Title: Coating articles
IPC: B05D1/18
Filed: 1974-07-15
Abstract: 1475595 Coated articles; heating and cooling coating solution OMNITECH Inc 15 July 1974 [10 Sept 1973] 31262/74 Headings B2E and B2L A method of applying a scratch resistant coating to articles, e.g. lenses and visors, includes the steps of maintaining a supply of coating solution in a reservoir, e.g. a composition of polysilicic acid and a copolymer of chlorotrifluoroethylene or tetrafluoroethylene and a vinyl ether, circulating the solution to a coating station where the articles are coated and back to the reservoir, the temperature at the coating station having sufficiently above room temperature to precure the coating and the solution in the reservoir being continuously cooled below room temperature, Cable 52 is driven intermittently to carry articles on workholders 96 from loading station 20 to cleaning station 102 where the articles are cleaned by ultrasonic cleaner 104. The articles are then moved to destaticising station 116 where they are destaticised by blower 118. After destaticising, the articles are moved to coating station 122 and coating tank 124 is raised by a piston and cylinder assembly 128, 130 so as to immerse articles 98 in the coating solution. The tank is then lowered at a controlled rate so as to obtain a coating of the desired thickness. Coating solution is supplied to tank 124 from reservoir 142 through filter 144 by means of pump 138. Overflow trough 150 carries overflow to return line 152 and thence to reservoir 142. The atmosphere at the coating station is maintained at about 90F and the solution in reservoir 142 is maintained between 40F and 50F by means of refrigerating block 160. Light is directed from lamp 182 mounted above the upper edge of trough 150 towards a photoresponsive device 184. The light path is interrupted so long as the tank is raised to a level at which articles are partially immersed therein. When the light path is no longer interrupted, device 184 energises a winding which opens a valve to exhaust cylinder 128 and permit tank 124 to return to its initial position.

Title: Radiation sensitive transducer
IPC: H01L27/14
Filed: 1975-07-29
Abstract: 1486509 Radiation detectors INTERNATIONAL BUSINESS MACHINES CORP 29 July 1975 [23 Aug 1974] 31637/75 Heading G1A A radiation-sensitive transducer comprises: a plurality of strain-sensitive resistive elements each connected to a respective radiation-sensitive switch coupled to an electric source; means for propagating strain pulses through successive elements to change their resistances; and means for detecting changes in current passing through those elements which undergo a resistance change while their respective switches are selectively closed by incident radiation. Parallel strain-sensitive resistive stripes 20, deposited on a substrate 25 of low acoustic loss, e.g. fused quartz or glass, are each connected at one end to a respective conductive pad 22 separated from a transparent electrode 32 by a photo-conductive layer 24, and at the other end to a common conductor 28. An acoustic transducer 27 mounted on the substrate 25 is arranged to propagate a surface wave or bulk wave transversely of the stripes 20, causing each stripe in turn to undergo a resistance change. In the equivalent circuit of Fig. 3, RMR represents a stripe resistance, Cp the capacitance of a local region of the photo-conductor 24, and Rp its resistance which varies, in relation to RMR, from a high value in darkness to a low value when illuminated. A D.C. voltage source 26 is connected to the transparent electrode 32, and a detector 30, having an input impedance R O , to the common conductor 28. As the transducer is scanned by the acoustic wave (e.g. in a document reader), any stripe carrying substantial current due to illumination of a local photo-conductor region will cause a change in that current as R MR changes, so applying a voltage pulse to the detector 30. In an alternative embodiment Figs. 4-6, (not shown) the substrate (25) is backed by a dielectric layer (44) covered by a ground plane (42), the D.C. voltage source being replaced by an A.C. source (40) connected between the transparent electrode (32) and the ground plane (42). The strain-sensitive resistive elements may be constituted by a magnetoresistive material which is also magnetostrictive.

Abstract: The invention comprises compounds of formula R1-O-CR2R3-CHR4-SO2-O-R5 which contain at least nine carbon atoms, where R1 is a C1-C20 alkyl group, a C3-C20 alkenyl group, a cycloalkyl group with 5 to 12 carbon atoms in the ring, a C2-C12 hydroxy alkyl group, a C3-C12 alkoxyalkyl group, a C4-C23 dialkylaminoalkyl group or an alkylarylaminoalkyl group with up to 23 carbon atoms; R2-R4 are hydrogen atoms or C1-C3 alkyl groups; R5 is a C1-C18 alkyl group, a C6-C15 aryl group, a C7-C13 alkoxyaryl group, a C6-C12 halogenaryl group or a C7 thiocyanoaryl group.  The invention also includes a process for making compounds of the above formula, without the restriction to 9 upon the total number of carbon atoms in their molecules, by treating the corresponding vinyl sulphonic acid ester with an excess of alcohol in the presence of 0.02-0.1 equivalent per mol. of ester of an alkali or alkaline earth metal alcoholate, a dry alkali hydroxide or a quaternary ammonium base of the formula [R1R11NR111R1111]+ OH-wherein R1, R11 and R111 are C1-C3 alkyl groups and R1111 is a C6-C10 aryl group, a C7-C9 aralkyl group or a cycloalkyl group having 5 to 12 carbon atoms in the ring.  Inert solvents may be present. The temperature may be in the range -10 to 100 DEG C. but preferably the reactants are mixed at a lower temperature and slowly heated. The alcohol may be present in 1.3 times the stoichiometrical amount but is generally used in considerable excess, e.g. 2 to 8 times the stoichiometrical amount.  The esters may be hydrolysed to form the free acids or salts thereof which have surface-active properties when R1 has at least 6 carbon atoms.  Preferred starting esters are derived from vinylsulphonic acid, a -methylvinylsulphonic acid and 1-propene sulphonic acid and from phenols and naphthols which may contain one to three inert groups such as alkyl, alkoxy, halogen and thiocyanate groups.  Typical of specified alcohols are propanol, 2-ethylhexanol, allyl alcohol, palmityl alcohol, butane-1,4-diol, dodecane-1, 12-diol, glycol monomethyl ether, triglycol, methylstearylaminoethanol, cyclopentanol, cyclooctanol, benzyl alcohol and phenylmethyl carbinol.  Esters containing aryl residues in the ester group and 4-20 carbon atoms in the ether group are plasticisers for polyvinyl chloride.  Examples given include the preparation of b -allyloxy-ethane sulphonic acid cresyl ester, b -nonyloxy-ethanesulphonic acid methyl ester, b (NN-dimethyl-2-aminoethoxy)-ethane sulphonic acid cresyl ester, b -cyclohexyloxyethanesulphonic acid-a -naphthyl ester, b -allyloxy-ethanesulphonic acid-2-chlorophenyl ester, and also the use of vinylsulphonic acid o-bromophenyl ester, vinylsulphonic acid p-iodophenyl ester, vinylsulphonic acid p-fluorophenyl ester and vinylsulphonic acid p-thiocyanophenyl ester.
