Title: Blow moulding small containers at high production rate
IPC: B29C49/06
Filed: 1969-11-28
Abstract: Apparatus for blow moulding small containers has two sets of core pins (185) mounted on a rotatable shaft (134) between a pair of mould plates carrying a set of parison moulds (218) and a set of blow moulds (222).

Title: Loom for weaving tapes - having needles at each edge of the weave to retain the weft in the correct posn. for beating up
IPC: D03D35/00
Filed: 1972-10-05
Abstract: A tape weaving loom, having the shuttle mounted on the reed, has a weft retaining element positioned at each edge of the weave and arranged perpendicularly to the plane of the weave with their pointed ends directed upwards. The needles are pref. secured to radial arms extending from a drive shaft which is rotated by an crank arm actuated by a ratchet on the reed, to raise and lower the needles. In their upper posn., the needles engage the weft yarn and retain it during a subsequent pick of the shuttle and during beating up. The needles are lowered after beating up to release the weft yarn. Where two tapes are woven simultaneously, a pair of needles is provided for each tape and, pref. the sepn. of the needles is adjustable. Each pick of the weft yarn is prevented from taking up an arcuate shape due to movement of the reed during picking of the shuttle. Also, irregular tensions on the weft yarn, tending to narrow the tape, are prevented.

Title: Polyglycidyl(meth)acrylate mouldings - crosslinked after moulding with catalyst added prior to prepolymerisation
IPC: C08G59/00
Filed: 1973-11-13
Abstract: A very hard, transparent moulding is prepd. by (1) incorporating a ring opening and cross-linking catalyst to a vinylmonomer compn. at low temp. and polymerising the compn. to >=90; conversion at low temp. without activating the catalyst, using ionising radiation or light, (2) moulding the polymer and (3) heating the moulding to activate the catalyst and thus harden the polymer by introducing transverse bonds. The process is specifically for compns. contg. 1-100% glycidyl ester e.g. (meth)acrylate and 0-99% of >=1 vinyl monomer. The process allows incorporation of the catalyst at the initial stage instead of incorporation prior to moulding, while inhibiting premature crosslinking and maintaining the thermoplasticity of the polymer for moulding.

Title: Amplitude adjustment for geophone output signals - signal derived from each geophone in group generated by background noise
IPC: G01V1/24
Filed: 1975-04-30
Abstract: The amplitude adjustment takes into consideration changes of energy transmission due to the nature of the ground under the geophones. A signal is derived from each geophone, generated by background noises, and compared with a reference signal. Geophone outputs are adjusted in accordance with the ratio of the noise to reference signals, so that output signals generated by seismic energy in each geophone accurately represent the seismic energy which reaches the surface layer under the geophone. Unwanted or irrelevant frequencies are removed by filters before the amplifying stages. An average value for all the processed signals can be easily achieved if desirable.
