Abstract: Protection device adapted for use with a vertical blade cutter comprising a cutting blade. The device comprises a moveable plate for covering the blade and protecting against accidental contact with the blade. The moveable plate is adapted to be retracted during cutting and is further adapted to be otherwise lowered in front of the blade. A bar is provided which is adapted to slide in a guide adapted to be attached to the cutter. The moveable plate is mounted on the bar. A plate support is journaled onto the guide. A rotatable wheel is attached to the plate support. The rotatable wheel, when brought into contact with the bar while rotating, is adapted to raise the bar and moveable plate and whereas disengagement of the wheel from the bar causes the moveable plate to be lowered in front of the blade by virtue of its own weight and that of the plate.

Abstract: ABSTRACT     A bus-oriented optical communication system operating in the frequency multiplex mode is provided.  Pluggable couplers and colour coders and decoders are proposed which are designed as self-collimating optical elements.  The couplers consist of a self-collimating part included in the bus and a counter-part connected thereto.  Without the counterpart, the coupler, by total reflection, causes the light exiting from the bus to be reflected back to the bus practically without loss.          The connected counterpart includes a frequency-selective means, such as an interference filter, and couples the desired wavelength band out of the bus by frustrating the total reflection.  The frequency coders and decoders also consist of self-collimating components which are either connected via couplers or which may be directly included in the bus The colour coders preferably use reflection gratings as dispersive elements, a colour coder included in the bus consists of two halves with engaging reflection gratings.          The reflected light is split in accordance with frequency response of the gratings and the passing light is not split.

Abstract: APPLICATION FOR LETTERS PATENT for PROCESS AND APPARATUS FOR EFFECTING CARBURETION     ABSTRACT OF THE DISCLOSURE    The disclosure relates to a process and apparatus for effecting carburetion to provide an air and vaporized fuel mixture for operating an internal combustion engine, or the like.   A vaporizing and mixing chamber is juxtaposed on an intermediate chamber which, in turn, is juxtaposed on a holding chamber.   Ambient air is admitted to the intermediate chamber and fuel at ambient pressure is admitted to the holding chamber. Metering means is provided for metering air flow from the intermediate chamber into the vaporizing and mixing chamber and for metering the flow of liquid from the holding chamber.  The fuel flows axially to a jet orifice into the confluence of a plurality of air jet passages directed counter to the flow of fuel to the jet orifice and the resultant mixture of air and liquid fuel is aspirated in a column into the vaporizing and mixing zone.   A whirling motion is imparted to the air-liquid fuel mixture in the column so that, when it reaches the vapor-izing and mixing column, it flies out by centrifugal force into the vaporizing and mixing chamber.   The air jet orifices are directed at an acute, oblique angle, so that the jet orifices are an annular loci at the base of the column and the fuel is jetted up into the center of the loci.   A turbulent vortex is thus established at the confluence which promotes disintegration of the fuel into tiny globules and dispersion of these globules into the air.

Abstract: Abstract of the Disclosure A hydraulic power pack for supplying hydraulic fluid under pressure for operating apparatus such as hydraulic work-over units used in servicing oil and gas wells.  The power pack provides substantially constant hydraulic power input to the driven apparatus over a wide range of pressures and flow rates.          The power pack includes a constant speed engine, a gear box driven by the engine, a bank of positive fixed displacement pumps of varying sizes driven by the gear box and having dis-charge ports connected with a common discharge manifold, a hydraulic fluid reservoir, an intake manifold between the reservoir and the pumps, a return line to the reservoir, a recirculating line connected between the discharge from each of the pumps and the return line, and an unloading valve in each of the recirculating lines operable responsive to the pressure in the discharge manifold for recirculating each of the pumps to the reservoir at a predetermined pressure value.  Each of the unloading valves is set to open at a different pressure ranging from a minimum at which all of the pumps discharge to the discharge manifold to a maximum above which all of the pumps recirculate to the reservoir.  The unloading valves are set to operate in graduated sequence with all the pumps dis-charging to the manifold below a first minimum pressure with one pump automatically recirculating to the reservoir as each predetermined pressure increase increment is reached until at the last operating stage only a single pump is discharging to the manifold and above that stage all pumps recirculate to the reservoir.  The power pack permits operating a hydraulic work-over unit automatically providing maximum lifting force at a minimum speed to minimum lifting force at a maximum speed.

Abstract: Pressure Balanced - Constant Engagement Force Seal Abstract of the Disclosure A seal apparatus for sealing between relatively rotatable structures is provided and has a pair of seal rings which are engageable at axial sealing face portions.  Axially facing surfaces of the first seal ring are arranged such that fluid pressure acting thereon biases it in a first direction.  Axial positioning and circumferential retention of the second seal ring is provided by an elastomeric toric which is arranged radially between the second seal ring and a retaining ring structure which constitutes a part of the relatively rotatable structure.  Axially facing surfaces of the second seal ring and the sealing toric have areas in the axial direction which cause the second seal ring to be pressure balanced in the axial direction by fluid pressure exerted thereon.  A Belleville spring is arranged axially between the retaining ring structure and the second seal ring and is prestressed to provide a constant axial force against the second seal ring.  The toric is engaged only on its radial extremes and thus may readily roll about its circular, central axis, but, when suitably radially compressed, will not readily slide circumferentially or axially relative to the second seal ring and retaining ring structure.
