Title: Electro-chemical method and apparatus
Inventor: JESSOP GILBERT
IPC: G01N27/48
Filed: 1962-02-06
Abstract: 1,009,111. Determining relative quantities of fluid mixture constituents. CAMBRIDGE INSTRUMENT CO. Ltd. Jan. 3, 1963 [Feb. 6,1962], No. 4588/62. Heading G1N. In an arrangement for measuring small concentrations of silica in aqueous solution by means of an A.C. polarograph the silica is converted into a complex which can be measured. The solution may be treated with molybdic acid in the form of a molybdate, e.g. ammonium molyb-. date and sulphuric acid may be added to bring the pH to between 1 and 5. The solution may be heated and cooled and tartaric acid added. The heating and cooling serves to eliminate some peaks from the polarograph and to render others independent of pH. This is discussed with reference to Fig. 1. Water such as boiler feed water in pipe 1, Fig. 2, is made to flow at a constant rate by a fixed head arrangement 2, a solution of ammonium molybdate is added at a constant rate through a tube 4 and sulphuric acid through a tube 5. The pipe 6 is of such a length as to allow completion of the reaction and the pipe is heated and cooled at successive points. A constant flow of tartaric acid is supplied at 7 and the polarographic measurement is effected in a cell, A.C. being superimposed on D.C. from source 11 by an oscillator 12. The current flow through phase sensitive rectifier 13 is recorded by a recorder 14. The choice of cathodes for different concentrations is referred to, the dropping mercury type being preferred. Peak currents may be stored prior to recording. Specifications 640,768 and 776,543 are referred to.

Title: Improvements in winding apparatus for paper and other web material
IPC: B65H19/26
Filed: 1927-02-18
Abstract: 269,860. Beloit Iron Works, (Assignees of Berry, E. E.). April 26, 1926. Winding webs.-In a web-winding apparatus, particularly for a papermaking machine, or a slitting and rewinding machine, in which the winding-shaft rests upon and is driven by a pair of winding-drums, one of the drums is pivotally mounted with respect to the other drum to facilitate lifting and discharging the wound roll. The winding-spindle 8 with the partially wound roll 60 rests on the drums 6, 7 between which the web 4 passes. The drum 7 is mounted in arms 14 pivoted about the axis of the drum 6 but normally resting upon the floor 18. Links 19 connect the arms 14 to spindles 23 vertically slidable in guides 24 and having screwed portions engaging nuts operable to raise and lower the spindles by worm gearing actuated by a reversible electric motor 35. The winding- spindle 8 is carried by rods 41 slidable through guides 42 pivoted about a cross shaft 43 carrying fast and loose chain wheels over which pass chains secured at one end to the rod 41 and carrying weights 51, 52. The weights 52 acting upon the fast chain wheels are much heavier than the weights 51 hanging from the loose wheels. The shaft 43 also carries a fast chain wheel 33 connected by a chain 54 to a wheel 55 to which is secured a gear wheel 58 provided with a locking dog 59 which acts to lock the shaft 43 against rotation. During the winding operation, the bars 41 are gradually raised by the increase in diameter of the roll, the weight of the roll and bars being partly counterbalanced by the weights 51. If the web should break, the motor 35 is started and the dog 59 is raised to release the shaft 43 to allow the weights 52 to assist the motor in raising the roll. As the arms 14 are lifted the roll is moved by the drum 7 on to the top of the drum 6. The dog 59 is then placed in locking position to retain the roll in its raised position while the drum 7 is lowered to allow the end of the web to be threaded between the drums and pasted to the roll. The drum 7 is then raised into contact with the roll, the sraft 43 is released and the drum 7 returned to normal position, the roll following by gravity. When the roll is completely wound it is raised as described above and allowed to roll down an incline 61 to a support 62.

Abstract: 764,962. Knitting-machines. HOOKNIT, Ltd. Feb. 17, 1954, No. 4667/54. Class 74 (2). Old loops on the skeins of axially reciprocating hook needles 1 are transfixed by the downwardly bent points of co-operating instruments 31, are held by these points during the descent of the needles to draw new loops therethrough and are then relinquished, for casting-off, by the rise of the instruments 31. The instruments are then lowered again so that yarn can be laid for the next course, the co-operating parts of instruments and needle stems being formed with channels 1c, 31c so that the tip of each may be housed in the other. The side limbs of the channels 1c extend forwardly beyond the imaginary lines passing through the free ends of the needle hooks and extending parallel to the needle stems. The downwardly extending parts of the instruments 31 are so short that, when the instruments are lowered and the needles raised, a yarn receiving gap is left between the instrument and the tip of the needle hook. The needles are reciprocated by a horizontally reciprocating rail 17 acting through a crank 14 to oscillate a cam disc 11 and so reciprocate vertically a needle holder supporting rail 3, through rollers 9, 10 carried on the rail. The support rail 33 for the points 31 may be similarly reciprocated but vertically, or may be swung around a pivot situated at about the level of the free ends of sinkers 21. The sinkers 21 are reciprocated across the needle line by an oscillating arm, acting, through arms 25, on a slidable support rail 23. Alternatively, the sinkers may be of conventional shape, with two noses 21a, 21b and disposed at the front side of the needles; or stationary plain sinkers may be used, with a holding-down rail fitted over the fabric close to the rear of the needles. The arrangement may be used with loop wheel and other similar warp knitting machines, the needles being arranged axially or radially and for simultaneous or successive operation. For this purpose, the pointed instruments may be supported either on rails or on rings which may be raised and lowered or by eccentric discs and the needles may be arranged to move singly or in groups. The forwardly projecting channelcontaining parts of the needles may be provided by a bend in the needle, Fig. 1, or by a widened part thereof, Fig. 6.

Abstract: 655,379. Hopper discharge. THOMPSON PRODUCTS, Inc. Feb. 19, 1948, No. 4910. Convention date, Nov. 27, 1946. [Class 78 (i)] [Also in Group XXII] In a device for feeding articles S in an orderly manner from a bin 15 to a press or the like, a reciprocating vane 17 in the bin having a trough 17a along its upper edge picks up the articles when lowered into the bin and slides them along when raised and tilted to feed them to the top of a transversely disposed inclined ramp 20 down which they roll in side by side relation to be successively ejected at the lower end. The bin 15 for the blanks is supported on a frame 16 above the level of the press die 13 and the vane 17 is pivoted at 18 therein and passes through a slot in the base. The vane 17 reciprocates between the position at the bottom of the bin where it receives the blanks and the position shown where the blanks slide into the top of the transverse ramp 20. A pusher plate 24 pivoted at 18 to the bin and coupled to the vane operates a plunger 21 on each lowering of the vane and feeds a single blank from the bottom of the ramp, advancing all the blanks one step forward along a track 22 in a furnace 23 and pushing a heated blank on to the top of a ramp 33 where it slides by gravity to a carriage 35 by which it is fed to the forging die. A geared motor 30 reciprocates the vane 17 and pusher plate 24 through a bell-crank 26 and push rods 25, 28, the speed of the motor being regulated to feed the blanks in time with reciprocations of the carriage 35. The blanks pass through a shoot 34 into a chamber 36, Fig. 4, in the end of the carriage 35 which slides over the press table 50 and die 13 under the action of a piston 41. A readily replaceable bar 38 spans the chamber 36 to prevent the blank from tipping while allowing retraction as soon as the blank begins to drop and is the only part of the carriage which would be struck by the ram 11 in the event of failure of the carriage to retract. The piston 41 is operated from a compressed air supply 46 through a solenoid valve 45 controlled by movement of the ram 11.
