Abstract: 1,112,392. Impact ' rotational ' moulding. DOW CHEMICAL CO. 19 July, 1965 [23 July, 1964], No. 30531/65. Heading B5A. Articles are made by " impact rotational moulding" by charging an impact mould cavity with mouldable thermoplastic raw material, and moulding it by impacting a die into the cavity while one of the mould elements is rotated, the rotation being continued, preferably for a specific, predetermined number of revolutions past the fill point, after completion of the impact stroke until the second order transition point of the material is approached and substantial solidification is obtained. Such rotation preferably applies a torque which is inadequate to overcome the resistant forces generated by the material when solidifying, thereby preventing rotation, and is insufficient to score the moulded articles. The apparatus comprises a mould block with a mould cavity therein, a die capable of reciprocating into and out of the cavity, either the mould block or die being rotatable to apply a torque as specified above. The cavity may have fill point determination means whereby the rotating element may be rotated a specific, predetermined number of revolutions past the fill point.

Abstract: 1397743 Processing cake tobacco GALLAHER LTD 26 Sept 1973 [30 June 1972] 30808/72 Heading A2C A method of producing bar or tobacco flake comprises subjecting each preformed tobacco cake individually to heat and pressure and subsequently to positive cooling and pressure applied to the larger faces of the cake. The tobacco cake may be caused to travel through a sequence of stations including a loading station, a hot pressing station and a cold pressing station. The method may be affected by use of apparatus comprising automatic feed means e.g. conveyors 6, 7 which transport loose tobacco 9 to the top of a vibrating upright metering tube 10. Sensor 11 controls the height maximum and the base of tube 10 is fitted with an adjustable gate 12 which directs tobacco to the space between parallel horizontal conveyors 13, 14 of variable speed which determine cake thickness. A guillotine 18 may cut the cake proceeding from conveyors 13, 14 into individual cake 15A which are subsequently processed in cruciform devices (not shown) to effect the necessary heating, pressure and cooling.

Abstract: 387,056. Field control of D.C. motors. HEWITT, L. B., Woodhurst, Green Lanes, Palmers Green, London, and METROPOLITAN ELECTRIC TRAMWAYS, Ltd., 55, Broadway, Westminster. Nov. 6, 1931, No. 30833. [Class 38 (iii).] A tram or like motor is provided with a number of control devices operated in succession by the main current of the motor to reduce the field when the current falls below a predetermined value and reinstate it when the current regains a certain higher value. For this purpose the field-winding 10 is in series with the coils 12 of a number of relays 13 included in systems A, B, C. When the current in the winding 10 falls below a certain value the relay 13 of the system A closes, energizing a coil 14 in that system which closes a switch 15 to put a resistance 11 in parallel with the winding 10. As the current through the resistance 11 traverses only a portion of the coil 12 the relay 13 is not opened until the current attains a value greater than that which allowed it to close. If the current falls still further the systems B, C are brought into action in succession to cut out portions of the resistance 11. To prevent any system from being brought into action out of its turn the circuits of the systems B, C include switches 18 which are closed at the same time as the switch 15 of the preceding system. To ensure the switches 15 being opened in the right order as the current rises each of the systems A, B, is provided with a switch 19 in parallel with the switch 13 of that system and closed by the coil 14 of the next system.

[Class 38 (ii).] Vacuum or low-pressure apparatus, arrangement of.-In a rectifying or like arrangement comprising one or more discharge tubes such as neon lamps each having a cathode and two or more anodes, all the anodes, when the device is in operation, are in electrical connection through switching-in devices to points of a transformer winding which obtain the same potential at different times and each anode has its own switching-in device so that the anodes in one and the same tube may be switched in at different instants, thus facilitating the ignition. The arrangement illustrated comprises two rectifier tubes 1, 2 connected in parallel. The anodes 3, 4 of the tube 1 and the anodes 6, 7 of the tube 2 are connected as shown through resistances 9 .. 12 and switching-in relays 21, 24, 22, 23 respectively to the ends of the transformer secondary winding 13 of which the centre tapping is connected through the direct current terminals 14, 15 with the centre tappings of heating current transformers 16, 17 for the cathodes 5, 8, the primary winding 18 of the main transformer being connected through a main switch 25 to the alternating current terminals 19, 20. On closing the switch 25 the anodes are necessarily switched-in at different instants owing to differences of lag in the relays. The relays may be replaced by ordinary switches or by a drum arrangement for switching-in the anodes of the same tube in succession. Alternatively the winding 13 may be connected at one end through a single relay to the resistances 9, 11, and at the other end through another relay to the resistances 10, 12. The Specification as open to inspection under Sect. 91 comprises also an arrangement of a single rectifier with two anodes and with relays provided in the leads connecting the phase windings of the transformer to the terminal 14. This subject-matter does not appear in the Specification as accepted.

Abstract: A neck-ring mould assembly comprises a pair of separable neck-ring mould halves, and a one-piece top finish mould ring having an exterior tongue occupying matching grooves in the halves for its support, and means for supporting the mould halves for rotation about their common centre.  The assembly is composed of two halves 11, 12 clamped in semicircular holders 13, 14 (Fig. 1, not shown), which are slidably supported as rails 17, 18 anchored at their ends to a support ring 20 (Fig. 2, not shown) and normally urged to a closed position by four springs 21.  The mould halves 11, 12 close about a one-piece ring R which has an external tongue engaging matching grooves in the mould halves which thus support the ring. The mould halves are separated by the downward movement of an actuator plate 56 upon bell-cranks 27-30 which are pivoted to the slide rails 17, 18, and are associated with the holders 13, 14.

Three alternative types of tine are shown in Fig. 1. The double-tines 7, 8 are hairpinshaped, the bent portion 13 being within the wheel but the portions 9, 10 being free to turn about their axes. The tines may be joined to their neighbours by loops 22 or tangential straight portions 30, so forming a continuous wire formation which is embedded in the wheel and anchored by the bends 21, 29. The wheelbody is formed of plastic or ceramic material cast or moulded or it may be made in two juxtaposed halves which are cemented together with the tines in place.

Abstract: 869,068. Slide projectors. AGFA A.G. Sept. 15, 1959 [Sept. 26, 1958], No. 31490/59. Class 97(1) An optical slide projector includes an electric motor for driving both a fan and a slide changing mechanism and electromagnetic means including an election for coupling and de-coupling said motor and mechanism, which means comprises a coupling shaft in permanent engagement with the motor shaft and mounted on a carrier mounted on the shaft and pivotable by an electromagnet. In the projector shown a fan 3 is driven by an electric motor 4 on the shaft 5 of which is mounted a carrier 8 and a worm wheel 6 for rotating a shaft 10 rotatably mounted on carrier 8. The carrier and the shaft 10 are normally held in the position shown in Fig. 1 by a spring 20. However when the electro magnet 7 is energised by means of a temporary switch the lever 18 on armature 19 is moved downwards together with a lever 17 on the carrier 8 which is rotated until pinion 12 engages pinion 22 on a slide changing mechanism comprising parts 21-29. At the same time a switch 14, 15 is closed by pressure of disc 23 on the spring supported connection 14 which completes the electromagnetic circuit, and the motor drives the slide changing device through pinions 22, 12. After one rotation of the shaft 21 a projection on contact 14 enters a notch 24 in disc 23 thereby opening switch 14, 15 and cutting out electromagnet 7, and allowing spring 20 to uncouple the motor and the slide changing mechanism.
