Patent CA-2219165-A1 (CA)
Title: Pressure-augmented kiss seal
Inventor: KOCH WILLIAM J
IPC: F16J3/04
Filed: 1997-10-22
Abstract: A kiss seal (42) of C-shaped cross section is provided. The kiss seal (42) includes a first leg (54), a second leg (56), and an arcuate middle portion (46) extending therebetween. The first leg (54) includes a contact surface (24') positioned adjacent a separable flange (28). The second leg (56) is attached to an opposed attachment flange (18) using a face plate (20') and a number of screws (22).  The second leg (56) is generally located directly beneath the first leg (54).  During sealing use, the arcuate middle portion (46) extends greater-than-180 degrees and is located outboard of one or both flange outboard edges (31). This provides a resultant force vector (58) that acts to enhance sealing. The greater the pressure (P) on the arcuate middle portion (46), the greater the force vector components available to promote sealing.

Title: Wiper cushion
Inventor: KOHLRUSS GREGOR
IPC: A47L1/08
Filed: 1996-05-23
Abstract: The invention concerns a pressure-deformable wiper cushion for wiping misted and/or dirty in particular flat surfaces such as the insides of vehicle windows. The cushion has a bag-shaped cleaning cover (10) the outside of which during wiping comes into contact with the surface being cleaned; and a cushion filling (6) enclosed by and filling out the cleaning cover on the inside (7). As a way of significantly improving the wiping effect even on dry surfaces, while maintaining ease of use, it is proposed that a container (5) should take the place of part of the cushion filling (6) in the cushion interior and should comprise a reservoir section (9) and a closable neck (4), and that a mechanically operated spray head (3) should be incorporated in the neck and fitted with a spray nozzle (8) outside the cover.

Title: Laser identification system
Inventor: GERBER PETER
IPC: F41A33/02
Filed: 1998-01-21
Abstract: A soldier carries a weapon on which a laser device (1) is mounted, which is used for illuminating a harness device (6) on the body of another soldier.  This harness device is provided with sensors (61, 62, 63, ...), which perform detection tasks for several applications in connection with arbitrary simulation scenarios in the course of exercises and battles. The laser device (1) has a laser target illumination element which is designed for transmitting tightly bundled laser beams (11), as well as chopper means for transmitting laser beams which are not only coded, but also chopped at a predeterminable frequency. The sensors contain tuning means for obtaining an alternating electrical signal from the received chopped laser beams, which is supplied to a pre-amplifier connected upstream of a discriminator. A very sensitive laser identification system results due to the fact that the electrical signal obtained in this manner can be very strongly amplified.

Title: Apparatus and method for combined acoustic and seismoelectric logging measurements
Inventor: CHENG ARTHUR CHUEN HON
IPC: G01V11/00
Filed: 1998-04-21
Abstract: A method for estimating porosity of an earth formation from measurements of acoustic energy traversing the earth formation and from measurements of seismoelectric voltages generated in the formation in response to the acoustic energy. The method includes the steps of measuring the acoustic energy traversing the earth formation and measuring said seismoelectric voltages generated in response to the acoustic energy traversing the formation. A seismoelectric signal is synthesized from the measurements of the acoustic energy using an initial value of the porosity. A difference is determined between the synthesized seismoelectric voltages and the measured seismoelectric voltages. The initial value of porosity is adjusted, and the steps of synthesizing the seismoelectric voltages from the acoustic signal, determining the difference, and adjusting the value of porosity are repeated until the difference drops below a predetermined threshold or the difference reaches a minimum value. The adjusted value of porosity which results in the difference being at the minimum is taken as the formation porosity. A particular embodiment includes estimating conductivity of fluid in the pore spaces of the formation by calculating the synthetic seismoelectric voltages using an initial value of conductivity; determining a difference between the synthetic seismoelectric voltages and the measured seismoelectric voltages; and adjusting the initial value of conductivity, and repeating the steps of calculating the synthetic seismoelectric voltages, determining the difference and adjusting the value of conductivity until the difference reaches a minimum.

Title: Offset sulky
Inventor: MILLINGTON HOWARD G
IPC: B62C3/00
Filed: 1998-08-14
Abstract: An improved horse drawn sulky for harress racing, which is inexpensive to manufacture, and which compensates for the lateral forces caused by banking of the track and turning. The frame of the sulky is formed so that the wheel on the outside of the track is forwardly offset relative to the wheel on the inside of the track.  In addition, the frame affords each wheel a camber which more nearly aligns the wheels with the surface of the track.  The offset design is simple to manufacture, and in experimental trials, has improved traction on a banked track and improved tracking in turns.

Title: Method of assaying downhole occurrences and conditions
Inventor: SMITH LEE MORGAN
IPC: E21B47/00
Filed: 1997-03-21
Abstract: A method of assaying work of a bit (10) of a given size and design comprises the steps of drilling a hole with the bit (10) from an initial point (I) to a terminal point (T) and recording the distance between the initial and terminal points. Electrical incremental actual force signals (18) are generated, each corresponding to a force of the bit (10) over a respective increment of the distance between the initial and terminal points. Electrical incremental distance signals (14) are also generated, each corresponding to the length of the increment for a respective one of the incremental actual force signals (18). The incremental actual force signals and incremental distance signals are processed to produce a value corresponding to the total work done by the bit in drilling from the initial point to the terminal point. Using such a work assay, a number of other downhole occurrences and/or conditions can be assayed.
