Title: Method and apparatus for determining whether or not a main throttle mechanism of an internal combustion engine is bearing against a diaphragm type throttle valve actuator
Inventor: MISCH WOLFGANG
IPC: F02D41/24
Filed: 1985-06-07
Abstract: In a method (and an apparatus) a signal signifying whether or not a main throttle mechanism (7) is bearing against an electro- pneumatic diaphragm type throttle valve actuator (1) of an internal combustion engine is derived from the different pressures occurring in the working pressure vacuum chamber (4) of the throttle valve actuator. In order to avoid erroneous bearing condition signals (SL) due to pressure fluctuations and the different mechanical system hystereses occurring when the throttle mechanism comes into contact and leaves the actuator, a suitable switching threshold is used which may be varied, if necessary, as a function of the actual position of the actuator diaphragm (2). A differential pressure toggle action switch (Fig. 3) which may be located in the working pressure vacuum chamber comprises a curved conductive diaphragm (21) and a contact (27), the diaphragm being displaced to touch the contact under predetermined conditions. <IMAGE>

Title: Process for the preparation of waste paper
Inventor: KONECSNY HELMUT
IPC: D21B1/32
Filed: 1985-07-01
Abstract: Waste paper is pulped in a pulper 1 and then fed to a screening apparatus in which a sieve (6,8) which is substantially perpendicular to the rotor axis separates a circulating space from an accepts region which is sub- divided into two compartments (7 and 9) which correspond to areas of the sieve having holes of different sizes, so that two accepts streams are obtained. The hole diameters differ by at least 5 mm, the smaller holes being within the range 2 to 8 mm. The rejects fraction is discharged intermittently through valve 16. The coarser accepts fraction may be recycled to the screening apparatus while pulper 1 is being filled, so that the screening apparatus works almost continuously. Alternatively the coarser accepts is fed to a second screening apparatus. (Fig. 2 not shown). <IMAGE>

Patent GB-867867-A (GB)
Abstract: 867,867. Gyroscopic apparatus. SPERRY GYROSCOPE CO.. Ltd. Feb. 7, 1957, No. 4311/57. Drawings to Specification. Class 97(3) [Also in Group XXXIV] In a gyroscope having a rotor casing supported in mercury within an outer container, the rotor casing is centralised inside the container by a pump-maintained flow of mercury. In addition, rotation of the rotor casing about the axis of rotation of the rotor is prevented by a base, attached to the casing, and immersed in mercury circulated by the pump. Magnetic pick-offs supply error signals corresponding to the relative displacement of the casing and container. The surfaces of the rotor casing and container are prevented from contacting by spacers mounted on the container, to maintain the mercury filling of the interspace. The mercury flow passes from the pump, through passages in the container, to open chambers on the container inner surface. From the chambers mercury passes into the space between the container and rotor casing and back to the pump. Movement of the rotor casing towards one of the chambers, restricts mercury flow therefrom and the resultant local rise in pressure, at that chamber, urges the rotor casing back towards the central position. Specifications 817,570 and 867,868 are referred to.

Title: Engine idle speed control
Inventor: DEUTSCH ROBERT W
IPC: F02D41/16
Filed: 1987-06-05
Abstract: Idle speed control is enabled by means (50-56) when the actual engine speed (RPM) becomes substantially equal to the desired engine speed (DIDLE) and disabled when the actual engine speed (RPM) becomes greater than the desired engine speed (DIDLE) by move than a set amount (v1). A speed error signal (e) generates a control signal at (40) having proportional and integral components from stems (29-31) and (32-38) respectively. When the speed control is disabled, an integrator (33) stores the last value of the integral component for immediate use when the control is next enabled. A throttle closed signal from sensor (60) may also be needed to enable the idle speed control. The control signal generated at (40) is used to control an air bypass (28). A signal (TQPOL) may be generated to control the bypass (28) and a fuel control (80) during overrun. <IMAGE>

Patent GB-2226414-A (GB)
Title: Improvements relating to rotary encoders
Inventor: SLATTERY DANIEL T
IPC: G01P13/04
Filed: 1989-11-08
Abstract: For rendering the signals developed by a shaft encoder less susceptible to corruption by transmission noise the invention provides a signal processor within the shaft encoder which processes the raw signals from the shaft encoder transducers into a condition more suitable for transmission over relatively long distances. In one embodiment, a shaft encoder produces three discrete output pulse trains providing frequency and phase information representative of speed and direction of rotation and instantaneous position of a shaft, and the invention provides a signal processor which detects unique logical states existing across the three pulse trains and outputs a correspondingly pulse width modulated signal for transmission, advantageously via an optical fibre transmission line, to a receiver decoder. In another embodiment, the output pulse trains of the shaft encoder are processed under microprocessor control by a signal processor provided in the shaft encoder and an output data signal is developed in a format which is adapted for remote transmission and includes error checking and correcting facilities.
