Patent CA-2111679-A1 (CA)
Title: Active superconducting devices
Inventor: SUN JONATHAN Z
IPC: H01P1/203
Filed: 1992-06-17
Abstract: Active superconductive devices are formed having a variable conductive element in electromagnetic contact with a superconductor.  In one embodiment, a variable ohmic conductive device (16) such as a photoconductor, is placed adjacent a superconductor (12). By varying the optical radiation on the photoconductor, the electromagnetic environment adjacent the superconductor is changed, resulting in changed electrical properties. The superconductor may be patterned as a reject filter (10, 12, 14) with a photoconductor forming a microwave switch. Alternatively, a delay line (40) plus variable ohmic element (46) forms a phase shifter.

Title: Method and composition including particular additive for hydraulic cement with high fly ash content
Inventor: PILDYSH MIKHAIL
IPC: C04B7/24
Filed: 1995-04-21
Abstract: The invention is related to a hydraulic cement composition with a substantial part of the cement being replaced with fly ash. In order to increase the rate of the strength gain as well as the freeze-thaw scaling durability of such concrete material, a particular additive is used in very small quantities (from 0.2% to 1% of the weight of the cementitious materials in the mix), said additive comprised of finely ground amorphous carbon derived from wood or wood coal after driving off volatile substan-ces from the wood or wood coal by heat under relatively low temperatures in an oxygen depleted environment. The above additive is further enhanced by a protein powder, for instance, dried animal blood, for air entrain-ment purposes, which effect is further enhanced by an alum (aluminum sulphate) supplement.

Title: Speech coding device
Inventor: OZAWA KAZUNORI
IPC: G10L25/12
Filed: 1995-07-28
Abstract: A speech coding device capable of delivering a speech signal of excellent sound quality at a low bit rate is disclosed.  The disclosed device is character-ized by a method of calculating lag corresponding to pitch period and a speech signal coding method.  Lag is calculated as follows:  A speech signal is divided into frames; one frame is divided into a plurality of subframes; for each frame, subframes in which lag of a speech signal is expressed in the form of a differen-tial relative to lag of a previous subframe and subframes in which lag is expressed in the form of an absolute value, i.e., the lag value itself, are estab-lished; a plurality of bit allocation patterns are established for each frame that allocate bits for expressing lag as an absolute value or a differential in each of the plurality of subframes; for each bit allocation pattern, pitch predictive distortion is calculated for every subframe; accumulated distortion is calculated by accumulating the pitch predictive distortion over a predetermined plurality of subframes in the frame; a bit allocation pattern is selected so as to minimize the accumulated distortion.  The lags in the subframes of the selected pattern are determined as the lags in the subframes of interest.
