Patent CA-2037191-A1 (CA)
Title: Revolving applicator device
Inventor: BROBERG ERIC
IPC: B08B9/02
Filed: 1991-02-27
Abstract: REVOLVING APPLICATOR DEVICE               Abstract of the Disclosure A  revolving  applicator  device  for  sandblasting  the interior of sewer pipes and the like comprises a hose running freely through the centre of a hollow pipe in the form of a rotating arm.  Each end of the hose is held securely within the hollow pipe by means of bearings or other similar mech-anism.  One end is attached to a source of material (sand or shotcrete) while a nozzle is attached to the other end.  One end of the hollow pipe or rotating arm is mounted to cylin-der which rotates about a fixed axle thereby allowing the arm to freely rotate around the axle also.  The hollow pipe or rotating arm is formed in an arc so that as it rotates the nozzle end covers a wider circle than the end attached to the axle.   A gear attached to a pneumatic motor by means of a chain drives a cylinder which in turn is attached to and turns the rotating arm.  As the arm rotates, the hose does not twist but simply bends.  In this way, the nozzle can be automati-cally rotated through 360 degree motion without causing any torsion in the hose.

Abstract: ELECTROSURGICAL INSTRUMENT HAVING NEEDLE CUTTING         ELECTRODE AND SPOT-COAG ELECTRODE                   ABSTRACT OF THE DISCLOSURE    An electrosurgical instrument for use in combination with an endoscope  for  cutting tissue  and  cauterizing/coagulating  the resulting wound area is described.  The instrument comprises an elongated flexible tubular member having a proximal end, a distal end, and plural lumens extending therebetween.   Affixed to the distal end of the tube is a bullet-shaped ceramic tip member having a centrally-disposed longitudinal bore passing through the side wall of the tip member.  The ceramic exterior surface of the tip member is covered with a conductive layer forming a first inactive electrode.   An electrical conductor joined to that electrode surface feeds back through a lumen of the tube to its proximal end where it may be coupled to an electrosurgical generator.   Also running through a lumen in the tube is another conductor which can be made to project outwardly through the opening in the tip member.          A hub having a spring-loaded plunger is affixed to the proximal end of the tube with the plunger joined to the wire so that when the plunger is depressed, the distal end of the wire will project a short distance beyond the extremity of the tip member.  By coupling this second conductor to an electrosurgical generator, it becomes the active electrode of a bipolar pair.

Title: Gasoline engine fuels of enhanced properties
Inventor: LEEPER THOMAS A
IPC: C10L1/02
Filed: 1991-06-26
Abstract: Methods and compositions for reducing the maximum reactivity of exhaust products emitted by spark-ignition internal combustion engines. Gasoline having a minimum target octane number is formed by blending together base fuel blending components and at least one cyclopentadienyl manganese tricarbonyl compound in an amount equivalent to up to 1/32 gram of manganese per gallon. The manganese compound is used in lieu of an amount of one or more aromatic gasoline hydro-carbons required to achieve the same target octane number so that the maximum reactivity of the tailpipe exhaust products produced by the manganese-containing gasoline is less than the maximum reactivity of the tailpipe exhaust products produced by the same base fuel blending components not containing any such man-ganese compound but containing in lieu thereof an amount of one or more aromatic gasoline hydrocarbons required to achieve the same target octane number. There is thus provided a way of providing and using gasolines of suitable octane values while concomitantly reducing the potential for ground ozone formation, smog formation, and other grievous consequences of atmospheric pollution.

Title: Closure with high energy button
Inventor: HEILMAN ROBERT J
IPC: B65D41/16
Filed: 1991-07-04
Abstract: This related to a conventional type of closure having a control button which is normally provided with an "up" convex state and which is movable by a vacuum within an associated container to a "down" concave state. The button, as formed, has a zero or tensile stress state with the stress state changing to a compressive stress state when the button is drawn downwardly by a vacuum within the associated container.      In accordance with this invention, the button has been reformed so that it is slightly flattened and this reforming has changed the zero or tensile stress state to a compressive stress state thereby providing the button  with more stored energy when it is drawn downwardly by a vacuum within an associated container.      This additional stored energy provides for a greater flipping action of the button which can be utilized to operate an irreversible tamper indicating system which may be applied to than button.

Title: Method and device for measuring the integrity of a transmission
Inventor: BECAVIN HENRI
IPC: G01R29/08
Filed: 1991-09-19
Abstract: Device and method for permanently checking the integrity of a transmission affected by parameters not directly accessible to measurement and whose influence on the modulus and phase of the field radiated in space can be determined by utilizing a mathematic model, the transmission being from an antenna array. Each antenna is supplied with one or more Hf carrier frequencies, each being modulated in a known way by one or more sinusoidal low frequency signals. First, a recording is made, at least at one point and during a time period T, of the amplitude of the combination of the signal received at this point and of a reference signal, having a fundamental frequency equal to one of the HF frequencies of the signal to be analyzed. Then, the amplitude of low frequency components of the signal thus obtained is extracted and memorized. Then, steps 1 and 2 are repeated n times (n is a whole number) in recording the signal at the same point and in carrying out, at each time, a phase shift of the reference signal by a quantity  <IMAGE>  k is a whole number successively assuming all values between 1 and n. The n amplitudes thus memorized are processed as the n values of function F( alpha k), from which values certain coefficients of its Fourier transform are extracted. The operations 1 to 4 are then repeated at least as many times as there are points of measurement. Values of the unknown parameters are then determined using the mathematical model.

Abstract: A composite, prestressed structural member,  such as a bridge unit and methods of forming such a member.   The apparatus includes a plurality of longitudinally extending girders which are transversely spaced and a plurality of adjacent composite units disposed on the girders.  Each com-posite unit has a plurality of beams with a molded deck por-tion  formed  thereabove.     The  beams   are  positioned transversely  with  respect  to  the  girders  and  attached thereto.   Additional, longitudinal beams are disposed bet-ween the transversely extending beams over the girders.  The longitudinal beams are attached to the girders and by con-nectors to the molded deck.   The structure is formed by positioning the girders on a construction support adjacent to a center portion of the girders such that the free ends of the girders cantilever and deflect downwardly.  The beams of the composite units are attached to the girders in this construction position.  Any gaps between adjacent composite units are filled with a non-shrink,  high strength grout.          When moved to an operating position wherein opposite ends of the girders are supported,  the natural deflection of the unit  due  to  its  weight  imparts  a  compressive  prestress longitudinally in the molded deck units.  Each molded deck unit  may  be  formed  such  that it  is  also  transversely prestressed.
