[Class 130] A machine for making filter tips comprises one or more coiling devices mounted on a rotating wheel or a moving endless chain, a strip of paper or the like being delivered to the coiling devices, which rotate relatively to the wheel &c., and the coiled strip, the length of which may be sufficient for a number of tips, being subsequently ejected from the coiling device. As shown, the wheel 1 has four semi-cylindrical pockets 3, and at each end of the wheel adjacent to each pocket 3 is a bracket 4 provided with a bearing 5 for the spindle 6 of a coiling device comprising a pair of spring-controlled levers 9, 10 pivoted at 11 to the forked end of the spindle and bearing at their rear ends against a conical portion 16 of the bearing. Axial movement of the spindle 6 in its bearing is effected by means of cam plates 24 on the wheel, against which a disc 7 on the spindle is held by means of springs 20 connected to a bridge piece 19 carrying a coned member 22 engaging a recess in the disc 7. A pinion 17 splined on the spindle 6 is prevented by a bracket extension 18 from axial movement and engages arcuate racks 23 in order to effect rotation of the spindle. A strip 36 of paper or the like is drawn from a roll 37 and is gripped by the levers 9, 10 as the discs 7 ride off the cams 24. The portion of the strip gripped by the levers is severed by a rotary cutter 28, the spindle 6 of the coiling device is rotated as the pinion 17 travels on the rack 23, and the ends of the coiled strip are cut off by rotary disc knives 33 engaging in annular grooves in the wheel 1. The levers 9, 10 are released from the coiled strip by the axial movement of the spindles 6 effected by the cams 24, and in the bottom position 41 the strip is removed from the pocket 3 by levers 42 and falls on a travelling paper web 46, which is wrapped around the coiled strip by a former 47. The rod so formed can then be cut up into lengths corresponding to filter tips or multiples thereof. To prevent the unwinding of the coiled strip, paste may be applied to the strip at spaced points or lines by a paste roll 29 consisting of discs mounted on a shaft 30, behind which are a number of spring fingers 32 pressing against or close to the wheel 1 between the discs. In modifications, (1) the peripheral distance between the pockets 3 is less than the length of the strip, which is fed by rollers and slips over the periphery of the wheel ; (2) the feeding of the strip is effected by the rotation of the coiling devices, one filter filling being wound up before the paper is gripped by the following coiling device and then being severed. Specification 392,266 is referred to in the Provisional Specification, which states also that the paper strip may be crimped or corrugated.

Title: Improvements in and relating to radio and radar receivers provided with automatic sweep arrangements
IPC: H03J7/22
Filed: 1946-12-09
Abstract: 630,263. Automatic tuning correction; radiolocation. WILLIAMS, R. STUART-, and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 9, 1946, No. 36350. [Classes 40 (v) and 40 (vii)] A radio or radar receiver of the type in which the local oscillator is automatically swept over a band of frequencies by a sweep oscillator but is caused to lock when a signal is intercepted, is characterized by the provision of means for varying the sensitivity of the sweep oscillator so that locking occurs in respect of the frequency at which maximum power is generated by the transmitter. In a receiver (Fig. 1, not shown), as described in Specification 625,977, in which the local oscillator output is mixed with the transmitter frequency and after passing through a sharply tuned intermediate frequency amplifier is detected and applied via a video amplifier and diode V2, Fig. 3, to lock the frequency-sweep oscillator V1, the diode V2 is provided with an adjustable positive cathode bias. The bias is slowly reduced from the maximum value, which is sufficient to prohibit locking, and may be controlled manually by means of a potentiometer R2. In an automatic arrangement, Fig. 4, the bias is obtained from a condenser C which is charged up from the H.T. + line, but may be discharged slowly over a resistance R3 by operation of a relay RL. With either arrangement the sweep is stopped when the sensitivity increases sufficiently for the strongest transmitted signal to cause locking.

IPC: B01J37/03
Filed: 1956-11-28
Abstract: Active oxides of large specific surface area, i.e. a surface area greater than 10 m.2/gm., are obtained by reacting a salt of the appropriate metal in solution in a non-aqueous solvent, with a base at a temperature below the boiling point of the solvent, there being available in the reaction mixture at least x but not more than 5x molecules of water per salt cation, where x is the valency of the cation.  The desired active oxide is obtained as a precipitate.  The water may be water of hydration of the salt, and the solvent may be methanol or acetone.  The base is preferably anhydrous ammonia, although other bases, such as sodium hydroxide, potassium hydroxide, pyridine, and aniline, may also be used.  The reaction is preferably carried out between 0 DEG  C. and 10 DEG  C.  Cations specified are iron, chromium, manganese, nickel, cobalt, titanium, vanadium, molybdenum, copper, zinc, magnesium and aluminium.  In an example, aluminium trichloride hexahydrate was dissolved in methanol, and ammonia gas was passed into the solution, the temperature being maintained at 0 DEG  C.  The precipitate was washed with methanol to remove any ammonium chloride.  The product was a hydrated alumina Al2O3 3.4 H2O, with a specific surface area of 600 m.2/gm. In other examples, nickel chloride was dissolved in methanol and treated with potassium hydroxide to give hydrated nickel oxide of specific surface area 350 m.2/gm. and ferric nitrate was dissolved in acetone and treated with ammonia gas to give hydrated ferric oxide of specific surface area 300 m.2/gm.
