Abstract: 1,178,138. Collapsible steering columns. TRW Inc. 3 June, 1967 [14 April, 1967], No. 25674/67. Heading B7H. In a collapsible steering column for a motor vehicle, upper and lower steering shaft parts 21, 30 are connected to telescope under a predetermined axial impact load, and a bracket attachable to the vehicle so supports the upper shaft part 21 as to impart a desired resistance to sliding of the upper shaft part relative to the bracket when the shaft parts telescope. The lower shaft part 30 is a hexagonal rod which extends with a small surrounding space into the hexagonal of a tube forming the upper part 21. A plastics filling in the space and in a transverse passage 31 forms a shear pin 33 connecting the shaft parts 21, 30. The upper shaft part 21 is journalled by bearings 19, 20 in a jacket tube 14 carried by the bracket 10. Progressive resistance to movement of the jacket tube 14 through the bracket 10 is provided by pins 50 carried by the bracket and arranged to enlarge preformed grooves in the jacket tube as the tube slides through the bracket. A ring 40 on the jacket tube 14 prevents upward displacement of the tube relative to the bracket 10, and a stop 43 on the upper shaft part 21 prevents upward displacement of the upper shaft part relative to the jacket tube.

Title: An improved apparatus for generating a mixture of combustion products and air under pressure
IPC: F02B33/22
Filed: 1925-10-21
Abstract: 241,918.. Johansson, J. E. Oct. 22, 1924, [Convention date]. Two- and four-stroke engines. - Combustion products under pressure are generated in a plant comprising an internal-combustion engine 7, one or more air compressors 8 driven by the engine, and a receiver 9, the products expanded in the engine being mixed therein with air from the compressor to prevent an excessively high temperature of the resulting mixture. The exhaust valve of the engine is opened mechanically at the end of the expansion stroke when the pressure of the expanded gas is approximately the same as that of the compressed air, the stroke volumes of the compressor and the engine being such that the total volume of air taken in by the plant is at least 50 per cent greater than that of the air used for charging the engine only. In one form, Fig. 1, the engine 7 works on a four-stroke cycle. Air from the compressor 8 passes to a receiver 12 and is further compressed in the rear end of the engine cylinder 7, from which it passes to a receiver 13. Air is admitted from the receiver 12 to the engine 7 by a valve c and compressed, fuel is injected through a valve 14 at the beginning of the power stroke, and on the exhaust stroke the products of combustion are expelled to the receiver 9 through a valve b and a pipe 15, together with air admitted to the engine by a valve a from the receiver 13. In a modification, the air to be compressed in the rear end of the cylinder 7 is taken directly from the atmosphere instead of from the receiver 12, and steam may be admitted to the pipe 15 to lower the pressure. In another form, the engine works on a two-stroke cycle, air being compressed at high pressure into a single receiver by the compressor 8 and the rear end of the engine cylinder which act as single-stage compressors. Six-stroke engines.-In a further form, the separate compressor 8 is omitted and the first stage of compression takes place in the combustion chamber of the engine 7, which works on a six-stroke cycle; the second stage takes place, as in Fig. 1, in the rear end of the engine cylinder.

A jet propulsion nozzle comprises a wall defining the nozzle outlet having an upstream end of circular configuration to conform with the jet pipe and progressively changing in the axial direction until, at the downstream or outlet end, it has the configuration of a succession, in the circumferential direction, of outwardly convex elastic sections, each having a curvature greater than that of the overall configuration of the outlet and alternating with outwardly concave sections; a succession, also in the circumferential direction, of channel section strakes which fit into the outwardly concave sections and conform to their shape and means for effecting simultaneous inward movements of the downstream ends of the strakes to vary the area of the nozzle, the outwardly concave sections being supported against flexing by the strakes. The nozzle comprises an elastic tubular metal sleeve 10 and six strakes 11. The sleeve 10 is of circular section at its upstream end which is attached to the jet pipe by a ring of flexible material. The strakes 11 which extend over the full length of the sleeve 10 are of channel section of which the width and depth both increase progressively from the inlet to the outlet end. At the outlet end, the base of each strake is nearly semicircular as shown at 11a, Fig. 2. The several strakes converge inwardly and impart to the outlet of the sleeve the scalloped formation shown in Fig. 2 in which six outwardly convex sections 10a alternate with six outwardly concave sections 10b. The strakes are stiffened by cross-bars 16 of aerofoil cross-section. Each strake is pivoted to the jet pipe by a pin 22 and carries at the end of an extension 17 a roller 28 which engages a cam 29. The cams are carried by a ring 30 which moves circumferentially around the pipe on rollers 31 running in a guide channel 32. The ring 30 is actuated by an hydraulic ram to rock the strakes outwardly so that the portions 11 move inwardly and reduce the area of the nozzle. As shown, the sleeve 10 is of unitary construction but may be made in sections 10a, 10b which are secured to the strakes. The Provisional Specification describes also an arrangement in which the strakes are actuated by toggle links attached to an annular member surrounding the nozzle. An arrangement in which two concentric variable area orifices are provided is also described in the Provisional Specification.
