Title: Process for Recovering a Hydrocarbon from a Hydrocarbon Fermentation Liquor.
IPC: C12P21/00
Filed: 1968-07-18
Abstract: 1,176,110. Recovering hydrocarbon from fermentation liquor. KYOWA HAKKO KOGYO CO. Ltd. July 18, 1968 [July 22, 1967], No.34365/68. Heading C6F. Carbon source hydrocarbon is recovered, at the completion of fermentation, from a fermentation liquor obtained by culturing a hydrocarbonassimilating micro-organism under aerobic conditions in an aqueous nutrient medium containing at least one hydrocarbon (specified) as the main carbon source, by adding a hexane (n-hexane or isomers thereof) to the fermentation liquor, a concentrate of the fermentation liquor or a mixture of the hydrocarbon and the micro-organism, preferably in a proportion of at least 10% by volume, and then freezing the resultant mixture to separate the water therein. The filtrate is distilled to separate the hexane and to recover the hydrocarbon. The liquor may be taken to -10‹C. or - 20‹C. for 2 or 5 hours to freeze out the water.

IPC: C01D7/00
Filed: 1932-02-19
Abstract: Potash salts are recovered from the dusts collected from the flues of hot air stoves, blast furnaces, &c. by treating the dusts with water, removing the precipitated dust and evaporating the solutions obtained by the waste heat of the flue gases.  The solutions may be concentrated by evaporation in flat iron pans which can be slid or inserted on top of the flues or the hot gases can be drawn off through pipes and passed directly into the solution.  The precipitated dust may be used for paint as described in Specification 345,987.

Abstract: 1,057,852. Making electrodes; bending; welding by fusion. HARNISCHFEGER CORPORATION. Aug. 30, 1963 [Oct. 12,1962], No. 34458/63. Headings B3A, B3E and B3R; An arc welding electrode is made by closing a strip to a channel section extruding a flux core into the channel section at a rate which varies with the velocity of the strip; and closing the channel section about the flux core. The strip is pulled by feed rolls 9, one of which is rubber surfaced, from a reel 1 and passes through driven forming rolls 10, 11 which form it into a channel section. The section is guided under a volumetrically controlled extrusion press which extrudes a core of flux into the section which is closed by two pairs of idler rolls 16, 17 on vertical axes and two pairs of driven rolls 18, 19 on horizontal axes. If desired the strip edges are welded by a high-frequency resistance welding unit 20 before being coiled on a driven drum 6. The hydraulic motor driving the drum 6 and the hydraulic motor driving the rolls 9, 10, 11, 18, 19 are so adjusted that the strip is under tension. A wax lubricant, may be applied to the under, surface of the strip 2 before it is fed to the forming rolls. In a modification the channel section is closed by a fixed die located adjacent the extruding point. The electrode may be of low hydrogen type and be baked after coiling. The flux may include alloys, sodium alginate and potassium silicate.

In an alternative embodiment, Fig. 3, the knives 11, 12 may be used for slitting as in the Fig. 1 embodiment or the yokes may be moved outwardly to position the knives for trimming the plates. A cross-cut scrap shear 19, 20 is mounted downstream of each longitudinal knife pair, to cut up the trimmed strips 33. There may be synchronization circuits between driving motors of the longitudinal and cross cut top knives or, as shown, a drive shaft 16 for the knife 12 is coupled to a drive shaft 24 for the knife 20, via a gear (26) and a clutch plate (28), Fig. 4, not shown.

Abstract: 972,031. Bottle unpacking machines. HOL. STEIN & KAPPERT MACHINENFABRIK PHOENIX G.m.b.H. Sept. 12, 1962, No. 34787/62. Heading B8C. A machine for unpacking bottles from crates has grippers 3 assembled on a head 4, which is actuated by an hydraulic mechanism 5 consisting of two pistons 6 and 7. When the grippers engage the bottles in a crate both pistons are at their lowest positions. Piston 6 is then caused to rise by means of oil entering in the bore 8 through connection 12 until it abuts against the rod 11 of the piston 7. The oil pressure above the piston 7 is equal to that below the piston 6, but due to the different effective areas the upward rise of the piston 6 is checked. The bottles are then moved so that they are a small height relative to the height of the bottles above a conveyer belt 2 and are dropped. The piston 7 is then permitted to rise, piston 6 rising with it in order that the grippers should clear the mouths of the bottles.

The tool heads may be multi-spindle heads and perform drilling, boring, milling or screw threading operations. A computer control device identifies through reading means 83, 84, the required tool head. Tool head conveying and securing.-The track comprises a pair of chains (31), (32) (Figs. 10 and 11, not shown) having upper friction driving plates which engage the underside of the tool heads. When a tool head is stopped in advance of a machining station by an escapement bar 87, the friction drive slips as the chains are continuously driven. The escapement bar 87 is rotatable to release tool heads from abutments 96, 97 to allow a shuttle bar 86 to feed a tool head to the machining station. At the machining station a tool head is located by pins 74, 75 engaging recesses 82, and is secured by clamps 76, 77. In an alternative embodiment (Fig. 19) the tool head is located and secured by a wedge 209 being laterally forced against a cam 213 to force the tool head downwards and sideways against opposed abutments 217 and a spring return plunger 223. In this embodiment also, when the tool head is secured the chain drive is lowered out of contact therewith by a mechanism 309, 312, 213. Workpiece supporting.-The workpiece supporting means 106 comprises a laterally driven slide supporting an indexable table 113. On the table is a work support 124 having locating means 131, 132 and clamping means 128. A switch 133 provides a control signal indicating the presence of a workpiece.
