Abstract: ABSTRACT OF THE DISCLOSURE     A flexible disc cassette is provided with a shutter which is capable of opning/closing a head access hole and a pad insertion hole respectively formed in upper and lower halves thereof.  A V-shaped torsion spring is used as the spring for biasing the shutter in the closed position.  The lengths of the linear arm portions integrally formed with both sides of the coiled portion of the spring are approximately the same.  Both tips of the arm portions are bent at approximately 90° so as to form the L-shaped hooks which has the same length and which extend in the opposite directions along the height of the coiled portion.          The L-shaped hooks are stopped by the shutter and the cassette case.

Abstract: X.21 Switching System Abstract A system is disclosed to provide X.21 in-band call establishment signaling in the data path of a data communication system in a satellite communications controller.  The system includes an X.21 signaling protocol between a data terminal equipment and the satellite communications controller on the terrestrial side and allows self-switched digital data port functions in lieu of associated voice port and line functions as practiced in the prior art.  An important aspect is that the signaling rate is the same as the line data rate.  At the start of the signaling state, the E input to the call processor is activated for the appropriate port.  Call establishment signals are then processed through the digital switch and an X.21 adapter to the system's control processor.  Finally the call establishment signaling has been completed and all data bits go through the digital switch and are transmitted to the digital interface.  At the end of the call the data port goes back to the first, idle state.

Abstract: SINGLE ADJUSTMENT PHASE RESOLVER WITH CONSTANT AMPLITUDE OUTPUT            Abstract A single adjustment phase resolver uses common voltage control in a dual inversely tracking bridged-Tee attenuator circuit to provide a variable relative phase displacement between two output signals whose amplitude levels are maintained equal and constant throughout the range of the phase adjustment.  The dual bridged-Tee attenuator is implemented using two variolossers wherein the PIN diodes are serially connected in two pairs and the pairs are oppositely poled from one another.  An automatic gain control circuit adjusts the input signal level to compensate for a latitude of discrepancy between the inverse tracking variolossers.

Abstract: TITLE: VERTICAL VIBRATOR     Abstract of the Disclosure A  self lubricating industrial vibrator for  applications requiring  vertical  installation.  The vibrator  comprises  a rigid  generally  cylindrical housing in which  an  elongated, rotatable   shaft  is vertically, coaxially  received   for rotatable  displacement  by an external  conventional   motor.          Eccentrics  secured  on  opposite ends of  the  shaft  provide vibration, and the shaft is operationally secured for rotation within suitable bearing structure.   An oil passageway is thus defined interiorly of the bearing casing,  at opposite ends of the  internal  shaft between upper and lower  annular  bearing caps.   A  first lubricating oil reservoir is disposed  within the bearing housing in fluid flow communication with a portion of the  lower  shaft,  and the shaft  includes  an  internal, coaxially  defined  elongated bore which has been  internally, spirally grooved.  This  "rifled" shaft bore or interior draws lubricating  oil up and through the shaft and  distributes  it through  the  bearings  through suitable oiling  pathways  for continual  and  reliable  self  lubrication.  Additionally,  a rotatable, shaft-driven  impeller disposed within a second oil reservoir  outside of the bearing housing forces oil  upwardly through  the  shaft  bore  in cooperation  with  the  rifling, whereby to effectuate oil flow communication between the first and second oil reservoirs.

Abstract: ABSTRACT     A collapsing frame for collapsing an extruded tube of plastics material to flattened form employs two converging frame members each having a large number of parallel rows of rollers mounted with their axes of rotation transverse to the direction of movement of the tube.  Each row consists of a large number of small diameter, short length rollers of low density material mounted closely side-by-side to provide a continuous engagement surface, but freely rotatable independently of one another on the common axle.  The rollers are of low friction, high temperature resistance material such as polytetrafluorethylene or nylon.   The new frame results in better surface appearance owing to absence of scratches and reduction of wrinkling, and better tracking of the tube through the frame.  There is also an unexpected improvement in flatness believed due to better support of the tube.  An unexpected increase is possible in the rate of extrusion and speed of movement of the tube, due partly to avoidance of jerking contact of the hot sticky film against the frame, but the increase obtained is not fully explainable by this and it is at present believed there is an increase in cooling of the tube, owing to the high heat exchange and air turbulence provided by the large number of individual spinning rollers.

Abstract: POSTER AND ITS MAKING METHOD                 Abstract of the Disclosure Disclosed is a poster comprising a white base sheet and a plurality of parallel black stripes of so various widths that they are in conformity with the values in the light or dark tones in an original picture, thereby mixing black and white lines so as to cause a desired halftone picture to appear.  The parallel stripes of various widths are formed by means of a computer-assisted cutter.  Its cutting tool is moved in an adhesive black film in response to an electric signal representing the values in the light and dark tones in the stripe pattern of the original picture, thus cutting stripes of various widths in the black film.  Then, the black stripes of various widths are applied to the white background, mixing the black stripes and the resultant white stripes, and causing a halftone-like picture to appear.

Abstract: SUMMARY          Modern continuous casting techniques, especially those involving  higher    casting speeds, and  attempts  to optimize quality on the surface and in the centre of the semis obtained in this manner, call for very close con-trol of conditions during the course of operations. One of the basic parameters is the steel casting tem-perature, which must be kept within a very narrow range above the solidification temperature.   This  invention permits the casting  temperature to be controlled  and maintained within the optimum range and towards the low-est permissible values, through heating applied in the ladle and/or the  tundish as well as in the nozzle.
