An improved multi-purpose overland vehicle used for traversing dry land as well as snow, sand, and wet or marshy land, having an improved independent front suspension and steering system, with a mechanism for quickly exchanging front wheels for skis and vice versa, and a wobble boggie drive track support system, suspended by longitudinal leaf springs designed so as to provide maximum traction when traversing rough terrain and to elevate the rear idler sprocket mechanism of the track support asse...

Boron phosphate containing minor amounts of sulfate- and/or sodium-containing salts provides an improved dehydration catalyst for the synthesis of nitriles from carboxylic compounds or derivatives thereof and ammonia.

A disposable diaper of improved absorbency comprising a sheet of absorbent material folded into a multilayered structure in such a manner that a highly improved absorption effect is achieved while at the same time maintaining a garment comfortable to the wearer, and the diaper in combination with a diaper holder specially adapted to receive and hold the same.

Stability of viscous liquid hydrocarbon emulsions, wherein the hydrocarbon is present in a major proportion as the dispersed phase and emulsifiers do not represent more than 2 wt. percent of the total emulsion, is improved by the addition of certain dicarboxylic acid derivatives derived from reaction with amines and alcohols.

A facsimile system includes means to add or subtract control pulses or means to control a voltage controlled oscillator to provide for the proper visual orientation of the facsimile on the facsimile paper. The addition or subtraction of pulses may be accomplished manually or may be accomplished automatically using the phase detector to determine the proper orientation of the visible facsimile. The control of the voltage controlled oscillator may also be accomplished using a phase detector. The i...

In a miniature record player for reproducing diminutive records, there is provided a bifurcated tone arm, on the underside of which is formed a transverse slot. A U-shaped element is snapped into removable cooperation with the slot and slides therein to provide a velocity trip mechanism for the player.

A one-piece, molded, plastic clamp is formed of a pair of clamping members hingedly joined together so that the clamp is closed when the free ends of the members are urged together. The clamp includes a central opening generally symmetric about the hinge and extending into both members. The clamp is held closed by a progressive latch means having a T-shaped latch hingedly extending into the opening from one member for selective engagement by its cross portions with a pair of stepped keeper ramps...

The fabric fastener comprising two cloths adapted to engage with each other, wherein one of them is provided with the numerous mushroom engaging sections on its surface, while the other one is a two-ply cloth composed of two pieces of cloth combined by connecting strings and one of these two pieces is made to have numerous meshes in its surface.

Improved cascade apparatus for developing electrostatic images wherein a latent electrostatic image supported on a moving member is developed by cascading a flow of developer material including a magnetic component and an electroscopic component through a development zone. A chute receives a sufficient quantity of the developer material from a conveyor which moves the developer material in buckets from a sump and unloads a developer material at the inlet side of the chute. A magnetic member is p...

A last for shoe production. In that last there is defined a metartasal line being the line corresponding to that line of the foot sole connecting the joints which separate the metartasus from the phalanges. The last is characterized by at least one bulge at the metatarsal line region so designed that when the last is rested on a horizontal surface the toe portion remains clear of that surface while when the last is tilted by lifting the heel portion by the height of the designated heel, the toe ...
