Title: Improvements in or relating to the manufacture of 5-nitro-furan derivatives
Inventor: GREENSMITH DENIS ERIC
IPC: C07D307/76
Filed: 1956-01-03
Abstract: 5-Nitro-2-furfuraldehyde semicarbazone is prepared by heating a reaction mixture containing 5-nitro-2-furfuraldehyde and semicarbazide, said semicarbazide being contained in a reaction solution resulting directly from the interaction of urea and hydrazine in aqueous solution.  A strong acid is preferably present especially sulphuric or hydrochloric, although phosphoric or trichloracetic acids may be used.  The 5-nitro-2-furfuraldehyde may be prepared in situ, preferably before admixture with the semicarbazide solution, by hydrolysis of 5-nitro-2-furfuraldehyde diacetate by heating with an acid, preferably a strong mineral acid, especially sulphuric.  It is also preferred to have present in the reaction mixture an inert water-miscible solvent, such as ethanol, preferably in an amount sufficient to produce a homogenous initial reaction mixture.  The product may be purified by washing with a hot solvent, e.g. ethanol, capable of dissolving 5-nitro-2-furfuraldehyde or the diacetate thereof.

Abstract: 110,994. Hunter, S., and Simon-Carves, Ltd. Jan. 8, 1917. Addition to 22189/13. Filtering-plant.-Washed material from a coal and like washing apparatus is delivered along a trough a to the primary inclined sieve b, through which the slimes and most of the washing water pass through a casing h into a settling tank c. The shaking sieve d, instead of being arranged above the primary sieve, as described in the parent Specification, is arranged below and receives the washed material from the primary sieve. From the shaking sieve the washed material passes into a tank g. The slimes from the sieves b and d are conducted by a pipe from the tank c to the trough a or to a fine sieve f delivering to the sieve d, or directly to the sieve b or the sieve d.

Title: Hat brim pouncing machine
IPC: A42C1/06
Filed: 1943-01-15
Abstract: 565,178. Hats. HEIDE, H. C. (Doran Bros., Inc.). Jan. 15, 1943, No. 778. [Class 63] In a machine for finishing, e.g. pouncing, the brims of hat bodies, the hat 33, Fig. 2, is supported mainly on a flat table 135a while a pair of tools engage the upper and lower surfaces of the brim. The tools move in closed paths at high speed and the hat is fed by a driven circular member 123 of resilient material and smaller than the hat crown both heightwise and transversely, urged toward the inside face of the crown, which is backed by a member 144, the lower edge of which is adjacent to the operative faces of the tools. Sand-paper is fed over the faces of the tools as they are separated for work changing. The machine is driven by an electric motor 62 connected by rubber belts 73, 77 to a shaft 22 rotated at about 3,600 revolutions per minute. Eccentric portions of the shaft actuate the upper tool holder 41 and the lower tool holder 51, each holder being guided by a shaft 44, 54 respectively, sliding in a tube swinging about an axis 48. The upper tool is fixed heightwise of the shaft 22 by its ball-bearings, but the lower tool is depressed for work-changing being slidable on a sleeve 56. A handle 87, Fig. 3, is geared to a link 95 actuating a yoke 98 pivoted at 102 which depresses the tool against the action of a spring 83, Fig. 2. The feed member 123 is driven at some 17 revolutions per minute from the motor by gearing comprising belting and a pair of worms and worm-wheels in series. The table 135a is adjustable about a pivot 138, and the whole work support can be swung about a pivot 131 for work-changing after the lower tool has been depressed. At each depression of the lower tool the sand-paper strip 185 on each of the tools is fed by ratchet-wheels 243, 244, Fig. 3. The upper wheel is actuated by a pawl 245, on a pivoted arm linked to the yoke 98. The lower wheel is actuated by a pawl 261, the pivot of which is fixed heightwise. The strip passes between a roller 190, Fig. 6, and a wear-plate 195, the pressure of which is adjustable by a thumb-wheel 198. From this roll the strip passes over an arc-shaped plate 186 to the operative face of the tool, a rubber backing 180 being provided, round a roll 201 and to the grip of toothed drums 204, 205 driven by the pawl-and-ratchet mechanism. The depth of mesh of the teeth is adjustable by a screw 211. Most of the mechanism is covered by a casing in two halves 271, 272, Fig. 5, held together by hooks 287a, 288a on levers pivoted to a plate 282 engaging pins 279, 280 on the two parts of the casing and urged to operative position by springs 289, 290. The other ends of the levers are engaged by a spring plunger 294 having a head 296 accessible through a hole in the casing.
