Abstract: The invention comprises a compound of the formula <FORM:0802548/IV (b)/1> and a process for its manufacture, wherein L-leucyl-glycinamide is reacted (e.g. in the presence of an ester of chloroformic acid and a tertiary base) with N-carbobenzoxy-L-proline to form the N-carbobenzoxy derivative of a tripeptide which is converted, by splitting off the carbobenzoxy group, to the free tripeptide of formula II, <FORM:0802548/IV (b)/2> further L - asparaginyl - S-R-L - cysteinemethyl-ester, where R is a protecting group such as phenyl, benzyl, p-bromobenzyl, p-tolyl or p-xylyl, acylated with N-carbobenzoxy-L-glutamine (e.g. in the presence of an ester of chloroformic acid and a tertiary base) and the tripeptide ester thus formed, whose free amino and mercapto groups are protected, is converted into the azide of formula III <FORM:0802548/IV (b)/3> which is reacted with the dipeptide II to yield a hexapeptide, which after splitting off the N-carbobenzoxy group, corresponds to the formula IV, <FORM:0802548/IV (b)/4> further N-R1-S-R11-L - cysteinyl - L - tyrosine, wherein R1 denotes a protecting group such as benzenesulphonyl, toluenesulphonyl, carbophenoxy, carbobenzoxy, or carbo-p-bromobenzoxy group, and R11 represents a protecting group such as a phenyl, benzyl, p-bromo-benzyl, tolyl, or p-xylyl group, is condensed with L-valine methyl ester to form the ester V, <FORM:0802548/IV (b)/5> this is converted into the corresponding acid or reactive derivative thereof which is reacted with the hexapeptide IV to form the nonapeptide VI, <FORM:0802548/IV (b)/6> and finally the groups R, R1 and R11 are split off by treatment with an alkali metal, preferably sodium or potassium, in liquid ammonia, to yield the free nonapeptide which on oxidation with air in an aqueous solution at pH 6-8 yields at room temperature the product of formula I.  Examples illustrate the various modifications of the process.  Starting materials. L-Leucyl-glycinamide is prepared by reacting N-carbobenzoxy-leucine with glycinamide in the presence of an ester of chloroformic acid and a tertiary base followed by splitting off the N-carbobenzoxy group. L - Asparaginyl - S - benzyl - L - cysteine methyl ester is prepared by converting S-benzyl-L-cysteine into its methyl ester hydrochloride, reacting this with N-carbobenzoxy-L-asparagine and splitting off the carbobenzoxy groups.  N-R1-S-R11-L - cysteinyl - L - tyrosines, wherein R1 is benzene-sulphonyl, carbobenzoxy, and carbo-p-bromobenzoxy, and R11 is benzyl, are prepared by reacting N-R1-S-benzyl-L-cysteine with L-tyrosine-methyl ester in the presence of dicyclohexyl-carbodiimide, and saponifying the ester so produced, also, wherein R1 is carbobenzoxy and R11 is p-bromobenzyl, phenyl and tolyl, by treating S-R11-L-cysteine with carbo-benzoxy chloride, and reacting the N-substituted amino acid with L-tyrosinemethyl ester in the presence of diethyl phosphite and tetraethylpyrophosphite and saponifying the methyl ester so produced.

Title: Improvements in or relating to a rewinding apparatus for the rewinding of web-like material
IPC: D06B3/32
Filed: 1968-07-01
Abstract: 1,235,493. Feeding webs. MASCHINENFABRIK BENNINGER A.G. 1 July, 1968 [3 July, 1967], No. 31342/68. Heading B8R. [Also in Division F2] In apparatus, e.g. dyeing machines, in which a web of material can be wound from one roller on to another, and vice versa, the drive for each roller comprises a drive disc 2a, 2b engaging a spherical segment 3a, 3b to rotate the segment about a diametral axis, each segment being coupled to its roller to rotate it. The segments 3a, 3b are connected so as to be simultaneously pivoted about horizontal diametral axes as winding proceeds, so that the disc 2a or 2b associated with the unwinding roller contacts parts of its spherical segment of decreasing radius from the axis of rotation so as to increase the rotational speed of the roller as the material thereon decreases in diameter and thus maintain the web speed constant. Similarly, the disc associated with the winding roller contact parts of its spherical segment of increasing radius so as to decrease the rotational speed of the roller as the material thereon increases in diameter. The pivoting of the segments is controlled by a loaded floating roller 31 which moves upwardly as winding proceeds. The segment 3a has fixed to it a diametral shaft 4a mounted in bearings 6a in a tubular member 5a fixed to another tubular member 7a rotatably mounted in the machine frame. The member 7a carries the shaft of its roller, which shaft is coupled to the shaft 4a by bevel gearing 10a, 11a. The segment 3b is similarly mounted and coupled to its roller. In addition, it carries a toothed segment 40 engage by a worm 41 forming part of a regulator 42 operated by movement of the roller 31 through links 32, 44. A link 43 connects the two segments 3a, 3b so that movement of the roller 31 causes simultaneous movement of both segments.

Filed: 1950-12-29
Abstract: 683,734. Friction lighters. RONSON ART METAL WORKS, Inc. Dec. 29, 1950 [Dec. 30, 1949; Jan. 4, 1950], No. 31572/50. Class 75(iii) In a gas fueled lighter having a burner mounted in, and a cap member mounted on, the top wall of a fuel chamber casing, the cap being movable between positions wherein it either overlies or exposes the burner mouth, a fuel valve mounted in the burner mouth is movable between an inner closed position in which it is held by the cap member in the burner overlying position and an outer open position to which it is moved as the cap member is moved to the burner exposing position, the cap member being spring urged towards the burner overlying position to close the valve. The valve 15 is normally held in the closed position by a cap 6 under the action of a spring 11 pressing on a plunger 10a beneath a finger piece 8. Depression of the finger piece 8 raises cap 6 and the valve 15 is then lifted by the pressure of the gas within the fuel chamber 2. The gas passes from the chamber 2 to the burner mouth through a porous metal or ceramic plug 25, through passages formed between a plug 23 and a bore 22 of an annular member 21 and the lower face of a member 18, and through passages 19 and 5. Since the flame height at the burner mouth fluctuates with temperature, the pressure of the gas passing to the burner mouth is controlled by making the plug 23 of a synthetic nylon-type material having a coefficient of expansion about ten times greater than the brass or similar material of the valve body 3 and member 21 so that, as the lighter heats up, the area of the gas passage between the end of member 23 and the face of member 18 is altered. In the arrangement shown in Fig. 3 a spring loaded ball 115 prevents valve 122 opening upon slight movement of the cap 106.

Abstract: 359,420. Electromagnetic switches. WEST & CO., Ltd., A., Lewes Road, Brighton, and BREEZE, V., Nestor, The Avenue, Kingston, near Lewes, Sussex. July 21, 1930, No. 31930/29. [Class 38 (v).] The armature of an electromagnetic contactor is secured to its carrier in such a manner that it has a limited amount of universal motion thereon to enable it to align itself with the pole faces of the relatively fixed magnet, the carrier itself having a similar mounting upon its pivoting support. As shown in Fig. 2 the carrier 5 is mounted loosely upon its pivot pin 13 and normally rests against the stop 8. It carries contact fingers 7 brought into engagement with corresponding fixed contacts on attraction of the armature 3 to the pole faces of the core 1 due to energization of the coil 2. The armature 3 as shown in Fig. 3 consists of two sets of laminations 3a secured between an inner plate 9 and an outer pair of plates 10. The armature is mounted at its centre of gravity on a pin 12 secured between the two flanges of the carrier 5 the hole for the pin 12 in the inner plate being a relatively close fit and the holes in the outer plates a relatively loose fit. Thus the armature on attraction has a limited universal motion to enable it to align itself with the pole faces of the magnet 1, this alignment being further assisted by the loose pivotal mounting of the armature carrier. Two air gaps 14 are formed in the core 1 to prevent residual magnetism. To prevent distortion of the core 1 during mounting, the magnet 1 is mounted in position in the manner described in Specification 347,751, the side-plates 4 between which its laminations are secured being pivoted about the axis X on the pin 13 and also pivoted universally about a point Y.

A method of severing a work-piece 3 by means of a rotary cutting tool, such as a saw 2 or an abrasive disc, comprises rotating the work and tool relatively to each other about an axis lying parallel to the tool axis and passing through the point 1 of first contact of the tool and work so that the cuts made in the work have a wedge-shape as shown at 12, the depth of cut at the point 1 being zero and gradually increasing towards the end of the cut in order to avoid impact loads on the cutting points as they enter the material to be cut. The saw 2 may be moved about the point 1 in the opposite sense to its rotation so that its centre describes the arc 13 or the work 3 may be moved relative to the stationary saw in the same sense as the saw rotation. When cutting tubular work, the work is pivoted about the point 1 until the saw cuts through to the internal diameter and then the work is rotated about its own axis to complete the cut round the annulus. The workholder 8 shown in Fig. 3 has a pair of parallel bores 10 in which the work-pieces 3 are held by screws indicated at 11 and it is transversely adjustable to accommodate different diameters of saw.
