Title: Subsea pipeline test cap and pipeline installation method
IPC: G01M3/02
Filed: 1981-09-02
Abstract: A high-pressure test cap is provided for mounting on a multiconduit pipeline for use in testing the structural integrity and pressurized-fluid handling capability of the pipeline after it has been positioned on the marine floor but before it is connected. The test cap can be removed from the pipeline and recovered from the marine floor for reuse. The test cap comprises a body portion (36) having an open sided yoke (34) Figure 4, not shown to receive a mounting collar of the pipeline; a plurality of cylindrical chambers (40) in the body portion each aligned with a conduit in the mounting collar and each having a piston (50) mounted for axial movement within the chamber; and passage (56) which enable each cylindrical chamber to be pressurized in communication with the aligned conduit and force the piston against the mounting collar, to test the integrity of the pipeline conduit. A centre-post 280 (Figure 8, not shown) may be provided in the fluid passage 56, which will take an impression when a suitable through-flowline tool hits it, in order to check the ability of the conduit to allow such tools to pass through. <IMAGE>

Title: Power-on reset circuit
Inventor: BRENT MICHAEL ANTHONY
IPC: H03K3/3565
Filed: 1981-10-20
Abstract: A voltage responsive circuit provides a logic high output signal when a supply voltage is below a predetermined value and a logic low signal when the supply voltage is above the predetermined value. The circuit includes an input switching stage (T1 to T6) and an output buffer stage (T7 to T10), the input switching stage being such that, on power-up, a logic high output signal is produced until the supply voltage rises above the predetermined level. A reference voltage for the circuit is provided, e.g. by a Zener diode (ZD1). The circuit samples the supply voltage periodically in response to a clock pulse signal. This provides a very low power dissipation. <IMAGE>

Title: Volumetric measuring device
Inventor: DAWE GARFIELD ASBURY
IPC: A61M5/168
Filed: 1982-06-21
Abstract: In a device for measuring the volume of flow in a liquid conveying apparatus drops of the liquid are formed (46) and directed (19) into a length of measurement tubing (48) of known internal diameter to form a liquid column (61) the length of which is determined by two spaced apart liquid sensors (30,32). The measured drops then pass to a collector means 53. Electronic circuitry calculates the time elapsed for the leading edge (63) of the column (61) to interrupt sensors (30, 32). The time for the trailing edge (64) to pass sensor (30) is proportioned to the length of the column (61) and the quotient of the two values will give the actual length. Accordingly, accurate volume determinations can be made irrespective of velocity change such as due to viscosity, surface tension or back pressure. The device is especially adapted to be used in conjunction with an intravenous administration set. <IMAGE>

Title: A tissue adhesive and a method of producing the same
Inventor: REDL HEINZ
IPC: A61K35/14
Filed: 1982-07-06
Abstract: A tissue adhesive based on human or animal proteins contains factor XIII, fibrinogen and an antibiotic. In order to achieve a high straining capacity of the adherences and a retarded antimicrobial efficacy, the ratio of factor XIII to fibrinogen, expressed in units of factor XIII per gram of fibrinogen, amounts to at least 500. The antibiotic is chosen among amino-glucosides, beta- lactams, polypeptides or tetracyclines. In a method of producing the tissue adhesive the concentration ratio of factor XIII to fibrinogen is adjusted in a fibrinogen-containing blood plasma fraction by the addition of factor XIII. The antibiotic is added either before deepfreezing or lyophilization of the resulting preparation, or after thawing or reconstitution of the same.

Title: Optically aiming detectors
Inventor: GLAZAR ARTHUR J
IPC: G01V8/14
Filed: 1983-04-26
Abstract: An optical sensor (10), such as an infrared sensor for detecting overheated wheels or wheel bearing on trains passing along a section of track, comprises an optical system (24) having its receiving optical axis angled (e.g. perpendicularly) to the line of sight of the sensor through a sighting aperture (26). A mirror (30) is pivotally mounted in the line of sight and is movable between a first (operating) position in which it reflects rays travelling along the line of sight to the optical system (24), and a second (aiming) position in which an observer can look through a viewing aperture in the top of the sensor and see through the sighting aperture (26) via the mirror (30). When cross hairs (36) between the viewing aperture and the mirror (30) appear superimposed on cross hairs (38) between the mirror (30) and the sighting aperture (26), the observers' line of sight through the aperture (26) is the same as that of the optical system (24) when the mirror is in the first position, thus permitting the sensor to be aimed accurately and easily at a target. <IMAGE>
