Patent GB-2448992-A (GB)
Title: Composite gear having a permanent compressive stress at the root portion of each tooth
Inventor: LUNIN STEPAN V
IPC: B21H5/00
Filed: 2008-05-01
Abstract: The composite gear 10 includes a body portion 28 having a plurality of teeth 14. The gear 10 is formed by placing it in a suitable tool 30 such that a compressive stress (hoop stress) 32 is exerted on the teeth 14 adjacent the root portion of each tooth (fig 3A). A portion of the gear adjacent the teeth is wrapped with a resin fibrous material 22,24 that is allowed to cure while the compressive stress 32 is maintained on the gear. When the resin fibrous material 22,24 has at least substantially cured and the gear 10 is removed from the tool 30, a permanent compressive stress is formed at the root portion adjacent each tooth. The compressive stress counteracts the tension stress that is experienced at the root portions of the teeth when the gear is in use, thus significantly strengthening (i.e., toughening) the gear and increasing its fatigue life. This allows smaller and lighter gears to transmit the same forces as larger prior art gears. The invention may be applied to different types of gearing including spur, ring or bevel gears. The fibrous material may be glass, Kevlar ¹, boron or carbon.

Title: Improvements in bone conduction devices
IPC: H04R11/00
Filed: 1949-04-13
Abstract: 684,954. Instruments for deaf persons. SNEATH, O. B., and KNIGHT, E. A. April 13, 1950 [April 13, 1949], No. 10074/49. Class 40 (iv). In a bone conduction receiver the magnetic system which includes at least one permanent magnet and at least one electromagnet is connected to an armature by one or more resilient members which may be integral with the armature, and a housing is connected to the members(s) at a point intermediate the armature and the magnet system, the point being so disposed that the amplitude of oscillation thereof relative to the magnet system is not greater than half that of the armature. Such a system has two principal modes of vibration, the frequencies of which are arranged to occur in the ranges 200-500 c.p.s. and 2000-5000 c.p.s. respectively. In one embodiment the armature is made integrally with the resilient member, the whole comprising a rectangular plate 7 (Fig. 5) cut with slits 8 to embrace the central area 20 which forms the armature proper. Two symmetrical points 9 each about one-third of the distance along one of the resultant resilient members from the fixed corner points to the point of maximum oscillation are chosen at which to connect the housing. The magnetic system consists of four permanent magnets 10 (Figs. 7, 8) arranged magnetically in parallel with one another and in series with an electromagnet 11 and has a centre circular pole 12 extending upwardly from a base-plate 121 and surrounded by a magnetically-insulated ring 13 outside which the other polepiece 14 is constructed as a rectangular plate 15 with a central circular hole. A radial slit 16 is provided to reduce eddy currents. The armature system is spaced from the magnet by two non-magnetic spacers 18 (Fig. 8) in diagonally opposite corners of the plate 7 and is secured to the plate 15 by non- magnetic screws 19. Similar screws 19 at the other corners serve to adjust the armature system relative to the magnet. The points 9 on the plate 7 are connected as by soldering to a flat connecting-member 21 (Figs. 9, 10), which lies adjacent to the armature system and connects it to the housing 22 of conventional type. The member 21 may either have a thin transverse strip 24 (Fig. 9), or the centre portion of the strip may be cut away, Fig. 11 (not shown), the points 9 being connected at the roots of the strip 24 in each case. The member 21 is firmly held between the lid 26 (Fig. 10) and the main body of the housing. The openings 27 are for the electrical leads to the electromagnet 11. In a second embodiment (Figs. 12, 13) a reed armature 30 is used, the points 31 being fixed to the magnet system, the end 32 forming the armature proper, and the projections 33 providing the drive-points for the housing. The magnetic system comprises a pair of permanent magnets 34 arranged magnetically in parallel with one another and an electromagnet coil 35 surrounding the armature 32. The armature vibrates in the gap between the pole-pieces 37.

Abstract: 558,048. Controlling aircraft. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G., LLOYD, J., and MURRAY, C. V. July 21, 1942, No. 10163. [Class 4] An aircraft having an extension flap at the trailing edge of a wing and an aileron at the trailing edge of the flap is provided with spoiling means operable upon upward movement of the aileron after the flap has been moved rearwardly. An extension flap 12 supported on links 15, 16 as described in Specification 558,043, and an aileron 13 operable by chain and link gear described in that Specification and involving an arm 40 pivoted at the lower end of the link 15, is provided with a spoiler 18 carried by an arm 19 on a shaft having an arm 33 linked to a lever pivoted on the wing at 35 and having a cam surface 36. When the flap is extended as shown and the aileron is in normal position, the arm 40 is in contact with the cam 36 so that any movement of the arm to raise the aileron displaces the cam and projects the spoiler 18 on that side of the aircraft. In the form shown in Fig. la, the spoiler 18 is mounted on the flap 12 and is projected into the gap between the flap, when extended, and the main wing upon upward movement of the aileron. The aileron is operated by a link 25 connected to an arm 24 mounted on the rear supporting-link 16 of the flap, the arm 24 being moved by means similar to the means disclosed in Specification 558,043. In the position shown, a stop 27 on the rod 25 is clear of a lever 20 for actuating the spoiler but when the flap 12 is extended the arm 24 rises to bring the stop 27 into contact with the lever 20 so that movement of the rod 25 to raise the aileron causes the spoiler 18 to be projected. The spoiler may be operated also upon the undercarriage becoming loaded or upon application of the wheel brakes as described in Specification 558 049. The aileron may be on the outboard flap of two flaps extending along the whole of the trailing edge of a wing as disclosed in Specification 558,044, or it may be mounted as described in Specification 558,045.
