Abstract: Abstract of Disclosure A multipolar electrosurgical device is describ-ed for use in neurosurgery or through the channel of an endoscope or other precision surgery procedures.   The device is formed with an insulative probe body, which, in the described embodiment, is sized to pass through a channel of an endoscope to enable the electrocoagula-tion of blood vessels such as may be needed in the treatment of a gastrointestinal ulcer.The probe body is provided with electrically separate conductors which are formed of a plurality of electrodes distributed over the peripheral surface of the probe body.    A plurality of at least six electrodes which can form six bipolar electric fields are formed which in one embodiment are aligned longitudinally on the probe body.  The elec-trodes extend onto the probe body's distal end to provide an omnidirectionally effective electrosurgical device.  A central conductive wash channel is provided for electrical connection to a set of electrodes at the distal end of the probe body while also providing a passage for fluid to enhance the visibility of the target area for subsequent precise electrocoagulation of  the device.   Several embodiments are shown and described.

Abstract: A B S T R A C T O F T H E D I S C L O S U R E The present invention relates to a new technique and device for mass transport operation and physical separation involving selective barriers. According to the new technique, the mass transport through the selective barrier and physical separation are carried out in the same device. The device consists of a mixing-reservoir into which is fitted snugly a mixer-separator, having a channel in the vertical axis of the mixer-separator, the mixer-separator being provided with means for accumulating of gas pocket to decrease the pressure exerted on the barrier. The completely solid-free liquid passing through the selective barrier is removed by pushing in the mixer-separator, said liquid being accumulated in a collecting container. Typical examples of such selective barriers are ; membrane, bed of adsorbent material, paper, plastic, glass and metal filter or any other porous material, hollow fibers etc. The new technique and device can be successfully utilized in any operation involving separation of solids from liquids and particularly useful in immunoassay, sterilization, ultra-filtraction, desalination by reverse osmosis, etc.

Abstract: ABSTRACT OF THE DISCLOSURE          A temporary tension anchor assembly for securing part of a structure to the earth includes at least two comple-mentary shaped parts forming a regular shaped exterior.  One or more ribs are formed on the exterior peripheral surface of each part so that it can be engaged within a settable grout material when it is inserted into a borehole formed in the earth.          A spacer member is positioned between facing surfaces of the parts and holds them in spaced relation along the length of the parts within the borehole.  The spacer member is removable from between the parts when they are anchored in a grout sub-stance so that the parts can then be removed by exerting a pull-ing force on them.  The dimension of the spacer member between the facing surfaces of the parts is at least equal to the dimen-sion of the ribs outwardly from the parts, whereby upon removal the spacer member leaves an open space within the borehole suf-ficient for the part to move inwardly with its rib being fully displaced from the grout substance for removal of the part out of the borehole.

Abstract: 22.                        ABSTRACT      In a material working (e.g.  penetrating,  loading, compacting machine the power and machine weight needed to achieve a given performance can be reduced by making one  (50)  of  two  pivots  (34,50)  at  which  a  working implement such as a bucket 14 is supported an eccentric pivot and driving it by means of a motor  (36).   The circular vibration of the bucket at pivot (50) combined with arcuate vibration which results and is permitted at pivot  (34)  by means of link  (30),  causes the working portion, namely bucket teeth (56), to vibrate on a closed elongate curved path 58.  This improves penetration and loading  performance  of  the  bucket  without  requiring excessive power to generate the vibrations.

Abstract: Abstract In combination with a cap for a filler neck of a fuel tank, a pressure/vacuum valve assembly comprises a pressure-release valve, a vacuum-relief valve, and a pressure-release control member in a vent passageway in the cap.  A yieldable control spring urges the pressure-release valve normally to close and seal the vent passageway and urges the pressure-release control member to form a restricted opening for the flow of fuel vapors.  The pressure-release valve is urged in opposition to the control spring to open the vent passageway in response to a predetermined superatmospheric pressure and allow fuel vapor to flow in the restricted opening.  A relatively small increase in pressure in the restricted opening produces a large force against surfaces of both the pressure-release valve and the pressure-release control member in opposition to the control spring to rapidly increase the flow of fuel vapor through the vent passageway.

Abstract: ABSTRACT OF THE DISCLOSURE A canvas tarpaulin having dimensions sufficient to cover the top of an open truck box has one edge affixed to one longitundinal edge of the truck box top.  The opposite edge of the tarpaulin is affixed to a tube which extends for the lenth of the box.  The rear of the tube contains an extension attached to a universal joint.  A crank handle is also attached to the joint so that the tube can be rolled transversely across the top to roll up the tarpulin thereon. A downward cantilevered lip is attached to the opposite longitudinal edge of the box top.  When the tarp is unrolled, the tube rolls over a free edge of the lip and can be wound in the opposite direction rolling up a small portion of the tarpaulin under the free edge. The crank handle is then moved against the rear of the truck body thus locking the universal joint thereby holding the tarp tightly upon the box top.  The crank handle is then secured against the rear of the box.

Abstract: ABSTRACT OF THE DISCLOSURE         A  voltage  regulating  transformer  utilizing  a microprocessor and a versatile multipurpose set of hardware modules and software modules it is described.  A standard tap changing mechanism is driven in response to an analog control signal  to change  the output voltage of  the  transformer in response to digitally sampled values of voltage and current which  have  been  transformed  from  the  time  domain  to  the frequency domain  through  a software program  using Fourier transform techniques.  The output current is also transformed and digitally processed to determine the power factor and the direction of power flow through the transformer.  By inserting the digital values of the line characteristics to the load, line drop compensation is provided for.   The difference in voltage  across  the   input  and  output  transformers   is transformed to a digital signal and internally processed to provide an indication of  the position of  the  tap changing mechanism without  relying  upon  mechanical  devices.    The various software and hardware modules are designed so as to be readily utilizable in other electrical distribution controls.
