Abstract
Abstract A stream-type liquid blending system utilizes a number of flow loops, one for each of the components which it may be desired to blend; the flow loops are each capable of being connected (by way of remotely-controlled block valves) into either one or the other of two blending headers. Each flow loop has associated therewith percent switches which are manually set to establish (by operation of the block valves) to which header a given flow loop is connected, and also to set the percentage of the given component in the blend. The blend flowrate and the preset quantity of a blend can be set individually for each header. An air blowing system functions at the end of a blending operation to force the remaining blended liquid out of the header, and a blowback system associated with each loop blows most of the liquid component in such loop back toward the tank wherein it is stored.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
82 words
Stream-type liquid blending apparatus comprising a pair of independent blending headers, a plurality of flow loops, means for circulating a respective liquid blending component through each of said loops, separate controllable means coupled to each of said loops for causing the corresponding blending component to be fed into either of said headers, and manually-operable means for selectively operating the controllable means of each loop, thereby to cause the corresponding blending component to be fed into a selected one of the two headers.
Claim 2
Dependent Claim
82 words
Stream-type liquid blending apparatus comprising a pair of independent blending headers, a plurality of flow loops, means for circulating a respective liquid blending component through each of said loops, separate controllable means coupled to each of said loops for causing the corresponding blending component to be fed into either of said headers, and manually-operable means for selectively operating the controllable means of each loop, thereby to cause the corresponding blending component to be fed into a selected one of the two headers.
Claim 3
Dependent Claim
24 words
Apparatus of claim 1, wherein the manually-operable means is also operable to select the percentage of the blending component fed into the selected header.
Claim 4
Dependent Claim
50 words
Apparatus according to claim 1, wherein the manually-operable means comprises a pair of switches for each loop, one switch of each set of paired switches being associated with one of said headers and the other switch of each set of paired switches being associated with the other of said headers.
Claim 5
Dependent Claim
43 words
Apparatus of claim 3, wherein one switch of each set of paired switches is connected to receive control pulses for said one header, and the other switch of each set of paired switches is connected to receive control pulses for said other header.
Claim 6
Dependent Claim
27 words
Apparatus set forth in claim 4, wherein each of the switches comprises percent switches manually settable to pass a selected percentage of the control pulses applied thereto.
Claim 7
Dependent Claim
32 words
Apparatus according to claim 1, wherein the controllable means comprises a pair of block valves for each of said loops, coupled between the corresponding loop and respective ones of the two headers.
Claim 8
Dependent Claim
17 words
Apparatus of claim 6, wherein the manually-operable means is arranged for selective operation of said block valves.
Claim 9
Dependent Claim
24 words
Apparatus of claim 7, wherein the manually-operable means is also operable to select the percentage of the blending component fed into the selected header.
Claim 10
Dependent Claim
51 words
Apparatus set forth in claim 6, wherein the manually-operable means comprises a pair of switches for each loop, one switch of each set of paired switches being associated with one of said headers and the other switch of each set of paired switches being associated with the other of said headers.
Claim 11
Dependent Claim
43 words
Apparatus of claim 9, wherein one switch of each set of paired switches is connected to receive control pulses for said one header, and the other switch of each set of paired switches is connected to receive control pulses for said other header.
