Abstract: ABSTRACT           An ice-resistant ocean structure comprising in combination a.  vertical support means having one or more vertical members, b.  one or more screw means rotatably mounted on one or more of said members, wherein the axis of said member and said screw means are congruent or parallel, c.  means for rotating said screw means, d.  helical blade means on said screw means so adapted and constructed as to move ice abutting said member to fail said ice in flexure.     In its most generic aspect the invention herein can be viewed as comprising structures having improved ice-contacting means for heavy ice which is covering navigable water.  These structures act upon the ice, causing the ice to fail in flexure.  Processes based on such means are also within this generic concept.  The preferred ice-contacting means is a screw means having a relatively large length-to-diameter ratio.  However, for some embodiments of the invention, other types of ice-contacting means are satisfactory. In another aspect, the invention provides a method of protecting an ocean structure having a vertical support member from the force of ice floes which comprises providing such member in contact with said ice floes with a vertically mounted screw means having a.  a helical blade means, b.  rotating said means wherein said blade engages said ice floes in either a lifting or depressing mode thereby causing said floe to fail in flexure.

Abstract: ABSTRACT     An analogue display with a panel having an electro-optic medium contained between two sets of electrodes.  One set is arranged in a plurality of segments each divided into inner and outer portions.  Each portion is planar and has a plurality of digits.  The digits of one portion are inter-posed alternate with, and in between, the digits of the other.  The other set has a planar meander configuration modified by an electrode interposed in its folds.  The sets of electrodes when registered one over the other define two subsets of different selectable index positions.  Selected alternating voltages are applied simultaneously to the electrodes maintaining the panel ON at two selected index positions and OFF elsewhere to display each one of two different indices.  Preferably the voltages are selected from the set (+2V, +V, -V) of RMS magnitudes (2Vc, Vc, V ) where V  is equal to the thres-hold voltage of the panel.  The panel may contain liquid crystal material, as medium, to perform as a dyed phase change, or twisted nematic effect device.

Abstract: ABSTRACT A turret mounted series of photocomposing disc fonts wherein the turret has a series of disc hubs all having a different elevation in order that the disc members may be bunched together in overlapped relationship and hence occupy a minimum area within the photocomposing machine.  The turret is rotated to select a particular disc for insertion into an optical system, and is advanced or retracted along its own axis according to the elevation of the particular hub selected in order that the optical system of a photocomposing machine may remain stationary, and the particular disc member be brought to the proper focus position within the optical system.  The advance in the art is primarily in the placement of the discs in overlap relationship and then advancing or retracting the turret in order to accomplish proper positioning of the disc as opposed to the concept of the prior art in keeping all discs on one plane and then rotating the turret to bring each disc in turn into the optical system.

Abstract: ABSTRACT OF THE DISCLOSURE         An ignition system for internal combustion engine, which controls the ignition coil primary current according to the magnitude of the floating capacitance in the secondary side wiring section of the ignition coil, by determining the floating capacitance from the negative slope of rising of the secondary voltage produced in the ignition coil in response to the cutoff of the primary current and the primary cutoff current value, the slope being determined by measuring the period T until the secondary voltage reaches a predetermined voltage value.  When the floating capacitance is increased, the primary cutoff current value is increased to increase the coil energy so as to increase the secondary voltage generated in the ignition coil for preventing the generation of a miss-spark.

Abstract: ABSTRACT OF THE DISCLOSURE          Timing errors in a color television signal equal to a fraction of the nominal period of one cycle of color burst are corrected by clocking an analog-to-digital converter during each horizontal line interval of the television signal with two clock signals having the same nominal frequency equal to a multiple of that of the color burst.  During the color burst interval of each horizontal line, the analog-to-digital converter is clocked by a stable time base reference clock signal and the obtained digitized color burst is stored in a recyclable digital memory.  Following the color burst interval, the stored digitized color burst is regenerated for the remainder of the horizontal line and a clock signal derived for use in clocking the analog-to-digital converter.  The digitized television signal provided by the analog-to-digital converter is written into a clock isolator at times determined by the clock signal derived from the digitized color burst and, thereafter, read from the clock isolator at times determined by the reference clock signal.  Timing errors exceeding the nominal period of one color burst cycle are corrected by writing the digitized television signal from the clock isolator into a following random access memory and incrementally adjusting the memory's read time in accordance with such errors measured in steps equal to the period of one color burst cycle.          The stable time base reference clock signal is coupled to control the signal processing following passage through the clock isolator.

Abstract: IMPROVED CHEMICAL CUTTING APPARATUS Abstract An improved chemical cutting apparatus for cutting objects in well bores such as, for example, tubing in the bore of an oil or gas well.  The apparatus is properly positioned relative to the object to be cut by means of a casing collar locator, and an igniter is fired which in turn activates a gas generator.  Pressure from the gas generator axially displaces a slidable piston having suitable anchor means connected thereto.          Movement of the piston causes the anchor means to move into contact with the object to be cut, thereby anchoring the apparatus relative to such object.  Pressure generated in the gas generator is communicated through a passageway in the slidable piston and forces a chemical cutting agent into a chamber containing a reactant.  The reaction of the chemical cutting agent and reactant increases the pressure and temperature within the chamber thereby displacing along the axis a second slidable piston.  Movement of the second slidable piston exposes radial exhaust orifices thereby allowing the reacting elements in the chamber to escape with great velocity and to contact the object to be cut in incendiary fashion.  The improvement according to the present invention resides in the provision of pressure relief means intermediate the gas generator and the chemical cutting agent for diverting a portion of the gas away from the chemical cutting agent so as to reduce the likelihood of release of the chemical cutting agent in the event the apparatus is mishandled or malfunctions.
