Title: Method for reducing the kerf width made by a circular saw blade
Inventor: MARTIN RICHARD R
IPC: B23D47/00
Filed: 1994-02-14
Abstract: A guiding system for large circular saws wherein the guiding pads are positioned according to a typical angular wavelength of a circumferential vibration wave of the saw blade when rotating at an operating speed. In one embodiment, the frequency of a natural circumferential vibration wave is measured before positioning the guiding pads. Two sets of guiding pads are spaced apart a distance equal to about half the angular wavelength of such natural vibration wave. This distance corresponds to an angular distance between two successive opposite peaks or crests of a sinusoidal wave in the saw blade. The consequence of two successive opposite peaks entering the guiding pads at the same time has the effect of dampening the vibration very quickly, by acting upon both sides of the saw blade simultaneously, to reduce the amplitude of the wave, while maintaining balanced axial impact on the saw. The guiding pads are further positioned in a true co-planar relationship with the saw blade by means of two superimposed three-point levellers, on the pad supporting members.

IPC: H01L23/50
Filed: 1993-02-18
Abstract: ABSTRACT OF THE DISCLOSURE      A method and resulting structure for constructing an IC package utilizing thin film technology.  The package has a bottom conductive plate that has a layer of ceramic vapor deposited onto the plate in a predetermined pattern.  Adjacent to the insulative layer of ceramic is a layer of conductive metal vapor deposited onto the ceramic.  The layer of metal can be laid down onto the ceramic in a predetermined pattern to create a power plane, a plurality of signal lines, or a combination of power planes and signal lines.  On top of the layer of conductive material is a lead frame separated by a layer of insulative polyimide material.  The polyimide material has a plurality of holes filled with a conductive material, which electrically couple the layer of conductive material with the leads of the lead frame.  The power and ground pads of the integrated circuit are connected to the layer of vapor deposited conductive material and conductive plate, which are also coupled to the corresponding leads of the lead frame, thereby connecting the IC to the leads of the lead frame.  The signal pads of the IC are connected to the lead frame and/or signal lines formed within the layer of vapor deposited conductive material.  The IC and attached circuit package can then be encapsulated in a plastic shell.

Patent CA-2131678-A1 (CA)
Inventor: ZITTEL DAVID R
IPC: B01D33/11
Filed: 1994-09-08
Abstract: An interior wedge wire drum screen is mounted wholly within an exterior drum screen of narrower wedge wire spacing, and both are mounted to a frame and caused to rotate about a common central axis. One and of the outer drum is open and the other is closed by a disc-shaped drum head. The inner drum has an open end which is spaced inward of the open end of the outer drum. The waste water is presented to the surface of the inner drum screen by a waste water infeed which employs a vertical column.  The column extends upwardly of an inlet and has a gradually increasing cross-section for reducing the flaw of velocity of the waste water. A horizontal trough extends along the axis defined by the drums and communicates between the top of the column and a tray. The edges of the tray terminate in weirs which are parallel to the sides of the inner drum. Water flows in a smooth sheet over a weir to impact the sides of the inner screen with low velocity. As the drums rotate the accumulating filtrate is moved by a spiral auger which progresses the filtered material to the open ends of the drums. The material from the inner drum falls to the surface of the outer drum, and is progressed to a waste collection trough.

Title: Internal combustion engine low temperature starting system
Inventor: GRAY CLINT D
IPC: F02N19/04
Filed: 1995-03-24
Abstract: A compression ignited, spark ignited, or surface ignited engine single or multi-cylinder low temperature starting system is positioned permanently or temporarily in the intake system during the engine starting and warming-up period for an extremely cold temperature engine condition.      The low temperature starting system for these engine types is capable of starting on a wide variety of liquid fuels, E.G., high or low fuel volatility, high or low fuel boiling range and gaseous fuels. A pre-heat device which is fuel fired, electrically heated, chemically heated, heated by thermal storage or other means is used to pre-heat the air or air-fuel mixture. In any one of four different configurational modes, after an initial pre-heat period, air or an air-fuel mixture is drawn through a heat exchanger with an inlet restriction that acts to increase the air residency time in the heat exchanger which increases the temperature of the inducted air that in-turn reduces the opportunity for cold air to reach the combustion chamber and yields a rich air-fuel mixture in the combustion chamber. The heated rich air-fuel mixture in the combustion chamber is further heated by compression during the compression stroke to permit combustion to occur in a sustained manner prior to and after start-up. This invention allows engine startup at extremely low ambient temperatures. Cold cranking time and energy are substantially reduced due to the rapid build-up of heat in the combustion chamber.

Inventor: AMKRAUT ALFRED A
IPC: A61K47/48
Filed: 1994-02-22
Abstract: Compositions and methods for the oral administration of drugs and other active agents are provided. The compositions comprise an active agent carrier particle attached to a binding moiety which binds specifically to a target molecule present on the surface of a mammalian enterocyte. The binding moiety binds to the target molecule with a binding affinity or avidity sufficient to initiate endocytosis or phagocytosis of particulate active agent carrier so that the carrier will be absorbed by the enterocyte. The active agent will then be released from the carrier to the host's systemic circulation. In this way, degradation of degradation-sensitive drugs, such as polypeptides, in the intestines can be avoided while absorption of proteins and polypeptides from the intestinal tract is increased.
