Title: Improvements in or relating to locking systems for the doors of motor vehicles
Inventor: HABGOOD GORDON ALFRED
IPC: E05B65/36
Filed: 1960-12-23
Abstract: 963,706. Door locking systems. WILMOT BREEDEN Ltd. Dec. 21, 1961 [Dec. 23, 1960], No. 44248/60. Heading E2A. A locking system for the doors of a motor vehicle comprises a releasable fastening mechanism for each door, a locking member movable between two positions and one of which is a locking position in which it prevents opening of the door by operation of the operating member, and a double acting solenoid having two aligned energizing coils operable to reciprocate an armature member and a key operated lock for at least one door of the vehicle. This lock has an electrical switch operated by the key to complete an electrical circuit on -locking the door. The circuit controls operation of one of the two energizing coils so that, on operating the key to lock the door, the operating members on that door and the other doors cannot be operated to open them. Further circuit means are provided for energizing the other of the two coils of the said solenoids to move the locking members out of the locking portion to enable the doors to be opened by the external operating members. The fastening mechanism, Figs. 1 and 3 on the front door of the vehicle comprises a main shaft 12 mounted on a plate 14, supporting a latch member 10 on one side of the plate 14 and a spring-loaded cam plate 15 on the other. The latch member 10 bears in the closed position, against a keeper 20 mounted on a base 18 supporting a spring-loaded wedge member 21. To close the latch a contactor plate 23 is rotated about its axis 24 e.g. by a push button causing the cam plate 15 to rotate into abutment against a stop 16. To lock the door a key is inserted into a barrel lock 51 to rotate a crank pin 36 which engages in a slot 37 of a flange 34 of a locking lever 31. The lever 31 due to an over-centre spring 37 is urged into a position abutting against an extension 33 of the contactor 23, thus preventing rotation of the cam plate 15 and movement of the latch member 10 out of its closed position. The key is rotated through 90 degrees so that a contact pin 53 engages contacts 55 or 56, which causes a solenoid 40 to be energized and move a pin 39 into locking engagement with a slot 38 in the locking lever 31. The locking mechanism for the rear doors of the vehicle, Fig. 5, is modified in so far that the extension 33 and the key lock are omitted and the pin 41 replaced by a notch 132 engageable by a bell crank 134 to move the lever 131 between the locked and unlocked positions. The solenoid device is operable to lock the latch members in the closed position in both the front and back doors by rotation of a key in the lock of the front door in one direction. The circuit interconnecting the doors is described. The rear doors may be locked from the inside. The doors are unlocked by rotation of the key in an opposite direction.

Abstract: 1,127,924. Oil-filled cables. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 4 Nov., 1965 [4 Nov., 1964], No. 44951/64. Heading H1A. In a method of manufacturing oil-filled sheathed electric cable, a sealing plug is attached to the leading end at least of the cable core, the core is dried, transferred prior to sheathing to an unheated vessel which is then evacuated, and fed from the vessel to be sheathed under vacuum, the sheath also being applied in vacuum-tight manner to the sealing plug or plugs, and oil is admitted through the leading end plug while vacuum is maintained at the other end. As shown the end of hollow conductor 48 bared of insulation 42 is soldered into a recess of plug 24, spigot 46 preventing solder from blocking the duct. Preferably the trailing end of the core also has a sealing plug. The core, wound on a drum is dried in vacuo, the conductor being heated by passage of an electric current. The electrical connections (Fig. 4, not shown) to the end plugs are removed, the drum is transferred to a tank connected to the sheathing press, a towing device (Fig. 7, not shown) is attached to the leading end plug and the core is drawn into a duct between the tank and the sheathing press. The tank is evacuated, the duct being sealed by e.g. an inflated air bag, and the core is drawn through the sheathing press. The plug may have been provided with a layer of low melting point solder to aid adhesion of the sheath, or the sheath may be clamped as shown by means 62. Corrugations 58 improve the vacuum-tightness of the seal, or 0-rings may be used (Figs. 4, 5, not shown). After sheathing and attaching a vacuum connection to the trailing end, oil is admitted through valve 64. The oil may be admitted while sheathing is in progress if the cable is led away from the sheathing apparatus along a path, a portion of which is at a higher level than the pressure head of the oil supply.

Abstract: 1,084,652. Winding yarns continuously doffing packages. E.I. DU PONT DE NEMOURS & CO. Oct. 26, 1965 [Oct. 26, 1964], No. 45261/65. Headings D1D and D1J. A continuous yarn winding apparatus has a bobbin driving roll 22, Fig. 3, over which yarn 26 is traversed before being wound onto a tube pressed against the roll 22 by a first chuck (20) (not shown), there being a second chuck 18 that presses a fresh tube against the driving roll 22 when the first chuck 20 has been moved to a doffing position, characterised in that each chuck 18, 20 has a groove (52), Fig. 2 -(not shown), containing V-shaped snaring elements (54) and angularly disposed severing elements (55), and to ensure that the yarn is caught and severed in said groove at the commencement of a winding operation there is a pivoted frame 56 and bar 60 that are swung by pneumatic means 64 from a lower inoperative position (not shown) to an upper operative position, Fig. 3, so that a rod 110 carried by the frame 56 will cause the yarn 26 to be pressed against the second chuck 18 and thereafter further pneumatic means 58 is operated to move the bar 60 in the direction of traverse in a manner causing a hook 118, Fig. 6 (not shown) on the bar 60 to engage the yarn 26 and traverse it into a setting wherein it is in alignment with the groove (52) Fig. 2, in chuck 18 so that the yarn will be caught up therein. Thereafter the bar 60 traverses back to its original setting and the frame 56 swings downwardly to its inoperative setting. Doffing A timing device determines when the tube on the chuck 18 is full, and links supporting the chuck 18 are then operated to move the package away from the drive roll 22 and deposit the chuck ends on end supports (36); Fig. 1 (not shown) the package having sufficient rotational intertia to continue winding. Further links swing the other chuck (20), with an empty tube thereon, into engagement with the drive roll 22 and the yarn is then taken up by the chuck (20) and tube thereon in the manner described above. As the yarn commences to wind onto the empty tube brake shoes (40), Fig. 1 (not shown), rise to stop the rotation of the completed package. Traverse This is by means of a reciprocating guide 24, Fig. 1 (not shown). Transfer tail The groove (52) lies outside the traverse range of the guide (24). When the yarn has been snared and severed in the groove (52) of the chuck, the yarn passes under a tooth (76), Figs. 4 and 7 (not shown) pivotally mounted on bar 60 and which holds the yarn at the setting of the tooth until there is sufficient tension in the yarn to pivot the latch against the bias of a magnet (82) and so release the yarn to the traversing device (24). As the yarn moves from the latch to the traversing device a transfer tail is formed on the tube on which the package is being wound.
