Abstract: ABSTRACT OF THE DISCLOSURE   Propulsion means for a marine vessel intended for operation under severe ice conditions comprises a multi-bladed propeller, which may be of fixed or controllable pitch, a stationary duct, which may take the form of a nozzle, within which the said propeller runs and is protected peripherally against ice damage, and, at the forward and aft ends of the duct, water-guide members in the form of vanes and/or blades which are more massive than is required by their water-guiding functions and which restrict the size of ice masses that can encounter the propeller by entering the duct at the said ends.  The duct may embrace the propeller peripherally around the full 360°.  The water-guide members may be secured at their outer ends to the duct and at their inner ends to ring members co-axial with the propeller.  The upper quadrant of the duct may be secured to the hull of the vessel and the lowest portion of the duct to a skeg extend-ing beneath the duct.

Abstract: ABSTRACT OF THE DISCLOSURE A process is provided herein for the isolation of .beta. -sitosterol in yields over 90% as a hydrate from a sterol-mixture separated from the neutral fraction of raw soap by heating the sterol mixture together with only one solvent mixture.  The invention involves using, as the solvent mixture, an aqueous solution of a solvent that forms hydrogen bonds, e.g. an acetone and water mixture, or an isopropanol and water mixture.  When the mixture is cooled to 15°C or below, a product rich in .beta. -sitosterol is crystallized as a hydrate.  This product contains, in addition to .beta. -sitosterol, a maxi-mum of 4% ? -sitosterol, 7% campesterol and 0.5% other impurities.  The process is easy to carry out since it uses inexpensive solvents.  The final product obtained is of sufficient purity to be useful as such for pharma-ceutical purposes.

Abstract: ABSTRACT An improved stethoscope having means for measuring the frequency of a series of pulses such as pulses of a human heart, is disclosed, in the use of which such pulses are sensed simultaneously with detection of a series of timed detectable reference impulses produced by a reference impulse producer (14) having means (16) for adjusting the frequency of the reference impulses produced thereby and also having readout means (17, 18) indicating the frequency of the reference impulses, wherefore upon adjustment of the frequency of the reference impulses as necessary to match that of said pulses, the frequency of said pulses is indicated on the readout means (17,18). The improved stethoscope is provided with means (15 or 15') for manually activating and deactivating the impulse producer, such that successive actuation thereof switches the stethoscope from diagnostic examination mode to pulse measurement mode and back again to diagnostic examination mode.

Abstract: DRAFT CONTROL SYSTEM Abstract of the Invention A  draft  control  system for furnaces  comprises an auxiliary channel in communication both with ambient air and the flue of the furnace, a main draft control means for regulating the entrance of ambient, auxiliary draft air  into  the flue,  and auxiliary draft  control means mounted  in  the  auxiliary  channel  for  dampening  the effect of extreme changes in external conditions on the main  draft  control  means.   Thus,  uniform  draft  and efficient combustion is maintained in the furnace under a wide variety of conditions.   The main draft control means  comprises  counter-balanced  draft  control  plates which are initially set in an open position so that they can  either  open  or  close  in  order  to  efficiently regulate the  draft in the flue.   The  auxiliary draft control means comprises, in one embodiment, an isolation damper  plate  rotationally  mounted  in  the  auxiliary channel,  or,  in a second embodiment,  a set of louvred panels.   The position  of  the  auxiliary  draft  control means is automatically regulated by a pneumatic control device   responsive   to   the   efficiency   of   furnace combustion.

This domed or arched surface is formed, for instance, by the jacket or outer surface of a dewatering cylinder arranged within the wire loop of the longitudinal wire.  The longitudinal wire is provided with a headbox and extends forwardly and after the dewatering apparatus essentially in a wire plane,  above which upwardly rises the domed surface.  Both of the wires are guided out of the wire plane over a dewatering shoe arranged within the wire loop of the additional wire towards the domed surface  and  from such --if desired over  a deflection coil arranged beneath the wire plane-- again towards the wire plane, where both wires separate from one another.   Due to this arrangement  there is realized a guiding of both wires which improves the dewatering action and is extensively independent of the elevational position of  the  wire plane,  and  at  the  same  time  affords a constructional simplification of the papermaking machine.

Abstract: TIP CONFIGURATION FOR A LIGATING CLIP APPLIER            Abstract A multiple clip applier including a handle and a cartridge which holds a large number of ligating clips and which snaps into a cartridge-receiving channel on the handle. The handle operates like an elongated scissors with scissors handles at one end and jaws at the other to which clips may be delivered in rapid succession.  Opening and closing the scissors handles operates the mechanism of the handle to open and close the jaws and to provide a long stroke motion for delivering clips from the end of the cartridge to the nose section.  Clips may be indexed through the cartridge by reciprocating parts of the cartridge with respect to one another with a short stroke cocking motion captured from the long stroke delivery motion from a cooperating slot and pin mechanism.  These two motions are accomplished within the envelope of motion of the normal opening and closing of the scissors handles to operate the jaws of the applier and to feed and index clips from the cartridge to the nose.  The mechanism of the present invention permits the overall shape of the handle to be small, compact and readily adaptable for use even deep in an incision site.

Abstract: SELECTIVE SHIFTING AC PLASMA PANEL An AC plasma panel display is described with selective row and column shifting capability. Alternate ones of the column conductors are common between a staging area and an exhibiting area while the other column conductors in the staging area are terminated at the boundary between the two areas. The row shifting is accomplished in the staging area to enter display data on the panel. Column shifting is used between the two areas to transport display data onto the exhibiting area from the staging area. The termination of the other column conductors short of the exhibiting area allows lateral shifting of the data through the staging area without similar shifting of the data in the exhibiting area.
