US Patent:

6730002, May 4, 2004

Filed:

Sep 28, 2001

Appl. No.:

09/967870

Inventors:

Patrick Hald - Park City UT
Gerald Nelson - Colorado Springs CO

Assignee:

Icon IP, Inc. - Logan UT

International Classification:

A63B 7100

US Classification:

482 51, 482 54

Abstract:

An improved lift apparatus for use in an exercise device having a support base and a moveable element is disclosed. The moveable element can be selectively raised and lowered relative to the support base by the user during operation of the exercise device. The improved lift apparatus includes: (i) a first lift motor; (ii) a second lift motor; and (iii) a synchronization mechanism for synchronizing the first and second lift motors. A belt safety mechanism for controlling unanticipated movement of the endless belt is also disclosed.

International Classification:

A63B 22/02

US Classification:

482 54, 482 51

Abstract:

An improved lift apparatus for use in a treadmill having a support base and a treadbase is disclosed. The lift apparatus includes a lift motor assembly linked to the support base and to a cam. The first cam can be attached to a torsion bar linked to the support base. An incline link bar is linked to the first cam and to the treadbase. The force generated by the motor assembly is efficiently translated from the cam to the treadbase, thereby inclining the treadbase.

Appl. No.:

11/178715

Inventors:

Richard Allen Compton - Colorado Springs CO, US
Gerald Daines Nelson - Colorado Springs CO, US

Assignee:

ICON IP, Inc. - Logan UT

International Classification:

A63B 21/062

US Classification:

482103, 482138

Abstract:

An exercise apparatus includes a support structure having a base portion, the support structure housing a resistance assembly (e. g. , including a weight stack). At least one arm assembly is mounted to the support structure. Each of the one or more arm assemblies includes: (i) an elongate member, and (ii) a mounting bracket assembly. The mounting bracket assembly is pivotally mounted to the elongate member and also pivotally mounted to the support structure at a location spaced apart from the base portion of the support structure. One pivot mount allows the elongate member to pivot up and down, while the other pivot mount allows the mounting bracket assembly (and thus the arm assembly) to pivot in and out (i. e. , laterally). At least one cable extends from the resistance assembly to the at least one arm assembly.

Appl. No.:

7/601906

Bart T. Lynam - Edmonds WA

International Classification:

C05F 700
C02F 1100

US Classification:

71 12

Abstract:

A method of converting industrial, domestic or other sludge, into a pelletized or granular fertilizer, as well as a sludge converter for practicing the method. The sludge is dewatered to form sludge cake solids which are dried in a dryer, and then sorted with a sorter into a sorted product comprising oversized, undersized, and standard sized product. A portion of the sorted product is recycled for mixing and sizing in a mixer with the dewatered sludge cake solids. To control dust and odors, cyclones and a condenser remove a substantial portion of the gaseous particulate matter and condensable gases from the converter, and any remaining noncondensates are burned in the heat source flame. A waste oil burning heat source supplies heat energy to the dryer. The heat source exhaust gas by-products are filtered in a bag house using a conditioner additive, such as lime or sodium bicarbonate, which may be reclaimed and supplied to the standard sized product to serve as a pelletizing binder, to enhance the fertilizer nutrient value, or to enhance the fertilizer shelf life.
