Title: Improvements in or relating to method of and apparatus for making tires
IPC: B29D30/06
Filed: 1927-06-16
Abstract: 285,359. Goodrich Co., B. F., (Assignees of Gammeter, J. R.). Feb. 14, 1927, [Convention date]. Moulding wheel tyres. - In the moulding of tyres, the tyre after building, is distended by forcing into it a plastic mixture containing a fluid, and the mixture is then stiffened by removing the fluid therefrom. A segmental annular core consisting of a hollow perforated metal skeleton 14 on which are moulded outer parts 15 of porous material such as plaster of paris, and held together by an encircling chain 25 in a groove 24 is mounted on an expansible spider, and a tyre is built thereon. The tyre and core are removed from the spider, a flexible bead closing ring 34 centred by means of projections fitting into a groove 16 in the core, and provided with an inlet 33 for the plastic material, is inserted, and the whole is enclosed in a mould 31, 32. A stack of moulds is built up in a press, and the inlets 33 are connected by flexible couplings 39 with a manifold 41, the outlet nozzles 40 of which are preferably set at an angle of 45‹. The manifold 41 is connected with a cylinder 48 with ram 49 on the head of the press, containing the plastic material for forcing into the tyre. This material suitably consists of 100 parts of clay plasticized with 40-50 parts of water, to which may be added 1 or 2 parts of water-glass. On closing the press, the ram 49 is operated to force the plastic material into the tyres. The material flows round circumferential grooves 37, Fig. 6, in the bead closing ring 34, driving the enclosed air through a valve 42, Fig. 5, which allows the air to pass, but closes when the material reaches it. The material flows between the core and the tyre, distending the latter in the mould. The pressure forces the liquid from the plastic composition, which becomes stiffer, while the liquid is absorbed by the porous core 15 which obviates the possibility of penetration of the inner plies of the tyre by water when they become plastic during vulcanization. In a modification, the core has no metal skeleton, but consists entirely of porous material. Specification 272,252 is referred to.

Patent GB-458085-A (GB)
Title: Method of producing highly ohmic resistances
IPC: H01B1/24
Filed: 1935-06-11
Abstract: <PICT:0458085/III/1> High ohmic resistances are obtained by depositing a layer of carbon on to an insulating support from a gaseous hydrocarbon at a pressure which is considerably above the dissociation equilibrium pressure of the hydrocarbon at the particular operating temperature, so that the hydrocarbon is not dissociated immediately and completely, but the carbonizing process is extended over a period of several minutes.  This mode of operation also facilitates the even heating of the supports.  For continuous operation, a series of supports are passed through an inclined tubular furnace 1 or a U-shaped rail 2, their rate of travel being controlled by passage through a pair of driven rollers 4.  Air is expelled from the furnace and a suitable hydrocarbon introduced through inlet 10.  The supports are introduced into the furnace by a set of slotted discs, the uppermost one withdrawing the supports from a magazine 7.  They are then transferred through the lowest disc to the rail 2 by rotation of the middle disc.  A pump is preferably provided to prevent ingress of air.  A similar arrangement enables the coated supports to be withdrawn.  The rotated discs and the rollers 4 are preferably driven synchronously.  Cooling sleeves 11 are provided above and below the furnace proper.  The values of the resistances are varied by means of temperature and rate of passage through the furnace. According to an example, benzol vapour is used at temperatures from 850--1000 DEG  C. and pressures of 20--100 mm., preferably 50--80 mm. of mercury.  Reference has been directed by the Comptroller to Specification 399,967.

In the construction shown each linear part extends parallel to the edge portion of its tape and the end fitting members are formed and secured to their respective tapes by an injection moulding process, the bottom portion of each tape being reinforced at the same time by portions 12 integral with the end fitting members. In this form the rows of elements are of meander kind. In an alternative construction each linear part extends parallel to the respective tape edge but a reinforcing strip is wrapped around the bottom portion of the tape over the linear part and adhesively secured to the tape with heat and pressure if necessary and the end fitting member which can be either of metal or plastics material is secured to the reinforcing strip. In a modification each linear part 11 extends at an angle to the edge of its tape within the reinforcing strip. Coil type elements can be substituted for meander type and in each case the stitching which is used to secure the rows to the tapes act as beads which help to key the end fitting members to their respective tapes. The rows of fastener elements can be made from a fastener element chain which has a linear portion interposed at intervals between series of interlocking elements the linear portion being utilised as the part 11.
