Title: Tubular rock bolt
Inventor: BROOKS ROBERT B
IPC: E21D21/00
Filed: 1987-10-20
Granted: 1992-05-19
Abstract: ABSTRACT     A high tenacity rock bolt system utilizes a cold drawn steel tubular rock bolt construction possessing excellent load bearing and installation characteristics.  The bolts are installed in bores drilled in the back, wall or rock face to reinforce the strata against local disturbances, and to maintain the strata in an effectively compressed condition. The subject tubular rock bolt may incorporate a visual Ground Movement Indicator (GMI) freely suspended as an unloaded rod element within the rock bore, extending through and projecting outside of the rock bolt, to afford visual indication of any axial displacement or elongation of the rock bolt consequent upon loss of anchorage and for settlement of the strata, or movement of the strata, inter alia to cause significant extension in the rock bolt.  The hollow construction of the rock bolt greatly assists in economical, effective grouting, if required, to provide an enhanced, economical rock bolting system of high efficiency.  The method of manufacture of the rock bolt from continuous weld cold drawn mechanical steel tube is also disclosed.

Granted: 1991-10-15
Abstract: ABSTRACT           The energy of a laser beam      is used to form images at intervals along a lengthwise moving web         The images  are  formed  along  a  plurality  of  axes  spaced transversely of the web so that after slitting and cutting an image appears on each sheet.   The laser beam      is directed  across  the  web  and  is  repetitively  and successively  switched  by  notating  optical  mirrors  in assemblies                    located at intervals across the web to scan image-bearing masks          rotating with the mirrors.   The beam impinges on respective mirrors of successive  assemblies.      The  mirror   assemblies  are conical mirror segments      or plane mirrors cooperating with a fixed conical mirror segment          to produce a focussed line      that is fixed in space and scans the rotating mask.    The scanning line is re-imaged (90) on the web

Title: Method for green liquor cleaning in sulphate pulp mills
Inventor: PETTERSSON BERTIL
IPC: D21C11/04
Filed: 1988-02-09
Granted: 1991-07-23
Abstract: Abstract Method for cleaning of green liquor from impurities consisting of solid particles.  Caustic lime, corresponding to 0.5-10% of the amount caustic lime necessary for complete causticizing of the green liquor, is added to the green liquor in the soda dissolving tank or in a separate mixing tank to which the liquor is led directly from the dissolving tank.  Calcium carbonate precipitates and forms with the impurities particles with considerably better settling- and filtration properties than the particles in green liquor which has not been treated with caustic lime.  The method makes it possible to use a considerably higher surface load than hitherto when clarifying the green liquor by settling in conventional green liquor clarifiers.  The method also makes it possible to filtrate the green liquor, e.g. in press filters, in place of clarifying it by settling in green liquor clarifiers.  The cleaning is much better than by conventional clarifying and consequently a decrease of the losses of degree of reduction during the causticizing process is obtained.

Granted: 1992-02-18
Abstract: ABSTRACT            A seamless tube-like blank is formed and cut into single annu-lar parts which consecutively are profiled by means of two tools having the shape of solids of rotation. During the profi-ling operation, the specific surface pressure on the inside and on the outside of the workpiece is equal. Preferably, an inner profiling roller and an outer annular profiling tool is used, the mutual distance thereof being variable. Simultaneously, the inner roller acts on the workpiece with its convex outer sur-face, and the outer annular tool acts on the workpiece with its concave inner surface. Thus, the effective surface pressures on the inside and on the outside of the workpiece are equal during processing thereof. The apparatus is is equally well suited for the manufacturing of steel rims and aluminium rims.

Title: Ripple-free flow, accurate mix, and automated spray system
Inventor: DYKMANS MAXIMILIAAN J
IPC: E04H7/24
Filed: 1988-05-16
Granted: 1992-05-19
Abstract: 176/85 ABSTRACT Processes and apparatus for the construction of improved tank structures employing pump metering and delivery system which accurately meters, mixes and evenly sprays composite materials to form the walls of tanks or containment vessels. Such systems have specific application to the construction of walls of prestressed tanks formed by inflating a membrane and applying rigidifying material outwardly of said membrane and then prestressing the walls by circumferentially wrapping prestressing material around the same. Promoters, catalyst, and other chemicals are used to create composite walls, each feeding into individual pump systems comprised of at least two hydraulic cylinders connected to supply cylinders which are coordinated so that their strokes are synchronized to arrive at a continuous flow. The flow is then channeled through a mixture which mixes the material for spraying through a nozzle. The flow from the nozzle can also be intermixed with chopped glass from a chopper system or with granular materials. Both the glass chopper system or the granular material feed system and the movement of the hydraulic system is controlled by a servo unit which can be synchronized to the desired volume of spray. The spray unit is moveably located on the tower which can ride around the tank as well as positioned itself vertically allowing for the continuous spraying of the walls of the tank. A computer can be used to synchronized the pumping rates, the chopper rates and for other considerations. The computer can also be used to monitor and store the output of the system.

Title: Bale bagging apparatus
Inventor: BRODRECHT GERRY
IPC: A01F25/14
Filed: 1988-11-02
Granted: 1992-03-10
Abstract: ABSTRACT OF THE DISCLOSURE          A bale  bagging  apparatus  for  bagging  round bales in tubes of plastic film includes a hoop and an annular flexible tube support projecting to the rear of the hoop.   The tube support conforms to the shape and size of the bales being bagged, so that a tubing may be used that is fairly close in size to the size of the bales.  This reduces the amount of air inside the bag and the ultimate looseness of the bagging tube on the bale, which affects its wind resistance and allows the bagging of bales in smaller tubes, which significantly reduces the cost of plastic film.

Title: Clutch/damper
Inventor: ESTABROOK ROBERT M
IPC: G05B19/40
Filed: 1988-11-07
Granted: 1992-03-17
Abstract: ABSTRACT         A clutch/damper for isolating and absorbing vibration induced reactive torques from adversely affecting a motor drive system.  A friction plate variably engages a gear coupled to the drive motor and to a load mass to permit normal drive in the absence of excessive reactive torque forces and to allow the motor to continue to drive against a slipping load in the presence of excessive reactive torque forces.  Feedback is employed in the drive system to compensate for the small errors induced by the slippage.  A position sensor responsive to an angular position of the load provides an error signal to an amplifier, which drives the motor in a direction to align the angular orientation of the drive motor and load mass, thereby reducing the error signal to a null value.  When applied to drive a moveable platform of a radar apparatus housing a receiver/transmitter and antenna, the invention substantially decouples the platform from the drive motor when reactive forces exceed an allowable level.
