Patent TW-279975-B (TW)
IPC: H04B1/66
Filed: 1994-03-02
Granted: 1996-07-01
Abstract: A technique for recording, reproducing, transmitting and/or receiving compressed data utilizes frequency dividing filters (101, 102) for dividing the frequency range of digital signals into plural frequency bands, orthogonal transform circuits (103-105) for producing signal components in plural two-dimensional blocks along time and frequency, an adaptive bit allocation and encoding circuit (108) for quantizing and compressing the information for each two-dimensional block, and a bit allocation and calculating circuit (107). When recording the information together with information compressing parameters for each two-dimensional block, the information compressing parameters for at least two two-dimensional blocks are recorded collectively to avoid complexity in the structure of the sampling frequency signal generating circuits or the like that would otherwise be caused in the case of providing plural sampling frequencies, as well as to prevent an increase in hardware scale.

Title: Saw blade tooth form and method therefor
Inventor: DANIEL J CARLSEN
IPC: B23D61/14
Filed: 1994-09-02
Granted: 1996-02-01
Abstract: A saw blade has a plurality of teeth with each tooth formed by a beveled gullet forming a tralling face, a beveled gullet forming a leading face and a planar surface forming a curved cutting face. The gullets forming the tralling face and the leading face are beveled in opposite directions. The planar surface is generally parallel to the beveled trailing face. The unique tooth profile provides a saw tooth having a positive rake angle to significantly improve the strength of the tooth. The method of manufacturing of the unique tooth profile begins by orienting a saw blade blank about three axes and performing a first grinding operation which forms every other tooth gullet and every other planar surface. The partially formed blank is then oriented about two of the three axes in an opposite direction and a second grinding operation is performed. The second grinding operation grinds the remaining gullets and planar surfaces. The unique tooth profile of the present invention is applicable to jigsaw blades, linear edge saw blades and circular saw blades as well as the various types of bi-metal saw blades.

Abstract: In a process for accelerating the setting and hardening of a material which contains a hydraulic binder or which consists of a hydraulic binder there is used a setting accelerating mixture which is free of alkali metals and free of chlorides. Said setting accelerating mixture contains at least one water soluble sulfate of a polyvalent cation and a further constituent which is selected from the group consisting of calciumaluminate, calciumsulfoaluminate, basic aluminum salts, mixtures thereof or mixtures containing at least one of said constituents and a further component. If the water soluble sulfate of the polyvalent cation is aluminumsulfate then said compound has to contain crystal water in order to provide the water solubility of said product. With the setting accelerating mixtures a fast gaining of strength of a corresponding mortar or concrete is achieved and the finally hardened product has better mechanical characteristics than corresponding products prepared without the adding of any set accelerating admixture.

Granted: 1996-11-21
Abstract: Sulfur oxides (SOx) are scrubbed from combustion effluents with aqueous limestone slurries with greater efficiency due to the use of an improved entrainment separator (130). In the preferred embodiment of a single-loop, counter-current limestone wet scrubber (100) (preferably with a spray-contacting zone of less than 6 meters in height) operating at bulk gas flow rates of greater than 4.5 meters per second, a vertical stream of flue gas is freed of a substantial portion of slurry droplets and diverted for effective mist removal by a well-drained, horizontal-flow mist eliminator (140). The entrainment separator (130) is a single-pass device with individual blades aligned for effective operation with reduced droplet impingement on the upper walls (e.g., roof) of the scrubber and to permit periodic washing. Use of a vertically-oriented, horizontal-shaft rotary heat exchanger (431) is facilitated and space and duct work requirements are greatly reduced.

Title: FM demodulator with threshold extension and receiver comprising such an FM demodulator
Inventor: WOLFDIETRICH GEORG KASPERKOVIT
IPC: H03D3/06
Filed: 1995-07-14
Granted: 1996-02-01
Abstract: The FM demodulator having two input terminals (11, 12), to which FM input signals having 90 deg. phase relation are applied, the FM demodulator comprising a phase comparator (1) and tunable phase shifting means (2), the phase shifting means (2) being tuned by the FM demodulator output signal via a feedback path comprising a loop filter. By adding a compensation filter (5) to the tuning control loop the phase shifting means is effectively cancelled from the tuning control loop, thereby making the tuning control loop independent of the bandwidth of the phase shifting means (2). Thus the bandwidth of the phase shifting means (2) can be reduced for threshold extension.
