Title: Improved machine for shaping pneumatic tyre casings
IPC: B29D30/36
Filed: 1931-03-04
Abstract: 370,593. Moulding tyre covers. GOODYEAR TIRE & RUBBER CO., 1144, East Market Street, Akron, Ohio, U.S.A. March 4, 1931, No. 6726. Convention date, April 9, 1930. [Class 87 (ii).] A machine for manufacturing tyre casings from the " flat," of the kind in which the band is shaped and the air-bag inserted automatically in a single process, is fitted with special driving- gear for the air-bag piston and the top plate of the shaping mechanism. In operation the band 114 is placed between top and bottom plates 146, 112 respectively and is expanded into tyre form by fluid pressure introduced into the interior of the chamber thus formed. The bag 90 is drawn first into a cylinder 56 by the downward movement of the piston 66 and afterwards is pushed into the expanded band on the return stroke. The piston is reciprocated by a lever 54 on an oscillating shaft 48 which is driven by a crank 46 connected by a link to a crank pin 38 on the gear wheel 28 driven from the motor 14. Similar gearing acting through the pivoted arm 122 raises and lowers the crosshead 134 carrying the top plate 146. The machine is fitted with electrical control. When the piston 66 and the upper plate 146 are both at the upper ends of their strokes, a bag is engaged with the sliding hook 76 which is advanced by hand for this purpose. Starting the motor then causes the arm 54 to depress the piston and carry the bag downwards into the position shown in full lines in Fig. 1. Near the lower end of the stroke the latch 106 reaches the cylinder floor and also is released from the member 68 by the fixed cam 110, so that the finishing movement of the piston retracts the hook 76 by lowering the pivot 96 relatively to the pivot 102, thus operating the arm 92 projecting through the hook. During these movements the upper plate 146 has also been lowered into the position marked B, Fig. 1, and at this stage automatic cam mechanism stops the motor. The tyre band 114 then is placed in position on the bottom plate 112 and the motor restarted. The plate 146 thus is lowered to form an airtight closure with the top of the band. At this stage cam mechanism opens a valve to admit pressure fluid to the interior of the cylinder 56 to shape the band, the upper plate continuing its downward movement during the process. The arm 54 meanwhile has been moving the piston upwards so that the released bag is deflected by guides 154 into alignment with the band and is enabled to follow closely the shaping of the casing. When the bag is completely in register with the completelyformed casing the motor is slowed automatically for a short time and the pressure in the casing then released. The motor then is accelerated until the upper plate and piston have been retracted so that the tyre and bag can be removed for vulcanization.

Title: Improvements relating to the production of ferrous sulphate monohydrate by evaporation of acid liquors
IPC: C01G49/14
Filed: 1953-03-16
Abstract: Ferrous sulphate monohydrate is obtained from an aqueous solution of ferrous sulphate containing free acid, e.g. iron pickling liquor, by spraying the solution in a current of hot gas, the temperature of the solution being kept below the boiling point of the free acid.  The hot gas can be obtained by combustion of gas or oil; or waste gases from a boiler house or an annealing furnace may be used.  The gas preferably enters the spray evaporator at a temperature of 300-350 DEG C., and leaves at 105-110 DEG C.  The process is carried out in a tower walled or clad with acid-resistant bricks.  The solution is sprayed through jets into the top of the tower.  Hot combustion gases from a furnace build in front of the tower are blown into the liquid mist, and flow down the tower with the droplets.  It is readily possible to adjust the temperature and quantity of the heating gas so that a slurry of monohydrate in aqueous acid is obtained at the base of the tower.  It is also possible to restrict evaporation to such an extent that precipitation does not take place in the tower, but only subsequently in a collecting vessel by addition of concentrated acid with simultaneous cooling.

Filed: 1975-02-21
Abstract: 1500366 Force measuring device R P DUNNE 21 Feb 1975 [22 Feb 1974] 7371/75 Heading G1G A force measuring device comprises a filament or beam vibrated at a particular frequency by an excitation force, output means for detecting the period of the vibration, which output means has its output modified from a first value to a corrected value to compensate for those changes in the length of the filament or beam which result from the application to the filament or beam of the force to be measured. As described the vibrating filament pre-tensioning force is low and, under application of the force to be measured, the vibration signal (or multiple or submultiple thereof) is available measured at 1 and fed to sample/reset control logic 2. Counter 4 measures the number of reference clockpulses from 3 occuring between output pulses from 2, to produce an output number representing the period of the vibrating filament. This value is stored at 5 and is squared to produce an output 1/f<SP>2</SP> where f is filament frequency, at 6. Store 7 stores a number K which represents a constant of proportionality calculated iteratively or obtained experimentally and relates the filament length to the amount of pre-tensioning load thereon.: It is stated that: where W 1  is the load on the filament to be measured plus the pre-tensioning load. Subtractor 8 produces the denominator of the above expression and the output of inverter 9 is a number representing W 1 . The value of the pre-tensioning load is stored at 10 and subtracted from W 1  in subtractor 11, to produce an output representing the load to be measured the value of which is adjusted in multiplier 13 by a scaling or "spanning" factor fed from store 12. The scaled value is then processed/ indicated/or recorded at 14. It is stated that the present invention produces an accuracy of measurement of two decimal magnitudes better than prior art. The measured load may act with or oppose the pre-tensioned load which may be tensile or compressive.
