Title: Method of and apparatus for treating webs of fibrous material for tobacco product filters particularly cigarette filters
IPC: D21H11/14
Filed: 1971-06-29
Abstract: 1340942 Corrugating fibrous webs CELFIL CO ESTABLISHMENT 29 June 1971 [13 May 1971] 30443/71 Headings D1S and D2B [Also in Division A2] A web of fibrous material is treated to render it suitable for being gathered in the transverse direction into a filter cord which can be subdivided into filter rods for tobacco products, e.g. cigarettes, by first stretching the web in a first direction in a plurality of consecutive parallel areas so that the fibre structure is loosened and then stretching the web in another direction in a plurality of consecutive parallel areas, at least one of the stretched areas being oriented substantially in the longitudinal direction of the web to facilitate gathering the latter while the continuity of the web is preserved despite the stretched areas. As shown in Fig. 1, a paper web 1 passes, from a supply roll 2, between rolls 3, 5 and is moistened with a liquid 4, e.g. water, alcohol or acetone. Alternatively, moistening may be effected by spraying or the use of wet or hot steam. The web passes between intermeshing, but not contacting, rolls 6, 7 provided with transverse ribs for longitudinal stretching and then between intermeshing, but not contacting, rolls 8, 9, 10 provided with annular ribs for longitudinal grooving and transverse stretching of the paper 1. The speed of the rolls 6, 7 is adjusted to that of the drive of the web 1 and the rolls 8, 9, 10 are rotated at a higher speed than the rolls 6, 7 by an adjustable stepup gear, possibly controlled by a feeler bearing on the web 1. If a volatile liquid 4 is used, it may be recovered by a hood 14 and a tube 15. The web 40 passes over guide rollers 11, 12 to a cording machine identical to that shown in Fig. 10 of Specification 1,276,933. Each roll 6, 7 may comprise a hollow core 14 provided with grooves 15 evenly distributed over its circumference in which heating rods 16 in insulating sheaves are arranged. Rings 17 having transverse exterior ribs are slipped over the core 14 and are forced, by a compression spring, against a stop ring 18. In a modification (not shown), the roll 10 is omitted. In further modifications, the rolls 6, 7 are replaced by rolls having ribs similar to a helical gear so that the first stretching is effected in an oblique direction, Fig. 10 (not shown), or by rolls which form stretched areas lying in two oblique directions, Figs. 11 and 12 (both not shown).

Abstract: 1,047,815. Change-speed gear; friction clutches. FICHTEL & SACHS A.G. Aug. 4, 1964 [July 19, 1963], No. 30460/64. Headings F2C and F2D. [Also in Divisions D1 and H2] A pole-changing motor 10 driving a washing- machine is operated at low speed by actuating switch 66, a sun-wheel 34 driving planet pinion carrier 32 at reduced speed. The member 32 is coupled through free-wheel device 36 to output shaft 38 and drum 64. Actuation of switch 70 operates the motor at high speed, shaft 24 driving spring 44 and weight 48 which moves into its outer radial position when driven at the higher speed, against the force of spring 49. Stop yoke 54 engages in slot 50 so that spring 44 is drawn together and is applied tightly to annular body 42. The shaft 38 now rotates with shaft 24, which corresponds to a high transmission ratio, the shaft 38 overtaking the member 32 due to the free-wheel device 36. Actuation of switch 74 returns the motor to low-speed operation after a predetermined period. The speed of shaft 24 falls to such a value that the weight 48 tends to return to its radially inner position, but is held in its outer position since yoke 54 engages slot 50. The speed of shaft 38 is now determined by low motor speed and high transmission ratio, which corresponds to a value between the minimum and maximum values of output speed. As long as the motor 10 supplies torque, the slot 50 remains in engagement with the yoke 54. Only after the motor is de-energized can the weight 48 return to its radially inner position.

Abstract: 1,146,910. Determining 1 -phenyl-3-pyrazolidone photo-electrically. RUMANIA STATE BOARD FOR CULTURE and ART. July 8, 1966 [July 13, 1965], No. 30676/66. Heading G1A. 1-phenyl-3-pyrazolidone in a photographic developing solution is determined by diluting the solution with a buffer solution and measuring the blackening effect produced on uniformally exposed film by the diluted solution. Preferably the blackening is measured whilst the film is in the developing solution. The developing solution is diluted to a 1 -phenyl-3-pyrazolidone concentration in the range 0À003 to 0À05 g/1 by the addition of a buffer solution comprising 200 g/1 crystallized sodium sulphite; 2 g/1 borax; 3 g/1 boric acid and 1 g/1 potassium bromide. The diluted solution is introduced into a tank 3 having an overflow level regulator 10 and means for supporting a film 2 which has been exposed on half its width. The film blackening is measured by comparing the outputs of photo-cells 7 one of which receives light through the film and the other directly from a source 8. Pushing the handle 20 brings the film 2 into the solution and at the same time starts a clock 8 so that the blackening can be read off meter 19 after a predetermined time, and used to determine the concentration of 1-phenyl-3- pyrazolidone from a calibration curve produced using known concentrations. Diaphragms 6 are provided for setting the zero of meter 19.

An arrangement for eliminating the need to transmit each of a sequence of "blank" characters separately to a remote terminal employs a coding in which a special character followed by a numeric character specifies the run-length of blanks, and on recognition of the special character at the terminal the number specified by the following character is countered down once at each character time until it reaches zero, whereupon succeeding characters are again accepted for display or printing &c. in the usual way. As shown each character on receipt at 16 is passed into buffer 30 and then normally read out through gate 78 into cyclic memory 10 in a position following that marked by a cursor bit (the first bit of each character is reserved for this). The cursor bit is then shifted by erasure over lines 50, 62 and re-entered in the next position over line 86 (flip-flop 74 being normally in zero state and thus enabling gate 84). The special character when recognized at 34 sets 70, and the cursor bit shifted and the next character entered into 30 as usual, but 74 is set to prevent the "number of blanks" character being transferred from 30 to 10. Instead this number is circulated through gate 106 now enabled over 104 via the "subtract one" circuit 112, and this action continues until it is counted down to zero when 74 is reset over line 38. In the embodiment described the display device is a CRT alphanumeric display.
