Title: Improvements in or relating to compositions for covering surfaces of roads and the like, and for the manufacture of paving blocks
IPC: C08J3/03
Filed: 1931-07-11
Abstract: Rubber compositions for covering the surfaces of roads and the like and for the road surface of paving blocks, comprise rubber crumb in admixture with a relatively highly concentrated artificial aqueous dispersion of coagulated rubber or the like preferably having a concentration of above 65 per cent total solids.  Known fillers such as carbon black, and whiting may be added, but the composition is preferably free from cement.  The dispersions preferably contain a high proportion of protective colloid such as ammonium oleate or soft soap.  Small amounts of natural aqueous dispersions of rubber may be added.  The artificial aqueous dispersions may be prepared by methods described in Specifications 296,685, [Class 81 (i), Disinfecting &c.], 313,027, and 313,028, [both in Class 70, Indiarubber &c.]. The compositions can be applied to a suitable under surface in dispersed, flocculated, or semi-coagulated condition, or as a paste, and then consolidated by drying or hot or cold rolling. When one or more layers are applied these may vary in composition, such that the lower layers are harder.  The intermediate layers may consist of other materials than the above compositions, e.g. 28,5 parts of 65 per cent rubber reclaim dispersion, 14,3 parts of 60 per cent latex, 7,2 parts soft soap, and 50 parts of cement.  In the production of rubber surfaced paving blocks, concrete &c. blocks are placed in moulds and the composition of rubber crumb and artificial aqueous dispersion of rubber is applied to the top.

S., c /o Dunlop Rubber Co., Ltd., Fort Dunlop, Birmingham. July 13, 1934, No. 20557. [Class 144 (i)] In a machine comprising spring-pressed spinning-discs for consolidating tyre-components on a rotary building- drum, the pressure is automatically adjusted at a given position in the traverse of the spinners by altering the angularity of the springs. In the apparatus shown, the spinners 1 are carried on rocker - arms 2 adjustably pivoted on the cross-stay 13 of a saddle 4, the inner ends of the arms being connected by links 33 to sleeves 22 which, with sleeves 21, form telescopic housings for the springs 6. The free ends of the sleeves 21 are pivoted to a lug 18 on a slide 7 which engages a guide 17 formed in the saddle 4. A bolt 19 threaded through the lug 18 into abutment with the stay 13 serves to adjust the initial angularity of the springs. The latter are moved to position the arms 2 for the commencement of the spinning operation by a piston and cylinder 41, 40 pivotally connected to the sleeves 22. The saddle 4 and its components are power-operated towards the building-drum, and at a predetermined position during this movement a lug 39 on the slide 7 abuts an adjustable stop 35. The further travel of the saddle 14 alters the angularity of the spring-housings on the slide 7, with consequential increase in the spring- pressure of the spinner-arms. The device is stated to be applicable to tyre - building apparatus of the kind described in Specifications 440,994, 438,741, and 441,616.

Title: Method and apparatus for drawing sheet glass
IPC: C03B17/06
Filed: 1921-08-03
Abstract: 191,097. Marks, E. C. R., (Libbey-Owens Sheet Glass Co.). Aug. 3, 1921. Drawing. - Relates to a method of drawing glass in flat sheets and consists in causing the molten glass to flow directly, and in a continuous and unimpeded manner, from the main supply over the surface of a slab to form a shallow pool of substantially uniform depth or thickness, and subjecting the glass from the pool, as it flows from the discharge end of the slab and while it. is unsupported, to a drawing stress to stretch the glass to a uniform predetermined thickness. The glass is melted in a tank 10 and flows through a cooling tank 11 to the drawing chamber 12, its temperature being regulated by arches 18, 23, a flue 20, dampers 21, 85, burners 22, and water coolers 28. The bottom of the drawing chamber is formed by a tile 13 on which the glass collects in a shallow pool, and having a free lateral outlet at its forward end from which the glass is drawn away in a sheet. The tile 13 is supported on walls 37 which form a chamber 38, heated by burners 39. for maintaining the temperature of the pool of glass on the tile. The drawing mechanism comprises drawing rolls 101 and edge rolls 120. This mechanism is placed in such a position that the well 101 is at a distance from the lip of the tile 13 which is sufficient for the sheet to draw to the desired thickness and to have acquired a glaze, so that when it makes contact with the roll its surface is not marred. In a modification, shown in Fig. 10, the glass runs from a tank 166 over a tile 170 and down an inclined slab 173 having a rounded nose 176 from which the sheet 185 is drawn. The slab is preferably of nichrome steel and forms the top of a heating-chamber 180 by which the temperature is regulated. A watercooler 188 assists in regulating the temperature of the glass. The sheet is drawn away horizontally by any suitable mechanism, the distance of the first rolls 186 from the slab being adjusted as before to allow the sheet to stretch and to cool sufficiently to avoid marring.

Class 120(ii) [Also in Group VIII] A top drawing roller assembly for drawing heads of spinning machines comprises a stationary axle having end-journals, an anti-friction bearing secured by its inner race to each of said journals, a thin-walled sleeve adapted to be mounted on and demounted from each bearing, a covering immovably secured on the outer surface of each sleeve to form an integral sleeve-and-covering structure, means to hold the sleeve on its associated bearing, yieldable against inward radial pressure provided by the resilience of the sleeve and/or cover, permitting the mounting and demounting of the sleeve-and-cover structure relative to its bearing in its proper means adapted to locate each such structure on to and from its bearing, and stop operating position. As shown, Fig. 1, a metallic sleeve 6 closed at one end and carrying an elastic covering 7 of cloth, leather, cork, rubber or synthetic material is slidably mounted at each end of an axle 2 on an anti-friction bearing 4 the inner race of which is rigidly mounted on a journal 3 of the axle. Sleeve 6 is slotted at 5 to leave resilient webs 8 which are pressed inwardly by the resilience of the covering 7 to grip the outer race of the bearing. Lugs 9 on the sleeve engage the bearing to locate the sleeve, and a disc 10 shrunk on axle 2 closes the open end of the sleeve. In another embodiment, Fig. 3, members 12 projecting through slots 11 in sleeve 6 are pressed inwardly by the covering 7 to provide stops on the side of the bearing opposite to lugs 14, but are resiliently yieldable to permit removal of the sleeve from the bearing. In other embodiments similar locking members provide stops for both sides of the bearing; or tongues formed by slitting the sleeve wall are bent over at the end and pressed by the covering 7 and by their own resilience into an annular groove in the outer surface of the bearing. In further embodiments, the sleeve is retained on the bearing by the resilient grip of inwardiy cambered webs formed by slitting the sleeve wall, or of bulges formed in the sleeve; in these latter constructions, the covering need not be elastic. In all constructions some canting movement of the roller relative to the axle is provided for either by play in the bearing (e.g. using a single race ball-bearing) or by means of a clearance between the sleeve and the bearing.
