Filed: 1992-10-08
Abstract: A self contained gas powered endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes an anvil member and a surgical fastener cartridge member mounted to the distal end of an elongated endoscopic portion. A tubular collar of the endoscopic portion moves distally to engage the anvil member and bias the anvil member and the cartridge member into cooperative alignment, thereby clamping body tissue to be fastened between the anvil member and the cartridge member. A self contained pneumatic system is disposed in the surgical apparatus and is actuable to eject and/or form the surgical fasteners in the clamped body tissue. The apparatus further comprises a locking means for preventing firing of the instrument after it has been fired a predetermined number of times. A counter for displaying the number of times the apparatus has been fired may be provided. A firing interlock is also shown which prevents accidental actuation of the firing trigger. A clamping interlock is shown which prevents approximation of the jaws when the jaws are either misaligned or improperly inserted into the instrument.

Title: Core element for catalytic converter
Inventor: SHELLER DAVID T
IPC: F01N3/28
Filed: 1992-11-25
Abstract: ABSTRACT OF THE DISCLOSURE         There is provided an improved core element for use in  a  catalytic  converter,   especially  an  electrically heatable  catalytic  converter,   which  core  element  is characterized by a corrugated thin metal strip having metal tabs attached to each end.  The tabs are bent along one or more lines normal to the edges of the corrugated thin metal strip.   When bent along one line, for example,  an angular tab is formed.   When the tabs are bent along an infinite number of  lines a  uniform amount, a  circular  segment  is formed.  A catalyst is deposited on one or both surfaces of the corrugated thin metal strips.  A central portion of each strip  is  flat  to  enable  location between the  legs of a bifurcated central pin.   The central pin with a group of such corrugated thin metal  strips  is then spirally wound about said central pin to provide a core with overlapped curved tabs defining at least two  discrete generally spiral groups of resistance strips electrically isolated from each other.   The  strips are adapted to be connected in series with a voltage source and encased in a housing to form an electrically heatable catalytic converter.

Abstract: A combined preparation for simultaneous combined, simultaneous separate, or sequential use in the therapy or prophylaxis of disorders associated with undesirably high levels of TNF, e.g. septic or endotoxic shock and immunoregulatory and inflammatory disorders, which comprises an antibody to TNF or a TNF binding fragment thereof and a xanthine derivative. Particular preferred xanthine derivatives are 3,7-dimethyl-1-(5-oxo-hexyl)xanthine (known as Pentoxifylline or Trental) and 1-(5-hydroxy-5-methylhexyl)-3-methylxanthine and similar compounds. The anti-TNF antibody or fragment is preferably monospecific especially a humanised recombinant antibody or fragment. The ratio of xanthine derivative to anti-TNF antibody component used may be in the range between 450:1 and 1:10 and doses of anti-TNF component in the range 0.001-30mg/kg/day and doses of xanthine derivative in the range 0.5 to 100mg/kg/day may be administered during treatment of human or animal subjects.  It has been found that when an anti-TNF antibody and a xanthine derivative are used together in some experimental models of septic shock, a surprising combination effect is observed.

IPC: G03D5/06
Filed: 1991-12-10
Abstract: It is known to apply processing solution to photographic material using a high speed moving surface. High speed rotating drums have been used to transfer processing solution from a reservoir to the material. Horizontal belts are also known. However, such arrangements require large volumes of processing solution in order to operate effectively. Described herein is a processor (1) comprising a vertically mounted high speed belt (10) which both transfers processing solution (26) from a reservoir (20) onto photographic paper being processed, and provides agitation at the paper surface. Two transport belts (30, 32) are provided, one on either side of the belt (10) to assist in the transport of paper through the apparatus. An arrangement according to the invention has the advantages that only low volumes of processing solutions are required, good surface agitation is provided, and it can be fitted into conventional photographic processing apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE           An  extractor  in  which  material  to  be extracted is caused to move by a screw conveyor within a housing  or  trough  in  counter  current  to  an extracting liquid  (extractant).  The motion of the screw conveyor is intermittently reversible, and the gentle  agitation  of  the  raw  material  with  the extracting liquid causes material to be extracted to separate from the raw material and moved with the extactant  to  a  liquids  outlet.  The  housing  is pressurized and the process of the invention run at elevated pressure. Extractant is injected into the raw material using jets on the screw conveyor. A strainer at  the  liquids  outlet  is  charged  with  fine particulates  as  a  filter  medium.  The  housing  is enlarged to assist in gas removal from the housing. Extracted liquids are processed in a like extractor to remove additional fine material, and extracted solids additionally processed to remove further liquids from the solid material.
