Abstract: DEVICE AND METHOD FOR COLLECTING AND PROCESSING FAT TISSUE AND PROCURING    MICROVESSEL ENDOTHELIAL CELLS                 ABSTRACT OF THE DISCLOSURE A  device  is  provided,  and  a  method,  for collecting  and  processing  tissue  to  produce  an endothelial  cell  product  having  a vessel  for rinsing, draining, digesting and isolating tissue. The vessel has a rinsing and digesting chamber for containing tissue during processing.  An inlet in the rinsing and digesting chamber allows entry of rinsing  solution  and  tissue  from  liposuction means.  A drain chamber is in the vessel and is in fluid communication with the rinsing and digesting chamber.  The drain chamber connects with a vacuum source.   A  screen  in  the  vessel  separates  the rinsing  and  digesting  chamber  from  the  drain chamber to allow filtered transfer.  An isolation chamber  in  the  vessel  is  separated  by  another screen.  A channel in fluid communication with the isolation  chamber   includes   a  pair   of   ports controlled by valve  means  to  be  selectively  in fluid  communication  with  the  channel.    After processing, the channel has a pellet of microvessel endothelial cells and the valve means may place the pellet  of microvessel  endothelial  cells  in  fluid communication with the ports.  The method includes providing  the  vessel,  introducing  tissue  to  be processed,  orienting  the  vessel  to  screen  the tissue,  introducing  an enzyme  and  agitating  to digest  the  tissue,  centrifuging  the  vessel  to transfer the cells from the digested tissue,  and isolating the cells for retrieval.

Title: Vital railway signal link with photo-emission means
Inventor: MOKKAPATI CHINNARAO
IPC: G08C23/06
Filed: 1993-04-16
Abstract: A vital railway signal link for passing DC signals between a first terminal location and a second terminal location.  A transmitter at the first terminal location receives a DC input signal and responsively produces a light signal modulated at a preselected frequency.  The light signal is conducted through an optical fiber to the second terminal location.  There, a receiver detects the light signal and produces a DC output signal.  The receiver contains discriminator circuitry preferably including a bandpass filter to prevent light signals other than those modulated at the preselected frequency from giving an output signal.

Filed: 1993-04-27
Abstract: A receiver dryer for an automobile air conditioning system embodies a cylindrical housing having a spin-closed top end; an inlet tube and an outlet tube inserted in holes drilled in the top end of the housing and both extending through the housing to their respective predetermined positions; and an axially inserted desiccant bag and thermoplastic perforate filter.  The outlet tube extends through a hole in the filter to a predetermined position from the bottom end of the housing, and a retainer clip holds the filter at a set position in the housing while the bottom end of the housing is spin-closed.  Spin closing the bottom end creates a thermal gradient in the wall of the housing such that the thermoplastic perforate filter is thermally bonded at its edge to irregularities of the inner surface of the housing thereby forming a barrier to any particulates which might otherwise have passed by the filter.

Filed: 1993-06-28
Abstract: CHLORIDE ASSISTED HYDROMETALLURGICAL COPPER EXTRACTION                ABSTRACT OF THE DISCLOSURE           A process for the extraction of copper from a sulphide copper ore or concentrate comprises subjecting the ore or concentrate to a first leaching at an elevated temperature and pressure in the presence of oxygen and a lixiviant which comprises an acidic solution of chloride and sulphate ions to produce an insoluble basic copper sulphate.  The basic copper sulphate so produced is leached in a second leaching preferably at atmospheric pressure with an acidic sulphate solution to dissolve the basic copper salt to produce a leach liquor containing copper sulphate in solution.  The resulting leach liquor is subjected to solvent extraction to produce a copper concentrate solution and a raffinate comprising protons and sulphate ions in solution.  Protons and sulphate ions are extracted from the raffinate to produce a sulphuric acid solution which sulphuric acid solution is then recycled to the first leaching at elevated pressure and temperature to serve as a source of sulphate ions in the lixiviant.  According to a preferred embodiment, the extraction of the protons and sulphate ions from the raffinate is effected by means of an electrodialysis process.  In alternative embodiments copper sulphate is also extracted from the raffinate and recycled to the first leaching step or alternatively a source of sulphate ions, such as a hydrolyzable metal sulphate is introduced from another source.

Title: Sole construction for a sport shoe

Filed: 1993-10-01
Abstract: (57) Abstract The invention concerns a sole construction for a sports shoe, comprising a wear sole as well as, be-tween the upper of the shoe and the wear sole, a resilient layer (13). The resilient layer (13) in the sole construction is throughout made of a substan-tially homogeneous material of invariable hardness, in which layer, in the areas of the heel and of the foot arch, perforations (16) have been formed which extend through the resilient layer (13) from the upper to the wear sole so as to produce the desired properties of resilience and attenuation and the de-sired support effect in the sole construction. The perforated area (16), in relation to the area of the resilient layer (13), has been formed largest in the area of the rear part of the heel so as to make the elasticity and the attenuation of the sole construction maximal in this area, whereas, when moving from said area forwards towards the area of the foot arch, the perforated area becomes smaller and the non-perforated area (17) becomes accordingly larger so as to increase the support effect of the sole construc-tion.

Abstract: SUMMARY Method and device for discrete-time signal interpolation Of  particular  application  in digital  processing  systems  that require oversampling.    As a first step in the method a derivative of generic order "n" of the  input  signal  to  be  interpolated  is  taken;  subsequently  the interpolation  process  itself takes place on the samples of  the  n-th derivative  of  the signal, and finally integration of  the  previously interpolated signal, to the same order "n" as the derivative is done.    The device implements the method described.   (Figure 1)
