US Patent:

40600068, Nov 29, 1977

Filed:

Sep 20, 1976

Appl. No.:

5/724794

Inventors:

Stephen Carl Abel - Longmont CO
Jeffrey Allen Carlson - Longmont CO

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

F16G 1302

US Classification:

74258

Abstract:

A substantially plastic ladder chain is made continuous by affixing the exposed metallic cable ends thereof to a master coupling link of stainless steel or like material. The exposed metallic cable ends of the plastic ladder chain comprising plural braided cable also of stainless steel or like material are fastened in such a way to separate master cross links, of the aforementioned master coupling link, by master link side lock pins of brass or like material so as to form substantially a molecular bond. The master cross links are then connected together in a conventional manner by master link retainer clamps and master link retainer clips, thus forming the continuous ladder chain.

International Classification:

B23K 3102

US Classification:

228121

Abstract:

A method of bonding two crystals together is disclosed. A bond enhancing material such as chromium (Cr) is vapor deposited on one crystal, and on this is vapor deposited a noble metal such as gold (Au). On the other crystal a low melting point metal such as tin (Sn) or indium (In) is vapor deposited. In the case of In this can either be directly on the crystal or on a layer of bond enhancing material; in the case of Sn this must be on a bond enhancing material. On top of the low melting point metal a layer of the same noble metal is deposited to prevent oxidation thereof. The noble metal layers are brought into contact with each other in vacuum or inert atmosphere and pressure applied thereto at a temperature of 100. degree. C to 150. degree. C in the case of In and 100. degree. C to 200. degree.

Abstract:

The subject matter of this specification can be embodied in, among other things, a method of igniting an air/fuel mixture in an internal combustion engine includes receiving an air/fuel mixture into a pre-combustion chamber, the pre-combustion chamber enclosing a portion of an igniter, igniting the air/fuel mixture in in the pre-combustion chamber with the igniter to produce a flame, directing the flame to eject the pre-combustion chamber through a collection of passages in a wall of the pre-combustion chamber, toward a peripheral wall of a main combustion chamber of the internal combustion engine, igniting, by the flame, air/fuel mixture in the main o combustion chamber adjacent the peripheral wall, and then igniting air/fuel mixture in the main combustion chamber in a central region of the main combustion chamber with a propagating flame front of the ignited air/fuel mixture or a portion of the directed flame adjacent the peripheral wall.

International Classification:

F02D 41/30
F02D 41/24
F02P 5/04

Abstract:

A method of controlling combustion in an internal combustion engine includes measuring parameters of combustion in a cylinder of the engine during a combustion phase of the cylinder, after igniting an air/fuel charge in the cylinder, and calculating the heat release of combustion in the cylinder based on the measured parameters. An auto-ignition event of the air/fuel charge is identified based on the calculated heat release, and, based at least in part on the identified auto-ignition event, at least one of ignition timing in the cylinder for the next combustion phase of the cylinder or an amount of exhaust gas supplied to the cylinder for the next combustion phase of the cylinder is controlled to cause an auto-ignition event of the air/fuel charge in the next combustion phase to shift toward a specified crank angle.

Abstract:

A method of detecting uncontrolled combustion in an internal combustion engine includes sampling in-cylinder pressure sensor configured to measure pressure in a cylinder of the engine and generate a pressure signal, calculating a combustion intensity metric based on the pressure signal, determining a parameter describing how close the engine is to an uncontrolled combustion condition based on the combustion intensity metric, and controlling a substitution rate of a first fuel and a second fuel based on one or more of the parameter and the combustion intensity metric.

Abstract:

A system for controlling an internal combustion engine has an in-cylinder pressure sensor, a crank angle sensor and a controller coupled to receive inputs from the pressure sensor and crank angle sensor. The controller is configured to convert the cylinder pressure input into a combustion metric indicative of the combustion occurring in the measured cylinder and control fuel input and timing into the engine based on the combustion metric. The controller samples the in-cylinder pressure sensor at a high frequency during critical combustion events and at a lower frequency during the non-critical cylinder conditions.
