Abstract: ABSTRACT  A heat exchanger which comprises extremely flat oval-shaped tubes extending in a mutuallly parallel and spaced-apart relationship and are connected on their narrow side to manifold pipes for forward and return flow.  To ensure a sufficiently stable mechanical connection between the pipes and a satisfactory supply and discharge of the heating medium from the manifolds to the flat tubes as well as in the reverse direction, a trough is formed by material removal in the manifold pipes thus creating a connection aperture in the wall of the pipe.  The flat tube is fitted into this trough with its rim on the narrow side, to ensure a solid stable welded joint between the pipes.  The flat tube is provided on its narrow side with a bore serving as a connection aperture which comes to lie centrally against the connection  aperture in the manifold.  A trough in the flat tube and a bore in the manifold pipe or a respective trough in the manifold pipe and in the flat tube could be developed as alternatives.

Abstract: ABSTRACT OF THE DISCLOSURE     The combination of a continuous plastics film and a container therefor, the film being partitioned into a multiplicity of sections, each section of which is of a bag form or a sheet form.  In this construction, the plastics continuous film is folded in such a manner that linear cuts formed in the plastics film are superposed one right on another.  The plastics film is disposed in the container in such a state that an insert member or members are inserted through the linear cuts thus superposed.  In taking out the film, an end portion of the film is drawn out of a film take-out opening to the outside, such that a section of film of a predetermined length is drawn out and cut off at a linear cut portion by means of the insert member or members, and, as the film is cut off, an end portion of the succeeding, i.e. second, film section is adapted to be automatically drawn out to the take-out opening by the action of the connected film portions flanking the linear cut portions, whereby the sections of plastics film contained in the container are easily and reliably taken out one after another in the same manner as in a pop-up take-out method applied to tissue paper.

Abstract: ABSTRACT OF THE DISCLOSURE     Method and apparatus for winding lengths of flexible material, packages produced by such method and apparatus, as well as endforms forming part of the mandrels on which such windings are formed, incorporate a number of winding parameters which are related to one another by a mathematical formula.          Specifically, the mathematical relationship ym = -   where:          A = the guide stroke, Gd = the guide distance from the spindle center line axis, G = the gain or advance of the wind, Dm = the diameter of the wind or coil, and Ym = the wind or coil width; governs the shape of the walls of the endform and such end-forms are used in winding apparatus for producing wound packages of flexible material.  From the above equation, the geometrical shape of the wound package can also be determined.

Abstract: ABSTRACT        A valve rod of a gas heating device actuates not only a microswitch, but also a disc valve.  A pilot burner and a main burner are separately controlled by individual solenoid operated valve which is serially connected.  The disc valve is provided at the upstream of the pilot burner, and between two solenoid operated valves for safeguarding against the erroneous on-state of the microswitch.  A sensor will, according to the presence of the pilot flame, instruct an electric control board to continue or discon-tinue the sparkling of an igniter, to open or closes the solenoid valve for supplying gas to the main burner.  Thus, the adversity of toxication caused by either the misfunc-tion of microswitch or failure of valve actuation is able to be prevented.

Abstract: DISTRIBUTED BEAM STEERING COMPUTER Abstract A  distributive beam steering computer network for a radar phased array antenna is disclosed which provides direct drive for individual antenna phase shifter elements using a plurality of microcomputers co-located with each phase shifter.  The microcomputers calculate the phase shift based on constants stored in a ROM which is located in each micro-computer and phase shift data comprising sin.alpha.  , sin.beta. , and 1/.lambda. signals are distributed to all microcomputers over a single serial data line.  The constants required for each shifter are different, and therefore, the ROM in each micro-computer is programmed for a specific location in an array antenna.  A phase shift steering command for each element of the phased array antenna is calculated using a shift-and-add multiplication algorithm which is hard-wired into each microcomputer.

Abstract: ABSTRACT         A safety device for controlling the flow of fuel to internal combustion engines so as to protect an engine against damage due to insuffient oil pressure in the lubricating system.  The device has a main body with a main fuel passageway therein and a main valve in the main fuel passageway controlling the normal flow of fuel between an inlet port and an outlet port, the main valve closing when a lubricant pressure sensor indicates that the pressure in the engine's lubricating system is below a predetermined value.  The device has a bypass fuel passageway operable to allow a predetermined restricted amount of fuel to flow from the fuel inlet port to the fuel outlet port, and having a normally closed bypass valve blocking the bypass fuel passageway.  The bypass valve actuator is located remote from the body of the main fuel passageway and includes a manually-operable pushbutton with means for locking the pushbutton in a position corresponding to the bypass valve being opened.  The device provides a remotely actuated non-electrical, simple and reliable override function for a fuel cut off arrangement.
