Title: Improvements in or relating to the manufacture of molded tyre inner tubes
IPC: B29D23/24
Filed: 1929-12-04
Abstract: 346,380. Moulding plant for wheel tyres. FIRESTONE TYRE & RUBBER CO., Ltd., (formerly FIRESTONE TYRE & RUBBER CO. (1922), Ltd.), Gt. West Road, Brentford, Middlesex.- (Firestone Tire & Rubber Co. ; Akron, Ohio, U.S.A.) Dec. 4, 1929, No. 37180. [Class 87 (ii.).] A method of making moulded tyre inner tubes comprises forming tubing from a continuous stream of rubber, forming the tubing in lengths, inserting valves and splicing the lengths in endless form, all said operations being performed while the work passes along a substantially straight path, the spliced tubes being vulcanized along a second path which may be straight or L-shaped. A conveyer 10 deposits batches of rubber in the bin 12 from which they are transferred to a warming mill 13. From here the rubber is led in a continuous strip to the tuber 15 by the conveyer 14. The rubber is extruded as tubing 16 which is conveyed through water-spray cooling devices 18, 19, and dried by an air ring 21. Another conveyer carries the tubing over the weigher 23 to the measurer 24 which marks it off in fixed lengths. Having been cut off the tube pieces have their ends opened and the soapstone dusting powder removed bv compressed air in the blow-out hood 25. The tubes then pass to the valve-patch stitcher 26, the valve-inserting machine 27, and a buffing-machine 28 where the ends of the tubes are buffed. An operator splices the ends together on the machine 29 and places the endless tubes on platforms 31 of the L-shaped conveyer 32. The tubes are removed from the conveyer 32 by operators for vulcanizing in the units 33 and are then replaced and conveyed to the valve-assembling table 35. The tubes are then taken away for testing. Reference has been directed by the Comptroller to Specification 257,914, [Class 87 (ii), Moulding plastic &c. substances].

Title: Improvements in or relating to methods of and means for controlling the printing units of a perforated card operated tabulating machine
Filed: 1930-12-10
Abstract: 368,766. Statistical-apparatus ; calculating-apparatus. BROUGHAM, L. E., Brillig, Riddlesdown Avenue, Purley, Surrey. Dec. 10, 1930, No. 37278. [Class 106 (i).] A method of and means for controlling the adding and printing units of a record-card controlled statistical machine consists in connecting the setting mechanism of each unit to a cross-total unit whereby each item sensed is set up in all the units, the cards being additionally perforated to cause selective non- printing in those units to which the entry does not relate. The apparatus comprises essentially a sensing mechanism with an extension pin box having a plurality of sets of extension rods with cross connections to corresponding rods of each set. The invention is described as applied to a tabulating machine with type sectors and controlling means as described in Specifications 26896/13, 108,942, [both in Class 106 (i), Calculating &c.], and 365,689. The machine comprises four totalizing units A .. D, Fig. 1, for the totals and the items relating, say, to costs, material, and labour respectively. The rods A<1> .. D<1> are interconnected by cross-bars 2 and the rods C<1> are extended to co-operate with the pins of the sensing pin box (not shown). To ensure that an item shall be entered only in the appropriate unit and in the total unit A each unit B, C, D is provided with eliminator bars B<2>, C<2>, D<2> having extensions B<3>, C3, D3 cooperating with certain sensing pins. The control arrangement of perforations is shown in Fig. 2. As regards the top row of perforations the eliminators B, C will be actuated to raise the nought shutters as described in Specification 365,220 whereby printing in their respective units is prevented. Manual settable means comprising stops B<4>, C<4>, D<4> co-operating with projections B<5>, C<5>, D<5> on the eliminator extensions are provided to hold the bars raised to prevent printing in any column. If the rods of the several units are extended to co-operate with sets of sensing pins all the items may be punched on the same cards in different fields. In such a case the card feed must be regulated so that the card is sensed as many times as there are items punched thereon. The card feed may be controlled by a quadrant and a cam lever as described in Specification 271,935, [Class 106 (i), Calculating &c.].

Abstract: 921,880. Analogue-to-digital converters. VYZUMNY USTAV OBRABECICH STROJU A OBRABENI PRAHA. Nov. 1, 1960 [Nov. 2, 1959], No. 37580/60. Class 40 (1). The angular position of a system of shafts coupled together through 10:1 1 reduction gearing is converted into digital form by selecting one out of a group of ten leads provided for each shaft, by means of movable contacts which co-operate with ten fixed contacts. Two movable contacts are provided for each shaft except the least significant, one or the other of these contacts, which are spaced apart by half a digit division, being selected in accordance with the position of the preceding shaft by means of diode gates 0<SP>11</SP>-4<SP>11</SP> and 5<SP>11</SP>-9<SP>11</SP>, Fig. 4, in order to prevent errors when a transition 0-9 or 9-0 takes place. Contacts 0-9 are respectively connected to indicator lamps 0<SP>1</SP>-9<SP>1</SP> and, for example, to a machinetool control system operated in accordance with instructions set by a record card or tape or multiposition switch P. Zero offset may be obtained by a switch A, provided for each decimal denomination, which is arranged to cyclically exchange the connections between fixed contacts 0-9 and lamps 0<SP>1</SP>-9<SP>1</SP>, for example, by connecting contact 0 to 1<SP>1</SP>, contact 1 to 2<SP>1</SP> and so on. At the same time, since the exchange of connections is equivalent to a rotation of the input shaft, switch A is arranged to select two out of a number of movable contacts 13-18 on the following shaft. The contacts of the pair selected are always spaced by one half digit division, but the actual pair selected depends on the extent of the equivalent rotation of the preceding shaft. Ideally there are ten contacts 13-18. The least significant shaft may drive a simple single-wiper multiposition switch as shown in Fig. 4, or the switching device of Fig. 6 may be used. This device comprises ten discs 10 arranged on a shaft, each disc having ten contact blades 20 arranged in staggered relationship with blades 20 on the other discs. Blades 20 co-operate with ten fixed contacts 30 in such a way that a different contact 30 is opened (or closed) for every 3.6 degrees rotation of the shaft, ten complete scans of the contacts 30 being made for each complete revolution of the shaft.

Abstract: 1,167,436. Moulding configured sheets; laminates. W. R. GRACE & CO. 21 Aug., 1967 [19 Aug. 1966], No. 38363/67. Headings B5A and B5N. [Also in Division B6] A thermoplastic sheet for use in a dielectric moulding or embossing process has a dielectric loss factor which decreases from one face to the other. Consequently the face having the higher factor is heated more rapidly than the rest of the sheet and the time taken to raise this face to the softening temperature is less than when the temperature of the whole sheet is raised uniformly. The sheet may consist of a single-layer containing a non-uniformly dispersed conductive or dielectric additive (see Fig. 1, not shown) or may comprise a plurality of layers each having a uniform dispersion of additive, the amount of additive decreasing from one layer to the next (see Figures 2, 3 and 4, not shown). The first of the above types of sheet may be made by coating or extruding P.V.C. containing a uniformly dispersed additive such as carbon black and subjecting the sheet, whilst still fluent, to a vibrating or electric field through one surface, and the second of the above types may be made by laminating preformed layers or by successive casting and gelling in a mould. This latter process is used to give a sheet having an upper layer of carbon containing P.V.C., a middle layer of carbonless P.V.C., and a lower layer of P.V.C. containing finely-divided sand. Such sheets are moulded or embossed by locating them together with a configured die between the plates of a conventional dielectric press, vacuum being applied to the sheets to enhance the flow of material into the configured die. In the preferred embodiment, the plates are moved towards each other to form a vacuum seal after which movement is continued until the plates just contact the sheet. Dielectric heating is then applied for a short interval after which the plates are further forwarded to effect the moulding or embossing.
