Title: Improved method and apparatus for forming and delivering glass
IPC: C03B7/14
Filed: 1963-07-01
Abstract: <PICT:1048927/C1/1> <PICT:1048927/C1/2> <PICT:1048927/C1/3> In a method of forming and delivering glass, a charge of the molten material is severed from a downwardly directed stream and immediately gripped and pressed by laterally moving male and female formers, the charge then being retained in the female former which is moved laterally and rotated to bring the charge into an overlying relationship with a continuously moving head on to which it is deposited, the female former finally being returned to the forming station.  In operation a male former 32 and female former 33 are located just below a pair of shears 31.  As a gob G is sheared, the formers are moved towards each other by the respective actions of their pistons and cylinders 41, 42 and 52, 53, thus catching the gob and pressing it.  As they move together vacuum is applied to the female former cavity 111 through orifices 111a  and 111b ; to ensure a firm pressure the piston rod 40 of the male former 42 acts against a spring 46. The formers are then drawn apart by reversing the action of their cylinders, the charge P being held in the female former by suction.  When the female former 33 has been retracted it is rotated downwardly through 90 degrees by means of hydraulically operated pushing rods 82, 83, Fig. 9 (not shown), acting against a yoke 80 attached to a rotatable supporting rod 70 to which the female former is attached, said rod 71 being mounted within a movable arm 71.  The female former is now located over an inverted spindle S of a continuously rotating machine, e.g. a Westlake machine.  In order that the charge may be deposited upon the moving spindle, the arm 71 is rotated about a vertical axis for about 2 1/4 degrees of machine movement at the same speed as the machine, and also the piston and cylinder 52, 53 of the female former is operated to move the charge closer to the spindle.  The vacuum is then turned off and air pressure is briefly applied to release the charge.  The female former 33 is then retracted upwardly, rotated upwardly through 90 degrees and swung back horizontally to the initial position.  The charge P having been deposited upon the sdindle S is clamped peripherally by arcuate clamping elements 121, Figs. 16-20 (not shown), and a plunger 123 with a concave surface is moved upwardly to bring its periphery 124 into contact with the periphery of the underside of the charge for cooling purposes.  The formers are cooled by passing a liquid through tubes 110a  therein. The operation of the delivery and forming mechanisms is controlled by a series of timer drums actuating the hydraulic circuit described with reference to Fig. 15 (not shown).

Title: Improvements in or relating to underwater lowering devices
IPC: B63C7/16
Filed: 1960-07-28
Abstract: 955,598. Hooks. WESTERN ELECTRIC CO. Inc. July 28, 1960 [July 29, 1959], No. 26302/60. Heading. F2H. A device for lowering a cable to the bed of the ocean comprises a hook for holding the cable, means for opening the hook to release the cable, control means for operating the releasing means at the required depth, signalling means for indicating when the releasing means has been actuated, and an emergency device for operating the releasing means if the latter fails to operate normally. The lowering device comprises a body 1, having a hook 6 which supports a cradle 9 for a cable 11, and is lowered from a ship by a rope 4 secured to a swivel 2. A loop 12 surrounding the body 1 has arms 13 passing through elongated slots 14 in the body, the arms being adapted to operate a catch 7 to release the cable 11 when the hoop engages the sea bed. The releasing device comprises a bell-crank 30 pivoted at 31, linked to a boss 27 on the arms 13, and carrying a spring-urged lever 32 which engages a tooth 42 on a bar 18, so that as the arms 13 move or tilt upwardly the bar 18 is moved to the left and actuates a toggle 35, 36, which lifts the catch 7 to release the hook 6. To prevent the bar 18 from being moved to the left before the device reaches the required depth, a bar 48 separates the lever 32 from the tooth 42, this bar only being moved to the right when the required depth is reached by the hydrostatic pressure of the water. A bellows 43 secured to the bar 48 is in contact with the water which enters a chamber 46 through a passage 16. As the required depth and pressure is reached, the bellows is compressed and the bar 48 moves away from the lever 32, which is then spring-urged into contact with the tooth 42, and the releasing device is in its operating position. To indicate when the cable is released a glass ball 51, secured to the body 1 by a nut 19, is imploded by a plunger 53 which is actuated when the link 36 is moved upwardly, and the signal thus produced can be picked up by a hydrophone on the ship. If the releasing device fails to operate, a low frequency signal is transmitted from the ship, is picked up by a hydrophone 17 and converted to electrical energy, which is applied to a relay 55 controlling a circuit leading from a battery 56 to a solenoid 57. The armature 58 of the solenoid is secured to an extension 59 of the bar 18, and moves to the left, thus moving the toggle and the catch 7 to the cable releasing position. The implosive signalling device may be replaced by an explosive charge, or the plunger 53 may be designed to release a buoyant device which would rise to the surface of the water. The bellows 43 may be replaced by a temperature sensitive device, and the disarming device for the releasing mechanism, and/or the emergency releasing device may be designed to use timing mechanisms or water soluble materials for initiating the operations.

Title: Improved method of reducing thickness variations in sheet material
Inventor: HOLMAN HERBERT EDWARD
IPC: B21B3/00
Filed: 1954-09-15
Abstract: One or each of a pair of rollers is reduced in diameter between its ends to form an annular recess so that, when the ends of the rollers are urged into contact, a gap remains between them.  The rollers are used to reduce thickness variations in sheet material, particularly thermoplastic material such as polyvinyl chloride, which is unwound from a roll, passed through a heating zone, drawn between the rollers, cooled and wound on another roll.  The speed of rotation of, and pressure between, the rollers are suitable for smoothing the sheet to a constant thickness equal to the gap. Cooling water may be passed through the rollers.  The invention has particular application to plastic sheet which is to be coated with magnetisable material, but is also applicable to the rolling of ductile metal sheet.
