Abstract: Beds are disposed into multistoried columns parallel to a longitudinal axis of an array and displaceable between an interior of a frame which shelters and supports and guides the beds through openings, and an aisle for occupying and vacating the beds. The bed comprises a front wall with a sealing means for closing off the opening, and side and end walls with sealing means and a head cowl for closing off private interiors at rests. The beds in the oblique-angled array are displaceable longitudinally at an acute angle to the axis and have front bins for closing off the openings. The beds in the axial straightforward array are displaceable transversally to their axes at below of private bins in the frame and on foldable trap-shields.

Abstract: Geothermal energy is recovered from magma via a vent of volcano by a longitudinally displaceable, closed system of one tube for injecting working condensed water and the other production tube for return of heated water, and a number of heating tube members connected to front portions of the tubes. The water may be assisted in its return by a pump. The tubes are capable to be advanced relative to a stationary shelter building by a drive means disposed securely at the vent. The front portions are articulated and/or flexible, and provided with a chassis. The tubes may be in co-axial relation and the outer injection tube is used as the heat economizer and insulator tube, and provided with sank and movable scraper members to remove a scale. A heat exchange means is operable to recover thermal energy from the water.

Abstract: Unit plates are supported by unit frames connected consecutively together for turning about axes being remote from and crossing a longitudinal axis of the frames with the ability to alternately be shifted about the turning axes by rams coupled between the plates and frames and expanded while the frames are shifted continuously. The front frame supports alternately a face-and-end pumping mill, facing disk or wedge or endless chain cutter. A ski tenon supported on the front end of the front frame that is able to be engaged with a ski-trak means of adjacent from behind the same unit frames for relative turning about the axes and disengaged in the trench.

Abstract: A floatable surface vessel comprises a vessel hull having a circular sector-shaped cross-section and a ballast filling with a controllable position of a centre of mass disposed remote from the circular centre and adapted to come into resonance with rocking action of water waves being induced a rocking motion of the hull about the circular centre and a frame being supported on the hull for rotation about the circular centre to be isolated from the rocking.

Abstract: A tangential turbine is adapted for receiving kinetic energy from a flowing fluid and comprises a supporting shroud, a rotating runner having a hub and a plurality of radial blades spaced apart on the hub, and a means for controlling the receiving. In first embodiment the controlling means comprises a plurality of springs each connected with its ends turningly about a connecting axis being between and within the hub and the blade and between limit stops to the hub and fixedly to the blade turnable about the axis to a non-working tangential position. In second embodiment the controlling means comprises the shroud shaped into a caisson and provided with turnable aprons and capable of accommodating the runner in the air and controlling the insertion of the blades into the flow below the shroud.

Abstract: A number of front working, trench filling face-compressing, inclinedly disposed sliders are arranged alternately with cutter bits on an endless chain of a trench-forming endless chain cutter on a transporting chassis, and driven with the chain by a drive means so that backward oriented, inclined facet portions of the sliders compress a filling in the trench toward and on a front working face of the wall being formed. An elongate, filling face-compressing shield is adapted to be extended down into the trench and supported with its underground portion on the underground portion of a guide post of the cutter or on the trench bottom for forward and backward oscillation by a drive means to compress the filling face adjacent to the shield. The compacted filling is in these ways being formed by horizontal pressure.

Abstract: A number of slot filling-compressing members are inserted from a framework into and across a slot-shaped excavation at ahead of a frontal face of a continuous, compacted slot filling being formed along the slot, and moved with a drive means connected to the members for intermittently forcing portions of the members against the filling to compress the filling adjacent to the members longitudinally against the face. The compacted filling is in this way formed by longitudinal pressure. The members can be mounted for forward or reciprocating movement in directions along and across the face.

Abstract: A tandem axial turbine that comprises a front confusor, a funnel-shaped runner having inner blades and capable of accelerating and directing an oncoming flow toward a co-axial rear runner which rotates in an opposite direction. A tangential turbine has a hub, blades capable of rotating in relation to the hub between positions across and along the flow, and propulsion springs for controlling the movement of the blades in relation to the hub and the transfer of the energy. A second tangential turbine comprises a runner having a hub and blades and a shroud capturing the runner from above and around and permitting the blades to dip into water flowing immediately below the hub and an opening of the shroud. A surface vessel comprises a stabilized frame rotatably affixed on a vessel hull about a center of wave induced rocking motions of the vessel and therefore isolated from a rocking motion of the vessel.

Abstract: An excavating member of a constructing means inserts downwardly from a chassis into the ground with an activating means of the chassis and a drive means of the constructing means located within an excavated section and connected to the excavating member and a supporting frame of the constructing means for forcing portions of the member laterally against the facial wall of the section being advanced relative to the frame in a direction opposite of an advancing direction diverged from the axis of the section to excavate the ground adjacent to the member ahead of the frame toward the advancing direction. The section is in this way formed in the diverged advancing direction. The member can be mounted for lateral movement about an axis perpendicular to the advancing direction and within the central surface of the constructing means. A set of “n” side wall-supporting members can be connected to the frame for relative movement about an axis of turning advancement of the section.
