Filed: 1971-08-18
Abstract: 1360671 Toy aeroplanes TOMY KOGYO CO Ltd 18 Aug 1971 [21 Aug 1970] 38694/71 Heading A6S [Also in Division H1] A non-flying toy aeroplane has a batterypowered electric motor 8 within its fuselage 1 to drive a propeller 7 through gears, &c., 9-12, 13, 13' when a switch 31a, 36 is closed, and also to drive through a clutch 15, 17 to a sound producing device which simulates the chatter of a machine gun. The switch 31a, 36 comprises a conductive operating plate 31 journalled upon the propeller shaft 5 and carrya planet pinion 32 having the end of its shaft slidable along an arcuate slot 35 in the gearcase. The arrangement is such that when the propeller 7, Fig. 4, is turned by hand in the direction P, the plate 31, &c. is carried along so that the planet pinion shaft slides to the end of its slot 35, the contacts 31a, 36 are made, and the motor 8 is energized to rotate the propeller. When the propeller 7 is subsequently stopped by hand, the plate 31, &c. swings back due to inertia forces to the position shown, the contacts 31a, 36 are separated, and the motor 8 is thereby switched off. The motor 8 drives through a gear 9 to gears 10, 11 journalled on the propeller shaft 5, the latter meshing a gear 12 fast on a countershaft 6 driving through a friction wheel pair 13, 13' to the propeller shaft. A front disk 18 journalled on the countershaft 6 is slidden axially by hand actuation of a control lever (26), Fig. 1 (not shown). extending through the fuselage, into engagement with clutch dogs 14 on the friction wheel 13, to transmit drive through pulleys 22, 24 and a belt 25 to the aircraft wheels 23. The clutch dogs 14 contact a vibration plate 28, so that as the friction wheel 13 rotates the vibration plate emits a whir simulating the noise of a propeller. By pulling another control lever 27, clutch dogs 15 on the friction wheel 13 are engaged by radial lugs 17 on a second disk 19 journalled on the countershaft 6, the lugs 17 successively engaging a second vibration plate 29 to simulate the chatter of a machine gun. As an alternative to the vibration plate 28 for simulating the whir of a propeller, the propeller shaft 5 may carry two arms (48), Figs. 7, 8 (not shown), having axially directed extensions at their ends mounting free rings (480 which rattle against the inside of a surrounding housing (47) as the propeller, &c. turns. The speed of the motor 8 is varied by a fuselage-mounted gravity-actuated rheostat in the motor control circuit, Fig. 6 (not shown), consisting of a pivoted arm (39) with a weight (41) at one end which traverses an acuate resistor (42) as the aircraft fuselage is tilted from a horizontal to an upwardly-directed position and back. The arrangement being such as to increase the speed of rotation of the motor 8 and the propeller 7 as the aircraft is tilted upwards.

Abstract: 1451847 Converters VERFAHRENSTECHNIK DR-ING KURT BAUM 6 Sept 1974 [13 Sept 1973] 39060/74 Heading F4B [Also in Division C7] To reduce the smoke and fumes produced in the operation of a bottom blast converter, inert gas e.g. nitrogen, is blown through the bottom layers during charging of the converter with scrap metal and with molten matal. After charging with scrap, the converter is briefly returned to its upright position and the scrap preheated by combustion of the shielding gas normally introduced during the blowing, before returning the converter to the tilted position and blowing in inert gas during the charging with molten metal. The converter 1 is mounted within an enclosure 20 having a top opening co-operation with the hood 40 of a gas cleaning system, and auxiliary hood 43 co-operating with a closable side opening 25, a closable observation opening 23, and side openings 29, 30 for the slag bucket and ladle trucks. A closure carried by the slag truck closes one of these openings during pouring from the converter. A hydrocarbon shielding gas is fed to the sheaths 10 of the bottom tuyeres 12 through an outer plenum 9, oxygen or an inert gas being fed to the tuyeres 12 through a plenum 11. Controls 13, 14, 15 in the oxygen, nitrogen and hydrocarbon supply lines are operated automatically by the movement of the converter, so that oxygen and hydrocarbon is supplied when the converter is vertical, and nitrogen is supplied when the converter is tilted. Flaps 42 in the main exhaust gas conduit leading from the main hood to the gas washing apparatus reduce the suction in the main hood when the auxiliary hood 43 is in operation. A manual control enables the ratio of hydrocarbon and oxygen to be adjusted to provide preheating for the scrap.

The part 16 is of somewhat box-like section with a top plate 16a, side walls 16b and bottom flanges on the plate 16c, spaced apart to form a gap 22, in which the bar 23 is slidably located. To bear against the roof a top plate 26 is secured to the bar 23 and includes a bar 27 pivoting on the plate flanges. With a rotary cam wedge device the roof beam 15, 16 has a concave seating on its underside to bear on an accommodating convex upper part of the bar 23, or vice-versa.

No Patent granted (Sealing fee not paid), Retting.-In a process for netting bast fibres such as flax straw for spinning, the straw after de-seeding is placed in a tank to which water together with a portion of liquid from a previous first stage of the treatment is admitted at 25‹ C., this temperature being maintained for 12-24 hours. A portion of the liquor is then run off and may be used for the next batch. The tank is filled up with fresh water and the temperature slowly raised to 37‹ C. and maintained thereat until retting is completed, the whole operation taking from 3-4: days. The liquor is then run off to waste, and fresh cold water run in and the mass allowed to stand for ¢ to 1 hour. This water is then run off and may be used as the water portion of the next ret. The final washing liquor should be made alkaline as with sodium carbonate in order to neutralize acids produced by the retting operation. The straw is preferably placed vertically in the tank and a gentle circulation maintained during the process. The woody matter may be removed before the retting treatment commences and in this case either a bed of straw or a portion of the woody matter is introduced into the bottom of the tank to promote the growth of the retting agents.
