Title: Production of thermoplastic valve bags -  overlapping perforated longitudinal edges of plastic film, strip of fibres and fused strip of same polymer and welding together by rollers
Inventor: WIRZ PETER
IPC: B65D30/24
Filed: 1990-10-20
Abstract: A single or multiply thermoplastic film is processed for making into bags, and valve bags in particular, which have small perforations in one area to allow the escape of air when the bags are filled by compressed air; these perforations are covered with a porous layer bonded to the inside of the film; the bags are made e.g. by forming the film into tubing, inserting a valve or wrapping over the longitudinal edges of the film and welding and cutting off both those and transverse edges of the material. A strip which is pref. longitudinal is perforated with small holes; this is next advanced continuously and a strip of thermoplastic filaments and/or fibres (made of the same polymer as the film itself) is applied in suitable overlapping width; this latter strip of fibre mat is bonded to the film along teh edges by means of fused polymer of the same type as the film or mat. ADVANTAGE - The method produces the bags from the one material so that they are completely recyclable, and can even be used to make bags again.

Title: Silicon prod. used in mfr. of organo:silane(s) and chloro:silane(s) - comprises intermetallic phase of silicon, iron aluminium and opt. calcium mixed with silicon to improve conversion
Inventor: HALVORSEN GUNNAR
IPC: C07F7/16
Filed: 1990-11-20
Abstract: A Si-compsn. contg. Fe,Al, and (optionally) Ca, as an intermetallic phase when added to Si in amounts of 0.1-5% by wt. (esp. 0.1-1%) improves the reaction performance in the conversion of Si to chloro- and organosilanes. In this respect, the degree of conversion, productivity, and selectivity (eg the proportion of Si converted to monochlorotrimethyl-silane) are all enhanced. The intermetallic phases, FeAl3Si2 and   Fe4Si6Al4Ca are prepd. by reaction of the appropriate quantities of metals with Si in the molten state, and on cooling the intermetallic phase solidifies out. USE/ADVANTAGE- Improves the economics of the process of making Si derivs. by increasing conversion, selectivity, and productivity, also reduces quantity of by-products.  Specifically: A Si compsn was produced contg. 10%Si and 90% FeAl3Si2. This was pulverised to a particle size of less than 0.2mm and mechanically mixed with metallurgical Si at a  dose rate of 1:99. The doped Si was then reacted with MeCl at 300 deg C in a reactor under pressure. In a comparative test the same reaction was carried out using pure Si. Results (pure Si in brackets) Productivity g/hr 8.05 (6.10), selectivity % 85.8 (84.1).

Title: Using recycled shreds in filler of smokable material
Inventor: HEITMANN UWE
IPC: A24C5/18
Filed: 1991-03-09
Abstract: Surplus material removed from a first layer of smokable material to be formed into rod-like fillers is returned to the layer at a margin of the layer. The first layer is produced by drawing continuously from a source of smokable material and is transported along an elongated path wherein the first layer has two marginal portions. In a first portion of the path successive increments of the first layer are converted into successive increments of a relatively narrow and tall stream which contains a surplus of smokable material. The surplus is removed downstream of the first portion of the path and is returned to a oortion of the path upstream of the first portion. The returned surplus is added to one margin of the first layer so that it forms a second layer therealong and re-enters the first portion of the path.
