Title: Take-off device for tapping pipelines
IPC: F16L41/06
Filed: 1980-06-27
Abstract: This invention relates to a fluid take off device for tapping fluid from pipelines and comprising a two-part sleeve 12 fitted around the tube from which fluid is to be tapped and a valve 7 to be screwed on the sleeve and fitted with a hollow piercing bit. The packing 9 between valve and sleeve is placed in an annular recess interrupting the thread 5 in the valve section bearing the piercing bit, whereas the sleeve-half 1 is designed so that the corresponding thread 4 on which the valve is threaded is interrupted at the outer end so as to leave a length having a cylindrical surface so that the packing will act as a seal between the two cylindrical surfaces even when adjusting the valve by rotation to its most favourable position, without loss of the seal. In order to ensure a stable positioning of the valve, a nut 11 is screwed on to the thread of the valve and this nut is tightened against the sleeve half 1 after adjustment of the valve position. <IMAGE>

Title: Detecting change in fluid flow conditions
IPC: G01F1/688
Filed: 1981-09-04
Abstract: Transient changes in heat flux due to small variations in flow conditions, such as from no-flow to flow or vice versa, particularly within a series of relief flowlines 13 forming a component part of a flaring system 2 associated with a chemical or refinery complex 12, are detected in order to pinpoint a source of plant upset, so that corrective action can be taken. The changes in heat flux are monitored within each major relief flowline 13 using heat flux transducers 19 arranged on and in contact with the exterior of the flowline, in series with signal indicating means, such as a recorder and/or an audio- alarm system. Cascading the signal output, i.e. serially combining the outputs of N thermocouples of the transducer so as to form a thermopile enhances sensitivity. Preferably N is about 80, but can be as high as 320. The thermocouples are attached to upper and lower metallic plates of the heat flux transducer with the upper plate being in heat transfer contact with a sector of the flowline. <IMAGE>

Title: A broadband saturable reactor regulated power supply
Inventor: GRACE ALAN G V
IPC: G05F1/38
Filed: 1981-11-25
Abstract: A saturable reactor regulated power supply utilizes a power oscillator to convert line voltage to a higher frequency voltage which is passed through the gate windings of a saturable reactor to an output AC or DC circuit. A feedback circuit inter- connected between the output circuit and control windings of the saturable reactor controls the control winding current to pulse modulate the voltage applied to the output circuit. The feedback circuit synthesizes a series control winding resistance which enables broad bandwidth operation of the power supply and less power dissipation therein. The feedback circuit includes a voltage or current sensor 96 supplying a signal by way of a comparator amplifier circuit 98 to a driver circuit 100 connected to the reactor control windings over lines 78, 80. Resistors R1, R2, R3 and an amplifier controlling transistors 118, 124 synthesise an effective resistance in series with the control windings to reduce the time constant of the circuit without increasing power dissipation. Multiple output channels may be provided. <IMAGE>

Patent GB-2116027-A (GB)
Title: Toothbrush
Inventor: HUNT ANTHONY ERIC JOHN
IPC: A61C17/26
Filed: 1982-02-02
Abstract: An apparatus for cleaning teeth or dentures in which a brush 1 with radial bristle is made to rotate about its longitudinal axis to produce a brushing action continuously in one direction. A means 27 for selectably reversing the direction of rotation of the brush is incorporated so that the brushing action changes from a first direction to a direction opposite to the first direction. The brush is applied to the teeth or dentures and a direction of rotation is selected such that the brushing action is in a direction away from the gum or denture plate. The action of brushing the teeth continuously in one direction away from the gum effectively removes plaque from the surface of the teeth whilst avoiding any brushing action which could push plaque upwards into the gum or sideways into tooth crevices. <IMAGE>

Title: Forming a pattern of a thin film having metallic lustre
Inventor: KAMATA YUTAKA
IPC: G03F7/09
Filed: 1982-09-14
Abstract: To prevent incorrect exposure of a photoresist layer 4 formed over a film 3 having metallic lustre due to reflections from steps 31 in the film reaching the photoresist a layer 7 of silicon nitride which does not transmit these reflections is provided between the film and the photoresist layer. Where a phototresist layer sensitive to ultraviolet or for ultra-violet radiation is formed over an aluminium film to provide a wiring layer for a semiconductor integrated circuit this silicon nitride layer is formed by radio frequency glow discharge using a gas containing ammonia and silane. After exposure of the photoresist, the silicon nitride layer is etched away using the photoresist layer as a mask, and the aluminium is etched using the silicon nitride as a mask. <IMAGE>

Abstract: Described herein are "polydomas", the product of the fusion of a hybridoma with a B-lymphocyte or another hybridoma. The polydomas produce a hybrid monoclonal antibody having a dual specificity against two different antigenic determinants. Also described are immunodiagnostic and immunotherapeutic processes which utilize the hybrid monoclonal antibodies or other antibodies having a dual specificity. In those processes, one specificity of the antibody is directed against a target antigen and the other against a moiety which permits a diagnosis to be made or which delivers an agent lethal to the target antigen or associated tissue.

Patent GB-2158591-A (GB)
Title: Durability testing
Inventor: LONG ADRIAN ERNEST
IPC: G01M3/26
Filed: 1984-05-11
Abstract: The rim of a cup-shaped body 7, 6 is bonded to the surface of a specimen (22 fig 4) to be non-destructively tested, (eg in-situ concrete or other porous material), and the interior of the cup and a communicating hydraulic cylinder 4 are filled with fluid through an inlet 10. A micrometer 1 is then turned to cause a piston 3 to descend within the cylinder, closing the inlet and so creating an enclosed volume of of pressurised fluid. The pressure of that volume (indicated by a gauge 8) now tends to fall gradually because fluid escapes from the enclosed volume by permeating through the specimen 22. At intervals the micrometer is turned to progress the piston, to make up the volume and restore the pressure to its original value. Durability is calculated from the amount of turn required on each occasion, and the time intervals between successive occasions. An automated version of such apparatus is also disclosed, as is the facility to acquire further useful information at the end of each test by increasing the fluid pressure to a value at which the cup parts from the specimen, by reason of failure either of the bond between the specimen and the rim 6, or of the structure of the specimen itself in the vicinity of the bond. <IMAGE>
