Abstract: 390,030. Packeting cigarettes. UNIVERSELLE CIGARETTENMASCHINENFABRIK J. C. MœLLER & CO., 48, Zwickauerstrasse, Dresden, Germany. June 25, 1932, No. 18003. Convention date, July 7, 1931. [Class 94 (i).] In cigarette-packeting machines, undesirable movement of the cigarettes is checked by causing them to adhere more closely to the guide surfaces over which they are moved. As shown, the bottom layer of the cigarettes b in a hopper a is thrust into guide troughs d by a plunger c, and are then engaged by pushers g on chains e and moved into a packet i on a track h. The guide troughs d, which may be shaped so as to cause cigarettes of oval cross section to move gradually into overlapping relation are provided with orifices m leading to a suction chamber r, to cause the cigarettes to occupy their correct positions in the troughs and to remain in contact with the members g. In a modification, downwardly directed blasts of air are used to hold the cigarettes on the guide troughs. The Specification as open to inspection under Sect. 91 comprises also the use of springs engaging over the cigarettes. This subjectmatter does not appear in the Specification as accepted.

The Fe compound may be FeCO 3 , and oxidation effected by blowing in air. Preferably only part of the solution is treated with the Fe or Fe compound, and is recombined with the untreated part before oxidation. Absorption may be effected in one or several spray towers. When the concentration of the circulating solution reaches saturation, part of it is drawn off (as FeSO 4  or Fe 2 (SO 4 ) 3 ) and replaced by water. The concentrated solution is sprayed into the gas to be purified which is at 130-180 C. to effect partial dehydration, and the solids may then be heated at 650-750 C. to form Fe oxide and SO 2 .

IPC: F23L17/16
Filed: 1959-05-27
Abstract: 866,252. Blast apparatus for locomotives. NIKEX NEHEZIPARI KULKERESKEDELMI VALLALAT. May 27,1959 [May 29, 1958 No. 18114/59. Class 51 (1). A star-shaped blast nozzle 1 for a steam locomotive smoke-box is positioned below a chimney having a cylindrical mixing part surmounted by an outwardly flaring conical discharge part. The discharge end of the nozzle 1 is less than ¥ of the smallest diameter D1 of the chimney below a point at which the diameter of the bell mouth of the chimney is 1.2 D1. The outer surface of the blast nozzle 1 is also of star-shaped cross-section so that the exhaust gases flow inwardly towards the axis of the cylindrical mixing section of the chimney, and the branches of the nozzle may be twisted, Fig. 7, to give a helical motion to the blast and gases to improve the mixing. The blast nozzle 1 is fed from a receiver 11, into which flared diffusers 12 lead the exhaust steam so that the back pressure is reduced. In order to obtain the benefit from the blast nozzle the liner of steam chest slide valve is modified so that the effective inlet cross-section is less at the beginning of the steam inlet stroke, than over the main part of the stroke, and the discharge ports have a smaller cross-section over the starting part of the outlet stroke than over the remainder.

Abstract: 669,022. Electric discharge lamps. GENERAL ELECTRIC CO., Ltd., NELSON, E. H., and POWER, E. B. June 26, 1946 [July 16, 1945], No. 18136/45. Class 39 (i). A high-pressure metal vapour electric discharge lamp of the type in which the envelope is made of quartz and in which the distance between the electrodes is small compared with the internal length of the envelope in at least one direction, has a protected region, i.e. a region of the lamp which is protected against the arc flare either by an appreciable space between the arc and the envelope.or.by the provision of a shield between the envelope and the arc, and is combined with means for generating between magnetic pole-forming elements fixed relatively to the lamp envelope a magnetic field so as to tend to increase the length of the flare towards the protected region and so that if the lamp is rotated the flare rotates in the same direction and remains directed towards some part of the protected region. In the construction shown in Figs. 3 and 4 the envelope 11 is cylindrical and the arc path is perpendicular to the axis 16 of the cylinder and away from the centre of that axis and the electromagnet 15 in series with the lamp generates a magnetic field perpendicular to the arc path and to the axis 16 so that during rotation of the lamp and the magnet 15 the flare 14 remains directed substantially towards that end of the envelope which is further from the arc path. In the construction shown in Fig. 5 the envelope is spherical and the arc path is displaced from the centre of the sphere, and in the construction shown in Fig. 6 the envelope is spherical, the arc path is central or off-centre and a shield 19 which may be of metal and part-spherical is provided.

Title: Improvements in internal combustion engines
IPC: F01L1/12
Filed: 1918-11-06
Abstract: 142,520. Bamford, J., and Bamford, C. J. Nov. 6, 1918. Valve-gear.-Exhaust and inlet valves 1, 3 are arranged in the positions shown without forming pockets in the combustion chamber, and the exhaust valve or both valves are worked from a halfspeed cam or crank 23 and a reciprocating rod 20 carried in guides 21, 22. This rod is in line with the inlet-valve casing 7<a> and is cranked or looped to clear it, and additional guides for the valve-rod may be formed on the casing 7<a>. In the arrange. ment shown, the inlet-valve 3 is automatic, but it may be worked by levers actuated by an inclined surface on the valve-rod 20. Regulating.-A centrifugal governor on the crank-shaft adjusts a lever 36 so as to bring a catch-piece 38 beneath a catch 39 and hold open the exhaust valve when the speed is excessive. A leaf spring may be provided on the rod 20 to engage the collar on the inlet-valve stem and hold the inlet valve closed when the exhaust valve is open. The speed of the engine is regulated by adjusting the set-screw 40 in the lever 36 so as to vary the effective load exerted on the governor by the spring 41 against which the set-screw bears. In a modification, Fig. 5, suitable for heavy fuel, the governor controls a throttle valve 44 in the inlet pipe by means of a light rod 53 passing through the bed-plate and lever arms 52, 48 at the bottom and top respectively of a vertical spindle 49, the arm 48 being moved by the governor sleeve 34. The speed is varied by adjusting a spring 54 on a rod 55 connected to the lever 52.

Abstract: 646,147. Washing gases. AMERICAN AIR FILTER CO. July 10, 1947, No. 18260. Convention date, Sept. 15, 1942. [Class 55(ii)] ] A dust arrestor of the type wherein dustladen air is centrifuged against a wet surface comprises a tank containing liquid and divided by a partition into supply and outlet sections, an S-shaped air passage being defined by curved baffles arranged in the tank, the inlet to this passage being so placed with regard to the operating liquid level in the tank that. with air being drawn through the apparatus at sufficient velocity, a continuous film of liquid is swept upwardly into said passage and flows in the form of a curtain from the end of each concave baffle surface across the adjacent air flow to the beginning of the next, the last curtain discharging into the drainage section of the tank. In the form shown the arrestor 1 is divided into a work space or inlet chamber 3 and an outlet chamber 6 by a partition 5 which terminates near the surface of liquid contained in a bath 4. The partition is provided at its lower end with a baffle R which is curved to provide a lower convex wall 11 and an upper concave wall 12. Another baffle L is mounted in the tank with its concave wall 10 opposite the portion 11 of baffle R, so that air passing between the baffles does so in an S-shaped path. The lower edge of baffle 10 is placed below the level of liquid in bath 4. An exhaust fan B draws air downwardly through a grill-like work bench 8, where it picks up dust at such velocity that the liquid level at the entrance to the S-shaped path is depressed and liquid is swept by the air up the concave surface 10, across the air stream to concave surface 12 and, on leaving this surface. the liquid again crosses the air stream and drops back with the dust which it has extracted from the air in the S-path into a removable screen basket 4a in the tank 4. The cleaned air passes up the outlet chamber 6, entrained water being removed by baffles 7.
