Title: Improvements in and relating to double-acting hydraulic shock absorbers of the piston and cylinder type
IPC: F16F9/44
Filed: 1944-07-11
Abstract: 581,467. Hydraulic shock-absorbers. GABRIEL CO. July 11, 1944, No. 13263. Convention date, Sept. 27, 1943. [Class 108 (iii)] In a double-acting piston-type hydraulic shock absorber having valves 32, 60 controlling the flow of oil past the piston 23, and to a reservoir 19 surrounding the cylinder 18 in which the piston reciprocates, means is provided for selectively regulating the spring pressure on the valves without disassembling the shock absorber. The piston 23 is mounted on a rod 15 having an eye 14 and fixed to a closed end 13, provided with a guard 11 sliding over a casing 10 forming the reservoir 19. The cylinder. 18 has a closure 16 which carries an eye 17. The valve 32 is a plate valve mounted to slide on a flanged pin 30 carried by a plug 28 screwed into the' piston head. It is pressed against the end of the piston rod by a spring 31 enclosed in a cup, the pressure of the spring being adjustable by rotation of the plug 28 on its screw thread; a spring 29 holds the plug in its adjusted position. Oil also flows past the piston by a small passage 45, and in one direction only past a cup washer 42 held between a member 43 and the piston head which is dished and has passages 40 and grooves 41 for the flow of oil. A further cup washer 33 is held in a groove under the piston head by a washer 34 and a split ring 38 having sufficient pressure to prevent the flow of oil past the washer 33 in either direction. A cup 44 prevents damage when the shock absorber is fully extended. The valve 60, which is also a plate valve, is held by a spring 59 the pressure of which is adjustable by rotation of its supporting member 57 in an annular member 48 screwed to a nut 50 mounted in the cylinder 18. The member 57 has three flats on its sides to allow the passage of oil, and the nut 50 which holds a member 52 carrying a cup washer 56 is notched on its periphery for its flow of oil. Grooves 20 are also provided in the closure member 16 for the flow of oil to the reservoir 19. In addition a small fixed orifice may by-pass the valve 60. To adjust the spring pressure of the valves from the position shown in Fig. 2, in which both valves are held seated, the piston is pushed down until arms 62 extending from the plug 28 engage a key 64 attached to the member 57 but do not engage slots 49 formed in the member 48 fixed to the casing. The piston and casing are then given relative rotation by means of the eyes 14, 17 until the load on the spring 59 is correct. The piston is then pushed down further until the arms 62 are held by the slots 49. Continued relative rotation of the piston and cylinder then adjust the pressure on the spring 31 only.

Title: Method of and apparatus for adhesively connecting the cover boards of a cover to a book
IPC: B42C11/04
Filed: 1976-04-02
Abstract: The book blocks (4) are moved, standing upright, along a guide path (1) to a pressing station at which the glued covers (6, 10) are bonded on. At the feed point (3), the book blocks are placed on the guide path in such a way that, at the pressing station (8, 12), they rest with their edge (23) opposite the back (14) against the base (20) of the guide path. The support points (20) for the lower edge (22) of the covers (6, 10) and the lower edge (23) of the book block (4) are at the same height at the pressing station. The glued cover can thus end with spacing (a) from the back (14). This prevents damage of the back binding when the book-like product is opened out. This is particularly advantageous in book-like products which are often used, such as ledgers, school notebooks and the like. <IMAGE>

Abstract: 1393856 Controlling ink and/or damping liquid in litho offset machines HEIDELBERGER DRUCKMASCHINEN AG 21 March 1973 [25 March 1972] 13580/73 Heading B6C In a sheet-fed litho offset press the ink and water on the plate are monitored by suitably filtered light rays which, upon reflection from the plate surface, are converted into electrical signals which are compared with standard values in a control box. Any deviation from the standard values causes motors driving the ductor rollers of either or both the ink and water supplies to operate and thus increase or decrease ink and/or water supplies to the plate surface. The light rays are filtered by filter discs which rotate in dependence upon the rotation of the plate cylinder, different filters being automatically swung in front of a light source as the water or inked portions of the plate surface are scanned by a head which causes signals to be transmitted to a motor driving the filter disc. Other factors such as the plate surface, the temperature and fluctuations in the light source may also be measured by light and used to control ink and water.

Abstract: 770,002. Packaging. MEDWAY PAPER SACKS, Ltd. July 29, 1955 [May 10, 1954], No. 13593/54. Class 94(1). [Also in Group XXX] Filled sacks or bags travelling on a conveyer in upright position with one side edge foremost are turned through ninety degrees about a vertical axis and then laid flat with their bottoms foremost, e.g. for delivery to a flattening and stacking mechanism, by an arm 13b pivoted on a vertical pin 11 and normally extending across the conveyer, the end of the arm having a portion 14 which is bent rearwardly to engage one face of each sack in turn over about a third of its width, so that as a sack engages the arm 13b the latter swings through ninety degrees and the portion 14 turns the sack and tips it backwards. To avoid the sack being tipped over before completing the ninety degree turn, an arm 13a integral with the arm 13b extends rearwardly parallel with the portion 14 so as to support the adjacent face of the sack during turning. A flanged portion 9 on a support 7 for the pin 11 co-operates with brackets 10 to which the arms are welded to restrict their pivotal movement to ninety degrees. A spring, (not shown) returns the arms after each sack has been tipped. The support 7 is adjustable longitudinally on a bracket 6 which in turn is adjustable vertically with respect to a bracket 1 secured to the conveyer frame 2, these parts being secured in position by clamps. Each of the arms 13a, 13b is of telescopic construction to allow of extension to suit different sizes of sacks. In an alternative construction, Figs 5 and 7, four arms 23 radiate from a hub 26a, each arm in turn being adapted to extend across the conveyer and having a rearwardly extending end portion 25. The following arm 23 acts as the support arm during turning of each sack. The movement of the arms 23 is checked at the end of each ninety degree movement by a pair of spring- loaded levers 28 carrying cam-followers 29 cooperating with a four-throw cam 27 secured to the stationary pivot 24. Alternatively a spring- loaded plunger carried by the hub may cooperate with the cam through a follower roller. The pivot 24 is movable longitudinally, laterally and vertically with respect to the conveyer by being carried on a slotted plate 20 adjustably secured to a perforated plate 18 which in turn is adjustable vertically on the bracket 1. Specification 770,001 is referred to.
