Granted: 1991-08-20
Abstract: IMPLANTABLE FILTER Abstract of the Disclosure A blood clot filtration device, for implantation percutaneously, for preventing movement of blood clots within a blood vessel.  The device has a head and a plurality of legs extending therefrom.  The legs include a first linear leg portion of predetermined length emanating distally from the head generally parallel to the axis of the device; a second multi-angled leg portion of relatively greater length extending generally outwardly from the distal end of the first linear leg portion at an acute angle to the axis, to form, with other second leg portions, a conical aspect, the second leg portion having a series of discrete linear segments arrayed generally tangent to a cone defined by the second leg portions of the set of legs; and a hook portion at the distal end of each the leg extending outwardly, away from the axis in a manner for engaging the blood vessel to fix the position of the device therewithin.  The configuration of the legs, including the first linear portion, and the use of a high strength titanium alloy for the head, formed by fusing, and legs produces a filter which is able to tolerate severe compression for introduction percutaneously through a small sheath without yeilding. Preferably a central wire segment is disposed axially, with the first linear leg portions of the filter disposed closely thereabout.

Patent CA-1289045-C (CA)
Title: System for regulating the inflation of tires
Inventor: CUNNINGHAM CHARLES L
IPC: B60S5/04
Filed: 1988-08-17
Granted: 1991-09-17
Abstract: ABSTRACT           An improved system is provided for use with a tire changer to regulate and control the inflation of pneumatic tires.  This system regulates the flow of air in an air supply conduit through which pressurized air flows from a supply source to an outlet such as an air hose and chuck which an operator connects to a pneumatic tire.  The system includes a first and a second valve serially connected to the air supply conduit.  A foot pedal activating member opens the first valve and closes a switch which activates a timer.  The timer opens the second valve for a first predetermined time period and then maintains it in a closed position for a second predetermined time period.  During the first period, the air flows through the conduit under relatively high pressure to inflate a pneumatic tire.  During the second period, the second valve prevents the flow of air so that the system may stabilize and indicate the pressure in the pneumatic tire.  Tire pressure is sensed by an air gauge connected to the air supply conduit and also by a high pressure switch.  The foot switch is a reset switch which does not initiate an inflating/measuring cycle unless the operator releases the activating member and then again actuates the reset switch.  If the high pressure switch indicates a tire pressure above a preset maximum, then further actuation by the foot pedal will be ineffective.

Inventor: SAURWEIN ALBERT C
IPC: B05B15/68
Filed: 1988-10-11
Granted: 1993-06-22
Abstract: ABSTRACT OF THE INVENTION    A high pressure water/abrasive jet cutting nozzle has a pair of centering rings that act through body-mounted balls to position a nozzle element-holding collet.  The interior surfaces of the centering= rings are eccentric with respect to the longitudinal axis of the nozzle assembly so that rotation of a centering ring will cause the nozzle element collet to shift transversely.  By rotating one or the other, or both, centering rings the axis of the nozzle element can be adjusted relative to the nozzle jet-forming element so as to align the nozzle element with the water jet.

Title: Method of refining ferrous ion-containing acid solution
Inventor: FUKUSHIMA TSUTOMU
IPC: C23G1/36
Filed: 1988-12-09
Granted: 1995-11-07
Abstract: According to the subject method of refining a ferrous ion-containing acid solution, a metal selected from a group including A?, Cr, V, B, and Zn or an acid solution of that metal is added to a ferrous ion-containing acid solution, such as an acid solution which remains after steel is washed with an acid.  The pH value of the acid solution is controlled to be within the range of 3.5 to 6 by adding an alkali liquid to the acid solution, whereby a hydroxide salt of the added metal is produced in the acid solution and the impuri-ties in the acid solution are captured by the produced hydroxide salt.  As a result, the impurities can be eliminated from the acid solution such that the Si com-ponent (e.g., SiO2) content in the acid solution is within the range of 2 to 3 ppm or less.  Since the con-tent of the other impurities such as A?, Ti, and Cr can also be reduced, a high-purity iron oxide can be obtained from the resultant acid solution.

Abstract: REDUCTION OF NEUROTOXIC EFFECTS OF CYTOTOXIC AGENTS                         ABSTRACT Intracranial abnormal solid cellular masses, particularly tumors or adjacent tissues that may con-tain tumor cells, are treated by administering to the abnormal area a sufficient amount of a cytotoxic drug comprising a vinca alkaloid dispersed in a stable flow-able proteinaceous matrix.  The matrix substantially inhibits the migration of the drug from the site of administration, so as to maintain the primary effect of the drug in the region of administration.  Migration can be further inhibited by the use of physiologically acceptable materials which modify cellular properties or physiological responses to further regionalize the placement of drug at the injection site.

Abstract: ABSTRACT OF THE DISCLOSURE         A throttle control lever for a vehicle, and in particu-lar for a recreational vehicle such as a snowmobile, has a two-stage lever action.  In the first stage, which includes throttle openings corresponding to normal cruising speeds of the vehicle, the throttle lever turns about a first pivot axis wherein the mechanical advantage of the manual actuating force is relatively high.  In a second range the throttle lever pivots about a second pivot axis wherein the mechanical advantage of the manual actuat-ing force is relatively much smaller.  Operator fatigue is reduced because of the reduction in force required at normal cruising speeds of the vehicle.

Abstract: The probe (1) of the measuring device, fed with the needle electric pulse, is constituted of a set of waveguides connected parallely in the embranchment (2) with the microprocessor controller (10) of the electronic assemblies of the measuring device. Waveguides of the probe are installed in chosen layers of the material studied. The directly measured quantity is the sequence of time periods separating subsequent reflections of the electromagnetic wave propagating in the probe from the particular probe impedance discontinuities. The electromagnetic wave propagation velocity in a chosen layer of the medium is calculated on this basis, and therefrom the dielectric constant of the medium, and finally its moisture content upon which the dielectric constant depends. The measuring device according to this invention may be used either for measuring or as an element of a control system, for all the capillary-porous media to which the probe can be inserted, such as: the soil, agricultural products (grain, hop cones, tobacco, hay), semiproducts and final products of the food processing industry (flour, bakery products), wood, moulding sand, subgrades, building foundations etc.
