Abstract: By providing a securely locked product dispensing valve assembly mounted to a product bearing container which requires a specially constructed cooperating adapter for opening the valve assembly, a controlled dispensing system is realized which provides complete controlled distribution of any desired chemical product. By employing the present invention, only authorized personnel are able to open the container incorporating the valve assembly, enabling the contents to be transferred into only suitable containers incorporating the required adapter for unlocking the valve assembly. As a result, control over the distribution of the chemical product is attained and a completely closed loop, spill-free system is realized. In addition, a rinsing head is provided for being cooperatively associated with the product bearing container and valve assembly to enable complete cleaning of the container prior to recycling.

Abstract: A still camera includes a frame defining a planar film path and resiliently supporting a magnetic head module urged into engagement with an edge of an associated film on which magnetically recorded information is to be applied. The module includes a head carriage restrained against longitudinal motion and carrying a pressure pad in opposed relation to a recording head mounted on a spring beam of the carriage so as to urge the head against a film backed by the pressure pad. The head module may be formed as a preassembled subassembly. A leaf spring supported by a tab held in the camera frame urges the module against the film edge.

Abstract: A camera locks out an attempted flash photograph when the voltage of the flash charger is below a minimum voltage necessary for the flash to fire. Flash lockout may also take place when: the flash charger voltage is equal to or greater than the minimum flash voltage but less than the lowest voltage in a voltage range providing optimum flash lighting; and the photographic subject distance is beyond the flash range at the present flash charger voltage. Lockout may also be determined based on current flash charger charging time compared to predetermined times for the flash charger to reach the minimum voltage and/or the lowest voltage in the optimum lighting range from a substantially discharged state.

Abstract: By employing two independent, separate and distinct flow paths which are controllably sequentially opened during use in a single actuation operation, an error-free, spill-free flame and explosion proof liquid delivery/filling system is achieved. In the preferred embodiment, both flow paths are normally maintained in a closed, sealed configuration, requiring an actuation force to controllably, sequentially open the flow paths. In addition, by providing a cooperating, mating liquid transfer assembly, the container on which the liquid delivery/filling system is mounted can be refilled with safety and ease, completely eliminating spillage of the liquid. In this way, a fully integrated, cooperating, liquid flow controlling system is realized. Furthermore, a process for distributing toxic chemicals is disclosed which provides full control over the chemicals being distributed and prevents unwanted spillages, misuse, and mishandling of the chemicals in an unpressurized, gravity fed system.

In the preferred embodiment, both flow paths are normally maintained in a closed, sealed configuration, requiring an actuation force to controllably, sequentially open the flow paths. Furthermore, the preferred embodiment is compact in design and provides an easy to use system, without sacrificing its inherent benefits. In addition, a flow diverging structure is mounted in the liquid flow path to assure complete removal of all of the air from the chamber being filled.
