Abstract: ABSTRACT OF THE DISCLOSURE   A variety of objects, including an invalid or a non-ambulatory hospital patient may be moved from one location to another.  The transfer device includes a conveyor belt, a frame for supporting said conveyor belt, a base for holding said frame, driving means for translating said frame relative to said base, and connecting means for connecting or releasing a part of the upper portion of said conveyor belt with said base.  When the connecting means connects a part of the upper portion of said conveyor belt with the base, the conveyor belt is not only carried with the frame, but also is rotated around the frame by driving the frame relative to the base.  On the other hand, when the connecting means releases the belt from the base, the conveyor belt is also carried with the frame but is not rotated around the frame by driving the frame relative to the base.  A patient is moved by placing the device adjacent to his. At first the connecting means is operated to connect a part of the upper portion of the conveyor belt and the base, and then the frame is driven toward the patient.  When the frame together with the conveyor belt contact with the body of the patient, the leading edge of the conveyor bolt which is rotating in an upwardly-oriented direction, gently and uniformly lifts the patient up into the frame.  Then, the connecting means is operated to release the conveyor belt and the base, and the frame is driven reversely.  The patient on the frame is carried with the frame to just above the base.  The transfer device may include the second belt which is placed just below the first conveyor belt and is fixed always to the base. Further the transfer device may form an integral part of an apparatus such as a wheeled stretcher, or it may be used independently.  Upon arrival the patient is off loaded by operating the transfer device adversely.

Abstract: ABSTRACT OF THE DISCLOSURE          Accelerating a large inertia load by means of a synchronous dynamoelectric machine.  During starting, a quadrature axis winding disposed around the stator of a brushless exciter is energized by single phase alternating current.  Alternating current excitation is induced by transformer action within the rotor armature winding of the exciter and is applied to the rotor field winding after being rectified by the rotatable rectifier assembly.  Poly-phase alternating current excitation is applied to the synchronous dynamoelectric machine stator winding to establish a dynamic magnetic field which rotates at a speed proportional to the frequency of the applied excitation.  Interaction of the static agnostic field of the rotor and the rotating stator field produces the mechanical turning force.  The frequency of the synchronously applied stator excitation is increased from substantially zero cycles per second to a higher frequency until the rotor member has accelerated synchronously to the desired speed of rotation.

Abstract: Abstract of the Disclosure A method for the recovery of sulphur compounds, volatile alcohols such as methanol, as well as by-products such as turpentine and the like, which are formed in connection with pulping, from the blow-expansion condensates from the evaporating series of a digestery, from turpentine mother liquors, or from other liquids in a separate treatment unit.          The liquids are treated in a vacuum stripping unit by means of a proportion of secondary steam which is obtained from the last step of a multi-stage evaporating plant. The excess of secondary steam is condensed by means of indirect condensation in a first surface condenser, whose exhaust vapours, together with the vapours leaving the stripping unit and with gases that are to be removed from the evaporating steps,are condansed by means of indirect condensation in a second surface condenser. The condensate from the second surface condenser is used as return flow into the stripping unit, and the gases leaving the condenser are, by means of a vacuum device, passed into the condensate tank of the evaporating plant. The gas fraction obtained from the condensate tank is removed to a separate treatment, as well as the condensate fraction produced therein is either recirculated to the treatment or recovered separate-ly. The purified liquid from the stripping unit is re-circulated to the process.

Abstract: TITLE MEANS FOR RETARDING THE SPREAD OF FIRE FROM A SPACE IN AN               ENVIRONMENT ISOLATING STRUCTURE            INVENTOR                      Tibor Z. Harmathy ABSTRACT OF THE DISCLOSURE           A means for retarding the spread of fire from a space in an environment isolating structure, e.g. a building or a ship, comprises a duct system for conveying gases away from a fire in the space, an access gate operable to connect the space to the duct system, a fan for aiding the movement of the gases along the duct, and a means for opening the gate and starting the fan when a fire occurs in the space.  The cross-sectional area of the duct system is related by formulae to the area of air intake to the space and the pressure head to be de-veloped by the fan in order to i) drain away smoke and flames from the space containing the fire, ii) produce a depression in the space and thereby prevent the flames and smoke from entering any neighboring spaces, and iii) draw sufficient air into the space to ensure relatively low fire temperature and a relatively short fire duration.  Preferably a release. gate isolates the exit end of the duct system from the out-side atmosphere until a fire occurs in the space.

Abstract: XEROGRAPHIC COPIER               ABSTRACT OF THE DISCLOSURE            A xerographic copier including a novel photo-conductive belt and drive structure is disclosed.  The thin metal belt is provided with at least one transverse break or gap and is preferably formed of two belt segments.  In use, the break or gap between segments are held in end-to-end relationship to tow bars which captivate the edges of the segments, hold them in position and provide mechanical bias therebetween.          The photoconductive belt is driven in a unique manner by means of the tow bars which are drawn about a non-circular path by an inelastic but flexible guide means such as chains and sprockets.  The belt passes over drums which support the belt and define its path but do not drive it.  The drums include a low friction surface and provision (a soft layer) for accommodating small foreign objects that may pass between the belt and the drums without hurting the belt.  The tow bars project only on the inner side of the belt and pro-vision is made for accommodating them on the drums so as to not excessively bend the photoconductor bearing surface of the belt.  This provision is at least one channel in each drum which are driven in synchronism with the tow bars and so sized and spaced as to have the channels receive the tow bars as they travel about the path.

Abstract: ABSTRACT OF THE DISCLOSURE    A new hospital bed is provided herein having a lower frame or dolly, an upper frame or mattress support, and a middle frame comprising two longitudinal beams, a head end, a foot end and a central section.  The head end is formed by a single "U" shaped tube which joins the beams, holds a head board, supports the side rails, and provides recesses for IV tube support rods; the foot end is formed by a single channel having similar and additional functions as the head end; and the central section of the middle frame includes a pair of wing-like plates which form a part of and provide the principal support for the upper frame.  The total number of components of the bed is substantially reduced by the design of these components to serve multiple functions, which conserves material, reduces expense, and allows fro easier repair and adjustment.  Drive mechanisms cause the middle frame to rise or descend, the head end and foot end to tilt upward and downward, and the upper frame to bend, thereby tilting the head, thigh and leg sections independently.
