Abstract: 1,184,247. Propelling pencils. PARKER PEN CO. 7 Sept., 1967 [9 Sept., 1966], No. 41003/67. Heading B6P. In a retractable propelling pencil, a continuous lead feed mechanism 27, which is retractable within the barrel 11 of the pencil, comprises a lead storage magazine 29, a lead guide tube 31, a lead advancing mechanism 33, an actuating spring 41 and a collet 35. Axial reciprocation of an eraser assembly 57, removably mounted to the end of the magazine 29, non-rotatably mounted in the barrel 11, causes axial movement of the magazine 29 and guide tube 31 relative to the advancing mechanism 33, thereby causing feeding of a lead. Depressing the eraser assembly 57 also projects the feed mechanism 27 in the barrel 11 against the return bias of a spring 43. The feed mechanism 27 is latched in the projected position by a leaf spring (73, Fig. 2) attached to the magazine 29, engaging a detent (97) on a pivotally mounted pocket clip. The feed mechanism is released from the projected position by pivoting the pocket clip. Whilst in the projected position, the lead feed mechanism 27 can be operated to advance a lead by depressing the eraser assembly 57. This operation does not retract the pencil, but merely moves the leaf spring (73) away from the detent (97), to be returned when the pressure on the eraser assembly is released. In a modification of the project-retract mechanism (Fig. 7), the leaf spring (129) is released from the detent by a radially movable pushbutton (145) mounted in the pocket clip. (Fig. 8) illustrates another form of pivoted pocket clip for releasing the detent mechanism.

Abstract: 1356925 Theft alarms HARPBOROUGH Ltd 20 Aug 1971 [27 Aug 1970] 41194/70 Heading G4N [Also in Division H1] In or for an anti-theft system, a coincidence switch comprises a cylindrical body 10 having at each end a rotatable dial 14, 29 inscribed with letters or numerals, one dial 14 being coupled to a contact plate 17 having a small insulating insert 22 whilst the other dial 29 is coupled to a member 24 carrying a contact pin 26. The coincidence switches are arranged such that the contact pin 26 makes electrical connection to the plate 17 in all positions of the dials 14, 29 except when they are both set to the corresponding positions. As described, the coincidence switch may be mounted on the body X of a road vehicle, dial 14 being on the outside of the vehicle. Dial 14 is mounted on a collar 16 having pins 18, 19 to couple the dial 14 to the metal disc 17 having the insulating insert 22. The contact pin 26 is carried by an insulating disc 24 on a stern 25 rotatable by the inner dial 29. Teeth 30 are engaged by a peg 31 so as to provide positive location for the dial 29. Setting of dial 14 may be facilitated by lamp 32 which becomes connected to contact 34 if the dial 14 is depressed axially. Terminals 21, 27, 35 are provided for the contact peg 17, contact pin 26 and lamp 32. Anti-theft systems.-When the driver leaves the vehicle, he sets dial 14 to any position other than that to which the inner dial 29 has been set, thus closing the circuit (Fig. 4) between contact peg 22 and contact pin 26. If a door or bonnet is opened without resetting the contact switch A, one of contacts 42 ... 44 will close, energizing relay 46 from the vehicle battery or from an auxiliary battery, the relay being held in its energized position by a permanent magnet 50. Contact 47 breaks the ignition circuit 40 whilst contact 48 operates an alarm 49. The magnet 50 ensures that the alarm 49 continues despite reclosing of doors or interference with the coincidence switch A. The alarm may be silenced by a push-button 51.
