Abstract: ABSTRACT OF THE DISCLOSURE          Engine diagnostic apparatus for displaying on a cathode ray tube the voltage conditions existing at each of the spark plugs which apparatus is intended for use with ignition systems in which the voltage pulses applied to the spark plugs are of such short duration that a cathode ray tube will not properly respond to the changes of voltage.  The apparatus is effective to successively charge a capacitor to a value corresponding to the value of each voltage pulse and the voltages across this capacitor are used to control the vertical defection of the cathode ray tube.  At the end of a first period of time following a voltage pulse, the capacitor is shorted.  The capacitor is maintained shorted for a longer period of time less than the time between successive pulses so as to avoid undesired charging of the capacitor as a result of transient condi-tions.  The time constant of the charging circuit for the capacitor is less than the duration of the voltage peak so that the capacitor is substantially fully charged during the voltage peak.

Abstract: Abstract Of The Disclosure A clasp for an article of jewelry or the like of the type having a latch member engageable with a keeper member for fasten-ing the clasp.  The latch member has a resiliently depressible hook portion disposed for movement from a normally extended position to a flexed position.  The keeper member comprises a housing having an open end through which the hook portion of the latch member may be inserted or withdrawn when the hook portion is in its flexed position.  The housing also includes an apertured wail located to receive the hook portion for engaging the latch member within the housing and permitting the hook portion to move to its extended position for fastening the clasp.  The hook portion extends beyond the aperture in the housing wall when the latch member is engaged within the housing, and terminates in an end portion overlying an edge portion of the housing wall forming the periphery of said aperture when the latch member is moved in the direction of withdrawal from the housing.  The overlying relation of the hook end portion to the housing wall prevents the hook portion from moving to the flexed position to inadvertently unfasten the clasp.  The design of the hook portion is such to reduce the likelihood of it  being  sheared off when the clasp members are engaged and under tension.  At such time as it is desired to unfasten the clasp, the latch member is moved in the direction of insertion in said housing to align said hook portion with said aperture and the hook portion is then moved to its flexed position to permit the latch member to be withdrawn through the open end of the housing.

Abstract: ABSTRACT OF THE DISCLOSURE:     This invention is concerned with an apparatus for chopping forest and bog  stumps and snags under field conditions so as to render the chopped wood suitable for transportation, wherein the chopping is effected by applying pressure which breaks the wood material charge that has been brought in one way or another into the space defined by a main blade and intermediate blades and by a backing plane and a bottom.  This apparatus com-prises a frame defining a chopping space, a generally vertical wall bounding one side of the chopping space and a cavity below the wall and chopping means reciprocably movable back and forth in the space in a direction perpendicular to the vertical wall.          The chopping means comprise a generally horizontal main blade, at least two intermediate spaced blades extending downwardly from the main blade and inclined with regard to each other so that the space between the intermediate blades widens in a downwards direction, and a bottom member secured to the blades and extending mainly between the blades and the vertical wall when the chopping means is in a rearward position.  The bottom wall moves into the cavity below the vertical wall during forward motion of the chop-ping means.  The apparatus according to the invention also comprises means for supporting the chopping means and for effect-ing its reciprocating motion.

Abstract: ABSTRACT OF THE DISCLOSURE 4-.beta.,.beta.-dichlorovinyl (or dibromovinyl)-3,3-dimethyl-butyrolactones are prepared from 1,1-dichloro (or dibromo)-4-methylpenta-1,3-diene by reacting with an acid of formual CH2R.CO2H in presence of a salt of a metal in one of its higher valency states, especially manganese (III), cerium (IV), or vanadium (V).      Higher yields are obtained in the presence of the anhydride of the acid and of the sodium or potassium salt of the acid.  Treatment of the lactones with an inorganic acid halide opens the lactone ring with formation of the corresponding 4-haloacid halide, which with alcohols affords the corresponding 4-haloacid ester, cyclised by bases to a 3-.beta.,.beta.-dichloro (or dibromo)vinyl-2,2-dimethyl-cyclopropanecarboxylic ester, intermediate for insecticides such as the m-phenoxybenzyl ester.

Abstract: ABSTRACT       A system for controlling the hydrogen/hydrocarbon mole ratio in a continuous hydrocarbon conversion process wherein the hydrocarbonaceous feed stock is catalytically reacted in a hydrogen atmosphere.  Applicable to both hydro-gen-consuming and hydrogen-producing processes, in which the reaction zone effluent is separated to provide a liquid product phase and a hydrogen-rich vaporous phase, a portion of the latter being recycled to the catalytic reaction zone, the control system affords improved overall operation of the particular process in addition to increased catalyst activity and stability.  Analyzers are utilized to monitor composition characteristics of the charge stock and liquid product, and the hydrogen concentration of the vaporous phase recycled to the reaction zone.  Representative output signals are transmitted to comparator/computer means which compores the rate of change and actual values of the compo-sition characteristics and the hydrogen concentration, and generates additional output signals which are utilized with-in the control system for regulating the hydrogen/hydrocar-bon mole ratio of the combined charge to the reaction zone.

Abstract: ABSTRACT OF THE DISCLOSURE         A hydraulic jack, suitable for use as an out-rigger support for a mobile crane, has a cylinder with a piston slidably received therein.  Projecting from the piston is a rod that extends axially outward of the cylinder for supporting a load.  The rod is externally threaded and a worm wheel nut is internally threaded to fit upon the rod.  The nut is held in a fixed, axial position relative to the cylinder, and this nut must rotate on the rod to enable the rod to travel inwardly or outwardly of the cylinder.  A rotatable worm is threaded to mesh with worm engaging gear teeth on the periphery of the worm wheel nut.  Preferably, the thread on the worm has a helix angle with a self-locking characteristic, but the helix angle of the threads between the worm wheel nut and the piston rod is greater than the angle of friction so that there are no self-locking characteris-tics.  The worm is driven by a hydraulic motor, that is connected with the cylinder in a hydraulic circuit, and a common control valve regulates the operation of both the cylinder and the motor.                             -1a-
