Title: Casting device for fishing - has launching rod elastic tensioner carriage and hook
IPC: A01K91/02
Filed: 1973-10-30
Abstract: Two arms (L) pivoting on a base plate are connected at their other ends by a handle. Another two arms are attached to a sliding carriage (CH) which bears a spring loaded hook. A rod (T) is worked into a pig-tail at one end on which is hooked heavy elastic, attached to the same base plate as above. At the other end of the rod is held the folded line, hook, float, etc., to be cast. The tensioner arms (L) are moved forward bringing (cH) up to the pig-tail with which the hook engages. They are then moved back taking the rod (T) with it and tensioning the elastic. The hook is moved aside, releasing the elastic and allowing it to drive the rod forward with considerable force, launching the cast in a controlled manner. Maximum range is achieved when the base is set at 45 deg. to the horizontal. A weight, float, line, hook etc., may be case mechanically when the fisherman is so restricted for space that he cannot make a normal cast by hand.

Title: Polymers dissolved esp. in crude oil to reduce friction - by circulating in partitioned tank using ascending gas bubbles
IPC: B01F33/40
Filed: 1973-12-21
Abstract: A method of dissolving polymers in solvents consists of bubbling a gas through a portion of a slurry of polymer particles in the solvent, where this portion is partitioned from the remainder by a wall with open top and bottom, so that the slurry is caused to circulate vertically. Fresh solvent and polymer particles are pref. continuously added to the vessel, while the resultant polymer solution is removed and the gas is collected at the top and recycled. The slurry pref. contains 0.5-2% by weight of polymer particles, esp. a polymer having a mean molecular weight of 5 x 106 - i x 106, more specifically a polyisoprene having a mean molecular weight of 8 x 106 and crumbled to give it a diameter up to 25 mm. Esp. for dissolving polymers in a crude oil or its fractions to reduce the frictional resistance during pumping. The expensive operations of finely granulating the material before introducing it into the oil are avoided. In addition, the resultant damage, which frequently reduces the molecular weight, is also avoided.

Patent FR-2220190-A1 (FR)
IPC: B27K3/34
Filed: 1974-03-08
Abstract: Cellulose-containing material, which is wood or a solid product prepared from wood, for example plywood or hardboard, is preserved. The cellulose-containing material must be virtually free from attack by wood-destroying fungi before it is treated. The treatment is carried out in an aqueous system containing 0.01 to 0.4% by weight of an organotin compound. In this tin compound, three organic groups are bonded in each case by a carbon/tin bond to one and the same tin atom. The aqueous system furthermore contains a monoquaternary ammonium compound in an amount which suffices to disperse the organotin compound under the treatment conditions in such a manner that the wood or wood product is loaded with 0.15 to 1.5 kg of the organotin compound per m<3>. In this preservation process, a substantial amount of organotin compound is taken up by the inner parts of the wood or the solid wood product.

Inventor: DAVERIO JEAN-CLAUDE
IPC: C21B7/16
Filed: 1974-03-14
Abstract: The front part of the pipe is exposed to the high temp. of the furnace, and so is made of copper or copper alloy, and double walled for water cooling: the rear part, however, can be of steel, which is cheaper. Satisfactory results are obtained when all the following conditions are observed si,ultaneously a low carbon (0.25% by weight) steel is heated evenly (not more than 10% between inner and outer surfaces) to 600 degrees C only, and the brazing metal used contains no more than 45% by weight of copper (plus 45% silver and some cadmium and zinc): this metal melts at 575 degrees C plus or minus 20 degrees C.

Title: Strip calibre changing system - for multi cage tandem rolling mills
IPC: B21B37/26
Filed: 1974-04-24
Abstract: Appts. for controlling the calibre of a strip in a tandem mill with a series of cages, so as to change the calibre as required at any point without stopping the rolling mill, comprises means for controlling the operating speed of the first cage, means responding to the movement of the strip for detecting the arrival of the point of calibre change in a second cage in order to produce a change of operational speed of the first cage with respect to its final pre-determined speed and the final pre-determined speed on the second cage after the passage of the calibre change point into the second cage mill. Enables greater productivity to be achieved by enabling large spools of strip to be processed continuously with pre-determined changes of strip thickness of any given length, or alternatively permits sections of strip of different thickness to be welded end to end and rolled to a continuous strip of uniform pre-determined thickness.

Title: Machine to superimpose and package small containers - uses inclined conveyors to position containers and introducing wrapping sheets
IPC: B65B35/50
Filed: 1974-05-28

These conveyors are side by side, and are of a length and gradient, with the lower conveyor curved, so that two containers arrive together at the superimposing station (II). The pairs move onward, driven by side conveyors with spacing attachments. An inclined conveyor (14b) raises wrapping sheets (15) to arrive on a conveyor (14a) in synchronisation with the pairs of containers. The sheets are withdrawn individually from a magazine (16) by a system of rotating hooks and pivoted suction pads.

Title: Cooling drum for paper coating machine - has unevenly wound cooling coils or tapered skin for even heating
IPC: F28F5/02
Filed: 1974-07-05
Abstract: A cooling drum used in paper coating plant where a plastics layer is applied to the paper at 315 deg.C and cooled to 50 deg., uses a doubled wall, and the cooling liquid passes through the hollow drum spindle by inlet and outlet channels each end of the spindle and circulated between the double walls (1, 2). To increase the cooling effect, the liquid passes through a helical coil (12) between these walls. To ensure that the cooling effect is even from end to end of the drum, the coils may be unevenly wound, (13) larger at the beginning and smaller at the end. alternatively, the surface of the drum may be thicker at the entry end than the discharge end. In another design another layer (14) of a different coefficient of heat conductivity may be inside the outer layer, both layers being tapered.
