IPC: B60R21/05
Filed: 1972-10-31
Abstract: 1415181 Steering columns J R HOLLINS 31 Oct 1972 [1 Nov 1971] 50172/71 Headings B7H and B7B A padded cushion 12 is arranged below a steering wheel 10 such that when the thrust of the driver is thrust against the steering wheel the wheel sinks into the cushion. A rigid support 16 positioned underneath the cushion is secured to a section 17 of instrument panel 13. A steering column 14 includes a round tube 34, Fig. 4, attached to the hub of wheel 10 and a collar 38. An hexagonal outer tube 40 is also secured to collar 38, while an inner tube 42 telescopically engages the tube 40 for rotation together. A tube 45 fastened to the tube 42 is attached to steering mechanism (not shown). A member 50 secured to tube 40 has spring fingers 49 provided with inwardly protruding portions 52 each engaging an indentation (53) Fig. 5 (not shown) to prevent telescoping of tubes 40 and 42 unless sufficient force is applied to the steering wheel 10 when the drivers body is thrust forwardly. A bracket 32 supports a collar 54 which supports column 14 while allowing rotation and axial movement of outer tube 40. In another embodiment Fig. 3 (not shown) tube 34 is omitted and end 41 of tube 40 is directly attached to the steering wheel hub. In another embodiment, Fig. 4 (not shown) tube 45 is omitted and the end 47 of tube 42 is attached directly to the steering mechanism. Alternatively, both tubes 34, 45 are omitted and tubes 40 and 42 are attached respectively to the wheel 10 and steering mechanism. A speedometer 66, Fig. 6 is positioned above an instrument panel 13 instead of behind the steering wheel 10 so as to be in the drivers view without obstructing forward vision.

Title: Method and apparatus for the automatic regulation of the air ratio in combustion
IPC: F23N1/02
Filed: 1975-12-19
Abstract: 1534288 Automatic control of fuel/air ratio in IC engines BROWN BOVERI & CIE AG 19 Dec 1975 [19 Dec 1974] 52151/75 Heading G3R A control system for the air/fuel mixture supplied to a combustion chamber includes means to change the constituents of the hot exhaust products before their oxygen content is sensed whereby the control system alters the air/fuel ratio of the supplied mixture until the sensed quantity reaches a desired value. In the arrangement shown in Fig. 4, the burners 38 of a boiler are controlled by a controller 2 which is responsive to the oxygen content of a sample of exhaust gases 18 passing through tube 11. An electrolytic unit 5 is used to produce an oxidizing and reducing gas which selectively can be fed by valve 31 into the tube 18 to mix with the exhaust gas. By supplying additional oxygen the probe will provide a signal to cause the amount of air supplied for combustion to be reduced. Alternatively if hydrogen is added the sensed oxygen content will correspond to a weak combustion mixture and the supplied air/fuel mixture will be made richer. The reference signal for the probe by design corresponds to the oxygen content of the exhaust gases resulting from combustion of a mixture having #=1 and the arrangement described is used for continuous operation witb # # 1. For an I.C. engine the quantity of auxiliary gas  added is controlled by an engine operating parameter e.g. speed or temperature and the control may be applied to a carburetter or fuel injection arrangement, Fig. 1 (not shown). The exhaust gas mixing and sensing element is described, Fig. 2 (not shown) as consisting of a cell including a mixing (catalytic) section and a solid electrolyte oxygen sensor and includes a heater to ensure that the cell temperature exceeds 300‹C. In the cell shown in Fig. 3 the sample of exhaust gas enters at 11 and passes through a solid electrolyte cell which extracts or adds oxygen to the gas as determined by the strength and polarity of the current through screen electrodes 39, 40. The changed gas then has its oxygen content sensed by means of the electrodes 1 before it is exhausted through valve 19.
