Title: Thermal relay with a heated bimetal element and a temperature compensating bimetal strip
IPC: H01H61/02
Filed: 1967-03-03
Abstract: and G1D. A snap-action thermal switch with ambient temerature compensation comprises a coil-heated bimetallic element 8 Fig. 2 and a compensating bimetallic element 9 fiexd at one end in parallel relationship to a common pivotal mounting 5. The opposite end of the heated element 8 is adjustably fixed by engagement over a set screw 21 while the free end of the compensating element 9 is coupled to spring contact 14, 15 through a pivotal link 23 whereby the contact 15 is moved with snap-action between fixed contacts 16, 17. In modifications the heating current may pass through the bimetal element 8 to one end of the heating coil 11. In a further modification the heating coil 11 is protected from over-heating by a thermal cut-out switch in the heating circuit comprising a spring contact attached to the pivotal mounting 5 adapted to move away from a fixed contact on over-heating. In one example a photo-conductive cell 31 Fig. 13 in circuit with the heating coil 11 is used in switching street lights under control of daylight conditions. During daylight the resistance of the cell 31 is low and currents flows through the heating coil 11 and holds the switch 14, 17 in the lamp circuit in the "off" position.

Title: Packaging consisting of thermoplastic foil
IPC: B26F1/24
Filed: 1967-03-22
Abstract: A tear line 40 for separating into a number of parts, a packaging or box of thermoplastic foil comprises a region along whose length the molecules are orientated in the direction of separation. It is formed by clamping the heated foil at both sides of the tear line region so that drawing of the foil for making the remainder of the packaging does not interfere with orientating of the foil molecules along the tear line. As described, the packaging, for e.g. eggs or fruit, comprises similar halves 1, 2 integrally joined by a web 3 and having depressions 20 which facilitate nesting and have ribs 25 to support resiliently the contents. Press studs A, B, see, also Figs. 6, 7 (not shown), secure the packaging closure. The packaging is vacuum or compressed air-formed in reciprocable male and female dies C, D. The tear line 40 is formed in the foil 62 by a row of needles 64 and clamped at each side during formation by a resiliently loaded rail 66. To prevent the walls of the web formed between the points 41 from welding together, the needles are arranged alternately short (6411) and long (641), Fig. 5 (not shown).

Patent ES-353194-A1 (ES)
Title: Coating method for strengthening vitreous and vitrocrystalline bodies
IPC: C03C17/02
Filed: 1968-04-26
Abstract: A layer of vitreous or vitro-crystalline material is strengthened by covering the layer while in the solid state either entirely or at zones which are laterally opposed with respect to a mid-surface of the layer with a solid coating(s) in which compressive stresses can be produced or increased by chemically modifying the coating in heated condition while the coating(s) remain solid, with the aid of a reactant in contact therewith and then cooling the coating(s). The coating(s) are preferably from 1 to 150 microns thick and the layer may be less than 3 mm. thick. The chemical modification may involve the combination of an element or compound in the coating(s) preferably of invariable valency e.g. Sn, Ti, Si, V, Pb, Mn, Al, Zr, Th, Bi, Ni, or SiO, TiO, SnO, PbO with another substance e.g. oxidation with ozone or molten KNO 3 , or combination with S, Te, Se or another element the ions of which have a greater ionic radius than oxygen. The chemical modification may involve an ion-exchange e.g. of alkali metal ions between the coating(s) and a contacting medium e.g. the replacement of Na+ in the glass coating(s) by K+ at a temperature below the annealing point of the glass, or the replacement of Na+ in the glass by Li+ at a temperature above the annealing point and confers a lower coefficient of thermal expansion on the glass coating. In the examples (i) a titanium film was deposited by vacuum evaporation on both surfaces of a soda lime glass disc and the film was oxidized with ozone at 550 C. (ii) a SnO film was deposited on the internal and external surfaces of a soda lime glass beaker from an alkaline solution of stannous chloride, and the film was oxidized with molten KNO 3 at 500 C. (iii) a sheet of partially devitrified glass composed by weight of Li 2 O 15%, Al 2 O 3 10%, SiO 2 , 50%, CaO 10%, B 2 O 3 , 8%, TiO 2 7% was coated on both faces with an 80: 20 mixture of germanium and sodium by vacuum deposition. The coated sheet was then exposed to H 2 S and the germanium was sulphurized by the sodium polysulphides formed. The resultant coating(s) are vitreous and pale red and are a mixture of GeS 2 and Na 2 S (iv) vitreous layers of GeS 2 , CdS, Na 2 S formed by sulphurizing the respective metal on both surfaces of a sodalime glass sheet were immersed in a bath of KCl and NaCl and resulted in a substitution of Na+ by K+ in the vitreous coatings and surface layers of the glass sheet (v) an enamel comprising the following molecular proportions SiO 2 40, B 2 O 3 10, PbO 25, PbF 2 5, NaF 10, ZrO 2 3, CdO 7 and containing 2% by weight zinc powder was deposited on both faces of the devitrified glass of the composition above and was exposed to dry hydrogen selenide gas at 400 C. The zinc in the coating reacted to form ZnSe which was in the vitreous state.

Filed: 1968-06-21
Abstract: The exhaust gases from an oxygen blown converter are passed from a hood 19 through a cleaning apparatus 27, 29 to a stack 35 or storage by an induced draught fan running at a constant speed to pass a constant volume of gas equal to the maximum volume of gas evolved at the converter plus a volume of air sufficient to oxidize at least 20% of the maximum volume of CO evolved. A damper 40 enables this rate to be adjusted. Inert gas or steam is injected into the hood 19 near the inlets 39, 22, Fig. 3, for an oxygen lance 17 and an additive shoot 21 to prevent egress of waste gases. A skirt 47, Fig. 3, mounted on wheels running on a track 57 may be moved into the gap between the hood and the converter outlet.
