Abstract: A roller assembly is removably mounted on the floor of a vehicle. This assembly has a retracted configuration adapted for moving cargo therelong in a first direction and an erected configuration for moving cargo in a second direction normal to the first direction. A first set of rollers is mounted in the assembly for universal movement. A second set of rollers is mounted for rotational movement about a first axis while a third set of rollers is mounted for rotational movement about a second axis normal to said first axis. In the retracted configuration, the first and second set of rollers facilitate the movement of the cargo in the first direction, the third set of rollers being below the support surface of the assembly so as not to interfere with such movement. A sub-assembly on which the third set of rollers is rotatably mounted is spring urged to the erected position by manual release of a latch.

Abstract: A cargo securing device is removably mounted on the floor of a vehicle such as an aircraft, this device being adapted to guide palletized loads to prevent substantial movement thereof during transportation. The device is spring urged to a retracted position wherein it lies substantially flat to permit the passage of cargo thereover during loading. The device is manually raised to its operative position against the spring action. When in its raised operative position, a pair of locking pins slidably mounted on the central portion of the device are spring urged into channels formed in an outer support portion of the device to retain the device in the raised position. A lever is manually operated to withdraw the locking pins from the channels thereby permitting the device to be driven by the spring to its retracted position. In its raised operative position, the device has a dog which engages the base of a pallet to restrict vertical movement thereof.

Abstract: A slide plate is attached to a support member which is supported on a work bench for pivotal motion about a longitudinal axis. The slide plate is pivotally attached to such support member through a coupler to which a resilient vertical torquing force is applied by means of a spring member. This resilient force urges the slide plate pivotally upwardly to an angular position against a stop member where it is retained except when downward pressure is exerted thereagainst, as in sawing. The slide plate has an aperture therein such that a circular saw can be fitted in the aperture and slidably moved along the slide plate in performing a sawing operation. The slide plate support member is mounted on a work bench which has a fence member thereon for stopping the downward travel of the slide plate to provide a space between the slide plate and the work bench for the piece to be sawed.

Abstract: An instrument for cutting paper or similar planar sheet material is provided which comprises a cutter blade mounted in a head portion for rotation about an axis, an elongate handle portion and a neck portion connecting the head portion to the handle portion.The handle portion extends at an acute angle with respect to the axis of rotation of the cutter blade whereby, when the instrument is in its position of use with the cutter blade in contact with a sheet to be cut and the axis of rotation of the cutter blade substantially vertical, the axis of rotation of the cutter blade and the longitudinal axis of the handle portion, when extended, intersect at a point on the opposite side of the planar sheet from the cutter blade and spaced therefrom.

Abstract: A polygonal element is provided for forming polyhedral structures, particularly for use as an educational constructional toy. The polygonal element has side margins each comprising an inner edge, an outer edge, first and second projections extending outwardly of the outer edge and a recess defined by the first and second projections. The first projection comprises a pair of spaced limbs unconnected at their outer ends. The side face of the recess defined by an inner limb of the first projection is an abutment face. One of the side faces of the recess opposite the abutment face and the outer side face of the outer of said limbs is provided with a projecting hinge pip and the other with a corresponding hinge socket.

Abstract: A golf club head of cast metal has a cavity formed in the face portion thereof, this cavity being filled with an alloyed material formed from a blended mixture of metallic, refractory, and polymer powders. The golf club head is preheated before the mixture is placed in the club head cavity. After being installed in the cavity the mixture is heated and compressed by the application of force thereto to form a consolidated face plate for the club head which is adhered to the walls of the cavity by virtue of the adhesive properties of the polymer.

Abstract: A flat retainer device has elongated fingers on the left and right sides thereof, said fingers running opposite a side wall of the central portion of the retainer. A slot is formed between each of the fingers and the central portion, the fingers and the main body portion forming a locking hook structure. A protuberance is formed on the lower portion of each side of the central portions opposite each finger, these protuberances closing off most of the opening to the slot on the free end of the fingers. The left and right hand sides of the device are mirror images of each other and have the same structural characteristics. The top and bottom ends of the central portion of the device have indentations formed therein. An elongated groove is formed in the slat, the length of this groove being designed to receive the central portion of the retainer member with the indentations thereof abutting against the end walls of the groove in a force fit relationship.

Abstract: A golf bag has a retractable towel attachment mounted thereon. This attachment is formed by a spring loaded reel mechanism which is mounted in a compartment formed in a top inner portion of the bag, this reel portion having a line wound around it and normally held in a wound up state by the spring action of the reel. The line runs through an aperture in a side wall of the bag to an outer wall of the bag and has an attachment member on the free end thereof which is used to removably attach the line to a towel. The attachment member also operates to retain the end of the line against the side wall of the bag. The towel can be pulled away from the bag against the spring action of the reel for use in cleaning golf clubs, golf balls or other items and when released is retained along the side wall of the bag. The towel is readily removable from the attachment member for replacement when required.

Abstract: An adapter having solderless wire terminals for receiving the wire leads from an electrical equipment such as a radio or stereo player set is installed on the back of such set. Such terminals have solderless spring connectors for the wire leads, these connectors employing a pair of opposing apertured fingers which overlap when manually urged together against the spring action to permit the insertion of a wire lead in the aperture thereof and to be retained therein by the spring action. The equipment or stereo set is removably installed in a mounting frame which is mounted in the vehicle. The mounting frame has a terminal therein which the terminal of the set matingly engages to provide electrical connections therebetween. The terminal of the mounting frame has solderless spring connectors similar to those of the terminal of the equipment, such connectors receiving the various wiring leads from the equipment to the power source, speakers, etc.

Abstract: An unpowered air vehicle, i.e. a glider, which is air-launched from appreciable range, is densely packed with a large area, explosive net. At a pre-determined location, the net is extracted from the glider by a parachute and expanded completely before landing on the surface of the water or land that contains a large field of mines. The explosive material in the net is then detonated, destroying the mines covered by the net. The longitudinal ends of the net are attached to a folding, multi-arm framework designed to expand and thereby spread the net after separation from the glider. The spreading action is initiated by an extraction parachute which pulls the first frame from the air vehicle. The spreading action is completed by the second frame which is coupled to a brake mechanism in the glider that maintains tension throughout the net to complete the spreading of the net.

Abstract: An aerodynamic vane is mounted on the fuselage of an aircraft for purposes such as sensing the angle of attack of an aircraft. The vane is attached to a fuselage mounting hub by means of a deformable hinge member and a weakened linear portion of the vane which is designed to give way under the force of impact of an object striking the vane. Should an object such as a bird strike the vane, the vane will separate from the hub along the weakened linear portion without the main body of the vane shattering. The hinge member, while it will deform under the impact, retains the vane to the fuselage so that it cannot fly into the engine or otherwise cause damage to the aircraft.
