Abstract: A liquid level indicating device for a fuel tank adaptable for use in any size fuel tank comprising a mounting plate, a support arm depending therefrom, a float arm, a float, a linear wire-wound resistor, a sliding contact member, a device for varying the angle of tilt of the float arm, a device for varying the distance of the arc through which the float sweeps relative to the support arm, and a device for adjusting the effective resistance range of said resistor by controlling the length of travel of the sliding contact member along the linear wire-wound resistor.

Abstract: The present invention provides a method for inhibiting corrosion and elastomer swelling and degradation caused by alcohol and alcohol-containing fuels and for increasing lubricity of alcohol or alcohol-containing fuels, comprising the step of adding to alcohol or alcohol-containing fuels, a fuel additive comprising one or more reaction products of a carboxylic acid or acid chloride selected from the group consisting of unsubstituted aromatic carboxylic acids, aliphatic carboxylic acids, nitro-substituted aromatic carboxylic acids and their corresponding acid chlorides, and an amine selected from the group consisting of aliphatic amines, cycloaliphatic amines, and aromatic amines.

Abstract: Disclosed is a microcomputer communications software implementation for controlling the transfer of data between a microcomputer and a host mainframe computer in various modes of operation, including an unattended mode, a terminal emulation mode, an automatic mode, and a manual mode. The present invention is particularly suitable for use with cash management systems.

Abstract: A hidden drawer arrangement for a cash transaction cabinet. A drawer is mounted in slide-out fashion in a compartment of the cabinet. A plain face panel on the drawer extends the width of the compartment to have the appearance of an immobile structural element of the cabinet. A latch arrangement is provided on the bottom of the drawer and is hidden by a lower section of the drawer face panel extending below the plane of the drawer bottom.

Abstract: A holder is provided for microfiche or other types of flexible sheets. The holder comprises a generally rectangular body having first and second major walls supported in substantially parallel relation to define a cavity therebetween in the body. A slot is formed along one side of the body extending between the first and second major walls through which microfiche enters and exits the cavity. A labyrinth-type lock is provided for retaining microfiche in the cavity, consisting of a projecting lip adjacent the slot on the first major wall and a ridge positioned inwardly from the lip on the second major wall. An opening is formed in the first major wall opposite the ridge to permit microfiche in the cavity to be contacted through the opening and guided around the ridge and the projecting lip for removal.
