Abstract: ABSTRACT OF THE DISCLOSURE         Method and device for disintegrating concretions, or sclerotic clots within human ducts.  The method and system are particularly adapted to disintegrating stones in the ureter and kidney, as well as the bladder.  The method includes axially abutting the concretion within the human duct while outwardly distending the walls of the duct adjacent the concretion, directing a series of high voltage, low amperage pulses into the ducts and discharging the pulses radially outwardly across the surface of the concretions, while flowing a liquid peripherally of the dis-charging pulses, so as to direct an hydroelectric impact against the concretion.  The outward distending of the walls and the flowing liquid, particularly in narrow human ducts such as the ureter, prevent tissue damage by shock and burning.

Abstract: Abstract A plurality of multi-functioning machines are simultaneously controlled by similar transmitter/ receiver pairs, one of which is associated with a pro-grammable controller and the other of which is associated with a machine.  In the controller terminal, each trans-mitter of one such pair transmits a series of groups of serial command signals while its receiver receives corresponding groups of serial condition-responsive signals from the machine which update the controller.          In the machine terminal, the transmitter of the other pair is connected to the controller receiver and the receiver is connected to the controller transmitter.          Each transmitter derives input from a multiplexing matrix and each receiver outputs its information through a demultiplexer matrix.  Each transmitter/ receiver pair is driven by a free-running clock but the pair associated with the machine is slaved to the controller transmitter.  Provision is made for connecting a series of machine pairs to a single controller pair, and data transfer between transmitter/receiver pairs is blocked upon detection of transmission breakdown.

Abstract: EXTRA CAPACITY STEAM IRON   ABSTRACT           The invention is directed to an extra capacity steam  iron  with  a  soleplate  having  steam ports and heating means and separate forward main, and rear surge, steam generators with conventional means for selective delivery of water to the generators and having a heat regulating thermostat.  The improvement to this structure comprises a walled enclosure on the soleplate defining the surge generator in the rear half of the iron and tortuous passages lead from the enclosure to the sole-plate ports.   A boss is provided upstanding from the soleplate spacedly disposed in the enclosure and a cover-plate defines steam distributing passages from the main generator and, with the enclosure and the passages, sepa-rate distributing passages from the surge generator.  The upstanding boss is in the form of a pyramid with plural slanted striated surfaces sloping toward the soleplate, the striations being in the form of parallel grooves di-rected down the surfaces to spread and direct water into the enclosure.  The water delivery means dumps water sub-stantially centrally of the boss so that the boss forms a heat sink and a water spreader throughout the walled en-closure for efficient and rapid heat transfer to form extra capacity steam.

Abstract: ABSTRACT     The effective transition temperature from martensite to austenite in a dimensionally heat-recoverable memory metal member can be temporarily raised by applying a stress and maintaining the applied stress at a tempera-ture below the raised transition temperature so that the memory metal remains substantially in the martensitic state.  When it is desired to utilise the member the stress is removed at a temperature above the original transition temperature.  The applied stress is advantageously maintained by a disburdenable keeper. In an especially preferred embodiment the keeper comprises an aluminium tube positioned within a band or tube made from a brass memory alloy, the combined article being suitable as a connector for hydraulic pipes and the like.
