Title: Arrangement for recording information
IPC: H04N1/10
Filed: 1972-05-08
Abstract: 1387002 Electric synchronizing; control of two electric motors LICENTIA PATENTVERWALTUNGS GmbH 8 May 1972 [8 May 1971] 21422/72 Headings H2L and H2J An arrangement for recording information by a writing member moved in lines over a recording surface comprises first drive means to impart a continuous movement to the member to cause it to move in the line direction and second drive means to vary this movement in accordance with the positional deviation of the member from a desired position within the line, whereby the deviation is reduced substantially to zero to cause the writing member to run synchronously with the information that it is recording. In the application of the invention to recording stationary pictures or texts, the information signal can have a component to cause the writing member to move along the line and also a pulse-shaped reference signal whose occurrence with respect to time should coincide with the attainment of a reference position of the member in the line, for example at the end thereof. The aforementioned signal component controls the first drive means taking the form of a synchronous motor 12 in Fig. 1, which motor produces continuous linear movement of a light source 1 through a differential gear 11, axle 10 and cam 3. The positional deviation, when present, produces operation of a stepping motor 13 constituting the second drive means in one or other direction 14, so that the movement produced by the motor 12 is accelerated or retarded to cause the light beam 4, whose brightness is modulated in dependence on the information signal, to run synchronously with the reference pulse in this signal. The positional deviation may be determined by counting missing or too-frequently occurring periods of the signal component frequency and converting this count to a number of timing pulses controlling the motor 13. A further stepping motor 5 drives the photo-sensitive recording carrier 2, so that the beam 4 moves in lines thereon. The motors 5, 12, 13 are controlled by electronic switching means (not shown). The modification shown in Fig. 2 omits the differential gear and interconnects the members 10, 12, 13 so that the axle 10 is driven by the rotor 12a, the stator 12b is connected to the rotor 13a and is energized through slip rings 15 and sliding contacts 16, and the stator 13b is stationary. Gearing may be inserted between members 12b and 13a and between members 3 and 10. The first and second drive means can be combined in the form of a single stepping motor supplied from a first source with timed current pulses to produce continuous movement of the writing member in the line and from a second source with additional timed pulses dependent on the direction and magnitude of the positional deviation of the member to accelerate or retard its movement.

[Class 93] [Also in Group XX] A screen or other pattern is reproduced by applying a pattern resist to a layer or thin sheet of metal, attacking the metal at its unprotected places by iodine, bromine, or chlorine vapour, and dissolving off the metal halide formed. A coating of silver is applied to one side of a glass plate or flexible sheet, and the coating is covered with sensitized fish-glue by a whirling or dipping process. The layer is exposed under a desired pattern screen which is negative to the pattern required. The image is developed with ordinary water, and the unexposed fish-glue removed. The image is then stained to render it visible. After drying, the carrier and resist are supported downwardly over a shallow vessel containing iodine which slowly vaporizes and attacks the exposed silver. The fish-glue is removed by a strong solution of caustic alkali, and the silver iodide removed by a solution of sodium hyposulphite. Bromine or chlorine may replace the iodine in the above process. A screen may be formed upon a flexible carrier by transfer from a rigid carrier, the former being given a layer of varnish, Canada balsam, &c. and pressed into contact with the silver image on the rigid carrier.

Abstract: 746,387. Knitting-machines. COTTON, Ltd., W. July 3, 1953 [Aug. 30, 1952], No. 21856/52. Class 74 (2). To speed up the production of horizontally striped fabrics upon a straight-bar machine, yarn selection is effected during the knitting period of the course immediately preceding yarn change, and the speed of the machine is reduced during the latter part of the yarn draw period for that immediately preceding course and is restored to normal during an early period of the yarn draw period for the course in which yarn change occurs. Yarn selection and speed control are both determined by stops 34 ... 36 upon a common pattern chain 37, but the actual timing of the yarn change and the change of speed is controlled by cams 23, 54 upon the main shaft so that these times are related to the yarn draw and knitting periods of the machine. As described in connection with a machine having three carrier bars 1 ... 3, the bars are selectively operable by a bolt 4 mounted upon a rocking shaft 5. The shaft 5 is rocked to bring the bolt 4 into alignment with a bar 1 ... 3 under control of three star-wheels 13 ... 15 having lugs of different height and secured to ratchet-wheels. The ratchet-wheels can be intermittently rotated by pawls actuated by the cam 23, and a pawl bluffing member is provided for each ratchet-wheel and is moved under control of a pattern stop 34 ... 36 to permit the corresponding star wheel to be rotated, the rotation of the star wheel and, therefore, the rocking of the shaft 5 being timed by cam 23. Movement of any bluffing member is accompanied by movement of a rod 43 which by linkage 44 ... 49 frees a catch 50 from a roller 51 upon a truck arm 52 so that a truck 53 carried by the arm can engage the cam 54, which by means of linkage 152, 55 adjusts the brushes of the driving motor to reduce and restore the speed of the machine. One row of the studs 35 and an additional row of studs 137 may be provided for single-course striping.

Abstract: 800,982. Methods of generating steam. BARR, W. J. C. Dec. 20, 1956 [July 16, 1956], No. 21868/56. Classes 123(2) and 123(3) Steam is generated by the combustion of a mixture of hydrogen and oxygen fed to a combustion chamber A through pipes B, C and ignited therein by an electric spark, the resultant high temperature steam being passed to a de-superheating chamber E where water, in pre-determined quantities, is sprayed into it producing a larger volume of steam at a lower temperature which is fed through a pipe M to a series of turbines G, G1, G2. The exhaust steam from the turbines is led through a pipe H and is forced by an injector J into a regenerating chamber K from where it passes to another regenerating chamber L and in both of these chambers it is mixed with high temperature steam either produced bY the combustion therein of further quantities of hydrogen and oxygen or supplied thereto from the combustion chamber A, the latter also supplying steam to the injector J. The regenerated steam passes from the chamber L through a pipe M back to the turbines and provision is made for drawing off a quantity of the exhaust steam which may be used in other steam plant, released into the cooling water or condensed and heated by electrolysis to produce hydrogen and oxygen. The chambers A. E. K, L which may be of any shape but are preferably spherical, are provided with cooling water jackets supplied with water from a pipe O, the water returning to a pump E2 for injection into the chamber E. Small auxiliary combustion chambers may be connected to chambers A, K, L for use only when small quantities of high temperature steam are required and, if desired, high temperature steam may be fed direct to the turbines from chamber A.
