Abstract: The invention concerns homogeneous at least partial sterilisation or homogeneous complete pasteurisation of a substrate. In a first step of the method, the substrate is loaded via a loading area of a sealed hollow vessel at a first end of the vessel. A fluid for moistening said substrate may be introduced into the vessel, the vessel being further provided with means for at least partly sterilising or pasteurising the moistened substrate. In a second step, the substrate is passed through a bounded zone of transport towards the front of the machine until it reaches the other end of thereof. In a third step, the substrate is passed through a zone of transport towards the rear of the vessel so as to return the substrate to the first end, the zones of transport towards the front and towards the rear being separated from each other by a tubular partition. During the return transport the substrate may be subjected to tumbling. The second and third steps are repeated as many times as necessary to obtain homogeneous and at least partial sterilisation or homogeneous and complete pasteurisation of said substrate. A machine is also described for carrying out the method. Application to sterilising or pasteurising organic substrate such as growth media for plants or mushrooms.

Title: Continuous liquid flow system
Inventor: WATLING DAVID
IPC: G01G11/16
Filed: 2001-03-15
Abstract: The disclosure relates to a system for continuous delivery of a measured flow of liquid to a processing apparatus comprising a reservoir (10) for holding a bulk supply of the liquid and, an intermediate vessel (12). A first pump delivers liquid from the intermediate vessel to processing equipment at one rate. A second pump (13) delivers liquid from the reservoir to the intermediate vessel of a second much faster rate. A pressure transducer (14) continuously monitors the weight of the liquid in the vessel and controls the first pump accordingly to deliver the required weight of liquid at the required rate to the processing equipment. The pressure transducer determines when the weight of liquid in the intermediate vessel has reached a minimum position to initiate operation of the second pump (13) to refill the vessel and a further device terminates operation of the second means when the liquid level in the vessel reaches a maximum position.

Title: Interconnect circuit between non-compatible oximeter and sensor
Inventor: CHEW BRADFORD B
IPC: A61B5/00
Filed: 2001-09-21
Abstract: An oximeter sensor adapter which allows a sensor without a resistor in parallel with its LEDs to operate with an oximeter expecting such a resistor in parallel. The adapter has a switching circuit which has inputs connected to the LED drive outputs of the oximeter. The switching circuit has two pairs of outputs, one connected to the LED drive lines of the sensor, and the other connected to a resistor in the adapter itself. The switching circuit is controlled by a sensing circuit which senses when a signal on the input lines drops below a predetermined level, such as 0.5 volts. The sensing circuit, in response to a low voltage (corresponding to an attempt to read a resistor in parallel with the LEDs), will provide a signal to a switching circuit. The switching circuit will switch the resistor onto the input lines so that it can be read. When a higher voltage returns to the input lines, the switching circuit switches back to the LEDs themselves.

Title: Preparation of non-crystalline atorvastatin calcium
Inventor: SORSAK GORAZD
IPC: A61P3/00
Filed: 2002-01-22
Abstract: Atorvastatin calcium, the substance known by the chemical name [(R-(R*,R*)]-2-(4-fluorophenyl)-b,ddihydorxy-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic acid hemi calcium salt is known as HMG-CoA reductase inhibitor and is used as an antihypercholesterolemic agent. Atorvastatin is usually prepared as its calcium salt since it enable atorvastatin to be conveniently formulated in the pharmaceutical formulations, for example, in tablets, capsules, powders and the like for oral administration. Atorvastatin calcium can exist in an amorphous form or in one of the crystalline forms (Form I, Form II, Form III and Form IV).  Atorvastating calcium is the substance which is very slightly water-soluble, and it has been found that the crystalline forms are less readily soluble than the amorphous form which may cause problems in the bioavailability of atorvastatin in the body. The present invention relates to a novel process for converting the intermediate in the synthesis of atorvastatin having the following formula (I) or atorvastatin lactose into the non-crystalline atorvastatin calcium: wherein A denotes a common protection group or separate protection groups for the dihydroxy group and B denotes a carboxylic acid protection group.
