Title: A method of producing a resinous composition containing glycidyl ethers and suitable for use as an adhesive, the resinous composition so produced and articles made therefrom
IPC: C09J163/02
Filed: 1949-07-22
Abstract: Cold hardening resinous compositions suitable for use as adhesives comprise a glycidyl ether having an epoxy equivalent greater than one obtained by condensation of 1 mol. of a dihydric phenol and 1-2.5 mols. epichlorhydrin in presence of at least an equivalent quantity of alkali, a non-volatile solvent, and 5-25 per cent triethylamine as curing agent, the quantity of solvent being such as to give the mixture an initial viscosity of 500-100,000 centipoises at 20 DEG  C. The solvent may be inert, e.g. dibutyl phthalate or tricresyl phosphate, or reactive with the condensate, e.g. liquid compounds containing a 1,2-epoxy group such as styrene oxide, butadiene monoxide, phenyl glycidyl ether or glycidyl ethers of polyhydric alcohols.  A reactive solvent which is particularly suitable is the condensation product of glycerol with epichlorhydrin obtained by reaction of one mol. epichlorhydrin for each molar equivalent of hydroxyl groups in the polyhydric alcohol in presence of boron trifluoride or hydrofluoric acid as catalyst and dehydrochlorinating the product in presence of sodium aluminate.  Dihydric phenols specified are resorcinol, catechol, hydroquinone, bis-(4-hydroxyphenyl)-2,2-propane, 4,41 - dihydroxy - benzophenone, 1,5 - dihydroxy-naphthalene.  In an example a resin "A" is obtained by condensing 4 mols. of bisphenol and 5 mols. epichlorhydrin in presence of 6.43 mols. of NaOH present as a 10 per cent aqueous solution, the reaction mixture being heated to 100 DEG  C. in 80 minutes and refluxed at 100 DEG  C. for a further 60 minutes.  The aqueous layer is then decanted and the resin washed until neutral. This resin " A " is then dissolved in ether " B " obtained by reacting 3 mols. glycerol and 9 mols. epichlorhydrin in a diethyl ether solution containing 4.5 per cent boron trifluoride, the temperature being maintained at 50-75 DEG  C. and the product obtained being dehydrochlorinated by heating in dioxane containing sodium aluminate.  Tables are given in the Specification of the pot life and shear strength of laminates made from phenolic layers united by adhesives comprising equal parts of resin A and ether B and containing 5, 10 and 15 per cent of triethylamine.  Comparison is made with similar adhesives made up in like proportions but containing diethylamine, triethanolamine, di-n-propylamine, di-isopropylamine, methyl di-isopropylamine instead of triethylamine. Tables are also given showing the shear strengths of various metals united by the composition and of the effect of adding phenyl glycidyl ether to solvent B.  The compositions may also be used for manufacturing shoes from leather, rubber and plastic sheeting; for joining glass; for making laminate furniture.  The adhesive can be mixed with various fillers, e.g. clay, wood, flour, cotton lint, fibres and pigments.  Specification 630,663 is referred to.

Title: Apparatus for measuring the heat-insulating capacity of textile fabrics and the like
IPC: G01N27/18
Filed: 1948-07-22
Abstract: 654,534. Determining heat - coefficients. GIANDOMENICI, U. July 22, 1948, No. 19659. Convention date, May 30, 1942. [Class 97 (iii)] In order to measure the heat insulating capacity of textile fabrics or any other sheet material, a chamber 2, completely enclosed on all sides, is formed of the material on a framework 1, and contains adjustable sources of heat, e.g. electrical resistances 3 and the bulb of a thermometer 4. The heat supplied by the sources 3 is adjusted until the temperature inside the chamber remains constant and the heat-insulating capacity of the fabric is then calculated from the amount of energy consumed in maintaining a desired internal temperature constant. The heat supplied to the chamber may be varied to attain the desired constant temperature by means of a resistance 17 in the supply leads to the heaters 3, the energy consumed being proportional to the square of the voltage as indicated by a voltmeter 18 or, by means of a change-over switch 37, the temperature inside the chamber may be maintained constant by means of a thermostat comprising an electric resistance thermometer 26 controlling a relay 28, in the latter case a wattmeter 29 being included in the circuit to measure the power consumed. The bulb of the thermometer 4 inside the chamber is protected from the direct action of the heaters 3 by asbestos screens 9 and the air inside the chamber is circulated by means of a fan 23. The experiment may be conducted under varying external conditions, humidity and temperature of the surrounding atmosphere being variable by a fan 5 and a water spray 6, a hygrometer 21 and thermometer 22 being supplied for external measurements.

Title: Totalizing counter mechanism for a maximum demand meter
IPC: G01R11/60
Filed: 1953-07-16
Abstract: 737,524. Counting-apparatus. LANDIS & GYR AKT.-GES. July 16, 1953 [July 26, 1952], No. 19801/53. Class 106 (1). In a maximum-demand electricity or other meter having means for periodically resetting the maximum-demand indicator 11 and transmitting the settings cumulatively to a countnig mechanism 23, exact unit registration by the counting mechanism, corresponding to the graduations of the maximum-demand scale, is ensured by means of a toothed regulating wheel 71 controlled by an escapement pallet 72 in the transmission to the counting mechanism. The resetting and transmission mechanism is otherwise substantially as described in Specification 737,523 and comprises a toothed wheel 20 geared to the indicator 11 and bearing a stud 22 which moves away from a fixed stop 59 as the indicator advances. The wheel 20 gears with a pinion 26 normally freely revoluble on the shaft of a friction coupling 30, 31, which shaft is connected to the units wheel of the counting mechanism 23. When a handle 38 is turned to effect resetting, the coupling 30, 31 is engaged and the stud 22 driven back against the stop 59, so returning the indicator and correspondingly advancing the counter. This resetting action is effected by one revolution counterclockwise, Fig. 3, of a cam disc 50 bearing a back drive pawl 52 for the stud 22. A follower arm 61 for the cam profile of the disc is secured to a shaft 60 which also bears an arm 62 for engaging the coupling 30, 31 and is adapted to actuate the pallet 72 through a spring 73. Normally a rise 50a of the cam engages the arm 61 causing the pallet tooth 72a to engage the wheel 71. Immediately the cam rotates, the arm 61 moves inwardly to disengage the tooth 72a so that the wheel 71 is free to rotate. When resetting is complete, the rise 50a re-engagea the arm 61 to re-engage the tooth 72a with the wheel, the tooth camming the wheel into an exact unit registration position of the counter 23 and a lost-motion connection between the wheel 20 and stud 22 allowing slight further movement of the wheel 20 when the stud has reached the stop 59. A depression 50b in the cam disc causes the second tooth 72b of the pallet to engage the wheel momentarily immediately before the tooth 72a is engaged, in order to prevent the tooth 72a engaging a tooth point of the wheel. The teeth of the wheel 71 have asymmetrically sloping faces to take up tooth play between the gears 27, 28 and 20, 26.
