Abstract: Image processing apparatus for increasing the gray scale resolution of a graphic generated by an ink jet printing system wherein the graphic is made up of pixel areas on a receiving surface and each pixel area is comprised of a fixed number of potential dot positions printed with substantially equal sized dots. A sequential series of image density signals representative of the grey scale color intensity is generated from an original graphic and converted to a dot level value for each pixel. A pixel's dot level value is compared to a set of integer and non-integer values and pixels having dot levels falling between the same two sucessive integer values are selected. A predetermined dot level value is alternately added to the identified adjacent pixels so that one is increased and the other is decreased by the predetermined dot value. The resulting values are rounded off to the nearest integer and each pixel is printed with its respective new value. The resulting gray scale color intensity represented by the two printed pixels is the average of the sums of the two printed pixels' dot level values.

Title: Hydraulic brake system for rail vehicles
Inventor: ROGER MICHEL
IPC: B60T13/68
Filed: 1986-04-21
Granted: 1989-06-01
Abstract: A hydraulic brake system for vehicles, particularly light rail vehicles, includes at least one brake actuator for engaging the brake by means of a group of springs and disengaging the brake by hydraulic pressure. The system comprises an electric drive motor and pump for supplying pressurized hydraulic fluid to the actuator, and a safety valve and solenoid valves for controlling the pressure of the hydraulic fluid in the actuator. An accumulator is connected to the electric drive motor and pump for delivering the pressurized hydraulic fluid via valves and restriction for adjusting the pressure in the accumulator to a value substantially inversely proportional to the load of the vehicle. It is connected to the actuator by shuttle valves controlled by the pressure of the accumulator when the control safety valve and solenoid valves are actuated to relieve hydraulic fluid from the actuator.

Abstract: A method and apparatus for monitoring the physical and chemical properties of a sample fluid by measuring an optical signal generated by a fluorescent substance and modulated by an absorber substance. The emission band of the fluorescent substance overlaps the absorption band of the absorber substance, and the degree of overlap is dependent on the physical and chemical properties of the sample fluid. The fluorescent substance and absorber substance are immobilized on a substrate so that an effective number of molecules thereof are sufficiently close for resonant energy transfer to occur, thereby providing highly efficient modulation of the fluorescent emissions of the fluorescent substance by the absorber substance.

Title: Pneumatic distributor of the duplex type for motor vehicle braking systems
IPC: B60T15/04
Filed: 1987-03-31
Granted: 1989-06-22
Abstract: The distributor includes a body (2) with first and second inlet connectors (10, 11) for connection to two pressure sources, and first and second outlet connectors (12, 13) for connection to two separate brake circuits. Communication between the inlet connectors (10, 11) and the outlet connectors (12, 13; is controlled by two valves (15, 16; 19, 20) formed coaxially in the body (2) and provided with a common control device. This device comprises first and second pistons (5, 23) movable coaxially in the body to control the first and second valves. The first piston (5) is movable by means of the operation of the brake pedal and has an extension (26) which extends through an aperture (25) in the second (23). The latter has an associated spring (24) which biasses it towards the position in which it opens the second valve (19, 20). First and second reaction members (27, 28) are movable on the extension (26) of the first piston (5), the first of these cooperating with the second piston (23) and the second being located between the first reaction member (27) and an end retaining head (26a) of the extension (26). Between the reaction members is a spring (29) which urges the first of these towards the first piston (5) and the second against the retaining head (26a). A stop member (30) is provided in the body (2) for stopping the second reaction member (28) relativ to the extension (26) of the first piston (5) when the latter is close to the position in which it causes the opening of the first valve (15, 16), so that further movement of the first piston (5) causes compression of the spring (29) between the reaction members (27, 28). This spring (29) is therefore not compressed in the initial operating phase of the brake pedal and hence does not provide any reaction to the foot. This spring is compressed only when the opening of the valves (15, 16; 19, 20) is imminent and the consequent reaction transmitted to the foot of the driver is an advantageous indication of the imminence of the opening of the valves.

Date May 19, 1988.In a method for feeding out the primary web of a mineral wool web by means of a pendulum conveyor and to an arrangement of such a pendulum conveyor, an output is fed as close to the receiving conveyor as possible for the primary web to be rapidly fixed onto the underlying web. The conducting rollers at the output end, which rotate in the output direction, have a disturbing effect on such a close output. The front conducting roller in the direction of motion rotates in a direction having a lifting effect on the underlying web, which is negative, whereas the rear conducting roller rotates in a direction pressing down the web being fed out, which is advantageous for the output. Both conveyors of the pendulum conveyor are made vertically movable with regard to each other, the front conducting roller being situated higher and the rear conducting roller lower during the pendulum swing. The reversing mainly takes place in the end position of the pendulum swing. The reversing may take place momentarily or gradually during the entire pendulum motion.

Abstract: Apparatus for detecting the presence of an object within an area under surveillance employs an electro-optical emitter for directing light into the area and an electro-optical receiver for sensing light reflected from the object which originates from the emitter. The emitter emits light energy of a preselected wavelength and is modulated at a preselected frequency to provide the emanating light energy with a characteristic signature. Light reflected by an object within the area under surveillance is filtered and converted to an electrical signal which varies in accordance with the magnitude of the filtered light having the preselected wavelength and modulation frequency. A selected portion of the electrical signal is amplified by a band-pass amplifier and is synchronously sampled in accordance with the modulation frequency to determine the magnitude of the filtered light which originated from the emitter. The sampled signal is compared with a threshold value to determine whether an object is present within the area under surveillance. The emitter and receiver are covered by a transparent shield to protect them against foreign matter. An electro-optical detector monitors the accumulation of foreign particulates on the shield. The apparatus may be desirably used in vehicles to detect the presence of adjacent objects, particularly within the vehicle's "blind spots" and thereby avoid collisions.
