Abstract: A device for use on a typewriter comprising a transparent sheet which is rotatable and translatable on the typewriter paper bar and may be positioned over a paper in the typewriter in front of type hammer striking position. The device aids in aligning a paper in the typewriter for insertion of a character in a previously typed paper.

Abstract: An alloy of 0.001-0.30 weight percent nickel, the balance being essentially tin. The alloy provides a brightness, smoothness, solderability and electrical conductivity comparable to gold and is electrodeposited from an aqueous bath containing nickel sulfate, nickel fluoborate, nickel sulfamate, stannous sulfate or stannous fluoborate, benzene sulfonic acid, sulfuric acid, fluoboric acid or sulfamic acid providing a pH not higher than 1, and a brightener. The concentration of the tin salt in the bath is at least about 1 oz./gal. and the weight ratio of the nickel salt to the tin salt is at least 0.20 to 1. Substrates which may be coated with the alloy include iron, nickel, silver and copper, alloys of copper, and aluminum or zinc coated with nickel, silver or copper, or any combinations thereof.

Abstract: A game device having a housing, comprising: two spaced apart upstanding support members; a first bar mounted horizontally within the housing between the support members; at least one open-ended, hollow cylinder loosely supported on the first bar, the cylinder having game indicia on its exterior surface; and an arm for momentarily imposing a force against the exterior wall of the cylinder, whereby the cylinder is caused to swing freely and eccentrically on and around the bar, and game points or results are determined by the positions of the indicia relative to a fixed point of reference when the cylinder is indexed by a projection member on a player actuated indexing member entering one of several apertures disposed circumferentially around the cylinder.

Abstract: A pump for dispensing small metered quantities of a liquid from a container such as a jar or can, the pump including a housing and a plunger, in combination with a valve comprising an annular washer having a rectangular cross-section, assembled between the pump housing and the plunger to provide tight seals throughout a plurality of annular surfaces, in order to prevent leakage in the closed position, and to tilt axially on the pumping stroke to permit escape of the liquid being pumped. Automatically opening container venting means is also provided.

Abstract: A horizontal multidirectional turbine windmill comprising a housing having apertures on all sides for ingress and egress of air and a rotor on a drive shaft within the housing, each aperture being the larger end of a funnel-shaped passage, the smaller ends of said passages being positioned to deliver air at relatively high velocities against the rotor buckets, the air entering the housing through one or more apertures on the windward side thereof and being exhausted through apertures on the leeward side. The housing is preferably so shaped that ambient air impinging on the housing surface without entering an aperture will flow around the housing and create a low pressure zone adjacent the exhaust funnel apertures, and the housing is also preferably so shaped that a plurality of units can be stacked vertically with their drive shafts coupled together. The rotor buckets are flexible and their profiles are varied automatically as a function of wind and rotational speed.

Abstract: A multi-hulled boat includes a main float and a retractable float normally arranged, when in their operative positions, in spaced apart side-by-side relationship. A float connection assembly is provided, including a pivot structure interconnecting the main float and the retractable float and arranged so that the float connection assembly may be pivoted with respect to the main float to move the retractable float to lie alongside the main float. The arrangement is such that the pivotable float connection assembly includes a beam which can be connected rigidly to the main float and the retractable float.

Abstract: A human epithelial heterploid liver cell line, such as line WRL 68 which forms individually separated islands or discrete clumps when cultured in a growth medium, has a morphology closely resembling that of hepatocytes of the human liver and a generation time not more than 24 hours, manifests increased production of glycogen in the presence of 1% glucose in the medium, and is capable of supporting viruses.Such cells may be advantageously used to provide cell cultures for supporting viruses for the preparation of viral vaccines.

Abstract: A vehicle chassis dynamometer for measuring available vehicle road horsepower is disclosed together with means for compensating an apparent dynamometer horsepower reading for dynamometer vehicle rolling resistance, and vehicle drive line losses, and adjusting for ambient barometric pressure, temperature, and fuel specific gravity to obtain an accurate reading of engine flywheel horsepower that may be used directly for comparison with engine manufactures SAE rated horsepower.
