Patent CA-2074543-A1 (CA)
Title: Method of assembling a circuit-breaker pole, apparatus for carrying out this method and circuit-breaker pole for a medium-voltage or high-voltage circuit breaker
Inventor: KESSI ERICH
IPC: H01H33/56
Filed: 1992-07-23
Abstract: In the course of the assembly of a circuit-breaker pole, the individual parts of a housing are stacked loosely one on top of the other and fixedly positioned. This fixing can be accomplished by applying subatmospheric pressure or a partial vacuum within the housing and/or by means of a holding device.    Spaces open in the upward direction and located between a fitting and a support insulator as well as between a fitting and a quenching-chamber insulator are then filled with casting material. After this casting material has at least partially hardened, the circuit-breaker pole is turned upside down by rotating the holding device about a horizontal axis, whereupon spaces now open in the upward direction and located between a fitting and the quenching-chamber insulator as well as between a fitting and the support insulator are filled with casting material. This renders possible simple assembly, self-acting mutual alignment of contact pieces as well as a leak test prior to final assembly of the circuit-breaker pole.

IPC: C09K23/42
Filed: 1992-12-18
Abstract: A process for the preparation of large-particle, aqueous plastic dispersions by emulsion polymerization of free-radical polymerizable monomers is disclosed. The process is car-ried out in a system which controls the particle size and comprises an anionic emulsifier, an essentially non-branched, nonionic, water-soluble polymer auxiliary, which is added before the polymerization, and alkali metal and/or ammonium ions not bonded to emulsifier. The polymer auxiliary is an essentially non-branched polyethylene oxide having a AB block structure, where A is a hydrophobic radical comprising 15 to 70 C atoms and B is a non-branched hydrophilic radical comprising at least 50 ethylene oxide units. The polymer auxiliary can be prepared reproducibly in respect of its agglomerating effect.

Title: Thermostatically-controlled microwave cyclodestruction as a treatment for glaucoma
Inventor: FINGER PAUL T
IPC: A61F9/007
Filed: 1992-04-24
Abstract: A miniaturized microwave applicator comprises a thin-wall metal dielectric-filled waveguide (200) having a thermocouple (208) disposed in a groove (206) in the surface of the dielectric radiating aperture of the waveguide (200). When the aperture is placed in contact with a spot on the outer surface of the sclera overlying the ciliary body to cyclodestruct by heat generated by absorbed microwave energy radiated thereto during a given time, damage due to overheating of the scleral tissue is prevented by the thermocouple (208), which monitors the sclera surface temperature, being used to thermostatically control the microwave energy supplied to the waveguide in a manner that the scleral tissue temperature is maintained substantially constant at a value below that which would cause damage thereto. The desired operation is dependent on the fact that very little of the microwave energy is absorbed by the lower-water-content scleral tissue as it passes therethrough, but is highly absorbed by the underlying high -water-content ciliary-body tissue.

Title: Apparatus for convoluting labels around containers
Inventor: FIWEK WOLFGANG
IPC: B65C3/16
Filed: 1993-04-16
Abstract: ABSTRACT           Successive upright bottles, cans or similar containers for beverages are transported by a turntable along a circular path and are simultaneously rotated about their own axes.  Endless foraminous belts are provided to deliver and convolute discrete labels all the way around the external surfaces of successive containers.  The belts are driven to advance along an endless second path which has a portion adjacent and extending tangentially of a portion of the circular path.  The belts are propped from behind by a resilient rail which urges the labels against the respective containers and forms part of a suction chamber serving to attract the labels to the belts.  The speed and the positions of the belts relative to the circular path are changed if containers having external surfaces of a first diameter are followed by containers having external surfaces of a different second diameter. A first paster applies adhesive to the external surfaces of successive containers, and a second paster supplies adhesive to selected portions of partially convoluted labels on successive containers.  The pasters are surrounded by the first path.

Patent CA-2103254-A1 (CA)
Inventor: FARCHI DAVID
IPC: G01F1/36
Filed: 1993-03-11
Abstract: An apparatus and method for measuring the flow rates of each component of two-phase now consisting of a gas and a liquid or three-phase flow consisting of water, oil and gas, including a first volumetric flow meter stage, and second and third momentum flow meter stages coupled in a series flow path with the volumetric flow meter stage and in which a velocity ratio between the gas and the liquid in the series flow path is maintained to be one. A processor calculates flow rates of the components of flow by solving volumetric flow and momentum or energy equations defining flow through the first through third stages utilizing a volumetric flow output from the first stage and momentum flux outputs from said second and third stages, and an indicator displays flow of liquid and gas or oil, water and gas components of the flow. To measure three-phase flow, a water-cut meter is provided to determine the amount of water flow, which is then used by the processor to determine the flow of the rest of the liquid. The second and third momentum flow meter stages can be implemented by two separate momentum flow meters or by a single momentum flow meter, such as a venturi flow meter having a venturi nozzle including pressure taps for obtaining at least two differential pressure measurements. In the event that the density or the liquid component is known, a single momentum flow meter stage is sufficient.

IPC: B05B5/03
Filed: 1993-09-15
Abstract: A tribo-electric powder spray gun includes a diffuser for mixing powder with a conveying gas, a charging portion downstream of the diffuser, and a sprayhead at the outlet of the charging portion for dispensing the charged powder. The charging portion has an inner core removably positioned within a hollow outer cylinder with an annular gap formed between the outer cylinder and inner core providing a charging flowpath for the powder. The inner core and the outer cylinder have undulating or wavy charging surfaces made of an electrically insulating material, so that the annular gap provides a tortuous path for the powder, enhancing powder contact and the charge imparted to the powder. Grounding is provided by surface conduction of the electrically insulating contact material through a ground ring located outside the powder path at the inlet to the charging portion of gun where the greatest amount of charging occurs. By locating the ground ring outside the powder path, thsa ground ring is kept clean and the amount of charging surface is maximized. The inner core and the outer cylinder are longitudinally symmetrical to facili-tate re-assembly.
