Abstract: A heat exchange device for the introduction of thermal energy into and removal of thermal energy from liquid-solid phase change material is described in which the phase change material is maintained in a container, which is slowly rotated about a generally horizontal axis at a substantially constant rotational speed.  Means are provided for automatically nucleating the phase change material as required for cyclic operation.  The invention is of particular utility in the use of incongruently melting hydrates for the storage of thermal energy.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus are disclosed for mechanically locking a movable filter shell of a pressure filter in filtration position adjacent a second fixed filter shell, in order to accommodate and resist higher internal filtering pressures.  In the method, a gasket between the two filter shells is compressed to an extent greater than necessary to achieve a liquid tight seal, in response to movement of the movable shell toward the fixed shell.  Next a locking member is freely inserted between the movable shell and an abutment with clearance being provided in order to facilitate the insertion of the locking member due to the movable shell excessively compressing the gasket.  Upon initiation of the filtration cycle, the movable shell is slightly displaced away from the fixed shell in response to internal filtration pressures, with the locking member preventing further displacement in order to maintain the gasket in water-tight sealing compression.  Upon termination of the filtration cycle, the movable shell is slightly displaced toward the fixed shell, to provide clearance for free withdrawal of the locking member.

Abstract: Abstract of the Disclosure A protective cover for a video disc comprises a jacket and a record retaining tray removably located therein.  A video disc player includes latch arms which engage the tray when an occupied cover is fully inserted into the player.  Such engagement precludes a removal from the player of the record retaining tray during a jacket withdrawal from the fully inserted position, whereby a jacket withdrawal subsequent to an occupied cover arrival at the fully inserted position results in the retention of the enclosed record in the player.  The tray is so constructed that the retained record is caused to rest on a depressable platform upon a conclusion of the jacket withdrawal.  A subsequent lowering of the platform effects a transfer of the retained record from the platform to the player turntable.

Abstract: ABSTRACT OF THE DISCLOSURE A digital data recorder is adapted for receiving a plurality of paral-lel input data members for defining a single input signal. Any of the input data members may change in identity during the presentation of the single input signal, and the recorder gives priority identity to any input data mem-ber which is of the priority identity for any time during the presentation. The recorder produces a serial, digital data output signal comprising a finite se-quence of binary data bits in one-to-one correspondence with the parallel input data members, with the binary state of the bit corresponding to the identity of the input member. The serial, digital output signal is suitable for recording on the single channel of a magnetic tape for fully defining the input signal. The recorder is described in detail as adapted for recording the words taken by a shorthand machine.

Abstract: A method and apparatus for collecting fibrous material, particularly small diameter glass fibers, i.e. within the range of 0.05 to 2.60 microns, from a gaseous medium in an efficient, environmentally sound manner is disclosed herein.  The apparatus includes a collection chamber which partially encloses a rotating drum having a perforated peripheral surface and having a fine mesh collec-tion screen superimposed thereover.  The drum is positioned in such a manner that the screen intercepts a gaseous stream of fibers, e.g. glass microfibers.  A suction force established interiorly of the peripheral surface of the drum draws the gaseous stream through the collection screen in order to thereby continuously collect a layer of fibers upon a portion of the rotating screen.  The layer of fibers is removed from the drum and wound on a mandrel at a point outside the collection chamber.  In a preferred embodiment of the present invention the drum surface is cleaned of any residual fibers.

Abstract: ABSTRACT                  DIRECT HEATER WITH AXIALLY  VARYING POWER DISTRIBUTION      An electric cartridge heater is provided to simulate a reactor fuel element for use in tests of model nuclear reactor systems. The electric heat generating element corresponds in external shape and configuration to the fuel element and electrical current is passed through the tube from end to end.  In order that the heat distribution will simulate that of the actual fuel element, the wall or thickness of the tube is varied from end to end, being thickest at each end and thinnest in the middle.  This is attained by starting with a uniform tube and expanding the central section so that its internal diameter is greatest in the middle and least at each end.  The external surface is then machined to its required uniform diameter whereby the wall thickness varies.  By proper calculation, the desired wall thickness scan be determined to provide the proper power distribution.
