Title: Hollow auger head assembly
Inventor: BURNS RAYMOND W
IPC: E21B10/44
Filed: 1996-03-22
Abstract: In a hollow earth auger head assembly a plurality of bit-holding pockets are provided, spaced circumferentially from one another around an open mouth of an auger head, and bits taken selectively from a multiplicity of types of cutting teeth, have a shank portion that seats in any and all of the pockets. A retaining pin extends chordally, off-set from a diameter, through holes in the pocket and into a retaining pin receiver in the bits. In those bits that are intended to rotate in the pocket, the retaining receiver takes the form of an annular channel. In those bits that are not supposed to rotate, the retaining pin extends through a linear passage in or along a flat on the bit shank. In certain embodiments of sockets a chordal plug or weldment defines a space with one flat side against which a tail of the shanks of certain bits designed not to rotate bear.

Title: Water powered pump drive unit
Inventor: ZIMMER-VORHAUS KLAUS
IPC: F01L23/00
Filed: 1994-10-07
Abstract: A reciprocating hydraulic ram pump drive unit (1) having a cylindrical body with a piston (7) sliding within the cylindrical body and forming two chambers (6, 17) each having respective inlet and outlet openings. A slide rod (9) passes through the piston (7) and has located at or adjacent its ends respective valves for choosing the respective outlet openings of the chambers (6. 17), whereby when one of the respective outlet openings is in the fully closed position, the other of the respective outlet openings is in the fully open position, and vice versa. Water flowing through one of the chambers (6, 17) assists to move the respective valve to the fully closed position and thereby converts the kinetic energy of the fiowing water into a pressure wave in that chamber, which forces the piston (7) away from the respective closed valve, thereby to move the drive rod (14) with it. After the pressure wave is dissipated, the water flowing in the other of the chambers (6, 17) due to the fully opened valve, urges this valve to the fully closed position, converting the kinetic energy of the flowing water in the other of the chambers (6, 17) into a pressure wave in the other of the chambers (6, 17) and thereby to move the piston (7) and the drive rod (14) in the opposite direction. Also disclosed is a bush assembly comprising a female (32) and a male (31) component each having a bore therethrough and a drive rod (14) of such dimension to pass through the bore of the male component (31) in the asssembled condition of the bush.

A capacitor (54, 56) couples each of the input signal conductor distal ends (48d, 48c) to an adjacent ground conductor (36, 38). The signal conductors (48b, 48c) and capacitors (54, 56) provide a selected impedance at a selected frequency. An output coplanar waveguide (28) includes, for each drain terminal (72) an output signal conductor (88) having an end (82a) in the connection region (32) that is electrically connected to the flip mounted FET chip (26). This waveguide (28) also has a length selected to provide desired impedance matching and may also have other means of impedance matching.

Patent CA-2188113-A1 (CA)
Inventor: BOUCHARD GILBERT
IPC: H04R1/02
Filed: 1996-10-17
Abstract: A  three-way  speaker  comprises  a  high frequency transducer, a mid-frequency transducer,  a low frequency transducer, and a hollow speaker cabinet defining   a   pyramidal   mid-frequency   transducer compartment and a low frequency transducer compartment isolated    from   the   mid-frequency   transducer compartment.  The high frequency transducer is mounted in a first hole of the cabinet opening in the low frequency transducer compartment,  the mid-frequency transducer is mounted in a second hole of the cabinet opening in the mid-frequency transducer compartment, and the low frequency transducer is mounted in a third hole of  the cabinet opening in the  low frequency transducer compartment.  Therefore, the isolated mid-frequency transducer compartment and low frequency transducer compartment also isolates the mid-frequency transducer from a displacement of air produced by the low  frequency  transducer  in  the  low frequency transducer  compartment.    This  prevents  the  mid-frequency transducer to produce distortion caused by this displacement of air.  Also, the pyramidal mid-frequency   transducer   compartment   improves   the performance of the mid-frequency transducer in the frequency range 150-1500 Hz.

Title: Patient bathing system
Inventor: PONSI LAWRENCE G
IPC: B65D75/58
Filed: 1997-03-17
Abstract: A resealable package having a label applied over an opening into the package. The label has a pressure-sensitive adhesive, and is repeatably peelable from the package body and reappliable thereto. Full peeling of the label from the body is inhibited by a portion of the label co-acting with a portion of the package body. In one form of the invention, the label has cuts on opposite sides with an uncut portion therebetween, and the inhibiting of peeling is due to puckering of the package and the label when the label is peeled back to the cuts. In a second form of the invention, the package includes tabs or fragments which adhere to the label, with the peeling being inhibited when un-cut portions of the tabs or fragments are reached.

Patent CA-2206477-A1 (CA)
Inventor: MONTGOMERY FREDERICK J
IPC: G01N33/497
Filed: 1997-05-29
Abstract: A system for correcting the concentration of NO2 detected by an electrochemical monitor in an apparatus for administering NO to a patient for therapeutic purposes. The system determines the effective monitoring time between the point in time that the sample of NO containing gas is removed by a sample conduit from the supply conduit to the patient and the point in time that the NO2 monitor actually analyzes the sample and determines the additional amount of NO2 that has been formed in the time-related reaction between NO and O2 in the sample conduit.    Using that additional NO2 calculated value, the reading of the NO2 monitor is corrected to subtract that additional calculated NO2 from the monitor read value to produce a corrected, more accurate reading to the user.
Patent CA-2207021-A1 (CA)
Inventor: ZUEV IGOR
IPC: B23K9/02
Filed: 1997-06-03
Abstract: A welding method that permits thick pieces of metal to be welded together over the entire face of their touching surfaces during a process of self organizing, single pass arc welding in the ambient air without any special proofing of the welding bath melt.  The higher quality and faster weld when welding considerably thick metals in a single pass is achieved by using an insulated stationary consumable electrode clamped between the parts to be welded together and by scientifically substantiated selection of the value of the electric power applied to the end face of the electrode.            The arc is distinguished by the fact that the value of its power is sustained at a level which keeps the pressure of the metal vapor Pme which arises due to vaporization of the electrode material in the welding zone higher than the air pressure Patm with a relation between them complying with the rule Pme ~ (1.1-2.0)Patm. This affords protection of the welding bath metal melt against air oxidation and interaction with other air elements such as N, H, H2O, etc.
