Patent GB-229534-A (GB)
Title: Automatic electric generating system
IPC: H02J3/38
Filed: 1924-05-13
Abstract: 229,534. Carpenter, H. F. May 13, 1924. Lighting-systems; systems of charging and discharging galvanic batteries; starting primemovers.-An automatic electric generating system comprising a prime-mover A, generator B and storage battery D has the battery connected to the generator through solenoids F, G, which operate a rocking member 20 to start the primemover A, using the machine B as a motor, upon the occurence of a heavy load in a load circuit E, or after a certain interval on the occurrence of a light load therein. The prime-mover is stopped only after the cessation of the load and the diminution of the charging current to a predetermined value. A heavy load in the circuit E energizes the solenoid F to rock the member 20 into contact with a contact 30, thereby completing a circuit from the positive of switch H through a coil 28 of a controller 15 and through a switch 34 to the negative lead 13. Movement of the controller 15 opens the earth lead of the engine ignition circuit at the contacts 38, and connects the machine B to run as a motor and start the primemover A. The prime-mover continues to run as long as the combined action of the solenoids F, G is sufficient to maintain closed the contacts 20, 30. Movement of the controller 15 also causes a switch 41 to insert a resistance 42 in series with the coil 28 and thereby reduce the " holding-on " current. A light load in the circuit E rocks the member 20 insufficiently to contact with the member 30, but sufficient to close a switch 44 and complete a circuit through a heater 47 of a thermal switch 50, which, if the load in the circuit E persists, eventually closes, and completes a circuit in shunt to the contacts 20, 30 thereby starting the prime mover as in the case of a heavy load. The prime-mover can also be started by throwing a switch 32 on to its contact 63, thereby completing a shunt to the contacts 20, 30. Should the prime-mover fail to start, the heavy current taken by the machine B and passing through a coil 17 neutralizes the effect of a coil 60 and keeps a switch 48 closed thereby completing a circuit through the coil 54 and slowly raising the plunger 56 of a dash-pot device the plunger eventually tripping the switch 34 and opening the circuit through the coil 28. The switch 34 can only be closed by hand.

Title: Improvements in or relating to the production of adsorbent cuprene
IPC: C08F10/00
Filed: 1933-04-22
Abstract: In the manufacture of cuprene by the catalytic polymerization of acetylene at a raised temperature, the catalyst is promoted with a small proportion of stannic oxide.  The properties of the product vary with the temperature employed.  Thus, with a contact mass comprising cupric oxide and stannic oxide in the proportion 99 : 1, a reaction temperature of 250--260 DEG  C. yields a hard brittle variety of cuprene, while a temperature of 180--245 DEG  C. yields a soft flocculent variety; the latter is obtainable in two forms, one being produced at 180--200 DEG  C. and the other at 230--245 DEG  C. All the forms of cuprene produced have absorptive properties, and the form produced at 180--200 C. is particularly suitable as an adsorbent for use in respirators.ALSO:In the manufacture of cuprene by the catalytic polymerization of acetylene at a raised temperature, the catalyst is promoted with a small proportion of stannic oxide.  The acetylene may be diluted with a small proportion of nitrogen or other inert gas, and the reaction may be effected at a slightly raised pressure. The properties of the product vary with the temperature employed. Thus, with a contact mass comprising cupric oxide and stannic oxide in the proportion 99 : 1, a reaction temperature of 250--260 DEG  C. yields a hard brittle variety of cuprene, while a temperature of 180--245 DEG  C. yields a soft flocculent variety; the latter is obtainable in two forms, one being produced at 180--200 DEG C. and the other at 230--245 DEG  C.  All the forms of cuprene produced have absorptive properties, and the form produced at 180--200 DEG  C. is particularly suitable as an adsorbent for use in respirators.  An example is given in which a mixture of cupric oxide with 4 per cent of stannic oxide is made into a slurry with water and brushed over iron trays; the latter are placed in a reaction vessel, which is heated electrically to 180--190 DEG  C. and flushed with nitrogen until all the air has been displaced, whereafter acetylene is introduced.

Filed: 1963-03-26
Abstract: 1,036,472. Continuous casting-machines. HUNTER ENGINEERING CO. March 26, 1963, No. 11849/63. Heading B3F. In a continuous casting machine in which metal is cast in sheet form onto a moving belt overlying a cooled platen, the belt is of a woven glass cloth the interstices and surface irregularities of which cause it to frictionally adhere to the metal when it solidifies so that the cloth contracts in width with the metal. Aluminium is cast through a nozzle 40 into the gap between endless driven fibreglass belts 10 each backed by a watercooled platen 5, 16, warping of said platens being prevented by heaters 56. The top belt assembly is pivoted for movement by an adjusting screw 23, Fig. 1. Edge members 29 for confining the metal extend between the belts and are carried by an endless driven chain 28, guided by a guide bar 30 having a cam surface so that the edge members follow the edges of the metal as it shrinks transversely together with the casting cloth. The chain and edge members assemblies are mounted on brackets 24, Fig. 3, so that they may be swung about vertical axes to expose the edges of the belt. In order that the contracted cloth, after detachment from the cast metal may be stretched to its initial width, shallow grooves are provided in the guide bars 18, 19 at the entrance to the belt gap, the grooves being directed helically in a right and left direction from the centre, to exert a lateral wiping force on the belts 10. The cast metal is continuously extracted by a unit 45 comprising rolls 47 and edge rolls 48.
