Title: A Method of Manufacturing Multiple Glazing Units
Inventor: GOTO EIZO
IPC: E06B3/673
Filed: 1967-10-05
Abstract: 1,156,250. Multiple-glazing units. TOKYO SHIBAURA ELECTRIC CO. Ltd. 5 Oct., 1967 [8 Oct., 1966], No. 45517/67. Heading ClM. A multiple-glazing unit is made by vertically supporting two or more glass sheets in a predetermined spaced relationship, with spacing means positioned around the edges and between each adjacent pair of sheets and successively dipping each portion of the edge of the supported unit in a bath of molten glass to form a continuous hermatic seal around the complete periphery of the unit. In the embodiments described two or three sheets of glass 7 are sealed together leaving a space 10 between each adjacent pair of sheets. The size of the space is determined by spacing members 8, which may be of metal, glass or a ceramic material and have a U-shaped cross-section (Fig. 2a, not shown), an H-cross-section (Fig. 2b, not shown), or a solid rectangular crosssection (Fig. 2e, not shown). The unsealed unit is vertically supported between suction clamps 9 and the edges of the unit successively immersed in a bath of molten glass 2 to form the seal. Where a particular atmosphere (e.g. dry air, nitrogen or argon heated to 530‹ C. at a pressure of 1700 mm. Hg.) is desired to be sealed within the enclosed spaces of the unit the sealing is carried out within the desired atmosphere. The bath of molten glass is heated electrically, using electrodes 3, 4. It is advantageous that the spacer, e.g. 108 (Fig. 3) be electrically heated to assist sealing. The lead to the spacer is cut off after sealing. It is preferred that the coefficient of expansion of the glass sheets, the spacers and the glass forming the molten bath be all the same. To obtain a good seal the glass sheets are preheated to at least 400‹ C.

Abstract: 1452110 Shutter timing circuits ASAHI KOGAKU KOGYO KK 5 Oct 1973 [6 Oct 1972 (2) 23 Oct 1972 (2)] 46698/73 Heading G2A In a shutter control circuit, pulses are generated at a frequency varying according to the intensity of the object light, one pulse controlling shutter opening and the or a succeeding pulse, selected according to an exposure factor setting, controlling shutter closing.  In Fig. 2, a UJT 10 is connected to a photoconductor 7 and capacitor 9 to generate pulses. A first pulse fires a thyristor 14 which energizes an electromagnet 16 to open the shutter and close a switch 22. Closure of switch 22 initiates charging of a capacitor 21 connected to a photo-conductor 8 and an ASA setting resistor 19. A UJT 23 discharges capacitor 21 at a predetermined voltage to fire a thyristor 26 and this biases a diode 28 so that the next pulse from the UJT 10 can fire a thyristor 29 and energize a shutter closing electromagnet 31. Figs. 4, 6 and 7 (not shown) show modifications of Fig. 2 including memory and logarithmic circuits. In Fig. 8 pulses from a UJT 209 are fed to flipflops 218a ... 218m, two pulses turning on 218a, four turning on 218b, eight turning on 218c &c. A switch 219 connects one of the flip-flops (selected according to ASA) to a thyristor 223 which, upon being fired by the turning-on of the selected flipflop, biases a diode 222 such that the next pulse from UJT 209 fires a thyristor 226 to close the  shutter. In Fig. 11 pulses from a UJT 310 are stored in a capacitor 328, the resulting emitter voltage of a transistor 325 is divided by an exposure factor setting resistor 329 and is applied to a diode 330. When this voltage reaches a sufficient value, the next pulse from the UJT turns diode 330 on, and fires a thyristor 331 to close the shutter. Figs. 14, 15 (not shown) show modifications including memory and logarithmic circuit. Figs. 16, 17 and 21 (not shown) show a feedback circuit for capacitor 328 to make the timing of longer exposures more accurate.

Abstract: 1,192,208. Coating. ANCHOR POST PRODUCTS, Inc. 13 Oct., 1967 [2 Dec., 1966], No. 46876/67. Heading B2K. [[Also in Division D1] Metal articles e.g. wire are coated by continuously applying a pulverulent, flowing material in an unaerated compacted condition to the surface of the moving article and fusing the pulverulent material. Fig. 1B is a downward continuative of Fig. 1A. A wire W which has been cleaned of scale and grease by solvents pickling, or grit blasting is passed through a primer coating chamber 14 through which primer is passed by a pump 26. The primer is dried and cured in a tube 10 through which air from a blower 28 passes. The tube is heated by an induction coil 16 or by radiant, convertion or resistance heating. The wire then passes to a coating section 40 comprising a hopper 42 and an H-shaped coatercirculator 44. The arm 43 of the circulator 44 depends from the lowermost end of the hopper 42. The arm 45 of the circulator 44 extends to near the top of the hopper 42. Coating powder is introduced from time to time to hopper 42 through its cover 41. Recirculation of the powder is accomplished by air introduced at valved inlet 60 from blower 28. Another valved inlet 66 extends coaxially upward into the arm 45. A small portion of air is provided at an inlet 55 to prevent powder from entering the seal 52. From the arm 45 the powder and the air mixture enters the hopper 42 where separation takes place, the air escaping through an opening 72 and the powder filling the arm 43. The powder is compacted therein by electrically operated vibrators 100. Heat is removed from the coated wire by a long vertical travel. Steel wire may be coated with vinyl thermo plastic resin using a primer of thermosetting material in solvent and containing metal pigments higher in the electro motive series than iron. Steel wire may be coated with polyolefin thermoplastic such as polyethylene or polypropylene containing metal in flake or powdered form, metal oxide, hydroxides, metal carboxyl groups and including heat and ultra-violet stabilizers as well as pigments. The primer is a weak acid solution of a base metal higher in the electromotive series than iron. In the coating of steel wire with thermosetting material such as epoxy-polyamide containing pigments and stabilizers, the primer is a phosphate treatment. The articles to be coated may be any metal strip or web, filaments in other forms than wire such as flat coil, and tubing. The powder may also be maintained in a circulating condition by the use of a vacuum lift, mechanical life such as a screw conveyer or similar powder lifting device.
