Abstract: 488,767. Injection-moulding. TRIGGS, W. W. (Thermo -Plastics, Inc.) Sept. 2, 1937, No. 24047. [Class 87 (ii)] In moulding plastic material such as cellulose acetate by injection, the material is heated in one or more chambers 27, transferred through passages 44, 45 to one or more chambers 28 at a higher temperature, material in the passages 44, 45 is transferred to the chambers 27 by ejecting material from the chambers 28, and further material from the chambers 28 is injected into a mould cavity through the passage. The machine comprises a two-part mould 14, 15 with dies 10, 12 having injection gates 46 leading thereto from the passages 44, 45 which are adapted to come into alignment. The material is ejected from the chambers 27, 28 by pistons 29, 30. The pistons are carried by platens which, with the mould parts 14, 15 are mounted in an hydraulic press. The dies may be heated and cooled by fluid introduced by pipes 18, 19 leading to passages 20, 21. The chambers 27, 28 may be provided with steam jackets 32, 33 round which are provided passages 34, 35 for circulating heating fluid. A pre-formed core, such as a steering-wheel having a rim 1, spokes 2 and a hub 3 may be placed between the dies, and the rim and part of the spokes, as at 5, 7, may be coated with the material. After transfer of material to the chambers 28, the chambers 27 are re-loaded. Before injection, the mould parts are separated and flash is removed from the mould and gates 46 ; the material is then discharged from the chambers 28, pushing chilled material in the passages 44, 45 into the chambers 27, and is forced into the mould.

Class 40(7) [Also in Group XXXVI] To produce a photographic record of the cathode-ray tube (C.R.T.) display of a first electric signal over a period including and preceding the incidence of a second electric signal or a disturbance, the display is modified by the second signal (or disturbance) which also actuates a camera shutter operating means, and the C.R.T. has an after-glow sufficiently long to ensure that the ensuing record shows the first signal prior to the incidence of the second signal (or disturbance). In the embodiment described the output voltage of a mercury arc rectifier together with a stepped voltage is fed to the C.R.T. Y plates and a sawtooth time base voltage locked to the rectifier frequency is fed to the X plates, to produce a deflection-modulated display on e.g. ten sequential traces. The C.R.T. afterglow is such that as the end of the last trace is reached the beginning of the first trace has disappeared. In response to a disturbance of the rectifier output due to arc-back the C.R.T. beam is blanked and after a predetermined delay the camera shutter is-opened. A number of oscillographs, each corresponding to successive parts of an extended time base, and a camera for each oscillograph, may be provided.
