Title: Method for improving the performance of a water gun seismic source array including guns of different volumes
Inventor: SAFAR DR MO HUSSAIN
IPC: G01V1/02
Filed: 1987-04-29
Abstract: The performance of the far field pressure signature radiated by the water gun is improved by implementing either one of the following methods. The first method involves firing a water gun sub-array, which consists of a single P400 water gun and three S80 water guns. The second method involves firing a water gun sub-array, which consists of two water guns, a P400 and an S80, sequentially three times once with P400 and S80 water guns simultaneously and then twice with S80 water gun only. The effective far field pressure signature radiated by the second sub-array is obtained by summing the three far field pressure signatures obtained as outlined above. A P400 water gun has a firing chamber of 400 cu in and two ports and an S80 water gun has a chamber of 80 cu in and four ports.

Title: A removable short-circuit device for use in a photo-electric tube
Inventor: HERMITE PIERRE L
IPC: H01H37/76
Filed: 1987-07-17
Abstract: A short circuit device removable by spring action, has the form of a metal loop having a base side (11) forming a first terminal contact, from which alongside (12) and a short side (13) extend substantially parallel to one another, the end (14) of the long side (12) forming a second movable contact for completing an electrical circuit with a stationary contact member. The long and short sides are rigidly connected by a connection side (15), completing the loop, at least the long side being under spring force which, when the connection side is broken e.g. by radiation 40, moves the end (14) of the long side with respect to the base side so as to break the electrical circuit. The invention is applied to the manufacture of photoelectric tubes, in which the short circuit device allows two adjacent dynode leads to be used to heat a cathode evaporator. The short circuit is then removed for normal use.
