Title: Improvements in the manufacture and production of butanol by fermentation
IPC: C12P7/16
Filed: 1937-11-15
Abstract: Sulphite cellulose waste liquor is treated with an excess of lime, the precipitate is removed, and the liquor then brought to the desired pH value by passing the fermentation gases from the butyl fermentation of an equal amount of treated liquor through it.  The calcium carbonate thus precipitated may be separated. Entrained alcohols and acetone are thus retained in the liquors being treated. The liquor is preferably freed from furfurol and formic acid as by blowing air or steam through the hot liquor before lime treatment.

Title: Improvements in printing machines having continuously rotatable type wheels
IPC: B41J9/42
Filed: 1959-09-23
Abstract: 907,479. Typewriters &c. COMPAGNIE DES MACHINES BULL. Sept. 23, 1959 [Oct. 8, 1958], No. 32428/59. Class 100 (4). A continuously rotating type wheel printing machine has a hammer 44 for each type wheel 1 which strikes at a timed instant in the machine cycle under the action of a pre-tensioned spring 39 when a pulse applied to an electromagnet 6 releases a control member 11 which is then engaged by a toothed cylinder 5 rotating synchronously with the type wheels. A timed pulse to the electromagnet 6 attracts a blade 8 releasing it from the shoulder 13 of the member 11 which is then swung by a spring 14 first against a movable abutment 23 and then against a fixed abutment 21 from which it does not rebound. In this position a boss 19 is engaged by the next tooth of the cylinder 5 and thus swings up pivoting a member 26 to relase an arm 35 of a member 36 which under the action of the pre-tensioned spring 39 pivots clockwise causing the hammer 44 to strike. The member 36 is arrested first by a movable abutment 51 and then without rebound by a fixed abutment 55. Movement of the abutment 51 causes it to vary the magnetic field of an electromagnet 57 causing a winding 59 to send a pulse to a control circuit of the machine. After the printing cycle a re-cocking bar 61 restores the arms 35 which become re-latched by the members 26 while release of the electromagnet 6 allows the shoulders 13 of the members 11 to be re-engaged by the blades 8. The striking force of all the hammers can be adjusted simultaneously by means of an eccentric shaft 50 adjusting the position of levers 40 to which the springs 39 are attached and second levers 47 on which the levers 40 are pivoted. The position of the boss 19 relative to the toothed cylinder 5 can be adjusted by positioning a pivot screw 43 of a lever 22 mounting the abutment 21 in a slot 17. The timing of the hammer striking can be adjusted by pivoting the plate 7 mounting the electromagnet 6 and the member 11 about a screw 67. Specification 427,370 is referred to.

When making the connection by heating the hub b, the parts are assembled cold, the nut e screwed on the shaft a is tightened until the rings bear against the hub and shaft, the nut is slackened off by an angle α to allow withdrawal of the hub and is tightened again by the angle α plus an angle # giving the required increase of outer diameter of the rings and then the heated hub is again assembled on the rings and allowed to cool. The rings may bear at one end on a shoulder f on the shaft or on a conical surface, or on a combination of conical surface and shoulder. When the connection is made by cooling the shaft, the nut is screwed on the hub and presses the end ring against a shoulder f on the hub for adjustment of the inside diameter of the rings. The rings may be slotted and circlips may replace the nut e for holding the rings in adjusted position.
