Title: Improvements in or relating to presses
IPC: C14B5/00
Filed: 1923-02-13
Abstract: 215,460. British United Shoe Machinery Co., Ltd., and Keall, F. B. Feb. 13, 1923. Addition to 194,401. Cutting-out apparatus. - The invention described in the parent Specification has the pressing arm carried by a post which is actuated axially from a shaft X. The post fits loosely in upper and lower main bearings 2, 3 carried by the frame. Auxiliary bearings 5, 28 in front of the upper, and behind the lower main bearings are similar in construction, each comprising two levers 7, arranged at each side of the front to rear vertical plane of the machine, carrying at one end horizontal rollers 8 engaging a groove 10 in the post and at the other cam surfaces 14 engaging rigid backplates 15 attached to the frame. When the post is raised and the press is inoperative the rollers follow the groove and swing about pins 12 to close upon and hold the post vertical. On lowering the post the rollers tend to swing in a circular arc about the pin, thus withdrawing slightly from the groove and allowing the main bearing to act. The cam surface meanwhile restricts the drop of the roller and ensures the latter entering the groove on the next upstroke. The pins 12 carry an eccentric portion 11 by which the rollers are adjusted, the back plate being adjusted by set-screws 18. In a modification the upper auxiliary bearing comprises a ball bearing rigidly supported on the frame and having a tapered bore which supports a tapered extension of the post when the latter is in the raised, position. The leather 59 is drawn up through the bed of the machine, and is held during cutting by a spring urged roll 50. Specification 22023/05 is referred to.

Abstract: <PICT:0357470/IV/1> <PICT:0357470/IV/2> Artificial silk cakes are after-treated by supporting them on rods and passing them through a treating apparatus comprising a sprinkling machine and an immersion apparatus.  The cakes are transported through the sprinkling apparatus by means of reciprocating laths for example as described in Specification 357,908, and through the immersion apparatus by a chain conveyer. A transfer mechanism is provided for taking up the cakes from the sprinkling machine and depositing them on the chain conveyer of the immersion apparatus.  The transfer mechanism may comprise rocking levers provided with recesses in which the rods carrying the cakes are deposited in the last working stage of the reciprocating lath mechanism, and the weight of the rods and cakes causes the levers to tip and bring the rods into contact with the chain conveyer.  As shown in the drawings, the intermediate conveying members comprise swing levers 1 which are weighted so that they stand upright when not loaded.  In the last phase of the sprinkling machine, the transport rods 6, carrying the cakes are placed by the reciprocating laths into the recesses 5 of the swing levers.  The levers immediately tilt towards the side on which the dipping machine is located.  The chain conveyer 7 of the immersion machine with its claws 8 is so arranged that it can lift the bars 6 from the deflected swing levers and carry them away.  The claws 8 are weighted and pivoted so that they remain upright during the passage of the chain over the wheels 10 . . 13, and during the whole time of immersion. The movement of the chain conveyer is preferably intermittent and it may be synchronized with that of the lath mechanism.  The impact of an abutment bolt 4 of the swing lever 1 may be utilized for the purpose of starting the chain motor of the dipping machine.  A stopping device for the chain motor is provided for permitting a definite feed and also to regulate the speed.  The immersion tank 16 may be filled to such a depth that the entire zig-zag path of the chain conveyer is in the liquid.

Title: Improved method and device for the manufacture of warps or rayon with a high twist, specially crepe-rayon
IPC: D02H1/00
Filed: 1947-02-17
Abstract: 642,113. Creels for crepe rayon. ALGEMEENE KUNSTZIJDE UNIE N.V. Feb. 17, 1947, Nos. 4557 and 4558. Convention dates, March 28, 1946, and Nov. 29, 1946. Drawings to Specification. [Classes 120(ii) and 142(iv)] In a creel for warping crepe rayon, the yarns are drawn overhead from bobbins in such a way that their existing twist is increased and are taken through thread guides situated at a distance from the ends of the bobbins which is smaller than the radius of a full bobbin. In the case of cylindrical bobbins, twist increase is obtained by unwinding off the appropriate end of the bobbin; conical bobbins must have been so wound that twist increase occurs when unwinding over the smaller end. Preferably, the bobbins are horizontal and the guides (which may be eyelets of steel, porcelain, or ruby) are provided in the vertical flange of an L-section plate, the horizontal flange extending completely under a row of bobbins to prevent any loose yarns from becoming entangled with the row beneath.

Title: Improvements in electrical circuit interrupters
IPC: H02H3/06
Filed: 1921-02-09
Abstract: 162,267. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Proctor, J. H.). April 23, 1920, [Convention date]. Protective arrangements.-In a protective circuit-breaker of the kind which is opened on overload or short-circuit and is automatically reset when normal conditions are restored in the protected circuit, the circuit is so connected as to constitute when the circuit-breaker is opened the fourth arm of a Wheatstone bridge arrangement, two opposite points of which are connected through a tripping coil which, when normal conditions are restored, trips to the closed position an auxiliary overload switch which completes a closing circuit for the main overload, circuitbreaker. As shown applied to a direct-current circuit 3 supplying energy through the overload coil 8 of the auxiliary switch 7 and through the main switch 2 to the supply circuit 1, the auxiliary switch 7 on the occurrence of overload in the circuit 1 opens the maintaining circuit 5 of the main switch, which in falling closes, after a time interval, the contacts 12, 13, 14. The switch 7 is retained in the open position 'by a self-acting latch 9 until tripped by the plunger of a coil 20 when the overload ceases. The supply circuit constitutes the fourth arm of the wheatstone bridge connection 17, 18, 19, which is supplied with current only when the main switch is open. The coil 20 is connected across opposite points and the arms of the bridge are so chosen that only when overload or fault conditions cease to exist on the circuit the current in the coil 20 is adequate to raise its core, trip the switch 7 to the closed position, and energize the closing coil of the main switch. In the case of alternating-current circuits, an auxiliary source of direct current is employed for energizing the wheatstone bridge and for closing the main circuit-breaker.

Title: Improvements relating to means for delivering molten glass to machines which gather by suction
IPC: C03B7/00
Filed: 1929-02-14
Abstract: 315,345. Bullman Machine Co., Ltd., (Assignees of Hillmann, H.). July 12, 1928, [Convention date]. Delivering molten metal.-Relates to a furnace trough or forehearth from which charges of molten glass are gathered by suction into the moulds of a glass-blowing machine. The invention consists in providing a baffle which dips into the glass and ensures that only glass from below the surface in the tank flows into the forehearth. The trough d is secured to the wall of the tank b in front of an opening which is closed by a vertically-adjustable gate h and a fixed bridge i. A vertical rib m is formed in one with the gate h and serves as a pivot for a sickle-shaped floating baffle n. The baffle rests, as shown, with one end on the rib m and the other end on the side wall of the tank. Glass flowing beneath the gate h into the trough d must pass beneath the baffle, thus ensuring that only subsurface glass reaches the trough. The moulds of the machine move in a circular path k, and each mould is preceded by a stripper which forces the chilled glass to flow out of the trough under the bridge i into the furnace. The baffle ensures that this chilled glass is reheated before it can pass back again into the trough. The baffle may be pivoted on the tank wall instead of to the gate h, or it may be attached either to the wall or to the gate. Specification 314,480 is referred to.

Title: Improvements in or relating to the preparation or maintenance of a liquid having a desired chemical characteristic
IPC: G01N27/416
Filed: 1947-02-21
Abstract: <PICT:0644777/III/1> The amount of a constituent in a liquid is determined by dividing a sample into two portions, removing all the constituent from one portion, adding to it a known amount of another constituent which reacts similarly to the removed constituent, and comparing it with the untreated portion.  The comparing device may actuate means for varying the known addition of constituent until the two portions are identical, the known addition being equal to the content in the original sample.  Alternatively, the comparing device may actuate means for controlling the addition of a reagent to the body of liquid from which the sample is taken.  Referring to Fig. 1, chlorinated water, sewage, &c. in pipe 1 is divided into two streams the untreated being fed directly to an electrode 7 in one compartment of a cell 5, whilst the other is dechlorinated in an absorber 13 passed to a feed chamber 20, wherein the other constituent is added, and thence to an electrode 23 in the other compartment of the cell 5. Suitable comparing cells are described in Specifications 367,821 and 548,173, 548,174 and 557,612, [all in Group XXXVI].  The feed rate of the device 26, which adds the other constituent, is controlled by a reversible servomotor 32 through the parts 29, 30 and 31, the speed of the wheel 29 being shown on a tachometer 33.  The feed rate is adjusted for a zero potential through a galvanometer relay 35 the output of which after amplification in an amplifier 42 (e.g. as described in Specification 493,457, [Group XXXVIII]) is passed through the opposite wound shading coils 44 of the servomotor 32, which in order to prevent hunting, is switched on intermittently by a rotating cam 47.  Constituents which can be added include solutions of iodine, bromine, permanganates, ferricyanides and chromates.  The supply of chlorine to the main body of liquid from a supply 58 is controlled from the tachometer 33 by "high-low" contacts 50, 51 and a needle 34 which touches neither of the contacts when the amount of residual chlorine is at a predetermined value.  Specification 561,733 is referred to.
