Abstract: An apparatus for measuring the amount of medication in a sealed metered dose inhaler dispenser comprises a housing in which a mounting platform is located. An aperture in the housing allows the dispenser to be placed on the platform. Displacement of the platform is correlated with the weight of the dispenser and contents. The weight is displayed as an indication of the amount of medication in the dispenser from full to empty. The platform means may rest on a compression spring, the deflection of the spring being correlated with the applied weight. Tabs associated with the platform align with indicia on the exterior of the housing to indicate the degree of dispenser fill.
Abstract: A panel having a suspending hook at a lower end thereof slidably receives an optimum-weight comparison chart. The hook is used to support a basket or sling in which a child is held for weighing. A spring-loaded limb overlies the panel, and has a stylus in an end thereof, with a second hook at the opposite end thereof. The second hook is used to suspend the panel from a tree branch, a beam, or such, and the weight of a child causes the panel to descend, against the biasing of the spring-loaded limb. The stylus is depressed to make a hole in the chart for comparison with an optimum trajectory of weight/development of children of like age, and to keep a record of the measured weight, and to track weight gain or loss with successive weighings and stylus hole-punching of the chart.

Abstract: A combined fastener and tension indicator means employed for securing the ends of a band having undulations formed therein. The band is employed for retaining insulation panels which have been applied over the exterior surface of a structure to be insulated thereby. The structure to be insulated is caused to expand and/or contract depending upon the surrounding atmospheric conditions. A tension is applied to the band to insure the band always being in close contact with the exterior surface of the structure to which the panels have been applied. The undulations formed in the band together with the amount of tension applied to the band will permit for the structure to which the panels have been applied to expand and/or contract while still retaining the insulation panels in close contact with the exterior surface of the structure to which the panels have been applied.
