Title: Improvements in the manufacture and production of organic compounds containing oxygen
IPC: C07C29/151
Filed: 1925-10-19
Abstract: 266,405. Johnson, J. Y., (Badische Anilin & Soda Fabrik). Oct. 19, 1925. Methanol; oxygenated organic compounds. - In the production of methanol and other oxygenated organic compounds by the catalytic hydrogenation of carbon oxides at elevated temperature and pressure, mixtures containing a high percentage of inert gases are employed, and the operation is conducted in a circulatory system with a continuous removal of part of the circulating mixture enriched in inert gases and its replacement by fresh gas mixture in such proportions as to maintain a constant composition of the circulating mixture. Instead of using inert gases, mixtures containing a large excess of one of the reaction gases may be employed, the excess then functioning as an inert diluent. According to the example, power gas is first passed with steam over iron oxide to produce, after removal of the carbon dioxide formed, a gas containing carbon monoxide and hydrogen in the proportion of 1:2, together with a large percentage of nitrogen; the mixture is circulated under pressure over a methanol forming catalyst; residual gas is continuously withdrawn and replaced by fresh gas in a certain proportion so as to maintain the composition of the circulating gas constant at a given percentage of reaction gases. Specification 229,714 is referred to.

Title: Improvements in and relating to dynamo-electric machines
IPC: H02K23/20
Filed: 1919-11-11
Abstract: 158,821. White, A. E., (U.S. Light & Heat Corporation). Nov. 11, 1919. Exciting; rotary converters.-A single-armature continuous-current machine which can act as a motor-generator or a double-current self-regulating generator has main dissimilar pole pairs for producing the main field and intermediate pole pairs of similar polarity for modifying the main field so that in one half of the armature the flux distribution is that of an n-pole machine and in the other half it is that of a 2 n-pole machine. The armature coils have a span of 120 electrical degrees with respect to the main pole pairs. In the form shown in Fig. 5, the two main poles 9, 10 and the modifying poles 11, 12 are excited by shunt coils 13, 14 connected between the brushes 5, 6 through adjustable resistances 13<1>, 14<1>. The modifying poles also have coils 15 ccnnected at one end 16<1> through the arc-welding or other load circuit 16 to the brush 5 and at the other ends to brushes 7, 8 which are displaced by 60 electrical degrees from the brush 6. The poles 11, 12 are given similar polarity by the coils 14, as shown in Fig. 2, and this is overcome and eventually reversed, as shown in Fig. 3, bv the increasing load current in the coils 15. The volts between the brushes 5, 6 are thus maintained to give a stiff main field while the load volts fall considerably. In' a continuous-current converter, Fig. 11, the main poles 9, 10 are shunt-excited by coils 13 between one supply main 17 and one side of the work circuit 16, while the modifying poles 11, 12 receive similar polarity from coils 14 shunted across the supply mains 17, 18 through a resistance 19. The modifying poles also have coils 15 connected between intermediate brushes' 7, 8 and a common point in the work circuit. As the load current increases, the coils 15 reduce or reverse the polarity due to the coils 14 so that the load volts fall while those on the brushes 5, 6, and therefore the speed of the machine, are substantially constant. Fig. 14 shows a system in which, by means of a switch 19, a self-regulating machine of the above described type is connected to a load 16 and a battery 20, direct connection of the load and battery being effected by a manually or automatically-operated switch 17. Coils 13, 14 shunted across the brushes 5, 6 through regulating resistances 13<1>, 14<1> excite the main and modifying poles 9, 10 and 11, 12 with dissimilar and similar polarities respectively, and the modifying poles also have coils 15 connected in series with the load between a common point 7<1> and brushes 7, 8 which are displaced by about 60 electrical degrees from the brush 6. With no load current, a two-pole main field exists, but when a load current flows the field is modified bv the poles 11, 12 so that at heavy loads the battery assists the generator, the armature cross-flux being also compensated at all values.

Abstract: 1,121,608. Sewing machines. JANOME SEWING MACHINE CO. Ltd. 8 June, 1967 [9 June, 1966; 11 July, 1966], No. 26599/67. Heading D1G. A lock stitch sewing machine is converted to chain stitching by providing a loop retainer which rotates co-axially with the rotary lock stitch looptaker, the arrangement being such that the thread loop expanded by the looptaker is held in expanded condition by the loop retainer, the needle in its next descent passes through the expanded loop to form a fresh loop, and the expanded loop is shed from the retainer to engage the fresh loop for forming a chain stitch. The rotary looptaker 1, having a loop-seizing beak 4, journals a bobbin carrier having a central pin 7. The loop-retainer 6 has a hub 16 bored to receive pin 7 and secured thereto by a grub screw 23. Rigid with hub 16 is a diametrically-disposed web 17, from the opposite ends of which extend helicallyshaped fingers 9 and 10 respectively. Finger 10 ends with an axially-disposed thread-engaging edge 18. Finger 9 and edge 18 extend within the outer end surface of looptaker 4. Thread-retaining notches 19 are formed at the ends of web 17 at the junctions of fingers 9 and 10 therewith. Boss 16 is secured to looptaker 1 by a tongue and groove connection (not shown), with web 17 disposed substantially at right angles to the diametrical line through beak 4 and with finger 10 disposed on the side of web 17 away from beak 4. In operation, an initial thread loop Ro, seized by beak 4 from the needle 2 and expanded over the looptaker body, is guided by the fingers 9, 10, after the loop has been cast off by beak 4, into engagement with the notches 19. The needle on its next descent to seize a fresh loop Rn, passes into the expanded loop Ro, and the latter, on further rotation of the looptaker, is shed from the loop-retainer 6 and is tightened by the take-up 57 upon loop Rn. Expansion of a loop by the loop-retainer 6 serves to draw thread from and thereby tighten the previously formed stitch. A thread-guiding pin 59 is positioned adjacent take-up 57 to restrict the supply of thread thereto, and the thread tension, as set by the tensioner 56, is increased over that required for lock stitching. The looptaker and thread-retainer may form an integral unit.
