Title: High resolution gamma ray detectors for positron emission tomography (pet) and single photon emission computed tomography (spect)
Inventor: FENYVES ERVIN J
IPC: G01T1/20
Filed: 1990-11-09
Granted: 1993-12-02
Abstract: A device and method for detecting gamma rays in a diagnostic imaging system preferably utilizing fast step index scintillating fibers and photomultipliers is provided by the present invention. A plurality of scintillating fibers are formed into layers comprising substantially parallel fibers positioned lengthwise each other in each layer. Each layer is positioned parallel each adjacent layer with each layer having its respective fibers at an angle of substantially either 60 DEG  or 90 DEG  to each adjacent layer. Preferably, position sensitive photomultipliers are provided and each photomultiplier is coupled to a plurality of fibers and each fiber has at least one end coupled to a photomultiplier. Data output from each photomultiplier is collected and processed to determine spatial coordinates of the origination position of a detected gamma ray. The present invention provides a high resolution gamma ray detector having an improved signal-to-noise ratio. This improves significantly the diagnostic power of the presently used PET and SPECT systems, and greatly extends the field of their application both in medical diagnosis and research. In addition, the present invention enables use of longer-lived positron emitting radioactive isotopes than presently used in typical PET systems.

Abstract: A method for clamping the black level of a television signal comprises converting the input video signal to a digital input signal and, by means of a measuring circuit, measuring the signal level during a blanking period of the input video signal. The measured signal level is compared with a digital reference level to generate a digital error signal. A correction signal derived from the error signal at correction generator is added to the samples forming the digital input signal with any residue of the truncated addition at each sample being retained for addition with the correction signal to the next sample. <IMAGE>

Title: Resistor production using thick film techniques - employs resistance materials with only two different conductivity values
IPC: H01C17/065
Filed: 1968-11-02
Abstract: The technique is applicable to the manufacture of a wide range of resistance values by applying the conducting pastes to insulating substrates, for example circuit cards. Differing resistance values over a wide range are achieved by determining the shape of the resistor and by two printing stages. The first application is allowed to dry. The second application, using a paste of differing conductivity, is then printed on, overlapping the first as necessary, to give the required resistance value. After drying the second layer the whole is then cured or sintered to complete the process. Terminal plates may also be in the form of a grid.

Title: Drill pipe side pocket spur - for higher internal pressure by relocated welding seams between and spur housing
IPC: E03B3/16
Filed: 1971-09-03
Abstract: A side pocket spur for drill pipes consists of a valve pocket housing which is butt welded into a cut-out of the spur housing. Axial bore of the latter is in line with the bore of the drill pipes and has a circular cross-section where the valve pocket housing is welded to it. Axial welded seams which fix the valve pocket housing to teh spur housing lie on the side of the longitudinal axis and are offset by a distance which does not exceed the radius of the bore. This enables automatic welding rigs to be used for the welds and reduces the forces exerted on the welded seams. The new spur can withstand higher internal pressures and can be produced at lower cost.

Inventor: UOREN HENRII NIKORUSON
IPC: H04N9/64
Filed: 1986-02-03
Abstract: The signal processor includes a field or frame store (24). If a video signal having a non-standard relationship between its line frequency (fH) and its color subcarrier frequency (fSC) is processed, corresponding signal samples from an analog-to-digital converter (12) of successive fields or frames are misaligned in the store, leading to a degradation of the processed signal. A nonstandard signal detector (22, 19, 23, 21) produces a control signal indicative of the existance of the non-standard relationship and the mode of operation of the processor is controlled accordingly. In one example, field or frame processing and line processing are selectively performed depending on the control signal, line processing being performed in the presence of the non-standard signal.

Patent JP-S5944530-B2 (JP)
IPC: F16D65/56
Filed: 1976-04-02
Abstract: A heavy duty disc brake is disclosed which is provided with an automatic adjuster mechanism to limit retraction of the friction elements to a substantially predetermined amount to thereby maintain the running clearances between the friction elements and the brake rotor substantially constant. The adjustment mechanism includes an extensible member which is slidably mounted within the caliper housing and which interconnects a mechanical actuating mechanism and a piston which engages one of the friction pads. The piston is slidably mounted within the housing and is disposed between the extensible element and the corresponding friction pad, and the piston carries a spring-actuated pawl. The pawl is adapted to engage corresponding ratchet teeth on one portion of the extendible member, which includes a pair of threadedly interconnected, relatively rotatable members, designed so that upon relative rotation between the members, the extendible member extends. When a brake application is effected, the mechanical actuator thrusts the extendible member, and therefore the piston and the friction elements, toward the rotor. Upon brake release, a spring yieldably urges the extendible member toward a predetermined brake release position. If the extendible member must travel more than a predetermined distance relative to the piston to achieve the brake released position, the pawl indexes to another one of the aforementioned teeth carried on the extendible member. Therefore, on a subsequent brake application, the pawl rotates one portion of the extendible member relative to the other portion, consequently extending the member.

Abstract: A bearing clamping assembly for a gas turbine engine for preventing relative rotation between a first shaft and a shaft bearing assembly race in the event of bearing failure. The clamping assembly is comprised of an axially resilient member disposed near the bearing assembly which applies an axial force to the bearing race to maintain it in position relative to the shaft. The first shaft is secured to a second shaft by an axial clamp. The clamping of the two shafts compresses the resilient member which responds by applying the axial force on the bearing race to maintain the race in position in the event of bearing failure.
