A front plate sandwiches one end of the blade between it and the back plate. The front plate is adjacent the back plate rather than spaced therefrom.

Abstract: A controlled release wall structure is provided which relies on controlled strength distribution and which disengages from a building framework at a selected applied load -- failure load -- and collapses in the direction of the applied load, that is, inwardly or outwardly of the building. Under normal wind load conditions, the present wall structure will safely sustain the expected elastic deflection and working stresses. However, under abnormally high loadings such as applied by explosion forces or by tornado and hurricane wind forces, the present wall structure collapses to create a substantial open area whereby a minimal loading is transmitted to the structural framework. The present wall structure protects the building framework from being overstressed during tornadoes or hurricanes; and also is capable of quickly relieving excessive pressures generated by an explosion within or without the building.

Abstract: An arrangement for correcting an electronic timepiece comprises a normally reset flip-flop that holds, when set, a "second" counter in a reset state. When a first switch is closed after being released, the timepiece cyclically gives a normal, a "minute," and an "hour" indication. While a "minute" indication is given, a second switch is closed to set the flip-flop and advance a "minute" counter. When the second switch is released after the "minute" indication is advanced to a correct time, the "second" and "minute" counter are kept still. When the first switch is closed at the correct time after being preliminarily released, the flip-flop is reset to restart the watch with correct "minute" and "second" indications. The arrangement enables the correction to be carried out once again. While given, an "hour" indication is corrected by the second switch.
