Patent CA-2070146-A1 (CA)
Inventor: NYMAN BROR G
IPC: B03D1/22
Filed: 1992-06-01
Abstract: The present invention relates to a method for concentrating a certain mineral fraction attached to air bubbles from a slurry to the foam layer accumulated on the surface, so that the concentration takes place in three different mixing zones.  The apparatus of the invention is formed of a colon-like flotation arrangement and of flow guides, a flow attenuator and an agitator belonging thereto.  The flotation reactions are created in the bottom zone, wherefrom air bubbles and mineral particles carried by them are directed in a controlled fashion onto the surface of the apparatus. The flotation apparatus is so designed, that a strong agitation in the bottom zone can be used without causing harmful separation of the foam in the bottom part of the apparatus.

Inventor: WAGNER DAVID P
IPC: F16B41/00
Filed: 1992-07-13
Abstract: A fastener and a workpiece assembly comprises a fastener composed of a relatively strong, inflexible material having a shank. Wings are disposed on the shank, and the workpiece has portions thereof composed of a relatively flexible, resilient material. An aperture having a diameter is located through the portions. The wings define an outer diameter substantially greater than the diameter of the aperture. The wings are capable of swaging the apertures, thereby increasing the diameters thereof, to allow for passage of the wings. The relatively flexible, resilient material has sufficient elastic memory so that the diameter of the aperture will become smaller than the outer diameter defined by the wings after being swaged by the passage of the wings.

Title: Drilling tool for percussive and rotary drilling
Inventor: STJERNSTROEM KARL-AXEL
IPC: E21B7/20
Filed: 1991-01-17
Abstract: A drilling tool for percussive and rotary drilling in advance of a trailing casing tube (20) has a reamer (15) pivotally journalled on an eccentric shaft (12) rearwardly of a centric pilot bit (11). The reamer (15) has an eccentric portion (32) carrying axially directed hard metal button inserts (36-40) grouped within an acute angle (V) of a circle sector centered on the drilling axis (C). The inserts comprise primary inserts (36-38) with a radial reach defining the full diameter of the drilled hole and inner secondary inserts (39, 40) closer to the shaft (12). The reamer (15) is pivotable on the shaft (12) between a projected and a retracted position. When projected, the group of button inserts (36-40) ream up the hole from the diameter drilled by the pilot bit (11) to the full diameter of the hole enabling the casing tube (20) to advance. In the retracted position the drilling tool (10) can pass through the casing tube (20). A duality of inserts (36, 39) leading in the rotational direction act jointly to break the rock in said direction substantially tangentially relative to the shaft (12). The rock cuttings from the button inserts (36-40) are subjected to enhanced flushing action. Optionally such flushing action is further supported by a groove (52) on the rotationally leading flank of the reamer (15). A cutting edge (54) on the groove (52) is reinforced by stellite and improves drilling of claybound ground.

Abstract: CURABLE SILICONE PRESSURE SENSITIVE, ADHESIVE TAPE             Abstract A pressure sensitive adhesive tape comprising a tape substrate having at least a portion of one or more sides coated with a silicone pressure sensitive adhesive is constructed using an adhesive which  cures to a permanent adhesive.  The adhesive is covered on the outer side with a release film, preferably coated with a fluorosilicone release layer, to allow storage of the tape.  Preferably, the curable silicone pressure sensitive adhesive is cured upon exposure to moisture, the tape therefore being stored in the absence of moisture.

Title: Optical communication system
Inventor: WATANABE SHIGEKI
IPC: H04B10/572
Filed: 1992-09-11
Abstract: An optical communication system in which light is modulated in sending equipment according to a composed signal obtained by mixing a signal frequency-multiplexed at the microwave level in a coherent SCM optical communication system with an unmodulated signal out of the frequency band of the frequency-multiplexed signal. The resultant modulated light is optical-heterodyne-detected. A demodulating unit demodulates a frequency-multiplexed signal according to an electric signal delayed by a delay unit by the time equal to the time delay in an unmodulated component extracting unit.          Only the frequency components of a frequency-multiplexed signal and an unmodulated signal must be received in receiving equipment, without receiving the component in a broad frequency band from the frequency component to the main carrier component of the frequency-multiplexed signal.

Title: Production line equipment and related methods to manufacture large concrete panels, having integral end pilasters and artistic designs on both sides to be primarily used with others as a vehicle way sound barrier
Inventor: MYERS DOUGLAS W
IPC: B28B1/16
Filed: 1992-09-24
Abstract: Overall production line equipment and related methods of operations are utilized in producing many large concrete panels, in an initial horizontal position, during each day of many operational days, with these panels preferably being later installed vertically with other like panels to form a sound barrier alongside a vehicle way. Each concrete panel has its own integral pilasters at respective edges, in turn having respective tongue and groove edges; respective patterns and color accents on each side, with the pattern on the then top side being formed by using a rockable stamp subassembly, mounted on a cart; reinforcing throughout the panels, inclusive of the integral pilasters; lifting subassemblies; and anchoring subassemblies, adapted to be later mated with a receiving subassembly anchored in a concrete footing, located where the panel with other panels forms a sound barrier alongside vehicle ways. This production line equipment is extended longitudinally, utilizing tracks to support several electrically powered vehicles, respectively referred to as tarp roller cart, back rail cart, mesh cart, rebar cart, screed cart, color spreader cart, and stamp cart. Electrical power is distributed via a continuous electric T-track power supply system extending alongside the tracks. Each respective deck, supporting the bottom form assembly for a panel, is tiltable, upon being lifted off of a footing location, along the back rail side thereof, as the front rail side thereof is pivoted, while supported at another footing location. Each deck, along the longitudinal outside edges thereof, forms respective sections of the overall longitudinal tracks. Portions of the bottom form assembly are removably secured at a first pouring location on each deck, and then at a cleared strip location on each deck, except for inside back rails, which are completely removed from a deck before the tilting thereof, which is undertaken to position a concrete panel nearly upright, to be lifted clear of the deck and the form portions.
