Title: Method and apparatus for blow moulding
IPC: B29C49/04
Filed: 1975-07-18
Abstract: 1480464 Two-stage blow-moulding OWENS ILLINOIS Inc 18 July 1975 [22 [July 1974] 30239/75 Heading B5A In a blow-moulding process, a parison is blown into a preform in a movable preform mould 40, and the preform is transferred for final blowing to a stationary final mould 30. The operation is as follows: after a preform 49 has been blown in the preform mould it is retained in position on blow tube 42 while the preform mould is returned to the parisonreceiving station 21 where it receives a further parison 22; this movement brings clamping means 46 into alignment with the neck of the preform, and closing of the preform mould about the parison also effects closing of the clamping means about the neck of the preform (Fig. 5); the pipe 42 is then retracted and the preform mould 40 is returned to the preform blowing station while the preform is simultaneously transferred to final blow mould 30 (Fig. 4). In another embodiment of the invention (Figs. 13-15, not shown) a slightly different geometrical arrangement of the apparatus is used to facilitate the moulding of large containers; in a third embodiment (Figs. 10-12, not shown) provision is made for stretching the preform prior to final blowing; and in a fourth embodiment, (Figs. 16-21, not shown) a different clamping and transfer mechanism is used, the synchronization of the process, however, being unaltered.

Filed: 1962-08-07
Abstract: 1,063,051. Electric calculators. COMMUNAUTE EUROPEENNE DE L'ENERGIE ATOMIQUE. June 12, 1963 [Aug. 7, 1962], No. 30250/62. Heading G4A. A transfer of data from an analogue computer to a digital computer is initiated if any one of 20 analogue variables exceeds its tolerance limits. Each time any analogue variable does exceed its tolerances a corresponding set of the analogue variables (from 1 to 20 in number) is transferred successively, via an analogue-todigital converter, to certain pre-assigned addresses in the digital computer. When the transfer is complete an " interrupt " instruction is sent to the digital computer causing it to leave its current programme and enter a socalled " analogue " programme to process the data transferred. The particular processing will, of course, also depend upon the particular variable that, by exceeding its tolerances, caused the transfer to take place. The results of the digital processing are fed back to the analogue computer. If more than one analogue variable exceeds its tolerances simultaneously, this fact is stored and the various transfers are effected sequentially in accordance with a built-in priority sequence.

IPC: H02P7/292
Filed: 1966-07-06
Abstract: 1,191,261. Control of D.C. motors. COVENTRY CLIMAX ENGINES Ltd. 5 Oct., 1967 [6 July, 1966], No. 30373/66. Heading H2J. The accelerator pedal 6 for the electric driving motor of an industrial truck is fixed to a U-shaped permanent magnet 10 having polepieces 11. A plate 12 extends between the polepieces and carries a germanium or silicon semiconducting probe strip 14 which exhibits the Hall effect. The probe is energized through leads 15, and its output voltage is taken from leads 16 to a transistor amplifier which supplies thyristor firing circuits for controlling the motor current. When the pedal is depressed against the force of spring 18, the probe 14 is positioned in parts of the magnetic field of successively increasing strength so that voltage on leads 16 increases to accelerate the motor. The motor current passes through cable 24 whose magnetic field opposes the field between the polepieces. The motor current is thus limited to a safe value. In some circumstances, amplification of the output voltage of the Hall plate may not be necessary.

[Also in Division H1] A thin-layer body of A<SP>III</SP>B<SP>V</SP> semi-conductors is formed from a starting wafer attached to a substrate and brought to the desired thickness by a chemical etching and polishing process. The active etchant is a free halogen or a halogencontaining substance. A polishing addition is included in the etching liquid. Specific etching liquids are: (a) aqueous cupric chloride, glycerine (polisher) and bromine; (b) glacial acetic acid {polisher) and bromine; (c) glacial acetic acid and chlorine; (d) chromium trioxide with one of saturated aqueous cupric chloride, saturated aqueous ferric chloride, concentrated hydrochloric acid, and with a polisher selected from concentrated sulphuric acid, concentrated phosphoric acid, or glacial acetic acid; and (e) aqueous ferric chloride and glycerine. Other polishing additives are glycol, glucose, starch and dextrin, gelatine, and gum arabic. The etchants above may be used on indium arsenide and indium antimonide. Fig. 1 (not shown), depicts an A<SP>III</SP>B<SP>V</SP> wafer attached to a ferrite substrate and which has been shaped from a rectangular wafer by contour etching. The wafer is then mashed overall with the exception of the central area 7 which is to be thinned to form the active area of a Hall plate. The mounted wafer (with others) is attached to a support in an etching centrifuge (Fig. 2). The support may be reciprocated along a line parallel to the axis of the centrifuge tube to ensure that all wafers are evenly sprayed. Manual or electro-optic control of etching is effected by including an indicator wafer mounted on a white ceramic tile as contrast base and with an initial thickness equal to the thickness of material to be eroded. Alternative arrangements such as shaking baths may be used to obtain uniform etching.
