Title: Improvements relating to intaglio printing
IPC: B41F9/00
Filed: 1928-12-17
Abstract: 326,552. Allman, P. Dec. 17, 1928. Rotary intaglio machines; gripper mechanism; impression surfaces. - A sheet-fed intaglio rotary printing- machine prints a sheet for each rotation of the printing-cylinder by employing an impression cylinder R formed of two or more impression surfaces b separated by gaps, each surface b receiving a sheet from a feed table H for each rotation of the printing-cylinder P, which is preferably of the kind in which an intaglio plate is clamped thereon, the gap in this cylinder coacting with the gaps in the impression cylinder R. The sheets are delivered from the top of cylinder R by a stripper t and delivery bands t<1>, Fig. 6. The sheet grippers are maintained in the open or closed position by a spring s acting on flats f<1>, f<2> on the gripper shaft g which is rotated by fixed pins c<1>, Fig. 1, or c<2>, Fig. 6, to close and open the gripper respectively. The impression surfaces are fitted with blankets b which are held on one side of one gap by an anchoring device b<1>, Fig. 6, and at the other side of the gap by a tensioning rod r fitted with a ratchet r<1> and pawl r<2>. The cylinder P is fitted with inking-devices I, and doctor blade adjusting mechanism B, and is driven by gearing from a motor M. The cylinder P is geared to the cylinder R by gears which cause the cylinder P to make three complete revolutions for each revolution of the cylinder R. Tripping-arrangements.-The printing-cylinder. P runs freely on an eccentrically disposed shaft fitted with a lever arm b<2> which can be moved from the full line or printing position to the dotted line or tripped position by means of a lever k<1> acted on by a spring l tending to move the cylinder P out of contact with cylinder R. To enable the tripping mechanism to be operated at any instant but to function only when the gaps of the cylinders are in register, the! movements of lever k<1> are controlled by means of stops z<1> on a disc z on the impression cylinder. The lever k<1> is held in full line position by a projection k<3> engaged by a pawl w, which is released to allow the cylinders to be tripped by means of a link u<1> connected to a cam u pivoted to a lever o operated by pedal mechanism which moves the cam u into the path of a stop z<1> which effects the release of the pawl w. The lever k<1> is returned by the operation of one of the studs z<1> on a jaw h<2> on thrust pieces h pivoted to the upper end of the lever, the jaw being moved into the path of the stud by operating the lever o so as to raise its end o<2> and cause it to act on a projection h<1> attached to the thrust piece h.

Title: Improvements in navigable waterways
Inventor: LUNDGREN HELGE
IPC: E02B3/04
Filed: 1958-11-19
Abstract: 877,057. Groins control of silt deposition. CHRISTIANI & NIELSEN A. S. Nov. 19, 1958 [Dec. 2, 1957], No. 37294/58. Class 68(2). A means for influencing the movement of solid matter along the sea floor comprises a device situated on the seabed which produces eddies and increases the depth of the region immediately above the sea bottom in which solid matter is suspended due to the oscillatory motion of the water. Two devices are described comprising (a) Non-oriented artificial roughness in which staggered rows of rectangular blocks 1 (Fig. 1) are placed on the sea bed with their longitudinal axes transverse to the wave direction. Fig. 2 is a section through Fig. 1 and shows the formation of an eddy 9, due to the motion of a wavecrest 4 and hence the body of water under the wave, in the direction of the arrow 25. The velocity distribution of the water particles is indicated by the lines 5 and 6. When the following trough passes the velocity distribution will be as shown by the arrows 11 and 12 in Fig. 3, new eddies 14 will be formed and the eddies 9 will move upwards and backwards and at the same time expand so that the depth of the turbulent region 15 is increased to that shown at 16. (b) An oriented artificial roughness in which unsymmetrical blocks 17 are used. This construction results in the formation of eddies only on the forward motion of the wave in the direction of the arrow 25 (Fig. 7). The arrows 21, 22, 23 and 24 which indicate the direction of water movement show that the top most layers of water 21 move against the direction of wave propagation and the lowermost layers 22 normally move in the direction of wave propagation, but due to the action of the blocks 17 a water movement opposite to the direction of wave propagation is induced which results in material being deposited at 26. A number of shapes of block which will produce these effects are described and illustrated and also the device shown in Fig. 25 (not shown) in which a pivoted plate 53 swings to the position shown, when the water moves in the direction of the arrows and results in the formation of the eddy 9, but pivots to a nearly horizontal position on reverse movement of the water and allows suspended matter to pass through. An arrangement of oriented and non-oriented artificial roughness is illustrated in which the blocks are disposed so as to keep a harbour mouth free of silt (not shown, see Fig. 27).

Piped buttonholes.-An attachment for use with a sewing machine in stitching to base material W a piping blank B having a pair of opposed inwardly folded edges, the blank being secured to material W by two lines of stitching S arranged parallel to the folds F, comprises a baseplate formed with a pair of parallel openended needle slots and provided on one face with friction means, means for clamping a folded piping blank against the other face of the baseplate, the clamping means having a pair of slots registering with the slots in the baseplate, and releasable means for holding the clamping means in clamping relation with the baseplate. The baseplate 12 has a roughened lower surface 13 and is formed with a. pair of open-ended needle slots 16. Two clamping plates 20 are hinged at their outer edges on floating pivots 21, 23 carried at the opposite ends of springs 26 attached centrally to the baseplate by screws 27. Clamps 20, which are biased to the raised position by springs 28 mounted on the pivots 23, are formed with slots 30 which register with the slots 16 when the clamps are lowered, and the inner edges of the clamps are turned downwardly to form flanges 31. Edge-guiding strips 32 are secured to the baseplate by screws 33. Closing of the clamps is effected by means of a slide 34 mounted on a slide plate 19 extending from the baseplate. The slide is provided with a pair of arms 36, each of which is formed with cam surfaces 37, 39, 41 adapted, when the slide is moved inwardly, to act in sequence upon the clamps for turning the latter from the open vertical position to the closed horizontal position. In operation, the clamps are opened, a piping blank is placed therebetween, and the clamps are closed, when the edges of the blank are turned inwardly and the folds F abut the strips 32, the floating pivots serving to accommodate varying thicknesses of blank material. The loaded attachment is then placed in position upon the material W under a special presser foot 4 attached to the presser bar of a domestic sewing machine, the presser foot having a rib 47 depending from a narrow sole plate 42 and aligned with a needle aperture 46 in the latter. The presser foot is then lowered to engage rib 47 with one of the slots 30. When the machine is operated in the normal manner, the material W and the attachment are fed past the needle to form one of the lines of stitching S, rib 47 sliding in slot 30 to guide the attachment. The other line of stitching is formed in like manner by engaging rib 47 in the other slot 30.
