Abstract: Design optimization methods can be used to design concrete mixtures having optimized properties, including desired strength and slump at minimal cost. The design optimization methods use a computer-implemented process that is able to design and virtually “test” millions of hypothetical concrete compositions using mathematical algorithms that interrelate a number of variables that affect strength, slump, cost and other desired features. The design optimization procedure utilizes a constant K (or K factor) within Feret's strength equation that varies (e.g., logarithmically) with concrete strength for any given set of raw material inputs and processing equipment. That means that the binding efficiency or effectiveness of hydraulic cement increases with increasing concentration so long as the concrete remains optimized. The knowledge of how the K factor varies with binding efficiency and strength is a powerful tool that can be applied in multiple circumstances.

Abstract: The present invention relates to a credit card comprising a card body, which comprises fingerprint reading means providing fingerprint signals representative of at least one fingerprint from a card user, when at least one finger of said user is pressed against said fingerprint reading means. Said card body further comprises data carrier means holding at least card owner fingerprint data and secured data, and fingerprint authentication means for activating said secured data. The card body further comprises an electrical power supply delivering electrical current to at least said fingerprint reading means. Accordingly there is no need for an external electrical power supply, and thus the existing standard card reading systems, such as ID-card readers, money transfer machines such as ATM's and the like may be used in conjunction with said credit card. Thus, investments into new standard reader systems are not necessary in order to improve the security of the secured data carried by the credit card.

The securing track (11) is formed in a profile (27) embedded in the sandwich structure so that a securing track (11) extends at a right angle to lateral edges (14) of the covering plate (5). As either end of the profile is provided with tracks (29) for receiving tight-fitting pins (30), a floor structure can be mounted easily and rapidly.

Abstract: The invention relates to a toggle type snap switch having an operating arm and a switching arm with a toggle spring hingedly connected between these arms. In one embodiment of the invention the toggle spring is in the form of a plate with a window in one end thereof. The switching arm has separate, relatively moveable snap arm and switching arm sections and a hinge connection is provided between the toggle spring and the switching arm section. The window in the toggle spring has upper and lower edges alternately abuttingly engageable with the free end of the snap arm section for opposite snap positions of the operating arm. The window may have laterally extended slot sections to form a part of the hinge connection between the toggle spring and the switching arm section.

Abstract: The invention relates to a refrigeration assembly and particularly to defrosting apparatus therefor. The assembly includes a bellows operated thermostatic motor switch responsive to evaporator temperatures for operating the compressor motor. After a predetermined number of operating cycles of the compressor the defrost apparatus is actuated. There is a linkage between the bellows and the motor switch with a main spring acting thereon to oppose the bellows and a differential spring acting thereon to assist the bellows. The differential spring is made inoperative by the defrosting unit during the defrost setting. The main spring and the differential spring are calibrated so that when both springs are effective the motor switch is actuated at a predetermined evaporator temperature. When only the main spring is effective during the defrost setting the motor switch is actuatable at an evaporator temperature higher than the above referred to temperature.
