Abstract: HYDRAULICALLY ACTUATED TWO-SPEED TRANSMISSION         FOR A MARINE PROPULSION DEVICE                  ABSTRACT OF THE DISCLOSURE          Disclosed herein is a marine propulsion device including an input shaft drivingly connected to a power source, a lower unit having a rotatably mounted drive shaft extending in coaxial relation to the input shaft, a rotatably mounted propeller shaft carrying a propeller and drivingly connected to the propeller shaft, and a two-speed transmission drivingly connecting the input shaft to the drive shaft.  The transmission includes a third shaft rotatably mounted in parallel relation to the input shaft and the drive shaft, a first pair of meshing gears including a first drive gear mounted on the input shaft and a first driven gear mounted on the third shaft, a second pair of meshing gears including a second drive gear mounted on the third shaft and a second driven gear mounted on the drive shaft, and a one-way overrunning clutch drivingly connecting one of the shafts to a gear mounted on the shaft when the rotational speed of the input shaft is less than a predetermined value.  The transmission also includes a fluid pressure actuated selectively actuatable clutch for drivingly connecting the input shaft and the drive shaft when the rotational speed of the input shaft is greater than a first value.  The transmission includes a housing and a pair of the meshing gears are disposed in the housing to form a fluid pump for providing fluid to the fluid pressure actuated clutch, the fluid pump developing fluid pressure which increases as the rotational speed of the gears increases.

Abstract: Durant l'hiver, les automobilistes ajoutent sur le sol de leur voiture un tapis de protection dont le rôle est d'empêcher l'eau et le calcium d'endommager le revêtement au sol. Jusqu'à présent, l'extré mite du pantalon du conducteur était inévitablement en contact direct avec l'eau sale, la'neige, le calcium et la bone a l'état stagnant, sur ce tapis additionnel. Dans la présente invention, le pantalon n'est plus en contact avec ces éléments puisqu'il est maintenu par des arêtes triangulaires proéminentes situées au fond d'une cuve dont La profondeur et le dessin permettent la rétention desdits éléments. Les côtés latéraux du tapis sont aussi pourvus de semblables arêtes.

Abstract: TITLE            EXPANDABLE LINK TELEPHONE INTERCOM SYSTEM       ABSTRACT OF THE DISCLOSURE         A multi-link intercom system having a large number of stations selectively connected to one of eight links by respective station controllers.  When a calling station goes off-hook, its station controller connects the station to the first available link during the one of four link access peri-ods corresponding to that link.  The calling station then applies appropriate signals to the link identifying the called station.  These signals are decoded by a link controller for the link which generates called station address signals during its corresponding link access period.  All of the link con-trollers generate called station address signals on the same bus, but the signals are time multiplexed to occur during a portion of each link access period corresponding to each link.          The station controller for the called station recognizes its address and connects its station to the link corresponding to the portion of the link access period in which the station address was received.  Two-way communication between the call-ing and called station is then effected.  Each of the station controllers utilizes a pair of self-contained controller cir-cuits which are inherently adapted to operate with four link access periods and selectively connect its station to one of four audio links.  The system includes circuitry for allowing two of the four-cycle, four-link controller circuits to opera-te in parallel utilizing relatively few additional signal lines as compared to a four-link system.

Abstract: SEMICONTINUOUS PROCESS FOR THE                 MANUFACTURE OF PURE SILICON                   ABSTRACT OF THE DISCLOSURE           Pure silicon is obtained in a cyclic process by reducing quartz sand with aluminum; the finely divided quartz is dissolved in an aluminum sulphide slag and is reduced by molten aluminum.  The molten aluminum also serves as a solvent for the elemental silicon which crystallizes out and precipitates as the temperature falls.  Aluminum oxide formed during the reduction is extracted from the slag and passed on for melt electrolysis in order to recover the aluminum.

Abstract: APPLICATION OF: JAMES C. SWAIN, JAN B YATES & DAVID L. THOMAS FOR:  EXPANDING HOLLOW TUBE ROCK STABILIZER     ABSTRACT OF THE DISCLOSURE        A hollow, elongated tube is inserted without substantial interference into a bore hole in a rock formation having a diameter at least substantially as large as the largest cross sectional dimension of the tube.  After insertion, a mandrel or other expansion means is forced through the tube to expand the latter into frictional engagement with the bore hole wall, thereby reinforcing the rock strata surrounding the tube. In a first embodiment the tube is folded along one or more axial lines to a non-circular configuration, the mandel serving to at least partially unfold the tube.  In a second form , the tube is of circular cross section and remains so as it is stretched by the mandrel into contact with the bore hole wall.

Abstract: ABSTRACT      An apparatus for assembling cooling tubes and fin elements in the manufacture of heat exchangers, particularly radiators for motor vehicles, comprises stations (17), (18) for feeding the tubes (15) and the fin elements (16) to grooves (14) in a rotatable drum (11). A tube and a fin element are positioned together in each groove (14), and are then ejected together at an ejecting station by an expelling device (21). An advancing means (27, 28) advances the tube and the fin element along a transportation path. The tubes and the fin elements are soldered to from units during their passage along the transportation path through a soldering station (36). In a preferred embodiment the feeding station (18) for the fin elements is provided with a separate groove (49) into which the fin elements are fed, before the transfer to the grooved drum.

A double-envelope hull with longitudinal girders defining air flow air spaces for the airship allows for ambient air flow around the inner envelope or for hot air from the engine to change the helium lift within the airship, or melt snow or sleet on the hull.  The airship is also designed to allow speed control for landing, and steering through control of the air flow within the ship, with a bow thruster nose control system and with the main air thrust being provided by a venturi-type shrouded, stern propeller unit with deflector vanes for supplemental steering.

Abstract: "ADJUSTABLE BOWL SCRAPER"          ABSTRACT OF THE DISCLOSURE           Conventional bowl scrapers can be adjusted for height about the transverse axis, but not about a longi-tudinal axis.  This limits the use thereof in side hill locations such as the forming of relatively wide drainage ditches and the like which often require shaping between the wheels of the bowl scraper at an angle different to the attitude thereof.  The present device has the rear wheel axle shafts mounted in vertically situated slider blocks secured to the frame with heavy-duty piston and cy-linder assemblies extending vertically from the axle upon each side of the wheel and between the frame so that each wheel can be controlled individually thus raising and lower-ing each side of the frame individually and thereby con-trolling the tilt of the bucket around a longitudinal axis as well as the conventional control of the bucket position around a transverse axis.  This gives complete flexibility of attitude of the bucket lip.
