Title: Improvements in electric motor starters
IPC: H02P1/02
Filed: 1923-03-06
Abstract: 218,702. Hirst, J. A., and Brook, Hirst, & Co., Ltd. March 6, 1923. Controllers with overload release.-Relates to motor-starting switches with overload release control, the sensitiveness of which is reduced during the starting period. According to the invention, the sensitiveness-reducing device comprises a movable platform supporting the plungers of several overload coils, and a yielding mechanical connection whereby the platform is raised and lowered by movements of the starter-operating handle. The Speoincation describes two types of alternating-current motor-starting vehicles embodying the invention. In one type a to-and-fro movement of a handle intermittently advances a cam-shaft which actuates a circuit-breaker and connection-changing switches as described in Specifications 207,232 and 212,601. To actuate the sens tiveness-reducing device, the intermittently advancing shaft F, Figs. 1 and 3, has an additicnal cam 9 which, through a yielding linkage 5 rocks a counter shaft K<2> and thus raises and lowers rods 2, Fig. 2, carrying the platform 1 supporting three overload plungers O<22>. Adjustability of the platform is provided by a screwed collar 11, and of the separate plungers by setscrews 14. An additional movement of the shaft F beyond full running position is required to restore the sensitiveness to normal, and the handle mechanism is arranged to open the switches if left in the condition of reduced sensitiveness. In the other type of starting switch, a contact member Y, Fig. 7, is moved between two stationary contact members v, v<2> to obtain the starting and full-running positions, as described in Specification 225,739. A linkage 15. 17 transmits the movement to springs 19 and suspension rods 18 for the overload plunger platform, and thus reduces and restores the sensitiveness in a similar manner to the first embodiment. Specification 166,084 is referred to in the Provisional Specification.

Title: Yarn spinning machine
Inventor: HARRIGAN CORNELIUS HERBERT
IPC: D01H1/02
Filed: 1947-03-10
Abstract: 639,201. Spinning and winding yarn. HAYS, J. H. March 10, 1947, No. 6694. [Class 120 (ii)] A spinning machine of the kind wherein drawing, spinning and winding are sequentially performed, for a given length of roving, has its drafting section vertically movable in relation to the machine frame, means being provided for moving the section vertically as the bobbin building mechanism moves vertically to build the bobbin. The shaft 33, connected to the main drive 103, rotates a cam 32 to oscillate a building mechanism 28 which, through chains 25, 22, reciprocates a bar 24 and the ring rail rods 20, the usual pawl and ratchet effecting the upward " gain " for bobbin building. The upward motion of the ring rail, through a chain 56 gradually advances a rod 51 carrying microswitches 54 which are opened and closed by dogs on the reciprocating rod 24 so to operate a motor 43 which, through a chain 421, shaft 42 and worm wheel 46, effects the rotation of jacks 17 to lift the drafting section 3 of the frame upwardly with the upward " gain " of the ring rail, the vertical movement of the drafting section being controlled by links 16. Limit switches are operated by an arm on the draft section to open the motor circuit at the top and bottom limits of motion. The main drive 103 also operates the draft 120 which, through a clutch 121, drives the highest speed roller of the six-roll drafting section the gear train including gears on pivoted " extensible links 117 to allow for uninterrupted drive to the roller 122 throughout its upward motion. The roller 122 through gear trains 129, 1291 drives the other rollers of the drafting section. Fixed to the ring rail, and partaking of its vertical motions, are balloon arresters 83 extending from a rotatable shaft 84 which allows for adjustment of the fingers 83 and also for them to be turned to a vertical position during doffing. The pigtail guides 7 are mounted upon a rod 91 carried in brackets 92, slidable upon rods 93, the brackets being attached to counterweighted arms 94. After the ring rail brackets 11 have risen a predetermined amount, they contact the brackets 92 which thereafter move the guides 7 in unison with the ring rails. A ratchet arrangement is included whereby the operative may manually change the position whereat the guides 7 begin to move with the ring rail. The last drafting roll 122 is cleared by a felt-covered roller 130, mounted in a housing 133, and by a felt strip 131 pressed against it by weighted arms 134; the top roller 128 being cleared by a felt strip 132. In order that the draft section may be returned to its lowermost position, a parallel circuit to the motor 43 is arranged, so that the manual closing of a switch will energise the motor, in reverse, thus lowering the jacks until the lower limit switch opens to stop the motor. The yam guide roller 140 is grooved to allow passage of yarn and to restrict size of upper balloon.

Title: Improvements in effecting gaseous dehydrating reactions
IPC: C07C51/56
Filed: 1928-03-05
Abstract: 316,898. Ewan, T., Roberts, H. M., and Imperial Chemical Industries, Ltd. March 5, 1928. Acetic anhydride ; esters.-Readily reversible gaseous reactions involving the splitting off of water and the use of a dehydrating catalyst are effected in the presence of carbon monoxide and a catalyst promoting the reaction between carbon monoxide and steam. The initial reagents may be mixed with carbon monoxide and the mixture passed under suitable temperature conditions over a dehydrating catalyst mixed with a catalyst promoting the reaction between carbon monoxide and steam. Since, however, the optimum temperature for the dehydration may differ from that for the reaction between carbon monoxide and steam, the catalysts are preferably used in succession, the second catalyst being generally at a lower temperature than the first; the space velocities of the gases may also differ in the two stages. When the catalysts are used in succession, the carbon monoxide may be added after the first stage, or a part may be added before the first stage and further amounts added subsequently, particularly in order to cool the gases. In the example, a mixture of acetic acid vapour with carbon monoxide is passed at 500-600‹ C. over sodium metaphosphate and then at 350‹ C. over a catalyst prepared by heating manganous carbonate in a current of carbon monoxide at 300-500‹ C., a mixture of acetic anhydride and acetic acid almost free from water being obtained ; iron should be excluded from the reaction system. Reference is made also to the formation of esters in the gaseous phase and, in one of the Provisional Specifications, to the production of hydrocyanic acid from formamide. Specification 305,147 is referred to.

Title: Improvements in or relating to Steam Turbines.
Inventor: CAMPBELL JAMES ALLAN
IPC: F01D17/00
Filed: 1918-04-25
Abstract: 125,761. Campbell, J. A. April 25, 1918. Working-fluid supply; regulating.-Relates to means for reducing the temperature of superheated or high-temperature steam on its way to a turbine or reciprocating engine, and is specially applicable to astern turbines, which are liable to damage on the sudden admission of hightemperature steam. Cooling water by-passed from the feed or boiler water is injected into the steam in its passage from the stop-valve B, Fig. 2, to the turbine, the water being conducted to an atomizing rose past a valve C for regulating the quantity and a valve D for regulating the admission, while valve D is inter-connected with the steam valve B by operative gearing so that both valves are opened simultaneously, or the water valve slightly in advance of the steam valve. The gearing may be arranged so that, while steam can never be initially admitted without water also being admitted, the water valve may be subsequently closed independently of the steam valve, and further so that when the steam valve is closed the mechanism i n t e r - connecting the valves comes into engagement again, enabling both steam and water valves to open together when next required. The gearing may comprise an axially moving shaft F arranged between the valve spindles and carrying at one end a screwthread on which is mounted a bevel wheel carried in a fixed bearing and meshing with a similar wheel on the spindle controlling the water valve D. The other end of the shaft slides on a feather in a hollow shaft on which is fixed another bevel wheel meshing with a similar wheel controlling the steam valve B. Adjacent to the shaft is a stop H adapted to be manually moved into or out of engagement with an abutment on the shaft, whereby endlong movement of the shaft is prevented or permitted, according to whether both valves are to be operated simultaneously or independently. Other forms of operative mechanism connecting the valves are described. Fig. 3, for example, shows a construction wherein both bevel gears are fast on the shaft F, and the spindle of the valve D is provided with a screw-threaded portion engaging a rectilinearly guided cup J, which is under the influence of a spring tending to close the valve, the cup being restrained from such movement by a catch K controlled by a hand-lever.
