Title: Improved differential driving mechanism
Filed: 1934-11-05
Abstract: 432,673. Differential gearing. WALES, H. N., 19, Carson Street, Kew, Victoria, Australia. Nov. 5, 1934, No. 31773. Convention date, Aug. 4. [Class 80 (ii)] A differential drive suitable for motor vehicles which is self-locking or irreversible, or reversible to any desired degree, and which will prevent single wheel spin, has an annular driving element with which co-operate bars rotatable with but slidable relatively to said element, the bars being provided with teeth or projections adapted to engage sinuous or zigzag grooves around the peripheries of two separate collars fast with the respective axles. A cylindrical housing 2 is driven through a crown wheel 3 and has on its inner periphery a number of longitudinal slideways 8 accommodating two series of drive-transmitting bars 9a, 9b, Figs. 1, 5, each bar having two teeth 11, Fig. 9, slidably engaging grooves 14, 16, 17 in collars 12, 13 fast on the axles 6, 7 respectively. The collar 12 has a single groove, but two grooves are formed in the collar 13, the grooves being oppositely disposed. The bars are alternately long and short, the teeth thereon are diamond-shaped and are spaced apart a distance equal respectively to the longitudinal distance between the groove 14, Fig. 5, and parts of the grooves 16, 17 parallel thereto when the junctions of the grooves are in line. With a vehicle travelling on a straight course, the assembly will rotate as a unit, the bars 9a, 9<b> being unable to move axially as the teeth 11 of either or both are engaged in oppositely inclined portions of the grooves. Upon deviation from a straight course, relative movement of the shafts is permitted by sliding of the teeth in the grooves and axial reciprocation of the bars in the housing 2. The mechanism may be rendered irreversible to avoid single wheel spin, or reversible to a limited extent, by suitably selecting the angle which the sections of the grooves make with a plane normal to the axis of the shafts. The side faces of the grooves and bars may be parallel or inclined.

Patent GB-837611-A (GB)
Title: Improvements in or relating to the manufacture of soap
Inventor: FINSBERG ARNE
IPC: C11D13/04
Filed: 1956-10-19
Abstract: A process for washing soap comprises (a) continuously supplying soap and fresh lye or nigre to a vessel in which they are intimately mixed; (b) separating the soap from the lye or nigre, and then (c) recycling and remixing with the soap a portion of the separated lye or nigre which is at least equal in weight to, but preferably 3 or more times the weight of the quantity of fresh lye or nigre introduced. <PICT:0837611/III/1> The principle is illustrated in Fig. 1 which shows a layer of molten soap S floating on lye L, the soap being introduced through 3 and lye through 1.  The soap and lye separate by gravity in countercurrent, soap being removed through 2 and lye enriched with glycerol through 4.  Some of the separated lye, however, is recycled through 5 by pump 6 and reintroduced to the soap layer by diffuser 7, which mixes it with fresh lye entering through 1. Fig. 5 illustrates an arrangement of four washing units A, B, C, D, each of which contains a funnel 28 (see unit A) which really belongs to the unit following the one in which, for convenience, it is disposed.  Thus, funnel 28 belongs to unit B.  Fresh lye enters funnel 41 by conduit 27, while crude curd soap passes by line 29 to funnel 28.  Lye in unit B is the richest in glycerol, so some is removed by means of pump 39 and line 30, while the rest is passed through mixer 37, which mixes it with the crude soap, and is thereby returned to unit B where it separates, the soap eventually spilling over into funnel 40 where it is later mixed with recycled lye from unit C.  In this way the soap finds its way in turn from units B, C, and D to A, in each unit being washed with lye which passes in turn from units D, C, and B to A, i.e. the soap and lye flow in countercurrent.  The quantity of lye recycled in each unit is controlled by interfacial floats such as 33, 36 which operate valves 32, 35.  Soap which finds its way eventually into the last unit A rises to the top on separating and overflows into gutter 42, whence it is removed (see also Fig. 6). Nigre, if used, is suitable only for the later stages of a multistage process, when the amount of glycerol has been reduced to the level normally present in nigre. Specifications 612,014 and 623,224 are referred to.

Title: A method for producing rolled steel products
IPC: C22C33/02
Filed: 1961-09-06
Abstract: <PICT:0996199/C6-C7/1> In a process of forming sintered rolled iron or steel products from porous iron powder, the powder is mixed with tar, pitch, dextrin or water as a binder, the mixture is spread on a support and hardened by, e.g. drying or heating or freezing, then compacted, rolled and sintered.  The iron powder may be iron sponge or oxidic iron powder containing carbon which may be added as pig iron, cementite or another metal carbide.  The sintering and heat treatments are carried out in a reducing and carburizing atmosphere so that the carbon content of the material may also be adjusted during the heat treatments.  Sintering is effected at 600-1200 DEG C. As shown in the Figure, the powder is fed on to moving belt 2 as a layer 4 and passed through a drying furnace 5.  The dried and hardened layer is removed from the belt rolled at 6 to a compact having a green density of 4 gms./c.c., sintered at 7, rolled at 8, annealed at 9 and rolled at 10. Further heat treatment, cold rolling, annealing and temper rolling is then carried out.  Specification 996,198 is referred to.
