Title: Feeder made from exothermic heating composition for castings
Inventor: SCHERER MANFRED
IPC: B22C9/08
Filed: 1985-12-12
Abstract: A feeder consisting of exothermic heating composition keeps the cast material disposed in the feeder liquid until completion of the shrinkage feed of the casting. To avoid contamination of the moulding sand (2) on separation of the casting (1) due to burnt feeder disintegrating into irregular fragments, the make-up of the heating composition is so chosen that the heating composition during the shrinkage feed sinters together and the burnt feeder is given such a high strength that it can be detached as a whole or in large pieces capable of being sieved out. Various ways in which the constitution of the heating composition is adjusted to achieve sintering at the temperature reached are described with examples of constituents. <IMAGE>

Title: Electrochemical detection of redox species produced or released from macromolecules
Inventor: MC NEIL CALUM JACK
IPC: C12Q1/26
Filed: 1986-02-21
Abstract: Use of an electrochemical detection of redox species (MR) in a medium to determine the occurence of a condition under which such species are produced or released, wherein such production or release is enabled by the digestion or disruption of a macromolecular species (An). The invention provides a method of assay for a polymer, for a depolymerase enzyme, and for a labelled specific binding agent, in which a polymer (An) is labelled with a component of a mediator/enzyme/substrate system which remains inactive until released into solution. Electrodes in the medium determine the occurence of a condition under which redox species are produced by the mediator/enzyme/substrate system or released into solution. Where the mediator activity of, for example ferrocene to glucose oxidase is used an amplification step is provided.

Title: Maintaining an engine in a state ready to start
Inventor: KHAN RAKIB
IPC: F02N11/08
Filed: 1988-01-11
Abstract: A device which controls automatically the starting of a single or multiple gas, gas-diesel or diesel engine comprises a temperature sensor, (D1, D2) a vibration sensor (MP), and a motion sensor (MS). The temperature sensor is used to turn the engine on and off based on predetermined maximum and minimum temperatures to prevent the engine from getting too cold. For multiple engines this sensor can be used to start a secondary engine if the primary engine reaches a predetermined maximum temperature; and to revert when the primary engine's temperature drops to predetermined low temperature. The vibration sensor (MP) is used to analyze the engines activity. For multiple engines, the vibration sensor makes the decision to switch from the primary to the secondary engine or vice versa. The sensor (MP) alo determines the cranking time for both multiple and single engines. The motion sensor (MS) is used for an automobile to turn off the engine should the vehicle move. The device allows several attempts to start the engine, changing engine parameters each time. If the engine does not start after a predetermined number of attempts then the device is disabled. It will reset when the engine finally is started. For a single engine, a clock can bypass the device to maintain a ready-to-drive condition while maintaining a ready-to-start temperature. <IMAGE>

Title: Pre-formed sheet material for small scale manufacture
Inventor: LAWRENCE TUI MARGARET
IPC: B29C53/06
Filed: 1988-02-11
Abstract: The sheet preferably of metal, but alternatively of plastics or composite material, has a pattern of lines and circles etched or electrochemically milled or otherwise formed, e.g. cast or plastically deformed, to such a depth as to considerably weaken the material where so inscribed. The pattern is regular with parallel or intersecting lines and circles between the lines or at the intersections with regular spacing. The material can be used to fabricate a variety of items normally made from sheet metal, but without the need for skilled marking out, cutting, bending and drilling. Using minimum force, simple punches can make holes and cut outs and precise bends can be folded provided that the material is only deformed where the pattern is inscribed. Finished or part finished items manufactured from the inscribed sheet material can be reinforced by covering the patterned surface with thermosetting plastics material. <IMAGE>

Title: Production of labelled organic compounds
Inventor: KERBY DR NIGEL WELLS
IPC: C12P1/00
Filed: 1988-06-29
Abstract: Isotopically labelled organic compounds (e.g. amino acids and sugars) are obtained in a biological photoproduction process comprising the step of culturing, in a culture medium containing at least one simple labelled inorganic nutrient, a mutant drain of photosynthetic prokaryotic or eukaryotic species selected from cyanobacterial or microalgal species which are capable of producing a said organic compound, and recovering labelled organic compound produced by the mutant strain from the culture medium. Thus with the present invention it is possible to achieve continous production of isotopically labelled organic compound over a extended period of time using relatively simple and hence inexpensive feedstuffs.

Title: Method and apparatus for sampling the gaseous content of liquid
Inventor: ISSENMANN OLIVIER
IPC: G01N1/24
Filed: 1989-11-01
Abstract: A method for continuously sampling the gaseous content of a liquid also loaded with solids, in particular with hydrocarbons in drilling mud, consists in continuously drawing off, over a precisely predetermined period and as close to the well as possible, a predetermined quantity of mud, in transferring said predetermined quantity to a degassing chamber having a constant, accurately determined volume, in degassing said quantity completely over the said predetermined period, in drawing off the gases which are released from the predetermined quantity of mud, and in transporting the gases, immediately on leaving the degassing chamber, to an analysing and measuring device such as a flame-ionisation device. A device for performing this method is installed as close as possible to a well outlet and comprises a support frame (15) having a plate supporting a motor (21) connected to a reduction gear (20) driving a pump (19) whose inlet is connected to a flexible tube (28) for drawing off mud as it emerges from the well and whose outlet is connected to a degassing chamber (23). The degassing chamber (23) has a rotary degassing agitator directly connected to the drive shaft of the motor (21) and a gas-evacuation tube (25) leads from an upper part of the degassing chamber (23) through a collecting tube (26) to an analysing device. A flexible tube (22) leading from the lower part of the degassing chamber (23) allows the degassed mud to pass out of the chamber (23). <IMAGE>
