Title: Improvements in or relating to method and apparatus for fiberizing molten material
IPC: C03B37/05
Filed: 1947-09-23
Abstract: 631,061. Mineral wool production. STEVENS, A. H. (Johns-Manville Corporation). Sept. 23, 1947, No. 25810 [Class 56] Apparatus for making mineral wool has a means 12 for discharging a stream of molten material 14, a rotor 18 positioned to receive the stream, and a second rotor 20 adjacent the first rotor and positoned to receive molten material discharged from the first rotor. Molten rock, slag, glass etc. 14 flows from the discharge 12 of the furnace 10 to the cylindrical or slightly coned rotors 18, 20 mounted respectively on shafts 22, 26 so that rotor 18 is tilted with respect to 20. In the example given the rotor 20 is on a horizontal axis and rotor 18 is tilted 12 degrees from the vertical. The rotors are driven in opposite directions and spaced about # to 3/32 inch apart, and the spacing and angle between them are adjustable. The peripheral surface of the rotor 20 has a series of small V-shaped grooves 28, and rotor 18 has similar grooves except at portions which receive the molten stream 14, where the recesses 30 are larger and of rectangular sections. A suitable peripheral velocity is about 13,000 ft./min. obtained with rotors of 11 inches diameter turning at 4,500 r.p.m., and conveniently there are 20 to 40 grooves 28 per inch. The material 14 contacts the rotor 18 to the left of the axis 22 and meets the grooves 30, some material bonds in these grooves to form a ring 32, but most is projected tangentially at increased speed and in slightly spread condition on to the peripheral surface of rotor 20. A bonded ring 34 is then formed, and the remaining material is projected back on to rotor 18 forming ring 36, and a further ring 38 may also be formed. The rings are temporary and may be stripped from the rotors whereupon new rings form. When the remaining material reaches the bight between the rotors it is levelled off and mixed with the material carried around each rotor, and when the rotor surfaces separate fiberization takes place, and the molten material on the outside of rings 32 etc. is thrown off and drawn out. A binder may be introduced into the fibre which is collected in any suitable manner.

Title: Improvements in and relating to grinding machines for attaching to the tool-posts of lathes and other machine tools
IPC: B24B27/00
Filed: 1920-09-09
Abstract: 172,420. Nugent, A. Sept. 9, 1920. Disc apparatus.-A grinding-attachment for fixing to the tool-posts of lathes &c., and of the kind in which an abrasive wheel fixed on a shaft is rotated and axially reciprocated from the same primary source, either hand or power, comprises an abrasive wheel 20, Fig. 1, mounted on a pinion-shaft G, which is rotated and reciprocated. Rotary motion is transmitted from a handle B through gears D, D', E, F to the pinion shaft G. The traverse is obtained by a differential screw motion; the gear D<1> is integral with a sleeve carrying a gear J and having splined therein a shaft K, which is threaded to engage a nut M having a gear cut on its periphery and axially constrained between the gear J and a projection N. The gears J, M rotate at slightly different speeds, and thereby cause axial movement of the shaft K, which is transmitted to the shaft G through a coupling R slidable on shafts S<1>, S<2>, Fig. 2. The gear J meshes with gears T<1>, T<2> mounted on the shafts S<1>, S<2>, and the gear M meshes with gears V<1>, V<2> freely mounted on the shafts S<1>, S<2> and slidable by means of a lever x pivoted at 14 and having pins W<1>, W<2> engaging grooves in the gears V<1>, V<2>, so that one or other of the gears engages by means of clutch-teeth the adjacent gear T<1> or T<2>. The gears T', V<2> have an equal number of teeth, and they have one or more or less than the gears T<2>, V<1> which also have an equal number, and the gears J, M have an equal or approximately equal number of teeth. According to which pair of gears T', V<1> or T<2>, V<2> are clutched together, the gear M rotates either slower or faster than the gear J and thereby traverses the shaft K to the right or left. Towards the end of each traverse, a pin Y on the slidable coupling R engages a shaped lever 5 pivoted at 14 and moves it towards its central position, and when just over that point the lever 5 is shot over by a V-shaped spring plunger 7. A pin 8 or 9 on the lever 5 contacts with and moves the lever x which is retained in position by a spring plunger 15 till the lever 5 has moved past its central position. The lever 5 may also be shifted by a stud 10 projecting through the cover of the attachment. A clamp for holding a diamond or like tool for trueing the wheel is provided.

Abstract: 463,112. Tensioning arrangements for belt gearing. PINCKNEY, V. Sept. 19, 1935, No. 25956. [Class 80 (i)] [Also in Group XXII] A belt-driving unit for a machine is adjusted to alter the belt-tension by rotating a drum in which the shaft carrying the driving pulley is mounted eccentrically. The driving unit may be housed within a stand, Fig. 1, and may form part of a treadle driving arrangement. The drum A, carrying the eccentrically mounted crank-shaft B, is rotatable within the bearings C to tension the driving belt. The connecting rod H, Fig. 2, has an adjustment 1 to prevent the treadle F touching the floor when the drum reaches its position of maximum adjustment. In a modification, an electric motor is used to drive the shaft 13 through gearing. The adjustment of the drum may be effected by a tommy bar and the drum secured by a strap, or a worm engaging teeth on the periphery of the drum may be employed.

Title: Improvements in or relating to processes for extracting and reconstituting witch hazel
IPC: A61K36/185
Filed: 1956-08-28
Abstract: A method of preparing a witch hazel extract, from which commercial distilled witch hazel may be reconstituted, comprises mixing an adsorbent such as activated carbon, which is preferred, or charcoal, animal charcoal or powdered willow charcoal, amounting to 0.1-1.0 per cent by weight of the mixture, with witch hazel water for a period of time, preferably 30 minutes, sufficient for the carbon to adsorb the witch hazel essence from the water, and then separating the carbon odorant adsorbate from the liquid by centrifuge or filtering; or allowing witch hazel water to percolate through a bed of the adsorbent.  The witch hazel may be reconstituted by eluting the adsorbate with ethanol, grain alcohol or aqueous alcohol containing 50-95 per cent ethanol, separating the liquid from the carbon by centrifuge or filtering, washing the carbon with water, and combining the alcohol filtrate and the washings to give commercial distilled witch hazel containing approximately 15 per cent alcohol. Examples of the production of the adsorbate and the reconstitution of the distilled witch hazel from the adsorbate are given.

Title: Improvements relating to lathes
Inventor: HAWES ROBERT CHARLES
IPC: B23Q1/68
Filed: 1957-08-22
Abstract: 838,630. Lathes. HOLTSPUR ENGINEERING CO. Ltd. Sept. 30, 1958 [Aug. 22, 1957], No. 26505/57. Class 83 (3). In a screw-cutting &c. lathe in which a toolholder 8 is mounted on a cross-feed slide 17 supported on the lathe-saddle (not shown), means 20 on the slide is carried by traverse of the saddle against an abutment 22 to retract the tool-holder relatively to slide 17. A plunger 6 operated by a double-acting pneumatic &c. cylinder 12 supports the tool-holder, and is mounted on a tool-post 3 on slide 17. A pair of resilient abutments 22, 23 are mounted on the tailstock 2. Screw-cutting in direction " X " is terminated when the end 20 of a valve-slide 30 contacts abutment 22 and re-sets valve 19, which then re-sets a further valve 13 on cylinder 12, by means of compressed air fed along lines 25, 27, 15. In this setting, valve 13 causes cylinder 12 to retract the tool, by compressed air from a line 14, until an abutment 10 on plunger 6 strikes mounting 4. Valve 19 may also arrest saddle traverse. At the end of the idle return stroke of the saddle, the other end (21) of the valve slide contacts abutment 23, reversing valves 19, 13 and returning the tool to its advanced position. The ends 20, 21 are of conical form so that as the cross-slide is fed to increase the depth of cut, saddle traverse is shortened. The Provisional Specification refers also to the use of a lever-operated valve 19, and mechanical or electrical means for operating the tool holder 8.
