Patent GB-986553-A (GB)
Title: Tobacco products
IPC: A24D3/06
Filed: 1962-10-01
Abstract: Flavourants are incorporated into tobacco products in a range of 0.05 to 5% by weight in the form of Diels-Alder adducts or their salts, the flavourants preferably being the diene and/or dienophile used to synthesize the adducts and being released only on smoking the tobacco.  The dienes which can be employed include (1) acyclic conjugates, e.g. butadiene, alkyl-butadienes, anylbutadienes and conjugated polyenes, (2) alicyclic conjugates including wholly alicyclic systems, bicyclic systems and alicyclic acyclic systems, (3) aromatic conjugates including wholly aromatic systems, aromatic acyclic systems, and aromatic-alicyclic systems, (4) heterocyclic compounds.  Compounds which can be employed as dienophiles contain a C=O bond (or one with an equivalent effect) conjugated with a C=C bond.  Such compounds are exemplified by (1) CH2=CHA, (2) C6H5CH=CHA, (3) CH2=CA2, (4) ACH=CHA, (5) AC=CA where A represents many specified groups, (6) Quinones.  Salts of the above adducts may be employed as flavourants, such as sodium (preferably), potassium, calcium, barium, lithium, aluminium, magnesium or other non-toxic salts.  Several examples are given of the preparation of the Diels-Alder adduct to be incorporated in the tobacco and many examples of the diene compounds and dienophile compounds are also given.  The prepared compound may be sprayed on to the tobacco.
Patent GB-898334-A (GB)
Title: Production of 5-nucleotides
IPC: A23L27/23
Filed: 1958-08-22
Abstract: 51-Nucleotides are obtained by degrading ribonucleic acid by treating it with cultured materials (as defined below) of microorganisms containing 51-phosphodiesterase.  The terms cultured materials is defined as living cells, dry cells, culture filtrates and cell extracts obtained in the culture of the microorganism.  The living cells may be prepared by growing a microorganism in a culture medium and after an appropriate culture period the culture medium is removed by centrifugation or filtration and the resulting precipitate is used as "living cells".  Alternatively, the living cells may be used without separation of the culture medium.  Dry cells may be obtained by washing the living cells (separated from the culture medium) with water and an organic solvent such as ethanol, methanol, or acetone and drying in a desiccator, although in some cases the washing process may be omitted.  Cell extracts may be obtained by grinding living cells or dry cells and then suspending them in water or an appropriate buffer solution.  After stirring the ground cells are removed by centrifugation and the resulting supernatant solution used as cell extracts.  The cultured material may be obtained from the cultivation of one or more species of the following genera: Bacillus, Streptomyces, Torula, Zygosaccharomyces, Penicillium, and Aspergillus.  Examples of these genera are Bacillus subtilis, Bacillus megatherium, Streptomyces aureus, Torula utilis, Zygosaccharomyces Z-12, Aspergillus oryzae, Penicillium citrinum, Penicillium purpurogenum and Penicillium multicolor.  The preferred microorganisms are Penicillium citrinum Thom 1131 and its pigmentless mutant.  The microorganism may be grown on solid or liquid media and as components of the culture medium the conventional carbon and nitrogen sources and inorganic salts may be employed.  Both the growing of the microorganism and the enzymic degradation of ribonucleic acid may be carried out simultaneously using culture medium containing ribonucleic acid or the process may be carried out in two stages in which case the growing of the microorganism and the enzymic degradation of ribonucleic acid are carried out separately. Crude solutions containing ribonucleic acid, e.g. yeast extracts may be used as starting materials.  Also, microbial cells which are obtained by cultivation may be used as a source of ribonucleic acid, the culture filtrates obtained simultaneously being employed as enzyme solution.  Examples are given for the production of mononucleotides from yeast ribonucleic acid solution using a cultured material derived from Penicillium citrinum Thom 1131 by surface culture or shake culture.  The mononucleotides present are identified as cytidine, adenosine, inosine, uridine-, and guanosine-51-monophosphates.  The inosine-51-monophosphate is obtained as a secondary product and xanthosine-51-monophosphate may also be formed as a secondary product.  Specification 898,335 is referred to.

Title: Nested container counting and separating mechanism
IPC: G06M3/02

Abstract: 1,246,062. Endless conveyers. KOEHRING CO. 23 July, 1969 [24 July, 1968], No. 37121/69. Headings B8A. [Also in Divisions G4-G6] An elongated nested stack of containers is assembled and a batching device enabled to count off a predetermined number and separate them from the rest. Cups C in vertical position are transferred from one conveyer 23 to another 17 and turned to horizontal by an air jet 31 before being blown along a tube 28 by another jet 32. A stack accumulates against a wedge 62 secured to a gear 58, Fig. 3, held in left-most position a until the stack builds up to cut off a photo-electric beam 34 for a significant time. A solenoid 51 then energizes to pull the gear 58 to the right, so as to engage with the rims of the cups. The conveyer 17 moves the stack to the left, Fig. 1, turning the gear 58 until it has completed one revolution, say 100 cups, when arm 67 closes a switch to cause pneumatic cylinder 47 to drive carriage 43 carrying gear 58 to the left. Solenoid 51 releases so that gear 58 returns to position a with wedge 62 acting as a stop and jets 63 are activated to assist separation of the batch. The carriage 43 and cylinder 47 return under spring action.

Progressive evaporators; crystallizing.-Liquids or solutions are evaporated or concentrated by passing them in a transverse direction over a plurality of heated or cooled troughs or undulations, while subjected to an agitating or mixing.operation. Liquid is fed in through a funnel 3 and valve 5 to the first trough 1 of the upper bank A, and overflows from one trough to the next until it reaches the extreme left where it is delivered into the lower bank B, which it traverses in the opposite direction as far as the exit shoot 9. The passage of the liquid is assisted by revolving stirrers 8. The troughs are heated by means of hot gas, vapour, or liquid introduced into the spaces 2 bv pipes 25, 26, serving the upper and lower tiers respectively. When used for crystallizing, the troughs may be cooled. Air is admitted at inlets 20 to carry away evaporated moisture through outlets 21.

Abstract: 855,911. Electric analogue calculating systems. BRITISH THOMSON-HOUSTON CO. Ltd. Dec. 14, 1956, No. 38277/56. Class 37 A circuit arrangement which accepts both an electrical and a mechanical input and delivers an electrical output which is directly porportional to the product of the electrical input and a sinusoidal function of the mechanical input comprises a high gain amplifier which has a positive voltage feed back path of constant resistance and a negative voltage feedback path which includes a linear potentiometer, viz. a potentiometer uniform linear of angular motion of the slider of which produces a uniform change in the value of the resistance between either terminal of the potentiometer and the slider, the potentiometer being connected in series in the path between the slider on the one hand and the two terminals connected together on the other, and the values of the resistances being so chosen that with constant electrical input the output is approximately sinusoidally related to the movement of the slider within a limited range. With the arrangement in its simplest form the range extends between two successive zeros of a sinusoidal law, but by providing the amplifier with a push-pull output stage, and connecting across the output terminals a second linear potentiometer, the slider of which is mechanically coupled that of the first, the output being taken from the slider of the second potentiometer, the law can be made to range through zero. If the potentiometers have circular closed-circuit windings with diametrically opposite tapping points the law has no limits. Fig 1 shows such an arrangement the values of resistances 9, 13, 14, 15 being chosen so that the voltage gain differs from the sine law by a very small amount, say less than 25 x 10- <SP>5</SP>. The methods of choosing the values of the resistances are discussed in the Specification.
