Abstract: Abstract STEP-PLATFORM OPERATOR      A step-platform operator 17 for transit vehicles for driving a step 19 and a platform 18 between open and closed positions, including a reversible drive motor 42 driving the step and platform through a lever and linkage, providing differential motion between step and platform during the last portion of closing cycle and initial portion of opening cycle, allowing a mechanical interlock between step and platform in fully closed position.  Both platform and step are driven from a single drive unit.  Additionally, the lever and linkage assembly utilizes the weights of the platform and the step to counterbalance each other and allow the use of a low power reversible drive motor to power the system.

Abstract: ABSTRACT OF THE DISCLOSURE           A thermosetting coating composition which may have nonvolatile solids content as high as 60% or greater and which may be employed as an automotive topcoat.  The composition, exclusive of pigments, solvent, reactive and non-reactive diluents and other non-reactive components, consists essentially of: (A)  A binder composition consisting essentially of:      (1) Between about 30 and about 75 weight percent of one or more low viscosity resins selected from hydroxy functional acrylic polymers, hydroxy functional polyethers and hydroxy functional polyesters, each of which (i) is substantially soluble in the solvent of the composition and (ii) has a number average molecular weight of between about 1000 and about 2500; and (2) Between about 70 and about 25 weight percent of one or more crosslinked dispersion polymers each of which is substantially insoluble in the solvent of the composition; and (B)  An aminoplast crosslinking agent in an amount of between about 5 and about 40 parts per 100 parts of said binder composition.  The crosslinked dispersion polymer is prepared by free radical polymerization of 0.5 to 3.5 weight percent of di-, tri- or tetravinyl monomers and 99.5 to 96.5 weight percent of at least one other copolymerizable monoethylenically unsaturated monomer, in the presence of a (i) hydrocarbon dispersing liquid which is a solvent for the polymerizable monomer, but a non-solvent for the resulting crosslinked polymer, and (ii) polymeric dispersion stabilizer which is solvated by said dispersing liquid and associated with said crosslinked polymer so as to maintain a separation between particles thereof, thereby inhibiting coagulation of said particles, wherein polymerization is carried out at elevated temperature such that the dispersion polymer first forms and then is crosslinked.

Abstract: ABSTRACT            A method and apparatuses are disclosed for making shingles. The method consists of clampingly holding a block of material to be cut and conveying such block while it is clamped along a selected path through the clamping mechanism and causing relative movement between two cutting means which are inclined relative to one another to firstly cut a shingle from the block tapering in one direction and followed by a second shingle tapering in the opposite direction.  The apparatus includes means for receiving and clampingly holding blocks as they are fed in sequence thereto and means to feed the block while it is clamped.  The block is fed into the path of two cutting mechanisms and upon relative movment of the clamped block and the cutting mechanisms, the first cutting mechanism cuts first one shingle tapering in one direction and the second mechanism thence cuts a second shingle from the block tapering in an opposite direction, the cutting mechanisms being inclined relative to one another providing the appropriate taper for the shingles cut thereby from the block.  The block clamping and feed mechanism includes two power driven spaced apart conveyors inclined in a direction toward one another in the direction of feed, progressively applying increased clamping forces to the block as it is moved therethrough toward the cutting mechanism.  The conveyors each have a plurality of driven rollers disposed parallel to one another and are driven in synchronism, moving the block incrementally in amounts corres-ponding to the thickness of shingle desired.  The cut shingles are conveyed to an edge trimming apparatus and are moved by conveying means through at least one trimming station having cutting means for trimming the edges of the shingle.  Upstream of the cutting means there is located a scanner that provides information to a computer that processes the information and actuates movement of the trimming saws to trim the edges of the shingle minimizing the amount of waste for each shingle,  Defect cutting devices are also provided for removing defects in shingles and they too are controlled by information provided by the computer.

Abstract: A POSITION CONTROL MECHANISM FOR A VARIABLE DRIVE RATIO PULLEY SYSTEM     Abstract of the Disclosure A variable drive ratio pulley system has longitudinally adjustable pulley halves operated by fluid pressure which acts on piston and cylinder structures operatively connected with the adjustable pulley halves.  The fluid pressure in one of the piston and cylinder structures is controlled by a valve spool responsive to an actuator on which a lever member is pivotally disposed and maintained in abutment with the drive surface on the adjustable pulley half.  The lever member also abuts a control rod which is linearly movable in response to command signals.  Linear movement of the control rod initiates pivoting of the lever member and enforces or permits resultant linear movement of the actuator so that the spool valve is operated to change the pressure level operating on the piston thereby permitting movement of the pulley half resulting in a change of the drive ratio.  The pulley also enforces pivoting of the lever and attendant linear movement of the actuator which causes the spool valve to return to its neutral position when the pulley half has attained the posi-tion demanded by the control rod.

Abstract: ABSTRACT OF THE DISCLOSURE:           A method is disclosed for determining the anti-streptolysin antibody rating in blood or serum samples, comprising the steps of contacting a solution of known con-centration of oxidized 0-streptolysin with a diluted blood or serum sample, allowing the mixture thus obtained to stand at a temperature of from 15°C to 75°C, adding a solution of a reducing agent, waiting the red blood cell sedimentation, checking if haemolysis occurred and checking the condition of a control blank.  If a serum sample is used, it is necessary to add red blood cells thereto prior to the treat-ment with the reducing agent.  It is possible to stop the test to the determination of the antibody threshold and to prosecute testing if the preselected threshold has been exceeded.  A diagnostic kit containing the reagents necessary for the tests is also provided.

Abstract: Abstract Digital signal values are decreased or increased by a predetermined proportion in two steps.  A coarse decrease or increase in steps of 6 dB is first effected by shifting the digital word to be modified in a shift regis-ter (R), after which a fine increase or decrease is realized by adding to or subtracting from the result the result which is once more decreased by shifting it through a number of bit positions.  the second step may be repeated a number of times, each time using the result of the preceding such step as the word operated upon, to eventually give the required answer.  The addition or subtraction is carried out in an adding and/or subtracting device (AD), the additional shift being achieved by means of the wiring between the output (RO1...RO16) of the sift register and the two inputs (AI101...AI116 and AI201...AI216) of the device, and the result replacing the word previously in the shift register, so that no further signal-processing registers are required.

Abstract: ABSTRACT In order to detect the presence of inflammable gas, a detector element is utilized consisting of a coil made with a thin wire of a platinum alloy, enclosed in a Davy cage, the detector is inserted in a resistor bridge circuit and the resistance of the detector changes according to the concen-tration of the inflammable gas so that above a predetermined concentration the bridge becomes unbalanced to such a degree as to give rise to an electric vol-tage signal having an amplitude proportional to the density (per cent) of gas present.  This signal is utilized to electronically control an alarm and/or telesignaling and/or intervention device.  A potentiometer resistor R3 inserted in the bridge circuit, permits the intervention threshold of detector element to be changed.
