Title: Improvements in or relating to a frangible aerial tow target
Inventor: HOPPER ROBERT JOE
IPC: F41J9/10
Filed: 1956-05-28
Abstract: 810,138. Towed aerial targets. DEL MAR ENGINEERING LABORATORIES. May 28, 1956, No. 16493/56. Class 4. [Also in Group XL(c)] A frangible aerial towed target comprises a streamlined elongate rigid body member made of non-metallic material permeable by radar waves, reflector means carried internally of the body for reflecting externally propagated radar-waves, and stabilizing fan elements carried by the trailing portion of the body. In Fig. 1, the target is assembled from three sections 11, bonded at 12. Fins 25 are set in slots formed in the sections. All the pieces are moulded or machined from a foamed plastic, e.g. cellulose acetate or polystyrene, and bonded together. Strands of nylon cord 22 are anchored in the body and attached to releasable hooks 23 on a pylon 21 on the towing aircraft. A nylon cord 16 is formed into a coil 15 located in the target, one end 17 being anchored in the target and the other anchored at 24 to the pylon, whereby the cord is payed out under the drag of the target when released for towing. An electrical resistance element 31 may be energized to burn through the cord to disconnect the target. A radar wave reflecting element 26 comprises three discs 27 of corrugated paper laminated with aluminium foil, the discs meeting at right angles, and fitting into slots formed in the body. In Fig. 6, four elements 41 compose a nose section, and four elements 42 a tail section. All the elements fit onto a low strength radar reflector 48 and are bonded to the reflector and to each other. A fin assembly 44 made of balsa wood is bonded into slots 49 in the tail section. Fig. 9 shows a variant in which the target is made in three sections, each of four elements, and comprises two radar reflectors 61, 62. The fins comprise a pair 64 (one shown) at a positive dihedral angle and a single downwardly pointing fin 63. Lines 66 extend one from point 67 to point 68, and one from point 69 on fin 64 shown to a similar point on the fin 64 not shown. These lines reinforce the target, and a hook on a towing cable 65 engages one line. In Fig. 13, the body sections 111, 112, 113 and 114 are made of moulded impregnated paper pulp. Section 112 is joggled and flanged at 115, 116 and bonded to section 111, and sections 113, 114 are similarly connected. Sections 112 and 113 are bonded to a cylindrical face of a foamed plastic member 119 containing a radar reflector. The aft section 114 is reinforced at 134 by corrugated paper bulkheads. The fins 139 are of moulded foamed plastic, and the tip 144 of each is bent so that the target rotates in flight. The towing cable is attached to a swivel pin 147 at the nose mounted in a sleeve 148 attached to a plate 151. Sand 154 is retained between two plastic discs 153, 155 to make the target nose heavy. The fins may be formed of impregnated paper pulp reinforced by corrugated paper webs and paper honeycomb.

Abstract: 788,501. Making bellows. ROBERTSHAWFULTON CONTROLS CO. May 29, 1956 [Oct. 24, 1955], No. 16605/56. Class 83 (2). In an apparatus for setting the length of flexible bellows 20, Figs. 1, 3, an indicator 68 measures the free length of the bellows while the setting means is held in a preset position during the return stroke. The bellows 20 are mounted on a pedestal 14 and set by the actuation of a pneumatic ram 22 having a frame 56 attached to the piston 28 and carrying the indicator 68. An adjusting nut 36 on the upper part of the piston 28 engaging a stop 30 limits the setting stroke. A plunger 58 is freely slidable in the lower cross-member 54 of the frame and has a flange 64 engaging the bellows 20 during setting. On the return stroke the plunger 58 remains in engagement with the bellows under its own weight as the crossmember 54 rises to a fixed position so that the indicator 68 engaging the top of the plunger 58 indicates the free length of the bellows. Location of the frame 56 on the return stroke is provided by a latch 80, pivoted at 82 to permit downward movement of the cross-member 52 over its inclined surface 88. On the return stroke the cross-member 52 engages the underside of the latch 80 and is held in position for reading the indicator 68 until the latch is automatically released by a solenoid 76 operated from a timer which controls the sequential operation of the apparatus.

Abstract: 1359252 Lighters FLAMINAIRE 11 April 1972 [16 April 1971] 16691/72 Heading F4F A gas reservoir for a lighter is provided with a regulating device for allowing the gas under pressure to escape with a variable and limited flow-rate, and comprises a threaded part 1 (the axial position of which controls the flow of the gas) which is rotatable in the tapped portion 2 of the reservoir. A control member 3 comprises a thin portion 4 which is engaged in a diametric slot 5 in the threaded part 1 and which has two radial protuberances 6 arranged to engage in the threads 7 of the tapped portion so that the axial position of the control member is fixed when adjustment is not being made. The control member is positioned by forcibly moving the member axially, the protuberances 6 lifting over the threads of the tapped portion 2. The outer section of the control member comprises a disc member 14 having a slot 15 in which a screw-driver or similar tool may be used. A washer 8 is interposed between the control member 3 and the surface 2a of the tapped portion 2. This washer has peripheral notches 9 in which engage ridges 10 formed on the inside of a bore in the wall of the reservoir (Fig. 2, not shown). The inside edge 8a of the washer 8 has two angular stops (11, 12) limiting the rotation of the control member 3 by abutting its narrowed portion 4, which provides maximum and minimum adjustment for the gas flow rate (Fig. 2, not shown). Procedures for assembling the regulating device and setting the adjustment range of the flame are described.
