Title: Web handling mechanism
IPC: G03B1/56
Filed: 1972-04-27
Abstract: 1379687 Cinematography EASTMAN KODAK CO 27 April 1972 [3 May 1971] 19694/72 Heading G2E In web handing apparatus, e.g. a cine projection, an interlocking arrangement is provided which automatically switches a film advance mechanism from its "still" to "run" mode when a film stripping mechanism is activated. As shown in Figs. 2, 4 an arm 286 is pivoted about pin 296 and carries a follower 284 engaging cam 275. The cam 275  produces the intermittent film advance movement by means of followers 278 (movement parallel to film), 284 (film engaging movement). Movement of the arm 286 between the "run" mode position, see Fig. 4, and the "still" mode position, (solid  lines) in Fig. 2 moves the follower 284 between an undulating and a flat track respectively on an endface of the cam 275. This movement can be achieved manually by use of the handle 287 on the arm 288 pivoted at 290 or by means of arm 246, which is depressed by the lowering of arm 245 when the film stripping mechanism is activated. The latter can occur regardless of the setting of the handle 287. To prevent overheating of the film in the "still" mode a heat resistant screen 308 is placed in the optical path.

Title: Methods of forming a solderable gold film on a glass or ceramic substrate
IPC: H01R12/57
Filed: 1962-05-24
Abstract: A solderable gold film, to which an element is subsequently soldered, is formed on a glass or ceramic substrate by applying to the substrate a gold-containing composition which can be decomposed by heat into elemental gold and organic materials, and firing the coated substrate at a temperature between 150 DEG F. and 350 DEG F. below the softening point of said glass or ceramic material and for aperiod of time of from 1/2 hour to 3 hours. Suitable gold-containing compositions are those used for providing decorative fired-on metallic gold films.  Similarly, suitable solvents, fluxes and viscofying agents that may be included in the composition are those used in the gold decorating art.  Suitable substrates include lime, flint and heat-resisting glasses.  Leads are soldered to the gold film using solders and soldering fluxes normally used for soldering prepared leads to metallic gold.

Title: Process and apparatus for annealing steel strip
Inventor: LOGAN JOHN EMERSON
IPC: C21D9/52
Filed: 1966-05-06
Abstract: 1,142,336. Annealing and cleaning steel strip. G.W. JERNSTEDT. May 6, 1966, No.20204/66. Headings C7A, C7E and C7N. Carbon or alloy steel strip or wire is continuously annealed by heating it rapidly (e.g. in 1-5 seconds) to an annealing temperature in the range 1300‹-1400‹F., holding it at that temperature for 0À5-3 seconds, cooling it in 0À5-5 seconds to a temperature in the range 1050‹ -1150‹ F., reheating it rapidly to the annealing temperature, and finally cooling it rapidly to below 300‹ F . The intermediate cooling and reheating may be repeated one or more times, whilst vibratory energy may be applied to the strip during the annealing. Heating and cooling are preferably carried out by baths of liquid metal such as lead, bismuth, sodium, lithium, or sodium-potassium mixtures, reactive metals such as sodium additionally effecting the removal of surface films of gas and oxide from the strip and producing a bright surface on the latter. As shown in Fig.1 strip 1 passes continuously into chamber 3 which is subdivided by partitions 8, 9 and 10 and which contains molten metal. During its passage through zone 4 the strip is rapidly heated to the annealing temperature under the influence of heating elements 20, 21, 22, and 23, and it then traverses the zone 5 where its temperature is maintained by elements 28. It next passes to zone 6, where it is cooled to the intermediate temperature by cooling elements 29, the strip making a plurality of passes to achieve the desired rate of cooling. Zone 7 effects rapid reheating to the annealing temperature, and the strip then returns to zone 4 where it is rapidly cooled, at the same time giving up its heat to the incoming strip. In the modified form of Fig.2 (not shown) the strip, after the intermediate cooling stage, is returned to the initial heating zone to be reheated to the annealing temperature. Vibratory energy may be applied to the strip undergoing treatment either by an ultrasonic transducer transmitting energy to the metal bath in close proximity to the strip, or by causing the shaft of one of the pulleys over which the strip passes to be flexibly mounted, and causing it to vibrate by means of a magnetostrictive device.

Abstract: 516,929. Dyes ; dyeing. ELLIS, G. H., and OLPIN, H. C. July 13, 1938, No. 20777. [Classes 2 (iii) and 15 (ii)] Azo dyes are made by coupling a diazo compound with the pyrazolone nucleus of a pyrazolone coupling component, one only of the two components containing a single hydroxyl group which is both attached directly to an alkyl group and esterified to an acid ester of a polybasic acid, and both components being free from sulphonic and carboxylic groups. The esterified hydroxyalkyl group may be derived from a hydroxyalkoxy or hydroxyalkylamino group. The polybasic acid may be. sulphuric acid or phosphoric or phosphorous acids (cf. Specification 506,262), or an acid ester of an inorganic acid containing at least two acidic hydrogen atoms, e.g., a monoalkyl ester of phosphoric acid. The diazo components are preferably of the benzene series. The dyes obtained by coupling diazo compounds of sulphato-alkoxy derivatives of anilines and their nuclear alkyl, alkoxy and halogen derivatives with 1:3-dialkyl-, 3-alkyl- and 1-aryl-3-alkyl-5- pyrazolones and 1-aryl-5-pyrazolone-3-carboxylic esters, of which the 1-aryl group, if present, is a phenyl group which may be substituted by alkyl, alkoxy and halogen from a particularly useful group, as do also the dyes made by coupling diazobenzene or its nuclear alkoxy, alkyl or halogen derivatives with a 1-aryl-3-alkyl-5-pyrazolone or a 1-aryl-5-pyr-, azolone-3-carboxylic ester group ; these two groups dye cellulose acetate in fast yellow shades. The dyes may also be obtained by esterifying the corresponding hydroxyalkylated dyes to acid esters of polybasic acids. The products are dyes for cellulose esters and ethers, and may also be used for dyeing wool, silk and other animal fibres or mixed materials containing two or more types of fibre, e.g., cellulose acetate and an animal fibre or cellulose acetate and cotton or regenerated cellulose. In examples : (1) p-hydroxyethoxyaniline is esterified with sulphuric acid, diazotized and coupled with 1-phenyl-3-methyl-5-pyrazolone, (2) -p-#-hydroxyethoxyaniline is diazotized, coupled with 1-phenyl-3-methyl-5-pyrazolone and esterified with sulphuric acid or phosphorus trichloride, (3) 1-(p-hydroxyethoxyphenyl)-3-methyl-5-pyrazolone (made by condensing p-(hydroxyethoxy)- phenylhydrazine with acetoacetic ester) is coupled with diazobenzene and esterified with sulphuric acid, and (4) cellulose acetate fabric is dyed in a bath made of p-(#-sulphatoethoxy)- benzene-azo-1-phenyl-3-methyl-5-pyrazolone in water, salt being added to assist exhaustion. .Specification 181,750, [Class 2 (iii)] also is referred to.
