The body has a stem 1 and a boss 3, and is formed with radial slots to receive the jaws 5. The sides of the jaws may be slightly inclined and clearance may be provided at 4 so that the jaws seat firmly without rocking. A base-plate 9' rotatable on the stem 1 and a cover-plate 10 rotatable on the boss 3 enclose a ring 8 formed with cam surfaces 12 that engage the ends of the jaws and cam surfaces 13 formed on the cover-plate 9 engage under spring plungers 14 that keep the jaws seated in their slots. The parts 8, 9 and 10 are connected by bolts 11. The cam surfaces 12 are centrally recessed to facilitate manufacture and are tapered towards the axis in a direction away from the stem. Clearance is provided at 16 so that, after the jaws have been caused to grip the work, the ring 8 may be forced axially to exert a wedge grip and prevent accidental slackening back.

Filed: 1928-03-12
Abstract: 287,846. Du Pont de Nemours & Co., E. I., (Assignees of Zeisberg, F. C.). March 26, 1927, [Convention date]. Esters; alcohols; aldehydes.-The conversion of primary alcohols other than methyl alcohol, by passage of the vapours over a heated dehydrogenating catalyst is carried out under pressure whereby the formation of the ester of the acid corresponding with the alcohol is increased, an alcohol with twice the number of carbon atoms is obtained and the production of the corresponding aldehyde and acid is diminished. Temperatures of 250-500 C. and pressures of more than 10 atmospheres may be used. In treating ethyl alcohol under a pressure of about 270 atmospheres at about 350 C., about one half of the alcohol is converted into a mixture of ethyl acetate, normal butyl alcohol and a small proportion of acetaldehyde. After condensation pure hydrogen remains. The catalyst may consist of copper obtained by reduction in presence of small quantities of manganese and magnesium oxides, or of nickel cobalt or iron in admixture with other oxides such as chromium or calcium oxide, or of oxides or mixtures of oxides such as zinc, manganese chromium or manganese oxides.

Filed: 1931-03-14
Abstract: 366,323. Drying printed sheets. WOHLFELD, P. A., 11, Halberstadterstrasse, and BORSTEL, G., 6, Lutzowstrasse. both in Magdeburg, Germany. March 14, 1931, No. 7926. [Class 34 (ii).] Relates to apparatus for drying printed sheets; comprising two nests of trays A, B wherein a freshly filled tray passes step by step up nest A, being then transferred to nest B, down which it passes step by step. A sheet is fed by a belt 20 on to tapes 21 which project upwardly through the lowest tray 3, consisting of a rectangular frame with transverse wires. The tapes 21 pass round rollers 22, 24 mounted on cranks 29, 30 which are lowered to deposit the sheet on to the trav. The nest A is raised by single-turn screws 10 on spindles 9, engaging the guide rollers 5 of the lowest tray. The uppermost tray is then engaged by projections 11 on belts 12 and is carried over nest B. Nest B descends owing to the turning of spindles 15 carrying single-turn screws similar to the screws 10. The lowest tray is then engaged by projections 35 on belts 36 which move it to the right past spring catches 17, the sheet on the tray being stripped off by flexible tongues 34. In a modification, the transverse wires in the trays are replaced by chamfered projecting ribs, the trays have track rollers, and the nests are guided by front and rear vertical fillets. Chains corresponding to the belts 12, 36 for effecting the lateral movement of the trays are driven through elliptical wheels to slow up the movement of the projections at the end of the movement of the trays. The vertical movement of the trays is effected and controlled by pairs of lifting latches 59 and retaining latches 58. The latches 59 are lifted and lowered by a cam 60 and linkwork 61, 62, being swung out as necessary by a cam 68 and link work 70. The retaining latches 58 are swung out as necessary by a cam 63 and linkwork 64. A rocking gripper, or a suction cup, discharges the sheet from the bottom tray of the descending nest.

As shown, a dust cover b slidable over a cylinder a is provided with an end plug d to which the piston rod c is attached, the plug also carrying a spring cup e having wings with bosses f for pins q. The piston is as described in Specification 512,645 with a piston rod extension h passing through a partition in the cylinder. An opposing spring cup j is secured to a flanged collar i which is locked to to the cylinder a by a nut i<1>, a spring u being located between the spring cups as described in Specification 501,516. The end of the cylinder is closed by a plug k provided with two holes, the lower hole being closed by a screwed plug l and the upper hole being screwed to receive a nipple n communicating through a passage o with a reservoir p secured by a bolt r to the spring cup j.

Title: Improvements in and relating to cracking equipment for heavy liquid compounds of high distilling point
IPC: C10G9/42
Filed: 1955-03-18
Abstract: Apparatus for cracking heavy hydrocarbon materials such as mazout comprises a heated container having a horizontal base-plate divided by ribs into a plurality of longitudinal channels, and a reciprocating scraper which carries an ejector pipe, the operation being such that liquid hydrocarbon feed is discharged on to the hot base-plate as the scraper moves along the container in one direction, while the solid cracking-residue is scraped off the plate as the scraper moves in the opposite direction.  The apparatus shown (Figs. 1 and 2) comprises a preheating chamber 16 and a cracking container 20.  Hot gases from furnace 22 flow under the base plate 24 of container 20, and then pass through channels 32 into chamber 16.  The gases are finally discharged through chimney 33.  Mazout heated at 120 DEG C. is pumped through pipe 13 to U-shaped pipe 15 in chamber 16.  The preheated liquid then flows through flexible duct 17 into rigid duct 171 which <PICT:0770368/III/1> <PICT:0770368/III/2> <PICT:0770368/III/3> <PICT:0770368/III/4> <PICT:0770368/III/5> passes through a hollow stem 18 mounted in a packed gland in the end-cover 26 of container 20.  Stem 18 is attached to a scraper 34 consisting of two plates 35, 36 (Fig. 3), screwed together and defining an upper chamber 37 and a longitudinal conduit 40.  A prolongation 181 of stem 18 is attached to plate 36; stem 18 and prolongation 181 being connected by pipe 44, which passes through sealing-washer 43. Prolongation 181 supports at right angles to itself an ejector pipe 47 (Figs. 4 and 5) which has nozzles 48.  Both the free end of stem 18 and the free end of prolongation 181 are provided with pulling-plates 50 and 51 respectively, which are linked by cables to rings 54 and 55; and these in turn are connected by cables to a reversing motor (not shown).  Scraper 34 is thereby made to move back and forth in container 20.  The reversing motor which actuates scraper 34 also operates feed-pump 2.  During a back stroke of the scraper, preheated mazout flows from duct 171 through chamber 37, conduit 40 and pipe 44 into prolongation 181 and thence through pipe 47 and nozzles 48 on to the ribs 49 of base plate 24, which is at a temperature of about 600 DEG C.  The mazout flows into channels 60 where it is cracked to form vapours and coke.  The vapours are discharged through duct 30.  During the subsequent fore-stroke of the scraper the mazout-feed is inoperative, and the coke is scraped off the base-plate and transported into collector 31.  During this scraping-stroke, sufficient time elapses for the base-plate to be reheated to the cracking temperature ready for a new cycle to be started.

[Class 83 (iv)] In a swaging device of the type having radially moving swaging members acting on centria work, the said members are adjustable in length for varying diameter of work. The swaging blocks are so shaped that their lateral faces do not contact even when the work has been swaged down to its minimum diameter. As shown, wedges 18 are inserted between the two parts 8, 9 of the swages so as to vary the distance apart. The wedges have bent over ends 21 engaging in a recess in a screwed collar 22, which serves for adjusting the position of the wedges. A scale on the collar co-operates with a pointer 29 on a ring plate 11, which maintains the parts 8 in position. The parts 9 are provided with swaging jaws 14 enclosing an angle of 90‹ and said jaws are shaped to a greater curvature than the work piece. A spring ring 17, with looped parts engage pins on the parts 9 to maintain them in position. Specification 336,507, [Class 83 (iv)], is referred to.
