Patent CA-1069977-A (CA)
Title: Device for measuring the alternating current flowing in a high tension line
Inventor: BOIRAT ROBERT
IPC: G01R15/22
Filed: 1977-01-12
Granted: 1980-01-15
Abstract: ABSTRACT OF THE DISCLOSURE     Shunt means supply a diode bridge with an alternating cur-rent proportional to the AC to be measured. The bridge has at least two electroluminescent diodes which emit two al-ternating streams of half-wave light pulses which are supplied to two fibre optic systems. These convey the light signals to a safe distance from the high tension line where two light receptors receive the respective streams of half-wave light pulses and apply electrical signals proportional thereto to opposite inputs of a differential amplifier. The output of the amplifier is a readily measurable AC. Balanc-ing means may be provided to compensate for any differences in the overall transmission paths for the two half-wave pulse streams. A resistive  load may be provided adjacent the line to sink the current flowing through the diode bridge.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of attaching a slide fastener to a garment having a slotted closure opening of a given length is dis-closed.  Rows of fastener elements, carried on and along confronting longitudinal edges of a pair of stringer tapes are interengaged to couple the same. The stringer tapes are longer than the closure opening.  A slider is mounted onto the interengaged rows of fastener elements at their lower ends.  The garment is turned inside out.  The coupled stringer tapes are placed onto the garment in such a manner that the outer surfaces of the coupled stringer tapes are mated with opposed inner marginal portions of the closure opening, with the interengaged rows of fastener elements in alignment with the closure opening, and with the slider dis-posed downwardly of the lower end of the closure opening.          The coupled stringer tapes are sewn respectively to the opposed inner marginal portions by lines of stitching except at the lower portions thereof extending downwardly of the lower end of the closure opening.  The slider is moved upwardly beyond the lower end of the closure opening.

Abstract: TITLE:  IMPROVEMENTS IN FLUORESCENT LAMPS            ABSTRACT OF THE DISCLOSURE:     The invention relates to electrode mount assemblies for electric discharge and fluorescent lamps.   In accordance with the first aspect of the invention the portions of the electrode support wires which are exposed to electron bombardment within the body of the lamp have at least their surface formed of refractory material.   The exposed portions may be coated with a refractory material such as boron nitride or made wholly of a refractory metal such as molybdenum.   According to a second aspect of the invention relatively cheap soda-lime silicate glass can be used for the end flares of the lamp tubes, because the provision of refractory surfaces on the vulnerable portions of the support wires enables a metal to be chosen for the portions of the wires passing through the glass seal which closely matches the glass in thermal expansion coefficient.  The invention improves the life of lamps by reducing end blackening, reduces the incidence of cracks in the punch seal or neck regions of the lamp and may enable cheaper materials to be used for various structural items.

Abstract: ABSTRACT             An electrosurgical unit having a feedback control circuit for providing control of the power amplifier of the unit so power delivered to tissue presented between the active and return electrodes of the unit will be substan-tially constant over the range of impedance presented by various tissues that are encountered.  The feedback signal to the power amplifier is determined from a comparison of a power level reference signal and the mathematical product of two signals which are derived from a sensed current in the unit that is directly related to current delivered to tissue and a sensed voltage that is directly related to voltage delivered to tissue.  A non-linear compensation circuit in the feedback circuit corrects for non-linearities introduced by components selected for the circuit.

Abstract: ABSTRACT OF THE DISCLOSURE           A progressing cavity fluid motor for driving a drill bit for deep drilling tools is described.  Such a motor is mounted on a drill string and is powered by a fluid such as drilling mud.  The pump includes a housing, a stator with female helical threads within the housing and a rotor with male helical threads mounted inside of the stator.  The drill bit is connect-ed to the rotor.  In the present invention the rotor has a threaded surface which is formed of an elastically deformable sleeve supported by a carrier shaft.  The sleeve is mounted on the carrier shaft in such a manner as to prevent rotation between the two so that the sleeve drives the shaft by positive engage-ment between these two elements.  Means are arranged for intro-ducing a pressure inside of the elastically deformable sleeve for expanding the sleeve radially outwardly.  This pressure is greater than the fluid pressure existing in the working cavity between the facing surfaces of the male and female threads and preferably changes as a function of the working pressure in the drilling mud.

Abstract: ABSTRACT OF THE DISCLOSURE         A mounting base for supporting a standard footed motor in driving relationship on a C-faced reducer of a gear motor to enable it to be driven by the footed motor without requiring the use of a different interface adaptor.  The motor mounting base is characterized by having two orthogonally disposed walls one of which has a planar surface adapted for engagement with the C-faced reducer, while the other wall has a planar surface for supporting a footed motor.  The planar surfaces are machined to be essentially perpendicular and are further characterized by having sets of apertures through their associated walls for receiving mounting bolts to secure, respectively, the mounting base in operating position on the C-faced reducer and the base to a footed motor.          The sets of apertures are shaped to afford clearance fits with the securing bolts to enable the footed motor to be accurately aligned with driven shaft of the gear motor, and to support the footed motor in such an accurately aligned position relative to the gear motor so that a flexible shaft coupling need not be used between the two shafts.

Abstract: ABSTRACT        This invention is concerned with a novel process for production of 4-substituted 1,2-diphenyl-3,5-dioxopyrazolidines of general formula   I where R and R1, which by be identical to or different from each other, represent a hydrogen atom, a lower alkyl group, a phenyl group or the group -COOR" (where R" means hydrogen or a lower alkyl group) and A a hydrogen atom or a hydroxyl group.  Compounds of general formula I exist in the so-called Z- and in the isomeric E-form, which fall both under the general formula designated above (as well as mixtures thereof).  The compounds of formula I are prepared by either (a) reacting a cyclosemiacetal of general formula                 II   where A' represents hydrogen or an etherified hydroxyl group, preferably the .beta.-methoxyethoxymethoxy (=MEM) group, with a triarylphosphorane derivative of general formula                 III     where R and R' have the above-mentioned meanings and Ar represents a phenyl group (optionally substituted with an inert group such as methyl, methoxy or phenyl) and, subsequently, optionally liberating the etherified hydroxy group by means of a mild Lewis-acid; or reacting the aldehyde of the formula                 IIa with a compound of formula III as defined above.  The compounds of formula I are valuable antiphologistically active compounds.  The inter-mediates of formulae II and IIa are novel and form part of this invention. They are prepared by rearrangement or deketalisation of the corresponding cyclic acetals of general formula                 IV where A' has the meanings indicated above.  This rearrangement may be effected, for example, by means of simple heating in aqueous ethanol.
