Title: Moulding three layer soles onto shoe uppers
Inventor: PFEIFFER HANS JOACHIM
IPC: B29D35/08
Filed: 1991-04-30
Abstract: Moulding soles onto shoe uppers, the soles comprising a bottom sole, an upper sole and an inner connecting sole, uses a two-stage process. In the first stage, a last carrying the shoe upper, which may be textile, elastomeric or thermoplastic material, is placed on the shell-type bottom die and a shaped contour plate inserted to divide the side mould parts into two mould cavities for the bottom sole and upper sole respectively. The upper and lower soles are moulded, the upper sole combining with the shoe upper, by injection of material through sprue bores; suitable materials include polyethylene, PVC or polyurethane. In the second stage, the contour plate is removed from the mould and material forming a softer "comfort" inner sole, such as a soft polyurethane, is injected through sprue bore into the enlarged cavity, being moulded onto the surfaces of the upper and lower soles. Pref. the contour plate is supported on the edge of the shell-type bottom die and on an undercut of the side mould parts, with the dimensions of the part surrounded by the edge of the bottom die corresponding to the dimensions of the inner sole. The contour plate is made by first making a blank which is then machined to give the required bottom sole mould cavity, after which a layer of material having the contour of the upper sole cavity is applied to the blank using the mould such that it has the dimensions of the inner sole to be moulded.

Title: High-density polyethylene (HDPE) prodn. - with procedure for changing process parameters to enable changeover from high-mol. wt. to low-mol. wt. HDPE without shut-down or cleaning
Inventor: FRITZSCHE GERD DIPL CHEM
IPC: C08F10/02
Filed: 1992-12-10
Abstract: A process is claimed for the prodn. of HDPE by catalytic gas-phase polymerisation of a mixt. of ethylene, hydrogen and comonomer in a fluid-bed reactor incorporating a gas distributor, with recirculation of unreacted gas mixt.. The special feature is that, from the steady-state condition for prodn. of a polymer suitable for the mfr. of large tubular prods. (HDPE-I), the system can be changed over directly to reaction conditions for the prodn. of a polymer suitable for the mfr. of film, fibres and injection mouldings (HDPE-II), by changing the catalyst and the comonomer but without shutting down or cleaning the system. This process comprises: (a) raising the hydrogen concn. in the gas circulation to a level corresp. to a hydrogen/ethylene mole ratio of 45-55 x 10 power(-3) mole/mole 36-42 hrs. before changeover, at a temp. of 84-96 deg.C and with continuous removal of off-gas at the rate of 1.7-5.1 x 10 power(-3) Nm3/m3 circulating gas, (b) stopping the addn. of catalyst, (c) emptying the catalyst metering system including instrument parts, washing with the new catalyst and filling with new catalyst, (d) stopping addn. of comonomer (e.g. butene-1) when monomer conversion has dropped to 20-30% of the normal level, (e) preparing for the change of comonomer, e.g. from butene-1 to propene, (f) adding a mixt. of N2/O2 to kill any residual reaction (at the same time as (d)), (g) flushing the reactor 2-4 times with ethylene, (h) establishing the required new hydrogen/ethylene ratio (the propene content is adjusted only after the start of polymerisation), (i) starting addn. of the new catalyst, with the circulating gas contg. less than 1 ppm oxygen and less than 3 ppm CO2, (j) lowering the reactor fill height to 90-94% of the normal level gradually over 1.4-1.8 hrs. (simultaneously with (b)), (k) raising the reactor temp. gradually to 94-96 deg.C starting with (b), (l) increasing the reactor level to 110-115% of normal for 15-35 mins. after stage (i), and (m) re-establishing the normal reactor level. USE/ADVANTAGE - The invention makes it possible to convert a continuous gas phase HDPE prodn. system directly from prodn. of high-mol. wt. polymer to prodn. of low-mol. wt. polymer (mol. wt. 300,000) by changing the catalyst and the comonomer but without shutting down or cleaning the system. This process reduces the amt. of transitional polymer with pinholes and inhomogeneities which is normally obtd. after changeover.

Title: Hanger for flat objects
IPC: A47G1/24
Filed: 1993-02-25
Abstract: When hanging up pictures, for example, very precise mounting of the conventional triangular hanging members is required in order that the picture does not hang crooked. A correction is possible only by re-mounting. In the case of hangers having a trapezoidal hanging member, correction of the picture so that it hangs square is possible, but the arrangement is aesthetically unsatisfactory since the hanging member is not seated centrally on the wall hook. The new hanger is to have a lateral-adjustment facility which is not visible. Adjustment is possible by virtue of the fact that the hanging member (3) is no longer rigidly connected to the fastening plate (1) but is displaceable in the longitudinal direction on it, this being concealed to the observer by the picture frame (5). It is also possible to lock the hanging member into place in various pulled-out positions owing to a toothed engagement with the fastening plate. Hanging of pictures, text-carrying boards, mirrors, etc. <IMAGE>
