Abstract: ABSTRACT OF THE DISCLOSURE            A hydrostatic extrusion process and an apparatus there-for includes a mandrel and a stem which are movable independently of each other, and a seal block which is utilized for increasing the pressure of the pressure medium for performance of the extru-sion operation of the billet.  A supply device pre-disposes an extrusion die, a billet, pressure medium, and a seal block within a supply unit or sleeve and is capable of being moved from a position exterior of the extrusion apparatus station to a position corresponding to the extrusion station, and in this manner, the time period required for completing extrusion cycles is substan-tially reduced.  Still further, a locking mechanism, including a locking slide and a locking plate, are operatively associated with the mandrel for controlling or limiting the axial movement of the mandrel so as to in turn control the loading and tensioning of the same in order to prevent damage thereto.

Abstract: ABSTRACT            In a microfilm web handling apparatus wherein a photocell senses position markers corresponding to image frames along the microfilm web to enable positioning of a given image frame within a viewing station, a reference photocell provides a reference signal which is compared with a detected signal from the position sensing photo-cell to produce a position signal which is processed via logic networks to drive a film transport mechanism to thereby selectively position the microfilm web.  Pre-rerably, three photocells are provided, two of which sense position markers adjacent one edge of the microfilm web, while the third provides the reference signal.  Each photo-cell has an effective sensing diameter which is not greater than one-half the dimension of a position marker parallel to the direction of travel of the web.  In such an embodi-ment, the output of the reference photocell is compared with the detected signal from each of the two position indicating photocells.    The apparatus further preferably includes a transverse motion carriage to enable image frames located within either or two parallel tracks along the length of the microfilm web to be selectively positioned within a viewing station.  The transverse motion carriage and the direction of web transport are automatically controlled in response to appropriate input signals.

Abstract: OMNIDIRECTIONAL SPEED COCKPIT DISPLAY                  ABSTRACT OF THE DISCLOSURE         An omnidirectional cockpit display has perpendicular bars independently moving across a plate for providing indi-cations of speed in lateral, forward and rearward directions.          A zero point is centered between lateral edges of the plate and is displaced vertically from the center of the plate to provide greater speed indications in a forward direction than in a rearward direction.  A safe flight envelope is indicated on the plate, extending around the zero point in lateral and rearward directions and extending toward the edges of the plate in the forward flight direction.  Indicator scales are mounted along edges of the plate, and pointers move along the scales to indicate vector sum of component speeds, and density altitude.  Other scales and pointers indicate ground speed in orthogonal directions, while the crossbars indicate air speed in those directions.  Othe  peripheral scales and pointers indicate directional control position, collective thrust control position, rate of climb and rate of closure.  Vector sum or absolute magnitude is indicated at all times.  When the absolute speed exceeds the graphic capability of the display, the vector sum can be determined by viewing the pointer scale on the left side.  Safe rotor engagement and disengagement envelopes are presented as a shaded area on the plate.  On-off warning flags are provided around peripheries of the plate.

Abstract: ABSTRACT OF THE DISCLOSURE         A first contact arm on the minute shaft of a clock-work switches, once every 30 minutes, the mode of energization of an electronic gating circuit with two sectlons in the inputs of an inverting anticoincidence (NOXOR) gate working into a set-ting input of a flip-flop which controls the driving circuit of a striking mechanism, each section having two parallel branches of relatively inverting character and with a relative phase de-lay whereby any switchover results in a brief de-energlzation of that setting input and thus in a setting of the flip-flop.          A pulse generator, included in or energized by the driving cir-cuit, works into a stepping input of a binary pulse counter pro-vided with four output leads whose pattern of enerqization re-presents the numerical values from 1 through 12.  A logic net-work, connected to a resetting input of the flip-flop and to a clearing input of the pulse counter, discriminates between switch-overs at the full hour and at the half-hour in response to the state of energization of the gating circuit; on the half-hour, the flip-flop is reset and the pulse counter is cleared upon the energization of the No. 1 output lead of the counter, whereas on the full hour these events take place under the control of a second contact arm carried on the hour shaft of the clockwork whenever the pulse count matches the position of that contact arm.

Abstract: ABSTRACT    A solar heating panel provides for improved heat transfer between an absorber plate, which receives solar radiation, and tubes, which carry water to be heated, by clamping the tubes into channels formed in the absorber plate.  The clamping is effected through upper bar members acting on the top of the absorber plate, and thermally insulating material supporting the tubes and itself supported by lower bar members below the absorber plate. The lower bar members do not contact either the tubes or the absorber plate.  Advantageously, the upper bar members which contact the absorber plate, the absorber plate itself, and the metal frame members to which the upper bar members are secured are all made of corrosion resistant aluminium alloy.  The tubes used for carrying the water to be heated may also be made of a similar alloy.

Abstract: METHOD AND APPARATUS FOR MAKING DOUBLE GROOVE PULLEYS      ABSTRACT OF THE DISCLOSURE         An apparatus is provided for forming a pulley having at least two grooves from a cup-shaped metal blank having an axially extending sidewall.  The blank is rotated about its longitudinal axis and is crushed between axially closing dies.          As the blank is being crushed, an inner forming roll positioned within the cup is translated radially away from the longitudinal axis of the cup and into contact with the inner periphery of the cup.  A rough forming roll is translated radially into contact with the outer periphery of the cup and applies forming pressure at a location radially offset from the area of contact of the inner forming roll.  A finish forming roll is radially aligned with the rough forming roll and is translated radially toward the outer periphery of the cup.  The rough and finish forming rolls are carried by cam-actuated slide assemblies arranged to move the rough roll into the blank wall in advance of the finish roll in a working operation so as to partially form a pulley groove and to maintain the finish roll in the partially formed groove in an idling operation.  Thereafter, the rough roll is disengaged from the partially formed pulley groove and the finish roll is advanced to the root of the partially formed groove and into a working operation to form the finish groove against the inner roll.
