Abstract: 781,949. Variable-speed gear. AUSTIN MOTOR CO., Ltd., and WEAVING, J. H. Oct. 17, 1955 [Oct. 27, 1954], No. 30942/54. Class 80 (2). In an automatic transmission for a motor vehicle the road wheels are connected, e.g. by Hooke's joints, to the shafts 23, 24 of a bevel differential gear whose planet carrier 20 is coupled by a manually-operable dog-clutch 25 to one or other of oppositely-rotating bevel crown wheels 17, 18 which are continuously driven by the output pinion 16 of a torque-converter 10-13-14. The clutch sleeve 25 is moved by a fork on a slidable shaft 40 actuated by a control (not shown) to give forward, neutral and reverse. A synchronizing sleeve 34 splined on the planet carrier 20 is formed with conical ends engageable with conical faces on the wheels 17, 18 and is coupled to the sleeve 25 by splines and by a spring ring 43 co-operating with three grooves on the sleeve 25. As the shaft 40 is moved from the neutral position shown to give a forward or reverse drive, the synchronizing conical surfaces come into frictional engagement and continued movement of the shaft overcomes the spring 43 to allow the dog teeth on sleeve 25 to engage those on the appropriate bevel wheel. The shafts 23, 24 may carry discs 44, 45 for the vehicle brakes. The driving and reaction elements 10, 14-of the torque-converter are rotatably mounted. on a fixed hollow shaft 30, while the driven element 13 is carried by the pinion shaft 15 which has bearings within the shaft 30 and in the engine flywheel 12, to which the element 10 is bolted. The reaction element 14 has a freewheel connection with the fixed shaft 30.

Title: Bucket elevator
IPC: B65G17/36
Filed: 1950-12-28
Abstract: 683,733. Endless bucket elevators. TRANSEAU, S. T. Dec. 28, 1950. No. 31483/50. Class 78 (i). An endless bucket elevator comprises a single endless strand to which laterally spaced rows of buckets are so secured as to leave a space or spaces between the rows for a snubbing wheel or wheels to deflect the strand on the discharge side inwardly below the head wheel or wheels whereby the material is discharged onto a shoot extending in under the head wheel or wheels. In one form, Fig. 3, a single endless bucket-carrying chain 20 is passed over head and foot sprockets 23, 21, and a snubbing sprocket 27 causes the chain to bend back under the head sprocket to ensure complete discharge of material carried from an inlet 42 by the buckets into outlet shoot 25 which straddles the sprocket 27. In order to avoid the snubbing sprocket the buckets 53 are arranged in two side-by-side rows Fig. 7. Shaft 36 of the head sprocket is driven in any suitable manner. The bucket carrying links of the chain consist of side links 46, 48 each having a lateral flange 51 drilled to receive bucket fastening bolts or rivets 56. The buckets are preferably formed with lower and upper interlocking flanges 61, 62, Fig. 12, co-operating with surfaces 58, 60 of the flanges 51, or with only. a lower flange as in Fig. 7. To minirnise spilling from the buckets the head sprocket is formed upon a drum provided with side flanges so as to form a trough directing spilt material into the discharge outlet. Owing to the chain being wrapped 225 degrees around the head wheel the sprocket teeth on this and on the snub wheel may be replaced by plain rims. Snub wheel 27 may be placed lower and shoot 25 less under the head wheel so that wheel 27 is entirely screened from falling material by the shoot. The foot wheel 21 has sprocket teeth 67 engaging the chain, Fig. 9, and axial flanges 64 on which rest ribs 62 which strengthen the flanges 51 and also protect the chain from wear. Wheel 21 may be provided additionally with radial flanges 68 for steadying the buckets 53. In a modification, Fig. 14, the endless chain is replaced by a flat endless belt on which are mounted three or more rows of buckets 75, 76, 77. The head and foot wheels are plain drums while the snubbing wheel consists of a number of discs 81 ... 84 engaging the belt between the rows of brackets, and being mounted on a common shaft 72, the shoot 25 straddling each disc.

Title: Improvements in and relating to the production of scales photographically
Inventor: DYMOTT EDWIN REGINALD
IPC: G03B17/24
Filed: 1957-10-10
Abstract: 897,297. Micro-photographic production of scales. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 10, 1958 [Oct. 10, 1957; March 31, 1958], Nos. 31726/57 and 10251/58. Class 98(1). In a method of making scales, for example precision coded scales, from an original by micro-photography, a rigid light-sensitised scale receiving support and a sprocket driven strip carrying the original are both continuously moved throughout exposure so that the image of the original projected on to the support does not move relatively thereto and the ratio of reduction is at least 20:1. As shown, a kinematograph film is driven, by means of a sprocket, through a cylindrically curved projection gate (Fig. 3, not shown) at which it is supported by its margins and illuminated by a ribbon filament lamp 15 and a moderately well corrected photographic objective 16 as condenser. A well corrected photographic objective 17 forms an image on a high resolution photographic emulsion coated on glass disc 13. The disc is rotated on a turn-table 11 to produce a circular scale as the film is continuously fed through the projection gate. To achieve the required precision in the motion-reducing gear in gear transmission between the sprocket and the turn-table, the turn-table and worm drive therefor may be parts of a conventional circular dividing engine. The sprocket is driven by spur and spiral bevel gears from a constant speed servo or synchronous electric motor (Fig. 2, not shown). Two spur wheels may be changed to alter the drive ratio. Micrometer screw 23 adjusts objective carriage 21 radially and may be continuously operated to produce a spiral scale. In another form (Fig. 4, not shown) a precision screw-threaded bar drives a photographic plate rectilinearly to produce a linear scale. Limit switches are provided at the end of each linear traverse to control the electric motor. The edge of a masking strip moving with the film on opaque leader or trailer strips of the film ensure that the end points of the scale are clearly defined. The original may be made on the flexible strip either photographically, by drawing, or by punching holes in an opaque strip. The apparatus may be used to produce radial optical gratings. The scales obtained may be reproduced by contact printing.

The N 2  and/or CO which are desorbed on pressure reduction and any remaining hydrogen pass in reverse flow from the second zone to the inlet and act as scavenging gas to desorb the gases adsorbed in the first zone. The adsorber may then be prepared for re-use by re-pressurisation to atmospheric pressure with hydrogen.
