Title: Improvements in or relating to impellers or rotors, more particularly for cooling fans
Inventor: NORTON JAMES LANSDOWNE
IPC: F04D29/34
Filed: 1950-04-03
Abstract: 681,570. Axial-flow fans. BRISTOL AEROPLANE CO., Ltd. March 14, 1951 [April 3, 1950], No. 8361/50. Class 110(i) An impeller or rotor comprises a number of blades of thin material attached to a rotary member constructed so that as the blades deflect due to inertia loading of the unsupported part the length of the part is progressively reduced. This prevents the blades from being sharply resonant to any particular frequency of vibration. An axialflow cooling fan for a helicopter engine comprises blades 10 attached to a radially extending flange 11 on the engine flywheel. The root ends 13 are flat, with a slot 14 to clear the flange 11. Clamping bolts 16 pass through holes 15 in the blades and corresponding holes in the flange 11 and clamping blocks 17. In the embodiment shown, ,a pair of blocks 17 is provided between each pair of blades, but instead there may be a single block which straddles the flange 11. Beyond a line y, the surfaces 19 of the blocks 17 are arcuately curved so as to diverge from the blade roots 13. Thus, when a blade is deflected, the outermost point of contact with a clamping block shifts progressively along the length of the root 13, so that the length, and consequently the resonant frequency, of the unsupported part of the blade is progressivelyaltered. The portion 20 is curved in cross-section and may be twisted so as to have a reduced pitch angle at the tip. The blocks 17 may be of light alloy, fibre or plastic. The blades 10 may be attached or restrained at both ends.

Title: Magnetic repeater or compass
IPC: G01C19/40
Filed: 1941-07-02
Abstract: 550,399. Repeating compass readings. BENDIX AVIATION CORPORATION. July, 2, 1941, No. 8369. Convention date, June 13, 1940. [Class 40 (i)] Magnetic compass readings are conveyed to a remote indicator by means of a permeable intermittently-saturated pick-up member which is disposed within the field of the magnet and controls the rotation of a motor coupled to the indicator. The pick-up member 14 which is of the kind described in Specification 549,528, comprises saturating windings 22, 23 fed with A.C. and output windings 29, 30 connected through an amplifier 34 to one phase winding 35 of a two-phase induction motor 19, the other phase winding 38 being constantly energized with A.C. The magnet 11 is normally at right angles to the member 14; and any departure from this relationship produces a resultant voltage in the output of the windings 29, 30, to start the motor 19, which drives the member 14 through reduction gearing until the normal relationship is again reached. The shaft 15 of the member 14 carries a pointer 40 moving over a scale 41 and also the rotor 16 of a Selsyn 17 which controls remote indicators 51, 52. In another arrangement, the output windings of a 3-limbed pick-up member 55 are connected to the stator 60 of a Selsyn the rotor winding 62 of which is connected through an amplifier 34 to the winding 35 of the induction motor 19, and the latter serves to drive the rotor 63 to a null position to set a pointer 72 in accordance with the movements of the compass magnet 11. The motor 19 also drives the rotor of a selsyn 17 which controls remote indicators 42, 43. In order to correct the readings of the pointer 72 when the magnet 11 is situated in an environment which distorts the earth's field, the rotor 63 is mounted on a hollow shaft 82 which is driven from the motor shaft 69 through a flexible linkage 78 controlled by the movement of a roller 77 on a cam track 74, the latter being adjusted at intervals in accordance with observed differences between the true and apparent bearings. The pointer 72 indicates the true bearing on a scale 83, while the shaft 82 may carry a scale 80 for indicating the uncorrected bearing. A course selecting disc having lubber lines 88 and a pointer 89 may be set by means of a knob 84, which also serves when advanced for introducing the variation between the magnetic and geographic bearings by rotation of a disc 90 on which planetary gearing 70 is mounted and of the stator of the Selsyn 17. Specification 537,514, [Group XXXVI], also is referred to.

Title: Improvements in packaging machines
IPC: B29C65/04
Filed: 1950-04-05
Abstract: 716,783. Packaging - machines. RADO, L. April 5,1950, No. 8624/50. Class 94 (1) In a machine for producing thermoplastic containers, filled with liquid or paste, by flattening and welding together opposed walls of a length of filled tubing at spaced points, the filled tubing 9. Fig. 1, is fed between endless chains 1 and 2 passing over driving sprockets 3, 4 and 5, 6 and carrying jaws 7 and 8 respectively which are spaced apart along the chains by distances equal to the length of one container and move in registering relationship along the lower run 1a of the chain 1 and the upper run 2a of the chain 2. The jaws are guided by insulated members 10 and 11 which are so shaped that the jaws are progressively moved closer together to flatten the tube at spaced points, thereby displacing the filling from the areas where welding is to be effected. The jaws then move on to conductive portions 12, 13 of the guide members, whereby they are connected to a source of high-frequency current to effect the welding, the portions of the guide members immediately in advance of the portions 12, 13 being sloped inwardly so that the jaws are moved closer together to compensate for the softening of the walls of the tubing when it is heated. To avoid sparking, each jaw 7 is arranged to close a switch 15 in the electrical circuit after it has engaged the portion 12 and to open the switch before it leaves the portion 12. The construction of the jaws is shown in detail in Figs. 2-4, each jaw 7 comprising a central part 7a, slidable against the action of a spring 16 in a casing 17 engaging the guide 10, and insulated outer parts 7b, movable relative to the part 7a against the action of springs 7c which protect the softened areas of the tubing in contact with the filling. Each jaw 7 houses a slidable cutter 21 which is moved downwardly by a fixed cam 23 into a recess 24 in the co-operating jaw to sever each filled container from the tubing. The movement of the jaws towards one another is limited by insulated stops which may be adjustable, see Figs 5-7 (not shown), and each jaw 8 is fitted with flared guides 20, Fig. 8 (not shown), which engage the co-operating jaw 7 as the jaws move on to the adjacent runs of the chains to prevent relative longitudinal movement thereof. Before being fed to the apparatus of Fig. 1, the tubing 9 may be subdivided longitudinally by endless metal bands 25, 25a, Fig. 13, heated by electrical resistances 26 and driven at the same speed as the chains 1, 2, the bands being cooled by air jets 27 after they have effected the longitudinal welding of the tubing.
