Abstract: ABSTRACT      The   present   invention   is directed   to   a subcutaneous  peritoneal  injection  catheter  apparatus and methods which minimize catheter obstruction during use.   The apparatus includes a receiving chamber or reservoir  having a  relatively small  internal  volume while employing a penetrable membrane and relatively enlarged  target  surface  area.    The  reservoir  is interconnected with the peritoneal cavity by a hollow stem.   The penetrable membrane accommodates a hollow needle being inserted into the receiving reservoir and is configurated with a dome-like profile so that the membrane may also be depressed to expel insulin from the receiving reservoir into the peritoneal cavity in a direction generally toward  the mesenteric peritoneal membrane.  The portion of the apparatus which is in the peritoneal cavity is preferably constructed of, or coated with, a material which is capable of minimizing the adhesion of cells and the growth of bacteria on that portion of the apparatus.  In a presently preferred embodiment of the subcutaneous peritoneal injection catheter, the portion of the catheter to be within the peritoneal cavity is constructed of a polyurethane material, and this polyurethane material is then coated with a solution of polyurethane and poly(ethylene glycol) in a suitable solvent.

Abstract: RACE CONDITION MEDIATOR CIRCUIT  ABSTRACT OF THE DISCLOSURE         A circuit which eliminates race conditions caused by gate delay variation.  In the absence of gate delay variations data is made available for a period of time which extends beyond commencement of processing of such data.  This circuit prevents gate delay variations from causing processing to commence after the period of time during which data is available.  Each of a pair of flip-flops initiates or terminates the data available time period.  These flip-flops an exclusive-or gate and related circuitry are arranged such that the period of time for data availability is not terminated until after processing of such data actually commences.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to the manufacture of foam from phenolic resins and to the foam  so produced.  In order to overcome some the the limitations of the prior art closed cell phenolic foams, we have developed a method of preparing closed cell foams from modified, low cost phenol formaldehyde resoles, which exhibit high closed cell contents, low friability and low thermal conductivity.  This specification provides a foam competitive with urethane foams, which have an aged thermal conductivity of about 0.16K. or less, but  which will not generate fumes as toxic as those of urethane.  There is, provided a method of making a phenolic foam material comprising the steps of 1)  preparing a base catalysed phenol-formaldehyde resole having a mole ratio of phenol to formaldehyde of between 1:3 and 1:4.5 and containing substantially no free phenol but including residual formaldehyde;          2)  neutralizing, concentrating and acidifying said resole;          3)  reacting with co-reactants consisting essentially of urea and resorcinol in an amount such that the molar ratio of combined urea and resorcinol to free formaldehyde in said resole is about 1:1, the ratio of urea to formalde-hyde being selected so that in a test starting at ambient temperature a reaction temperature of 70° to 75°C. is reached during foaming within a period of 4 to 8 minutes, the urea being reacted first where urea and resorcinol are separately reacted with the resole;          4)  (a)  combining the product of step 3 with a surfactant in an amount sufficient to be effective as a cell stabilizer and (b)  a blowing agent in an amount sufficient to form a foam;          5) initiating foam formation by adding to the mixture of step 4 a catalyst comprising an acidic material to reduce the pH of the mixture to below 4;          6)  curing the mixture of step 5.

Abstract: ABSTRACT   This invention relates to a method and apparatus for the measurement of the flow velocity of a fluid (especially B liquid) and particularly erythrocyte velocity in blood vessels.  The single-frequency laser Doppler velocimeter of the invention comprises a lightway which is exclusively fibre-optic and therefore eliminates the proliferation of air-glass interfaces found in prior art apparatus.  The fibre-optic lightway is a mono-fibre which operates bi-directionally and the Doppler-shifted beam is diverted from the main pathway by means of a fibre-optic tap which is preferably of the same material as the catheter probe.  The mono-fibre is coupled to the laser by means of a low-loss wet mateable connector having a low backscattering coefficient.  By coupling a low-power single-frequency laser with an all-fibre optical section, a number of significant advantages are realized The apparatus is electrically isolated from the patient and imparts minimal energy to the blood so that no damage to blood elements is possible.  The use of mono-fibre optical path with a commensurately small catheter enables very small blood velocities in remote parts of the body to be successfully measured.  The apparatus is rugged, compact and restively inexpensive by comparison with prior-art devices and is ideally suited to manufacture on a large-scale for use in clinical environments where low cost, reliability and accuracy are of special importance.

Granted: 1989-09-26
Abstract: Abstract of the Disclosure An oil pump is disclosed for a motor-driven apparatus and in particular for lubricating the cutting chain of a chain saw.  The oil pump has a pump piston that is rotatable about its longitudinal axis and has a control cam for its axial reciprocation, which as it revolves comes into contact engagement with a control bolt.  A control slide upon which a biasing force is exerted is associated with the pump piston.          The stroke of the pump piston is limited during normal operation by means of the control slide.  If an increased amount of lubricating oil is required, the limitation on the piston stroke effected by the control slide is overcome by moving the control slide away from the pump piston counter to its biasing force, so that the pump piston can move through its maximum total stroke as predetermined by the control cam.
