Title: Improvements in and connected with distance control mechanism for use with weighing apparatus
IPC: G01G23/36
Filed: 1937-07-06
Abstract: 495,493. Weighing-apparatus. AVERY, Ltd., W. & T., and PROSSER, T. W. July 6, 1937, No. 18707. [Class 143] In a remote-control mechanism for association with weighing-apparatus operable in conjunction with a traversable load receiving means, the weighing-apparatus incorporates an electrically driven automatic weight totalizing and recording mechanism and the traversable load receiving means is caused, when brought into the correct weighing position, to complete a section of a circuit through a constant speed motor which determines the performance of a prescribed sequence of operations which involves the starting of the automatic weighing, totalizing and recording mechanism, the completion of the circuit being effected by means under the control of a carman which means can only become operative when the load is in its correct weighing position. The invention is described in connection with a furnace coke charger. When the coke charger car is correctly positioned on the weighbridge a shoe on the car operates a double spring- controlled contact switch a, a<1>, opening the section a' and closing the section a. The sections a and a<1> of the switch are located respectively in the circuits of a constant speed motor b and the car-driving motor (not shown). The circuits through the constant speed motor b and through the motor c of a steelyard weighing - apparatus include a push - button switch d controlled by the carman. Provided the switch section a is closed by the presence of the car, closure of the push-button switch energizes a solenoid e causing operation of contactor switches e<1>, e<2>, e<3>, e<5> to start up the constant speed motor b and permit the weighing and recording motor c to be started up and accelerated through a known type of accelerator contact starter e<6>. The constant speed motor is connected by reduction gearing to a slotted contact-controlling drum f and to a cam-shaft. One pair of cams, operating on switches m controls the circuit of a magnet h<3> which, when energized, liberates the steelyard and permits a weighing operation to take place. On completion of the weighing operation, a second pair of cams closes a pair of contacts m controlling a magnet p, switches p<1>, p<2> and a magnet p<3>. The energization of the magnet p<3> effects the printing of the weight on a tape and rings a bell q to inform the carman. The short arm of the steelyard in assuming equilibrium position closes a switch n to permit energization of the car driving motor and allow the car to be driven away. As the car leaves the weighbridge, the switch a, a<1> returns to normal position and the constant speed motor b is stopped by the action of the slotted drum f. Specifications 4935/05, 13544/06, 15690/09; and 103,707, [all in Class 143], are referred to.
Patent GB-990840-A (GB)
Title: Light refractory brick
IPC: C04B38/06
Filed: 1963-05-13
Abstract: A cellular refractory body is produced by mixing a refractory powder of particle size less than 100 microns and a binder with spheroidal polystyrene beads 0.01-0.3 inch in diameter, to coat the beads; forming into shape while maintaining pores between the beads; and firing to remove the beads; giving a structure having 70-97% porosity.  Exemplified refractory powders are alumina, zirconia, silicon carbide, and silicon nitride (formed in situ from silicon by firing in a nitrogen atmosphere). The shape is formed under vibration or light pressure in a mould, and is dried prior to firing.  Firing temperatures of 1750 DEG  and 1800 DEG  C., may be used if the refractory powder is finely ground. Porosity is said to be due to hollows left by the beads (of diameter 0.01-0.25 inch), to pores left between the beads, and to small pores in the walls.
