Title: Improvements relating to liquid meters
IPC: G01F9/00
Filed: 1966-09-26
Abstract: 1,146,752. Measuring liquid flow. W.WIEGMANN. Sept. 26, 1966, No.42774/66. Heading G1R. In a liquid meter for determining fuel consumption in which a stop-watch is started and stopped as the liquid level in a measuring cylinder 2 falls during consumption from a first to a second calibration mark, a float 40 is provided in the cylinder 2, the stopwatch is started when the upper end of the float passes one mark and is stopped when the liquid level passes the other, the first mark being in such a position that the float is floating freely and the second in such position that the weight of the volume flow timed is constant. When floating freely the float is immersed to a depth depending on the specific gravity of the liquid, the volume of liquid surrounding the float is of constant weight and the spacing of the calibration marks is determined so that the passage of this weight is timed. In one embodiment, Fig. 6, a float 40 with guide pieces 41, 42 is inserted in the measuring cylinder 2 of the liquid meter described in Specification 940, 358 with reference to Fig. 2 thereof. When a switch is operated to light lamps 19 and open valve 10, the consumption unit draws fuel from outlet 24 and the liquid level in cylinder 2 begins to fall. A stop on a bottom extension of the float 40 holds it totally immersed at first and the presence of the float 40 prevents the upper surface of the liquid from reflecting a beam from the upper lamp 19 on to the photo-cell 20 as it passes but as the float passes a film of liquid in a cup 44 at its upper end reflects the beam and an amplified signal starts the stop-watch which is stopped when the liquid level co-operates with the lower lamp and photo-cell assembly 3a. In another embodiment, Fig. 7, a single lamp and photo-cell assembly is used. The stop-watch is started by reflection from a surface 215 held below the float 211 by spaced carriers 214 which later, when the float is left on the stops 212, do not interfere with reflection from the underside of the liquid surface when the level has fallen to the point of intersection of the optical axes 225.

Abstract: 1,118,197. Printing machines. REIDELBERGER DRUCKMASCHINEN A.G. 13 Oct., 1965 [14 Oct., 1964], No. 43474/65. Heading B6C. Apparatus for mounting and tripping the central cylinder 2 of a three-cylinder printing- press comprises two supports diametrically opposite the cylinders 1, 3 and against which the shaft at each end of the cylinder 2 is resiliently pressed and means associated with or co-operating with the supports so that operation of the means causes the cylinder 2 to be moved first out of engagement with the cylinder 1 and subsequently out of engagement with cylinder 3. As shown the cylinder 2 is the blanket cylinder of an offset printing machine but it may be a plate cylinder in which case the cylinder 1 is an inking cylinder. In one embodiment, Figs. 1, 2, the shaft ends 7 of a rubber offset-cylinder 2 are carried by bearing rings 8 supported by rollers 9, 10, 11, the rollers 9, 10 being diametrically opposite to the impression and plate cylinders 3, 1 respectively. The roller 11 is subjected to spring or hydraulic pressure 12 so as to urge the rings 8 against the rollers 9, 10 which are mounted in eccentric bearings adjustable by devices 13, 14. Two flats 15, 16, Fig. 2, are provided on the rings 8, so that if the rings are rotated by a device 17 . . . 19 from the position shown wherein the cylinder 2 is in operative position, first the flat 15 is positioned adjacent to the roller 9, so that the cylinder 2 is moved tangentially to cylinder 1 and away from cylinder 3, and subsequently the flat 16 is adjacent to roller 10 so that the cylinder 2 is moved away from cylinder 1. In one modification, Fig. 3 (not shown), the rollers 9, 10, 11 are arranged with respect to cylinder 2 in positions diametrically opposite to those illustrated in Fig. 1, and raised parts on the rings 8 then cause tripping of the cylinder 2 as the rings 8 are rotated. According to another embodiment, Fig. 4, the rings 8 are not rotatable, and the rollers 9, 10 are carried by eccentric shafts 20, 21 rotatable by linkages 22, 23 so that the cylinder 2 can be moved away from the cylinders 1, 2 by the pressure of spring-urged roller 11, and in the same sequence as described with reference to Fig. 1. As shown, the roller 11 engages the shaft 7 directly through openings 25 in the rings 8, but all three rollers 9, 10, 11 may bear directly on the shaft. The rollers 9, 10 may be replaced by adjustable wedges (Fig. 6, not shown), engaging flats on the rings 8, and a spring- pressed block may be used instead of the roller 11.

The latter is achieved by rocking a cradle 51 in which the ridge former shaft 45 is carried to lower the ridge former at every other stitch. An eccentric 24, driven at half the speed of an eccentric (21, Fig. 1 not shown) driving the ridge forming shaft 45, carries a block 25 embraced by a bifurcated end 30, 30a of a pitman 29 the other end of which is pivoted at 70 to a link 68 secured to the cradle 51 which is pivoted at 52 to the work support table 40.
