Title: Manufacture of new cellulose derivatives
IPC: C08B13/02
Filed: 1929-12-16
Abstract: Cellulose xanthates; cellulose ethers; cellulose esters and ethers, dyeing.-Alkali cellulose is treated with a mixture of carbon bisulphide and alkyl halide or aralkyl halide and the product, which shows considerable increase in weight but retains its fibrous structure, is subjected to the action of an organic base whereby a product is obtained which exhibits fundamental changes in dyeing properties: e.g. an affinity for acid dyestuffs. As examples: (a) Soda cellulose is acted upon by a solution of chloracetic ester in carbon bisulphide, and the product is treated with piperazine (or diethylethylenediamine or piperidine).  The material obtained may be dyed with acid wool dyestuff, or with insoluble dyestuffs such as those suitable for acetate silk.  (b) Soda cellulose is acted upon by allyl bromide dissolved in carbon bisulphide, and the product is treated with piperazine (or diethylethylenediamine or piperidine). The dyeing properties are similar to those in example (a).  Benzyl chloride can be used instead of allyl bromide.

[Also in Divisions A2, F4, Gl and G3] The moisture content of, e.g. cereal grain, is measured by a combined grinder and resistance or capacitance test cell. The output of the cell may be displayed on a meter or pen recorder, or operate an alarm, or automatically control a grain-dryer. In one embodiment, the grain is ground at 1, Fig. 1, and passed through a chute 4 into a cylinder 8 of electrically insulating material, e.g. nylon, where it is compressed by a reciprocating piston 10 acting against a spring-loaded valve 16. The resistance or capacitance of the compressed granulated material is measured by electrodes 14 on opposite sides of the cylinder 8 connected to an amplifier (not shown). In a second embodiment, Fig. 2 (not shown), the grain is fed by a rotating auger 19 between stationary and rotating grinding plates 21, 20, Fig. 2, which are electrically isolated and also form the measuring electrodes. The distance between the plates may be adjusted and the auger may extend into a grain drier. A thermistor is embedded in the stationary plate for temperature correction. When resistance is being measured, it is desirable for the amplifier to have a logarithmic characteristic, and two such amplifiers, one using valves the other transistors, are disclosed, Figs. 3 and 4 (not shown). For automatic control of a grain-dryer, Fig. 5 (not shown) the output of the measuring unit is compared with a preset desired value, and in an undisclosed manner stops and starts the flow of grain through the dryer.

Title: Method of reducing iron ores
IPC: C21B13/08
Filed: 1962-10-17
Abstract: Raw wood is passed together with a parallel flow of hot air through a rotary kiln where dry distillation occurs, aided by partial combustion of the volatile products.  The resultant charcoal and hot gases pass to a second rotary kiln connected to the outlet end of the first kiln, iron ore and if necessary fluxing additions also being charged to the second kiln together with more hot air for combustion of the gases. Sponge iron is withdrawn from the second kiln, while if any effluent gases remain unburnt further hot air is added.  The gases then pass through a heat exchanger where their heat is transferred to the incoming air flow.  In a modification, distillation and reduction are carried out in separate zones of the same kiln.

Abstract: 1480784 Scavenging vessels E S NETZELL 9 Sept 1974 [10 Sept 1973] 39339/74 Heading B1D [Also in Division B7]  A self-propelled or towed vessel for lifting floating oil from open water comprises a forwardly extending plate assembly 13-14a which skims the surface layer of water and oil so that the motion of the vessel carries this layer over wall 12a and onto distributing deck 15 from which it descends on to a pervious endless belt 16 which delivers the oil to a container 20, the water passing through both runs of the belt and being discharged by pumps 22. Belt 16 may be of mesh construction to retain the oil on its strands, in which case a scraper engages the belt adjacent container 20. Alternatively the belt acts solely as a conveyor and the oil is retained by a band 31, of paper or plastics, which may be perforated, or woven or non-woven plastics or glass fibres, band 31 being fed from roll 32 and discharged into container 20. Deck 15 may be perforated (Figs. 1, 3 not shown) to spread the surface layer over the upper run of belt 16, or the deck is constructed to divide the incoming layer into two streams which descend on to the belt through a central gap between the two halves of the deck (Figs 4-6 not shown). The rollers 17, 18 and a support grating comprising parallel bars or corrugated sheets below the upper run of the belt (Fig. 3 not shown) form the belt into a dished section to receive the liquid. The lower run of the belt may be similarly formed so that it will retain oil which has penetrated the upper run. The vessel is of catamaran construction with separate container 20 enclosed by stern pontoons but floating freely. Skimming plate assembly 13-14 g is adjustable to a raised position when not in use. Various baffles 30, 35 ensure that pumps 22 are always under water (level 23) and reduce the effect of waves in the water flowing onto deck 15.

Abstract: 344,573. Projectiles ; fuzes. PEREGO, L., 27, Via Ariosto, Milan, Italy. Dec. 24, 1929, No. 39479. [Class 9 (i).] Relates fuzes of the kind comprising two members 4, 41 kept apart by a spring 5 against concave seats so arranged that impact in any direction causes the parts 4, 41 to approach each other whereupon a percussion cap 15 in one member is fixed by a striker 14 on the other. According to the invention, the members 4, 41 take their seat in recessed parts 6, 6<1>, one at least of which is shaped as to ensure the disengagement of the members 4, 41 from their seats under the action of any shock, with the result that if the first shock has failed to fire the fuze the fuze is disarmed and made safe for subsequent handling. This action is obtained by making the edge of the seat oblique in direction with various profiles, or by arranging the axes of the seats out of alignment. Before use, the members 6, 6<1> are kept apart by a forked safety device 8 attached to a plug 7, which forms one side of the chamber containing the members 6, 61. This chamber may be in the middle of the bomb as in Fig. 1, or at one end of the bomb as in Fig. 4, which also shows a lid 10 secured by a split pin 11 for holding the plug 7 in place, the pin 11 being provided with a ring 12 to facilitate its removal before the bomb is thrown.
