Title: Formation of non-toxix medical articles from citrate plasticized pvc
Inventor: HULL EZEKIEL H
IPC: C08K5/11
Filed: 1985-06-10
Granted: 1992-01-07
Abstract: ABSTRACT OF THE DISCLOSURE        Citrate  esters  are formed  utilizing  organic  titanates as a catalyst  allowing  excess  alcohol to be removed.  Four citrate esters have  been  found which provide advantageous plasticizing properties to PVC  compositions  which  include  superior  toxicity  test results and superior  soapy water extraction test results.  The four citrate esters are:     acetyltri-n-hexyl   citrate,   n-butyryltri-n-hexyl   citrate, acetyltri-n-(hexyl/octyl/decyl)  citrate, and acetyltri-n-(octyl/decyl) citrate.   Articles  formed  from  the  PVC  plasticized  mixtures  are extremely   useful  in  the  medical  or  health  care  field  as  they demonstrate a low order of toxicity.

Abstract: Abstract of the disclosure:        The invention relates to a non-toxic conjugate vaccine against infections by Gram-negative bacteria, composed of a species-specific polysaccharide and a protein which are covalently linked together, it being characteristic of the vaccine that the polysaccharide originates from the endotoxin of the bacterium and the protein is an exoprotein.   The vaccines according to the invention are, in particular, vaccines against infections by Pseudomonas aeruginosa or Escherichia coli.        The exoprotein is, in particular, an exotoxin or exotoxoid, preferably toxin A from Pseudomonas aeru-ginosa, but also a tetanus toxoid or diphtheria toxoid.        The process for the preparation of the new con-jugate vaccine against infections by Gram-negative bacteria comprises covalent linkage of an appropriate polysaccharide from the endotoxin of the bacterium with an exoprotein.        However, the invention also relates to a con-jugate vaccine composed of a mixture of 3-15 conjugates whose polysaccharide have (sic) been obtained from 3-15 different serotypes of the same species of bacteria.        The invention further relates to a polyvalent vaccine composed of a mixture of conjugate vaccines, each of whose individual components raises antibodies against a particular species of bacteria. The invention further relates to the use of the new conjugate vaccines for the preparation of hyper-immune sera which in turn are used for the preparation of immunoglobulin which can be administered intra-venously or intramuscularly.

Title: Aspiration syringe
Inventor: CLEMENT THOMAS P
IPC: A61B10/02
Filed: 1988-01-11
Granted: 1993-04-20
Abstract: ASPIRATION SYRINGE      Abstract An aspiration syringe suitable for one-handed operation has a barrel defining a bore, a plunger consisting of a small cross-section plunger shaft extending into the bore and a first seal within the bore, carried by the distal end of the shaft for axial movement within the bore, and an end closure across the bore proximal of the first seal, the plunger shaft extending in sliding, sealed engagement therethrough. The first seal engages the wall defining the bore in vacuum-tight sealing engagement.  The transverse cross-sectional area of the shaft is much less than the transverse cross-sectional area of the bore to provide a syringe-actuating vacuum chamber of substantial volume within the bore between the seal and the end closure. Movement of the plunger shaft to carry the first seal distally, from a first position, away from the end closure, creates a vacuum condition within the vacuum chamber sufficient that when the plunger shaft is released, the first seal is propelled by pressure differential acting across the first seal, while the distal end of the syringe is exposed to fluid, to automatically move the plunger proximally toward the end closure and cause entry of fluid into the distal portion of the bore distal of the first seal.  A method of drawing fluid samples is also described.

Title: Cable transport installation

Filed: 1988-03-24
Granted: 1991-06-11
Abstract: INVENTORS: FRITZ FEUZ and WALTER BRAWAND       INVENTION: CABLE TRANSPORT INSTALLATION     ABSTRACT OF THE DISCLOSURE     The revolving cable transport installation, for instance a gondola aerial cableway, has the carriages of the gondolas supported upon two adjacently extending support cables.  Between both support cables there is arranged a continuously revolving traction cable.  Along the travel path the carriages are coupled with the continuously revolving traction cable by actuatable cable clamps.  These cable clamps are connected with the carriages so as to be elevationally movable and they engage the traction cable from below.  The traction cable extends at the upper region of the carriages and can support itself within the suspension zones, i.e. between the support masts at the carriages.  Thus, the weight of the traction cable does not load the cable clamps and these cable clamps can accommodate themselves to the position of the traction cable independent of the carriages.     Due to supporting of the carriages at two support cables, the cable transport installation is less sensitive to wind loads and there results a quieter and stabler travel of the gondolas.

Abstract: In a process for producing poly (p-phenylenesulfide) from an alkali metal sulfide and a p-dihalobenzene, a product polymer of an advantageously increased molecular weight is obtained by:  providing a mixture comprising an alkali metal sulfide, a polar aprotic solvent, a sodium salt of an aliphatic carboxylic acid represented by the general formula:          RCOONa (where R is an aliphatic hydrocarbon group having 1 -20 carbon atoms), the content of water present in said mixture apart from any water of hydration or crystallization which may be contained in said sulfide and sodium salt being in the range of 5 to 20 moles per mole of said sulfide; thermally dehydrating said sulfide component in said mixture by removing at least part of the water from said mixture; and then contacting the resulting dehydrated mixture with a p-dihalobenzene.  The present process allows the use of inexpensive sodium salts (RCOONa) as compared to lithium salts used in the prior art to increase the molecular weight of the product.
