Spencer Publishes

Brochure On Gas And

Diesel Engine Heads

A brochure issued by Spencer

Heads, Inc., Gladewater, Texas, de- scribes its "engineering breakthrough for the prevention of diesel and gas cylinder head-cracking."

The patented Spencer "Adapted"

Head extends the engineering prin- ciple of separating the greater com- bustion temperature and expanding cylinder head from the lesser expan- ding block or cylinder.

Spencer Heads' system goes a step further in engineering by manufac- turing a "head within a head" with free-expansion "stress-area inserts" to eliminate stress points on combus- tion faces of heads which otherwise are susceptible to cracking.

Approximately 98 percent of head- cracking occurs through or between the spark plug openings and the valve opening. The Spencer system relieves this known stress spot by covering it only with a "Stress-Area Insert."

Hot spots or stress areas are the vul- nerable spots where head-cracking occurs on head after head. This is because of the narrow water-jacket passageway which restricts the com- bustion heat from being dispelled into the water sufficiently. This concen- trated head build-up results in un- even expansion in this area and, just as a wire bent back and forth, it later breaks.

Spencer System provides for coun- terboring a head with a known stress area to a sufficient diameter and depth to allow for a stress area insert having a threaded boss screwing into a threaded hole in the counterbore.

The stress area insert is .030 of an inch smaller in diameter than the counterbore in which it nests. The stress area insert absorbs this exces- sive heat and is free to expand to the gap. As a result, the counterbored insert-covered floor of the head now expands uniformly with the rest of the head—the stress has been elimi- nated.

PRE-ADVANCE NOTICE TO BIDDERS 15 Cubic Yard

Dipper Clamshell Dredge for

Panama Canal Company (Serial No. PC-73-50)

The Panama Canal Company, a corporate agency and instru- mentality of the United States of America, is planning to request bids for the construction and delivery of a non-self propelled diesel-electric powered 15 cubic yard dipper dredge, capable of excavating 60 feet below water level, with an 18 cubic yard clamshell option. The formal request for bids will be distributed on or about March 30, 1973; the bids will be opened on or about

August 31, 1973 and will require construction and delivery in the Panama Canal within two years.

The basic design envisions a modified in-production model, self contained shovel-dragline machine, mounted on a suitably ar- ranged barge hull, and adapted for sub-surface excavation. All main and auxiliary power will be supplied by a diesel-electric plant utilizing proven production model engine generator sets.

Adequate winches, spuds and related equipment will provide a modern dredge with ready sources of procurement for normally required replacement parts. The dredge will be equipped with a machine shop and air conditioned day quarters for a crew of 1 1 men.

The basic specifications will be:

Length overall (over sponsor and fenders) 154'

Breadth overall (over fenders) 73

Depth (maximum) 16

Length of boom 65'

Total rating of prime movers 4500 hp

The estimated price range is $3,000,000 to $5,000,000.

An Advance Notice to Bidders will be issued prior to advertise- ment of the project by the Contracting Officer, Engineering and

Construction Bureau, Panama Canal Company, Balboa Heights,

Canal Zone. At that time, sets of drawings, together with speci- fications, will be furnished upon receipt of a deposit of $100 per set.

The Captain is happy

Public Correspondence stations are deiighted (WJG-Memphis and WGK-St. Louis)

WJG says: "The operation of the SE-IX Encoder has been unfailing in its purpose. We can call vessels at any time we desire. As more ships are getting the

SD-VI Decoders installed, we are having less and less trouble contacting them."

Terrence B. Miller, President,

WJG Radio, Inc.

Who wants to listen to SSB radio chatter?

Now the Captain can receive SSB radio- telephone calls, au- tomatically. No voice monitoring is neces- sary. He can receive calls on 6 channels.

The home office is happy

They have an Encoder installation. Calls go direct, to each De- coder-equipped boat.

Just select the 5-digit code of the called boat on the Encoder and press the transmit but- ton. Calls go through SE.IX ENCODER in 2 seconds.
