Abstract: Abstract of the Disclosure An apparatus for controlling fluid flow to a steering motor and an auxiliary apparatus is capable of smoothly changing between conditions in which it directs relatively small and relatively large flows of fluid to the auxiliary apparatus.  The apparatus includes a priority valve assembly having a valve member positioned in accordance with variations in the demand for steering fluid.  A land on the valve member cooperates with a fixed valve surface to form a variable size orifice through which fluid flows to a steering controller.  A second land on the valve member cooperates with a fixed valve surface to form a variable size main auxiliary flow control orifice through which all of the fluid flow to the auxiliary apparatus is directed during relatively low fluid flow rates to the auxiliary apparatus.  A third land on the valve member cooperates with a fixed valve surface to form a second variable size flow control orifice through which additional fluid flow is directed to the auxiliary apparatus during relatively high fluid flow rates to the auxiliary apparatus.

Abstract: ABSTRACT          A chain saw safety braking assembly includes a sensing arm pivotally mounted to the housing and having a protrusion.  A portion of the sensing arm is located in front of the gripping handle and is arranged to move from a first position to a second position in response to being struck by an appendage of the operator.  A flexible brake band is disposed around the peripheral surface of a brake drum, and includes a first end anchored to the housing and a second end coupled to the sensing arm protrusion, such that when the sensing arm moves from the first position to the second position the flexible brake band is moved from a position free of the brake drum to a frictional braking relationship with the brake drum.  A latch is rotatably mounted to the housing and is adapted to releasably engage the protrusion on the sensing arm.  A spring anchored to the housing cooperates with the latch such that the latch yieldably holds the sensing arm in either the first or the second position. Thus when the sensing arm is struck, it will move from the first position to the second position stopping the chain movement.  Additionally, an acceleration sensing assembly may be incorporated to sense acceleration of the saw, again typically due to kickback, and stop the chain should the acceleration rise above a preset level.

Abstract: Abstract:   Automobile towing apparatus for mounting on a tow truck has a pivotal boom that projects rearwardly from the truck.          The boom has a forward portion extending along the truck, the rear end of this forward portion being connected to a downwardly extending portion located just beyond the rear of the truck.  The lower end of the downwardly projecting portion supports a rear portion that is extensible and in turn supports a transverse beam, on the ends of which there is mounted a pair of vehicle lifts for engaging and lifting the wheels of a disabled vehicle.  This beam has limited rotation about a front to rear horizontal axis to accommo-date loading a vehicle standing on a sideways slope.  The boom is pivotable, optionally, about a pair of transverse horizontal axes located at the respective ends of the forward boom portion.  This arrangement enables the vehicle lifts to be moved among (a) a normal, horizontal loading position close to the ground, (b) an elevated towing position and (c) a down-sloped position for loading a disabled vehicle standing on ground sloping away from the rear of the tow truck.  The vehicle lifts are freely upwardly pivotable to facilitate loading a vehicle standing on ground sloping upwards from the rear of the truck.  The beam is also mounted for rotation about a vertical axis to accommodate towing around a corner, this movement being inhibited when loading.  Brake bars can be lowered when towing to provide added safety in the event of the truck losing control.  The resultant apparatus is more versatile than previous arrangements in relation to loading a disabled vehicle standing on a slope, and is also safer and more foolproof to operate.

Abstract: ABSTRACT      The invention concerns a device for the automatic supplying of fish uniformly aligned with respect to their belly-back and head-tail position to fish processing machines.  The object of the invention comprises the improvement of a known construction including a feeding channel, a positively effective conveyor for the fish, an uprighting station with a toothed roller and a guiding element as well as a discharge channel.  It is the objective to make the known device suitable for processing a greater quality tolerance.  To achieve this it is suggested that the conveyor is deflected out of engagement only shortly upstream of the uprighting station which effects the engagement of the head flank of the fish head on the bottom surface of the feeding channel which is neces-sary for a troublefree righting of the fish.

Abstract: ABSTRACT OF THE DISCLOSURE           A document handling system in which an air permeable belt advances documents to an imaging station of a copying machine. The belt reflects light rays transmitted thereto except in grooved areas which have been rendered at least partially transmissive to light. These grooved areas contain vacuum apertures in the belt. Semi-circular air channels in the vacuum plenum in concert with the belt apertures provide a means to hold the document to the belt. Light rays transmitted through the partially transmis-sive grooved areas are reflected from the air channel to back-illuminate the aperture/groove area thereby reducing background shadows associated with these aperture areas. A vacuum system is in communication with the belt for retaining the documents thereon. The vacuum system is arranged to receive the light rays transmitted through the belt and diffusely reflect the light raysincident thereon back through the belt.

Abstract: Abstract of the Disclosure A system for processing of multifrequency input signals to provide a Fourier transform output is provided which can, for example, partition a wide input frequency band into a number of narrow bands and concurrently detect the presence of one or more signals of different frequency in the input.  An array of input wave energy transducers is energized with the broadband signal, and by virtue of progressive shifting of the transducers relative to the propagating medium (such as a surface acoustic wave sub-strate) generates one or more composite wavefronts dispersed at frequency dependent angles.  An array of output trans-ducers are disposed along a focal region, each responding to wave energy within a specific frequency range received at its location due to dispersion of the composite wavefront.          Such systems preserve phase coherence while responding to multiple input frequencies, but are compact and mass pro-ducible at relatively low cost.

Abstract: ABSTRACT OF THE DISCLOSURE           A magnetically operated AC switching device, such as  an  AC  electrical  contactor,  is  operable  with  a delay-on-dropout  feature  to  permit  safe  shutdown  of equipment energized therethrough in case of power failure.          The device includes an AC pickup winding which is energizable from an AC power source and a DC holding winding which is electrically connected to a rectifier for energization of the holding winding with DC power from the AC source.  A capacitor is also electrically connected to the rectifier in parallel with the holding winding for energization with DC power from the AC source.   Upon energization of the device,  the AC pickup winding moves  fixed and movable contacts of the device into engagement, and the DC holding winding maintains them in engagement. The AC pickup winding can remain energized without burnout; and upon power dropout the capacitor supplies DC power to the holding winding for an instant to provide a slight delay in the separation of the contacts.

Abstract: ABSTRACT OF THE DISCLOSURE An internal combustion engine piston and combustion chamber are configured to produce controlled reaction of the fuel supplied to the working chamber with prolonged supply of air to the reaction zone over the combustion/expansion part of the engine operating cycle. After an axially stratified charge, with little or no fuel near the piston working face, is established in the working chamber of the engine, part of the air is transferredduring the compression of the charge into an air chamber near the working face of the piston which communicates with the working chamber through a restricted gap orifice. The air chamber is configured to resonate at the same frequency as the frequency of the combustion waves in the manner of a Helmholtz resonator, with a specific gap dimension and air chamber volume that is mathematically related to gap area, the speed of sound in the air chamber at the autoignition temperature of the compressed charge in the working chamber, the axial length and radial width of the gap orifice, and the natural Helmholtz resonant frequency of the gas in the air chamber. The resonating gases in the air chamber, moreover, induce closed organ pipe resonance in the working chamber at least one fundamental frequency while the piston is between top and bottom dead center positions. A system for controlling air to fuel ratio is also included to cause the combustion cycle to operate at the maximum attainable "Run Quality Index" (a defined term indicative of practical efficiency) for the specific engine. The piston and working chamber are also configured to produce a dynamic variable compression ratio by preventing total pressure equalization between the working and air chambers above a certain selected engine speed range by causing choked flow to exist between the working and air chambers above said speed range.

Abstract: ABSTRACT            Echo cancellation is carried out on a received demodulated analog signal.  The apparatus comprises an analog transversal filter, a computing circuit for generating the direct coefficients al to ar and, eventually, feedback coefficients b2 to bm of an analog transversal filter.  The input of a computing circuit is connected to the input of an analog transversal filter.  The computing circuit is comprised of an analog-to-digital converter, whose output is connected to a self-adaptive digital transversal filter.  The values of the digital transversal filter multiplication coefficients are applied, as coefficients, to the multipliers of the analog transversal filter.  The optimization criterion is that of the mean quadratic error.  The convergence algorithm is that of the gradient.  The iterative correction may be carried out at each step on the digital transversal filter's group of coefficients. Or, it can be carried out cyclically on each of the digital transversal filter's coefficients.  Variations Or the self-adaptive digital transversal filter are described.
