Abstract: Electronic printer apparatus in which the intensity of the beam of a cathode-ray tube is controlled during successive beam sweeps to display and project onto a rotating electrostatically-charged surface an image of successive slices through a row of characters to be printed, the latent line images thus formed being then converted to a toner image for subsequent transfer to a page of paper. Digital information bits organized in bytes and representing slices through each character are stored in respective areas of a permanent memory storage device. The appropriate slices of the characters are accessed in response to character-representing input signals, and are read out serially to control the beam intensity during each sweep and thus display, along the sweep, the desired slice through the row of characters.

Abstract: A stay mechanism for two hingedly connected members which are moveable between a first unengaged position and a second engaged position. An arm is hingedly attached at one end to a first member. The other end of the arm has a protrusion which is resiliently held in the pocket portion of a resilient strip attached to a second member, when the members are in the second position. A camming surface, facing the pocket of the resilient strip, defines, with the pocket, a resilient enclosure for the protrusion. The protrusion may be forced to slide out of the enclosure when the two members are moved towards the first position, by the resilient deformation and opening of the pocket. The resilient strip also has an inclined portion adjacent the pocket portion which serves as a guide for the protrusion into the pocket, when it is desired to move the members from the second position into the first position.

Abstract: A fluid actuated switching system is disclosed which comprises a fluid actuated poppet mounted in a fluid passageway for movement from a first position in the absence of fluid flow to a second position in response to a predetermined fluid flow. An elongated permanent magnet element is mounted on the poppet for movement along the axis of movement of the poppet. A second magnet element is positioned exteriorly of the fluid passageway adjacent the first magnet element. The two elongated magnet elements are polarized so that like poles are adjacent to one another and repel the two elements when the flow actuated poppet is in the first position and attract one another when the flow actuated poppet is in the second position, thereby moving the second magnet element with a snap action from one position to the other. The second magnet element actuates an electrical or pneumatic switch.

Abstract: A hydroelectric generator is located in the basement of a high-rise building and connected in series in the clean waste-water line of the building, to produce electrical power in response to the flow of the waste water from the building. An automatically controlled valve in a bypass line serves to direct excess water flow around the hydroelectric generator unit and maintain the flow through the generator unit at a predetermined maximum level. An automatic switch-over device disconnects the generator output terminals from the electrical output terminals of the unit when the voltage and/or frequency of the generator output is unsatisfactory, e.g., too low.
