Title: Paramagnetic organic compounds for therapeutic and
Inventor: WALTER MACH
IPC: H01F1/42
Filed: 1967-11-30
Abstract: Paramagnetic, organic compounds for therapeutic and diagnostic purposes are prepared by subjecting one or more of adrenalin, noradrenalin and dopamine to an oxidative radical-polymerisation regulated with the help of an electron spin resonance signal (ESR), using inorganic catalysts, pref. oxides, together with 3-methoxy-4-hydroxy-mandelic acid and/or 3-methoxy-4-hydroxyphenyl-glyoxylic acid and/or 3-methoxy-4-hydroxybenzoic acid and o-aminophenol and/or o-aminoquinone. The reaction product obtained is dried, taken up in an acidified, water-soluble organic solvent, absorbed on active carbon and eluted in the form of salts with water-containing bases. The free water-soluble acid is liberated from the salt form by electrodialysis or by cation exchange. The paramagnetic, semiquinoidal pyrocatechol polymerisates influence the intramitochondrial energy production or the biological use of energy of certain biological structures, esp. of the sympathico-chromaffin-adrenal system, e.g. paramagnetic acid adrenalin polymerisates are suitable for influencing therapeutically pathological equilibrium disorders of this system. The compounds are active in the field of cybernetic biochemistry (self-regulation) and may also be used for diagnostic purposes.

Title: Vehicle brake assembly having a anchor pin with a rubber layer
Inventor: BELLINGHAM RICHARD MARTIN
IPC: F16D65/09
Filed: 2000-12-18
Abstract: A brake assembly of a vehicle for enduring corrosive road effects includes a mounting bracket 12 having a bore 14. An anchor pin 18 extends through the bore of the mounting bracket to rotatably support a brake shoe 16 of the assembly. The anchor pin 18 includes first and second end portions 20,22 and an outer surface 24, and the brake shoe 16 rotates about the end portions 20,22 relative to the mounting bracket 12. A rubber layer 34 is disposed between the outer surface 24 of the anchor pin (the rubber being bonded to the surface) and the bore 14 of the mounting bracket 12 to permit rotation of the brake shoe 16 about the mounting bracket 12 in the event the brake shoe becomes corrosively bonded to the pin. In such an event, flexural stiffness of the rubber layer 34 enables rotation of the anchor pin 18 relative to the mounting bracket 12, and since the brake shoe 16 is bonded to the anchor pin 18, the brake shoe also rotates relative to the mounting bracket thereby maintaining operation of the brake assembly. A bushing 38 may surround an outer machined circumference of the rubber layer 34.

Title: Tunable capacitive load driver for electroluminescent lamp
Inventor: PURCELL MARK
IPC: H05B44/00
Filed: 2001-08-23
Abstract: An efficient power supply for driving a capacitive load, such as an electroluminescent lamp, which can be tuned either electronically or mechanically to resonate at different frequencies, and which can automatically compensate for ageing and temperature characteristics of the load. The driver consists of a parallel resonant LC oscillator circuit 14 that uses the load 7 as the capacitance part of the oscillator, and a variable inductor 8 as the inductance part of the oscillator. The electronically tunable oscillator can form a voltage controlled oscillator which can be included within a phase locked loop 4 to automatically lock itself to a known frequency irrespective of capacitive load. Part of the phase locked loop control voltage can be fed into the voltage output control stage 3 to compensate for the reduction of light output due to the ageing characteristics of an electroluminescent lamp. This is done by gradually increasing the output voltage as the EL capacitance falls so as to keep the light output constant. In addition changes in capactitance due to variations in ambient temperature can be conpensated for, and the frequency hence colour of the emitted light automatically kept constant. The output voltage to the load 7 is isolated and fully floating, and can be referenced to a fixed voltage (usually ground) to prevent excessive voltage excursions. The driver exhibits inherent soft start and soft shutdown characteristics to eliminate high voltage spikes on power up or power down. The inductance and capacitance of the parallel resonant circuit acts as a filter to remove any high frequency content.
