Abstract: ABSTRACT OF THE DISCLOSURE:     Method for the renewal of the tread of a worn pneumatic or solid rubber tire.  It consists in:  applying a layer of bonding rubber to the exterior of a prepared tire body; imparting a very hard stretch to a prefabricated precured rubber tread ring to such an amount that its inner diameter is much greater than the diameter of the tire body to which it is to be applied and the tread rubber plastically deforms longitudinally to an extent that, upon being freed from the stretching forces, the tread rubber gradually reduces longitudinally down to a point of retaining a residual permanent stretch; freeing the tread ring from the forces employed in imparting the stretch; placing the freed previously stretched tread ring over the tire body while the tread ring that was very hard stretched to a large diameter retains temporarily an inner diameter greater than and in the range of the diameter of the tire body; leading away gaseous inclusions between the tire body and the tread ring, and heating the assembly of the tire body and the tread ring to vulcanize the layer of bonding rubber between the tire body and the tread ring.

Abstract: METHOD AND APPARATUS FOR FUEL ECONOMY            Abstract of the Disclosure There are disclosed means and method for improving the efficiency of combustion in an automatic gas-fired furnace through retardation, without restriction, of the exhaust emission of the products of combustion, which are caused to dwell longer in the combustion chamber to elevate the temperature, not only through the impound-ment of what would otherwise be waste heat, but by the conversion of CO gas and excess air to CO2 gas, thus, reducing the two former, increasing the latter, along with temperature.  This reduces the condensate in the exhaust chimney.  An enlarged chamber in the exhaust gas conduit is incorporated within and beneath the line of exhaust flow from furnace to chimney.  A baffle plate, approxi-mately equal in area to the cross-sectional area of the conduit, is immovably secured in the top of the chamber normal to the line of exhaust flow.  The chamber is completely closed except for the exhaust flow entry and exit ports.  The chamber affords clearance beneath or around the baffle for the unimpeded passage of the exhaust gases equal in area, or greater than, that of the exhaust gas conduit.

Abstract: INVENTOR: HANS-ULRICH STAUBER     INVENTION: APPARATUS FOR FORMING STACKS FROM CONTINUOUSLY            ARRIVING FLAT PRODUCTS, ESPECIALLY PRINTED PRODUCTS, PARTICULARLY THOSE ARRIVING IN A LAPPED OR IMBRICATED STREAM                 ABSTRACT OF THE DISCLOSURE     Below a stationary stacker device there are arranged two movable prestacker units which are movable out-of-phase between a receiving position and a delivery position.  Within a stacker chute of the relevant prestacker unit which is located in the receiving position there is formed from the incoming printed products a partial stack.  This partial stack reposes upon an elevationally displaceable support table.  In the delivery position, by raising the support table, the partial stack lying thereon is displaced from below into the stacker chute of the stacker device.  This stacker chute is closed at its bottom end by pivotable restraining or retention flaps which are pivotable about bearing shafts.  The restraining flaps are pivoted back out of their effective position by the introduced partial stack.  The restraining or retention flaps are elevationally displaceable and receive the partial stack which is to be introduced from the support table located in its upper end or terminal position and, during their displacement movement, convey the engaged partial stack completely into the stacker chute.  Both of the prestacker units are arranged upon a rotatable support arm and are situated, with respect to a pivot journal or pin of such support arm, opposite one another.  The one prestacker unit is fixedly connected with the support arm, whereas the other prestacker unit is rotatably mounted in the support arm.  A sprocket wheel is fixedly connected with this second prestacker unit.  The sprocket wheel is drivingly connected by means of a chain with a second sprocket wheel which is keyed to the pivot or bearing pin.  Upon rotation of the support arm through 180° the pre-stacker unit fixedly connected with the support arm rotates about the bearing pin, whereas the rotatable prestacker unit rotates about its vertical axis, and thus, performs a trans-latory movement between the receiving position and delivery position.  As a result, the partial stacks are stacked upon one another in a crosswise position with respect to the final stack.

Abstract: ABSTRACT OF THE DISCLOSURE Apparatus for preventing two switches from being simultaneously closed. A pair of rollers are each movable in, and between the ends of, respective curved tracks. The rollers are each links to a respective switch so that when its switch is closed, each roller is at the bottom of its track, and when its switch is open, each roller is at the top of its track. Each switch cannot operate if the roller cannot move. A yoke maintains the rollers a fixed distance apart so that each roller may be at the top of its track, one roller may be at the top of its track while the other roller is at the bottom of its track, and vice versa, but one roller cannot move away from the top of its track if the other roller is not at the top of its track and vice versa. If one switch attempts to close while the other switch is closed, the roller of the closed switch is pulled into a detent at the bottom of its track; the roller remains in the detent as long as the other switch attempts closure. The closed switch may reopen while its roller remains in its detent, preventing closure of the one switch until its attempt at closure ceases. If the switches attempt simultaneous closure, one roller is preferentially held at the top of its track while the other roller moves to the bottom of its track.
