Title: Method and apparatus for bending glass sheets
IPC: C03B23/027
Filed: 1958-05-06
Abstract: 840,993. Bending glass sheets. LIBBEYOWENS-FORD GLASS CO. May 6, 1958 [May 14, 1957], No. 14393/58. Class 56. In a sectionalised mould for bending glass sheets to varying complex curvatures including a twist at some points, particularly for vehicle windshields, each wing section 27 comprises side shaping-rails 32, 33 pivoted at 43, 44 to the stationary centre section 41 and connected at their outer ends by a cross-bar 34. The rails are of unequal curvature and length and the outboard end of 32 is higher than that of 33 so that the bar 34 slopes as shown in Figs. 6 and 10 (views from the right of Fig. 2). A locator 37 is provided at the low end of the bar 34. (The reference 40 denotes a contoured thermal strain bar). A serrated support a on stationary outriggers 52 lies within the confines of the wing section when the mould is open, Fig. 10, and the glass sheet G is then supported by a very limited portion of the bar 34, but chiefly by the member a. As the mould closes, an increasing width of the sheet becomes supported by the bar 34 until, by the time that the mould becomes closed, Figs. 2 and 6, the supports a lie wholly outside the confines of the wings due to the movement of the wings relatively to the stationary outriggers. Pads 55 linked to the wing sections are provided for supporting the central part of the sheet above the centre section 41 during the initial stages. A modification uses two moulds, each the mirror image of the other, each comprising one comparatively flat section and one wing section having an outrigger support whereby windscreens comprising two mirror image parts for eventual assembly with a central dividing bar are produced. In a further modification, the support a consists only of a single rod-like member having a rounded upper end for engaging the underface of the glass sheet.

Title: An improved addressing or like printing machine
IPC: B41L47/42
Filed: 1927-06-02
Abstract: 284,524. Krell, J. June 2, 1927. Platen-machines; addressing and like machines. -In an addressing or like printing machine of the kind wherein printing-plates 3 are advanced in procession along a guideway to printing position beneath a platen head 10 mounted on an oscillating arm 7 and wherein the member 10 is rotatable and carries a series of platens 11 - - 13, Fig. 1 or 41, 42, Fig. 9, adapted to be brought in turn into the operative position and to print from different parts of a plate, the member 10 is rotated by means of a hand-lever 26 or 48 connected thereto by gearing. As shown in Fig. 1, the member 10 is rotatable about a shaft 9 carried bv a forked extension of the arm 7 and has fixed to it a notched locking-disc 14 and a ratchet wheel 16. The lever 26 is pivoted to a segmental gear 21, which is rotatably mounted on a shaft 23 carried by the arm 7 and meshes with a gearwheel 17 carrying a pawl 19 engaging the ratchet 16. When the platen head 10 is to be turned, the lever 26 is pulled down, the first part of the movement being relative to the gear 21, and being utilised to release a hook 24 from a notch 15 in the disc 14, after which the gear 21 drives the gear 17 and the head 10 is turned until the hook 24 snaps into the next notch 15 and the next platen comes into the printing position. The lever 26 is then released and a spring 30 coiled round the shaft 23 returns the segment 22 to normal position against a stop. In the modification shown in Fig. 9, the platens 41, 42 are spaced 90‹ apart, and a locking-disc 44 is provided having two notches 45, 45<1>. A toothed sector 46 is arranged next to the locking-disc and engages a sector 47 pivoted at 49 to the arm 7 and fixed to the lever 48. A hook 50 is mounted on the pivot 49 and is spring-pressed into the notch 45. When the platen is to be changed, the lever 48 is rocked in the direction of the arrow and rotates the sector 46. A cam on the sector 46 raises the hook 50 out of the notch, a pin 52 on the sector meanwhile riding in a recess in the locking-disc 44. Further movement causes the pin 52 to rotate the disc 44 and with it the platen head 10 until the hook 50 snaps into the notch 45<1>, the platen 42 then being in the operative position. When the platen 41 is again required for use the lever 48 is swung back into its original position.

Title: Improvement in presses for inserting pins in workpieces
IPC: B25B27/00
Filed: 1944-08-04
Abstract: 581,049. Assembling 'force fits. JACK & HEINTZ RESEARCH CORPORATION. Aug. 4, 1944, No. 14955. Convention date, Oct. 8, 1943. [Class 83 (iv)] In a machine for inserting pins 16 into apertures 38 in a work-piece 5, such as the gimbal of a gyroscope, the pins are carried in slots 35 in an indexable head 6 mounted on a rack 9 movable vertically by a hand lever 7 and pinion 8 so that on a downward stroke a pin will be inserted in the work and simultaneously another pin will be supplied to the previously emptied slot 35 whilst during an upward stroke, the head 6 will be indexed to align another pin with the work and the emptied slot with a supply nozzle 24. The head 6 is yieldingly locked on a cylindrical extension 32 of the rack by a spring-pressed ball 27 and notches 31 on the extension and is prevented from rotating on the downward stroke by a spring-pressed pin 13 on a stationary bracket 12 engaging an axial groove 14 in the head. The pins 16 have screwed upper ends and fluted lower ends which are slightly larger than the holes 38 in the work and the pins are held in slots 35- by springs 34 so that during a downward stroke to force a pin 16 into the work the fluted metal will flow to cause a tight friction fit. Just before reaching the end of a downward stroke, a bolt 17 on a bracket 18 attached to the rack engages the plunger 19 of a valve 20 to admit compressed air from a supply pipe 23 to a pipe 22 containing a succession of pins 16 and terminating in the nozzle 24. This ejects the top pin 16 from the nozzle 24 into the empty slot 35 of the head 6, the air pressure being cut off as soon as the head begins to rise. On the upward stroke, the spring 34 releases the pin 16 which has been inserted in the work and the pin 13 rides out of the top of the vertical groove 14 into an inclined groove 15 to index the head during this stroke. The bracket 18 is guided by a vertical stud 37 attached to the machine frame 2 and carrying a nut 38<1> to limit the upward movement of the rack. The pins 16 are supplied to the pipe 22 from a rotatable magazine 25 having vertical tubes 26 which may be brought in turn over the pipe 22 to discharge therein and then rotated slightly to close the end of the pipe against air pressure by the body of the magazine. To insert a pin 16 in the other end of the work, the latter is reversed vertically and horizontally on its support 30 and the previously inserted pin enters a recess 4 in the support.
Patent GB-447451-A (GB)
Title: Process for treating antimonial lead
IPC: C22B30/02
Filed: 1935-05-24
Abstract: A process for treating alloys of lead and antimony containing at least 20 per cent of antimony comprises forming a molten bath of the alloy, simultaneously agitating and lowering the temperature thereof and thereby concentrating the antimony as a dross which is treated with a drying agent to yield a dross containing 65-80 per cent of antimony.  The original temperature of the bath is within the range of 750-800 DEG  F. and is lowered at the rate of 15-25 DEG  F. per hour to 550-525 DEG  F. at which temperature the drying-agent, which may be petroleum coke or rosin or both, is added.  The dross is removed by shovelling and the temperature of the bath lowered to 490 DEG  F. when a crust separates containing the excess of antimony over the eutectic ratios of lead and antimony (13 per cent of antimony). The eutectic metal is removed and a fresh charge mixed with the crust.  In addition to antimony and lead, the crude metal may contain tin, copper and arsenic.  In an example, the crude metal comprised 30-35 per cent of antimony, 1-2 per cent of copper, 1-2 per cent of arsenic, 0,2 per cent of tin and 0,2 per cent of tellurium and nickel, the balance being lead.  Tin and arsenic may be removed by heating to approximately 1000 DEG  F. under oxidizing conditions. Alloys poor in antimony may be treated, as by smelting, to increase the antimony content before carrying out the present process. Specification 381,955 is referred to.

Title: Tyre grinding apparatus and method
IPC: B23Q15/00
Filed: 1973-03-29
Abstract: 1421247 Grinding tyres GENERAL TIRE & RUBBER CO 29 March 1973 [5 April 1972] 15218/73 Heading B3D [Also in Division G3] For achieving uniformity of automobile tyre characteristics a tyre 12 is rotated in contact with a load wheel 10 and the force reaction between the tyre and wheel is sensed, the shoulders of the tyre being ground until the force reaction lies within predetermined limits and until a harmonic of the force variation lies within predetermined limits. The grinding may be first performed under control of the force reaction until such reaction lies within the predetermined limits at which time the control is automatically switched to the harmonic of the force variation, or vice-versa. As shown, a load cell 14 converts the force variation to an analogue signal which, after suitable processing is applied to servo-amplifiers 38, 40 for the grinding means via a delay unit 42. The first harmonic of this analogue signal is derived from an amplifier 60 and an integrator 62, whose output signal can also be applied to the servo amplifiers via the delay unit. For control by the composite force variation, the processed analogue signal is applied to a peak detector 22 whose output is connected to a storage device 24. The output of the storage device is compared in upper and lower limit comparators 32, 34 with reference signals presenting the predetermined limits. The lower limit comparator output is applied to a comparator 80, see also Fig. 2 (not shown), which operates a relay 82 to disconnect the analogue signal from the servo-amplifiers 38, 40 and connect the first harmonic signal to the servoamplifiers. To determine when the first harmonic signal lies within predetermined limits, the first harmonic signal is also derived from an amplifier 44 and an integrator 46 whose output is applied, via a storage device 49 to upper and lower limit comparators 54, 56. The outputs of all the comparators 32, 34, 54, 56 are applied to a grind comparator 72 which operates a relay 74 to retract the grinding means.
