Title: Process for the recovery and purification of vitamin b concentrates
IPC: C07H23/00
Filed: 1956-03-19
Abstract: A digested sludge or other fermentation products produced by anaerobic fermentation is enriched in vitamins of the B12 group in a process in which the coarse components of the sludge having little or no B12 activity are removed at a temperature below 30 DEG  C., for example by means of a centrifuge or vibrating screen, whereby a "thin sludge" containing the vitamins of the B12 group combined with the suspended fine sludge particles is obtained which is subjected to further treatment.  The thin sludge may be treated as follows: (A) it is heated in the presence of 0.05-0.2 per cent SO2 at a pH value 6-7, thus liberating the Vitamin B12, the solid components removed by centrifuging or filtering and the filtrate concentrated by adsorption and elution techniques; (B) it is thickened at temperatures below 30 DEG  C., by filtration, centrifuging, by vibrating clarifying means or by simple settlement, to obtain a thick sludge of about 1/3 to 1/4 the volume of the original sludge.  This thick sludge may be further treated as in (A) above; (C) it is separated off at temperatures below 30 DEG  C. by filtration, centrifuging, or by vibrating clarifying means and a succeeding sludge press and the resultant sludge agitated with water, and further treated as above.  Examples illustrate the preparation of Vitamin B12 adsorbed on active charcoal by the methods described above.ALSO:As a feed supplement with APF activity, there may be employed an eluate having a vitamin B12 activity which corresponds to 3-4 mg. per g. dry substance, incorporated in a suitable carrier substance such as food yeast or soya bean meal; such an eluate is obtained in a process of enriching vitamins of the B12 group in digested sludge or other fermentation products produced by anaerobic fermentation, in which the coarse components of the sludge having little or no vitamin B12 activity are removed at a temperature below 30 DEG C., for example by means of a centrifuge or vibrating screen, whereby a thin sludge containing the vitamins of the B12 group combined with the suspended fine sludge particles is obtained which is subjected to further treatment (see Group IV(b)).

Title: Improvements in winding devices for clocks, watches and other clockwork movements
IPC: G04B5/08
Filed: 1928-03-22
Abstract: 310,160. Stringer, H. L. March 22, 1928. Winding - apparatus for clockwork includes a weight which is oscillated by vibrations to which the clockwork is subjected and which drives the winding arbor through cord and pulley mechanism constituting a unidirectional drive. The winding arbor b of the going-barrel is geared to the driving spindle e in the reduction ratio of 64 :1 by wheels d, f and intermediate spindle c. The driving weight g is held between two parallel plates h, pivoted at k to the fixed casing and supporting four pins n<1> - - n'. The weight is supported by springs m attached to pins m<1> on the plates h and to the top of the casing. A cord p<1> fixed to pin n<3> passes clockwise, Fig. 1, round pulley o<1> fixed on spindle e and is connected through spring q<1> to pin n<1>. A second cord p<2> passes from pin n<2> clockwise round a second pulley o<2> fixed to spindle e and to spring q<2> and pin n<4>. The arrangement is such that as the weight sinks cord p<1> rotates spindle e anti-clockwise and cord p<2> is ineffective; on the up-stroke of the weight the cord p<2> becomes effective and drives spindle e, also anticlockwise. This gives a unidirectional drive for the arbor b. In a modification, the gearing c - - f is replaced by a worm and worm-wheel, the shaft e being in a plane parallel to the plates h. A handwinding key may be added. A single cord p<1> or p<2> may be used as in Specification 193,997, and the springs q<1>, q<2> may be blade springs. Over-winding, preventing. With the construction shown in Figs. 1 and 2, the spindles c and e are mounted between triangular plates r pivoting about the spindle b, Fig. 3. Thus when the spindle e drives, there is a tendency for pinion d to roll clockwise round the spur-wheel d. This is resisted by a spring s until the mainspring is fully wound and its resistance causes spring s to stretch. The plate r then pulls a rod t to the left so that its large end just fits a hole in the weight g and prevents the latter oscillating. Alternatively, to prevent overwinding a lever may be moved by the expanding mainspring to lock the weight against vibration or to disengage a clutch between the weight and the arbor b.

Filed: 1939-03-20
Abstract: 526,552. Oil seals. CHICAGO RAWHIDE MANUFACTURING CO. March 20, 1939, No. 8816. Convention date, March 23, 1938. [Class 122 (v)] An oil seal of the type comprising a sleeve packing 13 held in a casing 10 is made by contracting or expanding one edge of an apertured disc to form a sleeve and inserting said edge in a channel or between clamping elements in the casing. A washer 18 may be pressed axially between a conical casing 16, Fig. 6, and a central member 15 having a greater diameter than the bore of the washer, by a movable member 19 which turns the outer periphery of the washer downwardly and engages it in the channel of the casing 10. In an alternative method, Fig. 16, after engagement of the packing and casing, continued pressure on the movable member 33 moves the central member downwardly and causes dies 32 to move outwardly on a conical member 37 to deform the wall of the channel into engagement with the packing. In a further method, Fig. 2], the sleeve 46 is deformed on a mandrel and clamped between the casing 47 and a ring 49 carried magnetically by the movable die 50 during the deforming operation. External seals may be made in the same way, the small diameter end of the packing sleeve being inserted in the casing in this case. The sleeve packing 11', Fig. 1 is pressed by spring 12 on a radial shoulder on a shaft.

Title: Improvements in or relating to eyeletting machines
IPC: A43D100/02
Filed: 1938-03-24
Abstract: 512,868. Eyeletting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and HOPE, E. March 24, 1938, No. 8988. [Class 43] In an eyeletting or like machine having a pair of setting dies and a pivoted raceway, a link is arranged to be moved as a result of relative movement of approach between the dies to operate a pivotally mounted member which swings the raceway about its pivot so that it does not hinder setting movement of the dies. As shown, the machine has a fixed setting die 1, and a hollow upper setting die 7 mounted in a plunger 5 movable vertically in bearings in an arm 3. Movable vertically in a bore 11 in the die is an eyelet entering spindle 9, the head 13 of which is split vertically to wedge on the bore. Upward movement of the spindle 9 occurs when it meets the lower die 1 and the eyelet is firmly clenched between the dies ; the spindle is pushed outwards on the return motion of the plunger 5 when its head 13 comes into contact with an ear 53 formed on a pin 55 extending through a vertical slot in the plunger across the bore 11. The plunger is connected by a crank 15 and a link 17 to the forward end of a forwardly and rearwardly extending power driven shaft 19 housed in bearings in the plunger so that rotation causes rising and falling movements of the plunger. The eyelets are fed from a hopper 27 into a raceway 25 pivoted at 23 on a block 21 extending from the arm 3. At its lower end, the raceway is provided with a spring-pressed retaining latch 33 similar to the one referred to as 58 in Specification 176,519, [Class 43]. The raceway is moved about its pivot by a spring 28 to an extent determined by the engagement of a stop surface 29 with an adjustable stop 31. The rearward movement of the raceway is effected by a pivoted link 39 which is pivoted at its mid point to a second link 41 pivoted to a collar 43 adjustably fixed to the plunger 5. The lower end of the raceway can be prevented from entering between the dies whilst being oscillated and the machine run idly by pushing a pin 49 normally kept in the block 21, through a hole 47 in the link 39 so that its projecting ends contact with the outer edges of the side walls 51 of the raceway.
