Abstract: A method to draw the thermal energy from essentially limitless heat sources, such as the ocean or the atmosphere and limited heat sources such as the combustion of fossil fuels, is provided for the production of mechanical work. The fluid from the heat sources gives heat to the working medium of the prime mover of the power plant through a first heat exchanger. The effluent cooled fluid from the first heat exchanger is used for removing the exhaust heat from the prime mover through a second heat exchanger either directly or indirectly through a heat pump and can also be used for the conversion of saline water into fresh water.

Abstract: A belt buckle comprising a body adapted to be connected to a belt for wearing on a user and having a structure which simulates a known object having a movable component, for example an automobile, bell, or animal such as a bird. An element is movably connected to the body and located so as to be exposed to view when the buckle is worn on the user, and the element has a structure which simulates the movable component of the object, for example the automobile hood, bell striker or bird beak. An operator member is movably carried by the body and responsive to manual operation, and a motion transmission mechanism carried by the body and operatively connected to the element and to the operator member converts movement of the operator member in response to manual operation into movement of the element relative to the body. As a result, activity of the known object is simulated.

Abstract: A window insulating system including horizontally and vertically arranged channel members positioned in a window wall opening and spaced inwardly of the window surface. Insulating panels are positioned in the channels and can either be opaque fiberglass panels or translucent or transparent panels of glass or plastic. Horizontal channels are secured adjacent the upper edge of the window wall opening and can be secured adjacent the lower edge of the window wall opening or can be above that surface. The vertical channels are frictionally attached to the panel member and the panels plus vertical channels are slipped into the horizontal channels and are thus easily removable for access to the window for maintenance or cleaning purposes. The outer edges of the outermost vertical channels adjacent the vertical window wall opening edges are formed from a resilient material and include an integral, outwardly extending sealing strip which is in sealing engagement with the adjacent window opening edge.

Abstract: Shaft seals of the lip type with a sealing member bonded to an apertured insert have a tendency to form blisters in the sealing member near the bond. In order to avoid this, and provide a seal suitable for use in hygienic environments, the sealing member is mechanically engaged with the insert, for example, by being in the general form of a grommet with a central boss filling in the aperture and carrying the sealing lips, and having a wide radial flange forming a cleanable face exposed to the process fluid and a narrow deformable flange adapted to pass through the aperture of the insert and to expand into mechanical engagement therewith.

Abstract: Apparatus for sensing the electrical conductivity of fluid which can be used to detonate an electro explosive device for operating a release mechanism for uncoupling a parachute canopy from its load upon landing in water. An operating network connected to an ignition capacitor and to a conductivity sensing circuit and connected in controlling relation to a semiconductor switch has a voltage independent portion which controls the time at which the semiconductor switch is closed to define a discharge path to detonate the electro explosive device independent of the rate of voltage rise on the ignition capacitor. The operating network also has a voltage dependent portion which when a voltage of predetermined magnitude is developed on the conductivity sensing circuit in response to fluid not having the predetermined condition of conductivity, the voltage dependent portion closes the semiconductor switch to define the discharge path when the energy level is insufficient to detonate the electro explosive device.

Abstract: In plate heat exchangers the dismantling of the pack of plates is a lengthy job which normally has to be carried out in situ. A plate heat exchanger has a frame including a head (3), a supporting pillar (7) and a movable follower (4) mounted on a top rail (2) extending between the head (3) and pillar (7) which also carries the plate pack (1). In accordance with the invention, the top rail (2) is readily releasable therefrom by bolts (13) whereby the whole plate pack (1) may be lifted clear of the frame. The follower (4) may be temporarily accommodated on the supporting pillar (7) by clamping means (10) and the roller (5) removed. The top rail may be provided with means for attachment of lifting shackles (11).

The mask assembly (10) is further provided with pressure compensating means (38) capable of blocking the exhalation valve (26) of the gas mask.

Abstract: A seal for sealing the clearance between a shaft and two close annular surfaces through which the shaft passes is in the form of a ring-like body having a central portion and two lip portions extending therefrom and hingedly movable thereto and which when the seal is mounted upon the shaft is placed in a deformed condition and in sealing engagement around the shaft. The body is of such cross-sectional shape that when stretched from an undeformed condition to a deformed condition about the shaft, each lip portion moves from a first angular position to a second angular position relative to the midplane of the body. When the seal is operatively placed upon a shaft so that each lip portion is placed in contact with a corresponding annular surface through which the shaft passes and each lip portion is thereby prevented from moving completely to its second angular position, the lip portions are axially biased into sealing engagement with the annular surfaces.

Abstract: Apparatus for applying elastic rail fasteners to a rail seat in which the fasteners are applied in a direction at right angles to the rail. A carriage supports a pivoted frame which can be rotated to align with a rail tie. Each end of the frame carries a pair of dependent arms and each pair is moved hydraulically. Abutment faces on the ends of the dependent arms contact the rail fasteners and the simultaneous contraction of each pair results in the fitting of four rail fasteners in one application. Rail tie position sensors are provided adjacent the abutment faces for correctly aligning the frame with the rail tie.

Abstract: A high-hat cymbal stand of the type including a support pipe, a foldable leg assembly having a plurality of legs and a coupler which is mounted for movement along the support pipe and to which each of the legs are attached, a set screw for releasably locking the coupler to the pipe, and a pedal assembly having a weight-supporting member which shares the weight of the stand with the legs when the stand is set up for play utilizes a spring operatively connected between the support pipe and the leg assembly which when the stand is placed upright upon a floor or similar supporting surface holds the weight-supporting member of the pedal assembly in spaced relationship to the floor. An associated method of setting up the stand distributes the weight of the stand between the pedal assembly and the legs so that the stand does not wobble or creep across the floor during play.

Abstract: A trench is dug under the pipe. A collapsible means formed by a supple and deformable envelope is conveyed into the trench as it is dug in a state folded or coiled upon itself. The envelope is filled with water by a pump assembly and unfolded in a diverging cone, and progressively substituted for materials extracted as the trench is dug. The pipe is then lowered into and positioned in the trench by the escape of water out of the envelope through orifices or valves.
