Patent ZA-821079-B (ZA)
Title: Expression of polypeptides in yeast
Inventor: HITZEMAN RONALD A
IPC: C12N1/16
Filed: 1982-02-18
Abstract: In order to make a yeast strain capable of expressing a desired polypeptide (e.g. leukocyte interferon D) which it does not normally make or use, it is transformed with an expression vector. This is obtained by producing a transfer vector which has respective origins of replication and phenotypic selection genes derived from both bacteria and yeast, and inserting into it DNA fragments: (i) coding for the desired polypeptide and (ii) comprising a yeast-derived promoter. The insertion is effected so that 'start' and 'stop' signals are provided, and these and the promoter can control expression of the polypeptide, and so that the replication origins and phenotypic selection genes of the transfer vector are still functional. Thus the expression vector and its precursors can replicate, and their presence can be recognised, both in yeast and bacteria. Bacteria are used for amplification. The yeast-derived phenotypic selection gene may complement a mutation carried by the strain to be transformed.

Title: Device for protecting metal objects situated in the environment of an intense magnetic field developed by an alternator rotor without a stator
Inventor: DELASSUS JEAN
IPC: G01M15/00
Filed: 1982-08-24
Abstract: The protection device comprises two half cages (13, 14) superposed on each other and surrounding the rotor (8) under test. The half cages together constitute a cage with openings between its bars and provided with water cooling in said bars. The cage ensures that the magnetic field generated by a rotor under test with excitation current is stopped within a distance equivalent to the size of the holes between the cage bars. Induced current heating in the cage is kept under control by water cooling, and metal objects outside the cage are substantially protected from the magnetic field by the cage. Air can pass freely through the cage, and the rotor can be observed without removing the cage.

Title: Method of and arrangement for synchronising the receiver arrangements in a digital multiplex transmission system
Inventor: EIZENHOEFER ALFONS
IPC: H04J13/00
Filed: 1986-03-19
Abstract: A digital multiplex radio transmission system wherein transmission channels between a fixed radio station and a plurality of mobile radio stations may be established by code division multiplex or frequency division multiplex, individual message channels being separated by means of different distributions of the data symbols transmitted therein. In order to synchronize the fixed station transmitter with the mobile station receivers, respective synchronizing symbols are inserted between the successive data symbols transmitted in any channel. The synchronizing symbols used in all channels are the same, and are spaced at the same time intervals in each channel. Consequently, they are received with significantly higher energy than the data symbols, permitting the multi-path profile to be measured and providing reliable synchronization.

Title: Apparatus and two stage method for substantially reducing can spacing and speed to match those of deco chain pins
Inventor: WILLIAMS ROBERT
IPC: B65G47/86
Filed: 1992-10-09
Abstract: A continuous motion cylindrical can decorator is provided with mandrels that receive undecorated cans and a deco chain that carries decorated cans through a curing oven. The mandrels are mounted along the periphery of a continuously rotating carrier. Chain speed is much slower than linear mandrel speed and spacing between pins on the chain is much less than spacing between mandrels. Interposed between the chain and the mandrel carrier is a continuously rotating transfer carrier having a plurality of suction holding devices thereto. As the holding devices move through a transfer region they are in single file and receive cans that are blown from the mandrels. In the transfer region mandrel linear speed is substantially greater than linear speed of the holding devices, and spacing between the latter is much less than spacing between mandrels As the loaded suction holding devices move downstream through a pickup region cans thereon are loaded on two rows of pins carried by the deco chain. Linear speed of the holding devices while moving through the transfer region exceeds chain speed, and in this region the holding devices are spaced apart by a distance that exceeds pin spacing. By the time the holding devices reach the pickup region they are arranged in two rows, are spaced apart and are moving at a speed such that they essentially track the moving pins while the latter are being loaded.

Title: Process for the production of molten pig iron or molten steel pre-products and sponge iron and a plant for carrying out the process
Inventor: DIEHL JOERG
IPC: C21B11/00
Filed: 1995-10-16
Abstract: Liq. pig iron or steel is produced by adding iron ore in pieces or pellets together with additive into a redn. zone (12) where sponge iron is produced which is then fed into melting zone (8) with carbon and O2-contg. gas. A CO-contg. and H2-contg. redn. gas is produced and passed back to the redn. zone (12) where it is converted to an export gas which is drawn off and subjected to a CO2 eliminating process before being passed to a further redn. zone (21) for direct redn. of more iron ore. A part of the redn. gas produced in the zone (8) is drawn off and fed directly to the zone (21), by-passing the CO2 elimination stage. The plant for carrying out this process is also claimed.

Title: Syringe pumps
Inventor: TRIBE ROBERT JAMES
IPC: A61M5/145
Filed: 2001-08-02
Granted: 2004-04-07
Abstract: A syringe pump has a motor (9) rotating a leadscrew (8), which drives a plunger head retainer (10) to push a plunger (35) along the barrel (30) of a syringe (3) so as to dispense medication to a patient. A force sensor (20) in the head retainer (10) measures the force on the plunger (35) to detect when there is an occlusion restricting flow of medication. When an excess force is detected an alarm is generated and the motor (9) is reversed to reduce the force to about 10% of that at which the occlusion is detected. The occlusion can be removed with a reduced risk of a bolus of medication being dispensed after which the user restarts the pump so that the plunger (35) is driven normally. <IMAGE>
