Title: Improvements relating to door-operating and like mechanism
IPC: E05F15/10
Filed: 1945-06-12
Abstract: 593,175. Door-operating mechanism. GENERAL MOTORS CORPORATION. June 12, 1945, No. 14848. Convention date, July 19, 1944. [Classes 44 and 65 (i)] [Also in Group XXXVII] Door-operating mechanism comprises a latch-held spring forming part of a telescopic link, and a motor-operated screw and nut device, the nut of which is adapted to move in one direction to release the spring and effect a quick movement of the door and to move in the return direction and effect a slow reverse movement of the door. A tubular member 60 while telescoping within a casing 81 stresses a coil spring 78 which is held in the stressed condition by a spring- loaded pivoted latch 71 engaging the outer race of a ball bearing 50 mounted on a screw shaft 25. A recess 64 in the link pivotally engages a lug mounted on a bomb-bay door of an aircraft. A nut 52 having a bevelled portion 73 which in the closed position of the door as shown, abuts the latch, is adapted to slide within the link, the nut and shaft co-operating by means of travelling balls 53 which are contained within a channel defined by coincident helical grooves. An electric motor 20, pivotally connected to the fuselage of the aircraft by an apertured lug 21, is adapted to rotate the shaft through a magnetic clutch which drives a spindle 23, on an eccentric portion 40 of which is rotatably mounted a hypocylic gear member 43 having two sets of teeth which mesh respectively with internal teeth on gears 28 and 32. The former is secured to the screw-shaft and the latter is held stationary by the meshing of external teeth with a worm 35. The gear 28 has a flange 100 formed with a worm tooth which meshes with a gear 101 coupled by a train of reduction gearing to a switch control cam. To open the door a selector switch is moved to the " down " position, closing circuits for operating the motor to move the nut downwards, thereby tripping the latch and releasing the spring which projects the link out of the casing, a collar 61 on the link then resting on an upper flange 152 of the nut. The cam operates switches arranged to stop the motor after the latch is tripped. When the door is fully open a signal lamp becomes illuminated. The selector switch when moved to the " up " position closes further circuits which energize a reversing field winding in the motor. The nut then ascends carrying with it the link until the latch becomes re-engaged. The cam is arranged to reverse the direction of rotation of the motor at this point, causing the nut to descend until it abuts the latch, when the motor is stopped by the cam. A second signal lamp then becomes illuminated to indicate that the door is fully closed.

Preferably a neon tube 63 indicates which mode has been selected and whether the flash supply capacitor 56 is fully charged. The tube 63 is visible in the view-finder and is also externally visible via a prism (37), Fig. 3 (not shown). In the embodiment described, the same aperture is set in modes (a) and (b). As shown, (a) in the first position, shown in Fig. 6A, a diaphragm opening 7 is operative, switch contacts A and B are bridged to disconnect battery 54 and switch contacts A' and B' are bridged to short out indicator tube 63 (b) in the second position of the switch 1, the switch slider 19 is moved to the right. Diaphragm opening 7 is still operative, but contacts B and C are bridged to connect in battery 54 and contacts B' and C' are bridged to connect in tube 63. When capacitor 56 is charged tube 63 is turned on (c) in the third position of the switch 1, the slider 19 is moved further to the right. This pivots the diaphragm vane 6 out of the exposure path to provide a larger exposure aperture. Contacts C and D are bridged to connect in battery 54 and contacts C' and D' are bridged to connect a capacitor 64 in parallel with tube 63. When capacitor 56 is charged, capacitor 64 repeatedly charges through a resistor 62 and discharges through tube 63, causing tube 63 to flash.

Title: Improvements in and relating to telephone receivers, loud speaking telephones and the like apparatus
IPC: H04R7/22
Filed: 1925-06-08
Abstract: 253,357. British Thomson-Houston Co., Ltd., Hutt, J., and Bird, G. H. June 8, 1925. Earpieces and attachments ; diaphragms.-The diaphragm of an acoustic device is clamped against the edge of the casing by means which is fitted into or under the instrument cover and arranged to be a press-fit on the outside of the casing. Fig. 1 shows a diaphragm 11 clamped against the end of the casing 12 by an annular lid device 13, the depending rim of which is a close fit against the outside of the casing 12. The depending flange 15 of the cover 14 is arranged to be a tight fit against the co-operating part of the member 13. In the modification, Fig. 2, the flange 15 of the cover 14 rests against an outwardly extending flange 16 on the member 13, the middle portion of which is raised at 17 and terminates in an annular upstanding flange 18 arranged to lie against the co-operating flange 19 on the cover 14. In a further modification, the end of the flange 16 is curled round the end of the flange 15 and the end of the flange 19 is curled round the inner portion of the member 13. Fig. 4 shows a further construction in which the member 13 is initially in the form of a cylinder having V-shaped notches in its upper edge and cuts in its bottom edges, the tongues thus formed at the top end being pressed over flat on to the outer side of the diaphragm as at 25, whilst the material between each pair of cuts in the bottom end is alternately opened up as at 23 against the inner side of the diaphragm 11. leaving a number of tongues 24 to engage against the outside of the casing 12. Instead of forming cuts in the bottom edge of the cylinder, the lower edge thereof may be left intact, incisions being made in the cylinder to form tongues to be pressed flat against the inner side of the diaphragm. A setscrew or pin may be used to prevent accidental displacement of the cover, whilst, in the case of head-attachment gear, the ends of the stirrup may be taken through holes in the rim of the cap into recesses in the side of the casing. The Provisional Specification describes constructions in which the diaphragm is of somewhat larger diameter than the casing or the projecting edge of the diaphragm is rolled over the edge of the casing into a lateral groove therein, or a laterally rounded flange is provided externally on the mouth of the casing and the edge of the diaphragm rolled or pressed over it. In either case the diaphragm may be applied hot so that on contraction it will be taut and firm.

So that movable contact 3 is held without chatter against the fixed contact even while spring contact member 1 is vibrating, contact 3 is mounted on a spring tongue 2 flexed outwards from member 1. So that the space occupied by a contact spring assembly may be little increased by the distance contact 3 is flexed from member 1 in the contact open position, operating member 8 presses tongue 2 against member 1 as it moves the latter against its own tension into the contact-open position. Member 8 moves away from the tongue in the contact-closed position, so that the anti-bounce characteristic of tongue 2 may be effective. Two contacts 3 may be mounted on halves of a split tongue 2 (Fig. 2, not shown), or the tongue 2 may itself be of contact material, e.g. silver.
