Abstract: TRAILER BRAKING SYSTEM               Abstract of the Disclosure An improved trailer braking system for a tractor-trailer configuration is of the type which includes a primary air reservoir on the tractor which supplies an auxiliary air reservoir on the trailer.  A pedal brake actuator on the tractor selectively provides control air from the primary air reservoir on the tractor to a relay valve on the trailer which control air causes air from the auxiliary air reservoir to be directed to the brakes on the trailer.  The improvement includes a secondary source of control air on the trailer in the form of a control air reservoir having a volume significantly smaller than the volume of the auxiliary air reservoir.  The control air reservoir is supplied control air through a first line from the auxiliary air reservoir.  A second line from the control air reservoir goes to the relay valve and includes a check valve therein to only allow the control air to be capable of passing from the control air reservoir to the relay valve.  A normally open first valve element is in the first line and a normally closed second valve element is in the second line.  An electrical solenoid for the first valve element and the second valve element which is actuated by an electrical signal which is produced when control air is provided by the pedal brake actuator closes the first valve element and opens the second valve element to provide control air from the control air reservoir to the control valve prior to control air from the primary air reservoir through the pedal brake actuator.

Abstract: Abstract of the Disclosure Multiple interference sources are independently acquired, tracked and cancelled in a multi-element antenna array where the number of antenna elements n is an integer power of the base 2, i.e. n = 2M where M is the number of sources desired to be cancelled.  The antenna elements are selectively coupled to sets of n/2 phase shifters in respec-tive closed loop control circuits and operate in phase con-trolled sets, one for each interference source.  The phase of the received signal incident on one half of the elements in each set is independently adjusted relative to the other half, for each desired null in a separate control loop, such that for a particular interfering source each antenna element of the set has one corresponding neighboring element in a pair of elements whose phase mutually differs by 180° at the space angle of the arrival of the interference wavefront relative to the axis of the antenna.  This produces a substantially infinite null in the direction of arrival of the particular interfering wavefront and thus complete cancellation of that interfering source is effected.  This null is retained as other interfering sources are independently acquired, nulled and tracked by a respective different set of n/2 elements in the same array.

Abstract: "BEAVER GUARD FOR DRAINAGE CULVERT" ABSTRACT OF THE DISCLOSURE A guard is provided for placement over the upstream opening of a culvert, to bar beavers from entering the culvert and to provide a useful means for dislodging the dam wall which the beavers will build against the guard. The guard comprises a flexible grid consisting of longitudinally extending, spaced apart steel chains, to which are welded a plurality of transversely extending , spaced apart, rigid steel rods.  The width of the grid is sufficient to extend across the culvert opening and bear against the culvert side wall; the length of the grid is sufficient so that it extends along the ground surface in front of the culvert opening, so as to be positioned beneath the beaver dam wall.  Means are provided at the upper end of the grid, for securing it to the culvert or roadway, so that the grid remains hung over the opening.  A long chain extends from the lower end of the grid, which chain is always available to be grasped and which may be attached to a vehicle on the roadway.  This provides a means for rolling up the grid and bringing its load of ac-cumulated debris onto the roadway for disposal.

Abstract: ABSTRACT OF THE DISCLOSURE         Processes are provided for the production of highly useful, sweet, fructose-containing syrups also containing fructooligosaccharides by the partial or substantially-complete hydrolysis of inulin.  The process includes first providing an aqueous solution containing inulin from Jerusalem artichoke tubers or chicory roots.  Then, the warm aqueous solution of inulin at a temperature of, e.g., 40°C. - 70°C., is passed through a column containing a strong acid cation-exchange resin, thereby providing an effluent having a pH of 2.0 - 3Ø  The effluent is then hydrolyzed by heating at a temperature of 70°C. - 100°C., and the so-heated hydrolyzate is passed through a column containing a weak base anion-exchange resin, thereby providing an effluent having a pH of 6.5 - 7Ø  Optionally, after the hydrolysis step, the hydrolyzate at a temperature of 70°C. - 100°C. is decolorized by contact with activated or granular charcoal.  The effluent is then concentrated to a syrup containing less water than the effluent, e.g., one containing 40% - 70% solids.  The sweet fructose syrup containing oligofructans can be used as truly "health" sweetener, particularly ideal for elderly people and diabetics.  The pulp obtained after juice extraction is rich in protein and can be used as animal feed.

Granted: 1986-01-14
Abstract: Concerning pedal driven front wheel drive cycles we know that the front wheel is not equiped with a crank gear.  Also, there is no sprocket freewheel. Consequently, there is no possibility for speeds on those cycles.  In the present invention, there is a crank gear made with at least one chainwheel, an intermediate  cogwheels mounting and a cycle wheel equiped with a sprocket freewheel.  The front wheel axle is rotating by means of cranks with pedals and this movement is transmitted to the wheel freewheel using chains and front fork intermediate cogwheels. The gear changes possibilities of that front wheel permit the manufacture of front wheel drive racing cycles.  The front wheel is also steerable by means of a handlebar.  The recumbent position adopted by the driver of this pedal driven front wheel drive racing cycle allow better performance than any conventional racing cycle.

The receptacle consists of an upper body member provided therein with a rotatable table at a lower portion thereof for detachably and non-rotatably mounting thereon the double-walled vessel and a lower body member detachably connected to the upper body member and provided therein with driving means detachably connected to the rotatable table for rotating the same.  Since the double-walled vessel is rotated by the driving means of the heavy weight located at the lower part of the receptacle, while the agitating blades are held stationarily by the cover member, it suffices to merely locate the double-walled vessel on the rotatable table before the cover member is fitted to the receptacle for the operation of the cevice, the operation of the device is largely facilitated and the operation is rendered to be stable, and the cleaning of the upper body member and the storage both of the body members are facilitated, because both the body members are detachable from each other.

Abstract: ABSTRACT            An interference technique is used to measure the state of polarization of a quasi-monochromatic light beam.  Two quasi-monochromatic radiations with slightly different optical frequencies are generated.  One radiation is converted into a 45° linearly polarized radiation, whilst the other presents the polarization state imposed by a body under test.  In each radiation, horizontal and vertical polarization components are separated, and the horizontal and vertical components are then respectively recombined into two different beams each comprising radi-ations at both frequencies, polarized in the same plane. Beats between the two components in each beam are generated and used to generate two electrical signals in the radio frequency range, from which information is ex-tracted as to the relative phase and the amplitude of the two components of that radiation whose polarization is imposed by the body under test.
