Title: Improvements in machines for decorticating fibrous vegetable material
IPC: D01B1/14
Filed: 1936-10-27
Abstract: 479,626. Decorticating sisal leaves &c. GOWANS, C. H. K. Oct. 27, 1936, No. 29129. [Class 120 (i)] In a machine for decorticating sisal leaves and other fibrous material, of the type in which the material is gripped at one end and is traversed laterally with the free end or ends in contact with a drum or drums having radial pins or other scraping devices, an intermediate drum 11, Fig. 1, driven at an intermediate speed is arranged between the slow running and fast running drums 10, 12. The material fed horizontally to the first drum is turned to a position to engage the drum surface by a share or like appliance 42 and is weakened at the place where it is bent by two wheels or discs 43, 44, Fig. 3, placed opposite each other and in a longitudinal plane one above and one below the material which engage and weaken the material but do not damage the fibres. The drums 11, 12 are provided with plates 9 to receive the material from the preceding drum and hold it temporarily to prevent too violent an action where the drum speed changes. The drum 11 is keyed on a central shaft 14, Fig. 7, driven from a countershaft 18 by a chain 16. The drum 10 is carried on a spider journalled on the shaft 14 and is driven through gearing 27 .. 30 therefrom while the drum 12 is secured on a sleeve 21 and is driven by a chain 23 from the shaft 18. The drums 11, 12 each rotate about three times as fast as the drums 10, 11. The material is fed to the machine on a conveyer 31 and is carried therethrough between endless chains 32, 33, Fig. 4, driven by gearing from the shaft 18 and provided with longitudinal guides 40, 41, the material being weakened by the wheels 43, 44 and bent upwardly by the share 42. The shaft 14 and the sleeves 21, 47 are preferably provided with ball bearings. The pins are retracted once per revolution while remote from their operative position to clear them of waste material. They are mounted on slats 48 carried by arms 49, 51 having a roller 53 which engages in an eccentric track 54 and serves to rock the arms 49, 51 so as to draw the pins inwards. Specification 416,045 is referred to.

Title: Process for dyeing cellulosic fabrics by the continuous method
Filed: 1955-10-14
Abstract: Cellulosic fabrics are dyed by the continuous method, the entire surface of the fabric being treated with a drop-forming liquid aqueous mixture of alkaline to neutral reaction containing a complex copper or nickel compound of a direct-dyeing azo-dyestuff and an amine of the formula <FORM:0817864/IV (c)/1> wherein R1 represents a hydrogen atom, a C1-C3 alkyl group or an oxymethyl group, R2 represents a hydrogen atom or a methyl group and n is a number not greater than 4, the dyestuff then being fixed on the fabric in a gaseous medium such as air, humid air or steam or in a non-aqueous liquid medium such as molten metal or a water-immiscible liquid. Specified amines are those of the formul  <FORM:0817864/IV (c)/2> The amines may contain impurities such as monoethanolamine.  The mixture may also contain anions of a polyphosphoric acid suitable additions for this purpose being tetrasodium pyrophosphate, sodium tripolyphosphate and hexsodium tetrapolyphosphate.  Impregnation of the fabric is preferably effected on a foulard, uniform distribution of the liquor and removal of excess liquor being effected by squeezing rollers.  The dyeing may be after-treated with formaldehyde or with a condensation product of formaldehyde with, for example, dicyandiamide, dicyandiamidine or cyanamide in the presence of a copper compound.  Examples are given. Specifications 676,584, 708,144, 732,925 and 737,800 are referred to.

Title: Esters of amino acids and peptides, and derivatives thereof
Inventor: ANDERSON GEORGE WASHINGTON
IPC: C07K1/06
Filed: 1959-08-28
Abstract: The invention comprises tertiary butyl esters of amino acids or peptides or of N-blocked derivatives of such amino acids or peptides in which the free amino groups are protected by groups such as carbobenzoxy, tosyl or phthaloyl.  The butyl esters of the N-blocked derivatives are prepared by reacting the latter in a solvent medium with an esterifying agent having the hydrocarbon skeleton of tertiary butyl alcohol or hydrolyzable thereto, e.g. isobutylene in the presence of an acid catalyst.  The butyl esters may also be prepared by reacting silver salts of the N-blocked derivatives with tertiary butyl iodide.  N-Carbobenzoxy blocking groups may be subsequently removed by catalytic hydrogenation, while both the former groups and N-tosyl groups may be removed with sodium in a liquid ammonia medium. The butyl esters may be purified by conversion to the phosphorous acid or butanetetracarboxylic acid salts.  The examples describe the preparation of tertiary butyl carbobenzoxyglycinate, tertiary butyl carbobenzoxy-L-tyrosinate, tertiary butyl carbobenzoxy-D-,L- and DL-phenylalaninates, tertiary butyl carbobenzoxy-DL-valinate, tertiary butyl glycinate, di-(tertiary butyl glycinate) butanetetracarboxylate, tertiary butyl L-tyrosinate, tertiary butyl DL-phenylalaninate, tertiary butyl D-phenylalaninate phosphite, tertiary butyl carbobenzoxy-L-leucinate, tertiary butyl L-leucinate phosphite, tertiary butyl glycyl-L-phenylalaninate, tertiary butyl carbobenzoxy glycyl-L-phenylalaninate and tertiary butyl phthaloylglycylglycinate; the preparation of phthaloylglycylglycine by treating tertiary butyl phthaloylglycylglycinate with hydrogen bromide in glacial acetic acid; the preparation of carbobenzoxyglycine by treating tertiary butyl carbobenzoxyglycinate with hydrogen chloride in diethyl phosphite; and the preparation of tertiary butyl carbobenzoxy-L-prolyl-L-leucinate by treating carbobenzoxy-L-proline with tertiary butyl L-leucinate phosphite.

A cartridge 10 has a cylindrical body 12 with an integral front closure 14 of hemispherical shape and reduced thickness and is closed at the base by a primer holder 20. The body 12 has a flange 16 to engage the cartridge chamber of the gun and the holder 20 has an annular bead 28 with a chamfered edge 34 to engage in a correspondingly shaped recess in the body 12. The propellant 44 is housed between a cupshaped recess in the holder 20 and an overpowder wad 46 with a depending flange 48. The case 12, holder 20 and wad 46 may be moulded from polyethylene and, to improve the gas seal, holder 20 and wad 46 are formed with annular beads 38, 50 respectively engaging the inner wall of the case. Between the wad 46 and the shot 18 is a friable, compressible wad 54, preferably made of a foam plastic or polyurethane. Radial grooves 58 in the nose 14 form lines of weakness along which the nose fractures. In a modification, Fig. 8, additional concentric grooves 60 are provided. In the construction of Fig. 10, the interior of the body 12 has a stepped diameter providing a shoulder 64 to co-operate with the bead 38. To facilitate its insertion in the case, the holder 20 is formed with a radius 68 at the edge of the skirt 36 and a radius 66 is provided at the mouth of the case. A spinning operation may be used to introduce the holder 20 into the body 12, during which operation the friction generates sufficient heat to melt the contacting surfaces and weld the holder to the body 12.

Title: Improved readout control circuit for digital data

Abstract: 981, 548. Digital data-storage: read-out. AMPEX CORPORATION. July 30, 1963 [Aug. 14, 1962], No. 30203/63. Heading G4C. The invention relates to re-aligning ostensibly parallel data bits read from a magnetic tape, to compensate for tape-skew and imperfectly-parallel reading-heads. Seven bits in parallel, read at 11, are passed through pre-amplifiers 13 and peak detectors 17 into bit registers 14 connected to read gates 15. Detection at 17 of the first peak to arrive results in a signal which passes through OR gate 18 to trigger one of two one-shot multivibrators 23, 24 depending on which of two AND gates 20, 21 is held open by a mode selector 26 (which will depend on the information density on the tape). The pulse produced by the triggered multivibrator 23 or 24 passes through an OR gate 27 (which also inverts) into both a passive delay unit 30 and an inverter 31. The outputs from the delay unit 30 and inverter 31 pass to an AND gate 33 which produces a strobe pulse from the part of the delayed multivibrator pulse lagging behind the undelayed multivibrator pulse. This strobe pulse enables the register read-out gates 15. The pulse from delay unit 30 also passes to a pulse generator 35 comprising a differentiating circuit and a monostable multivibrator to give a pulse having a leading edge coincident with the trailing edge of the pulse from delay unit 30, this pulse being used to reset the registers 14. Thus the beginning of the reset pulse coincides with the end of the strobe pulse.
