US Patent:

42522838, Feb 24, 1981

Filed:

Jan 15, 1979

Appl. No.:

6/003298

Inventors:

William H. Maxwell - Los Angeles CA

Assignee:

Time & Temperature Company - Los Angeles CA

International Classification:

B65H 1704

US Classification:

242 671R

Abstract:

A thermograph adapted to be pre-loaded with chart paper upon which shipping information can be written, and comprising an instrument unit enclosed in an expendable container for automatic operation and security assured by a seal, the instrument being electro-mechanical wherein solid state circuitry horoligically controls a prime mover to advance the chart on a time basis and including a chassis over which the chart is guided onto a spool journaled therein, and a spool drive carrier depending from the chassis and keyed into alignment with and having a motor and gear drive to the spool.

Harvey J. Sines - Los Angeles CA

Assignee:

Time & Temperature Company - Los Angeles CA

International Classification:

G01K 102
G01K 570

US Classification:

733435

Abstract:

A thermograph adapted to be pre-loaded with chart paper upon which shipping information can be written, and comprising an instrument unit enclosed in an expendable container for automatic operation and security assured by a seal, the instrument being operated horologically in combination with a thermometer and all of which is electro-mechanical wherein solid state circuitry powers prime movers to advance the chart on a time basis while servo positioning a recording stylus by means of interval pulses, and responsive to a temperature sensing transducer means cooperating with the solid state circuitry comprised of a comparator means, and discriminator means operable to actuate switch means to "power-up" or "power-down" prime movers that position said stylus according to temperature sensed by said transducer means.

RE321087, Apr 8, 1986

Filed:

Jun 10, 1981

Appl. No.:

6/272317

Inventors:

William H. Maxwell - West Los Angeles CA

Assignee:

Time & Temperature Corporation - Ventura CA

International Classification:

G01K 102

US Classification:

374186

Abstract:

A thermograph for automatically recording variations of temperature correlated with the passage of time and characterized by a light weight and durable construction protectively combined with a shipping container which serves as a housing enclosing the instrument while exposing a heat transfer element for quick response and a direct recording of prevailing temperature upon a chart. The instrument is a permanent and reuseable unit that is carried within the expendible shipping container to produce a thermogram from a prepared chart of pressure sensitive material that is transported over a thermometer stylus by means of a clock motor drive.

Filed:

May 17, 1974

Appl. No.:

5/470901

Inventors:

William H. Maxwell - West Los Angeles CA

Assignee:

Cargo Graphics Corporation

International Classification:

G01D 910
G01K 570
B65D 8538

US Classification:

346 33TP

Abstract:

A time temperature recording device especially adapted to the business of transporting perishables and characterized by a preloaded returnable instrument of permanent nature packaged in a protective liner held secure and warranted by a sealed box that is expendible, with separate access openings for exclusive use of shipper and receiver respectively, and wherein a logic means permits depression of a stylus onto a pressure sensitive chart when instrument operation is started by the shipper, and lifts said stylus and releases said chart when stopped by the receiver. The used instrument is especially adapted to be returned by the Postal Service.
