Patent CA-2052178-A1 (CA)
Inventor: IQBAL MOHAMMAD
IPC: C08L71/02
Filed: 1991-09-24
Abstract: This invention relates to transparent materials that are capable of absorbing liquids, and, more particularly, to materials that can be used as ink-receptive layers for transparent imageable materials. Transparent materials that are capable of absorbing significant quantities of liquid, while maintaining some degree of durability and transparency, are useful in contact lenses, priming layers for coatings coated out of aqueous solutions, fog-resistant coatings, and transparent imageable materials for use with mechanized ink depositing devices, such as pen plotters and ink-jet printers. Compositions useful as transparent liquid absorbent materials have been formed by blending a liquid-insoluble polymeric material with a liquid-soluble polymeric material. A problem that frequently arises in the formulation of polymer blends is the incompatibility of the polymers being blended. When attempts are made to blend polymers that are incompatible, phase separation occurs, resulting in haze, lack of transparency, and other forms of inhomogeneity. This invention provides semi-interpenetrating polymeric networks comprising a blend of hydrophilic and hydrophobic polymers wherein at least one of the polymeric components is crosslinked after blending to form a continuous network throughout the bulk of the material, and through which the uncrosslinked polymeric components are intertwined in such a way as to form a macroscopically homogeneous composition. The integrity of such networks persists even after absorption of solvent.      These materials can be used to form durable, non-tacky, ink-absorbent, transparent coatings for graphical materials.

Title: Steroid eluting intramuscular lead
Inventor: GRANDJEAN PIERRE-ANDRE
IPC: A61M60/289
Filed: 1990-12-04
Abstract: An improved lead (100) for electrically stimulating muscle tissue particularly configured for a cardiac assist system powered by surgically modified skeletal muscle tissue. The skeletal muscle is either wrapped about the heart itself, or about an auxiliary pumping chamber attached to the aorta. Electrical stimulation is supplied via the improved lead (100) to cause contraction of the skeletal muscle in synchronism with the natural or artificially paced heart rate and timed to obtain the desired hemodynamic effect.  The improved lead (100) has an electrode (114, 124) which is embedded in the skeletal muscle. The stimulation threshold of the skeletal muscle is held relatively low by the action of a glucocorticosteroid imbedded within the suture material (120). By placing the drug material in this position, it acts as an anti-inflammatory along the entire path of the suture material (120) and treats the specific area of electrode contact from within the muscle itself. The specific area of electrode contact may also be treated from the electrode side by placing a similar drug within the electrode (124).

Title: Method of and apparatus for controlling modulation of digital signals in frequency modulated transmissions
Inventor: KOENCK STEVEN E
IPC: H04L1/16
Filed: 1991-01-18
Abstract: A signal amplitude shaping circuit (31) is interposed between a signal source (32) and a signal input terminal (16) of a frequency modulation circuit of a typical voice radio transmitter or transceiver unit. The amplitude shaping circuit (31) includes a high-impedance sampling circuit (34) which senses the steady state bias voltage at the signal input terminal during periods when no data are being transmitted. Upon receipt of a transmit-enable signal (53), the most recently sensed bias voltage is stored and positive and negative offset voltages (74, 69) are generated with respect to the stored voltage (40). One of the offset voltages (74, 69) is adjusted as a precisely determined voltage with respect to the stored voltage (40). The other of the offset voltages (69) is generated by inverting the first, adjusted voltage, such that the two offset voltages (74, 69) are offset by equal values in opposite directions. An analog switch (46) is adapted to receive a sequence of digital signals and to apply the positive and negative offset voltages (74, 69) to the signal input terminal in a sequence corresponding to the binary signal sequence of the received data signals.
