Abstract: ABSTRACT A vibratory seismic energy source capable of generating signifi-cant energy over a broad frequency band.  The vibrating baseplate and asso-ciated structure are designed for minimum size and weight, while retaining the structural strength to permit high actuator forces. The weight of the transport vehicle is applied to a substantially horizontal hold-down plate that is interposed between the piston-cylinder assembly and the baseplate. This horizontal plate is coupled to the baseplate through resilient means having compliance such that dynamic motion of the baseplate is decoupled from the hold-down plate and transport vehicle.

Abstract: INVENTION:  FUEL INJECTION SYSTEM WITH AUGMENTED TEMPERATURE           SENSITIVE FUEL ENRICHMENT FOR TRANSIENT ENGINE LOADS          INVENTOR:   E. DAVID LONG                      Abstract of the Disclosure A fuel injection system for a spark ignited, internal combustion engine employs sensors which measure engine operating parameters to control the duration of actuating pulses applied to at least one fuel injector.  One of the sensors measures engine temperature and the pulse duration is increased at lower engine temperatures to compensate for the lower volatility of the fuel at such lower temperatures.  The output of a manifold vacuum sensor is differentiated to derive a signal proportional to the fate of increase of engine load and that is used in com-bination with the engine temperature sensor to increase the duration of an injector actuating pulse in amounts proportional to the rate of increase of engine load.  The amount of increase in duration of the pulse varies inversely with engine tempera-ture.  This allows the enrichment of the fuel charge which normally occurs as an inverse function of engine temperature to be maintained at a level which may produce a leaner steady state air to fuel ratio during engine warm-up and to provide additional enrichment of the fuel charge during periods of increase transient engine load to provide reduced exhaust emissions during warm-up without stalling.

Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure describes a process for the preparation of a light-sensitive silver halide photographic material comprising a support, a silver halide emulsion layer and a non-light-sensitive hydrophilic colloid layer which consists essen-tially of a plurality of layer elements.  The process comprises incorporating, into at least one of the elements, oil particles so that the oil particle density of the outermost layer element, if present, may not be the highest among the oil particle densities of the elements.  This process enables to obtain a non-adhesive light sensitive material, which does not cause any so-called sweating.  The process enables a reduction in the amount of a surface active agent or an antistatic agent to be added.  Finally, the light-sensitive agent produced by this process shows less variation with time in surface properties.          Light-sensitive silver halide photographic material produced by this process.

Abstract: Abstract of the Disclosure A method for production of fibrous sheet material com-prising dispersing fibres in a gas stream to obtain a gas--fibre stream, supplying the gas-fibre stream onto a flat screen, removing gas from the gas-fibre stream through said screen to form a fibrous sheet layer thereon, and its subsequent treating to obtain a fibrous sheet material, a part of gas being removed from the gas-fibre stream prior to supplying it onto the flat screen, so as to bring the fibre concentra-tion up to 20-500 g/m3.  The concentration is chosen in accor-dance with the kind and properties of fibres.  Simultaneously transversal pulsations induced in the gas-fibre stream in the course of its movement are damped.  An apparatus for carrying out this method comprises a slot nozzle having side walls which are normal to converging frontal walls, its inlet ope-ning being connected with a means for dispersing fibres in a gas stream, while its outlet opening is connected with a chamber, a flat screen adapted to form a fibrous layer thereon, mounted under said chamber, and a suction box arranged under-neath the flat screen, wherein the side walls of the slot nozzle are in parallel relationship with respect to each other, a means for removing a part of gas from the gas-fibre stream is arranged in the chamber under the outlet opening of the slot nozzle, and the chamber is provided with branch pipes for gas exhaust, mounted substantially in the upper portion of the chamber.

Abstract: Abstract of the Disclosure Digital position error signals from a position detector and a track increment generator are summed and applied to a compensator which is responsive to these signals during the sampling of servo sectors on the tracks of a magnetic disk of a magnetic disk store to regulate the position of a magnetic head for track selection and track following.  Track selection is effected with an acceleration phase, a constant velocity phase, and a deceleration phase, and overshooting of the magnetic head at the ends of the acceleration and deceleration phases is avoided by digital modification signals read out, from read-only memories in the track increment generator, to the compensator.          The digital position error signal from the track increment generator can be combined with the output of a track crossing detector.

Abstract: ABSTRACT OF THE DISCLOSURE      A fluid injection assembly of a type designed to inject fluid into a flowing stream of liquid at a predetermined, adjustable rate without the assistance of an outside power source other than the line pressure of the flowing stream itself.  The assembly includes a casing having the fluid to be injected disposed therein and at least partially contained by a flexible membrane.  Liquid from the flowing stream is partially disposed in fluid communication with the interior of the casing so as to flow in surrounding relation to a portion of the flexible mem-brane whereby pressure exerted thereon will aid in dispensing of the injection fluid therefrom.  An open end of the dispensing line for the injection fluid is disposed within the flowing stream so as to create a negative pressure further aiding in removal of the fluid from within the casing.  A liquid flow rate meter is provided so as to give a constant, visual indication of the rate of flow of the liquid into which it is desired to inject a fluid.  A similarly constructed fluid injection meter is pro-vided so as to permit visual observation of the rate of fluid injection.  A dispensing valve is provided to allow regulation of the rate of injection of fluid into the flowing stream of liquid.
