Title: Apparatus for uniformly distributing gas and/or liquid in an underdrain lateral system
Inventor: MAXSON RICHARD CHARLES
IPC: B01D24/22
Filed: 1992-08-07
Granted: 1997-04-15
Abstract: Underdrain lateral system, which is especially adapted for use in a gravity filter bed, includes, as its preferred embodiment,  scallop-shaped  laterals  (26,  126)  having  an upper,  wrapped  wire,  slotted  screen  surface  (28).    The screen  surface  supports  and  retains  the  filter  media particles  (118)  directly,  without  the  necessity  of  an underlying gravel layer, and is itself supported by channel-shaped rod members (34) which are welded to the wires (30). The web portions  (36)  of the channel-shaped rod members perform the function of simultaneously distributing air and water during backwashing, and include a smaller total area of apertures (38) in upper channels and a larger total area of apertures (40) in lower channels to cause a plenum (56) to be formed inside the laterals which ensures that the distribution of air and water will be uniform throughout the lateral,  even  if  the  lateral  is  not  perfectly  level. Distribution of the air and water throughout all of the laterals is made even more uniform by mounting the laterals on a header (124) and providing perforated flow tubes (122) which extend from each lateral into the header to produce an additional air plenum (135) therein.

Title: Method for improving the printability of web offset paper
Inventor: CASON DAVID B
IPC: D21G1/00
Filed: 1992-10-14
Granted: 1997-03-25
Abstract: Web offset printing paper having a high level of gloss and smoothness is prepared by finishing a paper web, either by supercalender or with a synthetic roll calender at a moisture content greater than the moisture content typical-ly used for web offset finishing, and then drying the web to a moisture content of less than about 3.5% using convection, radiation or conduction.  Under the preferred post-drying conditions, bonding of the previously wet paper fibers takes place to lock in the desirable printing characteristics and to prevent heat roughening on the offset press.

Title: Method for cooling carcasses
Inventor: PALBISKI CLAY
IPC: F25D3/11
Filed: 1992-11-25
Granted: 1998-04-28
Abstract: A method for chilling carcasses which comprises the steps of introducing a cryogenic fluid into a rotatable drum of a meat tumbler, the drum having inner walls which are cooled  by the cryogenic  fluid;  placing carcasses to be chilled inside the drum; and rotating the drum so that the carcasses contact each other and the inner walls until they are chilled to a sufficient degree.   The cryogenic fluid cools the drum to a temperature of approximately 32°F.  A small quantity of water may be introduced into the drum of the tumbler either immediately before or immediately after the introduction of the cryogenic fluid.  The water forms an ice layer on the inner walls to prevent the carcasses from sticking to the inner walls.   The primary chilling of the carcasses takes place between the tumbling carcasses and the cold inner walls and/or ice layer.  The carcasses may also be tumbled in the drum in an inert gas or vacuum atmosphere to massage surface moisture back into the carcasses.

Title: Split cylinder catheter attachment device
Inventor: FENTON PAUL V JR
IPC: A61M25/02
Filed: 1991-09-13
Granted: 1996-09-10
Abstract: A bayonet twist locking connector (10) for detachably securing an end of a catheter (20) to a fluid transfer device including a flange (38) defining a T-shaped opening for receiving the device and a fluid port (37) extending outwardly along a central axis (37a) of the opening. The connector includes a slit (48) in a resilient body (12) which defines an aperture (26) for receiving an end of the catheter. The body being split allows the aperture to be enlarged to facilitate insertion of the catheter. The connector further includes a bayonet assembly (14A, 14B) for twist locking the connector in the opening of the fluid transfer device, and comple-mentary wing elements (16A, 16B) radially projecting adjacent to the slit for clamping together and against a region of the fluid transfer device. So clamping the complementary wings prohibits the connector from being removed from the opening, and gen-erates a compressive force to secure the catheter to the port of the fluid transfer device.

Abstract: An encapsulated gel breast prosthesis and method of manufacturing therefor is provided wherein a nipple/areola member and gelled breast body are disposed within an inner skin and outer skin which define the exterior shape of the breast prosthesis. The nipple/areola member has a shape, color and hardness simulating the natural shape, color and hardness of a human breast.

The outer skin is shaped to simulate the natural contour of a woman's breast and includes a region corresponding to the nipple and areola of the breast. A nipple/areola member having a shape, color and hardness, which simulates the natural shape, color and hardness of a woman's nipple and areola is disposed between the outer and inner skins which are then sealed together along their peripheries. This forms a capsule with the nipple/areola member enclosed therein. The capsule is then filled with a gel-forming composition through an opening in the capsule.      The opening is sealed and the gel-forming composition is cured into a gel with the nipple/areola member adjacent to the nipple and areola portion of the outer skin.

Abstract: A method of reducing surface irregularities in paper machine headbox components such as the apron floor. A lap having a working surface diameter greater than the dominant dimensional characteristic of the irregularities is provided.  The lap's working surface is machined flat to a tolerance equivalent to a desired flatness tolerance of the apron floor.  A central, circular portion of the lap's working surface is counterbored to define an outer, annular cutting region on the lap's working surface.   The apron floor is  levelly  supported and measured to obtain an initial profile of surface irregularity as a function of position on the apron floor.   The lap is then driven to rotate its cutting region levelly on and over the apron floor while abrasive material in solid form and a coolant are applied between the lap and the apron floor.  The apron floor is again measured to obtain an updated profile of surface irregularity as a function of position on the apron floor.  The lapping and measuring steps are repeated with progressively  finer grades  of  abrasive material  until comparison of the initial and updated profiles reveals attainment of the desired flatness tolerance of the apron floor.  The procedure can be repeated at corner regions of the apron floor by substituting for the lap a corner lap having a working surface diameter significantly less than the apron floor width.

IPC: G01B21/04
Filed: 1994-08-03
Granted: 2000-01-25
Abstract: In a method of positioning a work piece carrier member with regard to a machining apparatus, it is provided to insert the work piece carrier member into the machining apparatus and to fix it there in a position which at least approximately corresponds to a desired nominal position. Thereafter, the effective position of the work piece carrier member is determined by scanning two reference marks provided on the work piece carrier member. The determination of the exact position of the work pieces received in the work piece carrier member is carried out in a separate measuring and aligning station. The positional data thus determined are transferred to the machining apparatus. The effective position of the work pieces received in the work piece carrier member can be calculated on the basis of the position of the reference marks.      The invention further provides a work piece carrier member comprising at least two reference marks located in a certain horizontal distance from each other. Thereby, the exact effective position of the work piece carrier member in X- and Y-direction as well as regarding its angular orientation around the Z-axis can be easily determined. Thereby, the need is removed to bring the work piece carrier member in an exactly predetermined position with regard to a machining apparatus.
