Abstract: ABSTRACT OF THE DISCLOSURE Title:  "Improvements in or Relating to Flueric Partial Pressure Sensors"     A flueric partial pressure sensor includes a flueric bridge having two bridge legs adapted for sensing a reference-gas and sample-gas mixture. A linear resistor and an orifice resistor are incorporated in each of the bridge legs which are conjoined to discharge from a single outlet.  The resistors are arranged to provide an asymmetric balance of the flow rates through the bridge legs.  The asymmetric balance is selected so that in operation a constant pressure output signal is generated for a chosen partial pressure of a constituent gas of the sample-gas mixture in varying absolute pressure conditions such as changes in altitude.  Respective pressure signal outlets connected one with each bridge leg at a position between the linear resistor and the orifice resistor are used to effect control of a flueric laminar flow proportional amplifier.

Abstract: ABSTRACT           An apparatus is disclosed that fixes powder images to a receptor by means of pressure.          Pressure fixing images to a receptor, such as paper, by means of smooth steel rolls produces copies that have shiny image and background areas.          The present invention overcomes this problem by providing a pressure fixing apparatus having a first or top roll to contact the surface of the receptor bearing the powder image, and a second or bottom roll to contact the opposite surface of the paper.  The top roll has an irregular, non-compliant surface bearing numerous randomly sized, domed projections.  The bottom roll has a compliant surface.  The rolls have skewed longitudinal axes with respect to each other and contact each other when no receptor is passing between them.

Abstract: PHASE TOLERANT BIT SYNCHRONIZER FOR DIGITAL SIGNALS     Abstract A bit synchronizer for digital data signals capable of tracking phase errors of up to ? 180° without loss of lock.  An input data signal is squared and then applied to a pair of D-type flip-flops.  The flip-flops are alternately driven by a clock signal generated by a voltage controlled oscillator in a phase-locked loop.  me flip-flops cause the input data to be shifted 0° and 180°, respectively, with reference to the clock signal.  The flip-flops are cross-coupled to a pair of exclusive-OR gates, in a manner such that as the phase error between the input signal and the clock signal increases or decreases, the pulse width out of one gate varies proportionately while the output of the other gate is a pulse which is always one-half the clock signal period.  The phase relationship of the pulses out of the gates switch 180° as the phase error traverses the 0° point.  me outputs of the gates are summed to provide a measure of the phase error between the clock signal and the input signal and to produce a net control voltage representative thereof.  me control voltage is applied to the oscillator to cause the frequency and phase of the clock signal generated thereby to be synchronous with that of the input signal.  In the absence of bit transitions, the phase-locked loop is biased to seek the tuned bit rate.  The described arrangement permits tracking phase errors over a ? 180° range without loss of synchronization.

Abstract: Abstract of the Disclosure It is known to manufacture an osteosynthesis implantate, such a bone nail or plate, in combination with a receiving coil and electrode connections to form an electro-implantate.  The coil and electrodes provide a small electrical voltage across the implantate and surrounding tissue to stimulate the healing process.  It is also known to convert osteosynthesis implantates into electro-implantate by the addition of belt-like or loose pick-up type coil elements.  The present invention relates to an attachment element consisting of a body support formed to attach to an ordinary implant-ate and which includes at least one induction coil and two electrodes, one of which is connectable with a conductive portion of the implantate, the other being exposed to bone or soft tissue of the patient.  The present invention may be applied to the implantate so that it can be converted into an electro-implantate during the progress of an operation with greater ease and less complexity then can either the belt-like or pick-up coil elements.  Further, the result will be a fully equivalent and effective substitute for a pre-manufactured electro-implantate but at substantially less cost.

Abstract: ABSTRACT OF THE DISCLOSURE:        A concrete shielding housing for receiving and storing a transportable fuel element container which is suitable for storage and filled with spent nuclear reactor fuel elements.  The outer dimensions of the fuel element container are somewhat smaller than the clear interior dimensions of the concrete shielding housing.  The concrete shielding housing includes a pallet-like base which can be moved about from one location to another with the aid of a suitable vehicle such as a fork-lift truck.  The housing also includes the concrete shielding wall placeable upon the base, and a cover which can be placed atop the upper end of the concrete shielding wall.  At least one air inlet opening is provided at the lower region of the concrete shielding housing and, at the upper region thereof, there is provided at least one air outlet opening.  The plan profile of the base is smaller than the plan profile of the concrete shielding wall so that the surface water which accumulates on the concrete shielding housing from falling rain can run off to the ground without hindrance.  In addi-tion to the advantageous runoff of the surface water from the concrete shielding housing, this configuration permits the transport corridors in the container storage area to be made narrower.
