Abstract: CUTTING TOOL             ABSTRACT OF THE DISCLOSURE        A shear is disclosed in a preferred form which is particularly suited for cutting and trimming hair and which includes means for varying the length of stroke of the cutting blade or blades which reciprocate generally parallel to the longitudinal axis of the handle, so that the unit can be manipulated in a manner similar to a comb or brush.  The blade drive includes a transmission com-prising a pair of eccentrics which are selectively phaseable to provide full range of stroke by addition and subtraction of their eccentric throws.  The eccentrics are retained in their selected phase relationship by spring and frictional means which provide an overload release permitting the eccentrics to rephase to zero stroke when the imposed load overcomes the phase-retaining means.  Control of the unit is effected by a rotatable and depressable button which controls the drive motor, adjusts the blade stroke by phasing of the eccentrics, and levers the cutting blade or blades from a retracted position into a cutting position.     This is a divisional of Canadian Patent Application Serial No. 299,494 filed March 22, 1978.

Abstract: TITLE     LASER TRIGGERED HIGH VOLTAGE                    RAIL GAP SWITCH     INVENTORS     Roderick S. Taylor Kurt E. Leopold A. John Alcock ABSTRACT OF THE DISCLOSURE              The laser-triggered high voltage rail gap switch includes two parallel electrodes in a high pressure environment of SF6 and Ar.  A pulsed UV laser directs a coherent beam parallel to the electrodes to initiate multichannel breakdown in the gap between the electrodes.          This breakdown occurs at a fixed time delay after the laser pulse.  This breakdown is enhanced by including an organic additive such as fluorobenzene or tri-n-propylamine in the gas mixture.

Abstract: ABSTRACT OF THE DISCLOSURE          In a dump truck, the most efficient way of raising the container body is to apply a lifting force to the end of the body remote from the pivot point.  In some applications it is difficult to do so because of height restrictions and it is particularly difficult to do so in a telescoping container body in which the end of the container body which is remote from the pivot point moves in relation to the pivot point. The present invention overcomes this difficulty by mounting the extensible ram in a position remote from its upright position and providing a mechanism for pivoting it to its required upright position prior to its operation as a hoist.      In a telescopic container body, the extensible ram is normally stored in freeboard space disposed below the front section of the container body and is raised into an upright position at the front end of the telescoped body in response to movement of the front section from its extended position to its retracted position.  The power supplied to the jacking ram and to the telescoping ram is controlled so that the telescoping ram cannot be activated when the jacking ram is activated and vice versa.

Title: Filling effect designs on a stitch-through fabric
Inventor: ROSNER STANLEY S
IPC: D04B23/10
Filed: 1980-09-09
Granted: 1983-07-19
Abstract: ABSTRACT Filling Effect Designs On A Stitch-Through Fabric A novel concept in stitch-bonded fabrics made on a stitch-through type machine such as a Malimo machine is disclosed which involves in one embodiment, the creation of a block pattern design using a textile pattern design element (e.g., a single yarn end) disposed along non-rectilinear pathways, with segments of the design element extending essentially perpendicular to the longitudinal direction of the fabric. A single system of longitudinal knitting thread wales, each wale comprising a multiplicity of looped stitch courses which engage the design element with loops of knitting thread on the rear surface of the fabric and laps of the knitting thread courses on the front surface, binds and secures the design element into an integrated unitary textile structure. In one embodi-ment, a block pattern design is formed from a single tex-tile element having segments of substantial length dis-posed in parallel configuration perpendicular to the longitudinal direction of the fabric. The creation of the present fabric is made possible by the method and apparatus of the invention, which, in one embodiment, comprises a novel yarn feeding mechanism for guiding a textile pattern design element through a tube, the exit end of which delivers the element at a point in proximity to the fabric-forming work zone of the stitch-through machine, whereupon a circular rotating brush flanking the tube engages the element and places or pushes it into the work zone and holds it down therein whereupon the segment of the design element thus placed is stitched into the fabric construction while disposed essentially parallel to the elongated work zone during a stitching cycle of the stitch-through machine. In this way the stitched-in segment becomes a horizontal decorative yarn portion integral with the fabric. The tube and circular brush cooperate as a unitary design element feed mechanism adapted to reciprocate along the work zone by a pre-programmed computer-controlled stepping motor which propels the design element feed mechanism by means, e.g,, of a flexible drive belt. The aggregate effect of this operation is a pre-determined design pattern on the fabric derived from a single textile element.

Abstract: PROCESS FOR THE PURIFICATION OF WET-PROCESSED            PHOSPHORIC ACID      ABSTRACT OF THE DISCLOSURE:      The invention relates to a process for the purification of wet-processed phosphoric acid with the aid of organic solvents which are immiscible or only partially miscible with water, the sulfate ions being removed by addition of barium compounds. The purification is carried out in an n-stage extraction installation, where n is equal to or greater than 5. The barium compound is added to the phosphoric acid to be purified, and the resulting mixture is fed to the top of the extraction installation, in which the organic solvent phase is dispersed in the aqueous phase. The sulfuric acid is led in counter-current fashion to the phosphoric acid by adding it to one of the stages n = 4 to at most n-1.

Abstract: ABSTRACT OF THE DISCLOSURE            A process is disclosed for the manufacture of microcapsules which comprises the steps of preparing hydrophobic and hydrophilic phase components.  The hydrophobic phase compo-nent comprises a homogeneous solution of an electron donat-ing chromogenic material and a hydrophobic material.  The hydrophilic phase component comprises a mixture of a regu-lating agent and water, the regulating agent being a starch material. The  hydrophobic phase component is combined with a hydrophilic phase component to form an oil-in-water emulsion.  The oil-in-water emulsion further contains aqueous solutions of urea, resorcinol and formaldehyde. The pH of the oil-in-water emulsion is adjusted to a level at which the capsule wall forming reaction is initiated by the addition of a catalyst.  The temperature of the partially reacted oil-in-water emulsion is then elevated to from about 50°C to about 80°C and this temperature is maintained for a period of time sufficient to form discrete microcapsules characterized by being substantially impermeable to the hydrophobic emulsion component.
