Title: Improvements relating to electric time switches
IPC: G04C23/12
Filed: 1920-03-16
Abstract: 141,682. Fabrik Elektr. Apparate F. Sauter. April 15, 1919, [Convention date]. Winding-apparatus, electric.-An electric time switch comprises a spring-driven clock element which, at predetermined time intervals, connects in circuit an electric motor which actuates the contact elements of the time switch and also automatically winds up the driving-spring of the clock movement. The winding of the spring barrel is effected through a coupling which remains connected to a transmission wheel until the spring has been fully wound, each operation of the electric motor being designed to wind the spring to an extent exceeding the running down of the spring. The spring drum 1 drives a gear 2 which operates, through a clock mechanism and time disk, a relay time switch 3. An electric motor 6 is arranged to drive a switch spindle 15 and an intermediate spindle 25, and is controlled by the relay switch contacts 12, 13 and a commutator 8 on the switch spindle 15. This commutator has two brushes 10, 11 co-operating with the conducting part of the commutator 8 (which is always in connexion with one terminal of the motor) and with insulating segments 9, Fig. 2. The time switch controls a circuit through contacts 16 mounted on the spindle 15. The spring drum 1 is wound through a coupling consisting of a flanged collar 26, keyed to the intermediate spindle 21, having a dog 28 which may engage a dog 29 on a transmission wheel 22 loose on the shaft 21 and in mesh with a wheel 1<a> on the spring drum. The coupling is controlled by a spring 27 and a pivoted lever 30, the free end of which is held in engagement with the end of a pinion 23 in mesh with the wheel 1<a>. The pinion 23 is mounted on a screwed spindle 24 which is driven by the clock mechanism through a spur wheel 25. Whilst the motor is operating it will thus wind the spring drum 1 simultaneously with the turning of the switch spindle 15; it will be stopped by the commutator 8 as soon as the necessary movement of the spindle 15 to operate the time switch 16 has been effected, but the arrangment is designed to wind the spring drum during this time to an extent exceeding the running down of the spring. The coupling 28, 29 will, however, automatically disengage as soon as the wind exceeds the running down owing to the operation of the lever 30 through the pinion 23.

Title: Improvements in and relating to devices for delivering gaseous media
IPC: F04D17/16
Filed: 1970-02-19
Abstract: 1,249,093. Centrifugal blowers. WEBASTOWERK, G.m.b.H. Feb.19, 1970 [April 21, 1969], No. 8042/70. Heading F1C. [Also in Division F4] A device for delivering gaseous media comprises a reversible electric motor 11 driving a blower wheel 12 providing a unidirectional delivery irrespective of the direction rotation, but adapted to provide different outputs according to the direction of rotation, and an annular delivery duct 26 communicating with the blower wheel outlet and extending coaxially with the electric motor. Air supplied by the blower wheel 12 through the duct 26 is heated by combustion gases flowing through a coaxial duct 28 from a combustion chamber 27. Fuel and air for the combustion are supplied by a fuel pump 14 and an air blower wheel 13 driven by the motor 11. The pump 14 delivers the fuel to a rotary atomizer 16. When the heater is to be shut down, it is cooled off by the blower wheels 12, 13. For this purpose, the permanent magnet motor 11 is reversed by means of a polarityreversal switch 18 which also brings a thermal switch 23 into circuit. The blower wheels 12, 13, which are designed for the normal direction of rotation, produce a reduced output during the reversed running, while the reversed delivery of the fuel pump 14 is stopped by a check valve 25. When the heater has cooled off sufficiently the thermal switch 23 stops the motor 11. The combustion air blower wheel may be driven by a separate motor which is not reversed during the cooling-off period, both motors being-stopped by a single thermal switch. The check valve 25 may be omitted, the fuel pump or its driving means then being such that delivery does not occur on reversal of rotation.
