Title: Improvements in and relating to film marking devices
IPC: G03B21/43
Filed: 1930-09-20
Abstract: 357,767. Kinematograph films. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Hoxie, C. A. ; Alplaus, Schenectady, New York, U.S.A.) Sept. 20, 1930, No. 28159. Convention date, Sept. 20, 1929. [Class 98 (ii).] Apparatus for making a reference mark adapted to be both seen and felt on a moving photographic film 1 of the kinematographic or sound record type comprises a rotatable member 5 having spaced projections 6 and means for causing an initial rotation of such member in order to bring one of the projections into contact with the film, the further rotation of the said member so that the next projection is presented for engagement with the film being brought about by the movement of the film itself and the engagement therewith of a projection. The film 1 is supported adjacent the member 5 on a roller 3 having an annular recess 4 to receive the projections 6. The member 5, which is adapted to be actuated by a lever 8 under the action of a spring 12, is normally retained in the inoperative position by a spring-controlled detent 15 engaging one of a number of pins 7 projecting from the member 5 adjacent the projections 6. An arm 17 on the detent 15 engages a latch 20 which is pivoted at its upper end to a bell-crank lever 21 and is provided with a cam surface at its lower end for engaging a guide pin 23 under the action of a spring 22. The armature 25 of an electromagnet 26 is connected with one arm of the lever 21 so that when a switch 29 in the electromagnet circuit is closed the detent 15 is operated to cause, one of the projections 6 to engage the moving film. The continued movement of the film causes the projection to perforate or deform the film and rotates the member 5 so that a pin 7 engages a face 11 of the lever 8 and rotates such lever against the spring 12. The lever 8 subsequently rotates the member 5 until the detent 15 stops the next pin 7. Where several of these devices are connected in circuit with the same switch, successive operations of the switch may make a series of marks in any desired sequence on all the films whereby various portions of the films may be identified for subsequent matching. The invention is applicable when a positive film is to be made from two or more negative films or a combined motion picture- and sound record print is to be made from separate negatives.

Title: A process for obtaining sugar from cellulose or cellulose-containing substances
IPC: C13K1/02
Filed: 1929-09-18
Abstract: Cellulose-containing material such as comminuted wood with its natural water content or a reduced water content is decomposed and saccharified to fermentable sugars, by treatment under such conditions, e.g. low temperature and gaseous acids, that premature formation of sugar is avoided, and submitting it to an immediate rapid hydrolysis by indirect heating if desired in a closed vessel to temperatures above 50 DEG  C., preferably about 70 DEG  C., or at a higher temperature followed by cooling.  The material, in a loose, non-compact condition, or a solution obtained from it, is then extensively freed from hydrochloric acid and converted in known manner, e.g. heating in the presence of water, to monoses.  The cooling of the material to be decomposed may be effected by introducing the hydrochloric acid gas or gaseous mixture containing hydrochloric acid gas in a strongly cooled condition or by using liquefied hydrogen chloride.  The Specification as open to inspection under Sect. 91 (3) (a) states that this hydrolyzing process may also be applied to decomposition products which have been obtained from cellulose-containing materials by methods other than those described above.  This subject-matter does not appear in the Specification as accepted.

Abstract: 745,483. Semiconductor saw-tooth generating and amplifying circuits. RADIO CORPORATION OF AMERICA. Oct. 15, 1953 [Nov. 13, 1952], No. 28533/53. Class 40 (6). In a circuit for a semiconductor amplifying device 60<SP>1</SP>, such as a transistor having a low or non-linear input impedance with respect to a saw-tooth generating stage 50<SP>1</SP>, a series resistor 30 is included having a resistance at least five times larger than the input impedance. Capacitor 21 is alternatively rapidly discharged over limiting resistor 19 and slowly recharged over resistors 17, 20 to geneiate a saw-tooth waveform at terminal 29. Since the base impedance of the amplifier tiansistor 35 falls rapidly with increasing base current, the series resistor 30 enables the current fed to it to follow the saw-tooth voltage with increased linearity. The resistor 30 also prevents the low base impedance of the amplifier from loading excessively the generator 50<SP>1</SP>. Synchronizing pulses are applied over terminal 23.

Abstract: 844,364. Copying documents. ELLAMS DUPLICATOR CO. Ltd. Oct. 5, 1956 [Oct. 6, 1955], No. 28568/55. Class 100(2) A method of producing copies of matter to be copied comprises forming a mirror image of the matter, in a composition containing a soluble dye, on a carrier, and producing impressions on copy sheets by bringing the copy sheets into contact with the carrier, each copy sheet having a solid non-hygroscopic surface coating containing a substantially non-volatile solvent for the dye, whereby an impression is produced on the coating in the absence of moisture other than that present in the atmosphere. The solvent used is a non-volatile long chain fatty alcohol (e.g. oleyl alcohol) and the coating, which is anhydrous, includes a binder for the solvent consisting of nitrocellulose and may also include a white pigment of titanium dioxide (to reduce the transparency of the coated paper) and a precipitant (e.g. phosphomolybdic acid). In an example 100 parts by weight of titanium dioxide were ground into 250 parts of oleyl alcohol and added to a solution of 60 parts of a mixture of 70 parts of nitrocellulose and 30 parts of methylated spirits, in 360 parts of n-butyl acetate. The resulting liquid was applied to one surface of a white paper and the paper heated to draw off the n-butyl acetate and methylated spirit. The coated paper was then cut into copy sheets. The mirror image was formed by coating a melted mixture of 60 parts of methyl violet, 10 parts of carnauba wax and 30 parts of petroleum jelly on paper, placing the paper coated side upwards on a metal base and placing on top a piece of white, smooth surface paper which forms the carrier. The latter was then written on with a stylus so as to transfer the coating on to the carrier in the form of a mirror image of the matter inscribed. Where a precipitant for the dye is included in the coating on the copy sheet the coating is made as above except that before application to the paper a solution of 3.85 parts of phosphomolybdic acid in 385 parts of methylated spirit is added.
