Filed: 1921-01-10
Abstract: 157,786. Hanauer, E. Aug. 22, 1913, [Convention date]. No Patent granted (Sealing fee not paid). Cylinder machines.-In order to reduce the overall length of a two-revolution cylinder machine to a minimum the delivery mechanism is reduced in length, whilst the inking-apparatus is arranged at the rear of the impression cylinder, and the impression cylinder and feed-board are arranged nearer to the front of the machine, so that all the above mechanisms are contained within the space occupied by the bed frame of the machine. As shown in Fig. 2, and in comparison with the usual arrangement of machine shown in Fig. 1, the length of the delivery mechanism from the take-off roller 18 to the extreme end of the delivery board 7 is reduced from about 2¢ times the length of the printed sheet to about 1¢ times this length, so that the delivery mechanism does not project beyond the end position 14 of the reciprocating frame 1. The consequent encroachment of the delivery board on the space ordinarily occupied by the inking- apparatus in front of the cylinder 5 necessitates the displacement of the inking rollers 6, ink trough 11, and the intermdiate rollers 12, 13, to a position shown in Fig. 2 to the rear of the cylinder 5. The latter is mounted directly over the driving gear 4 of the reciprocating frame 1, enabling the feed-board 8 to be mounted in a more forward position so that its rear end does not project beyond the end position 15 of the reciprocating frame. Specification 15840/03 is referred to.

Abstract: 538,569. Blowpipe burners. LINDE AIR PRODUCTS CO. Feb. 1, 1940, No. 1949. Convention date, March 3, 1939. [Class 75 (i)] [Also in Group II] Scale is removed from ferrous metal by surface heating by flames, which causes differential expansion between the upper and lower surfaces of the scale. The heat is derived from a burner H mounted on a wheeled carriage C adapted to be moved over a surface of a billet B to be treated. An oxyacetylene mixture is supplied by a blowpipe 22 having controlling valves 27, 28 and a shut-off lever valve 29. The wheels W are adjustably mounted by clamps 31 on frame members 32. Skids 36 of refractory material are mounted adjacent to the burner H, to space the burner about # inch from the surface. The burner comprises a solid block 40 containing passages for combustible mixture, and a lower strip 41 with long outlet passages 42, partly conical at 44 and partly cylindrical at 45. High-temperature flames are obtained by preheating in the passages of the block 40 and by providing an oxygen-acetylene ratio of 1.5 to 2:1. The mixture issues from the passages with a velocity between 600 feet per second and the velocity of flame propagation. Burners similar to H may be provided to direct flames against each of the four sides of a billet. If a cylinder or tube is to be treated, the burner may be stationary with the row of flames directed on a longitudinal portion of the surface while the cylinder or tube is rotated, or the burner may be curved to cover part or all of the circumference. Fig. 13 illustrates a semi-circular burner comprising an outer block 70, and an inner block 71 having outlets 42'. A baffle 72 perforated at 73 is arranged in the space between the two blocks. The burner is maintained at the correct distance from the surface S' by skids 36<SP>1</SP>. The cylinder R is moved longitudinally to remove scale from half its surface, and is turned through 180 degrees and the operation repeated. In another modification applicable for treating interior surfaces, the burner may be provided with slots 85, Fig. 16, whereby extra air is supplied for secondary combustion and to remove scale. Cooling water may be circulated through passages 88, 89. Separate air jets may be provided to remove scale, Figs. 17, 18 (not shown), or alternatively, electromagnetic means as in Fig. 19. Endless belts 100 with cross bars 104 are provided above the treated surfaces, and electromagnets 103 are arranged to draw the loosened scale on to the belts which carry it to a position where it drops off clear of the apparatus. The apparatus of Fig. 1 may be used for treating very thick scale by melting a series of closely adjacent holes in it in strips, after which the intervening strips can be detached mechanically.

Title: Method and Apparatus for Testing Cigarettes for Loosely Packed Ends.
IPC: A24C5/34
Filed: 1968-01-12
Abstract: 1,186,311. Testing cigarettes. R. J. REYNOLDS TOBACCO CO. 12 Jan., 1968 [31 Jan., 1967; 13 Nov., 1967], No. 1990/68. Heading A2C. In a method of testing the ends of cigarettes to determine the acceptability of the end textural fabrication thereof, a jet of air is directed towards an end of a cigarette to be tested and the pressure of air at a locality adjacent the nozzle opening is measured. In one embodiment, cigarettes 3 are conveyed on a suction drum 1 past a pair of test heads 4. Each head 4 is supplied by a conduit 5 with compressed air which passes through a fixed restriction 6 to a nozzle 7 and to a conduit 8. The conduit 8 leads to a diaphram type pressure sensitive switch 9. Actuation of either switches 9, by a pressure drop below a predetermined value in either conduit 8 due to the detection of a faulty cigarette end, causes a solenoid 10 to actuate a pneumatic ejecting mechanism 11 after a suitable delay. The nozzle 4 may be mounted so that its axis makes an acute angle x with the axis of the cigarettes 3 when tested, Fig. 3, to compensate for loss of air from the nozzle 7 in the intervals between the passing of cigarettes 3. In another embodiment, Fig. 4, compressed air at a regulated pressure is supplied by a conduit 24 to a central passage of a nozzle 20 and, via a fixed restriction and a conduit 26, to a peripheral passage 22 of annular cross-section. Conduits 24, 26 are connected to a fluid amplifier (29) that actuates a suitably delayed ejection mechanism whenever a faulty cigarette is detected. Alternatively a pressure sensitive switch may be used as in the first embodiment. The nozzle 20 may be angled as is the nozzle 4 in Fig. 3, or the conduit 26 may include a rotary valve (40) synchronized with the drum to close the conduit 26 in the intervals when a cigarette is not passing the end of the nozzle 20. Other forms of nozzles disclosed are: a nozzle with two adjacent rectangular openings; a nozzle having a central supply tube surrounded by a plurality of interconnected hollow sensing tubes; and two tubes set with their axes at an acute angle to each other and to the axes of the cigarettes to be tested. The cigarettes to be tested may be filter tipped, untipped, or may be double length with an interposed filter element.
