IMPROVED TONSIL TRACTORS

An Improved Method of Using the Tonsil Guillotine

operations are now distinguished, viz., tonsillotomy, in which only a slice of the enlarged tonsil is removed, and tonsillectomy, in which the whole tonsil is removed with its capsule intact. The former operation is carried out with a guillotine, the latter by dissection. The merits or demerits of the rival operations I do not propose to discuss. To those interested in the question, both sides ...

Slicot Drives Tractors! 1

We describe the successful application of a SLICOT subroutine in a control engineering problem. Based on GPS data it is possible to automatically steer farm vehicles along a prescribed trajectory. The bottleneck for the successful on-line implementation of a LQG regulator is the numerical solution of a discrete-time algebraic Riccati equation in real-time and at high accuracy. This is achieved ...

Tonsil fibromatosis.

Fibromatosis is a non-metastatic, however locally invasive tumor that may infiltrate muscle, fat, and bone. It may be fatal depending on its location. Tumors in the head and neck are particularly dangerous. These fibroblast tumors have poorly defined margins and are not encapsulated. Anaplasia and invasion of nerves and vessels are not present; mitosis is rare and there may be collagen between ...

Power Hop Instability of Tractors

Power hop is a “porpoising” type of pitch/bounce oscillation superimposed on the forward motion of tractors equipped with pneumatic tires. It is most often observed with tractors having two powered axles pulling towed implements in moderate to high draft field operations on dry soils. As power hop begins, the tractor exhibits gradually increasing vibration amplitudes until the operator, of nece...
