Title: Fluid pressure operable servomotor
IPC: B62D5/24
Filed: 1976-01-08
Abstract: 1504221 Power steering systems DAIMLERBENZ AG 8 Jan 1976 [17 Jan 1975] 00645/76 Heading B7H A power steering system including a working piston 45 with differential surfaces 98, 99 respectively arranged in chambers 48, 49 and a piston 59 concentric with and axially movable relative to the piston 45 effective to increase or decrease the surface area 98 to aid return motion after steering action. Piston 59 is slidably mounted on a sleeve 61 about the steering spindle 17 and is provided with equal end surfaces 100, 101. In the neutral, or straight ahead steering position, the piston 59 rests against a stop ring 65 and via surface 101 against guide piston 30 which is screwed to the working piston 45. Chamber 49 is connected via lines 70, 71 to a high pressure accumulator and a sliding spool valve 76 operated by an arm 79 on nut 28 within the guide piston. Chamber 48 is connected by valve 76 to accumulator pressure or exhaust via line 73. When in the neutral position the total surface area of pistons 45 and 59 is acted on by pressure in chamber 48 and this is balanced by the pressure in chamber 49 acting on surface 99. To move piston 45 to the right excess pressure is supplied via valve 76 to chamber 48 and this acts on only piston 45 since piston 59 is fixed against rightward movement by stop 65 on axially fixed sleeve 61. During return movement only area 98 of piston 45 is effective to resist return, this area being less than that effective when the piston is in the neutral position. On movement of the piston to the left by reduction of pressure in chamber 48 the effective area of pistons 45 and 59 is greater than the effective area in the neutral position. During return action, with surface 101 of piston 59 against the guide piston but the piston 59 being clear of stop 65, the greater area acts to return the piston. The control valve 76 includes reaction pistons of different areas for improved feel.

Filed: 1935-01-09
Abstract: 440,981. Sub-station equipment; recording and reproducing music &c. LABORATORIES DE RADIOTECHNIE SOC. ANON., 77, Rue de Prony, Paris. Jan. 9, 1935, Nos. 759 and 762. Convention dates, Jan. 9, 1934 and Feb. 2, 1934. [Class 40 (iv)] [See also Group XL] In combination apparatus for wireless reception, two-way line telephony, recording wireless, telephonic and local transmissions and reproducing therefrom, the switching arrangements are such that the input to a detecting and amplifying valve is connected to the grid in the case of wireless reception and record reproducing whereas the input is connected to the cathode in the case of the telephone line or a local microphone. Couplings due to the circuitcontrolling switches are thereby minimized. A multi-grid valve may also be used with the various sources connected to different grids. The switching is effected by the two-way switches shown in the dotted rectangle. For wireless reception, the contacts 11, 20 ; 8, 15 are closed to complete the input circuit from high or intermediate frequency transformer 1 to the grid of valve 2 and the loud-speaker circuit, and if it is desired to record, contacts 10, 18 are also closed to connect up a combined recording and pick-up instrument 5 a filter circuit 40 being introduced when 5 is used as a recorder. Reproducing from records is effected by closing 11, 21 ; 8, 15 the input again being taken to the grid of valve 2 but the filter 40 is not used. To record a local source, the primary microphone circuit 4 is closed at 12, 23 ; the secondary of the microphone transformer is connected at 9, 16 across a bias resistance 50 in the cathode circuit of the valve, and the recording instrument 5 with filter is connected at 10, 18. Two-way loud-speaker telephony is effected over line 6 by closing 13, 25 ; 9, 17 ; 8, 15; 11, 20 ; and 12, 23, the resistance of the microphone transformer being high relatively to the line to avoid effects due to acoustic reaction.

Title: Control means for fuel injection pumps for internal combustion engines
Inventor: MORRIS JOHN NEVILLE
IPC: F02M69/00
Filed: 1964-01-09
Abstract: 1,025,009. Fluid pressure servomotor systems. S. U. CARBURETTER CO. Ltd. Nov. 19, 1964 [Jan. 9,1964], No. 979/64. Heading G3P. [Also in Division F1] In an improvement in the control means described in Specification 989, 983 the fuel per cycle delivery of the fuel injection pump is modulated, in response to a unit change in engine coolant temperature or atmospheric pressure, to an extent proportional to its value i.e. by a constant percentage. The longitudinal position of cam 23 is controlled by governor 35, Fig. 2 (not shown), and the rotational position is controlled by the throttle 32 which is connected by the link 34 to the accelerator pedal. Movements of cam follower 22 alter the force applied by a spring 20 to a plate 26 which acts through a spindle 13 on a valve plate 10. Capsules 27, which are acted on by atmospheric pressure and are subject to engine coolant temperature changes, vary the force applied by spring 20. Pressurized fuel enters ducts 7 and moves piston 6 against spring 9. Fuel passes through hollow spindle 12 and orifice 11 past valve plate 10 and through orifice 11 to a reservoir from where it is returned to duct 7. Piston 6 takes up a position corresponding to the force applied by spindle 13 and acts through sector 16, push-pull cable 18 and sector 17 on the regulating spindle 2 of a variable delivery fuel injection pump 1. The eccentric mounting of sectors 16 and 17 causes a change in the velocity-ratio between movement of piston 6 and rotation of spindle 2 which varies between maximum and minimum the fuel delivery conditions. In a modification the modulation of fuel delivery is obtained by substitution of a variable-rate spring for spring 1. Reference has been directed by the Comptroller to Specification 989, 983.
