Assignee:

CARL Manufacturing USA, Inc. - Mount Prospect IL

International Classification:

B26D 1/18

US Classification:

83522, 83614, 83955

Abstract:

The combination of a base, with which at least one sheet layer can be operatively supported to be cut, a guide assembly, and a cutting blade assembly. The cutting blade assembly includes first and second cutting blades. The cutting blade assembly is selectively changeable between a) a first state wherein the first cutting blade is in a first operative position and the second cutting blade is in a first inactive position, and b) a second state wherein the second cutting blade is in a second operative position and the first cutting blade is in a second inactive position. The cutting blade assembly cooperates with the guide assembly to be movable guidingly in a cutting path.

Appl. No.:

10/429061

Inventors:

Richard J. Schultz - Barrington IL, US
Hideki Koto - Yotsukaido, JP

Assignee:

CARL Manufacturing USA Inc. - Mount Prospect IL

International Classification:

B26D 1/18

US Classification:

83485, 83614

Abstract:

The combination of a sheet cutting apparatus and a tool. The sheet cutting apparatus has a base with a surface for supporting a sheet material operatively positioned upon the base. A rail assembly on the base has a length. The sheet cutting apparatus further includes a blade assembly. The blade assembly has an operative state in which the blade assembly is movable guidingly in a cutting path along the length of the rail assembly to make a cut in a sheet material operatively positioned upon the base, and is repositionable relative to the rail assembly from the operative state into a separated state. The tool is operable by a user to facilitate repositioning of the blade assembly from the operative state into the separated state.

International Classification:

G05D011/00
G05B011/01

US Classification:

700/282000, 700/017000, 210/141000

Abstract:

In one form of the present invention, the operation of reducing hard water to soft is controlled via integrated circuits and software. In combination as a computer control unit, the integrated circuits and software control a valve that supports the cycles used in softening water. The invention reduces the complexity of the setup and operation of a water softener using four simple keys in conjunction with the computer control unit. In addition to these four simple keys, a hidden key is also provided for internal use in manufacturing and servicing operations. The hidden key may have no graphic or identity on the interface panel of the computer control unit, or it may have some graphic not indicative of a key. When depressed along with other keys, this hidden key offers a way to access special operations such as data input and output.

Appl. No.:

8/106304

Assignee:

R. M. Schultz & Associates, Inc. - McHenry IL

International Classification:

B65B 104
B65B 304

US Classification:

141197

Abstract:

An automatic filling system for a compressed gas tank includes a controller that measures the rate of fill of a tank being filled in order to provide an accurate estimate of the fill time for the tank, given available source pressure. Compressed gas flow is controlled with on/off valves that are driven open by a motor/gearbox/clutch combination to reduce thermal and physical shocks associated with opening of the valve. Whenever power is removed from the clutch, a spring automatically drives the valves closed quickly to provide fail-safe operation.

US Patent:

Filed:

Oct 25, 1978

Appl. No.:

5/954517

Inventors:

Richard M. Schultz - Oakwood Hills IL

Assignee:

Honeywell Inc. - Minneapolis MN

International Classification:

G08B 2900
G06F 700
H04Q 500

US Classification:

340506

Abstract:

A security system for supervising the integrity of a communication line having a supervising apparatus which generates first and second random signals, compares these first and second randomly generated signals to provide a third signal and compares this third signal to a fourth signal, and a transponder, also connected to the line, which compares the first and second randomly generated signals to provide the fourth signal to the communication line. The use of randomly generated signals increases the difficulty of breaching line security such that, when the supervisory apparatus detects a difference between the third and fourth signals, it can provide an appropriate alarm, indication, or control.

US Patent:

Filed:

Apr 7, 1975

Appl. No.:

5/565953

Inventors:

Richard A. Schultz - Houston TX

Assignee:

BJ-HUGHES Inc., formerly Byron Jackson, Inc. - Houston TX

International Classification:

E21B 1914

US Classification:

214 25

Abstract:

Apparatus for stabbing casing pipe as the casing is being run into a well bore. It includes a casing handling head arranged for grasping a generally upright section of casing pipe near the upper end thereof. The head is controllable for movement in a horizontal plane extending over the well bore and is movable vertically also. An operator platform is attached to the head for movement therewith. The platform has control means mounted thereon for operating the head, whereby an operator supported on the platform can visually observe and guide stabbing of a section of casing pipe and release the same by operating the control means. The position of the platform is such that an operator supported thereon can carry out other manipulative steps associated with the casing stabbing operation, as for example, the operation of the elevators, the pipe slings, and the like.
