Abstract: 1,238,325. Drying compressed gas. AIR TECHNIQUES Inc. 2 Aug., 1968, No. 37119/ 68. Heading B1L. Moist compressed gas, particularly air, from compressor 10 is passed by line 14 through separator 18 where droplets are removed, and thence through drying chamber 26 packed with desiccant, e.g. silica gel, activated alumina, molecular sieve. The major part of the effluent dry gas is then passed by line 38 to tank 46, while a minor part is passed by adjustable valve 68 and unidirectional checkvalve 84 to secondary tank 92. When pressure in tank 46 reaches a predetermined valve, switch 52 switches off motor 54 driving compressor 10 until sufficient gas has been removed for use through line 48 for the pressure to have fallen to a second predetermined valve at which switch 52 switches motor 54 on again. During the period during which motor 54 is inoperative, compressed air in chamber 26 vents to atmosphere through separator 18 carrying moisture from chamber 26 with it, check valve 40 preventing decompression of tank 46. Air also flows back from secondary tank 92 through pressure regulating valve 106, which is set so that the volume of air effluent therefrom is the same as the volume of compressed air which has passed through drying chamber 26 since the previous cycle. This dry return stream flows through chamber 26, regenerating it, and is vented through separator 18, vent valve 58 being controlled by switch 52. Before the system is brought into use, valve 120 is opened so that compressed gas in tank 46 passes along line 116 to supplement the gas in tank 92 being refluxed through chamber 26; this ensures that desiccant 28 is completely dry at the outset. Valve 120 is then closed.

Abstract: 1,250,990. Variable-speed gear. SOC. ANON. FRANCAISE DU FERODO. 27 Aug., 1969 [29 Aug., 1968], No. 42626/69. Heading F2D. To extend the range of ratios and/or reduce the power and size requirements of a steplesslyvariable and reversible hydrostatic or mechanical gear V, the gear is arranged to connect the input shaft P to one element A, e.g. sun 15, of a four-element planet train, two other elements B, D of which are connected alternatively to input P or, in some cases to a fixed frame, whilst the fourth element C is connected to the final output R. The range may be further extended by similar gear trains between C and output, in which case forward and reverse ratios are obtained, or, as in Fig. 2 a supplementary output bevel reverse gear is provided. The torque-split planet gear shown in Figs. 1 and 2 comprises two equal sun-ring trains having a first sun 15 as the gear input element A; connected first carrier 17 and second ring 20 as element B; connected first ring 16 and second carrier 21 as final output element C; and second sun 19 as element D. Disc clutches E B , E D  connect the elements B, D respectively to the gear input A. A pump-motor hydrostatic unit U 1 , U 2 , providing forward, zero, and reverse ratios, is driven by the main input P through a meshing gear pair 24, 25, and drives the gear input A through a similar pair 27, 26. In operation, with the clutch E D  engaged, the full stepless range is covered by taking the variable gear U 1 , U 2  from maximum reverse ratio to zero; changing over to clutch E B , and adjusting the variable gear to maximum forward, giving equal ratio point, and then adjusting the gear down through zero to maximum reverse. This gives an overall stepless range of 0À414 to 1À828, the maximum power taken by the variable gear being 41À4% of the input power, with a gear train value of 2À414 for each train (tooth numbers are specified). Reverse is provided by a separate series bevel train 30. In Figs. 4 and 5, not shown, a further clutchbrake two-speed planet gear is arranged between the main input P and the clutches E B , E D , which extends the overall ratio range to 0À33 to 2À50 with a maximum power requirement for the variable gear of 33% input maximum. In Figs. 6 and 7, not shown, an additional four-element gear, similar to that of Fig. 2, is arranged between the output C (Fig. 2) and the final output, this gear having a released or braked element D, and a released, clutched or braked element B. Ratio range is 1À43 to 2À43 forward, 0À43 to 1À43 reverse, with a variablegear taking 33% maximum input power. A further additional gear may be similarly arranged after the first additional gear.
