Title: Improvements in and relating to Glands or Fairleads and the like used in Aerostats, or other Vessels Made to Contain Gas, Air, or any Liquid.
Inventor: LORD HAROLD
IPC: B64B1/64
Filed: 1917-11-08
Abstract: 120,603. Lord, H. Nov. S, 1917. Aerostats.-A gland or fairlead for an aerostat or other gas or liquid container to permit the passage through the envelope of a pressure-tube or a control-cord, comprises two co-operating members which clamp the material of the envelope between them and carry one or more flexible disks through which the cord or tube passes. Fig. 1 shows two annular members 1, 4 with stepped surfaces clamped over the edges of a balloon envelope 5 by a nut 6. Two rubber disks 8, 9 adapted to form a fluid-tight joint with the control-cord 12 of a valve or ripping panel, or with a flanged tube 17, Fig. 2, are secured against the member 1 by a nut 10. Cords 13 secured to corks 14 wedged through holes in a flange on the nut 6 normally hold the cord in position but become disengaged when the cord is pulled. The flexible disks allow the cord or tube to pass at any angle within the limits shown by dotted lines.

Title: Improvements in automatic maximum-current switches
IPC: H01H75/06
Filed: 1921-06-14
Abstract: 164,755. Siemens - Schuckertwerke Ges. June 15, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Automatic circuit-breakers.-Maximum current switches for heavy currents are provided with resistances shunting the main contacts so that when the main circuit is broken, on overload, a sufficient current still passes through the shunt circuit, if the full overload persists, to retain the switch in the open position and prevent its closure either by hand or electromagnetically. In the hand-operated form shown in Fig. 1, the contact member 2 under the action of the spring 4 is maintained in engagement with the contact 1 by the pawl 5, which forms part of the armature 7, engaging with a nose 6 on the pivot part of the contact member. The load current passes through the winding 10 of the electromagnet 9 and, in the event of overload, the armature is attracted and the contact-member released. A shunt circuit through the winding 10 is maintained by way of the shunt resistance 11, and, if the overload persists, the reduced current in the winding is still adequate to hold the armature. Meanwhile, in the opening movement a nose 12 engages behind a spring pawl 13 on an extension of the armature and positively prevents the return of the contact member until the armature is released on removal of the overload. In the form shown in Fig. 2, in which the switch is closed by means of the electromagnet 16, 17 acting through links 15, 14 the local closing circuit includes fixed contacts 21 which are engaged by a bridging contact 22 on the armature only when the armature is in the unattracted position so that the local closing circuit can be closed only when the armature is not attracted, that is, when no overload exists. In this form, the electromagnet has a separate maintaining winding 25 in series with the resistance 11, enabling a smaller maintaining current to be used.

Abstract: 863,131. Automatic voltage control systems. STANDARD TELEPHONES & CABLES Ltd. May 15, 1959 [May 22, 1958], No. 16427/58. Class 38 (4). In an automatic voltage control system the impedance of a transductor TDRM, controlling the current through a rectifier RM to a load, is varied by a winding CM energized through transductors TDR1, TDR2 in parallel. A signal, dependent on the load voltage, through a winding VC varies the impedance of the transductor TDR1 so as to cause a current to flow in the winding CM tending to maintain the load voltage constant. The load current is limited by a signal, dependent on the load current, through a winding CC causing the transductor TDR2 to present a low impedance across transductor TDR1 at a predetermined current. The transductors are biased by reference windings RFC1, RFC2, RFCM. Specification 665,335 is referred to.

[Class 80 (iii)] A member 3, Fig. 4, is normally locked against rotation in either direction by means of balls or rollers 8 which are wedged by springs 12 between cam surfaces on the member 3 and a drum 4 which is capable of rotation but which is normally maintained stationary, but the member 3 is adapted to be driven in either direction by driving dogs 1 which engage with play in recesses in the member 3, the dogs, during their initial movement to take up the play, displacing the adjacent balls from locking position. The drum 4 is normally maintained stationary by means of a brake or, as shown, by being formed as a worm wheel gearing with a worm 14 and constituting an irreversible gear. In the first case, the member 3 can drive the dogs and the drum on release of the brake, while in the second case the drum can be rotated, and with it the member 3 and the dogs, by turning the worm 14, as by a handle 15. Antifriction balls or rollers may be interposed between the dogs and the balls 8. The Specification as open to inspection under Sect. 91 comprises also the following arrangements. As shown in Fig 6. (Cancelled), an activating lever L journalled on a fixed shaft A has a dog P engaging with play in a recess in an actuated arm B, the latter being normally looked against rotation in either direction by spring-urged balls 21 wedging between the shaft A and cam surfaces in the arm B. Pins 23 projecting from the lever L act to unlock the arm B during movement of lever L. The pins 23 may be tapered, as shown in Fig. 8 (Cancelled), and a spring 27 be interposed between the lever L and arm B, the dog P then engaging without play in its recess. In this case, lever L is first moved axially towards arm B, so as to unwedge the balls 21, and is then turned to actuate the arm. As shown in Fig. 9 (Cancelled), an actuated member O slidable on a fixed shaft X is normally locked to the shaft by spring-urged wedging balls 31, but is adapted to be moved by an actuating member N which, during its movement, first unlocks the member O through a ball race C or D. This subject-matter does not appear in the Specification as accepted.
