Teachings of Weiland
Weiland's invention concerns ultrasound apparatus for determining whether a
female large animal, especially a cow or a mare, is gravid. The ultrasound apparatus,
as shown in Figures 1-2, consists essentially of an ultrasonic head 1, a handle 2, an
extension 3 of the handle and equipment 4.
The ultrasonic head 1 consists of a circular cylinder 5 with a piezo-oxide disk 6.
On each side of the disk are the active components of an ultrasound transmitter 7 and
an ultrasound receiver 8, and between piezo-oxide disk 6 and the free end of cylinder 5
is an intermediate 10 with an area equaling the open cross-section of the cylinder 5.
The surface of intermediate 10 facing disk 6 fits tight inside cylinder 5. There is a filler
11 on the side of piezo-oxide disk 6 facing away from intermediate 10. An electric
cable 12 that connects to ultrasound transmitter 7 and receiver 8 extends through filler
11. The bottom of cylinder 5 is closed off with a circular plate 13.
A narrower threaded section 14 of handle 2 extends through a bore 15 in the
surface of cylinder 5 and into space 16 between filler 11 and plate 13. Screwed onto
