Title: Improved transfer pump
Inventor: HANSEN MILTON NOERSGAARD
IPC: F04C15/00
Filed: 1992-03-20
Granted: 2002-06-04
Abstract: An improved rotary, gear within a gear transfer pump, including a pump housing having a circular pumping chamber communicating with a first port and a second port. An externally driven rotor is rotatable within the chamber and is located in meshing relationship with an internal idler gear such that upon rotation of the rotor, fluid at the first port is drawn into the pumping chamber and transferred under pressure to the other port. An annular bearing mounted within the housing in confronting relationship with a peripheral surface of the rotor, provides a bearing surface and supports radially directed loads exerted by unbalanced fluid forces on the rotor. A pressure balancing circuit is provided for transferring pressurized fluid from a discharge region in the pump to a backside of the rotor to at least partially balance axial forces exerted on the rotor by pressurized fluid at or near the discharge region. To provide bi-rotational capability, a cross-communicating passage and check valves are used for controlling the flow of fluid into the pressure balancing circuit. A vented seal chamber is also provided which includes passages and check valves communicating with the first and second ports which are arranged such that when the seal chamber exceeds inlet pressure, the check valve associated with the port acting as an inlet opens to discharge fluid from the seal chamber. A replaceable foot bracket is provided so that the mounting height of the pump can be selected to coincide with a mounting height of a drive motor to which it is connected eliminating the need for shims or other adjustments. An alternate rotor is disclosed including trimmed regions for reducing viscous friction when pumping high viscus fluids.

Title: Tamping shoe of a vibration rammer
Inventor: YAMAGUCHI HITOSHI
IPC: E02D3/02
Filed: 1992-06-16
Granted: 1998-06-09
Abstract: A tamping shoe for a vibration rammer has a plurality of through holes communicating between an under surface and an upper surface. The through holes permit the escape of air trapped between the under surface and a surface being tamped, and thereby reduce the amount and pressure of air compressed under the tamping shoe. This reduces noise pollution produced during tamping. In a preferred embodiment, the through holes are tapered outward in the direction of air flow. Air passing through a through hole in a mount is released through a further through hole bored through a wall of the mount.

Granted: 2001-01-02
Abstract: Complex metal structures are formed in microminiature dimensions utilizing multiple mask exposures which are capable of producing substantially arbitrary three-dimensional shapes. A first layer of a primary metal is electroplated onto an exposed plating base to fill a void in a photoresist, the photoresist is removed, and a secondary metal, which can constitute a sacrificial metal, is electroplated over the first layer and the plating base.      The exposed surface of the deposited secondary metal is then machined down to a height which exposes the first metal to produce a substantially flat, uniform surface extending across both the primary and secondary metals.      The secondary metal facilitates machining of the primary and secondary metals because of these mechanical stability provided by the secondary metal to the primary metal.      After the first layers of the primary and secondary metals have been machined, another photoresist layer can be applied over the primary and secondary metals, and a second layer of primary metal is electroplated. A further layer of secondary metal can be also electroplated if desired.      The process of machining and electroplating can be repeated until the desired structure is formed. Secondary metal is removed by an etchant which does not etch the primary metal.
