Title: Method and apparatus for fabricating pile goods
IPC: D04H11/04
Filed: 1971-09-16
Abstract: A method of, and apparatus for, the fabrication of pile goods in which the pile material is introduced through the intermediary of an infeed sword member into the spaces formed between radially extending lamellae located about the periphery of a revolving drum. During introduction of the pile material into these spaces, this material is fixedly retained relative to the drum by holding means in the form of a holding sword member. The infeed sword member and the holding sword member are moved towards and away from the drum and during their work position at the drum while in the neighborhood thereof such are moved in the direction of drum rotation and during their rest position when remote from the drum they are moved back opposite to the direction of drum rotation. The holding sword member is introduced into a space at the peripheral surface of the drum before or directly after the infeed sword member has been withdrawn from such space, and then the holding sword member is retained in this space for such length of time until the infeed sword member has been introduced into the next space, whereupon these operations repeat. The invention is also directed to pile goods produced in accordance with the inventive method.

Title: Vinyl halide polymerization process and reactor therefor
IPC: C08F2/18
Filed: 1977-12-23
Abstract: Build-up during vinyl halide, particularly vinyl chloride, polymerization is prevented by employing a reactor having an adherent internal coating of a product derived from the admixture of at least polyethyleneimine and one or more of hydroquinone, p-benzoquinone, catechol and o-benzoquinone.

The chemical constitution of the resulting coating product is not properly understood but is thought to include aminoquinonoid structures, condensates and radical anions. One embodiment is directed towards low temperature formation of the coating product in the presence of oxygen and on the reactor surface. Another embodiment concerns preforming the coating product and then applying it to the reactor surfaces.

Title: Frictional engagement system incorporating an aluminium friction surface.
IPC: F16D69/02
Filed: 1978-09-14
Abstract: A frictional engagement system, particularly a brake system, comprises two friction surfaces, one of which is composed of aluminium, the other of which is formed of a lining material which incorporates sodium fluoride or cryolite. When the system is subjected to repeated frictional engagement, as for example braking actions, the additive of the lining reacts with a surface layer of the aluminium friction surface to form a tenacious, wear-resistant layer thereof. The additive, upon further engagement serves to maintain the wear-resistant layer as fresh aluminium is exposed during normal wear of friction surface over its useful life.

Title: Polyolefin-metal bonded structures and process for preparing same
IPC: C09J201/00
Filed: 1978-11-15
Abstract: When a polyolefin layer is bonded to a metal substrate through a primer layer, if a polar group-containing ethylenically unsaturated monomer-modified olefin resin (A) having a specific polar group concentration and a specific degree of crystallinity and a coating film-forming base resin (B) are incorporated at a specific ratio into a specific mixed solvent to form a paint and the primer layer is formed by using this paint, there is obtained a novel multi-layer distribution structure comprising the base resin distributed predominantly in the portion of the primer layer contiguous to the surface of the metal substrate and the modified olefin resin distributed predominantly in the portion of the primer layer contiguous to the polyolefin layer and having a concentration gradient of the two components (A) and (B) in the thickness direction. By virtue of the presence of this primer layer, the bonding strength between the metal substrate and the polyolefin and the corrosion resistance of the metal substrate as well as the processability of the polyolefin-metal bonded structure are substantially improved.

Title: A device for rotating the blade-carrier in an apparatus for comminuting foodstuffs
IPC: B26D3/26
Filed: 1980-02-07
Abstract: The neck 16 of a housing 1, fig 1, of an onion etc. comminuting apparatus is formed internally with steep helical guide grooves 15 between ribs having flanks 18, fig 2. A member 13 is reciprocable up-and-down by manual and spring force and carries resilient projections 14 which tend to spring out to a radius 19 greater than the radius 20. When the member 13 is driven down the projections 14 are pressed radially inwards (arrow 22) and ride over the ribs so that the member 13 does not rotate. As the member 13 rises the projections 14 engage respective flanks 18 and are driven as indicated by the arrow 23 to rotate the member 13, the latter being connected to the blade-carrier 5, fig 1. In a modification, fig 3 (not shown), the projections are replaced by raised wall parts each associated with an axial slot and an adjoining radial slot.
