The store 5 is provided with a plurality of chambers 6 and is rotatable so that the chambers 6 are moved in sequence past the end of a channel 3. The inserts 7 pass down the channel and into the chambers 6. When each chamber 6 has been provided with an insert 7, all the inserts are simultaneously pushed into a corresponding number of chambers 26 in the multi-station component 20 by plungers 81. The mould is now opened, i.e. the mould clamping plate 31 is moved away from the stationary mould clamping plate 1, and the component 20 displaced axially and then rotated about the axis 25 to bring the inserts 7 to the moulding position. After closing the mould, the moulding material is injected into the mould cavities through a duct 15. The mould is then opened and the component 20 rotated again to bring the moulded articles into the region of a discharge store 10. After closing the mould, all the articles are simultaneously pushed into the chambers 12 of the store 10 by members (75), the sprues 16<SP>1</SP> becoming punched out during this movement and being ejected by means 28 or opening of the mould. Auxiliary devices 100 used for handling the inserts 7 may also be pressed out at this stage by a plunger (71), Fig. 4 (not shown), the said devices passing through a bore (72). The articles are discharged from the chambers 12 on rotation of the store 10 and pass along a shoot 13. Several steps in the process take place simultaneously. Thus while the material is being injected into the mould cavities, another batch of inserts is being transferred to one of the other groups of mould chambers 26 in the multistation component 20, and a batch of previously moulded articles is being discharged. The apparatus may be used to mould only a single article at a time if the article has a plurality of inserts embedded therein.

Title: Improvements in and relating to electric incandescent arc devices
IPC: H05B41/19
Filed: 1916-03-04
Abstract: 152,694. British Thomson - -Houston Co., (Gerceral Electric Co.). March 4, 1916. Arc lamps; vacuum tubes; low-pressure metallic-vapour apparatus.-In a discharge device, such as a rectifier, having an incandescent cathode, this electrode is of strong construction and is heated to incandescence bv an arc between it and an auxiliary electrode before starting the main arc. In the form shown, the auxiliary electrode is a filament 8, which initially is heated by current from a special winding 13 on the main supply transformer 15 and is connected to the main anode. This connexion and the heating- circuit are opened by switches 24, 18 when the main discharge has started. The main cathode 3 is carried by a thin stem 2, the loss of heat in which may be diminished by reducing the stem to a thin neck just below the electrode 3. This and the auxiliary electrode 8 may be of tungsten, tantalum, molybedenum, or carbon, while the main anode 9 may be of the same materials or of vaporizable material such as mercury. In another device, the auxiliary electrode is pointed, and the starting-arc is set up by a high-pressure winding of the transformer. In a third arrangement, a high pressure for the same purpose is supplied through a resistance by an auto-transformer, and the auxiliary discharge is maintained continuously during working. Mercury or other vapour, or inert gases such as argon, nitrogen, krypton, neon, and hydrogen, at pressures varying from 5-12 mm. of mercury, for low voltages, up to an atmosphere, or more, are suitable for use in the devices. Oxygen, chlorine, water vapour, and the like should be excluded, although when the electrodes are of tungsten, molybdenum, &c., a trace of oxygen does no harm.
