OMM-PAH-PAH—Walter Logan, who makes and repairs glass equipment for the University, is shown working in his shop in Bailey hall. Mr. Logan has done this delicate type of work for many years. His reputation is so firmly established that occasional requests for work comes from any places other than departments of the University.
250 AFROTC Students Fly In Olathe Training Program
By RON GRANDON
About 250 Air Force ROTC cadets have flown Olathe Air base planes so far this year in a flying indoctrination program of the campus AFROTC
Col. Thomas B. Summers, profes- $ ^{ \textcircled{3}} $
sor of air science and tactics, said all of the cadets who have flown at stairs in the past. "Three hours in the air. 'On long trips all the boys get a chance to sit in the co-pilot seats and handle the controls,' he said.
Purpose of the program. Col Summers said, is "to acquaint the cadets with what it means to fly."
A typical trip for the cadets includes observation of every stage of the flight including mission briefings and the final report.
The first detail of the pre-flight planning includes a check with the weather department to check the latest weather maps which show cross winds, air currents, and amount of overcast.
Then the trip is drawn on the map with a line called a "magnetic heading" showing the true compass bearing and the air waves which the line crosses are estimated for speed and direction.
Then the flyers take a quick briefing on what is called a "radio facilities chart" which tells the number and location of airports in any specific area, the radio or "beam" frequency of these airports, and the identification signal of these fields.
Stages of the flight are put on "planning cards" and these cards are taken to the operations officer for clearance. Next the cards are taken to the flight control department, composed of officials from the Air Force and the Civil Aeronautics administration, to get final clearance. Here the pilot must specify altitude and is given certain check points which he must contact during the flight.
This usually winds up the preflight planning, and, according to Col. Summers, it is within the next three hours when the cadets really find out whether they like to fly.

KU Has Its Own Glassblower
By VALERA TEBBEN
Walter Logan, 1747 Tennessee, glassblower for the chemistry department, makes and repairs all the complicated glass equipment used in the chemistry department as well as other departments on the Hill.
Working one summer as an apprentice, Mr. Logan learned the fundamentals of the art from Mr. Fred Rustenback, who for 20 years had been glassblower for the chemistry department. Since he was leather-leased by experience, and now he can make almost anything.
Considerable patience and skill is required in heating and blowing the glass to exact proportions and shapes. The glass must be heated to the precise degree of melting, and manipulated and blown at the exact instant when these operations can best be done.
"The most important thing to consider when working with glass is to know what parts to put on first, so that the other parts will not crack when heat is applied." Mr. Logan explains, "the size, must be considered in relation to their rate of expansion when heated."
Working from sketches or drawings which give the required dimensions, Mr. Logan relies on his own knowledge and skill to accomplish the task.
Pyrex tubes come ready-made, as small as 2-100 mm in diameter and approximately 2 feet in length. Joints (smaller and shorter tubes) also come in sizes, as do the ball and socket joints.
A small rotary, power-driven glass saw is used to cut the glass tubing to the required length. During this process, a white, milk-like liquid (soluble oil mixed with water) is allowed to run on the glass. This cools the glass and aids the cutting process. Without its use, the saw would only scratch the glass.
A blast lamp is used for heating and melting the glass. Oxygen and natural gas are used to heat soft glass or pyrex. However, to heat quartz glass, which is very hard, hydrogen and natural gas are used because this combination gives a much hotter flame. A hydrogen-fed flame is so hot that dark goggles must be worn to protect the eyes.
After the glass has been "worked," it is placed in a large annealing oven and left overnight at a temperature of 510° C. (more than twice as hot as the same degree of heat in Faren-
heit, with which most of us are more familiar). In the morning, the heat is cut off but the glass equipment left inside to cool gradually as the oven cools. This process takes the "strain" out of the glass, preventing its breaking if some parts should cool more rapidly than others.
For example, when a ring seal is placed on a glass tube (a process similar to welding two pipes together), the glass in the seal area is thicker at that point than is the rest of the tube. If the glass were not left in the oven to cool very slowly, the thin portion would cool faster than the ring portion, and would break.
Several KU graduates now located at other colleges send orders for both new and repair work to Mr. Logan. He is paid for the work and then reimburses the University for the material used.
Danforth Business Trend Lots of Weddings Coming Up
For the couples who wish to be married on the campus, the only problem involved in securing the chapel is to make the reservations at least three months in advance. The reservations, which are free, are made through the registrar's office. They are available to all students who have attended the University, faculty members, and employees.
Since the chapel was built in 1946, 441 couples have marched down its walls. And now, in Dunfortshire he become a symbol—a climax to campus romances.
The evidence of spring is everywhere—but the most obvious sign is the bustling activity in Danforth chapel. The traditional April-May-June rush on weddings has begun.
The spring demand on the chapel makes the scheduling of four ceremonies in one day not uncommon.
In its matrimonial history, the chapel has been tested in many ways. The seating capacity of 96 is frequently overlooked by guests as the well-wishers stand, crowd in or simply wait outside. Oriental trees have been erected as decorations and candles have been placed in every possible place. Several weddings were even held in the chapel before it was completed.
