Title: Improvements in or relating to density-sensitive apparatus
IPC: G01N9/16
Filed: 1958-01-21
Abstract: 863,021. Electric indicating and control systems. LIQUIDOMETER CORPORATION. Jan. 21, 1958 [Jan. 31, 1957], No. 2005/58. Class 40 (1). [Also in Group XX] A device sensitive to changes in the density of a fluid comprises a float system immersed in the fluid and including a temperature-sensitive element mounted on the float system and having a portion movable in response to changes of temperature in a direction to move the centre of gravity of the system to compensate for changes of buoyancy due only to changes of temperature, the mounting of the temperaturesensitive element on the float system being adjustable. The form shown in Fig. 1 comprises a float 13 carried on an arm 11 pivoted at 12 and carrying a contact 14. A weight 20 is adjustable on a screw 19 carried on one limb of a bimetallic strip 16 secured by a screw 17 to the end of the arm 11, the hole in the strip being slotted to allow adjustment in the direction of the arrow 22. In another form the screw 19 is attached directly to the arm, the temperaturesensitive means being a fluid-filled (preferably liquid-filled) bellows secured at one end to an adjustable point on the arm with its axis parallel to the arm. In the system shown in Fig. 4 a number of float systems 58, 59, 60, of graduated buoyancies, are arranged in a by-pass on a pipeline and, as they are successively operated by changes of specific gravity, their contacts short out successive impedances 51, 52, 53 in one arm of a bridge network. Any unbalance voltage is fed to an amplifier 63 driving a motor 64 which adjusts a resistance 61 to rebalance the bridge. A change in specific gravity indicates that a different liquid is being fed to the pipeline and the rotation of the shaft 66 may cause one of a number of cams 71 to close a contact 72 controlling a system 75 which operates a valve 78 in the appropriate one of a number of discharge pipes 81, 82, 83. Specification 684,348 is referred to.

Title: Improvements in and relating to apparatus for sealing-in discharge lamp cathodes
IPC: H01J9/32
Filed: 1948-01-22
Abstract: 676,961. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 22 1948 [Jan. 22, 1947], No. 2012/48. Class 39 (i). [Also in Group XI] A discharge lamp electrode 13 is sealed into the end of a short vitreous tube 23, the pinch being formed directly on the support wires, thus forming an end portion for subsequent attachment to the main portion of the envelope. The operation is carried out in a head 1 of a multi-head machine, the assembly being mounted during indexing through a group of work stations A. The exhaust tube 4 is inserted into a longitudinal opening in a holder 5 and rests on an adjustable hollow stop 6. The lead-in wires 14, 15 of the electrode 13 are then threaded down longitudinal openings on either side of the exhaust tube, resting on adjustable stop rods 18, 19 in the same holder 5, which comprises two halves 5<SP>1</SP>, 5<SP>11</SP> held closed by springs 10, 10<SP>1</SP> extending between one head and the next. Finally, the envelope 23 is placed in position, resting on a stop plate (not shown). Rotation beyond stations A to the next station B releases a shaft 32 from restraint, allowing rotation under the action of springs 41, 42 of double-throw cranks 38, 39 which close successively two pairs of jaws, 26-27 clamping on the envelope 23 and 28-29 clamping on the lead-in wires 14, 15. At this station the first of a set of burners 49 or 49<SP>1</SP> mounted in pairs on manifolds 51 or 51<SP>1</SP> is moved into operation by similar mechanism to that disclosed in Specification 223,204, [Class 39 (ii)], while a centring rod 53 held in an upper position by a spring arrangement 55, 59 is moved downwards by an arm 57 on an actuating rod 64 into engagement with the electrode 13, being held thus by the same spring. A shield 52 protects the mechanism from the heat of the burners. At the following group of stations C more intense heat is applied, whereby the envelope begins to fuse, jets of air being directed upwards through holder 5 whose pressure and cooling effect maintain a passage through exhaust tube 4. At station D a pair of jaws 68, 69, Fig. 8, clamp together to form the pinch, while a mandrel 67 slides upwards to maintain the exhaust tube passage, the pinch being rounded out by a hot-air jet. At the final work station, after several annealing stations, the centring rod 53 is raised out of engagement with the electrode, rollers 84<SP>1</SP> engage a cam causing halves 51 and 5<SP>11</SP> of the holder to separate, and the jaws 26-27 and 28-29 once more constrained to open, permitting removal of the assembly. The centring rod 53 may be swung to one side if necessary.

Title: Improvements in fuzes for aerial bombs and like missiles
IPC: F42C15/295
Filed: 1944-02-07
Abstract: 582,574. Fuzes for aerial bombs &c. MIDGLEY, A. H. Feb. 7, 1944, No. 2271. [Class 9 (i)] A fuze for aerial bombs and like missiles of the kind in which a detonator carrier is slidable transversely in a slot in the body of the fuze and held in the unarmed position against spring resistance by a releasable device, has the spring located in an eccentrically disposed bore in said carrier, the carrier having a small hole in its upper surface into which a pointed tool can be inserted to facilitate movement of the carrier to compress the spring during assembly of the fuze. In the application of the invention to a direct-action fuze, the carrier d with spring f and aperture e to hold the detonator, is held in the unarmed position in the slot c in the fuze body by a pin g bearing against a spring lever h located in a slot h<1> in the fuze. The lever h is withdrawable by a screw cap i rotated by a vaned member k, thus releasing the pin g and allowing the carrier to be moved by the spring f into the position in which the detonator is in line with the striker l. A flash passage m is provided to dissipate the flash of the detonator harmlessly in case of accidental premature ignition. The small hole in the upper surface of the carrier is not shown in the drawings. The invention is also described as applied to a delay-action fuze similar to that forming the subject-matter of Specification 576,664 in which a spring-loaded striker is held from operation by balls engaging a conical surface on the striker and restrained from lateral separation by a movable sleeve surrounding the balls. An extension of this sleeve engages the edge of the detonator carrier and holds it in unarmed position. Movement of the sleeve releases the carrier which moves into the armed position and then releases the balls, allowing the striker to operate. Delay action is by lead shear wire holding the movable sleeve to the fuze body, the wire being cut through after a predetermined time under the force exerted on the movable sleeve by the striker spring after an inertia-operated locking device has been released on impact.

Title: Improved cavity resonator for atomic resonance devices
IPC: H01S1/00
Filed: 1965-01-19
Abstract: 1,067,328. Molecular beams. VARIAN ASSOCIATES. Jan. 19, 1965 [Jan. 28, 1964], No. 2368/65. Heading G6P. A caesium atomic beam tube, for use in a frequency standard circuit which has a low temperature deviation, is injected with radio frequency energy, from a wave-guide system coupled to the beam. The beam strikes a detector when the injected R.F. energy is at the caesium resonance frequency. The caesium beam, which is equally populated by atoms of both parallel and anti-parallel alignment states of the nuclear magnetic dipole and the valence electron magnetic dipole, is passed through the field of the first permanent magnet which selects atoms of one state which are deflected, as a beam, into the wave-guide system. A second permanent magnet intercepts the beam of single state atoms on leaving the waveguide and deflects it away from the detector. When, however, the injected R.F. energy is at the atomic resonance frequency, the atomic resonators change state and are deflected by the second magnet on to the detector. For other frequencies, the resonance of the atoms does not occur and the beam misses the detector. A detector current indicates that the R.F. frequency is equal to the caesium resonance. The beam source, magnets, wave-guide system and detector are mounted along the longitudinal axis of a stainless steel tubular envelope maintained at a vacuum of 10<SP>-7</SP> mm. Hg. The wave-guide is formed as a Y-shaped cavity resonator and the beam passes through the extremities of the two arms. Coupling into the wave-guide is effected through the stem of the Y which projects through the side wall of the envelope and which has a reflectionless vacuum tight window. The wave-guide sections interacting with the beam have a high Q, while the stem incorporates a loss member to lower the total Q value.
