Title: Apparatus for the preparation and execution of tests on the sedimentation rate of organic liquids and other
Inventor: RICCI ANTONIO
IPC: B01L7/04
Filed: 1990-02-19
Granted: 2000-05-02
Abstract: The apparatus of the present invention can be used to measure sedimentation rate of samples. The samples are placed in a sample rotor and are rotatable about a sample rotor axis.      The sample rotor axis can be moved into two positions. In one position the sample rotor axis is substantially horizontal and in the other position the sample rotor axis is substantially vertical. Rotation of the sample rotor axis about the sample rotor axis causes stirring of the samples when the sample rotor axis is horizontal. When the sample rotor axis is substantially vertical settling of the samples occur. Step rotation of the sample rotor brings the samples to a reading means in order to analyze the samples. An optical signal sensor moves long the sides of the test tubes for measuring the sedimentation rate.

Title: Automatic sheet feed active alignment system
Inventor: EBERSOLE ANTHONY W
IPC: B41J13/26
Filed: 1990-04-17
Granted: 2001-08-14
Abstract: An automatic sheet feed alignment system is de-scribed for feeding sheets of print media such as paper to print mechanism in alignment with the print mechanism. A single motor drives a main sheet advance roller, and is also coupled to a sheet pick roller through a non-revers-ing clutch. An idler roller is disposed adjacent the drive roller. To feed a sheet into the print position, the motor drives the main drive roller and sheet pick roller in a sheet advancing direction, until the sheet leading edge is advanced into and past the nip between the main drive and idler rollers. The motor direction is then reversed so that the main roller retracts the sheet.      Because the sheet pick roller is not driven in the reverse direction, a buckle is formed in the sheet between the sheet pick roller and the nip, tending to align the leading sheet edge with the nip. The motor direction is then reversed to drive the sheet forward to the print position, its leading edge having been aligned.

Granted: 1995-08-29
Abstract: A self-drilling plastic anchor installable in a wall by means of a screwdriver, the anchor being adapted to receive a threaded fastener that serves to hold a fixture or other object against the wall.  The anchor includes an externally-threaded shank section having an enlarged head that is engageable by the screwdriver and a cavity to receive the fastener. Extending from the lower end of the shank section is a drill section that terminates in a point that lies on the longitudinal axis of the anchor.          When the anchor is applied to the wall, the point penetrates its surface, so that the anchor may then be turned by the screwdriver about the point.  The drill section is formed by a pair of cutting blades on opposite sides of the anchor axis and a pair of guide blades, each angled relative to a respective cutting blade.  When the anchor is turned in, the cutting blades guided by the guide blades proceed to bore a hole in the wall, and when the shank section enters the hole, its bank is tapped by the threading of the shank section until the head thereof engages the surface of the wall to complete the installation.  The fastener may then be screwed into the cavity of the shank section.  The undersurface of the head has ratchet teeth formed therein which when the head engages the wall surface, the teeth grip this surface to resist turning out of the anchor.

Abstract: A high pressure coupling for hose-like objects in which the nipple structure includes a main portion, a connecting nipple portion extending from the main portion in one direction and a nipple portion extending from the main portion in the opposite direction.  A sleeve-like member made from tubular stock is adapted to be securely connected to the nipple structure by crimping, flanging or the like.  The nipple portion includes outwardly projecting, rounded-off ribs cooperating with rounded-off grooves in the sleeve-like member so that the hose inserted between the nipple portion and the sleeve-like member is held securely in position after the nipple portion is internally expanded with subsequent reduction of the cylindrical surface of the sleeve-like member.  Both the nipple structure as well as the sleeve-like member are made from appropriate stock machined accurately to the required dimensions.  Sharp edges provided in the nipple main portion will anchor themselves securely in the crimped or flanged-over end of the sleeve-like member to assure a secure fastening between these two parts.  A ram-actuated machine for installing the coupling of this invention includes a frame structure which supports a die assembly as well as guide columns slidingly supporting a ram cap assembly.  A ram head assembly to which a mandrel carrying one or more expanding members is connected, is adapted to be reciprocated by the hydraulic ram mechanism with the parts so arranged and constructed that initially the expanding member or members will expand the nipple portion during downward movement of the ram head mandrel assembly.  The internal expansion of the nipple portion is completed when the ram head assembly comes to rest on the ram cap assembly, itself resting on the main nipple portion.  Further downward movement of the ram head assembly will cause the sleeve-like member to be forced through the reducing die by way of the ram cap assembly and the main nipple portion to which the sleeve-like member is securely connected.

IPC: B62D49/00
Filed: 1992-02-20
Granted: 1994-10-04
Abstract: A work vehicle configuration has the engine directly over the front axle, the cooling system radiator far enough forward to allow even large tires to turn into the volume defined between the radiator and the engine, and a tall but very narrow transmission forward of the operator enclosure.  This allows the vehicle to be provided with a wasp-waist, significantly improving visibility. This also allows a recessed area in the vehicle body adjacent to the front tires, allowing a sharper turning radius and improved maneuverability.  This placement of the transmission frees space under the operator enclosure, allowing use of a significantly larger fuel tank.  Finally, the placement of the main vehicle components away from the front tires and out from under the operator enclosure allows improved access and serviceability for the tractor.
