Patent EP-0348758-A2 (EP)
Inventor: TAL RONY
IPC: H04Q9/00
Filed: 1989-06-16
Abstract: An industrial automation system using transformers for providing electrical isolation between a system interface chip and a load interface chip while simultaneously allowing communication of power and data across the isolation barrier. Clock pulses are transmitted from the system interface chip to the load interface chip across one transformer, and the clock pulses are used by the load interface chip to create a power supply for operating the components within the chip. Data is communicated from the system interface chip to the load interface chip across a second transformer by the use of messages. Each message comprises a bit sync field, a byte sync field, and a data field. The bit sync field and byte sync field are used by the load interface chip to synchronize itself with the system interface chip. Transmission and reception of data by the chips are interleaved on a bit-by-bit basis, wherein a bit is transmitted from the load interface chip to the system interface chip after each bit is transmitted from the system interface chip to the load interface chip. After each byte of data is transmitted and received by the chips, the load interface chip eliminates synchronization between the chips, and must resynchronize itself with the system interface chip in order to transmit and receive the next byte of data.

Abstract: An electrically controlled auxiliary hydraulic system (60) for both front and rear mounted attachments on a skid steer loader. An electrically actuated auxiliary control valve (92) is coupled to the front and rear mounted attachments through an electrically actuated diverter valve (74). An operator can select between control of either the front or rear attachments by actuating a diverter switch located on a steering lever. The auxiliary control valve (92) is then used to control the selected attachment by actuating forward, reverse and forward latch switches on the control handles. The selected attachment can also be operated in a high pressure mode by actuating a high pressure switch when extra horsepower needs to be delivered to the attachment.

Abstract: A sample preparation process and apparatus are provided for samples to be analyzed subsequently, such as by liquid chromatography. The sample is passed in contact with an ion exchange polymer which is characterized by being capable of facilitating removal of one or more undesired ions from the sample to be replaced with an ion transferred from the bound exchange site of the polymer and through the polymer. The polymer is prewashed with water to remove substantially all leachable species from the polymer. In one embodiment, the polymer is coated with a color indicator capable of changing color when the polymer is depleted of the ion to be transferred therefrom. The ion exchange capacity of the apparatus can be significantly expanded by using a counter ion donating solution capable of replacing the bound ions at the ion exchange sites as they become exchanged for the undesired ions from the sample.

Abstract: The invention relates to integrated compression amplifiers which can be constructed in CMOS technology and the threshold voltage of which is programmable. The compression amplifiers specified can be installed in a multi-channel AGC device so that the circuit can also be integrated on a "switched capacitor" filter chip in CMOS technology. Essentially, the compression amplifier circuits are a feedback-type amplifier the gain of which is controlled by the output amplitude. For this purpose, an amplifier SC with variable gain, constructed as "switched-capacitor" amplifier, a rectifier stage GR' and a low-pass filter TP' are present in the feedback branch and a two-quadrant multiplier ZM' must be connected between input and output Ue', Ua'. In this arrangement, the output of the low-pass filter TP' is fed back to the control input of the two-quadrant multiplier ZM'.

Abstract: The invention relates to an extrusion or press die which is used in the production of ceramic or plastic products and comprises a flange cylinder (2) and a presshead (1), which bound a cavity (3). The material to be processed is conveyed into the cavity (3) by means of a screw (9) and forced through the presshead (1). For sensing the pressure in the cavity (3), the invention provides for the flange cylinder (2) and the presshead (1) to be arranged such that they are to a limited extent displaceable with respect to each other in the axial direction and for them to be pressed against each other by means of a resilient clamping device. Arranged on the clamping device is a pressure sensor (24), which senses the relative axial displacement between presshead (1) and flange cylinder (2), from which the pressure prevailing in the cavity (3) can be derived. This pressure signal is extremely accurate. <IMAGE>

Abstract: At least one control valve which has a control spool which is spring-loaded on one side and can be deflected against the spring force by a servomotor is used for controlling a hydraulic cylinder having a double-acting working piston. In the novel control system, at least one control valve each, belonging to each pressure space (16, 16a) of the hydraulic cylinder (15), is provided in a one-piece or multi-piece valve housing (1). The control spools (2, 2a) of the control valves are arranged coaxially and in mirror image to one another at a mutual distance apart. Here, a common control element (19, 20) of the servomotor (17), which control element (19, 20) is located between the inner ends of the control spools (2, 2a), serves to move the two control spools (2, 2a) in the same direction. Furthermore, each control spool (2, 2a) contains one auxiliary piston (8, 8a) each in one pressure space (26, 26a) each, in which arrangement the pressure spaces (26, 26a) can be acted upon via a manipulating valve (24) and the control spools (2, 2a) can thereby be moved into an inactive position in which they are removed from the effect of the control element (19, 20) of the servomotor (17). This inactive position can be activated directly as an "emergency stop function" from every operating position of the control spools (2, 2a). In addition, in the inactive position, the servomotor (17) can be moved into its zero or centre position and be orientated without this involving movements of the piston of the hydraulic cylinder (15). …<IMAGE>…

Abstract: A heterogeneous interpenetrating polymer network is provided for use in the controlled release of drugs. The network is a heterogeneous matrix that is formed from a hydrophilic component such as polyethylene oxide or poly(N,N′-dimethyl acrylamide-co-styrene) and a hydrophobic component such as styrene, an alkyl methacrylate, or polytetramethylene ether glycol. The relative amounts of the two components, or "domains" can be varied, as can the diffusivities and solubilities of the drug combinations to be loaded therein, to control and change as desired the timed release profile of incorporated drug. Prolonged pseudo-zero order release can be obtained where one domain acts as a diffusion barrier layer to the release of drug from the other domain.

Abstract: A main memory control system has an initial data generating circuit for generating initial data, an initialization control circuit for activating an initialize signal in response to an initialize command, and a refresh control circuit that generates refresh addresses. When the initialize signal is inactive, the main memory control system performs normal read, write, and refresh operations. When the initialize signal is active, the main memory control system selects the initial data by means of a data multiplexer and performs only write operations, writing the initial data at refresh addresses generated by the refresh control circuit. If the main memory has an interleaved structure, the initial data are written in all leaves simultaneously.

Abstract: A cavity-backed dual-slot antenna element for circular polarisation having a single probe (14) extending from the end of the feed line (13) for the element and arranged to couple energy into the resonant slots (15). The probe (14) lies in the plane of the feed line (13) and has the form of an open circle having a circumference of approximately one wavelength at the operative frequency. The probe (14) is constrained to lie within the boundary (17) of the resonant slots (15) as projected onto the plane of the feed line. The arrangement produces a circular polarisation having a greater axial-ratio bandwidth than that of conventional antennas using two orthogonal probes or using a single probe feeding a resonant patch. An antenna comprising a flat array of the elements is suitable for use in DBS (Direct Broadcast by Satellite) TV reception. However, the probe itself is not limited to use in slot antennas and it has applications in other antennas or couplers for circular polarisation.
