Title: A process for the production of nucleoside-5 diphosphates
IPC: C07H1/02
Filed: 1962-05-25
Abstract: Nucleoside-51-diphosphates are prepared by keeping cell bodies or destroyed cell bodies of a microorganism belonging to the class Schizomycetes (bacteria) in an aqueous salt-containing medium of pH6-10 for 1 to 5 hours at 30-45 DEG C. in the presence of a phosphoric acid anion donor.  Specified donors are primary, secondary and tertiary phosphates of sodium, potassium or ammonium. The concentration of phosphate anion may be 0.01 to 0.05 mole per litre and the total salt concentration 0.1 to 10 mole per litre. The cell bodies may be destroyed by crushing, sonic or supersonic waves, chemical agents (e.g. phenol, toluene, ethyl acetate or formaldehyde) or by lysozyme, e.g. in egg white, The pH may be maintained by means of buffers or by addition of acid or alkali as required.  Phosphatase inhibitors may or may not be added.  The products may be isolated by conventional methods, e.g. charcoal or ion-exchange chromatography processes, or as their organic or inorganic salts.  They may be used as condiments (see Division A2).ALSO:Nucleoside - 51 - diphosphates prepared from cells of Schizomycetes are used for food flavouring, alone or mixed with a carrier.  Other seasonings such as 51-nucleotides, salts of amino acids (e.g. monosodium glutamate), sodium chloride, succinic acid, vinegar, or spirits may be present.

Title: Improvements in loading devices for automatic firearms
IPC: F41A9/51
Filed: 1952-08-15
Abstract: 731,442. Automatic firearms. VERWALTUNGSGES. DER WERKZEUGMASCHINENFABRIK OERLIKON. Aug. 15, 1952 [Dec. 21, 1951], No. 20561/52. Class 92(2). The actuating device, such as the gas piston 6, of an automatic firearm is driven rearwards either by gases issuing at 31 from the gun barrel 3 or by gases generated in a chamber 18 by an auxiliary cartridge 14, there being two connections one from each source of gas to the actuating device and there being means to prevent the shell-propelling gases going over into the chamber 18. The firearm is of the kind having a rotary drum fitted with a number of cartridge chambers. In Fig. 2 the gas piston 6 in a cylinder 7 is normally actuated by gases from the gun barrel 3 and serves to rotate a cylinder fitted with a number of cartridge chambers and to feed a new cartridge into one of the empty chambers. In front of the cylinder 7 and rotatably mounted on a stub shaft 12 projecting from the gun casing 1 is an annular casing 13 provided with a number of bores 13a for receiving cartridges 14. These cartridges can be brought successively into line witha bore 18 in the casing 1 and when fired, by electric means, drive to the rear a piston 20 whose rear end bears against a projection 21 on the piston 6. Piston 6 is thus driven to the rear to effect the cocking of the firearm and is subsequently returned by a spring, the pressure gases in the meantime having been exhausted through a port 22. The conductor 27 of the firing circuit is located in a cap 23 which fits, by a bayonet joint 25, on the shaft 12 and is secured against rotation by a lever 26. The casing 13 may be rotated, as in the case of the modification shown in Figs. 3 and 4, by the reciprocation of a slide 37 carrying a pawl 39 adapted to engage teeth 30 on the casing, a further pawl 41 serving to prevent rotation in the opposite direction. In this modification the gases produced by a cartridge 14 drive to the rear a spring-controlled slide 34 thus (a) breaking a connection 31, 34a, 31a, between the barrel 3 and gas cylinder 7, and (b) establishing a connection 34b, 31a, between the cartridge and cylinder 7. In another modification the charge carrier 13 is flat and slidable. Specifications 689,155 and 697,934 are referred to.

Abstract: 327,648. Kent, G. P. July 5, 1929. Non - endless chain and like carriers, apparatus with; illumination, changing advertisements by controlling; moving apparatus combined with clocks. -A sign in which a display strip is intermittently unrolled from one drum and wound on to another comprises means whereby the strip is engaged by claws which drag it into position and means whereby the direction of motion of the strip is reversed after each unwinding. The pictures forming the strip are bounded bv transverse rods 30 the ends of which lie in side channels at the display position, and are engaged by vertically reciprocating claws 31. The claws are mounted on slides 33 which are moved up and down by the engagement of a pin 70 on an endless constantly moving chain 51 with an extension 71 of the slides, the slides being counterbalanced by a weight 100. After the claws 31 have drawn the strip along they are disengaged therefrom on their return by a lateral movement of the claws 31, slides 33, and their guides 34, the guides for this purpose being suspended from parallel links 38, 39. The means for swinging the guides 34 consists of a cam 46 having projections 63, 64 which are engaged in turn by two pins 61, 62 projecting from the chain 51. The cam 46 controls the guides 34 through a pivoted lever 44 and a link 42, the lever being held against the cam by a spring 45s. Claws 31b on the guides 34 engage the rods 30 to restrain the strip from slipping back when the claws 31 are disengaged. The reversal of the strip is effected by a projection 80 on the last picture engaging an arm 82 on an endless chain 83 and so rotating a crank pin 88 which forces a rod 90 against a pin 92 projecting from the cant 46. This rotates the cam to bring the projections 63, 64 out of the path of the pins 61, 62, and allows the claws 30 to take back this end picture and to change the sense of their ineffective stroke. A lamp 110 is lit after each picture has been brought into position by a switch controlled bv the swinging guides 34. The storage drums 2, 3 are geared together by a chain 4, and the strip is maintained taut through the varying diameters of the drums by suspending a weight 8 in a bight of the chain, a lesser weight 13 in another bight being provided to give tension to the chain. The apparatus is contained in a clock case and the pictures are viewed through a transparent mirror.

Abstract: 782,717. Gear-cutting; gear-finishing. PRAEG, W. S. July 19, 1955 [Aug. 23, 1954], No. 20848/55. Class 83 (3). In a method and machine for roughing and finishing gears in a single operation the tool comprises several cutting sections 18a-18e increasing in diameter from a plain guiding portion 14. It is rotated in timed relation with the work 10 and advanced through the work until the portion 18e reaches the point X. The work is then moved axially in the opposite direction so that all teeth are cut to depth by the portion 18e. Both work and tool may have geared compensatory movement to take account of helical teeth, or may be guided by splines of the same angle as the teeth so that the rate of feed may be varied regardless of the helical angles. The axes are crossed at from 5 to 45 degrees. The cutter may have several sets of finishing teeth which are brought into operation in turn when the preceding set becomes blunt. Alternatively, the finishing teeth may be combined with shaving teeth so that the tooth is cut and shaved. In one machine, the cutter 70 is advanced by a manually-rotated screw 76, Fig. 4, and is rotated by a gear 56 on a straight-splined shaft 54. The work 86 is traversed by a screw 90, the drive-gear 84 being on a helicallysplined shaft. In a modified machine, the work W, Fig. 5, is clamped by a pneumaticallyoperated centre 122 and is traversed by a piston 108, and the movement compensated by splines 118. The cutter C on a slide 138 is advanced by a fluid-pressure device 140 and the movement compensated by splines 142. The slide 138 is carried by a member 130 adjustable angularly about a shaft 132 on a horizontallyadjustable slide 126. Switches 184, 188 and dogs 186, 190 provide for an automatic cycle.
