Title: Fuel injection control method for IC engine - controlling fuel w.r.t. oxygen content in exhaust gases with correction for dynamic changes in oxygen content
Inventor: ENGEL GERHARD DIPL ING
IPC: F02D41/14
Filed: 1991-04-12
Abstract: The exhaust system has a sensor for oxygen content and the signals are processed to derive a lambda value as well as a differential of the lambda value, defining the dynamic state of the value.

The dynamic rate is limitted by a fixed level, which operates above set dynamic rates. For low rates a preset ramp rate monitors the lambda level. The system operates for a diesel engine as well as an ignition fired engine. ADVANTAGE - Less carbon emission, follows dynamic changes in engine operation.

Title: Spinning frame - has pneumatic cop or tube grips with automatic air shut off when removed
Inventor: LANGER ROLF DIPL ING
IPC: D01H9/00
Filed: 1991-08-26
Abstract: Spinning cops and tubes may be held stationary by an appliance attached to the spinning frame. This is operated pneumatically by an air pressure supply to separate inflatable grippers, which can be withdrawn from the socket. The air supply is automatically shut off at the socket outlet, until the gripper is replaced. The socket (3) is pref. screwed (4) to a rail (5) along the spinning frame. An air pressure supply tube (6) is attached to the rail, and in each working position a socket is fixed, from which there is a connection (7). This feeds the gripper (1) to inflate the flexible tube (2) until it meets the resistance of a tube or cop. If the gripper is removed, the spring (9) pushes the valve (8), so that the air inlet (7) is closed. When the gripper is pushed back into the socket, the valve goes back against the spring to open the air tube (7). Other types of valve which can be released in the same manner are also proposed. ADVANTAGE - The appliances work immediately on account of the unrestricted air supply, without diminishing the operation of intermediate equipment.
