Title: Pourable, aqueous composition for cleaning of hard surfaces
Inventor: INSTONE TERRY
IPC: C11D3/02
Filed: 1992-07-17
Abstract: Problems of stability have bedeviled formulations of aqueous, liquid abrasive cleaning compositions comprising soluble abrasive particles. One factor which can influence the stability of aqueous compositions is the high level of electrolyte present in the compositions: ie. the soluble abrasive is typically immersed in an aqueous medium which is saturated with respect to that abrasive in solution. The electrolyte level varies with temperature and this can have detrimental effects on the product. We have now determined that these problems can be overcome by use of an essentially hydrophobic perfume composition as a stability enhancer in a pourable, aqueous, hard surface cleaning composition comprising water-soluble abrasive. Consequently, the present invention provides a pourable, aqueous, hard-surface cleaning composition comprising a water soluble abrasive, at least part of the abrasive being present as undissolved particles having a mean particle diameter of from 10 to 500 microns, further comprising and essentially hydrophobic perfume composition and a detergent, said composition remaining stable after storage at 37°C for twelve weeks or remaining stable after twelve temperature cycles from -5°C for eight hours to 25°C for sixteen hours.

Granted: 1990-04-12
Abstract: In a telecine chain, the scanning raster is rotated by applying a magnetic field perpendicular to the axis of the electron beam, and the distortion introduced by such rotation is compensated for. A rotate coil is located about the scanning tube the coil formed so that current passing through it induces the magnetic field and thus effects the rotation of the raster. The degree of rotation is within limits dependent on the current, and the direction of rotation is dependent on the direction of current flow. There is pref. an Absolute Angle Generator which has an input common with the input which controls the current through the Rotate Coil and which provides outputs for the compensation functions. Focus compensation is effected by applying a stimulus to the focus system which is based on the degree of rotation being effected.
