Title: Agent for inhibiting cell growth
IPC: C07H13/04
Filed: 1977-02-04
Abstract: The compounds correspond to the formula: <IMAGE> in which R2 represents the radical of a purine or pyrimidine base. They are prepared by converting uridine via 2'-azido-2'-deoxyuridine, 2-azido-2-deoxyribose, its 1-O-methylglycoside and the corresponding 3,5-diacetate into 1-O-methyl-2-azido-2-deoxyribose 1,3,5-triacetate, reacting the triacetate with a purine or pyrimidine base whose primary amino group is acylated, and eliminating the acyl group. The resulting compounds can be separated into the  alpha  and  beta anomers. They are furthermore converted into the 2'-amino-2'-deoxy derivatives, into the 5'-phosphates and into the 2'-amino-5'-phosphates. The compounds inhibit the synthesis of the deoxyribonucleic acids and cell growth; they are suitable for the treatment of ulcers and, in particular, cancer, but also represent intermediates for the preparation of medicaments for cancer and viral infections.

Abstract: 1,098,395. Tuning arrangements. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Feb. 4, 1965 [Feb. 7, 1964], No. 4880/65. Heading H3Q. A turret tuner with a fine tuning device has a disc rotatable with the tuner and bearing a cam for each tuning position, each cam being made of synthetic thermoplastic material and integral with a shaft which passes through a hole in the disc and a setting adjuster on the other side of the disc. In Fig. 1, the disc 5, which also carries coils 9 and contacts 11, has a number of holes near its periphery, each hole containing a shaft 13 with setting means 29 on one side and an eccentrically mounted rod 15 on the other side. As the tuner shaft 1 is rotated by the knob 53 each rod 15 in turn at the corresponding tuning setting raises a bar 17 which rooks an arm 20 and adjusts the slider of a tubular capacitor 25 (details in Fig. 2, not shown). The fine tuning adjustment is made by knob 51 which is fastened to a sleeve 45, gear 43 and bracket 37. The latter carries a shaft 35 on which is a gear 41 meshing with the gear 43. When the knob 51 is pushed in against a spring 47, the end 33 of the shaft 35 engages the setting means 29 so that rotation of the knob 51 adjusts the angular position of the eccentric 15. The shaft 13 is a tight-fit in the disc 5 so that the fine tuning setting for each tuning position is retained when the shaft 1 is rotated. The parts 13, 15 and 29 can be made in situ by placing the disc 5 in a moulding jig and spraying material into the mould. If a material is used which shrinks on cooling, the parts 15 and 29 are held tightly against the disc to increase the friction. The parts 13, 15 and 29 can be mounted on a separate disc outside the housing 3. The knob 51 can be dispensed with if the knob 53 is axially movable to engage and disengage the shaft 1 and sleeve 45. Reference has been directed by the Comptroller to Specifications 906,816 and 913,382.

Patent GB-698246-A (GB)
Title: Device for the fractional distillation of liquids
Inventor: COOKE EDWARD VINCENT
IPC: B01D3/30
Filed: 1950-03-03
Abstract: Fractional distillation, particularly at low pressures (1 to 20 m.m.), is effected by passing the vapours from the still upwards through a helical passage element which is rotated about an axis inclined to the vertical, condensing the vapours leaving the upper end of the element, and <PICT:0698246/III/1> returning part of the condensate to the element as reflux.  The speed of rotation is adjusted so as to ensure that the reflux is not thrown off the upper surface of the helical passage by centrifugal force, but moves downwards by a screw-like action, the whole of the upper surface of the element being wetted.  In the apparatus shown, the element comprises helical fin a forming a passage bounded by concentric cylindrical walls c and d, the angle a between wall d and the upper surface of the fin being less than 90 degrees.  The element is secured by flanges f1 and f2 to shaft e, and is mounted for rotation in shell s, which is closed by end-flanges h1 and h2.  The shaft e is inclined at an angle (90-a) to the vertical.  Flange h2 carries a boiling-coil j with connections through the flange for heat transfer fluid.  The distilland is introduced into, and removed from, the boiler through pipe o.  The boiling liquid is stirred by paddle p which is attached to shaft e.  Flange h1 carries a condensing coil i with connections through the flange for coolant liquid.  Some of the condensate is collected in tundish t, and is withdrawn from the apparatus by a pipe passing through the shell.  The remainder of the condensate falls as reflux on to the upper surface of the upper most turn of the helical fin.  The shell may be evacuated through pipe l. The cylindrical wall c extends to below the level of the liquid in the boiler nearly as far as flange h2, thus forming a seal which prevents the direct escape of boiling vapour from the boiler between the shell s and cylinder c to the condenser.  In a modification, the outer cylindrical wall c may be omitted, and the helical passage element is then made a working fit in shell s. The apparatus is characterized by low pressure-drop and low liquid-hold-up, and by high-efficiency at low rates of through-put.  The upper surface of the fin may be roughened or otherwise provided with small projections, in order to increase the area of the wetted surface and to increase the fractional resistance of the vapour.  The fin may be constructed of material that is sufficiently porous to allow some, but not all, of the reflux liquid to seep through the fin.  When the apparatus is used for continuous distillation, provision is made for introducing the feed to some part of the helical passage element between its upper and lower extremities, and, if required, for withdrawing side-streams from the element.  The element may be caused to rotate in any convenient manner.  The Provisional Specification states that the element may be rotated by an electromagnetic device or, alternatively, by a turbine mechanism operated by means of the head of reflux returning from the condenser.
