Title: Tocopherol-based pharmaceutical systems
Inventor: JANOFF ANDREW S
IPC: A61K31/415
Filed: 1988-10-19
Granted: 1994-12-06
Abstract: A method for making a pharmaceutical composition is described.  The composition is comprised of an organic acid derivative of alpha tocopherol, and may additionally comprise other lipids.  The composition may be in the form of liposomes, and as such are associated with or entrap a bioactive agent. Particularly suited for such systems are drugs stable at acidic pH, for example drugs having imidazole groups, such as pilocarpine.  The composition requires a stabilizer to maintain the bilayer phase of the organic acid derivative of alpha tocopherol in a low pH environment.  Such a stabilizer is for example a detergent.  Upon in vivo administration of the system and concomitant increase of pH, viscosity of the preparation increases.

Title: Passive dental appliances of fiber-reinforced composites
Inventor: GOLDBERG A JON
IPC: A61C13/00
Filed: 1988-11-10
Granted: 1992-07-07
Abstract: ABSTRACT    Nonforce-imparting or passive dental components and appliances are provided possessing not only greater stiffness and strength but also generally higher mechanical properties than those exhibited by the commonly used dental polymers.  They also are more esthetic and easier to process, form and adjust than dental metallic alloys, thereby allowing for  superior and unique designs.  The passive dental appliances or structural components are fabricated from an effective fiber reinforced composite material comprised essentially of a polymeric matrix and a fiber component embedded within the matrix.  "The fiber component of the composite material constitute  greater than 20 percent by weight of the composite material and the modulus of elasticity of the composite is greater than 0.5 x 106 psi.  The passive components are produced by initially compounding an effective fiber-reinforced composite material having the requisite stiffness and strength characteristics, fiber orientation and void free wetting of the fibers and thereafter forming the composite into the dental device to achieve improved aesthetics coupled with ease of processing and structural stability.

Abstract: ABSTRACT OF THE DISCLOSURE:          The device for effecting the adjustment of the orientation of a steering wheel on a shaft, which are joined together by fastening means,  comprises a sleeve interposed between the end  of the shaft and the hub of the steering wheel.  The sleeve and the shaft define between them an annular chamber in which is housed a friction member opposing their spontaneous relative rotation.  The fine adjustment, limited to a value of about 9°, is made with the aid of an arrangement which comprises a control mechanism, amplitude limiters,  and stops.   These stops ensure continuity of transmission of the torque exerted on the steering wheel to the shaft in the event of the slackening of the fastening means or failure of the amplitude limiters.

Abstract: IMPROVED SAFETY TROCAR     Abstract of the disclosure:    A safety trocar is provided which includes a spring-loaded shield that shields the cutting tip of the obturator after the obturator penetrates tissue.  The distal end of the shield is hemispheric in profile and contains a slot which conforms to the geometry of the cutting tip.  The rounded distal end enables the shield to spring forward to shield the cutting tip as soon as the tip perforates the tissue.  A valve is located at the proximal end of the trocar tube to seal the end of the tube.  The valve is oriented at an acute angle with respect to the longitudinal axis of the trocar tube.  The valve is controllable by an external lever which will hold the valve open or permit it to spring shut.  An incremental advancement mechanism cooperates with the obturator to permit only incremental advance of the obturator.  Instead of using a discrete shield component the shielding function may be provided by spring-loading the trocar tube itself to spring forward and shield the obturator tip after the tip penetrates tissue.
