Patent EP-0273465-A2 (EP)
Inventor: DE LEEUW DAGOBERT MICHEL
IPC: H01J31/10
Filed: 1987-09-29
Abstract: Phosphors used in colour cathode ray tubes, particularly but not exclusively, projection television tubes, should have colour point standards or chromaticities conforming to European Broadcasting Union (EBU) standards. The widely used blue light emitting cathode ray tube ZnS : Ag phosphor which conforms to EBU standards has the disadvantage that its efficiency at high beam currents is low and in consequence limits the white-D luminance of projection television systems. 
     Many blue light emitting phosphors exist which are more efficient than ZnS : Ag at high beam currents but which have the disadvantage that their chromaticities do not conform to EBU standards because the y-value in the CIE colour triangle is too high or too low. This disadvantage can be overcome by disposing an interference filter which has a peak gain greater than unity over a selected part of the frequency spectrum in the light-path from the phosphor for example between the phosphor and the faceplate. As a result of using an interference filter an efficient broadband phosphor can be employed to obtain the desired chromaticity and thereby increases the white-D luminance of projection television systems.

Abstract: A pellet for administration to ruminants to supply magnesium and other biologically active material, for example, anthelmintics or antibiotics comrpises a tube of magnesium alloy (1) enclosing a core or filling (3). The core (3) typically comprises mainly iron shot as weighting material, a biologically active material if desired and an electrically conductive material such as carbon or graphite. The graphite ensures that the core (3) as a whole is conductive and provides a cathode electrically coupled with the magnesium alloy tube (1) to form a galvanic cell. Liquor in the rumen serves as an electrolyte to cause galvanic corrosion of the magnesium tube (1) to release the active material contained in the core (3). A protective coating (5) of resin is provided on the tube's exterior surface except on at least one end (4) so that the corrosion is limited to the exposed surfaces only. An alternative embodiment (Fig. 4) comprises a control magnesium alloy rod or shaft (11) around which a cylinder (13) of the electrically conductive component is pressed. The cylinder contain iron shot and graphite in similar proportions to the core (3) in the first embodiment and is also provided with a protective resin coating (12) to restrict corrosion to one or both ends of the rod (11).

Abstract: 1. Apparatus for signal transmission from a rotating element to an element which is stationary with respect to the rotating element, particularly from a wheel of a vehicle to the vehicle. 2.1 In known devices, a toothed ring which rotates with the vehicle wheel is scanned by a sensor and a first sensor signal corresponding to the speed of the vehicle wheel is generated. A second sensor signal is generated by an adjustment element which consists of a ferromagnetic material and in the event of a display fills a tooth gap of the toothed ring so that a multiply widened tooth is simulated to the sensor as an element to be sensed. This second sensor signal is however only adequately distinctive and capable of being perceived in an error-free fashion by an evaluation electronic system when the tooth gap is completely filled by the adjustment element. The new device is intended to generate an improved second sensor signal in comparison with the known device. 2.2 The adjustment element (7) is formed by a permanent magnet whose cross-section is arranged in the region of the tooth edge (11) of a tooth (2) of the toothed ring (4). The magnetic field generated by the adjustment element (7) can be perceived by the sensor (5). 2.3 The device can be used inter alia on vehicle wheels in which a measuring device is used to detect the wheel speed in the manner of a toothed ring/sensor combination. <IMAGE>

Abstract: A gripping device for an apparatus for placing electronic and/or electrical components with terminal pins on a substrate comprises a pair of grippers (9 and 10) which are movable relative to one another by fluid-pressure operated means to close and open the jaws (12 and 13) of the grippers. The force for driving the pins of a component into the respective holes in the substrate is applied to the component through abutment means which are self-adjustable to accommodate differences in the heights of the components so that the gripper jaws can be brought to a constant level at the pick-up position each time and can be arranged to grip the component over areas which extend to the bottom of the body of the component to facilitate accurate positioning of the terminal pins in relation to the respective holes in the substrate when mounting the component. The abutment means comprise a spring-loaded, vertically disposed rod (18) which is movable vertically relative to the gripper jaws (12 and 13) and which abuts the upper side of the body of the component (16) as the gripping device is lowered to the pick-up position. As the gripper jaws close on the component a friction element (26) is moved to engage the side of the rod (18) to lock the rod in abutment with the component so that the rod can subsequently transmit the necessary force to the component to insert the terminal pins into the holes in the substrate. The friction element (26) is actuated by a piston (32) through a bell-crank lever (28), the piston being controlled by the valve means (not shown) which control the actuation of the grippers.

Abstract: There is disclosed herein an interface for a peripheral to allow the peripheral to communicate with either synchronous or asynchronous systems. The interface includes a series of flip-flops coupled in a chain to take the combined data strobe and chip select signals from an asynchronous system such as a microprocessor and synchronize the combined signal with the peripheral clock and convert the signal to a pulse. This pulse then emulates the instruction enable pulse received from synchronous microprogrammed systems. If the peripheral is operating in a synchronous system, the instruction enable signal from the system is gated through a multiplexer controlled by a mode signal which indicates which mode is active so as to act as the peripheral instruction enable signal. An AND gate gates one bit of the instruction bus with the ANDed chip select and data strobe signals to create a read/write control signal for interval use in controlling the data bus drivers.

Abstract: A bar code is printed with a transparent fluorescent ink or a transparent polymeric ink which is generally invisible. The bar code is read by emitting ultraviolet or infrared radiation to the bar code and by determining the difference in the intensity of a light reflected by the bar code which is caused by a different reflectivity of the bar code. In other words, the bar code printed with the invisible ink is made visible by emitting radiation with a particular wavelength thereto. In consequence, since the bar code is invisible in a normal state, there is no restrictions on the package design. Further, the length of a bar of the bar code can be made long, thereby greatly improving the reading accuracy.

Abstract: In a plural phase overload relay, a pivot lever (12) is mounted to the ambient compensator deflector (9), and a second pivot lever (34) is mounted to both driver and follower slide bars (36 and 38) and driven thereby to engage and pivot the first lever on the ambient compensator deflector to trip a cut-out switch. The ambient compensator deflector adjusts both the three phase current trip threshold and the loss of phase current trip threshold, and also affords ambient compensator of each. A constant ratio relationship between these two thresholds is provided throughout the entire range of current trip threshold settings. The driver bar moves a first distance for three phase trip and a second shorter distance for loss of phase trip. The ratio of these distances is constant notwithstanding adjustment by the ambient compensator deflector changing the length of such distances.
