Patent CA-2287489-C (CA)
Inventor: KNEPPLE RONNY
IPC: B01L3/14
Filed: 1999-02-12
Granted: 2009-05-05
Abstract: The invention refers to a method of providing sample containers with an automatically readable identification for an analysis device, in which the sample container may be heated to an operating temperature. It is the object of the invention to improve the identification of sample containers in a manner that the sample contained in the sample container is not contaminated by the constituents of the identification agent during analysis. The object of the invention is solved in that during the manufacturing process of the sample container, the identification is applied during the final cooling phase of the ready sample container in a temperature interval between a maximum temperature during the sample container manufacture and the operating temperature. By the method according to the invention, volatile constituents of the identification agent are advantageous evaporated during the manufacturing process, so that when using the sample container during operating temperature of the analysis device, the sample to be analyzed is no longer contaminated by the exhaling constituents of the identification agent.

Title: Aqueous dispersion of an oil soluble demulsifier for breaking crude oil emulsions
Inventor: SELVARAJAN RADHAKRISHNAN
IPC: C09K/
Filed: 1999-08-25
Granted: 2008-10-21
Abstract: Demulsification of a water-in-oil, especially a water-in-crude oil, emulsion is effected by contacting it with an aqueous composition having at least one oil--soluble demulsifier and at least one water-soluble surfactant. These aqueous formulations are advantageous over conventional organic formulations of demulsifiers, as the need for toxic and/or flammable/combustible organic solvents is eliminated.

Title: Electromagnetic relay
Inventor: KERN JOSEF
IPC: H01H50/24
Filed: 1998-08-28
Granted: 2007-05-29
Abstract: The inventive relay has a base body in the form of a coil body (1), said base body supporting a core (16), a yoke (20), an armature (22) and a contact spring (23) which is connected to the armature. Fixed contact supports (3, 4) and a contact spring connection pin (5) which consist of semi-finished wire with a preferably rectangular or square cross-section are embedded in a flange (12) of the coil body (1). The inventive electromagnetic relay is therefore very simple to produce. There is no wasted material, no punching tools are needed for the contact connection parts and since no particles of plastic are abraded by insertion, there is no risk of this impairing the quality of the relay.

Title: Electrically operated railroad switch machine
Inventor: HOYER RAY
IPC: B61L5/10
Filed: 2000-06-02
Granted: 2009-09-15
Abstract: A switch machine for moving railroad switch points. The switch machine includes a switch stand adapted to be connected to the railroad switch points. The switch stand includes a rotatable hub which is selectively rotatable to throw the switch points. A rotary actuator includes a rotatable pinion that is coupled to the hub of the switch stand. A hydraulic pump and a valve are in fluid communication with the rotary actuator and selectively control the direction of rotation of the pinion. A first proximity sensor and a second proximity sensor are provided to sense the position of the pinion and hub. When the pinion and hub are rotated to a first position to move the switch points to a first switch point position, the first sensor will deactivate the hydraulic pump. When the pinion and hub rotate the switch points to a second switch point position, the second proximity sensor will deactivate the hydraulic pump.

Abstract: A pipe freezing apparatus comprises a multi-cavity adapter (20) and an evaporator (36) adapted to be fitted therein. The present invention uses a multi-cavity adapter having from two to eight cavities (42-48) to fit standard plumbing pipes in copper, steel and plastic, metric and US standard. The refrigeration evaporator fits into a cylindrical bore (36) in the core of the radial multi-cavity array. The cavities are arrayed around the circumference of the bore. The adapter body that forms the array is of aluminum or the like. The coolant lines (132, 134) are elbowed at 90 degrees to the evaporator's longitudinal axis to facilitate attachment to the pipe in small or tight spaces and from the side of the pipe. The adapter body freely swivels around the evaporator thus reducing wear on the refrigeration tubes as the adapters are mounted on the section of pipe to be frozen. Thus any of the cavities can be lined up with the pipe. A set of special retainer mechanisms (90, 92) is used to tightly secure the adapter bodies to the section of pipe to be frozen, thus providing for close thermal contact.

Abstract: A method and apparatus for reducing operating and maintenance costs and emissions in a chemical and/or Fluid Injection System. A first step involves providing an electronic flow controller system. The electronic flow controller system consists of three main components: 1. Electronic monitoring and control system making up control box 2. Metering chamber and 4 solenoid actuated valves making up valve assembly 3. Power supply The invention sends a series of pulses from the control box to the valve assembly by means of an electrical cable. The signals cause the valves to open and close first filling the metering chamber with fluid and then discharging fluid into desired injection points this then constitutes one cycle. The number of cycles per day would determine the amount of fluid that would be discharged into the injection point. The fluid for the system would be provided by a tank or vessel mounted on a stand to provide a gravity feed to valve assembly. Power for the system could be supplied by A.C. where available or D.C. by means of batteries and solar power. Operation of the chemical and/or Fluid Injection System is in response to external inputs such as temperature or flow monitors.
