Title: Device for measuring a linear dimension of moving articles
IPC: G01B11/04
Filed: 1959-08-10
Abstract: 884,643. Measuring article length photoelectrically. UNITED STATES STEEL CORPORATION. Aug. 10, 1959 [Sept. 18, 1958], No. 27299/59. Class 40(3). In measuring a dimension of a moving article having opposededges transverse to the direction of movement a trace on a cathode-ray (C R.) oscilloscope is produced as one transverse edge of the article travels a predetermined. distance and a pipon the trace is produced as the other transverse edge passes a predetermined point, the position of the pip with respect to the trace being an indication of the dimension. The embodiments described utilize obturation of photocells by the article and the trace is formed on a C.R. tube, and may be used in conjunction with a classifier in a machine with a flying shear to cut continuous strip into individual, sheets as described in Specification 795,480. Blocks 17, 18 have slots 16, 14, 15 so arranged that the distance from slot 14 to slot 16 is the maximum length within which a sheet S isacceptable and the distance between slots 14 and 15 is the allowable tolerance above which a sheet will be rejected as too short. A lightsource 27   is fixed above the sheet flow line and photocells are inserted as shown in the blocks. Block 18 is adjustable relative to block 17 by screw 19 to provide for differing acceptable maximum sheet lengths. When the lagging sheet edge uncovers slot 14 bi-stable multivibrator 30 is triggered to commence a sawtooth sweep by capacitor 37 and this sweep is terminated as that edge uncovers slot 15. When the leading sheet edge covers slot 16 the C.R. tube beam is deflectionmodulated via amplifier 43. Valve 33 H.T. is supplied by tachometer generator 31 to give a sawtooth rate of rise proportional to sheet speed so that the length of trace 47 is independent of sheet speed. A scale 45 is carried by a C.R. tube template 44 and carries a mark 46 denoting intended sheet length. In the second embodiment the "measurement band" is greater than the "tolerance band" and a first block having four slots and photo-cells is used, Fig. 3 (not shown).

Abstract: 518,248. Automatic circuit breakers. MASCHINENFABRIK OERLIKON. Sept. 22, 1938, No. 27591. Convention date, Oct. 1, 1937. [Class 38 (v)] An electrical switching device, comprising at least two automatic switches having plug or knife contacts for plugging into existing contacts, is provided with a coupling device between the several automatic switches so that disconnection due to overload or removal of one switch will bring about the disconnection of all the others in the device. In Fig. 1, automatic switches 22 which plug into existing contacts 23 each possess a plunger 6 and armature 4. Each armature is associated with a permanent magnet 3 attached to a connecting rod 2 spring-loaded by 8. On overload in one automatic switch, its catch 7 is tripped by means not shown, thus releasing latch 5 enabling pin 20 to strike projection 11 giving plunger 6 an impulse towards the magnets. This impulse is conveyed through connecting rod 2 to the other switches whose catches 7 will also be.tripped. In each of the switches the fall of the latch 5 allows toggle 17 to collapse and contact 19 separates under action of spring 18. If a switch is not fully inserted in its contacts then its catch will remain tripped due to action of spring 10 on the plungers. Catch 7 will also be tripped by the action of withdrawing one of the switches thus switching off all the others.

Title: Improvements in viscose process and improved low-shrink viscose rayon
IPC: D01F2/08
Filed: 1960-08-11
Abstract: Viscose is spun in an acid regenerating spin bath and the filaments are stretched progressively at least 90%, preferably about 100%, but not over 150% in a primary stage while in contact with the spin bath. They are then contacted while in an incompletely regenerated plastic state with an acid bath at 80 DEG -100 DEG C., preferably about 90 DEG C., containing 1 to 6% preferably about 4% by weight of sulphuric acid while stretching them an additional 5 to 50%, preferably about 30%, to completely fix and regenerate them prior to any relaxation resulting in filaments having an appreciable amount of "skin".  They are subsequently immersed in an aqueous solution containing 0,1 to 2% of sodium hydroxide at about 80 DEG  to 100 DEG C. while free from tension to effect complete relaxation of the filaments.  The completely regenerated filaments prior to washing may be cut into staple fibres, the fibres washed, immersed in a 1% aqueous sodium hydroxide solution at about 90 DEG C. for about five minutes, and then washed and finished in the conventional manner.  Conventional acid regenerating spin baths may be used, either the viscose or the spin bath containing an active regeneration retardant to ensure the formation of a high proportion of "skin".  A mixture of polyethylene glycol and dimethylamine, preferably in equal proportions of from 0,05 to 0,5% each based on the weight of the viscose, may be used as a regeneration retardant, as described in Specification 912,123.  The spin bath is preferably maintained at a temperature of 40 DEG  to 70 DEG C., and the stretching in the primary stage may be effected in the spin-bath itself or in the spinbath carryover.  The filaments have practically no shrinkage and can be converted into yarns and woven fabrics exhibiting dimensional stability during repeated severe laundering.
