Patent EP-0436773-A2 (EP)
Inventor: CARIS JOHN R
IPC: B01D17/00
Filed: 1990-05-09
Abstract: A process for separating emulsified, suspended and separate oil as well as other contaminants from the water phase of a compressed air system condensate comprises the steps of discharging air and condensate from a compressed air system into a water filled separation tank (12,28) where air is separated from the condensate. Some of the contaminants heavier than water are allowed to settle to the bottom of the separation tank (28) while lighter oil contaminants are allowed to float to the surface where they are removed. Water and the remaining contaminants which did not flow to the surface or settle to the bottom of the tank are drained away until a given amount of liquid mass has been accumulated. Pressure applied to the liquid mass forces the mass into and through an underwater coalescing media (14,26). Such action causes substantially all of the remaining oil constituents to coalesce and thereby form a floating oil phase while other contaminants are retained by the coalescing media. The floating oil phase is removed and the remaining water is relatively pure.

Abstract: 2.1. In such circuit breakers, it is necessary to transmit the movement of a trip device by means of an intermediate element onto a locking point of the circuit breaker mechanism. In this arrangement, an adjustment capability must be provided in the transmission path for matching the trip device functions. The invention provides an adjusting device which is of simple construction and is non-interacting. 2.2. For this purpose, a trip lever (3), which can be rotated by a trip device (4), is arranged eccentrically such that it can pivot on an adjustable bearing body (2). By adjustment of the toothed bearing body (2), which is preferably arranged on the circumference side, by means of an adjusting tool (7), the trip lever (3), which acts on a latching pin (5) of the switch mechanism, can be set to predetermined nominal value functions. 2.3. The arrangement is especially suitable as an adjusting device for the thermal trip device of a power circuit breaker. <IMAGE>

Abstract: In this method, the radio receiver of the vehicle receives a sequence of equidistant radio signals from a stationary radio transmitter. For better utilisation of the elaborate infrastructure of such systems, a radio receiver is to be provided which can fulfil other functions without intervention in the infrastructure. For this purpose, it is proposed that the radio receiver is moved from a first operating site to a second operating site, a time measurement having been started, and the difference of the radio signal transit times from the radio transmitter to the two operating sites is measured. The transit time difference measurement enables the radio receiver to provide information on its change in location. Several such measurements allow it to determine the co-ordinates of the operating sites and thus of its position. A preferred field of use are car radio telephones, particularly in the digital D-network.

Inventor: BELL BERNARD W JR
IPC: G11B7/00
Filed: 1991-09-27
Abstract: When doing multitrack seek or a single track jump, the midpoint between the maximum and the minimum of the tracking error signal is determined. A peak detector (31) detects the positive peak and the negative peak. These maximum and minimum values are stored in a sample and hold circuit (32). A summing circuit (33) determines the midpoint between the maximum and the minimum of the tracking error signal. An operational amplifier (35) provides a true error signal to the servo control system (14) that provides the appropriate servo operating point. The invention is based on the fact that even though there is no absolute reference signal indicating the appropriate on-track position, the tracking servo system (14) obtains the track error signal over the whole range of positions relative to track center when doing a multitrack seek or a single track jump. The appropriate servo operating point is the midpoint between the maximum and the minimum of the track error signal. This provides compensation for level shifts due to factors such as beam displacement, or detector mispositioning, changes in read/write beam profile, and disk tilt. The present invention solves the key disadvantage of the continuous groove tracking method by eliminating tracking offsets without adding additional information to the disk. It also avoids imposing overhead on the data channel. It compensates for effects of disk tilt, detector misalignment, detector and amplifier offsets, and beam decentration due to fine tracking.

Abstract: A transfer molded plastic package having a cavity for accommodating a semiconductor chip is disclosed. A leadframe assembly process is shown wherein the leadframe finger pattern (13) is provided with a resilient or elastic O-ring bead (15,15'). Top and bottom housing plates (11,14) which have dimensions that are larger than the bead form the upper and lower surfaces of the package. These plates can be formed of any suitably rigid material. The chip or chips are connected to the lead frame and, along with the top and bottom plates, is located in a transfer mold. The mold cavities include faces which press against the plates which are held apart by the O-ring bead so that the bead is compressed by the mold closure. A plastic encapsulant (12) is molded around the periphery of the plates so that the leadframe fingers are secured therein to become package pins. The mold faces being pressed against the two plates precludes encapsulant from their faces which then become the outer faces of the package. The O-ring bead precludes the encapsulant from coming into contact with the semiconductor chip during the molding operation thereby creating a cavity package.

Abstract: The invention relates to a nuclear magnetic resonance spectroscopy procedure in which a sequence acts - preferably several times - on an area of examination, which sequence comprises two frequency-selective radio-frequency pulses which do not excite the water component and between which a 180 DEG  radio-frequency pulse is located. Such a sequence can be made more insensitive to imperfections of the 180 DEG  pulse by the second frequency-selective radio-frequency pulse being followed by a further frequency-selective radio-frequency pulse which does not excite the water component and by a magnetic gradient field being switched on and off between the second frequency-selective radio- frequency pulse and the further radio-frequency pulse, and after the further radio-frequency pulse, in such a manner that the time integrals over this gradient field are identical to one another before and after the further radio-frequency pulse.

Abstract: An electronic circuit for measuring a short time interval which is present in the form of an electric measurement pulse comprises a ring oscillator (OSC) which consists of a chain of series-connected inverters (I3 - I16). A controllable element consisting of NAND gates (NA) and two additional inverters (I1, I2) switches the ring oscillator (OSC) on and off. The full clock periods of the latter are counted in a first pulse counter (C1) and a second pulse counter (C2). A phase indicator consisting of memory chain (SPK) and evaluating logic (LOG) registers the phase angle of the last clock period of the ring oscillator (OSC) at the instance of switching-off. An arithmetic logic unit (ALU) uses the registered phase angle to decide which of the two pulse counters (C1) or (C2) contains the correct count and calculates from the selected count and the registered phase angle the length of the measurement pulse with an accuracy corresponding to the transit time of one inverter. The proposed circuit is distinguished by extremely high measuring accuracy within a range of 200 picoseconds and can be inexpensively implemented in a single integrated CMOS circuit. <IMAGE>
