Filed:

Mar 12, 2003

Appl. No.:

10/385429

Inventors:

James Isaac Meyer - Spearfish SD, US

Assignee:

RAMVAC Dental Products, Inc. - Spearfish SD

International Classification:

G01L007/04

US Classification:

73732, 73 116, 73 132

Abstract:

A vacuum flow measurement device measures the quantity of air flowing into a high-volume evacuator (HVE) vacuum tip commonly found in dental treatment rooms. The device includes a tubular member constructed to mimic internal structural characteristics of a HVE tip. The tubular member includes a valve end coupleable with a HVE valve and an open end. A pressure gauge is connected to the tubular member via a port spaced from the open end of the tubular member. When the vacuum flow measurement device is coupled with the HVE valve, an air flow rate is determined as a function of pressure measured via the pressure gauge.

International Classification:

G06F 19/00

US Classification:

702182, 73 185

Abstract:

A vacuum-strength measurement device is utilized to determine vacuum producer system performance specifications and system parameters. A flow ability factor can be determined that represents the effect of system piping and usage area equipment on performance. With the flow ability factor, a vacuum strength requirement can be determined to effect a target vacuum performance. For system design, design parameters can be established based on a relationship between a desired flow ability factor and an amount of vacuum strength required to match target vacuum performance.

International Classification:

A61C 17/00

US Classification:

95 24, 96168, 433 95

Abstract:

A separating tank assembly enables a dental vacuum separating tank to be drained without using a pump and without turning off or isolating the vacuum source from the tank. A drain tank is provided in fluid communication with the separating tank, and a control valve controls a pressure differential between the drain tank and the fluid tank. When the separating tank is filling, the drain tank and separating tank pressures are equalized, and the tanks are in fluid communication. When the fluid in the drain tank reaches a predetermined level, the solenoid opens the drain tank to atmosphere, blocking fluid communication between the separating tank and the drain tank and opening fluid communication between the drain tank and a sewer drain. After the fluid is drained, the solenoid reopens fluid communication between the separating tank and the drain tank, and the pressures in the respective tanks are equalized.

Abstract:

The present application relates to an input torque measuring device for a drive train of a bicycle. The drive train includes a first crank arm and a second crank arm. An inboard end of each crank arm is rotatably mounted to the bicycle at a bottom bracket of the bicycle. At least one chain ring is configured to rotate a driven wheel of the bicycle. A spider is connected to the first crank arm adjacent the bottom bracket and extends out to the at least one chain ring. The chain ring is attached to the spider by a fastener extending through a bushing within an opening of the spider. Sensors may be attached to the spider or the crank arms and may be directly connected to a flexible circuit board. The sensors, the flexible circuit boards and other components of the input torque measuring device may be encapsulated in a protective material.

A spider is connected to the first crank arm adjacent the bottom bracket and extends out to the at least one chain ring. The spider is configured to transmit force applied to the crank arms directly to the at least one chain ring. The spider may include a plurality of sensors configured to respond to the force applied by the spider to the at least one chain ring. The sensors produce an electronic signal relative to the force transmitted by the spider to the at least one chain ring and a processor configured to receive the electronic signals from each sensor of the spider.

US Classification:

210/787000, 210/804000, 210/532100, 210/512100

Abstract:

A particle separator includes a vortex chamber receiving feed slurry via a feed inlet. The feed inlet is positioned relative to the vortex chamber to effect rotation of the feed slurry upon entry in the vortex chamber and to generate a fluid vortex. The vortex chamber includes a conical section beneath the feed inlet, wherein the conical section terminates at an apex. A bulb housing is coupled with the vortex chamber and includes a vortex destroyer disposed adjacent the conical section apex. The vortex destroyer serves to contain the fluid vortex to the vortex chamber. A settling chamber is defined by the bulb housing beneath the vortex destroyer for collecting solid particles.
