Abstract: An adapter is employed to assist in the releasing of spring-loaded pushbuttons of the sort frequently associated with invalid equipment. The adapter comprises a collar, a plunger which passes through a hole in the collar, and a pressure plate connected at one end of the plunger. In the preferred embodiment the adapter is employed to release a pushbutton that locks an inner tubular telescoping member with respect to an outer tubular member. The collar is provided with an interior opening which may be force fitted into position around the outer tubular member. When correctly aligned, the plunger is located directly opposite the pushbutton to be depressed. By applying force from the palm of the hand to the pressure plate it is possible to depress the spring loaded release button and thereby unlock the telescoping members.

Abstract: A cup-shaped wheel having an abrasive rim is employed to edge grind the teeth of a circular saw to an improved contour. The grinding wheel is carried by a slide means which brings the grinding wheel into contact with the teeth of the circular saw. The slide means is also adapted to accomodate a drive motor for rotating the grinding wheel. An adjustble mechanism is incorporated into the slide means to adjust the angle of attack of the grinding wheel. In this manner the contour of the working surface generated can be varied at will. Since only point or edge contact takes place between the abrasive rim and the tooth, the wheel is essentially self-dressing. The method and apparatus are specifically adapted to grinding the carbide tip teeth of steel cutting saw blades. The relative movement of the machine elements is automatically controlled by a programmed electronic unit which, in turn, controls a system of hydraulic pistons.

Abstract: The guide bars of a warp knitting machine include a compensation means which allows the guides on the guide bar to pass more precisely between the gaps in the needles of an associated needle bed. The compensation means is located between a pattern wheel follower and a push rod which is rotatably attached at one end to the guide bar. An adjustable lever is attached at one end to the push rod and at the other end to a rotatable pin. The rotatable pin is associated with a housing which contains an eccentric roller cam. The eccentric roller cam is directly connected to the rotatable pin and is displaceable in direct response to the rotation of the rotatable pin. A short rod having an angled face is adapted to make contact with the eccentric roller cam. The other end of the rod is pivotally connected to one end of the push rod by a ball joint. When the guide bar is displaced from one needle bed to another the push rod and accordingly, the lever follow that motion.

Abstract: A circular saw includes a plurality of teeth having an improved metal breaking geometry. The saw is especially adapted to cut hard, brittle materials such as steel bars and the like. The saw teeth are generated by a cup shaped grinding wheel having a grinding face on its inside surface. By bringing the rotating inner surface of the grinding wheel into contact with each tooth, it is possible to produce a working surface on each tooth which exhibits improved metal breaking and self-cleaning characteristics. The working surface thus generated is characterized by the fact that all points on the working surface which lie in the same given plane perpendicualr to the axis of rotation of the grinding wheel are equally distant from any given point on that axis. The working surface is preferably a section of a cylinder or cone, but may exhibit irregularities or discontinuities for special applications.

The game is played by moving pieces having bar magnets therein about the regions. Some regions have bar magnets thereunder which either repel or attract the pieces. The game provides for automatic, in place, flipping of pieces which are repelled and for reprogramming of the positions of the magnets in the board.

Abstract: A multi-chambered scrubber is employed to thoroughly wash gravels or materials bearing heavy precious metals. The apparatus includes a multi-chambered scrubber drum which is supported at an angle by a frame and adapted to be driven by a variable speed drive system. The scrubber drum includes at least two sections each of which has a polygonal shaped, water-tight interior chamber.

Abstract: A vessel is provided for receiving a small quantity of a liquid to be observed optically. The vessel has a body provided with four upstanding side walls of which two opposite walls are transparent and optically true and are intended to lie in the optical path. The other two walls are much closer together so as to reduce the interior volume of the vessel and are provided with external vertical ribs so as to impart a generally square external configuration to the vessel. A U-shaped thermally conductive body is disposed with its bridge portion beneath the bottom of the vessel body and with its limbs upstanding between the ribs and in thermal contact with said other side walls. The vessel can be secured in position by means of the bridge piece which may be of dovetail shape or may be magnetic or provided with a permanent magnet.

Abstract: An improved steam boiler system includes an automatic means for injecting cool water into a steam bound boiler feed pump. In a first embodiment a pressure sensitive check valve detects the drop of pressure in the steam bound pump and in response thereto directs a cool water mist into the high side of the pump, thus reinitiating its operation. According to a second embodiment, cool water is sprayed into the pump in response to a drop of the water level in the boiler. In both embodiments, a vent line is used to bleed the high side of the centrifugal pump to a condensate tank in response to a drop of pressure in the pump. The vent line may be bled through a check valve or directly through a manual valve. Additionally, both embodiments employ a pressure sensitive valve in the boiler feed line, which shuts off the pump flow to the boiler whenever the pressure in the boiler exceeds the pressure at the output of the pump.

Abstract: Certain compositions have been prepared by the reaction of certain dyes of the class generally known as Color Index reactive dyes with certain support phases. The dyes utilized for said compositions all possess the general sulfanilido-triazidinyl-sulfoaryl group wherein the aryl groups may be phenyl or naphthyl and said general group is further bonded to aryl groups via an amino or azo linkage. It has been found that when aqueous fluids containing albumin, such as, for example, plasma or serum are passed over compositions within the scope of the present invention albumin is selectively adsorbed on said compositions without removal of other proteins present in the fluid. It has further been found that the albumin may be readily removed from the thus formed adsorbate without denaturing the albumin and leaving the solid phase dye composition in a suitable state for re-use without loss of activity.

Abstract: An improved pipe cap comprises a cover and a U-shaped handle pivotally connected thereto. The handle includes a pair of rounded lugs which are adapted to engage an annular groove in the pipe end when the pipe cap handle is rotated toward its locking position. When the handle is rotated away from the locking position and towards the unlocking position, the lugs cooperate with the groove so as to cam the cover off of the pipe end. This novel camming action helps to overcome the resistance frequently associated with breaking the seal between a pipe end and a pipe cap.An alternate embodiment of the improved pipe cap is fitted with lugs having a pronounced flat on one side. The alternative cap is intended to fit on a pipe adapter having a flat locking rim instead of a groove. The rim includes two slots 180.degree. apart which are engagable by an appropriate wrench to thread the adapter onto a fill pipe. The lugs on the cap are located in such a manner that at most only one lug can fall into a slot.

According to the preferred embodiments, the supports are provided with a means to pivot or slide the supports out of the way of tall or deep articles. Supports are adapted to automatically return to their initial position after a tray or similar article has been removed from the stand.
