Abstract: An anchor device adapted for securing mobile, modular and motor homes, trailers, campers and similar units, having an anchor for insertion into the ground on opposite sides of the unit, and a strap, cable or other flexible member extending over the unit from one anchor to the other. The device is mounted on the anchor and has U-shaped body and a reel shaft on which the end of the flexible member is wound. One end of the reel shaft has a transverse hole and the body has a lug with a hole adjacent the transverse hole in the reel shaft. After an adjustment has been made, a pin is inserted through the holes in the lug and reel shaft to hold the flexible member in a secured position. A slot means is provided on the other end of the reel shaft for receiving a tool for operating the shaft to tighten the flexible member.

Abstract: A hydraulic cylinder operated by ordinary home water pressure is used to actuate a swinging water closet. In accordance with a preferred embodiment of the invention, the water pressure and water discharge is obtained by a simple modification of a standard flush valve.

Abstract: An improved process is provided for the preparation of a gamma globulin suitable for intravenous administration from the readily available Fraction II or II + III plasma protein paste or from the corresponding fractions originating from placental extracts. The Fraction II or II + III paste is extracted with water at a pH of 4.9 to 6.0 and impurities are fractionally precipitated by addition of polyethylene glycol to 4% of wt./vol. and then 6% vol. ethanol. The desired gamma globulin is then precipitated at a pH 8.0 by addition of polyethylene glycol to 12% wt./vol.

Abstract: A rope spinning toy is provided having a spindle which can be grasped at either end and wherein one portion of the spindle is longer than the other and can be shortened by the user so that as the user becomes more expert, the spindle can be shortened. In accordance with one embodiment of the invention, an improved form of loop closure or honda is also provided which permits a light weight cord such as venetian blind cord of small diameter to be used to simulate certain rope-spinning feats that are customarily performed only with a heavier rope or lariat.

Abstract: An inexpensive polymeric device for releasably retaining a stack of perforated paper, including a pair of rake-like members each comprising a rail supporting projecting studs. The rake-like members are assemblable by inserting studs on each through the paper perforations from opposite sides of the stack and into sockets formed on the other rail to form a ladder-like assembly engaged with the paper. The rails on the ladder-like assembly are slid into close fitting channels defined on a backing strip which extends around the spine edge of the stack to keep the rake-like members in engagement, and are retained therein by end portions of the rails adapted to engage over the ends of the channels. Subsequently a user can squeeze together on cam surfaces on the end portions of the strips to simultaneously disengage them from the ends of the channels and move them into the channels so that the ladder-like assembly can be slid out of the backing strip and disassembled.

Abstract: A modular base for a waterbed or the like is provided wherein the base is formed of a plurality of discreet segments, preferably six, which may serve not only to support the waterbed but also for storage. In accordance with one embodiment of the invention, the modular elements are made of thin plywood which are set into a dadoed frame, greatly decreasing the cost and weight of the unit.

Abstract: A multiple hull craft such as a catamaran is provided having outrigger hulls which can be swung to either of two positions 180.degree. apart and locked in either position. The mast is swingable about a center structure through an angle of 180.degree. and is secured at either extreme. These features allow one to sail a boat after it has capsized as is hereinafter described in detail.

Abstract: A concave-convex structure is composed of a plurality of pole or rod elements including at least two series of rows of such rods, the rods of each row being substantially parallel to one another. The rows are intersecting, but are uniform in respective orientation. The rods are stabilized at the intersections by fittings which permit relative sliding movement of restricted degree. These fittings are secured to a flexible membrane or body portion.Modification of the fittings to provide multiple layer body portions is achieved through the application of spaced layers of material.

Abstract: An automatic laminating machine is provided for use with pre-fabricated laminating packets having a tear-off tab with a plurality of notches thereon. The machine is substantially automatic in its operation and can be easily operated by an inexperienced operator. The machine requires no warm-up time and heats up in only 10 seconds each time a packet is inserted. The machine will not operate unless it is used with a laminating packet with a pull tab of proper configuration which not only energizes the machine but also aligns the packet within the machine.

Abstract: A lettuce harvester is provided having a positive means for engaging the stems of lettuce to be trimmed whereby the trim cut is caused to take place at right angles to the stem and the lettuce is left ready for packing.

Abstract: A process is provided for the preparation of a gamma globulin suitable for intravenous administration from the readily available Fraction II or II + III plasma protein paste. The Fraction II or II + III paste is extracted with water at a pH of 4.8 - 6.5 and impurities are fractionally precipitated by addition of polyethylene glycol to 4% of wt./vol. and then 5% wt./vol. The desired gamma globulin is then precipitated at a pH 8.0 by addition of polyethylene glycol to 12% wt./vol.

Abstract: A combination wash basin and toilet fixture is provided wherein the wash basin is mounted over the toilet and swings out of the way to permit the use of the toilet. When the wash basin is swung over the toilet, the fixture appears to be an ordinary wash basin.

Abstract: A dismantling ladder is provided wherein the rails are made of different sizes with the rungs of a still smaller size so that one rail can be telescoped inside the other and a rung telescoped inside the smaller rail so that the ladder can be stored in minimum of space.

Abstract: A vending machine for newspapers or the like is provided having a single piece, clear cover which allows the merchandise to be viewed from various angles, which is easy to fill, and which protects the papers from exposure to the elements. The vending machine preferably incorporates an improved slide mechanism, making it substantially impossible to cheat the machine by obtaining more than one paper on a single operation of the slide release mechanism.
