals. The feeds are mounted on the tracks for motion in paths about an “x” axis relative to the lens, such paths being equidistant from the surface of such lens. A motor drives each of the feeds in response to control signals along separate paths parallel to the lens surface.

Abstract: A golf club head is formed from two separate pieces. One of such pieces constitutes the face plate while the other piece constitutes the sole plate and the top crown of the club head. The pieces are welded together to form a hollow shell. The sole plate and the top crown are connected together with a hinge. These hinged pieces are joined in a closed position in a nest die and spot welded together. The face plate is then seam welded to the sole plate and the top crown in an argon chamber to form an integral unit.

Abstract: A wide-band feed for a reflector antenna that provides a sum and a difference radiation pattern for tracking and for the transmission or reception of data. The feed utilizes two coaxially located, coaxial waveguides. The inner coaxial waveguide supports propagation of the TE11 mode and produces a sum radiation pattern. The outer coaxial waveguide supports propagation of the TE21 mode and produces a difference radiation pattern. The dimensions of the inner and outer waveguides are selected such that the dispersions of the TE11 mode in the inner coaxial waveguide and the TE21 mode in the outer coaxial waveguide are the same. Coaxial chokes located near the open ends of the wave guide modify the impedance match to free space of the fields within the waveguides and modify the radiation patterns generated by the waveguides. Probes within the waveguides generate the respective modes.

Abstract: A braking device for braking the motion of cargo in a roller system for use in loading and unloading cargo has its main frame mounted on the loading floor. An arm assembly having a pair of opposing arms is pivotally supported on a shaft supported on the main frame near the center thereof, this shaft extending transversely of the longitudinal axis of the frame. A substantially flat brake pad made of a friction material is pivotally supported on the arms on one side of the longitudinal axis of the shaft. A roller wheel is pivotally supported between the arms on the side of the longitudinal axis of the shaft opposite to that on which the brake pad is supported.

Abstract: A retractable roller system has a main channel mounted on the floor of a vehicle into which cargo is to be loaded. A pneumatically actuated bladder is mounted along the bottom of the channel and a roller tray on which a plurality of roller members are rotatably supported is mounted in the channel above the bladder. Flange members extend inwardly from the side walls of the channel at different vertical levels. Flange members extend outwardly at different vertical levels from the opposing side walls of the roller tray. The rollers are raised to handle the loading of cargo by inflating the bladder and lowered to recess the rollers below the level of a cover plate to keep the cargo in a desired location. The cover plate utilizes a minimum number of screws in conjunction with a mating coupler plate and slots and for adjacent units which engage pins on the channel to provide secure retention of the plate yet facilitating ready removal when the roller tray needs to be removed for repair or replacement.

Abstract: A golf tee has a collar thereon which forms a stop when the tee is placed in the ground to set the top of the tee at a predetermined height above the ground. The collar position is set in separate tees for each golf club and for each golfer so that when the ball is placed on the tee, the head of the golf club will strike the ball at an optimum position, as may be desired. A modification of the basic device uses an extension piece which fits into the top of the tee so that the same tee can be adapted by using different length extension pieces to satisfy various height requirements. This extension piece has a tee seat for the ball on one end and a pin on the other end which fits into a hole formed in the ball seat of the tee.
