Title: Method for producing a tube having a wall containing over 60 % of a plastic material and having a body and a necked head, and resulting tube
Inventor: REBEYROLLE MICHEL
IPC: B29C70/76
Filed: 1993-12-15
Abstract: The invention disclosure relates to a process for manufacturing a collapsible tube with a wall containing more than 60% by volume of plastic material from a substantially cylindrical, or tubular, blank. The inside and outside layers of the tubular blank are of polymeric plastic material, and the tube has a skirt and a necked head. In the process a shaping operation is performed where an end portion of the tubular blank is necked by bringing closer together inner and outer tools, thus producing crumpled folding of the end of the tube. Prior to the shaping operation the blank is heated in order to bring the portion of the end portion to be shaped to a temperature at the time of the shaping operation which is at least equal to the melting point of the polymeric plastic material forming of the layers the inside and outside surfaces of the wall of the blank. The polymeric plastic material is thus in a viscous molten state at the time of the shaping operation. By virtue of the shaping operation, the crumpled folds are formed by simply bringing closer together the inner and outer tools so that when the folds are fully crushed between the tools and the folds are completely welded to each other, thereby producing the necked head and shoulder integral with the remaining skirt portion of the previously tubular blank.

IPC: B29L9/00
Filed: 1994-07-19
Abstract: An electrofusion coupler (14) is slid over one of two thermoplastic pipes (10, 12) each having a layer or layers of reinforced fibres (34) between the centre of the wall of thc pipe and the outside surface (38). The end surfaces are trimmed in a butt fusion machine and the resulting end surfaces (40, 42) are forced against a heater plate. The plate is removed and the end surfaces are forced together. Internal and external beads (50, 52) involving inward and outward flow of material result, the outward flow ensures that there is at the welded joint an inner layer (60) which is free from reinforcement fibres. The external bead (52) is removed and the coupler is slid over the butt fused welded joint and energised to cause it to become fusion welded to the outside of the pipe.

Title: Doll with simulated physiological functions
Inventor: PRACAS VICTOR MANUEL
IPC: A63H3/36
Filed: 1994-10-18
Abstract: A doll with simulated physiological functions, in particular a toy doll in the form of a teddy bear is described. The teddy bear has a head with eyes that can move and a mouth that opens and closes. A lower jaw pivots about a first axis to provide the opening and closing action of the mouth. A mechanical linkage means is provided, having a first portion pivotally connected to the lower jaw and adapted to pivot about a second axis which is spaced from the first axis. The mechanical linkage means is arranged to transmit a movement of the lower jaw to another part of the doll, for example to the eyes, whereby opening and/or closing of the mouth, for example when feeding the teddy bear, can produce a simulated physiological response from the doll, for example a responsive eye movement. The mechanical linkage means also actuates a sound generating means in the form of a mechanically operated bellows and an air-driven vibratory reed. The arrangement of the mechanical linkage means is such that there is a degree of unpredictability in the simulated physiological functions which enhances the long term play value of the doll and increases the enjoyment of a child. The play value of the teddy bear is still further enhanced by incorporating the simulated physiological functions of ingestion of solid and liquid substances, as well as bowel movements and urination. A cylindrical container having first and second chambers is provided in the body of the teddy bear. The first chamber is adapted to contain liquid substances, and the second chamber is adapted to contain solid substances. A separating means is provided in a throat region of the teddy bear for substantially separating liquid and solid substances inserted through the mouth of the teddy bear.

Title: Method for inerting waste by crystallisation
Inventor: FEBVAY CHOFFEL LAURENT
IPC: A62D3/33
Filed: 1994-11-10
Abstract: A method for inerting residues from the incineration of industrial or household waste or metal hydroxide sludge, whereby the toxic metals contained therein are stabilised and thus immobilised over the long term. The method includes the steps of heating a mixture containing the waste to be processed and one or more nucleating agents containing ferrous compounds in particular. Heating is performed under conditions such that a liquid-phase mixture also known as a molten mixture or melt is obtained, wherein at least 5 % of the Fe¿2?O¿3? oxides are converted into FeO oxides. The method further comprises the steps of controllably cooling the melt to give a solid in which the heavy metals contained in the processed waste are included within crystalline structures, and recovering the resulting solid. The heating step may include a phase of stabilising the mixture at a temperature which enables the complete liquefaction of the mixture to be processed.
