A method, system and apparatus for wrapping objects for liveness in a collaborative environment. In a preferred aspect of the present invention, a method for enabling liveness for a non-live object can include the step of wrapping the non-live object to emulate liveness in a collaborative environment. Preferably, the wrapping step can include selecting at least one attribute of the non-live object, repeatedly updating a status of the at least one attribute for the non-live object, and, providing the repeatedly updated status to the collaborative environment in order to emulate liveness for the non-live object.

A system for providing a user status message in an instant messaging system that permits editing of the user status message by the owner of the status message and other users, and that displays information in the status message regarding the editing history of the status message. An edit history for each status message is provided, including a date and time stamp associated with each of a number of entries within the status message. Each entry in the status message is further provided with an indication of the user that authored the entry. The owner of the status message and users other than the owner of the status message are permitted to add entries to the status message through interfaces provided by the disclosed system. The system may further provide the ability to include links to additional information within the status message entries based on detection of strings of adjacent characters having a predetermined capitalization format.

The present invention provides a user interface that includes a first column for chronologically displaying a set of messages (objects) in a conversation, and a second column for displaying a branch of messages (objects) corresponding to a message (object) selected in the first column. The user interface further includes, among other things, a list of participants to the conversation, a vertical index (time line), a list of related conversations and a conversation map that illustrates a hierarchy of the conversation. Each message (object) in the first column can have an associated indicator for indicating a quantity of predecessors and successors to the set of messages (objects), as well as an in-line reply button for replying to the set of messages. Each of the messages displayed of the second column can have one or more associated navigation buttons for navigating adjacent hierarchical levels.

The invention is directed to a start-assist device on a membrane carburetor of an internal combustion engine in a motor-driven chain saw which is to be started manually. The carburetor includes a control chamber delimited by a control membrane. The control chamber is supplied with fuel from a fuel tank via control valve. The control valve is opened by the control membrane when the underpressure builds up in the control chamber so that fuel flows in. This fuel is supplied to the air-inducting intake channel via an idle nozzle and a main nozzle. The fuel feed system further has an outlet for vapor bubbles or the like. A pump which is driven indirectly from the start operation is provided and has a suction connection connected to the outlet in order to ensure, with few start attempts, a reliable start of the engine independently of the temperature state of the engine and other influences.

The invention is directed to a two-stroke internal combustion engine for handheld portable tools such as a motor-driven chain saw with the engine having a piston guided in a cylinder. The base of the piston is rotationally symmetrical and delimits a combustion chamber. An injection valve is mounted in the cylinder wall opposite an exhaust opening for exhaust gases. The injection valve injects fuel toward the piston base at an angle of less than 90.degree.. At least one overflow opening is arranged in the cylinder wall between the exhaust opening and the injection valve. Combustion air flows in through the overflow opening with the downward movement of the piston. The injection jet is directed opposite to the flow direction of the entering combustion air. The injection jet is directed for the most part to the half of the piston base which is disposed away from the exhaust opening and the injection opening is the last opening to be closed by the piston travelling toward top dead center. The duration of injection is continued beyond the closure of the overflow opening and of the exhaust outlet. In this way, an optimal air/fuel mixture is assured even at high rotational speeds.

A pneumatically operated fuel injection pump has a work chamber which is partitioned by a membrane into a pulse chamber and a return chamber. The pulse chamber is charged with crankcase pressure from a two-stroke engine while a counterforce is built up in the return chamber which varies with rotational speed. A counterforce is developed by means of a precise pressure control in the return chamber which makes possible a highly precise injection adapted to rotational speed. For this purpose, the return chamber is connected with an adjusting volume via a throttled flow path. In addition, a leaf spring is mounted in the return chamber and is utilized as a return spring for the membrane.

An internal combustion engine has a cylinder (2) wherein a combustion chamber (3) is formed which is delimited by a piston (5) journalled to move back and forth. At least one transfer channel (14) is provided which connects the crankcase (4) of the engine to the combustion chamber (3) in at least one position of the piston (5). The engine has a supply channel (13) which opens with a supply channel inlet (11) at the cylinder bore (34). The supply channel (13) is connected to the transfer channel (14) via at least one piston pocket (22, 42) in at least one position of the piston (5). In order to achieve low exhaust-gas values of the engine, the piston pocket (22, 42) has a distance (a) to a lower edge (27) of the transfer window (15) which is less than the distance (b) to a lower edge (26) of the inlet (11) of the supply channel at bottom dead center of the piston (5). A method for operating an engine provides that the piston pocket (22, 42) is first connected to the transfer window (15) and then to the supply channel inlet (11) during the upward stroke of the piston (5).
