Title: Three fluid method for non-mercury intrusion porosimetry
Inventor: GUPTA KRISHNA
IPC: G01N15/08
Filed: 1986-12-15
Granted: 1991-06-11
Abstract: ABSTRACT           A three-fluid method of non-mercury liquid intrusion porosimetry.  Thesample to be tested and a quantity of non-wetting intrusion liquid other than mercury are introduced into a sealable, pressurizable chamber, the sample being above the intrusion liquid.  The chamber is sealed and evacuated.  An intermediate pressurizing liquid, such an mercury, is introduced into the chamber and pressurized by a primary pressurization fluid, such as alcohol or oil, so as to force the intrusion liquid into the pores of the sample.  The volume of intermediate pressurization liquid introduced into the chamber is measured as the pressure is increased incrementally, to find the pore distribution of the sample.

Patent CA-1286720-C (CA)
Inventor: HIRSHBERG MOSHE
IPC: G01N27/36
Filed: 1987-08-25
Granted: 1991-07-23
Abstract: ABSTRACT           A test electrode for immersion in a sample solution having a selectively openable liquid junction is disclosed.  The electrode includes an electrode tube with a bottom opening.  The bottom opening is defined by a curved inside wall at the end of the electrode tube.  A connecting rod extends axially through the electrode tube.  A bulbous stopper is located at the end of the connecting rod outside of the bottom opening.  The connecting rod is attached to a cap located over the top of the electrode tube.      A biasing spring located inside the cap around the connecting rod between the top of the electrode tube and the base of the cap provides a selective force on the cap and connecting rod so the stopper normally abuts the electrode bottom opening.  A thin annular liquid junction forms before the area of contact between the stopper and the inside wall of the electrode.  Electrolyte inside the electrode can be flushed by depressing -the cap so the stopper is urged away from the electrode bottom opening so the liquid junction is opened.  The flow of flushed electrolyte over the stopper and the electrode end inside wall cleans the surfaces that form the liquid junction.  The connecting rod can be a hollow tube and the stopper can be supplied with an ion sensitive tip so the electrode of this invention can be a combination electrode, the outer electrode with the liquid junction being the reference electrode, and the connecting rod and stopper with an ion sensitive tip being the measuring electrode.

Granted: 1992-07-07
Abstract: ABSTRACT OF THE DISCLOSURE    An oxygen-rich gas product of at  least about 95% O2 purity is obtained from ambient air in a single-stage pressure swing adsorption operation carried out in four steps, comprised of: (a) selective adsorp-tion of nitrogen from the air feed at superatmospheric pressure, (b) fol-lowed, without intermediate purge or rinse, by pressure let down through countercurrent gas withdrawal to about atmospheric level, (c) desorption by evacuation of the adsorbent bed to subatmospheric pressure level of 1/20 (5%) or less than 1/20th of the pressure prevailing during the ad-sorption step; and (d) repressuring the evacuated bed with part of the oxygen-rich effluent obtained during the adsorption step.  Optionally, the operating cycle may include pressure equalization between two columns performed intermediate steps (a) and (b), whereby O2 recovery is in-creased.  Under the prescribed conditions the oxygen production capacity at high purity level (~95%) is substantially increased.

Title: Medium frequency mine communication system
Inventor: STOLARCZYK LARRY G
IPC: H04B5/00
Filed: 1988-05-16
Granted: 1992-02-18
Abstract: ABSTRACT OF THE INVENTION       A method for using an underground mine communication system to effect minewide communication and an intrinsically safe current limiter circuit for insuring that electrical equipment in the system will not cause incendiary conditions.  The underground mine communication system comprises a plurality of repeaters and medium frequency radios, including mobile, portable and personal-carried radios, coupled to electrical conductors and natural waveguides existing in the earth by tuned loop antennas. Messages transmitted by the radios are carried to the repeaters by the conductors or coal seam waves.  The repeaters amplify, replicate and retransmit the message at two different frequencies for transmission of the message to a surface base station and to other radios in the system.  A paging system, which has a separate set of repeaters, is also coupled to the network of electrical conductors and natural waveguides by tuned loop antennas.  The paging system alerts miners to contact the surface base station. Radios, pagers and repeaters in the system are equipped with the intrinsically safe current limiter circuit to preclude the development of incendiary conditions.  The current limiter circuit comprises a series arrangement of a current trip circuit, a redundant current trip circuit and a current limiting field effect transistor controlled by a feedback control amplifier.

Title: Machine for producing webs of fibrous material
Inventor: SCHIEL CHRISTIAN
IPC: D21F3/04
Filed: 1988-05-20
Granted: 1993-04-06
Abstract: ABSTRACT In a papermaking machine, the forming section wire is followed directly by a first longitudinal-nip press wherein an extended nip is formed between a press-roll  and a  flexible press element or tube which is adapted to be pressed against the press-roll by means of a press-shoe.  The press-roll is located under the upper roll so that the effective direction of the press-shoe is from top to bottom.  The web of fibrous material to be drained runs, jointly with an upper felt and a lower felt, along a straight, slightly upwardly inclined path, from the transfer from the forming section wire towards the nip in the first extended-nip press.   This first extended-nip press is followed by a second extended-nip press  in which the press-roll is arranged above the flexible press element, so that the effective direction of the press-shoe is from bottom to top.

Title: Data processing system
Inventor: WATSON PAUL
IPC: G06F15/177
Filed: 1988-07-14
Granted: 1992-06-16
Abstract: DATA PROCESSING SYSTEM Abstract of the Disclosure A data processing system is described in which the workload is divided into packets.  A plurality of processors access the packets and process them by rewriting them according to predetermined rules.  Packets can be of a number of different types, including XAPP and PAPP.  An XAPP packet contains a function and one or more arguments in evaluated form, so that the function can be immediately applied to the arguments.  A PAPP packet is similar except that its arguments may not be in evaluated form.  Processing of an active PAPP packet consists of activating other packets which evaluate the arguments of the PAPP packet, and converting the PAPP to a suspended XAPP packet, awaiting return information from those other packets.  The use of different packet types allows greater efficiency, by eliminating redundant actions in processing of the packets.

The device in one embodiment includes first and second flanges, which may be part of a yoke saddled over a support member, such as the shaft connected to the spare tire winch mechanism.  The flanges have holes through which an upper segment of a shaft is placed and held.  The lower segment of the shaft typically passes through the lug hole of the wheel, below which a lock housing is coupled to the shaft. A plurality of grooves are provided in the shaft to allow the lock housing to be placed at various positions therealong to accommodate various tire and wheel size combinations.  The upper segment of the shaft may include core and tab portions which engage a hole in one of the flanges when the upper segment of the shaft is rotated in the hole.  This may be accomplished using a tab having a chorded circle shape corresponding to a chorded circle profile of the hole.  A resilient member, such as a poly-foam gasket, may be provided along the top of the lock housing to reduce rattling and to provide a seal against dirt and water entering the lock housing.
