Abstract: ABSTRACT OF THE DISCLOSURE     A wood-fired boiler ant hot liquid storage system includes a top-vented storage tank for the liquid, a firebox supported within the tank at a level for complete immersion within the liquid, with the bottom of the firebox spaced above the bottom of the tank, and with a firebox end opening in liquid tight engagement with the edges of a corresponding tank side wall opening, and a firebox door for selectively closing the opening and permitting introduction of solid fuel. Combustion gases from the firebox are discharged through an open vertical stack extending up through the tank and liquid to an outlet opening outside the tank.  Preheated combustion air is introduced at the firebox opening and fed by forced draft through the firebox and stack by a blower.          The preheating is provided by a special firebox door construction in which incoming air passes between inner and outer walls of the door and is preheated by the hot inner door wall while it also keeps the outer door wall at a lower temperature.  Other features include selectively usable off-peak electrical immersion heating elements, cylindrical tank and firebox cross sections, and special heat transfer means in the firebox and stack construction details.

Abstract: INFINITELY VARIABLE GEAR RATIO TRANSMISSION         Abstract of the Disclosure An infinitely variable gear ratio transmission includes plural cam followers driven to oscillate by a rotating cam.  The oscillatory motion of the cam followers is combined through plural clutches to provide an output drive. The cam includes at least one surface formed to rotate the cam followers at a constant velocity when the cam rotates at a constant velocity, thereby permitting the output drive to be smooth.  The cam is tapered from one end to the other to permit the gear ratio of the transmission to be varied in infinite increments by adjusting the position of the cam relative to the followers.  Means for manually or automatically adjusting the gear ratio is provided.  Increased gear ratios may be obtained by separating the physical location of the follower mounting shaft from the rotational axis of the follower arms.  A universal joint, formed to uniformly transmit rotational velocity, is included to connect the inclined follower shafts to the output drive.  The follower arms are oriented relative to the cam such that the chords of follower movement during contact of the follower with the constant velocity surface, at various gear ratios, are mutually parallel, and the chord of such follower movement at the highest gear ratio passes through the center of rotation of the cam.     An alternative embodiment of the present invention further includes cooperating clutches which permit transmission of unidirectional shaft rotation between an input shaft and an output shaft regardless of the direction of torque applied to the shafts.

Abstract: ABSTRACT          "A METHOD OF AND SYSTEM FOR SAFEGUARDED        TRANSMISSION OF DIGITAL SIGNALS"            In order to achieve a higher resistance to inter-ference in respect of alien sources of deliberte interference in the use of short wave communications connections, the following cooperative measures are proposed.          (a)        The stations are equipped with highly accurate quartz crystal clocks QH and the bursts (Be, Br) which are to be transmitted are accompanied by a time signal (ZC) with the aid of which it is possible to correct any time dis-crepancies between the stations.          (b)     Employing an automatic response arrangement (ARQ), use is made of a variation in the timing of consecutive burst transmissions including the acknowledgement response (RQ).          (c)        The error-protected data in the burst is trans-mitted in enciphered form.          (d)        The cipher sequence for the enciphering of the data component (IN) and the error-protection component (EDC) of the burst (Be, Bi) and for the frequency address which determines the transmitting and receiving frequencies is re-calculated for each burst on the basis of the clock time given by the quartz crystal clock (QH) and on the basis of the receiving subscriber number.

Abstract: ABSTRACT OF THE DISCLOSURE      Disclosed is a two level stacked press which provides for blanking and cupping in one section and drawing, redrawing and trimming in another section.  The reason for separating the various operations is in order to keep the overall size of the press compact. That is to say that, the cut edge diameter for the blank is the largest dimension of the piece part during the progressive forming operations.  If all of the operations were on one level in the press, the floor area for the press would be increased.  By blanking and cupping in one level and drawiing and redrawing in another level, the area of the press in plan can be minimized.  The area within the press required for blanking and cupping is as great as that for drawing and redrawing.  Similarly, the strokings required for blanking and cupping are significantly shorter than the strokes required for drawing and redrawing.  Thus, the press can be split into two sections but still be driven by a common crank shaft housed in a common crankcase and supported on common bearings so long as crank throws are provided for the stroking required for blanking and cupping and for the stroking for drawing and redrawing.  Another advantage of the stack press construction is the ability to use one portion of the crank rotation to blank and cup and the other portion of the crank shaft stroke to draw and redraw.  Thus, the overall loadings on the crank shaft and the press members are balanced and minimized.

Abstract: ABSTRACT     The invention relates to a pipe fitting A, B, C, with a flange connector for joining at least two pipe ends of pipes that are arranged at an angle to each other.  These pipe fittings are suitable for assembling a pipe system of any form with branch pipes and/or curves.  The pipe system is suitable for assembly in the smallest space with short-radius curves, in any direction. According to the present invention at least one connector opening (1, 2, 11, 12, 13) of the curved fitting, comprises an annular edge flange (3, 4, 14, 15, 16). The flange projection and the concave curvature of the pipe fitting (A, C) are arranged so that a space remains for a clamp (F) to be installed on the flange (3, 4, 14, 15, 16).  This clamp presses one edge flange against a counter flange.  The outside configuration and the face of the edge flange are such that, not only is it possible to install a gasket between the faces but also, there is sufficient elasticity relative to the pipe mantle if the flanges are pressed together by the clamp (F).  For this purpose there is a groove to accommodate the seal and an annular channel in the base area of the edge flange in the face surface which serves as a nominal bending point. (Figure 10).
