Patent CA-2112892-C (CA)
Inventor: WIRTH JOHANNES
IPC: G01G11/00
Filed: 1993-04-06
Granted: 1999-12-21
Abstract: The bulk material, the amount of which is to be determined through second-integration or time-integration, passes over a top chute (2) onto a bottom chute (3) which defines the velocity of the bulk material. The bottom chute (3) channels the bulk material to a slide (4) which has the same angle of tilt as the bottom chute (3). The weight components of the amounts of bulk material on the slide (4) acting orthogonally along the direction of the slide (4) are determined by a load-sensing device (5). After passing down the slide (4), the bulk material impacts a vertically arranged deflector plate (6) which is rigidly connected to a connecting plate (8), with the deflector plate (6) at that point generating a force through its change in its pulse action which is determined by a second load-sensing device (7). The second load-sensing device (7) only measures the horizontal components of this change in pulse action, and, like the initial load-sensing device (5), is either parallel channeled or provided with parallel channeling.      Both load-sensing devices (5, 7) are connected via lines (11, 12) to a computer (13) which contains the evaluation formula and all relevant correction parameters stored in its memory. Both chutes (2, 3) and the load-sensing devices (5, 7) are supported by a frame (1). Once having been weighed the bulk material falls into a funnel (9).

Granted: 2003-05-27
Abstract: The present invention relates to a communications proto-cot for a digital telemetry system which enables more efficient digital data transmission between a plurality of digital commu-nications nodes: The protocol is implemented using uplink and downlink packets and superpackets. Each node forms an up-link packet which contains node data and protocols. Those packets are packaged into uplink superpackets and transmitted to a control node. Downlink superpackets containing informa-tion signifying which of the uplink superpackets were received correctly are formed and transmitted to the individual nodes. In response, any uplink superpacket received incorrectly is retrans-mitted. Additionally, the communications protocol also time stamps messages received from the nodes to provide for digital communications time correlation.

Title: Pear processing method and apparatus
Inventor: PATERSON DOUGLAS F
IPC: A23N7/02
Filed: 1994-03-22
Granted: 1998-12-15
Abstract: A pear processing method and apparatus is provided which includes several mechanisms for properly orienting the pear prior to coring, peeling and seed celling of the pear. Each pear is tumbled between a pair of orienting rolls to a position wherein the stem of the pear is oriented downwardly. Whiskers on one of the rolls speed up this orienting of the pear. A friction clutch on the other roll helps maintain the pear in its proper position, once the proper alignment has been attained. The pear is dropped downwardly into a transfer cup having four resilient fingers which tend to orient the pear.  The pear is then pushed out of the transfer cup downwardly into a feed cup having a concave receptacle for centering the stem of the pear and three upwardly extending arms which grasp and center the blossom end of the pear. The pear is then transferred to a station wherein the pear is cored and thereafter peeled and seed celled simultaneously. The stem and blossom are also trimmed. The pear is thereafter passed into a slice cup having a design which more effectively separates the waste from the processed pear.

Patent CA-2127297-C (CA)
Inventor: DOGUCHI KENTARO
IPC: H01L31/0224
Filed: 1994-07-04
Granted: 2003-11-18
Abstract: In an opto-electronic integrated circuit of the present invention, in a first surface region of a semiconductor substrate, a pin-type photodiode is constituted on the basis of a photodiode layer formed on a first transistor layer. In a second surface region of the semiconductor substrate, a hetero junction bipolar transistor is constituted on the basis of only a second transistor layer separated form the first transistor layer. Since a plurality of heterojunction bipolar transistors are normally integrated for one pin-type photodiode, the thickness of the heterojunction bipolar transistors larger in number than the pin-type photodiode is set regardless of the thickness of the pin-type photodiode. the thickness of a high-resistance layer in the pin-type photodiode is set with an increased degree of freedom. When the first surface region of the semiconductor substrate is the inner region of a recessed step portion, and the second surface region of the semiconductor substrate is the outer region of the recessed step portion, a difference in thickness between the heterojunction bipolar transistor and the pin-type photodiode is absorbed by the depth of the recessed step portion. For this reason, the pin-type photodiode and the heterojunction bipolar transistor are formed to have almost the same surface level.

Title: A low rate multi-mode celp codec that uses backward prediction
Inventor: SWAMINATHAN KUMAR
IPC: G10L25/93
Filed: 1995-12-18
Granted: 2001-02-13
Abstract: The present invention provides a multi-mode CELP encoding and decoding method and device for digitized speech signals providing improvements over prior art codecs and coding methods by selectively utilizes backward prediction for the short-term predictor parameters and fixed codebook gain of a speech signal.  In order to achieve these improvements, the present invention provides a coding method comprising the steps of classifying a segment of the digitized speech signal as one of a plurality of predetermined modes, determining a set of unquantized line spectral frequencies to represent the short term predictor parameters for that segment, and quantizing the determined set of unquantized line spectral frequencies using a mode-specific combination of scalar quantization and vector quantization, which utilizes backward prediction for modes with voiced speech signals.          Furthermore, backward prediction is selectively applied to the fixed codebook gain in the modes that are free of transients so that it may be used in the fixed codebook search and fixed codebook gain quantization in those modes.

Abstract: Modem throughput across a cellular mobile telephone network is increased by controlling the response of the modem to blank and burst orders. In the case of a power control order, the modem may be made aware of the fact that the channel has not changed. Significant performance gain in terms of channel throughput can then be achieved by avoiding a lengthy retraining procedure. The modem operation may be suspended during the blank and burst order and enabled after the blank and burst order, avoiding an unnecessary retrain procedure during the blanking period. In the case of a handoff, the modem may be directed to immediately perform a retrain procedure rather than wait for the long blanking period to be detected by the modem or the link access procedure.

Abstract: Briquette comprising silicon-containing residues as an additive for metallurgic purposes.          Silicon-containing residues, as they accumulate especially during the synthesis of organosilanes out of metallic silicon, and especially methyl chloride, are processed according to the invention to briquettes, being additives for the quality adjustment of cast iron being produced in a cupola furnace in order to avoid either costly regeneration for the recovering of the valuable components or the total dumping of said silicon-containing residues. Besides the silicon-containing residue the briquettes contain 1 - 10 percent by weight of cardboard fibre, 5 - 40 percent by weight of hydraulic cement and 0 - 20 percent by weight of additional additives having influence on the quality of the cast iron. The cement- and cardboard fibre-containing briquettes are mechanically and thermally sufficiently stable with respect to the operation of the melting furnace. The yielding rate of the inserted small-sized silicon in the cast iron is about 85 % and reaches thereby the same range of lumpy ferrosilicon.

Title: Flattened collapsible vascular catheter
Inventor: PALESTRANT AUBREY M
IPC: A61M39/08
Filed: 1995-07-26
Granted: 2000-06-20
Abstract: An apparatus and method for establishing a collapsible infusion conduit in a blood vessel (46) includes a catheter (20) formed as a normally-flattened tube (44) of flexible, collapsible plastic. When placed in a blood vessel, the catheter collapses to a flattened configuration (fig. 3D) for lying along the wall of the blood vessel to avoid obstruction to blood flow. During infusion, infusion fluid expands the catheter to a generally oval flow path (fig. 3B).  The catheter may be initially placed in the blood vessel by pre-loading the catheter over a guide wire (50) and inserting the catheter and guide wire through an introducer sheath (78) into the blood vessel. Infusion fluid is thereafter applied to the trailing end (24, 28, 30) of the catheter to expand the catheter to facilitate withdrawal of the guide wire. Alternatively, the leading end (22) of the catheter may initially be sealed, and placement into the blood vessel is achieved through an introducer sheath (78) by inflating the catheter with pressurized fluid (72) to temporarily render the catheter rigid and generally oval. The seal at the leading end of the catheter is thereafter opened, either by inserting a guide wire (82) into the catheter to pierce the sealed end, or by increasing the inflation pressure to burst a weakened break line (74) formed at the leading end (22) of the catheter.
