Title: A felt comprising a loop seam for use in the press section of papermaking machines and a method of manufacturing such felts
Inventor: LILJA ROLAND EVERT
IPC: D21F7/10
Filed: 1983-10-27
Granted: 1988-04-28
Abstract: A felt (1) for use in the press section of papermaking machines. The felt (1) consists of a woven base (7) preferably of two layers of threads extending in the machine direction of the felt and cross-machine direction threads interconnect the machine-direction threads. The woven base having a batt (11) needled onto at least one of its faces. The felt is manufactured to be installed in flat form but after its installation in the machine its ends are joined together to form an endless cloth with the aid of a seam (8, 9, 10) known per se. A flap (11a) of the ban or batts is arranged to cover the seam area. 
<??>The invention also concerns a method of manufacturing and installing the felt in the press section of papermaking machines.

Title: Feeding and tensioning device for a strap to be tensioned around a package
Inventor: BARTZICK GUNTER
IPC: B65B13/22
Filed: 1983-05-16
Granted: 1988-06-23
Abstract: Support and tensioning apparatus for a strapping band to be tensioned around a package. A band first pressed between a pair of wheels and advanced in a band guide that surrounds but does not contact the package. The band is subsequently retracted with its front end secured in place into a position against the package by reversing the sense in which the pair of wheels rotates, and is then tensioned with a separate tensioning wheel that rotates slowly and at high power. The strapping band is tensioned with a pair of wheels of which one wheel is an idler wheel and the other wheel is a tensioning wheel powered in the tensioning direction by a motor and with its shaft mounted in a pivoting lever in such a way that the wheel presses against the strapping band, which is to some extent looped around it, while the band is being tensioned and rests on the idler wheel, with a force that increases with the tension in the band.

Title: Solar energy collection system
Inventor: JESCH LESLIE F
IPC: F24J2/40
Filed: 1983-08-17
Granted: 1989-02-09
Abstract: A solar energy collection system, instead of using a closed primary loop in heat exchange relation with a secondary loop passes water to be delivered to the end user through the collector 3 prior to storage in a storage tank 6. The flow rate of water through the collector is varied by means of a pump or valve 4 so as to increase as the power available for collection increases. Furthermore unlike conventional systems where the amount of water in the tank 6 is maintained substantially constant, the level is allowed to vary within wide limits, the tank only being refilled when adequate power is available at the solar collector 3.

Title: Cementing tool for wells
Inventor: FREEMAN TOMMIE AUSTIN
IPC: E21B17/14
Filed: 1984-02-06
Granted: 1986-12-11
Abstract: A cementing tool for wells in a combination of a cementing or collar and a basket, comprising a sunstantially tubular mandrel (40) having a cement basket (170) disposed thereabout, the cement basket being maintained in a collapsed mode by an annular overshot (36) at the bottom of a coupling (26) at the top of the mandrel. A flapper valve assembly (80) is located within the mandrel, being maintained in an open mode by the presence of a fill-up tube (140) disposed in the valve orifice. The bottom of the fill-up tube is secured to a slidable ball seat (120) located below the flapper valve assembly. The ball seat is initially secured in place by attachment through a plurality of shear rods (150) to a tubular activating sleeve (160) disposed around the mandrel and under the cement basket, the activating sleeve being maintained in its initial position by contact with the bottom of the cement basket, which is fixed to the mandrel by a shear screw (174). To operate the apparatus, a tripping ball (not shown) is pumped down the casing to the ball seat, whereupon the casing pressure causes the basket shear screw, acted upon by the activating sleeve, to shear, the basket moving downward and out from under the coupling overshot. Continued application of pressure causes the activating sleeve shear rods to shear, allowing the ball seat to move to the bottom of the mandrel, and removing the fill-up tube from the flapper valve orifice, permitting the flapper to close.

Abstract: At the frame (1) rear is an articulated support (3), held firmly in the flat, rest position, or in the extended angled support position. A retainer in the rear wall (2) of the frame coacts as a hinge with a hook of the support. It is formed by a slit passing through the rear wall so that the hook can be pushed through it to adjoin supports (6,16) on the opposite long sides of the slit. The effective thickness of the hook over the internal spacing of the support is less during the rest and useful positions than during an intermediate position.

Abstract: A thread-cutting tool comprises a shank 10 for attachment to the spindle of a milling machine, the forward end portion of which shank is formed with a flat 12 recessed to provide a pocket for a flat cutting insert 11. The insert, which is triangular in this instance, has one edge formed with a line of threadform teeth of identical profile. The teeth project laterally for cutting engagement with a work-piece. The surface of the work-piece which is to be formed with a thread is mounted on a fixed work-table of the machine. The tool is rotated about the spindle axis and is simultaneously moved by the spindle in a path centered on the axis of the surface of the work-piece to bring the teeth of the insert into engagement with the surface and the spindle and tool are moved axially continuously by a distance equal to one thread pitch for each revolution of the tool in the circular path, so in one revolution of the tool in the path a number of complete turns of the screw-thread are formed equal to the number of teeth of the insert in engagement with the work-piece.

Granted: 1988-10-20
Abstract: Improved chemimechanical, particularly chemithermomechanical pulp, (CTMP) is produced by defibrating or refining chips, screening and dividing the screened pulp into fractions of mutually different fiber composition. The defibrated or refined pulp is divided in a first screening means by taking-out at least 30% by weight of the incoming fiber suspension as a first long-fiber fraction and a first fine-fiber fraction, this latter being divided in a second screening means into a second long-fiber fraction which is combined with the first long-fiber fraction to form a long-fiber fraction of improved properties, which is removed from the process, and a second fine-fiber fraction of improved properties, which is also removed from the process.
