Patent GB-437002-A (GB)
Title: Improvements in electrically operated temperature regulating mechanisms
IPC: G05D23/275
Filed: 1935-02-04
Abstract: 437,002. Thermostats. VAPOR CAR HEATING CO., Inc., 80, East Jackson Boulevard, Chicago, U.S.A. Feb. 4, 1935, No. 3572. Convention date, Feb. 26, 1934. [Class 64 (ii)] An arrangement for automatically controlling the temperature of air supplied from a fan C to a chamber through a duct B comprises a heater D, a cooler E and a selector switch K by means of which the heater or the cooler may be put in operation, the switch also having contacts to enable one of a number of predetermined temperature settings of the control apparatus to be selected. The temperature is thermostatically controlled by means of thermostats 47, 82, 84, 111, 117, 118, a separate thermostat being provided for each temperature setting. The switch has a central neutral position and anticlockwise movement from this position causes energization of the heater and selection of the appropriate thermostat associated therewith. Similarly clockwise movement causes energization of the cooler which is supplied from a refrigerator G. Linked with the switch K by a lever 41 is a snap action switch LL<1> which snaps over when the neutral position of the switch K is passed to connect the relay P to control the fan motor when the switch K is on the heater contacts, and to connect the relay P to control the refrigerator motor 10 when the switch K is on the cooler contacts. When the switch K is on a heater contact, e.g. as shown, the contacts of the thermostat 47 are connected across the winding 52 of a relay N energized through the bridging contact 13 of the switch K. Closure of the thermostat-contacts short circuits the relay winding 52 which operates to cause the valve 5 on the steam supply to be shut by the energization of a solenoid 67. Movement of the valve lever trips a switch 71 which opens the circuit of solenoid 67 and resets the circuit of solenoid 79 for reverse action when the thermostat contacts open due to fall of temperature. The speed of the fan motor C is controlled by a thermostat M through relays O and P, when the temperature rises the fan speed is increased by a resistance 87 being short circuited. When the switch K is on a cooler contact, e.g. contact 25, the thermostat 111 is placed in series with the winding of relay O and the relay P is connected by the switch L, L<1> to the motor 10. When the thermostat contacts close due to a rise of temperature the relays O and P operate to close the circuit of the motor 10 and start the refrigerator G. When the temperature drops the relays O, P open to stop the motor. An additional contact 27 is provided for running the refrigerator constantly independent of temperature variations.

[Also in Groups IX and XVI] Film winding apparatus comprises a part spool composed of a core with a rim at one end and an annular cheek detachably secured round the rim, the part spool being adapted to be secured on a hub on a take-up spindle, which hub carries a disc forming one flange of the takeup spool so formed, the annular cheek forming the other, the part spool also being adapted, when the film has been wound thereon, to be secured in a rotatable film feed member by means of the annular cheek so that the core can then be detached from the cheek and the film wound from the centre of the coil. In the form shown the annular cheek 12 is secured to a core having an inner bush 7 and a concentric annular part 6 which, however, does not form the whole of the circumference of the take-up spool, a part 5 being secured to the flange 2 on the hub 1 on which the bush 7 slides and is secured by a catch 8. A space is provided between the annulus 6 and the bush 7 which provides anchorage for the film, as shown dotted in Fig. 10. The core assembly carries on its outer end face, members 13 pivoted at 14 (Fig. 9) which can be swung outwardly into the space 16 between two thicknesses of material forming the central portion of the cheek 12, to secure it to the core assembly. After winding, the catch 8 is released and the bush 7, together with the cheek 12 and the wound film still supported on the annulus 6, is transferred to the feed member. This has a flange 23 permanently and rotatably mounted on the fixed spindle 21. The flange carries members 26 which are simultaneously radially adjustable to engage the outside of the film coil as the cheek 12 is moved into position. The core assembly 6, 7 is then disengaged from the cheek 12 by movement of the pivoted members 13. As the flange is pushed finally into position, it is secured by latches at 35 on the cylindrical member 34 on the flange 23 and, at the same time, the core assembly 6, 7 is expelled by engagement with one half 37 of an hyperboloidal core-member fixed to the spindle 21. The other half 41 is then placed in position and secured by the catch 21a. This half carries a film guiding member 39. The take-up spindle assembly is carried on a spindle 4 and driven by a belt on a pulley 17 thereon. The feed member is driven from this spindle by chain 19 and sprockets 18, 20. The ratio of this drive may be unity or may differ therefrom slightly to take account of small differences between the inside diameter of the feed coil and the outside diameter of the take-up coil.
