Abstract: MULTIPLE CAPACITOR MEANS IGNITION SYSTEM                   Abstract of the Disclosure A four cylinder, two-cycle internal combustion engine for an outboard motor includes a pair of energy storage power capacitors.  An engine driven alternator produces a generally sine wave output voltage having one-half cycle connected to charge one capacitor and the opposite half-cycle connected to charge the second capacitor by a suitable diode steering network. The output voltage frequency is greater than the firing frequency and a plurality of voltage cycles provide for charging of the capacitors to the desired level. A separate trigger capacitor is provided.  The trigger capacitor is coupled to be charged from the main alterna-tor through a low impedance network and additionally from the main capacitor charging circuit through a high im-pedance network which may also function as a safety cir-cuit means.  Each capacitor is recharged by a plurality of half-cycles and during such period of engine revolu-tion the alternate capacitor is being finally charged and discharged.  The safety circuit means provide for relatively minute or slow discharging of the capacitor means between cycles and thereby essentially fully dis-charge the capacitor means when the system is turned off and thus prevent maintaining of dangerously high voltages in the system at turn-off.

Abstract: ABSTRACT     This invention proposes a partial pressure jerkin that includes a front panel and a rear panel to overlie the anterior and posterior region of the trunk respectively of a wearer.  The front and rear panels are joined at selected areas of their periphery to provide head, arm and leg apertures.  An opening is formed in the rear panel extending from the head aperture to one of the leg apertures to permit access to the garment and a zip fastener is provided to close the opening.  A single bladder is attached to the inside of the outer garment and is positioned between the front panel and the chest of the wearer.   The bladder extends between the head and arm apertures to terminate in a region adjacent to the shoulder blades of the wearer and covers the anterior portion of the trunk all the way down to the upper thighs and inguinal areas.  The bladder is formed from two skins bound together along their peripheral edges and having a dissimilar elastic modulus so that the stretchier inner skin will conform to the countours of the wearer torso and the stiffer outer skin will react to prevent outward ballooning and to direct the compressive forces towards the torso of the wearer upon inflation of the bladder.

Abstract: Abstract of the Disclosure A data transmission system is described where data signals are bidirectionally transmitted between a data transmitter and a plurality of data receivers in a self-clocking bit streams carried on true data and complement data signal lines and a non-return-to-zero (NRZ) bit streams on a return data signal line.  According to an inventive data transmission scheme, data signals are transmitted by the data transmitter by utilizing the four possible two-bit binary states of the true data and complement data signal lines.  Of the four two-bit binary states, a word state is provided before and after the data signal and a one state or zero state followed by a bit state is provided for each bit of the data signal. The data receivers detect the bit state to recover a bit clock signal and detect the one state and zero state to recover an NRZ data signal.  In response to the bit clock signal, the NRZ data signal is serially shifted into a register while a previously parallel loaded return data signal is shifted out of the register and applied to the return data signal line.  The inventive data transmission scheme is self-clocking and highly immune to speed and timing variations in the transmission.  The inventive data transmission may be advantageously utilized for data transmission in many different data transmission systems, such as computer systems for data transmission between a microprocessor and peripheral units and control systems for data transmission between a central control station and geographically remote stations.

Abstract: Ripper With Offset Impacting Means and Slotted Shank Abstract Previously known ripper apparatus comprise an impacting mechanism for applying impact forces to a ripper tip in an in-line relationship.  The high spring rate exhibited by the shank induces high peak internal impact forces, dissipates useful energy, and provides relatively shallow cutting depths.  In one aspect, the ripper apparatus of this invention overcomes the above problems by providing an offset relationship between a first line of impacting movement of a ripper tip and a second line whereat impacting forces are applied to a shank carrying the ripper tip and by further providing a spring mechanism for ensuring that the impacting forces are transmitted from the second line to the first line directly.  In another aspect, the spring mechanism induces an efficient transfer of impact energy from an impacting mechanism to the material being worked by the ripper tip, whether the first and second lines are offset or co-incident.

Abstract: Case 5664 HIGH PRESSURE FLAT BED FILTER                 ABSTRACT OF THE DISCLOSURE    In a filter device a filter media belt is positioned over a horizontal grid panel.  Ends of the belt extend beyond the panel and each is attached to a rotatable forward and rear spool carried outside a cover which encases the grid panel.  The cover defines an inner chamber above the grid panel which may be selectively sealed by a closure of doors located at each end of the cover.  The cover, doors, and grid panel are sufficiently reinforced to allow the inner chamber to be partially filled with a batch of a liquid-particulate mixture and then pressurized to force the liquid portion through the filter belt and grid panel.          During pressurization, longitudinal gasket devices maintain edges of the filter belt sealed against the grid panel.          With the liquid portion removed, the particulate in the form of a cake remains on the filter belt.  The chamber then is depressurized, the doors opened, and the belt moved forward by rotation of the forward spool.  During this belt movement, the particulate is removed from the belt and the belt cleaned.  The belt is then moved in a rearward direction to return the belt to its original position wherein the filter device is ready to process a further liquid-particulate mixture batch.
