Title: Tube sheet accommodating  differential expansion
Inventor: BOLLINGER WAYNE A
IPC: B01D63/02
Filed: 1980-10-17
Granted: 1982-07-27
Abstract: 07-52-0428 APPARATUS ABSTRACT OF THE DISCLOSURE In apparatus containing a bundle of tubes such as permeators, a tubular spacer substantially surrounds a tube sheet in which tubes are embedded for at least a portion of the lateral surface of the tube sheet, The tubular spacer serves to position the tube sheet within the apparatus. The tube sheet has at least one rise region intermediate a face and an expanded zone having larger cross-sectional dimensions than the corresponding dimensions of the face, and the rise region is adapted to abut the tubular spacer. The tube sheet can have sufficient length along the orientation of the tubes in order to ensure a fluid tight relationship between tubes and the tube sheet, and the amount of material to form the tube sheet can be reduced, thereby minimizing the : effect of differential expansions.

Abstract: ION-IMPLANTED BUBBLE MEMORY WITH REPLICATE PORT           Abstract of the Disclosure A bubble memory device made using ion implantation techniques and incorporating relicate ports, such ports not having previously been attainable in such devices.  The device includes a memory loop having first and second legs.  A replicate conductor overlies both legs and is in alignment with a first location on each of said legs at which an attractive pole for bubbles is simultaneously periodically generated by the rotating field used with such devices.  During an interval when such attractive poles are present, a current pulse is applied to the replicate conductor to generate a stable field which is effective to elongate a bubble disposed on one of the legs and to stretch it between the two first locations of the memory loop legs.  The elongated bubble is thereafter split by a bubble collapsing field generated by the rotating field.

Abstract: ABSTRACT    A motor-tachometer rotates a drive shaft rotatably supported on an upper support member that is fixedly secured to a lower support member. The drive shaft in turn rotates a compliant rotary member of larger diameter fixedly secured to a driven shaft for rotation therewith. This compliant rotary member is provided with a circular central portion and an annular outer portion coupled together by three springs symmetrically disposed around the periphery of the central portion, and is loaded against the drive shaft so that the annular outer portion is eccentrically offset relative to the circular central portion in a radial direction opposite the drive shaft.  The driven shaft is rotatably supported by the lower support member in engagement with a drive bar for moving a stage on which the upper and lower support members are mounted along the drive bar.

Abstract: ROLLER-IDLER ASSEMBLY FOR CRAWLER UNDERCARRIAGE               Abstract of the Disclosure This invention is an assembly for bogie mounting a roller to an idler on a crawler track undercarriage such that the benefits of load transfer and shock absorbance are provided for a single roller-idler combination on a crawler track-type vehicle.  A crawler track undercarriage has a track frame to which is pivotally mounted a support link and pivotally mounted thereto a bogie link.  Rotatably mounted on said bogie link are an idler and a roller. Variations in ground level cause the bogie link to rotate such that resilient pads are compressed thereby absorbing shock and so that the less heavily loaded of the roller and the idler has its loading increased. This invention also mitigates the transient loading caused by the crawler track undercarriage being backed into obstacles.

Abstract: ABSTRACT OF THE DISCLOSURE         A goods dispensing device including an annular dispensing port formed in a container, an annular shelf located in a position for receiving the goods released through the annular dispensing port, a table rotatably supported in a position for receiving the goods flowing downwardly from the shelf, a ring located along the shelf for rotation independently of the table, a rotary drive unit connected to the table through motive force transmitting mechanism, a rotary drive unit connected to the ring through motive force transmitting mechanism, scrapers fixedly supported on the ring and projecting above the shelf, a guide scraper fixedly supported and projecting above the table, and a goods conveyor arranged below the guide scraper for conveying the goods dispensed from the container through the annular dispensing port.  There is a relative difference between the rotary movements of the scrapers rotating with the ring as a unit and the table.  The scrapers are operative during the rotary movement of the ring to sweep the goods from the shelf onto the table, so that the goods can be deposited in uniform and continuous loading condition on the table that has a relative difference in movement with respect to the scrapers.  The goods deposited on the table are released from the table by the guide scraper during rotation of the table, to be loaded on the conveyor in uniform and continuous condition.

Abstract: A B S T R A C T         Disclosed is a pulsating spray head for attachment to a source of fluid under pressure, e.g. water.  The head is of simple construction and provides for effective pulsations.  The head comprises a housing in which is mounted a body portion which is closed off by a primary plate having a plurality of rows of radially extending perforations.        A pulse disc is retained within the body portion and has a conical face resting on the primary plate.  Fluid flow through the body portion causes the disc to roll around on the primary plate and sequentially block the rows of perforations in the primary plate whereby pressure fluctuations are caused in fluid exiting the primary plate.  In a preferred embodiment, an orifice plate is secured in spaced relation to the primary plate to form at least one pressure chamber therebetween.  There is always a base pressure within each pressure chamber and rotation of the disc causes pressure fluctuations to be superimposed on this base pressure to cause pressure variations in the fluid exiting the orifice plate.

Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus are disclosed for producing material having on one side a multiplicity of upstanding hook-like engaging elements suitable for repeated face-to-face engagement and disengagement with a material having a multiplicity of upstanding pile loop-like mating engaging elements. The material has a base knitted fabric and a plurality of upstanding monofilamentary members interknitted into the base fabric, with a hook-like engaging element positioned at the upper end of each upstanding member. The material is produced by knitting a base fabric of multi-filamentary yarn material and simultaneously knitting about lancets a series of monofilamentary pile loops which are then contacted by a heated member. The heated member melts the crest portions of the loops and relative motion between the loops and the heated member results in the formation of the hook-like elements at the upper end of each monofilamentary members, with each such element having a configuration in which at least one end portion is generally arcuate and the opposite end portion is generally tapered.

Abstract: A b s t r a c t A method and an apparatus for igniting and burning combus-tible waste oils of high residue contents in a furnace in-cluding at its base an upwardly open combustion (21) and, above said combustion dish, an  optionally divided -combustion chamber (30), and further including means (2, 7, 8) operative to supply the waste oil in metered fashion to said combustion dish (21). Prior to the igni-tion of the waste oil the empty combustion dish (21) is heated to a temperature above the ignition and evaporation temperature of the waste oil by means of an auxiliary heat source (23, 28) adapted to be turned off. The waste oil is subsequently fed onto the heated combustion dish (21) in metered quantities and ignited thereon.            The fuel residues (bituminous slag) remaining in said combustion dish upon interruption of the fuel supply and burnout of the combustible waste oil volume may be pyro-lyzed with the aid of the additionally energizable heat source (23, 28) heating said combustion dish (21).
