Title: Improved heat resistant insulating materials
IPC: C08L83/04
Filed: 1945-09-25
Abstract: A composition from which heat resistant insulating coatings or films are obtained comprises a cellulose ether and an organo-silicon oxide condensation product consisting essentially of structural units having the formula R-Si-O1.5 in which R is a monovalent hydrocarbon radical, in a common organic solvent.  After application to a surface, the solvent is evaporated to produce coatings or films and the solvent-free product is then subjected to heat to convert it into a nonsoftening condition.  Specified cellulose ethers are ethyl, propyl, butyl, benzyl and ethylbenzyl cellulose.  The organo-silicon oxide condensation products are obtained by hydrolysing R-Si-X3 in which X = halogen and/or alkoxyl. The monovalent hydrocarbon radical R may be methyl, ethyl, propyl, isopropyl, butyl, isobutyl, amyl, hexyl, heptyl to octadecyl; alicyclic radicals such as cyclopentyl, cyclohexyl; aryl and alkaryl such as phenyl, mono- and poly-alkyl phenyls, e.g. tolyl, xylyl, mesityl, mono-, di-and tri-ethyl phenyls, and mono-, di- and tri-propyl phenyls; naphthyls; mono- and poly-alkyl naphthyls such as methyl naphthyl, diethyl naphthyl and tripropyl naphthyl; tetrahydronaphthyl; anthracyl; aralkyl such as benzyl or phenylethyl; alkenyl such as methallyl or allyl.  Colouring matter, pigments, fillers and finelydivided dielectric solids may also be added to the composition.  In examples, compositions containing the condensation product obtained by hydrolysing methyl triethoxy silane or ethyl trichlorsilane are mixed with ethyl cellulose in toluene-isopropanol or toluene-ethanol, and in some cases pigments, e.g. aluminium powder, ochre, red lead and ultramarine are added.  The solutions are applied to a surface, the solvent evaporated and the resulting coating or film heated.

Title: Strip length gauge and control
IPC: G01B21/06
Filed: 1966-06-03
Abstract: 1,146,192. Measuring strip length electrically. UNITED STATES STEEL CORP. June 3, 1966 [June 11, 1965], No.24930/66. Heading G1N. Apparatus for measuring the length of moving strip stored in a looping pit 2 comprises two D. C. tachogenerators 16, 18, which generate respective D. C. voltages proportional to the speed of the strip entering the pit and the speed of the strip leaving the pit, and two integrators (26, 28), Fig.2- 2a (not shown), which can be selectively connected to the outputs of the generators, as described below, to allow a continuous reading of the stored length even during a recalibration cycle. In order to measure the stored length, the difference in the generated signals is integrated by one of the integrators, say (28), the output of which is fed to a measuring circuit (30) comprising a self balancing resistance circuit having a meter (32) calibrated to indicate the stored length. When a new length of strip is welded on by a welder 6, a hole is punched in the strip by a punch 8 which initiates a recalibration cycle. During the recalibration cycle, the signal from generator 16 is automatically connected to both integrators while the signal from generator 18 is connected to integrator (28) only. When the hole is detected leaving the pit by an optical hole detector 20, the output of integrator (26), which is proportional to the stored length of strip, is automatically connected to the measuring circuit, generator 18 is connected to integrator (26), and integrator (28) is reset, thereby completing the recalibration cycle. The difference in the generated signals is now integrated by integrator (26) so that meter (32) can follow variations in the stored length. During the\next recalibration cycle, the roles of integrators (26), (28) would be interchanged. If when the hole is detected the outputs of the integrators differ by more than a predetermined amount appropriate action is taken automatically. Thus, if the output of integrator (26) is too far below that of integrator (28), due e.g. to the detection of a hole other than the recalibration hole, a relay (66) operates whereby the detected hole is ignored. If the output of integrator (26) exceeds that of integrator (28) by more than a predetermined amount, e. g. because the recalibration hole has been missed, the relay (66) operates in the opposite direction whereby a new recalibration cycle is automatically started the next time a hole is punched. If the stored length drops below a first predetermined value, a hooter is energized and if the stored length drops below a second, lower, predetermined value, the line is automatically stopped. If the line is stopped for more than, say, 5 minutes, a timer relay (60) operates to hold the working integrator from drifting and, if the stoppage occurred during a recalibration cycle, to initiate automatically a new recalibration cycle when the next hole is punched after restarting. Potentiometers (88, 90) are adjustable to take account of variations in roller diameters.

Abstract: 862,254. Selective printing. OLYMPIA WERKE A.G. Aug. 9, 1957 [Aug. 16, 1956], No. 25184/57. Class 100(4) In a printing machine for recording the output of calculating machines and which comprises a line of printing members forming characters by the selective operation of a number of separate printing elements, electronic means are provided so that a progressive letter-by-letter connection of the outputs of a distributor Vr is made from the elements of one printing member to the elements of the next. The output of the calculating machine is connected to the terminals 0-9, +, on the distributor Vr. Diode interconnections A, B-X are provided to selectively energise the lines a-z<SP>1</SP> which correspond to elements a-z<SP>1</SP> of each printing member Fig. 2. These lines however do not go direct to each printing member but to a network comprising a number of "and" gates, A 1 -A 20 , B 1 -B 20  &c. for a twenty column printer. The second input to each "and" gate is derived from a ring counter Rz consisting of individual flip-flops I to XX energised successively, and only if both inputs are present on one "and" gate, are the output lines a 1 -y<SP>1</SP> 1  energised to operate the selected elements in that column. Thus, if say flip flop II is energised, all the "and" gates in the series A 2 , B 2  &c. which have received signals from the distributor Vr operate an element a-z<SP>1</SP> of a printing head. Specification 845,717 is referred to.

Title: The manufacture of alpha naphthyl acetic acid
IPC: C07C51/347
Filed: 1948-09-28
Abstract: a -Naphthylacetic acid is manufactured by heating monochloroacetic acid or the anhydride or an ester thereof with naphthalene in the presence of a metallic chloride catalyst, preferably ferric chloride or a body capable of liberating ferric chloride under the reaction conditions.  The reactants may be refluxed until the calculated amount of hydrochloric acid is liberated from the reaction mixture. Elevated pressure and higher temperature enable the duration of the reaction to be reduced or the vaporous reaction mixture may be passed over the catalyst. The catalyst may be supported on silica gel, active carbon, pumice stone or similar carriers and should be finely powdered when operating in solution or crushed in vapour phase operation. a -Naphthylacetic acid is obtained from the reaction product by extraction of the solution obtained, tarry impurities being precipitated by suitable adjustment of the pH before the a -naphthyl acetic acid.  In an example monochloroacetic acid, naphthalene and anhydrous ferric chloride are refluxed.  The reaction products are extracted with dilute caustic soda solution and the resulting solution is acidified in two stages with hydrochloric acid, the second precipitate being the desired product.
