Title: Improvements in or relating to the magnetisation of permanent magnet systems
IPC: H02K49/04
Filed: 1958-01-31
Abstract: 854,190. Magnetizing and demagnetizing; electromagnetic couplings and brakes; switching systems for magnets. BAERMANN, M. Jan. 31, 1958 [Feb. 1, 1957], No. 3347/58. Classes 35 and 38 (4). The degree of magnetization of a permanent magnet system, e.g. for an eddy current clutch or brake is adjusted by suitably controlled current impulses. As shown for an eddycurrent brake with axial air-gap 14, the permanent magnets 11 are mounted on a magnetic or non-magnetic support 12 facing the magnetic eddy-current rotor 16. In the case of a clutch the support 12 is rotatable. The machine may alternatively be of cylindrical type. The control coils 20 are energized with current impulses from a source 21 shown in detail in Fig. 3. The impulses are derived from an adjustable condenser bank 35, charged from a battery 30 and discharged through a gas-filled triode 34, and change-over switch 37 leading to the series or parallel connected field coils 20. The triode is caused to discharge by means of a switch 40 or by adjusting the grid voltage applied from a battery 41. By opening switch 36 and closing 44 or 45 the discharge may be passed through a resistor 42 or choke 43 which may have a movable iron core. By closing switch 47 or using two triodes connected back-to-back, the choke 43 may be used to produce a damped oscillation for complete demagnetization. The coils 20 may be selectively energized, and may be fed with a steady direct current of smaller magnitude to augment the maximum natural flux of the magnets or for fine control. The coils 20 may be of aluminium.

Title: Improvements relating to controlling devices for apparatus dispensing measured quantities of liquids
IPC: B67D7/10
Filed: 1936-05-04
Abstract: 479,513. Dispensing liquid fuel etc.; controlling sales. KERRY, J. O., and KERRY, G. F. May 4, 1936, No. 3412. [Class 116] Apparatus for controlling the sale of measured quantities of petrol or other liquids includes a cash register whose keys are so connected in electric circuits that when a key corresponding to the particular quantity or value of the liquid to be dispensed is depressed the indicators are zeroized and the pump circuits cleared for a fresh delivery operation. On receiving an order for liquid, an attendant sets an order indicator 2 to the figure corresponding to the specified quantity, this operation causing a solenoid 4 to actuate a remote register 5 step-by-step by means of a pawl 6, the circuit through the solenoid being completed through the nozzle of the delivery hose (not shown) bridging the contacts 20, 21. The rotation of the register shaft 7 carries a contact arm 8 on to a split ring 11 whereby a circuit through a mercury switch 13 and a solenoid 23 is prepared for completion. The rotation of the register shaft 7 also sets a contact arm 15 to bridge appropriate contacts in the register, corresponding to the quantity to be delivered, and thus prepares a selected circuit for completion by the corresponding key of a cash register 19. The attendant then closes a switch 60 to start the pump motor, whereupon the required quantity of liquid is delivered into a gravity tank (not shown). The nozzle is then removed from the contacts 20, 21 to discharge the measured quantity of liquid from the gravity tank to the consumer's container, the removal of the nozzle allowing the contact 20 to move automatically on to the contact 22 thereby energizing the solenoid 23 and tilting the mercury switch 24 to break the circuit through the pump motor. When the key on the cash register, corresponding to the transaction, is depressed, a circuit is completed to energize a solenoid 29 to tilt the mercury switch 24 to prepare the circuit through the pump motor ready for closing by the switch 60, the mercury switch 13 being simultaneously tilted by a solenoid 28 to open the circuit through the solenoid 23 and also to release the pawl 27, whereupon the register shaft 7 returns to zero position as by the action of a cord and hanging weight. The apparatus is thereby prepared for a fresh dispensing operation. A signal lamp 33 may be fitted to indicate that the apparatus has been thus prepared. To limit the number of keys on the cash register, keys 18 may be provided to indicate full gallons, a single key 39 to indicate one half-gallon only, and a single key 40 to indicate any half-gallon in excess of a unit. A counter may be fitted to indicate the sum of all movements of the arm 2.
