A marine propulsion system is configured to be assembled, as one unitary structure, into a marine vessel. A transom attachment member is provided and is attachable to both an engine and a drive unit to form a single marine propulsion system structure which can be lowered into an opening formed in a transom of a marine vessel.

A method for controlling the movement of a marine vessel comprises steps that rotate two marine propulsion devices about their respective axes in order to increase the hydrodynamic resistance of the marine propulsion devices as they move through the water with the marine vessel. This increased resistance exerts a braking thrust on the marine vessel. Various techniques and procedures can be used to determine the absolute magnitudes of the angular magnitudes by which the marine propulsion devices are rotated.

A torque transmitting device for use in conjunction with a marine propulsion system provides an adapter that is attached in torque transmitting relation with a propulsor shaft for rotation about a central axis of rotation. The first insert portion is attached in torque transmitting relation with the adapter and a second insert portion is attached in torque transmitting relation with a hub of the propulsor hub which can be a marine propeller or an impeller. A third insert portion is connected between the first and second insert portions and is resilient in order to allow the first and second insert portions to rotate relative to each other about the central axis of rotation. The adapter is shaped to prevent compression of the first, second, and third insert portions in a direction parallel to the central axis of rotation. The relative shapes of the various components and the resilience of the third insert portion, which can be a plurality of titanium rods, provides significant compliance of the device under low torque magnitudes, but at higher torque magnitudes it provides a significantly decreased compliance to facilitate torque transfer between a propulsor shaft and the propulsor hub.

A four cycle four cylinder in-line internal combustion engine is provided with a housing structure that contains two shafts which rotate in opposite directions to each other and at the same rotational velocity. Pairs of counterweights are attached to the two shafts in order to provide a counterbalance force which is generally equal to an opposite from the secondary shaking force which results from the reciprocal movement of the pistons of the engine. The first and second shafts are rotors of a supercharging device, such as a Roots blower. The rotational speed of the first and second shafts is twice that of the rotational speed of the crankshaft of the engine and the provision of counterweights on the first and second shafts balances the secondary forces caused by the reciprocal motion of the piston in the engine.
摘要:
A combination of versatile and inexpensive elements are combined on site to create an impermeable assembly which collects water falling through a grating or cracks between adjacent boards of a deck and completely drains it to one or more points at a selected edge. The impermeable assembly is comprised of a plurality of peaks and valleys configured to simplify installation, conserve headroom and provide an aesthetically pleasing finished surface. In a first embodiment, a collector collects the water falling through cracks between boards spanning the space between adjacent joists from which it drains transversely to a gutter positioned beneath the joists. The gutter drains the water longitudinally to the perimeter of the deck.

An apparatus is provided for controlling discharge of oxygen from an oxygen supply source to a patient. The apparatus includes an oxygen supply inlet, a pressure regulator coupled to the oxygen supply inlet and configured to reduce pressure of oxygen received from the oxygen supply inlet to a selected magnitude, a flow controller coupled to the pressure regulator and configured to meter oxygen received from the pressure regulator at a selected flow rate, and an oxygen distribution assembly including a pneumatic demand oxygen valve and a conduit conducting oxygen discharged from the flow controller through the pressure regulator to the pneumatic demand oxygen valve for delivery to a patient. The flow controller includes a chamber and a rotary valve for splitting oxygen discharged from the chamber into a first stream in an oxygen supply passageway for use by a patient and a second stream in a diaphragm supply passageway for controlling operation of pneumatic demand oxygen valve.
摘要:
A hanging device for suspending one or more implements which have either elongated generally straight handles or body portions. The device includes one or a plurality of rings or annular members each having a central open area. Each ring is attached to one end of a length of flexible cord, string, cable and the like at a peripheral point of each ring. Each ring, when the other end of each cord is attached to an overhead support, will hang downwardly edgewise when not in use. An implement may be suspended for above ground or floor surface storage in a generally upright, freely swingable fashion by first passing the handle or body portion into the central open area of one ring, the central open area being somewhat larger than a diameter or thickness of the handle or body portion. By then allowing the handle or body portion to simply move by gravity into a generally upright orientation, the ring automatically moves into a canted position with respect to the handle or body portion and frictionally or penetratingly engages to hold and suspend the implement.

A telecommunication system provides voice and data communications over a conventional telephone line between a server station and a client station using visual forms. The client station includes a processor, display, telephone, and data circuit-terminating equipment (DCE) for data communications. The server station includes a processor, DCE, and either a telephone or a voice card for audio communications. Each DCE includes a modem, a start signal generator for transmitting a start signal over the telephone line prior to transmission of data by the modem, a start signal detector, and a switch that automatically switches the DCE from voice mode to data mode while data is being communicated. The client processor also includes a definition of a visual form having a number of controls with predetermined properties, including properties defining permissible actions that can be taken with respect to each control and instructions to be executed in response to specified actions. The client employs a mouse, keyboard, or the like to select a control in the visual form and to perform an action on the selected control. At least some of the controls include a property directing the client processor to switch the DCE to data mode, transmit data identifying the action, and then return to voice mode. The server processor is programmed to execute steps in response to the actions received from said client station. The visual forms at both stations can be linked so that they are automatically updated to reflect actions at the other station.
