Abstract: 375,974. Moulding hollow articles from synthetic resins &c. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABBIEKEN, 13D, Emmasingel, Eindhoven, Holland. June 8, 1931, No. 16658. Convention date, June 7, 1930. [Class 87 (ii).] Re-entrant hollow articles are formed from synthetic resin &c. by preliminarily moulding a non-re-entrant part so that the resin does not attain its final state, filling it with an incoherent and incompressible material, covering the exposed surface wholly or partly with material which may be preliminarily moulded, and uniting the parts, during or after which operation all the material is brought into its final state. In the example shown in Fig. 8, the portions 20, 23, 26, 29, 30 are successively moulded by stamps from resin brought to the B-state and are filled with sand cores 21, 24, 27. The whole material is then brought to the C-state and the sand cores may be removed through the apertures 32, 33, 34. The cores may be formed of ground marble or waste moulding material in the C-state and may contain pebbles to make them heavier. A layer of paper may be provided between the core and the moulded article. In forming an electric condenser according to the invention, the condenser 13 is supported in the preliminarily moulded housing 12 by ridges 14, the intervening space being filled with sand &c. 15 and the housing 12 is then united to the base 16 in a final moulding operation. The invention is also described with reference to the making of bottles.

Filed: 1974-04-17
Abstract: 1465102 Doping semi-conductor bodies BECKMAN INSTRUMENTS GmbH 17 April 1974 [17 April 1973] 16721/74 Heading H1K [Also in Division B3] Impurity material is introduced into a semiconductor body by subjecting it while in contact with the body to a centrifugal acceleration of more than 10<SP>8</SP>cm./sec<SP>2</SP> acting normal to the body surface. As described the process is carried out in a centrifuge having a hollow titanium rotor the inner peripheral wall of which carries a series of high strength sintered ceramic plates supporting a resistance heating cylinder which is provided with means for locating a number of semiconductor bodies, the rotor communicating with an evacuable rotor chamber into which gases can be controllably introduced. Typically phosphorus is first deposited on the bodies by decomposition of introduced phosphorus pentoxide, or gold or copper by evaporation from a source located centrally of the rotor. Then the temperature is raised, preferably to melt the impurity and the rotor spun at 60,000 r.p.m. to introduced it into the bodies. Subsequently the speed is reduced to 40,000 r.p.m. to cause surface alloying to provide ohmic contacts to which gold wires may subsequently be bonded in the same rotor using a speed of 20,000 r.p.m. The various operations may be speeded up by provision of a magnetic field parallel to the rotor axis.

Class 87(ii) A collapsable core for moulding hollow concrete and like articles comprises two half-core units dismountably connected endwise by rods 27 in each unit engaging sleeves 28 in the other unit. Each unit comprises a flexible sheath 7 enclosing an expanding and collapsing framework comprising two pairs of arcuate quarter sections 1, 2 and 3, 4 the members of each pair being hinged together at 5 and the free edges 6 of one pair being inset and fitting between the free edges 8 of the other pair. The sections 1-4 are reinforced by members 11 and 12 with which engage the ends of a number of spring clips 9 tending to collapse the assembly. The assembly is expanded in two directions at right-angles by longitudinal movement of a slide 13, expansion in the vertical direction in Fig. 1 being caused by inclined pieces 19 in the slide 13 engaging corresponding surfaces on the members 11, 12. Expansion in the other direction is caused by complementary inclined surfaces on the slide 13 and on a guide 14 within the slide causing relative lateral movement of the slide and guide, the slide pressing against the free edge 6 of section 1 and a part 18 of the guide 14, which projects through a slot in the slide 13, pressing against the free edge of the section 2. The sections 3 and 4 are simultaneously expanded by the sections 1 and 2. The guide 14 is attached at one end to a flexible plate 15 attached to the sections 1-4. As described, a number of cores are used in a moulding machine and the relative movement of each slide 13 and guide 14 is effected by a shaft 20 secured by a pin and slot connection to one end of the guide 14 and also secured to the slide 13. Axial movement of the shafts 20 is effected by slideways 25 on the machine. The shafts 20 carry sealing plates 24 and sleeves 23 which bear against flanges 26 on the slides 13. Moulding material is poured into the mould space through one or more openings in the top wall 29 of the mould. When the cores reach the end of their travel through the machine the slideways 25 and shafts 20 are moved outwards to collapse the cores and ultimately to withdraw the core half-units from the mould. The Specification as open to inspection under Sect. 91, states that the mould surfaces 29 between which the cores pass are endless aprons having parallel movements. This subject-matter does not appear in the Specification as accepted.
