A chair base includes a vertical column from which radiate a plurality of legs each having a top plate and a caster-receiving socket adjacent its distal portion. An end cap is removably mounted about the socket while a separate integral scuff cap is slidably attached in an overlying manner to each leg and extends in an upward direction to overlie a portion of the base column.

A supporting base for a sharpening stone consisting of an elongated downwardly facing channel having downwardly inclined end portions presenting sharp corners at their bottom ends adapted to penetrate the surface of a work bench. The channel has a pair of spaced upstanding stops along one longitudinal margin, an upstanding fixed transverse stop at one end and a slidably adjustable upstanding transverse stop at its other end, so that sharpening stones of different lengths may be accommodated, bet...

A base mounting for an instrument or machine which has to be panned and/or tilted, the mounting incorporating a lock mechanism comprising a plurality of balls acting on brake rods.

1. A hollow projectile having an explosive charge therein, said projectile having a rearwardly facing portion with an aperture formed therein, a closure plate for said aperture, a proximity fuze carried by said closure plate and including an oscillator and an antenna in the form of a conical structure projecting rearwardly from said closure plate, mounting means on said closure plate for supporting the remainder of said proximity fuze within said hollow projectile, and connecting means including...

An electric lamp having a contact base, and a contact base for said lamp, the base having a metal shell closed at one end by a glass plug with a hole at its apex through which a lead-in wire can pass, a metal cylinder being fitted to the plug over the lead-in wire to be the center contact.

A knocked-down pedestal display base capable of being set up with one securing means including a central member, two pairs of similar legs, each leg including a vertically disposed section and an outwardly extending foot section, the vertically disposed section of one pair of legs being adapted to be secured to the central member and aligned in the same plane, the second pair of legs including lugs adapted for securing one end of the vertically disposed sections of the second pair of legs to the...

A base for a bed comprising (preferably two or four) light-weight thermoplastics platforms interlocked together by couplings which engage skirts and lugs depending from the platforms so as to prevent rotation of one platform relative to another. The platforms are easily separated for transport by a vertical lifting force yet they resist separation by unintentional rotational forces caused by sitting on or lifting their peripheral edges.

A base for the spar, i.e., mast, of a wind-propelled vehicle useful for attaching the spar, i.e., mast, to the universal joint which universal joint is further attached to the wind-propelled vehicle. The base has a cylindrical bore for receiving the spar, i.e., mast, in the upper portion thereof and the lower portion has an axially-located bore for the passage of a bolt which connects the lower end of the spar, i.e., mast, to a portion of the universal joint, and two line passages extending thro...

A magnetic base adapted to be secured to a magnetic substance attractively, wherein a permanent magnet 20 having a small reversible permeability .mu. is employed as a rotary magnet housed in a magnetic block 18 and rotated for switching magnetic active surfaces 24 of the block from an unexcited state to an excited state, thereby effecting a light and smooth rotation.

An ointment base for external use is provided which contains a water-soluble protein and monohydric alcohol or/and oleginous substance and additionally contains a wetting agent. The present ointment base offers a markedly improved percutaneous absorption of drugs, as compared with the conventional ointment bases.
