Title: Mechanical acceleration sensor for a seat belt pretensioner or an air bag system
Inventor: NISHIZAWA MUNEO
IPC: B60R22/46
Filed: 1994-01-24
Abstract: The sensor includes a casing 1, a weight 2, a spring-loaded firing pin 4, and a latch lever 3. The weight, the firing pin, and the latch lever each are movably mounted in the sensor casing in such a manner as to either translate along an axis, such as F and G, or to rotate about an axis, such as P and Q. The axes of translation are substantially perpendicular to that the axes of rotation. The latch lever 3 is loaded with a set load to engage the firing pin 4, and is positioned to be engaged by the weight 2 upon inertial movement of the weight in an emergency situation to disengage from the firing pin, thereby allowing the firing pin to perform a percussive firing action by the spring load. The casing 1 has an opening 18 for receiving the weight, firing pin and latch lever during assembly. Moreover, shaft support grooves 13 are provided in the casing such that each shaft support groove is open at an end thereof which faces the opening. Thus a shaft, such as 30 and 50, for a member that rotates is readily supported by the shaft support grooves during assembly. <IMAGE>

Title: Drying malt
Inventor: NALLEN THOMAS
IPC: F26B21/12
Filed: 1994-04-19
Abstract: A humidity detector 10 is used to continuously detect on line the humidity of air which has passed through a bed of germinated barley 2 in a kiln 1. A transducer 11 provides a signal to a fan speed controller 15 for modulating the flow of air drawn through the bed by a fan 6, at least during a "force drying" phase in which after moisture in the outer layers of the barley grains has been removed heated air moves moisture from the interiors of the grains to their surfaces. Preferably humidity is also monitored in an initial "free drying" phase in which heated air removes moisture from the surface layers of the grains and in a final curing stage in which air is passed through the bed 2 after drying is complete. <IMAGE>

Title: Optical disk rotational speed control
Inventor: SHIM JAE-SEONG
IPC: G11B19/28
Filed: 1994-04-20
Abstract: A system for controlling the rotational speed of an optical disc having pre-grooves providing wobble signals wherein a first rotational control signal is generated at 103 and 104 by comparing the phase of the wobble signal with a reference signal at 102 and a second rotational control signal is generated at 109 and 110 to accelerate or deceleratethe disc in accordance with a comparison of the pulse width of the wobble signal with that of the reference signal at 108. The first control signal provides precise control by phase comparison and is replaced by the second signal in the event of an abnormality eg a shock to provide rough speed control when such phase control is prevented. The abnormality is detected as a demodulation error at 111. Also disclosed is a system wherein a third control signal (123, figure 3) is generated in accordance with the deviation of the wobble frequency from a centre frequency with the rotation of the optical disc being controlled by summing the first and third signals. These two systems can be combined (see figure 10) so as to produce a disc rotation control system wherein the first control signal can either be combined with the third control signal or substituted by the second signal when an abnormality is detected. <IMAGE>

Title: PLL control of pulse width modulation
Inventor: WILSON COLIN JOHN
IPC: H03L7/06
Filed: 1994-11-02
Abstract: The control arrangement comprises a circuit for generating a nominally constant off-time pwm drive signal from an inputted pwm source signal, a phase comparator for comparing the phase of the inputted pwm source signal with the phase of a signal in said nominally constant off-time circuit; output of the phase comparator is connected to a control input of a generator of said constant off-time circuit to vary the pulse duration of the generator in order to lock the phase of an output signal of the generator with a predetermined point in each cycle of the pwm source signal. In the PWM drive circuit, an integrated output of the PWM source signal at G is compared with the voltage across source resistor Rs for turning a latch off which is turned on again after a fixed duration via a monostable circuit. The duration of this monostable period is controllable via the phase locked loop to ensure synchronisation of the PWM drive signal with the PWM source signal. <IMAGE>

Title: Method for separating a petroleum containing emulsion
Inventor: CHEN JAMES C T
IPC: C10G31/09
Filed: 1995-04-27
Abstract: The invention relates to a method of separating a multiple phase liquid medium comprising a first liquid phase and a second liquid phase wherein the medium is contacted with a first filter, said filter having been wetted by a wetting agent miscible with the first liquid phase but immiscible with the second liquid phase; whereby the first liquid phase passes through the filter, thus obtaining a filtrate substantially free of the second liquid phase. In a preferred embodiment, separation of a multiple phase liquid medium comprising liquid fossil fuel, water and biocatalyst employing one or two filters is disclosed. One filter will preferentially collect either the liquid fossil fuel or aqueous phase as the filtrate. The retentate will then flow to the second filter which will collect the component not removed before, i.e. the aqueous phase or liquid fossil fuel, as the filtrate. The remaining retentate, containing the biocatalyst, can then, preferably, be recycled. The process can be used to resolve an emulsion or microemulsion of the liquid fossil fuel and aqueous phase resulting from a BDS process. Also described is a method for controlling the reaction parameters of a mixed phase reaction process.

Title: Selecting and setting new matching relations for actuator control in a power construction vehicle
Inventor: LEE JIN HAN
IPC: E02F9/26
Filed: 1996-12-11
Abstract: A device for selecting a control mode in a power construction vehicle having proportional control valves has a control mode select switch which selects a function for setting new matching relations between the control levers and the proportional control valves. A controller sets and stores the new matching relations, and controls the actuators in accordance with the new matching relations. In the control mode selection method, one operational motion of an actuator is primarily selected and displayed on a display means. Thereafter, a voltage signal indicative of a levering angle of a control lever associated with the selected actuator is output, thus setting a new matching relation between the control lever and an associated proportional control valve. The above process is repeated in order to continuously set and store new matching relations between the control levers and proportional control valves associated with the other actuators.
