Title: Lipid prodrugs for oral administration
Inventor: HOSTETLER KARL Y
IPC: C07F9/38
Filed: 1993-12-15
Abstract: The oral delivery of many classes of drugs is facilitated by converting drugs having suitable functional groups to 1-0-alkyl-, 1-0-acyl-, 1-S-acyl, and 1-S-alkyl-sn-glycero-3-phosphate derivatives. The method confers the ability to be absorbed through the digestive tract to drugs that are not orally bioavailable in the non-derivatized state, and enhances the effectiveness of drugs that are poorly absorbed or rapidly eliminated. The method provides orally bioavailable lipid prodrugs of pharmaceutical compounds having diverse physiological activities, including anticancer and antiviral agents, anti-inflammatory agents, antihypertensives and antibiotics. Potency of the lipid prodrugs is comparable to that of the corresponding non-derivatized drugs.

Title: Picture data recording and/or reproducing apparatus
Inventor: YANAGIHARA NAOFUMI
IPC: H04N19/50
Filed: 1995-11-06
Abstract: A recording/reproducing apparatus for reproducing recorded encoded picture data from a recording medium in varying speed without picture disruption.  The recorded picture data are read from the recording medium and stored in a buffer memory.  A detection circuit detects a picture header in the stored picture data and, depending upon the results of such detection, may or may not supply a clock signal therefrom.  If a picture header is not detected, the detection circuit supplies the clock signal to the buffer memory and the delaying circuit.  In response thereto, the stored picture data are read out from the buffer memory and supplied to the delaying circuit so as to be delayed by a predetermined amount prior to being supplied therefrom.  If a picture header is detected during varying speed reproduction by the detection circuit, the clock signal is not supplied to the buffer memory and the delaying circuit, whereupon the delaying circuit outputs "0"s for a predetermined time period.

Abstract: A process for producing molten pig iron uses direct reduction of iron ore in a pre-reduction stage followed by a final reduction stage. In the pre-reduction stage iron ore is pre-reduced in a melting cyclone (1) by means of a reducing process gas originating from the final reduction stage. A post-combustion occurs in the reducing process gas in the melting cyclone so that said iron ore in said melting cyclone is at least partly melted. The partly melted iron ore passes downwardly into a metallurgical vessel (4) situated beneath the cyclone in which the final reduction takes place by supply of coal and oxygen, thereby forming a reducing process gas. A partial post-combustion occurs in the reducing process gas in the metallurgical vessel by means of said oxygen supplied thereto. The post-combustion ratio of the gas on exiting the metallurgical vessel is not more than 0.55. The coal is supplied directly into the slag layer (7) so that said partial post-combustion in said metallurgical vessel is at least partly effected in the slag layer. <IMAGE>

Abstract: A communications network protection design method in which a spare is notionally added to the network for a simulated span failure and the respective values for network restorability merit, as defined herein, are calculated. The notionally added spare having the greatest value of restorability merit is addedto the network design and the process repeated, being extended to add two spares at a time if need be, and finally to add a complete path of spares to restore a failed span, the process ending after any addition of a spare or spares for which a network restorability target is reached. Following this forward synthesis phase, a tightening phase reduces the network cost by trying to remove spares and checking whether the restorability target can still be met. When no further single spares can be removed without violating the restorability target, this phase proceeds through various combinations namely: removing one spare and adding one spare; removing two spares and adding one or two spares; and removing three spares and adding two or three spares. Each such combination is accepted only it if will reduce the network cost.

The device (10) comprises, aligned with one another within a vertical fiber drawing plant: a fiber drawing oven (11) in which is drawn, in a conventional and known manner, a preformed fiber (12) with an optical core (not shown) having the same composition as and a diameter greater than the core (2), enclosed in an optical sheath (not shown) having the same composition as and a thickness greater than the optical sheath (3), the diameter ratio of the optical sheath to the optical core of the preformed fiber (12) being the same as the diameter ratio of the optical sheath (3) and the optical core (2); a reactor (14) for depositing the non-crystalline carbon layer (4) on the bare optical fiber (13); a reactor (15) for depositing the boron amorphous layer (5); means (16) for controlling the diameter of the fiber at the reactor outlet (15); resin-coating means (17) for forming the resin layer (6) on the boron layer (5); a device (18) for polymerizing, with ultraviolet radiation, the resin layer (6); means (19) for controlling the final diameter of the fiber (1) obtained; a reel (20) for winding the finished fiber (1). The boron layer is applied to the carbon-coated optical fiber through the reduction of boron halide, for exemple, gaseous boron chloride, with gaseous hydrogen, based on the following equation: 2BCl¿3? + 3H¿2? ? 2B + 6HCl. The boron coating is hence applied by chemical vapour deposition. The reduction takes place at a temperature of about 1150 ~C, the boron chloride/hydrogen molar concentration ratio being close to 1/4. The carbon and boron deposits are applied, preferably, at a pressure close to atmospheric pressure, especially when they are deposited within the fiber drawing process, so as to enable open reactors to be used for fiber inlet and outlet.
