Title: Method of separating higher boiling components from steam distillates
Inventor: DUMMETT GEORGE ANTHONY
IPC: C10C1/04
Filed: 1950-06-06
Abstract: Fractional condensation of a vapour mixture comprising steam and a higher boiling component, e.g. the vapour mixture from the steam distillation of tar acids, is effected by introducing the mixture at subatmospheric pressure into a surface condenser maintained at a temperature above the condensing temperature of steam but below that of the higher boiling component whereby the latter is condensed, passing <PICT:0703476/III/1> the residual steam to a second condenser, e.g. a spray type condenser, and effecting cooling of the first condenser at least partly by means of the condensate from the second condenser.  If a mixture of steam and tar acid vapours at an absolute pressure of 2" Hg. is introduced into a surface condenser supplied with cooling-water maintained at 40 DEG  C., the tar acid condensate contains only 1.3 per cent. water, while the vapours passing to the second condenser contain only 1.7 per cent. tar acid. If the temperature of the first condenser is increased, the water content of the tar acid is even less.  A vapour mixture, containing steam and a higher boiling component, is introduced through pipe 1 into surface condenser 2.  Cooling water is supplied to, and discharged from, condenser 2 through pipes 3 and 4, respectively. The condensate of the higher boiling component, formed in condenser 2, is separated from steam in separator 6, and is then withdrawn from the system through pipe 7.  The steam is passed from separator 6 into jet condenser 9, where it is condensed by contact with water from spray 10.  The flow of water delivered by the spray is regulated, by valve 13, controller 14 and temperature-responsive element 15, so that the temperature of the water discharged from the condenser through outlet 12, is only a few degrees below the boiling point at the pressure within the condenser.  This outlet water passes to a tank 16 where it is heated by steam, injected in automatically controlled amounts through pipe 17, so as to maintain the water at the temperature required for condenser 2.  The water is pumped from tank 16 to condenser 2 through pipe 3.  If the load on condenser 2 is greater than that on condenser 9, extra water is added through pipe 35.

Abstract: 541,833. Stapling. EVERY, C. E. (Bohm & Kruse Maschinenfabrik). May 11, 1939, No. 14129. [Class 89 (iii)] A stapled butt joint is produced by driving a staple across the joint, bending the projecting legs of the staple across the joint, and then driving them into the underside of the work. The staple 3 is driven slightly out of perpendicular to the joint of the boards 1, 2 and its projecting legs are bent through a right angle by inclined faces 10, 12 on blocks 6, 8 carried by sliding plates 4, 5. As the staple is further driven, the legs are bent through a further angle by faces 11, 13 on the blocks, which, at this time, are moving past each other. When the staple is fully driven, inclined faces on further blocks 7, 9 on the plates engage the legs and bend them across the joint, so that the previously bent ends are driven into the under side of the boards. The staple may have a single long leg which is bent as described. The plates 4, 5 are carried by carriers 22, 23 which are reciprocated in opposite directions in the table 21 of a stapling machine 18 by a rod 32 and linkage 28-30. The carriers 22, 23 and plates 4, 5 are adjustable for various sizes and spacings of staples.

Title: Improvements in or relating to the dying of suede leather
IPC: D06P3/32
Filed: 1955-05-17
Abstract: Chrome, chrome-synthetic or chromealum tanned suede leather is dyed in level, deep shades by impregnating the dry leather in a rotating drum with a cold concentrated solution of an acid- or directdyestuff in the presence of a wetting agent until fully penetrated, continuing the dyeing process with an increased liquor ratio and finally completing it at a higher temperature with a second addition of dyestuff, if desired applied from a fresh bath.  Inclusion of the wetting agent may be effected by treating the leather, during or after tanning, with an anionic, cationic or non-ionic fat-liquor which contains, or has an emulsifier containing, a hydrophilic group. Alternatively, the wetting agent may be added to the dyestuff or to the dyestuff solution.  When applicable, the dyeing may be diazotized and developed.  Numerous examples are given.  Specifications 502.767 and 526,015 [both in Group IV] are referred to.

Abstract: 1378946 Universal joints ANSCHUTZ & CO GmbH 27 March 1972 [29 March 1971] 14335/72 Heading F2U A dynamically-tuned (see end of this abridgement) universal connection, between a high speed rotor 12, e.g. of a gyro or measuring instrument, and its shaft 10, comprises an intermediate member 24 therebetween, articulated to the rotor 12 and shaft 10 respectively about transverse axes B, C mutually at right-angles, by pairs of blade springs 20, 22, which form, in effect, spring hinges of a Hooke's joint; and an additional flat blade spring spider 38 is arranged transversely directly connecting the rotor 12 and shaft 10 for centring. The arrangement is such that linear forces acting in any direction between the rotor and shaft subject the springs predominantly to tension. In Fig. 1 the blade spring pairs 20, 22 are arranged in radial planes B, C, ninety degrees apart, the diametrically opposite springs of the pair 20 being received at mid-length in slots in lugs 14 projecting inwardly from the rotor 12, whilst those of the pair 22 are similarly received in outwardly projecting arms 18 of the shaft hub, both ends of all the springs 20, 22 being received in slots at opposite ends of the intermediate member 24. The centring spider 38, which may have an outer as well as an inner ring is clamped internally and externally between the halves of the shaft hub and rotor respectively which are divided in the Hooke's plane BC and held together by screws, the spider arms 38 passing with clearance through windows in the intermediate member 24. To ensure that the centre of gravity of the rotor system lies in the Hooke's plane BC, so that it is neutral to accelerating forces, the axial position of the centre of gravity can be adjusted by a central axial screw 36 in the intermediate member 24. In Figs. 4 to 8, not shown, the Hooke's bladesprings 20, 22 and centring spring 38 of Fig. 1 are combined into a single spring having radial spokes such as 38, but terminating outwardly in segments which have ends folded through a right angle in each direction to form the Hooke's springs 20, 22. In Fig. 9, not shown, the hub (916) of the shaft (910) is hollow and is arranged radially between a cylindrical intermediate member (924) and the rotor (912). The connection is described as being dynamically tuned, when for a particular speed of operation, the oscillation of the intermediate member about its transverse axes generates inertia forces which counterbalance the restoring force of the connecting springs. The spring constants and mass of the intermediate member are correlated for this purpose.

A stamping press in association with an unloading device comprises two flexible or articulated suspension members of elongated form, e.g. sprocket chains or cables, spaced apart and parallel to each other and extending alongisde opposite lateral boundaries of the working zone and each supported by rotary or oscillatory supporting elements journalled for rotation or oscillation about transverse horizontal axes, transmission means operatively connecting one or more of these suspension members with the press ram or slide or with the driving means therefor so as to move said member or members in timed relationship with the ram or slide, and a conveyer platform spanning the suspension members formed so as to be capable of articulation or flexing, means being provided in association with the ram or slide for elevating the workpiece on the return stroke of the ram or slide above the platform before delivery of the workpiece on to the platform for transportation thereon out of the working zone of the press. The lower die 11 of the press is mounted on a table 10 and guides 14 accommodate the press ram 13 which carries the upper die 62. The ram is crank or eccentric-operated by a flywheel through a friction or key-clutch to provide single stroke operation. The unloader device is mounted on flanged girders 16 (Fig. 3), supported on the table 10. A framework 19 at one end of the girders supports a horizontal drive shaft 29 carrying sprocket wheels 30 and 49. At the other end of the girders an idler sprocket wheel 31 is mounted on a shaft 32. A sprocket chain 33 connects the driving and idle sprockets 30 and 31 respectively. Carried on the chain is a conveyer platform 40 comprising a plurality of metal, wood or plastic channel-shaped slats 41 extending the width of the working station. The platform may be slightly inclined to the horizontal plane so that a workpiece does not tend to slide off when delivered on to the platform. :The drive shafts 29 are driven from chain and sprocket gearing mounted on shafts 52 and 45, the chains 57 being attached to the press ram by adjustable links 58 (Fig. 2). The transmission gearing effects a 4.1 step up between ram and conveyer platform displacement. In operation, the conveyer platform 40 is removed from the working zone during the first portion of the down stroke of the ram and during the final stages of the return stroke the platform is moved into the working zone to receive the formed workpiece 61 when freed from the upper press tool or die 62 by the ejectors 63. In a modification, both the insertion and withdrawal of the conveyer platform is effected during the upward or return stroke of the ram in order to allow for completely unobstructed headroom between the upper and lower tools for the insertion of a new workpiece.
