A portable hand-held compass for taking navigational bearings on distant objects during the day or at night. The compass has a hollow housing in which a compass card is mounted for rotation about a vertical axis, a viewing window in the housing through which compass readings are taken, and a sighting barrel incorporated in the housing for viewing a distant object along a horizontal viewing path. The compass also has a manually activated light emitting diode for illuminating a reticle, a semi-ref...

A device for exercising the lower torso and legs including a rotatable platform and a pair of foot pedals rotatably mounted on the platform. Locking elements are provided to selectively and individually lock the platform or either pedal against rotation. Each pedal is mounted off center on a rotatable adjusting disc for varying the distance between the pedals.

Rocker attachments for converting a stationary folding lawn chair into a rocking chair including a spaced pair of arcuate tubular rocking elements which are transversely interconnected by beam structures which are demountably attachable to the chair. The beam structures are demountably connected to the rocker elements for storage and shipping purposes and are movable on the rocker elements to accommodate various sizes of lawn chairs.

The pedal driven swivel toy provides a ride for children which includes a combination of translation and rotation. The toy is suspended from a support structure allowing swinging and rotating motion. A wheel contacting the ground and driven by the child through the use of pedals forces the center of gravity of the toy from a stable rest position to an unstable position thereby inducing rotation and swinging of the toy. The combination of motion is exhilarating for the child and the use of pedals...

This invention relates to sealing compositions and, more particularly, sealing compositions for use in conjunction with tail seals of tunnelling machines. In particular a sealing composition according to the invention comprises, by mass, from 10 to 55% of a petroleum-derived wax, or wax-consistency hydrogenated vegetable oil or fat, or a polyisoobutane of oil, grease or wax consistency, or any combination of the above, from 0.5 to 15% of a lipophilic emulsifier, and water in sufficient concentra...

A merry-go-round having seats for both riders and children who want to propel the merry-go-round with a pair of crank mechanism that are offset to ensure that their is no "dead spot" to make start up of the merry-go-round difficult with the merry-go-round including a pair of pivoting handles for children to propel the merry-go-round with octagonal shaped circumferential seating and foot support areas to support the children's feet above the ground and a pair of safety hand rails for riding child...

A riding capsule device includes a capsule member, a base, and control mechanism. The capsule member has a bottom configuration in the form of a convex spherical segment. The base has a lower portion with a top configuration in the form of a concave spherical segment engaged by said bottom configuration of the capsule member and having a radius of curvature which is larger than the radius of curvature of the bottom configuration of the capsule member. The base further has an upper portion with a...

Magnetic compass bearing attachment devices for use as a separate entity and either with or without binoculars or the like for selectively and temporarily holding the bearing of the compass rose or card, after an object or target sighting has been made therewith. The devices are purely mechanical and include a weight-activated, pivotally mounted bell-crank lever system of which the weight, responsive to respective front and back tilting of the device during use, moves the card clamping end of th...

A directional device for overland travel to aid in returning to intersect a roadway, in which a pair of concentric rotatable dials and a freely rotatable compass needle are mounted on a frame. One dial carries a first reference indicium while the other dial is divided into a pair of individually identifiable semicircular arcs having a reference divider at one junction of the arcs. The dials are releasably fixable one with respect to the other and the one dial is releasably fixable with respect t...
