Title: Apparatus for blending stock for a paper machine
IPC: D21F1/08
Filed: 1969-08-04
Abstract: The flow of fluid stock to be mixed in the blend chest 10 of a papermaking machine is automatically varied in dependence on its consistency, so that the ratio of stock components in the blend, on a dry mass basis, does not vary with the consistency of the component fluid stock. As described, softwood fibre stock, hardwood fibre stock, brokes and an additive (e.g. alum) are supplied to the blend chest 10 through pipes 48, 54, 58, 62 respectively, and the respective consistencies are measured by detectors 52, 56, 60, 64. A computer calculates the required flow rates of the four components, using signals from the detectors, the required total flow rate F D (determined by a level detector 16) and the desired stock proportions R A , R B , R H , R S (on a dry mass basis). The individual flow rates are controlled by feedback loops 30, 32, 34, 36, of which the loop 30 is shown in more detail. A flow detector 50 supplies a signal which is compared with the desired signal Fs and an error signal on line 42 controls a regulator 44 for a valve 46.

Patent ES-404512-A1 (ES)
Title: Air-cooled internal combustion engine with speed control
IPC: F02D9/02
Filed: 1972-07-04
Abstract: Air blown over the cooling fins on a cylinder of an internal combustion engine by an engine-driven blower moves a spring-loaded vane away from a position of abutment against the fins. The vane is linked to a throttle valve in the intake pipe for the fuel mixture and is located on the same side of a reference plane through the cylinder axis which is perpendicular to the axis of the intake pipe, thereby making the connecting linkage short and simple, or even permitting the vane to be mounted on the pivot shaft of the throttle valve. The virtual absence of friction losses in the linkage permits the engine speed to be held closely constant by the vane throttling the fuel supply when the engine speed, and therefore the blower output increases.
