Abstract: Abstract SPINDLE LOCK-UP DEVICE         A spindle lock-up device (11) is provided for releasably locking a rotary spindle (1) having a tool holder (9) to a non-rotatable support (2), such as the ram of a vertical boring machine, so that the spindle tool holder (9) also may be used as a fixed tool holder for the ram (2).  The device (11) has a first spiroid gear member (14) -fixed to the ram (2), a second spiroid gear member (17) fixed to the spindle (1), and a third spiroid gear member (19) surrounding the spindle (1) and mounted for axial movement from a retracted to an extended position, the third gear member (19) simultaneously engaging the first (14) and second (11) gear members when in the extended position to lock the spindle (1) against rotation relative to the ram (2). The third gear member (19) is moved to the extended position by a piston (25). (FIGURE 1) 10JOS16851b/0961A/G-130

Abstract: PENILE IMPLANT                    Abstract of the Disclosure A penile prosthesis (20, 200) comprising at least one cylinder (22) for implantation in the penis and including a front tip section (24), an intermediate section (28), and a rear tail section (26).  The intermediate section (28) includes at least one tubular member (46, 204) which is inflatable, and arranged to assume an elongated rigid and hard state from a flexible, flaccid state upon the application of an operating liquid (42) under pressure thereto.  An expandable bellows (36) having an actuating fluid (38) therein is located in the tip section.  The actuating fluid (38) expands from a first state to a second higher volume state upon the application of energy (e.g., heat) thereto.  The expansion action causes an operating liquid (42) located in at least one reservoir (40, 222) to be provided under pressure to the inflatable tubular member (46, 204) in the intermediate section to cause it to become erect.  Upon the dissipation of said energy from the actuating fluid the bellows (36) contracts, whereupon the intermediate section (28) of the cylinder becomes flaccid again.

Abstract: ABSTRACT OF THE DISCLOSURE    A bobbin assembly for a soldering/desoldering device may be readily produced by utilization of a heater assembly comprising an electrically insulating tape-having an etched foil heater bonded to one side thereof.  The bobbin assembly is formed by wrapping the heater assembly about a cylindrical bobbin so as to form a first insulating layer in contact with the bobbin, a layer comprising the heater in contact with the first layer and a second insu-lating layer in contact with the heater.  A wire is then wound about the entire assembly, in a helical manner, to hold all elements in place.  Additionally, a dissimilar metal lead may be spot welded to the bobbin to form a thermocouple junction used for sensing the bobbin assembly temperature.

Abstract: HEATING STOVE WITH PLATE HEAT EXCHANGER AND THE METHOD OF MANUFATURE THEREOF          ABSTRACT  As per Examiner This  invention  relates  to  a  heating  stove  equipped  with  a removable plate heat exchanger  which  serves  as  flue  gas  heat extractor,  wood  tar condenser and combustor.  The Heat Exchanger also provides means of channeling away flue gas from the "up-flow" or "down-flow" combustion zone. A novel and inexpensive method for the manufacture of the plate type heat exchanger is given.           BACKGROUND TO THE INVENTION          Heating stove such as used in homes have been used  for  centuries but  they  never amounted to more than an open fire place used for emergency or a metal box  containing a hearth, a chargjng door  and an exhaust leading to a chimney.          The  development  of  the  slow  combustion  type  stoves has been plagued with the problem of increased wood tar  deposits  in  the flue  ducts.   Such  deposits eventually catch fire and have beeen known to consume entire homes and the occupants.  One solution  to eliminate  the  chimney  fire  hazards has been to equip the stove with a catalytic converter which is meant to trap  the  wood  tars and  promote  more complete combustion thereof.  Excesive costs of such catlytists  and  its  containment  appart  from  its  dubious performance have not favoured wide acceptance of such devices.          Presently  the  state  of the art in the stove heaters has been to add an air jacket around the stove to enhance  the  efficiency  of heat  recovery.   However,  because  of  space  and  heat transfer limitations , stoves equipped  with  air  jackets  are  unable  to extract  a large portion of recoverable heat which is then lost to the atmosphere.          When analylizing the performance of a heating stove with  the  aid of  heat transfer theory one must realize that a stove with an air jacket is limited in its ability to recover a  higher  portion  of the heat generated by the combustion process.  The limiting factor is the overall heat transfer coefficient which  is  controlled  by the  velocity  of  air  in  the  jacket.   Also it is difficult to increase the heat transfer area  by  adding  more  jacket  surface because of space restrictions.          SUMMARY OF THE INVENTION          The  object of this invention is therefore to provide a hearth for the  combustable  material  and  a  method  of   controlling   the combustion process so as to ensure full combustion of volatile and

Abstract: PIEZOELECTRIC PRESSURE SENSING APPARATUS FOR INTEGRATED CIRCUIT TESTING STATIONS          ABSTRACT OF THE DISCLOSURE        A pressure sensing apparatus for use in an integrated circuit testing station is disclosed.  The testing station includes a probe, a support structure, and lift means for moving an integrated circuit upward toward the probe.  The invention specifically consists of a pressure pad secured to the support structure directly above the probe.  The pad includes a resilient body portion having a rigid tip.  Embedded within the pad is a piezoelectric element having electrical contact leads attached thereto.  When the testing station is used, an integrated circuit is moved upward by the lift means toward the probe.  As the circuit contacts the probe, it moves the probe upward.  As the probe moves upward, it pushes on the pad, causing internal pressures to be generated therein.  Such pressures are transmitted to the piezoelectric element which generates electrical impulses proportional to the pressures exerted on the pad.
