Abstract: Dry cementitious compositions and packages and methods for their application.  The dry compositions do not have to be mixed with water but instead are poured, sprayed or troweled onto a substrate which contains water in an amount in excess of that necessary for the hydration of the cementitious materials. These compositions can be applied by layering, dropping through a conduit, or preferably, merely dropped into the water. Also, a method of mixing materials is disclosed.  A fluid medium, such as an aqueous fluid or a gas, is continuously introduced into a mixing column for a time sufficient to allow the fluid to at least substantially fill the column. A predetermined amount of at least one primary material is introduced into the upper end of the mixing column.  The primary material is permitted to descend through the fluid medium at a predetermined rate.  Secondary materials are introduced into the mixing column through at least one end or through at least one position along the side of the mixing column at an angle and velocity sufficient to cause the secondary materials to intimately contact the primary material along its path of descent through the fluid medium so that the primary and secondary materials are continuously mingled as they descend through the fluid medium until they reach the lower end of the mixing column. Another aspect of the invention relates to the mixed materials which are recovered from the lower end of the mixing column.

Title: Tubular sleeve handling and cut-off system
Inventor: SICKA RICHARD W
IPC: B26D3/00
Filed: 1989-04-25
Granted: 1993-03-16
Abstract: ABSTRACT OF THE DISCLOSURE         A system for handling a flexible thin wall tubular extrudate of an elastomeric material of the type used as a body ply element for the manufacture of tires, and for cutting-off a predetermined length sleeve of the extrudate and delivering the sleeve to a discharge station.  A pair of grippers is movably mounted on carriage assemblies which move the grippers horizontally and transversely with respect to the axis of the extrudate.   The leading gripper provides tension to the extrudate and pulls it along a production axis.  The trailing gripper engages the extrudate and moves in unison with the extrudate and the leading gripper along the production axis. The grippers completely circumferentially envelop the length of sleeve to be cut from the extrudate and retain the shape of the extrudate by applying a vacuum thereto.  A cutting mechanism having a fixed motor driven blade and a pair of similar pivotally mounted blades moves vertically down into contact with the extrudate between the pair of grippers.  The rotating blades are rotated through at least 120° arc to achieve a 360° cut on the extrudate as it is being moved under tension longitudinally by the grippers.   After completion of the actual cutting operation the leading gripper transfers the severed sleeve to a discharge station and returns to a home position and now becomes the trailing gripper.   The previous trailing gripper becomes the leading gripper and continues to advance the extrudate along the production axis and apply tension thereto for the next cutting operation.

Abstract: ABSTRACT         An adjustable connector for optically connecting one optical fibre to another fibre or a light source is disclosed.  In one embodiment a base plate mounting the fibre is connected to another base plate with a resilient member between the base plates.  The fibre terminates at a beam expanding or imaging lens.  Sets of alternating first and second screws axially extend from one base plate to the other such that when a test signal is transmitted to the fibre the first screws can be adjusted to coarsely tilt one base plate relative to the other until approximately the desired signal strength is achieved.  The second screws are then rotated to finely adjust the base plates to achieve the desired signal strength.  In other embodiments adjusting screws extend radially with respect to a cylindrical housing holding the fibre so as to adjust the relative position thereof.          Adjustment can also be achieved using a temporary jig which can be removed and reused.  With the invention insertion and tilt losses at the connector are minimized.

Abstract: TERMINATING CIRCUIT IN A BATTERY FEED CIRCUIT      OF AN ELECTRONIC EXCHANGE SYSTEM     ABSTRACT OF THE DISCLOSURE      Disclosed is a terminating circuit in a battery feed circuit of an electronic exchange system.  The battery feed circuit comprises two transconductance amplifiers connected by a coupling capacitor, for supplying a direct current through a ring terminal and a tip terminal to a load.  Each of the transconductance amplifiers comprises an operational amplifier (21, 22); a resistor (RF) connected between the output end of the operational amplifier and the tip terminal or the ring terminal, and an impedance unit connected between the inverting input terminal of the operational amplifier and the output end.  The impedance unit has an impedance determined in such a way that the required terminating impedance of the battery feed circuit when viewed from the tip terminal and the ring terminal is formed only by the internal elements including the impedance means and the resistor, whereby an external larger-size capacitance capacitor for matching becomes unnecessary.

Abstract: The present invention comprises a lawn-mower having a grass-collector (6). For attachment of the collector (6) on the lawn-mower the casing (1) of the mower is provided with a curved superstructure (7). The front edge (13) of the grass-collector (6) like the superstructure (7) has the same curvature as the outer turning radius of the knife (5). In mowing, the mown grass is sucked towards the casing (1) and thrown back through a passage (11) directly into the collector (6). Due to the curvature of the superstructure (7) and the collector (6), respectively, it is possible to connect the grass-collector (6) as far as to the knife system, which eliminates any transportation distance for the mown grass which often is both wet and sticky.
