Title: Turbine wheel flow measuring device
IPC: G01F9/00
Filed: 1981-04-08
Abstract: The subject matter of the invention is an impeller flow-meter, particularly for accurate measurement of the flow rate of liquid fuel fed to an internal-combustion engine. In the flow-meter according to the invention, an impeller chamber (1) is provided with an inlet pipe (2), surrounded coaxially by an ante-chamber (3). A supply pipe (4) is provided for the liquid fuel and an offtake pipe for excess fuel, these pipes being situated in different planes along the axis of ante-chamber (3). A space (6) is located between the entrance end of inlet pipe (2) and the exit end of supply pipe (4). A slot (7) is formed between the outer wall of inlet pipe (2) and the inner wall of the coaxial ante-chamber (3). The slot (7) communicates with space (6) and offtake pipe (5). As a result of this structure, pulsations in the liquid supply, which would affect the impeller accuracy, are substantially extinguished in space (6) before reaching the impeller chamber (1).

IPC: B65H23/188
Filed: 1981-10-06
Abstract: Method and apparatus for controlling tension in a 
longitudinally moving web of material between fixed mate­
rial feeding points, while maintaining the length of the path 
of the movement between said fixed points substantially 
constant. A pair of axially fixed material-feeding rollers are 
positively driven from a common drive motor, with one of 
the rollers being driven at a variable rate of speed through a 
roller shaft-mounted transmission unit having a variable 
pitch pulley located thereon at a spaced distance from the 
axis of rotation of the roller shaft. The variable pitch pulley is 
connected to the motor drive pulley by a flexible belt, and 
fluid piston means is provided for applying a constant force 
on the transmission means in a direction about the axis of 
the roller shaft to impose a constant torque on the variable 
speed roller, and to move the transmission unit with its 
variable pitch pulley about the axis of rotation of the shaft to 
increase or decrease the speed of the feed roller, thereby 
maintaining a constant imposed tension on the material in its 
fixed length path of movement of the material between the 
rollers.  
     In a further embodiment, variations in tension on the 
material upstream of the positively driven feed rollers is 
controlled by provision of a displaceable roller which 
engages the material upstream of the first feed roller and is 
displaced in response to upstream tension variations to 
impart a corresponding force to the transmissions unit to 
rotate the same about the roller shaft axis and correspond­
ingly vary the speed of rotation of the roller to maintain a 
substantially constant total tension on the material in its 
fixed length path of movement between the rollers.

infrared radiation. Electrical energy is generated by the solar 
cell or cells when irradiated. The primary circuit of the power 
supply includes a plurality of infrared emitting diodes (2) which 
are energised electrically to provide infrared radiation. The cur­
rent produced by the solar cell or cells in response to the radi­

adjacent portion of the pipe wall, in such a way that it causes 
both dispersion of the accumulations (11, 12) and rotation of 
the material around the circumference of the pipe. The 
invention is particularly applicable in the oil industry.

Abstract: Pump means for pumping a multi-phase flow consisting 
of a mixture of gas, liquid and finely-divided solid material 
with a variable mutual ratio of mixture. The pump means 
primarily comprises a pump housing (1) with an enclosed 
rotating drum (4). In the end walls (2,3) of the pump housing 
(1) there are arranged connection openings (15,16,21,22) for 
the supply and discharge of a driving fluid and a pump flow, 
respectively. The drum (4) comprises several cylinder spaces 
(5,6) arranged in axially aligned pairs with all the pairs con­
centrically arranged inside the envelope surface of the drum 
(4). The cylinder spaces (5,6) of each pair are separated by 
means of a partition (12). In the cylinder spaces (5,6) of each 
there are arranged a drive piston (7) and a pump piston (8) 
interconnected by a piston rod (9) passing in a sealed manner 
through the partition (12). During the rotation of the drum (4), 
a driving fluid is supplied to one side of the driving side and 
acts on the drive piston (7) connected to the pump piston (8), 
whereby a pump flow is pressed out with the pump piston (8) 
from one side of the pump side whereas driving fluid from 
the other side of the driving side is discharged and pump flow 
is supplied to the cylinder space on the other side of the pump 
side. With this type of pump means a pump is obtained which 
comprises few movable parts and which, in spite of the fact 
othat it is relatively slow moving, has a high pump capacity.
