Title: Process for preparing tubeless pneumatic tires for use and structure by which the process may be utilized
IPC: B60C25/18
Filed: 1968-09-19
Abstract: A process for assembling a tubeless pneumatic tyre on a wheel rim includes the steps of mounting the tyre on the rim, the latter having a valve-stem-receiving opening with air-tight obstruction means blocking the opening, filling the tyre with air without disturbing the obstruction means, and engaging the obstruction means with an end of a valve stem to unblock the opening, and mounting the valve stem in the opening without permitting the escape of a substantial amount of air. The obstruction means may consist of a rubber grommet 12, Fig. 1, closed by a diaphragm portion 16 and having a groove 14 to engage the opening in the wheel rim. A brass or rigid plastics insert 18 has an internal thread 22 to receive a threaded projection 38 on the valve 34 after the latter has pierced the diaphragm 16. A skirt 36 clamps the upper end of the grommet against the insert when the valve is screwed home. The valve may have a projection 86 of a different shape as shown in Fig. 5 to pierce a diaphragm extending across the grommet below the insert 72. In place of the grommet, a thin metal disc 122, Fig. 9, may be adhesived or soldered to the rim 120 which is pierced by an extension on the valve, the extension having a slot 130 to form abrupt edges and corners. A rubber plug 144, Fig. 11, which is dislodged by a projection 148 during assembly of the valve or a rubber cup fitted within the boss 142 and pierced by a pin on the valve may be used. A rubber cap may also be used to enclose an inwardly projecting boss or a plug 204, Fig. 17, with a conical indentation 206 may be inserted in an opening 202 in the rim to be dislodged by a projection 208 on the valve 210. An 0-ring abuts a shoulder 216 to form a seal.

Title: Hydrocracking process
IPC: C10G65/10
Filed: 1969-06-23
Abstract: In the production of motor gasoline and jet fuel a heavy hydrocarbon oil is hydrocracked in a first stage at 600-850 F. and 200- 10,000 p.s.i.g. using a catalyst of 2-10 wt. per cent Ni and 5-30 wt. per cent W as the sulphides on a support which contains 15-60 wt. per cent of a zeolite Y, modified by ion exchange to reduce its alkali metal content to less than 5 wt. per cent, and at least one of the amorphous metal oxides silica, alumina, silicaalumina, magnesia, zirconia and beryllia. The effluent from the first stage is separated into a hydrogen rich stream which can be recycled to the first stage after removal of H 2 S and NH 3 , and a liquid portion from which a gasoline fraction is removed and the remainder passed to the second stage. A heavy hydrocarbon fraction boiling above 850 F., if present, can be recycled to the first stage or removed from the system. In the second stage, hydrocracking is carried out at 600-700 F. using a catalyst comprising 0À2-5 wt. per cent Pt or Pd on a support such as silica-alumina or the same as that used in the first stage. The effluent from the second stage is separated into a hydrogen rich gas, which is recycled to the second stage or to the first stage, a liquid which is fractionated to provide a gasoline fraction, a jet fuel fraction and a heavier fraction which is recycled to the first stage if more gasoline is required or to the second stage if more jet fuel is required. Suitable charge stocks to the first stage are straight run gas oil, catalytically cracked cycle gas oil, atmospheric residuum, shale oil, tar sand oil, and delayed coker gas oil and can contain 100-500 p.p.m. nitrogen.

Title: Furnace installation operated by direct electrical heating according to the resistance principle in particular for preparation of silicon carbide
IPC: H05B3/60
Filed: 1974-12-20
Abstract: In a furnace installation for producing silicon carbide in an intermittent operation, carbon electrodes arranged in the bottom of the furnace. A horizontally arranged resistance core is electrically connected to the carbon electrodes by vertically extending elements of an electrically conductive material having a higher specific conductivity than the core material. The resistivity of the connection between the electrodes and the core and the current passing through the connection produces a temperature lower than that necessary to form silicon carbide, and thereby prevents the destruction of the connections and electrodes normally caused by the downward movement of the silicon carbide roller.
