An electrode (10) adapted to be utilized within the external ear canal (46) for applying/recording electrical signals to/from the neural/neuromuscular system of a person having an external ear canal (46) and adjacent tympanic membrane (48). The electrode (10) utilizes an elongated flexible body (12) having a proximate end (14) and a distal end (16). A compressible material (18) is mounted at the d...

A monomer sequence, which is a topographical equivalent of the ligand which is complementary to a particular receptor, which is of interest, is detected or determined by, 1. a plurality of catamers being synthesized, each catamer having the general formula: D2-D1, where D1 indicates a designated monomer selected from a first monomer group, and D2 indicates a designated monomer selected from a seco...

The output of a laser diode or L.E.D. is amplitude modulated by varying the forward current through it. This is done by applying a dc current component from a first current source and an ac current component from another part of the circuit. The ac current component is applied to the laser diode or L.E.D. via an ideal impedance matching transformer which includes the internal capacitance of the la...

A measurement and/or control device is used (2), in company with a coil indicator (7), a stator (3) in the form of a water-cooled base, a coil arrangement for signal transmission (11,12), and a drive arrangement in the form of a V-belt (18) or turbine wheel. Eddy-curents are used in the measuring and control process, with the movement of the indicator (7) relative to the test object (1) considered...

In the first stage, approximately equal pts. of natural fertiliser and neat are mixed together and the compost is left for about a year in a pile not more than three meters high. It is then redistributed and aerated and left again for a year. After possibly further storage and aeration, about 6% of commercial fertiliser and about 2% of peat mould would be added. The compost is finally left another...

A belt winding arrangement is provided, being spring-activated and lockable. It has two parts simultaneously wound on to a retarder. One of the parts has a free end which is attached to a person, and free end of the other part is connected to a base.
