Title: Method of and apparatus for transporting cinematographic film
IPC: G03B1/12
Filed: 1973-05-10
Abstract: 1423254 Transporting cine-film K VOCKENHUBER and R HAUSER 10 May 1973 [10 May 1972] 22421/73 Heading G2E Apparatus for intermittently feeding a cine-film comprises a film-moving device e.g. claw 4, for transporting successive film frames within a predetermined recurring period, and control means which prevent predetermined actuation of the claw so that the film is transported at at least two different frequencies in the said period. In Fig. 1 the in-and-out and up-and-down movement of claw 4 is controlled by a cam 5 driven by shaft 1. This shaft also drives, via a worm wheel 6 and worm 8, a further shaft 7 carrying cams 11 to 14, which are axially shiftable on shaft 7. The claw 4 is prevented from engaging sprocket holes 9 in the film 10 by an extension 17 on a bent carrier 16 engaging the claw. The movement of carrier 16 is controlled by follower 15 engaging cams 11 to 14. These cams give a frequency of 9, 6, 3 and 1¢ frames/sec. respectively. In operation the cams are shifted axially so that the follower 15 senses, for example, cams 11 and 12 on alternate rotations of the shaft 7 to give a recurring period in which the film is transported at a frequency-of 9 and then 6 frames/ sec. In an alternative embodiment the cams and follower are replaced by an electromagnet, controlled by an impulse generator, which attracts an armature on the claw to prevent the claw engaging in the sprocket holes. As with the cams, the electromagnet is energized so that the film is transported at at least two different frequencies in a recurring period.

Abstract: 894,317. Weighing apparatus. ZAVODY V.I. LENINA, PLZEN, NARODNI PODNIK. July 4, 1959, No. 23062/59. Class 143. In an automatic feed weighing system for cupola furnace charging, the weight of a charge is automatically compensated for any overload fed in the preceding charge. The compensating device comprises a lever 4 which is connected to the weighbeam 1 of the scale 13 by which the charges are weighed and which carries a rack 5 acting on a pinion 6. The pinion 6 carries a pawl 8 which cooperates with a ratchet on a disc 7 to rotate the latter as the weighbeam 1 turns until a pin 10 on the disc operates a switch 11 by which the cut-off of feed to the scale is effected. A fixed pawl 9 co-operating with a second ratchet on the disc prevents its reverse rotation when the scale is unloaded so that the amount by which the pin 10 overruns the position of the switch 11 in one weighing causes a corresponding shortening of its travel to cut-off position in the next weighing. In the apparatus shown the weighted bell-crank lever 15 operates to reduce the sensitivity of the weigher when out of balance.

Title: Improvements in or relating to the manufacture of aliphatic acids and their esters
IPC: C07C51/12
Filed: 1929-07-27
Abstract: 337,053. British Celanese, Ltd., and Bader, W. July 27, 1929. Acetic and other aliphatic acids and their esters; esters of phosphoric acid; ethers.- Aliphatic acids and their esters, for example, acetic acid and methyl acetate, are obtained by mixing liquid methanol or other aliphatic alcohol with one or more acid catalysts, namely, inorganic acids or inorganic acids containing organic groups, or their acid salts, and submitting the mixture to the action of carbon monoxide at 200‹-450‹ C. and at pressures up to 300 atmospheres. In a preferred method of carrying out the invention, methanol, preferably anhydrous, from a vessel 5 is mixed with phosphoric acid in a steam jacketed chamber 1 at 60‹-90‹ C. to promote, complete or partial esterification, and then passed to a jet 11. Carbon monoxide and steam are introduced into a preheater 12 by pipes 13 and 14 respectively, and pass to a gold- or graphite-lined reaction tube 2, heated to 300‹- 400‹ C., carrying with them methanol from the jet. The reaction products pass to a separator 15, where phosphoric acid separates and is returned to mixing chamber 1. Volatile products are condensed in a condenser 17, and remaining vapours are absorbed in charcoal in a tower 19. The gas is then passed through a pump 3 for recirculation. Esters present in the reaction products may be saponified by means of water in the presence of sulphuric acid, or, preferably, phosphoric acid at 150‹-300‹ C. to produce an acid and an ether. Specifications 283,989 and 284,582 are referred to.

Patent GB-663678-A (GB)
Title: Improvements in or relating to the stabilisation of organic acid esters of cellulose
IPC: C08B3/22
Filed: 1949-09-07
Abstract: Organic esters of cellulose in the solid phase are stabilized by heating under pressure to a temperature above 100 DEG  C. with a dilute aqueous solution of an unsubstituted monocarboxylic acid, the ester remaining undissolved throughout the treatment.  The solution of the acid is regarded as dilute if it does not dissolve by itself the ester at temperatures above 100 DEG  C.  The preferred monocarboxylic acids are the lower fatty acids, formic, acetic, propionic and the butyric acids, and it is advantageous to employ the acid corresponding to the ester to be stabilized.  The process is applicable in particular to cellulose acetate, propionate, butyrate, acetate - propionate and acetatebutyrate and is especially useful with the less easily wetted esters such as the propionate.  When the process of the invention is to be applied, the ripening of the ester should be carried out at a temperature above 100 DEG  C. under pressure after partial or complete neutralization of the catalyst. The ripened ester is precipitated and stabilized in an autoclave or continuously by passage through a heated tubular vessel.  The concentration of the organic acid is preferably between 1 and 25 per cent.  The suspension of the ester comprising 2 to 25 parts ester per 100 parts acid is heated to 110 DEG  to 170 DEG  C. or higher, corresponding to 10 to 100 p.s.i.g. for 15 minutes to 5 hours.  The stabilization may be effected in stages if desired, each using fresh acid.  After stabilization, the ester is drained, washed with distilled or demineralized water and dried.  The loss in viscosity due to the process may be reduced by addition of a small proportion of a magnesium salt of a weak acid such as magnesium acetate or propionate as a buffer. Alternatively an alkali or alkaline-earth salt of a weak organic acid such as sodium or lithium acetate or magnesium citrate may be added to the ester after stabilization in amount to give an alkalinity of 50-200 p.p.m. calculated as calcium carbonate.  In an example (all parts by weight) 10 parts of ripened cellulose propionate (64.5 per cent propionyl calculated as propionic acid) and 100 parts of 10 per cent propionic acid are introduced into a steam-jacketed pressure vessel fitted with a stirrer and sealed. Steam is admitted to the jacket until the pressure within the vessel is 25 p.s.i.g. (about 130 DEG  C.).  After stirring for 2 hours at this temperature, the acid is discharged and the ester washed with water of low mineral content to free it from propionic acid, and then dried.  Specifications 620,726 and 657,827 are referred to.

Abstract: 639,821. Phase differences measuring. SPERRY GYROSCOPE CO., Inc. Sept. 8, 1945, No. 23206. Convention date, Sept. 8, 1944. [Class 37] [Also in Group XL (c)] The phase-difference or time relationship between a set of recurrent pulses and a periodic reference oscillation is determined by developing an auxiliary oscillation from the reference oscillation and applying it with the recurrent pulses to a gating valve to produce an output related to the phase difference between the auxiliary oscillation and the pulses, and applying this output to operate an indicator and to adjust the phase of the auxiliary oscillation to bring it more into phase with the pulses. As shown in Fig. 1, radar pulses received at 17 are amplified at 19 and applied to render valve 66 conducting during their duration; the reference oscillations from generator 13 are applied over phase-shifting stage 37 to develop a saw-tooth oscillation in 36 which is applied to valve 66, so that it passes pulses whose amplitudes vary with the relationship of the pulses from 19 and the saw-tooth oscillation from 36; the output from valve 66 is smoothed and applied to valve 45 acting as a variable resistance in phase-shifting circuit 37. Thus, the phase of the oscillations from 13 is varied to vary the phase of the saw-tooth generator 36 until the output of valve 66 is just sufficient to maintain the necessary phase difference between the saw-tooth oscillation and the pulses from 19 to produce that output. A voltmeter V indicates this output which is a function of the phase difference between the pulses and the oscillator 13. The phase shifter may consist of two circuits in series, Fig. 4 (not shown). Specification 562,513, [Group XL], is referred to.
