Title: Improvements in or relating to processes for agglomerating alumina
IPC: B01J21/16
Filed: 1954-03-23
Abstract: In a process for agglomerating alumina, a trihydrate of alumina, preferably bayerite, is dehydrated at temperatures between 160 DEG and 500 DEG C. so that the water is removed immediately it is driven from the alumina, e.g. by vacuum distillation or by heat and suspension in the hot gas.  The product may then be ground to required size, is shaped by mixing with water, allowed to harden in amoist atmosphere between 20 DEG -150 DEG C. to allow partial rehydration of aluminium into bayerite and then subjected to further treatment at temperatures between 250-600 DEG C. to effect at least partial dehydration.

Abstract: 537,730. Electric control systems. IGRANIC ELECTRIC CO., Ltd. May 14, 1940, No. 8646. Convention date, May 27, 1938. [Class 40 (i)] [Also in Group XXXV] A self balanced Wheatstone-bridge system for controlling the brightness of lamps is arranged to avoid over-regulation of lamp current due to the temperature co-efficient of resistance of the filaments and the time lag of resistance variations. In Fig. 1, an alternating current bridge comprises a control potentiometer 17 and a variable auto-transformer 3 feeding the lamps 2, the tapping of the auto-transformer being varied by motor 6 controlled by a normally balanced relay 8. The windings 10, 11 of the relay tend to keep its armature neutral and windings 12, 13 aid and oppose the corresponding windings 10, 11 or vice-versa depending on the direction of bridge unbalance. Variation of the load 2 due to resistance variations - has substantially no effect on the secondary voltage of the auto-transformer. In the modification shown in Fig. 2, control is effected over direct current lines, the lamps 22 being fed from a motor-controlled variable resistance 23 in an A.C. circuit. The control circuit of relay 8 comprises a transformer 29 having its primary 28 in series with one or more of the lamps or equivalent devices (in parallel) so that the transformer output voltage is dependent on lamp current. The output of 29 is rectified, smoothed if necessary, and applied across resistance 33 to the circuit of relay windings 12, 13.

Title: Improvements in or relating to a method of knitting combination full-fashioned stocking blanks and a straight bar knitting machine for carrying out said method
IPC: D04B11/28
Filed: 1939-03-20
Abstract: 526,570. Knitting. LAMBACH, F. March 20, 1939, No. 8882. Convention date, March 26, 1938. [Class 74 (ii)] Relates to the method of knitting stocking blanks on a straight bar knitting machine wherein the foot is knitted directly on to the leg and the first loop courses of the sole portions, beginning at the heel corners, are inter-knitted with the heels by transferring loops to the selvage needles that knit the heels 440, Fig. 17, on to the high heels 13, 14. The last loop courses of the two high heels and the first loop courses of the two sole portions 15, 16 are put on the needles in such a manner that the two high heels 13, 14 are adjacent and towards the centre. A single continuous heel is made by one carrier 480. In another form the high heels are topped on to two inner spaced sets of needles 500, Fig. 10, and the soles to outer sets 500', the selvage loops of the high heels being spaced apart a distance c. The heel knitting then proceeds on the high heel needles, while the loops held by inactive needles are transferred inwardly to the extent of one to four needles at every one to three courses. The heels are knitted by means of two carriers 48 and two slur cocks 51, 51<SP>1</SP>, Fig. 11, moving in opposite directions on different levels. The sinker jacks 52 have cam surfaces 53, 53<SP>1</SP> and recesses 54, 54<SP>1</SP> so arranged that each slur cock operates its own sinkers. For rendering the sole needles inactive, the presser has a divided edge, there being fixed a centre portion 55 and movable side portions 56, secured at their lower ends to a holder 59. A cam 74 slides the holder 59 in and out of action by means of intermediate connections 69, 66, 64. A course or more may be knitted on sole and high heel portions before - beginning the heel. An attachment for controlling narrowing fingers 46 comprises a supporting rod 111, Fig. 28, urged by a spring 114 against a plate 115. A body 116 slidable on shaft 118 and carrying the plate 115 is urged by a spring 119 against a body 120. Spring 119 also holds a pin 123 on the body 120 in contact with a stepped segment 124. To change the basic position of the narrowing finger the body 120 is moved clear of the segment 124 by a rod 131 acting on a cam arm 132. The segment 124 is readjusted by the action of a pattern chain 141 on a rack 138 gearing with teeth 137. For transferring loops, a stepped segment 127 is operated to displace the narrowing finger a distance of one to four needles.

Abstract: 453,883. Endless belt conveyers. RUSSELL, E. D. B., Manor House, Rainham, Kent. March 21, 1935, No. 8892. [Class 78 (i)] [See also Group XVIII] A transportable machine for filling sacks, bags, or the like with granular or powdered material or the like comprises an endless-belt or like motor-driven conveyer-elevator 15 mounted on a carriage 1 and provided with a shoe 18 whereby the conveyer nose can be forced into a pile of the material or alternatively be brought below a bin or like outlet. A packer 25 and an aircompressor 27 are driven by the conveyer motor 19, the compressed air being discharged into the packer to ensure that the material, especially when in powder form, is kept in a turbulent state. The delivery orifice of the packer leads by a flexible sleeve 29 to a spout 30 suitable for " valvefilling." Below the spout 30 is located a tip-pan 31 pivoted to a cradle 32 carried by parallel arms 35 and suspended by an adjustably supported spring balance 34. An operator seated at 39 takes a sack from a table 42, pushes the spout 30 through the sack valve or flap, adjusts the sack on the pan 31, and operates a lever 40 to open a slide valve 43. When the sack is sufficiently full, as indicated by the balance 34, the valve 43 is closed and the pan 31 is tilted about its trunnions 41 to throw the sack down. Surplus material beyond the capacity of the hopper 22 passes over to the down leg of the conveyer elevator and so back to the intake. The carriage 1 rides on four wheels 2, 3, of which the front wheels 2 can be manually rotated by levers 6 and pawls 5 acting on toothed wheels 4 fixed to the wheels 2. The wheels 3 are mounted in horns 8 the radius arms 12 of which are jointed together for uniform turning when steered by handles 14.

Title: Improvements in differential gears

Abstract: 706,989. Differential gearing. SAMPIETRA, A. C. April 1, 1952 [April 18, 1951], No. 9073/51, Class 80 (2)  Differential gearing, comprising an input and two output elements, is provided with means responsive to relative rotation between the output elements to tend to oppose such relative rotation, these means consisting of yieldable material which is deformed upon relative rotation between the said output elements. As shown, drive from a shaft 31 is transmitted to a crown wheel 13 secured to a differential cage 1, in which are mounted bevel planets 15, 16 meshing sun gears 20, 21 keyed to output shafts 4, 5. Elliptical rings 26, 26' are also keyed to the output shafts and are surrounded by correspondingly elliptically shaped rings 27 secured to the cage 1, the spaces between the rings 26<SP>1</SP>, 27 being filled by a deformable element 28 made from a yieldable and resilient material such as rubber. When one output shaft rotates faster than the other, the rings 26<SP>1</SP>, 27 rotate relatively to each other and the yieldable element 28 is accordingly compressed and allowed to expand as the space between them varies, so that a torque is produced which restrains the rotation of the faster output shaft and assists the rotation of the slower. The magnitude of this torque varies in accordance with the relative rotational speeds of the output shafts. As a modification, each deformable element is either mounted between cylindrical surfaces eccentric to each other or between a cylindrical surface and an elliptical surface.
