Title: Improvements in or relating to rocket discharging gear for aircraft
IPC: B64D1/04
Filed: 1943-09-09
Abstract: 579,381. Rocket discharging gear for aircraft. MOLINS, D. W., RUAU, F. F., BALDWIN, H. W., and MOLINS MACHINE CO., Ltd. Sept. 9, 1943, No. 14843. [Class 9 (ii)] Retractable rocket-discharging gear for aircraft has rail units, with the rockets thereon ready for discharge along the rails, carried on supports which in the inboard position permit the rockets to be stowed side by side with their fins staggered and overlapping, means being provided for lowering the supports and opening the units apart as they reach the outboard firing position. Reverse movements take place when the supports are raised for stowing. In the form shown in the stowed position in Fig. 1, . rail units 15, each supporting a pair of rockets R in staggered formation, are carried by parallel arms 5, 6, pivoted to supports 2, 3 depending from a fixed bar 1. The arms are connected by a bar 13 and their free ends are attached to pillars 9 which space the rail units vertically. The pillars are mounted for axial rotation and carry arms 12, 14, 19 pivoted to the rail units for closing and spreading them during the raising and lowering movements, this being effected by a cam 10 on the arms 6 engaging a follower 11 on the arms 12. The power means for raising and lowering the arms 5, 6 and the bar 13 comprises an electric motor 34 for rotating a nut 31 engaging a pivoted screw 27. Additional pivoted stays 42 are provided. A free-wheel brake device associated with the motor compensates for the difference in loading when the gear is moved up or down. The bar 1 is supported from the fuselage 52 by a releasable hook 49 as used for supporting bombs, the arrangement permitting of the rocket gear being jettisoned, if desired, after opening the bomb doors 53. A switch panel is provided inside the fuselage to permit of selecting either the port or starboard rail units for lowering into the discharge position, limit switches 56 being provided on one of the arms 42 to facilitate reversal of the motor at the extreme positions. The arms 19 are mounted for adjustment to effect dispersal of the field of fire. In a modification, the cam 10 is dispensed with and the rail units are supported by arms 5 of different lengths to effect opening out of the rockets in the firing position and overlapping thereof in the stowed position.

Title: Improvements in or relating to diversity radio telegraph systems
Inventor: TERRY VICTOR JOHN
IPC: H04B7/02
Filed: 1952-06-17
Abstract: 709,793. Radio receiving systems. STANDARD TELEPHONES & CABLES, Ltd. June 17, 1952, No. 15212/52. Class 40 (5) In a diversity receiving system for frequency shift telegraph signals the sum of the voltages of the demodulated mark or space versions actuate the output relay and biased rectifiers are arranged automatically to exclude from this the weaker or weakest versions when the amplitude of the latter falls below a certain fraction of the strongest version. As shown, mark and space voltages for an electronic relay are applied over leads band c to a pair of valves V5, V6 whose outputs are applied over decoupling resistors R31, R35 to load resistors R46, R38, R34 and to actuate an output relay V9, V10. Different versions of the mark and space signals are also applied over leads e and f to a pair of valves V7, V8 whose outputs are also fed over decoupling resistors R32, R36 to the load resistors R46, R38, R34 and so added to the respective outputs of valves V5, V6. The amplitudes of the mark and space signal versions are also detected by rectifier circuits branching off from the main signal paths before the limiters and discriminators and applied over leads d, g to voltage dividers R44, R46 and R45, R46, and between the points of voltage divided and the cathode circuits of valves V5, V6 and V7, V8 are inserted rectifiers W1, W2 so that the voltage applied at d or g is inoperative if it is less than a fraction of that applied to g or d respectively, and the valve pairs V5, V6 or V7, V8 are in those conditions biased to cut off and add no output to the ouput relay. The valves V9, V10 operate a change-over contact co. Due to the different paths taken by the same signal before reaching the receiver antennas an uncertainty as to the correct instant of change-over during the delay interval may arise in the sum of the demodulated signal versions. This is avoided by inserting time-constant networks R15, C1, R19, C3, R17, C2, R21, C4 in the inputs to the valves V5-V8.

Title: Apparatus for dragging along a submerged structure
IPC: F16L1/20
Filed: 1971-05-17
Abstract: 1306902 Hauling R J BROWN & ASSOCIATES CORP 17 May 1971 [27 May 1970] 15334/71 Heading B8B [Also in Division F2] A pipe laying tool (e.g. a pipe burying device) or other subaqueous structure is towed by a cable 5 secured to a member attached to the lowermost end of a post 2. The post is universally pivoted at 3 to a surface vessel 1, the post also being capable of vertical movement with respect to the vessel. A cable 8 is passed from a winch 10 via a constant tension device 9 to a sheave 7 and thence to a point on the seabed ahead of the device being towed (in the direction of towing), where its end is anchored. Ropes 4, 4a are provided to raise and lower the post, respectively. In use the cable 8 is wound in to cause the member at the bottom of the post to move and thereby tow the device, the vertically upward force on the post 2 being countered by rope 4a. Echo sounder 13 is linked to the means controlling ropes 4, 4a so that the member on the bottom end of the post may be kept at a constant height above the sea bed despite the motion of the vessel on the vessel. The universal joint 3 allows the bottom of the post to remain substantially in line between the point of anchoring of cable 8 and the device being towed despite the motion of the vessel. Further, the vessel may be kept heading into the sea or swell even if this is not the direction of towing. The member at the bottom of the post may have a fracturable joint 11 whereby, if an obstruction is encountered by the device being towed, the base will break off. A line attached to a buoy 12 allows retrieval of the lost device. If the device being towed is powered the power supply lines 14 may pass down the inside of the post 2 from the vessel 1.

[Also in Group XXXVII] A device to enable the current in a circuit to be measured without breaking the circuit comprises two springs 1, 2 secured to an insulating block 5 and having tags 6, 7 for connection to the circuit, and a rigid member 14 connected to the spring 1. The springs and the member are electrically connected through contacts 10, 11, 12 and 13. A probe 15 connected to one pole of an ammeter is passed through an opening 17 in the member 14 thus depressing spring 1 and separating contacts 10 and 11 as shown, the circuit being meanwhile maintained through contacts 12, 13. The spring 2 is then pushed down against a stop 21 by a probe 16 connected to the other ammeter pole, thus separating contacts 12 and 13 so that the ammeter is now in circuit. An insulating cover 25, Fig. 4, is secured over the device, holes 26, 27 being provided for the probes. Corresponding recesses 30 and 31 in the support 5 and the cover 25 support rods 32 so that several devices may be mounted side-by-side.

In a method of detecting phosgene, volumetrically controlled samples of a gas such as air, suspected of containing small amounts of phosgene, are passed through an absolute filter to remove all entrained solid particles and into contact with a source of ammonia whereupon any phosgene present reacts to form very small solid particles of ammonium chloride and urea, which by themselves are not large enough to cause any significiant light scatter so that they are first carried to a humidifier in which the relative humidity of the gas sample is increased to near saturation, the pressure of the gas then being suddenly reduced causing water vapour to condense on the ammonium chloride and urea particles in order that they may be increased in size and detected by their ability to scatter light by use of a condensation nuclei detector. The source of ammonia may be ammonium carbonate in solution or in solid form. Hydrazine or amines or mixtures of these with ammonia, if desired, may be used in place of ammonia itself.
