Title: Method and apparatus for winding a thread onto a bobbin
IPC: B65H54/32
Filed: 1956-05-07
Abstract: 791,896. Winding yarns. SOC. RHODIACETA. May 7, 1956 [June 8, 1955], No. 14126/56. Class 120(2) Thread is fed to a bobbin having conical end checks through a guide slot in a thread guide adapted to oscillate with constant amplitude about a fixed point and the thread guide given a sudden appreciable increase in angular velocity slightly before the points at which its direction of motion is reversed, and 'rapidly restored to its initial angular velocity slightly after the change of direction has occurred. A thread guide lever 1, pivoted at 2, is connected by means of a slit 4 and pin 5 with a member 6 pivoted at 7 on a reciprocating rod 8 which oscillates the guide 1. A roller 10 is rotatably mounted on the member 6 and engages with one of the abutments 14, 15 on a fixed member 13 when the guide approaches a reversal point. This engaging of the roller 10 causes the member 6 to pivot about 10 and thus gives increased angular velocity to the guide 1 through the pin and slot connections 4, 5. Immediately after the reversal of the direction of motion of the rod 8 and therefore the guide lever 1, the member 6 continues to pivot about the roller 10 until it moves, away from the abutment, when the pivoting ceases; the member 6 is returned to its normal position by springs 11, 12 and the angular velocity of the guide 1 resumes its initial value. In a second embodiment, both the member 13 and rod 8 are reciprocated by a helical grooved cam. oscillation of the member 13 being parallel to but of smaller amplitude than and out of phase with that of the rod 8. This arrangement gives a larger or smaller increased angular velocity immediately after reversal than before according as the member 13 is lagging or leading the rod 8.

Patent GB-171719-A (GB)
Title: Improvements in the manufacture of artificial threads or filaments
IPC: D01D7/02
Filed: 1920-05-26
Abstract: A constantly-flowing stream of water or other liquid passes through the funnel or guide that leads the thread from the godet to the centrifugal spinning-box; the stream of liquid facilitates the progress of the thread through the funnel, so enabling a finer thread or a thread of lesser strength to be spun and a higher speed of spinning to be maintained; also, by a suitable choice of liquid, a desired chemical or physical modification of the thread may be obtained.  The liquid may be supplied through a small glass tube attached to the funnel-shaped upper end of the guide preferably arranged at such an angle as to cause a swirling motion in the liquid therein, and connected with a flexible supply-pipe so as not to interfere with the reciprocating motion of the guide; or the jet of liquid may be arranged to meet the thread before the latter enters the guide so that the thread is weighted and caused to pass through the guide without handling; or the jet may be arranged to touch the thread as it leaves the surface of the godet.  The supply of liquid is controlled by selecting a tap of the requisite bore, and the tap may be of the two-way type so that a temporary augmented flow may be arranged for.

IPC: G01R19/04
Filed: 1951-06-18
Abstract: 697,879. Voltage measurements. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 17, 1952 [June 18, 1951], No. 14448/51. Class 37. A circuit for measuring the peak value of a varying voltage includes a cathode follower valve, the cathode of which is connected through a rectifier to a peak voltage condenser, together with means for measuring the voltage across the condenser and means for discharging the condenser. A transient voltage, the peak value of which is to be measured, is applied to the grid of a cathode follower valve VI, Fig. 2, the cathode circuit of which includes a condenser C1 in parallel with a resistance R1. The peak values of the voltage across the condenser C1 are applied through a diode V2 to charge a peak voltage condenser C2 to the same voltage, so that when the condenser Cl discharges through the resistance R1 the condenser C2 remains charged to the peak voltage until a short-circuiting switch S is closed. The peak value is measured by an instrument M in the cathode circuit of a valve V3. In a modification, Fig. 3, suitable for measuring recurring voltages, the switch S is replaced by a valve V4 which is normally non-conducting. Positivegoing pulses applied to its grid cause it to conduct and partially discharge the condenser C2. In a modification, Fig. 4, the cathode circuit of the valve V3 includes a condenser C3 in parallel with the cathode resistance R2. Peak voltages generated across the condenser C3 are passed through a second diode V5 to charge a second peak voltage condenser C4 which is partially discharged when pulses are applied to the grid of a valve V6. The voltage across the condenser C4t is applied to the grid of a valve V7, in the cathode circuit of which is the measuring instrument M. The discharge circuits for the two peak voltage condensers C2, C4 are made conductive alternately so that the output voltage remains steady except when the peak voltage varies in amplitude.

Title: A process for the preparation of dialdehydes and diols
IPC: C07C47/12
Filed: 1948-05-31
Abstract: Glutaraldehyde or C-substitution products thereof are manufactured by reacting with water, preferably in the liquid state at about 50-200 DEG  C., a derivative of 3 : 4-dihydro-1 : 2-pyran which contains an organic group attached to the carbon atom in the 2-position of the ring through an oxygen atom, and a hydrogenation attached to each of the carbon atoms adjacent to the oxygen atom in the ring.  The corresponding 1 : 5-diols are produced by combining this hydrolysis treatment with a hydrogenation treatment carried out under a super-atmospheric pressure of hydrogen in the presence of a hydrogenation catalyst, preferably Raney nickel.  The reaction in either case may be carried out in the absence of any catalyst for the hydrolytic reaction, or in the presence of an acidic catalyst, e.g. a strong mineral acid, an acid-reacting salt, a material which will produce acid in situ or an organic acid, preferably water-soluble. The quantity of water may be about 1-100, preferably 2-10, mols. per mol. of the dihydropyran derivative.  The group attached through oxygen to the 2-carbon atom in the starting materials may be an acyl group derived from a carboxylic acid containing only monovalent and/or aromatic carbon-to-carbon bonds, but preferably a non-reactive hydrocarbon group, e.g. a cycloalkyl, aralkyl, aryl or alkaryl group or especially an alkyl group, preferably of 1-8 carbon atoms, or it may also be a second 2-(3 : 4-dihydro-1 : 2-pyranyl) residue.  Other substituents which may be present in one or more of the 3-, 4- and 5-positions include alkyl, aryl, aralkyl and alkaryl groups and olefinically or acetylenically unsaturated hydrocarbon groups.  The starting materials may be subjected to the process of the invention with or without isolation from the reaction mixture in which they have been formed.  Examples describe the preparation of glutaraldehyde itself and its a - and b -methyl derivatives; 1 : 5-pentanediol and its 2- and 3-methyl derivatives.

Abstract: 1378845 Rolling mills NIPPON KOKAN KK 27 March 1973 [28 March 1972] 14690/73 Heading B3M The individual stands of a tandem strip rolling mill are successively adjusted to change the degree of bending of their rolls, as a point a in a rolled strip 1 passes the stands, the point corresponding to a change in thickness of the strip due to a variation in the rolling schedule. When the point a reaches a detector 23, pulses from a bridle roll assembly 7 are counted in a counter 14 until a distance corresponding to l 1  is indicated (i.e. the point a has reached stand No. 1). An output signal from a signal generator 17 then passes to a computer 22, and the bending of the rolls in stand No. 1 is automatically altered. By a similar arrangement, pulses from the stands are successively counted down to indicate when the point a has reached the respective stands, and the roll bending of the stands is suitably changed. A compensating circuit 13 between the stands and the counter 14 takes account of any slip during rolling, and of variations in the bridle roll and mill roll diameters.
