Title: Improvements in and relating to sliding clasp fasteners
IPC: A44B19/04
Filed: 1943-07-24
Abstract: 567,466. Sliding - clasp fasteners. PLASCO, Ltd. (Morin, L. H.). July 24, 1943, No. 12080. Addition to 563,843. [Class 44] In a sliding - clasp fastener of the kind described in the parent Specification the aperture through each fastening member described therein for engagement by a pin or projection on mating fastening members to prevent separation of interengaged members when the stringers are flexed, is replaced by a groove or channel 20 extending across the free end face of the member. As shown, each member, secured on the beaded edge 11 of the stringer tape 10 by jaws 15 has, on opposite faces, transverse angular grooves 18 immediately behind angular transverse ribs 17. The sloping faces of the ribs, and also those of the grooves, are shown as approximately at right angles to each other and as extending at right-angles to the plane of the stringer tape. Projections 24 are provided extending into the.grooves 18 and of rounded form corresponding with the crosssectional form of groove 20. When fastened by the usual slider, not shown, the ribs 17 of each fastener member nest in the grooves 18 of a pair of co-operating fastener members on the other stringer, projections 24 on said pair engaging end to end in groove 20 to prevent separation in a direction at right-angles to the tapes 10. As shown in Fig. 2, the projections 24 end flush with the transverse surfaces of the jaws 15, but modifications are described in which they project beyond those surfaces to form pin-like extensions which also extend rearwardly into juxta-position with the heads 11. In one of these modifications the projections occur in one only of the pair of grooves 18. In a further modification the ends of the pinlike projections are rounded as at 38, Fig. 5,. to provide ball-and-socket engagement with the grooves 20, and the angular ribs and grooves converge from the centre outwards as in Fig. 5 to allow transverse rocking movement between adjacent fastened members without disengagement if the stringer tapes be flexed. Fig. 3 shows a modification in which the jaw portions 29 engage the tape head at an angle whilst the engaging portions 28 project at rightangles to the tape edge, the end connecting member 30 for the tapes being correspondingly angular as shown. The symmetrical formation of the members allows closure with a slider disposed either way round, and a slit closure is described having a pair of oppositely disposed sliders, closure being effected by moving either slider towards the other.

Patent GB-201626-A (GB)
Title: Improvements in valves
IPC: F16K3/18
Filed: 1922-05-02
Abstract: 201,626. Turner, D., and Davison, R. May 2, 1922. Pilot valve apparatus; wedging or jamming.- A sluice valve is actuated by a piston device under control of the pressure in the main. The valve is formed of two discs held together by a central spindle having right and left-handed threads, and carrying a pinion which is engaged by a rack L to separate or close the discs. Relative rotation of the discs is prevented by three guide pins l. The discs carry pins K by which they are lifted by a bridge G. The arms H carry guide rollers I which run in grooves cut in the casing. In a modification, Fig. 3, the valve discs are actuated by levers d working between wedges f, g. The wedges are arranged on opposite discs so that the discs are opened or closed by means of the levers, on operating the spindle o. The valve is actuated by a spindle E, Fig. 7, carrying a crosshead D, by means of a hydraulic cylinder B. The cylinder receives the pressure fluid from the main when this has exceeded a predetermined limit, by means of a pipe U, Fig. 10, which is connected to a pilot valve apparatus secured to the upper side of the main pipe. Pressure fluid passes from the main through a pipe V, and presses a piston N against the action of an adjustable spring O. The port S is uncovered at a predetermined pressure, allowing the pressure fluid to pass through a regulating valve T to the cylinder B to lift the valve. The valve may be used as an automatic delivery valve for centrifugal pumps. If the pressure falls, the piston N is moved to the right by its spring, so that the valve is allowed to close by the weight of the crosshead D or by a spring, and the liquid in the cylinder escapes by the valve T and port S to a waste pipe W. The valve may also be used as a self-closing valve in trunk water mains, provision being made to supply the cylinder B from either side of the valve. In operation, the cylinder and the pipe V are fed from the downstream side of the valve, so that an abnormal velocity and reduction of pressure allows the valve to close. The valve is reopened bv connecting the cylinder B to the pressure side of the valve.

Filed: 1957-04-18
Abstract: 848,858. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 18, 1957 [April 19, 1956], No. 12670/57. Class 40(9). [Also in Group XL (c)] Information read out of a storage core is automatically re-written by means of an auxiliary core biased to one stable state and switched to the other state by the coincidence of a read-out pulse applied to both cores and a pulse generated by the switching of the storage core; return of the auxiliary core under bias generating a signal to reset the storage core. As illustrated in Fig. 1, the row of storage cores 10, 11, 12 and the auxiliary cores 13, 14, 15 are driven in series by a read pulse applied over lead 20; any storage core holding a binary one being switched and all auxiliary cores of the row having their D.C. bias neutralized. If core 10 turns over an output is produced in its column wire which is applied to an amplifier 35 gated to receive the pulse by a pulse on lead 38 and having a biased rectifier in its input to discriminate between a full binary one output and the sneak output associated with read out of binary zero. The output of amplifier 35 triggers a pulse generator 45 (see Group XL (c)) the output of which is a pulse of a predetermined length and of sufficient amplitude in combination with the read-out pulse to switch the auxiliary core 13. At the end of the read-out pulse and the pulse from pulse generator 45 the auxiliary core returns to its initial state under bias and in so doing produces an output over link winding 70 to restore the storage core 10. To write information in the cores they are read out and the amplifiers 35, 36, 37 are inhibited by absence of a pulse on lead 38. Any pulse generator 45, 46, 47, triggered over leads 80, 81, 82, produces an output to switch an auxiliary core which on reverting under bias writes binary one in the associated storage core.

Title: Improvements in manufacture of paper filled with alkaline filler
IPC: D21H23/18
Filed: 1931-05-01
Abstract: 378,024. Making paper. HADDAN, R., 31, Bedford Street, Strand, London.- (Raffold International Corporation; P.O. Box 8, Shawsheen Village Station, Andover, Massachusetts, U.S.A.) May 1, 1931, No. 12920. [Class 96.] In making sized paper filled with alkaline filler, the filler or the acidic material such as alum or both are added to the mix under conditions which tend to minimize either the time or the intimacy of contact or both, the addition preferably taking place at or after the passage of the paper furnish from the dilution box when the mix is dilute and the interval to the passage over the web-forming device is short. The paper may be produced by adding to the fibrous material in the beater, size, alum and alkaline filler and then re-precipitating the size by adding more alum at the dilute stage. Any of the three ingredients size, alum or alkaline filler may be added alone to the beater and the other two be added at the dilute stage or if size is added at the beater stage filler or alum may be added with it and alum or filler be added later at the dilute stage. All three ingredients may be added at the dilute stage, previously precipitated alum size being substituted for the size and alum if desired. If alum is introduced into a beater containing alkaline filler, for example from " broke " or trim from the w.re, additional alum is added at the dilute stage to reprecipitate the size, but when such mixes are treated, " broke " &c. may be treated separately and the alkaline filler be added to it, the mixture being incorporated with the main mix at the dilute stage. In carrying out the operations, the amount of alum used is twice or more times the amount of rosin in the size and the size may consist of or comprise the size-paraffin emulsion described in Specification 333,620, [Class 96, Paper &c.]. If a paraffin emulsion made with an insoluble subsbance such as clay or alkaline filler or a gum, such as gum arabic or gum ghatti, to which dextrin may have been added, is used two substances which mutually precipitate one another, such as rosin, size, and alum, are used, the precipitation gathering the disperse phase of the emulsion on to the fibre. Sodium silicate or sodium aluminate may be added to or may replace the size. The action of the alkaline filler may be temporarily delayed just prior to its incorporation in the mix, by the addition of about 4 per cent of alum to reduce its alkalinity or by precipitating about it a small quantity of alum size. Sulphuric acid, sodium bisulphate, zinc salts or other aluminium salts may replace the alum and a synthetic rosin acid be used in place of natural rosin. Suitable alkaline fillers are calcium carbonate in the form of lime mud, calcium carbonate, magnesium basic carbonate, calcium carbonate, magnesium hydroxide, &c.
