Abstract: 431,264. Spring supports for handlebars and saddles. PARTRIDGE, J., 61, Kenninghall Road, Clapton, London. Jan. 1, 1934, No. 35131/33. [Class 136 (iii)] In a resilient mounting for the handle-bars and saddles of cycles, the part supported is fixedly mounted at one end of a bifurcated lever, or a pair of levers, pivoted to a pillar forming part of or mounted upon the cycle frame, and one or more springs are interposed between a supporting element upon the pillar and the bifurcated lever or pair of levers at the other end or at a position remote from the part supported, in such a way that the controlling force exerted by the springs is applied symmetrically to the lever at both sides of the pillar. In the form of handle-bar mounting shown in Fig. 1, the stem a is provided at its upper end with a fitting b having a transverse boss formed with apertures into which are screwed pivot pins e, on which are mounted the forked arms c<1> of a bell-crank lever c, c<3> provided with a clamp c<2> for the handle-bar d. The short parallel arms c<3> of the bell-crank lever are pivoted at f to a stirrup f fitted with a compression spring h, which abuts against a projection a<1> on the stem a and is adapted to be adjusted by means of a screwed rod g and nut g<1>. The inclination of the lever c is adjusted by means of a curved plate i, Fig. 4, fitting against the transverse boss of the member b and having projections i<1> engaging arcuate recesses c<4> in the edges of the pivotal portions of the arms c<1>. The plate is slotted at i<2> for the passage of studs i<3> which screw into the transverse boss.

Title: Improvements in or relating to the production of cellulose solutions
IPC: D01F2/00
Filed: 1929-11-18
Abstract: 345,613. Cellulose solutions. DEUTSCHE GOLD-UND SILBERSCHEIDEANSTALT VORM. ROESSLER, 7, Weissfrauenstrasse, Frankfort-on-Main, Germany. Nov. 18, 1929, No. 35254. Convention date, Nov. 26, 1928. [Class 2 (ii).] Cellulose xanthates; ammoniacal-copper cellulose solutions; preparatory treatment of cellulose.- Cellulose solutions, for example viscose or ammoniacal copper cellulose solutions of very high viscosity are prepared by completely removing oxygen from the starting material and the solvent and by carrying out the entire process of solution under absolute exclusion of air, the action of active light being avoided as much as possible; further, solutions of definite viscosity are obtained by introducing exactly measured quantities of oxygen into the mixture &c. solution. Oxygen is removed from the starting material by adding oxygenabsorbing agents such as an ammoniacal solution of cuprous oxide or cuprous chloride, or by boiling with water with or without the addition of oxygenabsorbing agents and with or without the application of a vacuum. Removal of oxygen from the solvent is effected by adding oxygen-absorbing agents ; and from the container by flushing with oxygen-free inert gases. In an example, raw cotton, linters, &c. is mixed with copper hydroxide and cuprous oxide and dissolved in ammonia, oxygen being excluded by oxygen-free nitrogen. After determining the viscosity, definite additions of oxygen in the form of ammonium persulphate are added to mixtures similarly prepared and the corresponding viscosities determined. By plotting a viscosity curve, the requisite addition of oxygen for a particular viscosity is readily determined. In a second example, a 2 per cent xanthogenate solution is prepared by treating 2 parts of sulphite cellulose with 1 part pyrogallol and 18 parts 18 per cent caustic soda, maturing for three days, adding the requisite quantity of carbon bisulphide and filling up with water, all operations being effected in an atmosphere of oxygen-free nitrogen. The viscosity may be increased by first boiling the cellulose with water under vacuum. The Specification as open to inspection under Sect. 91 (3) (a) gives further examples of the preparation of ammoniacal copper cellulose and viscose solutions of particular viscosities by omitting some of the precautions to exclude oxygen. This subjectmatter does not appear in the Specification as .accepted.

Apparatus for the production of printing plates from thermoplastic material comprises an embossing press having heated upper and lower platens 3, 2, a cooling press having a lower platen 4 level with that of the embossing press and an upper platen 5 movable by a fluidoperated piston 13 acting on an eccentric shaft 9, and conveyer means for moving a printing plate between presses. A piece of thermoplastic material 18 and a matrix 17 are placed in superimposed relationship on the platen 2 and the platen 3 which is operated by hydraulic or toggle means is moved down so as to press the matrix into the thermoplastic material. The platen 3 is subsequently raised and the assembly of matrix and printing plate is moved quickly on to the platen 4 by means of endless chains 23 mounted on wheels 25, 26 and carrying dogs 24 which engage a supporting plate 39 for the assembly 17, 18. The chains 23 are actuated by a hand-crank 28 and the dogs 24 are disengaged from the plate 39 as soon as the assembly is correctly positioned on the platen 4. The platens 4, 5 are cooled and the upper platen 5 is connected to the eccentric shaft 9 by connecting rods 6. A lever 11 secured to the shaft 9 is connected by a link 12 to the piston 13 which is slidable in a cylinder 14. When compressed air is introduced into the bottom of the cylinder 14 the shaft 9 is rotated and the platen 5 moves downwards to bear on the matrix and plate assembly 17a, 18a while it is being cooled. When compressed air is released from the cylinder 14 the piston 13 descends under its own weight and raises the platen 5. The rods 6 are pivotally connected to the platen 5 by eccentric bearings 19 which can be rotated by a handle 20 so as to vary the width of the opening between the upper and lower platens. Before being put in the embossing press the matrix and thermoplastic material are preheated under slight pressure between heated platens 21, 22, of which the upper platen is pivotally secured to the lower. When an assembly 17b, 18b of matrix and material is positioned on the platen 21 the platen 22 is swung down into engagement therewith by hand, pressure being applied by means of co-operating hooks 29, 30 mounted on the platen 22 and a shaft 32 respectively. The shaft 32 is eccentrically mounted and is rotatable by means of a pneumatic piston and cylinder arrangement 36, 37 whereby the hooks 30 are first moved into engagement with the hooks 29 and then pull downwards on the latter hooks.

[Also in Division D1] A fabric length or a garment part or garment is composed of a series of rib knitted portions connected by a draw thread and a separating course such that the length of the fabric, garment or garment part can be reduced as desired merely by withdrawing a particular draw thread and separating course and leaving the edge of the remainder with a selvedge or welt. The rib structure of the fabric can be utilized to ensure that each portion of the fabric after the draw thread, is formed as a selvedge or welt and this can be achieved by knitting on the needles of both beds of a rib machine separately during the knitting of the separating course and draw thread such that the appearance of the fabric on the front face is maintained without distinction. Alternatively the knitting may impart a definite stripe appearance which may be enhanced by colour distinction. The fabric may be of float stitch construction in a repeating course sequence and the draw thread and separating course thread are knitted to ensure that one appears on one face and the other on the other face of the fabric. The fabric may be formed round the bottom of a knitted frock, skirt or jumper, or round the bottom of a sleeve, to facilitate shortening.
