Abstract: 479,423. Feeding sheets. SCHNELLPRESSENFABRIK AKT.-GES. HEIDELBERG. Sept. 20, 1937, No. 25448. Convention date, Feb. 1. [Class 100 (i)] A sheet-feeding device in which a sheet to to be fed is seized at its forward end by grippers 17, 18 mounted upon a carriage 10 which is reciprocated over guides 19<1> in such a manner that the grippers extend upwards through slots 1<1> in a feed-table 1 is constructed with means for reciprocating the gripper carriage from a state of rest consisting of link members 5, 7, 11 so designed that a straight-line motion is given to the grippers, the link 5 which is connected to the driving-device being connected to a slide 4 so as to guide the lower pivots of the links 5, 7 in a straight line. The straight-line motion is obtained by pivoting the link 11 to a fixed pivot 13 and to the link 5, and in such a manner that the distances x<1>, x<2>, x<3> are all equal. To reciprocate the grippers, an extension 5<1> of the link 5 is connected to a crank 29 by means of a connecting- rod 28, the crank 29 being oscillated through an angle of somewhat more than 180‹ by means of a pinion 30 and rack 31 reciprocated by an eccentric on the main driving-shaft 23. The grippers 17, 18 are actuated in known manner and may be replaced by suction devices, and on the return of the carriage 10 the grippers are lowered beneath the slots 1<1> by depressing a guide 21 by means of a cam 22 on the shaft 23. The guide 21 controls the lower gripper member 17 which is fitted with a roller 20 moving over the guide. The shaft 23 is also fitted with a cam 24<1>, which engages a roller 25 on an arm 26 carried by the pivot pin 6 of the link member 5, and so the link members are locked without clearance in their extreme positions.

Title: Improvements in or relating to tobacco-delivery systems for cigarette-making and other machines
IPC: A24C5/39
Filed: 1929-08-27
Abstract: 338,908. Grupe, W. F. Aug. 27, 1929. Cigarette-making machines.- In means for feeding tobacco to machines for making cigarettes, packeting tobacco, &c., and comprising a conduit through which the tobacco is conveyed and discharged at intervals to separate machines, as described in Specification 324,640, the means for discharging the tobacco to the machine hoppers is automatically controlled by the weight of tobacco contained in a scale-pan about to be delivered to the hopper, or by the weight of tobacco within the hopper itself. Fig. 1 shows the conduit 10 along which tobacco is carried by conveyers 11, which are provided over each machine hopper 12 with guiding-shoots 17, adapted to be held by a balance weight 19 in either of two positions, one for delivering the tobacco to the next conveyer 11, and the other for delivering it to a scale-pan 23 as shown. When the tobacco in the pan 23 overbalances a counterweight 22, the pan discharges into the hopper, and the shoot 17 is moved by linkage 25, 24, 28 to its other position. The discharging of the pan is further regulated by a snail cam 33 and linkage 31, 32, 30, the cam being rotated by ratchet mechanism so as to allow the weight 22 to rise when a predetermined number of cigarettes &c. has been completed, and afterwards to return the pan and shoot to the filling position. In a modification, the band 13 forming the base of the hopper is pivoted at one end and counterweighted so as to control the position of the shoot 17, which delivers directly into the hopper. Fig. 2 shows another form, in which a pair of scale-pans 40 are pivoted at 41, about which they rotate when a catch 42 is released, so that the full pan is discharged and the other brought into the upper position for filling. The catch 42 is actuated by a wedge 44 connected to a counterweight 37 of the hopper base 13, and also by a pin-and-slot connection 47 to a cam rotated by the machine. In another modification, the scale-pan is arranged to control the speed of rotation of the cam 33; or again the scale-pan may be replaced by a conveyer belt counterweighted so as to discharge into the hopper. An air blast, a chain carrier, or a bucket conveyer may be used instead of belt conveyers to feed the tobacco along the conduit 10.

Title: Improvements in or relating to the distillation of coal tar
IPC: C10C1/04
Filed: 1956-08-27
Abstract: <PICT:0801907/III/1> In order to separate individual components boiling above 300 DEG  C. from coal-tar, the tar is first distilled to remove the components boiling below 300 DEG  C., it is then submitted to fractional distillation under reduced pressure in a column 1, the sump-liquid being circulated through a tube furnace 5 and the sump of the column, and a fraction having a boiling range of 300-400 DEG  C. (at normal pressure) is withdrawn as distillate from the head of the column, and finally this distillate is submitted to vacuum fractionation in a series of colums 2, 3, 4 whereby anthracene, acridine and carbazole fractions are obtained as head products from columns 2, 3 and 4 respectively, and fluoranthenepyrene fraction is withdrawn from the base of column 4.  The presence of fluoranthenepyrene in all the columns acts as a buffer agent against the thermal decomposition of anthracene, acridine or carbazole.  Each of the columns 2, 3 and 4 is heated by circulating part of the sump liquid through tube furnace 6, 7 or 8 respectively.  Steam may be injected into all the columns in order to assist the distillation. Part of the fluoranthene-pyrene fraction withdrawn from column 4 is used, after cooling to about 120 DEG  C., in scrubber 13 as a washingagent for the gases flowing to the vacuum pump; the liquid is then added to the distillate from column 1, and distilled in column 2.  In an example, column 1 is operated at a pressure of 30 mm. Hg., the temperature in the sump of the column is maintained at 350-380 DEG  C., and the head temperature is maintained at about 240 DEG  C. The pitch withdrawn from the base of column 1 has a solidification-point of about 80 DEG  C. Columns 2, 3 and 4 are all operated at a pressure of 200 mm., the head temperatures being 270 DEG , 280 DEG  and 290 DEG  C., respectively. The head product of column 2 has an anthracene content of about 25 per cent.  The head product of column 4 has a carbazole content of 36 per cent. Specifications 14230/13, [Class 32], 318,897, [Class 32 (1)], and 698,340 are referred to.
