Abstract: 816,368. Rotary drum filters. OLIN MATHIESON CHEMICAL CORPORATION. Dec. 31, 1957 [Jan. 8, 1957], No. 40432/57. Class 46. In a rotary drum filter a top layer of the filter cake is removed from the drum and the remaining cake is removed and formed into a slurry, separate from the feed slurry, and is applied to the filter cake formed on the filter cloth emerging from the feed slurry. A filter cloth 25 on a rotating drum 23 picks up a layer of cake 39 from the feed slurry pan 20 over the sector A. While travelling through sector B a flinger 15 sprays a layer of reclaim slurry from the trough 14, fed from the pan 12, forming a layer of cake 42, on the cake 39. Over the sector C sprays 31 wash the filter cake and over the sector D the top layer of cake is first removed by an adjustable knife 33 and falls down a shoot 37 after which the remaining filter cake is removed by the combined effect of air pressure and sprays 32 forming the reclaim slurry in pan 12, a seal 20a preventing the reclaim slurry from entering the feed slurry pan 20.

Abstract: 983, 190. Recording and playback systems. AMPEX CORPORATION. Oct. 31, 1962 [March 30, 1962], No. 41245/62. Heading G5R. [Also in Divisions H3 and H4] A magnetic tape recording and playback system provides two signal recording channels (see Fig. 1) one of which applies the input signal directly to the tape (the DR channel), the other produces a signal which is applied to the tape after being frequency modulated in accordance with the input (Fig. 3 not shown), (see also Division H4). Either signal is applied to the tape in combination with a variable bias signal from a bias source 24. The system enables both DR and FM signals to alternate in the same record. The playback channels (Fig. 2) are designed so that when frequency modulation recording has been used it may either be demodulated in an FM playback channel or applied to the playback output directly through the DR playback channel.

A composite acrylic fibre comprises at least two different acrylonitrile polymers having different thermal shrinkages and arranged in lamination along the length of the fibre and eccentrically in respect of the fibre axis, wherein the fibre possesses potential coil crimps which could be developed upon heating and exhibits a rate of shrinkage of 5 to 20% and a shrinkability of at least 30 mg./d. when immersed in hot water at 98 C. Acrylonitrile polymers are defined as containing at least 50% acrylonitrile, and ethenically unsaturated copolymerizable monomers which may be present include alkyl acrylates and methacrylates, acrylamide and methacrylamide, acrylic acid and methacrylic acid, vinyl acetate, vinyl chloride, vinyl pyridine, and methallyl sulphonic acid and its salts. Such a fibre may be made by extruding two or more dissimilar spinning solutions of different acrylonitrile polymers having different thermal shrinkages simultaneously through a spinning nozzle in a coagulating bath to form composite filaments, stretching the composite filaments for orientation, subjecting the filaments to a structure collapsing treatment, heat treating the filaments in a relaxed state, and further stretching the filaments. Initial stretching may be to 5 to 15 times the initial length and conducted at a temperature of 80-150 C., e.g. in hot air, steam or a liquid medium, e.g. hot water. Suitably the structure collapsing treatment is conducted by drying the fibres in a drying atmosphere until substantially all of the water has been evolved from the fibres. Relaxation may be conducted at 100-160 C. Final stretching may be to 1À05 to 125 times the initial length and may be conducted at 100- 260 C. In examples:-(1) a copolymer of 90% acrylonitrile and 10% methyl acrylate and a copolymer of 88% acrylonitrile and 12% methyl acrylate are separately dissolved in 50% aqueous sodium thiocyanate to prepare two spinning solutions which are extruded at equal rates through a suitable spinneret into 8% aqueous sodium thiocyanate. The tow is washed with water, stretched 8 times in boiling water, dried in a humid atmosphere to a moisture content of less than 3%, relaxed in boiling water for 10 mins., crimped, dried, and stretched 1À07-1À22 times at 120 C.

The handle 1 mounts a support 8, carrying a thrust member 9 and front and rear guides 7, 7a, through which a carriage 6 having a container holder 10, can slide. The container 11 is secured to the container holder 10 and may have a nozzle member 15 or be arranged to engage a nozzle member 15 which is supported on holder 10. The container 11 is generally cylindrical, and is constructed of a material which can be easily cut. The thrust member 9 has a ring-like portion 9a which has a sharpened leading edge, used in severing the base portion from the container wall, for use as the piston 12. The thrust member 9 is secured to the support 8 by a portion 9d which is sharpened on its leading forward edge to slit the container. The quantity of substance dispensed is controlled by an adjustable stop-means at the base of the handle, which comprises a stop member 3 in a screw threaded engagement with a screw adjustor 4 engaged with the base of the handle, and engageable by a portion 2a on the trigger. When the container 11 is empty, a further plunger 23 may be secured to the member 9 (Fig. 8 not shown) to project into the nozzle 15 whereby further operation of the trigger 2 will discharge the remaining material from the nozzle. The movement of carriage 6 is effected by front and rear gripping members 16 and 17. A spring 20 is located between the gripping member 17 and guide 7a. The trigger 2 has an upwardly extending lug portion 2b which is located between gripping members 16, 17 and the grip member 17 has a forwardly extending portion 17a linked by a pivotal connection 21 to trigger 2. When the gripping members 16, 17 are angularly displaced by the trigger 2, the aperture edges move between a binding and non-binding position with carriage 6 to allow the carriage to be moved, locked in position or move freely.
