IPC: E21C31/02
Filed: 1923-11-08
Abstract: 225,689. Thomson, W. Nov. 8, 1923. Coal-cutting machines.-In machines of the chain, bar, or disc type and in which the cutting element is operable at different levels, the cutting element is adapted to be revolved about a fixed axis and also about an axis spaced from the fixed axis and revoluble thereabout. The cutterchain machine shown, which may run on rails, comprises a gear head in two parts C. D, a jib. bracket U, and a cutter-chain drive sprocket S which is driven from the motor shaft B through gears L, M, a driven shaft N, bevel gears O, P, and an operating shaft R. The jib )racket U is slewed by means of the ring V having a bearing on a member W on the part C and having a toothed rim for engagement with a slewing pinion Y. The part C can rotate about the shaft N by means of a flange H mounted in the part D, the flange carrying a boss T and worm wheel which engages a worm K. The gear case as a whole can rotate about the shaft B by means of a flange E on the part D engaging the machine casing, the flange E being also provided with a boss F and worm wheel which engages a worm G. The jib can thus rotate about shaft R, the jib and the part C can rotate about the shaft N. or the entire gear case and jib can rotate about the shaft B, so that the jib, whencarrying either a cutter chain or cutter disc can operate parallel to, or at any angle to, or at any height from, the ground. The worms G, K and pinion Y may be hand or mechanically actuated. and a haulage gear may be fitted at the back of the machine. When a cutter-bar is used, the bar is arranged to operate with its axis coincident with the drive shaft or with its axis passing through any points on the circumferences of circles described about the axis of the drive shaft and having radii equal to or less than the dis tance between the last-mentioned axis and that of the bar when in its furthermost out position from the drive shaft.

Title: Method for producing ª‡-keto glutaric acid by fermentation
IPC: C12P7/50
Filed: 1965-07-02
Abstract: a -Keto glutaric acid is produced by the aerobic culturing of a microorganism of a strain capable of producing a -keto glutaric acid in a nutrient medium containing a C10- 25 n-paraffin or a C10- 25 n-paraffin-containing petroleum fraction, the medium being stirred and its pH being maintained at 5-8, accumulating a -keto glutaric acid in the medium and separating the acid so produced.  Preferred strains are those of the genera Corynebacterium, Brevibacterium, Anthrobacter and Micrococcus. The nutrient medium may also include a source of nitrogen, e.g. ammonium salts or urea, and organic nutrients, e.g. peptones, corn steep liquors, meat extracts, hydrolysates of soybean meals, yeast extracts, amino acids, organic nucleic bases, and vitamins, e.g. thiamine.  It is preferred to include calcium carbonate in the nutrient medium.  In examples, dodecane, C12- 14 and C11- 19 n-paraffin mixtures and kerosene are used as the carbon source.
Patent GB-740735-A (GB)
Title: Improvements in apparatus for moulding tablets of plastic material
Inventor: BROOK LEONARD
IPC: A23G3/02
Filed: 1953-10-14
Abstract: 740,735. Tablet-moulding machines. FORGROVE MACHINERY CO., Ltd. Aug. 9, 1954 [Oct. 14, 1953], No. 28318/53. Class 87 (2). A machine comprising a rotary die head for moulding a rope of plastic material, e.g. candy, into a string of tablets, a conveyer below the die head having pockets shaped to carry the tablets in the string and driven synchronously with the die head and a guide for guiding the string of tablets from the die head to the conveyer is provided with means operable, without other than a momentary interruption of synchronous running of the die head and chain, to free the string from support by the guide so that the string thereafter remains freely suspended between the die head and the chain. A rope 17 of sweet stuff is fed to a rotary moulding wheel 11 and moulded into a string 19 of tablets connected by their webs of stock, the string being initially directed by a guide 26 so that the tablets enter pockets 25 in a conveyer 24 which is driven synchronously with the moulding wheel. The tablets are moulded by the co-operation of flaps 13 with moulding cavities 10, cams 15 and 18 causing the flaps to move to and from-the cavities. The string is freed from support by the guide either by retracting the guide or by momentarily altering the relative speeds of the moulding wheel and conveyer, the latter method being preferred as the movement of the guide can then be reserved for the operation of a trip mechanism. By the first method the guide is mounted on one end of a bell crank arm, the other arm of which is manually operated by a lever to move the bell crank so as to retract the guide. By the second method a helical gear wheel 21, through which the drive is transmitted from a shaft 14 to the moulding wheel, is shifted axially along splines on the shaft 27 and there, owing to the helix angle on the teeth, superimposes a slight anti-clockwise rotation on the moulding wheel, the movement of the conveyer 24 being unchecked and the string of tablets being tautened and lifted off the guide. The gear wheel 21 is shifted by a fork 29 when a lever 35 is moved. This lever is held in its two extreme positions by a projection 36 from it which enters one of two notches in the bush carrying its spindle 31. To free the lever it is swung anti-clockwise, as seen in Fig. 3, against a spring 38. The arrangement may be inverted by shifting the helical gear in a direction to give momentary acceleration to the gear wheel 20 which drives the conveyer 24. Specifications 406,220 and 640,440, [Group XXVIII). are referred to.

Title: Improvements in or relating to the cleaning of drums, barrels or the like
IPC: B08B9/08
Filed: 1939-10-25
Abstract: 535,976. Cleaning drums, barrels &c. WALDE, R. S., and BLAGDEN & CO., Ltd., V. Oct. 25, 1939, No. 28651. [Class 21] Drums, barrels or like containers are cleaned externally by floating them on the surface of a detergent liquid and rotating them while they are so floating, their buoyancy holding them against brushing devices applied to their upper surfaces. The liquid is contained in a rectangular tank 11, the removable cover 23 of which carries rollers 24, 25 for rotating a drum &c. and a rotatable cleaning brush 37. The rollers 24, 25 are rotated by a motor mounted upon the outside of the cover and are grooved longitudinally to receive india rubber driving slats 28. The cover 23 is movable vertically between upright guides 44 and is connected to pistons operating in air cylinders at opposite sides of the tank. Hand-operated cocks are provided for admitting and exhausting the air to and from the cylinders for raising and lowering the cover. Raising of the cover actuates a discharge cradle 71 to lift the cleaned drum 12 from the tank on to a runway 16 leading to a washing trough. Interconnected with the cradle 71, but actuated also by the raising of the cover 23, is a loading cradle 81 so shaped that when the cradle is lifted a part 83 prevents a second drum from moving off its runway 14. The timing of the movements of the cradles 71, 81 is such that the cradle 81 is not actuated until the cradle 71 has removed the cleaned drum and has returned to a position to receive another drum and lower it gently into the liquid. A grid of steam pipes 18 serves to heat the detergent liquid and forms with a false bottom 20 a zone for the dirt. To remove the collected dirt, the liquid is drained through a drain cock and the false bottom is slid through an opening normally covered by a door 21.
