Title: "purification of amyloglucosidase and preparation of dextrose"
IPC: C12N9/34
Filed: 1958-03-03
Abstract: Amyloglucosidase (alpha-glucosidase, glucamylase-starch glucogenase) is purified by treating an aqueous solution or suspension thereof with 2 to 5% of a water-insoluble hydrous synthetic magnesium silicate at a pH of 3,8 to 4,5, separating the solids and recovering the amyloglucosidase as the liquid phase.  The crude amyloglocosidase may be in the form of the whole or clarified broth of an amylase-producing microorganism such as Aspergillus niger, a suspension of a dried or partially dried amyloglucosidase preparation or a solution of a completely soluble enzyme preparation.  In the case of suspensions, it is preferred to remove solids before adding the adsorbent.  The enzyme liquid and adsorbent are preferably mixed at 5 DEG  to 30 DEG  C. for 30 to 60 minutes.  The liquid is separated from the solids and is used in the preparation of dextrose from starch (see Group VI).ALSO:A process of producing dextrose from starch wherein the starch in aqueous system is hydrolysed with an amyloglucosidase, the hydrolysate clarified, concentrated, and the crystallised dextrose separated from the mother liquor, characterised in that the amyloglucosidase solution has been purified by removing impurities by adsorption on a water-insoluble hydrous synthetic magnesium silicate (see Group IV(b)), the final hydrolysate having a maximal true dextrose content of 93 to 94%, dry basis.  It is preferred to use a pure starch which has been subjected to a preliminary acid hydrolysis so that a workable fluid is obtained at a solids concentration of 25 to 50%, and especially 35%, at 45 to 60 DEG C.  A pH of 4 to 5 and temperature of 35 to 45 DEG C. are preferred.

Title: Improvements in or relating to latching and locking mechanism, e.g. for the landing gear of aircraft
IPC: B64C25/20
Filed: 1939-03-01
Abstract: 526,947. Locking aircraft undercarriages. WESTLAND AIRCRAFT, Ltd., and COX, R. P. March 1, 1939, No. 6720. [Class 4] [Also in Group XXV] A latching and locking mechanism for a pivoted member, such as the wheel carrying arm of an aircraft landing-gear comprises means for limiting the angle through which pivotal movement can be effected, splines or their equivalent on a fixed member and the pivoted member which are encircled by or encircle an axially movable latching member, and safety-locking means serving to prevent movement of the latching member when the pivoted member is in either of its extreme positions. As shown, a member 10 forming the wheel-carrying arm of an aircraft undercarriage has a pivot member 5 rotating in a member 1, a projection 8 on a ring 7, keyed to the member 5, co-operating with a stop to limit the angular movement of the member 10. Splines 12 are formed on the member 5 adjacent to a collar 11 and similar splines 13 are formed on a member 20 keyed to the member 1. An internally splined sleeve 14 of the same axial length as the splines 12 can be moved to engage or disengage the splines 13 by a spanner member 16 mounted upon the sleeve 14 by a ball bearing 15. A projection 18 on the member 16 is adapted to enter notches 18a on the member 20 and three projections 19 are adapted to engage notches 19a in the collar 11. The width of the member 16 and projection 18 is equal to the axial distance between the member 20 and the collar 11. Fig. 3 shows the arm locked in one position. Upon moving the member 16 by a jack acting upon an arm 17 the projection 18 moves within the notch 18a, which is wider than the projection, until the inclined faces of the notch and projection cause the member 16 to move axially to engage the projections 19 with the notches 19a and disengage the sleeve 14 from the splines 13. Continued movement then rotates the arm 10 until stopped by the projection 8, whereupon continued rotation of the member 16 causes axial movement of the member 16 to bring the projection 18 into another notch 18a and the projections 19 into engagement with the surface of the collar 11. The splines may be replaced by polygonal surfaces or by keyways and the latching sleeve may be internal instead of external. The projections 18, 19 and their co-operating notches may be reversed and antifriction rollers may be provided on their surfaces. A rib and groove may replace the ball bearing 15, or these may be radial pins on the sleeve 14 engaging circumferential slots in the member 16, or the positions of these may be reversed. Rollers may be provided in the pins. The locking means may be applied to the retractable undercarriage arm described in Specification 526,946.

Abstract: 1,041,571. Securing insoles to lasts. BAIN INTERNATIONAL Inc. Feb. 20, 1963 [Feb. 21, 1962], No. 6776/63. Heading A3B. An insole 30 (Fig. 1, not shown) is positioned on a last 26 by applying force to the periphery of the insole at three selected points at least to move the insole into coincidence with the last, and combined with the last while the force is maintained. The last is supported on toe and heel rests 32, 34 which are individually adjustable heightwise and lengthwise of the last, a toe guide finger 62 facilitating initial loading, and the insole, previously taped with a double-faced pressure sensitive tape, is placed on the last. When the machine is set in operation back guide assemblies 42, 44 move from a remote position to an aligning position, and flat, spring- pressed swivel plates 74, 76, adjustably mounted on arms 78, 80, bear against the heel portion of the last, in longitudinal relation thereto, deflecting any overlapping portions of the insole. Front guide assemblies 48, 50, with similar plates 96, 98 then engage the toe portion of the last in similar manner, and plates 74, 76, 96, 98 co-operate to align the insole correctly. The guide assemblies may move longitudinally parallel to the centre line of the last instead of transversely as shown. RRoller 118 then drops to engage the toe portion of the insole, is pressed thereagainst by springs 120, and moved lengthwise of the shoe to join the insole to the last by means of the tape. The roller is then raised and returned. Heightwise movement of roller 118 is controlled by cam 116, and reciprocating movement by means of pin 70 on crank disc 72 engaging in slot 148 of connecting rod 150. Movement of guide assemblies 42, 44, 48, 50 is controlled by cams 156, 158, 176 and 178 respectively. In the alternative guide arrangement shown in Figs. 10-13, vertical roller guides 200, 201 at the toe, and 202, 203 at the back are each supported on a double swivel yoke arm adjustable transversely of the last on a bar 208 which is adjustable vertically on a guide arm 216. The rollers are moved longitudinally into engagement with the last. Guide plate 222, shown in Fig. 14, has a ball and socket mounting, and is adjustable laterally of the last. Toe guide plates 96, 98, and rollers 200, 201 may have a resilient layer, e.g. cellular foam rubber, so that they may position an insole which is shorter than the last (see Fig. 15).

Title: Improvements in or relating to television or like systems and apparatus
IPC: H04N5/04
Filed: 1925-10-21
Abstract: 269,834. Baird, J. L. Oct. 21, 1925. Television; synchronous movements. - Synchronism is maintained in a television system by the use at the receiving station of an image transmitted or controlled from the transmitting apparatus, such image being separate and of markedly different intensity from the picture being transmitted. In one receiving arrangement, Fig. 1, there is produced along one edge of the reproduced picture 11 a highly illuminated band 12 corresponding to a luminous object such as a lamp filament at the transmitting station, and during synchronous running the band 12 is disposed between light-sensitive cells 13, 14. Any divergence from synchronism produces movement of the band to activate one cell or the other according to the direction of the divergence, and the resulting current is employed to act upon an amplifying and controlling device 15 or 16 to accelerate or retard the receiving apparatus 17. In another arrangement, Fig. 2, a lamp 20, flashed intermittently under the con. trol of a periodic synchronizing impulse from the transmitting apparatus, co-operates with radial slots in a disc 22 driven from the receiving apparatus to produce on a screen 24 a band of illumination 25 coacting with two light-sensitive cells 26, 27. Alternatively the disc 22 may be replaced by a rotating mirror. The distance between the cells 13 and 14 or 26 and 27 may be adjusted. The two cells may be replaced by a single cell positioned so that half of its area from one edge is illuminated during synchronous running.

Title: Improvements in or relating to magnesium base alloys
Inventor: BALL CHARLES JAMES PRIOR
IPC: C22C1/02
Filed: 1945-03-22
Abstract: A process for the production of magnesium base alloys containing zirconium wherein a zirconium containing substance is reacted with molten magnesium in the absence of any appreciable quantity of zirconium alloying inhibitor elements, said substance comprising zirconium fluoride mixed or combined with one or more of the fluorides of lithium, barium, strontium, calcium and magnesium, which are so selected that the fluoride or fluorides both with and without the magnesium fluoride produced during alloying will be sufficiently fluid to facilitate easy mixing of the salts with the magnesium in order to permit the alloying of the zirconium with the magnesium at the temperature employed which may be for example below 850 DEG C, the mixture containing at least 5 per cent of zirconium.  Zirconium fluoride is defined as a material containing at least 20 per cent of fluorine, at least 90 per cent of fluorine, oxygen and zirconium together and is substantially free from hydroxyl groups.  Zirconium alloying inhibitor elements are those which form high melting point compounds with zirconium insoluble in magnesium.  The substance preferably consists solely of the specified fluorides, but it may p contain also one or more chlorides or bromides of potassium, sodium, lithium, barium, strontium calcium and magnesium and reducible halides of elements which do not inhibit alloying of zirconium.  The substance may contain not more than 2 per cent of lithium, if any, and fluorides of at least three metals other than zirconium and lithium.  The substance may be used in the form of prefused lumps. Alloying may be carried out by pouring molten magnesium on to the substance which is in the form of prefused lumps or a fused bath. Specifications 511,137, 511,482, 533,264, 539,023, 549,024, 652,223 and 26438/39 (as open to inspection under Sect 91), are referred to.
