Title: Improvements in and relating to the manufacture of blown glass articles
Inventor: OLSON RALPH HARVARD
IPC: C03B9/38
Filed: 1959-10-27
Abstract: 930,316. Glass-blowing machines. OWENSILLINOIS GLASS CO. Oct. 27, 1959, No. 36302/59. Class 56. When forming a blown glass article from a parison formed in a parison mould and then transferred to a blow mould, the distribution of glass in the walls of the article is controlled by applying a gaseous cooling medium to the parison at its place of formation from diametrically opposite sides in a circumferentially encompassing pattern extending over a selected vertically defined external surface area of the parison, the application of the cooling medium being continued during at least part of the transfer of the parison to the blow mould. In an Owens-type machine, Fig. 4, the blank head 50 carries pins 131, 132 for locating a neck mould 51 and below them a blank mould or, subsequently, a blow mould 74. The pins are hollow and supplied with air which emerges through holes 150 to cool a selected portion of the parison determined by the number and distribution of the holes and the direction in which they are formed in the pins 131, 132. In an arrangement, such as shown, using a double mould, a central hollow pin, located between the two parisons, is also used. No air can reach the parison when either mould is closed as it then encloses the pin. The air supply may additionally be controlled by valves, one for each head of the machine on the rotating structure, operated by a cam on the stationary part. The air from each valve is fed to a distribution box in which adjustable needle valves control the relative strength of the blasts supplied to the various locating pins. Cooling air may also supply to the inside of the parison. Part of a press and blow machine is shown in Fig. 12. The parison mould 172 is charged with molten glass and moved up by a cylinder 176 to engage a neck mould 171 located on a head 170 by pins 131, 132 while a plunger 173 descends and forces the glass to the neck mould. The parison mould 172 is then removed and replaced by-the blow mould 177 actuated by a cylinder 178. As before, the pins 131, 132 are hollow and air is fed to them. They also locate both the parison and blow moulds. In the press and blow machine shown in Fig. 13 the head 187 carries pins which locate a neck mould 185 and a blank mould which is charged through a hole 182. This hole is then closed by a plunger 183 while a plunger 184 moves up into the mould. The plungers and the blank mould are removed while the head, the neck mould and the parison are swung about the pivot 189 to engage the blow mould 190. As before, an air blast, supplied to the hollow pins 131, 132 acts on the parison during the transfer. U.S.A. Specification 1,185,687 is referred to.

Patent GB-523084-A (GB)
Title: Improvements in or relating to clutch systems
IPC: F16D67/02
Filed: 1938-12-23
Abstract: 523,084. Variable-speed gearing. BORG-WARNER CORPORATION. Dec. 23, 1938, No. 37516. Convention date, Feb. 23. [Class 80 (ii)] The main clutch of a motor vehicle is normally controlled by speed-responsive means so as to be disengaged below a predetermined speed, while means controlled by the gear selector mechanism overrides the speedresponsive control so as to maintain the clutch engaged at all speeds when intermediate or high gear is engaged, and the application of the vehicle brakes renders the overriding control ineffective and restores the speed-responsive control. The speed-responsive means may be internal or external to the clutch. A centrifugal clutch 41 is shown, including a reaction plate 7 which is loaded by springs 6 and which is under the control, through levers 14, of a slidable collar 15. With the collar positioned as shown, the clutch operates automatically ; if the collar is allowed to move to the right, the springs 6 act to maintain clutch engagement at all speeds ; if the collar is moved to the left, the clutch is disengaged at all speeds. The collar is controlled by a fork 23 on a shaft 22 having an arm 26 carrying adjustable screws 29 which coact respectively with arms 31 and 66 loose on the shaft 22. The arm 31 is connected to the usual clutch pedal 33, depression of which thus disengages the clutch at all speeds. The arm 66 is urged anti-clockwise by a spring 64 towards an adjustable stop 68 and tends to maintain the collar 15 in the position shown. The arm 66 is linked to a piston 63 movable in a cylinder 57. A piston valve 54 is operated through a spring 76 by the brake pedal 74 so that, when the latter is released, a pressurefluid supply pipe 49 is connected to the cylinder 57, while when the pedal is depressed (as shown), the cylinder is connected to a drain 58. The gear selector mechanism shown comprises a manually-operable lever 43 controlling a distributing valve 45 for pressure fluid supplied by a pump 46, the valve also serving to supply pressure fluid to the pipe 49 only when intermediate or high gear is engaged. The gear control may, however, be automatic. Thus, when intermediate or high gear is engaged, the piston 63 is moved to the right so as to allow the collar 15 to move to the right so that the clutch is maintained in engagement at all speeds. On depressing the pedal 74, however, valve 54 is moved to cut off the supply from the pipe 49 and to open the cylinder 57 to the drain, whereby the spring 64 returns the collar 15 to the position shown. Alternatively, the clutch may be operated by a vacuum servo controlled by a valve which is operated by the accelerator pedal and which, when the accelerator is released, is operated by a speed-responsive device, the latter being locked when intermediate or high gear is engaged but being released upon application of the brakes.
