Title: Actuating apparatus for the wheel brakes of a hydraulic braking system
IPC: B60T13/14
Filed: 1984-04-18
Abstract: The invention is based on an actuating apparatus for the wheel brakes (10, 11, 17, 18) of a hydraulic braking system for automotive vehicles with a master cylinder stepped bore (3, 2) which bounds both a pressure chamber (8, 15) associated with at least one wheel brake and a filling stage or quick-take-up chamber (22). Through a master cylinder sealing cup, hydraulic fluid is displaceable from the filling stage chamber (22) to the pressure chamber (15). The filling stage chamber (22), has a filling valve (24) which limits the maximum pressure in the filling stage chamber (22). In order to realise an assistance of the actuating force with the aid of servo hydraulic pressure, it is proposed that the stepped filling stage piston (7, 21) has a larger diameter part facing away from the pressure chamber (8, 15) and which bounds the servo pressure chamber (25) of a hydraulic power booster. Servo pressure is adjustable in the servo pressure chamber (25) independence on the actuating force exerted on the brake pedal (28). <IMAGE>

Title: Determining the ballistic trajectory of a projectile
Inventor: SUNDERMEYER DR PETER
IPC: F41G7/22
Filed: 1986-06-19
Abstract: A method for determining the ballistic flight path (23) of a projectile 21 that is to be fired from a weapon barrel 22 and which changes in a self-controlled manner from a ballistic firing flight path with linking flat flight path into an end-phase homing flight path removes the need for error-prone firing-data inputs into the projectile. For this, measurements are made on board the projectile of the muzzle velocity v1 of the projectile and of the time from firing (t1) up to passage through the apogee (t2). Additionally, by measuring the apogee, the build-up of a positional reference for the flight path control is made possible. Acceleration sensor 45, apogee detector 49 and exit sensors 41,42 provide signals t1, t2, t41 and t42 to a time measuring circuit 43, the measurements from which are translated into measurements of firing elevation angle w1 and propellant charge number # and fed to the store 38 for a navigation computer. <IMAGE>

Title: Dynamic range control of a signal
Inventor: MCNALLY GUY WILLIAM WHITSEY
IPC: H03G11/00
Filed: 1986-10-03
Abstract: A dynamic range controller consists of a multiplier 14, Fig. 1 controlled by a side chain 18 comprising: a level detector 20, a log circuit 22, a threshold subtractor 24, a non-linear circuit 26, a slope multiplier 28, and an antilog circuit 30. The level detector 20 comprises a peak detector (40, Fig. 4) with separate attack and decay time constants, in which the decay time constant is itself dependent upon the output of an r.m.s. detector (60). The slope and threshold values vary such that two or more different threshold/slope factor pairs are used for different sections of the signal amplitude so that the device provides different DRC functions (limiter, compressor, expander, or noise gate) for the different amplitude sections (Fig. 6). A smoothing recursive filter (Fig. 9) is included between the antilog circuit 30 and the multiplier 14, and has a time constant which varies as to whether the detector is in the attack or the recovery mode, this mode determination being made with a degree of hysteresis. The response time constant of the filter is about one-third of that of the level detector 20. <IMAGE>
