Title: Improved method of and apparatus for tempering glass articles
IPC: C03B27/02
Filed: 1935-01-17
Abstract: 450,464. Tempering glass. PILKING- TON BROS., Ltd., 703, Tower Building, Water Street, Liverpool, and MITFORD, J. B., 425, Prescot Road, St. Helens, Lancashire. Jan. 17, 1935, No. 1573. [Class 56] In a method of tempering articles of non- uniform thickness by means of jets of a cooling medium such as air or steam, the thinner portions are subjected to a lower average rate of cooling than the thicker portions (other than projecting thick portions). This may be done by arranging that a smaller amount of cooling medium per unit of time and of area reaches the thinner than the thicker portions throughout the cooling operation or by delaying the start of cooling of the thinner portions. In the arrangements shown, the article 1 is rotated between frames formed by pipes 7 carrying the cooling fluid and furnished with jets. Alternatively the frames may be rotated and the article remain stationary. Where the article is not symmetrical about a central axis, the relative motion may be oscillatory instead of rotary. In the arrangements shown in Figs. 3 and 5, the proper rates of cooling are secured by the number and arrangement of the jets in the cooling frames. The article 1 in Fig. 5 has thick projecting portions 18, 25 which are cooled less rapidly than the rest of the article with the help of wire gauze or the like 20 and a suitable spacing of holes in the cooling frame. In the arrangement shown in Fig. 4, the supply of fluid to different parts of the cooling frame is separately controlled as by the valves 16, 17 so that cooling of the thin central and thinner portions of the article can be delayed.

Title: Improvements in and relating to brakes for vehicles
IPC: B60T8/32
Filed: 1963-01-14
Abstract: 1,023,861. Compressed air brakes. OERLIKON-BUHRLE HOLDING A.G. Jan. 14, 1963 [Jan. 22, 1962], No. 1603/63. Heading F2F.  A speed-responsive change-over device for rail vehicle brakes, the device comprising a tachometric generator 48, the voltage from which actuates, through an adjustable attenuator, an electromagnetioally controlled brake booster valve 35, two outputs from the attenuator being variable independently of each other. The valve circuit is subjected to one or other of the attenuator outputs by a switching member which is operated simultaneously with the actuation of the valve 35. In the construction shown, a triple valve 8 functions under the influence of the pressures in the brake pipe 6 and reservoir 9, the triple valve controlling the pressure in a chamber 11 of a relay valve 12. A chamber 23 of the relay valve is connected through a spring-loaded brake valve 22 to an auxiliary reservoir 14, to the brake cylinder 25, to a switch 28, through valve stem 21 to atmosphere at 29 and through valve 35 to a third relay valve chamber 32. The attenuator comprises either two resistors each variably tapped (Fig. 2, not shown) on one resistor variably tapped at two points (Fig. 3, not shown), the outputs being calibrated, as on scale 59, to correspond with the speeds at which the valve 35 is to be energized and de-energized respectively. The output of the tachometer may be alternating or direct, in the former case the output being rectified before the attenuating part of the circuit. When the brake is applied through the pressurization of chamber 11 and the subsequent closing and opening of valve stem 21 and valve 22, switch 28 is closed. With the speed below that required for booster braking relay, valve 12 moves into the selflapping position. If, however, the speed is above that predetermined, a relay 64 (Fig. 2, not shown) is triggered from one output of the attenuator to actuate the valve 35 which cuts off the brake cylinder from chamber 32 and a flexible diaphragm 19, these latter being vented to air through the valve at 41. Thus the pressure in chamber 11, that is against diaphragm 18, becomes dominent again as the brake cylinder pressure is acting on a small area diaphragm 20, the brake valve 22 being opened again. The speed at which the boosting is discontinued is governed by the second output of the attenuator which is switched into circuit also by relay 64.

Abstract: 262,290. Dicker, S. G. S., (Owens Bottle Co.). Jan. 23, 1926. Blowing. - Relates to a forming machine comprising a rotary carriage and moulds which are carried by hollow arms pivoted on hollow shafts, and consists in using the shafts and arms as air passages through which air is supplied to cool the moulds. Devices such as nozzles are provided to direct the air from the arms against the mould sections, and manuallyadjustable valves or dampers are provided in each hollow shaft, and in each nozzle, for controlling the supply of air. Fig. 1 shows the invention applied to a bottle-blowing machine of the Graham type in which the rotating mould carriage comprises an upper section 18 and a lower section 16 that carry the blank moulds 19 and finishing moulds 17 respectively. The sections 16, 18 are carried by vertical standards which permit them to be adjusted relatively to one another. Each ring mould 39 is mounted on a horizontal axle 40, and is rotated, to swing a parison from the blank mould to the finishing mould, by means of a gear segment 43 operated by stationary cams. The bottom of a finishing mould is hollow and comprises a mould plate 44 with a cylindrical extension 45. This extension slides into a cylindrical carrier 46 and is held in place by a spring detent to permit of easy replacement. The carrier 46 is mounted on a horizontal rock shaft 51 on a frame 52, so that the mould can be tilted to discharge the finished bottles. Cooling moulds.-Air is supplied to a chamber 59 in the lower section 16 of the mould carriage, and a port 61 connects this chamber with another chamber 62 in the hollow frame 52 and a passage-way 63 formed in the carrier 46. Air is thus admitted to the interior of the bottom plate 44 and is discharged through'ports 64. The air thus circulating in contact with the bottom plate is controlled by a manually-adjustable valve or damper 45 in the passage-way 63. Air for cooling the finishing moulds is supplied from the chamber 59 to the hollow shaft 26 on which the mould sect-ions 17 are pivoted, and manuallyadjustable valves 69 control the amount of air which enters the hollow arms 25 of the mould sections. The air passes from the arms 25 to nozzles which direct it against the mould sections, and the supply of air to each nozzle is independently controlled. Air for cooling the blank moulds is conducted from the chamber 59 through telescopic pipes 77 to a passage-way 78 and thence into the hollow shaft on which the mould sections are pivoted. The air then issues from nozzles which direct it on to the moulds. Specification 192,347 is referred to.
