Abstract: Abstract of the Disclosure A device protects a structure against the effects of high hori-zontal dynamic stresses.  A system of friction supports is constituted by seating blocks applied against each other and incorporated respectively with the structure and with the foundation floor.  A relative displacement with friction is permitted between the associated blocks along their mutual bearing surface.  The coefficients of static and dynamic friction of the con-tact surfaces range between a minimum of 0.08 which is compatible with the permissible displacements of the structure as a function of the structural connections and a maximum value of 0.5 which is compatible with the threshold value of inherent resistance of the structure.  The area of one of the fric-tion surfaces of the blocks projects to an appreciable extent with respect to the area of the adjacent surface.  The friction supports comprise at least one elastomer block in series with the friction surfaces.

Abstract: HOT GAS ENGINE ABSTRACT:    A multi-cylinder self-starting hot gas engine consists of two parallel pairs of opposed dis-placer cylinders with respective displacer members mounted for movement therein and two parallel pairs of opposed work cylinders disposed parallel to the displacer cylinders and having respective pistons arranged to reciprocate therein; each work cylinder communicating with a respective dis-placer cylinder to provide a cold end chamber.  An output drive is connected to the pistons.  First and second trans-mission means connect the displacers and pistons respective-ly for synchronized movement offset in phase within the respective cylinders.  An adjustable phase displacer inter-connects the first and second transmission means for ad-justing the phase relation of the displacers with respect to their associated pistons from an in-phase condition in which no torque is applied to or from the output drive to an optimum-phase displacement position in which the maximum torque is applied to or from the output drive.  A fluid heat source at the displacer cylinder hot end providing high heat transfer relationship between the gaseous medium and the heating fluid, so that when the engine is at rest with the displacers in the in-phase condition, movement of the displacers, in response to operation of the adjustable phase displacers away from the in-phase condition causes an immediate imbalance in pressure applied to the pistons to provide an immediate self-start.  Cooling means is provided at the cold end for cooling the gaseous medium therein.

Abstract: REVERSIBLE DRIVE FOR A FLEXIBLE WEB            ABSTRACT OF DISCLOSURE A reversible drive apparatus for a flexible web, especially adapted to a reversible ribbon drive for a printing machine. A driving spur gear is arranged to be shifted between a pair of spur gears, each associated with a ribbon spool. The shifting is accomplished by mere reversal of direction of a drive motor which has a lead screw type shaft upon which the driving spur gear is mounted with mating screw threads. This allows the driving spur gear to travel laterally along the lead screw shaft between the pair of spur gears whenever the motor reverses direction.

Abstract: "PLASTIC BREAD CARRIER HAYING FOLDING               END WALLS"                  ABSTRACT OF THE DISCLOSURE              The carrier comprises a tray having a floor and rails extending around its perimeter.  A pair of end walls are provided at the ends of the tray.  Each end wall is piv-otally connected to the tray so that it can be rotated from a horizontal position overlying the floor to a vertical position above the end rails.  The pivot connection also permits limited vertical movement so that the walls can be pushed down to engage the rails.  The lower portion of each end wall is formed of inner and outer spaced-apart legs which define a first groove extending the length of the wall.  The rail penetrates into this groove when the wall is lowered onto the rail so that the wall and rail are secured together.  There is also a row of abutments extending along the base of each end rail and spaced inwardly therefrom to form a second groove which is part of the tray.  The inner leg of each end wall seats in one of these grooves when the wall is lowered.          The legs and abutments cooperate to prevent each wall being rotated inwardly or outwardly when it is in the lowered position.  Releasable means are provided for restraining upward movement of the end walls relative to the tray when the end walls are in the downwardly shifted position.  The advantages:  Because the means securing together the end walls and tray extend across the width of the tray, forces acting against the end walls are resisted by the tray as a whole.          This has made it possible to make the carrier of plastic as forces are not concentrated at a small segment of the carrier.          Also the end walls are easily moved between stacking and folded positions.
