Abstract: 1311607 Damping apparatus in printing apparatus ROLAND OFFSETMASCHINENFABRIK FABER & SCHLEICHER AG 19 April 1971 5 March 1970] 23065/71 Heading B6C A plate cylinder 6, Fig. 1, is dampened by a roller train comprising a formation roller 5, an intermediate roller 4, a distributing roller 3 and a forme roller 1 the fountain and dietributing rollers being on fixed axes whilst the intermediate and forme rollers are mounted on bearings the whole train being in continuous contact during operation. The bearings 10 carrying the forme roller 1 are movable through hand operated cam device 20 to firstly move the roller from the plate cylinder and subsequently to withdraw the roller so that it also does not contact the distributing roller 3. A similar mechanism including cam device 43 enables the intermediate roller 4 to be initially withdrawn from the roller 3 and subsequently from the fountain roller 5. The latter is driven by a variable speed motor 20 and provision is also made to enable finite adjustment of the rollers 1 and 4 relative to the other rollers and the plate cylinder. Fig. 5 shows an arrangement of fountain, intermediate distributer and forme rollers 56, 55, 52 and 50 wherein movement of rollers 50 and 55 is effected through the use of pneumatic means. In a further arrangement the damping apparatus is operated automatically.

Abstract: 461,567. Crockery &c. racks. SMITH, S., (trading as SMITH BROS.). Aug. 19, 1935, No. 23205. [Class 28 (ii)] The body 10 of the rack of generally rectangular configuration is built up of a pair of frames 11 of wire or strip metal bent into substantially U-form and connected together by three horizontal frames 12, 13, 14, of open rectangular configuration which are welded to the frames 11 at the corners. The upper frame 14 is arranged below the level of the upper ends 15 of the frames 11, spaced horizontal rails 20 extending round the projecting portion of these ends to form a tray 19, the base of which is constituted by a length of open wire mesh extending across the frame 14 and down the rear of the rack. In a modification, the tray is formed by a piece of wire mesh attached to the upper rail 20 and bent into the form of an open tray, the middle rail 20 being dispensed with. The end frames of the rack body are closed partially by wire or strip metal members 16 extending diagonally between the corners of adjacent horizontal frames, these members being secured together by welding. To support and separate plates in the rack, a pair of grids 28 constructed separately from the body of the rack and each comprising three horizontal bars 29, 30, 31 spaced apart by a distance corresponding to the distance between the horizontal frames of the body and connected by a number of spaced vertical division members 32 of wire or strip metal welded to the bars are mounted in the rack after the body portion has been assembled and are secured in position by welding the projecting ends of the bars to the end portions of the corresponding horizontal frames. For collecting drained liquid a shallow metal frame 21 is supported beneath the lowest frame of the rack by a pair of supporting members 22 extending transversely of the rack, the front end of each wire being bent outwardly and downwardly and welded to the front limb of the adjacent end frame, the rear end being bent upwardly and round the adjacent part 25 of the lower horizontal frame. The tray is prevented from moving transversely by bent up portions 26 of extensions of the end frames, these extensions forming feet 27.

As shown in Fig 7, the sheath surface 26' is longitudinally scored or milled with grooves 27. In another form (Fig. 8 not shown), the roller has no sheath and the solid body of the roller hasgrooves cut in its surface as in Fig. 7. To prevent ribbed rollers from interlocking with each other they may be provided integrally or separately with annular smoothsurfaced bands (Fig. 14 not shown). These bands may also be provided on sheathed rollers.

Abstract: 1461270 Analysing slurries NATIONAL RESEARCH DEVELOPMENT CORP 22 April 1974 [16 May 1973] 23300/73 Heading G1A In a device for analyzing flowable slurries 2 such as from a constant head tank 3 wherein the slurry is caused to flow over a flat or slightly curved surface 1 at a predetermined thickness by a splash guard 5, the slurry is investigated by an analytical technique 6 using either x-ray fluorescence, infrared reflectance or emission spectrography. The x-ray technique may involve reflecting x-rays off the surface 1 after passing through the slurry, or, the surface 1 may be made of x-ray transmissive material, or, the surface may be of the sort of material which fluoresces under x-rays and the resultant attenuated fluorescent radiation can be measured. The surface 1 may be made of electrical conductive material with a high voltage electrode 14 Fig. 3, (not shown), positioned over the surface. The resultant discharge passes through the film of the slurry and a fraction of the film disturbed by the discharge would be excited and emit characteristic radiation which can be investigated by optical gratings with associated slits and photo-multipliers. The photo-multipliers may supply a computer interface or a cathode ray tube. In the infrared reflectance arrangement for measuring the amount of water in ethanol, the - detector may have a pair of filter associated with it, the filters being mounted so that they can be rotated successively past the detector.

Abstract: 532,072. Regulating. BOSCH GES., R. Aug. 16, 1939, No. 23592. Convention date, Aug. 16, 1938. [Class 7 (vi)] The control rod 2 of the fuel pump 1 is fitted with a collar 6 adapted to engage a stop 47 which is adjusted through a servomotor 43 in accordance with induction pipe pressure acting on a capsule 36, and temperature acting on a thermostat 58, and with atmospheric pressure acting on a capsule 62. The capsule 36 adjusts the servomotor through a lever 38 pivoted at 39 and a bell crank 41, the free end 48 of which slides-in the forked arm 49 of a lever 50 moved by the thermostat, the arrangement being such that equal changes of induction-pipe pressure cause displacements of the stop 47 ,which increases progressively with reduction of the temperature. The pivot 51 of the lever 50 is carried eccentrically on a disc 60 connected to the capsule 62, so that decrease in atmospheric pressure increases the supply of fuel. The control rod 2 of the fuel pump is connected to a spring-pressed diaphragm 14, the righthand side of which is connected directly to the induction pipe by a valve 16 when the operating hand-lever 10 is in the stopping position A or idling position B, but is cut off from the induction pipe when the lever 10 is in the full-load position C or starting position D, the lever 10 being connected to the valve 16 by a rod 9, lever 7, and rod 15. The lever 7 also acts as an abutment to control the movement of the collar 6 independently of the stop 47. Air supplied by a supercharger 25 is controlled by throttles 26, 27, the former being adjusted by an arm 71 and bellows 65 subjected to the induction-pipe pressure, and the latter being opened by an arm 29 and a stop 32 on the rod 9 in positions between idling and full load. At starting, the throttle 26 is fully opened by another stop 68 on the rod 9, and extra fuel is supplied by means of a button 72 which through links 73, 74, 75 extends the rod 2 to the left against the action of a spring 4. In a modification, the valve 16 is omitted, and the stop coacting with the collar 6 is controlled directly by a piston subjected at one side to inductionpipe pressure and at the other side to atmospheric pressure.
