IPC: B02C23/18
Filed: 1994-06-14
Abstract: A process for soil remediation is proposed where the soil is mixed with reagent and/or heated and subsequently pulverized and aerated by a centrifugal pulverizing structure, by this the toxic ingredients in the soil are oxidated or reduced to stable non-toxic substances, the vapours emitted from the process are treated by filtering / incinerators or collected by condensation.
Patent CA-2130351-A1 (CA)
Title: Power controller device
Inventor: DOSANI NAZIR
IPC: G05F1/66
Filed: 1993-07-12
Abstract: A power controller device (10) is provided which controls the power output to a resistive load, such as a water heater (2) or baseboard heater. The device is programmed to output predetermined power levels or to energize the load to predetermined temperatures during predetermined time intervals, thus taking advantage of times during the day when power usage is low, and minimizing usage of power during times when demand is high. A voltage detection circuit monitors the supply voltage, and can increase power or temperature to the load during times of over-voltage or can disable the load during brownout or blackout conditions. Power is reduced through a convention means such as "cycle-stealing", and power can be output to the load in fractions of the maximum output power level. When the load is first activated, power is supplied in gradually increasing levels, to avoid a sudden power surge. The power controller device (10) may control a stepper motor actuating a by-pass valve, where a water heater is provided with a heater exchanger, or otherwise actuating a mixing valve.

Patent CA-2131673-A1 (CA)
Inventor: ARNOLD TODD W
IPC: G02B26/10
Filed: 1994-09-08
Abstract: An improved access control apparatus, method, and system are disclosed to enhance the security of information in cards of the type having data storage and functions which are not accessible without verification of the identity and the authority of a person requesting access. The card need not include identification information for others that may require access to information in a person's card. Several authorization profiles are provided in a card, but there is no need that a profile be identified to any one person in order that they each may perform required tasks using or adding information in another person's card. The identification card of a supervisor or doctor who requires access to another person's card contains secret information Xsup identifying the supervisor or doctor as having the authority of supervisor or physician and an encryption key. The secret authorization information is encrypted and transmitted through the reader to the other person's card where it is decrypted and compared with the X'sup secret value stored in the other person's card. If they agree, the supervisor is permitted to perform functions authorized to be performed by supervisors in accordance with the profile for supervisors in the other person's card. Each supervisor is identified by a supervisor's own card using a password, PIN, or biometrics that may be changed as often as desired without recalling the cards of others for update. The authorization information is not exposed outside of a secure environment.      Therefore, unlike PINS which are exposed during entry, it need not be changed or updated during the life of the card.

Title: Thermoplastic syntactic foam pipe insulation
Inventor: MURRAY THOMAS J
IPC: B29C70/66
Filed: 1993-03-29
Abstract: Flexible syntactic foam insulation, and methods for making it, are disclosed. A low melt index thermoplastic resin is fluidified to produce a melt stream, and microspheres are metered into the melt stream under low shear conditions. The method allows for faster production of syntactic foams and for the production of higher quality foams because breakage of the microspheres is substantially reduced.

Title: Method for the determination of the amount of a ligand in a biological fluid and kit for carrying out such a method
Inventor: BERGMANN ANDREAS
IPC: G01N33/577
Filed: 1993-04-22
Abstract: Method for the determination of the amount of a ligand (L), in particular of a free ligand in the presence of physiological binding proteins, in a sample of a biological fluid, in which the biological fluid containing the ligand (L) to be determined is incubated in the presence of a dissolved ligand derivative (L-IgG), which can be converted into an insoluble form, in the liquid phase with less than the stoichiometric amount of a labelled specific binder (Ak*) which binds both the ligand (L) to be determined and the ligand derivative (L-IgG) so that the ligand (L) to be determined and the ligand derivative (L-IgG) compete for the labelled specific binder (Ak*), and in which the ligand derivative (L-IgG) is converted into an insoluble form and, after separation of the insoluble components of the assay system from those components of the assay system which remain in the liquid phase, the amount of the ligand (L) to be determined in the biological fluid is isolated from the amount of the labelled specific binder (Ak*) bound to the ligand derivative (L-IgG), wherein, according to the invention, a conjugate of the ligand with a substrate protein is used as the ligand derivative (L-IgG) and the reaction is carried out in a test tube whose walls are coated with a protein material (anti-IgG) which specifically binds the substrate protein part of the ligand derivative (L-IgG) without affecting the bond between the ligand part of the conjugate and the specific binder (Ak*).

Title: Apparatus for deflating tires of moving vehicles
Inventor: GREVES KENNETH J
IPC: B26F1/24
Filed: 1994-09-28
Abstract: A tire-puncturing apparatus is disclosed which can be placed on a road surface in front of a moving vehicle such as an automobile. The apparatus has a collapsible outer cover which makes it safe to handle the apparatus before its use, yet being collapsible, does not impede the operation of the apparatus in puncturing the tires of the target moving vehicle. The apparatus also has a flexible interior cover made of rip-resistant material. A special three-piece spike is used to first penetrate the tire's surface and then embed a hollow quill in the tread of the tire such that the tire will deflate at a controlled rate, rather than causing a blowout and subsequent loss of control of the vehicle. The tire-puncturing apparatus is designed to be easily carried in the trunk of a police vehicle, and has an optional mating connector such that two or more of the tire-puncturing devices can be rigidly connected together to cover a larger portion of the road surface.
