Patent CA-2185734-A1 (CA)
Inventor: THOMPSON WAYNE
IPC: A01M7/00
Filed: 1996-09-17
Abstract: A system is used for applying fertilizer to a field  (12). A nutrient  requirement map is first obtained  for  the  field  (12)  indicating  nutrient requirements for a plurality of locations in the field (12).  A first blend of fertilizer is calculated based on the nutrient requirements. Fertilizer components are blended to form the first blend.  The first blend is loaded into a first bin of an applicator. The first blend is then applied with the applicator at a first application rate, wherein the first application rate varies as the applicator travels across the field (12) based on nutrient requirements corresponding to the location over which the applicator is then traveling.

IPC: E21B7/08
Filed: 1996-09-27
Abstract: A retrieval tool for whipstocks is disclosed. A latch is retractable into the tool upon application of hydraulic pressure. A locking pin securely fastens the whipstock and retrieving tool together. The hydraulic pressure acts a cleaning force on the top of the whipstock and the retrieving slot to facilitate engagement. The offset stabilizer, when oriented opposite the lug on the retrieving tool, creates a force in the direction of the lug, whereby latching the retrieving tool will start. A joint of drillpipe or heavyweight drillpipe is run above the eccentric stabilizer. An offset stabilizer is provided to ensure proper initial orientation and avoid sticking the tool. The latch can firmly grip lugs within a slot in the whipstock. A overshot design is also disclosed using a similar hydraulically actuated latchassembly where the latch grabs the whipstock without having to use an opening therein, if for any reason the opening has been fouled with debris or damaged due to milling. Generally, release from the whipstock cannot occur unless hydraulic pressure is reapplied to release the latch and locking pin, thus allowing them to retract toward the body of the retrieval tool.

Title: Deep well submersible pump with upthrust protection
Inventor: SMITH ROY ALLISON
IPC: F04B47/06
Filed: 1996-12-06
Abstract: A deep well submersible pump is disclosed. It includes a plurality of pump stage assemblies, each of which comprises a diffuser stage, an impeller and a stage plate. The pump diffuser stage and impeller designs disclosed herein incorporate a means of continuously counteracting and absorbing upward thrust forces imposed on a pump when intermittently or continuously operated at low discharge pressures and high flow rates outside the normal design or operating range of the pump. Wear on the impellers when the pump is operating in upthrust conditions is thus reduced.

Patent CA-2198116-A1 (CA)
Inventor: POLK MATTHEW S JR
IPC: H04R1/28
Filed: 1995-08-09
Abstract: A single-vented bandpass woofer loudspeaker system design and method for enabling operation in smaller enclosure volumes with only moderate loss of efficiency. The bandpass system has an enclosure (11) with a partition (14) dividing it into a first sealed chamber (12) and a second chamber (13) having a passive radiating port (18) communicating with air outside the enclosure. A  driver (16, 17) is mounted in the partition. Novel, empirically determined tuning ratios which depend upon system variables are defined. By adjusting the system variables to keep the tuning ratios within empirically determined values, a good relationship between flat response, bandwith and efficiency is achieved. Unexpectedly, using a higher than normal moving mass of the driver leads to an acceptable system with a very small enclosure volume.

Patent CA-2200047-A1 (CA)
Title: Method and apparatus for weight controlled portioning of articles having non-uniform weight
Inventor: KVISGAARD THORKILD
IPC: G01G19/38
Filed: 1995-09-15
Abstract: A batching of currently supplied articles with non-uniform weights into portions of a uniform target weight is effected by passing the articles through a weighing station (6, 8) to a distribution system (12), in which the articles (4) are selectively allocated to a plurality of receiver bins (14). It is known to improve the capacity of such a system by way of probability calculations based on the normal distribution of the articles in the supply flow, but according to the invention it is still better to base such calculations on a regularly updated recorded histogram (28) of the weight distribution of a relatively high number of newly weighed articles. Thereby the target calculations will rely on factual rather than just expected conditions, and a very important result is that it is possible to effect relevant batching even when the article weights in the supply flow are not normally distributed.

Patent CA-2204724-A1 (CA)
Inventor: RAWLINGS JOHN P
IPC: F24J3/08
Filed: 1995-10-20
Abstract: L'invention concerne un système de thermopompe améliorée puisant la chaleur dans le sol, selon lequel l'installation de canalisations souterraines comprend des échangeurs de chaleur modulaires. Chaque échangeur de chaleur modulaire (36, 38, 40) comprend une pluralité de conduits secondaires parallèles (52). Ces conduits secondaires (52) sont reliés aux conduits primaires (42) par des collecteurs d'entrée et de sortie à plusieurs étages (48, 54). Chaque collecteur comprend un élément d'extrémité ou en "T" à trois voies (80) et au moins un, et peut-être plusieurs, éléments de raccordement à quatre voies (60, 90). Chacun des éléments d'extrémité (80) comporte une entrée (82) et au moins une, et de préférence, deux sorties (84, 86). Chaque élément de raccordement (60, 90) présente une entrée (62, 96) et au moins deux, de préférence, trois sorties (64, 66, 68, 98, 100, 102). Les entrées et les sorties des éléments d'extrémité et des éléments de raccordement sont configurées pour se raccorder, de manière interchangeable, en un mode mâle-femelle. Des organes coudés (70) permettent de raccorder les extrémités des conduits secondaires aux entrées et aux sorties des éléments d'extrémité et des éléments de raccordement. Ainsi, deux types seulement de composants sont nécessaires pour construire les échangeurs de chaleur comportant tout nombre de conduits secondaires. Pour augmenter le nombre de ces derniers, il est possible d'ajouter d'autres éléments de raccordement. Cela supprime la nécessité de construire un collecteur différent pour chaque taille d'échangeur de chaleur.

Title: Method in winding
Inventor: RAUDASKOSKI VESA
IPC: B65H18/20
Filed: 1996-10-29
Abstract: The invention concerns a method in winding, wherein a number of separate rolls (13a, 13b, 13c, 13d, 13e, 13f) are formed side by side around separate roll spools (15a, 15b, 15c, 15d, 15e, 15f) placed one after the other while supported by support members (11, 12). In order to reduce the friction coefficient of the roll spools (15a, 15b, 15c, 15d, 15e, 15f), before, or at the same time as, the roll spools are placed in the winding position, the ends of the roll spools are treated with an agent that reduces the friction coefficient, or pieces of a material that has a low friction coefficient are placed at the ends of the roll spools, and/or the axial thrust force between the roll spools is lowered by passing a pressurized medium through the spool locks.

Title: System and method for enhanced intelligibility of voice messages
Inventor: ROCHKIND MARK M
IPC: G10L21/04
Filed: 1997-10-21
Abstract: A  system and method  is  provided  for  playing  back  a recorded  voice  message,   and,   in  particular,   for automatically playing back a spoken numeric portion of the message at a rate that is slower than the rate for playing back the remaining portion of the recorded voice message.  A voice messaging system receives and analyzes the voice message.   Specifically,  the messaging system determines  whether  the  voice  message  includes  spoken numeric information and,  if so, determines the relative position of the spoken numeric information within the message.   The  computer  system stores  both  the  voice message  and  the  positional  information  in  a  storage device.   Upon playback of the message,  the messaging system retrieves the stored voice message and positional information  from  the  storage  device.    As  the  voice message is played back,  the messaging system processes the  positional  information.   When  the  positional information  indicates  that  a particular portion  of a voice message includes spoken numeric information, that particular portion is played back at a decreased speed.
