Inventor: SIVIK MATTHEW R
IPC: C10L1/32
Filed: 1996-11-05
Abstract: This invention relates to compositions which are useful as additives in lubricants and fuels, and more particularly, to additives which are chlorine-free or contain only minor amounts of chlorine. More particularly, carboxylic compositions are described which are prepared by reacting a terpolymer derived from a mixture of monomers comprising ethylene, an alpha-olefin containing 3 to about 20 carbon atoms, and a non-conjugated polyene with an alpha,beta-monounsaturated dicarboxylic acid or reactive derivative thereof. These carboxylic compositions may be used in lubricating oil or fuel compositions or may be used to form carboxylic derivative compositions which are useful in lubricating oil and fuel compositions. Such useful carboxylic derivative compositions can be prepared by reacting at least one of the above-described carboxylic compositions with a reactant selected from the group consisting of (A) amines characterized by the presence within their structure of at least one H-N< group, (B) alcohols, (C) reactive metal or reactive metal compounds, and (D) a combination of two or more of any one of (A) through (C), the components of (D) being reacted with one or more of the carboxylic compositions simultaneously or sequentially in any order. In another embodiment, the carboxylic composition may be prepared by reacting a mixture of an alpha-olefin polymer, the above-described terpolymer, and an alpha,beta-monounsaturated dicarboxylic acid or reactive derivative thereof.

Abstract: An optical beam (8) in a scanning device is focused on an information layer (3) of a multi-layer optical record carrier. A focus control circuit (22) keeps the focal point (9) of the beam on the information layer. When the focal point jumps to another information layer, the focus control circuit does not monitor the so-called central aperture signal in order not to depend on the presence of information in the information layers. During the jump the characteristics of the feedback loop of the focus control unit are modified to avoid instabilities in the movement of the focal point during the jump. The characteristics of the feedback loop are restored after a predetermined period of time, then the focal is near the designated layer and the restored control loop focuses the focal point of the designated layer.

Abstract: A color sorting machine sorts particles of
different colors from raw material such as cereal grains
or the like. The machine has a down chute descending
towards a front side of the machine for letting raw
material particles flow down linearly, a photoelectric
detection device which subjects the raw material
particles jumped out of the down chute to light and
discriminates different-color particles in accordance
with difference in reflected light, and a nozzle device
which injects air to and blows off the different-color
particles. The injection nozzle device is situated on
the rear side of the machine with respect to a coming-down
locus of raw material particles from the down chute
and close to the coming-down locus. The sorting machine
further comprises a dust collecting device which is
situated on the front side of the machine with respect
to the coming-down locus of the raw material. The dust
collecting device has a dust collection opening which is
substantially opposite to the injection nozzle device
with the coming-down locus interposed therebetween,
sucks in and discharges dust scattered from the raw
material. The color sorting machine is highly precise in
sorting different-color particles and facilitates
cleaning of the dust collecting device.

Abstract: A system and method for automatically converting a compiled program that accesses objects stored in main memory into a program that accesses and updates persistently stored objects. An initial computer program includes original instructions for accessing and updating objects in at least a first object dass. The original instructions access and update objects in a computer's main memory. The system automatically revises the initial computer program to generate a revised computer program by adding to the original instructions object loading instructions and object storing instructions. During execution of the revised computer program, the object loading instructions load a copy of one of the persistently stored objects into a corresponding object in the computer's main memory when the object is accessed for a first time. The object storing instructions copy objects in the computer's main memory that contain new or modified data into corresponding persistently stored objects upon the occurrence of predefined events, such as the completion of a transaction. The system further revises the initial computer program to generate the revised computer program by adding to the original instructions dirty object marking instructions that, during execution of the revised computer program, keep track of which objects in the computer's main memory contain new and/or updated data. The object storing instructions copy only those of the objects in the computer's main memory that contain new and/or updated data.

vertical wall and another position in which the two
housings are disposed one behind the other for supporting
upon a horizontal surface. Preferably, in the position
