Filed:

Mar 16, 1993

Appl. No.:

8/033176

Inventors:

Robert L. Jenkins - Coatesville PA
George F. Wilkins - Norristown PA
Michael J. Noone - Wayne PA
Norman M. Robinson - Coatesville PA
Robert E. Oglesby - Downingtown PA

Assignee:

CertainTeed Corporation - Valley Forge PA

International Classification:

B32B 3100

US Classification:

156277

Abstract:

A composition roofing shingle is described which has release material affixed thereto for the purpose of identifying the compositional shingle with process parameters for the time frame of manufacture. The identification is achieved by marking the release material with planographic idicia by means such as printing, stamping and ink-jet spray application.

International Classification:

US Classification:

27126502

Abstract:

An apparatus for determining the dimensions of a stack of sheets in the tray. An optical sensor is arranged so that movement of the sheet guides in a paper tray causes a variably graduated scale to be moved past the sensor. The sensor may either be a transmissive or reflective type analog sensor in which the strength of the signal generated by the sensor is converted into a position of the side guides and as the analog scale is continuously variable, there is no need for separate discrete sensors or switches and sheet sizes of any dimension can be accommodated. A recalibration process is used to prevent contamination of the gauge and the associated change in signal strength by this sensor from causing the size determinations to be inaccurate. Alternatively, a digital sensor in cooperation with a digital bar code or other digital scale can be utilized to determine the variable sheet size, which digital sensor and variable scale are insensitive to contamination by dirt or paper particles, etc. The sensor system herein is very robust and provides a simple device for determining the size of a stack of sheets in a paper tray.

Appl. No.:

7/924430

Inventors:

Norman M. Robinson - Coatesville PA

Assignee:

CertainTeed Corporation - Valley Forge PA

International Classification:

E04D 100

US Classification:

52518

Abstract:

A shingle or other roof covering is provided, comprising a tab portion and a butt portion. The shingle surface is provided with a band zone, in which adhesive zones are applied. The band zones run the entire width of a shingle, and are preferably located either on the underside surface of the tab portions, or on the top surface of butt portions The adhesive pattern is so that shingle lifting due to wind is resisted, but so that moisture can escape between overlapped shingles when the adhesive secures them together.

Filed:

Appl. No.:

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B41F 1354
B65H 3304
B65H 344

US Classification:

270 11

Abstract:

An improved system for segregating and identifying separate job sets from a commonly stacked output of plural job sets of copy sheets sequentially generated by a printer and sequentially outputted into a sheet stacker in which they may be superposed commonly stacked. A control system selects which standard size sheet supply tray of the printer will feed the copy sheets for a selected job set, and can automatically feed and print a cover sheet of a larger size or different orientation before or after the job set copy sheets are fed. The sheet stacker may desirably stack the copy sheets of the job sets commonly edge aligned but so that at least one edge area of the cover sheets extends substantially from at least one edge of the stack of copy sheets of the job sets to provide an exposed printed banner strip for clear job sets segregation and separation even if the commonly stacked plural job sets of copy sheets are misaligned in subsequent handling. The cover sheets may be printed side up even if the job set copy sheets are stacked printed side down. The exposed banner strip may have identifying indicia printed thereon for identifying job sets.

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B65H 304

US Classification:

271 34

Abstract:

An apparatus in which the approximate thickness of a set of sheets is determined. A tray supporting a stack of sheets thereon is periodically indexed a preselected distance each time the thickness of the stack of sheets decreases by a specified amount. The approximate thickness of the set of sheets is calculated as a function of the number of times the tray is indexed and a constant corresponding to the preselected distance the tray indexes.
