Title: Improved fulling machine of the roller type
IPC: D06C17/02
Filed: 1936-12-30
Abstract: 482,626. Fulling hats &c. CASSE, M. Dec. 30, 1936, No. 35704. [Class 63] In a machine for fulling hats &c. having two sets of rollers 3, 4, at least one set is oscillated about its axis in addition to its uniform rotation, while it or its co-operating set of rollers is reciprocated axially, the oscillations and reciprocations having the same frequency, or being multiples or submultiples of each other. In the machines shown, the oscillating movement is at a maximum when the reciprocating movement is zero and vice versa. As shown in Fig. 1, the hat blanks are carried through the rollers by an endless band 24 and returned to the starting position between the band 24 and a second band 26. The upper rollers 4 are mounted in two casings 5 which are reciprocated along with the rollers 4 on two cross-rods 8 parallel to the rollers by eccentrics on the drive shaft 13 carried by one of the casings 5. This shaft 13 carries worms for driving the rollers 4 and a wobbling end on which is a box 14 connected by a link and ball joint with the bed of the machine. The shaft 13 vibrates endways at each rotation and thus oscillates the rollers 4 in unison with their axial reciprocation. In the machine shown in Figs. 5, 6, and 9 the hat blanks &c. are fed to the rollers 3, 4 by a band 24, and after passing through these rollers are delivered by a guide 106 on to a second band 107 which returns them to a position whence they can be transferred to the band 24. The main shaft 30 has a number of alternately opposed eccentric parts which, through connecting rods 31, axially reciprocate the lower rollers 3, half in one and half in the other direction to reduce vibration. Through skew gearing 45, 46 the shaft 30 drives a vertical shaft 47 carrying two opposite eccentrics 48, 49 which reciprocate in opposite directions (to reduce vibration) two intergeared oppositely rotating shafts 54, 55 which drive and give an added oscillation to the lower rollers 3 through worm gearing 10, 9. The shafts 54, 55 are driven from the worm shaft 65 driving the upper rollers 4 by either a belt 60 and pulley 62 or a belt 61 and pulley 63 under the control of clutches and a hand wheel 74. The upper and lower rollers 4, 3 may thus be run at will at the same or at different speeds. The shaft 65 is driven by belts 79, 80 from the main shaft 30. The upper rollers can be lifted by racks and pinions 102, 101 and a hand wheel 98.

Title: The maintenance of a desired mean temperature in a length of material
IPC: G05D23/24
Filed: 1965-08-19
Abstract: 1,104,719. Automatic temperature control for annealing processes. SIEMENS-SCHUCKERTWERKE A. G. Aug.19, 1965 [Aug.19, 1964], No.35717/65. Heading G3R. A system for automatically maintaining constant the temperature of a length of material such as a travelling wire in an annealing process comprises means for measuring the electrical resistance of the length and using the measurement to control the current flowing in the material. The resistance of a length of wire 6 is measured by producing two voltages, one, by means of a transformer 7 representing the voltage across the length of wire 6 and the other by means of a transformer 8 representing the current flowing through the length of wire 6. The two voltages are rectified and applied in opposition to linearizing resistors 11, 12 and from the tapping on the resistor 12 is taken the voltage representing the resistance of the wire 6. This voltage is used, by way of an amplifier 13 to control the supply of current to the wire by means of a transducer or thyratron device 5, the current heating the wire to the desired temperature when the voltage from the tapping on the resistor 12 is zero, that is when the resistance of the length of wire 6 has the requisite value. A resistance may be connected in series with resistor 12 to introduce an adjusting factor into the system.

Title: Process of improving the resistance to corroding agents of aluminium base alloys
IPC: C22C21/06
Filed: 1933-12-22
Abstract: 432,351. Improving aluminium alloys. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Dec. 22, 1933, No. 36151. Convention date, Dec. 24, 1932. [Classes 72 and 82 (i)] In a process for improving the resistance to corroding agents of aluminium base alloys containing 3-16 per cent of magnesium, the alloys are heated to temperatures between the solidification point and the temperature range in which the change of solubility in the solid state of magnesium becomes noticeable with decreasing temperature and thereafter subjecting the alloy, preferably after chilling, to an annealing within a temperature range defined by the hatched portion of the accompanying phase diagram, thereby producing a segregation in the alloy of # particles rich in magnesium as compared with the basic alpha crystals, in a highly dispersed form and in a state of uniform distribution throughout said basic alpha crystals. Instead of the annealing, the alloy may be subjected to an artificially strongly retarded cooling down to at least 100‹ C. The alloys may also contain 0À1-2 per cent of manganese and up to 1 per cent of silicon. The alloys may be cold worked between the first heating and the annealing or before the first heating. In an example, an aluminium base alloy containing 8À8 per cent of magnesium and 0À4 of manganese was heated at 450‹ C. for 24 hours, quenched and then annealed at 320‹ C. for 1 hour.

Title: Process and apparatus for electrophotographic copying by transfer of electrostatic images
IPC: G03G15/18
Filed: 1973-07-30
Abstract: 1433350 Transferring latent images MITA INDUSTRIAL CO Ltd 30 July 1973 [31 July 1972] 36165/73 Heading G2H In a method of charge image transfer electrophotography employing a sensitive member having a conductive base 1, a photo-conductive layer 2 and a transparent insulating layer 3, the surface of the member is first charged primarily overall (using a direct current corona 5), the surface is then exposed to an image having light areas L and dark areas D and simultaneously or subsequently is subjected to a secondary charging (using an alternating current corona 9). The photoconductive layer is then treated (e.g. by overall light exposure) to eliminate the charge at the interface between the photo-conductive layer and the insulating layer, the resulting electrostatic image is transferred by contact to a transfer sheet which is then developed and fixed in the conventional manner. The characteristics of the alternating current used for secondary charging and/or the secondary charging time are chosen so that the electrostatic image formed on the surface of the member after dissipation of the interface charge has the same polarity as the polarity of the primary charging and so that the potential of the light areas L of said image is substantially equal to the "untransferable upper limit potential" and the potential of the dark areas D are higher than the said limit potential. The "untransferable upper limit potential" is defined as the upper limit of the potential which does not permit the electrostatic image to be transferred for a copy sheet by mere contact. A multi-colour electrophotographic apparatus employing this method comprises a sensitive surface A mounted on a drum 1 for circulation past primary charging station 4, a secondary charging and colour exposure station 28, an overall exposure station 39 and an electrostatic image transfer station M. Image-receiving material 10 is fed from a roll by a series of rollers, cut to a length corresponding to the length of the original by cutters 50, 51, and taken up by a suction drum 49 which advances it past the transfer station M, a developing zone and a fixing zone 71. To effect multi-colour reproduction the receiving sheet is circulated a plurality of times past the transfer station M, each time picking up one colour separation image of the original and being developed with the corresponding colour developer from one of a series of liquid developer troughs 57, 58, 59 and 60 which are brought selectively into a position above cams 69 and 70 by a transport device 56. Operation of the cams raises the selected trough into a developing position with a development electrode 65, 66, 67 or 68 adjacent the surface of drum 49. The images are fixed by heat from heaters 72 and the finished sheet is stripped from the drum by a device 73. The colour separation images are formed by positioning one of a series of coloured mirrors 34, 35, 36 and 37 in the path of light from an original a.
