Abstract: A tamper indicating closure including an outer cap and an inner liner which relies on relative movement of the outer cap and the inner liner during opening movement to indicate tampering of the container after it has been sealed for the first time, the relative movement being insured by a means which coact with the container to resist rotation of the liner and maintain the container in a sealed condition while the outer cap is being rotated in an opening direction. Once opened, the outer cap and the inner liner are maintained in a position for movement as a unit in both the opening and closing direction of the closure.

Abstract: A child-resistant and tamper indicating overcap for a pressurized container, such as an aerosol can, having a valve with an axially protruding discharge nozzle which must be depressed to actuate the valve for discharging the contents of the container. The overcap includes a valve guard slidable between a radially outer position in which a portion of the guard overlies the nozzle for preventing actuation thereof and an inner position in which the nozzle can be depressed. A removable tamper indicating tab is connected to the guard to prevent movement of the guard to an actuating position until it is removed. The overcap includes a resilient portion of the guard which biases the guard toward its outer position and which must be overcome in order to move the guard to its inner position and which returns the guard to its outer position when the guard is released.

Abstract: Apparatus for injecting coolant into the fuel-air mixture supplied to a turbocharged internal combustion engine in which coolant is stored in a reservoir that is connected to the outlet side of a turbocharger compressor and is pressurized during times that the turbocharger is generating positive pressures above a predetermined level. The pressure in the reservoir forces coolant to the inlet side of the turbocharger to cool fuel and injection is interrupted when the pressures are below that level and cooling of the fuel-air mixture is not required.

Abstract: A fish detecting system including a radio transmitter in a float attached to a fishing line and a receiver at a point remote from the line.

Abstract: A safety package including a container with a unitary screw type cap in which the container has a locking lug engageable with one of a plurality of ratchet teeth located around the circumference of the cap. The ratchet teeth permit turning movement of the cap in a closing direction until the cap is squeezed and deformed at diametrically opposed points to move the engaged ratchet tooth out of engagement with the locking lug to permit turning movement of the cap to an opening position. A second locking lug is offset from a point diametrically spaced from the first locking lug so that one or the other of the lugs engages a ratchet tooth thereby doubling the effectiveness of the teeth.
