Abstract: ABSTRACT          Apparatus for cleaning pipelines of finite length has a four way flow reversing valve whose body admits a liquid cleaning agent from an inlet into one port and thence into a pipeline whence the cleaning agent flows back into the body by way of a second port and is discharged by way of an outlet.  The valving element is a piston which is reciprocable between two end positions in one of which the flow of cleaning agent takes place as outlined  above and in the other of which the cleaning agent flows first into the other port and returns into the body of the valve by way of the one port to be discharged by way of the outlet.  The body of the valve is separably connected with the larger-diameter end portions of two cylindrical housings whose smaller-diameter end portions are separably connectable with the respective ends of the pipeline.  A supply of cleaning elements, such as balls of sponge rubber, is used in the apparatus to automatically change the position of the piston as soon as they impinge upon the one or the other end of the piston.  The larger-diameter end portions of the housings are separably connected to the body of the valve by quick-release couplings which are actuated by hand, and one of the housings can be equipped with a shutoff valve so that it can confine therein a supply of cleaning elements as well as a body of sterilizing liquid medium wherein the cleaning elements are immersed when the apparatus is not in use.

Abstract: ABSTRACT OF THE DISCLOSURE           An electrical switch assembly having a first switch contact member behind a housing panel which has an opening through which the shank of a bolt extends.  The bolt shank carries a second switch contact member for engagement with the first switch contact member.  An enlarged head on the bolt has a flat rear face for engaging the front of the housing panel around the opening.  A rigid washer on the bolt shank is spaced slightly farther from the rear face of the bolt head than the thickness of the panel at the opening, so that normally the shank of the bolt tilts downward inside the housing.  This establishes a first position of the second switch contact member, which is on the bolt shank, with respect to the first switch contact member.  A person's finger pressing on the bolt head can raise the bolt shank to establish a second position of the second switch contact member.

Abstract: ABSTRACT     A local area network is disclosed including apparatus and methods for transferring data between a plurality of data processing resources ("agents") coupled to a cable.  In the preferred embodiment, a plurality of agents are coupled to a common cable for data transmission and reception.  An agent newly coupled to the cable dynamically assigns itself a unique address on the cable to which other agents may send data.  Once an agent has been assigned a final address, it may then transmit to, and receive data from, other agents on the cable.  An agent desiring to send data to a receiving agent follows a three step handshake, wherein the sending agent transmits an "RTS" signal and within a predetermined time must receive a "CTS" signal from the receiving agent.  The sending agent then transmits a data frame within a predetermined time after the CTS signal is received.  The failure to detect a return CTS signal within the predetermined time denotes a collision condition.  Re-transmission is attempted using a linear back off method which is adjusted based on previous cable traffic history.

Abstract: SIZE INDEPENDENT MODULAR WEB PROCESSING LINE AND MODULES     ABSTRACT OF THE DISCLOSURE     Modular web processing units may be physically and electrically assembled into clusters to perform various web processes (e.g. the production of paper forms such as invoices, checks, labels, etc.).  Each module has a main process driver which is not directly coupled to a web drive mechanism.  Rather, the web drive is program controlled so as to effect the desired web process at controlled displacement intervals along the web.  Accordingly, a plurality of successive but different form lengths or depths can be accommodated as the web surface is sequentially processed.  A system of such modules can be physically wheeled into position as individual units and electrically connected together by suitable umbilical cords to rapidly configure a desired overall web finishing process.  Nevertheless, the entire ensemble of modules performs as though it is a unitary special purpose web processing machine with its various process stations interconnected and synchronized by an electronic "drive shaft".  One of the modular units automatically becomes the master source of process drive pulses for the others and the entire ensemble may be controlled from the control panel of any one of the modules.
