Abstract: 232,917. Piepmeyer & Co. Kommanditges., (Assignees of Machts, L.). April 24, 1924, [Convention date]. Electrically - tripped switches-In maintaining a level of liquid W approximately constant or for regulating other conditions a relay is used intended to have two operative end positions without a position of rest for the moving armature between such positions. With the contact 13 in its full line position the circuit for a pump is completed with the consequence that the contact 21 is gradually raised till it completes circuit at 22 for the coil 19 when the twopart armature 2, 3 is attracted and as the two parts are of iron they have a mutual attraction so that, being held apart at 11, the part 3 tips to bring the latching finger 8 out of engagement when the armature can fall to its bottom position breaking the pump circuit at 13 and the circuit of the coil 19 at 12. If the level falls, contacts 21, 23 now complete the circuit for the coil 19, the armature is again pulled up and again the pump circuit is completed at 13.

Title: Improvements in or relating to the surface treatment of films, sheets and coatings comprising organic thermoplastic materials
Inventor: BROWNING JOHN
IPC: C08J7/052
Filed: 1950-12-22
Abstract: The ability of a sheet, film, or coating, comprising an organic thermoplastic material, to slip over or to be separated from contacting surfaces is improved by applying to its surface a composition comprising a solution of a surface-active agent, which will wet but not dissolve the surface, having dispersed therein a finely divided synthetic organic polymerization product that is not harder than the surface, and drying the film, &c. under conditions such that the synthetic organic polymerization product remains on the surface in the form of discrete particles. The solvent for the surface-active agent may be water.  The polymerization product may have a particle size of 0.1 to 20 microns.  It may be a polythene, polytetrafluoroethylene, poly (trifluoro-mono-chloro-ethylene), an interpolymer of ethylene with another polymerizable substance, polyvinyl chloride, polyvinyl acetate or a superpolyamide.  The film, sheet, or coating may be formed from the same or a harder polymeric substance.  The composition may contain an emulsified wax to improve the adhesion of the particles of polymerization product to the treated surface. p  Microcrystalline petroleum wax, beeswax, paraffin wax, and waxy polyethylenes and polyisobutylenes are specified.  For the treatment of polythene and polyethylene terephthalate films, the surface-active agent used in the composition which is applied may be a water soluble alkyl aryl polyglycol ether such as is produced by reacting ethylene oxide with dibutyl, diamyl, cyclohexyl, octyl, isooctyl, dodecyl or di-tertiary hexyl phenol, or di-tertiary butyl cresol.  Other surface-active agents specified are sodium lauryl sulphate, sodium cetyl sulphate and condensation products of ethylene oxide with long chain fatty acids such as cetyl alcohol.  The treatment also reduces the tendency of the thermoplastic film or coating to accumulate static electricity. If desired a mixture of two surface-active compounds may be included in the composition, one for its dispersing properties and the other for its anti-static properties.  The composition may contain 0.25-10 per cent. by weight of surface-active compound and 0.1-5 per cent. of the polymerization product.  In examples, polythene and polyethylene terephthalate films are passed through water baths containing a dispersion of polythene or polytetrafluoroethylene with triethanolamine stearate and a condensation product of ethylene oxide and isooctyl phenol. Specification 681,517, [Group VIII], is referred to.
