Title: Method for producing inosinic acid and adenylic acids by fermentation
IPC: C12P19/32
Filed: 1962-03-06
Abstract: A method for producing 51-inosinic acid, 31-adenyli acid or 51-adenylic acid comprises aerobically culturing a micro-organism which requires at least one growth factor selected from quanine, xanthine, hypoxanthine and thymine in a medium containing a source of assimilable carbon, a source of assimilable nitrogen, inorganic salts and from 2 to 90 m g/ml. of each required growth factor.  The growth factors may be added as yeast extract.  The products may be isolated by ion-exchange (details given), adsorption, precipitation or extraction processes and may be isolated as salts, e.g. of barium or sodium.  Other growth factors may be required, e.g. isoleucine, glycine, aspartic acid, glutamine, fumaric acid, formic acid, p-aminobenzoic acid, biotin and folic acid. Suitable strains of micro-organism may be obtained by standard methods of inducing mutation, e.g. from Micrococcus glutamicus, Bacillus subtilis, Escherichia coli, Brevibacterium ammoniagenes, Candida utilis, Penicillium chrysogenum, Aspergillus niger, Streptomyces grieus and Neurospora crassa.  Glutamic acid may be formed as by-product when using a Micrococcus glutamicus strain.

Title: Improvements in or relating to spring arrangements for motor vehicles and trailers therefor
IPC: B60G11/04
Filed: 1954-03-26
Abstract: 746,322. Spring suspensions. SCHNATMEIER, F. G., SCHNATMEIER, H., and SCHNATMEIER, R., [trading as SCHOMACKER & CO., H.]. March 26, 1954 [Dec. 28, 1953], No. 8905/54. Class 108 (2). A spring arrangement for a motor vehicle or trailer comprises a substantially semi-elliptic main spring assembly 1 pivotally attached at one end to the vehicle frame and a shorter laminated auxiliary spring 3 secured at least near one of its ends to the frame and extending therefrom in substantially the same direction as the main spring assembly, the main spring assembly and the auxiliary spring freely and slidably contacting each other at least near their free ends in the unloaded condition of the arrangement, thereby to flatten when loaded and causing the region of contact between the two spring asemblies to shift towards the secured end of the auxiliary spring when the load upon the arrangement is being increased. According to Fig. 2, the auxiliary spring 3 bears against a stop 4 and at full load on the vehicle, the spring 1 contacts the spring 3 on the region of the stop. In another arrangement, Fig. 3, the spring 1 bears against an abutment 5, which may be mounted on an adjustable eccentric, Fig. 4 (not shown). The stop 4 may additionally or alternatively be adjustable. The auxiliary spring 3 may comprise two or more laminated leaf spring bundles or it may be unilaterally clamped and/or the abutment 5 may comprise a resilient member, the auxiliary spring being biased by displacing a clamping block therefor.

Title: Manufacture of film of improved uniformity of thickness
IPC: B29C48/08
Filed: 1964-03-03
Abstract: 995,718. Film making apparatus. AVISUN CORPORATION. March 3, 1964 [May 27, 1963], No. 8986/64. Heading B5B. In apparatus for making a continuous film by extruding a continuous, generally flat stream of film-forming material into a bath to set the stream into a film advancing the film through the bath and then withdrawing it from the bath, means are provided within the tank, and along the path of the extruded stream, for engaging the film after it has set and causing selected longitudinal portions thereof which are thicker than the remainder of the film to travel at a greater speed than the remainder of the film, whereby the thicker longitudinal portions of the film are longitudinally stretched to a greater extent than the remainder of the film and thereby reduced in thickness to a greater extent than the remainder of the film, whereby thickness variations across the width of the film are reduced. As shown in Fig. 1, a continuous flat stream 13 of film-forming material, such as molten polyethylene or polypropylene is extruded from the nozzle 11 into a quenching or coagulating bath 15 which sets the stream 13 into a web of film which is engaged by the tension frame or wiper bar assembly 27 and thereafter passes over the guide rollers 21 and 23 and out of the bath at 19. The assembly 27 is pivotally supported below the surface of the bath 15 by brackets 29 mounted on the inner surface of the bath tank 17 (Fig. 2). The frame 27 includes at least one, and preferably a pair of guide bars or rolls 31 supported between trunnions 33. At the start of the process the stream 13 is extruded downwards between the rolls 31 and the frame 27 is then rotated to the position shown in Fig. 1 and locked in this operative position. The rolls 31 each include a long central sleeve 37 (Fig. 3), a series of short or spacer sleeves 39, tapered end sleeves 41, and a supporting shaft 43 on to which all the sleeves are locked. Since the end sleeves 41 taper towards the spacer sleeves 39, the end sleeves 41 cause the edge portions of the film 19 which are engaged with the sleeves to travel more rapidly than the remainder of the film and thereby to become stretched to a greater degree and thinner. The thickness of the edge portions of the film is thus reduced to that of the remainder of the film before the film becomes quenched or set. The guide bars 31 are preferably in the form of rolls which may be rotated relatively to the trunnions 33 by the movement of the film itself or by driven belts engaging pulleys 49. If the stream of film-forming material is thicker at its central region than at its edge region, the guide bar or roll 31 may have a sleeve which is thicker at its centre and tapers in both directions towards its ends.

Title: Improvements relating to linear-dimention gauges
IPC: G01B5/08
Filed: 1941-06-10
Abstract: 546,900. Linear-dimension gauges. BOLTON, E. June 10, 1941, No. 9060/42. Divided out of 546,843. [Class 106 (ii)] Relates to internal gauges incorporating a dial indicator and having a contractible part through movement of which the indicator is operated, this part carrying at least one radially extending projection for engaging the work, and consists in forming the radial projection as a screw which passes through a slit in the contractible part the slit being closed on to the screw by another screw to grip the latter in adjusted position. The invention is applied to the gauge set out in Specification 546,843 the work-contracting parts of which are formed by the end of a tube split longitudinally. Each of these contacts is provided with a radial slit 36 through which the radial contact screws 35 are passed and after adjustment are clamped by the screw 37. The gauge is centred in the hole by a spring pressed sliding collar with tapered webs to engage the end of the hole. When dismantled the gauge tube is closed by a plug the shank of which may act as a box spanner for adjusting the screws 35. Specification 495,506 also is referred to.

In a direct-current amplifier of the "chopper" type, in which a vibratory switch 7 alternately connects the input of an A.C. amplifier 10 to an input contact 5 and earthed contact 6, and a second synchronized switch 12 connects the amplifier output either to output contact 14 or to earthed contact 13, the condenser 16 across which the output is obtained is connected to contact 14 via a non-linear resistor 15 of the siliconcarbide type. The arrangement is such as to reduce the ripple in the output, since the resistance of resistor 15 is very high when contact 14 is isolated, so that the leakage current from condenser 16 over the switch contacts is minimized The voltage across condenser 16 is amplified in a D.C. amplifier 17; negative feedback is applied overall by connecting a potentiometer network 3, 4 between the input and output terminals 1, 2 respectively, the input contact 5 of the switch 7 being connected to the tapping point.

Abstract: Insecticides which may be used as substitutes for nicotine are provided by heating a liquid glyceride of a fatty acid with sulphur, adding sulphonated castor oil to the resulting sulphurised glyceride, saponifying the mixture and adding a small proportion of nitrobenzene thereto.  The glyceride may be castor or grape-seed oil and the glyceride may be heated with the sulphur until a sample remains clear on cooling.  The proportion of sulphur may be of the order of 5 grains per 100 cc. of glyceride and the proportion of sulphonated castor oil may be of the order of 20 per cent. of the sulphurised glyceride.
