Abstract: BODY REST WITH MEANS FOR PREVENTING PRESSURE SORES       ABSTRACT OF THE DISCLOSURE            A body rest such as a bed with means incorporated for avoiding the development of pressure sores (decubitus ulcer) caused by prolonged local pressure against a patient's body. The bed comprises: a matrix of freely vertical displaceable supports, in the form of free-floating, pressurized air-supported pistons, constituting together the continuous couch surface of the bed.  The pressure exerted by the patient's body sections against their respective support pistons is constantly measured.  Valves are provided associated with and controlling the discharge of the air from the piston chambers under the presssure applied to each one of the respective support pistons. After a preset time and level of pressure prevailing within a given piston chamber, a fixed amount of air is discharged, thereby partly relieving the pressure and causing the downward displacement of the respective piston.  At the end of the cycle, all the pistons are brought back to their initial, common high level.

Abstract: These hides, completely free from chromium, have a moisture content of between 15 and 20%, a maximum inorganic matter content of 10 +/- 2%, an aluminium oxide content of 0.7 +/- 0.2% and an acrylic derivatives content of approximately 2%. Their pH is in the region of 4.0% and their dermic substance content is approximately 85 +/- 3%. They are capable of being rewetted in less than an hour. The process for obtaining them, of the type consisting in subjecting the completely delimed and bated hides to a pickling treatment in the presence of acrylic resin and then, after a rest, to a pretanning treatment with the aid of aluminium salts, is characterised in that there is introduced at any stage of the treatment a chemical agent facilitating the rewetting and enabling the hide to retain, after drying, a residual moisture close to 20% and in that the hide thus treated is subjected to drying. This chemical agent is chosen from the group consisting of polyalcohols, condensates of fatty alcohols with ethylene oxide and condensates of alkylphenols with ethylene oxide.

Title: Degradable plastics based on polyolefin/polydiene blends
Inventor: GRIFFIN GERALD J L
IPC: C08L101/00
Filed: 1988-05-20
Granted: 1995-03-28
Abstract: A  degradable  polymer  composition  is  disclosed which comprises a blend of a normally stable chemically saturated polymer, such as polyethylene, a less stable chemically unsaturated polymer or copolymer, such as a styrene/butadiene block copolymer, or natural rubber, an antioxidant active over a limited period and a latent pro-oxidant,  such as an organic salt of a transition metal, e.g. cobalt naphthenate.  The presence together of the  anti-oxidant  and  the  pro-oxidant  give  rise  to a period of  induction before a  sharp  loss  of  physical strength occurs, whereby the period of induction can be exploited as the effective working life of the polymer composition.   The polymer composition preferably also includes  filler  particles  of  a  directly  biologically sensitive material such as natural starch, a derivative of  natural  starch,  a  natural  protein  or  a  natural cellulose product or a powdered sugar of melting point higher  than  the  processing  temperature  of  the  host polymer composition, whereby, the biological breakdown, in natural environments or in the especially biologically active surroundings of composting urban garbage, of the molecular fragments created by the onset of oxidative scission  of  the  molecular  chains  of  the  chemically saturated polymer is accelerated by the presence of said filler particles.

Granted: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE      A digital data transfer system for transferring baseband digital data between a central location and a patient's room is provided.  The system employs the existing coaxial cable network found in hospitals and other institutions.  The coaxial cable carries power from a DC power source to the patient's television receiver or other device.  Digital data is addressed and  transmitted  from the  central  location to  the individual patient's room on the coaxial cable by temporarily disconnecting the DC power source from the  coaxial  cable  for  each  bit  which  is  to  be transferred (source switching) and detecting, in the patient's room, the interruption in the flow of DC current  through  the  cable.     Digital  data  is transmitted  from  the  patient's  room  back  to  the central location on the same single coaxial cable by temporarily  disconnecting  the  load,   e.g.,   the patient's television receiver or other device, from the  coaxial  cable  for  each  bit  which  is  to  be transferred back (load switching) and detecting, at the central location, the interruption in the flow of DC current through the cable.  A storage capacitor is placed in parallel with the load to provide power for the load while the flow of DC current is interrupted. The system can readily achieve transmission rates on the order of 38 kilobaud and above.

Abstract: ABSTRACT   A powder material and a process for producing the material are disclosed  The powder material consists essentially of spherical particles selected from the group consisting of metals, metal alloys, ceramic glasses, crystalline ceramic materials,  and   combinations  thereof  The material is essentially free of elliptical shaped material and elongated particles having rounded ends  The material has a particle size of less than about 20 micrometers in diameter and  has an oxygen content of less than about 0.8% by weight. The process for making the spherical particles involves reducing the size of a starting material to produce a finer powder essentially all of which has a particle size of less than about 20 micrometers in diameter.  This is done by fluid energy milling. The finer powder is entrained in a carrier gas and passed through a high temperature zone at a temperature above the melting point of the powder, the temperature being from about 5500°C to about 17,000°C and created by a plasma jet, to melt at least about 50% by weight of the powder and form spherical particles of the melted portion.  The powder is then rapidly and directly solidified while in flight.  The carbon content of the particles is no greater than that of the starting material.
