摘要:
A scrubber for an automotive vehicle. The scrubber includes a brush, pivot and centering assembly. The brush scrubs the vehicle. The pivot allows the brush to change angular orientation. The centering means urges the brush toward a single predetermined angular orientation. In this way, should a vehicle drive into the brush, the brush may pivot with the force applied to it, reducing the chance that the brush or the vehicle will be damaged. The centering mechanism, however, urges the brush toward a predetermined angular orientation so that, absent an external force applied to the brush, the brush will be in a predetermined position ready for scrubbing the vehicle.

Automatic vehicle washer. The washer includes a vehicle washing apparatus, source of electrical power, manual input, code verifier and activator. The manual input allows a driver of a vehicle to transmit a numerical signal to the code verifier. If the code verifier determines that the numerical signal corresponds to a predetermined numerical code, the energizer interconnects the vehicle washing apparatus with the source of electrical power.

The cannula of a conventional intravascular catheter is placed into the peritoneal cavity through a small shallow incision in antiseptically prepared skin. The stylet or trocar of the conventional catheter is removed; and a stainless steel elongated flexible guide is inserted through the catheter's cannula into the peritoneal cavity. The catheter's cannula is removed and a flexible elongated cannula inserted into the cavity over the guide and secured in place with a suture. Fluid operation means is connected to the elongated cannula by connector means to permit fluid treatment after removal of the guide. Apparatus to effect peritoneal fluid treatment are placed in sterile openable sealed packages for storage and transport.
摘要:
A mold closure assembly for a mounting press for mounting metallurgical specimens in a plastic mount including a cap lockingly insertable in the upper end of the mold, a conical member disposed in a mating conical recess in the lower end of said cap, spring means for urging said conical member into such mating relation, a compression member adapted for a sliding fit in the mold and handle means attached to the cap and foldable to a non-obstructing position to permit a temperature control unit to be attached to or removed from the closure assembly.

Compounds of the formula useful for treatment of disorders of the dopaminergic system, such as schizophrenia, schizoaffective disorder, bipolar disorder, Parkinson's disease, L-DOPA induced pychoses and dyskinesias, Tourette's syndrome and hyperprolactinemia and in the treatment of drug addiction such as the addiction to ethanol, nicotine or cocaine and related illnesses.
摘要:
Methods and apparatus are provided for use in intraoperative and percutaneous procedures for supplying long-term retrograde perfusion of the myocardium via one or more conduits disposed between the left ventricle and the coronary venous vasculature. The conduits are of a selected size and number, and portions of the venous vasculature or coronary ostium are partially or completely occluded, to maintain a parameter related to the pressure attained in the venous vasculature to a value less than a predetermined value.
摘要:
Compounds having dopaminegic activity are provided, having the formula: wherein R1 and R2 are each, independently, hydrogen, C1-10 alkyl, or (CH2)mR4, wherein R4 is phenyl or naphthyl which may be substituted by one or two substituents selected from the group consisting of C1-6 alkyl, halogen, C1-6 alkoxide and trifluoromethyl and m is 1 to 5; and R3 is hydrogen or C1-6 alkyl; or pharmaceutically acceptable salts thereof.
摘要:
Methods and apparatus for supplying retrograde perfusion of chronically ischemic myocardium by forming one or more transmural passageways between a cardiac chamber and the coronary venous vasculature. The placement, size and number of the passageways are selected, and portions of the venous vasculature or coronary ostium optionally partially or completely occluded, to maintain a parameter related to the pressure attained in the venous vasculature to a value less than a predetermined value.
