Abstract: ABSTRACT OF THE DISCLOSURE          An improved two-way torque limiting coupling (10) of the type utilizing a helical coil clutch (18) is provided.  The coupling provides a driving connection between a first (12) and a second (14) rotatable adjacent members.  The first member includes a bore (24) opening to an end (20) in which one end of coil clutch is received in interference fit to define an internal clutch interface (34) and the other member defines an annular outer periphery (26) about which the other end of the coil clutch is received in an interference fit to define an external clutch interface (36).  For the direction of rotation tending to expand the coil clutch (18), the coupling will slip at the external interface (36) which is the low maximum torque transfer direction of rotation for that interface and for the direction of rotation tending to contract the coil clutch (18), the coupling will slip at the internal interface (34) which is the low maximum torque transfer direction of rotation for that interface.

Abstract: ABSTRACT OF THE DISCLOSURE         Printing apparatus of the dot matrix type is provided herein comprising a plurality of print wire actuators employing moving coils. The wire printing tip of each actuator is activated by the coil magnetic field interacting with an efficiently applied magnetic field substantially perpendicular to the direction of current flow in the coil.  The actuator comprises a thin planar lamination having low inertia and high heat dissipation for balanced pivotal motion to provide high speed letter quality printing and high resolution graphics.  One advantage is that the mass of the print wire actuator including the print wire is reduced.          Another advantage is that the moment of inertia of the actuator is minimized and the torque to inertia ratio is maximized.  A further advantage is that extensive bending of the print wires is eliminated while having a large number of print wires closely packed for producing high quality print.  Still another advantage is that high quality print is obtained from a dot matrix print head in a single pass relative to the paper web.

Abstract: ABSTRACT OF THE INVENTION    An improved computerized moment stability system is provided which will rapidly obtain the solution to operational and post damage stability problems which may be present on an oceangoing vessel.  The system includes three functional modules plus an initialization data base module.          The data base modules stores the basic stability data concerning all watertight compartments and tanks onboard the vessel.  An operational stability module is provided for performing the operational calculations to determine the stability parameters which exist under normal conditions. In addition, the operational module can provide reports concerning the day to day inventory of consumables as well as help in properly performing the loading and unloading of the vessel to maintain a safe, stable, condition at all times.  A stability assessment module is included which performs the necessary calculations for the determination of post-damage conditions and the stability parameters for the vessel after battle, collision or grounding damage has been sustained.  The post-damage stability is compared with the predamage stability in the corrective strategy module whereby either operator corrective strategy or system developed corrective strategy can be established for correcting the questionable stability of the vessel. Various corrective strategy analyses can be hypothetically attempted to determine the best strategy to follow.  The data base module can also provide a system backup through the production of a complete compartment and tank stability card file for possible post-damage stability analysis for the vessel under emergency conditions.

Abstract: Abstract of the Disclosure A washing machine includes a washing tub whose peripheral wall is formed of an upper peripheral wall section and a lower peripheral wall section located thereunder and adapted to be rotated in two opposite directions.  The washing tub receives laundry and water therein.  In the washing mode, the lower peripheral wall section is rotated both clockwise and counterclockwise.          Thus, the laundry is circulated by frictional contact with the lower peripheral wall section and is washed by the effect of multiplication of frictional forces produced by contact with the upper and lower peripheral wall sections.  A projection protrudes upward from the inner bottom surface of the washing tub and is located inside the lower peripheral wall section to touch the laundry to increase the cleaning efficiency.

Abstract: FRONT SUSPENSION SYSTEM FOR A MOTORCYCLE                 Abstract of the Disclosure A suspension system for the front wheel of a motorcycle.  A pair of upper and lower control arms extend forwardly from the body of the motorcycle and are attached by universally pivotable ball joints to a kingpin which extends along one side of the front wheel.  The front wheel includes an offset hub and is journalled in a cantilevered arrangement to a bearing assembly which is affixed to the lower end of the kingpin and which is positioned at the center of the wheel.  The control arms are hinged to the body and are appropriately sprung and damped so that the kingpin and front wheel swing vertically in suspension travel with respect to the body in response to weight and shock loads on the front wheel.  The kingpin is connected to a handlebar assembly by means of a telescopic splined steering column.  A variety of springing and damping mechanisms may be adapted to the suspension system.  The system minimizes the tendency of the motorcycle to drive during hard braking of the front wheel, and also results in weight and shock loads being transmitted directly to points on the body which are low and close to the center of gravity of the motorcycle.

For the transmission of each packet, an abort signal of the protocol is initially transmitted, and the packet is transmitted when the DMA channel is free after a delay equal to the packet transmission turnaround time.  In response to receipt of the abort signal, the DMA channel is reserved for reception of a packet within a time-out period.  The DMA channel adopts a receive state in response to the abort signal either immediately if it is free, or at the end of transmission if a packet is currently being transmitted.               - i -
