Title: Crank arm drive for shaft - has cam drive for connecting cables allowing low starting loads
IPC: B62M1/24
Filed: 1974-03-20
Abstract: The force required to initiate the rotation is small. This is achieved by connecting a cam (2) to each crank (1) rotating about an axis (3). The radius of the cam is small near the crank arm but increases with angular displacement to a maximum, at which it may stay consistant or reduce somewhat. A drive line (4) is attached to the crank, passes over the cam profile and is then connected to a free wheeling sprocket (7) on the shaft (9) via a length of chain is attached to a return spring (6). Repeated actuation of the crank thus rotates the shaft. Several cranks may be used to drive one shaft.

Title: Controller for flocculation of particles in liq. - with optical system giving optimum flocculant dosage and automatic determn.
IPC: G01N15/06
Filed: 1974-04-08
Abstract: A method of controlling flocculation of particles suspended in a liq., which consists of measuring the diffraction of a pencil of rays by the particles, incorporates circulating the mixt. of liq. and flocculant through a retarding stage to introduce a delay, agitating the mixt. and passing it through a cell placed in a beam of monochromatic light from a convergent optical system. The beam falls on to a photosensitive device which gives a signal X1 representative of the luminous flux diffracted by the cell contents between two directions at angles .025 lambda and .065 lambda radians to the centre ray (lambda = wave-length, microns). S1 increases with increasing flocculant rate passing through a max. The signal is plotted against flocculant rate and the max. observed. Alternatively it can be sent to an electronic circuit and used to control the pump motor at the optimum rate. System is used in water treatment where colloidal particles which escape decantation and filtration are agglomerated by a flocculating agent.
