The device comprises (a) a pile of insulated plates separated by electrically conducting sheets, each conducting sheet being connected to a power source, and (b) a set of electric bulbs, each comprising a stem formed of two laterally protruding conducting parts insulated from each other and provided to be connected each to one of the conducting sheets through penetration of said stem in said pile.

Apparatus is illustrated for laying out indicia patterns and the like on a workpiece such as a wide flange beam wherein a pattern plate is carried in superposed relation to the flange of the wide flange beam by suitable frame members which also carry means for maintaining the pattern plate in longitudinal alignment with the flange, including a pair of opposed depending arms pivotally carried intermediate their ends with threadable means interconnecting upper end portions of the arms for adjustab...

A dough dividing and circular kneading device is spaced longitudinally from a dough rolling-out station with conveyor means carrying kneaded dough pieces from the dividing and kneading device to the rolling out-station. An endless conveyor extends between the rolling out-station and the kneading device, and has carrier elements thereon tiltable about respective pivot axes spaced longitudinally of the conveyor and extending transversely of the direction of movement of the conveyor, the carrier el...

A device for use in performing isometric exercises having a handle and a weight at one end of the handle offset from the longitudinal, turning axis of the handle. The handle defines a plurality of grasping positions for varying the effective torque of the weight relative to the user's hands. The mass of the weight is selectively adjustable.

An inclinable exercise bench is provided with a motorized bar positioned laterally above the bench so that a user reclining on the bench may grasp it. The bar is oscillated in a generally fore and aft direction allowing a user holding it to be raised to a sitting position on the bench. The user then returns to a reclining position and the bar is again moved forward providing continuous exercise.

An exercising device comprising a ladder and a frame pivotally mounted within the ladder uprights wherein the frame has rollers with vacuum cups for massage purposes including a manual crank for rotating the rollers while the user is resting on the frame rollers.

A device for mixing test reagents comprising a curved, concave test surface rotatably mounted on an inclined support is described. The reagents are mixed in the cavity of the concave test surface with a predetermined circular motion which results in uniform mixing of the reagents.

This invention concerns the separation and extraction of the upper layer of liquids stored in tanks or pools. The device consists of a shallow funnel, submerged in the liquid and equipped with means with draining off the extracted liquid, and characterized by the fact that the level of submersion, governing the amount of liquid drawn off, is regulated by a set of floats, which are either ballasted or adjusted in height, possibly by remote control. The main applications of this appliance are in t...

A simple, durable, inexpensive educational device for demonstrating properties of motion to children is described. The device comprises a horizontal stationary elevated support means which is a sandwich configuration of two rigid board members kept apart by spacing elements; a first string suspension means movably disposed about the spacers in the support means; and a second string suspension means connected to the first string suspension means. Both string suspension means are so coupled to one...

An automated capping machine is provided which seals heat shrinkable film about the mouth of an open container. The machine has a pneumatically operated drive system which is actuated by container placement. On actuation, heat shrinkable film advances to a cutting and shrinking position and the container is raised to meet the film. Movement of the cup brings the film against a hot wire cutter and advances the film-cup combination to a heat shrink station. The heat shrink station is designed to p...
