Title: Electric battery chargers
IPC: H02J7/00
Filed: 1971-12-17
Abstract: 1356480 Battery charging systems STAPLES & SON Ltd 7 Nov 1972 [17 Dec 1971] 58704/71 Heading H2H  Battery charging apparatus comprising a thermally operated switching device is provided with means to prevent damage to the apparatus should a battery be incorrectly connected to the apparatus. A battery to be charged is connected to the output terminals 7, 8 so as to be charged from an A.C. source by way of a transformer 1, rectifier 4 and a thermally operated switch 6. When a battery is connected to the terminals 7, 8 with the correct polarity a current flows from the battery through a circuit comprising the bi-metal element 10 of the switch 6, a resistor 12 and a diode 11. The blade 10 heats up and deflects from the terminal C to the terminal B whereupon the battery receives charging current. Should the battery be connected incorrectly no current flows in the circuit 10, 12, 11 and the switch 6 remains unoperated. As the battery charges, the charging current falls until, when the battery reaches a predetermined charge the element 10 is insufficiently heated whereupon it returns to contact C. The battery then discharges heavily through resistor 12 and diode 11, reheating element 10 which deflects to contact B. Thus the battery remains fully charged by alternate charge and discharge steps. A lamp 13 indicates that the battery is correctly connected and a lamp 14, incorrect connection. The lamp 13 will also indicate a fully charged battery by pulses of light. Alternatively a meter 9 may be used for indicating purposes. In other embodiments the thermally operated switch 6 is placed in an auxiliary circuit and is arranged to control the charging current by way of an electromagnetic relay or a further thermally operated switch, the charging current circuit being divided into two parallel paths.

Title: Locking devices
IPC: B60R25/021
Filed: 1971-12-23
Abstract: 1403867 Locks WILMOT-BREEDEN LTD 20 Dec 1972 [23 Dec 1971] 60179/71 Heading E2A [Also in Division B7] A key operated anti theft device comprises a spring loaded bolt and a separately spring- loaded bolt-carrier, in each case spring loaded towards the locking position and key-operable means comprising a cam which acts on and moves the bolt carrier to withdraw the bolt, the bolt carrier being movable independently towards the locking position of movement of the bolt is impeded so that it does not engage fully to the locking position with the mechanical part to be locked. A body 1 having a split portion for engaging a vehicle steering column houses the slidable bolt 5 urged by a spring 12 to operative position and slidable in a slot in the bolt carrier 9 urged by springs 13 (Fig 5 not shown) to the operative position. Since the carrier 9 can move to the operative position independently of the bolt 3 if, when the bolt is projected, it is not aligned with the locking recess in the steering column it engages the recess when the steering column is turned. The body houses a cylinder lock 6 which is connected by a shaft 8 to a rotatable switch mechanism 7. The shaft 8 extends through the bolt carrier 9 and supports a cam 16 which engages the bolt carrier to withdraw the bolt when the key is turned from the Lock to Ignition position. The tip of the key abuts a projection 17a on a lever 17 which normally pivots on the cylinder lock 6 and the cam 16, the lever having cam shafts which engage in bores in the cam 16 and in a member 22 by which the lock is coupled to the shaft 8. The lever also has a projection 17b and is urged by a torsion spring to abut a spring urged plunger 25 or the bolt carrier, the lever being retained in abutting position by the tip of the key engaging the projection 17e so preventing the bolt from moving to locking position. To lock the steering column the key is moved to the lock position and then withdrawn thus freeing the lever 17 to pivot under the force of the bolt carrier which under spring-pressure slides past the projection 17b and moves the bolt to locking position. To withdraw the bolt the key is moved to Ignition position and the cam engages the bolt carrier and retracts the plunger 25 to allow the bolt carrier to move past the lever projection 17b thus releasing the bolt from the steering column recess. The plunger 25 contacts a contact 31 which may be connected to an indicating circuit. The engagement of the plunger with the projection 17b prevents lock picking as does the lever by preventing direct access to the bolt carrier by a wire inserted in the key way.

Title: Switching mechanisms
IPC: D06F58/38
Filed: 1971-12-29
Abstract: 1413796 Machinery safety devices HOTPOINT Ltd 20 Dec 1972 [29 Dec 1971] 60619/71 Heading F2J [Also in Divisions F4 and Hl] A switching mechanism including a member 2 manually rotatable from an "OFF" position to one or more angular positions to cause operation of switches 7 for energizing an electric motor arranged to drive a rotatable drum of, for example, a tumbler dryer, the member 2 being arranged to govern directly or indirectly (i.e. by timing mechanism or by temperatureresponsive means) the duration of energization of said motor, has spring means 14 which is arranged to apply torque to the member 2 to return it quickly to the "OFF" position but is normally restrained by latch 15, 16 which is released when a door giving access to the drum is opened. As shown, rotation of knob 5 winds a clockwork timer motor 4 and, by pin 13 engaging a lug 12, turns a disc 10 and winds a spiral return spring 14. The disc 10 has steps 11 around its periphery and latch tongue 16 engages a selected step to restrain spring 14 while motor 4 is allowed to drive spindle 2 slowly back to its original "OFF" position-by virtue of the lost motion between pin 13 and lug 12. However, should the drum door be opened the Bowden cable 19 ensures release of latch tongue 16 from the step 11 and spring 14 overrides motor 4 and rapidly restores spindle 2 and switches 7 to "OFF". In the embodiment of Figs. 5 and 6 (not shown) the timer motor and lost-motion coupling are omitted, disc 10 is replaced by a disc (68) having progressively deeper steps, and the latch tongue (72) is controlled by a bellows (75) connected by capillary (74) to a temperature sensing phial (73); thus the device is restored to the "OFF" position at a temperature predetermined by the step selected, or immediately if the drum door is opened since the latch (72) is then moved by the Bowden cable (79) an amount greater than the largest step. Another embodiment (Figs. 3 and 4, not shown) combines both time and temperature controls by using a disc (36) to determine the temperature at which the motor (24) commences a time drive to the spindle (22) and a lost-motion disc (30) to restrain the rapid return safety spring (34). A heating element may be controlled by one of the switches of the device which then provides the extra safety feature of preventing inadvertent energization of the heater by closure of the door, since the device must be reset before operation of the dryer is resumed.
