Abstract: A process for the production of a pollutant-free particulate carbon (i.e., a substantially ash-, sulfur- and nitrogen-free car-bon) from carbonaceous feedstocks (21). The basic process involves de-oxygenating one of the gas streams formed in a cyclic hy-dropynolysis (10) methane pyrolysis (34) process in order to improve conversion of the initial carbonaceous feedstock. De-oxy-genation is effected by catalytically converting carbon monoxide, carbon dioxide, and hydrogen contained in one of the, pyrolysis gas streams (44), preferably the latter, to a methanol co-product. There are thus produced two products whose use is known perse, viz.; a substantially pollutant-free particulate carbon black (53) and methanol (49). These products may be admixed in the form of a liquid slurry of carbon black in methanol.
Patent CA-2070707-C (CA)

IPC: F24F5/00
Filed: 1992-06-08
Granted: 2005-11-29
Abstract: A reversible vapour compression refrigeration plant serves as an air conditioner for cooling or as a heat pump for heating. A main stream of inlet air is divided into separate main and bypass streams of air and proportion of flow between the two streams is varied in an inverse ratio so that as flow through the bypass duct increases, flow through the main duct decreases and vice versa. When the plant is used for heating, the main stream is heated by a supply heat exchanger acting as a condenser and when the plant is used as an air conditioner, the supply heat exchanger acts as an evaporator. Also, as an additional alternative, as a desired air space temperature is approached, preferably heat rejected by a condenser in the heating mode, or heat gathered by the evaporator in the cooling mode, as gradually reduced by reducing refrigerant flow therethrough by modulating compressor suction. Full fresh air or full re-circulating air modes, or a combination of mixed and re-circulating air can be used.      Also, energy is saved in both the heating and cooling modes by locating an exhaust heat exchanger within exhaust flow discharged from the space to be heated or cooled.

Title: Method and an arrangement for distance measurement using the pulse transit time principle
Inventor: ELLE ANDRE
IPC: G01S15/52
Filed: 1993-06-01
Granted: 1996-12-10
Abstract: For the measurement of distance using the pulse transit time principle the received signal produced after each trans-mission of a pulse is stored as an echo profile and the effective echo is determined from the stored echo profile. In order to suppress recurrent interfering signals a stationary threshold profile adapted to the measurement environment is formed and employed for each evaluation of a stored echo profile. In order to take into account fluctuations in the properties of the received echo profile rapidly without necessitating a modification in the stationary threshold profile for this, from a stored echo profile a floating threshold profile is generated in the form of a monotonously descending curve. From the mutually corresponding values of the floating threshold profile and of the stationary threshold profile the respectively larger value is utilized for the formation of a resulting threshold profile, which is employed for each evaluation of stored echo profiles.

Title: Technique for administering personal telephone numbers
Inventor: FEIT SUSAN
IPC: H04Q3/47
Filed: 1993-11-16
Granted: 1997-03-18
Abstract: The drawbacks to administering a sequence of locations to which calls placed to a subscriber's personal telephone number may be routed for personal communication service are overcome by a) storing pre-defined mnemonic audible tags for association with telephone numbers prior to any interactions with the subscriber, b) offering the subscriber a choice of the pre-defined mnemonic audible tags by speaking them to him, c) receiving an indication of the mnemonic audibletag selected by the subscriber, d) receiving signals indicating a telephone number supplied by the subscriber; and e) storing the received telephone number information in association with the selected mnemonic audible tag. The mnemonic audible tagsare then used in place of their respective associated telephone numbers in administering the sequence of locations. A mnemonic audible tag is not simply anordering designation -- such as 1, 2, 3, ..., N; first number, second number, third number, ..., Nth number; A, B, C, ... --but instead is a meaningful word indicative of the actual location, person, or service, e.g., "office", "neighbor" or "AT&T voicemail", to which a call to the personal telephone number is to be completed.Advantageously, administering a sequence of locations is accomplished by simply manipulating friendly, meaningful, easy to understand terms rather than cumbersome, meaningless, telephone numbers or codes.

The notches, slits and pleats allow the front and rear portions of the article to freely bend upward into contact with the use's body and prevent lateral compression in the central portion of the article from being transmitted to the front and rear portions so as to undesirably increase the stiffness of the article in the longitudinal direction.
Patent CA-2112579-C (CA)
Inventor: DUNFORD DAVID VICTOR
IPC: B21D26/055
Filed: 1992-07-02
Granted: 2002-02-19
Abstract: The low peel strengths of diffusion bonded joints in aluminium alloy structures has been a bar to their use in superplastic forming. The invention overcomes this disadvantage by creating a workpiece intended for subsequent superplastic forming by dif-fusion bonding an assembly of alloy sheets (30-32) in bonding zones according to a predetermined pattern and providing reinfor-cing material (33) in the workpiece in the region of the diffusion bonded zones. The reinforcing material serves to prevent the ten-sile stresses exerted during subsequent superplastic forming from initiating peel fracture of the diffusion bonds. Instead, the tensile stresses act so as to bring about superplastic deformation in those regions of the workpiece between the diffusion bonded zones.
