Low-density crosslinked propylene polymer foams are prepared by mixing a propylene polymer with up to 20% of its weight of low molecular weight liquid polybutadiene(s) containing at least 35% by weight of 1,2-vinyl- polybutadiene and from 10 to 100% of its weight of EPDM rubber, EPM rubber or chlorinated polyethylene, together with a crosslinking or foaming agent, irradiating the mixture for cross...

Data is transmitted from an instrument 22 within a well 11 during drilling by provision in the drill string 12 of a clutch 23 which is operable by data signals from the instrument between a condition in which power is transmitted from a driving motor 17 to a bit 14 at the lower end of the string and a released condition interrupting the drive to the bit, with the data being transmitted to the surf...

There are described thermoplastic polypropylene pellets of improved processability containing a free radical source prodegradant which on remelting the pellets by extruding or the like, will react to further reduce the molecular weight as well as the molecular weight distribution of the polymer to a point where high capacity production of quality fibers and extruded products can be obtained. The f...

A process for forming a coating with a metallic finish, which comprises (1) A FIRST STEP OF COATING AN ARTICLE WITH [A] a water-thinnable paint comprising (a) a cross-linkable (meth)acrylate ester copolymer or a mixture of the (meth)acrylate ester copolymers containing at least 0.1 equivalent, per 1,000 g of resin solids, of a carboxyl or carboxyl ion group and a group capable of undergoing a ring...

Reservoir for storing deep cooled fluids, especially liquified gases, comprising a completely closed exterior container (2) of steel reinforced concrete or prestressed concrete and an inner steel container (5) for receiving the fluid, said steel container being open at the top and placed into the outer container with an insulating material inserted therebetween, whereby the insulating material ...

An electromagnetic article detection system of the type wherein a saturable magnetic target generates harmonics of an alternating magnetic interrogation field. A magnetic bias means is provided along with the magnetic interrogation field to promote the production of target response particularly at even harmonics, throughout the interrogation region.

An electric shaver with a trimmer is disclosed in which a single flexible seal is used to protect the motor and electric parts from water and other material entering through the perforated comb or the trimmer.

A surveillance marker has a semiconductor connected between arms of a dipole antenna, one arm being of non-ferrous conductive material and the other of high permeability low coercivity material such as permalloy. Higher coercivity magnetizable pieces are disposed adjacent the low coercivity arm, and all is sandwiched between paper or other insulating layers. The marker is detected by a combination...

A multiple jet aerator module or header which is formed substantially completely of fiber glass and which includes a right-circular tubular sheet-form liquid duct and a right-semicircular tubular sheet-form air duct having a radius substantially less than the radius of the liquid duct. Molded fiber glass liquid nozzles are located along the length of the liquid duct and a corresponding number of l...

A stirring installation for a liq. comprises a reservoir with a supply and return, (some of which is pumped back into the reservoirs); the supply being a vertical tube, immersed as deep as possible in the water, with one or more suction holes, (for air or another gas), in its wall at a determined distance above the surface of the liq. in the reservoir. The presence of kinetic energy from the retur...

A method of producing laminar structures, preferably consisting of fibreglass-reinforced polyester, which are free of air-pockets and pores, by spraying layers of the plastics and reinforcement fibres at a partial vacuum.
