Title: Bore hole scanner with position detecting device and light polarizers
Inventor: IIZUKA YUNOSUKE
IPC: E21B47/00
Filed: 1988-10-27
Granted: 1993-06-29
Abstract: ABSTRACT OF THE DISCLOSURE       A bore hold scanner includes a light projecting device for projecting a light beam toward a bore hole wall surface. conical mirror is arranged coaxially with respect to a sonde for condensing light reflected from the bore hole wall surface.  An image forming device is arranged in front of the conical mirror.          A photoelectric transducing device converts a light signal into an electric signal.  Optical fibers introduce an image, which is formed on concentric circles by the image forming device, to the photoelectric transducing device.  A data processing device scans and extracts signals from the photoelectric transducing device, and generates and processes image data indicative of the bore hole wall surface.   A sonde position detecting device detects the orientation and position of the sonde.   Rotating portions are dispensed with by using the conical mirror and optical fibers, and a linear CCD array can be used as the photoelectric transducing device.

Abstract: The invention provides patch-rubbers for repairing radial-ply and bias-ply tires.  The patch-rubbers, while showing the same strength as known ones, are more flexible and do not affect the original mechanical features and performance of the repaired regions of tires.  The patch-rubbers are also suitable for retreading operations on tires by use of both high pressure molding machines and autoclaves.  The rubber-patches essentially consists of superposed plies embedding fiber cords in such a way that their medium axis diverge from the symmetry axis of the patch-rubbers; and superposed on the plies, a further ply of smaller area having rectilinear metallic cords forming a different angle with the symmetry axis.

Abstract: ABSTRACT            Extraction of lactones from a lipid material, by contacting a medium, having a temperature near its critical temperature and a pressure near its critical pressure with the lipid material, and subsequently removing the medium, wherein the medium, upon contacting, has a temperature T (in °C), and pressure P (in bar), such that:  -25 <= T* <= 18.5; -40 <= P* <= 300; and T*xP* <= 1900, where T* = T-Tc, P* = P-Pc, Tc is the critical temperature (in °c), and Pc is the critical pressure (in bar) of said medium.  Under these conditions a low yield and a high selectivity are obtained, resulting in a relatively small extracted fraction, which is substantially enriched in lactones.  Another aspect is the use of an extract obtained by the above process for flavouring foodstuffs.

Abstract: SELECTIVE SOLDER FORMATION ON     PRINTER CIRCUIT BOARDS            Abstract Disclosed is a method of providing solder on selected portions of a printed circuit board. Solder is first electroplated over copper conductor patterns on the board by means of a first photoresist layer. After stripping the first photoresist, a second photoresist layer is laminated over the board and developed to expose selected portions of the solder. The exposed portions are selectively stripped. The copper exposed by the selective stripping is then subjected to a scrubbing while the photoresist protects the remaining solder, and the second photoresist is removed.

Abstract: A plant for performing the method is characterized by containing a pump (11) which has a relatively small inlet opening (10) so that the pump (11) creates a negative pressure in the portion (12) of the heat exchanger (9) where the liquid, fed by means of a nozzle (13), evaporates. This allows large amounts of water to evaporate, and the flue gas, which flows through the heat exchanger portion (14), is cooled to a low temperature. The flue gas will then condense, and this procedure is accelerated by the constriction (at 16) of the flue (15) so that there is a positive pressure in the heat exchanger portion (14). According to the heat pump principle, the advantages are an unprecented low temperature level and humidity content of the discharged flue gas and a correspondingly high efficiency of the firing plant.

Abstract: An article surveillance system employs a label or tag containing a non-linear impedance element, such as a semi-conductor diode, connected to a metal antenna loop configured to pick up two distinct radio frequency transmissions displaced on either side of a selected center frequency. The non-linear impedance element connects opposing sides of a closed loop section at one end of the antenna to form a tuned tank circuit having a resonant frequency twice that of the selected center frequency. A first transmitter generates a tone modulated radio frequency displaced on one side of the center frequency, and a second transmitter generates a continuous wave radio frequency displaced from the center frequency on the other side. Both transmitter signals are fed separately to respective radiating antennae located adjacent to a surveillance area. The antennae are chosen to produce circularly polarized transmission of both frequencies within the surveillance area. The two different frequencies picked up by the transponder antenna are mixed by the non-linear impedance causing the tank circuit to resonate at a single higher frequency equal to their sum, which is double the center frequency; that resonant frequency is reradiated to be picked up by a receiver antenna or antennae suitably placed with respect to the surveillance zone to be detected by a very narrow band receiver responsive to the sum frequency. The modulating tone signal is derived from the received signal to produce a gradually increasing charge that is compared against a preselected threshold level to trigger an alarm for a fixed interval only when the detected signal is of a sufficient strength and duration.

Abstract: Method and apparatus for marking a film with patient data and possible other information in panoramic tomography X-ray photography. In the method the X-ray beam (X) creating the X-ray photograph and the X-ray film (F) move in a certain way in relation to each other. A certain area (F<sub>y</sub>) of the film (F) is reserved for markings made with the method, which markings are made latent on the film to become visible when the X-ray film is (F) developed. Markings are made simultaneously with the film (F) exposure to an X-ray beam (X) for X-ray photography. The markings are made as a sequence by using, as the deflection parallel with the marking row, the relative movement of the radiation (X; L) with which the marking is made on the film and the film (F) itself, which movement is synchronized with the relative movement of the X-ray beam (X), to which the film is exposed for actual X-ray photography, and the film (F) itself.

When the transporter is displaced a distance corresponding to the interspace between the groups, the whole group of cores is introduced into the curing means (5), in which the group of cores is detached from the transporter for the time of the curing, being thereafter returned to the following empty space on the transporter.

Abstract: A method for producing a self-supporting ceramic composite structure comprising a ceramic matrix embedding a filler (38) includes oxidizing a parent metal to form a polycrystalline material comprising the oxidation reaction product of the parent metal with an oxidant and, optionally, one or more metallic constituents, and the filler (38) embedded by the matrix.

The first source (36) of molten parent metal is reacted with the oxidant to form the oxidation reaction product and is replenished from the reservoir (34) as the reacting continues for a time sufficient to grow the oxidation reaction product to a desired boundary and thereby embed at least a portion of the bedding of filler (38) within the oxidation reaction product to form the ceramic composite structure. The bedding of filler (38) may have any suitable shape, including that of a hollow body, the interior of which is contacted by the first source (36) of molten parent metal to grow the oxidation reaction product through the shaped, hollow body of filler.
