    摘要: A butterfly valve and associated controls for controlling the flow of water from a large diameter fire hose to the inlet of a fire pump is disclosed. The valve is installed between the suction tube and the suction tube extension of a midship mounted fire pump on a fire truck in a location such that the valve is positioned behind the pump operator panel. A pressure relief valve and an air bleed are mounted on the body of the valve.

    摘要: A device for collecting sebum which is secreted from the sebaceous glands of a subject includes a microporous, hydrophobic polymeric film which is opaque to light when the pores are filled with gaseous material and which is substantially translucent when the film pores are filled with sebum. The film is mounted to a substrate which includes a light absorbing area for enhancing visualization of the film pores when filled with sebum.

    摘要: A secure communication system for transmitting and receiving an encoded information signal. The system generates at transmitting and receiving locations a predetermined unique pseudorandom code. A synchronized tracking signal is imposed on the information to be transmitted and added to the information to form an intermediate signal. The pseudorandom code is then multiplied by the intermediate signal directly so that the ultimate result appears to assume the character of pseudorandom noise, which is then transmitted to the receiving location. The synchronization and transmitted encoded portion is decoded at the receiver and used to generate a base signal for a pseudorandom generator at the receiving location, as well as initiate initial clocking pulse time for operation of the receiver pseudorandom generator. The receiver then generates the predetermined pseudorandom code and divides the same against the encoded signal being received to form an intermediate signal having no pseudorandom signal component, which is then filtered to remove the tracking and masking signal and thereby generating the original information signal desired.
