Abstract
Abstract A system for controlling the filling of a storage tank with a fluid in which the storage tank normally is provided with a sound transmitting device activated when the fluid reaches the level of the sound transmitting device. The system includes a time delay for continued feeding of fluid to the storage tank, the time delay being controlled to permit the void in the storage tank above the level of the sound transmitting device to be filled with fluid to the maximum capacity of the tank.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
174 words
A fluid delivery apparatus for maximum filling of a tank from a supply vehicle, the tank having a vent pipe with a whistle device therein which ceases to whistle when the fluid in the tank reaches a preset level, the apparatus comprising: a fluid feed pipe from said supply vehicle, a delivery spout on the end of said feed pipe for insertion into the tank, a trigger shut off valve on the end of said feed pipe, an operating means for closing said shut off valve, a microphone located on the end of said feed pipe connected to an amplifier means said amplifier means connected to said operating means and adapted to produce a signal representing the whistle from said tank and prevent said operating means from closing said shut off valve while said amplifier produces said signal, and a time delay means operatively coupled to said operating means so as to prevent said operating means from closing said shut off valve for a predetermined time after the signal from the amplifier means terminates.
Claim 2
Dependent Claim
174 words
A fluid delivery apparatus for maximum filling of a tank from a supply vehicle, the tank having a vent pipe with a whistle device therein which ceases to whistle when the fluid in the tank reaches a preset level, the apparatus comprising: a fluid feed pipe from said supply vehicle, a delivery spout on the end of said feed pipe for insertion into the tank, a trigger shut off valve on the end of said feed pipe, an operating means for closing said shut off valve, a microphone located on the end of said feed pipe connected to an amplifier means said amplifier means connected to said operating means and adapted to produce a signal representing the whistle from said tank and prevent said operating means from closing said shut off valve while said amplifier produces said signal, and a time delay means operatively coupled to said operating means so as to prevent said operating means from closing said shut off valve for a predetermined time after the signal from the amplifier means terminates.
Claim 3
Dependent Claim
52 words
The fluid delivery apparatus as set forth in claim 1 including a setting dial adapted to be set to indicate the capacity of the tank to be filled, the setting of the dial controlling said time delay means and thus the predetermined time before the operating means closes said shut off valve.
Claim 4
Dependent Claim
30 words
The fluid delivery apparatus as set forth in claim 1 including a battery power source located on the end of said feed pipe for said amplifier means and operating means.
Claim 5
Dependent Claim
35 words
The fluid handling apparatus as set forth in claim 1 including a further preset time delay to prevent said operating means from closing said shut off valve, when said shut off valve is first opened.
