Title: Digital transmission system for transmitting a plurality of binary signals on a conductor pair
IPC: H04L25/03
Filed: 1990-01-20
Abstract: The invention relates to a digital transmission system for the simultaneous transmission of a plurality of binary digital signals via separate conductor pairs. In addition to a threshold detector (SD) known per se, a noise value predictor (1) is used. Its sampling values are derived from the differential signal (ri) obtained from the Nyquist-equalised signal (ki-1) and the detected signal (vi). This considerably increases immunity to cross-talk interference.

Title: Controller for underwater pump
IPC: F04B49/025
Filed: 1990-03-06
Abstract: A controller for an underwater pump which operates 
to start and stop the pump in response to a water level 
detected by a water level sensor is disclosed. The control­
ler (10) is constituted as a separate component which 
comprises a watertight case (11), a first connector (13) 
provided at a first predetermined position of the case for 
installation on a power connector (12) provided at a pump 
casing (51), a second connector (14) provided at a second 
predetermined position on the case, on which an external 
power connector (15) is to be installed, electronic parts 
and units (18, 19, 20) constituting a control circuit 
installed in the case for starting and stopping the pump 
based on signals output from the water level detection 
sensor (S₁, S₂, S₃), and a cable (22) watertightly derived 
from the case externally for electrically connecting the 
control circuit and the water level sensor.  
     The pump may be operated in an automatic operation 
mode. However, by removing the controller from the pump 
casing and the external power connector and by directly 
connecting the external power connector to the power 
connector of the pump, the pump may be converted to a 
non-automatic operation mode.

Title: Locking ring for oil well tool
IPC: E21B33/043
Filed: 1990-04-10
Abstract: A connection assembly secures a running tool into a 
tubular casing hanger. The connection assembly includes a 
frusto-conical threaded section (35) on a running tool and 
a nose section (41) of cylindrical shape located below the 
threaded section. The casing hanger has a bore (13) with at 
least one circumferential recess (15,23). A collet ring (47) 
having internal threads (49) is initially carried on the 
nose section. The collet ring lands in the recess when the 
running tool is moved into the casing hanger. Continued mo­
vement causes the collet ring to deflect outward. The collet 
ring has threads on its inner diameter that slide on the 
threads of the running tool to latch the members together. 
Slots (65,67)in the collet ring enable the outward deflec­
tion to occur. A pin (31) engages the collet ring to enable 
rotation of the running tool relative to the collet ring to 
unscrew the members from each other.

Title: Directional drilling method
IPC: E21B33/138
Filed: 1992-01-06
Abstract: The direction of drilling of a well bore is 
changed by forming a cement plug in the well bore at a 
location therein where the direction of drilling is to be 
changed and drilling a pilot hole in the plug. The cement 
plug is formed using a particular slurry comprising a 
mixture of water and hydraulic cement in a weight ratio of 
from 0.5:1 to 5.0:1; the particle size of said hydraulic 
cement is no greater than 30 microns; and the Blaine 
Fineness of said hydraulic cement is no less than 6,000 
cm²/g. The use of such finely divided hydraulic cement 
significantly reduces the waiting time required for the 
slurry to develop compressive strength.

Title: Improved rapeseed exhibiting an enhanced oleic acid content.
Inventor: WONG RAYMOND S C
IPC: A01H5/04
Filed: 1988-12-29
Abstract: Improved rape plants, seeds capable of forming the same, and a novel improved vegetable oil derived from the rapeseeds are provided. Such plants have the ability to yield a vegetable oil of increased heat stability in combination with other desirable traits. The increased stability of the vegetable oil is attributable to the presence of an unusually high oleic acid content in the rapeseeds which has been lacking in the available rape plants of the prior art. It has been found that the novel rape plants of the present invention reliably can be formed by mutagenesis followed by selection as described. The vegetable oil produced by the improved rape plants of the present invention is particularly well suited for use as a frying oil wherein the increased stability at elevated temperatures is of prime importance. In a preferred embodiment wherein the vegetable oil is used as a frying oil, the alpha-linolenic acid content concomitantly is reduced which additionally imparts an increased oxidative stability.
