Abstract: SYSTEM FOR CONTROLLING DISTINCT DEVICES             IN A THEATER               Abstract of the Disclosure A system for controlling a plurality of distinct devices in a theater displaying a projected motion picture or other visual program and having a multichannel sound signal contained on a moving film or other type strip, which system has a memory unit for storing groups of digital control signals for operating the distinct devices, each forming a channel, in a selected man-ner during a selected portion of the moving strip.  This system has means for selecting one of the groups of the digital control signals for a selected portion of the visual program and means independent of the strip for causing the stored digital control signals of the selected group to be outputted in a time sequence corresponding to the selected portion of the visual program. There is provided an improvement wherein the selecting means in-cludes a digital code recorded on the moving strip and the code comprises a constant, repeating synchronization digital code and a unique digital time code corresponding to the selected group of digital control signals to be outputted in a given time sequence by using hardwired counters for processing the selected digital signals.

Abstract: ABSTRACT         Disclosed herein are improvements in a recoil reducing system of a gas gun which create pulses in a liquid medium by introducing therein gas under high pressure.  The release of high pressure gas from the barrel of such a gas gun causes recoil of the barrel.  To reduce recoil, a reaction plate is attached to the barrel by metal rods so that the high pressure gas will impinge upon the reaction plate before escaping into the medium, and the force exerted on the reaction plate by the impinging gas will at least partially balance the force of recoil.  In a preferred embodiment of this invention, a layer of shock absorbent material is interposed between the reaction plate and the impinging gas to absorb some of the energy of the gas.  Flexing of the metal rods is thereby reduced and the life of the rods is extended.  Alternatively, the flexing of the rods is reduced by connecting each rod to the reaction plate through a chain link type of connection comprising two rings, each ring passing through the other ring.

Abstract: Abstract of the Disclosure:   The invention provides a novel method for the racemization of an optically active isomer, particularly the d-isomer, of a tetrahydroisoquinoline derivative of the formula:                            (I) wherein Ar is a trimethoxyphenyl group.  This enables the enantiomorph (i.e. the d-isomer) which remains after sub-jecting a racemic modification of a tetrahydroisoquinoline derivative (I) to optical resolution and removing the desired optically active species (i.e. the ?-isomer), to be utilized.          The racemization method comprises the steps of (a) acylating an optically active tetrahydroisoquinoline (I); (b) reacting the resulting optically active N-acyltetrahydroisoquinoline derivative (II) with an aralkyl halide; (c) hydrolyzing the resulting optically active N-acyltetrahydroisoquinoline derivative having protected hydroxy groups (III); (d)  (1) subjecting the resulting optically active tetrahydroisoquino-line derivative having protected hydroxy groups (IV) to a halogenation reaction, followed by a dehydrohalogenation reaction, or (2) subjecting the optically active compound (IV) to nitrosation, followed by removal of hyponitrous acid; (e) reducing the resulting dihydroisoquinoline derivative having protected hydroxy groups (V); and then (f) subjecting the resulting racemic tetrahydroisoquinoline derivative having protected hydroxy groups (IV) to catalytic reduction to give the desired racemic modification of a tetrahydroisoquinoline derivative (I).

Abstract: AN OPTICAL SENSOR FOR FOCUSING CONTROL     Abstract of the Disclosure An optical sensor for delivering error signals in order to control focusing of a lens on a movable recording medium or optical memory and more particularly a videodisk comprises a laser for producing a beam which is focused at a point S1.  The divergent beam which pro-ceeds from the point S1 is reflected from the face AB of a prism and is focused at a point S2.  If the point S2 is located in the plane of the movable recording medium or so-called memory plane, the beam reflected from the memory plane is autocollimated and passes back through the focusing lens.  A part of the beam enters the prism through the face AB, then emerges through the face AC and a circular light spot is formed in the plane corresponding to the circle of least confusion. If the point S2 is not located in the memory plane, the light spot is deformed and these deformations are detected by four juxtaposed cells placed in the plane of the circle of least confusion.

Abstract: FLEXIBLE CROP HARVESTING HEADER     ABSTRACT OF THE DISCLOSURE         A crop harvesting header, attachable to a combine to sever standing crop and initiate the crop harvesting process, is disclosed wherein both the cutterbar and the floor of the header are somewhat flexibly constructed to follow the contour of the ground and harvest low growing crops.  A counterbalancing force for the cutterbar is provided by leaf spring members spaced along the width of the header.  These leaf spring members are connected to a lower portion of the header in such a manner as to enable the amount of counterbalancing force supplied to the cutterbar to be variable by changing the number of leaf spring members exerting a counterbalancing force, either by increasing the number of locations that the leaf spring members are connected to the header frame or by increasing the number of leaf spring members at each location.  Attachment ribs pivotally interconnecting the cutterbar and the header frame provide stability against side-to-side movements by the cutterbar relative to the header frame without subjecting the leaf spring members to such forces and without requiring extra frame members to prevent the side-to-side movements of the cutterbar.

Abstract: ABSTRACT OF THE INVENTION      Methods are provided for selectively consolidating sand grains within a subterranean formation.  First an acidic salt catalyst such as ZnCl2 is injected into the subterranean formation, wherein the acidic salt catalyst is adsorbed to the surface of the sand grains.  Next a polymerizable resin composition such as furfuryl alcohol oligomer is introduced into the well formation.  Poly-merization of the resin occurs upon exposure to the ele-vated well temperatures and contact with the acid salt catalyst adsorbed to the sand grains.  The polymerized resin serves to consolidate the surfaces of the sand grains while retaining permeability through the pore spaces.  An ester of a weak organic acid is included with the resin compositions to control the extent of a polymerization by consuming the water by-product formed during the polymerization reaction.

Abstract: Abstract Diaphragm Pump The present invention provides for an improved diaphragm pump having two material pumping chambers. The material pumping chambers are operated by two work-ing fluid chambers which are separated from the material pumping chambers by two diaphragms.  The diaphragms are interconnected to provide that the two material pumping chambers alternatively receive and discharge the mater-ial to be pumped.  A control valve controls the stroke reversal of the improved diaphragm pump.  The control valve is actuated by the pressurized working fluid which is being discharged from a pressurized fluid chamber. Further valving provides for a portion of the pressurized working fluid being discharged from a pressurized fluid chamber to be reused and introduced into the exhausted fluid chamber to initiate expansion of the exhausted fluid chamber.  The pre-pressurization of the exhausted fluid chamber reduces the amount of source air required at the beginning of the stroke.
