Title: Improvements in or relating to vibrating interrupter systems
IPC: H02M7/62
Filed: 1944-05-05
Abstract: 600,243. Converting. STEVENS, A. H. (Electronic Laboratories, Inc.). May 5, 1944, No. 8557. [Class 38 (ii)] The driving magnet 18 of a vibratory interrupter is energized not only by unidirection current from a D.C. source 10 but also by alternating current induced by the alternate energization of the windings 12 and 13 of a transformer 14. In the form shown, this alternate energization induces in a winding 21 in series with the magnet 18 a current that alternately assists and opposes the D.C. current. The effect is to reduce current consumption for the driving magnet, and to demagnetize the magnet rapidly each cycle. In modifications, the induced A.C. is obtained from a tapping on the transformer secondary or from an additional winding, and the rest position of the reed 15 is in engagement with the contact 17. Specification 555,229 is referred to.

Title: Radio location system
IPC: G01S19/29
Filed: 1946-03-22
Abstract: 607,020. Radiolocation. STANDARD TELEPHONES & CABLES, Ltd. March 22, 1946, No. 8929. Convention date, Dec. 27, 1944. [Class 40 (vii)] In a pulse radar system, the echo from a particular object is selected by a gating circuit and its signal-to-noise ratio is increased, the resultant signal being then combined with the original signal train and applied to a cathoderay tube so that the selected echo may be observed together with all other received signals; by this means the presence of echoes weaker than the selected echo may be detected. As shown in Fig. 1, the transmitter synchronizing pulse is applied to a multivibrator 11 and the pulse derived from the trailing edge of the adjustable - width square - wave output by differentiation at 12 is selected and shaped at 13 and applied to unblock the gate valve 4 to which all the received signals are applied. The selected echo is limited at 5 by clipping the noise and echo peak, Fig. 2e (not shown), and the resultant pulse is amplified at 6 and recombined in the mixer 7 with the original signal train from the receiver 2, the output from the mixer being applied to a Y-plate of the cathoderay tube 8. The time-base 9 is triggered by the transmitter-synchronizing pulses which are also fed to a blocking circuit 10a which blocks the receiver during radiation of the pulse from the transmitter 1. In a modification, Fig. 3, the signal-to-noise ratio of the selected echo is increased by delaying it at 30 for a period equal to the pulse recurrence period and mixing the delayed signal at 31 with the undelayed selected echo. This process may be repeated by adding to the output of mixer 31 another delay circuit, the output from which is mixed with the selected echo as applied to circuit 30. The input to circuit 30 may be limited by a clipper valve as in Fig. 1. The Specification as open to inspection under Sect. 91 describes a further embodiment, Fig. 3 (Cancelled, not shown), in which the signal-to-noise ratio of a selected echo is increased by causing it to trigger a multivibrator, the output from which is differentiated and shaped. This subject-matter does not appear in the Specification as accepted.

Abstract: 1393524 Pipe couplings; valves AVERY-HARDOLL Ltd 13 April 1972 [13 April 1971] 9296/71 Headings F2G and F2V In a quick-release coupling, e.g. for refuelling an aircraft on the ground, valve operation may be effected pneumatically or by means of a spring. The coupling may be secured to a fuel reservoir hydrant (not shown), by a bayonet connection, made by introducing rollers 18 into the axial parts of L-shaped slots in the hydrant. On rotating the housing 10, to lock the rollers 18 in the circumferential parts of the slots, tongues 24 are retained in the axial parts and prevent ring 19 from being rotated. Rod 73, which is mounted on housing 10, is thus carried away from stop 23, which is fixed to ring 19. The rod 73 is spring urged so that, on being removed from stop 23, it retracts axially away from snail cam 72, thus unlocking shaft 71 and the link arm assembly 70, 34 for the main valve member 32. On completing the bayonet connection, pip 43 opens a corresponding valve member in the hydrant and liquid, under reservoir pressure, flows through holes 44, duct 41 and out of holes 42 into space 38, where it exerts pressure on balancing piston 33, which is essentially insufficient to open the valve member 35. Space 38 is vented, through duct 48 and restrictor valve 45, to the interior 11 of the housing. To disenable the pneumatic control and prevent the valve member 32 from being opened inadvertently, when the coupling is released, port 55 in spool valve 56 is vented to atmosphere. However, as rod 73 retracts axially, it carries the spool 60 with it to connect port 55 to port 62 and thus provide a path, for compressed air, from port 53 to cylinder space 69. A remotely located changeover air valve is operated, through a dead man's control, to supply air to port 53 and to vent port 52 to atmosphere. Piston rod 34 is thus driven axially to open valve member 32 at a speed controlled by needle valve 64. When valve member 32 is open, cam 72 is positioned to prevent rod 73 from being moved, by handle 75A, clear of stop 23, so that the bayonet connection cannot then be released. On reversing the connections at ports 52 and 53, piston 35 returns the valve member 32 to the closed position, in which rod 73 can be moved, by handle 75A, to disenable the pneumatic control and allow the housing 10 to be rotated, relatively to the hydrant, to disengage the bayonet connection.
