Filed: 1988-08-27
Granted: 1997-06-09
Abstract: A resilient squeeze bottle dispensing package capable of dispensing viscous products without excessive air entrainment and belching on successive dispensing cycles. In a preferred embodiment, the viscous product (60) is preferably suspended inside a resilient squeeze bottle (12) in a thin flexible bag (10). The flexible bag (10) is secured about its perimeter to the interior of the squeeze bottle at its top (14) and approximately at its midpoint (11) to facilitate both complete emptying of product and desirable suckback characteristics when the opposed squeezing forces are removed from the resilient outer wall of the bottle. A suckback valve (30) is located between the dispensing orifice (20) in the shroud of the package and the flexible bag (10) to limit the amount of air which can enter the package through the dispensing orifice (20) at the conclusion of each dispensing cycle and to prevent slumping of viscous product remaining in the shroud (22) into the bottom of the flexible bag (10) between dispensing cycles. An air check valve (1) is preferably provided in the bottom (2) of the resilient squeeze bottle to facilitate a pressure buildup within the bottle when opposed squeezing forces are applied thereto.

Title: Manufacturing method of multi-layer ceramic condenser by using injection electrode method
Inventor: KIM YUN-HYO
IPC: H01G4/12
Filed: 1990-04-07
Granted: 1992-08-20
Abstract: The method comprises producing a pore layer by  stacking  and sintering  dielectric  layers  (1)  applied  with  quasi-electrode material (2). The pore layer, oxidised by  sintering,  is  reduced and then molten metal is permeated into the interion of  the  pore layer  without  applying  high  pressure.  The  pore  layer  after sintering  is  formed   with   NiO   by   using   a   mixture   of 2NiCO3-3Ni(OH)2-4H2O and carbon black as quasi-electrode material. Pb, Sn or Pb-Sn  alloy  is  the  molten  metal  for  the  internal electrode. The NiO surface forming the pore layer is reduced to Ni so as to increase the surface energy and enhance contact with  the other metal.

Title: Decoder for variable-number of channel presentation of multi-dimensional sound fields
Inventor: DAVIS MARK F
IPC: G06F9/445

Abstract: In an encoder, multiple channels of audio information representing multidimensional sound fields are split into subband signals and the subband signals in one or more subbands are combined to form composite signals. The composite signals, the subband signals not combined into a composite signal and information describing the spectral levels of subband signals combined into composite signals are assembled into an encoded output signal. The spectral level information conveys either the amplitude or power of the combined subband signals or the apparent direction of the sound field represented by the combined subband signals. In digital implementations, adaptive bit allocation may be used to reduce the informational requirements of the encoded signal.

Title: Paper making belt and method of making the same using a textured casting surface
Inventor: SMURKOSKI JOHN ANDREW
IPC: B29C35/08

Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by casting a photosensitive resinous material over and through the reinforcing structure while the reinforcing structure travels over a textured surface, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions. A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.
