Philadelphia Section SNAME Meeting

Some 70 members and guests attended the recent meeting of the Philadelphia Section of The

Society of Naval Architects and

Marine Engineers held at the En- gineer's Club in Philadelphia.

Following opening announce- ments by section chairman K.

Gyswyt, the nominating commit- tee presented its slate of officers for next season as follows: chair- man, James J. Hibbits, General

Electric Company; vice-chairman,

Thomas P. Campbell, Sun Ship; secretary-treasurer, Dean S.

Champlin, Selby Battersby & Com- pany ; member of Executive Com- mittee, Mr. Gyswyt.

The Henschel Digital Master

Clock System provides a syn- chronized display of time in various shipboard locations. The master clock displays both local time and Greenwich Mean Time (GMT).

This crystal controlled, microcomputer based master clock transmits multiplexed time (hours, minutes and seconds) and date (month, day and year) information to a maximum of 40 remote repeater clocks and/or data and bell loggers.

The remote repeater clocks display either local time or GMT in various mounting configurations to suit most applications.

Time is continuously displayed on both the master and repeater clocks by red, 6 digit LED displays, easily viewed up to 25 feet away. The date is displayed on the master clock by use of a front panel switch. This calendar function is set to maintain the correct date for changes in month, day, year and leap year.

Battery back-up is provided to maintain both time and date in the master clock and in a few selected repeater clocks during any loss of input power.

Clock accuracy is maintained independent of the input power frequency by a self-contained crystal oscillator. Time and date are easily set by means of pushbuttons on the front panel. When changing time zones, hours may be changed independently of minutes and seconds so that time accuracy is not lost. ®

Telephone: 617-388-1103, Telex: 94-7444 son, meeting coordinator, who in- troduced Albert W. Forrest Jr. of

Sun Ship, co-author of the paper titled "Shaft Alignment Using

Strain Gages." A detailed descrip- tion of the strain gage shaft alignment procedure was pre- sented, including a comparison be- tween bearing reactions obtained using strain gages and hydraulic jacking.

The author discussed the vari- ous gage configurations available for measuring bending moments, and gave estimates of the result- ing error in bending moment. A simplified procedure was pre- sented to calculate bearing re- actions for the measured mo- ments. Gage site requirements to produce a determinate system were established, and a method outlined to establish bearing re- action error bounds for a combi- nation of gage configurations and sites.

The interest in this subject was evident by the varied opinions of the discussers, who were: Frank

Graham, Philadelphia Gear, Inc.;

Bud Thoma, Transamerica De- laval, Inc.; and George Laing,

General Electric Company.
