Title: Improvements in and connected with prepayment mechanisms for the control of the supply of electric energy
IPC: G07F15/06
Filed: 1928-10-12
Abstract: 324,318. British Insulated Cables, Ltd., and Wilson, L. B. Oct. 12, 1928. Electricity, supplying by meter; mechanism for prepayment rent; delivery of electricity otherwise than by meter and time-controlled apparatus.-In a prepayment mechanism for use in the supply of electricity, a remote control device, operable by an external authority, is actuated by a high frequency current to prevent the main switch controlling the supply to the consumer from closing, until a definite fixed charge has been prepaid by the insertion of one or more coins or tokens into the prepayment mechanism. As shown employed in conjunction with an ordinary prepayment meter, the coin for the fixed charge is inserted into a coin barrel 16, Fig. 1, which is turned by a handle 11, the barrel being constructed and operating as desscribed in Specification 285,937. A cam 10 is thereby caused to actuate an arm 13, Fig. 3, to separate contacts 8, 9 on arms 6, 7, the arm 6 being held in open position by a projection 3 on a spring-controlled pivoted armature 2 of a highfrequency relay 1. The arm 6 is connected to the line 28 of the lines 28, 29 on the consumer's side of the prepayment meter 30, the arm 7 being connected to the line 29 through the winding of a magnet 31 and through a main switch 33 to the line 29. The magnet has an armature 32 associated with the switch 33. Lines 26, 27 lead to the source of supply and the relay is connected across the lines 26, 28. The meter 30, actuated by a barrel 21 and handle 22, controls a switch 37, 38 connected in parallel with the switch 8, 9. After a predetermined interval, say a week, the relay is actuated by the supply company to close the contacts 8, 9 thereby energizing the magnet 31 which opens the main switch 33. The switch 33 cannot be closed until a further coin is inserted in the barrel 16 for the fixed charges. The magnet 31 is also energized when the consumption causes the switch 37, 38 to close. The relay 1 and associated parts may be used independently of a metering arrangement. When more than one coin is required for the fixed charges, the cam 10 is actuated from the barrel 16 through a gear train.

Title: Water-soluble reactive azo dyestuffs
IPC: C09B62/006
Filed: 1977-07-13
Abstract: The new reactive dyes have the formula <IMAGE>  where   D is the radical of an aromatic carbocyclic or heterocyclic diazo component,   R is optionally substituted alkyl,   R1 is hydrogen or optionally substituted alkyl,   B is a bridge member or a direct bond, and   X is a reactive group.   These dyes are obtained by combining diazotised amines of the formula D-NH2 with an appropriate coupling component. A further process for preparing the dyes of the formula I where B is a direct bond involves reacting the diazotised amines of the formula D-NH2 with a compound of the formula <IMAGE> to form corresponding dyes, which, by elimination of Y-H, are then reacted with reactive components to introduce the radical X. Starting from the diazotised amine D-NH2 and reacting with a dye of the formula III containing the bridge member B and likewise reacting with a reactive component to introduce X gives the corresponding new dyes. The dyes obtained can be used for dyeing and printing hydroxyl- or amido-containing textile fibres, yarns and fabrics.

Abstract: 896,026. Ventilating buildings. DUNN Ltd., ALEXANDER. Aug. 26, 1960 [Aug. 29, 1959], No. 29544/59. Class 137 [Also in Groups XIII and XXXV] In a heating and ventilating system in which air is circulated through a heater by a fan driven by an electric motor 22, the motor speed is controlled by temperature sensitive thermistors 27 responsive to the air temperature upstream of the heater such that an increase in air temperature results in an increase in fan speed and vice-versa. In the system shown a fan 20 driven by an electric motor 22 causes air to flow through the conduit 23 into air heating passages 12, 13 formed around a fireplace 11. The air outlet from the heater is through a conduit 25 in which is a proportioning control device 26 incorporating a bank of the thermistors 27. When the air temperature increases the resistance of the thermistors decrease, thus increasing the current through the motor and causing more air to flow. The control device 26 may be fitted with a thermostat connected in series with the bank of thermistor elements 27, so that if the fluid temperature falls to a predetermined limit the thermostat opens the switch and-stops the fan motor. The thermistors are supported in the device 26 by insulating mountings 29.
