Patent GB-722891-A (GB)
Abstract: 722,891. Ignition systems. BENDIX AVIATION CORPORATION. June 5, 1950 [June 9, 1949], No. 14023/50. Class 7 (4). [Also in Group XXXVII] In a low-tension ignition system having a storage condenser 17 connected to be charged by a source of electrical energy such as a magneto, there is provided means, for example a distributer rotor 23 with contacts 28, 29 bridged by a semi-conductor 30, to partially discharge the condenser into a second condenser 33 to ionize a spark gap, such as that between the rotor 23 and each in turn of a plurality of fixed contacts 31, to render the gap conductive to the charge of the storage condenser 17, so enabling the latter to discharge across a lowtension sparking plug 42. The semi-conductor 30 may comprise fused mixtures of such material as silicon carbide and iron with aluminium oxide or other ceramics. The magneto secondary winding 15 which has an earthed centre tapping 16 is connected to the condenser 17 through two half wave rectifiers 19, 20, or one full-wave rectifier ; the circuit may be energised by any direct or alternating current source. The condenser 17 is connected to a conductive ring 22 in the distributer rotor 23 (see also Group XXXVII) by a lead 24, the rotor semi-conductor 30 being in physical contact with the inner surface of each of two electrode plates that are spaced apart to form a gap, each plate being secured to one of the contacts 28, 29 ; the latter successively move into spaced relationship with the fixed contacts 31. The ring 22 is connected to one contact 28, the other of which is in a circuit comprising lead 32, the condenser 33 shunted by a resistance 36 both integral with the rotor, and a brush 34 on the rotor which successively contacts members 37 on the distributer cover, all the latter members being permanently connected to earth 38 through a central terminal 35 ; the condenser 33 and resistance 36 may be inserted between the terminal 35 and earth. When the electrode plates are opposite a fixed terminal 31 and brush 34 is in contact with one of the corresponding contact members 37, the condenser 17, which is continuously charged by the magneto, partially discharges across the surface of the semi-conductor 30, the circuit being completed through the earth connection from terminal 35, to ionize the distributer gap so that when condenser 33 is fully charged the remainder of the energy from the storage condenser effects high-frequency energisation of the sparking plug. The charge built up on condenser 33 discharges simultaneously with the remainder of the charge on the storage condenser in order to additionally energise the plug.

Patent GB-785399-A (GB)
Abstract: 785,399. Gyroscopic apparatus. BENDIX AVIATION CORPORATION. Nov. 2. 1955 [Nov. 15,1954]. No. 31353/55. Class 97(3) In a rate-of-turn gyroscope, relative movement between the rotor support and the frame member is restrained by means of a resiliently flexible rod-like element secured to one of the members and slidable relatively to the other, which element extends through the pivotal axis of the rotor supporting member in its centred position and is resiliently flexed on precession of the rotor. As shown, a bracket 13 mounted on the rotor casing is pivoted to an arm 15 of a dashpot 17, and carries a pin 25 embraced by a forked member connected to a pointer which moves over a dial to indicate the rate of turn. A springy rodlike member 31 is secured at one end to the bracket 13 and extends through the axis of rotation of the rotor when in the rest position. The other end of element 31 slides in a jewel bearing 33 mounted in a member 35 threaded to the frame 5 of the instrument. The sensitivity of the instrument may be adjusted by moving the member 35 axially by its thread. A lock nut 37 holds the member 35 in its adjusted position. On precession of the gyroscope rotor, the rod-like element 31 is flexed and slides in the jewel bearing 33. The flexure of the element exerts a couple on the rotor or supporting member, to return it to neutral position when precessional forces have been removed. In an alternative arrangement, the rod-like element 31 is fixed at one end to the frame 5, and slides in a jewelled bearing mounted on the bracket 13. The instrument may also include an inclinometer (not shown).
