Title: Improvements in or relating to suction devices for cleaning carding cylinders
IPC: D01G15/80
Filed: 1923-02-21
Abstract: 207,095. Weinbrenner, J. Feb. 21, 1923. Cleaning machinery pneumatically.-A suction device for cleaning carding cylinders comprise nozzles carried along a double-threaded shaft by a carrier provided with guide forks bearing en a guide rod parallel to the shaft. This shaft may be driven from the shaft of the carding-engine: the carrier may be arranged to be tilted out of the way. The Figure shows a form in which the guide rod c is fixed eccentrically by pins k in discs d mounted in bearing rings e which form part of the brackets a carrying the screw threaded rod b. The nozzle carrier is formed with nozzles for the carding cylinder and the doffer, and is provided with guide forks i which in one position of the guide rod, bear against it. When the screwed pins have been withdrawn, and the discs rotated to bring the rod clear of the guides, the carrier tilts until a projection u on it engages a stop v, when the nozzles are swung out of the way of their cylinders. In a modification, the guide rod c is fixed to the brackets, and the guides i are attached by a screw to the nozzle carrier, and may be disconnected from it. The carrier is formed in two parts adjustably screwed together to allow the nozzles to be swung out of the way. The screw-threaded rod is rotated from the engine shaft l through a chain r, a wheel n loose on the shaft, and an arm p fixed on the shaft and carrying a pin q which may be caused to enter one of the holes o in the wheel. Grooves are formed at the ends of the screwed portion of the rod in which the pin of the carrier may rest at the ends of its travel until, being given a slight push, it again engages the thread.

In a coiling mechanism, sliver 19 supplied from condensing rolls 9 passes around guide bars 21,22 through an opening 18 in gear 16, through trumpet 4 and is grasped by rolls 5 which feed it upwardly through an eccentrically located opening 3 in a turntable 2 which lays the sliver, into a can 1 rotating therewith, in the form of a hypocycloid the coils of which are secured from displacement by a vertical rib 20. The sliver is removed for further processing from the upper open end, or an outlet aperture (not shown), of the cam. The cam is caused to rotate relative to its own axis, by means of crank mechanism 11, 12, driven from shaft 8 through bevel gears 13, 14, while the axis of the cam, eccentrically positioned on the turntable 2, describes a circular path: the arrangement is such that the orientation of the cam is unchanged, i.e. the cam changes its positon in a cyclic manner.

Title: Improvements in boiling reactors
IPC: G21D5/06
Filed: 1957-02-15
Abstract: 852,293. Nuclear reactors. GENERAL ELECTRIC CO. Feb. 15, 1957 [Feb. 16, 1956], No. 5227/57. Class 39(4). In a self-regulating boiling water reactor the upper and lower zones have different volume ratios of moderator to fuel and, normally, boiling occurs only in the upper zone. Simultaneous steam bubble formation in both zones causes the reactor to fail safe. The effect of bubble formation is opposite in the two zones ; an increase in steam formation in the upper zone causes an increase in reactivity while in the lower zone the reactivity is decreased by bubble formation. In one embodiment, Fig. 3, the difference in volume ratios between the two zones is effected by the fuel rods 10, 11, 12, of different lengths, immersed in the light water liquid moderator and coolant 13, enclosed in vessel 14. Alternatively, plates may be used in place of rods. In further embodiments, Figs. 5, 6, a solid graphite moderator 28, is mounted between the face elements 27. Either 27 or 28 may be tapered, to give the required ratio charge along the coolant channels 29. In a further arrangement, not shown, the present system is applied to a reactor of the form disclosed in Specification 822,032. The fuel may consist of uranium 233 or 235 or plutonium incorporating fertile uranium 238 or thorium 232 for breeding purposes.

Abstract: 339,202. Gas Accumulator Co. (United Kingdom), Ltd., (Assignees of Svenska Aktiebolaget Gasaccumulator). Feb. 16, 1929, [Convention date]. Lighthouse and like lamps.-In a lighthouse or like signal lamp a plurality of separate means are employed for periodically supplying gas to a burner, or to a plurality of burners constituting a single source of light, the gas supplying means being interconnected so as to operate simultaneously, and safety means preferably being provided whereby the operation of one means causes the operation of another. In the form of flasher shown in the Figure, gas from a pipe 10<a> enters and leaves a casing 1<a> through inlet and outlet ports 11<a>, 13<a> and then some of it passes through pipes 12<a>, 20<a>, 22<a> to burners 21a. a pilot burner 23a being supplied with gas by means of pipes 25a connected directly to the pipe 10<a>. The inlet and outlet ports 11<a>, 13a are controlled bv a pivotally mounted valve member 6a associated with springs 14a, 15a and connected at 16a to a flexible diaphragm 2<a>, whereby the flow of gas is made intermittent. The valve member 6a is also connected to a rod 35a which carries a flexible diaphragm 34a adapted to close an opening 33a in the bottom of the casing 1<a>, and also a flexible diaphragm 32a adapted to close the'top of a chamber 31a secured to the bottom of the. casing 1<a>. A pipe 30a leading from a chamber, similar to the chamber 31a, secured to the bottom of a second flasher, also is connected to the outlet pipe 12a, whilst a pipe 30b from the chamber 31a is connected to the outlet pipe of the second flasher. This interconnection forms a safety device whereby, should the valve member 6<a> not be operated by its own flexible diaphragm 2a, it is automatically operated by the auxiliary flexible diaphragm, similar to the flexible diaphragms 32a, 34a of the second flasher, and vice versa.

Separation of a gas mixture e.g. coke oven gas into gaseous methane and liquid ethylene is effected by partially liquefying the mixture by passing it around vertical tubes 9 within a casing 8 having a gas mixture inlet 4 the mixture being cooled by heat exchange with at least part of the so liquefied portion, after expansion at a valve 14, flowing down the inner walls of same of the tubes 9 as a thin film and being thereby rectified. Pure liquid ethylene is discharged from the bottom of the tubes 9 through a duct 21 and gaseous methane is discharged from a collecting chamber 16 through a duct 18 and an expansion valve 19 where it is joined by gaseous methane from another similar heat exchanger (not shown). This methane together with methane from further exchangers in ducts 23-25 flows down the interior of the remaining tubes 9 and thus cools the crude ascending mixture and is discharged through ducts 26 ... 28. Unliquefied gas leaves the casing 8 through a duct 10. Specification 801,493 [Group XII] is referred to.
