Title: Antimicrobial coated implants
Inventor: DE LEON JOSE L
IPC: A61K6/884
Filed: 1988-08-30
Granted: 1994-03-29
Abstract: ABSTRACT         Uniform adherent coatings of antimicrobial agents are applied to the surface of implants by apply-ing a film of silicone oil to the surface of the implant and contacting the film-bearing surface with antimicro-bial agents in a film-adherent form.  A durable antimi-crobial coating is formed.  The coated implants can be packaged using mechanized implant handling equipment without significant loss of the antimicrobial coating.

Granted: 1992-12-29
Abstract: PORTABLE TOILET CABANA                     ABSTRACT OF DISCLOSURE   A portable toilet cabana is formed of four, wide, relatively resilient sheet plastic walls whose adjacent vertical edges are connected together by narrow sheet plastic panels that are roughly a quarter of the width of the walls to form an octagon-like enclosure with alternating wide and narrow sides. The widths of the walls are close to the maximum width limit at which the walls tend to buckle, so that the panels enlarge the enclosure. The adjacent edges of the walls and panels are bent into flanges that are interconnected. A vertically-extending channel is bent along the middle portion of each panel, and a vertically outwardly-extending channel is bent close to each of the edges of the walls, so that the channels and connected flanges form reinforcement columns for the cabana.

Abstract: ABSTRACT        The  invention  relates  to  a process  for  the manufacture of molded articles made from thermoplastic molding compound, by heating of the latter, molding of a blank by means of an annular, if need be, die; sepa-ration of the blank by using a heated stream of gas, such  stream  of  gas  surrounding  the  die  and  being directed at the point of separation;  introduction of the blank in a compression-molding mold;  closing of the mold; shaping of the compressed article by appli-cation of a compression pressure; and cooling of the molded  article  at  least  partly  under  pressure.         According to the invention, the total amount of heated thermoplastic molding compound needed for a blank is deposited on the surface of an intermediate support, such surface forming part of the mold, and such inter-mediate  support being  extended  under  the  die,  and separated from the die, whereby the intermediate sup-port is lowered as the mold is being closed.   The invention, furthermore, relates to a device for carry-ing out the process of the invention, with an extruder for heating thermoplastic molding compound, and with a closable die (1) suitable for dispensing portions of the molding compound, such die being annular, if need be, and surrounded by and annular nozzle (4), if nec-essary, for feeding a stream of gas against the point at which the portions of molding compound are sepa-rated from the die (1), which stream of gas may be heated; and with at least one closable mold consisting of a molding matrix (5) and a molding mandrel  (13), such molding matrix (5) being arranged under the die (1), on the one hand, and coaxially with the molding mandrel (13), on the other hand;  and whereby a com-pressing pressure is applicable to and maintainable on the molding mandrel  (13)  and/or molding matrix  (5).          According to the invention, an extendible intermediate support (8) is arranged in the molding matrix (5), the free surface (11) of such support,  in the retracted position of the latter,  forming part of the shaping surface  of  the  matrix  (5) reproducing  the  molded article.

Title: Ultrasonic velocity sensor
Inventor: HINIKER THOMAS K
IPC: G01S7/52
Filed: 1989-03-15
Granted: 1992-04-21
Abstract: ABSTRACT An ultrasonic ground speed sensor has a single transducer which both transmits and receives ultrasonic signals.  The sensor is mounted on a vehicle in align-ment with the direction of the vehicle, the transducer having a built-in angle with the body of the sensor unit.  The transmitted signal is clocked by a 16 MHz clock, with the signal received by the transducer selec-tively filtered and amplified.  A temperature sensor is also used to determine the speed of the transmitted and received signal.  A 64-cycle sample period is used, as well as multiple counters and a signal processor to increase accuracy and minimize erroneous readings.  A drop-out detector and monitoring system sensor is also described.  The vehicle speed is calculated from a Doppler-based formula as a function of both the sum and difference of the transmitted and received signal fre-quencies.  Also disclosed is a gasket seal having leak holes for drainage from the interior of the sensor.

Abstract: INTEGRATED PAVER WITH WINDROW PICK-UP CAPABILITY  ABSTRACT OF THE DISCLOSURE             An integrated paver comprising a self-propelled chassis having a paving apparatus, such as a screed, supported on its rear end and a lifting conveyor supported on its front end.  The conveyor is capable of picking-up loose paving material laid in the windrow on the road surface. It is pivotally supported on a mounting which is in-turn pivotally supported on the chassis such that the conveyor can be adjusted in two dimensions relative to the chassis.  Grade controls on the conveyor control hydraulic cylinders to adjust the tilt and grade of the conveyor relative to the road surface.      Alternatively, the conveyor can rest, by force of gravity on runners which slide along the ground and hold the conveyor head a predetermined height (possibly zero) above the ground.      Additionally, the runners can be linked to floating break-away scrapers which are maintained at a set position relative to the runners.  The conveyors drage chain rides over an idler shaft above and in front of the inlet end supporting shaft of the chain such that the paddles on the chain travel at close to 45° to the road surface to reduce vibration and the slapping action of the paddles against the windrow.

Abstract: To avoid an unacceptably high exhaust gas back pressure when operating diesel engines equipped with a particle filter in the exhaust gas stream, an engine lubricating oil is used that has a catalytically active content of an iron compound in an amount of 5 to 20,000 ppm. The use of the additive facilitates the regeneration of the diesel particle filters by burning, especially under operating conditions of the diesel engine that lead only to relatively low exhaust gas temperatures. Iron compounds proposed are ferrocene, ferrocene derivatives, and iron salts of organic acids.
