Title: Improvements in or relating to the decoration of articles made from plastics
IPC: B29C70/34
Filed: 1960-07-04
Abstract: A decorated resin-impregnated foil (that is, a thin sheet of paper or fabric impregnated with a thermosetting resin or a long fibered, well matted, cellulose with a high alpha content bound with a poly-condensation resin) is formed and, after its free ends have been joined and it has been heated to bring its resin to a similar state of condensation to that of a plastic blank of the article to be decorated, it is applied to the surface of the blank in a mould and bonded to it by means of heat and pressure which effect cross-linking between the resin of the blank and that of the foil. Where the article to be decorated is formed in a mould, the same mould may be used for bonding the foil to the article. The foil may be applied while both the article and the resin of the foil are in an incomplete state of condensation. The free ends of the foil overlap and are joined by partial cross-linking of the resin in the foil under heat or by using a resin binder. Alternatively, the free ends may have corresponding hooks and slits and be joined mechanically. The process is described with reference to the decoration of cups and ashtrays.

Title: Novel mixed alkali metal polyphosphates and methods of preparing them
IPC: C01B25/45
Filed: 1965-04-27
Abstract: Mixed polyphosphates of sodium and potassium of general formula (Na,K)x+2PxO3x+1 wherein x\sF 2 are prepared by treating calcium phosphate ore with a solution of H3PO4 and sodium or potassium sulphate, filtering off the solids containing CaSO4 and partially neutralizing the filtrate with a basic sodium and/or potassium compound, e.g. oxide hydroxide carbonate, or bicarbonate, then filtering and finally evaporating, and calcining to form the polyphosphate. The amount of sulphate added is such as to convert into CaSO4 all the calcium ions in the phosphate ore. The amount of base added is such that the ratio of sodium and potassium ions to phosphorus atoms is equal to x+ 2/x . If the H3PO4 solution is impure it can be treated with Na2SO4 and any impurity such as Na2SiF6 is removed as a separate step. Any SO4- ions present in the solution after the filtering off of the CaSO4 may be removed by adding a Ba salt as a separate step and filtering. The process may be continuous. The Na: K ratio in the product is preferably 0.3 to 0.7:1. The amount of H3PO4 added may be such that the solution has a P2O5 content of 25 to 35% weight. The K2SO4 and ore that are used in the first stage may be ground. The amount of K+ ions added in the first stage can be such that the K2O/P2O5 ratio is below 0.5 and this reaction time is 2 to 6 hours at a temperature between 35 DEG and 55 DEG C. During the neutralization the reaction time may be 1/2 to 2 hours at temperatures between 50 and 100 DEG C. The evaporation may be to a salt concentration of 48 to 55% weight when some of the calcined product can be added. Calcination may be at a temp. between 250 DEG and 500 DEG C.

Title: Current-limiting electric switch
IPC: H01H77/10
Filed: 1972-02-02
Abstract: A current-limiting electric switch is disclosed, of the kind having at least one release per pole, each release comprising two contacts carried by respective supporting members, said contacts being electrically connected to a feed and a load terminal through a current path of which said supporting members form, when the contacts are closed, two parallel branches through which currents of opposite sign flow, so that a current increase beyond a preselected limit produces in said two branches electrodynamic repulsion forces to overcome the bias of resilient supporting members and to cause the supporting members to be set apart for separating the contacts, the improvement consisting in the fact that said parallel branches are a part of a closed loop which is made up by said current path in correspondence with each release. The switch according to this invention permits to construct apparatus having shorter working times than those of the prior art and a more reliable operability.

Title: Coil wound elastomer connector
IPC: H01R12/16
Filed: 1973-01-20
Abstract: The invention concerns a method of making a connector body comprising a multiplicity of spaced resilient conductive springs disposed within a matrix of elastomeric insulating material defining a body having spaced surface parts between which the springs extend in non-rectilinear paths and at which ends of the springs are exposed. According to the method at least one wire is wound into a coil of spaced turns and the coil is potted in a mass of elastomer. The resulting body is cut through the coil turns to present the spaced surface parts. To facilitate coil formation and potting, the wire may be wound with elastomer strip or sheet spacing and the composite coil then cured to form a bond between contiguous elastomer surfaces and define a coherent matrix. Alternatively the elastomer may be injection or vacuum molded in the fluent state.

Title: Method and machine for forming random fiber webs
IPC: D04H1/72
Filed: 1975-07-05
Abstract: To form a composite random fiber web containing long and short length fibers, the two types of fibers are fed simultaneously into the same lickerin but with the shorter fibers fed into the lickerin above the longer length fibers, that is, at a point spaced angularly in the direction of rotation of the lickerin in advance of the point at which the longer fibers are fed into the lickerin. The intermingled fibers are doffed from the lickerin by centrifugal force due to the high speed rotation of the lickerin and by an air stream traveling past the lickerin, and are conveyed by the air stream to a moving foraminate condenser on which they are laid down in random fashion. In one embodiment of the invention, two lickerins are provided and two sheets of short length wood pulp fibers are fed into each lickerin angularly in advance of but simultaneously with feed of a mat of longer length textile fibers into each lickerin. A divided air stream sweeps past the two lickerins to doff the fibers therefrom.
