Title: Apparatus for producing folded metal strip material
IPC: B21D53/02
Filed: 1971-09-14
Abstract: 1370685 Corrugating; bending cutters VULCAN AUSTRALIA Ltd 14 Sept 1971 [14 Sept 1970] 42789/71 Headings B3E and B3W Apparatus for corrugating a metal strip 6 comprises a pair of pivotally mounted dies 21,22, Fig. 2, mounted on a frame 17, which fold the strip around anvils 36 and 27 respectively, Fig. 7, the anvils being adapted to move in opposite directions so that as one anvil moves from a strip engaging position to a position clear of the strip the other anvil moves from a position clear of the strip to a strip engaging position. In operation for making heat exchanger elements the die 21 is pivoted in a clockwise direction, Fig. 5, until the leading edge 75 of the die engages a section 8 of the strip intermediate louvre sections 7, the latter being formed by a stamping die 11. Further pivoting of the die 21 causes the strip to be bent around the anvil 36 and a deflector plate 78 attached to the die maintains the unbent strip in a relationship which is square to the folded part. At the completion of the folding operation and in sychronism with the die 21 pivoting in an anticlockwise direction, carriages 33 and 34, Fig. 7, mounting the anvils 36 and 37 respectively, move to the right. The anvil 36 is thus moved clear of the strip so that a support 39, on the carriage 34, can enter the last formed complete fold and the anvil 37 can be positioned immediately above the last complete fold. The carriages are carried so that the carriage 33 moves upwards and the carriage 34 moves downwards, the latter movement feeding the folded strip downwards in readiness for the next folding operation. The folding die 22 then moves in an anticlockwise direction, Fig. 2, so as to fold the strip around the anvil 37. A second support can be mounted on the underside of a carriage (Fig. 11) for co-operation with a shearing knife set to operate automatically after a given number of folding operations.

A rotary sprayer for attachment to aircraft or other vehicles consists of a fixed perforated spindle 10, closed at one end at 46 and supplied with liquid at the opposite end by a pipe 59, on which spindle is rotatably mounted a guaze atomizing cylinder 37 driven by a windmill 16 attached thereto. The blade pitch of the windmill is adjustable and a brake mechanism is provided to restrain rotation of the cylinder despite airflow over those blades. The spindle is disposed horizontally fore and aft of the aircraft, and is carried by a bracket 11, Fig. 4, attached by clamps 61, 62 to the front and rear spars 12, 13 of the aircraft wing. The cylinder comprises separate cylindrical metal gauzes 48 attached to annular plates 36, 49 and 50 extending from a perforated drive tube 38. The rotary assembly is carried on bearings 18 and 43, the former being embraced by the hub 17 of the windmill and the latter by a housing 42 attached to the cylinder. An end plate 33 on the cylinder is attached to the said hub, and the latter consists of split halves 20 and 21 clamped together by a ring of bolts, and haying suitable bores therein to receive the root ends 23 of the blades 19. Thus by loosening those bolts the blade pitch may be adjusted. A brake drum 26 is attached to the hub by the said ring of bolts, and a bush 15 on the spindle carries brake shoes 30 which may be brought into engagement with the drum by a lever 31 and cam mechanism, or hydraulically, by the aircraft pilot.

Abstract: 1328022 EHT supplies ATES COMPONENTI EIETTRONICI SpA 15 Sept 1971 [22 Dec 1970] 42948/71 Heading H2F In a high voltage supply for the cathode-ray tube of TV equipment, the high voltage transformer receives flyback pulses from the horizontal deflection circuit, an oscillatory circuit L1, Cl, tuned to a harmonic of the flyback pulse is coupled to the high voltage transformer, the ratio of the harmonic to which the oscillatory circuit is tuned to the fundamental of the flyback pulse being varied as a result of changes in the current flowing in the high voltage circuit. As described, inductor L1 is variable by action of control current in winding L3 (Fig. 4) on its magnetic core. The oscillatory circuit L1, C is normally tuned to the fifth harmonic of the flyback frequency when the beam current is zero i.e. when the current in transistor T1 is determined by the ratio of resistors R1, P1. As the beam current increases, the current in winding 2 (Fig. 4) causes an increase in base current of T1 which de-tunes circuit L1, C so as to compensate for drop in EHT voltage. The EHT may be provided by means of a voltage tripler connected to winding 2.
